Problems solved by technology

There is no limit mechanism for the height-adjusting tooth plate of the existing lawn mower, that is, when the user adjusts the height of the mowing blade or when the gear is accidentally disengaged due to vibration during use, the adjustment handle may run out of the regulation of the lawn mower. The actual mowing height falls below the minimum mowing height specified by the lawn mower, causing the blade to be too close to the ground, causing safety hazards to users, and having adverse effects on the lawn and the mower itself.

Embodiment Construction

[0010] Such as figure 1 A height-adjusting tooth plate limit device for a lawn mower is shown, including a height-adjusting tooth plate 2, and more than two sawtooth 1 is arranged on the outer periphery of the height-adjusting tooth plate 2, and the sawtooth 1 is connected with an adjustment handle 3, and the height-adjusting tooth plate 2 The outer side is connected with a coaxial lawnmower rear wheel 5; the height-adjusting tooth plate 2 has more than two saw teeth 1 on the outer periphery, and the two saw teeth at the left and right ends are provided with an axial extension 4, and the extension 4 The axial spacing with the lawn mower rear wheel is less than the diameter of the adjustment handle 3 .

[0011] As structure preferably heightening tooth plate 2 periphery except two sawtooth 1 at left and right ends, the axial distance between other sawtooth and lawnmower trailing wheel is greater than adjustment handle 3 diameters. The diameter of the adjustment handle 3 is 10m...

Abstract

The invention discloses a heightened gear plate limiting device for a hay mower. The heightened gear plate limiting device comprises a heightened gear plate, two or more saw teeth are arranged on the periphery of the heightened gear plate, the saw teeth are in matched connection with an adjusting handle, and the outer side face of the heightened gear plate is connected with coaxial hay mower rear wheels; the saw teeth are arranged on the periphery of the heightened gear plate, axial extending segments are arranged on the two saw teeth at the left end and the right end, and the axial distance between the extending segments and the hay mower rear wheels is smaller than the diameter of the adjusting handle. Through the extending segment structures at the left end and the right end, on the basis of not additionally increasing the limiting, the axial distance between the extending segments and the hay mower rear wheels is reduced, and therefore the adjusting handle cannot be separated from the device, the stroke of the adjusting handle is limited, and the peril incidents caused by grounding of blades controlled by the heightened gear plate are prevented.

Description

technical field [0001] The invention relates to an adjusting device for a lawn mower blade, in particular to a height-adjusting tooth plate limiting device for a lawn mower. Background technique [0002] At present, the distance between the lawnmower blade and the lawn on the ground is determined by the adjusting handle matched by the heightening tooth plate. Specifically, the distance between the blade and the lawn on the ground is finally determined by adjusting the handle and adjusting the sawtooth at different positions on the outer periphery of the tooth plate. There is no limit mechanism for the height-adjusting tooth plate of the existing lawn mower, that is, when the user adjusts the height of the mowing blade or when the gear is accidentally disengaged due to vibration during use, the adjustment handle may run out of the regulation of the lawn mower. The actual mowing height falls below the minimum mowing height specified by the lawn mower, causing the blade to be ...
