Film mulching planter: Hand push seeder is an ideal dry farming machine, which can complete multiple processes such as ridge shaping, side deep fertilization, film mulching on the ridge, and film side sowing, etc., with heat preservation, water saving, and fertilizer saving. , Save seeds, increase production, and increase income.

The end of the strips should be straight, and the linear deviation within the 50-meter seeding line should not exceed 8 cm.

The line spacing should be uniform, and the deviation from the specified line spacing in a broadcast should not exceed 1cm.

The depth should be the same, and the deviation of the seeding depth from the specified seeding depth should not exceed 0.5 cm.

The membrane should be tightly sealed, with a thickness of 3 cmD5 cm at the edge of the membrane, and the leakage and soil covering rate of the membrane edge should be less than 5%.

Adjustment of the metering amount: It is adjusted by changing the working length of the metering pulley and the gap between the metering tongues. The sown amount of winter wheat per mu is generally 5 kg-7 kg. Special attention should be paid to the fact that the actual sowing amount is equal to the working length of the pulley determined by the static test sowing amount multiplied by the slip correction coefficient, otherwise the sowing amount will be reduced.

The adjustment of the fertilization depth is achieved by changing the relative position of the shovel handle of the trencher and the plane on the frame. The general fertilization depth is 8 cm -12 cm.

Adjustment of ridge height: Turn the hand wheel to change the height of the ridge plate, thereby changing the enrollment depth to reach the required height, generally 5-10 cm. At the same time, it is necessary to adjust the angular position of the ridging board and change the amount of soil to meet the ridging standard.

Adjustment of the cover plate in the film-covered planter

Angle adjustment: When the tractor is running in the second gear, the rear end of the covering disc should be 2.5 cm away from the side of the trencher tube. The higher the speed, the greater the distance.

Height adjustment: The lower edge of the cover plate should be 1 cm higher than the seeding trencher.

Adjust the position of the ripper: loosen the fastening nut and move the ripper downwards, in accordance with the principle of the soil on the wheel pressure line of the ripper. The front end of the loosening shovel should be 5 cm below the fertilizing trencher.

Suspension adjustment: It is necessary to place the two pull-down rods of the tractor about 10 cm lower than the suspension shaft of the planter, and then hang the planter.

Corn Thresher's considerations

Choose the plot and the level of refinement. The ground after mechanical reinforcement must meet the technical requirements of "level, neat, loose, broken, clean, and moist". Running in the second gear and moving forward at a constant speed. The running speed of the unit is too high, which will affect the coating quality. The machine is not allowed to go backwards without lifting. Otherwise, related parts will be damaged. Troubleshooting, shutdown for maintenance. Shift maintenance, be careful. After the completion of each shift, it is necessary to carefully maintain, clean up debris, fasten parts, add butter, etc. After working in each season, it should be cleaned according to the instructions and stored in a rain-proof, dry and ventilated place.
