Rice Destoner(LINAGGONG) complete sets of equipment are a kind of agricultural machinery commonly used in rice processing. Through processing rice, it can effectively remove impurities such as mixed stones and straw, and improve rice precision. The rice destoner machine completes the clogging phenomenon during use, which affects the processing process. Therefore, it is necessary to find out the cause of the blockage phenomenon in order to solve the problem, and preventive measures should be taken to prevent such failures from happening again in the future.

What is the cause of the blockage of the rice destoner machine?

The reason for the blockage of the rice destoner complete equipment may be related to the feeding speed. Each rice destoner machine has different operating speeds. If the user wants to increase the processing capacity and the grinding speed is at the same fixed value, the acceleration speed of the machine may be too fast, and the grinding impermeability may occur, which may lead to rice destoner equipment is clogged and the machine does not operate.

The complete set of Rice Grader(LIANGGONG) machine has the advantages of high efficiency, simple process flow, high degree of automation, low price and good quality of rice, and has been widely used by grain processing manufacturers. The problems that may arise during the use of the rice grader complete sets of equipment have caused problems for the users. To help you better solve a series of faults in the complete sets of rice grader, we will analyze the faults for the rest of the contents.

Analysis of the causes of the failure of the rice grader complete equipment:

1. The complete equipment of the rice grader machine is blocked and the output is reduced. The main reason is that the feed amount is too large, the discharge port pressure is too large or the discharge port is too small; the discharge port is blocked by the rice bran, which may be caused by the belt slippage, the roller wear or the rice knife wear; the raw material moisture is too high or the spiral head Wear and loose.

2. Rice bran contains rice, too much broken rice. The main reason: the rice sieve is damaged or the joint seam is too large; the conveying head and the sanding roller joint are not flat, the surface of the sanding roller is not smooth; the rice machine outlet is not smooth; the rice knife is too thick, the distance between the roller and the rice knife is too small; the rotation speed is unstable.

3. The current sudden increase. The main reason is: the feed inlet is broken, the pressure gate is out of order, the rice sieve is broken, the rice sieve bracket is broken; the foreign matter entering the machine or the feed amount is too large; the outlet pressure door is out of order, the rice sieve is blocked, the rice is not smooth; Or the manifold is blocked; the power is out of phase.

4. The rice grader machine complete equipment body accuracy decreased, uneven white. The main reason: the rice knife is worn; the feed is too small or the discharge pressure is too small.

5. The complete set of equipment of the drowning rice grader has large vibration and the bearing is hot. The main reason: the shaft or pulley is unbalanced; the anchor bolts are loose; the bearing is filled with too much oil or lack of oil; the lubricating oil is too dirty.

6. There is abnormal smell. The main reason: the roller is loose or broken; the foreign object is dropped inside the machine; the bearing and the seat are damaged; the belt is slipping; the nut is loose.

7. The accuracy of the rice grain is not uniform. Replace the roller; use the rice knife to adjust the head, adjust the surface, or replace the rice knife; avoid mixing different types of raw grain together; properly adjust the inlet jaw and the outlet jaw.

8. To much broken rice. Adjust the gap between the rice knife and the opening of the exit jaw, clean up the accumulated stack; re-adjust the speed of the roller; check the installation of the sieve to ensure the correct installation.

In the process of using Rice Grader(LIANGGONG), it is difficult to avoid problems with the machine. For some surface faults, it can be easily solved, but for some internal faults, it may be necessary to disassemble the rice grader equipment. Blind disassembly may cause more serious damage to rice grader equipment, so here are some things to be aware of when disassembling machinery and equipment.

Pay attention to the following points when cleaning rice grader equipment:

1. Use the appropriate tools when disassembling the rice grader equipment without slamming it to avoid damage or deformation of the parts.

2. Surface dirt and oil should be removed before disassembly, and should be kept clean during disassembly.

3. After the parts are disassembled, they should be stored according to the nature of the materials and the precision of the parts.

4. Disassemble according to the needs of rice grader equipment, disassemble as little as possible, and do not disassemble without disassembly.

5. When the rice grader equipment is disassembled, it must be prepared for assembly. In order to improve the assembly efficiency and ensure the correctness of the assembly, it is necessary to pay attention to check and mark the disassembly.

6. Disassemble the rice grader equipment in a reasonable order, usually from the attachment to the main part, from the outside to the inside, first disassemble the whole machine into an assembly, and then disassemble the assembly into parts and disassemble the parts into parts.

7. Before the washing and processing of rice grader machinery, the gas source and power supply should be turned off; if the rear part of the rice grader machine is equipped with electrical control accessories, the machine itself should not be washed directly with water, otherwise there will be a crisis of electric shock and damage to electrical operation.

