The stirring process can mix the cut weeds and the soil, the weeds can be decomposed by the microorganisms in the soil after being mixed in the soil, so that the abandoned weeds can form nutrient substances which are beneficial to the growth of soybean and corn.

This invention discloses a design method and device for a wheat field weeding actuator based on an operational power consumption model. The weeding actuator includes a rotary blade and a roller, with multiple rotary blades connected to the roller. The initial position is taken as the tip of the rotary blade contacting the soil. The entire weeding process is divided into four working conditions: contacting the soil, cutting the soil, chopping the grass, and lifting the soil. The rotary blade weeding actuator then employs a power consumption model during operation: W = ∑ i 1(W1+W2+W3+W4); The wheat field weeding device mainly consists of a rotary blade, rollers, a drive motor, a controller, and auxiliary mechanisms. The actuator of this invention uses a weeding wheel structure. By analyzing the robot-soil-weed interaction during wheat field weeding, a power consumption model of the rotary blade weeding robot actuator is constructed, and the structural parameters with the lowest power consumption during operation are determined. This not only results in a wide working area, low operating resistance, and high weeding efficiency, but also effectively solves the problem of high seedling damage rate when weeding crops with small row spacing.
