Description

A combined shear and drum weeder

technical field

The invention relates to the technical field of mower and weeder equipment, in particular to a combined shear and drum weeder. the

Background technique

Lawn mowers are various in the market at present, and lawn mowers are mainly used for trimming and leveling lawn greening equipment, or cutting weeds in field trails, economic forests and cornfields. General lawn mowers can only cut the weeds exposed on the ground, but cannot cut the roots of the weeds left in the land. Because the roots of the weeds are not destroyed, they can still absorb the nutrients in the land and grow quickly again, so that the period for people to mow the grass again is shortened, increasing the amount of labor, and requiring more time and energy. the

Drive the movement of the shearing blade and the cutting mechanism, so as to cut off the weeds on the surface of the land and discharge the weeds from the top of the second baffle to the rear, and then remove the roots of the weeds remaining in the land, and the work is orderly , prevent the cutting mechanism from being entangled by weeds, reduce working resistance, high work efficiency, reduce cost, and strong practicability. the

2. The cutting edge surface of the second blade of the right-angle machete on the cutting mechanism of the drum type combined weeder is made into an arc shape. When weeding, the blade surface of the second blade has a gradual feeding process, reducing Rolling resistance, and in the feed shearing process is a sliding shear, the shearing resistance is small, and the shearing effect is good. the
