[0021] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments. Example
[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a stone grinding device proposed by the utility model includes a base 2, two ends of the base 2 are provided with brackets, and a grinding cylinder 1 is rotatably installed through the brackets, a driving device for driving the grinding cylinder 1 to rotate is also installed on the base 2, a driven component 6 engaged with the driving device is fixed on the grinding cylinder 1, a grinding cavity 11 is provided inside the grinding cylinder 1, a hollow grinding component 17 is fixed in the grinding cavity 11, a buffer 16 is filled between the grinding cavity 11 and the grinding component 17, and openings 12 are provided at both ends of the grinding cylinder 1, which penetrate the grinding cylinder 1 and are connected to the grinding cavity 11 from both ends respectively, and the openings 12 at both ends are detachably connected with sealing members 14.
[0023] In an embodiment, Figure 3 As shown, a plurality of concave connecting holes 13 are provided on the outer walls of the openings 12 at both ends of the grinding cylinder 1, and a plurality of through holes are provided at corresponding positions on the sealing member 14. Connectors are provided in the through holes for connecting the sealing member 14 to the grinding cylinder 1 and closing the openings 12 at both ends of the grinding cylinder 1.
[0024] In an embodiment, Figure 3 As shown, one end of the sealing member 14 close to the opening 12 of the grinding cylinder 1 has a boss 15 protruding from the end wall of the sealing member 14 , and the outer diameter of the boss 15 matches the inner diameter of the opening 12 .
[0025] In an embodiment, Figure 3 As shown, a groove concave inwardly toward the axial direction of the boss 15 is provided on the outer periphery of the boss 15 , and a sealing ring 151 is fixed in the groove.
[0026] In an embodiment, Figure 3 As shown, the grinding assembly 17 is a cylindrical hard hollow grinding disc fixedly installed in the grinding chamber 11.
[0027] In an embodiment, Figure 3 As shown in the figure, the inner diameter of the openings 12 at both ends of the grinding chamber 11 is smaller than the inner diameter of the hollow grinding disc, and the inner wall of the opening 12 and the inner wall of the hollow grinding disc are arranged in a stepped manner, so that when the stone to be polished is added from the opening 12 into the grinding chamber 11 and is polished by the grinding disc, it is blocked by the stepped structure of the inner wall of the opening 12 and the inner wall of the hollow grinding disc, and it is difficult to move into the openings 12 at both ends of the grinding cylinder 1.
[0028] Further, such as Figure 3 As shown, when the inner wall of the opening 12 and the inner wall of the hollow grinding disc are in a stepped structure, the axial length of the boss 15 structure of the seal 14 that matches the inner diameter of the opening 12 at both ends of the grinding cylinder 1 is the same as the axial length of the opening 12, so that the boss 15 structure of the seal 14 is completely filled in the opening 12 of the grinding cylinder 1, further blocking the stone from moving in the grinding cavity 11.
[0029] In an embodiment, Figure 3 and Figure 4 As shown, the buffer 16 is elastic sound-absorbing cotton, and the elastic sound-absorbing cotton is filled between the grinding disc and the grinding cavity 11 as the buffer 16. Specifically, the elastic sound-absorbing cotton can be filled in large quantities between the grinding disc and the grinding cavity 11 for multiple times to maintain the stability of the structure between the grinding disc and the grinding cavity 11 to reduce vibration and noise.
[0030] In an embodiment, Figure 1 and Figure 2 As shown, the driving device includes a driving member 5 fixedly mounted on a base 2, a reducer 4 connected to an output end of the driving member 5, and a driving gear 3 connected to an output shaft of the reducer 4, wherein the driving gear 3 is meshed with a driven component 6 for transmission.
[0031] In an embodiment, Figure 1 and Figure 2 As shown, the driven component 6 is a large gear ring fixed on the outer circumference of the grinding cylinder 1. The diameter of the large gear ring is larger than the diameter of the driving gear 3, which is used to amplify the torque applied to the large gear ring so that the large gear ring drives the grinding cylinder 1 to rotate and grind the stone inside the grinding cylinder 1.
[0032] The working principle of the stone grinding device in the embodiment is as follows: the grinding cylinder 1 is firmly supported on the base 2 by the bracket and can flexibly rotate around the brackets at both ends. A driving device is arranged on the base 2, including a driving member 5, a reducer 4 and a driving gear 3, which drives the large gear ring fixed on the grinding cylinder 1 to rotate, and drives the grinding cylinder 1 to rotate. A hard hollow cylindrical grinding disc is installed in the hollow grinding cavity 11 inside the grinding cylinder 1. The stone to be polished is added to the hollow grinding disc in the grinding cavity 11 through the openings 12 at both ends of the grinding cylinder 1, so that the stone located in the grinding disc is rotated when the grinding cylinder 1 rotates. The grinding wheels 12 and the stones 13 are in contact with each other, thereby grinding away the sharp protrusions on the outer layer of the stones. The openings 12 at both ends of the grinding cylinder 1 are closed by removable seals 14, which are tightly connected to the connecting holes 13 on the outer wall of the grinding cylinder 1 through connectors to achieve flexible disassembly. The seal 14 has a boss 15 structure that is engaged with the opening 12, so that the seal 14 is more firmly connected to the opening 12 of the grinding cylinder 1, and the sealing ring 151 in the card groove can further enhance the sealing performance to prevent the dust and debris generated during grinding from overflowing, while also playing a sound insulation role.
