Description

Technical Field

[0001] The invention relates to the technical field of conveying equipment, in particular to a hanging conveyor for a fully mechanized mining face with raw gangue filling. Background Art

[0002] The main function of the original gangue filling is to digest and process the gangue produced by the mine, reduce the ground collapse rate, and improve the recovery rate of coal resources; the filling mining method refers to the mining method of filling the goaf with filling materials while accompanying the ore dropping, transportation and other operations. The purpose of filling is to support the rocks on both sides of the goaf and create a foothold for the continued stratified recovery above. It is suitable for deposits where the ore and surrounding rock are unstable and no large exposed surface is allowed; deposits where the surface needs to be protected; deposits of rare precious metals or high-grade; sulfide deposits with spontaneous combustion; deposits with complex occurrence conditions, etc.

[0003] Chinese patent CN213707083U discloses a multi-point unloading and conveying device for an aging warehouse, which includes a conveying mechanism and multiple unloading mechanisms, multiple unloading mechanisms are arranged at one end of the conveying mechanism away from the ground, multiple unloading mechanisms are located in the conveying direction of the conveying mechanism, and the unloading mechanism is located above the stacking point. This application connects multiple baffles by rotation on the conveying crossbeam, and the baffle is located above the unloading point. When the raw materials conveyed by the conveying device do not correspond to the stacking point below the baffle, the baffle is rotated to a position that does not affect the conveying of the raw materials. When the raw materials conveyed by the conveying device correspond to the stacking point below the baffle, the baffle is rotated to the conveying direction of the raw materials, and the baffle is used to guide the raw materials so that the raw materials fall from both sides of the conveying direction to the corresponding stacking point below.

[0004] When the unloading point of the conveying device is changed, it is necessary to manually move the baffle to adjust the unloading position. The conveyor belt used for raw gangue filling is wider and the weight of the baffle is correspondingly heavier. When the conveyor belt is set at an angle, it is more laborious to slide the baffle upward. Driving the movement of the baffle by motors, hydraulic equipment, etc. will increase the production cost of the conveying device.

[0005] Therefore, it is necessary to provide a hanging conveyor for fully mechanized mining working face with raw gangue filling to solve the above technical problems. Summary of the invention

[0006] The object of the present invention is to provide a hanging conveyor for fully mechanized mining working face with raw gangue filling, so as to solve the problems raised in the above-mentioned background technology.

[0007] In order to achieve the above-mentioned purpose, the present invention provides the following technical scheme: a hanging conveyor for a fully mechanized mining working face filled with raw gangue, comprising a top beam and a frame, the frame being connected to the bottom of the top beam, characterized in that: a conveyor belt is arranged on the frame, a baffle is arranged on the top of the conveyor belt, the baffle is slidably matched with the frame, a feeding plate is fixedly installed on the side wall of the baffle, when the material moves to contact with the feeding plate, as the conveyor belt moves, the material slides down from both sides of the conveyor belt along the side wall of the feeding plate; a plurality of grooves are provided on the conveyor belt, and anti-slip bars are slidably installed in the plurality of grooves, the anti-slip bars are elastically connected to the bottom inner wall of the groove, the top wall of the anti-slip bar is arranged in an inclined shape, when the conveyor belt transports the material, as the anti-slip bar moves to contact with the feeding plate, the feeding plate pushes the anti-slip bar toward the inside of the groove through the inclined surface of the anti-slip bar, and when the conveyor belt rotates in the opposite direction, as the anti-slip bar moves to contact with the baffle, the side of the anti-slip bar pushes the baffle to move on the frame.

[0008] As a further solution of the present invention, two opposite sides of the baffle extend from above the conveyor belt, and inclined plates are fixedly installed at the bottom ends of the two opposite sides; when the material slides along the guide part of the unloading plate to the two sides of the conveyor belt, it first falls on the inclined plates, thereby cushioning the fall of the material.

[0009] As a further solution of the present invention, two opposite side walls of the frame are provided with slide grooves, two slide grooves are slidably mounted with slide seats, and two slide seats are fixedly connected to the baffle.

[0010] As a further solution of the present invention, a first spring is arranged in the groove, and the anti-slip rod is elastically connected to the bottom inner wall of the groove through the first spring.

