First, custody is not good. When the harvest of summer and autumn grain is over and the thresher is no longer used, the thresher should be thoroughly scrubbed and placed indoors for storage. It should not be thrown on the ground or on the side of the field, letting the wind and rain, causing the parts to rust and damage, leaving Unsafe hidden dangers.
Second, do not overhaul before use. Before harvesting summer and autumn grain, the thresher should be carefully inspected and repaired to see if the bolt is loose, the rod is intact, and the transmission parts are in trouble. Find out the unsafe factors and eliminate them. Don't take the disease.
Third, overload work. No matter whether it is powered by an electric motor or diesel engine, it can't be overloaded during work, otherwise, it is very unsafe.
Fourth, free to move and install. The movement and installation of the thresher and its powerful machine must be operated by skilled professional technicians. When moving the electric thresher, the power must be turned off first, and the insulated wires should not be pulled on the ground to prevent the insulation layer from being worn, causing electric leakage and injury. The shutdown and start-up of the diesel engine should be checked by a professional before operating.
Fifth, the safety device is not complete. The safety device on the thresher and its powerful machine must be complete. If the transmission belt must have a safety shield, the motor must be grounded to ensure personal safety.
6. The temporary patchwork of threshing personnel. Those who use a thresher should have some knowledge of mechanical operation and safety and have practical experience. Do not temporarily put together people, otherwise, it is easy to have an accident.
7. Straw feeding is uneven. When threshing in the thresher, attention should be paid to uniform feeding, and the feeding amount is appropriate. The straw should not be fed in bundles, and the foreign matter mixed with the straw should not be fed together, otherwise, the parts and the body may be damaged. The human arm must not reach into the feeding port to prevent it from being injured by the high-speed rotating rod or even interrupting the arm.
Eight, many people are mixed. The number of people participating in threshing should be appropriate, not as much as possible. More people, not only waste manpower but also easily lead to unexpected accidents.
Nine, continuous operation time is too long. When harvesting threshing in summer and autumn, it is often necessary to fight day and night. However, the time for continuous operation should not be too long. After 5-6 hours of work, it is necessary to stop and rest and carry out safety inspections on the thresher and its powerful machine to enable people to rest. The machine is maintained, otherwise, it is prone to accidents.
X. Use self-made and eliminated threshers. In order to save money, some people make homemade threshers or use old de-granulators that are eliminated. This type of thresher is inferior to the thresher that has been rigorously tested and cannot be used.
