Mowing machine with side-cutting large-width grass gathering function and automatic-locking logarithmic spiral brake

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.

Problems solved by technology

If you put the blower on the lawn mower, it is a technological progress from carrying it to rolling on wheels. It not only reduces the burden on people, but also the grass bag on the lawn mower can be much larger, and the continuous working time is longer.
