Matters needing attention in harvesting potatoes by machine

When harvesting potatoes by machinery, in order to save time, labor and labor, and to improve the economic benefits of the use of machinery and the commodity rate of potatoes, we should pay attention to the following problems.

The main results are as follows: (1) about 10 days before the harvest time, the seedlings should be rolled or cut first (the method of rolling seedlings is to thread the waste tires into a string and drag the seedlings with a tractor) to make the potato skin aging and prevent the potato from breaking during harvest and affecting the quality of commercial potato.

(2) the matching of potato pickers for each unit should be reasonable, the small harvester is generally equipped with about 12 people, and the large harvester is equipped with about 40 people, so as to ensure the rational use of personnel, so that the machines and tools are neither idle nor a waste of labor.

(3) before the official start of the harvest operation, the machines and tools should be debugged on the ground, and a trial harvest should be made. Special attention should be paid to adjusting the depth of the plough shovel into the soil. If it is too shallow, it is easy to hurt the potato, and if it is too deep, it will increase the load of the tractor and affect the separation quality of potato soil. Too deep and too shallow will affect the clean rate.

(4) drivers should concentrate their energy to ensure that the probability is straight and the speed is relatively stable so as to prevent damage to potatoes. If the soil is viscous and humid, you should go slowly. The throttle is as large as possible to increase the engine speed, so as to improve the running speed of the dithering screen and achieve a good separation of potato and soil. The unit should grasp the opportunity of take-off and landing when taking off and landing on the ground to prevent missed take-off and landing, and should be aligned when dropping the shovel.

(5) the tractor shall disconnect the power connection between the tractor and the farm tools when towing or hanging the machinery to transfer land or short distance transportation, and shall not seat people or place other objects on the equipment. When crossing the ditch ridge, the unit should go slowly to prevent damage to the equipment.

(6) when the equipment is raised, it is strictly forbidden for personnel to carry out inspection and repair under the equipment, so as not to cause personal casualties. Grease should always be added to the lubrication point of the machine.

(7) often clean up the weeds and potato seedlings that clog the machines and tools, clean up the stones carried by the shaking screen, and clean the soil at the tip of the plough and shovel.

(8) the tightness of the dithering screen should be economically checked and adjusted in time. Too loose and too tight will affect the separation quality of potato soil and the service life of the conveyor belt.
