1、 Preparation before homework

1. Read the instructions
   Before operation, it is necessary to carefully read the user manual, familiarize oneself with the equipment structure, performance, and warning signs, and prohibit unauthorized operation.

2. Adjust key parameters

   • Row spacing and wheelbaseAdjust according to crop planting requirements to ensure matching with ridge spacing.
   • sowing densityDetermine based on variety, soil fertility (such as black soil, loess, sandy soil), rainfall, soil water storage capacity, and terrain height to avoid over dense planting.
   • Rack heightAdjust the height of the supporting wheel and reserve a copying amount for the copying mechanism to prevent component damage or excessive seeding.
   • Sowing depthAdjust the depth of each seeding unit uniformly through the depth limiting pointer handle. In actual operation, secondary adjustments are required to adapt to the soil preparation conditions.
   • Plant spacing and fertilizer application rateAdjust the transmission sprocket according to the sowing volume table, and measure the fertilizer discharge by rotating the support wheel 10 times to ensure that the fertilizer application per mu meets the requirements.

3. Trial broadcast verification
   Before the formal operation, a trial sowing of 20 meters is carried out to check the sowing quality and confirm that it meets the agronomic requirements before large-scale operation.

2、 Operational norms in homework

1. Traveling at a constant speed in a straight line
   • Maintain a constant speed of 8 km/h (maximum not exceeding 10 km/h, minimum below 3 km/h) during operation to avoid sudden changes in speed or stopping midway, which may result in replay or missed broadcasts.
   • The lifting seeder needs to be operated while in motion. When reversing or turning, the seeder must be lifted to prevent the trencher from being blocked or damaged.
2. Real time monitoring and adjustment
   • A dedicated person will follow the machine to monitor the rotation of the seed plate and fertilizer wheel, and promptly clean up blockages.
   • Observe whether the sowing depth is appropriate and avoid the phenomenon of "drying seeds" (seeds exposed to the soil surface).
   • Add seeds promptly when the amount of seeds in the seed box is less than 1/5, and the same applies to the fertilizer box; When transferring land, it is necessary to empty the seed box and fertilizer box, and it is forbidden to load heavy objects.
3. safety protection
   • It is prohibited to adjust, repair or lubricate components during the operation of the seeder. It is necessary to stop and clean the tangled grass or soil.
   • When sowing and mixing medicinal seeds, operators must wear protective equipment such as goggles, masks, gloves, etc. The remaining seeds should be properly disposed of and strictly prohibited from consumption.

3、 Special scenario precautions

1. Wide narrow row no tillage sowing
   • Ensure that the tractor travels upright, the sowing width alternates uniformly, the ridge spacing and wheel spacing match, and avoid dense planting.
2. Original ridge no tillage sowing
   • The ridge spacing and wheelbase need to be matched, and the tires should walk in the ridge groove; When the ridge is too high, it needs to be leveled, and when the straw or stubble is too thick, shallow rotation treatment on the ridge should be considered.
3. Ground and corner homework
   • Horizontal sowing should avoid crushing hard soil and choose a route that is convenient for planting and mechanical entry and exit.
   • When working on a slope, the slope should be less than 25 degrees. Drive along the slope direction to ensure the balance of the machine.

4、 Key points of maintenance and upkeep

1. routine inspection
   • Check whether the positioning sleeve of the seeding and fertilizing device is loose, and whether the seeding tube and fertilizing device are working properly during each shift.
   • Clean the blades, lock the components, check the gearbox oil level, and apply butter inside the transmission shaft expansion tube.
2. regular maintenance
   • Monthly MaintenanceReplace the gear oil, clean the seed box and fertilizer box, and check the wear of the gears.
   • Seasonal maintenanceDisassemble and clean the blade shaft and bearings, replace the oil seal, check the universal joint cross shaft needle rollers, and replace rusted or worn parts in a timely manner.
3. Parking management
   • Park in a dry and cool place, use wooden blocks to elevate the trencher and ground wheel, and apply rust proof oil to the exposed parts of the blade and input shaft.
   • Cover the seed box and fertilizer box tightly when parked outdoors, and cover them with rain cloth to avoid deformation of the rack.
