As the weather warms up and the spring tillage preparation is about to proceed, what will be done to reduce the damage to the agricultural machinery? First, prepare before broadcast (1) Before the planting, we should carefully check the situation of the plot and be aware of it to ensure the quality of the operation and the safety of the machine. (2) Keep enough seeds, fertilizers and vulnerable mechanical parts to avoid delaying planting and delaying farming. (3) Seeds must be dry and clean, and must not be mixed with debris such as straw and stones, so as not to block the seed opening and affect the quality of sowing. When precision seeding, the seeds must be carefully selected, and the fertilizer is also clean, otherwise it will affect the quality of sowing fertilizer. (4) Put the seed fertilizer in the appropriate place in the ground to avoid delay in adding seed and fertilizer. Second, sowing precautions. (1) The sowing machine should try to avoid parking during operation. When it is necessary to stop, the planter should be lifted and backed up for some distance before planting. When descending the seeder, make the tractor run slowly. The seed drill must not be retracted when the opener is in the ground to prevent clogging or damage to the opener. (2) When the land is turned, the planter should be raised, the power of the metering device and the fertilizer device should be cut off, and the rowing and opener should be raised. (3) The manipulator must observe the operation status of the seeder at any time during the operation, paying particular attention to whether the metering device is to be planted; whether the row fertilizer device is to be used for fertilizers; whether to lose the seed and fertilize pipes; whether there is enough in the seed box and the fertilizer box. The species, fertilizer and other conditions. (4) After sowing a kind of crop, it is necessary to carefully clean the seed box so as to avoid seed failure caused by mixed seeds, resulting in the waste of seeds and causing difficulties and troubles for the field management in the future. After the sowing is finished, clean the fertilizer tanks in time to prevent corrosion of the machine. (5) When sowing seeds with pesticides, the sowing staff must wear gloves, masks, goggles and other protective tools. The remaining seeds should be properly and promptly handled so as not to pollute the environment and cause harm to humans and animals.
