Abstract

The invention provides a dismountable cutting tool assembly having a dust setting function and belongs to the technical field of accessories of a cutting device for a coal mine mining machinery. The dismountable cutting tool assembly comprises conical cutting teeth, a conical tooth holder, a dust setting connecting base and a fixing block; each conical cutting tooth comprises a tooth handle, a tooth shoulder, a tooth rod and a conical part; each tooth handle and each tooth rod are both of a cylindrical structure; the tooth shoulder is of a circular platform structure; the bottom surface of each tooth shoulder is connected with the corresponding tooth handle; the top surface of each tooth shoulder is connected with the corresponding tooth rod through an annular transition curve surface; theconical part is positioned on the tooth rod; hard alloy is brazed at the top of the conical part; the circumferential surface is uniformly provided with a plurality of oval bending resisting beams; the conical tooth holder is provided with a mounting hole; the lower part of the conical tooth holder is provided with a quick inserting tenon; the dust setting connecting base is provided with an inserting groove; the bottom surface of the dust setting connecting base is provided with a water distribution interface; the rear part of the dust setting connecting base is provided with a dust settingnozzle; an internal water channel is arranged inside the dust setting connecting base; and the fixing block is used for sealing an inserting opening of the inserting groove. The dismountable cutting tool assembly having the dust setting function can improve the bending resistance of the cutting teeth and simultaneously realizes detachable connection between the tooth holder and a cutting head or acutting roller.

Description

technical field [0001] The invention belongs to the technical field of coal mining machinery cutting device accessories, and specifically discloses a detachable cutting tool assembly with the function of reducing dust. Background technique [0002] The pick is installed in the mounting hole of the cutting head tooth seat, and can freely rotate around its axis in the mounting hole. During the working process of the roadheader, the pick is directly in contact with the coal mass and rock mass. With the accumulation of time at any time, the circumferential surface of the tapered part of the pick tooth bar will be uniformly worn until the length of the tooth bar is shortened to unusable. Replace with new picks. Some existing picks prolong the service life of the pick by reducing the angle of the tapered part and coating the wear-resistant material, but this method is actually to make the pick into a composite structure of two materials. The bending resistance of the gear-tooth ...
