Description

Technical Field

[0001] This invention relates to the field of coal feeder technology, and more specifically to a modular coal feeder for mining. Background Technology

[0002] A coal feeder is a type of coal conveying machinery, mainly used for the transfer of coal. Existing coal feeders include reciprocating coal feeders and chain plate coal feeders. Due to the many disadvantages of reciprocating coal feeders, they are gradually being phased out, and chain plate coal feeders are now the most commonly used type.

[0003] When a chain plate feeder is in operation, coal falls from above and is then transported by the feeder to a designated location or equipment. However, coal can sometimes get stuck, causing the transport components to malfunction, leading to motor damage or even burnout, thus affecting work efficiency and increasing transportation costs. Furthermore, the impact of coal falling onto the feeder can damage its transport components, shortening its lifespan and increasing maintenance costs. Summary of the Invention

[0004] In order to overcome the problems mentioned in the background art, the present invention provides a modular coal feeder for mining.

[0005] The technical solution of the present invention is as follows:

[0006] A modular coal feeder for mining includes a base plate with a control terminal mounted on it. Symmetrical first mounting seats are fixedly connected to the base plate, and uniformly distributed first load-bearing rollers are rotatably connected between the symmetrical first mounting seats. Movable plates are mounted on the uniformly distributed first load-bearing rollers, and the movable plates contact and engage with the first load-bearing rollers. The base plate is equipped with a locking device for locking the movable plates, which are in a limiting engagement with the first mounting seats. Symmetrical mounting frames are fixedly connected to the movable plates, and symmetrical rotating shafts are rotatably connected between the symmetrical mounting frames. Drive rollers are fixedly connected to the rotating shafts, and the symmetrical drive rollers communicate with each other. A chain plate is wound around the sprocket. A second load-bearing roller is evenly distributed and rotatably connected between symmetrical mounting frames. The second load-bearing roller is in contact with the chain plate. A first support rod is fixed to the moving plate. A geared motor is fixed to the first support rod. A symmetrical rotating pressure plate is fixed to the output shaft of the geared motor. A first transmission housing is fixed to the shaft near the geared motor. A symmetrical fixed pressure plate is set inside the first transmission housing. A stop block is fixed to the bottom plate. A hydraulic rod is fixed to the stop block. The telescopic end of the hydraulic rod is fixed to the moving plate. The locking device, the geared motor and the hydraulic rod are all electrically connected to the control terminal.

[0007] As an improvement to the above solution, a second mounting seat is detachably installed on the chain plate and is symmetrically and evenly distributed. The second mounting seat is slidably connected to a sliding block. An elastic element is provided between the sliding block and the adjacent second mounting seat. A buffer rod is rotatably connected between the symmetrical sliding blocks. A gear is fixed to one end of the buffer rod.

[0008] As an improvement to the above scheme, a symmetrical second mounting base and its components are arranged on adjacent plates on the chain plate.

[0009] As an improvement to the above solution, the buffer rod is made of an elastic material with strong resistance to deformation.

[0010] As an improvement to the above solution, the surface of the buffer rod is provided with protrusions to increase the friction between the buffer rod and the coal.

[0011] As an improvement to the above scheme, the first transmission housing is sealed to the rotating pressure plate, and the fixed pressure plate is sealed to the output shaft of the geared motor. The first transmission housing is provided with centrally symmetrical through holes. The cavity formed by the rotating pressure plate, the first transmission housing, and the fixed pressure plate, and the cavity communicating with the through holes is filled with liquid. The first transmission housing is rotatably connected to the fixed housing, and the fixed housing is fixedly connected to the adjacent mounting bracket. The centrally symmetrical through holes are all connected to the fixed housing. A second support rod is fixedly connected to the side of the base plate near the gear. The second support rod is fixedly connected to the second transmission housing, which is filled with liquid. The second transmission housing is connected to the fixed housing through a hose. The second transmission housing is slidably connected to a transmission slide rod. A tension spring is provided between the transmission slide rod and the second transmission housing. The transmission slide rod is fixedly connected to a rack that cooperates with the gear transmission.

[0012] As an improvement to the above scheme, the length of the rack is equal to the distance between the symmetrical axis of rotation.

