Coating device for watermelon seeds

Abstract

The invention discloses a coating device for watermelon seeds. The coating device for watermelon seeds comprises an air duct, a liquid spraying tank, a material collecting box and a spiral conveyor, wherein a material inlet tube is fixedly installed at one side of the top of the spiral conveyor, a material inlet hopper is fixedly installed at the top of the material inlet tube, and the material inlet tube communicates with the spiral conveyor; the air duct which is fixedly mounted on the material inlet tube is parallel to the spiral conveyor, an air inlet is formed in one end of the air duct,and an air outlet is formed in the other end of the air duct; a fan is fixedly installed on the inner wall of one end of the air duct through a bracket, the other end of the air duct communicates withthe outside, and a filter plate is fixedly mounted in the material inlet tube. The coating device has a simple structure and convenient operation, and hollow shells, residues and dust in the seeds are blown off through the fan, so that the germination rate of the seeds is improved, and unnecessary waste of chemicals is reduced; since excess chemical liquid can be pumped into a chemical preparation box through a second delivery pump, the chemical liquid can be reused, so that unnecessary waste of the chemical liquid is reduced, and the processing cost is saved.

Description

technical field [0001] The invention relates to a coating device, in particular to a coating device for watermelon seeds. Background technique [0002] Seed coating refers to the use of adhesives or film-forming agents to wrap non-seed materials such as fungicides, insecticides, micro-fertilizers, plant growth regulators, colorants or fillers on the outside of the seeds to achieve spherical or A seed technology that basically maintains the original shape, improves disease resistance, accelerates germination, promotes seedling formation, increases yield, and improves quality. [0003] At present, before coating, it is necessary to manually screen out the empty shells, residues and dust in the seeds, which increases the workload of the staff and reduces the work efficiency. Generally, the coating equipment adopts stirring coating, coating The effect is not good. After coating, it is necessary to wait for the seeds to dry before collecting. The work efficiency is low, the medi...

Problems solved by technology

[0003] At present, before coating, it is necessary to manually screen out the empty shells, residues and dust in the seeds, which increases the workload of the staff and reduces the work efficiency. Generally, the coating equipment adopts stirring coating, coating The effect is not good. After coating, you need to wait for the seeds to dry before collecting. The work efficiency is low, and the medicine cannot be recycled, which wastes a lot of medicine and increases the processing cost.
