Technical Field

[0001] This utility model relates to the technical field of conveyor belt feeding hoppers, specifically a wear-resistant and anti-sticking device for conveyor belt feeding hoppers. Background Technology

[0002] In existing technologies, the sintered mixtures conveyed in the mixing line have characteristics such as large quantity, high moisture content, high alkalinity, and high viscosity, which easily cause adhesion and blockage of the feed hopper of the belt conveyor in the mixing line. The finished sintered ore conveyed in the finished product line has characteristics such as large particle size, high hardness, high density, and high temperature, which easily cause erosion and wear on the feed hopper of the belt conveyor, resulting in hopper wear-through, liner detachment, and secondary accidents such as scratches on the downstream conveyor belt. These problems restrict the production line operating rate and result in a high failure rate and maintenance workload. Therefore, it is necessary to propose a wear-resistant and anti-sticking device for the feed hopper of the belt conveyor to solve the above-mentioned problems. Utility Model Content

[0003] The purpose of this utility model is to provide a wear-resistant and anti-sticking device for the feeding hopper of a belt conveyor, which can effectively solve the problems of material sticking, wear, and hopper component detachment in the hopper when conveying high-volume, high-hardness, or high-viscosity materials on various belt conveyors. Especially in the production operation of mining belt conveyors, it can effectively reduce the downtime maintenance time caused by material sticking, blockage, wear, or component detachment in the feeding hopper, while reducing the amount of maintenance work on the feeding hopper of the belt conveyor, and facilitating the maintenance and replacement of the wear-resistant liner.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant and anti-sticking device for a conveyor belt feeding hopper, comprising a hopper body, wherein a hanging groove is provided through the outer wall of the hopper body, a hanging steel pipe is provided inside the hanging groove, a wear-resistant liner plate located inside the hopper body is fixedly connected to the lower side of the outer wall of the hanging steel pipe, a connecting block is fixedly connected to the left side of the wear-resistant liner plate, a contact ball is fixedly connected to the other end of the connecting block, a frame is installed on the left side of the inner wall of the hopper body, a sliding plate located to the left of the contact ball is provided inside the frame, a connecting rod passing through a round hole through the hopper body is fixedly connected to the left side of the sliding plate, a connecting plate is fixedly connected to the left end of the connecting rod, and a tension spring sleeved on the outer wall of the connecting rod is fixedly connected between the connecting plate and the left end face of the hopper body.

[0005] In order to restrict the movement of the hanging steel pipe, as a preferred embodiment of the wear-resistant and anti-sticking material device for the conveyor belt feeding hopper of this utility model, the inside of the hanging groove is provided with a limiting block located on the upper side of the outer wall of the hanging steel pipe, the upper end of the limiting block is fixedly connected to a connecting seat, and the outer wall of the hopper body is fixedly connected to a connecting plate located on the left side of the hanging groove. The connecting plate and the connecting seat are fixedly connected by multiple bolts.

[0006] To improve the stability of skateboarding, in a preferred embodiment of the wear-resistant and anti-sticking material device for the conveyor belt feed hopper of this utility model, the skateboard is slidably connected to the upper and lower sides of the inner wall of the frame via slide rails.

[0007] In order to prevent the liner from falling, as a preferred embodiment of the wear-resistant and anti-sticking material device for the conveyor belt feeding hopper of this utility model, a through hole is provided on the left side of the outer wall of the hopper body located above the frame, and a steel wire rope passing through the through hole is fixedly connected between the left side of the wear-resistant liner and the left side of the outer wall of the hopper body.

[0008] In order to facilitate the conveyor belt to deliver materials into the interior of the hopper body, as a preferred embodiment of the wear-resistant and anti-sticking material device for the conveyor belt feeding hopper of this utility model, an inlet is provided through the right side of the outer wall of the hopper body.

[0009] To improve the stability of the connection between the hanging steel pipe and the wear-resistant liner, the preferred embodiment of the wear-resistant and anti-sticking material device for the conveyor belt discharge hopper of this utility model is that the hanging steel pipe and the wear-resistant liner are fully welded on both sides.

[0010] To facilitate friction between the smaller contact ball and the sliding plate, the contact ball, preferably a smooth spherical surface, is used in the wear-resistant and anti-sticking material device for the conveyor belt feed hopper of this invention.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] By directly absorbing the scouring of materials through wear-resistant liners, the wear of the hopper and the detachment of hopper components can be effectively solved when various belt conveyors are conveying high-volume, high-hardness, or high-viscosity materials.

[0013] Meanwhile, when the wear-resistant liner receives the flushing of materials, the extension or contraction of the tension spring will cause the wear-resistant liner to swing left and right with the hanging steel pipe, which effectively solves the problem of material sticking and clogging.

[0014] Wear-resistant liners have good wear resistance, which on the one hand extends the service life in the liners. On the other hand, when the service life expires, the worn-resistant liners and the hanging steel pipes can be removed and replaced, which further reduces the maintenance workload of the conveyor feed hopper and facilitates the maintenance and replacement of the wear-resistant liners.

[0019] Please see Figures 1 to 3 A wear-resistant and anti-sticking device for a conveyor belt feed hopper includes a hopper body 1. The outer wall of the hopper body 1 has a through-hole 2 for hanging. A hanging steel pipe 15 is installed inside the hanging groove 2. A wear-resistant liner 3 located inside the hopper body 1 is fixedly connected to the lower side of the outer wall of the hanging steel pipe 15. A connecting block 4 is fixedly connected to the left side of the wear-resistant liner 3. A contact ball 5 is fixedly connected to the other end of the connecting block 4. A frame 6 is installed on the left side of the inner wall of the hopper body 1. A sliding plate 16 located to the left of the contact ball 5 is installed inside the frame 6. A connecting rod 7 passing through a round hole and penetrating the hopper body 1 is fixedly connected to the left side of the sliding plate 16. A connecting plate 8 is fixedly connected to the left end of the connecting rod 7. A tension spring 9 sleeved on the outer wall of the connecting rod 7 is fixedly connected between the connecting plate 8 and the left end face of the hopper body 1.

