Chemical mixing and supplying system of coating machine

Abstract

The invention discloses a chemical mixing and supplying system of a coating machine. The chemical mixing and supplying system of the coating machine comprises a raw material cylinder which is communicated with a mixing cylinder through a first peristaltic pump, and the mixing cylinder is connected to a chemical supplying cylinder through a second peristaltic pump. The chemical mixing and supplying system of the coating machine has the advantages that firstly, labor cost is reduced, simple and reliable operation is achieved, and production efficiency is improved; secondly, matching with high precision is finished, cost is lowered, and waste of components under the condition of artificial matching is avoided; thirdly, the stability and reliability of the system are guaranteed as the system is configured with a film pressure sensor which can monitor the on/off state of circuit in any position of the system; fourthly, the system runs in a totally closed state, so that the environment and the personal safety of workers are protected to a great extent. The whole process is carried out in a fully automatic and totally closed state to prevent toxic gas and powder from entering in air, so that not only is the environment protected, but the personal safety of the workers is guaranteed. The automatic and environment-friendly chemical mixing and supplying system of the coating machine provided by the invention has the beneficial effects of high efficiency, high-precision matching and high percent of pass.

Description

technical field [0001] The invention belongs to the technical field of seed coating equipment, in particular to a drug mixing and supply system for a coating machine. Background technique [0002] Seed coating technology is a plant protection technology widely promoted in my country in the 1990s. It has the characteristics of comprehensive control, low toxicity and high efficiency, saving seeds and medicines, protecting the environment, and high input-output ratio, and is very popular. The current seed coating machine is composed of several parts such as a coating frame, a mixing feeder, and a drug meter. The seeds are adjusted by the counterweight iron outside the feeding hopper on the frame, but the seeds must not overflow the measuring hopper. When the seeds reach the adjusted weight, the metering hopper will turn over automatically and enter the agitator after being buffered by the buffer chamber at the lower part of the frame. Under the action of the agitator, mix the ...

Problems solved by technology

However, these devices cannot achieve fully enclosed operation, and the addition and weighing of seed coating agents require manual operations. Manual operations cannot be completed accurately by the staff alone, and unnecessary waste is caused.

Although the seed coating agent is low in toxicity and high in efficiency, improper use and operation can also cause environmental pollution or personal poisoning accidents
