Abstract
Description
Technical Field
[0001] This utility model relates to the field of material production technology in the cement and mining industries, and in particular to a material discharge chute for preventing material blockage. Background Technology
[0002] In cement production and the mining industry, materials are typically conveyed by conveyor belts to a chute for further processing. Materials come in three forms: lumps, small particles, and powder. Due to environmental influences, powdered materials often contain moisture, leading to material accumulation at the four corners of the chute. This causes the discharge hopper to shrink, resulting in large pieces of material getting stuck and causing blockages. Continuing to convey material will cause it to overflow around the conveyor equipment, potentially damaging it and requiring a production shutdown for cleaning.
[0003] To prevent material blockage, Chinese Utility Model Patent Application No. 2015201102021 discloses an anti-blocking structure for a feeding chute. This structure includes an anti-blocking component with a photoelectric switch. When the feeding chute becomes blocked, the photoelectric switch immediately cuts off the power to the conveyor belt's drive motor, stopping the conveyor belt from transporting material. At this point, employees can then clear the blocked feeding chute. Chinese Utility Model Patent Application No. 2023206795204 discloses a novel anti-blocking chute device. In use, a small feeding channel is designed on the side of the feeding chute. When the feeding chute becomes blocked, material automatically flows into the small channel, opening the dust cover, triggering a proximity sensor, and subsequently shutting down the relevant conveying equipment. This automatically stops the upstream material conveying equipment, preventing material spillage or equipment damage. It can be seen that the above technology only monitors whether material blockage has occurred. After it occurs, it still relies on manual on-site cleaning with shovels or iron bars, which presents two problems: first, manual cleaning takes time and affects production efficiency; second, manual cleaning faces dust or other risks, and the cleaning work is quite arduous. Utility Model Content
[0004] The purpose of this utility model is to provide a material discharge chute that prevents material blockage. By providing anti-blockage structures at each of the four corners of the chute, and each anti-blockage structure having a cleaning mechanism with a rotating shaft and a paddle, material accumulation at the four corners is avoided through mechanized means, improving cleaning efficiency and eliminating the need for manual cleaning. To achieve the above objective, this utility model provides the following technical solution:
[0005] This utility model provides a material discharge chute for preventing material blockage, including a material discharge chute body and anti-blockage structures provided at the four corners of its inner wall. Each of the anti-blockage structures includes at least one material clearing mechanism, which includes:
[0006] A rotating shaft is arranged along the corner of the feeding chute body from its top to its bottom, and the rotating shaft is equipped with a first power to drive its reciprocating rotation.
[0007] Several paddles are arranged at intervals on the rotating shaft and move with it, the paddles being arranged along the generatrix of the rotating shaft.
[0008] As a further technical solution, each of the anti-blocking material structures includes two material clearing mechanisms, which are respectively arranged on both sides of the corner of the material discharge chute body.
[0009] As a further technical solution, the paddles on the two rotating shafts belonging to the same anti-clogging material structure are arranged in an alternating manner.
[0010] As a further technical solution, the rotating shaft is also equipped with a second power source to drive its up-and-down reciprocating motion.
[0011] As a further technical solution, the second power source is connected to the material feeding chute body by setting a fixed frame, and a connecting plate is installed on the execution end of the second power source, with the first power source mounted on the connecting plate.
[0012] As a further technical solution, the first power source is an electric motor, and the second power source is an electric actuator.
[0013] As a further technical solution, the top position of one of the material clearing mechanisms belonging to the same anti-clogging material structure is higher than that of the other.
[0014] As a further technical solution, a support seat is provided on the inner wall of the feeding chute body, and the support seat is in sliding and rotating fit with the rotating shaft.
[0015] As a further technical solution, a coupling is provided between the first power source and the rotating shaft.
[0016] The beneficial effects of this utility model are as follows:
[0017] (1) The present invention has anti-blocking structures at the four corners of the feeding chute, and each anti-blocking structure has a cleaning mechanism with a rotating shaft and a paddle.

