[0002] At present, chemical agents are mostly used to control weeds in agricultural production, but the residual toxicity of chemical agents will cause certain environmental pollution to crops and soil, so in recent years, mechanical weeding methods have begun to receive more and more attention
There are some reports on the control of weeds in the inter-plant area, such as the finger weeding device (Leinonen et al., 2004), the brush weeding device (Kouwenhoven, 1997), but these weeding devices are difficult to effectively control the weeds in the inter-plant area
Osnabrueck University (Osnabrueck Univesity) and Amazone Werke jointly developed the eight-claw cycloidal hoe inter-plant weeding device, but it cannot control the weeds in the 18mm wide area around the crop, and if it is slightly adjusted incorrectly, it will C

Embodiment 1

[0034] Such as Figure 1 to Figure 10 As shown, the present embodiment is an intelligent inter-row mechanical weeder, including a frame, a crop recognition machine vision system, a traverse compensation control system, a depth adjustment system and an inter-row weeding device.

[0035] One end of the frame 2 is fixed with a three-point suspension mechanism 1, and the weeder is connected with the three-point suspension mechanism of the agricultural tractor through the three-point suspension mechanism 1, and the weeder is moved forward by the agricultural tractor. Left and right wheels 5 and right wheels 17 are arranged on the left and right sides of the frame 2 respectively.

[0036] The crop recognition machine vision system includes a camera and an image processor 3. The image processor acquires crop images from the camera, and provides crop information to the lateral movement compensation control system and inter-row weeding device after image processing, and the camera and ...

Abstract

The invention discloses an intelligent inter-row mechanical weeding machine, which comprises a stander, a crop recognizing machine vision system, a sideslip compensation control system, a depth adjusting system and an inter-row weeding device. The intelligent inter-row mechanical weeding machine is towed by a farm tractor to move ahead through the connection between a three-point suspension mechanism on the stander and a three-point suspension mechanism on the farm tractor; the crop recognizing machine vision system is used for collecting row information of crops and position information of each crop; the sideslip compensation control system can adjust the inter-row weeding device to follow the crop rows; the depth adjusting system is used for controlling a depth of a weeding blade tooth in the soil, and profiling land wheels are used for controlling the consistency of the depth of the weeding blade teeth in the soil; and the inter-row weeding device is used for controlling each weeding blade tooth to enter an inter-row area or to get out of the way of the crop. Due to the adoption of the intelligent inter-row mechanical weeding machine, the requirement on the precision of a towing tractor for following the crop rows is low, and the dependence of the inter-row weeding device on the high-precision following of a weeding robot or the towing tractor to the crop rows can be reduced.
