I. Xinjiang - Type 2 1. Cause of roller jam (1) The engine power is insufficient. When the drum load increases, the speed suddenly drops to cause blockage. (2) The job clutch slipped. The common cause of slipping is grease on the friction plate, wear or damage of the friction plates, improper adjustment of the clutch clearance, etc. (3) The belt slips. In addition to the belt being heavily worn, loose, or stained with oil, it is a common cause for the tension nut to loosen and adjust the nut. (4) Improper roller speed adjustment. (5) The throttle is too small. (6) The position of the upper and lower bars on the manuscript draft wheel is improperly adjusted, and the roller jam is often caused because the clearance is too small and the mixture cannot pass through quickly. There should be a clearance of 5 mm to 15 mm between the upper grid and the draft roller cylinder, and a suitable gap of 30 mm between the lower grid and the draft wheel tip. If the installation of the upper grille is improperly adjusted, the draft roller will hang the straw when working; if the position of the lower grill is improperly adjusted, it will not play a guiding role for the straw, so that the roller can not be smoothly thrown straw backward, thus causing Blocked. (7) After the grid-shaped concave plate is clogged by the hybrid, it is not removed in time, so that the gap between the roller and the concave plate becomes smaller, causing blockage. (8) The harvester is not moving at the right speed. (9) Improper adjustment of the clearance between the drum and the concave plate. (10) The amount of feed is too large. 2. Reasons for the blockage of the remover The function of the stripper is to thresh again the non-depleted spikelets screened off from the rest of the sieve, return it to the clean sieve and clean it again. If the tail screen opening is too large during operation, the broken stalks entering the detacher will increase greatly, and the eliminators will soon be blocked. 3. The reason why the out of the augers blocked (1) The grain opening board is not opened or the bag change is not timely. (2) The belt is too loose. (3) Stems are wet or not mature enough. (4) The screw of the reversed blade of the auger falls off. (5) Broken drive chain. From the point of view of the cause of the malfunction, there are three types of measures to prevent clogging. First, most troubles can be prevented and eliminated as long as the maintenance and diligence are adjusted. Secondly, many plugging failures are caused by too much instantaneous feeding of crops. Generally skilled pilots can stop plugging as soon as they hear the sound of the belt slipping and then step on the clutch and increase the throttle. Third, require the manufacturer to improve the design. For example, an intermediate conveyor connecting the header to the threshing device is used by many manufacturers in conveying conveyor belts in conveyors, and in some plants, chain conveyors have been used to reduce plugging. Second, ZL-150 type 1. Causes of vibrating screen clogging. The connecting rod and the main shaft that transmit power to the vibrating screen are key-linked, and the long-time harvesting operation causes the large-side round hole keyway and the key of the connecting rod to be damaged, resulting in the connecting rod slipping on the main shaft and unable to transmit power. 2. solution. A φ5 mm radial through hole is drilled by hand from the outer surface of the large end of the connecting rod, and then a small piece of φ5 mm round steel is inserted into the hole and welded on the surface by welding. In the operation can also be managed to use bolts, so that the big end of the connecting rod hole does not slip on the spindle. Third, the Jinma 1065 The headers, rollers, and document handlers of the Jinma Model 1065 Combine Harvester are the most prone to plugging. 1. Header jam (1) Common causes. The distribution of the header of the auger was improperly adjusted, and the clearance between the bottom plate and the back plate was too large; the adjustment of the rotation speed and the height of the action point of the reel wheel was improper, resulting in a large “dead zone†between the reel wheel and the header, seriously affecting the entrance. Amount, causing congestion. (2) Control measures. Correctly adjust the position of the auger in distribution. When the agitator blade is severely worn, it needs to be repaired to get a proper clearance. The rotation speed and the point of action of the reel should be adjusted according to the density of the crop, the lodging condition and the locomotive forward speed. 2. Roller jam (1) Common causes. The speed of the drum is too low, or its speed does not match the forward speed of the locomotive, and the gap between the drum and the concave plate is too small. (2) Control measures. According to the actual condition of the crop, the rotation speed of the drum is controlled, and the speed is adjusted to the forward speed to properly adjust the gap between the drum and the concave plate. 3. Documenter jam (1) Common causes. Mai Meng blocked the "wave hole" on the drafting device. The consequence was a large amount of food waste. (2) Control measures. Regular removal of wheat straw on the document drafter can also be done with a gas pump. Fourth, John Deere Jialian l075 type The place where this type of harvester is most likely to clog is the pulverizer. (1) Analysis of the reasons. Due to the large engine power of this type of harvester, the forward speed and feeding amount are larger than that of the Model 1065. Although the grinder of this type of machine is wider than the Model 1065, it still cannot meet the requirements for grass removal and smashing. Therefore, it is often blocked and sometimes plugged one or two times within one hour, which greatly reduces the progress of harvesting. (2) Control measures. At present, the most effective method that can be taken by the use department is to appropriately slow the harvesting speed and reduce the load of the crusher according to the actual conditions of the crop. Another way is to change the blade of the grinder often, but this method is too expensive. Jilin rural network Rongcheng Jingyi Oceanic Technology Company Limited , https://www.jingyifoods.cn