[0020] In this embodiment: the material is delivered to the inside of the funnel body 1 by a belt conveyor. At this time, the wear-resistant liner 3 is blocked in front of the left side of the inner wall of the funnel body 1. The material can be directly scouted by the wear-resistant liner 3, which can effectively solve the problem of wear and detachment of funnel parts when various belt conveyors are conveying high-volume, high-hardness or high-viscosity materials.

[0021] Meanwhile, when the wear-resistant liner 3 receives the flushing of materials, the flushing force causes the wear-resistant liner 3 to swing to the left along with the hanging steel pipe 15. At the same time, the connecting block 4 and the contact ball 5 cause the slide plate 16 to slide to the right, and the connecting rod 7 and the connecting plate 8 stretch the tension spring 9 to the left. Since the flushing force of the material changes constantly, the contraction force of the tension spring 9 causes the slide plate 16 to move to the right, and the wear-resistant liner 3 swings to the right along with the hanging steel pipe 15. Thus, the reciprocating swing of the wear-resistant liner 3 effectively solves the problem of material sticking and clogging.

[0022] The wear-resistant liner 3 has good wear resistance, which on the one hand extends the online service life to a certain extent, and on the other hand, when the service life expires, the hanging wear-resistant liner 3 and the hanging steel pipe 15 can be easily removed and replaced, which is very convenient to use. This further reduces the maintenance workload of the belt conveyor discharge hopper and facilitates the maintenance and replacement of the wear-resistant liner.

[0023] As a technical optimization of this utility model, the inside of the hanging groove 2 is provided with a limiting block 10 located on the upper side of the outer wall of the hanging steel pipe 15. The upper end of the limiting block 10 is fixedly connected to a connecting seat 11. The outer wall of the funnel body 1 is fixedly connected to a connecting plate 12 located on the left side of the hanging groove 2. The connecting plate 12 and the connecting seat 11 are fixedly connected by multiple bolts.

[0024] In this embodiment: the moving position of the hanging steel pipe 15 can be restricted by the limiting block 10, and the position of the limiting block 10 can be fixed by fixing the connecting plate 12 and the connecting seat 11 with multiple bolts.

[0025] As a technical optimization of this utility model, the slide plate 16 is slidably connected to the upper and lower sides of the inner wall of the frame 6 via slide rails.

[0026] In this embodiment, two slide rails are provided to improve the stability of the skateboard 16 movement.

[0027] As a technical optimization of this utility model, a through hole 13 located above the frame 6 is provided on the left side of the outer wall of the funnel body 1, and a steel wire rope 14 passing through the through hole 13 is fixedly connected between the left side of the wear-resistant liner 3 and the left side of the outer wall of the funnel body 1.

[0028] In this embodiment, by passing the wire rope 14 through the through hole 13 and fixing it to the left side of the wear-resistant liner 3 and the left side of the outer wall of the funnel body 1, the liner can be prevented from falling.

[0029] As a technical optimization of this utility model, an inlet 17 is provided through the right side of the outer wall of the funnel body 1.

[0030] In this embodiment: by setting inlet 17, the belt conveyor can deliver the material into the interior of the funnel body 1.

[0031] As a technical optimization of this utility model, the hanging steel pipe 15 and the wear-resistant liner 3 are fully welded on both sides.

[0032] In this embodiment, by making the hanging steel pipe 15 and the wear-resistant liner 3 fully welded on both sides, the stability of the connection between the hanging steel pipe 15 and the wear-resistant liner 3 can be improved.

[0033] As a technical optimization of this utility model, the contact ball 5 has a smooth spherical surface.

[0034] In this embodiment, the contact ball 5 is set to a smooth spherical surface to reduce the friction between the contact ball 5 and the slide plate 16.

[0035] Working principle: First, the material is sent to the inside of the funnel body 1 by the belt conveyor. At this time, the wear-resistant liner 3 is blocked in front of the left side of the inner wall of the funnel body 1. The material can be directly scoured by the wear-resistant liner 3, which can effectively solve the problem of wear and detachment of funnel parts when various belt conveyors are conveying high-volume, high-hardness or high-viscosity materials.

[0036] Meanwhile, when the wear-resistant liner 3 receives the flushing of materials, the flushing force causes the wear-resistant liner 3 to swing to the left along with the hanging steel pipe 15. At the same time, the connecting block 4 and the contact ball 5 cause the slide plate 16 to slide to the right, and the connecting rod 7 and the connecting plate 8 stretch the tension spring 9 to the left. Since the flushing force of the material changes constantly, the contraction force of the tension spring 9 causes the slide plate 16 to move to the right, and the wear-resistant liner 3 swings to the right along with the hanging steel pipe 15. Thus, the reciprocating swing of the wear-resistant liner 3 effectively solves the problem of material sticking and clogging.

[0037] Meanwhile, due to the good wear resistance of the wear-resistant liner 3, on the one hand, it can extend the online service life to a certain extent. On the other hand, when the service life expires, multiple bolts can be unscrewed, and the limiting block 10 and connecting seat 11 can be removed, which makes it easy to take out the hanging wear-resistant liner 3 and the hanging steel pipe 15 for replacement. It is very convenient to use, further reducing the maintenance workload of the belt conveyor discharge hopper, and making it convenient to maintain and replace the wear-resistant liner.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
