Gas-liquid double flow type variable transmission system

Abstract

The invention discloses an air-liquid double-flow variable transmission system, which comprises three parts: an air transmission system, a liquid transmission system and a detection system. It is characterized in that: the air transmission system includes the output shaft of the tiller, an air pump, an air source processor, a pressure sensor, a U/P valve, and an air end connector; the liquid transmission system includes a medicine box, a liquid pump, a direct current Power supply, one-way valve, flow sensor, proportional valve, liquid end joint, nozzle, the detection system includes a laser rangefinder and a single-chip microcomputer, the air pump is connected to the output shaft of the tiller, and the DC power supply is connected to the liquid pump, The laser rangefinder is connected to the single-chip microcomputer, one end of the spray head is connected to the gas end joint, and the other end of the spray head is connected to the liquid end joint. The invention is connected with the micro tillage machine, and all components are installed on the micro tillage machine, so that mobile spraying can be realized, and variable spraying can be realized through the pressure of the gas path and the flow rate of the liquid path, and the structure of the present invention is clear and has strong research value .

Description

technical field [0001] The invention relates to a gas-liquid double-flow variable transmission system, which belongs to the research field of orchard spraying machinery. Background technique [0002] At present, there are various forms of orchard spraying machinery, such as air-driven spray, hydraulic spray, spray gun spray, etc., but these are variable sprays with a single factor, and variable sprays can be realized by changing the spray pressure and fan speed alone. , and there is no target detection substance, which has certain limitations for achieving high-efficiency and precise spraying. [0003] The above-mentioned variable spraying has the following deficiencies and disadvantages: the spraying form adopts large spray volume and rain spray, which cannot make rational and effective use of pesticides, resulting in waste of chemical liquid, polluting the environment, and it is difficult to achieve high-efficiency spraying operations. Contents of the invention [0004]...
