Description

Technical Field

[0001] This utility model relates to the technical field of dust suppression devices, specifically a dust suppression spray device. Background Technology

[0002] A dust suppression spray device is a device that reduces the amount of dust in the air by spraying. On construction sites, construction activities such as earthwork excavation, loading and unloading of building materials and transportation generate a lot of dust. The dust suppression spray device can effectively suppress the spread of dust by setting up nozzles around the construction site and spraying at regular intervals.

[0003] The utility model patent application with publication number "CN222342378U" discloses a dust suppression spray device, which mainly consists of a mobile box, a fog cannon, a water pump assembly, a transmission pipe, a flow valve, a filter box, and a filtration mechanism. This technical solution solves the problems that most existing dust suppression spray devices do not have a filtration structure. Impurities, particulate matter, or microorganisms in the water tend to accumulate inside the nozzle after long-term use, causing the nozzle orifices to become smaller or even completely blocked, affecting subsequent dust suppression work. Furthermore, most dust suppression devices can only spray dust at a specific angle, which is not convenient for effectively covering the area that needs dust suppression, making it impossible to suppress some dust and achieve the expected dust suppression effect.

[0004] The dust suppression spray device disclosed in the aforementioned document has the following defects: The existing dust suppression spray device, the fog cannon, is generally composed of a wind duct and an atomizing nozzle. When in use, the wind force generated inside the wind duct sprays water particles that have passed through the atomizing nozzle to a long distance to achieve the purpose of dust suppression. However, in the existing technology, the wind duct and the atomizing nozzle are generally fixedly connected by bolts. When it is necessary to replace the atomizing nozzle, it is necessary to remove the multiple bolts connecting the wind duct and the atomizing nozzle, which is quite cumbersome. Utility Model Content

[0005] The purpose of this utility model is to provide a dust suppression spray device that solves the problem of inconvenience in separating the air duct and atomizing nozzle of the fog cannon in the existing dust suppression spray device.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a dust suppression spray device, comprising a base plate, with casters mounted on the lower surface of the base plate, and a cabinet mounted on the upper surface of the base plate. A cabinet door is hinged to one end of the cabinet. An extraction pump and a water tank are installed inside the cabinet. A ventilation duct is mounted on the upper surface of the cabinet, with an atomizing nozzle at one end. A first connecting plate is located at one end of the atomizing nozzle. A second connecting plate is located on the outer surface of the ventilation duct, with mounting holes on its outer surface. A connecting block is located on the outer surface of the first connecting plate, and the connecting block is fitted onto the first connecting plate. Inside the mounting hole, the connecting block has a cavity. Inside the cavity, a first limiting block is slidably connected. There are two first limiting blocks, symmetrically distributed. One end of each first limiting block passes through the connecting block and extends outward. A first spring is installed between the two first limiting blocks. The inlet end of the pump is equipped with a pumping pipe. One end of the pumping pipe extends into the water storage tank. The outlet end of the pump is equipped with a drain pipe. One end of the drain pipe passes through the cabinet and is equipped with a connecting assembly. The other end of the connecting assembly is equipped with an atomizing nozzle.

[0008] Furthermore, a sliding groove is provided on the outer surface of the connecting block, one end of which extends into the interior of the cavity, and a lever is installed at one end of each of the two first limiting blocks, and the two levers are slidably connected inside the sliding groove.

[0009] Furthermore, the outer surface of the first connecting plate is also provided with a second limiting block, and the outer surface of the second connecting plate is also provided with a limiting hole, and the second limiting block is fitted inside the limiting hole.

[0010] Furthermore, a support frame and a drive motor are installed on the upper surface of the placement cabinet, and a connecting rod is provided on the lower surface of the support frame. One end of the connecting rod passes through the placement cabinet and is equipped with a driven gear. The output end of the drive motor passes through the placement cabinet and is equipped with a driving gear. The driving gear and the driven gear are meshed and connected. A duct is rotatably connected inside the support frame. An electric telescopic rod is hinged to one end of the support frame, and the output end of the electric telescopic rod is hinged to the outer surface of the duct.

[0011] Furthermore, the connecting assembly includes a connecting pipe, and the outer surface of the atomizing nozzle is provided with a water inlet pipe. The connecting pipe is threaded into the inside of the water inlet pipe. A clamping block is hinged to the outer surface of the connecting pipe. Two clamping blocks are provided and symmetrically distributed. One clamping block has a limit hole at one end, and the other clamping block has a placement groove at one end. A baffle is installed inside the placement groove. A sliding groove is provided on the inner surface of the placement groove. A limit rod is slidably connected inside the sliding groove. One end of the limit rod passes through the clamping block and is fitted inside the limit hole. A stop is provided on the outer surface of the limit rod. A second spring is sleeved on the outer surface of the limit rod. One end of the second spring is installed on the outer surface of the stop and the other end of the second spring is installed on the outer surface of the baffle. The other end of the limit rod passes through the baffle and is fitted with a pull block.

