Lawn mower with grass-pushing anti-blockage device and grass breaking preventer which uses motor to drive gear

Abstract

The invention relates to a lawn mower used for trimming lawns in gardens, parks, and roadsides, and other places. Three wheels are used, and one wheel in an ordinary four-wheel lawn mower is removed, so steering and back-up are more flexible. The three-wheel lawn mower which uses a grass cutting head flat pole to heighten a front single wheel through rotation angle gears is a series excited machine electric lawn mower with a chassis anti-collision protector and a zonal function wave disk brake. The three-wheel lawn mower comprises an anti-collision protector which is arranged on the front part of a mower chassis, a zonal function wave disk brake on the middle part of the lawn mower chassis, and a grass-pushing anti-blockage device and grass breaking preventer which uses motors to drive gears.

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 three-wheel lawn mower with the mowing head and the rotation angle of the flat rod to adjust the height of the front single wheel is a series-excited motor electric lawn mower with a chassis anti-collision safety belt and a function wave disc brake. The anti-collision safety device at the front of the lawn mower chassis, and the lawn mower with a function wave disc brake located in the middle of the lawn mower chassis, as well as a grass blocker and an anti-grass breaker driven by a motor. 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 little more force on the rear upper armrest and have a feeling of leanin...

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.