In addition, it should be noted that when the rice grader equipment is running, it often leaves some impurities in the dead corner, and these impurities become very difficult to clean. Therefore, these impurities will cause the wear of the rice grader equipment to be intensified, and the quality of the processed flour of the rice grader equipment will be degraded. For some dead angles of processing equipment, difficult to clean parts, timely and reasonable cleaning.

The Paddy Husker(LIANGGONG) is a kind of separate sheller. It is suitable for customers with low voltage in rural areas, and there are customers of traditional rice mills. The rice is browned by the sheller and then milled into rice.

Principle of paddy husker:

The paddy husker consists of two working systems, rice milling and mites. The grain enters the grinding chamber from the hopper and is ground by the grinding wheel. After grinding, it is excluded from the rice nozzle. The shells and crucibles removed during the grain grinding process are partially discharged from the sugar sieve mesh outlet, and the rest of the airflow from the decanter is discharged when the grain is discharged from the rice spout. The two separated crucibles and shells are blown by the fan. Discharged out of the machine.

The whitening efficiency of grain is determined by the size of the grinding wheel, the number of machine revolutions, the pressure of the mill chamber and the resistance level. The gap (rolling distance) of the upper and lower discs is adjusted according to the size of the rice grain size. The rolling distance should be less than the length of the rice and greater than the width and thickness of the rice. The rice is fed into the lower sand tray from the feeding hopper through the central area of ??the upper sanding disc, and the centrifugal force generated by the rotation of the lower sanding disc forces the grain into the annular shelling area between the two plates. Under the action of end pressure and friction, about 75% of the rice can be removed from the husk, but there are more brown rice. The pressure of the mill chamber can be adjusted by controlling the grain flow rate of the inlet and outlet and changing the length of the grain flap. The resistance of the mill chamber may be adjusted by adjusting the position of the knife. The effect of the sweeping can be controlled by changing the position of the adjusting plate to change the airflow of the weir.

The Paddy Separator(LIANGGONG) is separated by specific gravity and is used to separate impurities with similar grain size and shape and different weights, such as stones, mud, metal pellets, glass, ceramics and cinder. There are two methods of separation: wet method and dry method: 1. The typical equipment of the wet method is a washing machine, which consists of a spiral water washing tank and a vertical drying part. 2. The dry process equipment has a specific gravity stone removal machine and a gravity classification table.

The paddy separator is separated according to the natural characteristics of the impurities. For example, the magnetic impurities can be separated to install a permanent magnet device in the feed chute of the grain processing machine, and the impurities adsorbed on the surface of the magnet steel are periodically cleaned by hand. It is also possible to use a permanent magnet roller or an electromagnetic roller, that is, a fixed semi-cylindrical permanent magnet or electromagnetic steel is installed in a non-magnetic roller, the grain flows along the surface of the drum to the outlet, and the magnetic impurities are adsorbed on the surface of the drum by the magnetic steel, and the roller Turn to the area where there is no magnetic steel and detach it into the collection container.

The paddy separator is separated according to the gas flow characteristics, and is separated by the speed at which the grain particles and impurities are suspended in the gas stream. This principle is applied to hand-cranked cars and belt-type field machines when artificially raised. The circulating air separator shown in Figure 9 can be used to remove light impurities from the grain.

The paddy separator is separated according to the degree of frictional impact resistance, and is used to separate impurities with poor resistance to friction, such as dirt and dirt adhering to the surface of the grain particles and grooves, awns, wheat wool and insect mites.

In addition, paddy destoner can be composed of two or more cleaning components with different functions to shorten the process, reduce the number of equipment, save plant area and reduce power consumption, especially for small and medium-sized processing plants.

In recent years, in some agricultural or advanced manufacturing related exhibitions, there are always some such machines - they look like a cabinet that stands up, and the interface is like a bank cash machine. The result is passed. Scanning code payment and other means to buy rice, the rice produced by this machine often carries a faint rice fragrance, giving a very comfortable feeling. This machine, which seems to be full of high-tech, is called a smart Paddy Separator(LIANGGONG). It is a machine used to mill rice for sale.

The intelligent paddy separator is another new attempt to apply technology to life. The process of rice milling and rice sales is connected through the Internet of Things, so that everyone can eat fresh and milled rice at home, and solve rice sales. Many problems in production. Because the intelligent paddy separator is now selling the rice, the rice that is now being milled has more nutrients than the bagged refined rice. Compared with the higher safety of bulk rice, it has accumulated a lot of popularity.

The intelligent paddy separator industry has not developed for a long time, but it has now been applied to many aspects of daily life. Intelligent paddy separators are generally used in places with large populations. The most common ones are placed in the community for people who live in the community to make daily purchases. The intelligent paddy separator placed in the community is generally larger in size, and the rice capacity in the barn is also larger to meet the demand for more people in the community. Generally, it only takes about half a day to check the amount of grain in the barn and the amount of rice bran bag. Add the rice in time, clean the fuselage every day, check whether the equipment is faulty, and it can run well, saving time and time. Peace of mind.

