Description

Technical Field

[0001] This utility model belongs to the field of underground coal mining and transportation, specifically relating to a mechanism for connecting a scraper conveyor and a transfer conveyor with a spray device. Background Technology

[0002] During operation, scraper conveyors generate a large amount of coal dust due to coal crushing and friction. If this dust is not effectively controlled in a timely manner, it increases the risk of dust explosions, posing a serious safety hazard to coal mine production. Furthermore, dust permeates the working environment, severely reducing visibility. This affects operators' ability to observe the equipment's operating status, increases the risk of operational errors, and can easily lead to equipment malfunctions, collisions, and other safety accidents.

[0003] The working face is the area with the most dust, but both the coal and gangue are exposed, including the coal face, the cutting rollers of the mining machine in direct contact with the coal face, and the open-face scraper conveyor. Therefore, dust at the working face cannot be completely avoided; it can only be mitigated through various measures. The machine roadway is better than the working face, but the point where the scraper conveyor unloads to the transfer conveyor is the only open point of coal flow in the machine roadway. Furthermore, the coal and gangue thrown from the scraper conveyor head to the transfer conveyor unloading port generate dust, requiring measures to reduce it. Patent CN217946999U describes a spray device on the scraper head guard plate, and patent CN209596798U describes a spray device on the transfer conveyor head. However, current technology cannot guarantee dust suppression across the entire area from the scraper conveyor head to the transfer conveyor unloading port, nor can it adjust the spray height and angle to achieve better spraying effects under different environmental conditions. Summary of the Invention

[0004] This utility model provides a mechanism for connecting a scraper conveyor and a transfer conveyor with a spraying device.

[0005] The purpose of this utility model is achieved in the following manner: a scraper conveyor and transfer conveyor connection mechanism with a spraying device, including a transfer conveyor unloading port chute and a scraper conveyor head connected to the transfer conveyor unloading port chute, a head baffle is provided on one side of the scraper conveyor head, and an unloading port baffle is provided on the transfer conveyor unloading port chute; a spraying mechanism is provided on the head baffle of the scraper conveyor head; a spray mounting frame is rotatably provided on the top of the unloading port baffle of the transfer conveyor unloading port chute, and a spraying mechanism that sprays downwards at an angle is provided on the spray mounting frame; a linear drive mechanism that drives the spray mounting frame to rotate is hinged between the spray mounting frame and the unloading port baffle.

[0006] The angle between the spray surface of the spray mechanism on the spray mounting bracket and the vertical surface of the unloading port baffle is between 100 and 160 degrees.

[0007] The linear drive mechanism is a hydraulic cylinder. A mounting connecting plate is fixedly installed on the top of the unloading port baffle. The spray mounting frame and the mounting connecting plate are rotatably connected by a rotating hinge. The piston rod and cylinder body of the hydraulic cylinder are respectively hinged to the spray mounting frame and the mounting connecting plate.

[0008] The spraying mechanism includes a mounting plate and a hollow mounting tube fixed to the mounting plate; the mounting plate is provided with mounting holes, the back of the mounting tube is provided with a water inlet, and the front of the mounting tube is provided with at least two spray nozzles along its length; the head baffle is provided with a first fixing hole at the position corresponding to the mounting hole; the spray mounting bracket is provided with a second fixing hole at the position corresponding to the mounting hole; both the head baffle and the spray mounting bracket are provided with spray nozzle receiving holes at the positions corresponding to the spray nozzles; the spraying mechanism is fixed to the back of the head baffle and the unloading port baffle respectively, and the spray nozzles spray outwards through the corresponding spray nozzle receiving holes.

[0009] The height of the spray mechanism on the headstock baffle is adjustable: at least two sets of first fixing holes and spray nozzle receiving holes are provided on the headstock baffle corresponding to the spray mechanism.

[0010] Compared to existing technologies, the spray mechanism at the scraper conveyor head of this invention sprays dust onto the scraper conveyor chain track. The spray mechanism at the unloading port of the transfer conveyor sprays at the unloading point of the scraper conveyor head sprocket. This two-directional spraying provides more comprehensive dust suppression. Furthermore, the spray mechanism on the transfer conveyor is tilted downwards, and the spray angle is adjustable, allowing for more precise adaptation to the on-site environment and achieving better dust suppression results.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. Figure 1-6As shown, a scraper conveyor and transfer conveyor connection mechanism with a spraying device includes a transfer conveyor unloading chute 4 and a scraper conveyor head 3 connected to the transfer conveyor unloading chute 4. A head baffle 2 is provided on one side of the scraper conveyor head 3, and an unloading baffle 6 is provided on the transfer conveyor unloading chute 4. A spraying mechanism 1 is provided on the head baffle 2 of the scraper conveyor head 3. A spray mounting frame 5 is rotatably mounted on the top of the unloading baffle 6 of the transfer conveyor unloading chute 4. The spray mounting frame 5 is equipped with the downward-sloping spraying mechanism 1. A linear drive mechanism 54 that drives the spray mounting frame 5 to rotate is hinged between the spray mounting frame 5 and the unloading baffle 6. Specifically, the scraper conveyor head 3 and the transfer conveyor tail are preferably vertically arranged, but can also be at a certain angle as needed. Coal blocks fall from the scraper conveyor head 3 into the transfer conveyor unloading chute 4 and continue to be transported forward. The unloading baffle 6 is located on the side of the unloading chute 4 away from the scraper conveyor. The length direction of the unloading port baffle 6 is consistent with the length direction of the unloading port chute 4 of the transfer machine. The spray nozzles 13 of the two spray mechanisms 1 are connected to a water source through water pipes. The water source adopts the existing dust suppression water source of the scraper conveyor. This part adopts existing technology and will not be described in detail. In this utility model, corresponding spray mechanisms 1 are respectively set on the head baffle 2 of the scraper conveyor and the unloading port baffle 6 of the transfer machine. The spray mechanism 1 of the head baffle is aimed at the scraper conveyor chain track to spray dust suppression. The spray mechanism 1 of the unloading port is aimed at the unloading point of the sprocket of the scraper conveyor head 3. The spraying in two directions achieves more comprehensive dust suppression. Moreover, the spray mechanism 1 of the unloading port is set at an angle downward, and the spray angle can be adjusted, which can more accurately adapt to the on-site environment and achieve better dust suppression effect.

