[0046] The present application will be described below with reference to the accompanying drawings:

[0047] Figure 1 A schematic diagram of the structure of a gravel storage and transportation system in some embodiments or certain embodiments of the present application is shown. Figure 2 A partial structural schematic diagram of a gravel storage and transportation system in some embodiments or certain embodiments of the present application is shown, with reference to Figure 1 and Figure 2 The present application provides a gravel storage and transportation system, comprising:

[0048] The material discharge device 1 is provided with a receiving end 11 for materials to enter and a plurality of material discharge ends 12 which are spaced apart from each other and for materials to flow out.

[0049] The silo 2 has a feed end 21 and a discharge end 22 at both ends. The feed end 21 is provided with a plurality of feed ports which are spaced around the axis of the silo 2 and connected to the plurality of discharge ends 12 in a one-to-one correspondence. The discharge end 22 is provided with a plurality of discharge ports 221 which are evenly distributed.

[0050] The conveying device 3 is provided with an input portion 31 opposite to the material discharge port 221 for receiving the material, and an output end 32 for outputting the material.

[0051] The transfer device 4 is connected to the output end 32 and is used to receive the material outputted from the transfer output end 32 .

[0052] For materials such as crushed stone, the receiving end 11 of the unloading device 1 in the crushed stone storage and transportation system can receive such materials, and then flow the received materials out from multiple discharge ends 12. The multiple discharge ends 12 of the unloading device 1 are connected to the multiple feed ports of the feed end 21 of the silo 2 in a one-to-one correspondence, so that the materials received by the unloading device 1 can flow into the corresponding feed ports through the multiple discharge ends 12 in batches to enter the silo 2, and the multiple feed ports of the feed end 21 of the silo 2 are spaced around the axis of the silo 2, so that the materials can enter the silo 2 in batches and more evenly for storage, and materials such as crushed stone are more evenly distributed in the silo 2, and the gravity and distribution environment borne by the crushed stone are more even, which can reduce the possibility of segregation of crushed stone due to different gravity or environment and enrichment of stone powder in a certain area, thereby improving the quality of stored crushed stone and other materials. Furthermore, the discharge end 22 of the silo 2 opposite to the feeding end 21 is provided with a plurality of discharge ports 221 that are evenly distributed, so that the crushed stones and other materials in the silo 2 can be evenly discharged to the input part 31 of the conveying device 3, and the crushed stones and other materials in the silo 2 can be evenly distributed as much as possible. The crushed stones stored in the silo 2 and entering the conveying device 3 from the discharge end 22 are of good quality. The conveying device 3 finally transports the received crushed stones and other materials from the output end 32 to the transfer device 4 for transfer. The quality of the crushed stones and other materials is good, and they can be directly used after transfer, which reduces the possibility that the crushed stones and other materials need to be processed after transfer. The application efficiency and effect of the crushed stones and other materials with good quality are good, which solves the technical problem that the application effect and efficiency of the crushed stones are affected to a certain extent.

[0053] It should be noted that the gravel stored and transported by the gravel storage and transport system in this application can be gravel for construction, but the materials that can be stored and transported can also be block materials or powder materials with a volume similar to that of the gravel. Uniform storage and unloading are conducive to improving the quality of the stored and transported materials.

[0054] In some or certain embodiments, the multiple feed ports are divided into at least two first feed ports 211 and at least two second feed ports 212, the diameter of the first feed port 211 is smaller than the diameter of the second feed port 212, and the at least two first feed ports 211 and the at least two second feed ports 212 are staggeredly distributed around the axis of the silo 2.

[0055] The multiple feed ports are divided into at least two first feed ports 211 and at least two second feed ports 212. The caliber of the first feed port 211 is smaller than that of the second feed port 212. The at least two first feed ports 211 and the at least two second feed ports 212 are staggered around the axis of the silo 2. The first feed ports 211 and the second feed ports 212 staggered around the axis of the silo 2 can still achieve uniform falling of materials such as gravel. The first feed port 211 and the second feed port 212 have different calibers and can be connected to different unloading ends 22 in the unloading device 1, which is more flexible.

[0056] In some or certain embodiments, the distance between the second feed inlet 212 and the axis of the silo 2 is greater than the distance between the first feed inlet 211 and the axis.

