[0034] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the technical solution of the present utility model is further described below in conjunction with specific embodiments.

[0035] Combination Figures 1 to 6As shown, this embodiment is a spray device, including a base 1, a rotating adjustment mechanism 7 and a lifting adjustment mechanism. The lifting adjustment mechanism is provided on the base 1, and the lifting adjustment mechanism is connected to a top plate 6 via the rotating adjustment mechanism 7, and a spray assembly is installed on the top plate 6. The lifting adjustment mechanism is used to control the rotating adjustment mechanism 7 and the top plate 6 to reciprocate in the vertical direction, so that the top plate 6 drives the spray assembly to move in the vertical direction, thereby adjusting the spray height of the spray assembly. The rotating adjustment mechanism 7 can drive the top plate 6 to move, so that the top plate 6 rotates around its own axis, and then the top plate 6 drives the spray assembly to rotate, thereby adjusting the spray range of the spray assembly.

[0036] Furthermore, the lifting and adjusting mechanism includes a support plate 2 and a lifting assembly, the rotating adjusting mechanism 7 includes a support seat 3 and a rotating assembly, a support plate 2 is provided on the top of the base 1, the support plate 2 is connected to the support seat 3 via the lifting assembly, the support seat 3 is connected to the top plate 6 via the rotating assembly, and a spray assembly is provided on the top plate 6.

[0037] In some embodiments, the spray assembly includes a column 8 and a spray pipe 9. The top of the top plate 6 is provided with a column 8. The top of the column 8 is connected to a laterally arranged spray pipe 9 via a fixed bracket. The spray pipe 9 has a plurality of nozzles spaced apart along its own axial direction.

[0038] Furthermore, the spray pipe 9 can be set to spray corresponding agents according to different use environments. In this embodiment, the spray pipe 9 is mainly used to spray dust suppressants on construction site dump trucks to suppress dust on the construction site.

[0039] In some embodiments, such as Figure 3 As shown, the lifting assembly includes a first motor 13, a worm 14, a worm wheel 15, a threaded block 16 and a screw 17. The first motor 13 is installed on the top of the support plate 2. The first end of the worm 14 is connected to the output end of the first motor 13. The second end of the worm 14 is fixed to the top of the support plate 2 through a connecting seat. The worm 14 is rotatably connected to the connecting seat, so that the first motor 13 can drive the worm 14 to rotate around its own axis. A cylindrical cavity 18 capable of accommodating the screw 17 is provided inside the base 1. The top of the support plate 2 is rotatably connected to the threaded block 16 through a bearing. The position of the threaded block 16 corresponds to the cylindrical cavity 18. The top of the threaded block 16 is connected to the worm wheel 15, and the worm wheel 15 and the worm 14 are meshed with each other. The first end of the screw 17 is rotatably connected to the bottom of the support seat 3. The second end of the screw 17 sequentially penetrates the worm wheel 15, the threaded block 16 and the support plate 2 and extends into the cylindrical cavity 18. The outer wall of the screw 17 is threadedly connected to the inner wall of the threaded block 16.

[0040] By starting the first motor 13, the first motor 13 drives the worm 14 to rotate, and the transmission is carried out by means of the meshing cooperation between the worm 14 and the worm wheel 15. The worm 14 drives the worm wheel 15 to rotate, and the worm wheel 15 drives the threaded block 16 to rotate. Since the threaded block 16 and the screw rod 17 are threadedly connected, the rotation of the threaded block 16 causes the screw rod 17 to rotate relatively, so that the screw rod 17 drives the support seat 3 and the components thereon to move in the vertical direction. The cylindrical cavity 18 in the base 1 also provides a descending space for the screw rod 17, so as to adjust the spray height of the spray assembly, so as to adapt to different vehicle models for spraying dust suppressants. At the same time, the worm wheel 15 and worm 14 structure has a self-locking function, a large lifting force, a stable center of gravity, a long life, and easy maintenance.

[0041] Furthermore, a buffer assembly is provided between the support seat 3 and the support plate 2, and the buffer assembly includes a support column 4 and a support spring 5. Sliding holes for sliding the support column 4 are opened at the corners of the side of the support plate 2, and the support column 4 is slidably connected in the sliding hole. The end of the support column 4 close to the support seat 3 is connected to the bottom of the support seat 3, and a support spring 5 is sleeved on the outer wall of the support column 4. One end of the support spring 5 is connected to the bottom of the support seat 3, and the other end of the support spring 5 is connected to the top of the support plate 2.

[0042] The support seat 3 is driven to move in the vertical direction by the lifting assembly. At the same time, the support seat 3 drives the support column 4 on the surrounding side to slide in the sliding hole of the support plate 2. The sliding cooperation between the support column 4 and the sliding hole provides auxiliary support and limiting for the support seat 3, making the vertical movement of the support seat 3 more stable. The support spring 5 can buffer and reduce the shock of the movement of the support seat 3, which can greatly reduce the large impact force generated during the lifting and adjustment process.

