Description

Technical Field

[0001] The utility model relates to the technical field of transfer machine equipment, in particular to a coal discharging device for the head of a transfer machine. Background Art

[0002] At present, the coal outlet at the head of the fully-mechanized mining transfer machine used in our mine is empty below. Coal blocks and gangue directly fall on the lower belt from the sprocket, with a drop of about 1.5 meters. Moreover, the transfer machine has the same width as the lower belt (1.2 meters). This directly leads to serious spilling of coal blocks and gangue, excessive stress on the belt, shortening the normal service life of the belt. In addition, the coal baffle needs to be replaced frequently, and the belt rack is also damaged and deformed to varying degrees. At the same time, the high drop and the hollow air duct cause an increase in dust at the tail of the belt conveyor and the transfer bridge, seriously affecting the working environment of the fully-mechanized mining face and posing a great hazard to safe production. Content of the Utility Model

[0003] The purpose of the utility model is to provide a coal discharging device for the head of a transfer machine, so as to solve the problems caused by the excessive drop between the transfer machine and the belt conveyor, such as serious spilling of coal blocks and gangue, excessive stress on the belt, shortening the normal service life of the belt, frequent replacement of the coal baffle, varying degrees of damage and deformation of the belt rack, and at the same time, the high drop and the hollow air duct cause an increase in dust at the tail of the belt conveyor and the transfer bridge, seriously affecting the working environment of the fully-mechanized mining face.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A coal discharging device for the head of a transfer machine, including a transfer machine, a belt conveyor, and a coal discharging device arranged between the discharging port of the transfer machine and the belt conveyor. The coal discharging device includes a bottom plate, a support plate, a first transport plate, a second transport plate, a coal baffle, and a buffer plate. The left and right sides of the bottom plate are symmetrically connected to the small-sliding protection plates between the discharging port of the transfer machine and the belt conveyor respectively. The rear side of the bottom end of the bottom plate is connected with a support plate, and the support plate is set up in a right-angled triangle. The inclined ends of the two support plates are connected with a first transport plate, which is arranged at the discharging port of the transfer machine. The top end of the first transport plate is connected with a second transport plate arranged at an angle. The left and right sides of the second transport plate are respectively connected with obliquely arranged coal baffles, and the bottom ends of the coal baffles are connected with the bottom plate. A buffer plate is hinged between the two coal baffles on both sides. The buffer plate is set in a conical shape, and the conical end fits the connection between the first transport plate and the second transport plate. A number of shock-absorbing springs are evenly distributed between the buffer plate and the second transport plate. One end of the shock-absorbing spring abuts against the second transport plate, and the other end abuts against the buffer plate.

[0005] Preferably, the small-sliding protection plate includes a vertically arranged first connecting plate and an obliquely arranged second connecting plate. The first connecting plate is connected to the transfer machine support, the bottom end of the second connecting plate is placed on the belt conveyor, and a buffer pad is provided at the contact end between the bottom end of the second connecting plate and the belt conveyor.

[0006] Preferably, the first connecting plate is arranged parallel to the bottom plate, and the second connecting plate is arranged parallel to the coal retaining plate.

[0007] Preferably, the coal retaining plate is provided with positioning holes, and screw rods are arranged in the positioning holes. The screw rods penetrate through the coal retaining plate and are screwed onto the second connecting plate of the small chute protection plate.

[0009] Preferably, water coal troughs are symmetrically arranged on the first conveying plate to prevent the accumulation of water coal.

[0010] Preferably, a gap is left between the bottom end of the second conveying plate and the belt conveyor to avoid collision with the coal on the belt conveyor and prevent accumulation.