Detailed Implementation
[0026] The technical solutions in the typical embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0027] like Figure 1 and Figure 2As shown, this embodiment provides a material discharge chute for preventing material blockage, including a material discharge chute body 100 and anti-blocking structures provided at the four corners of its inner wall. The material discharge chute body 100 has a square top inlet and a square bottom outlet 110, forming a top-larger, bottom-smaller structure. During manufacturing, the inner wall forms four corners, where material accumulation occurs. Since the material discharge chute body 100 is a structure already in the prior art, only the above brief description is provided here.
[0028] The four corners of the feeding chute body 100 are respectively provided with anti-blocking structures: a first anti-blocking structure 200, a second anti-blocking structure 300, a third anti-blocking structure 400, and a fourth anti-blocking structure 500. The four anti-blocking structures are the same, and this embodiment will only describe the first anti-blocking structure 200 in detail.
[0029] like Figure 2 As shown, each anti-clogging structure includes at least one cleaning mechanism. It is easy to understand that the function of the cleaning mechanism is to remove accumulated material or prevent material accumulation. If material has already accumulated, the cleaning mechanism can be used for cleaning; additionally, the cleaning mechanism can also be kept open to prevent material accumulation.
[0030] In this embodiment, each anti-blocking material structure includes two material clearing mechanisms, specifically a first material clearing mechanism 210 and a second material clearing mechanism 220, which are respectively located on both sides of the corner of the material discharge chute body 100.
[0031] like Figure 3 and Figure 4 As shown, the material clearing mechanism includes a rotating shaft, a lever, and a power drive for the rotating shaft. The rotating shaft extends from the top to the bottom of the material chute body 100, and the rotating shaft is equipped with a first power drive to reciprocate.
[0032] Specifically, the first cleaning mechanism 210 includes a first rotating shaft 215, a plurality of first paddles 217 disposed on the first rotating shaft 215, and a first power source for driving the first rotating shaft 215 to rotate. In this embodiment, the first power source is a motor, specifically a first motor 213, which is located at the top of the first rotating shaft 215 and connected by a first coupling 214. The first rotating shaft 215 can rotate back and forth repeatedly under the drive of the first motor 213. In the initial state, the first paddles 217 are parallel to or slightly inclined to the same side wall of the discharge chute body 100 (the two cleaning mechanisms are respectively installed on both sides of the corner of the discharge chute body 100, and the side where each cleaning mechanism is located is the same side wall, the same below), and rotate to the right by about 90° during cleaning (in a vertical state, such as...). Figure 2 (As shown) After returning to the initial state, this process is repeated to achieve the purpose of cleaning the material.
[0033] The first cleaning mechanism 210 and the second cleaning mechanism 220 have basically the same structure, but they are positioned at different heights. The second cleaning mechanism 220 includes a second rotating shaft 225, several second paddles 227 disposed on the second rotating shaft 225, and a second power source for driving the second rotating shaft 225 to rotate. In this embodiment, the second power source is a motor, specifically a second motor 223, which is located at the top of the second rotating shaft 225 and connected to it by a second coupling 224. The second rotating shaft 225 can rotate back and forth repeatedly under the drive of the second motor 223. In the initial state, the second paddles 227 are parallel to or slightly inclined to the same side wall of the discharge chute body 100. During cleaning, they rotate to the left by about 90° (in a vertical state, such as...) Figure 2 (As shown) After returning to the initial state, this process is repeated to achieve the purpose of cleaning the material.
[0034] Several paddles are spaced apart on the rotating shaft and move with it. In this embodiment, the paddles are rectangular pieces welded to the rotating shaft, and the paddles are oriented along the generatrix of the rotating shaft. All paddles on the same rotating shaft are along the same generatrix. In this embodiment, three first paddles 217 are provided on the first rotating shaft 215, and two second paddles 227 are provided on the second rotating shaft 225. It is understood that in other embodiments, the number of paddles is selected and designed according to actual needs, and is not limited to the number given in this embodiment.
[0035] In this embodiment, anti-blocking structures are provided at each of the four corners of the feeding chute body 100, and each anti-blocking structure has a cleaning mechanism with a rotating shaft and a paddle. The paddle swings with the reciprocating rotation of the rotating shaft, so that the material accumulated in the corner is cleaned or the material can be prevented from accumulating. The mechanical means are used to avoid the accumulation of material in the four corners and improve the cleaning efficiency.