[0043] In some embodiments, such as Figure 4 As shown, the rotating assembly includes a limit plate 21, a rack 22, a rotating seat 19, a gear 20 and a driving assembly. The top of the support seat 3 is rotatably connected to the rotating seat 19 via a bearing, the top of the rotating seat 19 is connected to the top plate 6, and the outer wall of the rotating seat 19 is sleeved with a gear 20. The top of the support seat 3 is equipped with a limit plate 21, and a slide groove 23 is provided on the side wall of the limit plate 21 facing the gear 20. The back side of the rack 22 is slidably connected to the slide groove 23 via a slider 24, and the rack 22 and the gear 20 are meshed with each other. The limit plate 21 is equipped with a driving assembly, which is connected to the rack 22 and is used to drive the rack 22 to slide in the slide groove 23.

[0044] Furthermore, the driving assembly includes an electric push rod 27, a connecting plate 26 and a connecting rod 25. The electric push rod 27 is installed on the side wall of the limit plate 21 facing away from the rack 22. The driving end of the electric push rod 27, that is, the piston rod end of the electric push rod 27 is connected to the connecting plate 26. The end of the rack 22 close to the connecting plate 26 is connected to the side wall of the connecting plate 26 through the connecting rod 25. The connecting rod 25 and the connecting plate 26 are connected vertically, so that the piston rod of the electric push rod 27 and the connecting rod 25 are parallel to each other.

[0045] By starting the electric push rod 27, the piston rod of the electric push rod 27 drives the connecting plate 26, and the connecting plate 26 drives the rack 22 through the connecting rod 25. Due to the sliding cooperation between the slider 24 and the slide groove 23, the rack 22 moves in the same direction as the connecting plate 26 along the axial direction of the slide groove 23, and limits the movement of the rack 22. At the same time, the meshing cooperation between the rack 22 and the gear 20 causes the rack 22 to drive the gear 20 to rotate, and the gear 20 drives the rotating seat 19 and the top plate 6 to rotate, so that the spray pipe 9 on the top plate 6 rotates with the axis of the column 8 as the center of the circle, so as to adjust the spray angle of the spray pipe 9, so as to further adjust the spray path and spray range of the spray pipe 9.

[0046] In some embodiments, such as Figure 5 and Figure 6 As shown, a protective tube 10 is provided on the outer sleeve of the spray pipe 9, and a chamber for accommodating the spray pipe 9 is provided inside the protective tube 10. The outer wall of the spray pipe 9 and the inner wall of the protective tube 10 are rotatably connected via bearings. The protective tube 10 is provided with through holes 28 corresponding to the nozzles at intervals along its own axial direction. A transmission assembly connected to the protective tube 10 is installed on the top plate 6, and the transmission assembly is used to drive the protective tube 10 to rotate around its own axis.

[0047] Furthermore, the transmission assembly includes a second motor 11 and a pulley assembly 12 . The second motor 11 is installed on the top of the top plate 6 , and the output end of the second motor 11 is rotatably connected to the protective tube 10 via the pulley assembly 12 .

[0048] When it is necessary to work, the second motor 11 is started, the second motor 11 drives the pulley assembly 12, and the pulley assembly 12 drives the protective cylinder 10 to rotate until the through hole 28 on the protective cylinder 10 corresponds to the nozzle position on the spray pipe 9. At this time, the dust suppressant sprayed from the nozzle on the spray pipe 9 is sprayed outward through the through hole 28 of the protective cylinder 10; when it is not necessary to work, the second motor 11 is started, the second motor 11 drives the pulley assembly 12, and the pulley assembly 12 drives the protective cylinder 10 to rotate until the through hole 28 on the protective cylinder 10 is misaligned with the nozzle on the spray pipe 9, thereby avoiding the nozzle from being directly exposed to the outside, and can prevent external dust and rainwater from contacting the nozzle to a certain extent, which plays a good protective role on the nozzle, thereby effectively extending the service life of the nozzle.

[0049] Furthermore, the diameter of the end of the inner chamber of the protection tube 10 close to the top plate 6 is smaller, and the diameter of the end of the inner chamber of the protection tube 10 away from the top plate 6 is larger. A plurality of drainage slits 29 are provided at intervals along the circumference of the end of the protection tube 10 away from the top plate 6 .

[0050] By setting the diameter size of both ends of the accommodating chamber, when the spray pipe 9 stops spraying, at the moment of stopping, part of the liquid in the spray pipe 9 will flow out through the nozzle into the chamber. Since the inner wall of the chamber is inclined, this part of the liquid will flow along the inclined surface to the drainage gap 29 and further be discharged through the drainage gap 29, thereby reducing the situation where the nozzle is in a humid environment for a long time.

[0051] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
