Transitional hob structure of a lawn mower

Abstract

The invention provides a transitional type hobbing cutter structure of a field mower, and belongs to the technical field of garden equipment. The problems that existing hobbing cutter structure gets stuck easily in a working process, and the like are solved. The transitional type hobbing cutter structure of the field mower disclosed by the invention comprises a hobbing cutter shaft, at least two cutter rests and a plurality of hobbing cutter blades, wherein the hobbing cutter shaft passes through the cutter rests in sequence and is fixedly connected the cutter rests; the hobbing cutter blades are arranged at the outer edge of each cutter rest in a spiral manner; a transitional ring is fixedly arranged on the hobbing cutter blades; the projection, of the transitional ring, along the axial direction of the hobbing cutter shaft and the projection, of the hobbing cutter blades, along the axial direction of the hobbing cutter shaft are both annular shaped; the two kinds of projections are homocentric, and the semidiameters of the outer edges of the projections are identical. The transitional type hobbing cutter structure of the field mower disclosed by the invention has the advantage that hobbing cutters can continuously work without pause during a rolling process through arranging the transitional ring.

Description

technical field [0001] The invention belongs to the technical field of garden equipment, and in particular relates to a transitional hob structure of a lawnmower. Background technique [0002] With the development of society and economy, people's environmental awareness is getting stronger and stronger, and a large number of lawns and grasslands have entered our lives, so lawn mowers have also been widely used. The cutting mechanism of the lawn mower mainly includes a rotating hob and a fixed knife, the hob rolls up the grass, and the fixed knife cuts the weeds. [0003] Since the blade will be worn after a period of use, the blade gap between the fixed knife and the hob will increase. If the gap is too large, the mowing effect will be unsatisfactory. Therefore, a gap adjustment mechanism is generally installed on the fixed knife, such as using a spring. The fixed knife is tightly pulled against the hob, but due to the wear of the blade edge, there will be ups and downs bet...

AI Technical Summary

Problems solved by technology

[0003] Since the blade will be worn after a period of use, the blade gap between the fixed knife and the hob will increase. If the gap is too large, the mowing effect will be unsatisfactory. Therefore, a gap adjustment mechanism is generally installed on the fixed knife, such as using a spring The fixed knife is tightly pulled against the hob, but due to the wear of the blade edge, there will be ups and downs in the fit between the fixed blade and the hob blade, and because the fixed knife is pulled tightly by the spring, when the fixed blade is It is easy to get stuck when transitioning between two adjacent hob blades
