For example, their rotation angle may be limited and cannot cover the required area; or the control method is not flexible enough, making it difficult to make precise spraying adjustments according to actual needs. These problems limit the application effect of rotary sprinklers in diversified spraying needs.

DETAILED DESCRIPTION

[0028] The present invention is described below with specific embodiments, but they are not intended to be limiting of the invention.

[0029] Embodiment 1 like Figure 1-Figure 8 As shown, in this embodiment, a spray dust reduction device is provided, which includes a support column 1, a top plate 2 and a spray unit.

[0030] The top plate 2 is fixed to the upper end of the support 1. The top plate 2 is a horizontally arranged plate body. The top plate 2 is arranged horizontally, and its peripheral design realizes 360-degree full coverage, which means that the spray device can be installed along the entire periphery of the plate body. The spray coverage can be effectively expanded without rotating the plate body.

[0031] The spray unit is arranged on the periphery of the top plate 2 along the circumferential direction of the annular surface of the top plate 2. The spray unit can be conveniently installed and fixed on the outer annular surface of the top plate 2. Such a layout simplifies the installation process and ensures the stability of the fixation. Due to this design, the spray device can set the spray area in multiple directions around the top plate 2, thereby greatly improving the efficiency and coverage of the spray. Such a design not only simplifies the operation process, but also significantly enhances the flexibility and practicality of the spray system.

[0032] Among them, the outer periphery of the top plate 2 is fixed with a support ring 3 through a connecting rod 6, and a connecting rod 6 is fixed on the inner side of each support ring 3. The connecting rod 6 is fixed on the inner ring surface of the top plate 2. The support ring 3 is provided with multiple openings, and a water pipe joint 4 is fixedly installed at each opening. The design of the opening is mainly for installing the spray unit. The water pipe joint 4 is a component that connects the spray unit with the water source, and it is responsible for providing the spray unit with the required spraying liquid. The tight connection between the water pipe joint 4 and the nozzle 5 can ensure the realization of the spraying effect. In addition, a plurality of such openings are provided on the top plate 2 to provide installation positions for a plurality of spraying units, so as to meet a wider and more flexible spraying demand. A plurality of water pipe joints 4 are connected to the main water supply pipe, and liquid is provided to the main water supply pipe through the main water supply pipe. The connection between the water pipe joint 4 and the main water supply pipe can be connected through a multi-way joint. The multi-way joint is a prior art and is not an innovation of the present invention, so the present invention will not be specifically explained. A plurality of spraying units are installed at the corresponding water pipe joints 4. The spraying unit includes at least one nozzle 5, and the spraying angle of the nozzle 5 can be adjusted up and down. A driving assembly for driving the spraying head to rotate is installed in the top plate 2. Under the precise control of the driving assembly, the nozzle 5 can flexibly adjust its orientation angle to achieve up and down swinging. This adjustment mechanism enables the coverage area of ​​the spraying to be changed according to actual needs. Specifically, by adjusting the angle of the nozzle 5, the range of the spraying can be increased or decreased to meet the spraying needs in different scenarios.

[0033] Embodiment 2 like Figure 1-Figure 8 As shown, based on the first embodiment, this embodiment provides a structure of a spraying unit, which is as follows: The spraying unit also includes a casing 7, a nozzle 5 is fixed on the casing 7, the casing 7 is sleeved on the water pipe joint 4, a water inlet 8 is provided on the water pipe joint 4, an inner hole is provided inside the casing 7, the inner hole is communicated with the nozzle 5, the inner hole is adapted to the water inlet 8, and the driving assembly is responsible for driving the casing 7 to rotate around the water pipe joint 4. During the rotation of the casing 7, there are two states of overlap and non-overlap between the water inlet 8 thereon and the inner hole of the water pipe joint 4. When the water inlet 8 and the inner hole are in a completely overlapped and partially overlapped position, the liquid will smoothly flow from the water inlet 8 into the inner hole, and then be injected into the nozzle 5, and finally the liquid will be sprayed through the nozzle 5. In particular, when the casing 7 is rotated to certain specific angles, the water inlet 8 will accurately overlap with the inner hole to ensure the smooth flow of the liquid. However, when the water inlet 8 does not coincide with the inner hole, that is, the inner wall of the casing 7 blocks the water inlet 8, the water inlet 8 cannot provide liquid to the inner hole, and accordingly, the nozzle 5 cannot spray the liquid.

[0034] The inner hole is opened in the water pipe joint 4 in an arc shape along the axial direction of the rotation of the sleeve 7. The arc shape design can widen the angle range of liquid supply to the nozzle 5, which means that even when the nozzle 5 rotates to a large extent, it can ensure continuous liquid supply to it. This design effectively ensures that the nozzle 5 can have a wider coverage area when spraying liquid, thereby improving the efficiency and effect of spraying.

