A double-touch rod positioning type three-degree-of-freedom corn interplant weeder

Abstract

The invention provides a double-contact rod positioning type three-degree-of-freedom corn interplant weeder, which includes a walking wheel, a frame, a power supply box, a control box, a combined double-contact rod positioning unit, a sliding rail obstacle avoidance unit and a weeding unit. The wheel is the walking mechanism; the frame is the installation carrier of other mechanisms; the power supply box provides power for the weeder; the control box is the control unit of the weeder, which receives and processes information in real time and sends control commands to control the relative movement of the slide rail obstacle avoidance unit to drive the The weeding unit is used for precise obstacle avoidance and weeding; the combined double-touch rod positioning unit is used to locate two adjacent plants in the corn row, and according to the corn position information, the sliding rail obstacle avoidance unit is controlled in the direction of the machine and the vertical direction of the machine. The displacement of two degrees of freedom Compensation to determine the precise obstacle avoidance trajectory at a fixed point; the weeding unit is fixedly connected with the sliding rail obstacle avoidance unit, including the weeding knife. The weeding knife moves horizontally and rotates vertically under the driving of the sliding rail obstacle avoidance unit, so as to realize the obstacle avoidance along the track for weeding.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a double-touch rod positioning type three-degree-of-freedom corn interplant weeder. Background technique [0002] According to the tradition of intensive farming and meticulous farming in my country, weeding is an important part of it. Weeds grow between the rows and plants of crops and compete with crops for water, nutrients and sunlight. If they are not controlled, they will seriously affect the yield and quality of crops. At present, weeding techniques in agricultural production mainly include chemical weeding and non-chemical weeding. Among them, spraying herbicides is the most widely used, but excessive use of herbicides will pollute the surrounding environment and destroy the ecological balance. In recent years, with the promotion of the concept of green development and the promotion of organic planting models by the state, mechanical weeding has received muc...

Problems solved by technology

However, the touch rods in the above two devices touch the corn stalk stubble from time to time. For a single corn stubble, only a single touch rod is in contact with it, so it is impossible to locate the corn stubble

For single-row crops, there are few researches on the detection form of the probe installed between the crops
