Detailed Implementation

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0024] The following is for reference. Figures 1-6 The present invention describes a storage bin assembly and a mobile intelligent spraying device according to embodiments of the present invention, the mobile intelligent spraying device being used for fire prevention and extinguishing in coal yards.

[0025] It should be noted that the storage bin assembly of this utility model embodiment can be applied to equipment with storage function, including but not limited to the mobile intelligent spraying device described in this application. In this application, the storage bin assembly is used in a mobile intelligent spraying device to store "fly ash," a raw material for fire extinguishing slurry, as an example for illustration, but this should not be construed as a limitation of this application.

[0026] Please see Figures 1-2 The mobile intelligent spraying device includes a vehicle body (not shown) and a spraying part 100 disposed on the vehicle body. The spraying part 100 includes a mixing component, a storage tank component and a spraying pump 40.

[0027] The mixing assembly includes a mixing chamber 30 and a mixing element. The mixing chamber 30 is provided with a feed inlet 31 and a transfer outlet 32. The mixing element is rotatably disposed inside the mixing chamber 30. The slurry inlet of the shotcrete pump 40 is connected to the transfer outlet 32, and the slurry outlet of the shotcrete pump 40 is suitable for connecting to a spray gun or a grouting pipe.

[0028] Specifically, the mixing chamber 30 provides a place for mixing the slurry. The materials required for fire extinguishing spraying enter the mixing chamber 30 through the feed inlet 31 and are mixed with water under the agitation of the mixing components to form fire extinguishing spraying slurry. The fire extinguishing spraying slurry formed by mixing can be discharged from the mixing chamber 30 through the transfer port 32 and sucked into the spraying pump 40 through the slurry suction port. Then it is sprayed or injected into the fire extinguishing operation area (such as coal piles) through the slurry spray outlet.

[0029] The storage bin assembly includes a storage bin 10, which can be used to store fly ash, the raw material for fire extinguishing spraying. The storage bin 10 has a feed inlet 11 on its top wall and a discharge inlet 12 on its bottom wall. The feed inlet 11 is used to add material into the storage bin 10, and the discharge inlet 12 is used to discharge the material stored in the storage bin 10. The discharge inlet 12 of the storage bin 10 can be connected to the feed inlet 31 of the mixing chamber 30 to add material into the mixing chamber 30.

[0030] Optionally, the discharge port 12 of the storage tank 10 and the inlet 31 of the mixing chamber 30 are connected by a material conveying device (such as a screw conveyor), and the material in the storage tank 10 is added to the mixing chamber 30 by the material conveying device. Alternatively, please refer to [link to relevant documentation]. Figures 1-2 The feed inlet 31 is located on the top wall of the mixing chamber 30. The storage tank 10 is located above the mixing chamber 30, and the discharge port 12 and the feed inlet 31 are vertically opposite to each other. The feed inlet 31 and the discharge port 12 are connected, and a discharge control valve 50 is provided between the feed inlet 31 and the discharge port 12. The discharge control valve 50 is used to control the opening and closing between the feed inlet 31 and the discharge port 12.

[0031] In this way, when materials need to be added to the mixing chamber 30, by opening the discharge control valve 50, the materials in the storage tank 10 can fall into the mixing chamber 30 sequentially through the discharge port 12 and the inlet 31 under gravity, without the need for a material conveying device to transport the materials in the storage tank 10 to the mixing chamber 30. This not only eliminates the need for a material conveying device and simplifies the overall equipment structure, but also reduces the equipment's operating energy consumption. Furthermore, since the materials in the storage tank 10 are added directly to the mixing chamber 30 under gravity, there is no accumulation or delay during the material addition process, resulting in high material proportioning accuracy.

[0032] Understandably, to prevent materials from overflowing from the feed inlet 11 during transportation and construction, or to prevent rainwater from entering the storage tank 10 through the feed inlet 11, the feed inlet 11 needs to be sealed when no materials need to be added to the storage tank 10, and opened when materials need to be added to the storage tank 10. In other words, in practical applications, the feed inlet 11 needs to be opened and closed frequently.

