Mechanical creepage-type chemical mixing device used for atomizing machine

Abstract

The invention relates to a mechanical creepage-type chemical mixing device used for an atomizing machine, which comprises a plunger pump, wherein the plunger pump is provided with a water inlet and a water outlet, the water inlet is connected with a water container, the water outlet is connected with a spray gun component, and a plunger of the plunger pump is driven by the power of a plunger crankshaft. The mechanical creepage-type chemical mixing device is characterized in that a cam is arranged at the other end of the plunger crankshaft, more than one roller-shaped press roller is embedded in the cam, a housing is mounted outside the press roller, a creepage pipe is arranged between the housing and the press roller, the creepage pipe is compressed on the inner wall of the housing when the press roller rolls, and one end of the creepage pipe is connected with a pesticide mother liquid container and the other end thereof is connected with the water inlet of the plunger pump. According to the technical scheme, the plunger crankshaft and the roller-shaped press roller mounted on the cam are coaxially driven by the same one power force, so that the flow rate of the plunger pump and the flow rate of the creepage pipe are increased or reduced at the same time, which can achieve the effect of dynamically mixing the chemicals at a constant proportion and ensure that the whole atomizing machine can mix the chemicals at an accurate proportion and spray the chemical mixture. The mechanical creepage-type chemical mixing device used for the atomizing machine has significant progresses and positive results.

Description

technical field [0001] The invention relates to a drug mixing device for a sprayer for mixing water and pesticides, in particular to a mechanical peristaltic drug mixing device for a sprayer, which belongs to agricultural plant protection machinery. Background technique [0002] A sprayer (device) is a commonly used agricultural plant protection machine. When the sprayer is used, it mixes a certain proportion of pesticides with water and sprays them out, so there is a process of mixing pesticides and water. The traditional operation is called premixing, which is to mix the pesticide to be sprayed with water in a large container. When working in paddy fields, moving the large container is labor-intensive, and the probability of the operator being exposed to the pesticide is also high. It costs a lot. Therefore, people have developed relevant drug mixing device (drug mixer). [0003] The existing drug mixer mainly comprises a drug mixing device throat with a water inlet and ...

Problems solved by technology

Its disadvantages are: this kind of positive pressure is driven by low pressure, and it is impossible to realize the synchronization between the dosing amount and the speed of the plunger pump, so it is difficult to solve the problem of the mixing ratio of the spray amount at different speeds, and it is impossible to solve the problem of increasing the dosage to high pressure. The problem of spray gun delivering low pressure mixed liquid
