Description

Technical Field

[0001] The present invention relates to the technical field of agricultural equipment, and in particular to a grain storage warehouse. Background Art

[0002] In the development of the grain storage industry, ensuring grain storage quality and improving storage efficiency have always been core pursuits. In existing technologies, grain is transported to storage warehouses for storage and then processed with supporting ventilation and drying facilities to extend the shelf life of the grain.

[0003] Traditional granaries generally use a top-feed method to load grain into the silo. This method has several drawbacks: due to differences in grain shape, maturity, and impurity types, components with similar properties tend to aggregate in the same area under the influence of gravity, leading to severe automatic grading. This not only results in uneven distribution of grain quality across the grain pile, but also creates a convex shape on the grain surface, with a high center and lower edges. This uneven grain surface significantly reduces the effective storage capacity of the silo and reduces storage space utilization. Furthermore, this uneven grain distribution causes uneven stress on the silo, which can damage the silo structure over time and shorten its service life.

[0004] To solve the problem of automatic grain grading and leveling, the existing technology has adopted a variety of equipment and methods, but all of them have obvious defects. Taking the threaded rod type distributor as an example, although it can achieve the flipping and ventilation of grain, promote the uniform falling of grain, and alleviate the automatic grading phenomenon to a certain extent, due to its complex structure and large size, it will take up a lot of space when installed and used in the warehouse, seriously compressing the available area of the warehouse, greatly increasing storage costs, and reducing storage efficiency. As for the mechanized fine grain leveling machine, although it can perform preliminary leveling of the grain surface, it still requires a lot of manual assistance and cannot achieve automated and efficient operation. Moreover, this equipment is only suitable for large grain silos, not for medium and small grain silos, and its application scenarios are greatly limited. There are also grain leveling robots based on machine vision, which are also more suitable for large grain silos. For small household grain silos, it is difficult to meet actual needs from the perspective of cost and applicability. Summary of the Invention

The discharging hopper has a structure that can be retracted in the up and down directions. The lifting mechanism supports the warehouse body on the ground and drives the warehouse body to move in the up and down directions. The warehouse body has a storage position close to the ground and a discharging position away from the ground in its moving stroke in the up and down directions.

[0020] The present invention provides a grain storage warehouse comprising a warehouse body, a warehouse cover assembly, and a blanking assembly. The warehouse body comprises a main body and a cover. The main body has an open cavity divided into a central area and a peripheral area. The inner and outer ring covers of the cover are spaced apart along the inner and outer rings, forming a first passage connecting the central area and a second passage connecting the peripheral area.

[0044] See also Figures 1 to 11The present invention provides a grain storage warehouse 1000, comprising a warehouse body 10, a warehouse cover assembly 20 and a blanking assembly 30. The warehouse body 10 comprises a main body 11 and a cover body 12, and a cavity 111 is provided in the main body 11. Generally speaking, the peripheral wall of the main body 11 is configured as a hollow structure, forming a ventilation cavity arranged around the periphery of the cavity 111. Specifically, the outer peripheral wall of the main body 11 can be configured in a rectangular shape for easy assembly, and the four corners of the inner peripheral wall are transitioned into arcs. The ventilation cavity between the four corners of the inner peripheral wall and the outer peripheral wall is connected to the cavity 111 through ventilation holes provided on the inner peripheral wall of the cavity 111. The storage equipment may further comprise a fan component for supplying air to the ventilation cavity. The fan component is detachably mounted on an external interface of the warehouse body 10, so that the ventilation cavity can be connected as needed to supply air to the cavity 111. In this way, the grain stored in the cavity 111 can be effectively dried, thereby extending the storage time of the grain. The fan can be selected as needed. For example, when drying grain, a hot air blower can be connected to the ventilation cavity, and when cooling grain, a cold air blower can be connected to the ventilation cavity. The external fan design allows the fan to be used across multiple grain storage warehouses 1000, providing high flexibility and helping to reduce grain storage costs.

