Multi-bit joint cleaning cutter for hard and brittle filling materials in expansion joints of cement concrete pavements
The invention discloses a multi-bit joint cleaning cutter for hard and brittle filling materials in expansion joints of cement concrete pavements. The multi-bit joint cleaning cutter is characterized in that geometrically quadrangular cutter bits are arranged on an L-shaped cutter body and are integrally connected with the cutter body, included angles beta between the center lines and the upper surfaces of the cutter bits range from 2 degrees to 85 degrees, included angles theta between the bottom surfaces and the upper surfaces of the cutter bits range from 1 degree to 65 degrees, the left rear end surface of the cutter body is perpendicular to the rear side surface of the cutter body, an included angle eta between the left rear end surface and the upper surface of the cutter body is equal to the included angles beta between the center lines and the upper surfaces of the cutter bits, the left front end surface of the cutter body coincides with the left side surface of the cutter bit at the leftmost end of the cutter body, an included angle lambda between the left front end surface and the rear side surface of the cutter body ranges from 6 degrees to 90 degrees, the right end surface of the cutter body coincides with the right side surface of the cutter bit at the rightmost end of the cutter body, and an included angle alpha between the right end surface and the rear side surface of the cutter body ranges from 8 degrees to 90 degrees. The multi-bit joint cleaning cutter has the advantages that the cleaned joint filling materials are not fragmentary, accordingly, the multi-bit joint cleaning cutter brings convenience for collecting the cleaned materials and is high in joint cleaning efficiency, and work environments and ambient environments can be prevented from being polluted.
