For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] like Figure 1 As shown, the utility model provides a spray dust reduction device which increases the spray range and improves the dust reduction effect.

[0029] The spray dust suppression device comprises a base 1, an adjusting device, a water supply device and a spray head 9, wherein the adjusting device is arranged on the base 1, the spray head 9 is installed on the adjusting device, the adjusting device is used to adjust the spray range of the spray head 9, the water supply device is provided with a water pipe 11 connected with the spray head 9, the spray direction of the spray head 9 is at least one of horizontal, obliquely upward and obliquely downward, the adjusting device comprises a telescopic device and a rotating device, the telescopic device is fixedly arranged on the base 1, the telescopic device comprises a rotating motor A3, a screw 5, a lifting pipe 6 and a fixing frame 4, the rotating motor A3 and the fixing frame 4 are installed on the base 1, one end of the screw 5 is connected to the output shaft of the rotating motor A3, the lifting pipe 6 is vertically arranged, penetrated in the fixing frame 4, and is screwed with the screw 5 The lifting tube 6 is connected by a thread pattern. A first matching portion is provided on the outer peripheral side of the lifting tube 6, and a second matching portion is provided on the fixing frame 4. The first matching portion matches with the second matching portion to control the lifting tube 6 to move linearly in the vertical direction. The rotating device includes a supporting frame 7 and a rotating motor B8. The bottom of the supporting frame 7 is fixedly connected to the lifting tube 6. The spray head 9 and the rotating motor B8 are installed on the supporting frame 7. The water pipe 11 is rotatably connected to the spray head 9. The water pipe 11 is a fixed component, and the spray head 9 is a rotating component. The rotating axis of the spray head 9 is a vertical axis. The spray head 9 is drivingly connected to the output shaft of the rotating motor B8 to control the rotation of the spray head 9 around the vertical axis. The controller 17 is also included. The rotating motor A3 and the rotating motor B8 are electrically connected to the controller 17 respectively.

[0030] In the present solution, the first matching portion is located on the outer peripheral side of the lifting tube 6. The first matching portion can be set on the entire vertical section of the lifting tube 6, or on a part of the vertical section. The second matching portion is located on the top of the fixing frame 4, specifically a non-circular special-shaped hole. The shape of the first matching portion corresponds to the special-shaped hole. The special-shaped hole is matched with the clearance of the outer peripheral side of the lifting tube 6 to stop the lifting tube 6 from rotating.

[0031] In this solution, in order to ensure that the water pipe 11 does not get entangled or twisted during the rotation of the spray head 9, the water pipe 11 only needs to supply water to the spray head 9, and a fixed connection is not used. A bearing can be set at the end of the water pipe 11 to rotate with the spray head 9. The connection position of the water pipe 11 and the spray head 9 is located on the rotation axis of the spray head 9, which ensures that the water pipe 11 remains fixed relative to the support frame 7, so that the water pipe 11 does not rotate, and the water pipe 11 is prevented from interfering with the rotation of the spray head 9. The spray direction of the spray head 9 is at least one of horizontal, oblique upward and oblique downward, which ensures that the spray head 9 has a large spray range. The spray direction is the spray direction of the spray water. Since the dust is mainly concentrated in a relatively high area, the spray direction of the spray head 9 in this embodiment is preferably obliquely upward for spraying, which can save water and the mixture of water and dust falling from a high place can also take away the dust from a low place. In order to avoid water leakage of the device, a sealing gasket for sealing is also provided between the water pipe 11 and the spray head 9.

[0032] It should be noted that the present solution controls the forward or reverse rotation of the rotating motor A3 through the controller 17. The rotating motor A3 is a three-phase asynchronous motor known on the market. The rotating motor A3 can realize the forward and reverse rotation of the rotating motor A3 by matching a three-phase power supply with an adjustable phase sequence, while the rotating motor B8 is an ordinary motor and can be kept in forward rotation. The controller 17 controls the forward, reverse and stop rotation of the rotating motor A3, so that the spray head 9 can be extended and retracted up and down within the set range, or stay at a specified height. The controller 17 controls the start or stop of the rotating motor B8, so that the spray head 9 can rotate and spray within a range of 360° or spray in a specified direction. The water supply device can be an external water supply device, or it can be a water storage device installed inside the device to supply water. In addition, the spray head 9 is connected to the output shaft of the rotating motor B8 by driving. The spray head 9 can be directly fixedly connected to the output shaft of the rotating motor B8, or a transmission element can be set between the spray head 9 and the output shaft of the rotating motor B8 to connect. For example, a gear is set on the output shaft, and a gear is also set at the lower end of the spray head 9. The two gears are meshed to achieve a transmission effect.

