Orchard ridge surface obstacle avoiding and weeding device and orchard weeding machine

Abstract

The invention provides an orchard ridge surface obstacle avoiding and weeding device and an orchard weeding machine, and belongs to the technical field of agricultural machinery. The device comprises a movable frame; one end of the moving frame is connected with the obstacle-avoiding weeding mechanism; the obstacle avoiding weeding mechanism comprises a first connecting frame, a second connecting frame and a third connecting frame; the first connecting frame is connected with the moving frame; the second connecting frame is connected with the first connecting frame through a first telescopic piece; the horizontal rotation of the second connecting frame is controlled through the telescopic movement of the first telescopic piece; the third connecting frame is connected with the rotary cutter head; the third connecting frame and the second connecting frame are connected through a first telescopic piece and a second telescopic piece; the swing angle of the rotary cutter head is adjusted through telescopic movement of the first telescopic piece, and the height of the rotary cutter head is controlled through telescopic movement of the second telescopic piece. Through the device, the rotating frame can be controlled to rotate to adjust the transverse breadth of the device, it is guaranteed that the obstacle avoiding weeding mechanism does not make contact with fruit tree trunks on the ridging face to achieve the obstacle avoidance function, and meanwhile the height and the swing angle of the rotary cutter head can be adjusted.

Description

technical field [0001] The disclosure belongs to the technical field of agricultural machinery, and in particular relates to an orchard ridge surface obstacle avoidance weeding device and an orchard weeder. Background technique [0002] Weeding in orchards is an important part of fruit production management. Timely and effective removal of weeds can promote the growth of fruit trees and improve fruit quality. The new type of ridge-type low-stock densely planted orchard, due to the large distance between fruit trees, has sufficient space for weeds to grow, modern water and fertilizer integration technology has increased the content of soil water and fertilizers, and weeds are easy to grow, and the types are complex and the number is large. Chemical weeding will pollute the environment and affect the growth of fruit trees, so weeding operations are changing from chemical weeding to mechanical weeding. Traditional orchard weeding machinery can only remove weeds between rows of...

AI Technical Summary

Problems solved by technology

Traditional orchard weeding machinery can only remove weeds between rows of fruit trees, resulting in the proliferation of weeds between plants and near tree trunks; some machines can avoid obstacles and remove weeds between plants, but the weeding efficiency is low, and the adaptability to ridges is poor. It is too long to be used as a resource, and it is easy to damage young fruit trees

[0003] Patent CN201822050453.1 discloses an obstacle-avoiding mowing head with a protective rubber ring and patent CN201922021936.3 discloses a vertical automatic obstacle-avoiding weeder. The former uses the mowing head to contact the fruit tree and relies on the reaction force to avoid obstacles , b
