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?

Embodiment Construction

[0111] Build the computer 3D model first, then engrave the mold; then add anti-collision and brakes to the lawn mower. The technical equation and modeling method are:

[0112] Using PRO / ENGINEERWILDFIRE drawing software, set up a new working directory, create new parts, and sketch 2 concentric circles.

[0113] Open the variable section sweep (VarSectSweep) command, select the above two circles as the sweep trajectory and the reference trajectory.

[0114] Draw a straight line parallel to the plane of 2 circles, the length L=(D-d) / 2, and the projection line corresponding to the edge of the circle.

[0115] Establish parameter (PARAMETER) 1: C real number (real number), which can be assigned a value between 0.01-1 according to specific working conditions, such as 0.3; C is also called wave height. Establish parameter (PARAMETER) 2: N integer (integer), select a value between 2-100 according to specific working conditions, such as 13; N is also called wave number. Establish re...

Abstract

The invention relates to a lawn mower used for mowing lawns in courtyards, parks, and sides of roads, and other places. The lawn mower has three wheels, and reduces one of four wheels in a conventional four-wheel lawn mower, so turning and back-up are more flexible. The three-wheel lawn mower which has rotation angle in-gears of a grass head hitting flat rod to turn up a single front wheel is a series excited machine electric lawn mower having a chassis anticollision safety brake with a function wave disk. The lawn mower comprises an anticollision protecting device arranged on the front part of a lawn mower chassis, a brake with a function wave disk, the brake being arranged on the middle part of the lawn mower chassis, and a grass blocking pulling device and a grass shatter prevention device controlled by a remote stay cord.

Description

technical field [0001] The invention relates to a lawn mower used for mowing lawns in gardens, parks, roadsides and other places. It uses three wheels, saves one wheel of a normal four-wheel mower, and makes turning and reversing more flexible. The three-wheeled lawn mower with the grass head and the rotation angle of the flat rod to adjust 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 of the lawn mower chassis, as well as the lawn mower with remote pull rope control grass blocking device and grass anti-breaking device. Background technique [0002] Lawn mowers are widely used to mow grass in the manner chosen by people's preferences. When some pedestrians like and are used to using lawn mowers, they put a little more force on the rear upper armrest and ha...
