AI Technical Summary

Technical Problem

In existing technologies, traditional methods of manual brush cutting, electric brush cutters, and large-scale mechanical brush removal have problems such as high labor intensity, low efficiency, insufficient cutting capacity, short endurance, and poor terrain adaptability when applied to large-scale forest areas of national reserve forests, making it difficult to meet the tending and management needs of complex terrains.

Method used

A portable brush cutter was designed, which uses a shoulder strap to carry the device on the shoulder. Combined with vibration damping materials and a vibration damping cylinder, it reduces the load on the arm muscles, absorbs device vibration, improves flexibility and work efficiency, and is suitable for different terrains.

Benefits of technology

It reduces the workload of operators, improves the efficiency and flexibility of brush clearing, enhances the ability to work for extended periods in complex terrain, and is suitable for tending and management of large areas of national reserve forests.

Abstract

This utility model discloses a portable brush cutter worn on a sling, belonging to the field of garden machinery technology. The portable brush cutter includes a working pole with a gasoline engine, cutting components, a handle, and a shoulder strap. One end of the handle has a control handle, and the other end has a secondary handle. The control handle has an on / off switch, a locking button, a safety switch, and a throttle control switch. During operation, the shoulder strap is fastened, and the shoulder strap is worn diagonally over the operator's shoulder and back, transferring the weight of the brush cutter from the arm to the shoulder and waist, reducing the load on the arm muscles and achieving a scientific weight distribution. The shoulder strap allows the entire brush cutter to be suspended, not only making it suitable for various terrains and increasing the flexibility of brush cutting, but also absorbing 40% of the swing energy of the entire brush cutter, greatly reducing the operator's workload and significantly improving brush cutting efficiency.
