Description

Technical Field

[0001] This disclosure relates to the field of emergency rescue machinery, and in particular to a material storage system, a suction device, and a control method for the material storage system. Background Technology

[0002] my country has a vast territory, but it is predominantly mountainous and hilly, accounting for 69% of its total land area. Geological disasters are frequent, mainly manifested as landslides, collapses, debris flows, and ground subsidence. Sudden geological disasters cause severe casualties and economic losses. During on-site rescue operations, confined spaces and situations where people are buried are unsuitable for large earthmoving machinery such as excavators and loaders. Instead, excavator suction trucks are needed, utilizing the high-negative-pressure suction principle to remove materials, thereby improving on-site material clearing efficiency and minimizing secondary injuries to personnel.

[0003] The storage tanks of suction trucks in related technologies have limited capacity, while their suction efficiency is usually high. The tanks fill up quickly, requiring the system to be stopped, unloaded, and restarted. Since the material is drawn into the storage tank under negative pressure, conventional tanks require the door to be opened during unloading. At this point, the pressure inside the tank is the same as the external atmospheric pressure, preventing the suction system from creating a negative pressure state. This prevents material from being drawn into the tank. In rescue operations where time is of the essence, the time spent stopping the suction truck and unloading significantly impacts the efficiency of rescue efforts at the scene.

[0096] my country has a vast territory, but it is predominantly mountainous and hilly, accounting for 69% of its total land area. Geological disasters are frequent, mainly manifested as landslides, collapses, debris flows, and ground subsidence. Sudden geological disasters cause severe casualties and economic losses. During on-site rescue operations, confined spaces and situations where people are buried are unsuitable for large earthmoving machinery such as excavators and loaders. Instead, excavator suction trucks are needed, utilizing the high-negative-pressure suction principle to remove materials, thereby improving on-site material clearing efficiency and minimizing secondary injuries to personnel.

[0097] The storage tanks of suction trucks in related technologies have limited capacity, while their suction efficiency is usually high. The tanks fill up quickly, requiring the system to be stopped, unloaded, and restarted. Since the material is drawn into the storage tank under negative pressure, conventional tanks require the door to be opened during unloading. At this point, the pressure inside the tank is the same as the external atmospheric pressure, preventing the suction system from creating a negative pressure state. This prevents material from being drawn into the tank. In rescue operations where time is of the essence, the time spent stopping the suction truck and unloading significantly impacts the efficiency of rescue efforts at the scene.

[0098] In view of this, in one aspect of the embodiments of this disclosure, a storage system for a suction device is provided, which can improve suction efficiency.

[0099] Figure 1 These are perspective views of some embodiments of the material storage system disclosed herein. Figure 2 This is a front view of some embodiments of the material storage system according to the present disclosure. Figure 3 These are side views of some embodiments of the material storage system according to the present disclosure. Figure 4 This is a connection diagram based on some embodiments of the material storage system disclosed herein, with reference to... Figures 1-4 The storage system includes: a storage mechanism 1, a feed diversion mechanism 3, a discharge mechanism 4, and a processor 5. The storage mechanism 1 is used to temporarily store materials such as sludge and mud pumped by the suction equipment. When the storage mechanism 1 is full, the temporarily stored material can be discharged from the storage mechanism 1 through the discharge mechanism 4 so that the suction operation can continue.

[0100] The storage mechanism 1 has a first silo 11 and a second silo 12. The storage mechanism 1 can receive materials through the feed inlet 2 and temporarily store the materials in the first silo 11 or the second silo 12. The materials include, but are not limited to, soil and rubble generated in mountain disasters such as landslides, collapses, debris flows and ground subsidence.

[0101] The first hopper 11 and the second hopper 12 are, but are not limited to, independently configured. Alternatively, the storage mechanism 1 can be divided into two hoppers, the first hopper 11 and the second hopper 12, by a partition 13. The first hopper 11 and the second hopper 12 can be hoppers with the same capacity and size, or their capacity and size can be adapted to be set separately according to actual working requirements.

