Abstract
The utility model provides a tool bit for rubbing crusher, it includes a hawk head form tool bit body that fuses with the handle of a knife body by anterior triangle -shaped work piece and assembly, in the triangle -shaped work piece on the propendent working face company of welding have polylith or many the carbide that clap into a row, the adjacent side of working face on integrative linking to each other have the handle of a knife body that has the transverse orientation hole, the back side of this handle of a knife body is provided with the arc fitting surface, just the width of anterior triangle -shaped work piece is greater than the width of rear portion assembly with the handle of a knife body, the perpendicular extension downwards in propendent working face lower part of triangle -shaped work piece has integrative handle of a knife body leading flank, the horizontal perpendicular to of shaft centre line of locating hole the leading flank, the upper portion side of triangle -shaped work piece forms the closed angle that is less than 45 with the working face, the carbide who forms one row is located the closed angle portion of working face, it has rational in infrastructurely, uses simple to operate, can improve holistic hardness of tool bit and abrasion resistance, improves rubbing crusher's life, reduces rubbing crusher's use cost, improves characteristics such as rubbing crusher availability factor and result of use.
Description
Technical field
The utility model relates to a kind of pulverizing cutter head being mostly installed on stump grinder and pulverizing for timber, belong to pulverizer technical field.
Background technology
Existing pulverizer cutter head, it is the core work parts of comminutor impeller work, cutter head therein includes handle of a knife and striking part, cutter head is operationally with impeller single direction rotation, thus realize the timber such as wood, branch crushed and the work such as grinding, therefore the abrasion of cutter head occurs mainly on the unilateral scope of attack；So once running into the timber having certain degree of hardness, being damaged or worn out of time one long easily generation cutter head, thus reduce using effect and the service life of pulverizer.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art to exist, and provide a kind of rational in infrastructure, easy to install and use, the overall hardness of cutter head and wear-resisting intensity can be improved, improve the service life of pulverizer, reduce the use cost of pulverizer, improve pulverizer service efficiency and the pulverizer cutter head of using effect.
The purpose of this utility model is completed by following technical scheme, a kind of pulverizer cutter head, it includes a Caput Accipiter shape body of tool bit being connected by anterior triangle operation block and assembling toolholder body, in described triangle operation block, the weldering on work surface that turns forward is connected with polylith or many hard alloys being arranged in a row, integrally being connected with the toolholder body with located lateral hole in described work surface adjacent side, the back side edge of this toolholder body is provided with arc fitting surface；And the width of described front portion triangle operation block is more than the width of rear portion assembling toolholder body.
As preferably: the work surface lower vertical that turns forward of described triangle operation block stretches downwards the toolholder body leading flank having one, the shaft centre line in hole, described location is laterally perpendicular to described leading flank, and the upper side of described triangle operation block forms the wedge angle less than 45 with work surface；Described shape hard alloy in a row is positioned at the corners of described work surface.
This utility model belongs to improvements over the prior art, it has rational in infrastructure, easy to install and use, and the cutter head using alloy can improve the overall hardness of cutter head and wear-resisting intensity, improve the service life of pulverizer, reduce the use cost of pulverizer, improve the feature such as pulverizer service efficiency and using effect.