[0033] However, existing technologies all involve manually opening or blocking the feed port 11, which is very inconvenient, especially in scenarios where the feed port 11 is located high (e.g., in...). Figures 1-2 In the example shown, workers also need to use a ladder to open or block the feed inlet 11.

[0034] To resolve the above technical issues, please refer to Figures 1-4 The storage bin assembly in this embodiment further includes a feeding control valve 20, which includes a valve cylinder 21, a feeding valve plate 22, and a driving device. The valve cylinder 21 is disposed on the top wall of the storage bin 10, and the bottom opening of the valve cylinder 21 is opposite to the feeding port 11. The feeding valve plate 22 is rotatably connected to the valve cylinder 21 about a horizontal axis to open or close the top opening of the valve cylinder 21. The driving device is disposed on the valve cylinder 21 and connected to the feeding valve plate 22 to drive the feeding valve plate 22 to rotate, thereby realizing the opening and closing of the feeding port 11.

[0035] For example, the driving device drives the feeding valve plate 22 to rotate counterclockwise around the horizontal axis by a certain angle, thereby causing the feeding valve plate 22 to move from a position where it is normally closed to ... Figure 3 The position of the top opening of the sealing valve cylinder 21 shown is moved to... Figure 4 The position of the open top opening of the valve cylinder 21 shown in the diagram allows the feed port 11 to switch from the closed state to the open state; the drive device drives the feed valve plate 22 to rotate clockwise around the horizontal axis by a certain angle, thereby causing the feed valve plate 22 to rotate from the closed state to the open state. Figure 4 The position of the top opening of the valve cylinder 21 shown in the figure has been moved to... Figure 3 The position of the top opening of the sealing valve cylinder 21 shown in the figure allows the feed port 11 to switch from the open state to the closed state.

[0036] According to the material storage box assembly of this utility model embodiment, by controlling the operation of the drive device, the feeding valve plate 22 can be controlled to automatically open or block the top opening of the valve cylinder 21, thereby realizing the automatic opening and closing of the feeding port 11. The structure is simple and easy to operate, and no manual operation of the feeding valve plate 22 is required, which can further improve the construction efficiency.

[0037] Please see Figures 3-6 The valve cylinder 21 is provided with a bearing seat, and the bearing seat defines a shaft hole extending horizontally. The feeding valve plate 22 includes a valve plate body 221 and a connecting shaft 222. The valve plate body 221 is used to open or close the top opening of the valve cylinder 21. The connecting shaft 222 extends horizontally and has a body section 2221, a rotating support section, and a drive connection section 2224. The body section 2221 is connected to the valve plate body 221, the rotating support section is rotatably fitted into the shaft hole, and the drive connection section 2224 is connected to the drive device 23. By providing a bearing seat on the valve cylinder 21, the connecting shaft 222 can be provided with rotational support, making the rotation process of the feeding valve plate 22 smooth.

[0038] Alternatively, please continue reading Figures 3-6 The feeding valve plate 22 also includes a connecting arm 223, which is used to connect the valve plate body 221 and the connecting shaft 222. This makes the connection between the valve plate body 221 and the connecting shaft 222 more flexible and convenient.