[0102] The feeding diversion mechanism 3 is located on the material movement path between the storage mechanism 1 and the feeding port 2. It is configured to selectively connect the feeding port 2 with the first silo 11 or the second silo 12, thereby opening the feeding channel between the feeding port 2 and the first silo 11 and closing the feeding channel between the feeding port 2 and the second silo 12, or opening the feeding channel between the feeding port 2 and the second silo 12 and closing the feeding channel between the feeding port 2 and the first silo 11, so that the first silo 11 or the second silo 12 receives material through the feeding port 2.

[0103] The unloading mechanism 4 is operably connected to the first hopper 11 and the second hopper 12, and is configured to selectively switch the opening and closing of the first hopper 11 and the second hopper 12 so as to unload material from the first hopper 11 or the second hopper 12. The unloading mechanism 4 can open or close the doors at the unloading openings of the first hopper 11 and the second hopper 12 so as to unload material from the first hopper 11 or the second hopper 12, or to keep the first hopper 11 or the second hopper 12 in a closed state.

[0104] The processor 5 is signal-connected to the feeding diversion mechanism 3 and the unloading mechanism 4, and is configured to switch the storage mechanism 1 between a first working state and a second working state through the feeding diversion mechanism 3 and the unloading mechanism 4, so that the first hopper 11 feeds and the second hopper 12 unloads, or the first hopper 11 unloads and the second hopper feeds, so that in the first working state of the storage mechanism 1, the storage mechanism 1 receives material through the first hopper 11 and unloads through the second hopper 12, and in the second working state of the storage mechanism 1, the storage mechanism 1 receives material through the second hopper 12 and unloads through the first hopper 11.

[0105] In this embodiment, the first hopper 11 and the second hopper 12 independently open and close their feeding channels and independently open and close their doors. When the first hopper 11 is feeding material, the material accumulated in the second hopper 12 can be unloaded at the same time. When the first hopper 11 is full and needs to be unloaded, the second hopper 12 can be switched to the feeding state, so that the first hopper 11 unloads material while feeding material into the second hopper 12. The storage mechanism 1 allows the storage operation and the unloading operation to be carried out at the same time, without occupying working time to stop the equipment to switch the storage and unloading states, thereby improving work efficiency and saving rescue time.

[0106] refer to Figure 4In some embodiments, the storage mechanism further includes a level detection mechanism 6, which is disposed in the storage mechanism 1 and configured to detect the level of the first hopper 11 and the second hopper 12. The level detection mechanism 6 includes, but is not limited to, those disposed inside the first hopper 11 and the second hopper 12.

[0107] The processor 5 is signal-connected to the material level detection mechanism 6 and is configured to operate the storage mechanism 1 in a first working state or a second working state according to the material level of the first hopper 11 and / or the material level of the second hopper 12.

[0108] In this embodiment, a material level detection mechanism 6 is set up to monitor the material storage status in the first silo 11 and the second silo 12 in real time. When the material in the first silo 11 exceeds the preset level and is about to fill, the first silo 11 stops feeding and switches to the unloading state, allowing the second silo 12 to continue receiving material for suction. Alternatively, when the material in the second silo 12 exceeds the preset level and is about to fill, the second silo 12 stops feeding and switches to the unloading state, allowing the first silo 11 to continue receiving material for suction. The first silo 11 and the second silo 12 alternately feed and unload, enabling the storage mechanism to continuously maintain the suction operation and achieve high suction efficiency.

[0109] refer to Figure 1 and Figure 3 In some embodiments, the storage mechanism 1 can discharge gas through the vent 7. The storage system also includes a gas diversion mechanism 8, which is disposed on the gas flow path between the storage mechanism 1 and the vent 7 and is configured to selectively connect the vent 7 to the first hopper 11 or the second hopper 12 so that the first hopper 11 or the second hopper 12 exhausts gas through the vent 7.

