First, safe operation 1, tractor field operation (1) Drivers must have technical training in agricultural training schools and get large and medium tractor driving licenses; tractors must obtain driving permits and license plates. (2) Before and after driving, the driver must strictly perform the inspection and maintenance work. The tractor must maintain its technical state and avoid “three leaks†(leakage, leakage, leakage). (3) Before starting, it is necessary to check if the cooling water of the engine is increased, whether the external bolts of the locomotive running system are tightened, whether the shift lever is placed in the neutral position and whether the hydraulic lifting handle is placed in the lower position. Before harvesting, the harvester must check the tightness of the triangle belt. If it is too loose or too tight, it will affect the service life of the harvester. Too loose a triangular belt will cause slippage and reduce work efficiency; over tightening of the triangle belt will increase bearing wear, increase power consumption, and may cause the shaft to be bent. In addition, the harvester must check the tightness of the sprocket before the operation, too tight and easy to wear, too loose chain to jump big, and even jumping off the teeth and the chain off. Once problems are found in agricultural machinery, it is necessary to promptly replace the defective parts, repair the fractures of the support plates and support frames, and ensure the technical integrity of the mechanical framework. The external equipment rust blocks should be stored after the entire vehicle is painted. To control the maintenance requirements, add lubricating grease to the agricultural implements being operated, tighten loose bolts, check for missing parts, and replace missing parts promptly. (4) When working in the field, the person must stay away from the car, stick to his work position, and forbid jumping up and down. The farm implements are firmly attached and the farm implements are not allowed to turn when they are not all raised. Reverse operations are strictly prohibited. When the locomotive is to be temporarily maintained, adjusted, overhauled, or cleared of wraps, it must be stopped and turned off. (5) When the vehicle is parked, the shift lever should be placed in a neutral position and it is prohibited to disengage the clutch for a long time. Before the engine stalls, the driver must not be far away from the locomotive. (6) Locomotives passing over fields and gutters should first cut the slope or dig out the gap and pass it at a low speed. In the event of a car trapping, do not increase the throttle rush and dig up the mud around the locomotive and the ground, fill it with straw, planks, etc., and pull it out with low speed or other vehicle traction. 2. Threshing operation safety production operation (1) Before operation: Carefully inspect, adjust and oil the various parts of the machine, and add protective devices around the drive belt. (2) Operation: Non-operators are not allowed to approach the machinery; open flames are not allowed; smoking is not allowed; no fertilizers are allowed to be worn; masts are not allowed to be fed into the machine by hand or wooden rod; inspection, adjustment, and oiling are prohibited And troubleshooting; no stones or iron can be fed into the drum. (3) After operation: Clean up the machinery in time, remove debris, repair and maintenance. “Safety First†is China’s consistent production safety policy. Agricultural machinery is a kind of labor method for agricultural production. With the increasing use of machinery, intense agricultural transportation, and continuous expansion of agricultural machinery operations, safety is particularly important. It is hoped that the majority of agricultural machinery operators will pay attention to the safe production of agricultural machinery and learn more about the knowledge of agricultural machinery safety in order to ensure that no accidents occur in the production of agricultural machinery. Second, security maintenance 1. Timely eliminate the weeds, dirt, and other deposits on the outside of the harvester and eliminate the straw, peels, debris, and dirt that are present inside the machine. All kinds of shells, thin iron parts and other rust-proof parts should be painted or fully painted to ensure that the appearance of rust-free spots. 2. After the maintenance is completed, ensure that each locomotive meets the requirements of “Four nets, three leaks, and one well-beingâ€, that is, oil net, water net, net net, locomotive net; no leakage, no water leakage, no air leakage; The state is in good condition before it can be stored.