[0036] The paddles on the two rotating shafts, which belong to the same anti-clogging material structure, are arranged in an alternating pattern, such as... Figure 4 As shown, the three first paddles 217 on the first rotating shaft 215 and the two second paddles 227 on the second rotating shaft 225 are arranged alternately, so that the paddle positions on the two rotating shafts are complementary, which can further improve the material cleaning effect.
[0037] like Figure 3 and Figure 4 As shown, the rotating shaft is also equipped with a second power source to drive its reciprocating motion up and down. The second power source is connected to the material chute body 100 via a fixed frame, and a connecting plate is installed at the actuator end of the second power source, with the first power source mounted on the connecting plate. In this embodiment, the second power source is an electric push rod.
[0038] Specifically, such as Figure 3 and Figure 5As shown, the first cleaning mechanism 210 is provided with a first fixed frame 216, which is fixed on the outer wall of the discharge chute body 100. The first fixed frame 216 is used to support the first electric push rod 211. The execution end of the first electric push rod 211, i.e. the push rod, is fixed with a first connecting plate 212. The first connecting plate 212 is connected to the first motor 213. In essence, the first connecting plate 212 serves as a support structure for the first motor 213. When the first electric push rod 211 moves, it can drive the first motor 213 and the first rotating shaft 215 to move up and down synchronously. At this time, it does not affect the first motor 213's drive on the first rotating shaft 215.
[0039] The second cleaning mechanism 220 is provided with a second fixed frame 226, which is fixed on the outer wall of the discharge chute body 100. The second fixed frame 226 is used to support the second electric push rod 221. The execution end of the second electric push rod 221, i.e. the push rod, is fixed with a second connecting plate 222. The second connecting plate 222 is connected to the second motor 223. In essence, the second connecting plate 222 serves as a support structure for the second motor 223. When the second electric push rod 221 moves, it can drive the second motor 223 and the second rotating shaft 225 to move up and down synchronously.
[0040] In this embodiment, the rotating shaft is also equipped with a second power source that enables it to move up and down. During cleaning, the second power source drives the rotating shaft to move up and down alternately, which can clean up the material accumulated between the two cleaning mechanisms at the same time, further improving the cleaning effect.
[0041] In a structure with the same anti-clogging mechanism, the top of one of the cleaning mechanisms is higher than the other to prevent interference between the two cleaning mechanisms during movement. For example, in this embodiment, when the second cleaning mechanism 220 moves upward, it is preferable that it does not interfere with the first cleaning mechanism 210 in its initial state.
[0042] The inner wall of the feeding chute body 100 is provided with a support seat, which is in sliding and rotating fit with the rotating shaft. The first rotating shaft 215 is equipped with the first support seat 218, and the second rotating shaft 225 is equipped with the second support seat 228.
[0043] The working principle of the feeding chute in this embodiment is as follows:
[0044] The anti-blocking structure can activate when blockage is detected, or it can remain activated continuously. During cleaning, the first electric push rod 211 and the second electric push rod 221 drive the rotating shafts of the corresponding cleaning mechanisms to move up and down alternately (the alternating up and down movement clears the material between the two cleaning mechanisms). At the same time, the first motor 213 drives the first rotating shaft 215 to rotate to the left and then return to its original position (repeated action), and the second motor 223 drives the second rotating shaft 225 to rotate to the right and then return to its original position (repeated action), thus clearing the accumulated material at the corner of the discharge chute.
[0045] It should be noted that since the two cleaning mechanisms are located above the corner of the discharge chute, there may be dead corners for cleaning accumulated material between the bottom of the cleaning mechanism and the corner (these dead corners can be cleaned regularly or during the maintenance of the material blockage structure). However, this does not affect the cleaning of most of the accumulated material, thus effectively solving the problem of material blockage.
[0046] In addition, the working mode of the feeding chute in this embodiment is not limited to that given in this embodiment. The electric push rod and the motor are equipped with a controller so that the alternating motion between the two cleaning mechanism shafts and its own rotation can be carried out simultaneously, sequentially, or independently. The speed of the alternating motion and its own rotation can be adjusted.
[0047] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make possible changes and modifications to the technical solution of the present invention by utilizing the methods and techniques disclosed above without departing from the spirit and scope of the present invention. Therefore, any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall fall within the protection scope of the technical solution of the present invention.
