[0002] A building warehouse is a modern warehouse that uses a multi-story building structure as storage space. It is usually a steel or concrete building with more than 5 floors. It combines automated equipment to achieve efficient storage and management. Compared with traditional flat warehouses, it has the advantages of small footprint, full space utilization, and reasonable economic benefits.

[0003] In order to improve the sealing effect when storing grain, multiple independent storage areas for bulk grain are usually set up on each floor of a building warehouse. In the process of transporting the bulk grain to each storage area, a belt conveyor or suspension equipment is usually used to transport the bulk grain to the top of the building warehouse, and then multiple chutes running through the floors are used to transport the bulk grain to the storage area. The airtightness of the entire transportation process is poor, which will cause a large amount of dust to spread outward, seriously reducing the air quality near the building warehouse.

[0015] The present invention is further configured such that: the opening width of the discharge port gradually narrows from one end to the other end, and the direction in which the discharge port gradually narrows is consistent with the movement direction of the arc gate to close the discharge port.

[0016] By adopting the above technical solution, the discharge port adopts a tapered design, which can gradually reduce the discharge amount during the closing process of the discharge port, thereby effectively preventing the bulk grain from being cut into pieces by the scraper or gate during the falling process, thereby reducing the breakage rate of the bulk grain.

DETAILED DESCRIPTION

[0036] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0037] Reference Figure 1-Figure 9 , is a bulk grain transportation system for a building warehouse disclosed in the present invention, comprising a feeding mechanism 1, which is used to feed the bulk grain to be stored into the building warehouse; The lifting mechanism 2 is used to lift the bulk grain to the top of the building warehouse at the discharge end of the feeding mechanism 1; The material distribution mechanism 3 is used to distribute and transport the bulk grain to the storage area at the discharge end of the lifting mechanism 2. The material distribution mechanism 3 includes a material distribution pipe group, and the discharge ends of the material distribution pipe group are distributed in the storage areas on different floors; The pipelines of the annular conveying mechanism 4, the feeding mechanism 1, the lifting mechanism 2, the dividing mechanism 3 and the annular conveying mechanism 4 are sealed and connected. Multiple annular conveying mechanisms 4 are independently distributed in storage areas on different floors, and are used to convey bulk grain to the corresponding storage area at the discharge end of the dividing mechanism 3; The annular conveying mechanism 4 includes an annular feed pipeline 5 and a circulating conveyor 6 for conveying bulk grain in the annular feed pipeline 5. The annular feed pipeline 5 is sealed and connected with the discharge end of the distribution pipe group. The annular feed pipeline 5 is provided with a plurality of discharge ports 51 which can be opened and closed independently and are arranged at different positions, as well as a sealing mechanism for opening and closing the discharge ports 51.

[0038] After the bulk grain transport vehicle moves to the automobile unloading station, the bulk grain in the transport vehicle is unloaded into the feeding mechanism 1 and transported to the lifting mechanism 2 through the discharging end of the feeding mechanism 1. The lifting mechanism 2 lifts the bulk grain to the top of the building warehouse and transports it to the dividing mechanism 3. The dividing mechanism 3 then distributes the bulk grain to the annular conveying mechanism 4 in each storage area through the dividing pipe group. Finally, the opening and closing of the discharge ports 51 at different positions are controlled by the sealing mechanism to control the landing point of the bulk grain in the storage area, ensure that the bulk grain falls evenly into the storage area for storage, and avoid local accumulation or scattered congestion of the bulk grain.

[0039] Reference Figure 3 The feeding mechanism 1, the lifting mechanism 2, the dividing mechanism 3 and the annular conveying mechanism 4 are sealed and connected through pipelines, which can ensure that the entire process of bulk grain entering the warehouse is carried out in a closed environment, effectively preventing dust from overflowing during transportation, and reducing environmental pollution while improving the sealing of the storage area, effectively preventing air from entering the interior of the storage area, and reducing the hidden dangers of grain mold and deterioration.

