6 rice transplanter experience

1, how to replace the chain South Korea International brand rice transplanter after using the operation 2 years, often broken chain chain chain phenomenon. The reason for this is that the pitch of the chain is increased due to wear, and the discount is stuck during transmission. Axle chains are expensive and difficult to install. There are a lot of drivers who cut the axle chain box transversely and change the chain before welding. The disadvantage of this method is that the chain box is easy to deform after welding, the coaxiality of both ends of the shaft is poor, and the support strength is not enough. In fact, the following simple method of replacing the chain can be used:

1 Pull out the broken chain; or put the small shaft end of the axle chain box upward, make the chain leak out from the lower shaft hole, and disconnect the chain.

2 With the shaft hole end of the axle chain facing upward, place one end of the new chain inward from the hole.

3 Turn the lower sprocket shaft until the chain is engaged by the sprocket.

4 Turn the small end of the axle box up and continue turning the small sprocket.

5 When both ends of the chain are in the position of the shaft hole, connect it.

2. In the hydraulic system, it is necessary to use oil. A Yasiya transplanter is normal at the beginning of operation. Later, the landing is getting slower and slower. Finally, it cannot rise. After the cleaning has improved, but still not sensitive. Check the oil circuit and all the valves are no problem, but there are aluminum alloy debris in the hydraulic oil. Disassemble the gear pump and check that the gear scratched the casing and the alloy debris blocked the outlet. Analysis believes that this fault is caused by improper use of oil.

3. The leech transfer pump should periodically check a Yasiya transplanter purchased in 2002. In the spring planting season in 2004, it was found that the picking volume was small and the mound box moved slowly. After many adjustments, it could not be solved. According to the analysis, the slow movement of the trunk is the key reason. The hydraulic transverse transfer pump was dismantled and checked, and it was found that the transfer pump plunger was worn and the output oil amount was small. From this it can be seen that the operation of the transfer tank pump should be checked regularly.

4, pay attention to the operation of the lubricated pull bar to control bar includes refueling bar, the main clutch pull bar and steering clutch pull bar. In the second year of operation of a rice transplanter, rust stagnation occurs due to the operation of the pull-bars to trap water into the mud, affecting the normal operation. Therefore, after the end of each operation period, the upper part of the pull sleeve should be dripped with oil and the operating mechanism should be frequently pulled until oil droplets appear on the lower part of the pull sleeve.

5. The drive belt should be removed and stored. The first two years of operation of the Yasiya transplanter is normal. In the third year of operation, the speed of the planting arm is obviously reduced, and it is not even rotated. There are no obvious effects in debugging. Open the continuously variable transmission belt cover plate inspection and found that the belt slipped seriously. Experience has shown that CVT belts must be taken out of storage after the end of each operating season, and the tightening degree should be checked during the second year of installation and replaced when necessary.

6, should use the high number of unleaded gasoline commonly used imported rice transplanter petrol engine without gasoline filter parts, if the use of unclean low-grade gasoline, impurities will form a carbon deposit in the air inlet, so that the valve is stuck or stuck, In severe cases, the gasoline engine will malfunction in five to six days. According to the requirements, imported rice transplanters must use pure high-grade unleaded gasoline.