[0110] The processor 5 is signal-connected to the air diversion mechanism 8 and is configured to connect the air outlet 7 to the first hopper 11 through the air diversion mechanism 8 in the first working state of the storage mechanism 1, so as to create a negative pressure state in the first hopper 11; and to connect the air outlet 7 to the second hopper 12 through the air diversion mechanism 8 in the second working state of the storage mechanism 1, so as to create a negative pressure state in the second hopper 12, which facilitates the improvement of the suction force.

[0111] In this embodiment, the connection state between the air outlet 7 and the storage mechanism 1 can be switched according to the connection state between the feed inlet 2 and the storage mechanism 1. When the first hopper 11 is fed, the air outlet 7 is switched to be connected to the first hopper 11, so that a negative pressure suction environment is formed in the first hopper 11. When the second hopper 12 is fed, the air outlet 7 is switched to be connected to the second hopper 12, so that a negative pressure suction environment is formed in the second hopper 12, thereby improving the suction efficiency.

Figure 9 This is a structural schematic diagram of the first flap assembly according to some embodiments of the storage system disclosed herein, with reference to... Figures 8-9 In some embodiments, the first hopper 11 and the second hopper 12 are separated by a partition 13, which has mounting holes 131. The feeding diversion mechanism 3 includes a second feeding section 36, a fifth driving member 38, and a first flap assembly 37. The second feeding section 36 includes, but is not limited to, taking the form of a pipe.

[0122] The fifth drive unit 38 is disposed between the partition 13 and the first flip plate assembly 37. The processor 5 is signal-connected to the fifth drive unit 38 and is configured to cause the first flip plate assembly 37 to flip toward the first hopper 11 so that the first hopper 11 can receive materials, or to flip toward the second hopper 12 so that the second hopper 12 can receive materials.

[0123] The second feeding section 36 is used to communicate with the feeding port 2 and guide the material entering from the feeding port 2 to the first flap assembly 37. The first flap assembly 37 is disposed in the mounting hole 131 and is located downstream of the second feeding section 36. The first flap assembly 37 can flip between the first hopper 11 and the second hopper 12 relative to the mounting hole 131 to close the first hopper 11 and guide the material to the second hopper 12, or close the second hopper 12 and guide the material to the first hopper 11.

[0124] The first flap assembly 37 includes a flap 371. The bottom of the flap 371 is provided with a connecting hole 373 for connection with a pin at the mounting hole 131, thereby enabling the flap 371 to flip. A sealing structure 372 can be provided on the flap 371. The sealing structure 372 is triangular in shape, so as to seal the connection between the other hopper and the mounting hole 131 when material is guided into one hopper, and improve the airtightness of the guiding hopper.

[0125] In this embodiment, the feeding diversion mechanism 3 can take the form of a second feeding section 36 and a first flap assembly 37. By rotating the first flap assembly 37 between the first hopper 11 and the second hopper 12, the switching of the connection between the feeding port 2 and the first hopper 11 and the second hopper 12 can be completed.

[0126] refer to Figures 1-3 , Figure 8In some embodiments, the unloading mechanism 4 includes a first unloading plate 41 and / or a second unloading plate 42. The first hopper 11 and the second hopper 12 are, but are not limited to, cuboid cavities. The first unloading plate 41 serves as the door of the first hopper 11 and is rotatably connected to it to open the first hopper 11 for unloading or to close it. The first unloading plate 41 is, but is not limited to, located on the side of the first hopper 11 to allow material to be unloaded from both sides of the storage mechanism 1. The pivot of the first unloading plate 41 may be located at the top of the side of the first hopper 11. The unloading mechanism 4 and the feeding channel are located at different positions within the hopper to prevent interference between the unloading and feeding actions.

[0127] The second unloading plate 42 serves as the door of the second hopper 12 and is rotatably connected to the second hopper 12 to open the second hopper 12 for unloading or to close the second hopper 12. The second unloading plate 42 is, but is not limited to, symmetrically arranged with the first unloading plate 41. In the first working state of the storage mechanism 1, the first unloading plate 41 is in contact with the first hopper 11 to close the door of the first hopper 11 so that the first hopper 11 is in a negative pressure suction state. At this time, the second unloading plate 42 can be rotated outward of the second hopper 12 to open the second hopper 12, so that the material accumulated in the second hopper 12 can be unloaded while the first hopper 11 is being fed, thereby improving the suction efficiency of the storage system.

