Abstract
Description
Technical field
The present invention relates to coal transporting breaking machine technical field, particularly a kind of crushing teeth assembly and apply the crushing toothed roller of this crushing teeth assembly.The invention still further relates to a kind of coal transporting breaking machine of this crushing toothed roller of application.
Background technology
Coal transporting breaking machine is a kind of engineering mechanical device for mass transport and transhipment, and crushing teeth assembly is as the main material treating apparatus of coal transporting breaking machine, and its service behaviour also gets more and more people's extensive concerning day by day.
In the current existing crushing teeth assembly course of work, material after pending or fragmentation completes can be carried by the drag conveyer be positioned at below crushing teeth assembly, but, because the assembly structure of existing crushing teeth assembly is comparatively complicated, and its assembling volume is larger, in equipment running process, very easily extruding is formed to the material be positioned at below crushing teeth assembly, the active force formed in extrusion process can be passed on the drag conveyer of below by material, the frictional force between drag conveyer associated component is caused to increase, and then accelerate the wearing and tearing of its associated components, the accident such as even cause scraper plate stuck, overall operation stability and the continuity of coal transporting breaking machine are had a strong impact on.
Therefore, how to simplify the assembly structure of crushing teeth assembly, and reduce or avoid its extruding force produced perpendicular to mass transport direction material to be the important technological problems that those skilled in the art need to solve at present.
Summary of the invention
The object of this invention is to provide a kind of crushing teeth assembly, the assembly structure of this crushing teeth assembly is simple, and it not easily produces the extruding force perpendicular to mass transport direction to material, and the present invention also provides the crushing toothed roller of this crushing teeth assembly of a kind of application.Another object of the present invention is to provide a kind of coal transporting breaking machine applying above-mentioned crushing toothed roller.
For solving the problems of the technologies described above, the invention provides a kind of crushing teeth assembly, comprise toothholder, the middle part of the front end face of described toothholder has cutter tooth installing hole, crushing cutter tooth is fitted with in described cutter tooth installing hole, the bottom surface of described toothholder is arc surface, and the bottom surface of described toothholder and mass transport direction tangent;
The leading section of the upper surface of described broken cutter tooth has rake face, and the front end of described rake face is provided with bite, the front end face of described broken cutter tooth has main rear knife face, and the angle after described master between knife face and described rake face is acute angle.
Preferably, after described master knife face and described broken cutter tooth bottom surface between be provided with some minor flanks, each described minor flank knife face to bottom surface of described broken cutter tooth after described master is arranged successively, angle between each described minor flank and described rake face reduces successively by its distributing order, and the angle between each described minor flank and described rake face is all less than the angle after described master between knife face and described rake face.
Preferably, some guide faces are provided with between the upper surface of described rake face and described broken cutter tooth, described guide face is arc surface, arrange successively from described rake face to the upper surface of described broken cutter tooth in each described guide face, line between the center of circle in each described guide face and the front end of described rake face and the angle between described rake face increase successively by its distributing order, and the line between the center of circle in each described guide face and the front end of described rake face and the angle between described rake face are all between 5 ° to 40 °.
Preferably, the leading section of the bottom surface of described broken cutter tooth is provided with back-up block, and described back-up block and described broken cutter tooth fix;
The front end face of described toothholder is provided with the stop block matched with described back-up block, and described stop block is positioned at the below of described cutter tooth installing hole.
Preferably, the inside top of described cutter tooth installing hole is provided with the overhead gage matched with described broken cutter tooth, and the inside bottom of described cutter tooth installing hole is provided with the lower baffle plate matched with described broken cutter tooth.
Preferably, the front end face of described toothholder is provided with stiffener, and described stiffener is positioned at the top of described cutter tooth installing hole.
Preferably, described toothholder and described crushing cutter between cog are fixed by the bearing pin running through described cutter tooth installing hole and described broken cutter tooth successively.
Preferably, the leading section of described rake face has the cutter groove suitable with bite, and described bite is fixedly welded in described cutter groove.