[0045] Furthermore, if Figures 1 to 8 As shown, the upper end of the cavity 111 is provided with an opening 112, which has a central region 1121 and a peripheral region 1122 distributed around the central region 1121. The cover body 12 includes an inner ring cover 121 and an outer ring cover 122, which are arranged on the upper side of the opening 112. The inner ring cover 121 and the outer ring cover 122 are arranged in sequence along the inner and outer circles, thereby dividing the opening 112 into the central region 1121 and the peripheral region 1122. Furthermore, the inner ring cover 121 is provided with a first channel 123 extending vertically. The outer ring cover 122 and the inner ring cover 121 define a second channel 124 arranged around the periphery of the first channel 123. The lower end of the first channel 123 connects to the cavity 111 through the central region 1121, and the lower end of the second channel 124 connects to the cavity 111 through the peripheral region 1122.

[0046] The bin cover assembly 20 is mounted on the bin body 10 and includes a drive mechanism 21 and a movable cover 22. The movable cover 22 is horizontally movable relative to the bin body 10, with a first operating position in which the cover blocks the first passage 123 and a second operating position in which the cover opens the first passage 123. The drive mechanism 21 is drivably connected to the cover to reciprocate between the first and second operating positions, thereby periodically opening and closing the first passage 123 as needed.

[0047] The blanking assembly 30 is arranged above the silo body 10, and has various transmission modes. It has a blanking end 331 located directly above the first channel 123. The blanking assembly 30 is used to transport the material to be loaded into the silo to the blanking end 331, thereby delivering the material to be loaded into the cavity 111 from the opening 112.

[0048] In this embodiment, when the material-dropping assembly 30 is operating, it continuously delivers material directly above the first channel 123. Initially, the movable cover 22 is in the second operating position, and the first channel 123 is open. Material then falls from the central region 1121 into the chamber 111 through the first channel 123. As material continues to enter, when a predetermined amount is reached, the drive mechanism 21 is activated, driving the movable cover 22 to move to the first operating position. At this point, the first channel 123 is blocked, and the material, guided by the movable cover 22, disperses in all directions, finally falling from the peripheral region 1122 into the chamber 111 through the second channel 124. It will be appreciated that the operation of the drive mechanism 21 can be controlled by a control device, and its specific operating timing can be controlled by various control methods. For example, actual grain storage experience or sensors within the storage bin can be used to determine whether material has reached a predetermined amount by dropping from the first channel 123 into the chamber 111. Alternatively, a pre-set program can be used to determine whether the movable cover 22 has been in the second operating position for a predetermined period of time.

[0049] In this embodiment, when feeding grain, the blanking assembly 30 delivers the material to the discharge end 331, and the movable cover body 22 reciprocates between the first working position and the second working position to periodically open or close the first channel 123. When the movable cover body 22 is in the second working position, the material falls from the central area 1121 into the cavity 111 through this first channel 123. After a certain amount of material falls, the movable cover body 22 moves to the first working position, blocking the first channel 123, and the material falls from the outer area 1122 into the cavity 111 through the second channel 124. This alternating feeding method effectively improves the automatic grading problem of grain caused by the fixed landing point during traditional top feeding, ensures that the quality of grain in the grain pile is evenly distributed, the grain surface is smoother, and the effective storage capacity and space utilization of the granary are improved. It also makes the granary more evenly stressed and extends its service life. Compared with existing technologies, this feeding method has a simple structure and does not take up too much space, which reduces storage costs and improves storage efficiency. In addition, this feeding method has a high degree of automation and does not require too much manual assistance. It is suitable for granaries of various sizes and has a wider range of application scenarios.

[0050] In this embodiment, the movable cover 22 is driven by a drive mechanism 21 to move between a first working position and a second working position. The drive mechanism 21 can have various specific forms. Specifically, the drive mechanism 21 includes a track portion 211 and a drive portion 212. The track portion 211 is mounted on the upper end of the warehouse body 10 and includes a plurality of guide rails extending horizontally and arranged side by side. The movable cover is slidably mounted on the guide rails. The drive portion 212 includes a motor that is connected to the movable cover to drive the movable cover to slide along the guide rails. In actual application, the guide rails can be selected from high-precision linear guides to ensure the smoothness and accuracy of the movement of the movable cover 22. When the cover needs to be moved, the drive mechanism 21 drives the movable cover 22 to slide on the guide rails. When the first channel 123 needs to be opened, the motor drives the movable cover 22 to move to the second working position. When the first channel 123 needs to be blocked, the motor drives the movable cover 22 back to the first working position. This driving method has a simple structure and is easy to control. It can accurately control the position of the movable cover 22 to ensure that the first channel 123 is opened and closed accurately, thereby ensuring the smooth progress of the grain feeding process of the grain storage warehouse 1000 and improving the degree of automation and stability of grain feeding.

