Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the pot comprises a base 1, a cavity 2, a pot body 3, a positioning column 4, a circular ring 5, a first straight gear 6, a driving motor 7, a second straight gear 8, a rotary table 9, a protrusion 10, a valve 11 and a guide plate 12.

The embodiment is basically as shown in the attached figure 1: the accessory grinding device comprises a base 1. The base 1 is provided with a cavity 2 inside, and the top of the cavity 2 is communicated with the outside. The top welded fastening of base 1 has the pot body 3, and the top and the bottom of the pot body 3 are uncovered, and the inside of the pot body 3 communicates with base 1 cavity 2 each other, and the inner wall of the pot body 3 evenly opens has a plurality of internal threads that are parallel to each other. A plurality of grinding stones are uniformly loaded in the pot body 3. The center of the top surface of the base 1 is fixedly welded with a positioning column 4.

The positioning column 4 comprises an upper half part and a lower half part, wherein the upper half part of the positioning column 4 is of a circular truncated cone structure, the lower half part of the positioning column 4 is of a cylindrical structure, and the upper half part and the lower half part of the positioning column 4 are integrally formed. And a circular ring 5 is fixedly welded on the top surface of the positioning column 4, and the axial direction of the circular ring 5 is parallel to the horizontal plane. The outer wall of the lower half part of the positioning column 4 is horizontally and rotatably connected with a first straight gear 6. The top surface of the first straight gear 6 is coaxially welded and fixed with a rotary table 9, the outer diameter of the rotary table 9 is equal to the diameter of the addendum circle of the first straight gear 6, and the outer edge of the rotary table 9 is tightly abutted against the inner wall of the pot body 3. The top surface of the rotary table 9 is provided with a plurality of bulges 10 with arc-shaped outer surfaces which are integrally formed. A driving motor 7 is further fixed on one side of the adjacent positioning column 4 on the bottom surface of the cavity 2 through bolts, and an output shaft of the driving motor 7 faces to the right upper side vertically.

An output shaft of the driving motor 7 is coaxially connected and fixed with a second straight gear 8, and the second straight gear 8 is horizontally meshed with the right side of the first straight gear 6. The side wall of the pot body 3 is also provided with a through hole with a rectangular structure, and the through hole is positioned at the equal height position of the top surface of the turntable 9. The outer wall of the pot body 3 is hinged with a valve 11 for blocking the through hole at the through hole, a bolt is fixed on the outer wall of the valve 11 through threads, and the bolt is inserted into the outer wall of the pot body 3. A guide plate 12 is welded and fixed on the outer wall of the pot body 3 under the through hole, and the guide plate 12 is vertical to the outer wall of the pot body 3.

The specific implementation process is as follows: firstly, before use, the accessory to be ground and the grinding stone are uniformly added into the pot body 3 and are fully mixed. Then, the driving motor 7 is started, and the second spur gear 8 is driven by the driving motor 7 to rotate circumferentially. The second spur gear 8 drives the first spur gear 6 to rotate circumferentially. Because the first straight gear 6 is fixedly connected with the rotating disc 9, the first straight gear 6 and the rotating disc 9 rotate on the outer wall of the lower half part of the positioning column 4 in the circumferential direction. Due to the fact that the protrusions 10 on the top face of the rotary table 9 are irregular, in the rotating process of the rotary table 9, the protrusions 10 enable the grinding stones and the accessories to be displaced in the vertical direction and the horizontal direction, and the grinding stones and the accessories are continuously rubbed with each other to finally achieve the technical effect that the grinding stones grind and polish the accessories.

And finally, after grinding is finished, the driving motor 7 is closed, the door bolt is opened to open the valve 11 from the through hole, and after the valve 11 is opened, the materials in the pot body 3 flow out along the guide plate 12, so that the technical effect of collection is finally realized.

The above description is only an example of the present invention, and the common general knowledge of the known specific structures and characteristics of the embodiments is not described herein. It should be pointed out that to those skilled in the art, without departing from the structure of the present invention, a plurality of modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the utility of the present invention.
