Wheat No-tillage Planter Common Faults and Elimination Methods

1, the overall metering device is not seeded. The reasons are: Seed box is lack of seed, the transmission mechanism does not work, the driving wheel slips and does not rotate. The seeds should be filled, overhauled, and the transmission mechanism adjusted to eliminate the driving wheel slip factor.

2, monomer metering device is not seeded. The reasons are as follows: the seed wheel clamp, the key pin loosen and rotates, and the seed pipe or the following kind of plug is blocked. The seed wheel should be re-tightened to remove the input or plug underneath.

3, uneven planting. The reasons are: large changes in working speed, serious scratching of tongues, loosening of the outer sheaves, and changes in the working range. The uniform operation shall be maintained, the scraping tongues shall be replaced, the working length of the outer sheave shall be adjusted, and the clamps shall be fixed.

4, the high rate of broken seeds. The reasons are: the operation speed is too high, so that the transmission speed is high; the seeding device is damaged; the size and shape of the seed wheel are not adapted; the tongue scraping is too close to the seed wheel. Reduce the speed and uniform operation, replace the seeding device, use the appropriate seed wheel (disc), and adjust the distance between the scratching tongue and the seed wheel.

5, the depth of sowing is not enough. The reasons are: insufficient opener spring pressure; deformation of the opener drawbar, making the entry angle smaller. The spring should be tightened to increase the opener pressure; the opener puller should be calibrated to increase the inlet angle.

6, opener plug. The reasons are as follows: the precision seeder falls too fast, the soil is too wet, and the opener is reloaded after entering the soil. Stop and remove obstructions, pay attention to proper planting, and prohibit reversing during operations.

7, lax. The reasons are as follows: the angle of the earth-covering board is not correct, the spring pressure of the opener is not enough, the soil is too hard, the angle of the earth-covering board should be adjusted correctly, the spring is adjusted to increase the pressure of the opener, and the counterweight of the seeder is increased.
