Intelligent inter-row mechanical weeding machine

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.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an intelligent row-to-row mechanical weeder. Background technique [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 .

Problems solved by technology

[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 Causes damage to crops, and is greatly affected by the soil, and cannot avoid damage to crops by large soil clods (Dedousis, 2007)

The UK developed the notched disc hoe (Tillett et al., 2008), Denmark developed the rotary tooth weeding device (Griepentrog, 2006), the rotary disc rake tooth weeding device (Lempens et al., 1996) and the eight-claw strain Weeding devices (Zhang Pengju. et al., 2010), but they all need to be installed on a traction platform with navigation function or on an intelligent robot to realize the mechanical weeding function, and the price is relatively expensive

At present, there is still little research on intelligent inter-row mechanical weeding machinery that does not rely on agricultural robots and can be pulled by a tractor manipulated by the driver, let alone mature inter-row weeding machinery.
