[0027] The driving end of the first motor 4 extends into the discharge pipe 2 and is fixedly connected to the rotating shaft 10 . The rotating shaft 10 extends into the silo 1 and is fixedly connected to the stirring blade 18 .

[0028] In this embodiment, when it is necessary to unload the white corundum, the white corundum will be discharged from the discharge pipe 2, and the first motor 4 will be started at the same time. The first motor 4 drives the half gear 5 to rotate. When the half gear 5 rotates to engage with the rack 6, as the half gear 5 rotates, the rack 6 moves along the sliding connection with the bracket 3, the first spring 7 is compressed, and the rack 6 drives the two support rods 8 to move. The support rod 8 drives the knocking block 9 to move, so that one of the knocking blocks 9 knocks the discharge pipe 2. When the half gear 5 rotates to separate from the rack 6, the rack 6 moves back to its original position under the push of the first spring 7, and the rack 6 drives the two support rods 8 and the knocking block 9 to move back to their original positions, so that the other knocking block 9 knocks the discharge pipe 2. Repeating this operation makes the two knocking blocks 9 alternately knock on the discharge pipe 2, and the discharge pipe 2 vibrates, thereby avoiding blockage.

[0029] More specifically, when the material is discharged from the discharge pipe 2, the first motor 4 is started, so that the two knocking blocks 9 alternately knock the discharge pipe 2, thereby avoiding blockage. When the first motor 4 is started, the first motor 4 drives the rotating shaft 10 to rotate, and the rotating shaft 10 drives the stirring blade 18 to rotate, so that the stirring blade 18 separates the damp and agglomerated white corundum.

[0030] See also Figure 1-5 As an implementation method for screening white corundum: a sieve plate 11 is movably provided in the silo 1, and the sieve plate 11 is movably connected to a rotating rod 22. A plurality of lifting rods 12 are fixedly provided at the lower end of the sieve plate 11. A support cylinder 13 is fixedly provided in the silo 1. The lower end of the lifting rod 12 extends into the support cylinder 13 and is fixedly connected to a lifting ring 14. A second spring 15 is movably sleeved on the outer side of the lifting rod 12 extending into the support cylinder 13. A rotating disk 16 is fixedly provided on the rotating rod 22. A pushing block 17 is fixedly provided on the rotating disk 16. A discharge pipe 19 is fixedly provided on one side of the silo 1.

[0031] Specifically, when the first motor 4 is started, the first motor 4 drives the rotating rod 22 and the rotating disk 16 to rotate, and the rotating disk 16 drives the pushing block 17 to rotate. Since the sieve plate 11 is arranged at an angle, when the pushing block 17 rotates to contact with the sieve plate 11, the sieve plate 11 will be pushed upward as the pushing block 17 rotates. The sieve plate 11 moves upward and drives the lifting rod 12 to move upward at the same time. The lifting rod 12 drives the lifting ring 14 to move, and the second spring 15 is compressed. When the pushing block 17 rotates to separate the sieve plate 11, the sieve plate 11 moves back to its original position under the push of the second spring 15. Such repeated operations cause the sieve plate 11 to vibrate and screen the white corundum separated by the stirring blades 18, intercept the white corundum blocks that are not completely separated by the stirring blades 18, and discharge the white corundum that meets the requirements after passing through the sieve plate 11. After a batch of white corundum is discharged, the discharge pipe 19 can be opened to discharge the white corundum that has not been completely separated, and it can be placed back into the silo 1, and then separated again by the stirring blades 18 in the subsequent unloading process.

[0032] See also Figure 1-5 As an implementation method for controlling the discharge of the silo 1: a guide ring 20 is fixedly provided in the silo 1, a discharge pipe 21 is fixedly provided at the lower end of the guide ring 20, a rotating rod 22 is rotatably provided in the discharge pipe 21, a plurality of discharge plates 23 are fixedly provided on the rotating rod 22, and a second motor 24 is fixedly provided on the outside of the silo 1, a driving end of the second motor 24 extends into the discharge pipe 21 and is fixedly connected to the rotating rod 22.

[0033] Specifically, when unloading, the white corundum in the silo 1 enters the discharge pipe 21 along the guide ring 20, and the second motor 24 is started. The second motor 24 drives the rotating rod 22 to rotate, and the rotating rod 22 drives multiple discharge plates 23 to rotate. Under the rotation of the discharge plates 23, the white corundum is discharged at a uniform speed.

[0034] To sum up, when the overall equipment is in use:

[0035] When the white corundum in the silo 1 needs to be unloaded, the white corundum in the silo 1 enters the discharge pipe 21 along the guide ring 20, and the second motor 24 is started. The second motor 24 drives the rotating rod 22 to rotate, and the rotating rod 22 drives multiple discharge plates 23 to rotate. Under the rotation of the discharge plates 23, the white corundum is discharged at a uniform speed.

[0036] When the agglomerated white corundum in the silo 1 needs to be separated, the unloaded white corundum will fall onto the sieve plate 11, and the first motor 4 is started. The first motor 4 drives the rotating shaft 10 to rotate, and the rotating shaft 10 drives the stirring blade 18 to rotate, so that the stirring blade 18 separates the agglomerated white corundum affected by moisture. When the first motor 4 is started, the first motor 4 drives the rotating rod 22 and the rotating disk 16 to rotate, and the rotating disk 16 drives the pushing block 17 to rotate. Since the sieve plate 11 is inclined, when the pushing block 17 rotates to contact with the sieve plate 11, as the pushing block 1 The rotation of 7 will push the sieve plate 11 upwards, and the sieve plate 11 moves upwards and drives the lifting rod 12 to move upwards. The lifting rod 12 drives the lifting ring 14 to move, and the second spring 15 is compressed. When the push block 17 rotates to separate the sieve plate 11, the sieve plate 11 moves back to its original position under the push of the second spring 15. Such repeated operations make the sieve plate 11 vibrate and screen the white corundum separated by the stirring blade 18, intercept the white corundum blocks that are not completely separated by the stirring blade 18, and discharge the white corundum that meets the requirements after passing through the sieve plate 11. After a batch of white corundum is discharged, the discharge pipe 19 can be opened to discharge the white corundum that is not completely separated, and it can be placed back in the silo 1, and then separated again by the stirring blade 18 in the subsequent unloading process.

[0037] When in the state of preventing the discharge pipe 2 from being blocked, the white corundum will enter the discharge pipe 2 through the sieve plate 11, and then be unloaded. At the same time, the first motor 4 drives the half gear 5 to rotate. When the half gear 5 rotates to engage with the rack 6, as the half gear 5 rotates, the rack 6 moves along the sliding connection with the bracket 3, the first spring 7 is compressed, and the rack 6 drives the two support rods 8 to move, and the support rod 8 drives the knocking block 9 to move, so that one of the knocking blocks 9 knocks the discharge pipe 2. When the half gear 5 rotates to separate from the rack 6, under the push of the first spring 7, the rack 6 moves back to its original position, and the rack 6 drives the two support rods 8 and the knocking block 9 to move back to their original positions, so that the other knocking block 9 knocks the discharge pipe 2. Repeating this operation makes the two knocking blocks 9 alternately knock on the discharge pipe 2, and the discharge pipe 2 vibrates, thereby avoiding blockage. The entire device is controlled by a controller. Since the devices matched with the controller are commonly used devices and belong to existing mature technologies, their electrical connection relationships and specific circuit structures will not be described in detail here.

In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model.
