Description

Technical Field

[0001] The utility model relates to the technical field of dischargers, in particular to a silo bottom vibration discharger. Background Art

[0002] The vibrating silo bottom unloader is an ideal silo bottom unloading equipment. It is suitable for unloading small particles and powdery silo bottom materials that are prone to arching and bridging. It uses a vibration motor as a vibration source to drive the unloading hopper to vibrate at a high frequency, causing the material in the silo to flow out of the outlet slowly and evenly. It is often used for unloading powdery materials like flour in the food, feed, chemical and pharmaceutical industries.

[0003] In the existing silo bottom discharger, powdered materials can fall evenly into the collecting silo through the movable plate. However, when a large amount of powdered materials enters the middle of the discharge hopper, the materials stop flowing too much during the vibration process and cannot be cleared by themselves. This can easily cause blockage and compaction between the two and at the discharge port below, resulting in poor material discharge and possible non-discharge. Manual clearing is required by staff at a later stage, which greatly reduces the work efficiency of unloading and is inconvenient for people to use. In order to solve the above-mentioned problems, the utility model provides a silo bottom vibrating discharger. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0019] like Figure 1-4 As shown, a silo bottom vibrating discharger proposed in one embodiment of the utility model comprises: a discharge hopper 1, a vibration motor 2 is installed on the outer surface of the discharge hopper 1;

[0020] An annular frame 3, the annular frame 3 is movably mounted on the top of the discharge hopper 1;

[0021] The movable disk 4 is slidably mounted on the inner side of the annular frame 3, and a mounting plate 5 is fixedly mounted on the inner side of the annular frame 3; the movable disk 4 is slidably mounted on the inner side of the annular frame 3 and has a slide groove track, and the bottom line of the slide groove is located above the drive motor 71 and will not contact the drive motor 71.

[0022] The reciprocating component 7 is installed on the mounting plate 5, and is used to drive the movable disk 4 to move reciprocatingly up and down. The reciprocating component 7 includes a driving motor 71 fixedly installed on the top of the mounting plate 5, and a circular plate 72 is fixedly installed on the output end of the driving motor 71. The output end of the driving motor 71 deviates from the center of the circular plate 72, and a support plate 73 is fixedly installed on the inner circumference of the movable disk 4, and the circular plate 72 is in contact with the support plate 73.

[0023] like Figure 2 A plurality of material dividing plates 15 are fixedly installed on the top of the movable disk 4 in a linear array.

[0024] When using the equipment, start the vibration motor 2 to run, pour the material onto the top of the movable disk 4, the material dividing plate 15 can divide the material into multiple portions and evenly drop, the discharge hopper 1 driven by the vibration motor 2 will vibrate accordingly, so that the material can evenly pass through the position between the movable disk 4 and the annular frame 3, when the amount of material unloaded is large or there is a blockage between the two, the drive motor 71 can be started to drive the circular plate 72 to rotate, because the output end of the drive motor 71 is not at the center of the circular plate 72, the circular plate 72 can push the support plate 73 when rotating, thereby driving the movable disk 4 to move upward, thereby pushing the blocked material, and the material becomes loose when the movable disk 4 moves, and the vibration effect of the vibration motor 2 can be used to unblock the position between the two, so that the material can fall and discharge smoothly, avoiding the need for manual dredging by the staff in the later stage, greatly improving the working efficiency of unloading, and facilitating people's use. When the circular plate 72 is away from the support plate 73, the movable disk 4 will automatically fall under its own gravity.

[0025] Therefore, compared with the prior art, the utility model drives the circular plate to rotate through the driving motor, so that when the circular plate rotates, it pushes the supporting plate, thereby driving the movable plate to move upward, thereby pushing the blocked material. When the movable plate moves, the material becomes loose, and the vibration effect of the vibration motor is combined to unblock the position between the two, so that the material can fall and unload smoothly, avoiding the need for manual unblocking by staff at a later stage, greatly improving the unloading efficiency, and making it convenient for people to use.

[0026] like Figure 1 As shown, in some embodiments, the discharge hopper 1 and the annular frame 3 are fixed by long bolts, and the discharge hopper 1 and the annular frame 3 are provided with shock-absorbing springs 8, which are sleeved on the long bolts.

[0027] During the up and down swinging of the discharge hopper, the free vibration of the annular frame 3 can be greatly reduced under the action of the shock-absorbing spring 8, thereby increasing the stability of the device, making the movement smoother during vibration, and improving the vibration effect of the annular frame 3.

[0028] like Figure 1-4 As shown, in some embodiments, the discharge hopper 1 includes an upper discharge hopper 11 and a lower discharge hopper 12 , and a fixing plate 13 is fixedly connected between the upper discharge hopper 11 and the lower discharge hopper 12 .

[0029] A rotating ring 9 is rotatably installed between the upper discharge hopper 11 and the lower discharge hopper 12, and a plurality of stirring plates 10 are fixedly installed in a circular array on the inner circumference of the rotating ring 9. A driving component 14 for driving the rotating ring 9 to rotate is installed on the upper discharge hopper 11.

[0030] The driving assembly 14 includes a rotating motor 141 fixedly mounted on the outer surface of the upper discharge hopper 11 , a rotating tooth 142 is fixedly mounted on the output end of the rotating motor 141 , a gear ring 143 is fixedly mounted on the outer surface of the rotating ring 9 , and the gear ring 143 meshes with the rotating tooth 142 .

[0031] When the material falls after passing through the movable plate 4 and the upper discharge hopper 11 and passes through the lower discharge hopper 12, the rotating motor 141 is started to drive the rotating teeth 142 to rotate. Since the rotating teeth 142 are engaged with the gear ring 143, the rotating ring 9 thereon can be driven to rotate, and then the multiple stirring plates 10 fixed on the inner circumference thereof can be driven to move. At this time, the falling material will be scattered by the stirring plates 10 and fall, making it difficult for it to gather and fall, causing the discharge port of the lower discharge hopper 12 to be blocked, thereby affecting the unloading efficiency of the discharger.

[0032] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
