[0002] A crusher, also known as a rock crusher, is a crushing machine used in the processing of metal ores and non-metallic ores. It can break the mined ore into small particles through extrusion, bending, impact and splitting.

[0003] The working principle of the crusher is mainly to use mechanical force to crush and pulverize materials. The crusher sends the material into the crushing chamber through the feed port and crushes the material through the tooth roller and hammer. The fine teeth on the surface of the tooth roller are the key components of the crusher. The degree of wear directly affects the crushing efficiency. If the fine teeth cannot be replaced, the wear of the tooth roller will become increasingly serious as the use time increases, resulting in a decrease in crushing capacity and an inability to meet production needs.

[0022] The following is combined with Figure 1-5 To further explain this application in detail,

[0023] The present application embodiment discloses a fine tooth structure of a screening crusher. Figure 1-5 A fine-toothed structure of a screening crusher comprises a tooth roller body 1, the inner cavity of the tooth roller body 1 is fixedly connected with a central shaft 7, a clamping strip 5 is slidably installed in the inner cavity of the tooth roller body 1, the number of the clamping strips 5 is several, the surface of the clamping strip 5 is fixedly connected with rotating teeth 6, the number of the rotating teeth 6 is several, the front and rear sides of the tooth roller body 1 are both installed with clamping mechanisms 2, and the front side of the clamping mechanism 2 is installed with a fixing mechanism 3;

[0024] The clamping mechanism 2 includes a fixed block 201 and a clamping plate 204. One side of the fixed block 201 is fixedly connected to the surface of the clamping strip 5. The number of fixed blocks 201 is several. The inner cavity of the fixed block 201 is fixedly connected to the rotating shaft 202. The surface of the rotating shaft 202 is rotatably connected to the rotating block 203. The clamping plate 204 is fixedly connected to one side of the gear roller body 1. The number of clamping plates 204 is several. The clamping plate 204 is clamped to the inner cavity of the rotating block 203.

[0025] Reference Figure 5 The surface of the fixed block 201 is movably connected with an annular support plate 205, and one side of the annular support plate 205 is fixedly connected with an annular pressure plate 206. The inner cavity of the annular support plate 205 is hollow and fits the surface of the fixed block 201. The annular support plate 205 is provided to support the annular pressure plate 206. The annular pressure plate 206 is provided to press the clamping plate 204 to prevent the clamping plate 204 from falling off from the inner cavity of the rotating block 203.

[0026] Reference Figure 2 and Figure 4 , both sides of the clamping strip 5 are provided with a slide groove 8, both sides of the slide groove 8 are slidably connected with a triangular clamping block 4, the triangular clamping block 4 is fixedly connected to the inner cavity of the gear roller body 1, and the triangular clamping block 4 is in a triangular shape. Through the coordinated use of the triangular clamping block 4 and the slide groove 8, the clamping strip 5 can be effectively inserted into the inner cavity of the gear roller body 1, so as to avoid the clamping strip 5 falling off from the inside of the gear roller body 1 during the crushing operation, causing unnecessary losses;

[0027] Reference Figure 2 and Figure 3 The fixing mechanism 3 includes a disc 301, which is fixedly connected to the surface of the gear roller body 1, and a threaded rod 302 is fixedly connected to one side of the disc 301. The insides of the disc 301 and the threaded rod 302 are fixedly connected to the surface of the central axis 7. A fixed disc 304 is threadedly connected to one side of the surface of the threaded rod 302, and a manual disc 308 is fixedly connected to one side of the fixed disc 304. Through the setting of the threaded rod 302, the threaded sleeve 305 and the connecting rod 306 can be moved on the surface thereof, and then the pressing block 307 presses and fixes the annular pressure plate 206. Through the setting of the manual disc 308 and the fixed disc 304, the position of the threaded sleeve 305 can be limited, thereby preventing the threaded sleeve 305 from being passively separated from the surface of the threaded rod 302, thereby ensuring the stability of the threaded sleeve 305 when working;

[0028] Reference Figure 3The surface of the threaded rod 302 is threadedly connected with a threaded sleeve 305, and the surface of the threaded sleeve 305 is fixedly connected with a connecting rod 306. There are three connecting rods 306, and one side of the connecting rod 306 is fixedly connected with a pressing block 307. Through the setting of the threaded sleeve 305, the connecting rod 306 can be driven to move on the surface of the guide ring 303, and through the setting of the pressing block 307, the annular pressure plate 206 is pressed on the surface of the fixed block 201, and then the rotating block 203 is fixed to prevent the clamping plate 204 from falling off from the inner cavity of the rotating block 203;

[0029] Reference Figure 3 The surface of the pressure block 307 is movably connected with a guide ring 303, and the interior of the guide ring 303 is a hollow structure. One side of the guide ring 303 is fixedly connected to the surface of the annular pressure plate 206. Through the setting of the guide ring 303, the pressure block 307 is limited, and the pressure block 307 can be rotated and moved inside it, avoiding unstable clamping of the pressure block 307 on the annular pressure plate 206.

[0030] Working principle: When installation is required, first insert the clamping strip 5 into the inner cavity of the gear roller body 1, so that the triangular clamping block 4 is clamped in the inner cavity of the slide groove 8, and then rotate the rotating block 203 to make it rotate on the surface of the rotating shaft 202. The inner cavity of the rotating block 203 is clamped to the surface of the clamping plate 204, so that it is annular and clamped to each other. After the clamping is completed, the annular support plate 205 and the annular pressure plate 206 are placed on the surface of the clamping plate 204, and then the threaded sleeve 305 is rotated. 5 is threadedly connected with the threaded rod 302 to move the threaded sleeve 305, and the movement of the connecting rod 306 drives the pressing block 307 to move until the pressing block 307 is in close contact with the annular pressure plate 206, so that the annular support plate 205 and the annular pressure plate 206 are tightly pressed against the surface of the fixed block 201, and the stability of the clamping of the rotating block 203 and the clamping plate 204 is improved. Then, the manual disk 308 and the fixed disk 304 are rotated. The manual plate 308 and the fixed plate 304 are moved by the threaded connection of the rod 302, and the fixed plate 304 is moved by the movement of the manual plate 308 until the surface of the fixed plate 304 is in close contact with one side of the threaded sleeve 305, and then the connecting rod 306, the connecting rod 306 and the pressing block 307 are limited, so that the manual plate 308 and the fixed plate 304 can block the threaded sleeve 305 after the threaded sleeve 305 is loosened during the crushing operation, so as to realize the installation of the clamping strip 5, and reversely When removing, the manual disk 308 is detached from the surface of the threaded rod 302, and then the threaded sleeve 305 is detached from the surface of the threaded rod 302. At this time, the guide ring 303, the annular pressure plate 206 and the annular support plate 205 lose pressure, and they are taken out. Then, the rotating block 203 is rotated to disengage the rotating block 203 from the clamping plate 204, and then the rotating tooth 6 is pulled. The movement of the rotating tooth 6 drives the clamping strip 5 to move, so that the triangular clamping block 4 is completely disengaged from the interior of the slide groove 8, thereby realizing the removal of the clamping strip 5.

[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