[0039] Please refer to this carefully. Figures 5-6 The rotating support section includes a first rotating support section 2222 and a second rotating support section 2223, which are respectively connected to both ends of the body section 2221. A drive connection section 2224 is connected to the end of the second rotating support section 2223 furthest from the first rotating support section 2222. The bearing includes a first bearing 24 and a second bearing 25 spaced apart in a horizontal direction. The first bearing 24 defines a first shaft hole extending in a horizontal direction, and the second bearing 25 defines a second shaft hole extending in a horizontal direction. The first rotating support section 2222 is rotatably fitted into the first shaft hole, and the second rotating support section 2223 is rotatably fitted into the second shaft hole. A first bushing (e.g., a copper bushing) may be provided between the first rotating support section 2222 and the first shaft hole, and a second bushing (e.g., a copper bushing) may be provided between the second rotating support section 2223 and the second shaft hole. By making the rotating support section include a first rotating support section 2222 and a second rotating support section 2223, and the first rotating support section 2222 and the second rotating support section 2223 are respectively connected to the two ends of the body section 2221, and the valve cylinder 21 is provided with a first bearing seat 24 and a second bearing seat 25, the rotation process of the feeding valve plate 22 can be made more stable.

[0040] Please see Figures 3-6 The driving device 23 includes a driving body 231 and a driving rotating part 232 that can rotate relative to the driving body 231. The driving body 231 is disposed on the valve cylinder 21, and the driving rotating part 232 is connected to the driving connecting section 2224, thereby driving the connecting shaft 222 to rotate, which in turn drives the feeding valve plate 22 to rotate to realize the opening and closing of the feeding port 11. Optionally, please refer to Figures 3-6 The drive device 23 is a rotary cylinder. The cylinder body forms the drive body 231, and the turntable forms the drive rotation part 232. The feeding control valve 20 also includes a connector 26, and the drive connection section 2224 is connected to the drive rotation part 232 through the connector 26. By making the drive device 23 a rotary cylinder, it has a fast response speed, high reliability, and low cost. In addition, by providing the connector 26, the drive connection section 2224 is connected to the drive rotation part 232, thereby making the connection between the drive connection section 2224 and the drive rotation part 232 flexible and convenient.

[0041] Please see Figure 6The connector 26 can be formed as a disc structure, and the connector 26 and the drive rotating part 232 are connected by threaded fasteners (such as studs or screws). This not only makes the connection between the connector 26 and the drive rotating part 232 stable and reliable, but also facilitates disassembly and assembly. Of course, this application is not limited to this. In some other embodiments, the connector 26 and the drive rotating part 232 can also be connected together by welding or snap-fitting.

[0042] The connection method between the connector 26 and the drive connecting segment 2224 can also be selected according to actual needs. For example, in some examples, the connector 26 is provided with a drive hole, and the drive connecting segment 2224 is inserted into the drive hole. By inserting the drive connecting segment 2224 into the drive hole, the connection between the connector 26 and the drive connecting segment 2224 is achieved. The connection structure is simple and easy to operate. In other examples, the connector 26 is provided with a drive shaft 261, and the drive shaft 261 is connected to the drive connecting segment 2224 through a coupling. In still other examples, please refer to... Figure 6 The connecting member 26 is equipped with a drive shaft 261, which is connected to the drive connecting section 2224 via a gear assembly 27. By connecting the drive shaft 261 and the drive connecting section 2224 via the gear assembly 27, not only can the connection between the two be achieved, but the transmission ratio can also be changed. In addition, the drive connecting section 2224 and the drive shaft 261 can be arranged vertically at intervals, which makes the overall layout of the feeding valve plate 22 more reasonable.

[0043] For further information, please refer to [link / reference]. Figure 6 The gear assembly 27 includes a large gear 271 and a small gear 272 that mesh with each other. The large gear 271 is connected to the drive shaft 261, and the small gear 272 is connected to the drive connection section 2224. In this way, when the large gear 271 drives the small gear 272 to rotate as the driving wheel, the speed of the small gear 272 will increase, thereby realizing speed-up transmission.

[0044] Of course, the drive device 23 in this application is not limited to the rotary cylinder described above. In some other embodiments, the drive device 23 may also be an electric motor or a rotary hydraulic cylinder, etc.

