First, technology introduction Mechanized harvesting of wheat refers to the use of machinery instead of manpower for harvesting, tying, transporting, stripping, and clearing during the ripening period of wheat to achieve the purpose of reducing food loss, looting farmers' labor intensity, and promoting labor transfer. Commonly used wheat harvesting machines include combine harvesters and windrowers. Among them, the windrower can only complete a single harvest, and the operations of baling, transporting, removing and cleaning still need to be completed manually. Second, the operating specification 1, suitable land. The surface is smooth without stones, and the slope along the direction of the unit is not more than 6 at the time of harvesting. The surface humidity should ensure the normal operation of the unit, the crop plant height is 700mm-1000mm, and the output is more than 3000kg/ha. . 2, timely harvest. The ripening stage of the crop is wax-matured, the grain moisture content is 18%-25%, the stem moisture content is below 50%, the crop lodging angle is not more than 10, and the wind force is not more than 3m/s. 3. Horizontal channels in the plots should be leveled before harvesting. Locally fallen serious crops were harvested by hand. The four sides of the plot should be manually harvested, and the cut crops should be removed immediately to facilitate turning the unit. 4. Harvesting with the combine harvester, performance requirements of the harvesting equipment: total grain loss rate ≤ 1.5%; impurity content ≤ 2%; crushing rate ≤ 2%; use reliability: validity ≥ 90%. Straw chopping quality requirements: chopped length is less than 10cm; standard length of cutting length is ≤ 2%; relative error of cutting length is ≤ 13%; use reliability: effective degree is ≤ 90%. 5. When cutting with a windrower, the cutting shall meet the local agricultural technical requirements, generally about 7-15 centimeters; the root difference is ≤150mm; the angle of the windrower is 9020; the difference between the laying angle is ≤20; Under the conditions, the total loss rate is ≤ 0.5%. Third, supporting equipment Common large-scale wheat combine harvesters mainly include Xinjiang No. 2 and Futian Gushen. Small combine harvesters mainly include 3L-0.5, 4L-0.75 and 4LD-150 types. Windrowers mainly include 4GL series self-propelled windrowers. Fourth, pay attention to matters 1, start. Before starting the unit, the shift lever should be placed in neutral; the power input clutch of the thresher is placed in the disengaged position and then started. For a dual-power model equipped with an additional diesel engine, the power of the rear thresher must be engaged before the operation starts. After the start of the operation, the power of the header can be engaged to allow the tractor to walk. 2. The unit started. Before starting the unit, the harvester transmission clutch should be closed to make it work. At the same time, pay attention to observing whether there are people or obstacles in the front and rear of the unit and do a good job of safe operation so as not to hurt people or damage the property. When connecting power, turning, and reversing, honking. 3, the field passes. The unit should reduce speed and drive cautiously in case of harsh road conditions, such as a ditch gorge, so as not to cause excessive impact and damage the machine. 4, pay attention to observe the fault. During the operation, the operator should concentrate on observing and listening to the operation of various parts of the machine and master the throttle according to the load. If it is found that the machine is running abnormally and there is abnormal noise, immediately disengage the power gear, stop the inspection, and discharge the fault. Do not remove the fault while the machine is running. 5, the operator. When the crew is working, the operator limits the ride.
