Problems solved by technology
[0003] However, the existing liquid fertilizer machinery has a simple structure and cannot flexibly and accurately adjust the amount of liquid fertilizer applied. Too much fertilizer will cause environmental pollution and loss of fertilizer efficiency; too little fertilizer will cause crops to grow poorly

The invention provides a device and a method for measuring dot fertilizer injection accuracy. The device comprises a bed frame, a stepper motor and a fertilizing wheel disc, wherein a driving wheel sleeves a rotating shaft of the stepper motor; a driven wheel sleeves a middle shaft of the fertilizing wheel disc; the driving wheel is connected with the driven wheel through a chain; fertilizing needles are evenly distributed on the side surface of the fertilizing wheel disc; the top of the middle shaft is communicated with a liquid medicine tank through a first conduit; a fertilizer outlet is formed in the lateral wall of the middle shaft; the middle shaft rotates, so that the fertilizer outlet is communicated with the fertilizing needles; an electromagnetic valve is communicated with the first conduit, so that the first conduit is conducted or sealed under the action of the electromagnetic valve; an air compressor pump is communicated with a surge tank; the surge tank is communicated with the liquid medicine tank through a second conduit, and is used for keeping constant air pressure under the action of a pressure regulating valve; the controller is used for controlling the rotating speed of the stepper motor and opening and closing of the electromagnetic valve; and a detection unit is connected with the fertilizing needles, and is used for detecting the flow of the liquid medicine flowing out of each fertilizing needle.
Description
technical field [0001] The invention relates to the testing technology of agricultural machinery, in particular to a device and method for measuring the accuracy of spot fertilizer injection. Background technique [0002] With the reduction of arable land and the rapid growth of population, the role of chemical fertilizers in ensuring food production and economic development has received unprecedented attention. Reasonable use of chemical fertilizers can not only increase food production, but also reduce environmental pollution. [0003] However, the existing liquid fertilizer machinery has a simple structure and cannot flexibly and accurately adjust the amount of liquid fertilizer applied. Too much fertilizer will cause environmental pollution and loss of fertilizer efficiency; too little fertilizer will lead to poor growth of crops. Therefore, in order to effectively control the amount of liquid fertilizer and reduce the loss of fertilizer efficiency, it is urgent to devel...
