Abstract
Description
Technical Field
[0001] This utility model relates to the field of vibrating conveyor technology, and in particular to a material unloading structure for a vibrating conveyor. Background Technology
[0002] Our vibrating conveyor has multiple discharge ports, which supply material to multiple downstream devices. A discharge hopper is welded to the underside of each discharge port, through which material is discharged into the feed inlet of the downstream device. Currently, the discharge hopper is installed at the discharge port by welding. However, this has led to the following problems during long-term use: First, replacing the discharge hopper requires removal using an oxyacetylene torch or cutting machine, resulting in a large workload and impacting maintenance efficiency. Second, when maintenance is needed on the downstream pipe fittings of one of the discharge hoppers, the vibrating conveyor must be shut down for an extended period, causing delays and disrupting production at the downstream equipment.
[0003] To address the aforementioned issues, our technical personnel, based on existing vibrating conveyors, proposed the unloading structure for a vibrating conveyor as described in this application. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a discharge structure for a vibrating conveyor. By fixing guide rails on both sides of the discharge port, and providing grooves on the opposite sides of the two guide rails, and fixing protruding plates on the opposite sides of the upper end of the discharge hopper, the protruding plates on both sides are inserted into the grooves on both sides. The plug-in installation structure facilitates quick installation and removal of the discharge hopper, thereby shortening maintenance time and improving maintenance efficiency.
[0005] To achieve the above objectives, this application provides a discharge structure for a vibrating conveyor, including a material conveying channel of the vibrating conveyor, at least one discharge port at the bottom of the material conveying channel, a discharge hopper installed at the corresponding discharge port at the bottom of the material conveying channel, guide rails fixedly installed on both sides of the bottom of the material conveying channel at the discharge port, grooves respectively provided on opposite sides of the two guide rails, and protruding plates fixedly installed on opposite sides of the upper end of the discharge hopper, with the protruding plates on both sides respectively inserted into the grooves on both sides.
[0006] A limiting structure is installed on the guide rail, which limits the extension plate to be positioned relative to the guide rail.
[0007] The limiting structure includes a limiting screw; the lower side of the guide rail is provided with a plurality of first threaded holes, in which the limiting screw is screwed, and the threaded end of the limiting screw abuts against the lower side of the protruding plate.
[0008] The limiting structure includes a baffle; the end of the guide rail is provided with a second threaded hole, and the threaded end of the screw passes through the mounting hole on the baffle and is screwed into the second threaded hole for fixation.
[0009] A sealing gasket is installed between the top of the protruding plate and the guide rail.
[0010] The unloading hopper has an outwardly extending receiving cavity on one side, and a rotating component is rotatably installed inside the receiving cavity to close the discharge port.
[0011] The rotating component includes a support shaft, an extension plate, and a closing plate. The two ends of the support shaft are rotatably connected to the side walls on both sides of the discharge hopper, and the closing plate is fixed to the support shaft through the extension plate. When the closing plate abuts against the bottom of the material conveying channel, it closes the discharge port.
[0012] Bearing seats are installed on the side walls on both sides of the unloading hopper, and the two ends of the support shaft are connected to the bearing seats on both sides respectively.
[0013] A swing arm is installed at one end of the support shaft located outside the unloading hopper. A telescopic device is hinged to the outer wall of the material conveying channel. A hinge joint is installed at the telescopic end of the telescopic device, and the hinge joint is hinged to the swing arm pivot.
[0014] The sealing plate is also equipped with a blocking plate. When the sealing plate abuts against the bottom of the material conveying channel, the blocking plate is inserted into the discharge port, and the upper side of the blocking plate is flush with the bottom surface of the material conveying channel.
[0015] Compared with the prior art, the above-conceptual technical solution conceived in this application has the following beneficial effects: 1. This utility model uses guide rails fixedly installed on both sides of the discharge port, with grooves on opposite sides of the two guide rails. Extending plates are fixedly installed on opposite sides of the upper end of the discharge hopper, and the extending plates on both sides are inserted into the grooves on both sides. The plug-in installation structure facilitates quick installation and removal of the discharge hopper, thereby shortening maintenance time and improving maintenance efficiency.
