Abstract

The invention discloses an adjustable-flow proportion fertigation device. The adjustable-flow proportion fertigation device comprises a motor, a pump, a water inlet tube, a water outlet tube, an adjustment device and an operation module, wherein the adjustment device comprises a motor drive module, a singlechip, an input module and a display module; a development board button comprises a power supply switch, a flow button, a running button and a stopping button; the water inlet tube and the water outlet tube are connected with the pump, the pump is electrically connected with the motor, and the motor is connected with the adjustment device; by programming the single chip, the duty cycle is controlled and the PWM voltage output by the motor drive module is reduced, thus achieving the effect of adjusting the flow of the motor. The device is simple to operate and uniform in fertigation, and combines drop irrigation with fertigation, thus realizing fertigation precision.

Description

technical field [0001] The invention belongs to the field of fertilization equipment, in particular to a proportional fertilization device with adjustable flow rate. Background technique [0002] With the continuous expansion of the planting area using drip irrigation technology in agricultural production in our country, precision fertilization has attracted more and more attention. For areas that have adopted drip irrigation technology in a large area, it is completely possible to use existing drip irrigation resources to integrate precision agriculture. The combination of drip irrigation and fertilization technology realizes precise fertilization. Thereby improving the utilization rate of fertilizers, promoting crop yields, reducing field labor and pollution to soil and groundwater. [0003] Fertilization methods commonly used in drip irrigation systems at home and abroad include hydraulically driven proportional fertilization pumps, differential pressure fertilization ta...
