Corn seeder fault detection

1, the seed meter is not needed. The main reason is that the transmission gears are not engaged, or the square holes of the sorting shafts are worn, adjusted, repaired or replaced.

2. Individual seed metering devices do not work. The reason is that the seed scaffolding or the corn planter device port in the individual seedbox is blocked by the sundries, and the sundries should be cleaned; the connecting pin of the corn planter shaft and the individual seeding trough is broken, and the pin should be replaced; the individual seedbox inserting plate If it is not pulled open, the board should be pulled apart.

3, seed metering, but there are no seeds in individual species. The reason is that the opener or the seed tube is clogged (mostly on the opener of the ground wheel), the blockage should be cleaned, and corresponding measures should be taken to prevent debris from falling into the opener.

4, the seed does not stop, lose control. The reason is that the separation pin of the clutch strut is detached or the separation gap is too small, and the pin should be reinstalled and locked, or the separation gap should be adjusted.

5, when the seeding is intermittent, the seeding is uneven. The reason is that the transmission gear meshing clearance is too large, the gear slips, and should be adjusted; the clutch spring elastic force is too weak, the gear should be slippery, and the spring should be adjusted or replaced.

How to use corn planter

The corn planter has the characteristics of uniform seeding, uniform depth, stable row spacing, good soil covering, seed saving and high work efficiency. The correct use of the planter should pay attention to the following 10 points:

1. Maintenance before entering the field should clean up the sundries in the seeding box and the grass and soil on the opener to ensure good condition, and fill the transmission and rotating parts of the tractor and planter according to the requirements of the manual. Lubricating oil, especially before each operation, pay attention to the lubrication and tension of the drive chain and the tightening of the bolts on the planter.

2. The rack cannot be tilted. After the seeder is attached to the tractor, it should not be tilted. When working, the rack should be horizontal.

3, do a good job of various adjustments According to the provisions of the instructions for use and agronomic requirements, the amount of seeding, the spacing of the opener, the depth of the grooved soil pressure roller is adjusted appropriately.

4, pay attention to add seeds to the seed box seed, to achieve no small, sputum, miscellaneous, to ensure the effectiveness of the seed; secondly, the seed box should be added at least to cover the entrance of the seed box to ensure seeding Smooth.

5, trial broadcast In order to ensure the quality of sowing, before carrying out large-scale planting, we must insist on trial broadcasting 20 meters, observe the work of the planter. Consultation with agricultural technicians, local farmers, etc., confirming that the local agronomic requirements are met, and then planting large areas.

6, pay attention to the uniform speed of the agricultural machine to choose the operation of the walking route, should ensure the addition of seeds and machinery in and out convenient, sowing should pay attention to uniform speed straight ahead, can not be slowed down or stop midway, so as not to replay, missed; to prevent trenching The device is clogged, the lift of the planter is to be operated while traveling, and the planter should be lifted when turning backwards or turning.

7, first broadcast the ground First, cross the ground, so as not to harden the ground, causing the broadcast depth is too shallow.

8. Frequent observations When planting, the working conditions of the seed metering device, the opener, the covering device and the transmission mechanism are often observed. If clogging, clay, entanglement, and seed coverage are not strict, it should be eliminated in time. Adjustment, repair, lubrication or cleaning of grass wraps must be done after parking.

9. Protecting the corn planter  When the seeder is working, it is strictly forbidden to reverse or turn sharply. The lifting or lowering of the seeding machine should be carried out slowly to avoid damage to the machine.

10. Pay attention to the seed box. The seed in the seed box should not be less than 1/5 of the volume of the seed box during operation; when transporting or transferring the land, the seed box should not contain seeds, and can not be loaded with other heavy objects.
