Abstract
Description
technical field
[0001] The invention relates to a lawn mower used for mowing lawns in gardens, parks, roads and other places. The anti-collision safety device at the front of the lawn mower chassis, and the series-excited motor electric lawn mower with a brake in the middle of the lawn mower chassis; it is a series-excited motor with a chassis anti-collision safety belt with a function wave disc brake A modification of an electric lawn mower, which includes a logarithmic spiral brake with anti-collision insurance and self-stopping, and a hose reel with a mowing head and a liquid pipeline for watering, fertilizing and spraying. Versatile 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 rear upper armrest and have a feeling of leaning and pressing down, which virtually increases the possibility of the front wheels...
Examples
Embodiment Construction
[0103] 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:
[0104] Painted by PRO / ENGINEER WILDFIRE picture Software, set up a new working directory, create a new part, and sketch 2 concentric circles.
[0105] Open the variable section sweep (Var Sect Sweep) command, select the above 2 circles as the sweep trajectory and the reference trajectory.
[0106] 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.
[0107] Establish parameter (PARAMETER) 1: C is a 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....