[0033] In some embodiments, a branch pipe 10 extends downward from the upper end of the support frame 7 in the vertical direction, and the branch pipe 10 is rotatably connected to the upper end of the spray head 9. The lower end of the spray head 9 is installed on the output shaft of the rotating motor B8. The water pipe 11 is fixed on the support frame 7. A through hole connecting the branch pipe 10 is provided on the support frame 7. The water pipe 11 is inserted in the through hole and the branch pipe 10. A sealing structure is provided between the water pipe 11 and the through hole, and a sealing structure is provided between the branch pipe 10 and the spray head 9. There is no restriction on the shape of the support frame 7. It can be set as a C-shaped bracket or a circular bracket. As long as it can provide an installation and support function for the spray head 9 and does not interfere with the rotation of the spray head 9, other shapes are acceptable. The vertically extending branch pipe 10 is rotatably connected to the spray head 9, and a bearing and the spray head 9 can be installed on the branch pipe 10, or a convex ball head is installed on the branch pipe 10, and a groove is provided on the corresponding spray head 9, and the convex ball head and the groove are rotatably matched. On the one hand, the provision of the branch pipe 10 can avoid friction between the water pipe 11 and the rotating sprinkler head 9, thereby preventing damage to the water pipe 11; on the other hand, it can also provide a stable support for the top of the sprinkler head 9, thereby preventing the sprinkler head 9 from rotating and deviating, thereby enhancing the stability of the overall device. A sealing structure is provided between the water pipe 11 and the through hole, and a sealing structure is provided between the branch pipe 10 and the sprinkler head 9. The sealing structure may be a sealing gasket, or a stuffing box may be provided between the water pipe 11 and the through hole, and between the branch pipe 10 and the sprinkler head 9, wherein a moist stuffing box is filled. This type of sealing can enhance the sealing ability and will not generate greater friction for rotation.

[0034] In some embodiments, the spray head 9 is fixedly connected to the output shaft of the rotating motor B8. The spray head 9 and the output shaft of the rotating motor B8 can be fixed by welding, which directly drives the spray head 9 to rotate along the vertical axis, reduces manufacturing costs, and has higher transmission efficiency.

[0035] In some embodiments, the cross section of the first matching portion is a square, the second matching portion is a square hole, and the first matching portion and the second matching portion are clearance matched. In addition to setting the cross section of the first matching portion to a square, it can also be set to other special shapes, and the second matching portion is also set accordingly, such as a triangle, a pentagon, a hexagon or other irregular shapes, as long as the purpose of stopping rotation can be achieved. A flange for stopping rotation can also be welded on the fixing frame 4, and the center hole of the flange is the above-mentioned special-shaped hole, and the first matching portion is also set to a special-shaped cross section accordingly, which can also achieve the purpose of stopping rotation.

[0036] In some embodiments, the water supply device includes a water pump 12, a water tank 16 is provided on the base 1, and the water pipe 11 includes a water inlet pipe and a water outlet pipe, one end of the water inlet pipe is connected to the water tank 16, and the other end is connected to the water inlet end of the water pump 12, one end of the water outlet pipe is connected to the water outlet end of the water pump 12, and the other end is connected to the sprinkler head 9. The water inside the water tank 16 is pumped out by the water pump 12, and the water in the water tank 16 is transported to the sprinkler head 9, which further optimizes the use conditions of the spray dust suppression device. When there is no external water supply equipment, the water stored in the water tank 16 can also supply water to the sprinkler head 9, expanding the application scenario of the device. The water pump 12 here can also be a submersible pump, which is directly placed in the water tank 16 for pumping water.

[0037] In some embodiments, the base 1 is also provided with side panels around it, and the top of the side panels is provided with a cover plate, and the base 1, the side panels and the cover plate form a box. The side panels and the cover plate are provided on the base 1 to protect the electrical components on the base 1, to prevent spray water and dust from splashing onto the electrical components and causing a short circuit of the device, and to provide a normal working environment for the internal components. The side panels and the cover plate can also provide an installation condition for installing other parts.

[0038] In some embodiments, the side panel is also provided with a solar panel 15 to provide an additional power source for the device, which not only saves energy but also can cope with the spraying area where power supply is difficult. The solar panel 15 can absorb solar energy and convert it into electrical energy for storage or use, which is a conventional technology and will not be described in detail here. By utilizing natural energy, energy loss can be saved, which is in line with the concept of environmental protection.

[0039] In some embodiments, the cover plate is further provided with a dust concentration detector 13, which is used to assist in detecting the dust concentration in the air, so as to spray and reduce dust in time to avoid excessive diffusion of dust.

[0040] In some embodiments, the cover plate is further provided with a spray device display 14. The spray device display 14 is used to display the storage power, temperature and dust concentration of the device, etc., so that the device tends to be intelligent and digital.

[0041] In some embodiments, a universal wheel 2 with a brake structure is fixed to the bottom surface of the base 1. This allows the entire device to be moved within the work site, saving energy and reducing labor intensity compared to the traditional fixed type that requires a carrier to move. The universal wheel 2 with a brake structure improves the controllability and safety of the device. When working on a slope or uneven site, the universal wheel 2 with a brake structure can prevent the safety risks of sudden acceleration of the device. In addition, the universal wheel 2 with a brake structure can allow the user to accurately control the position of the device and keep it fixed at the designated work position.
