Abstract

The invention relates to a weeding robot with the adjustable center of gravity for paddy fields. The weeding robot comprises a hub driving type caterpillar track device, a caterpillar track lifting device, an extension movement device and a slider balance device. The hub driving type caterpillar track device is used for driving a hub through a hub motor, thereby driving caterpillar tracks to run, enabling the robot to walk between rice seedling lines, pressing weeds into mud and even cutting off or pulling out weeds; the caterpillar track lifting device and the extension movement device are used for realizing the lifting and extension of the caterpillar track device so that line changing walking and field ridge crossing walking can be carried out; the slider balance device is matched with the caterpillar track lifting device and the extension movement device and is used for adjusting the center of gravity of the robot and realizing the self balance of the whole body of the robot in the line changing process and the field ridge crossing process and the self-restoring function after the robot sinks into a pit in a paddy field environment with pits; and the weeding robot has the advantages of simple structure, small volume, light weight, convenience in carrying and high universality.

Description

technical field [0001] The invention relates to the technical field of agricultural weeding robots, in particular to a center-of-gravity-adjustable weeding robot for paddy fields. Background technique [0002] At present, farmland weeding methods include manual weeding, chemical weeding, mechanical weeding, etc. Manual weeding and chemical weeding are still the main methods of agricultural weeding at home and abroad. Among them, chemical weeding includes artificial spray weeding and intelligent spray precision weeding. With the advancement of science and technology, more and more attention has been paid to the mechanization and intelligence of weeding devices. At present, the chemical weeding method is popularized, but the herbicide used in this weeding method pollutes the environment, destroys the soil, and even threatens people's health. The weeding robot uses artificial intelligence technology to control relevant institutions to automatically remove weeds in farmland. Th...
