Medium-sized agricultural machinery straw crushing and returning machine how to maintain the effect is good?

Using medium-sized machinery to return straw to the field can increase the content of soil organic matter, improve soil fertility and promote the continuous yield and income of crops. So straw crushing and returning machine how to maintain the effect is good?

1. Preparation before operation: carefully check whether the connection of each part is reliable, whether the fastener is loose, and whether the rotating part is flexible. To inspect the tool holder and blade one by one and find deformation damage or shortage, it should be repaired, replaced or replenished in time. And check to adjust the tension of the triangle belt, add lubricating oil and grease as required. At the same time, after being properly hooked up, it is necessary to transfer by air for 3-5 minutes and confirm that each part is operating normally before it can be put into operation.

2. Key points of operation: after the unit enters the ground, the suspension member of the tractor should be adjusted first to keep the front and rear, left and right of the machine horizontal, and pay attention to adjust the height of the limited deep wheel in order to maintain a reasonable stubble height and strictly prevent the blade from entering the ground. Different working speeds should be adopted according to crop density and growth, soil moisture content and firmness, and the tension of the transmission belt should be observed at any time. If it is too tight, it should be adjusted in time. When connecting the power output shaft, it is necessary to have a low-speed no-load, and only after the engine accelerates to the rated speed can the unit start slowly and put into load operation. It is strictly forbidden to start the field returning machine or the unit with load to avoid damage to the parts, and it is not allowed to turn or retrograde with load. When the unit moves the land, the power should be cut off. It is strictly forbidden for non-operators to approach or follow the operating unit to ensure personal safety.

3. Maintenance after operation: the accumulation in the rotating part and the soil layer on the inner wall of the guard plate should be removed in time, and the rotating parts and fasteners should be inspected, adjusted and replaced in time, and butter should be injected into each lubricator. When not in use for a long time, should also do a good job of anti-corrosion treatment of exposed parts, blades should be oiled for safekeeping, and the machine products should be stored in a dry, ventilated, transparent warehouse, such as open storage, rain protection, sun protection facilities should be added.

Note: the adjustment method of straw returning machine before use.

Before the operation of the straw returning machine, the machines and tools shall be technically inspected according to the technical conditions of factory product acceptance and appraisal, and the trial operation, adjustment and maintenance shall be carried out according to the instructions. The technical state that should be maintained by matching tractors or corn combine harvesters. After connecting the power with the equipment, conduct a comprehensive inspection.

1. Installation of universal joint. Must pay attention to three points: ⑴ should ensure that the straw returning machine in the work, the square shaft, casing and fork neither top death, but also have sufficient fit length; ⑵ universal joint should be installed correctly, if the direction is wrong, it will produce noise; ⑶ universal joint square shaft, square sleeve length and active and passive pulley diameter, according to the size of the tractor suspension mechanism and power output speed is different, purchase and use should be selected according to the instructions.

2. Adjustment of machines and tools. After the returning machine is connected with the tractor, it is necessary to adjust the left and right level, the front and rear level and the stubble height of the operation. The length of the main pull rod is adjusted to keep the unit horizontal, the length of the stay rod is adjusted to keep the unit horizontal, and the position of the hydraulic handle is determined according to the operation quality requirements and the condition of the ground. control the stubble height and the lifting height when turning the ground.

(1) left and right horizontal adjustment. Adjust the cable-stayed rod to make the machine horizontal, and at the same time, adjust the lower connecting shaft to the long hole so that it can float during operation.

(2) horizontal adjustment before and after. Adjust the middle lever so that the machine is horizontal in front and back.

(3) adjustment of stubble height. The clearance between hammer and claw or throwing knife should be adjusted according to soil firmness, crop planting form and surface leveling condition. Lift the returning machine, loosen the fastening screws on the lifting lugs on both sides of the drum, adjust arbitrarily in the upper and lower holes, increase the stubble height down, lower the stubble height upward, and tighten the screws after adjustment, it can also be adjusted by changing the lifting rod, but the first method is the best.

(4) adjustment of tightness of triangular belt. If the belt is too loose, the nut on the tensioning wheel frame can be adjusted inward; if the belt is too tight, the nut can be adjusted outward.

(5) the adjustment of gear clearance of gearbox. After the straw returning machine works for a period of time, the axial clearance of the driving shaft and the meshing clearance of bevel gears change due to wear, which can be adjusted by increasing or decreasing the adjusting gasket.

3. Before operation, check whether the parts are in good condition and whether the fasteners are loose, and add gear oil to the gearbox. In general, the oil surface height should be immersed in the oil surface of the big gear 1 stroke 3, and each lubrication part should be filled with butter.

4. after the inspection, the idle operation should be carried out for 5-10 minutes, and the operation can only be carried out after confirming that the parts are in good condition.