[0040] Reference Figure 3 The feeding mechanism 1 includes a feeding pipe 11. The feeding end of the feeding pipe 11 is provided with a dust collector 12 for removing dust from the bulk grain entering the warehouse. The dust collector 12 adopts a modular closed dust removal system. The modular closed dust removal system belongs to the prior art and will not be described in detail in this application. The dust collector 12 is used to remove dust from the incoming grain, which can ensure that impurities and dust in the bulk grain are fully separated and effectively prevent dust diffusion.

[0041] A feed conveyor for conveying bulk grain to the lifting mechanism 2 is installed inside the feed pipe 11. The feed conveyor belongs to the prior art and will not be described in detail in this application. The feed conveyor can be used to convey the bulk grain in the feed pipe 11 to the lifting mechanism 2.

[0042] During the specific implementation process, the dust collector 12 is installed in the truck unloading station. When the bulk grain transport truck moves to the truck unloading station, the end of the truck bed of the bulk grain transport truck enters the interior of the dust collector 12. When the truck bed gradually tilts, the bulk grain falls into the dust collector 12 through the truck bed for dust removal to prevent dust from spreading outward during feeding. At the same time, the dust collector 12 can perform preliminary screening of the bulk grain, effectively remove impurities and dust in the grain, and ensure the cleanliness of the grain and the storage environment.

[0043] When the bulk grain falls into the feed pipe 11, the motor of the feed conveyor starts to operate, and the scraper moves inside the feed pipe 11 through the meshing transmission of the sprocket and the scraper chain, thereby continuously conveying the bulk grain to the lifting mechanism 2 inside the feed pipe 11, and allowing the bulk grain to enter the lifting mechanism 2 through the discharge end of the feed pipe 11.

[0044] Reference Figure 3The lifting mechanism 2 includes a lifting pipe 21. The feed end of the lifting pipe 21 is sealed and connected to the discharge end of the feed pipe 11. A bucket elevator is installed inside the lifting pipe 21 to lift the bulk grain to the distribution pipe group. The bucket elevator belongs to the existing technology and will not be described in detail in this application. The bucket elevator can be used to transport the bulk grain in the lifting pipe 21 to the distribution pipe group. It has high sealing and stability during the lifting process to achieve low residue and low breakage lifting and transportation of the bulk grain.

[0045] In the further implementation process, a plurality of lifting pipes 21 can be set according to the number of floors of the building warehouse, and the plurality of lifting pipes 21 are distributed in a stepped manner, wherein the discharge end of the lower position lifting pipe 21 is sealed and connected with the feed end of the adjacent higher position lifting pipe 21, thereby forming a multi-stage lifting structure, and lifting the bulk grain in sections, which can reduce the lifting pressure of the bucket elevator on the bulk grain, extend the service life of the bucket elevator, and facilitate the rapid transportation of the bulk grain to the storage areas on different floors.

[0046] Reference Figure 3 The distribution pipe group includes a transverse pipe 31 and multiple distribution pipes 32. The transverse pipe 31 is transversely fixed on the top of the building warehouse, and the feed end of the transverse pipe 31 is sealed and connected with the discharge end of the lifting pipe 21. The distribution pipe 32 is vertically fixed on the outer wall of the building warehouse. The feed end of each distribution pipe 32 is sealed and connected with the transverse pipe 31 respectively. A distribution conveyor for distributing bulk grain to each distribution pipe 32 is installed inside the transverse pipe 31. The distribution conveyor belongs to the prior art and will not be described in detail in this application. The distribution conveyor can be used to distribute the bulk grain in the transverse pipe 31 to each distribution pipe 32 for transportation, so as to facilitate the transportation of bulk grain to different storage areas.

[0047] Reference Figure 4-Figure 7 The capping mechanism corresponds to the discharge port 51 one by one, and the opening and closing of each discharge port 51 can be independently controlled. The capping mechanism includes a sealed buffer bin 7, an arc gate plate 71, and a driving component for driving the arc gate plate 71 to slide. The sealed buffer bin 7 cover is arranged at the bottom of the discharge port 51 and is fixedly connected to the annular feed pipeline 5 by bolts. The arc gate plate 71 fits the outer surface of the annular feed pipeline 5 and is slidably connected to the sealed buffer bin 7. The driving component includes a rack 72 and a gear 73. The bar 72 is integrally formed with the bottom of the arc gate plate 71, and the gear 73 is rotatably arranged inside the sealed buffer bin 7 through the rotating shaft and meshes with the rack 72 for transmission. A motor for controlling the rotation of the gear 73 is installed on the outer side of the sealed buffer bin 7 through bolts. When the motor runs and drives the gear 73 to rotate, the meshing transmission of the gear 73 and the rack 72 can drive the arc gate plate 71 to slide on the sealed buffer bin 7, thereby controlling the corresponding discharge port 51 to be opened or closed, so as to facilitate the regulation of the landing position of the bulk grain.

