Automatic orchard obstacle-avoiding mowing machine

Abstract

The invention relates to an automatic orchard obstacle-avoiding mowing machine. The automatic orchard obstacle-avoiding mowing machine comprises a primary machine frame, and a secondary machine frameis rotationally arranged in the primary machine frame; the automatic orchard obstacle-avoiding mowing machine also comprises a first hollow rod and an elastic supporting rod, one end of the secondarymachine frame is hinged to one end of the first hollow rod, and the other end of the secondary machine frame is hinged to one end of the elastic supporting rod; a second hollow rod is perpendicularlyand fixedly connected to the other end of the first hollow rod, a cutter disc shaft arranged in the axial direction of the second hollow rod is arranged in the second hollow rod, and is sleeved with an obstacle avoiding wheel, and a cutter disc is fixedly connected on the cutter disc shaft; the other end of the elastic supporting rod is hinged to the side wall of the first hollow rod; the automatic orchard obstacle-avoiding mowing machine also comprises a driving device, and the driving device is arranged on the firs hollow rod. By means of the automatic orchard obstacle-avoiding mowing machine, fruit-tree inter-row weeding and inter-plant weeding operation can be carried out at a time; fruit trees can be automatically avoided during weeding, weeds close to roots of fruit trees are weeded;the structure is simple, and the theory is novel.

Description

technical field [0001] The invention belongs to the technical field of agricultural plant protection tools, and relates to an automatic obstacle avoidance lawnmower for orchards. Background technique [0002] In the orchard, fruit trees are planted according to a certain row spacing and plant spacing. The row spacing and plant spacing of fruit trees are relatively large, so that more weeds grow on the land between the rows and plants of fruit trees, and the weeds in the orchard will absorb the nutrients in the orchard soil, affecting the growth of fruit trees and the yield of fruit trees. The weeds in the orchard need to be removed many times before the fruit trees are harvested. [0003] The area of ​​the orchard is large, and the cost of weeding only by manpower is relatively high, so weeds need to be removed with the help of weeding machinery. The row spacing of fruit trees is generally larger than the tree spacing, and weeding operations can be carried out directly by ...

AI Technical Summary

Problems solved by technology

The distance between rows of fruit trees is generally larger than the distance between trees. Weeding operations can be carried out directly with mowers, but weeds between fruit trees cannot be removed mechanized with a lawn mower.

In the process of weeding with weeding machinery, if the weeding machine is too close to the root of the fruit tree, it will easily cause damage to the root of the tree, and a safe space between the weeding machine and the root of the fruit tree will make it difficult to remove the weeds around the root of the fruit tree. less than comprehensive weed control effect

In addition, most of the existing large-scale weeding machines are fixed-range, with fixed paths during work, poor adaptability to special occasions such as rows of plants, unsatisfactory weeding operations, and cannot remove weeds between the plants.

In addition, the current obstacle avoidance lawn mowers on the market have complex obstacle avoidance designs. Obstacle recognition is based on ultrasonic or infrared, and hydraulic or electric systems perform obstacle avoidance actions. The principle is complicated, which reduces the reliability of the lawn mower. In the process of weeding in orchards, the weeding machines available on the market can only weed between rows with large spacing, and pay little attention to the spacing of fruit trees
