High-ground-clearance-boom-sprayer water returning pipe system

Abstract

The invention relates to a high-ground-clearance-boom-sprayer water returning pipe system. The high-ground-clearance-boom-sprayer water returning pipe system mainly comprises a main pesticide chest, an auxiliary pesticide chest, a feeding pesticide chest, a three-way valve, a five-way valve, a primary filter, a secondary filter, a jet filter A, a jet filter B, a main pesticide pump, a jet pump A, a jet pump B, electromagnetic valve sets, spraying rods, spraying heads, a flow meter, a control line, a pressure adjusting device, a flow adjusting device, a tee joint and related pipes. The auxiliary pesticide chest is communicated with the main pesticide chest through an auxiliary-pesticide-chest jet liquid discharging pipe, the jet filter A, a jet connecting pipe A, the jet pump A and a main-pesticide-chest jet pipe in sequence; the main pesticide chest is communicated with the auxiliary pesticide chest through a main-pesticide-chest jet liquid discharging pipe, the jet filter B, a jet connecting pipe B, the jet pump B and an auxiliary-pesticide-chest jet pipe in sequence. The high-ground-clearance-boom-sprayer water returning pipe system has the functions that water is automatically added into the pesticide chests on the two sides through the main pesticide pump, pesticide is automatically mixed, water returning jet stirring is carried out, pesticide liquid of the pesticide chests on the two sides is balanced, and pesticide is accurately sprayed; the labor strength can be effectively reduced, the spraying quality is improved, and the pesticide applying effect is guaranteed.

Description

[0001] (1) Technical field [0002] The invention relates to a return water pipeline system of a spray boom sprayer with high ground clearance, which belongs to the field of plant protection machinery. [0003] (2) Background technology [0004] With the acceleration of rural land transfer and large-scale agricultural operation, large boom sprayers as plant protection machinery have been widely used. Among them, the high-gap boom sprayer is used for the prevention and control of diseases and insect pests in the middle and late stages of high-stalk crops (such as cotton, corn, sugarcane, sorghum, etc.), and has a good effect in reducing labor intensity and improving operation quality. But for the high ground clearance sprayer with split medicine box, there are the following problems: (1) because there are two left and right medicine boxes, a single medicine pump cannot meet the requirements of liquid medicine supply and return water of each pipeline, especially not real-time Ba...

Problems solved by technology

But for the high ground clearance sprayer with split medicine box, there are the following problems: (1) because there are two left and right medicine boxes, a single medicine pump cannot meet the requirements of liquid medicine supply and return water of each pipeline, especially not real-time Balance the liquid medicine in the medicine box and stir the return water, resulting in uneven distribution of the medicine liquid in the medicine box on both sides and insufficient mixing of the medicine solution, resulting in poor spray quality and affecting the control effect; (2) There is no separate water supply for the medicine box on both sides device, when there is no faucet in the field, you can only rely on manual watering, the larger the capacity of the medicine box, the greater the labor intensity
