Description
Technical Field
The invention relates to a tree stump cutting tool, and belongs to the field of cutting tools.
Background
The stump grinder is a common large-scale grinder, the most main part is a cutting tool at the top and is the part which is easy to damage, because the stump grinder is frequently contacted with the stump, a base and a cutter head of the common stump cutting tool are integrated, because of production relation, a mold is produced to be integrally formed, once a cutter body of the integrally formed cutter is damaged, the cutter body needs to be completely replaced, the cutter head is inconvenient, and an alloy cutter head is welded on the cutter body, so that the whole cutter head body needs to be replaced when a hard alloy layer is damaged.
Disclosure of Invention
Aiming at the defects of the prior art, the combined stump cutting tool is formed by adopting a split combination mode, and the replacement groove is formed between the alloy layer and the body of the tool, so that the hard alloy layer is convenient to replace and overhaul, the service time of the whole tool is shortened, and the efficiency is higher.
In order to achieve the purpose of the invention, the stump cutting tool comprises a rectangular stump cutting tool base and a stump cutting tool body arranged on the upper portion of the base, wherein an inwards concave assembly clamping groove is formed in the tail portion of the stump cutting tool base, a circular threaded assembly hole is formed in the center of the assembly clamping groove, the threaded assembly hole transversely penetrates through the stump cutting tool base, a parallel assembly surface which is embedded with the stump cutting tool body is arranged at the top of the stump cutting tool base, a protruding positioning block is arranged at the front end of the assembly surface, and the top of the positioning block is triangular.
Preferably, the method comprises the following steps: the pile cutting tool body is in a long strip shape, an inward concave long strip-shaped working face with two side edges higher than the middle is arranged at the top of the pile cutting tool body, a semicircular concave notch is arranged at the tail end of the working face, the size of the concave notch is the same as that of an assembling clamping groove of the inner concave of the tail of the pile cutting tool base, a semicircular alloy tooth holder used for embedding hard alloy is arranged at the front end of the working face, a replacing groove used for replacing the hard alloy is reserved between the hard alloy holder and the hard alloy, an assembling face is arranged at the bottom of the pile cutting tool body and fixed with the assembling face on the bottom pile cutting tool base, and a positioning hole corresponding to a positioning block is arranged on the assembling face of the pile cutting tool base.
The utility model discloses an improvement to prior art, it has rational in infrastructure, uses simple to operate, and the cutter structure fastness of combination formula is good, and is wear-resisting to reduce use cost, improve characteristics such as work efficiency.
