Weeding and obstacle avoiding mechanism and weeding and obstacle avoiding robot

Abstract

The invention relates to a weeding and obstacle avoiding mechanism and a weeding and obstacle avoiding robot. The weeding and obstacle avoiding mechanism comprises a weeding structure and an obstacleavoiding structure, wherein the weeding structure comprises a fixed cutter disc cover and a rotating cutter disc cover; the rotating cutter disc cover is connected with the fixed cutter disc cover through the obstacle avoiding structure; the obstacle avoiding structure comprises a connecting rod and a linear driving part; the first end of the connecting rod is rotatably connected with the fixed cutter disc cover, and the second end of the connecting rod is connected with the rotating cutter disc cover; and the first end of the linear driving part is rotatably connected with the fixed cutter disc cover, and the second end of the linear driving part is rotatably connected with the connecting rod. According to the weeding and obstacle avoiding mechanism and the weeding and obstacle avoiding robot, the obstacle avoiding structure is adopted to drive the rotating cutter disc cover to rotate relative to the fixed cutter disc cover, obstacle avoiding and mowing between plants can be achieved,damage to fruit trees is prevented, and weeds around the fruit trees at different intervals can be removed thoroughly; the weeding width can be changed; and the mowing operation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a weeding and obstacle avoidance mechanism and a weed and obstacle avoidance robot. Background technique [0002] The orchard industry is an important industry in my country, and the fruit trees in the orchard are planted according to a certain row spacing and plant spacing. Because the distance between the fruit trees is relatively large, many weeds will grow between the fruit trees, and the weeds will absorb the nutrients in the soil, affecting the growth and yield of the fruit trees. Therefore, it is necessary to remove the weeds in the orchard many times. [0003] With the continuous improvement of the mechanization level of orchards, various types of weeding machines have emerged at home and abroad, but the level of intelligence of orchard weeding machines is low, the number of dedicated advanced weeding machines is small, the content of weeding technology is ...

AI Technical Summary

Problems solved by technology

[0003] With the continuous improvement of the mechanization level of orchards, various types of weeding machines have emerged at home and abroad, but the level of intelligence of orchard weeding machines is low, the number of dedicated advanced weeding machines is small, the content of weeding technology is low, the operating area is small, and the price is expensive.

Most orchard weeders work in the way of walking between rows, which makes it impossible to effectively remove the weeds between the fruit trees, especially the weeds around the fruit trees. Most of the equipment that can achieve weeding between the orchards is a backpack type Weeder, oblique weeder, hand-push weeder and rear-pull hanging weeder, this type of weeder has low working efficiency, poor passability, large labor consumption, low weeding rate, and great damage to fruit trees. of weeds still need manual removal

These all limit the development of orchard mechanization level, and also affect the orchard output
