Description

Technical Field

[0001] This utility model relates to the technical field of spray devices for transfer machine heads, and in particular to a spray device for a transfer machine head in a fully mechanized mining face. Background Technology

[0002] In the production system of fully mechanized coal mining faces in underground coal mines, the transfer head is a key connecting device that links the scraper conveyor (coal outlet end of the coal mining machine) and the belt conveyor (coal transport end). It undertakes the task of transitioning coal from short-distance transfer to long-distance transport. Due to the height difference (usually 1-3m) of coal during the transfer process, and the high coal flow velocity and intense particle collision at the transfer head, a large amount of dust is easily generated (dust concentration can reach 500-1500mg / m³). The existing spraying device for the transfer machine head in fully mechanized mining faces has several drawbacks. Traditional spraying devices are often installed on fixed brackets, with fixed heights that are either not adjustable or require cumbersome adjustments. The fixed-height spray head cannot accurately target the core dust-generating area. The spray angle of traditional spraying devices is often fixed, or requires manual adjustment by turning bolts. The adjustment process requires stopping the machine and cannot adapt to changes in the dust diffusion direction in real time. Therefore, these technical problems need to be solved.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Example: See Figures 1 to 8 This utility model discloses a spraying device for a fully mechanized mining face transfer machine head, comprising telescopic rods 2 installed opposite each other on both sides of the transfer machine head. The bottom ends of the telescopic rods 2 are fixed to fixed plates 1, which are bolted to fixed frames on both sides of the transfer machine head. An angle adjustment mechanism is installed at the top of the telescopic rods 2 in the vertical direction of the fixed plates 1. A spraying mechanism is installed between the angle adjustment mechanisms, and a fixing mechanism is mounted on the angle adjustment mechanism. Through the telescopic rods 2, fixed plates 1, angle adjustment mechanisms, spraying mechanisms, and fixing mechanisms, the overall framework of the spraying device for the fully mechanized mining face transfer machine head is easily constructed, achieving stable fixation of the device on the transfer machine head, and providing a functional basis for spray angle adjustment and spraying operations. The telescopic rod 2 has a T-slot vertically formed in the center of its telescopic end. A fixing screw 14 is installed in the T-slot. The end of the fixing screw 14 is slidably installed in the T-slot, and the other end of the screw passes through the telescopic rod 2 and is connected to a fixing nut by a thread. The T-slot, fixing screw 14, and fixing nut of the telescopic rod 2 facilitate the fixation of the telescopic rod 2's telescopic length, ensuring the stability of the spray mechanism's installation height and preventing the spray position from shifting due to the telescopic rod 2 becoming loose during use. Adjusting plates 5 and L-shaped positioning plates are respectively fixed to the telescopic rods 2 on both sides. The adjusting plates 5 and L-shaped positioning plates provide a mounting and rotation carrier for the rotating rod 6 of the spray mechanism, supporting the stable assembly of the spray components and providing structural support for subsequent spray angle adjustments.

[0015] In this utility model, the spraying mechanism includes a rotating rod 6 rotatably mounted between the adjusting plate 5 and the L-shaped positioning plate. A spraying plate 3 is sleeved on the rotating rod 6. Spray heads 4 are equidistantly mounted on one end of the spraying plate 3. Water guide holes are correspondingly opened in the spraying plate 3 inside the spray heads 4. A water guide pipe 7 is connected to one side of the spraying plate 3 corresponding to the water guide hole. The water guide pipe 7 is fixed to one side of the telescopic end of the telescopic rod 2 by a fixing ring. Through the rotating rod 6, spraying plate 3, spray heads 4, water guide holes, water guide pipe 7, and fixing ring, water is easily transported through the water guide pipe 7 and distributed to the spray heads 4 through the water guide holes to achieve dust reduction or cooling of the transfer machine head. At the same time, the rotating rod 6 can assist in adjusting the spraying direction. The angle adjustment mechanism includes a telescopic cylinder 9 sleeved on the rotating rod 6 between the adjusting plates 5. The telescopic end of the telescopic cylinder 9 is fixed to the adjusting rod 10. The adjusting rod 10 is movably installed at one end in the adjusting groove 12 on the adjusting plate 5. Through the telescopic cylinder 9, adjusting rod 10, adjusting groove 12, and rotating rod 6, the telescopic cylinder 9 can be used to move the adjusting rod 10 within the adjusting groove 12, thereby driving the rotating rod 6 to rotate and realize flexible adjustment of the spray angle. The fixing mechanism includes a movable groove 11 corresponding to the adjusting rod 10 on one side of the spray plate 3. Pull rods 8 are sleeved at both ends of the adjusting rod 10, and a telescopic spring 13 is installed inside the telescopic cylinder 9 in the middle of the adjusting rod 10. The two ends of the telescopic spring 13 are fixed to the inner wall of the telescopic cylinder 9 and the telescopic end, respectively. Through the movable groove 11, pull rod 8, telescopic spring 13, adjusting rod 10, and telescopic cylinder 9, the elastic force of the telescopic spring 13 can be used to fix the position of the adjusting rod 10 and maintain a stable spray angle.

[0016] Working principle: When using this utility model, firstly, the fixing plate 1 is bolted to the fixed frame of the transfer machine head in the fully mechanized mining face. Then, according to the actual height requirements of the transfer machine head, the telescopic end of the telescopic rod 2 is stretched or compressed. After the height is adjusted to the correct position, the position of the telescopic end is locked by the squeezing force between the nut and the outer wall of the telescopic rod 2, preventing the telescopic rod 2 from extending or retracting on its own due to vibration or gravity during operation, thus ensuring a stable spray height. Then, the external high-pressure water source is transported to the spray plate 3 through the water guide pipe 7, and is converted into fine water mist through the corresponding spray head 4 to achieve dust capture and settling. Then, by manually pulling the pull rod 8, the telescopic cylinder 9 is extended, thereby adjusting the position of the adjusting rod 10 in the adjusting groove 12, thereby changing the spray angle of the spray head 4. At the same time, when the pull rod 8 is released, the telescopic spring 13 contracts, thereby achieving a stable locking of the spray angle and ensuring that the water mist always covers the target dust-suppressing area.

[0017] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
