Lawn mower with side handle for adjusting fixed brake and unlocking for front three-wheel steering

Abstract

Provided is a lawn mower with a side handle for adjusting a fixed brake and unlocking for front three-wheel steering. The lawn mower achieves remote control over front three wheel steering. The side handle is used for controlling a curved path and a straight path for front wheel steering, and the three-wheel mower can walk straightly; the movement area is larger; when a steering control handle (m1) arranged on a panel does not strain a stay cord and a guide bolt head (s2t) arranged on the head of a guide bolt (s2) enters a shaft pit (s5) formed in a front wheel vertical shaft (t10), a front wheel can be made to walk straightly but not steer; when the steering control handle (m1) arranged on the panel strains the stay cord, the stay cord strains the guide bolt head (s2t) through a guide bolt stay cord hole (s2h), and when the guide bolt head (s2t) arranged on the head of the guide bolt (s2) gets away from the shaft pit (s5) formed in the front wheel vertical shaft (t10), the front wheel is made to walk in the curved path. The guide bolt head (s2t) arranged on the head of the guide bolt (s2) is logarithmic spiral cam meshed with the shaft pit (s5) which has a logarithmic spiral and is formed in the front wheel vertical shaft (t10).

Description

technical field [0001] The invention relates to a lawn mower used for mowing lawns in gardens, parks, roads and other places. It uses three wheels and saves one wheel of a normal four-wheel mower, making turning and reversing more flexible. The lawn mower with suspension wheel height adjustment and panel remote steering control of the front three wheels is a series-excited motor electric lawn mower with a chassis anti-collision safety belt with a function wave disc brake and is included in the front of the lawn mower chassis. The anti-collision safety device, and the wave disc brake with function in the middle of the lawn mower chassis, and the series excitation motor with both mowing head and wire reel including the brake in the middle of the lawn mower chassis Improvements to electric lawn mowers. Background technique [0002] Lawn mowers are widely used to mow grass in the manner chosen by people. When some pedestrians like and are used to using lawn mowers, they put a ...

AI Technical Summary

Problems solved by technology

Anti-collision security and secure braking, mowing and mowing are optional, and there are wires and a large area. These are easier said than done, and they have always been a long-standing problem with electric lawn mowers.

[0007]Why use a cord reel? Because of the long wires scattered on the ground, when the electric lawn mower mows back and forth, sometimes it is accidentally stepped on by feet or crushed by wheels, which affects safety; If the wire is not long enough, mowing is suspended, or the wire is managed manually, which increases safety hazards

Why put a cord reel on an electric lawn mower? Anyone who has used an electric lawn mower knows that weeds often leak when mowing, and they have to be re-mowed. Especially when the environment is complex, such as bushes mixed with the lawn, it is necessary to take several steps forward and several times and repeat the mowing from left to right. Grass; if the reel is placed far away, the wires near the lawn mower cannot be pulled in and out synchronously with the pull and stop in time, or they will fall to the ground limply, and there is a danger of being stepped on or crushed by wheels, or they cannot be pulled in and out in time.
