Description

A mining conveyor belt anti-jamming and slag removal mechanism Technical Field

[0001] This utility model relates to the field of mining equipment technology, specifically to a mining conveyor belt anti-jamming and slag-removing mechanism. Background Technology

[0002] In mining operations, conveyor belts are the core equipment for material transportation. Their surfaces are often jammed due to the adhesion of slag and clumps of material. Traditional slag removal mechanisms mostly use fixed scraper structures, which remove material through the contact between the toothed scraper and the surface of the conveyor belt.

[0003] However, such structures have significant limitations in practical applications: conventional slag discharge guide plates are mostly fixed installations and can only discharge slag in a single direction (such as one side of a belt conveyor). When the working environment or process requirements change and the slag discharge direction needs to be adjusted, the entire slag cleaning mechanism often needs to be symmetrically disassembled or its position changed. In complex mining conditions, such mechanical adjustments are not only time-consuming and labor-intensive, but also have problems such as component wear and reduced positioning accuracy due to frequent disassembly and assembly, which seriously restricts slag cleaning efficiency.

[0004] Furthermore, the fixed slag discharge design is difficult to adapt to the slag cleaning needs of different sections of the conveyor belt. Especially in narrow conveyor systems or scenarios requiring multi-point slag discharge, the problem of insufficient slag discharge flexibility of traditional structures is more prominent. Therefore, it is urgent to develop a slag cleaning mechanism with rapid directional adjustment capability and no need for overall disassembly to meet the dynamic slag cleaning needs of mine conveyor systems. Summary of the Invention

[0005] The purpose of this utility model is to provide a material jamming and slag removal mechanism for mine conveyor belts, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mine conveyor belt anti-jamming and slag-removing mechanism, comprising:

[0007] The frame has a concave structure with the recessed part facing the surface of the conveyor belt;

[0008] The first and second sawtooth scrapers are sequentially arranged inside the frame along the conveying direction, with their sawtooths interspersed and their length greater than the width of the conveyor belt.

[0009] The slag discharge guide plate has a horizontal section that fits against the surface of the conveyor belt, and an inclined section that is rotatably connected to the inside of the frame.

[0010] A fixed base is fixed to the inner wall of the frame and hinged to one end of the slag discharge guide plate;

[0011] Guide rails are symmetrically arranged within the operating windows on both sides of the frame;

[0012] The guide frame is slidably disposed between the guide rails and is movably connected to the other end of the slag discharge guide plate;

[0013] The movable seat is slidably embedded in the groove of the guide rail and fixed to the guide frame by fastening bolts.

[0014] Using the above technical solution, the concave frame wraps around the surface of the conveyor belt, and the two serrated scrapers are arranged in an alternating pattern to form a double scraping mechanism, which effectively removes adhesive materials of different shapes. The slag discharge guide plate achieves adjustable tilt angle and slag discharge direction through the linkage design of fixed seat and movable guide frame. The guide rail system allows the operator to switch the slag discharge direction on both sides of the conveyor belt through the sliding adjustment mechanism without disassembling any parts.

[0015] As a preferred technical solution of this utility model, the operation window is symmetrically opened at both ends of the frame, and the axis of the slide groove of the internal guide rail is perpendicular to the conveying direction.

[0016] The above technical solution, with its symmetrical layout on both sides of the operating window and the chute axis perpendicular to the conveying direction, forms a bidirectional adjustment channel. This design enables the slag discharge guide plate to have bidirectional adjustment capability, allowing operators to choose to discharge slag to the left or right according to the on-site working conditions. It is particularly suitable for operation scenarios that require alternating cleaning of material accumulation on both sides of the conveyor belt.

[0017] As a preferred technical solution of this utility model, the first serrated scraper and the second serrated scraper are respectively fixed to the inner wall of the frame by mounting bases, and reinforcing ribs are provided between the mounting bases and the frame.