[0013] As an improvement to the above solution, a limit rod is fixed to the mounting bracket near the gear, and the limit rod and the buffer rod are in a limiting engagement.

[0014] As an improvement to the above solution, the movable plate is fixedly connected to an electric push rod that is electrically connected to the control terminal via a fixed plate. The telescopic part of the electric push rod is fixedly connected to a transmission block, and the transmission block is hinged to a scraper.

[0015] As an improvement to the above solution, the telescopic end of the electric push rod is in contact with the scraper.

[0016] The beneficial technical effects of this invention are:

[0017] This invention causes misalignment between large pieces of coal that are stuck by moving the moving plate and all its parts, thereby disrupting their structure and enabling the equipment to continue transporting continuously.

[0018] The impact of falling coal on the equipment is reduced by using a buffer bar, thereby protecting the important parts of the equipment, extending the service life of the equipment, reducing the workload of equipment maintenance, and lowering the maintenance cost of the equipment.

[0019] By rotating the buffer rod as the moving plate moves, the coal in the adjacent part is agitated, causing relative displacement between the coal, thereby providing space for the large pieces of coal that are stuck to move, and thus allowing the stuck coal to separate more quickly, so as to achieve the effect of quickly restoring normal working state.

[0020] By moving the buffer rod, the coal stuck between it and the chain plate falls off, preventing it from affecting the normal operation of the equipment. After the coal falls onto the moving plate, a scraper cleans the coal off the surface of the moving plate to prevent excessive coal accumulation on the moving plate from affecting the operation of the equipment.

[0033] Example 1:

[0034] A modular coal feeder for mining, such as Figures 1-4As shown, the device includes a base plate 1, on which a control terminal is mounted. Two symmetrical first mounting seats 2 are fixedly connected to the base plate 1. A first load-bearing roller 3, evenly distributed horizontally, is rotatably connected between the two first mounting seats 2 to reduce friction when a moving plate 4 moves. A moving plate 4 is mounted on the evenly distributed first load-bearing roller 3, and the moving plate 4 contacts and engages with the first load-bearing roller 3. A locking device is provided between the moving plate 4 and the base plate 1 to fix the moving plate 4. The moving plate 4 is also limited to the two first mounting seats 2 to prevent displacement. Two symmetrical mounting brackets 5 are fixedly connected to the upper side of the moving plate 4. Two symmetrical rotating shafts 6 are rotatably connected between the two mounting brackets 5. A transmission roller 7 is fixedly connected to the rotating shaft 6. A chain plate 8 is wound around the two transmission rollers 7 via a sprocket. The mounting brackets 5 are rotatably connected by evenly distributed second load-bearing rollers 9, which provide support for the chain plate 8 and prevent the chain plate 8 from being damaged due to excessive load. The second load-bearing rollers 9 are in contact with the lower side of the upper part of the chain plate 8. The front side of the moving plate 4 is fixedly connected to a first support rod 10. The upper side of the first support rod 10 is fixedly connected to a reduction motor 11. The output shaft of the reduction motor 11 is fixedly connected to two centrally symmetrical rotating pressure plates 12. The front end of the left rotating shaft 6 is fixedly connected to a first transmission housing 13. The first transmission housing 13 is provided with two centrally symmetrical fixed pressure plates 1301. The right side of the base plate 1 is fixedly connected to a stop block 14. The left side of the stop block 14 is fixedly connected to a hydraulic rod 15. The telescopic end of the hydraulic rod 15 is fixedly connected to the right side of the moving plate 4. The locking device, the reduction motor 11 and the hydraulic rod 15 are all electrically connected to the control terminal.

[0035] like Figure 5 and Figure 6 As shown, several symmetrical second mounting seats 16 are detachably installed on the chain plate 8. Each pair of symmetrical second mounting seats 16 and their components are mounted on adjacent plates on the chain plate 8. A sliding block 17 is slidably connected inside the second mounting seat 16. An elastic element 18 is provided between the sliding block 17 and the adjacent second mounting seat 16. The elastic element 18 is located on the lower side of the sliding block 17. A buffer rod 19 is rotatably connected between two symmetrical sliding blocks 17. The buffer rod 19 is made of an elastic material with strong resistance to deformation and is used to buffer the falling coal. The surface of the buffer rod 19 is provided with protrusions to increase the friction between the buffer rod 19 and the coal, so that the buffer rod 19 can better agitate the nearby coal and provide space for the movement of large pieces of coal. A gear 20 is fixedly connected to the front end of the buffer rod 19.

