[0002] At present, the sand mill is the most advanced and efficient grinding equipment with the widest material adaptability. Its grinding chamber is the narrowest, the gap between the stirring rods is the smallest, and the grinding energy is the most concentrated. With a high-performance cooling system and an automatic control system, continuous processing and continuous discharging of materials can be realized, greatly improving the production efficiency. The dispersion disc of the sand mill drives the grinding medium to move at a high speed to generate friction and shear, so that the material is ground and dispersed. The grinding chamber is forced-cooled. There are horizontal sand mills and vertical sand mills, such as cylindrical annular gap sand mills and tower sand mills, etc. Generally, it is wet grinding. The material is mixed and rotated with the grinding body under the action of the rotating grinding disc, and is ground and sheared by the grinding body and between various parts of the crushing chamber. There are horizontal sand mills and vertical sand mills, such as cylindrical annular gap sand mills and tower sand mills, etc. Generally, it is wet grinding.

[0003] At present, when the sand mill is in use, when the material directly enters the sand mill through the feed pipe, it will impact the connection part of the main shaft and the grinding shaft of the sand mill, affecting the stability of the connection part. And the direct entry of the material into the sand mill will cause blockage at the feed pipe part of the sand mill, affecting the grinding efficiency. Based on this, a sand mill with a buffering function is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a sand mill with a buffering function that has a simple structure and reasonable design in order to solve the above problems.

[0005] The utility model realizes the above purpose through the following technical solutions:

[0006] A sand mill with a buffering function includes a frame, a bearing seat, a main shaft, a cylinder body and a grinding shaft. The cylinder body is fixedly connected with a feed pipe at the top of one end of the bearing seat. A buffering mechanism for buffering and dredging materials is installed in the feed pipe. The grinding shaft is fixedly connected to one end of the main shaft. The buffering mechanism is sleeved on the connection part of the main shaft and the grinding shaft. The buffering mechanism shakes up and down on the grinding shaft through a protection mechanism.

[0007] As a further optimization solution of the utility model, the buffer mechanism includes a buffer disc slidably connected to one end of the bearing seat close to the cylinder block. A slider is fixedly connected to the part where the buffer disc is slidably connected to the bearing seat. A chute is opened on one side of the bearing seat close to the buffer disc. The slider is adapted to the chute. A buffer spring is fixedly connected to the bottom of the buffer disc. A fixed rod is fixedly connected to one end of the bearing seat close to the buffer disc. The bottom of the buffer spring is fixedly connected to the fixed rod.

[0008] As a further optimization solution of the utility model, a dredging shaft is fixedly connected to the top of the buffer disc. The dredging shaft is located in the feed pipe. The buffer disc is sleeved on the connecting part of the main shaft and the grinding shaft.

[0009] As a further optimization solution of the utility model, the protection mechanism includes a protection plate sleeved on the grinding shaft. Protection cloths are fixedly connected to the top and bottom of the protection plate. Slide columns are fixedly connected to both sides of the protection cloth. Limit blocks are fixedly connected to both sides of the protection plate.

[0010] As a further optimization solution of the utility model, a square groove is opened on the buffer disc. The protection plate is slidably connected in the square groove.

[0021] Embodiment

[0022] As Figures 1-6 shown, a sand mill with a buffer function includes a frame 1, a bearing seat 2, a main shaft 3, a cylinder block 5 and a grinding shaft 6. The bearing seat 2 is fixedly connected to the frame 1, the main shaft 3 is rotatably connected in the bearing seat 2, the other end of the main shaft 3 is fixedly connected with a belt pulley 4, the cylinder block 5 is installed at one end of the bearing seat 2, a discharge port 8 is opened at the end of the cylinder block 5 away from the bearing seat 2, a feed pipe 7 is fixedly connected to the top of one end of the cylinder block 5 where the bearing seat 2 is located, a buffer mechanism for buffering and dredging materials is installed in the feed pipe 7, the grinding shaft 6 is fixedly connected to one end of the main shaft 3, the buffer mechanism is sleeved on the connection part of the main shaft 3 and the grinding shaft 6, and the buffer mechanism shakes up and down on the grinding shaft 6 through a protection mechanism.