[0128] The first unloading plate 41 can rotate outward relative to the first hopper 11 at an angle ranging from 0 to 80°, and the second unloading plate 42 can rotate outward relative to the second hopper 12 at an angle ranging from 0 to 80°. When the angle is 0°, the first unloading plate 41 closes the first hopper 11, and the second unloading plate 42 closes the second hopper 12. Sealing gaskets can be respectively installed on the doors of the first hopper 11 and the second hopper 12 to cooperate with the first unloading plate 41 and the second unloading plate 42 for sealing.

[0129] In this embodiment, the unloading mechanism 4 may include an unloading plate that can be opened and closed relative to the hopper. In conjunction with the working state of the storage mechanism 1, it can realize that while one hopper is sucking in material, the other hopper can carry out unloading operation, which can speed up the suction efficiency of the storage system.

[0130] refer to Figures 1-3 , Figure 8 In some embodiments, the unloading mechanism 4 further includes a first driving member 411 and / or a second driving member 421. The first driving member 411 is connected between the inner wall of the first hopper 11 and the first unloading plate 41, and the second driving member 421 is connected between the inner wall of the second hopper 12 and the second unloading plate 42.

[0131] The processor 5 is signal-connected to the first drive unit 411 and / or the second drive unit 421 and is configured to open the first hopper 11 or the second hopper 12 via the first drive unit 411 and / or the second drive unit 421 so that the first hopper 11 or the second hopper 12 can unload materials.

[0132] In this embodiment, by setting the first driving component 411 and / or the second driving component 421, the working state of the unloading plate can be switched according to the material level change in the hopper, so that the material storage system can store and unload materials at the same time, thereby improving feasibility.

[0133] refer to Figures 1-3 , Figure 8 In some embodiments, the unloading mechanism 4 further includes a first pusher plate 43 and / or a second pusher plate 44. The first pusher plate 43 is rotatably connected to the first hopper 11 as the bottom plate, so that it can rotate from the bottom of the first hopper 11 outwards, causing the material carried on the surface of the first hopper 11 to rotate outwards with the first hopper 11, thereby pushing the material in the first hopper 11 outwards through the hopper door of the first hopper 11, which includes, but is not limited to, the hopper door on which the first unloading plate 41 is installed. The second pusher plate 44 is rotatably connected to the second hopper 12 as the bottom plate, so that the material in the second hopper 12 can be pushed outwards through the hopper door of the second hopper 12.

[0134] The rotation angle range of the first pusher plate 43 relative to the bottom of the first hopper 11 is 0-80°, and the rotation angle range of the second pusher plate 44 relative to the bottom of the second hopper 12 is 0-80°. When the angle is 0°, the first pusher plate 43 closes the bottom of the first hopper 11, and the second pusher plate 44 closes the bottom of the second hopper 12. Sealing gaskets can also be provided at the bottoms of the first hopper 11 and the second hopper 12 to cooperate with the first pusher plate 43 and the second pusher plate 44, respectively, to improve the sealing degree.

[0135] In this embodiment, by setting a first pusher plate 43 and / or a second pusher plate 44, and by rotating the first pusher plate 43 and the second pusher plate 44, the material can move out of the hopper along the pusher plate under the action of the inclined pusher plate, thereby improving the unloading efficiency.

[0136] refer to Figures 1-3 , Figure 8 In some embodiments, the first pusher plate 43 is connected to the first unloading plate 41 via a first connector 431, and the first pusher plate 43 is configured to rotate with the rotation of the first unloading plate 41; and / or the second pusher plate 44 is connected to the second unloading plate 42 via a second connector 441, and the second pusher plate 44 is configured to rotate with the rotation of the second unloading plate 42.