[0048] Reference Figure 6The discharge port 51 adopts a tapered teardrop-shaped opening structure, and the opening width of the discharge port 51 gradually narrows from one end to the other end, and the direction in which the discharge port 51 gradually narrows is consistent with the movement direction of the arc gate 71 to close the discharge port 51. Compared with the traditional discharge port structure, which is closed by reducing the length of the opening, it still has a large discharge amount when closed. In the process of closing the discharge port 51, the length and width of the discharge port 51 structure are synchronously reduced near the end of the discharge port 51 in the present embodiment, so that the discharge amount of the discharge port 51 can be gradually reduced during the closing process, and the discharge amount when the discharge port 51 is closed can be reduced, thereby effectively preventing the bulk grain from being cut into pieces by the scraper or gate during the falling process, and reducing the breakage rate of the bulk grain.

[0049] Reference Figure 5 and Figure 7 The bottom of the sealed buffer bin 7 is an open structure, and a sealing cover 75 is provided at the bottom of the sealed buffer bin 7. The length and width of the sealing cover 75 are both larger than the opening structure at the bottom of the sealed buffer bin 7, and a sealing member 77 is provided on the side of the sealing cover 75 close to the sealed buffer bin 7. The sealing member 77 adopts a rubber sealing gasket bonded and fixed to the sealing cover 75, and the rubber sealing gasket is fitted with the inner wall of the sealed buffer bin 7. One end of the sealing cover 75 is rotatably connected to the sealed buffer bin 7 through a rotating shaft. An elastic control member 76 for controlling the opening and closing of the sealing cover 75 according to the weight of the bulk grain is provided on the outer wall of the sealed buffer bin 7. The elastic control member 76 is symmetrically arranged on the outer side of the sealed buffer bin 7. The elastic control member 76 can adopt a delayed air spring, a hydraulic spring or a controllable gas spring to control the opening and closing of the sealing cover 75.

[0050] The cam 75 is in a closed position when the packing liner 71 is in a closed position, and the cam 75 is in a closed position when the packing liner 71 is in a closed position. The sealing cover 75 gradually contracts inwardly and drives the sealing cover 75 to gradually open to control the bulk grain from falling into the storage area. When the arc gate plate 71 controls the discharge port 51 to gradually close, as the bulk grain falling on the sealing cover 75 gradually decreases, the weight detected by the weight sensor will decrease. At this time, the controllable gas spring is controlled to gradually extend outward and the sealing cover 75 is gradually closed, gradually reducing the opening size of the gravity port 74. When the discharge port 51 is completely closed, the sealing cover 75 is quickly closed. Through the cooperation of the sealing cover 75 and the elastic control member 76, the bottom of the discharge port 51 can be kept in a closed state when the discharge port 51 is not fully opened, thereby further improving the air tightness near the discharge port 51. During the closing process of the discharge port 51, the sealing cover 75 is controlled to gradually close, quickly reducing the opening size at the discharge port 51, effectively blocking air infiltration, and enhancing the moisture-proof effect inside the storage area.

[0051] In the further implementation process, the sealing member 77 adopts an inflatable sealing strip, which is bonded and fixed to the sealing cover 75, and the inflatable sealing strip is arranged between the sealing cover 75 and the inner wall of the sealed buffer bin 7. When the sealing cover 75 is closed, air is inflated into the inside of the inflatable sealing strip, and the sealing strip is expanded to be completely in contact with the inner wall of the sealed buffer bin 7. When the sealing cover 75 needs to be opened, the air pressure inside the inflatable sealing strip is reduced so that the sealing cover 75 can be easily opened. Through this design, the sealing effect of the bottom of the sealed buffer bin 7 can be further improved, effectively blocking air infiltration and enhancing the moisture-proof effect inside the storage area.

