Automatic weeding machine

Abstract

The invention discloses an automatic weeding machine which comprises a clamping rod assembly, a power device, a control mechanism, a bottom plate, a transmission device and a running mechanism, wherein the transmission device comprises a spring, a support, a large belt wheel, a sliding rod, a large bevel gear, a small bevel gear, a transmission belt, a small belt wheel and a cam; the small bevel gear is mounted on a rotating shaft, the large bevel gear and the large belt wheel are mounted on the bottom plate; the small bevel wheel is formed on the back surface of the large bevel gear; the small bevel gear drives the large bevel gear to rotate; the small belt wheel on the back surface of the large bevel gear drives the large belt wheel to rotate through the transmission belt; the upper endsurface of the large belt wheel is integrated with the cam; the fixed support is mounted on the bottom plate on the right side of the cam; the sliding rod passes through a shaft hole of the fixed support and is connected with the clamping rod assembly through a pin shaft at the front end; the power device and the transmission device are mounted on the bottom plate; the power device outputs the rotating shaft of a motive power part of the weeding machine, at the same time, drives the clamping rod assembly to oscillate continuously through the transmission device, and cooperates with the rotating shaft to clamp and remove wormwood.

Description

technical field [0001] The invention relates to an agricultural mechanical device, in particular to an automatic weeder. Background technique [0002] In some farmland or in the fields, some wild plants such as wormwood grow in clusters, with well-developed root systems, and a piece of seed will grow when it hits the ground, which needs to be uprooted. In particular, a wild plant called Solidago canadensis is a vicious weed that mainly grows on river beaches, wasteland, on both sides of roads, beside farmland, and around rural houses. It is a perennial plant with well-developed rhizomes and strong reproductive power. The speed is fast, the growth advantage is obvious, and the ecological adaptability is broad. It competes with the surrounding plants for sunlight and fertilizer until other plants die, thus posing a serious threat to biodiversity. It can be said that there is no grass in the past of the "singularia", so it is called an ecological killer. [0003] These weeds ...

AI Technical Summary

Problems solved by technology

Some Canadian goldenrods grow on both sides of roads, on embankments, around rural houses and on hillsides, and can only be removed manually, but because "Solidago" is a perennial herb with well-developed root system and thick stems , it is very laborious to use manual extraction, and there is an urgent need for an extraction tool that can easily and quickly extract the "solidago" and reduce people's labor intensity
