Abstract

Provided is a mower with the functions of irrigating, fertilizing, pesticide spraying and automatic anti-collision logarithmic spiral braking. The mower is a multifunctional mower provided with an anti-collision safety logarithmic spiral brake and a pipe winder with a liquid pipe for irrigating, fertilizing and pesticide spraying. Four assemblies are added to a common lawn mower and comprise the support assembly of a storage battery provided with a charger and an inverter, the cutting device assembly dragged by a series excitation motor, the pipe winder assembly achieving the functions of irrigating, fertilizing and pesticide spraying, and the brake assembly. The functions of irrigating, fertilizing and pesticide spraying are added, the use range is wide, and the movement area is large. Liquid fertilizer used for fertilizing and contained in the pipe of the pipe winder is obtained by adding soluble fertilizer to water percentagewise. Alternatively, liquid fertilizer used for pesticide spraying and contained in the pipe of the pipe winder is obtained by adding soluble pesticides to water percentagewise.

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....
