Figures 1-4As shown, a dry mortar grinding device according to an embodiment of the present invention includes a grinding box 1. A feed inlet 2 is provided on the top surface of the grinding box 1, and a feed cylinder 3 is installed above the feed inlet 2. A reduction motor 5 is fixedly installed at the bottom of the grinding box 1, and a threaded rod 6 is fixedly installed at the output end of the reduction motor 5. A tower-shaped grinding table 7 is fitted onto the surface of the threaded rod 6, and a mounting hole 21 is provided at the center of the tower-shaped grinding table 7. The threaded rod 6 extends to the inside of the mounting hole 21, and a locking nut 22 is threaded onto the upper end of the threaded rod 6. The conical surface of the tower-shaped grinding table 7 is provided with a first grinding surface 8, a second grinding surface 9, and a third grinding surface 10 in a stepped manner from top to bottom. An upper grinding ring 15, a middle grinding ring 16, and a lower grinding ring 17 are sequentially arranged from top to bottom on the inner wall of the grinding box 1, and the inner rings of the upper grinding ring 15, the middle grinding ring 16, and the lower grinding ring 17 are all provided with conical grinding surfaces 26. Furthermore, the gaps between the multiple conical grinding surfaces 26 and the first grinding surface 8, the second grinding surface 9, and the third grinding surface 10 decrease sequentially from top to bottom. The top surfaces of the upper grinding ring 15, the middle grinding ring 16, and the lower grinding ring 17 are all provided with rectangular grooves 24, and the inner side of the rectangular grooves 24 is provided with through holes 25. Bolts connected to the inner wall of the grinding box 1 are inserted into the through holes 25. For the geared motor 5 and the bin wall vibrator 4, the control method of this utility model is to control them by manually starting and stopping the switch. The wiring diagram of the power components and the power supply are common knowledge in this field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring arrangement will not be explained in detail. In order to fit the first grinding surface 8, the second grinding surface 9, and the third grinding surface 10, the inner diameter of the inner ring of the upper grinding ring 15, the middle grinding ring 16, and the lower grinding ring 17 increases sequentially from top to bottom.

[0024] In one embodiment, a bin wall vibrator 4 is fixed to the side wall of the feed cylinder 3, and a number of springs 19 connected to the top surface of the grinding box 1 are arranged around the bottom surface of the feed cylinder 3. A rubber telescopic sleeve 18 is installed around the periphery of the springs 19. This structure has the functions of anti-blocking and uniform feeding, which is conducive to improving the continuity and smoothness of feeding.

[0025] In one embodiment, the top surfaces of the upper grinding ring 15, the middle grinding ring 16, and the lower grinding ring 17 are all surrounded by a plurality of rectangular grooves 24, and each rectangular groove 24 has a through hole 25 on its inner side. The upper part of the inner ring of the upper grinding ring 15, the middle grinding ring 16, and the lower grinding ring 17 is provided with a flared material guide. The flared material guide makes it easy to receive the falling dry powder mortar. The rectangular grooves 24 and the through holes 25 make it easy to install the upper grinding ring 15, the middle grinding ring 16, and the lower grinding ring 17 with bolts, making the upper grinding ring 15, the middle grinding ring 16, and the lower grinding ring 17 detachable, which is convenient for later maintenance and cleaning.

[0026] In one embodiment, a ring-shaped discharge shell 11 is fixed to the lower inner side of the grinding box 1, and the discharge shell 11 covers the periphery of the output end of the geared motor 5. A ring-shaped steel mesh 13 is embedded and installed at the edge of the top surface of the discharge shell 11, and a slope surface 12 is provided inside the discharge shell 11 corresponding to the ring-shaped steel mesh 13. Two discharge nozzles 14 are provided at the bottom of the lower side of the grinding box 1 corresponding to the bottom of the slope surface 12. With this structure, dry powder mortar that is easy to grind passes through the ring-shaped steel mesh 13 and is discharged from the discharge nozzles 14 under the action of the slope surface 12, which facilitates material discharge.

[0027] In one embodiment, the top surface of the tower-shaped grinding table 7 is provided with a cone 23, and the bottom of the cone 23 is provided with a circular plug extending into the inner side of the mounting hole 21. This structure prevents the falling dry mortar from accumulating, which is beneficial for continuous grinding.

[0028] In one embodiment, the top surface of the grinding box 1 has a circular opening, and a circular cover plate is detachably installed inside the circular opening. Two guide plates 20 are welded obliquely to the bottom surface of the circular cover plate. The feed port 2 is located at the center of the circular cover plate. With this structure, by removing the circular cover plate, the feed cylinder 3 is removed from the grinding box 1, and the circular opening is exposed, which facilitates the disassembly and cleaning of the upper grinding ring 15, the middle grinding ring 16 and the lower grinding ring 17. The two guide plates 20 are used to guide the dry powder mortar into the inside of the upper grinding ring 15.

[0029] Working principle:

[0030] In use, the dry mortar to be ground is first put into the feed cylinder 3. The vibrator 4 installed on the side wall of the feed cylinder 3 is then activated, causing the vibration generated by the vibrator 4 to directly act on the feed cylinder 3. This, in turn, amplifies the vibration effect of the feed cylinder 3 by several springs 19 installed at the bottom of the feed cylinder 3 and the circular rubber telescopic sleeve 18 surrounding it. This allows the dry mortar in the feed cylinder 3 to be injected into the grinding chamber 1 through the small-diameter nozzle at the bottom of the feed cylinder 3. During grinding, the reduction motor 5 installed at the bottom of the grinding chamber 1 is activated. Due to the vibration on the conical surface of the tower-shaped grinding table 7, the mortar is drawn from the top... The grinding chamber 1 is arranged in a stepped manner with a first grinding surface 8, a second grinding surface 9, and a third grinding surface 10. An upper grinding ring 15, a middle grinding ring 16, and a lower grinding ring 17 are bolted to the inner wall of the grinding chamber 1. The gap between the conical grinding surface 26 of the inner ring of the upper grinding ring 15, the middle grinding ring 16, and the lower grinding ring 17 and the first grinding surface 8, the second grinding surface 9, and the third grinding surface 10 decreases from top to bottom. As the output end of the reduction motor 5 drives the tower-shaped grinding table 7 to rotate, the dry powder mortar added at the feed port 2 undergoes multi-stage fine grinding in sequence.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
