What are the methods for troubleshooting and eliminating rice planting machine problems

Rice transplanters play a vital role in agricultural production, but during use, they may encounter difficulties in starting or failure to start. At this time, you first need to conduct a comprehensive inspection of the battery to ensure that it is fully charged. Low battery power is one of the main factors leading to starting problems. Detect the battery voltage by observing the indicator light on the dashboard or using a voltmeter. If the voltage is lower than the standard value, the battery needs to be charged or replaced. At the same time, carefully check whether the battery connector is loose or corroded, and whether the cable clamp is intact. These factors may affect the contact of the circuit, resulting in difficulty in starting. If the connector is found to be loose, the clamping bolt should be tightened in time; if the connector is corroded, the battery pole head needs to be cleaned; if the cable clamp is damaged, it should be replaced with a new cable clamp to ensure the normal operation of the circuit.

When the rice transplanter can start but lacks power, it is usually a problem with the fuel supply system. At this time, check whether there is enough fuel in the tank, whether the fuel filter is blocked, and whether there is air in the oil circuit. Insufficient fuel will directly lead to poor fuel supply to the engine, thus affecting its power output; while the blockage of the fuel filter will hinder the flow of fuel and reduce the working efficiency of the engine; if there is air in the oil circuit, it will form an air barrier, resulting in the inability of the fuel to generate sufficient pressure, further affecting the engine power. Therefore, in response to these problems, it is necessary to add fuel in time, clean or replace the fuel filter, and tighten the joints of each oil pipe to ensure that the oil circuit is unobstructed.

During the operation, if the engine of the rice transplanter has abnormal exhaust, such as black smoke, blue smoke or white smoke, this is usually caused by incomplete combustion or oil entering the combustion chamber. The generation of black smoke may be caused by the blockage of the air filter, improper fuel supply timing of the injection pump, or poor atomization of the injector. Therefore, it is necessary to clean the dust on the air filter and the carbon deposits in the exhaust duct, check and adjust the fuel supply timing of the injection pump, and inspect the injection pump and the injector nozzle. Blue smoke may be a sign of oil leaking into the combustion chamber. Check whether there is too much oil in the crankcase, whether there is oil accumulation in the air filter, and whether there is mechanical wear on the engine body. For these problems, the excess oil should be discharged and the engine body should be repaired. White smoke may be caused by water in the fuel, or the cylinder head or cylinder liner is broken, or the cylinder gasket is damaged. In this case, the fuel should be precipitated, the accumulated water in the fuel tank should be released, the fuel should be replaced if necessary, and the engine cylinder should be repaired.

In addition, the walking system of the rice transplanter is also an area where failures frequently occur. It is very important to regularly check the rotation status of the load wheel, bracket wheel, lifting wheel and tension wheel and the amount of lubricating oil. When it is found that the wheel rotates abnormally or does not rotate, the defective parts should be replaced in time; if the lubricating oil is insufficient, it needs to be added to the specified oil level. At the same time, the wheel rim thickness of these wheels should be checked to see if it is too thin. If it is found that the wear is serious, it should be replaced in time to prevent deformation, rupture or scratching of the track due to insufficient strength. For the driving wheel, when the tooth thickness wear reaches 5 mm, the service life can be extended by adjusting the surface; if the tooth thickness wear on both sides is serious, it should be replaced in time to ensure the normal operation and operating efficiency of the rice transplanter.