[0020] Furthermore, the angle between the spray surface of the spray mechanism 1 on the spray mounting bracket 5 and the vertical surface of the unloading port baffle 6 is between 100 and 160 degrees. It can be adjusted according to site requirements.

[0021] Furthermore, the linear drive mechanism 54 is a hydraulic cylinder, and a mounting connecting plate 8 is fixedly installed on the top of the unloading port baffle 6. The spray mounting frame 5 and the mounting connecting plate 8 are rotatably connected via a rotating hinge 55. The piston rod and cylinder body of the hydraulic cylinder are respectively hinged to the spray mounting frame 5 and the mounting connecting plate 8. This utility model can adjust the spray angle by extending and retracting the hydraulic cylinder piston rod. Moreover, by setting the mounting connecting plate 8, the hydraulic cylinder and the rotating hinge 55 can be placed between the mounting connecting plate 8 and the unloading port baffle 6. Compared with the structure installed on the unloading port baffle 6, the structure of this utility model is more convenient to install, disassemble, and process. Specifically, the mounting connecting plate 8 is also provided with a mounting connection hole 81 that connects to the unloading port baffle 6. The mounting connection hole 81 is preferably an elongated hole, thereby allowing for fine adjustment of the front and rear positions. A corresponding hole is provided at the top of the unloading port baffle 6.

[0022] Furthermore, the spray mechanism 1 includes a mounting plate and a hollow mounting tube 14 fixed to the mounting plate; the mounting plate is provided with mounting holes 11, the back of the mounting tube 14 is provided with a water inlet 12, and the front of the mounting tube 14 is provided with at least two spray nozzles 13 along its own length; the head baffle 2 is provided with a first mounting hole 21 corresponding to the mounting hole 11; the spray mounting bracket 5 is provided with a second fixing hole 52 corresponding to the mounting hole 11; both the head baffle 2 and the spray mounting bracket 5 are provided with spray nozzle receiving holes 7 corresponding to the spray nozzles 13; the spray mechanism 1 is fixed to the back of the head baffle 2 and the spray mounting bracket 5 respectively, and the spray nozzles 13 spray outwards through the corresponding spray nozzle receiving holes 7. The cross-sectional shape of the mounting tube 14 can be triangular, and the back and the mounting plate can be the same plate. Spray nozzles 13 are provided on either of the other two sides. The shape of the spray nozzles 13 is set as needed. The mounting hole 11 corresponds to the first fixing hole 21 on the head baffle 2 and the second fixing hole 52 on the spray mounting bracket 5, and the spray device is installed by bolts or the like. The front of the mounting pipe 14 is connected to the back of the head baffle 2 or the spray mounting bracket 5 by bolts or other fixing mechanisms. The front of the head baffle 2 and the front of the unloading port baffle 6 face the direction where there is coal. The spray mechanism 1 can adopt a common existing structure. The spray nozzle 13 can be concave hemispherical in shape. After the high-pressure water is sprayed out from the spray nozzle 13, it will automatically be shaped into a hemispherical spray due to the shape of the spray nozzle 13. The spray nozzle 13 can also be other existing shapes. A connector is provided at the water inlet 12. After the end of the high-pressure water pipe is connected to the water inlet 12, water is injected. After the pressurized water fills the mounting pipe 14, it is atomized and sprayed out from the spray nozzle 13.

[0023] Furthermore, the height of the spray mechanism 1 on the headstock baffle 2 is adjustable: at least two sets of first fixing holes 21 and spray nozzle receiving holes 7 corresponding to the spray mechanism 1 are provided on the headstock baffle 2. The spray mechanism 1 can have at least two fixed positions in the height direction, and its height on the headstock baffle 2 can be adjusted according to actual conditions. The headstock baffle 2 is also provided with a third fixing hole 2323 for fixing the headstock baffle 2 to the transfer machine head.

[0024] In practice: High-pressure water is introduced into the mounting pipe 14 of the spray head through the inlet 12 of the two spray mechanisms 1 via water pipes, and then sprayed out through the spray nozzle 13. The water then falls into the overlapping space through the spray nozzle receiving hole 7 of the spray head baffle 2 and the spray mounting frame 5, achieving multi-directional dust suppression. When the angle of the spray mechanism 1 needs to be adjusted, the hydraulic cylinder of the linear drive mechanism 54 extends and retracts, causing the spray mounting frame 5 and the spray mechanism 1 fixed thereon to rotate.

[0025] The technical features of the embodiments described above can be combined in any way, and as long as there is no contradiction in the combination of these technical features, they should all be considered within the scope of this specification. Without departing from the overall concept of this utility model, any equivalent substitutions or modifications made to the technical solution of this utility model, as well as any changes and improvements, should also be considered within the protection scope of this utility model.
