Description

Technical Field

[0001] This utility model belongs to the field of bucket elevator technology, specifically relating to an automatic anti-blocking device for bucket elevators. Background Technology

[0002] Bucket elevators are vertical material conveying equipment. They have advantages such as simple structure, low maintenance cost, high conveying efficiency, high lifting height, stable operation, and wide application range. Bucket elevators use a series of buckets fixed to a traction chain to transport bulk materials upward in a vertical or near-vertical direction.

[0003] However, in actual use of bucket elevators, especially when transporting powdery or fine granular materials, as the buckets move to a higher position with the chain, the original feed plates are too small and are designed as through plates, causing some material to fall to the bottom of the bucket elevator, resulting in material blockage. When the material blockage is severe, it is difficult to report to the staff in time for handling, which will affect the normal conveying of the buckets passing through the bottom of the bucket elevator. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic anti-blocking device for bucket elevators that can improve upon the aforementioned problems.

[0005] This utility model provides the following technical solution: An automatic anti-blocking device for a bucket elevator includes a bucket elevator body, a drive assembly, a feed inlet, a discharge outlet, and a base. The discharge outlet is located on one side of the top of the bucket elevator body, and the feed inlet is located on one side of the bottom of the bucket elevator body. A drive sprocket, a driven sprocket, and an auxiliary sprocket are installed inside the bucket elevator body. The drive sprocket, driven sprocket, and auxiliary sprocket are meshed with a chain. Multiple buckets are evenly distributed on the chain. A feed plate is provided at the connection between the discharge outlet and the inside of the bucket elevator body. A support plate is provided below the chain, and a support chamber is provided below the support plate. A discharge port is provided at the bottom of the support chamber.

[0006] Furthermore, connecting blocks are provided on both sides of the hopper, and one end of the connecting block is connected to the chain.

[0007] Furthermore, the material passage square hole is through the hopper, the material passage side hole is through the connecting block, and there is a gap between the material passage square hole and the material passage side hole and the hopper and connecting block through which they pass.

[0008] Furthermore, the feed plate is inclined and flush with the lower surface of the discharge port.

[0009] Furthermore, the base is symmetrically installed at the bottom of the bucket elevator body, and a receiving plate is provided between the bases. The receiving plate is located directly below the discharge port, and a weight sensor is installed on the receiving plate. The weight sensor is electrically connected to an external industrial control computer.

[0010] Furthermore, a slide rail is provided on one side of the base, and sliders that are slidably connected to the slide rail are provided on both sides of the receiving plate.

[0011] Furthermore, a discharge hole is provided in the middle of the material support plate, and electric telescopic rods are symmetrically arranged on both sides of the material support plate.

[0012] Furthermore, the inner wall of the material receiving chamber is inclined, and fixed plates are installed on both sides of the top of the material receiving chamber, with electric telescopic rods installed on the fixed plates.

[0013] Furthermore, the drive assembly is installed on one side of the outer wall of the bucket elevator body, and the drive assembly includes a drive motor, a reducer, a coupling, and a drive shaft.

[0014] In summary, compared with the prior art, the above-described technical solution conceived by this utility model can achieve the following beneficial effects: 1) By extending the feed plate, the amount of material that originally fell directly into the bottom of the bucket elevator is reduced. The feed square hole and feed side hole also facilitate the passage of the bucket. Furthermore, some of the material falling on the lower bucket can be carried into the feed plate and into the discharge port, thus avoiding serious material blockage at the bottom of the bucket elevator. 2) The material is transferred from the bottom of the bucket elevator by means of the material receiving plate and the material receiving chamber, so that the material can fall onto the receiving plate. With the help of the weight sensor, when the load value is exceeded, the feedback can be sent to the external industrial control computer to remind the staff to transfer the material on the receiving plate in time.

Detailed Implementation

[0017] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly understand how to practice this utility model. Although this utility model has been described in conjunction with its preferred embodiments, these embodiments are merely illustrative and not intended to limit the scope of this utility model.

[0018] Combined with appendix Figure 1-4 As shown, an automatic anti-blocking device for a bucket elevator includes a bucket elevator body 1, a drive assembly 5, a feed inlet 3, a discharge outlet 2, and a base 4. The discharge outlet 2 is located on one side of the top of the bucket elevator body 1, and the feed inlet 3 is located on one side of the bottom of the bucket elevator body 1. The bucket elevator body 1 is equipped with a drive sprocket 9, a driven sprocket 12, and an auxiliary sprocket 7. The drive sprocket 9, the driven sprocket 12, and the auxiliary sprocket 7 are meshed with a chain 13, and each drive sprocket 9, the driven sprocket 12, and the auxiliary sprocket 7 is paired with the chain 13. Multiple hoppers 10 are evenly distributed on the chain 13. A feed plate 8 is provided at the connection between the discharge outlet 2 and the inside of the bucket elevator body 1. A support plate 14 is provided below the chain 13, and a support chamber 16 is provided below the support plate 14. A discharge outlet 17 is provided at the bottom of the support chamber 16.

