Technical Field
[0001] This utility model relates to the field of hopper cleaning structure technology, and in particular to a conical hopper cleaning device. Background Technology
[0002] Currently, conical hoppers are widely used in powder and granular material storage and conveying systems, particularly in intermediate silos, buffer silos, and unloading silos. However, due to material characteristics (such as high moisture content, high viscosity, and fine particle size) or structural design, materials in conical hoppers are prone to adhesion, accumulation, and bridging, leading to poor discharge or even blockages, severely impacting production continuity and system stability. Traditional cleaning methods primarily rely on manual tapping, mechanical vibration, or pneumatic arch breaking, which have the following shortcomings: ① Manual cleaning requires machine shutdown, which is labor-intensive, inefficient, and poses safety hazards; ② Mechanical vibration devices have limited cleaning effect, making it difficult to completely remove highly adhesive materials, and long-term vibration can easily lead to structural fatigue; ③ The pneumatic arch-breaking device has high energy consumption and noise, and is not targeted at the accumulation location, resulting in incomplete material removal. Utility Model Content
[0003] The purpose of this utility model is to provide a conical hopper cleaning device. By setting a reciprocating arc-shaped cleaning plate inside the hopper, combined with the top slide rail and traction drive system, the device can mechanically scrape off the material adhering to the inner wall of the hopper. The device can operate automatically without stopping the machine, and it cleans the material thoroughly. It has a simple structure, reliable operation, and effectively improves the material flowability and the level of system automation.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A conical hopper cleaning device is installed on the hopper body and includes one or more arc-shaped cleaning plates. The arc-shaped cleaning plates are attached to the inner circumferential surface of the hopper body. An upper slide rail and a middle slide rail are respectively connected to the hopper body. The upper and lower ends of the arc-shaped cleaning plates are respectively provided with upper guide grooves and lower guide grooves that correspond to and are adapted to the upper slide rail and the middle slide rail. A moving drive component that drives the arc-shaped cleaning plates to rotate around the inner circumference of the hopper body is also connected to the hopper body.
[0005] By adopting the above technical solution, the arc-shaped cleaning plate is limited and guided by the slide rail and guide groove to realize reciprocating motion inside the hopper, so as to mechanically scrape off the material adhering to the inner wall of the hopper. It can run automatically without stopping the machine, and the cleaning is thorough, the structure is simple and the operation is reliable.
[0006] Furthermore, the moving drive component includes traction steel wire ropes connected to both sides of the arc-shaped clearing plate, and the two traction steel wire ropes are connected to the winch.
[0007] By adopting the above technical solution, the winch is connected to both sides of the arc-shaped cleaning plate through traction steel wire ropes, so as to realize the reciprocating movement of the arc-shaped cleaning plate under the traction of the traction steel wire ropes on both sides.
[0008] Furthermore, two sets of traction wire ropes are wound on the drum of the winch, which are connected to the arc-shaped cleaning plate from both sides of the winch. The winch releases one set of traction wire ropes while the other set of traction wire ropes is retracted.
[0009] By adopting the above technical solution, one winch can pull two sets of traction wire ropes, so that one set of traction wire ropes is released while the other set of traction wire ropes is retracted, realizing the reciprocating motion of the arc-shaped cleaning plate.
[0010] Furthermore, the upper slide rail is connected to the upper end of the hopper body.
[0011] By adopting the above technical solution, the impact of the slide rail on the feeding is reduced, and the processing of the hopper body is facilitated.
[0012] Furthermore, the traction wire rope abuts against the outer periphery of the upper slide rail.
[0013] By adopting the above technical solution, the traction rope transmits the traction force of the winch, thereby driving the arc-shaped cleaning plate to rotate around the inner circumference of the hopper body.
[0014] Furthermore, pull rods are connected to both sides of the upper end of the arc-shaped cleaning plate, and corresponding traction steel wire ropes are connected to the outer ends of the pull rods.
[0015] By adopting the above technical solution, it is convenient to connect the arc-shaped cleaning plate and the traction wire rope.
[0016] Furthermore, the upper end of the arc-shaped cleaning plate extends outward in a contacting part, which abuts against the upper end of the hopper body.
[0017] By adopting the above technical solution, the rotational stability of the arc-shaped cleaning plate is improved, its impact on the feeding is reduced, and it is convenient to process and connect the traction wire rope.
[0018] Furthermore, the abutting part is arc-shaped or circular, and an upper guide groove is formed on the lower side of the abutting part.

[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. These embodiments do not constitute a limitation on this utility model. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.