[0051] Based on the above examples, please refer to Figure 2 The second channel 124 extends downwardly from the inner circle to the outer circle. In this way, gravity is utilized to allow the material to slide more smoothly toward the outer circle into the cavity 111 when passing through the second channel 124, thereby preventing accumulation in the second channel 124.

[0052] Preferably, please continue to refer to Figure 6 and Figure 8 The inner and outer ring covers 121 and 122 are each conically cylindrical, with the inner cover 121 positioned below the outer cover 122 at intervals. The movable cover 22 overlies the inner cover 121 in its first operating position and lies on the periphery of the second passage 124 in its second operating position. The conical inner and outer ring covers 121 and 122 can be manufactured with a wear-resistant coating, such as a ceramic coating, to resist friction caused by grain passing through the passages, extending the service life of the inner and outer ring covers 121 and 122. This allows material to be more evenly distributed across the outer region 1122 of the chamber 111 when fed through the second passage 124, preventing it from becoming stuck in the second passage 124. This further improves grain surface flatness, reduces dead spots within the silo, and enhances the efficient use of storage space. This design ensures more even distribution of grain within the silo, further preventing automatic grading and effectively improving silo space utilization.

[0053] For details, please refer to Figure 6 and Figure 8The opening 112 is square in shape, and the outer periphery of the inner ring cover 121 is connected to the edge of the opening 112, thereby dividing the opening 112 into a central area 1121 and a peripheral area 1122. The peripheral area 1122 includes four corner areas spaced apart on the periphery of the central area 1121. In this embodiment, the square design of the warehouse body 10 can be customized according to different warehouse layouts and grain storage scales. Preferably, the four horizontal corners of the cavity 111 are rounded, that is, the four corners of the inner periphery of the cavity 111 are rounded. This increases the space in the peripheral area 1122, making material delivery smoother.

[0054] On the basis of the above-mentioned embodiment, the upper surface of the movable cover body 22 is provided with an arc surface with the center curved upward. In specific applications, the curvature of the arc surface can be optimized according to the size of the bin body 10 and the falling speed of the grain. Preferably, a wear-resistant coating, such as a ceramic coating, can be added to the surface of the arc surface to make the grain smoother when it is guided around through the arc surface, and to enhance the wear resistance of the movable cover body 22 and extend its service life. Preferably, some guide grooves can also be provided on the surface of the arc surface to further guide the flow direction of the grain, ensure that the grain can flow more evenly to the four corner areas, speed up the falling speed, and make the feed amount of the four corner areas more uniform.

[0055] Further, see Figure 9 and Figure 10 The grain storage warehouse 1000 also includes a discharging assembly 40, which includes a lifting mechanism 41 and a discharging hopper 42. The discharging hopper 42 is arranged at the lower end of the warehouse body 10 and is provided with a discharging door 422 connected to the cavity 111. The discharging hopper 42 has a retractable structure in the up and down directions. The lifting mechanism 41 supports the warehouse body 10 on the ground and drives the connected warehouse body 10 to drive the warehouse body 10 to move in the up and down directions. The warehouse body 10 has a storage position close to the ground and a discharging position far from the ground in its moving stroke in the up and down directions. When the warehouse body 10 is in the storage position, the discharging hopper 42 is compressed, and when the warehouse body 10 is in the discharging position, the discharging hopper 42 is extended.

[0056] In this embodiment, the specific type of the lifting mechanism 41 is not limited, as long as it can drive the silo 10 to rise and fall as needed. When there is no need to discharge, the discharge door 422 is closed, the discharge hopper 42 is compressed, and the silo 10 is in the storage position to store grain, thereby reducing the load on the lifting mechanism 41. When discharge is required, the lifting mechanism 41 drives the silo 10 to move up to the discharge position, so that a space is formed under the silo 10 that is convenient for the entry and exit of material transportation equipment. At this time, material transportation equipment such as a trolley can travel to the bottom of the silo 10, open the discharge door 422 automatically or manually, and the material in the cavity 111 can fall directly into the material transportation equipment under the action of gravity and be conveniently transported away. This discharge method is simple to operate and efficient. Compared with the traditional discharge method, no additional auxiliary equipment is required to transport the grain from the bottom of the silo, which reduces labor intensity and improves discharge efficiency. It also reduces the residue of grain during the discharge process and improves the utilization rate of grain.

