Synchronous injection-type medicine mixer for spraying machine

Abstract

A synchronous injection-type medicine mixer for a spraying machine comprises am engine. The engine drives a spray pump. The spray pump is provided with a water suction port and a water outlet. The water suction port is connected with a water suction component. The water outlet is connected with a spray pipe and a spray gun. The water suction component comprises a water suction pipe. The synchronous injection-type medicine mixer for the spraying machine is characterized in that: a mixing pipe is connected in the water suction pipe; the mixing pipe comprises a water inlet, a suction chamber, a mixing chamber and a liquid outlet; a jet flow nozzle with a conical inner bore is arranged in the water inlet; the opening of the jet flow nozzle is positioned in the suction chamber; a medicine suction port is formed in the wall of the mixing pipe in the suction chamber; a miniature electromagnetic injection pump is driven by the engine and a synchronous signal; pesticides in a mother solution container are sucked by a solution suction port of the electromagnetic injection pump; and a medicine outlet of the electromagnetic injection pump is connected with the medicine suction port of the mixing pipe.

Description

technical field [0001] The invention relates to a drug mixer for mixing water and pesticides for a sprayer, in particular to a synchronous injection type drug mixer for a sprayer, which belongs to agricultural plant protection machinery. Background technique [0002] The sprayer 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 most common traditional operation is pre-mixed spraying, 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 operator is exposed to pesticides. The probability is also high, and it needs to be operated by a special person, and the labor cost is high. Therefore, people have developed relevant drug mixers, such as Chinese patent ZL00267051.8, which is called "positive pressure dr...

AI Technical Summary

Problems solved by technology

The positive pressure drug mixer of this patent is a kind of water mixing drug, but it failed to explain the specific product structure of the positive pressure drug addition. The speed of the engine is synchronized, so it is difficult to solve the problem of the mixing ratio of the spray volume at different speeds

Another example is Chinese Patent No. ZL200820043764.9, which is named "Pipeline Mixer". This patented technology uses the pressure difference between the inlet and outlet and the force of the spring to control the output of the liquid medicine. Not only the structure is complicated, but also the reliability is affected. many factors