[0137] In this embodiment, by setting the first connector 431 and the second connector 441, the first pusher plate 43 can be linked with the first unloading plate 41, and the second pusher plate 44 can be linked with the second unloading plate 42, making the unloading operation more efficient.

[0138] refer to Figures 1-3 , Figure 8 In some embodiments, the length of the first connector 431 is adjustable so that when the first unloading plate 41 is in the position of closing the door of the first hopper 11, the first pusher plate 43 seals the bottom of the first hopper 11; and / or the length of the second connector 441 is adjustable so that when the second unloading plate 42 closes the door of the second hopper 12, the second pusher plate 44 seals the bottom of the second hopper 12.

[0139] The first connector 431 and the second connector 441 are, but are not limited to, screws, including two screws with positive and negative threads. By rotating the middle connecting screw, the screws at both ends can be extended or shortened simultaneously, or the length of one screw can be adjusted individually. When the length is adjusted to the appropriate length, it is locked with a lock nut to prevent the length from changing during use.

[0140] The unloading mechanism 4 may also include a proximity switch for detecting whether the first pusher plate 43, the first unloading plate 41, the second pusher plate 44, and the second unloading plate 42 are properly sealed.

[0141] In this embodiment, by adjusting the lengths of the first connector 431 and the second connector 441, the pusher plate can also seal the bottom of the hopper when the unloading plate is in the closed hopper door state, thus achieving better sealing.

[0142] refer to Figures 1-3 , Figure 8 In some embodiments, the unloading mechanism 4 further includes a first guide plate 45 and / or a second guide plate 46. The first guide plate 45 is disposed on the outside of the first hopper 11 and rotatably connected to the bottom of the first hopper 11, and is configured to guide the material in the first hopper 11 to be unloaded along the first guide plate 45.

[0143] The second guide plate 46 is disposed on the outside of the second hopper 12 and is rotatably connected to the bottom of the second hopper 12. It is configured to guide the material in the second hopper 12 to be discharged along the second guide plate 46.

[0144] The angle between the first guide plate 45 and the vertical direction ranges from 0° to 60°, and the angle between the second guide plate 46 and the vertical direction also ranges from 0° to 60°. When the angle is 0°, the first guide plate 45 and the second guide plate 46 are parallel to the vertical direction and are in an unloaded state. When unloading is required, the guide plates can be rotated to a suitable angle first, and then the unloading plate and the pusher plate can be rotated until the material is discharged from the side of the hopper.

[0145] In this embodiment, by setting the first guide plate 45 and / or the second guide plate 46, the material can be guided to move to the side of the storage mechanism 1 when it is unloaded, reducing the risk of the material falling into the bottom of the storage mechanism 1 and affecting the movement of the suction equipment.

[0146] refer to Figures 1-3 , Figure 8 In some embodiments, the unloading mechanism 4 further includes a third drive member 451 and / or a fourth drive member 461. The third drive member 451 is connected between the bottom of the first hopper 11 and the first guide plate 45, and the fourth drive member 461 is connected between the bottom of the second hopper 12 and the second guide plate 46.

[0147] The processor 5 is signal-connected to the third drive unit 451 and the fourth drive unit 461, and is configured to switch the guiding angle of the first guide plate 45 via the third drive unit 451, and to switch the guiding angle of the second guide plate 46 via the fourth drive unit 461. The first drive unit 411, the second drive unit 421, the third drive unit 451 and the fourth drive unit 461 are, but are not limited to, taking the form of hydraulic cylinders.

[0148] In this embodiment, the third drive member 451 and the fourth drive member 461 are provided to facilitate the adjustment of the rotation angle of the guide plate according to the size of the storage mechanism 1 or the storage equipment and the unloading situation, thereby guiding the material to fall to the preset position.

