Description

A forest garden weeding machine

Technical Field

The invention relates to the technical field of agricultural and forestry machinery, in particular to a forest garden inter-row weeding machine.

Background Art

Weeding is a heavy task in the management of forests, orchards, etc. Weed clearing is essential for promoting the growth of trees and increasing the benefits and yields of various types of forests. Generally, repeated weeding is required before trees sprout, after summer felling, and before weeds set seeds in autumn. The current weeding methods are mainly manual weeding, chemical weeding, and mechanical weeding. Manual weeding is inefficient, labor-intensive, and faces the problem of no one available. Although chemical weeding can strongly eliminate weeds, it is easy to affect tree growth and leaf quality. Long-term use accumulates soil pesticide residues and pollutes the soil environment. Mechanical weeding uses hoeing, raking, and turning to kill weeds and turn out grass roots. At the same time, it loosens the soil, which is conducive to water storage and moisture conservation. It is an organic combination of agronomy and agricultural machinery technology. The efficiency of mechanical weeding is 4 to 10 times that of manual weeding, and the cost of using mechanical weeding is less than half of the labor cost of manual weeding. It is an important measure to improve the efficiency of forest management.

In the prior art, an invention patent entitled "An Intelligent Inter-row Mechanical Weeder" with announcement number CN102612874 B and announcement date 2013.12.25 is disclosed, which includes a frame, a crop recognition machine vision system, a lateral compensation parallel mechanism, a depth adjustment mechanism and an inter-row weeding device. The weeder is connected to the three-point suspension mechanism of the agricultural tractor through a three-point suspension mechanism on the frame and is pulled forward by the tractor. The left and right sides of the frame are respectively provided with left and right wheels. The crop recognition machine vision system is fixedly connected to the frame, the lateral compensation parallel mechanism is installed at the other end of the frame, the depth adjustment mechanism is connected to the lateral compensation parallel mechanism, the inter-row weeding device includes an inter-row weeding mechanism and weeding claws, and the inter-row weeding mechanism bracket and liquid The pressure motor mounting base is fixed to the rear end of the depth adjustment mechanism, and the inter-row weeding mechanism bracket is installed with an inter-row weeding mechanism. When working, the crop recognition machine vision system identifies the crop and extracts the crop position information. The inter-row weeding device controls each weeding claw to enter the inter-row area or avoid the crop according to the crop position, weeder position, forward speed and rotation speed of the weeding claw. Although it can remove weeds between crop rows and plants in farmland, when it is used to clean weeds between several trees in a forest garden, it can also be used to remove weeds between two adjacent rows of trees, but it cannot be used to remove weeds between two adjacent trees in the same row of trees.
