[0026] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0028] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0029] See also Figures 1 to 8As shown, the utility model provides a foldable multi-section dust suppression spray rod 100, including three sections of brackets connected end to end, namely the first bracket 2, the second bracket 3 and the third bracket 4. In this embodiment, the bracket is a rectangular parallelepiped with a hollow interior. A water pipe is provided in each bracket, and each water pipe is connected to a number of nozzles 9. The nozzle of the nozzle is adjustable, and spraying or direct water spraying can be selected according to needs; the nozzle is a prior art, and the prior art can be used, which will not be repeated here. In this embodiment, the nozzles on each bracket are arranged at equal intervals.

[0030] The foldable multi-stage dust suppression spray rod 100 also includes an angle adjustment joint 5 connecting adjacent brackets and a connecting hose connecting the water pipes in the adjacent brackets. The angle adjustment joint 5 includes a U-shaped seat 51, a connecting block 52 rotatably connected to the U-shaped seat 51, a servo reduction motor 53 and an electric push rod 54 respectively connected to the two side walls of the U-shaped seat 51. The connecting block 52 is movably connected to the inside of the U-shaped seat 51 through a rotating shaft 531. The servo reduction motor 53 is used to drive the angle rotation. The output shaft of the servo reduction motor 53 passes through the U-shaped seat 51 and is connected to the connecting block 52. The output end of the electric push rod 54 is connected to a pin 55 through a coupling. The connecting block 52 is arranged between the two side walls of the U-shaped seat 51. Eight jacks 521 are arranged on one side of the connecting block 52 close to the electric push rod 54; the eight jacks 521 are distributed in a circular array with the central axis of the connecting block 52 as the center. It should be understood that the number of jacks can be set to other values ​​as needed, and is not specifically limited to this.

[0031] A cavity 511 for the plug 55 to pass through is formed on the side wall of the U-shaped seat 51 . The plug 55 passes through the cavity 511 and is selectively inserted into one of the eight insertion holes.

[0032] In this way, after the angle adjustment joint 5 is adjusted according to actual needs, the electric push rod 54 can be used to push the pin 55 into the corresponding socket 521 on the connecting block 52, so that the angle between the U-shaped seat 51 and the connecting block 52 will no longer change. The eight sockets 521 make the fixed angle interval 45° each time, so that different angles can be maintained when multiple sections of the bracket are deployed, and the adaptability is wider.

[0033] Specifically, the water inlet end of the first water pipe 21 in the first bracket 2 is connected to the external hose 1, and the external hose 1 can be used to connect the external dust suppressant pipeline. The head end of the first bracket 2 is provided with a circular hole 22 for the external hose 1 to pass through. The circular hole 22 is provided on the side wall away from the nozzle to avoid interference between the external hose 1 and the first bracket 2.

[0034] A first angle adjustment joint is provided at the connection between the first bracket 2 and the second bracket 3, a U-shaped seat 61 of the first angle adjustment joint is connected to the tail end of the first bracket 2, and a connection block 62 of the first angle adjustment joint is connected to the head end of the second bracket 3. Similarly, a second angle adjustment joint is provided at the connection between the second bracket 3 and the third bracket 4, a U-shaped seat of the second angle adjustment joint is connected to the tail end of the second bracket, and a connection block of the second angle adjustment joint is connected to the head end of the third bracket.

[0035] The first water pipe 21 is connected to the second water pipe 31 in the second bracket 3 through the first connecting hose 81. The tail end of the first bracket 2 is provided with a first opening for the first connecting hose 81 to pass through, and correspondingly, the head end of the second bracket 3 is provided with a second opening for the first connecting hose 81 to pass through.

[0036] Similarly, the second water pipe 31 is connected to the third water pipe 41 in the third bracket 4 via a second connecting hose 82 .

[0037] The tail end of the second bracket 3 is provided with a third opening 311 for the second connecting hose 82 to pass through, and the head end of the third bracket is provided with a fourth opening 411 for the second connecting hose 82 to pass through.

[0038] In this way, when the multi-section bracket is unfolded or folded and recovered, the connecting hose used to connect adjacent water pipes passes through the opening to avoid interference between the connecting hose and the first bracket 2, the second bracket 3 and the third bracket 4, and during this period, the connecting hose will undergo adaptive deformation as the multi-section bracket is unfolded and recovered.

[0039] It should be noted that those skilled in the art should understand that in practical applications, the number of brackets can be increased as needed, and is not limited to this.

[0040] The working process of the foldable multi-stage dust suppression spray boom 100 of the utility model is as follows:

[0041] When it is necessary to spray dust suppressant, the first bracket 2, the second bracket 3 and the third bracket 4 can be expanded or retracted through the angle adjustment joint 5. When the angle adjustment joint 5 is in operation, the connecting block 52 is mainly driven to rotate by the output shaft of the servo reduction motor 53. During this period, the brackets (the second bracket 3, the third bracket 4) connected to the connecting block 52 will rotate synchronously. After the angle of the connecting block 52 is determined, the pin 55 can be pushed and inserted into the socket 521 through the electric push rod 54. At this time, the angle between the U-shaped seat 51 and the connecting block 52 is fixed by the pin 521 and will no longer change at will. Subsequently, the dust suppressant can be sprayed out through the nozzle 9 for dust suppression. After use, the above steps can be reversed to recycle and fold the multi-segment bracket. After recycling and folding, the electric push rod 54 in each angle adjustment joint 5 needs to push the pin 55 into the corresponding socket 521 again to fix the U-shaped seat 51 and the connecting block 52, so that the multi-segment bracket will not be expanded at will.

[0042] In summary, the foldable multi-section dust suppression spray rod 100 provided by the utility model is designed as a multi-section bracket connected end to end, and each bracket of the multi-section bracket is connected by an angle adjustment joint; when the multi-section bracket needs to be folded / unfolded, the servo reduction motor drives the connection block to rotate to the target angle, and then the electric push rod is used to insert the pin into the corresponding socket. At this time, the angle between the U-shaped seat and the connection block is fixed by the pin and will no longer change at will. The multi-section bracket of the utility model only occupies a small space in the folded state, and can change the angle from the vertical state to the lying state, and can achieve multi-angle stay. At the same time, the multi-section bracket has a wider coverage area after being unfolded, thereby achieving dust suppression operations over a larger area.

[0043] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