[0052] Reference Figure 4 and Figure 8The circulating conveyor 6 includes a sprocket 61, a conveying chain 62, a conveying scraper 63 and a driving device. The sprocket 61 is installed at the corner of the annular feed pipeline 5 and is meshed with the conveying chain 62 for transmission. The conveying chain adopts a sleeve roller chain, and a number of evenly distributed wing plates are welded on both sides of the conveying chain. The conveying scraper 63 is fixed on the wing plate by bolts, so that the conveying scraper 63 is convenient for maintenance or replacement. The driving device is coaxially driven by the motor and the sprocket 61. When the motor drives the sprocket 61 to rotate, the conveying chain 62 can drive the conveying scraper 63 to convey the bulk grain.

[0053] In this embodiment, the outer edge of the conveying scraper 63 is arc-shaped and fits with the inner wall of the annular feed pipeline 5, which can avoid material clamping between the conveying scraper 63 and the inner wall of the annular feed pipeline 5, effectively reducing the breakage rate of bulk grain, and the circular conveying scraper 63 is matched with a sleeve roller chain, so that the bulk grain has a higher transportation effect and effectively reduces the required power, thereby achieving high-yield and long-distance transportation.

[0054] Reference Figure 8 and Fig. 9 The interior of the conveying scraper 63 is designed to be a hollow cross-section structure, and a notch 631 for avoiding the sprocket 61 is opened on the side close to the sprocket 61 and the conveying chain 62. The design of the notch 631 can prevent the conveying scraper 63 from contacting and rubbing with the sprocket 61 at the corner of the annular feeding pipeline 5, thereby reducing the transmission resistance of the sprocket 61 and the conveying chain 62. Compared with the traditional integral solid scraper matching gear 73 for transmission, since the pitch of the sprocket 61 does not need to consider the interference problem between the conveying scraper 63 and the conveying chain 62, the pitch of the sprocket 61 can be greatly reduced, the number of teeth of the sprocket 61 can be increased, and the number of teeth of the sprocket 61 can be increased to more than 15 teeth, thereby improving the transmission efficiency of the sprocket 61 and the conveying chain 62, and making the operation between the sprocket 61 and the conveying chain 62 smoother, effectively improving the transportation efficiency of bulk grain.

[0055] The annular feed pipeline 5 includes a plurality of straight tube bodies 52 and a corner sleeve 53 connecting the straight tube bodies 52 to form an annular pipeline structure. The corner sleeve 53 is located at the corner of the annular feed pipeline 5. The sprocket 61 is rotatably installed in the corner sleeve 53. An inner sleeve 54 communicating with the straight tube body 52 is provided on the inner side of the corner sleeve 53. The inner sleeve 54 and the straight tube body 52 are tightly connected so that the annular feed pipeline 5 has a good sealing effect. At the same time, the conveying scraper 63 fits the inner wall of the inner sleeve 54. The inner sleeve 54 is provided with a transmission port 55 for the sprocket 61 to pass through. After the edge of the sprocket 61 extends into the transmission port 55, it meshes with the conveying chain 62 in the inner sleeve 54 for transmission. The design of the inner sleeve 54 can improve the smoothness of the loose grain at the corner, so that the loose grain can be quickly and smoothly transferred at the corner of the annular feed pipeline 5, and effectively prevent the loose grain from contacting or rubbing with the sprocket 61 or the conveying chain 62 at the corner.

[0056] During the specific implementation process, the annular feed pipeline 5 has at least four corners, and a tensioning wheel is installed in the corner sleeve 53 at one of the corners. The tensioning wheel can slide along the corner sleeve 53 and adjust the tension of the conveying chain 62. A motor is installed on the corner sleeve 53 at one of the corners through bolts, and the motor can drive the sprocket 61 to rotate so that the sprocket 61 and the conveying chain 62 are transmitted. In addition, at the remaining corners of the annular feed pipeline 5, an unpowered sprocket 61 can be selected or a motor can be installed to further drive the sprocket 61 according to the length or power requirement of the conveying annular feed pipeline 5.

