Description

Technical Field

[0001] The invention relates to the technical field of weeders, in particular to an intelligent weeder. Background Art

[0002] A lawn mower is also called a lawn mower, a lawn mower, or a lawn trimmer. A lawn mower is a mechanical tool used to trim lawns, vegetation, etc. However, a lawn mower is mainly composed of a cutter disc, an engine, a running wheel, a running mechanism, a blade, an armrest, and a control part. It is a tool that plays an important role in agricultural production.

[0003] For example, the patent number CN217241457U discloses a tree planting and weeding device, which has a screw locking fixing box and a connecting block, and can conveniently remove the mowing blade for cleaning and maintenance, thereby preventing the mowing blade from bending and external corrosion that causes a decrease in the service life of the blade. At the same time, the scraper plate inside the positioning frame can block the grass on the surface of the mowing blade, and the inclined surface of the mowing blade can reduce the probability of grass being pushed away from the mowing blade, thereby ensuring mowing efficiency.

[0004] However, although the existing weeding devices can facilitate the treatment of weeds, when dealing with weeds between trees, it is easy for the weeding devices to be inconvenient to perform weeding operations due to the narrow spacing between the trees. Workers are required to frequently move the weeding devices to treat the weeds between the trees, which is not only troublesome to operate, but also greatly reduces the weeding efficiency. Summary of the invention