[0149] Figure 10 This is a three-dimensional view of a material distribution mechanism according to some embodiments of the material storage system disclosed herein. Figure 11 A top view of the material distribution mechanism according to some embodiments of the material storage system disclosed herein. Figure 12 This is a cross-sectional view of a material distribution mechanism according to some embodiments of the storage system of this disclosure, with reference to... Figures 10-12 In some embodiments, the storage system further includes a material dispersing mechanism 9, which is disposed within the storage mechanism 1 and has a mounting part 91 and a rotating part 92. The mounting part 91 is connected to the storage mechanism 1, and the rotating part 92 is rotatably connected to the mounting part 91. The surface of the rotating part 92 has a plurality of spaced-apart dropping holes 921. The material dispersing mechanism 9 is configured to disperse and drop material from the feed inlet 2 within the storage mechanism 1.

[0150] The material dispersing mechanism 9 can be installed at the connection between the top of the silo and the first pipeline 321 and / or the second pipeline 331. A bearing 93 is installed outside the mounting part 91, and the rotating part 92 is connected to the mounting part 91 through the bearing 93 so as to rotate around the mounting part 91. The mounting part 91 can be a steel rod or a flexible structure such as a chain, in which case the rotating part 92 can rotate and swing.

[0151] The rotating part 92 is conical with a cone angle of 60° to 135°. The diameter of the discharge hole 921 is 1 / 8 to 1 / 3 of the opening diameter of the rotating part 92. This ensures that the rotating part 92 can both guide the flow and not obstruct the feeding, preventing the material from sticking to the side wall of the silo and allowing the material to be evenly distributed at the bottom of the silo. After the material enters the silo, under the action of the material dispersion mechanism 9, part of the material falls directly from the discharge hole 921, while the other part falls along the inclined surface of the rotating part 92. The rotating part 92 can also adopt an irregular conical structure.

[0152] In this embodiment, by setting the material dispersing mechanism 9, the material can be more evenly distributed in the hopper by the rotation and / or oscillation of the rotating part 92.

[0153] In some embodiments, the air diversion mechanism 8 includes: a first air outlet, a first air inlet, a second air inlet, a second diversion section, and a second rotating plate assembly.

[0154] The first air outlet is connected to the air outlet 7, the first air inlet is connected to the first hopper 11, the second air inlet is connected to the second hopper 12, the second diverter is located between the first air outlet and the first air inlet and between the first air outlet and the second air inlet, and the second rotating plate assembly is located in the second diverter and can rotate relative to the first air inlet and / or the second air inlet.

[0155] The processor 5 is signal-connected to the second rotating plate assembly and is configured to connect the first air outlet to the first air inlet by switching the rotation state of the second rotating plate assembly so that the gas in the first hopper can be discharged through the first air inlet and the first air outlet, or to connect the first air outlet to the second air inlet so that the gas in the second hopper can be discharged through the second air inlet and the first air outlet.

[0156] In this embodiment, the exhaust diversion mechanism 8 can be a structure similar to the feed diversion mechanism 3, so as to cooperate with the feeding state of the first hopper 11 and the second hopper 12, provide a negative pressure state for the hopper, and improve the suction efficiency.

[0157] Figure 13 This is a structural schematic diagram of some embodiments of the suction equipment disclosed herein. In another aspect of the embodiments of this disclosure, a suction equipment is provided, including: a storage system 10 as described above. The suction equipment includes, but is not limited to, dredging vehicles, excavation suction vehicles, rescue suction units, etc., and is used in emergency rescue situations such as geological disasters, or in situations such as non-destructive excavation of underground pipelines and dredging of underground confined spaces in the municipal field.

[0158] In this embodiment, the suction equipment uses a storage system 10, which enables the storage and unloading operations to be carried out independently and simultaneously in different silos, which helps to significantly improve suction efficiency and save rescue and disaster relief time.

[0159] Figure 14 This is a flowchart of some embodiments of the material storage system control method according to the present disclosure, with reference to... Figure 14 In another aspect of this disclosure, a storage system control method based on any of the above-described storage systems is provided, comprising: step S1. Step S1 can be implemented by processor 5 executing instructions.

