[0002] Seed dressing technology in wheat planting is an important agricultural measure. The main purpose of wheat seed dressing is to prevent and control pests and diseases and improve seed germination and emergence rates. Through seed dressing, pesticides, fungicides and other agents can be evenly attached to the surface of seeds to form a protective layer, effectively preventing soil-borne and seed-borne diseases and underground pests.

[0003] When dressing wheat seeds, choose appropriate insecticides and fungicides according to the occurrence of local wheat diseases and pests. Choose high-quality wheat seeds, clean the seeds and dry them. Dilute the agent to an appropriate concentration, mix the diluted agent with the seeds thoroughly, and ensure that each seed is evenly coated with the agent.

[0030] A box cover 7 is detachably installed on the top of the planting and seed mixing box 1, and a filling bucket 4 that is interconnected with the inside of the planting and seed mixing box 1 is fixedly installed on one side of the upper end surface of the box cover 7. The arranged filling bucket 4 can facilitate the delivery of wheat seeds, so that the delivered wheat seeds can be mixed in the planting and seed mixing box 1. A plurality of legs 8 are fixedly installed at equal angles on the bottom end of the planting and seed mixing box 1, and the planting and seed mixing box 1 can be stably supported by the plurality of legs 8.

[0031] By adopting the above technical scheme, when in use, the wheat seeds are put into the planting seed dressing box 1 through the filling bucket 4, and the feeding pipe 301 is connected with the pesticide feeding device, so that the feeding pipe 301 can be fed into the conveying channel 304 through the shaft sleeve 302 and the connecting hole 303, so that the pesticide in the conveying channel 304 can be conveyed to each single-layer channel 305, and then the pesticide is conveyed to each multi-point injection hole 306 through the single-layer channel 305.