[0018] Using the above technical solution, the spatial layout of the three-stage slag removal system forms a progressive processing flow. The first scraper is responsible for removing large clumps of material, the second scraper cleans up residual fine slag, and finally the material is concentrated and guided by the adjustable slag discharge plate. This distribution method effectively avoids secondary accumulation of material on the conveyor belt surface.

[0019] As a preferred technical solution of this utility model, the mounting base and the sawtooth scraper are detachably connected through a pin hole through a fixing pin.

[0020] By adopting the above technical solution, the modular mounting base and the reinforcing ribs form a triangular support structure to ensure the stability of the serrated scraper during continuous scraping operations. This design not only ensures the effective contact pressure between the scraper and the conveyor belt, but also disperses the impact load of the material and prevents stress fracture at the root of the scraper.

[0021] As a preferred technical solution of this utility model, the guide frame has a U-shaped structure, with its open end slidingly engaged with the edge of the slag discharge guide plate, and its closed end connected to the guide rail through the movable seat.

[0022] By adopting the above technical solution, the pin-type connection structure enables the quick replacement of scrapers. When the scraper teeth are worn, maintenance personnel only need to pull out the fixing pin to replace the new scraper, avoiding the thread seizing problem caused by the traditional bolt connection method and significantly shortening the downtime for maintenance.

[0023] As a preferred technical solution of this utility model, the fastening bolt passes through the movable seat and abuts against the side wall of the slide groove, and is fixed by friction by tightening the thread.

[0024] Using the above technical solution, the sliding fit structure of the U-shaped guide frame forms a self-guiding adjustment system. When adjusting the slag discharge direction, the guide frame slides freely along the edge of the slag discharge plate. At the same time, the rigid connection between the closed end and the guide rail maintains the straightness of the adjustment trajectory, ensuring that the slag discharge plate angle adjustment is precise and controllable.

[0025] As a preferred technical solution of this utility model, the fastening bolt passes through the movable seat and abuts against the side wall of the slide groove, and is fixed by friction by tightening the thread.

[0026] Using the above technical solution, the friction locking mechanism achieves positioning through the extrusion friction between the bolt end face and the side wall of the slide. This design abandons the traditional threaded hole positioning method, allows for instant locking at any adjustment position, and will not cause thread wear failure due to frequent adjustment.

[0027] As a preferred technical solution of this utility model, the first toothed scraper is installed close to the feed end of the conveyor belt, and the first toothed scraper, the second toothed scraper and the slag discharge guide plate are distributed in sequence in the belt conveying direction.

[0028] As a preferred technical solution of this utility model, the inner wall of the guide rail is provided with a T-shaped guide groove that matches the shape of the movable seat, and the length of the guide groove covers the entire adjustment stroke of the operation window.

[0029] The above technical solution uses an interlocking design between the T-shaped guide groove and the movable seat to form an anti-derailment protection mechanism. The design of the guide groove covering the entire length of the adjustment stroke ensures that the slag discharge plate can smoothly transition from the maximum left deviation position to the maximum right deviation position, preventing the risk of jamming or detachment from the guide rail during the adjustment process.

[0030] Compared with existing technologies, the beneficial effects of this utility model's anti-jamming and slag-removing mechanism for mining conveyor belts are:

[0031] Through the cooperation of the guide rail linkage mechanism and the rotatable slag discharge guide plate, the tilt angle and slag discharge direction of the slag discharge plate can be infinitely adjusted, and the switching between left and right bidirectional slag discharge modes can be completed quickly. This effectively adapts to the material cleaning needs of different sections of the conveying system. The design of the double sawtooth scraper staggered layout is adopted. After the front scraper breaks up large pieces of material, the rear scraper cleans the remaining fine slag a second time, forming a stepped slag cleaning path, which significantly improves the stripping efficiency of residual materials on the surface of the conveyor belt.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Please refer to Figures 1-5. This utility model provides a technical solution: a mine conveyor belt anti-jamming and slag-removing mechanism, comprising:

[0040] The frame 1 has a concave structure with the recessed part facing the surface of the conveyor belt;

[0041] The first toothed scraper 3 and the second toothed scraper 4 are arranged sequentially inside the frame 1 along the conveying direction, with their teeth staggered and their length greater than the width of the conveyor belt.