[0057] In another embodiment, the feeding mechanism 1, the lifting mechanism 2, the dividing mechanism 3 and the annular conveying mechanism 4 all use the above-mentioned circulating conveyor 6 to convey the bulk grain in the pipeline. By conveying the bulk grain in the pipeline by the circulating conveyor 6, efficient and stable transportation of the bulk grain can be achieved, ensuring the integrity and continuity of the bulk grain during the transportation process, and effectively preventing congestion or breakage of the bulk grain during the transportation process.

[0058] In this embodiment, in order to further improve the sealing performance of the storage area, the cross pipe 31, the distribution pipe 32 and the feed end of the annular feed pipeline 5 can be arranged on the outside of the storage area to reduce the number of openings on the walls of the storage area. While improving the airtightness in the storage area, it is convenient to inspect and repair the cross pipe 31, the distribution pipe 32 and the feed port. The electrical drive component of the annular feed pipeline 5 is located on the outside of the storage area, which can further reduce the risk of dust explosion.

[0059] In addition, a filter is installed at the feed end of the annular feed pipeline 5. The filter belongs to the prior art and will not be described in detail in this application. The filter is used to filter the straw mixed in the bulk grain, thereby improving the purity of the grain stored inside the storage area and further preventing the bulk grain from being blocked inside the annular feed pipeline 5.

[0060] The bulk grain conveying system also includes a discharge mechanism 8 for conveying bulk grain in the storage area to the outside. The discharge mechanism 8 includes a discharge pipe 82 and an annular discharge pipeline 81 distributed at the bottom of different storage areas. The annular discharge pipeline 81 adopts the same structure as the annular feed pipeline 5. The interior of the annular discharge pipeline 81 conveys bulk grain through a circulating conveyor 6. The feed port of the annular discharge pipeline 81 is set at the bottom of the storage area. The annular discharge pipeline 81 has only one discharge port 51, and the discharge port 51 on the annular discharge pipeline 81 is sealed and connected to the discharge pipe 82. When the discharge port 51 is closed, air can be prevented from entering the annular discharge pipeline 81 through the discharge port 51, thereby improving the air tightness in the building warehouse discharge process and enhancing the moisture-proof effect inside the storage area.

[0061] In the specific implementation process, in order to improve the dust reduction effect when leaving the warehouse, a dust suppressor 83 is installed at the end of the discharge pipe 82 to prevent dust diffusion. The dust suppressor 83 adopts the DSH dust suppression system. The DSH dust suppression system belongs to the existing technology and will not be described in detail in this application. The dust suppressor 83 can be used to suppress the bulk grain leaving the warehouse.

[0062] The implementation principle of this embodiment is as follows: during the process of bulk grain entering the warehouse, the bulk grain transport vehicle pours the bulk grain in the bucket into the interior of the dust collector 12, and the bulk grain after dust removal by the dust collector 12 falls into the interior of the feed pipe 11, and is transported to the lifting pipe 21 through the feed conveyor inside the feed pipe 11, and then the bulk grain is lifted upward to the interior of the transverse pipe 31 by the bucket elevator, and then the bulk grain is divided into each distribution pipe 32 by the distribution conveyor inside the transverse pipe 31, and the bulk grain is transported to the interior of the annular feed pipeline 5 through the distribution pipe 32, and the annular feed pipeline 5 circulates the bulk grain through the circulation conveyor 6, and when the bulk grain is transported to the vicinity of the discharge port 51, the gear 73 is driven to rotate by the motor, and the arc gate plate 71 is gradually opened through the meshing transmission of the gear 73 and the rack 72, and the discharge port 51 is gradually opened, and then the sealing cover 75 is gradually opened by the elastic control member 76, so that the bulk grain falls into the interior of the storage area through the discharge port 51 for storage; During the process of bulk grain being discharged from the warehouse, the bulk grain at the bottom of the storage area falls into the feed port of the annular discharge pipeline 81, and the annular discharge pipeline 81 drives the bulk grain to move from the feed port to the discharge port 51 through the circulating conveyor 6. When the bulk grain is transported to the discharge port 51, the discharge port 51 is opened by a motor, allowing the bulk grain to fall into the discharge pipe 82 and fall into the bucket of the bulk grain transport vehicle through the end of the discharge pipe 82.

[0063] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
