Portable electric rubber tapping knife

Abstract

The invention discloses a portable electric rubber tapping knife which comprises a rotary knife head, a limit device, a transmission assembly, a power assembly, a connecting assembly and a handle. The rotary knife head is composed of a cylindrical knife body and screw blades radially distributed on the cylindrical knife body, and each screw blade is composed of an axial blade body and a radial blade body; a limit cover arranged on the exterior of the rotary knife head in a sleeving mode serves as the limit device, one end of the limit device is provided with a screwed joint, the other end of the limit device is provided with a circular opening, and the side face of the limit device is provided with an axial cutting opening and a chip discharging opening; the axial blade bodies are located at the axial cutting opening of the limit device, and the radial blade bodies are located at the circular opening of the limit device. The rubber tapping knife is simple in structure, convenient to use, low in requirement for a rubber tapping technique of a rubber tapping worker and capable of significantly improving the rubber tapping efficiency, saving the production cost, meeting the usage of inclined upward tapping and inclined downward tapping and the requirements of body mechanics and being reused.

Description

technical field [0001] The invention relates to the natural rubber industry. The rubber tapping knife is driven by a motor, greatly improves the rubber tapping efficiency, reduces the technical difficulty of rubber tapping and the labor intensity of rubber workers, and saves production costs. Background technique [0002] At present, natural rubber tapping still uses the 100-year-old manual tapping method. Using a "V"-shaped traditional rubber tapping knife to cut rubber bark is not only labor-intensive and labor-intensive, but also requires relatively high technical requirements for rubber workers and is difficult to control. The depth and thickness of the rubber tapping can easily lead to different depths of the cut, which can damage the rubber tree wood layer, lead to dead skin disease or other diseases, thereby reducing the latex output and causing greater losses to production. In the early stage, some people also invented the use of mechanical force to drive the blade t...

AI Technical Summary

Problems solved by technology

Under the current background of increasingly tense labor force, sharp increase in labor costs, and bad rubber price market conditions, production enterprises cannot make ends meet, resulting in an embarrassing situation where there is glue that cannot be cut, and there is no one to cut the rubber. The natural rubber industry is facing a severe test.