[0019] Specifically, the feed plate 8 is provided with a feed square hole 19, and feed side holes 21 are provided on both sides of the feed square hole 19.

[0020] Specifically, connecting blocks 20 are provided on both sides of the hopper 10. One end of the connecting block 20 is connected to the chain 13. The connecting block 20 is fixedly connected to both sides of the hopper 10. The hopper 10 is driven to move within the bucket elevator body 1 through the transmission of the chain 13.

[0021] Specifically, the material passage square hole 19 is passed through the hopper 10, and the material passage side hole 21 is passed through the connecting block 20. A gap of 0.5 to 1 cm is provided between the material passage square hole 19 and the material passage side hole 21 and the hopper 10 and the connecting block 20, respectively, to ensure that the hopper 10 and the connecting block 20 can pass smoothly through the material passage square hole 19 and the material passage side hole 21, respectively.

[0022] Specifically, the feed plate 8 is inclined and flush with the lower surface of the discharge port 2. The end of the feed plate 8 near the drive sprocket 9 is on the same vertical plane as the outlet end of the hopper 10 at the top of the chain 13. This allows most of the material to fall smoothly into the feed plate 8 and enter the discharge port 2 when the hopper 10 is about to tip over. The end of the feed plate 8 near the drive sprocket 9 is lower than the bottom of the drive sprocket 9, thus avoiding interference with the rotation of the drive sprocket 9.

[0023] Specifically, the base 4 is symmetrically installed at the bottom of the bucket elevator body 1, and a receiving plate 6 is provided between the base 4. The receiving plate 6 is located directly below the discharge port 17, and a weight sensor is installed on the receiving plate 6. The weight sensor is electrically connected to an external industrial control computer. The weight sensor is used to weigh the material received on the receiving plate 6. When the weight exceeds the load capacity, it can be fed back to the external industrial control computer to promptly remind the staff to transfer the material on the receiving plate 6.

[0024] Specifically, each side of the base 4 is provided with a slide rail, and both sides of the receiving plate 6 are provided with sliders that are slidably connected to the slide rail, thereby enabling the receiving plate 6 to be pulled out between the bases 4, which facilitates the subsequent transfer of materials.

[0025] Specifically, a discharge hole 11 is provided in the middle of the material support plate 14, and electric telescopic rods 15 are symmetrically arranged on both sides of the material support plate 14. In addition, the material support plate 14 is arc-shaped, that is, some of the material falling on the material support plate 14 can fall into the discharge hole 11. The electric telescopic rods 15 are electrically connected to an external industrial control computer. The electric telescopic rods 15 can control the material support plate 14 to move up and down continuously, which helps the material to fall into the discharge hole 11 quickly.

[0026] Specifically, the inner wall of the material receiving chamber 16 is inclined so that the material can fall quickly into the discharge port 17. Fixed plates 18 are installed on both sides of the top of the material receiving chamber 16, and electric telescopic rods 15 are installed on the fixed plates 18.

[0027] Specifically, the drive assembly 5 is installed on one side of the outer wall of the bucket elevator body 1. The drive assembly 5 includes a drive motor, a reducer, a coupling and a drive shaft. The drive assembly 5 provides power to the drive sprocket 9, thereby driving the driven sprocket 12 and the auxiliary sprocket 7 through the chain 13, so that the buckets 10 on the chain 13 can be transported up and down inside the bucket elevator body 1. In addition, the drive assembly 5 is also electrically connected to an external industrial control machine.

[0028] The following describes the specific working process of the automatic anti-blocking device for bucket elevators: By activating the drive assembly 5, the driving sprocket 9, driven sprocket 12, and auxiliary sprocket 7 are driven by the chain 13 to achieve vertical transport of the hopper 10 inside the bucket elevator body 1. After material is poured into the feed inlet 3, it is transported in conjunction with the hopper 10. When the hopper 10 is at a high position on the chain 13 and is about to tip over, some material is received by the extended feed plate 8 and falls into the discharge outlet 2. When the hopper 10 is fully tipped over, most of the material falls into the feed plate 8 and enters the discharge outlet 2. A small portion of the material falling onto the lower hopper 10 can also be carried into the feed plate 8 and into the discharge outlet 2 through the feed square hole 19. This reduces the amount of material that would otherwise fall directly to the bottom of the bucket elevator, preventing severe material blockage at the bottom of the bucket elevator. In addition, the material receiving plate 14, together with the material receiving chamber 16, enables the transfer of materials falling into the bottom of the bucket elevator, allowing the materials to fall onto the receiving plate 6. With the help of the weight sensor, when the load exceeds the load value, the feedback can be sent to the external industrial control computer to promptly remind the staff to transfer the materials on the receiving plate 6.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any modifications and substitutions based on the technical solutions and utility model concepts provided by the present utility model should be covered within the protection scope of the present utility model.
