The size of the rectangular limit shell 7 matches the mounting block 8, and the rectangular limit shell 7 is covered on the outside of the mounting block 8.

[0038] It is worth mentioning that by respectively arranging a rectangular limit shell 7 and a limit roller 9 on the surface of the silo body 3 and the top of the fixed bracket 1, the limit roller 9 can be used to roll in the rectangular limit shell 7 to generate a buffer gap between the fixed bracket 1 and the silo, thereby playing a role in vibration buffering of the silo.

[0039] The supporting mechanism 2 includes two buffer boxes 201 which are arranged opposite to each other and fixed on the surface of the base. The inner wall of the buffer box 201 is fixedly connected with a limit rod 202. The surface sliding sleeve of the limit rod 202 is provided with a support rod 203.

The telescopic end of the damping shock absorber 204 is fixedly connected to the surface of the support rod 203. The damping shock absorber 204 is used to compensate for the horizontal displacement of the support rod 203.

[0040] A sliding through hole matching the limiting rod 202 is provided on the surface of the support rod 203, and the support rod 203 is slidingly connected to the surface of the limiting rod 202 via the sliding through hole. The support rod 203 is slidingly connected to the inner wall of the buffer box 201, and an extension block is fixedly provided on the top of the support rod 203, and one side surface of the extension block is fixedly connected to the silo body 3, and the support rod 203 is fixedly connected to the surface of the silo body 3 via the extension block.

[0041] It is worth mentioning that by providing a supporting mechanism 2 at the bottom of the silo, the damping shock absorber 204 inside the buffer box 201 can be used to buffer the lateral vibration generated by the support rod 203, and the support rod 203 can be buffered and shock-absorbed with the cooperation of the limit rod 202, thereby achieving a certain shock-absorbing effect on the silo.

[0042] A discharge hopper 4 is provided at the bottom of the silo body 3, and a rubber joint sleeve 5 is fixedly connected between the top of the discharge hopper 4 and the silo body 3, and the discharge hopper 4 can move up and down at the bottom of the silo body 3 through the rubber joint sleeve 5. A driving mechanism 6 is fixedly installed on the surface of the fixed bracket 1, and the driving mechanism 6 is used to drive the discharge hopper 4 to vibrate and discharge materials;

[0043] The driving mechanism 6 includes a driving box 601, a fixing sleeve is fixedly connected to the surface of the driving box 601, a fastening bolt is arranged on the surface of the fixing sleeve, and the fixing sleeve is sleeved on the surface of the fixing bracket 1. The driving box 601 is installed on the surface of the fixing bracket 1 through the fixing sleeve and the fastening bolts.

[0044] A driving motor 602 is fixedly installed on the inner wall of the driving box 601, and the output shaft of the driving motor 602 is fixedly connected to the cam top block 603. A linkage plate 604 is fixedly connected to the side of the discharge hopper 4.

The limit block 607 slides up and down on the surface of the guide column 605 through the guide through hole. A support spring 606 is sleeved on the surface of the guide column 605. The top end of the support spring 606 is fixedly connected to the lower surface of the limit block 607, and the bottom end of the support spring 606 is fixedly connected to the upper surface of the linkage plate 604. During the upward movement of the linkage plate 304, the support spring 606 is squeezed, so that the linkage plate 604 is automatically reset by utilizing the reset elastic force of the support spring 606, thereby causing the discharge hopper 4 to produce an up and down reciprocating motion effect.

[0046] It is worth mentioning that by providing a rubber connecting sleeve 5 between the silo body 3 and the discharge hopper 4, a split-type movable connection structure can be formed between the discharge hopper 4 and the silo body 3, so that the discharge hopper 4 can independently vibrate and discharge materials. When the discharge hopper 4 is discharging materials, the driving motor 602 is used to drive the cam top block 603 to rotate, and then repeatedly push the linkage plate 604 upward. The linkage plate 604 drives the discharge hopper 4 to move upward, so that the linkage plate 604 moves on the surface of the guide column 605, and then under the action of the self-gravity of the discharge hopper 4 and the support spring 606, the discharge hopper 4 automatically resets downward to produce an up and down vibration effect, thereby facilitating the discharge of the discharge hopper 4, reducing the lateral vibration of the traditional silo vibrator on the silo, effectively improving the stability of the silo during discharging, and helping to extend the service life.