[0011] As a further solution of the present invention, a limit block is fixedly installed on the side wall of the slide seat, and the limit block is slidably arranged in the slide groove. The inner wall of the slide groove is provided with a plurality of limit grooves, and the plurality of limit grooves are located on the same straight line. A limit column is slidably installed on the limit block, and the limit column is adapted to the limit groove. When the limit column is inserted into the limit groove, the limit block is locked so that it cannot slide in the slide groove.

[0012] As a further solution of the present invention, a cavity is opened in the sliding seat, a second spring is arranged in the cavity, one end of the limit column extends into the cavity, and the end is fixedly connected to one end of the second spring, and the end of the limit column located in the cavity is fixedly connected to a traction rope; when the traction rope is pulled, one end of the traction rope pulls the limit column out of the limit groove, and then the sliding seat can be slid to adjust the position of the baffle.

[0013] As a further solution of the present invention, an adjusting column is slidably installed at the bottom of the side wall of the baffle away from the blanking plate, and an installation cavity is opened inside the baffle, and a slider is slidably installed in the installation cavity, one end of the adjusting column is fixedly connected to the slider, one end of the traction rope extends into the installation cavity and is fixedly connected to the side wall of the slider close to the adjusting column; when the slider moves toward the inside of the installation cavity, the slider pulls the traction rope to move into the inside of the installation cavity, and the adjusting column and the anti-slip bar are arranged at the same height, so that when the conveyor belt rotates in the opposite direction, the side wall of the anti-slip bar can push the adjusting column to move toward the inside of the installation cavity.

[0014] As a further solution of the present invention, the bottom wall of the adjusting column is provided with an anti-slip layer, and the anti-slip layer is made of anti-slip material, or an anti-slip groove is provided on the bottom wall of the adjusting column. The provision of the anti-slip layer makes it possible for the top wall of the anti-slip rod to contact the bottom wall of the adjusting column when the sliding block is obstructed and difficult to slide. As the anti-slip rod moves, the anti-slip rod can pull the adjusting column out of the installation cavity, thereby preventing the elastic force of the second spring from being difficult to pull the sliding block to move.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the frame of the present invention is suspended in the air by the top beam, and there is no need to set the supporting structure at the bottom of the goaf, which is convenient for filling the goaf, and the material can be transported by the conveyor belt. When the material moves to contact with the unloading plate, as the conveyor belt moves, the material slides down from both sides of the conveyor belt along the side walls of the unloading plate. When the unloading position needs to be adjusted upward, the conveyor belt is controlled to rotate in the opposite direction. When the conveyor belt rotates in the opposite direction, as the anti-slip rod moves to contact with the baffle, the side of the anti-slip rod pushes the baffle to tilt upward on the frame. The conveyor belt is used to move upward, and the baffle plate slides, which drives the unloading plate to slide. The material is transported to the position of the unloading plate and can be unloaded, thereby realizing the position of the unloading plate being adjusted by the power of the conveyor belt. When the unloading position needs to be adjusted downward, the unloading plate and the baffle plate can be manually slid due to the small resistance, thereby realizing multi-point unloading. The present invention drives the movement of the baffle plate and the unloading plate through the power of the conveyor belt, making the adjustment of the unloading point more convenient and eliminating the need for driving equipment, thereby reducing the production cost of the conveyor, thereby evenly filling the goaf, and facilitating use when filling the goaf.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figures 1 to 5In an embodiment of the present invention, a hanging conveyor for a fully mechanized mining face filled with raw gangue includes a top beam 3 and a frame 1. The frame 1 is connected to the bottom of the top beam 3. The frame 1 is suspended in the air through the top beam 3. Specifically, the frame 1 is connected to the top beam 3 through a plurality of hydraulic telescopic supports 4. The bottom ends of the hydraulic telescopic supports 4 are hinged to the frame 1. The hydraulic telescopic supports 4 are driven by hydraulic pressure, so that the frame 1 can be raised and lowered, so that the equipment can be moved upward as the filling height increases. A conveyor belt 2 is provided on the frame 1. A motor 17 is fixedly installed on the side wall of the frame 1. A transmission roller (not shown in the figure) is provided in the frame 1. The conveyor belt 2 is sleeved on a plurality of transmission rollers. The motor 17 is connected to the transmission roller in transmission. The plurality of transmission rollers are driven to rotate by the motor 17. When the transmission roller rotates, the conveyor belt 2 is driven to rotate, thereby transporting the materials on the conveyor belt 2. A baffle is provided at the top of the conveyor belt 2. The material is transported to the position of the feed plate 6, and the material is discharged from the feed plate 6 by the feed conveyor 2, thereby realizing multi-point discharge, thereby achieving uniform filling of the goaf, and convenient for use in filling the goaf.