[0016] 2. In this utility model, a receiving cavity extending outward is provided on one side of the unloading hopper. A rotating component is rotatably installed inside the receiving cavity to close the discharge port. When the matching pipe at the lower end of the unloading hopper below one of the discharge ports needs maintenance, the corresponding discharge port is closed by the rotating component, which does not affect the discharge of the other discharge ports and has less impact on downstream production.

[0025] To more clearly illustrate the purpose, technical solution, and beneficial effects of this application, a further detailed description of this application is provided below in conjunction with illustrations and specific embodiments. It should be specifically noted that the specific embodiments described below are only for illustrating the technical content of this application and do not constitute a limitation on the scope of protection of this application.
[0026] Regarding the explanation of terminology: In this application, "and / or" is used to describe the relationship between related objects, covering three possible situations: taking "A and / or B" as an example, it can indicate the situation where only A exists, A and B exist simultaneously, or only B exists; the symbol " / " indicates the "or" relationship between related objects, such as "A / B" which refers to A or B.
[0027] Regarding the description of the embodiments: The terms "exemplary" and "for example" appearing in this application are only used to illustrate the technical solutions through specific examples. It should be particularly emphasized that any implementation method or design scheme marked as "exemplary" or "for example" should not be construed as having an advantage over other solutions. Such expressions are only used to present the technical concepts more intuitively.
[0028] Example 1: See Figure 1This embodiment provides a discharge structure for a vibrating conveyor, including a material conveying channel 10 of the vibrating conveyor. At least one discharge port 11 is provided at the bottom of the material conveying channel 10, and a discharge hopper 20 is installed at the bottom of the material conveying channel 10 at the position corresponding to the discharge port 11. Guide rails 12 are welded and fixed to the bottom of the material conveying channel 10 on both sides of the discharge port 11. An extension plate 21 is welded to the upper end of the discharge hopper 20 on both opposite sides, and the extension plates 21 on both sides are respectively inserted into the grooves 13 on both sides.
[0029] This utility model uses guide rails 12 fixedly installed on both sides of the discharge port 11. The two guide rails 12 are respectively provided with grooves 13 on opposite sides. The extension plates 21 are respectively fixed on opposite sides of the upper end of the discharge hopper 20. The extension plates 21 on both sides are respectively inserted into the grooves 13 on both sides. The plug-in installation structure facilitates quick installation and removal of the discharge hopper 20, thereby improving maintenance efficiency.
[0030] Further, see Figure 1 A limiting structure is installed on the guide rail 12. The limiting structure limits the extension plate 21 to the guide rail 12 to prevent the unloading hopper 20 from detaching from the guide rail 12 during production.
[0031] In one of the solutions, see Figure 1 The limiting structure includes a limiting screw 15. Specifically, a plurality of first threaded holes 14 are provided on the lower side of the guide rail 12, and the limiting screw 15 is screwed into the first threaded holes 14. The threaded end of the limiting screw 15 abuts against the lower side of the protruding plate 21, thereby connecting the unloading hopper 20 to the guide rail 12. See also Figure 3 Each guide rail 12 has 5 first threaded holes 14.
[0032] In another option, see Figure 3 The limiting structure includes a baffle 18, which closes the end of the groove 13 to prevent the unloading hopper 20 from disengaging from the guide rail 12.
[0033] Specifically, the end of the guide rail 12 is provided with a second threaded hole 17, and the threaded end of the screw passes through the mounting hole on the baffle 18 and is screwed into the second threaded hole 17 for fixation.
[0034] In practical implementation, when the groove 13 passes through both ends of the guide rail 12, baffles 18 need to be installed at both ends of the guide rail 12; when one end of the groove 13 inside the guide rail 12 is closed and the other side is open, only the baffle 18 needs to be installed on the open side. See Figure 2 , 3 In this embodiment, the groove 13 is preferably closed at one end and open at the other end.
[0035] Further, see Figure 1 , 2A sealing gasket 16 is installed between the top of the protruding plate 21 and the guide rail 12 to improve the sealing between the protruding plate 21 and the guide rail 12. The sealing gasket 16 can be a rubber gasket.