[0025] A conical hopper cleaning device, such as Figure 1 and Figure 2 As shown, the hopper body 1 is installed with one or more arc-shaped cleaning plates 2. The arc-shaped cleaning plates 2 are arranged inside the hopper body 1, and their arc-shaped contours match the inner wall of the hopper, so that the arc-shaped cleaning plates 2 are attached to the inner circumferential surface of the hopper body 1. The hopper body 1 is also connected to a moving drive component that drives the arc-shaped cleaning plates 2 to rotate around the inner circumference of the hopper body 1, controlling the reciprocating motion of the arc-shaped cleaning plates 2 inside the hopper to mechanically scrape off the material adhering to the inner wall of the hopper. In this embodiment, the moving drive component includes traction steel wire ropes 6 connected to both sides of the arc-shaped cleaning plate 2. The two traction steel wire ropes 6 are connected to the winch 5 to realize the reciprocating movement of the arc-shaped cleaning plate 2 under the traction of the traction steel wire ropes 6 on both sides. It can also be a toothed ring connected to the upper end of the arc-shaped cleaning plate 2 and driven to rotate by means of motors and gears.
[0026] like Figure 1 and Figure 2 As shown, in order to reduce the number of winches 5, two sets of traction steel wire ropes 6 are wound on the drum of the winch 5, and their winding directions are opposite (the two sets of traction steel wire ropes 6 can also be the two ends of the same traction steel wire rope 6, with the middle part fixed on the drum of the winch 5 and the two ends connected to the corresponding sides of the arc-shaped cleaning plate 2 from both sides). They are connected to the arc-shaped cleaning plate 2 from both sides of the winch 5 respectively. When the winch 5 drives one set of traction steel wire ropes 6 to release, the other set of traction steel wire ropes 6 is retracted, thereby realizing the movement of the arc-shaped cleaning plate 2. The winch 5 can be controlled to rotate forward and backward by a control unit or limit switch, so as to realize the reciprocating motion of the arc-shaped cleaning plate 2, which scrapes along the inner wall of the hopper and pushes the adhered or accumulated material to the bottom outlet of the hopper body 1. The winch 5 can be set with cleaning frequency and stroke by the control unit, and the cleaning cycle can be adjusted according to the material characteristics. It can also be linked with the hopper level signal to realize on-demand cleaning.
[0027] like Figure 1 and Figure 3 As shown, the hopper body 1 is connected to an upper slide rail 3 and a middle slide rail 4 respectively. The upper and lower ends of the arc-shaped cleaning plate 2 are respectively provided with an upper guide groove 7 and a lower guide groove 8 that are adapted to the upper slide rail 3 and the middle slide rail 4. The arc-shaped cleaning plate 2 is connected to the upper slide rail 3 through the upper guide groove 7 and to the middle slide rail 4 through the lower guide groove 8 to achieve limiting and guiding. The slide rail and the guide groove can be plug-in type for easy connection, or they can be T-shaped or other structures to improve stability. In this embodiment, the upper slide rail 3 is fixedly installed on the upper edge of the top opening of the hopper body 1, and the middle slide rail 4 is fixed on the inner wall of the hopper body 1 (it is also possible to further modify the hopper body 1 by fixing the middle slide rail 4 to the inner ring of the lower flange of the hopper body 1, and the lower flange is connected to the feeding device), which facilitates the processing of the hopper body 1; the upper end of the arc-shaped cleaning plate 2 is connected to the upper connecting plate, and the upper connecting plate includes an abutment portion extending outward in the peripheral direction. The abutment portion abuts against the upper end of the hopper body 1. The abutment portion is arc-shaped or round, and the upper guide groove 7 is opened on the lower side of the abutment portion to improve the stability of the rotation of the abutment portion.
[0028] like Figure 1 and Figure 3As shown, the upper connecting plate at the upper end of the arc-shaped cleaning plate 2 is connected to the two sides of the upper connecting plate, and the outer ends of the pull rods 9 are connected to the corresponding traction wire ropes 6. The winch 5 is installed on the hopper body 1 and is connected to the pull rods 9 at both ends of the arc-shaped cleaning plate 2 through the traction wire ropes 6. The traction wire ropes 6 abut against the outer periphery of the upper slide rail 3 to transmit the traction force of the winch 5, thereby driving the arc-shaped cleaning plate 2 to rotate around the inner periphery of the hopper body 1.
[0029] The specific coordination during the operation of this device is as follows. When the material sticks to the wall of the hopper body 1 during the feeding process, the winch 5 is started according to the set cycle. The winch 5 pulls the cleaning plate 2 along the slide rail from one end to the other through the traction wire rope 6, completing one scraping stroke. Then the winch 5 reverses and pulls the cleaning plate back to the starting position to realize the reciprocating cleaning action. The scraped material falls along the hopper body 1 wall to the bottom outlet for discharge, effectively preventing material accumulation and blockage. The cleaning frequency and stroke can be flexibly set according to the actual material conditions.
[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Those skilled in the art can make various modifications or equivalent substitutions to the present utility model within its substance and protection scope, and such modifications or equivalent substitutions should also be considered to fall within the protection scope of the present utility model's technical solution.
