Manual weeding tool with adjustable row width

Abstract

Provided is a manual weeding tool with an adjustable row width. The manual weeding tool is provided with a push pipe, a handle, a support rolling wheel assembly and a cutting tool, wherein the supportrolling wheel assembly is detachably connected to the middle of the pipe body of the push pipe; the operation pitch angle of the cutting tool is manually adjusted by the bottom of the push pipe through an adjusting mechanism, and the bottom of the push pipe is fixedly connected with the cutting tool through the adjusting mechanism; the cutting tool is of a parallelogram hinge connection structurethrough which the weeding operation width of the cutting tool can be manually and adaptively adjusted according to the row width of crops; a locking device for locking the width is cooperatively mounted on the parallelogram hinge connection structure of the cutting tool; cutting edges are formed at the inner ring side of the parallelogram frame of the cutting frame. By adopting the manual weedingtool with the adjustable row width, the operation pitch angle of the cutting tool can be adjusted, and the operation width of the cutting tool can be adjusted according to the row width; the manual weeding tool with the adjustable row width is simple in structure, low in cost, safe during usage, easy to maintain and easier to apply and popularize among peasant households.

Description

technical field [0001] The invention belongs to the technical field of mowing devices, in particular to a manual weeding tool with adjustable row width. Background technique [0002] Along with the raising of horticultural planting level, nowadays, people adopt dense planting, dwarf planting technology scheme in a large number in fruit tree cultivation production. That is, the height of the bottom of the canopy from the ground is extremely small, and the row spacing becomes narrower. This leads to frequent actions such as turning sideways, bending over, extending arms, kicking legs, and turning the body during weeding with a hoe, which is labor-intensive and physically exhausting. Under the existing technology, manual and purely mechanical weeding tools with simple structure, low cost, greener than chemical weeding, environmental protection, no damage to soil structure, safe use, and easy maintenance still occupy the mainstream of the market. Take the invention with the aut...
