Abstract
The utility model discloses a coal gangue grinding machine. The coal gangue grinding machine comprises a stander and a feeding hopper, wherein a cavity is formed in the stander, and the feeding hopper is arranged at the top of the stander and is communicated with the cavity; a spiral feeding mechanism is connected between the feeding hopper and the stander, a grinding assembly is arranged in the cavity, a meshing hole of the grinding assembly is opposite to a feeding end of the spiral feeding mechanism, and a conveying belt is further arranged in the cavity and is located right below the meshing hole; a pair of cooperatively used compression rolls is arranged between the grinding assembly and the conveying belt, and movable bearings are connected between the compression rolls and the stander. According to the coal gangue grinding machine, by arranging the spiral feeding mechanism, the impact force generated in a falling process of coal gangue can be effectively reduced, and the service life of a crushing knife set is prolonged; the sizes of coal gangue fine grains can be further reduced due to the compression rolls, so that sufficient preparation is made for a follow-up work; the coal gangue grinding machine is simple in structure, is convenient to use and is suitable for being popularized and used.
Description
Technical field
The utility model relates to a kind of gangue grater.
Background technology
Existing gangue grater general configuration is frame, hopper and crushing cutter group, and such structure is comparatively simple, and has following shortcoming:
One, gangue directly directly falls in crushing cutter group by hopper, produces larger impulsive force, and crushing cutter group is produced to certain destruction.
Two, the gangue after the fragmentation of crushing cutter group is used directly to manufacture briquette, and some larger ore particles may be left over, and affect the quality of briquette.
Summary of the invention
The technical problems to be solved in the utility model is to provide one can effectively guarantee gangue particulate size, and gangue grater simple in structure, easy to use.
For addressing the above problem, the utility model adopts following technical scheme:
A kind of gangue grater, comprise that an inside has the frame of cavity, and be arranged on frame top, and the material bin communicating with cavity, between material bin and frame, be connected with screw feed mechanism, in cavity, be provided with broken assembly, the broken articulation port of assembly is relative with the feeding end of screw feed mechanism, in cavity, is also provided with conveyer belt, and conveyer belt is positioned under articulation port, between broken assembly and conveyer belt, be provided with a pair of pressure roller being used in conjunction with, between this pressure roller and frame, be connected with live bearing.
As preferred technical scheme, described screw feed mechanism comprises the first barrel, the second barrel, feeding rod and ring flange, and described the first barrel is connected by ring flange is dismountable with the second barrel, and feeding rod assigns in the first barrel and the second barrel.
As preferred technical scheme, described conveyer belt end is provided with material collecting tank, and the width of described material collecting tank is not less than the width of conveyer belt.
The beneficial effect of the utility model gangue grater is: by set screw feed mechanism, impulsive force when can effectively reducing gangue whereabouts, extend the service life of crushing cutter group, can dwindle further the size of gangue particulate by set pressure roller, for sufficient preparation is carried out in follow-up work, and the utility model structure is comparatively simple, use more for convenience, be applicable to promoting the use of.
Accompanying drawing explanation
For ease of explanation, the utility model is described in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the structural representation of the utility model gangue grater;
Fig. 2 is the structural representation of the screw feed mechanism in the utility model gangue grater.
The specific embodiment
Consult a kind of gangue grater shown in Fig. 1 and Fig. 2, comprise that an inside has the frame 1 of cavity, and be arranged on frame 1 top, and the material bin 2 communicating with cavity, between material bin 2 and frame 1, be connected with screw feed mechanism 3, in cavity, be provided with broken assembly 4, the broken articulation port of assembly 4 is relative with the feeding end of screw feed mechanism 3, in cavity, be also provided with conveyer belt 5, conveyer belt 5 is positioned under articulation port, between broken assembly 4 and conveyer belt 5, be provided with a pair of pressure roller being used in conjunction with 6, between this pressure roller 6 and frame 1, be connected with live bearing 7.
Wherein, described screw feed mechanism 3 comprises the first barrel 8, the second barrel 9, feeding rod 10 and ring flange 11, and described the first barrel 8 is connected by ring flange 11 is dismountable with the second barrel 9, and feeding rod 10 assigns in the first barrel 8 and the second barrel 9.
Described conveyer belt 5 ends are provided with material collecting tank 12, and the width of described material collecting tank 12 is not less than the width of conveyer belt 5.
The beneficial effect of the utility model gangue grater is: by set screw feed mechanism, impulsive force when can effectively reducing gangue whereabouts, extend the service life of crushing cutter group, can dwindle further the size of gangue particulate by set pressure roller, for sufficient preparation is carried out in follow-up work, and the utility model structure is comparatively simple, use more for convenience, be applicable to promoting the use of.
The above, be only the specific embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
