[0002] During the transportation of railway bulk coal, due to the forward speed of the coal transport train and the action of wind, the coal powder particles on its surface are easily blown off the vehicle body. Therefore, it is crucial to suppress the dust during railway bulk coal transportation.

[0003] In the prior art, in order to perform dust suppression treatment on the coal transport train, it is generally necessary to use a dust suppressant to spray the coal surface through an atomizing nozzle to solidify the coal surface and form a protection layer to prevent coal ash from escaping. However, in the actual use process, the dust suppression atomizing nozzle is exposed to the outside for a long time, and there is a lot of dust in the external environment. Affected by the use environment, some dust accumulates at the output end of the nozzle, resulting in nozzle blockage. Therefore, the utility model proposes a swing arm type quick spraying device for dust suppressant. Summary of the Utility Model

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1 - 3 , in the embodiment of the present invention, a swing-arm type quick spraying device for dust suppressant includes a vertical pole 1, the top of the vertical pole 1 is rotatably connected with a swing arm 2, and a transmission mechanism 3 arranged on the vertical pole 1 and the swing arm 2;

[0030] The transmission mechanism 3 includes a transmission unit and a reset unit;

[0031] The transmission unit is used to automatically open the atomizing nozzle below the swing arm 2;

[0032] The reset unit is used to always give the movable block 304 a thrust in one direction;

[0033] The transmission unit includes a sealing plate 301, a guide block 302, an abutting block 303, a movable block 304, and a pulling block 305;

[0034] The sealing plate 301 is axially slidably installed at the bottom end of the swing arm 2, and the sealing plate 301 is used to protect the atomizing nozzle at the bottom of the vertical pole 1;

[0035] The guide block 302 is fixed to the top end of the sealing plate 301 and extends into the interior of the swing arm 2, and the guide block 302 is used to provide guidance for the movement of the sealing plate 301;

[0036] The abutting block 303 is fixed to the top end of the vertical pole 1, and the abutting block 303 is used to provide an upward thrust for the rotating movable block 304;

[0037] The movable block 304 is vertically slidably installed on the outer wall of the vertical rod of the swing arm 2, and the movable block 304 is used to drive the pulling block 305 to move upward;

[0038] The pulling block 305 is rotatably connected to the end of the movable block 304, and the pulling block 305 is used to push the sealing plate 301 to axially move;

[0039] The reset unit includes a positioning rod 306 and a spring 307;

[0040] The positioning rod 306 is fixed to the inner wall of the vertical rod of the swing arm 2 and penetrates through the protruding part of the movable block 304. The positioning rod 306 is used to guide the vertical movement of the movable block 304.

[0041] Both ends of the spring 307 are respectively clamped to the inner wall of the swing arm 2 and the outer wall of the protruding part of the movable block 304. The spring 307 is used to always provide a downward elastic thrust to the movable block 304.

[0042] In this embodiment: When using this device, when dust suppression treatment is required for coal blocks, the driving motor connected by the vertical rod 1 and the swing arm 2 drives the swing arm 2 to rotate by 90 degrees, so that the atomizing nozzle at the bottom of the swing arm 2 moves above the train carriage filled with coal blocks. During the rotation of the swing arm 2, the movable block 304 at the bottom of the swing arm 2 rotates along with the rotation of the swing arm 2. The rotating movable block 304 will contact the inclined surface at the bottom end of the abutting block 303, giving the movable block 304 an upward moving thrust. The movable block 304 moves upward along the outer wall of the positioning rod 306 and gives the spring 307 a squeezing force. The upward moving movable block 304 will synchronously drive one end of the pulling block 305 to move upward. Then, the sealing plate 301 connected to the other end of the pulling block 305 will move under the moving thrust from the pulling block 305, thereby driving the sealing plate 301 to move away from each other along the bottom end of the swing arm 2 through the guiding block 302. When the guiding block 302 moves to the maximum distance, the top end of the abutting block 303 will also be docked with the bottom end of the movable block 304, and no longer give the movable block 304 an upward thrust. Then, at this time, the coal blocks can be subjected to dust suppression treatment through the atomizing nozzle, achieving the protection of the atomizing nozzle when the atomizing nozzle is not in use, and automatically opening the atomizing nozzle under the swing arm 2 when the atomizing nozzle is needed, reducing the influence of dust in the environment on the atomizing nozzle and avoiding the situation of atomizing nozzle blockage.

[0043] Please refer specifically to Figures 1 - 3 The outer wall of the swing arm 2 is integrally in an "L" - shaped structure. The inner wall of the swing arm 2 is formed with a vertical moving chute for the protruding part on the outer wall of the movable block 304. The outer wall of the top end of the abutting block 303 is in an inclined state, and the direction of the inclined surface of the abutting block 303 is opposite to the rotation direction of the movable block 304. The inner wall of the horizontal rod of the swing arm 2 is formed with a chute for the axial movement of the guiding block 302. The number of the sealing plates 301 is set to two, and the two guiding blocks 302 are symmetrically distributed at the bottom end of the horizontal rod of the swing arm 2.

[0044] In this embodiment: After the dust suppression of the coal blocks is completed through this structure, the swing arm 2 will return to its original position under the action of the vertical rod 1. At this time, the bottom end of the movable block 304 will no longer abut against the top end of the abutting block 303. Then, the movable block 304 will be given a downward pressure under the action of the spring 307, causing the movable block 304 to drive the pulling block 305 to move downward, thereby pulling the two sealing plates 301 closer to each other to protect the atomizing nozzles below the swing arm 2 again.

[0045] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
