Problems solved by technology

[0003] Because the blade will be worn after a period of use, the blade gap between the fixed knife and the hob will increase, but if the gap is too large, the mowing effect will be unsatisfactory. Therefore, a gap adjustment mechanism is generally installed on the fixed knife. The fixed knife is tightly

Embodiment Construction

[0023] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0024] Such as figure 1 As shown, the cutting mechanism of a kind of lawnmower provided by the present invention comprises frame 1, fixed knife, hob and the drive mechanism that drives hob to roll, and fixed knife and hob are all arranged on frame 1, and hob The weeds are rolled in, and the blades of the fixed knife and the hob are attached to form a cutting edge, and the weeds are cut in cooperation with the hob during the rolling process. In order to make the fixed knife and the hob automatically adjust the blade gap after the blade is worn, an automatic knife adjustment mechanism for the fixed knife is provided on both sides of the frame 1, and the automatic knife adjustment mechanism can keep the fixed knife against th...

Abstract

The invention provides a mower cutting mechanism, belongs to the garden equipment technical field, and solves the problems in the prior art that an existing mower can easily have blocking problems when a blade is worn; the mower cutting mechanism comprises a machine frame, a fixed cutter, a hobbing cutter and a drive mechanism driving the hobbing cutter to roll; the hobbing cutter comprises a hobbing cutter shaft, tool rests, and a plurality of hobbing blades; the hobbing blade is fixedly provided with a transition ring; the projection of the transition rings along the hobbing cutter shaft axial direction and the projection of the hobbing blades along the hobbing cutter shaft axial direction are respectively in an annular shape, wherein the two projections are concentric and peripheral semidiameters of both are same; the fixed cutter is arranged on the machine frame, can automatically approach to the hobbing cutter through an automatic toolsetting mechanism, and can attach to the blade portion of the hobbing cutter so as to form a shearing edge. The automatic toolsetting mechanism is compact and reasonable in structure, can automatically adjust blade gaps, and the hobbing cutter can contentiously work with no blocking in working process.

Description

technical field [0001] The invention belongs to the technical field of garden equipment, in particular to a cutting mechanism of a mower. 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] Because the blade will be worn after a period of use, the blade gap between the fixed knife and the hob will increase, but if the gap is too large, the mowing effect will be unsatisfactory. Therefore, a gap adjustment mechanism is generally installed on the fixed knife. The fixed knife is tightly pulled by the spring against the hob, but due to the wear of the blade edge, the joint between the fixed blade and the hob will have ups ...