[0057] For the silo 2 with a larger diameter, in order to ensure the strength of the silo 2, the calibers of the first feed port 211 and the second feed port 212 will not be too large. This is because the distance between the second feed port 212 with a larger caliber and the axis of the silo 2 is controlled to be greater than the distance between the first feed port 211 and the axis. This allows a larger space near the inner wall of the silo 2 to receive more materials relative to the center of the silo 2. The distribution of materials in the silo 2 will be more uniform, which is beneficial to improving the quality of materials such as gravel stored in the silo 2, thereby improving the application effect and efficiency of materials such as gravel.

[0058] It should be noted that the first feed port 211 and the second feed port 212 still serve to receive materials, and the difference between the first feed port 211 and the second feed port 212 is only the difference in diameter or setting position.

[0059] In some or certain embodiments, there may be two first and second feed inlets, the two first feed inlets 211 and the two second feed inlets 212 are staggered around the axis of the silo 2, and the distance between the second feed inlet 212 and the axis of the silo 2 is greater than the distance between the first feed inlet 211 and the axis of the silo 2. While ensuring the strength of the silo 2, the distribution of the materials entering the silo 2 is more uniform.

[0060] In some or certain embodiments, the first feed inlet 211 and the second feed inlet 212 may be both provided in plural numbers and staggered around the axis of the silo 2 .

[0061] In some or certain embodiments, a plurality of feed openings may also be distributed at equal intervals along the circumference of the silo 2 at the feed end 21, so that the material can fall evenly.

[0062] In some or certain embodiments, the unloading device 1 comprises:

[0063] The funnel 13 is arranged at the feeding end 21 and the end with a larger diameter is configured as the receiving end 11, and the end with a smaller diameter of the funnel 13 is the output port 131. The funnel 13 is also provided with at least two discharge pipes that are connected to the receiving end 11 and are spaced apart from each other.

[0064] The reversible belt conveyor 14 is disposed at the feeding end 21 and is provided with a reversible conveyor belt 141 with a middle portion 1411 facing the output port 131 . Both ends of the reversible conveyor belt 141 and the feed pipe are configured as the discharge end 12 .

[0065] For the silo 2 with a larger diameter, the distance that the funnel 13 can transport the material is limited while ensuring the strength of the funnel 13, so a reversible belt conveyor 14 is added. The reversible belt conveyor 14 can transport the material farther and can transport the material at both ends, and can transfer part of the material flowing out of the output port 131 of the funnel 13 to a position farther than the funnel 13, and then allow the material to enter the silo 2. While ensuring uniform material transportation, the unloading device 1 is also relatively stable.

[0066] In some or certain embodiments, the number of discharge pipes of the hopper 13 can be two and distributed on both sides of the hopper 13, the discharge pipes can be connected to the two first feed ports 211, the reversible belt conveyor 14 can be located between the output port 131 of the hopper 13 and the silo 2, and the two ends of the reversible belt conveyor 14 are respectively connected to the two second feed ports 212. The structure is compact, the preparation cost is not high, and it is easy to implement.

[0067] In some or certain embodiments, the material discharge device 1 further includes a plurality of first control valves 15, which are respectively disposed between the output port 131 and at least two material discharge pipes.

[0068] The first control valve 15 may be disposed at the output port 131 or at least two feed pipes to control the connection and disconnection between the output port 131 and the feed pipes to achieve the flow of materials.

[0069] In some or certain embodiments, the first control valve 15 may be a heavy hammer flap valve, or may be other types of mechanical valves, which can control the opening and closing of the corresponding output port 131 or the material discharge pipe and the outflow of the material.

[0070] In some or certain embodiments, the gravel storage and transportation system may further include:

[0071] The incoming material belt 5 has one end spaced from the receiving end 11 and is used for conveying materials to the receiving end 11 .

[0072] Adding the incoming material belt 5 can improve the flexibility of transportation and storage of materials such as crushed stones, and transfer materials such as crushed stones in different positions or directions to the receiving end 11 in the unloading device 1 for storage and transportation.

[0073] It should be noted that, according to needs, one end of the feed belt 5 can be connected to the receiving end 11, or the frame of the feed belt 5 can be fixed to the ground or other fixed positions in the environment where the silo 2 is located.