[0012] Furthermore, a filter screen is installed inside the connecting pipe, the outer surface of the filter screen abuts against the end of the drain pipe, and a squeezing block is provided on the inner surface of the clamping block.

[0013] This utility model has the following beneficial effects:

[0014] (1) This utility model presses two push blocks inward, causing the two push blocks to move inward in the sliding groove. When the push blocks move, they will drive the corresponding first limiting block to slide into the cavity. At the same time, the first spring gradually contracts. When the outer surface of the first limiting block is flush with the outer surface of the connecting block, the connecting block can be pushed outward, causing the connecting block to move outward in the mounting hole. At the same time, the first connecting plate and the second connecting plate gradually separate. When the connecting block is completely separated from the mounting hole, the air duct and the atomizing nozzle can be separated, achieving the effect of easy separation.

[0015] (2) By pulling the pull block outward, the pull block causes the limiting rod to move outward, the second spring gradually contracts, and at the same time, one end of the limiting rod gradually disengages from the inside of the limiting hole. When one end of the limiting rod is completely disengaged from the limiting hole, one of the clamping blocks can be pulled outward, causing the clamping block to rotate axially outward with the hinge point with the connecting pipe as the center. At the same time, the clamping block releases its clamping of the drain pipe, and then the drain pipe and filter screen can be removed from the inside of the connecting pipe, which facilitates the cleaning and replacement of the filter screen and achieves a better practical effect.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-8 As shown, this utility model is a dust suppression spray device, including a base plate 1, with casters 2 mounted on the lower surface of the base plate 1, and a cabinet 3 mounted on the upper surface of the base plate 1. A cabinet door 4 is hinged to one end of the cabinet 3. A pump 5 and a water tank 6 are installed inside the cabinet 3. A duct 7 is mounted on the upper surface of the cabinet 3, with an atomizing nozzle 8 at one end. A first connecting plate 801 is provided at one end of the atomizing nozzle 8. A second connecting plate 701 is provided on the outer surface of the duct 7, with mounting holes on its outer surface. A connecting block 802 is provided on the outer surface of the first connecting plate 801, and the connecting block 802 is used to mount the dust. The connecting block 802 is installed inside the mounting hole. A cavity is opened inside the cavity. A first limiting block 803 is slidably connected inside the cavity. There are two first limiting blocks 803, which are symmetrically distributed. One end of each first limiting block 803 passes through the connecting block 802 and extends outward. A first spring 804 is installed between the two first limiting blocks 803. A suction pipe is installed at the water inlet end of the pump 5. One end of the suction pipe extends into the water storage tank 6. A drain pipe 9 is installed at the drain end of the pump 5. One end of the drain pipe 9 passes through the placement cabinet 3 and is connected to a connecting component 10. A misting nozzle 8 is installed at the other end of the connecting component 10.

[0030] In use, the cabinet door 4 is pulled outward to expose the water tank 6 to the outside. Water is then injected into the water tank 6. Once the water tank 6 is full, the cabinet door 4 is closed. The base plate 1 is pushed and moved by the casters 2. When the dust suppression device moves to the designated position, the extraction pump 5 is started to extract water from the water tank 6 through the extraction pipe. The water in the extraction pump 5 is discharged into the atomizing nozzle 8 through the drain pipe 9 and then sprayed out through the atomizing nozzle 8. The air duct 7 is started to generate airflow, which in turn sprays the water mist from the atomizing nozzle 8 to a distance for dust suppression.

[0031] The outer surface of the connecting block 802 is provided with a sliding groove, one end of which extends into the interior of the cavity. One end of each of the two first limiting blocks 803 is equipped with a lever 805, and both levers 805 are slidably connected to the interior of the sliding groove.

[0032] When it is necessary to disassemble the atomizing nozzle 8, by pressing the two levers 805 inward, the two levers 805 move inward in the slide groove. When the levers 805 move, they will drive the corresponding first limiting block 803 to slide into the cavity. At the same time, the first spring 804 gradually contracts. When the outer surface of the first limiting block 803 is flush with the outer surface of the connecting block 802, the connecting block 802 can be pushed outward, so that the connecting block 802 moves outward in the mounting hole. At the same time, the first connecting plate 801 and the second connecting plate 701 gradually separate. When the connecting block 802 is completely separated from the mounting hole, the separation of the air duct 7 and the atomizing nozzle 8 can be completed.

