First, the adjustment method (take 3ZF-4 type as an example)
1. Line spacing adjustment. Adjustment of 3ZF-4 type potato cultivator and fertilizer spreader: Using the center line of the front cultivator beam as a reference, loosen the two sides of the cultivator and fertilizing machine to connect the fixing screws on the main beam, move the cultivating machine and measure the adjacent two blade tips. Center to the desired size and tighten the nut. It is required that the distance between each adjacent two blade tips is equal to the required line spacing, with an error of no more than 5 mm.
2. Spade shovel wing adjustment. The rake open wing adjustment is achieved by adjusting the bolt position of the shovel wing. Remove the fastening bolt, move the double wing opening to the desired angle, and then tighten the bolt in the corresponding hole. Note: The opening angle of the wings must be symmetrical with respect to the two sides of the monomer, otherwise it will affect the quality of the cultivator.
3. Adjust the depth of the soil. The depth of earth penetration is mainly achieved by adjusting the up and down position of the shovel on the frame. In intensive tillage fertilization operations in hard soils, remove the front limit roller, loosen the fastening screws, and adjust the up and down position of the shovel to meet the agronomic requirements. If the operation is in loose soil, install the limit. Deep wheel, adjust the depth position of the depth limit wheel and the rake spade, respectively, to meet the agronomic requirements.
4. Adjust the amount of fertilizer. The 3ZF-4 type potato cultivator applies between 7 and 45 kilograms per mu, which can be adjusted properly according to agronomic requirements. The specific adjustment method is as follows: tighten the fastening nut on the shaft of the row fertilizer device first, and adjust the effective working length of the row fertilizer tank into the row fertilizer tank so that the row fertilizer amount reaches the prescribed agronomic requirements (the row fertilizer tank extends into the row fertilizer tank Large working length, large amount of fertilizer, otherwise small).
Second, the operating procedures
First, the driving operation technology must be skillful, and it is necessary to go straight ahead, otherwise it will shovel off the seedlings and cause a decrease in production. Second, the tractor and the tractor will adjust the left and right suspension arms of the tractor lift mechanism horizontally and tighten the zipper of the suspension arm. , To minimize the equipment swing, keep it stable, to prevent injury; Third, we must often clean up the weed soil that is entangled on the working parts during the operation to keep the operation normal. After the end of each shift, we must completely remove the weeds on the equipment, tighten the screws on each part, and lubricate the bearings with grease. Fourthly, the equipment is found to be faulty and weeds accumulate in the operation. Fifth, under the hanging condition of the machine, maintenance work must not be performed under the machine to prevent injury.
