In order to use a good film covering machine, in addition to doing a good job in preparing preparations for membrane preparation, membrane preparation, and trial placement, attention should also be paid to the following two aspects. First, the correct operation 1. After laying the film unit into the ground, it should be aligned with the centerline of the ridge to be paved (,), pull the mulch back 0.5 to 1 meters by hand, and press the end and both sides of the film, and then the film wheel Press on both sides of the ground for formal operations. 2. During the operation of the unit, uniform speed and straight running are required. The animal husbandry traction filming machine should be drafted by a person to ensure the quality of the film. 3. During the operation, the auxiliary personnel should constantly check the operation quality of trenching, ridging, spraying, film coating, laminating, earth covering, drilling, and sowing. If problems are found, check the machine immediately. 4. When turning the unit in the ground, the amount of plastic film left in the ground should be cut and then artificially replanted, patched, and then pressed firmly. 5. After laying, put a small amount of soil on the membrane at intervals of 1 to 2 meters to prevent wind blowing. Second, common faults and exclusion 1. Horizontal wrinkles This is due to the fact that the longitudinal tensile force of the film is less than the transverse tensile force and the uneven forward speed. The solution: 1 reduce the pressure of the two left and right lamination rollers; 2 increase the clamping force of the film roll; 3 the forward speed of the unit should be uniform. 2. Longitudinal wrinkles This is due to the fact that the longitudinal tensile force of the film is greater than the transverse tensile force. The solution: 1 increase the pressure of the two left and right lamination rollers; 2 reduce the clamping force of the film roll; 3 properly reduce the unit forward speed. 3. The reason for oblique wrinkles is that the unit fails to drive straight when towing, or the pressure of the left and right diaphragms is inconsistent. Solution: (1) Improve the technical level of operation so that the unit can run straight; (2) Adjust the two lamination rollers so that the pressure is uniform. 4. The mulching of the film is caused by the unit's failure to drive straight, or the improper installation of the film roll and the uneven winding of the film roll itself. The solution: re-align the film roll, and with the unit forward direction; unit to uniform speed, straight line; check the film roll, replace if necessary. 5. The film can not hold down the film because the unit is not running properly, the width of the film is not matched with the surface and the quality of the film itself is not good. It should be solved according to the specific situation. 6. After the film is rolled and both sides of the film are curled, the pressure of the lamination roller should be increased, the declination angle of the shovel blade should be reduced, and the distance between the shovel blade and the plastic film should be adjusted. In the event of membrane rupture, the pressure of the two lamination rollers should be reduced to check the quality of the site preparation.