[0033] The outer surface of the first connecting plate 801 is also provided with a second limiting block 806, and the outer surface of the second connecting plate 701 is also provided with a limiting hole, and the second limiting block 806 is installed inside the limiting hole.

[0034] By using the second limiting block 806 in conjunction with the limiting hole, the stability between the first connecting plate 801 and the second connecting plate 701 can be increased, and the positioning of the first connecting plate 801 and the second connecting plate 701 during installation can also be facilitated.

[0035] The upper surface of the storage cabinet 3 is equipped with a support frame 11 and a drive motor 12. The lower surface of the support frame 11 is provided with a connecting rod. One end of the connecting rod passes through the storage cabinet 3 and is equipped with a driven gear 13. The output end of the drive motor 12 passes through the storage cabinet 3 and is equipped with a driving gear 14. The driving gear 14 and the driven gear 13 are meshed and connected. The air duct 7 is rotatably connected inside the support frame 11. One end of the support frame 11 is hinged to an electric telescopic rod 15. The output end of the electric telescopic rod 15 is hinged to the outer surface of the air duct 7.

[0036] By driving the drive motor 12, the output end of the drive motor 12 drives the drive gear 14 to rotate. Since the drive gear 14 is meshed with the driven gear 13, the rotation of the drive gear 14 drives the driven gear 13 to rotate, thereby causing the connecting rod to rotate axially around the installation point of the placement cabinet 3, so as to achieve the effect of adjusting the direction of the support frame 11, the air duct 7 and the atomizing nozzle 8.

[0037] By activating the electric telescopic rod 15, the output end of the electric telescopic rod 15 moves. When the output end of the electric telescopic rod 15 moves, the air duct 7 rotates axially around the installation point of the support frame 11, thereby achieving the effect of adjusting the angle between the air duct 7 and the atomizing nozzle 8.

[0038] The connecting assembly 10 includes a connecting pipe 1001. A water inlet pipe 807 is provided on the outer surface of the atomizing nozzle 8. The connecting pipe 1001 is threaded into the inside of the water inlet pipe 807. A clamping block 1002 is hinged to the outer surface of the connecting pipe 1001. Two clamping blocks 1002 are provided and symmetrically distributed. One clamping block 1002 has a limit hole at one end, and the other clamping block 1002 has a placement groove at one end. A baffle 1003 is installed inside the placement groove, and a sliding groove is provided on the inner surface of the placement groove. A sliding connection is provided with a limiting rod 1004. One end of the limiting rod 1004 passes through the clamping block 1002 and is fitted inside the limiting hole. A stop block 1005 is provided on the outer surface of the limiting rod 1004. A second spring 1006 is sleeved on the outer surface of the limiting rod 1004. One end of the second spring 1006 is installed on the outer surface of the stop block 1005. The other end of the second spring 1006 is installed on the outer surface of the baffle 1003. The other end of the limiting rod 1004 passes through the baffle 1003 and is fitted with a pull block 1007.

[0039] A filter screen 16 is installed inside the connecting pipe 1001. The outer surface of the filter screen 16 abuts against the end of the drain pipe 9. A pressing block 1008 is provided on the inner surface of the clamping block 1002.

[0040] The filter screen 16 can block impurities in the water source and prevent them from entering the atomizing nozzle 8 and causing blockage. The extrusion block 1008 can extrude the outer surface of the drain pipe 9, increasing the stability of the connection between the clamping block 1002 and the drain pipe 9 and preventing the drain pipe 9 from detaching from the inside of the connecting pipe 1001.

[0041] When the filter screen 16 needs to be replaced, the pull block 1007 is pulled outward, causing the pull block 1007 to move the limiting rod 1004 outward. The second spring 1006 gradually contracts, and at the same time, one end of the limiting rod 1004 gradually disengages from the limiting hole. When one end of the limiting rod 1004 is completely disengaged from the limiting hole, one of the clamping blocks 1002 can be pulled outward, causing the clamping block 1002 to rotate axially outward around the hinge point with the connecting pipe 1001. At the same time, the clamping block 1002 releases its grip on the drain pipe 9. Then, the drain pipe 9 and the filter screen 16 can be removed from the inside of the connecting pipe 1001, which facilitates the cleaning and replacement of the filter screen 16 and achieves a good practical effect.

[0042] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
