[0040] The rotating assembly includes a second support plate 17 arranged on the bottom plate 1, one side of the second support plate 17 is connected to the rotating member 8 through a long rotating shaft 20, a second turntable 9 is arranged on the long rotating shaft 20, and a belt 14 is wound around the second turntable 9 and the first turntable 7.

[0041] As attached Figure 5 As shown, a slot 19 is provided on the side of the vertical rod 13, an extension rod is provided on the side of the linkage member 16 close to the vertical rod 13, the extension rod passes through the slot 19, a fastener is provided on the extension rod, and an arched slot is provided on the side of the linkage member 16.

[0042] As attached Figure 4 and attached Figure 6As shown, a rotating disk 111 is provided at the bottom end of the rotating rod 11, and the rotating disk 111 is embedded in a notch near the upper end of the vertical rod 13. The rotating rod 11 and the vertical rod 13 rotate relative to each other, and a material passage trough 18 is provided in both the rotating rod 11 and the vertical rod 13.

[0043] As attached Figure 1 -Attached Figure 3 As shown, the rotating fitting part 12 is cylindrical, and a through groove 124 is provided in the rotating fitting part 12. A limit block 125 is symmetrically arranged on the side of the through groove 124, and the limit block 125 is embedded in the groove rail on the side of the rotating rod 11. Limit plates 121 are provided at the upper and lower ends of the rotating fitting part 12. Limit grooves 122 are symmetrically provided on the limit plate 121.

The two rotating grooves 123 are symmetrically arranged.

[0044] As attached Figure 1 -Attached Figure 2 and attached Figure 4 As shown, the rotating member 8 is divided into a cylindrical rotating rod 81 and a strip column rod 82. The cylindrical rotating rod 81 and the strip column rod 82 are arranged vertically and cross each other. Arc plates are arranged at both ends of the strip rotating rod 82. The rotating member 8 and the limiting groove 122 are located in the same horizontal plane. When the rotating member 8 is in the rotating state, the cylindrical column rod 81 is embedded in the rotating groove 123, and the arc plate is embedded in the limiting groove 122.

[0045] As can be seen from the above, after the staff pushes the equipment to the required position, the sprayer 4 is started, so that the liquid is pumped from the storage barrel 3 into the material trough 18, and the motor 15 is started at the same time, and then the motor 15 drives the second short shaft 22 to rotate, and then drives the first short shaft 21 to achieve circular rotation. Because the first short shaft 21 is embedded in the linkage member 16, the vertical rod 13 drives the sub-disc 10 to move up and down. When the motor 15 rotates, as the first turntable 7 rotates, the second turntable 9 is driven to rotate under the drive of the belt 14, so that the rotating member 8 rotates. During the rotation process, the end of the cylindrical rotating rod 81 is embedded in the rotating groove 123, so that the rotating matching member 12 is rotated, and then the rotating rod 11 and the sub-disc 10 are driven to rotate. Since the rotating groove 123 is cross-symmetrically arranged When the rotating member 8 is continuously rotating, the rotating matching member 12 rotates back and forth, the sprayer 4 extracts the liquid in the storage barrel 3, and then pumps the liquid to the material trough 18 through the hose 5, and then the material trough 18 pumps the liquid to the oblique nozzle 101 and the vertical nozzle 102, thereby spraying it out, driving the sub-disc 10 to move up and down, and the water can be sprayed to different heights in the space. The second turntable 9 is driven by the belt 14 to rotate synchronously, thereby driving the rotating member 8 to rotate, and the end of the cylindrical rotating rod 81 rotates along the rotating groove 123, thereby driving the rotating matching member 12 and the sub-disc 10 to rotate, so that the water can move up and down and can rotate at the same time. The same power of the above structure realizes the up and down movement and rotation of the sub-disc 10, and the design is scientific and reasonable.

[0046] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that Figure 1 -Attached Figure 5 and attached Figure 7 As shown, the first short axis 21 and the second short axis 22 are arranged in parallel, the telescopic rod 23 includes a moving rod 231 vertically arranged on the side of the last 21 of the first section, a sleeve rod 232 is provided on the outer surface of the moving rod 231, an inner cavity 2321 is opened in the sleeve rod 232, and a plurality of groups of limiting holes 2322 are symmetrically opened on the side of the sleeve rod 232, a telescopic hole 2311 is opened on the side of the moving rod 231 near the bottom end, a telescopic block 233 is slidably arranged in the telescopic hole 2311, the bottom of the telescopic hole 2311 is connected to the second spring 2312, the other end of the second spring 2312 is connected to the bottom of the telescopic block 233, the telescopic block 233 is embedded in the limiting hole 2322, the sleeve rod 232 is vertically arranged on one side of the second short axis 22, and the first short axis 21, the telescopic rod 23 and the second short axis 22 form a "Z" shape.

[0047] As can be seen from the above, when it is necessary to adjust the height of the up and down movement, loosen the fasteners on the side of the vertical rod 13, and then adjust the distance between the linkage 16 and the base plate 1. At the same time, adjust the length of the telescopic rod 23. Specifically, press the telescopic block 233 to squeeze the second spring 2312, and embed the telescopic block 233 into different limit holes 2322 to adjust the length of the telescopic rod 23. Only after adjusting different lengths can the height of the up and down movement be achieved. The device can be adjusted according to the actual specific situation, thereby further expanding the scope of application of the device and being able to adapt to different scenes.

[0048] Embodiment 3: This embodiment is basically the same as the previous embodiment, except that Figure 8 and attached Fig. 9 As shown, the side of the sub-plate 10 is evenly provided with oblique nozzles 101, the upper end of the sub-plate 10 is evenly provided with vertical nozzles 102, the sub-plate 10 is provided with a sub-slot 103, the sub-slot 103 is connected with the material trough 18, the sub-slot 103 is respectively connected with a plurality of oblique nozzles 101 and a plurality of vertical nozzles 103, a swing plate 1021 is rotatably arranged in the vertical nozzle 103, a first spring 1022 is arranged on one side of the swing plate 1021, and the other end of the first spring 1022 is connected to the inner wall of the vertical nozzle 103.

[0049] As can be seen from the above, when the device is performing a water spraying operation, liquid is drawn out from the storage barrel 3, and then passes through the branch groove 103. When the liquid is sprayed out, it will impact the swing plate 1021, thereby realizing the rotation of the swing plate 1021. Under the squeezing of the first spring 1022, the swing plate 1021 is realized to swing, so that the liquid sprays out in an "S" shape, making the coverage range of the device spraying wider.
