Description

Technical Field

[0001] The utility model relates to a novel storage bin for continuous material conveying, belonging to the field of material conveying. Background Art

[0002] With the rapid development of material conveying and automatic conveying technologies, the speed and efficiency of material sorting and conveying have been significantly improved. At present, material conveying generally adopts a storage bin connected with various conveying line bodies (such as belt conveyors and roller conveyors) to temporarily store materials according to the conveying speed or production line requirements.

[0003] Due to the complexity of material varieties and the limitation of the internal space of the storage bin, combined with the physical properties of the materials themselves, a bridging phenomenon usually occurs inside the storage bin, that is, local materials support and block each other and are connected into a "block", resulting in the inability of the materials to be normally conveyed or fall. There is no effective solution in the prior art. Usually, tools are used by workers to intermittently stir or manually handle after stopping the vehicle. Such a processing method by stopping the feeding is time-consuming and laborious, seriously affecting the overall conveying and production efficiency.

[0004] In view of this, this patent application is specifically proposed. Summary of the Utility Model

[0005] This application proposes a storage bin with an anti-bridging mechanism, aiming to solve the problems and deficiencies existing in the above-mentioned prior art, and proposes a rotating shaft mechanism that performs simultaneous circumferential cutting at multiple positions during the conveying process to prevent the occurrence of bridging phenomena, so as to achieve continuous feeding operation while meeting the temporary storage and transfer of materials, thereby significantly improving the conveying and production efficiency.

[0006] To achieve the above design purpose, the storage bin with an anti-bridging mechanism includes a storage bin with a feed inlet and a discharge outlet. A driving shaft is horizontally arranged through the two side plates of the storage bin. Two sets of cylinder driving components are symmetrically arranged outside the storage bin, which are respectively connected to the two ends of the driving shaft to drive the vertical reciprocating movement of the driving shaft up and down, and a set of motor components for axially driving the rotation of the driving shaft; multiple sets of stirring teeth are arranged on the driving shaft, which are arranged in a circumferentially staggered manner and at intervals along the axis.

[0007] Furthermore, a set of vertically extending long slots are respectively arranged on the two side plates of the storage bin. The two ends of the driving shaft can axially pass through the long slots and can move up and down along the long slots; two sets of rack mounting seats are symmetrically arranged on both sides of each long slot, and a cylinder mounting seat is installed vertically above the long slot.

[0008] Further, each set of cylinder drive assemblies includes a cylinder. The base of the cylinder is fixedly installed on the side plate of the silo through a cylinder mounting seat, and the drive end of the cylinder is fixedly connected to a connecting seat. A rotating motor is installed on a set of connecting seats on one side of the silo. The output end of the rotating motor is coaxially drivingly connected to one end of a drive shaft. Both ends of the drive shaft penetrate through the two side plates of the silo and are respectively axially connected to the two sets of connecting seats.

[0009] Further, two sets of gear bearing assemblies are sleeved on the drive shaft. The bearing part is sleeved between the drive shaft and the gear part, and a rack meshing with the gear part is fixedly installed on a rack mounting seat on the side plate of the silo.

[0010] Further, a limiting plate is sleeved outside the gear bearing assemblies on the drive shaft.

[0011] Further, brush-type sealing plates are respectively installed on both sides of each long slot 11 inside the two side plates of the silo.

[0012] As described above, the storage silo with an anti-bridging mechanism proposed in this application can effectively ensure that while continuously feeding, the connection between the agglomerated materials is timely interrupted, so as to realize continuous and uninterrupted feeding to the downstream device, and completely solve the problems such as unsmooth conveying caused by material bridging. The whole device does not require manual intervention and parking treatment, saving labor costs and improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] To further elaborate on the technical means adopted by the present application to achieve the intended design purpose, the following relatively preferred implementation solutions are proposed in conjunction with the drawings.

[0020] Specific details are set forth in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0021] Example 1, as Figures 1 to 5 As shown, the storage bin with an anti-bridging mechanism described in the present application includes a bin 1 with a feed inlet and a discharge outlet. A driving shaft 2 is horizontally and axially arranged through the two side plates of the bin 1. On the outside of the bin 1, two groups of cylinder driving components 3 are symmetrically arranged, which are respectively connected to both ends of the driving shaft 2 to drive the vertical reciprocating lifting of the driving shaft 2, and a motor component 4 for axially driving the rotation of the driving shaft 2.