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

[0012] By arranging a coal unloading device between the unloading port of the transfer machine and the belt conveyor, the drop between the unloading port and the conveyor is reduced. The first conveying plate and the second conveying plate are angularly connected to form a two-stage slope design. Coal falls from the unloading port of the transfer machine onto the first conveying plate. Due to the angle of the first conveying plate, the coal slides onto the buffer plate on the second conveying plate. The buffer plate is designed in a conical shape, and its conical end fits at the connection between the first conveying plate and the second conveying plate, enabling the coal to fall smoothly. When the coal directly falls onto the second conveying plate, the shock-absorbing spring between the buffer plate and the second conveying plate buffers the impact. Subsequently, the coal falls onto the belt conveyor. This can effectively protect the lower belt, extend the service life of the belt, and reduce the frequency of replacing the belt and the coal retaining leather. At the same time, the device can significantly reduce the coal dust generated during coal discharging, with an effect reaching more than 95%. In addition, water coal troughs are arranged on the first conveying plate to prevent the accumulation of water coal, and a gap is provided between the second conveying plate and the belt conveyor to prevent the accumulation of coal and affect normal operation. The device is installed on the small chute protection plate between the transfer machine and the belt conveyor through bolts, which is convenient for disassembly and installation.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment 1: Please refer to Figure 1-2, An embodiment provided by the present utility model: A coal unloading device for the loading head of a conveyor, comprising a loader 1, a belt conveyor 2, and a coal unloading device 4 arranged between the discharge opening of the loader 1 and the belt conveyor 2. The coal unloading device 4 includes a bottom plate 401, a support plate 402, a first conveyor plate 403, a second conveyor plate 405, a coal retaining plate 406, and a buffer plate 407. The bottom plate 401 is symmetrically connected to the small chute protection plates 3 between the discharge opening of the loader 1 and the belt conveyor 2 on the left and right. The rear side of the bottom end of the bottom plate 401 is connected with a support plate 402. The support plate 402 is set in a right triangle. The angle of the support plate 402 supports the first conveyor plate 403, setting the first conveyor plate 403 at an angle to form a first slope, reducing the distance between the loader 1 and the belt conveyor 2, and being able to effectively disperse the impact force of the coal. The inclined ends of the two support plates 402 are connected with the first conveyor plate 403. The first conveyor plate 403 receives the coal and guides it to the second conveyor plate 405. The advantage is that the coal can be smoothly transitioned through the angle design, reducing the impact caused by the drop. Set at the discharge opening of the loader 1, the top end of the first conveyor plate 403 is connected with a second conveyor plate 405 set at an angle. The second conveyor plate 405 receives the coal sliding down from the first conveyor plate 403 and forms a secondary slope with the first conveyor plate 403, further reducing the distance between the loader 1 and the belt conveyor 2, preventing the coal from directly falling on the belt conveyor 2 when falling, causing damage to the belt, and at the same time reducing excessive dust caused by the high drop. The left and right sides of the second conveyor plate 405 are respectively connected with obliquely arranged coal retaining plates 406. The coal retaining plates 406 prevent the coal from leaking or spilling sideways, limiting the position of the coal when falling, enabling it to be smoothly transported onto the belt conveyor 2, reducing coal spillage, and keeping the working face clean. The bottom end of the coal retaining plate 406 is connected with the bottom plate 401. Water coal troughs 404 are symmetrically arranged on the first conveyor plate 403 to prevent the accumulation of water coal, avoid the problem of coal caking caused by water accumulation, and keep the system running normally. There is a gap between the bottom end of the second conveyor plate 405 and the belt conveyor 2 to avoid collision with the coal on the belt conveyor 2 and prevent accumulation. The gap between the bottom end of the second conveyor plate 405 and the belt conveyor 2 prevents coal accumulation, reduces the collision between the coal and the second conveyor plate 405, and maintains the transportation efficiency. When in use, first install the coal unloading device 4 between the loader 1 and the belt conveyor 2. During the falling process of the coal, it first falls on the first conveyor plate 403. Since the first conveyor plate 403 is installed on the inclined end of the triangular support plate 402, forming a primary slope, the coal passes through the slope of the first conveyor plate 403 and falls on the second conveyor plate 405. At the same time, the second conveyor plate 405 and the first conveyor plate 403 form a secondary slope, further reducing the distance between the loader 1 and the belt conveyor 2. Subsequently, during the falling process of the coal, it passes through the resistance of the coal retaining plate 406 and falls on the lower belt conveyor 2.

[0023] Example 2: Please refer to Figure 3 , based on Example 1, it also has the following structure:

[0024] A buffer plate 407 is hinged between the coal blocking plates 406 on both sides. The buffer plate 407 is set in a conical shape, and the conical end fits the connection between the first transport plate 403 and the second transport plate 405. A number of damping springs 408 are evenly distributed between the buffer plate 407 and the second transport plate 405. One end of the damping spring 408 contacts the second transport plate 405, and the other end contacts the buffer plate 407. When in use, since the buffer plate 407 is designed in a conical shape, the conical end fits the connection between the first transport plate 403 and the second transport plate 405, so that the coal can be smoothly transferred to the buffer plate 407 through the first transport plate 403, and when the coal falls directly on the second transport plate 405, the buffer plate 407 resists, and at the same time, one end of the buffer plate 407 rotates, and the other end squeezes the damping spring 408 between the second transport plate 405 to reduce the impact. Since the buffer plate 407 is designed in a conical shape and has a slope, the coal falls on the belt conveyor 2 through the slope.

[0025] Example 3: Please refer to Figure 3 , based on Example 1, it also has the following structure:

[0026] The small walking protection plate 3 includes a first connecting plate set up vertically and a second connecting plate set up obliquely. The first connecting plate is connected to the bracket of the transfer machine 1, and the bottom end of the second connecting plate is set on the belt conveyor 2. A buffer pad is provided at the contact end between the bottom end of the second connecting plate and the belt conveyor 2. The buffer pad is arranged at the place where the bottom end of the second connecting plate contacts the belt conveyor 2. The advantage is that it absorbs impact force, reduces friction and protects the belt conveyor 2.

[0027] The first connecting plate is arranged parallel to the bottom plate 401, and the second connecting plate is arranged parallel to the coal blocking plate 406.

[0028] A positioning hole is opened on the coal blocking plate 406, and a screw is arranged in the positioning hole. The screw passes through the coal blocking plate 406 and is screwed on the second connecting plate of the small protective plate 3 to ensure the stability and precise positioning of the coal blocking plate 406, and connects the coal blocking plate 406 and the small protective plate 3 to form a whole, ensuring a stable connection.

[0029] The bottom plate 401 is provided with a plurality of connection holes, in which threaded rods are arranged. The threaded rods penetrate the bottom plate 401 and are screwed into the threaded holes preset on the first connection plate, so as to realize a firm connection between the bottom plate 401 and the first connection plate and ensure the stability of the overall device.

[0030] The above are only embodiments of the present utility model, and common knowledge such as specific structures and characteristics known in the solution is not described in detail herein. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be construed as limiting the claimed rights involved.