[0036] like Figure 3 and Figure 5As shown, the first transmission housing 13 is sealed to the rotating pressure plate 12 to prevent liquid leakage within the first transmission housing 13. The fixed pressure plate 1301 is sealed to the output shaft of the geared motor 11 to prevent liquid leakage within the first transmission housing 13. The first transmission housing 13 has two centrally symmetrical through holes. The two cavities in the cavity formed by the rotating pressure plate 12, the first transmission housing 13, and the fixed pressure plate 1301, which communicate with the through holes, are filled with liquid. An annular fixed housing 1302 is rotatably connected to the outer side of the first transmission housing 13. The fixed housing 1302 is fixedly connected to the front side of the adjacent mounting bracket 5. Both through holes are connected to the fixed housing 1302. The base plate 1 is connected to the front of the gear 20 with an L-shaped second support rod 21. The upper side of the second support rod 21 is fixed with a second transmission housing 22, which is filled with liquid. The left side of the second transmission housing 22 is connected to the right side of the fixed housing 1302 through a hose. An L-shaped transmission slide rod 23 is slidably connected inside the second transmission housing 22. A tension spring 24 is provided between the transmission slide rod 23 and the second transmission housing 22. A rack 25 that drives the gear 20 is fixed to the rear side of the transmission slide rod 23. The length of the rack 25 is equal to the distance between the symmetrical rotating shaft 6, so that the gear 20 drives the rack 25 when it is located on the upper side of the chain plate 8.

[0037] When using this equipment to transport coal, first set up the equipment at the point of use. Then, the coal falls from the hopper to the upper side of the equipment through the funnel. As the coal falls, it first contacts the buffer rod 19 located below the funnel. The buffer rod 19 moves downwards upon impact with the coal, compressing the adjacent elastic element 18. During this process, most of the kinetic energy of the coal is reduced, and the impact force is reduced when it contacts the chain plate 8, thereby protecting the integrity of the chain plate 8 and extending the service life of the equipment. While the buffer rod 19 is being impacted by the coal, the buffer rod 19 also undergoes a certain deformation, thereby absorbing some of the kinetic energy of the coal. When the coal gradually falls and accumulates between the funnel and the equipment until it reaches saturation, the coal stops falling.

[0038] At this time, the control terminal controls the start of the reduction motor 11. The output shaft of the reduction motor 11 drives the two rotating pressure plates 12 to rotate counterclockwise. At this time, the two rotating pressure plates 12 squeeze the liquid in their adjacent cavities. Because the elastic coefficient of the tension spring 24 is large, only a very small part of the liquid enters the fixed shell 1302 through the through hole, and then enters the second transmission shell 22 through the hose. The liquid pressure in the second transmission shell 22 increases, which pushes the transmission slide rod 23 upward a small section. The transmission slide rod 23 drives the rack 25 to move upward together. At this time, the rack 25 will not mesh with the gear 20.

[0039] Simultaneously, rotating the pressure plate 12 drives the fixed pressure plate 1301 through the compression of the liquid. The fixed pressure plate 1301 drives the first transmission shell 13 to rotate counterclockwise. The first transmission shell 13 drives the rotating shaft 6 on the left to rotate. The rotating shaft 6 drives the adjacent transmission roller 7 to rotate. The transmission roller 7 drives the chain plate 8 to rotate counterclockwise through the sprockets set on the front and rear sides. The chain plate 8 drives the rotating shaft 6 and the transmission roller 7 on the right to rotate. At this time, the chain plate 8 drives the coal on it to move to the left, and then the coal is continuously discharged from the left side of the equipment, thus completing the coal feeding process.