[0036] Example 2: Based on Example 1, see Figure 1 , 4 5. A receiving cavity 22 extending outward is provided on one side of the unloading hopper 20. A rotating component 30 is rotatably installed in the receiving cavity 22. The rotating component 30 is used to close the discharge port 11. When the matching pipe at the lower end of the unloading hopper 20 below one of the discharge ports 11 needs maintenance, the corresponding discharge port 11 is closed by the rotating component 30, which does not affect the discharge of the other discharge ports 11 and has less impact on downstream production.
[0037] Specifically, see Figure 4 , 5 The rotating component 30 includes a support shaft 31, an extension plate 32, and a closing plate 33. The two ends of the support shaft 31 are rotatably connected to the side walls on both sides of the discharge hopper 20. The closing plate 33 is welded to the support shaft 31 through the extension plate 32. When the closing plate 33 abuts against the bottom of the material conveying channel 10, it closes the discharge port 11.
[0038] Further, see Figure 5 Bearing seats 35 are installed on the side walls of the unloading hopper 20, and the two ends of the support shaft 31 are connected to the bearing seats 35 on both sides.
[0039] See Figure 4 , 5 A swing arm 36 is fixedly installed at one end of the support shaft 31 located outside the unloading hopper 20. By driving the swing arm 36 to swing, the closing plate 33 is rotated from the front. (See also...) Figure 1 , 6 A telescopic device 40 is hinged to the outer wall of the material conveying channel 10. A hinge joint 41 is installed at the telescopic end of the telescopic device 40, and the hinge joint 41 is pivotally hinged to the swing rod 36. The telescopic device 40 extends and retracts, thereby driving the closed plate 33 to rotate.
[0040] In this embodiment, the telescopic device 40 can be one of a hydraulic cylinder, a pneumatic cylinder, or an electric push rod. The hinge joint 41 is a Y-shaped joint.
[0041] In the preferred solution, see Figure 1 , 6 The telescopic device 40 is a cylinder with a central trunnion structure, which is rotatably mounted on a double-eared hinge seat 42. A connecting plate is fixed to the bottom of the hinge seat 42 and welded to the outer wall of the material conveying channel 10.
[0042] Further, see Figure 4A blocking plate 34 is also installed on the sealing plate 33. When the sealing plate 33 abuts against the bottom of the material conveying channel 10, the blocking plate 34 is inserted into the discharge port 11, and the upper side of the blocking plate 34 is flush with the bottom surface of the material conveying channel 10. The length and width of the blocking plate 34 are smaller than the length and width of the sealing plate 33. When the sealing plate 33 abuts against the bottom of the material conveying channel 10, the upper side of the blocking plate 34 is flush with the bottom surface of the material conveying channel 10, which facilitates the downstream movement of materials in the material conveying channel 10.
[0043] It should be noted that the upper side of the blocking plate 34 in this application is flush with the bottom surface inside the material conveying channel 10, and there can be a certain error. For example, within ±1mm.
[0044] The working principle or process of this utility model: See Figure 1 When the unloading hopper 20 needs to be replaced, i.e. during major overhaul, first remove the hinge pivot of the hinge joint 41 and the swing arm 36, then remove the baffle 18 and unscrew the limit screw 15, so that the unloading hopper 20 can be removed more quickly and the installation of a new unloading hopper 20 is also more convenient. The whole process does not require oxygen cutting and welding.
[0045] When maintenance is required on the downstream fittings of one of the discharge hoppers 20, the telescopic end of the telescopic device 40 can be extended without stopping the vibrating conveyor. This drives the closing plate 33 to rotate. When the closing plate 33 abuts against the bottom of the material conveying channel 10, the blocking plate 34 inserts into the discharge port 11, sealing the discharge port 11 without affecting the production of downstream equipment at other discharge ports 11. The vibrating conveyor can then be stopped. After the downstream fittings are removed from the lower end of the discharge hopper 20, the vibrating conveyor can be restarted, reducing downtime. Once the downstream fittings are repaired, the conveyor can be stopped and reinstalled.
[0046] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
