Problems solved by technology

Use the multi-legged weeding robot to walk and weed in the rice field to solve the problem that the robots in the prior art cannot adapt to the dense planting environment and damage the rice environment
The weeding robot is based on visual detection technology, bionic hand technology and the design of the webbed structure of the mechanical claws. Through the visual detection technology, the identification and positioning of weeds in the rice field forms the center position of the weed roots, and the mechanical claws are automatically positioned to the weed roots. According to the maturity and type of weeds, different methods of weeding work are selected, which solves the problem that the existing technology cannot identify and locate the weeds at the bottom of rice
The present invention arranges the visual detection component at the bottom of the frame, which has a larger field of view, and solves the problem that the unmanned aerial vehicle in the prior art cannot detect the distribution of weeds under rice with different maturity levels

Abstract

According to the efficient weeding method for the paddy field, a multi-foot weeding robot is used for walking and weeding in the close planting paddy field, a mechanical arm spans two rows of rice, a rack is located above the two rows of rice, the weeding robot does not make contact with the rice in the weeding process, and damage to the paddy field and the rice is reduced. The weeding robot is based on the design of a visual inspection technology, a bionic hand technology and a gripper web-shaped structure, image information of a paddy field is obtained through the visual inspection technology, feature information of weeds in two columns of the paddy field is obtained, the center position of the roots of the weeds is positioned, the types of the weeds are determined, and the roots of the weeds are automatically positioned through a gripper. According to the ripening degree and type of weeds, different modes of weeding work are selected, the weeding modes comprise one or combination of more of root loosening, pulling-out, root breaking or grinding, and the weeding efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of rice weeding, in particular to a high-efficiency weeding method for paddy fields. Background technique [0002] In the process of production, weeds and rice will compete for growth resources, resulting in reduced yields. Therefore, weeding has become the most important link in rice production. In order to reduce the problems of phytotoxicity and environmental pollution of rice, mechanical weeding has gradually replaced chemical weeding. [0003] Existing mechanical weeding generally uses robots, including wheeled, tracked or boat-type structures. Robots with wheeled structure and crawler structure are prone to sag and slip due to their weak grip when walking in paddy fields. The abdomen of the ship-shaped robot is affected by buoyancy. Although the sinking of the robot is effectively improved, the buoyancy of water also reduces the adhesion of the robot to the ground, and the slipping phenomenon is stil...