[0057] Furthermore, the lifting mechanism 41 includes multiple hydraulic cylinders 411 and multiple hydraulic rods 412 extending from the upper ends of each hydraulic cylinder 411. Each hydraulic cylinder 411 is buried below the ground, and the upper ends of each hydraulic rod 412 are respectively connected and fixed to the silo 10. When the silo 10 is in the storage position, the silo 10 is seated on the ground via the discharge hopper 42. In this embodiment, the telescopic movement of the hydraulic cylinders 411 and hydraulic rods 412 is used to drive the silo 10 up and down, providing stable and reliable support for the silo 10. When the silo 10 is in the storage position, the ground supports the entire silo 10 and the telescopic discharge hopper 42 at the bottom. In other words, when the chamber 111 is fully loaded, the ground directly supports the weight of the materials and the silo 10 most of the time. This reduces the structural strength requirements for the silo 10 and the discharge hopper 42, reduces production costs, improves the reliability of the grain storage warehouse 1000, and extends its service life. When the cavity 111 is empty, a pad can be placed on the upper side of the discharge hopper 42, and the cavity 111 can be used to store other materials to improve the utilization rate of the grain storage warehouse 1000.

[0058] The structure of the discharge hopper 42 can be designed as needed. In this embodiment, please refer to Figure 10The discharge hopper 42 includes a plurality of discharge plates 421 and a plurality of flexible connectors 423. Each discharge plate 421 extends in a ring shape, and the plurality of discharge plates 421 are arranged in sequence along the inner and outer circles. The discharge door 422 can be installed on the discharge plate 421 of the innermost circle in an openable and closable manner. Each flexible connector 423 is connected one-to-one between each two adjacent discharge plates 421 of the inner and outer circles. In actual production, the discharge plate 421 can be made of wear-resistant metal materials, such as manganese steel, to increase the service life of the discharge plate 421. The flexible connector 423 can be made of rubber or high-strength flexible plastic to ensure that the discharge plates 421 can be effectively connected during the expansion and contraction of the discharge hopper 42, while having certain flexibility and corrosion resistance. When selecting the rubber material, nitrile rubber can be used, which has good oil resistance and wear resistance and can adapt to the friction and extrusion in the grain discharging process. When discharging is required, the bin body 10 rises to the discharging position, the discharging hopper 42 automatically extends, and the flexible connector 423 stretches as the discharging plate 421 unfolds, so that the discharging hopper 42 forms a complete discharging structure. When the discharging door 422 is opened, the grain flows out from the opening of the innermost discharging plate 421. Since the discharging plates 421 are annular and arranged in sequence, they can guide the grain to be discharged evenly from the discharging hopper 42, avoiding uneven discharging or blockage. The presence of the flexible connector 423 not only ensures the structural integrity of the discharging hopper 42 during the expansion and contraction process, but also can adapt to different degrees of expansion and contraction, thereby improving the reliability and practicality of the discharging hopper 42.

[0059] Based on the above embodiments, please refer to Figure 2 and Figure 11 The blanking assembly 30 includes a silo top box 31, a linear module 32 and a conveyor belt 33. The silo top box 31 is arranged above the silo body 10, and a blanking port 311 is opened on the lower side directly above the central area 1121. The linear module 32 is arranged in the silo top box 31 and extends in the horizontal direction. The conveyor belt 33 is slidably mounted on the linear module 32, and has a storage position with its front end located in the silo top and a transport position with its front end extending out of the silo top. When the conveyor belt 33 is in the transport position, the end of the conveyor belt 33 is located directly above the blanking port 311 to form a blanking end 331.

[0060] In this embodiment, when grain needs to be fed, the linear module 32 drives the conveyor belt 33 to move from the storage position to the transport position, so that the end of the conveyor belt 33 is located directly above the feeding port 311. At this time, the conveyor belt 33 is started to transport the grain to the feeding port 311, and then enters the warehouse body 10 through the first channel 123 or the second channel 124. When the grain feeding is completed, the linear module 32 drives the conveyor belt 33 back to the storage position to prevent the conveyor belt 33 from being exposed to the outdoors when not in operation and being damaged. The design of this feeding assembly 30 is flexible and convenient, and can accurately transport grain to the specified location, thereby improving the efficiency and accuracy of grain feeding.
