AI Technical Summary

Technical Problem

Existing manual handheld weeding tools are prone to damaging the roots of broad beans in broad bean fields, and are not flexible in operation, making it difficult to accurately control the weeding range, which affects crop growth and planting efficiency.

Method used

A weeding device for broad bean fields designed to prevent root damage is used. It adopts symmetrically arranged hemispherical clamping blocks, anti-slip pads and anti-slip teeth, combined with the linkage of inclined wedge mechanism and pull rod. The opening and closing of the clamping blocks can be controlled by one hand through U-shaped operating frame, avoiding direct contact with soil and damage to roots and achieving precise weeding.

Benefits of technology

It improved weeding efficiency, protected the root system of broad beans, enhanced operational stability and comfort, simplified the operation process, and increased operational flexibility in complex terrain.

Abstract

The utility model relates to the technical field of agricultural mechanical equipment, in particular to broad bean field weeding equipment capable of preventing root injury, which comprises a mounting plate and two hemispherical clamping blocks symmetrically mounted on the mounting plate, and protective pads are mounted on the outer walls of the clamping blocks. The outer walls, close to the opposite sides, of the two clamping blocks are each fixedly connected with an anti-skid pad, and the outer walls of the anti-skid pads are provided with horizontally-arranged anti-skid teeth. The semi-spherical clamping blocks which are symmetrically arranged are matched with the non-slip mats and the non-slip teeth, so that weed stalks can be stably clamped during weeding, and roots are prevented from being damaged due to direct contact with soil; by means of the linkage design of the wedge mechanism and the pull rod, an operator can control opening and closing of the clamping blocks through the U-shaped operation frame with one hand, precise weeding is achieved, and the working efficiency and the broad bean root system protection effect are greatly improved.
