Detailed Implementation

[0022] 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.

[0023] The following is for reference. Figures 1-9 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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 drive device 23. 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 vertical axis to open or close the top opening of the valve cylinder 21. The drive device 23 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.

[0034] For example, the driving device 23 drives the feeding valve plate 22 to rotate counterclockwise around the vertical 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 a closed state to an open state; the drive device 23 drives the feed valve plate 22 to rotate clockwise around the vertical axis by a certain angle, thereby causing the feed valve plate 22 to rotate from a closed state to an open state. Figure 4 The position of the top opening of the valve cylinder 21 shown in the figure has been moved to... Figure 3The 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.

[0035] According to the material storage box assembly of this utility model embodiment, by controlling the operation of the drive device 23, 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 construction efficiency.

[0036] Optionally, the feeding control valve 20 further includes a first connector 24, which includes a vertically extending connecting shaft 241. One end of the connecting shaft 241 is connected to the feeding valve plate 22, and the other end of the connecting shaft 241 is connected to the drive device 23. Optionally, please refer to... Figure 6 The first connecting member 24 also includes a connecting plate 242, through which the connecting shaft 241 is connected to the feeding valve plate 22, thereby facilitating the connection between the connecting shaft 241 and the feeding valve plate 22. Optionally, please refer to... Figure 6 The connecting plate 242 is connected to the feeding valve plate 22 by threaded fasteners (such as bolts), which ensures high connection reliability and convenient disassembly and assembly.

[0037] Please see Figure 5 The valve cylinder 21 is provided with a shaft fixing part 26, and the shaft fixing part 26 has a shaft hole 261 extending vertically. The connecting shaft 241 is rotatably fitted into the shaft hole 261. By providing the shaft fixing part 26 on the valve cylinder 21, the connecting shaft 241 can be provided with rotational support, thereby making the rotation process of the feeding valve plate 22 more stable. Optionally, a bushing or bearing is provided between the shaft fixing part 26 and the connecting shaft 241.

[0038] Please see Figures 3-9 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 connected to the valve cylinder 21, and the driving rotating part 232 is connected to the connecting shaft 241, thereby driving the connecting shaft 241 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 3-9 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 second connecting member 25, through which the connecting shaft 241 is connected to the drive rotation part 232. By making the drive device 23 a rotary cylinder, it achieves fast response, high reliability, and low cost. Furthermore, by providing the second connecting member 25, the connection between the connecting shaft 241 and the drive rotation part 232 becomes flexible and convenient.

[0039] Please see Figure 6 and Figure 9 The second connecting member 25 can be formed as a disc structure. The second connecting member 25 and the drive rotating part 232 are connected by threaded fasteners (such as studs or screws). This not only makes the connection between the second connecting member 25 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 second connecting member 25 and the drive rotating part 232 can also be connected together by welding or snap-fitting.

[0040] The connection method between the connecting shaft 241 and the second connecting member 25 can be selected as needed. For example, in some embodiments, please refer to... Figure 6 The second connecting member 25 is provided with a drive hole 251, and the other end of the connecting shaft 241 is inserted into the drive hole 251. By inserting the connecting shaft 241 into the drive hole 251, the connection between the first connecting member 24 and the second connecting member 25 is realized, thereby realizing the connection between the feeding valve plate 22 and the driving device 23. The connection structure is simple and easy to operate. In other embodiments, please refer to Figures 7-9 The second connecting member 25 is provided with a drive shaft 252, which is connected to the connecting shaft 241 via a coupling 29. The drive shaft 252 and the connecting shaft 241 are connected together by the coupling 29, thereby realizing the connection between the first connecting member 24 and the second connecting member 25, and further realizing the connection between the feeding valve plate 22 and the driving device 23. The connection structure is simple and the operation is convenient.

[0041] 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.

[0042] Please continue reading. Figures 3-9The feeding control valve 20 also includes a mounting bracket 27, which includes a first support plate 271, a second support plate 272, and a third support plate 273. The first support plate 271, the second support plate 272, and the third support plate 273 are all connected to the valve cylinder 21 and are stacked and spaced apart from top to bottom. The first support plate 271 is provided with a first mounting clearance hole, and the second support plate 272 is provided with a second mounting clearance hole. The shaft fixing part 26 passes through the first mounting clearance hole and the second mounting clearance hole and is connected to the first support plate 271 and the second support plate 272. The third support plate 273 is provided with a third mounting clearance hole. The drive body part 231 is connected to the lower part of the third support plate 273, and the drive rotating part 232 passes through the third mounting clearance hole to the upper part of the third support plate 273 to connect with the connecting shaft 241. The drive unit 23 and the shaft fixing part 26 are mounted and fixed on the valve cylinder 21 by the mounting bracket 27, which makes the connection between the drive unit 23 and the shaft fixing part 26 and the valve cylinder 21 more flexible and facilitates the overall structural layout. In addition, the mounting bracket 27 has a simple structure and high connection stability, which makes the overall structure of the feeding control valve 20 more reliable.