[0074] In some or certain embodiments, the silo 2 further comprises:

[0075] A plurality of material discharge control valves 23 are provided at the material discharge end 22 and are used to control the opening and closing of the corresponding material discharge ports 221 .

[0076] A discharge control valve 23 is provided at the discharge end 22 of the silo 2 , and a plurality of discharge control valves 23 can be used to control the on and off of the corresponding discharge ports 221 , which can improve the discharge flexibility of the silo 2 and can also control the uniform discharge of materials in the silo 2 .

[0077] In some or certain embodiments, the plurality of discharge ports 221 may be evenly distributed in an array at the discharge end 22 , or the plurality of discharge ports 221 may be evenly arranged in a plurality of concentric circles around the center of the discharge end 22 .

[0078] In some or certain embodiments, the silo 2 further includes a material level meter (not shown) disposed at the feed end 21 and located in the silo 2. The material level meter can display the material level in the silo in real time, guide the uniform dropping and discharge of materials in the silo 2, and avoid the problem of biased silo.

[0079] In some or certain embodiments, the silo 2 further includes at least two material level meters disposed on both sides of the inner peripheral wall of the silo 2. The material level meter can measure the height of materials such as crushed stone in the silo 2. The material level meter is disposed on both sides of the silo 2, and it can be determined whether the crushed stone and other materials stored in the silo 2 are biased. If biased, the material discharge control valve 23 can be used to open the discharge ports 221 at different positions to improve the uniformity of the distribution of materials such as crushed stone in the silo 2.

[0080] In some or certain embodiments, the silo 2 may have a height of 25.5 m, a diameter of 30 m, an effective storage capacity of 20,000 t, a discharge end 22 of the silo 2 may be provided with 13 discharge ports 221, and a discharge control valve 23 may be an electro-hydraulic fan-shaped discharge valve, etc. The specifications are relatively large.

[0081] Figure 3 A schematic diagram of the structure of a transfer device in some embodiments or certain embodiments of the present application is shown, with reference to Figure 3 In some or certain embodiments, the delivery device 3 may include:

[0082] A plurality of first belt conveyors 33 are disposed at the unloading end 22 at intervals. The conveyor belt of each first belt conveyor 33 is opposite to the plurality of unloading ports 221 , and the conveyor belt is configured as an input portion 31 .

[0083] The second belt conveyor 34 is used to receive materials conveyed by the plurality of first belt conveyors 33 , and one end of the second belt conveyor 34 is configured as an output end 32 .

[0084] A plurality of first belt conveyors 33 are arranged at intervals at the discharge end 22, and the conveyor belt of each first belt conveyor 33 is opposite to a plurality of discharge ports 221, and the conveyor belt of each first belt conveyor 33 can be configured as an input portion 31. This structure is more flexible in use, and is easier to implement for silos 2 with larger diameters and specifications. After receiving materials flowing out of discharge ports 221 at different positions, the plurality of first belt conveyors 33 can uniformly convey these materials to the second belt conveyor 34, and then convey these materials to the transfer device 4 for transfer by the second belt conveyor 34.

[0085] In some or certain embodiments, a plurality of first belt conveyors 33 are arranged side by side and the output ends of the plurality of first belt conveyors 33 may be flush, the conveyor belt of the second belt conveyor 34 is located below the output end of the first belt conveyor 33, and there is an angle between the conveying direction of the second belt conveyor 34 and the conveying direction of the first belt conveyor 33. The overall space required is small, and the materials received by the second belt conveyor 34 are also relatively uniform, and the transportation of materials such as crushed stone is relatively stable, which facilitates the collection and transfer of materials from the plurality of second belt conveyors 34, and is conducive to improving the subsequent application efficiency of crushed stone.

[0086] In some or certain embodiments, a guide tube or other structure may be provided between the output end of each first belt conveyor 33 and the conveyor belt of the second belt conveyor 34 to realize the collection and transfer of materials.

[0087] In some or certain embodiments, the transfer device 4 may also include a belt conveyor disposed at the discharge end 22, wherein a conveyor belt of the belt conveyor receives materials flowing out of a plurality of discharge ports 221 and then conveys the materials to the transfer vehicle 44. The transfer device 4 may be used for silos 2 with smaller specifications.

