Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0024] Combine Figures 1-4 A cement mill discharging device includes a shell 1, a filter screen 3 arranged inside the shell 1 and a discharge pipe 2 connected to one side of the shell 1, a top moving structure 5 is arranged inside the shell 1, and a rolling scraping structure 6 is also arranged inside the shell 1.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Example 1:

[0027] See also Figure 1-Figure 5 The pushing structure 5 includes a motor 52 arranged on one side of the shell 1, a rotating rod 53 arranged at the output end of the motor 52, and a cam 54 at both ends of the rotating rod 53. The pushing structure 5 also includes connecting blocks 55 arranged on both sides of the filter 3. An extension plate 51 is provided on one side of the shell 1. The extension plate 51 is used to fix the motor 52. One end of the rotating rod 53 is rotatably connected to the inner wall of the shell 1. A groove 57 is provided on the inner wall of the shell 1. A tension spring 56 is provided inside the groove 57. One end of the tension spring 56 is connected to the connecting block 55. The connecting block 55 slides in the groove 57. A cam 2 58 is symmetrically provided at the outer end of the middle part of the rotating rod 53. The cam 2 58 is used to push the middle part of the filter 3, which greatly improves the feeding speed.

[0028] The scraping structure 6 includes a multi-stage hydraulic cylinder 62 arranged on one side of the shell 1, and a sleeve block 63 arranged at the output end of the multi-stage hydraulic cylinder 62. The scraping structure 6 also includes a scraper roller 66 that is rollingly connected to the inside of the shell 1. A fixed plate 61 is provided on the other side of the shell 1. The fixed plate 61 is used to fix the multi-stage hydraulic cylinder 62. A rotating shaft 64 is provided at both ends of the scraper roller 66. The rotating shaft 64 is rotatably connected to the sleeve block 63. A long groove is provided on the inner wall of the shell 1, and a rack 67 is provided inside the long groove. A gear 65 is provided at the outer end of the rotating shaft 64, and the gear 65 is meshed with the rack 67. The continuous scraping of the scraper roller 66 can clean up impurities at the early stage of accumulation, ensuring the smooth flow of the filter holes. The pressure plate 42 descends to expose the diverter pipe 43, thereby increasing the discharge channel so that the material can be discharged from the discharge pipe 2 and the diverter pipe 43 at the same time, meeting the discharge speed requirements of different production stages.

[0029] A diversion structure 4 is provided inside the shell 1. The diversion structure 4 includes springs 41 arranged inside the shell 1. There are four groups of springs 41 distributed at equal intervals. A pressure plate 42 is provided on the top of the four groups of springs 41. A diversion pipe 43 is connected to the other side of the shell 1. The diversion pipe 43 is staggered with the discharge pipe 2, and the diversion pipe 43 is higher than the height of the discharge pipe 2.

[0030] Specifically, when in use, cement material is discharged from the mill to the filter screen 3, and the motor 52 fixed by the extension plate 52 on one side of the shell 1 is started to drive, and the motor 52 drives the rotating rod 53 at the output end to rotate, and one end of the rotating rod 53 is rotatably connected to the inner wall of the shell 1. Since connecting blocks 55 are provided on both sides of the filter screen 3, the connecting blocks 55 slide in the grooves 57, and the rotating rod 53 drives the cam 54 on the surface to rotate upward, and the cam 54 pushes the filter screen 3 connected to the connecting block 55 upward, so that the connecting block 55 compresses and accumulates force on the tension spring 56. When the rotating rod 53 drives the cam 54 downward, the cam 54 does not push the connecting block 55, and the connecting block 55 moves downward through the tension spring 56 and the self-weight of the filter screen 3, thereby vibrating the filter screen 3 up and down, which greatly improves the speed of material discharge. In addition, this vibration can also avoid the adhesion of cement due to static state, thereby ensuring the continuous smooth flow of the material discharge channel.

[0031] The multi-stage hydraulic cylinder 62 fixed to the fixed plate 61 on one side of the shell 1 is driven, and the multi-stage hydraulic cylinder 62 drives the output sleeve block 63 to move, and the sleeve block 63 drives the rotating shaft 64 connected to the rotation to move, and the rotating shaft 64 drives the gear 65 to engage with the rack 67, and the rack 67 is fixed inside the long groove starting from the inner wall of the shell 1. The rotating shaft 64 drives the scraper roller 66 to rotate, and the scraper roller 66 scrapes the impurities on the surface of the filter screen 3. The continuous scraping of the scraper roller 66 can clean up the impurities at the early stage of accumulation, ensure the smooth flow of the filter holes, and achieve the effect of anti-blocking. As the scraper roller 66 rolls, the impurities are rolled and pushed to one side of the filter screen 3, which is convenient for unified cleaning;

[0032] After being filtered through the filter screen 3, the cement material falls to the top surface of the pressing plate 42. As the amount of cement material on the top of the pressing plate 42 increases and the volume becomes larger, the pressing plate 42 moves downward, and the pressing plate 42 compresses the four sets of springs 41, thereby discharging the material through the discharge pipe 2. However, when a large amount of cement material needs to be discharged quickly and falls to the top surface of the pressing plate 42, the descending speed of the pressing plate 42 is accelerated, so that the pressing plate 42 exposes the diverter pipe 43. The diverter pipe 43) is staggered with the discharge pipe 2), and the diverter pipe 43) is higher than the height of the discharge pipe 2), which is convenient for quick discharging. The pressing plate 42 descends to expose the diverter pipe 43, which increases the discharge channel, so that the material can be discharged from the discharge pipe 2 and the diverter pipe 43 at the same time, meeting the discharge speed requirements of different production stages and improving the flexibility and adaptability of the equipment.
