It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin connection; or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] like Figure 1-5As shown, the present invention proposes a dust suppression spray structure for sand and gravel storage silos. Its basic support part includes a base plate 1, which can be fixedly installed on the top of the storage silo or at a suitable position nearby by means of anchor bolts, etc. A bracket 2 is fixedly installed on the top of the base plate 1 to support the entire structure. A top block 3 is installed on the top of the bracket 2. The top block 3 can be designed as a cubic or cylindrical structure and serves as the mounting base for the spray mechanism 4.

[0022] Example 1, as Figure 1-3 As shown, the spraying mechanism 4 includes a fixed box 41, a rotating pipe 42, an installation pipe 43, a connecting pipe 44, a spray pipe 45, a limiting component 46, a nozzle 47, and a driving component 48.

[0023] There are four fixed boxes 41, which are fixedly installed on the four outer surfaces of the top block 3. The interior of the fixed box 41 is a hollow cavity for introducing a pressurized water source, and its function is to distribute the water source.

[0024] The rotating tube 42 is rotatably connected to the fixed box 41 on the side away from the top block 3 via a bearing. A sealing gasket, such as a rubber O-ring, is provided at the connection between the fixed box 41 and the rotating tube 42. Its function is to ensure that no water leakage occurs at the connection when the rotating tube 42 rotates.

[0025] The mounting tube 43 and the rotating tube 42 are fixed and connected at the ends away from the fixed box 41. The connecting tube 44 is screwed into the interior of the mounting tube 43 by means of a threaded connection. This threaded connection structure makes the disassembly and assembly of the spray pipe 45 very convenient.

[0026] The end of the spray pipe 45 and the connecting pipe 44 away from the installation pipe 43 is fixedly connected. At the bottom of the spray pipe 45, multiple nozzles 47 are evenly connected along its length. When pressurized water passes through the spray pipe 45, it is atomized and sprayed out by these nozzles 47 to form a water mist covering a wide area.

[0027] By rotating the connecting pipe 44 and the spray pipe 45, the connecting pipe 44 and the spray pipe 45 can be disassembled, which facilitates the cleaning and maintenance of the nozzle 47 or the inside of the pipe, effectively solving the problem of easy clogging of the nozzle 47 and reducing maintenance costs.

[0028] Example 2, as Figure 4 As shown, the limiting component 46 is installed between the spray pipe 45 and the mounting pipe 43 to limit the spray pipe 45.

[0029] The limiting assembly 46 includes a limiting plate 461, a limiting hole 462, an ear plate 463, a limiting rod 464, a fixing plate 465, and a spring 466.

[0030] The limiting plate 461 is fixedly installed on the outside of the spray pipe 45 near the connecting pipe 44. The limiting plate 461 has multiple limiting holes 462 that are evenly arranged in the circumferential direction and extend to the other side.

[0031] Two ear plates 463 are fixedly installed on the outer wall of the mounting tube 43. A limiting rod 464 slides through the two ear plates 463. A fixing plate 465 is installed on the outside of the limiting rod 464. A spring 466 is sleeved on the outside of the limiting rod 464. One end of the spring 466 is connected to the ear plate 463 near the rotating tube 42, and the other end is connected to the fixing plate 465 fixedly installed on the limiting rod 464. Under the preload of the spring 466, the end of the limiting rod 464 away from the fixing plate 465 is pressed into a corresponding limiting hole 462 on the limiting plate 461, thereby limiting the limiting plate 461 and further limiting the spray pipe 45. This prevents the spray pipe 45 from detaching from the connecting pipe 44 and the mounting tube 43 under external force, thus preventing water leakage.

[0032] When installing or disassembling the connecting pipe 44 and the spray pipe 45, the limiting rod 464 needs to be pulled first to disengage it from the limiting hole 462. At this time, the connecting pipe 44 and the spray pipe 45 can be rotated to disassemble them. After installation, the limiting rod 464 is released so that it slides into the corresponding limiting hole 462, thereby limiting the connecting pipe 44 and the spray pipe 45 and preventing them from rotating under external force.

[0033] Example 3, as Figure 5 As shown, the drive assembly 48 is located on the top of the top block 3 and is used to synchronously drive the four rotating tubes 42 to rotate.

[0034] The drive assembly 48 includes a cross U-shaped bracket 481, a rotating shaft 482, a support plate 483, a drive gear 484, a driven gear 485, and a power module 486.

[0035] A cross-shaped U-shaped frame 481 is fixedly installed on the top of the top block 3, with its four arms pointing towards the four fixed boxes 41 respectively. There are four rotating shafts 482, which are rotatably connected to the four arms of the cross-shaped U-shaped frame 481 through bearings and extend outward. There are four support plates 483, which are fixedly installed on the top of the four fixed boxes 41 respectively. The end of the rotating shaft 482 away from the cross-shaped U-shaped frame 481 is also rotatably connected to the inside of the corresponding support plate 483 to obtain stable support. A drive gear 484 is fixedly installed at the end of each rotating shaft 482 near the support plate 483. A driven gear 485 is fixedly installed on the outside of each rotating tube 42. The four drive gears 484 mesh with the four driven gears 485 respectively.

[0036] The power module 486 includes a geared motor 4861, a rotating rod 4862, a driving bevel gear 4863, and a driven bevel gear 4864.

[0037] The geared motor 4861 is fixedly installed on the top of the cross-shaped U-shaped frame 481. The rotating rod 4862 is connected to the output shaft of the geared motor 4861 and extends vertically downward into the interior of the cross-shaped U-shaped frame 481. The driving bevel gear 4863 is fixedly installed at the bottom end of the rotating rod 4862. There are four driven bevel gears 4864, which are fixedly installed at one end of the four rotating shafts 482 that extend into the interior of the cross-shaped U-shaped frame 481. All four driven bevel gears 4864 mesh with the same driving bevel gear 4863.

[0038] The geared motor 4861 is started, which drives the four driven bevel gears 4864 to rotate simultaneously through the active bevel gear 4863, thereby driving the four rotating shafts 482 to rotate synchronously. The rotating shafts 482 transmit power to the rotating pipes 42 through the meshing of the active gears 484 and driven gears 485, and finally drive the four spray pipes 45 to rotate synchronously to achieve rotating spraying. The geared motor 4861 is controlled by a controller.

[0039] Example 3, as Figure 1 As shown, the bottom of each of the four fixed boxes 41 is connected to a water inlet hose, and the other end of these water inlet hoses are connected to a main water supply pipe, which is used to smoothly deliver external water to the rotating sprinkler system.

[0040] Working principle: The dust suppression spray structure used in this sand and gravel storage silo involves an external water pump delivering pressurized water through a water supply pipe and an inlet hose to four fixed boxes 41. The water flows sequentially through a rotating pipe 42, an installation pipe 43, and a connecting pipe 44, finally reaching the spray pipe 45 and being atomized and sprayed out by the nozzle 47. At the same time, the reduction motor 4861 is started, driving the entire drive assembly 48 to work, causing the four spray pipes 45 to rotate slowly while spraying, thereby greatly expanding the coverage area of ​​the water mist and achieving efficient and thorough dust suppression of the internal space of the storage silo.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