[0040] During equipment operation, when a large piece of coal gets stuck between the funnel and the equipment, the chain plate 8 slows down or even stops due to the coal jamming. At this time, the reduction motor 11 still drives the rotating pressure plate 12 to continue rotating. The liquid between the rotating pressure plate 12 and the fixed pressure plate 1301 continues to be compressed and enters the second transmission shell 22 through the fixed shell 1302 and the hose, pushing the transmission slide rod 23 to move upward. When the transmission slide rod 23 drives the rack 25 to mesh with the upper gear 20, the control terminal controls the locking device to unlock the moving plate 4. At the same time, the control terminal controls the hydraulic rod 15 to start, reciprocatingly pushing and pulling the moving plate 4, causing the moving plate 4, its parts, and the coal to move to a certain extent. This causes misalignment between the jammed large pieces of coal, destroying their structure and allowing the equipment to continue continuous transportation.

[0041] When the hydraulic rod 15 moves the moving plate 4 and its parts, the rack 25 is fixed and meshes with the gear 20 on the upper side. Therefore, the gear 20 will also rotate as it moves with the buffer rod 19, thereby driving the buffer rod 19 to rotate. When the buffer rod 19 rotates, it will agitate the coal in the adjacent part, so that the finer coal fills the gaps in the vicinity, thereby providing space for the large pieces of coal that are stuck to move, and thus allowing the stuck coal to separate more quickly, so as to achieve the effect of quickly restoring normal working state.

[0042] When the stuck coal is separated and the equipment returns to normal operation, the resistance on the chain plate 8 decreases. Under the action of the tension spring 24, the transmission slide rod 23 drives the rack 25 to move downward and pushes the liquid in the second transmission housing 22 back into the first transmission housing 13. At this time, the rack 25 separates from the gear 20, and the gear 20 stops rotating. At this time, the control terminal controls the hydraulic rod 15 to stop working and activates the locking device to lock the moving plate 4 again. After the equipment has finished working, the control terminal controls the reduction motor 11 to shut down.

[0043] Example 2:

[0044] Based on Example 1, such as Figure 7As shown, an L-shaped limiting rod 26 is fixed to the left side of the rear side of the front mounting frame 5. The limiting rod 26 is engaged with the buffer rod 19 to limit the movement of the buffer rod 19, thereby causing the coal stuck between the buffer rod 19 and the chain plate 8 to fall off.

[0045] like Figure 8 As shown, an electric push rod 27, which is electrically connected to the control terminal, is fixed to the upper right side of the movable plate 4 via a fixed plate. The telescopic end of the electric push rod 27 is to the left. A transmission block 28 is fixed to the telescopic part of the electric push rod 27. A scraper 29 is hinged to the left side of the transmission block 28. The telescopic end of the electric push rod 27 contacts and cooperates with the scraper 29, so that when the scraper 29 moves to the left, it pushes the coal, and when it moves to the right, it does not move the coal.

[0046] During equipment operation, when coal gets stuck between the buffer rod 19 and the chain plate 8, after the buffer rod 19 rotates to the lower left side of the chain plate 8, it loses the pressure of the coal and resets under the action of the elastic element 18. At this time, most of the stuck coal is released and falls between the buffer rod 19 and the chain plate 8. It and the still stuck coal continue to move with the buffer rod 19 and the chain plate 8. When the buffer rod 19 moves to contact the limit rod 26, it moves downward under the pressure of the limit rod 26, and the distance between the buffer rod 19 and the chain plate 8 becomes farther and farther. Thus, the coal stuck between the buffer rod 19 and the chain plate 8 falls onto the moving plate 4. At this time, the control terminal controls the electric push rod 27 to start, which continuously extends and retracts during equipment operation, driving the push rod 27 set on the chain plate 4. The transmission block 28 and scraper 29 reciprocate. When the electric push rod 27 extends, it drives the transmission block 28 and scraper 29 to move to the left. The extension end of the electric push rod 27 abuts against the scraper 29, keeping the scraper 29 perpendicular to the moving plate 4. Then, it pushes the coal falling from the moving plate 4 down. When the electric push rod 27 retracts, it drives the scraper 29 to move to the right. When there is coal on the right side of the scraper 29, the coal blocks the lower side of the scraper 29, causing the scraper 29 to rotate around its connection with the transmission block 28, thus preventing the scraper 29 from moving the coal to the right. When the electric push rod 27 extends again, it pushes the coal off the moving plate 4. When the equipment finishes working, the control terminal controls the electric push rod 27 to stop working.
