Problems solved by technology

[0002] The devices for removing weeds between plants vary greatly, but the improvement of weeding efficiency and the reduction of seedling injury rate are all achieved through a single mechanical aspect or a combination of sensors and machinery
However, some studies rely heavily on the driving device and due to many uncertain factors in the field, resulting in some differences between the actual effect and the computer simulation during operation.

Abstract

The invention relates to an among-plant weeding mechanism with a self-adaption adjustment function. The mechanism is composed of a motor driving unit, a radius-changing seedling avoidance unit and a rotation platform for supporting the radius-changing seedling avoidance unit. The motor driving unit provides power for driving the seedling avoidance unit to rotate, on the basis, a machine vision technology is used for collecting and identifying field seedling information, the seedling avoidance function is achieved through self-adaption adjustment of the seedling avoidance unit, the weeding mechanism helps to improve the among-plant weeding effect, the among-plant weeding efficiency is improved, the damage of weeding to seedlings is reduced, and the crop yield is guaranteed.

Description

Technical field: [0001] The invention belongs to the technical field of agricultural engineering and relates to an inter-row weeding mechanism with self-adaptive adjustment function. Background technique: [0002] Devices for removing weeds between plants vary greatly, but the improvement of weeding efficiency and the reduction of seedling injury rate are all achieved through a single mechanical aspect or a combination of sensors and machinery. However, some studies rely heavily on the driving device and due to many uncertain factors in the field, resulting in some differences between the actual effect and the computer simulation during operation. Therefore, this project is based on the previous basic research on mechanical inter-plant weeding, using computer vision to monitor the operation of the machine, and changing the operating parameters of the machine after processing the obtained image information in real time to achieve more accurate and stable operation. And use t...