[0160] In step S1, the material storage mechanism 1 is switched between a first working state and a second working state by the feeding diversion mechanism 3 and the unloading mechanism 4. In the first working state, the material storage mechanism 1 receives material through the first hopper 11 and unloads material through the second hopper 12. In the second working state, the material storage mechanism 1 receives material through the second hopper 12 and unloads material through the first hopper 11.

[0161] In this embodiment, the material storage mechanism 1 is switched between the first working state and the second working state by the feeding diversion mechanism 3 and the unloading mechanism 4, so that the material storage operation and the unloading operation can be carried out independently and simultaneously in different silos, which helps to greatly improve the suction efficiency.

[0162] In some embodiments, the storage system further includes a material level detection mechanism 6, which is disposed in the storage mechanism 1 and configured to obtain the material level in the first hopper 11 and the second hopper 12.

[0163] The operation of switching the storage mechanism 1 between the first working state and the second working state through the feeding diversion mechanism 3 and the unloading mechanism 4 specifically includes: obtaining the material level in the first silo 11 and the material level in the second silo 12 through the material level detection mechanism 6; switching the storage mechanism 1 to the second working state in response to the material level in the first silo 11 being greater than the preset material level; and switching the storage mechanism 1 to the first working state in response to the material level in the second silo 12 being greater than the preset material level.

[0164] In this embodiment, by monitoring the material level in the silo in real time, when the material level in the silo is full, the silo can be switched to the unloading state, and another silo can be switched to the storage state. The first silo 11 and the second silo 12 take turns feeding and unloading, so that the storage mechanism can continuously maintain the suction operation state and achieve high suction efficiency.

[0165] refer to Figure 14 In some embodiments, the storage mechanism 1 can discharge gas through the vent 7. The storage system also includes a gas diversion mechanism 8 disposed on the gas flow path between the storage mechanism 1 and the vent 7, configured to selectively connect the vent 7 to the first hopper 11 or to the second hopper 12, so that the first hopper 11 or the second hopper 12 exhausts gas through the vent 7.

[0166] Accordingly, the material storage system control method may further include step S2. Step S2 can be implemented by executing instructions through processor 5.

[0167] In step S2, in the first working state of the storage mechanism 1, the air outlet 7 is connected to the first silo 11 through the air diversion mechanism 8 so that the first silo 11 forms a negative pressure state. In the second working state of the storage mechanism 1, the air outlet 7 is connected to the second silo 12 through the air diversion mechanism 8 so that the second silo 12 forms a negative pressure state.

[0168] In this embodiment, when the first hopper 11 is fed, the air outlet 7 is switched to be connected to the first hopper 11, so that a negative pressure suction environment is formed in the first hopper 11. When the second hopper 12 is fed, the air outlet 7 is switched to be connected to the second hopper 12, so that a negative pressure suction environment is formed in the second hopper 12, thereby improving the suction efficiency.

[0169] The following describes the control flow of the storage system in some embodiments: When material enters from the inlet 2, one side of the rotating plate of the feeding diversion mechanism 3 is opened first, and the other side of the rotating plate is closed. The air diversion mechanism 8 and its corresponding rotating plate are also opened and closed. Under the action of the material dispersion mechanism 9, the material falls evenly into one of the hoppers. When the level sensor at the top of the hopper detects that the material in that hopper has reached the set volume, a prompt is issued to switch hoppers and unload. Then, the rotating plate corresponding to the other hopper is opened first, followed by the closing of the rotating plate corresponding to the hopper that is already full. When opening the rotating plates, the rotating plate on the side of the air outlet 7 is opened first, followed by the rotating plate on the side of the inlet 2. When closing the rotating plates, the rotating plate on the side of the inlet 2 is closed first. Then, the unloading plate is rotated to a suitable angle, and the pusher plate and guide plate are rotated until the material is completely unloaded. The unloading plate and pusher plate are then reset, and the reset status is detected by a proximity switch. Finally, the guide plate is reset. When another hopper is full, the hopper unloading is switched in a similar manner and sequence.
