Automatic grass discharging passage cleaning mechanism of rear shaft of bottom of mower

Abstract

The invention relates to an automatic grass discharging passage cleaning mechanism of a rear shaft of the bottom of a mower, i.e., a lawn mower which is applied to the lawn pruning of places such as courtyards, parks and road sides. The automatic grass discharging passage cleaning mechanism can be applied to multiple models such as a three-wheeled mower, a series-excited-machine electric mower and a lawn mower, wherein the three-wheeled mower is provided with a grass mowing head, and a front single wheel of the three-wheeled mower is adjusted upwards in a manner that gear engaging is carried out through turning an angle by a flat bar; the series-excited-machine electric mower is provided with a chassis, an anti-collision safeguard and a tape-function wave-disc brake; and the lawn mower comprises an anti-collision safeguard, a tape-function wave-disc brake, a grass blockage poking device and a grass crushing preventer, wherein the anti-collision safeguard is arranged at the front of a chassis of the mower, the tape-function wave-disc brake is arranged at the middle part of the chassis of the mower, and gears of the grass blockage poking device and the grass crushing preventer are driven by an electric motor. The automatic grass discharging passage cleaning mechanism is mounted on the rear shaft of the bottom of the mower. The automatic grass discharging passage cleaning mechanism of the rear shaft of the bottom of the mower comprises grass discharging blades (j1) and direction-changing bevel gears (j2), so that the rotating and direction changing of the grass discharging blades are facilitated.

Description

technical field [0001] The invention relates to a lawn mower used for mowing lawns in courtyards, parks, roads and other places, and a mechanism for automatically cleaning and discharging grass at the rear axle of the bottom of the mower. Wide adaptability, used for the three-wheel lawn mower with the mowing head with the flat rod rotation angle geared to adjust the height of the front single wheel, and the series-excited motor electric lawn mower with the chassis anti-collision safety belt function wave disc brake , including 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, as well as the grass blocker and the grass breaker with the gear driven by the electric motor 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 for...

Problems solved by technology

Anti-collision security and ensure braking. The rear axle at the bottom of the lawn mower automatically clears the grass discharge channel mechanism, which is a long-standing problem. Because the rear axle is reversed, it cannot directly discharge grass.

[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