[0030] In this embodiment, preferably, the two opposite sides of the baffle plate 5 extend from above the conveyor belt 2, and the bottom ends of the two opposite sides are fixedly installed with inclined plates 7; when the material slides along the guide portion of the unloading plate 6 to the two sides of the conveyor belt 2, it first falls on the inclined plates 7, thereby cushioning the fall of the material and reducing the dust generated when the material falls.

[0031] In this embodiment, preferably, two opposite side walls of the frame 1 are provided with a slide groove 9, and a slide seat 10 is slidably installed on the two slide grooves 9, and the two slide seats 10 are fixedly connected to the baffle 5, so as to realize the sliding installation of the baffle 5 on the frame 1.

[0032] See also Fig.10In the embodiment of the present invention, a plurality of grooves are provided on the conveyor belt 2, and an anti-slip bar 8 is slidably installed in the groove. A first spring 16 is provided in the groove, and the anti-slip bar 8 is elastically connected to the bottom inner wall of the groove through the first spring 16, that is, the top end of the first spring 16 is fixedly connected to the bottom wall of the anti-slip bar 8, and the bottom end of the first spring 16 is fixedly connected to the bottom inner wall of the groove. The top wall of the anti-slip bar 8 is arranged in an inclined shape. When the anti-slip bar 8 moves to contact the unloading plate 6, as the anti-slip bar 8 continues to move, the unloading plate 6 pushes the anti-slip bar 8 toward the inside of the groove through the inclined surface of the top wall of the anti-slip bar 8; when the conveyor belt 2 is arranged at an angle, the material on the conveyor belt 2 may slide, so the anti-slip bar 8 is arranged. Since the anti-slip bar 8 is telescopically arranged in the groove, the anti-slip bar 8 will not hinder the conveyor belt 2 from passing under the baffle 5.

[0033] See also Figures 6 to 9 In the embodiment of the present invention, a limit block 1001 is fixedly installed on the side wall of the slide seat 10, and the limit block 1001 is slidably set in the slide groove 9. The inner wall of the slide groove 9 is provided with a plurality of limit grooves 901, and the plurality of limit grooves 901 are located on the same straight line. A limit column 11 is slidably installed on the limit block 1001, and the limit column 11 is adapted to the limit groove 901. When the limit column 11 is inserted into the limit groove 901, the limit block 1001 is locked so that it cannot slide in the slide groove 9.

[0034] In this embodiment, preferably, a cavity is opened in the slide seat 10, a second spring 15 is arranged in the cavity, one end of the limit column 11 extends into the cavity, and the end is fixedly connected to one end of the second spring 15, and the end of the limit column 11 located in the cavity is fixedly connected to a traction rope 14; when the traction rope 14 is pulled, one end of the traction rope 14 pulls the limit column 11 out of the limit groove 901, and then the slide seat 10 can be slid to adjust the position of the baffle 5.

[0035] In this embodiment, preferably, an adjusting column 12 is slidably installed at the bottom of the side wall of the baffle 5 away from the blanking plate 6, an installation cavity 501 is opened inside the baffle 5, a slider 13 is slidably installed in the installation cavity 501, one end of the adjusting column 12 is fixedly connected to the slider 13, one end of the traction rope 14 extends into the installation cavity 501 and is fixedly connected to the side wall of the slider 13 close to the adjusting column 12, when the slider 13 moves toward the inside of the installation cavity 501, the slider 13 pulls the traction rope 14 to move to the installation cavity 501 Internally, the adjusting column 12 and the anti-slip rod 8 are arranged at the same height, so that when the conveyor belt 2 rotates in the opposite direction, the side wall of the anti-slip rod 8 can push the adjusting column 12 to move toward the inside of the installation cavity 501; the anti-slip rod 8 can not only play an anti-slip role, but also drive the adjusting column 12 to move to unlock the slide seat 10, thereby reducing the preparation cost of the equipment; when filling the goaf, materials are usually transported from a higher position to a lower position, and the conveyor belt 2 is inclined. When it is inclined, it is more difficult for the blanking plate 6 to slide upward at an angle, so the above-mentioned structure is set.