[0045] Please see Figures 3-6The feeding control valve 20 also includes a mounting bracket 28, which includes a first support plate 281, a second support plate 282, and a third support plate 283. The first support plate 281, the second support plate 282, and the third support plate 283 are all connected to the valve cylinder 21 and are arranged in a horizontally stacked and spaced manner. A first shaft seat 24 is connected to the first support plate 281, a second shaft seat 25 is connected to the second support plate 282, a drive body part 231 is connected to the third support plate 283, at least a portion of the drive connecting section 2224 is located on the side of the second support plate 282 facing the third support plate 283, and at least a portion of the drive rotating part 232 is located on the side of the third support plate 283 facing the second support plate 282 to be connected to the drive connecting section 2224. By setting up the mounting bracket 28 and connecting the first bearing seat 24, the second bearing seat 25, and the drive body part 231 to the first support plate 281, the second support plate 282, and the third support plate 283 respectively, the connection between the first bearing seat 24, the second bearing seat 25, and the drive body part 231 and the valve cylinder 21 is realized. This makes the connection between the first bearing seat 24, the second bearing seat 25, the drive body part 231 and the valve cylinder 21 flexible and convenient, and the mounting bracket 28 has high support stability, thereby improving the reliability of the connection between the first bearing seat 24, the second bearing seat 25, the drive body part 231 and the valve cylinder 21.

[0046] Please see Figures 5-6 The first support plate 281 has a first mounting clearance hole 2811, and the second support plate 282 has a second mounting clearance hole 2821. Both the first mounting clearance hole 2811 and the second mounting clearance hole 2821 are non-closed holes with notches. The connecting shaft 222 can be positioned in the first mounting clearance hole 2811 and the second mounting clearance hole 2821 through the notches. The first shaft seat 24 is connected to the side of the first support plate 281 away from the second support plate 282, and the first shaft hole and the first mounting clearance hole 2811 are opposite each other. The second shaft seat 25 is located on the side of the second support plate 282 away from the first support plate 281, and the second shaft hole and the second mounting clearance hole 2821 are opposite each other. This facilitates the assembly between the connecting shaft 222 and the first shaft seat 24 and the second shaft seat 25.

[0047] Please continue reading. Figures 5-6 The third support plate 283 is provided with a third mounting clearance hole 2831. The drive body part 231 is located on the side of the third support plate 283 away from the second support plate 282. The drive rotating part 232 passes through the third mounting clearance hole 2831 to the side of the third support plate 283 facing the second support plate 282 to facilitate connection with the connecting shaft 222.

[0048] Please see Figures 3-6The mounting bracket 28 also includes a fourth support plate 284, which is vertically connected to the bottom of the first support plate 281, the second support plate 282, and the third support plate 283. This improves the structural stability of the mounting bracket 28, making the support more stable and reliable. The first support plate 281, the second support plate 282, the third support plate 283, and the fourth support plate 284 may also be provided with weight-reducing holes or grooves, which can reduce the overall weight of the feeding control valve 20 while ensuring the overall structural strength of the mounting bracket 28.

[0049] Please see Figures 3-6 A support limiting rod 285 is provided between the first support plate 281 and the second support plate 282, and a limiting part 224 is provided on the feeding valve plate 22. When the feeding valve plate 22 is in the open position at the top of the open valve cylinder 21 (see [reference]). Figure 4 The limiting part 224 abuts against the support limiting rod 285, thereby enabling the feeding valve plate 22 to be positioned when the top opening of the valve cylinder 21 is opened, without having to control the positioning of the feeding valve plate 22 at that position by applying force to the rotating cylinder, thus avoiding damage to the rotating cylinder due to the force applied to the rotating cylinder.

[0050] Understandably, when the feeding valve plate 22 is in the closed position at the top opening of the valve cylinder 21, as... Figure 3 As shown, the feeding valve plate 22 abuts against the upper edge of the valve cylinder 21, thereby enabling the feeding valve plate 22 to be positioned when the top opening of the valve cylinder 21 is closed, without the need to control the positioning of the feeding valve plate 22 at this position by applying force through a rotating cylinder.
