The invention discloses a dual-flow liquid path variable spray transmission system which comprises a medicine box, a power frequency, a diaphragm pump, a check valve, a quick joint, an ultrasonic wave, a single-chip microcomputer, a stepping motor, a coupler, a nozzle valve needle, a nozzle liquid end, a nozzle main body and a nozzle gas end, and is characterized in that the diaphragm pump is connected to the medicine box; the diaphragm pump is connected to the power frequency; the check valve is connected to the diaphragm pump; the quick joint is connected to the check valve; the nozzle liquid end is connected to the quick joint; the single-chip microcomputer is connected to the ultrasonic wave; the stepping motor is connected to the single-chip microcomputer; the coupler is connected tothe stepping motor; the nozzle valve needle is connected to the coupler; and the nozzle liquid end is connected to the nozzle valve needle. According to the dual-flow liquid path variable spray transmission system, the distance of a leaf curtain layer is detected by the ultrasonic wave, and a distance signal is transmitted to the single-chip microcomputer to control the stepping motor to realize variable-rate spraying, and the system is simple in structure and has a potential application value.
Description
technical field [0001] The invention relates to a double-flow liquid path variable spray transmission system, which belongs to the field of agricultural machinery research. Background technique [0002] In recent years, hydraulic, boom, and wind sprays have become more and more widely produced in modern orchards. The pressure and flow of sprays are different for different crops, as small as 0.3MPa and as large as 400MPa. The machinery is fixed hydraulic spray or increased wind spray, there is no variable spray form, and the general variable spray is aimed at the size of the air supply, or changes the pressure, and there is no effective control for the direct mediation of the liquid flow. [0003] The atomization application mentioned above has great defects. The liquid flow rate during spraying is also a very important factor affecting the atomization effect. The spray volume can be better adjusted by changing the liquid transmission system. Therefore, it is necessary to des...