[0043] Please continue reading. Figure 5 and Figure 8 The mounting bracket 27 also includes multiple side panels, which are circumferentially spaced around the first support plate 271, the second support plate 272, and the third support plate 273, and each side panel is connected to at least two of the first support plate 271, the second support plate 272, and the third support plate 273. By providing side panels, the overall stability of the mounting bracket 27 can be enhanced, resulting in higher support strength. Optionally, each side panel can be connected to the first support plate 271, the second support plate 272, and the third support plate 273, which further improves the overall stability of the mounting bracket 27.

[0044] Alternatively, please continue reading Figure 5 and Figure 8 The side panels include a first side panel 274, a second side panel 275, and a third side panel 276 spaced apart circumferentially. The first side panel 274 and the third side panel 276 are opposite to each other and are both perpendicularly connected to the side wall of the valve cylinder 21. The second side panel 275 is connected to the side of the first support plate 271, the second support plate 272, and the third support plate 273 away from the side wall of the valve cylinder 21. This makes the overall stability of the mounting bracket 27 higher. Optionally, the side panels, the first support plate 271, the second support plate 272, and the third support plate 273 may be provided with weight-reducing grooves or weight-reducing holes.

[0045] The valve cylinder 21 is provided with a first limiting part 2741. When the feeding valve plate 22 is in the position of blocking the top opening of the valve cylinder 21, please refer to... Figure 3The feeding valve plate 22 abuts against the first limiting part 2741. The valve cylinder 21 is also provided with a second limiting part 2751. When the feeding valve plate 22 is in the open position at the top of the valve cylinder 21, please refer to... Figure 4 The feeding valve plate 22 abuts against the second limiting part 2751.

[0046] By setting a first limiting part 2741 and a second limiting part 2751, and by moving the feeding valve plate 22 to the two extreme positions of the rotatable range, it abuts against the first limiting part 2741 and the second limiting part 2751 respectively. The feeding valve plate 22 is positioned at the extreme position of the rotatable range by the force exerted on the first limiting part 2741 and the second limiting part 2751. This avoids the need to control the feeding valve plate 22 to be positioned at the extreme position by the force exerted on the driving device 23, thereby protecting the driving device 23 and preventing damage to the driving device 23.

[0047] Optionally, please refer to Figures 4-5 The first limiting part 2741 may be provided on the first side panel 274 or the third side panel 276, and the second limiting part 2751 may be provided on the second side panel 275.

[0048] Please see Figures 3-4 The valve cylinder 21 is provided with a support arm 28. When the feeding valve plate 22 is in the open position at the top of the valve cylinder 21, the feeding valve plate 22 is supported on the support arm 28. This can prevent the connecting shaft 241 and the drive device 23 from bearing a large eccentric load when the feeding valve plate 22 is in the open position at the top of the valve cylinder 21.

[0049] Please see Figures 3-9 The feeding valve plate 22 includes a valve plate body 221 and a connecting arm 222. The valve plate body 221 is used to open or close the top opening of the valve cylinder 21, and the connecting arm 222 is used to connect the valve plate body 221 and the drive device 23. This makes the connection between the feeding valve plate 22 and the drive device 23 more convenient.

[0050] Optionally, the valve cylinder 21 may also be equipped with multiple corner cylinders (not shown in the figure). The multiple corner cylinders are arranged at intervals along the circumference of the valve cylinder 21. The cylinder of each corner cylinder is located on the valve cylinder 21. When the feeding valve plate 22 is in the state of closing the top opening of the valve cylinder 21, the pressure arm of each corner cylinder can press against the top of the valve plate. By setting up corner cylinders and making the pressure arm of the corner cylinders press against the top of the valve plate when the feeding valve plate 22 is in the state of closing the top opening of the valve cylinder 21, the feeding valve plate 22 can be pressed tightly against the valve cylinder 21, thereby making the sealing of the top opening of the valve cylinder 21 by the feeding valve plate 22 more secure. This can prevent the material in the storage box 10 from overflowing due to shaking during the operation of the vehicle body.
