Three-wheel lawn mower having trimmer head and being capable of heightening single front wheel with flat rod to rotate angle changing gears

Abstract

The invention discloses a three-wheel lawn mower having a trimmer head and being capable of heightening a single front wheel with a flat rod to rotate angle changing gears. The lawn mower adopts three wheels, and one wheel of a common four-wheel lawn mower is omitted, so that turning and reversing are more flexible. The three-wheel lawn mower is characterized in that a plurality of angle rotatable changing gears (t7j) are arranged on the wheel carrier (t7); the flat rod (t2) with a handle (t2k) is mounted on the center of a circle, wherein the rotation of the angle rotatable changing gears is based on the center; and a flange (t2j) is arranged on the flat rod (t2), so that the flat rod (t2) with the handle (t2k) can be operated to coordinate with an optional changing gear (t7j) of the angle rotatable changing gears (t7j), and a rollable single front wheel (t1) on the horizontal axis of the front wheel (t4) is heighted with the change of the height between the chassis of the lawn mower and the ground, so that the mowing height can be changed.

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 wave disc brake with function in the middle part of the lawn mower chassis, and the mowing head and winding line with the brake in the middle part of the lawn mower chassis Series Motor Electric Lawn Mower. 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 rea...

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.
