Automatic variable rate fertilization device based on stepping motor and control method of automatic variable rate fertilization device

Abstract

The invention discloses an automatic variable rate fertilization device based on a stepping motor and a control method of the automatic variable rate fertilization device. The automatic variable rate fertilization device comprises a traction device, a material box and a discharge adjusting device, wherein the discharge adjusting device is provided with N fertilizer discharging holes; the upper end of each fertilizer discharging hole is communicated with the material box through a fertilizer guiding pipe; the lower end of each fertilizer discharging hole is connected with a fertilizing pipe; an adjusting plate is further inserted into the discharge adjusting device; the adjusting plate is provided with N material passing holes adapted to the N fertilizer discharging holes; the adjusting plate is engaged with a gear on a rotary shaft of the stepping motor through a rack on one side; the adjusting plate is driven by the stepping motor to move left and right to change the apertures of the fertilizer discharging holes so as to realize variable rate fertilization. The automatic variable rate fertilization device has the obvious effects that the structure is simple; the stepping motor is controlled in real time according to fertilizing information of each land to adjust the fertilizing amount of the automatic variable rate fertilization device; the utilization rate of fertilizer is improved, the influences on an ecological environment are reduced and the popularization cost is low.

Description

technical field [0001] The invention relates to the technical field of automatic control of agricultural machinery, in particular to an automatic variable fertilization device based on a stepping motor and a control method thereof. Background technique [0002] In our country, agriculture has always been the foundation of national economy, national self-reliance and social stability. People's vital interests and social stability are always affected by agricultural development. [0003] At present, my country's traditional agriculture has problems such as unreasonable use of chemical fertilizers, causing a lot of environmental pollution, and low fertilizer utilization rates. Therefore, the implementation of variable fertilization on demand can greatly improve the utilization rate of chemical fertilizers, reduce the waste of chemical fertilizers and reduce the adverse effects of chemical fertilizers on the environment, and the economic, social and ecological benefits have been...