[0023] During use, the pulley 4 is connected to the driving motor through a belt. Then, the driving motor is started, and the material to be ground is added into the cylinder body 5 through the feed pipe 7. The material is ground by the grinding shaft 6. During the grinding process, the buffer mechanism buffers the material entering the cylinder body 5 and simultaneously dredges the feed pipe 7. The ground material is discharged through the discharge port 8.

[0024] As Figures 3-6 shown, the buffer mechanism includes a buffer plate 903 slidably connected to one end of the bearing seat 2 close to the cylinder body 5. A slider 902 is fixedly connected to the part where the buffer plate 903 is slidably connected to the bearing seat 2. A chute 901 is formed on one side of the bearing seat 2 close to the buffer plate 903. The slider 902 is adapted to the chute 901. A buffer spring 904 is fixedly connected to the bottom of the buffer plate 903. A fixed rod 905 is fixedly connected to one end of the bearing seat 2 close to the buffer plate 903. The bottom of the buffer spring 904 is fixedly connected to the fixed rod 905. A dredging shaft 906 is fixedly connected to the top of the buffer plate 903. The dredging shaft 906 is located inside the feed pipe 7. The buffer plate 903 is sleeved on the connecting part of the main shaft 3 and the grinding shaft 6. The protection mechanism includes a protection plate 1001 sleeved on the grinding shaft 6. Protection cloths 1002 are fixedly connected to the top and bottom of the protection plate 1001. Slide columns 1003 are fixedly connected to both sides of the protection cloths 1002. Limit blocks 1006 are fixedly connected to both sides of the protection plate 1001. A square groove is formed on the buffer plate 903. The protection plate 1001 is slidably connected inside the square groove. Grooves 1004 are formed on both sides of the inner wall of the square groove. Limit grooves 1005 are formed on both sides of the inner wall of the square groove. The protection cloths 1002 are fixedly connected inside the square groove. The slide columns 1003 are slidably connected inside the grooves 1004. The limit blocks 1006 are slidably connected inside the limit grooves 1005.

[0025] During use, when the material enters through the feed pipe 7, the material will fall on the buffer plate 903. The buffer plate 903 buffers the material, causing the material to disperse to both sides. And because the material falls on the buffer plate 903, the material will generate an impact force on the buffer plate 903. At the same time, the self - gravity of the material will also cause the buffer plate 903 to slide downward under the action of the chute 901 and the slider 902, causing the buffer plate 903 to squeeze the buffer spring 904. After the buffer spring 904 is compressed, it has elasticity, which in turn causes the buffer plate 903 to vibrate up and down. During the up - and - down vibration of the buffer plate 903, the dredging shaft 906 moves up and down inside the feed pipe 7 to dredge the feed pipe 7;

[0026] The buffering of the material is realized, preventing the material from directly hitting the connecting part of the main shaft 3 and the grinding shaft 6, ensuring the stability of the connection. At the same time, the dredging of the feed pipe 7 is realized, preventing the blockage of the feed pipe 7, thereby ensuring the grinding efficiency;

[0027] Meanwhile, during the up-and-down shaking of the buffer disc 903, the protection plate 1001 will move up and down relative to the buffer disc 903 back and forth, thereby causing the limit block 1006 to slide within the limit groove 1005, and at the same time causing the protection cloth 1002 to fold and unfold back and forth under the action of the groove 1004 and the sliding column 1003, so that the buffer disc 903 can always protect the connection part of the main shaft 3 and the grinding shaft 6;

[0028] Furthermore, the protection of the connection part of the main shaft 3 and the grinding shaft 6 is further realized, preventing materials from entering the connection part of the main shaft 3 and the grinding shaft 6 and causing wear to the connection part of the main shaft 3 and the grinding shaft 6, which affects the transmission efficiency, thus ensuring the grinding efficiency.

[0029] The above-described embodiments merely represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