[0088] In some or certain embodiments, the first belt conveyor 33 may be a warehouse belt, and the second belt conveyor 34 may be a main belt. Figure 1 The second belt conveyor 34 on the left side of the middle Figure 1 The output terminal 32 on the right side is essentially an integrated structure, for the purpose of saving space. Figure 1 The second belt conveyor 34 is cut off.

[0089] In some or certain embodiments, the transfer device 4 may include:

[0090] Bracket 41.

[0091] The buffer bin 42 is fixed to the bracket 41 , and a first inlet 421 of the buffer bin 42 is opposite to the output end 32 .

[0092] The metering bin 43 is fixed to the bracket 41 , and the second inlet 431 of the metering bin 43 is opposite to the first outlet 422 of the buffer bin 42 .

[0093] The transfer vehicle 44 is used to receive the material flowing out of the second outlet 432 of the transfer metering bin 43 .

[0094] The support 41 in the transfer device 4 provides support for the buffer bin 42 and the metering bin 43. The buffer bin 42 can receive materials such as gravel from the output end 32 of the transfer device 4, and plays a buffering transition role. The metering bin 43 can receive materials such as gravel from the buffer bin 42, and the metering bin 43 can transfer a certain amount of materials such as gravel to the transfer vehicle 44, which can improve the transfer efficiency of the gravel and improve the application effect and efficiency of the gravel after it is transferred to the destination.

[0095] It should be noted that the buffer bin 42 and the metering bin 43 are containers that require at least one inlet and one outlet. In the present application, the material can enter the buffer bin 42 from the first inlet 421 of the buffer bin 42, then enter the second inlet 431 of the metering bin 43 from the first outlet 422 of the buffer bin 42, and finally flow into the transfer vehicle 44 from the second outlet 432 of the metering bin 43.

[0096] In some or certain embodiments, the transfer device 4 may further include a track 45, and the transfer vehicle 44 may run along the track 45. This can improve the effect of the transfer vehicle 44 in transferring materials such as gravel.

[0097] In some or certain embodiments, the transfer device 4 may also only include a fixed buffer bin 42, and then flow from the buffer bin 42 to the transfer vehicle 44. Stable transfer of materials such as crushed stones can also be achieved.

[0098] In some or certain embodiments, the effective storage capacity of the buffer bin 42 can be 300t; the maximum measuring range of the metering bin 43 can be 100t, and the loading metering accuracy can be ±0.5%; the track 45 can be 1.7km long, the transfer vehicle 44 can be a train, and the driving speed can be 2km / h.

[0099] Figure 4 A flow chart of a method for storing and transporting crushed stone in some embodiments or certain embodiments of the present application is shown, with reference to Figure 4 It can be seen that, based on the same inventive concept, the present application also provides a method for storing and transporting gravel, which is implemented by the gravel storage and transport system as described above. The method for storing and transporting gravel includes:

[0100] S101: Make the receiving end of the unloading device receive the material.

[0101] S102: The unloading device conveys the received materials to the silo.

[0102] S103: The material in the silo is transported to the conveying device.

[0103] S104: The conveying device conveys the received materials to the transfer device.

[0104] S105: The transfer device performs metering transfer on the received materials.

[0105] The structure of the gravel storage and transfer system and its corresponding technical effects can be referred to above, and will not be repeated here. The above process is used to control the material, and after a certain amount of material is stored in the silo, the material can be transported to the transfer device.

[0106] In some or certain embodiments, multiple discharge ports are switchable and one of the multiple discharge ports is located at the center of the discharge end, and the other discharge ports are radially located at the discharge end with the center of the circle as the center. The material in the silo is transported to the conveying device, including:

[0107] With the axis of the silo as the axis of symmetry, the discharge port is opened symmetrically to discharge materials. This can reduce the possibility of the silo being biased, improve the uniformity of the distribution of materials such as gravel in the silo, improve the quality of materials such as gravel, and the discharge method is also more flexible.

[0108] It should be noted that the axis of the silo passes through the center of the circle at the discharge end.

[0109] Combination Figure 3 and Figure 4 In some or some embodiments, the axis of the silo is used as the symmetry axis, and an even number of discharge ports are symmetrically opened for discharge. For example, in a four-port discharge mode, with the center of the circle as the center, four discharge ports with the same radial symmetrical distribution are switched in sequence according to the set switching time to achieve uniform discharge of crushed stone.