The safety inspection contents of the Rice Whitener(LIANGGONG) machine include: whether there is a reliable protective device in the dangerous part, whether the dangerous part has the safety warning sign in accordance with the national standard GB10396, and whether the instruction manual has detailed safety precautions to prompt the user to use the machine safely.

The adjustment found that there are more safety hazards in the use of rice whitener machines. In the 30 surveyed users, there are 28 households with product safety protection problems. Among them, there are 7 households with no protective devices installed at the time of shipment. There are 21 households that have been removed from the protective devices during use, accounting for the total number of surveys. There were 23.3% and 70% no safety signs or safety signs in the rice whitener machine, and there were 29 users who did not have a safety warning function, accounting for 96.7% of the total number of investigations.

When the rice whitener machine is working, the rotation speed can reach more than 1000r/min. Therefore, reliable safety protection devices and eye-catching safety warning signs are essential. In the investigation, it was learned that most rice rice whitener machines are equipped with safety protection devices and safety signs when they leave the factory. However, because the quality of safety signs is not good, many safety signs fade, blur or even fall off during use, and they do not play a safety warning role. The user's use process is dedicated to the maintenance and often the safety protection device is removed. These are the main reasons for the safety hazards in rice whitener machines.

In the past, the work of shelling and removing impurities from rice, this series of work needs to be done manually. As the demand in society increases, the daily output rate of enterprises must also rise. The disadvantage of manual production is low efficiency, and the working time is certain. The use of manual production is not only inefficient, but also high in production cost. However, if you are using Rice Huller(LIANGGONG) equipment, you don't need to worry about these problems.

1. When using the motor as the power, first make sure that the power cord is firmly connected, and also tightly wrapped and pay attention to the installation of the ground wire.

2. Must pay attention to continuous and evenly into the rice rod, and the amount of input should be appropriate. If the rice is intermittently put into operation, it will inevitably affect the production efficiency of the rice thresher. If the input of the rice is too large and the machine is overloaded, the machine will be stuck, which will cause the motor to burn and damage the equipment.

3. The user should pay attention to the water content of the threshed rice bar can not exceed 20%. If the water content is too high, the normal threshing effect will not be achieved, and even the phenomenon of threshing will not occur.

4. Before the rice huller equipment starts to operate, be sure to place it on a flat surface to ensure that the machine can operate smoothly and firmly, so as to avoid the machine from vibrating during operation.

Selecting a reasonable rotation speed to obtain a suitable polishing roller line speed is very important for reducing the broken rice rate and improving the polishing brightness of the rice. Generally, the line speed of the polishing roller should be 6-7 m/s. 3.3 The amount of water in the polishing chamber is polished at a certain ratio during polishing. Evenly spraying the water to wet the surface of the rice, which is beneficial to the separation of the surface of the rice grain, and at the same time, the starch is gelatinized to form a gel layer under the frictional temperature generated by the polishing pressure and the polishing process, thereby To achieve the purpose of improving the brightness of rice. However, if the amount of water is too large, the rice grains will flow abnormally, causing the pressure inside the Rice Polisher(LIANGGONG) machine to be too large, which will increase the crushing, and even lead to “boring car”. Therefore, in the use of the rice polisher machine, the water quantity should be controlled first, and the water quantity control is generally At around 0.5%.

The polishing pressure is established by the speed and impact force of the rice grains in the polishing chamber. The factors affecting the whitening pressure are various, but the polishing pressure can be adjusted and controlled by the pressure gate at the exit of the polishing chamber. The polishing pressure is large, the collision movement is severe, and the grinding is more broken after polishing; the polishing pressure is small, the collision movement is moderated, and the grinding is less after grinding. Therefore, a small polishing pressure should be used for polishing, but the polishing pressure is too small, which may affect the process. effect. The general polishing pressure is about 400-700 g/cm. 2.2.3 Line speed The polishing roll line speed is the main factor determining the speed and impact force of the rice grains. The line speed is low, the speed of the rice leaves off the iron roll is low, the collision movement is moderated, and the grinding is less after grinding, but the rotation speed is too low, and when the rice grain is not enough, the rice grain is partially crushed too much, and the over-grinding phenomenon occurs. Reducing the rice yield will also cause the rice to be partially ground insufficiently, unevenly polished; the line speed is high, the speed and collision force of the rice grains are large, the chance of rolling the rice grains is increased, and the polishing is uniform, but when the rice grains are over-rolled, the ends of the rice grains will be made. Being crushed and the broken rice increases will also lower the rice yield.
