[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-3 As shown, a gantry-type dust suppressant spraying device includes a movable frame 1, on which extension rods 12 are symmetrically arranged. A predetermined gap is left between two extension rods 12 to form a clamping part 13. A water discharge roller 14 is provided on the clamping part 13. Multiple placement grooves 20 arranged in a linear array are opened on the water discharge roller 14. A water discharge block 15 is provided in the placement groove 20. A water discharge trough 21 is opened on the water discharge block 15. A first filter plate 22 is provided in the water discharge trough 21. Multiple transverse slots 221 arranged in a circumferential array are opened on the first filter plate 22.

[0024] Specifically, during use, the movable frame 1 is fixed on the fixed track, and then the movable frame 1 is moved. At this time, the dust suppressant enters the water outlet roller 14 in the clamping part 13, then enters the water outlet block 15 in the placement groove 20, then enters the water outlet trough 21 in the water outlet block 15, and finally is discharged through multiple horizontal slots 221 on the first filter plate 22. It should be noted that there are multiple horizontal slots 221, and the discharged dust suppressant will be discharged in a cross shape, which increases the discharge area and pressure.

[0025] In the above scheme, the dust suppressant is sprayed onto the train that is stopped to transport coal by moving the mobile frame 1. The water discharge roller 14 is clamped and fixed by the clamping part 13 formed by the two extension rods 12. The water discharge block 15 is installed by the multiple placement grooves 20 opened on the water discharge roller 14. The dust suppressant is discharged by the water discharge trough 21 on the water discharge block 15. The size of the outlet when the dust suppressant is discharged is increased by the first filter plate 22 in the water discharge trough 21 and the multiple horizontal slots 221 opened on the first filter plate 22, thereby increasing the water pressure.

[0026] As a further embodiment provided by this utility model, according to Figure 1 and Figure 2 As shown, the first filter plate 22 has a circular groove 222.

[0027] Specifically, another portion of the dust suppressant will be discharged into the circular slot 222.

[0028] As a further embodiment provided by this utility model, according to Figure 2 As shown, a second filter plate 23 is provided in the water outlet tank 21, and a plurality of small filter holes 231 arranged in a circular array are provided on the second filter plate 23.

[0029] Specifically, if the water pressure is too low, the second filter plate 23 is installed in the outlet tank 21. Since the diameter of the small filter holes 231 on the second filter plate 23 is smaller than the multiple horizontal slots 221 and circular slots 222 on the first filter plate 22, the water pressure can be further increased.

[0030] As a further embodiment provided by this utility model, according to Figure 2 As shown, a water storage tank 19 is provided on the water discharge roller 14, and the water storage tank 19 is connected to multiple placement tanks 20.

[0031] Furthermore, a water pipe 17 is provided on the water outlet roller 14, and a flow groove 18 is provided on the water pipe 17, which is connected to the water storage tank 19.

[0032] Specifically, the dust suppressant is discharged through the flow channel 18 on the water pipe 17 into the water storage tank 19 opened on the water outlet roller 14.

[0033] As a further embodiment provided by this utility model, according to Figure 1 As shown, a baffle 16 is provided at the bottom of the extension rod 12.

[0034] Specifically, the baffles 16 on both sides prevent the dust suppressant from being sprayed to the outside during spraying.

[0035] As a further embodiment provided by this utility model, according to Figure 2 As shown, a connecting block 11 is provided on the movable frame 1.

[0036] Specifically, the connecting block 11 is designed to facilitate the transport of the mobile frame 1 by a crane.

[0037] Working principle: In use, the moving frame 1 is fixed on the fixed track, and then the moving frame 1 is moved. At this time, the dust suppressant enters the water discharge roller 14 in the clamping part 13, then enters the water discharge block 15 in the placement groove 20, and then enters the water discharge trough 21 in the water discharge block 15. Finally, it is discharged through multiple horizontal slots 221 on the first filter plate 22. It should be noted that there are multiple horizontal slots 221, and the discharged dust suppressant will be discharged in a cross shape, which increases the discharge area and pressure. If the water pressure is too low, the second filter plate 23 is installed in the water discharge trough 21. Since the diameter of the small filter holes 231 on the second filter plate 23 is smaller than the multiple horizontal slots 221 and circular slots 222 on the first filter plate 22, the water pressure can be further increased.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
