Double-flow type liquid way variable transmission system

Abstract

The invention discloses a double-flow liquid path variable transmission system, including a power supply, a single-chip microcomputer, a radar, a one-way valve, a liquid pressure gauge, a liquid flow meter, valve one, valve two, a nozzle liquid end, a medicine box, a liquid pump, and a nozzle body , Nozzle air end. It is characterized in that: the liquid pump is connected to the medicine box, the one-way valve is connected to the liquid pump, the liquid pressure gauge is connected to the one-way valve, the liquid flow meter is connected to the liquid pressure gauge, the valve one and The second valve is connected in parallel and connected to the liquid flow meter and the liquid end of the nozzle respectively. The liquid end of the nozzle, the main body of the nozzle and the gas end of the nozzle together form a double-flow nozzle. The radar is connected to a single-chip microcomputer, and the single-chip microcomputer controls the liquid pump through a power supply. The invention provides power through a liquid pump to meet the liquid flow required for normal spraying, and the invention has a simple structure, and the addition of parallel valves can reduce the liquid pressure, which has far-reaching research value.

Description

technical field [0001] The invention relates to a double-flow liquid path variable transmission system, which belongs to the field of plant protection machinery research. Background technique [0002] At present, there are various forms of nozzles, including low-pressure nozzles, high-pressure nozzles, ultra-high-pressure nozzles, and cavitation nozzles, all of which are based on the input pressure of the liquid system. Power spray, plus air blowing, but the hydraulic transmission system is all in a fixed form, and there is no variable adjustment device in the transmission system. For the air atomization nozzle, the reasonable layout of the hydraulic transmission system must be ensured. [0003] In addition to the traditional liquid circuit system, the above-mentioned nozzles also involve the air circuit system. For this reason, it is necessary to ensure that the appropriate liquid circuit transmission system becomes the key factor for atomization. For this reason, it is nec...
