Description

Technical Field

[0001] This utility model relates to the field of conveyor anti-deviation technology, specifically an anti-deviation device for belt conveyors in mineral processing plants. Background Technology

[0002] A conveyor consists of a frame, rotating rollers, and a conveyor belt. In use, the rotating rollers drive the conveyor belt, and the items to be transported are placed on the conveyor belt, which then moves the items.

[0003] When a conveyor belt is running, if the joints of the conveyor belt are not aligned, forming a "trumpet mouth" or local warping, or if the belt body quality is uneven, with inconsistent thickness and hardness during production, or if there is long-term wear on one side, resulting in tension differences on both sides, a lateral force will be generated during operation, causing the conveyor belt to run off-center. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes an anti-deviation device for belt conveyors in mineral processing plants, which can adjust the tension on both sides of the conveyor belt to prevent it from deviating from its intended path.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a belt conveyor anti-deviation device for a mineral processing plant, comprising a frame, a conveyor belt, and a rotating roller. The rotating roller includes a roller body, and a polygonal groove is provided inside the roller body. A polygonal rod is slidably connected to the inner wall of the polygonal groove, and a rotating shaft is fixedly connected to both ends of the polygonal rod. The rotating shaft is rotatably connected to the frame body. A conical groove communicating with the polygonal groove is provided at both ends of the roller body, and an expansion top that can move back and forth is provided in the conical groove.

[0006] Preferably, the expansion top component includes a conical block disposed in a conical groove, and the conical block is slidably sleeved on the outer wall of a polygonal rod. A long groove is opened on one side wall of the polygonal rod, and a connecting block is slidably connected to the inner wall of the long groove. The connecting block is fixedly connected to the conical block. One end of one of the rotating shafts is provided with a clearance groove, and a top component is disposed in the clearance groove.

[0007] Preferably, the top member includes a bolt disposed in the relief groove, and the bolt is threadedly connected to the polygonal rod. One end of the bolt passes through the polygonal rod and is rotatably connected to the connecting block. A connecting rod is disposed between the two connecting blocks. The connecting rod is located in the long groove, and both ends of the connecting rod are fixedly connected to the two connecting blocks respectively.

[0008] Preferably, multiple strip grooves are provided at both ends of the roller body, and the multiple strip grooves are distributed at equal intervals.

[0009] Preferably, the bottom of the conical groove has an annular groove.

[0010] Preferably, a sealing cap is provided at one end of the relief groove.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention, by setting a conical groove and using an expansion top piece in conjunction, allows the expansion top piece to expand one side of the roller when the conveyor belt deviates to one side, thereby adjusting the tension on one side of the conveyor belt, stabilizing the tension on both sides of the conveyor belt, and thus preventing the conveyor belt from deviating.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1-4 A device for preventing belt misalignment in a mineral processing plant belt conveyor includes a frame 1, a conveyor belt 2, and a rotating roller 3. The rotating roller 3 includes a roller body 301, and a polygonal groove is provided inside the roller body 301. A polygonal rod 302 is slidably connected to the inner wall of the polygonal groove, and a rotating shaft 303 is fixedly connected to both ends of the polygonal rod 302. The rotating shaft 303 is rotatably connected to the frame 1. A conical groove 304 communicating with the polygonal groove is provided at both ends of the roller body 301, and an expansion top that can move back and forth is provided in the conical groove 304.

[0020] As can be seen from the above structure, by setting the conical groove 304 and using it in conjunction with the expansion top, when the conveyor belt 2 deviates to one side of the rotating roller 3, the expansion top can be used to expand one side of the rotating roller 3, thereby adjusting the tension on one side of the conveyor belt 2, stabilizing the tension on both sides of the conveyor belt 2, and thus preventing the conveyor belt 2 from deviating.

[0021] See Figure 3 and Figure 4 The expansion top component includes a conical block 4 disposed in a conical groove 304, and the conical block 4 is slidably sleeved on the outer wall of a polygonal rod 302. A long groove 5 is provided on one side wall of the polygonal rod 302, and a connecting block 6 is slidably connected to the inner wall of the long groove 5. The connecting block 6 is fixedly connected to the conical block 4. A relief groove 7 is provided at one end of one of the rotating shafts 303, and a top component is disposed in the relief groove 7. By setting the conical block 4, when the conical block 4 is moved so that the conical block 4 is tightly abutted against the conical groove 304, one end of the roller body 301 can be expanded.

[0022] See Figure 3 and Figure 4 The top component includes a bolt 8 disposed within the relief groove 7, and the bolt 8 is threadedly connected to the polygonal rod 302. One end of the bolt 8 passes through the polygonal rod 302 and is rotatably connected to the connecting block 6. It should be noted that this rotatable connection is a bearing connection, with the outer sleeve of the bearing fixed to the connecting block 6. One end of the bolt 8 is fixedly connected to the inner sleeve of the bearing. A connecting rod 9 is disposed between the two connecting blocks 6, located within the elongated groove 5, and both ends of the connecting rod 9 are fixedly connected to the two connecting blocks 6 respectively. By using the bolt 8, during adjustment, rotating the bolt 8 allows the bolt 8 to push the connecting block 6 against one of the connecting blocks. A conical block 4 is formed, which causes one of the conical blocks 4 to move. The moving conical block 4 abuts tightly against the conical groove 304, expanding one end of the roller body 301. The other conical block 4 can be connected by a connecting rod 9. When one conical block 4 expands one end of the roller body 301, the other conical block 4 also moves. The moving other conical block 4 causes the other conical groove 304 to lose support. This causes the other end of the roller body 301 to lose support and its deformation to return to normal. In this way, one end of the roller body 301 becomes larger and the other end becomes smaller, so that the roller body 301 adjusts the tension on both sides of the conveyor belt 2 to prevent the conveyor belt 2 from running off-center.

[0023] See Figure 2 , Figure 3 and Figure 4 Multiple strip grooves 10 are provided at both ends of the roller body 301, and the multiple strip grooves 10 are equally distributed; by providing the strip grooves 10, the deformation of one end of the roller body 301 can be facilitated.

[0024] See Figure 3 and Figure 4 The bottom of the conical groove 304 is provided with an annular groove 11; by providing the annular groove 11, the strength of the roller body 301 can be reduced, which further facilitates the deformation of one end of the roller body 301.

[0025] See Figure 3A sealing cap 12 is provided at one end of the relief groove 7; by providing the sealing cap 12, one end of the relief groove 7 can be sealed, thereby preventing impurities from the outer cover from entering the relief groove 7.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
