Correct use of wheat thresher

Harvesting began. Harvesters could not be used in the mountains and some small plots. The thresher that had taken a year off had to go to work. In order to ensure the safe use of the thresher, some common knowledge about the maintenance and use of the thresher is introduced.

First, maintenance

1. Carefully and carefully overhaul before use. Before the wheat harvest, the thresher should be inspected and repaired in advance to check whether the bolts are loose, whether the bars are in good condition, and whether there are any problems with the transmission components. Find out the unsafe factors and eliminate them. Do not allow the thresher to operate with “diseases”. For the power used, both the diesel engine and the electric motor should be tested in advance to ensure that everything is safe.

2. Common intentions and causes of thresher.

(1) Unthreshing threshing: common causes include uneven feeding, large grain moisture, excessive threshing clearance, low drum speed, etc.;

(2) Unclear separation: Common causes include lack of air flow or wind direction, damage to the threshing machine screen or excessive clearance, and logic of grain wetness; tourists do not evenly enter grain, dry, or wet;

(3) Drum blockage: due to the fact that the grain is too wet and the feeding amount is too large, the rotation speed of the drum is too low, the winding of the roller stalk causes winding, the power is insufficient, or the voltage is too low;

(4) Grain crushing: The reason is that the threshing gap is too small, the rotating speed of the drum is too high, the grain is unevenly fed, and the wet and dry seasons are too dry;

(5) drum noise: loose bolt bolts, concave plate deformation, threshing clearance is small;

(6) Motor overheating: Excessive feeding leads to too much load, poor ventilation, poor heat dissipation, low voltage, or misaligned conductors.

Second, use

1, can not be overloaded. One is that the machine is not overloaded and the thresher cannot be overloaded. Whether it is powered by an electric motor or a diesel engine, it cannot be overloaded during operation, otherwise it is unsafe. The second is that the personnel are not overloaded and the continuous operation time is not long. When wheat is threshed, it often takes days and nights. However, the continuous operation time should not be too long. After 5-6 hours of general work, it is necessary to take a break and take a break. Its power machine carries out safety inspections and gives people a rest, so that the machinery is maintained. Otherwise accidents can easily occur.

2. Mobile and installation are operated by professionals. It is not allowed to move and install the thresher at will. The movement and installation of the thresher and its power machine must be operated by skilled professional technicians. Do not do it yourself. When moving the electric thresher, it is necessary to turn off the power first, and the insulated wires must not be dragged on the ground to prevent the insulating layer from being worn, causing electric leakage and causing injury. The shutdown and start-up of the diesel engine should all be checked by a professional before operation.

3, safety devices to complete. The safety devices on threshers and power machines must be complete and effective. If the transmission belt must have a safety shield, the motor housing must have a grounding wire. This is a safety cord that ensures the safety of the operator.

4, to strictly prevent fires. Where it is prone to fire in a wheat field and requires the use of a diesel engine as a power source, a fire shield must be installed to keep the surroundings of the power machine clean. The lighting used must also have fire protection measures and keep away from combustibles. Workers are strictly forbidden to smoke on wheat fields, especially straws.

5, operators should train. People who use a thresher must first train and take up posts. Through training, you should understand some mechanical operation and safety knowledge, and have practical experience. Avoid patching up personnel temporarily, otherwise it is very easy to have mechanical accidents.

6, the number of workers should be appropriate. The number of people participating in threshing should be appropriate and the division of labor should be clear. The more the better, the better. With more people, it is not only a waste of manpower, but it is also confusing on the spot and it can easily lead to unexpected accidents.

7. Straw feed should be uniform, adequate, and safe. When threshing machine threshing, we should pay attention to even feeding, the amount of feeding is appropriate, the straw can not be fed together, otherwise it will easily damage the parts and harm the human body. The human arm must not reach into the feeding port to prevent injury by a high-speed rotating pattern or even to cut the arm.