[0036] In order to change the unloading position, it is necessary to adjust the positions of the baffle 5 and the unloading plate 6. Due to the large weight of the baffle 5 and the unloading plate 6, it is difficult to push the slide seat 10 when the conveyor belt 2 is tilted. Therefore, the above-mentioned structure is set. When it is necessary to push the baffle 5 to move to the left, the conveyor belt 2 is controlled to rotate in the opposite direction. When the conveyor belt 2 rotates in the opposite direction, the anti-slip bar 8 is driven to move in the opposite direction. After the anti-slip bar 8 moves to contact the adjusting column 12, the side wall of the anti-slip bar 8 pushes the adjusting column 12 to move toward the inside of the installation cavity 501, so that the slider 13 pulls the traction rope 14 to move to the inside of the installation cavity 501. When the traction rope 14 moves, one end of the traction rope 14 pulls the limit column 11 out of the limit groove 901, thereby releasing the lock of the slide seat 10. As the anti-slip bar 8 continues to move, the anti-slip bar 8 pushes the baffle 5 to move to the left, thereby adjusting the positions of the baffle 5 and the unloading plate 6, making the adjustment of the baffle 5 more convenient and easy to use.

[0037] In this embodiment, preferably, refer to Fig.11 The bottom wall of the adjusting column 12 is provided with an anti-slip layer 1201, and the anti-slip layer 1201 is made of anti-slip material, or an anti-slip groove is provided on the bottom wall of the adjusting column 12. The setting of the anti-slip layer 1201 makes it difficult for the slider 13 to slide when it is blocked. After the top wall of the anti-slip rod 8 contacts the bottom wall of the adjusting column 12, as the anti-slip rod 8 moves, the anti-slip rod 8 can pull the adjusting column 12 out of the mounting cavity 501, thereby preventing the elastic force of the second spring 15 from being difficult to pull the slider 13 to move.

[0038] Working principle: the frame 1 of the present invention is suspended in the air by the top beam 3, and there is no need to set the supporting structure at the bottom of the goaf, which is convenient for filling the goaf. The material can be transported by the conveyor belt 2. When the material moves to contact the discharge plate 6, as the conveyor belt 2 moves, the material slides along the guide part of the discharge plate 6 to the two sides of the conveyor belt 2 and falls on the inclined plate 7, thereby buffering the fall of the material, thereby reducing the dust generated when the material falls. When it is necessary to adjust the discharge position, the sliding baffle 5 is used. When the baffle 5 slides, it drives the discharge plate 6 to slide. The material can be discharged when it is transported to the discharge plate 6 position, thereby realizing multi-point discharge, thereby filling the goaf. The conveyor belt 2 is controlled to rotate in the opposite direction, and the anti-slip bar 8 is driven to move in the opposite direction when the conveyor belt 2 rotates in the opposite direction. After the anti-slip bar 8 moves to contact with the adjusting column 12, the side wall of the anti-slip bar 8 pushes the adjusting column 12 to move toward the inside of the installation cavity 501, so that the slider 13 pulls the traction rope 14 to move to the inside of the installation cavity 501. When the traction rope 14 moves, one end of the traction rope 14 pulls the limiting column 11 out of the limiting groove 901, thereby releasing the lock on the slide seat 10. As the anti-slip bar 8 continues to move, the anti-slip bar 8 pushes the baffle 5 to move to the left, thereby adjusting the positions of the baffle 5 and the blanking plate 6.

[0039] The above description is a detailed description of the preferred feasible embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modified changes completed under the technical spirit suggested by the present invention should fall within the patent scope covered by the present invention.