[0035] The driving assembly includes a first gear 9 rotatably mounted inside the top plate 2, a second gear 10 is fixed outside the casing 7, and a motor for driving the corresponding first gear 9 to rotate is fixed inside the top plate 2. When the motor is started, it drives the first gear 9 to rotate. Due to the meshing relationship between the first gear 9 and the second gear 10, the rotation of the first gear 9 drives the second gear 10 and the casing 7 fixed thereto to rotate together. The automatic rotation of the casing 7 is achieved through the drive of the motor. The rotation of the casing 7 in turn drives the rotation of the nozzle 5 thereon, so that the nozzle 5 can change the spraying angle, thereby increasing and decreasing the spraying coverage.

[0036] An end hole is provided at one end surface of the casing 7, and the end of the water pipe joint 4 is inserted into the end hole. A support shaft 11 is fixed to the end of the casing 7 away from the end hole, and the bearing shaft is rotatably mounted inside the support ring 3. Through the design of the end hole and the support shaft 11, a stable connection and support between the water pipe joint 4 and the casing 7 is achieved. This connection method not only ensures the smooth flow of the liquid, but also enables the casing 7 to rotate stably under the drive of the driving component. At the same time, the design of the support shaft 11 and the support ring 3 also improves the structural stability of the entire spray dust reduction device.

[0037] Embodiment 3 like Figure 3-Figure 8As shown, based on the first and second embodiments, this embodiment provides two nozzle 5 structures, which are as follows: There are two nozzles 5 on each casing 7. The casing 7 is provided with inner holes adapted to the nozzles 5. The circumferential angle between the two inner holes is greater than the curvature of the water inlet 8. The two nozzles 5 configured on each casing 7 are intended to achieve two different spraying modes: one is a diffuse spraying mode, which is intended to expand the spraying area; the other is a remote spraying mode, which is used to achieve spraying at a longer distance. The two nozzles 5 are respectively connected to two adapted inner holes provided inside the casing 7, and the circumferential angles of the two inner holes are designed to be relatively large. This design cleverly utilizes the characteristics of the casing 7 when it rotates: when the casing 7 rotates to a preset angle, its inner wall can accurately cover the water inlet 8, thereby effectively blocking the flow of the liquid and realizing the closing function of the nozzle 5. Such a layout not only improves the diversity and flexibility of spraying, but also ensures that the nozzle 5 can be quickly and reliably closed when spraying is not required.

[0038] The two nozzles 5 on the same housing 7 include a first nozzle 51 and a second nozzle 52 respectively. The spray distance of the first nozzle 51 is greater than the spray distance of the second nozzle 52. The two spray distances can be switched arbitrarily as needed.

[0039] The first nozzle 51 includes a plurality of first conical holes 53 connected to the inner hole, the tips of the plurality of first conical holes 53 are directed toward the outside of the nozzle, the plurality of first conical holes 53 include a straight hole arranged in the middle and a plurality of inclined holes circumferentially arranged around the straight hole, the spraying angles of the plurality of inclined holes are all directed toward the straight hole, and there is an intersection between the water columns sprayed from the plurality of inclined holes and the straight hole. The water columns will generate force on each other after crossing, so that the plurality of water columns are scattered at a position far away from the first nozzle 51, that is, a spraying effect is generated after scattering in a distance, thereby achieving a spraying effect at a longer distance.

[0040] The second nozzle 52 includes a plurality of second conical holes 54 connected to the inner hole, the tips of the plurality of second conical holes 54 are directed toward the outside of the nozzle, and a water retaining bar is provided on the outside of the end of the second conical holes 54. When the water column encounters the water retaining bar, scattering will be directly generated, that is, a scattering effect will be generated around the second nozzle 52.

[0041] Working principle: The main water supply pipe is connected to multiple water pipe joints 4 through a multi-way joint to provide the required spraying liquid for the spraying unit. When the motor is started, it drives the first gear 9 to rotate. Due to the meshing relationship between the first gear 9 and the second gear 10, the rotation of the first gear 9 drives the second gear 10 and the housing 7 fixed thereto to rotate together.

[0042] The housing 7 rotates under the drive of the driving assembly, and there are two states of overlap and non-overlap between the water inlet 8 and the inner hole of the water pipe connector 4. When the water inlet 8 overlaps with the inner hole, the liquid will flow from the water inlet 8 into the inner hole, and then be injected into the nozzle 5 and sprayed out from the nozzle 5. By adjusting the angle and spraying pattern of the nozzle 5, the coverage area and spraying effect of the spraying can be changed.

[0043] Two nozzles 5 are arranged on each housing 7, respectively realizing a diffuse spraying mode and a remote spraying mode. When the housing 7 is rotated to a preset angle, its inner wall can accurately cover the water inlet 8, thereby effectively blocking the flow of liquid and realizing the closing function of the nozzle 5. By switching different nozzles 5 for spraying, different spraying needs can be met.

[0044] The water columns ejected from the first nozzle 51 through the inclined holes of the plurality of first conical holes 53 and the straight holes generate a cross force, which produces a scattering effect at a position far from the nozzle, thereby achieving spraying at a longer distance. The second nozzle 52 directly produces a scattering effect through the water retaining strip, which produces a spraying effect around the second nozzle 52. This design not only improves the uniformity and coverage of the spraying, but also enhances the dust reduction effect of the spraying.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