[0042] The slag discharge guide plate 6 has a horizontal section that fits against the surface of the conveyor belt, and an inclined section that is rotatably connected to the inside of the frame 1.

[0043] The fixed base 5 is fixed to the inner wall of the frame 1 and hinged to one end of the slag discharge guide plate 6;

[0044] Guide rails 7 are symmetrically arranged in the operation windows 2 on both sides of the frame 1;

[0045] The guide frame 8 is slidably disposed between the guide rails 7 and is movably connected to the other end of the slag discharge guide plate 6;

[0046] The movable seat 9 is slidably embedded in the groove 13 of the guide rail 7 and fixed to the guide frame 8 by fastening bolts 14.

[0047] The frame 1 is pre-installed at the top of the conveyor belt. The frame 1 has a concave structure, with its concave part facing the belt. Inside the frame 1 are a first toothed scraper 3, a second toothed scraper 4, and a slag discharge guide plate 6, which are distributed sequentially in the belt conveying direction. The first toothed scraper 3 and the second toothed scraper 4 are the same size, but the teeth of the first toothed scraper 3 and the second toothed scraper 4 are staggered and do not overlap. This arrangement ensures that after the first toothed scraper 3 breaks up the arch, the unbroken portion is left for the second toothed scraper. 4. To break up the arch and reduce dead angles, the length of the first sawtooth scraper 3 and the second sawtooth scraper 4 should be much greater than the width of the belt. The first sawtooth scraper 3 and the second sawtooth scraper 4 are positioned to correspond to the mounting base 10 of the frame 1. The mounting base 10 and the two sawtooth scrapers are respectively provided with corresponding pin holes. After the pin holes are aligned, they can be fastened with fixing pins 12. Disassembly only requires removing the fixing pins 12 and taking out the first sawtooth scraper 3 or the second sawtooth scraper 4. Ribs 11 are also provided between the mounting base 10 and the frame 1 for reinforcement connection.

[0048] The bottom of the slag discharge guide plate 6 is horizontal, and its bottom is in contact with the surface of the conveyor belt. The slag discharge guide plate 6 is a movable structure. It uses its tilt angle to guide and discharge the slag. The slag discharge principle is as follows: the conveyor belt transports the loosened slag forward, which is then blocked by the slag discharge guide plate 6. Because the slag discharge guide plate 6 is tilted, the slag slides along its surface until it falls off at the junction of one end of the guide plate 6 and the conveyor belt. The slag discharge guide plate 6 is rotatable, and its rotation is used to adjust the direction of the slag discharge opening. If one end of the guide plate 6 rotates forward, the slag discharge area is at the left end; if the other end rotates backward, the slag discharge area is at the rear end. The specific adjustment principle is as follows: the slag discharge guide plate 6 is centered on the fixed base 5, which is located on the inner wall of the frame 1. The other end of the guide plate 6 passes through the guide... Inside the frame 8, the guide frame 8 is positioned between the upper and lower guide rails 7, which are located inside the operation window 2. The operation window 2 is pre-set at one end of the frame 1, symmetrical to the position of the fixed seat 5. A movable seat 9 is also provided between the guide frame 8 and the guide rail 7 for rotational adjustment. A sliding groove 13 is also provided inside the top guide rail 7. When the rotation angle of the slag discharge guide plate 6 changes, the slag discharge guide plate 6 slides inside the guide frame 8, and the guide frame 8 rotates around the movable seat 9 as the center end. After adjustment, the guide frame 8 and the upper movable seat 9 are fixed by fastening bolts 14. The fixing principle is that the movable seat 9 is threadedly connected to the fastening bolt 14. Through the connection, one end of the fastening bolt 14 is continuously pushed into the sliding groove 13 until one end of the fastening bolt 14 is pressed against the outer wall of the sliding groove 13 to increase the friction and achieve the fixing effect.
