Embodiment Construction

[0154] 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: use PRO / ENGINEER WILDFIRE drawing software, create a new working directory, create new parts, and sketch 2 pieces concentric circles.

[0155] Open the variable section sweep (Var Sect Sweep) command, select the above 2 circles as the sweep trajectory and the reference trajectory.

[0156] 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.

[0157] 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. Establish ...

Abstract

The invention relates to a mowing machine with a side-cutting large-width grass gathering function and an automatic-locking logarithmic spiral brake. The side-cutting large-width grass gathering function means that the mowing machine comprise a side-cutting device arranged on the two sides of the front wheels and on the edge of the cutting range of the mowing machine, such that the grass can be covered. The side-cutting device is composed of a side-cutting body (91), a side-cutting torsion spring (92), a side-cutting movable arm (93) and side-cutting trimming teeth (93d). A rotation shaft and the side-cutting torsion spring (92) are arranged on the side-cutting body (91). A side-cutting rotation sleeve (93c) is arranged on the side-cutting movable arm (93). The side-cutting rotation sleeve (93c) is movably arranged on the rotation shaft, and the side-cutting torsion spring (92) enters an assembly fixing position, such that the side-cutting movable arm (93) can be opened with a certain angle when mowing is carried out. The side-cutting movable arm (93) is also provided with the side-cutting trimming teeth (93d). The plan-view shape of the unilateral side-blade of the teeth of the side-cutting trimming teeth (93d) is a section of a logarithmic spiral with a constant pressure angle characteristic. The side-cutting trimming teeth has an arched back and a self-grinding function, such that slashing cutting and sliding cutting can be facilitated. Therefore, grass gathering and trimming are both facilitated.

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 located in the middle of the lawn mower chassis; it is a series excitation with a chassis anti-collision safety belt function wave disc brake The modification of the motor electric lawn mower also includes a logarithmic spiral brake with anti-collision insurance and self-stopping, a blower and a suction machine, a mowing head, and a liquid pipeline for watering, fertilizing and spraying The improvement of the multi-functional lawn mower of the hose reel, especially a lawn mower with the function of side-cutting and wide-width grass collection and automatic brake logarithmic helical brake. The invention also relates to a portable electric tool for blowing and sucking leaves in places such as flower beds, gardens, parks a...
