Common faults and troubleshooting methods of no-tillage planter for planting wheat

The main results are as follows: 1. The whole seed metering device does not plant seeds. The reasons are: lack of seed box, transmission mechanism does not work, drive wheel slip does not rotate. It should be filled with seeds, overhauled and adjusted the transmission mechanism to eliminate the slip factor of the driving wheel.

2. The single seed metering device does not sow seeds. The reasons are: seed wheel clamp, key pin loose rotation, seed pipe or seed mouth blockage. The seed metering wheel should be fastened again to remove the blockage at the seed transporting or seed mouth.

3. The sowing rate is uneven. The reasons are: the working speed changes greatly, the scraping tongue is seriously worn, the outer groove wheel clamp is loose, and the working range changes. The working speed should be maintained, the scraping tongue should be replaced, the working length of the outer groove wheel should be adjusted, and the clamp should be fixed.

4. The rate of seed fragmentation is high. The reasons are: the working speed is too fast, so that the transmission speed is high; the seed metering device is damaged; the size and shape of the seed metering wheel are not suitable; the scraping tongue is too close to the seed metering wheel. It is necessary to reduce the speed and work at a uniform speed, replace the seed metering device, replace the suitable seed metering wheel (plate), and adjust the distance between the scraping tongue and the seed metering wheel.

5. The sowing depth is not enough. The reasons are: the spring pressure of the trench opener is insufficient, and the pull rod of the trench opener is deformed, which reduces the angle of entering the soil. The spring should be tightened to increase the pressure of the trench opener, and the pull rod of the trench opener should be corrected to increase the entry angle.

6. The trench opener is blocked. The reasons are: the precision seeder landed too hard, the soil was too wet, and the trench opener fell into the ground and backed up. Should stop to clear the blockage, pay attention to sowing suitable moisture, and forbid reversing in the operation.

7. The soil cover is not strict. The reasons are: the angle of the cover plate is wrong, the spring pressure of the trench opener is insufficient, and the soil is too hard, so the angle of the cover plate should be adjusted correctly, the spring should be adjusted to increase the pressure of the trench opener, and the weight of the planter should be increased.
