DETAILED DESCRIPTION

[0024] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0025] like Figure 1-Figure 6 It is shown that the drum structure of the ball mill provided in this embodiment includes a mixing drum, which includes a first drum 5 and a second drum 9 that are movably connected. A rotating shaft is provided at one end of the first drum 5, and the first drum 5 is rotatably connected to the first bracket plate 4 through the rotating shaft. The first bracket plate 4 supports the first drum 5. A feed port 15 is provided at the other end of the second drum 9. The feed port 15 is hollow. The second drum 9 is rotatably connected to the second bracket plate 10 through the feed port 15, and a sealing plate 16 is installed on the outer end of the feed port 15 by bolts. By opening the sealing plate 16, steel balls and materials to be ground can be poured into the second drum 9.

[0026] In this embodiment, if Figure 2 and Figure 3 As shown, a connecting sleeve 13 is installed at the other end of the first roller 5, and a connecting sleeve 14 is installed at the other end of the second roller 9. A plurality of slide posts are installed on the inner side of the connecting sleeve 14, which cooperate with the slide grooves provided on the outer surface of the connecting sleeve 13, so that the installation can be more convenient. At the same time, the combination of the connecting sleeve 13 and the connecting sleeve 14 can achieve a better sealing effect on the connection between the first roller 5 and the second roller 9.

[0027] A base plate 1 is installed at the bottom of the mixing drum, and a placement groove is opened on the top of the base plate 1. The first bracket plate 4 and the second bracket plate 10 are both located in the placement groove, and the first bracket plate 4 is located at one end of the placement groove and is fixed by bolts. The second bracket plate 10 slides in the placement groove, and can connect and separate the first roller 5 and the second roller 9, so as to facilitate the pouring out of the ground material in the mixing drum; a motor 2 is installed on one side of the first bracket plate 4 in the placement groove, and the output end of the motor 2 is connected to the pulley 6 on the first roller 5 through a transmission belt, and the mixing drum is driven to rotate by the motor 2.

[0028] In this embodiment, if Figure 2 , Figure 3 and Figure 4 As shown, the first roller 5 and the second roller 9 are fixedly installed with a limit ring 7 near the port, the limit ring 7 on the first roller 5 is connected with one end of the limit column 8 by a bolt, and the limit ring 7 on the second roller 9 is slidably connected with the limit column 8. Correspondingly, a threaded rod 11 is threadedly connected to one end of the bottom plate 1 close to the second bracket plate 10, and the position of the second bracket plate 10 can be limited by rotating the threaded rod 11, and limit plates 17 are installed at both ends of the limit column 8.

[0029] Combination Figure 6As shown, a handle 19 is installed at one end of the threaded rod 11 for easy rotation, and the other end of the threaded rod 11 is rotatably connected to the bottom of the second bracket plate 10 through a rotating pad 18. Therefore, the second roller 9 can be pushed to move by rotating the threaded rod 11. When the first roller 5 and the second roller 9 are connected, the second roller 9 can be fixed by the threaded rod 11 to maintain stability during grinding.

[0030] In this embodiment, if Figure 1 and Figure 5 As shown, the bottom of the connection between the first roller 5 and the second roller 9 is located on the bottom plate 1 and a receiving plate 12 is installed. The top of the receiving plate 12 is an inclined surface, and a material discharge chute is opened on the inclined surface. When discharging materials, it can guide the dumped materials to prevent the materials from accumulating in the placement groove on the bottom plate 1.