[0022] Wherein, a group of vertically extending long slots 11 are respectively arranged on the two side plates of the bin 1. The two ends of the driving shaft 2 can respectively axially pass through the long slots 11 and can move up and down along the long slots 11. On both sides of each long slot 11, two groups of rack mounting seats 12 are symmetrically arranged. In addition, a cylinder mounting seat 13 is installed vertically above the long slot 11.

[0023] A plurality of groups of stirring teeth 21 are arranged on the driving shaft 2 in a circumferentially staggered and axially spaced manner.

[0024] Each group of cylinder driving components 3 includes a cylinder 31. The base of the cylinder 31 is fixedly installed on the side plate of the bin 1 through the cylinder mounting seat 13, and the driving end of the cylinder 31 is fixedly connected to the connecting seat 32.

[0025] A rotating motor 33 is installed on a group of connecting seats 32 on one side of the bin 1. The output end of the rotating motor 33 is coaxially driven and connected to one end of the driving shaft 2. The two ends of the driving shaft 2 penetrate through the two side plates of the bin 1 and are respectively axially connected to the two groups of connecting seats 32. Driven by the rotating motor 33, the driving shaft 2 can continuously rotate horizontally between the two groups of connecting seats 32, so that the "bridges" formed among the materials are simultaneously agitated and broken by several groups of stirring teeth 21 within a certain range to ensure the smoothness of the material discharging process inside the bin 1.

[0026] Two groups of gear bearing assemblies 22 are sleeved on the driving shaft 2. The bearing part is sleeved between the driving shaft 2 and the gear part. The rack 23 meshed with the gear part is installed and fixed on the rack mounting seat 12 on the side plate of the bin 1. Driven by the two groups of cylinders 31 together, during the vertical reciprocating lifting of the driving shaft 2, by means of the meshing transmission between the gear and the rack, the driving shaft 2 runs along the vertical track provided by the long slot 11 on the side plate of the bin 1, so as to realize the rotation of the driving shaft 2 itself and at the same time carry out the operation process of agitating and breaking the "bridges" in a larger range through the lifting movement.

[0027] To prevent lateral displacement when the gear bearing assembly 22 moves up and down along the rack 23, a limiting plate 24 is sleeved outside the gear bearing assembly 22 on the drive shaft 2. The two groups of limiting plates 24 respectively provide horizontal limiting to the adjacent gear bearing assembly 22 from one side, so that the gear bearing assembly 22 can only move up and down along the rack 23.

[0028] To prevent materials from leaking out of the silo 1 through the long slots 11, brush-type sealing plates 14 can be installed on both sides of each long slot 11 inside the two side plates of the silo 1; while the drive shaft 2 rotates, the long slots 11 are closed by the brush parts on the brush-type sealing plates 14.

[0029] Based on the above structural design of the storage silo with an anti-bridging mechanism, the present application can implement the following anti-bridging operation process:

[0030] Step 1: Pass both ends of the drive shaft 2 through the two side plates of the silo 1 and axially install them on the connecting seat 32 to complete the installation connection with the cylinder drive assembly 3.

[0031] At the same time, install the brush-type sealing plates 14 inside the two side plates of the silo 1 to close the long slots 11 and prevent materials from leaking out.

[0032] Step 2: Install the rack 23 on the rack mounting seats 12 on the two side plates of the silo 1, and sequentially install the gear bearing assembly 22 and the limiting plate 24 on both sides of the drive shaft 2; at the same time, connect the drive end of the drive shaft 2 to the rotating motor 33, so that the drive shaft 2 can rotate along its own axis to break the material bridge.

[0033] Step 3: The cylinder 31 reciprocates up and down to drive the connecting seat 32 to drive the drive shaft 2 to move up and down while rotating, so as to break the bridges of materials at different heights inside the silo 1.

[0034] In summary, the embodiments given in the accompanying drawings are only the preferred solutions to achieve the purpose of the present invention. Those skilled in the art can get inspiration from this and directly derive other alternative structures that conform to the design concept of the present invention. The other structural features obtained thereby should also fall within the scope of the solutions described in the present invention.
