Description

Technical Field

[0001] This utility model relates to the field of grain storage equipment technology, specifically to a grain storage container equipped with a novel grain discharging device. Background Technology

[0002] Grain reserves are of great significance for ensuring food security, responding to risks, and protecting people's livelihoods. Traditional warehouse grain storage and handling are inefficient, and containerized grain storage is now widely used. Containerized grain storage and transportation has several advantages: first, it meets the needs of transporting various varieties of grain in small batches, as well as grains of different qualities and grades; second, it eliminates the need to build dedicated bulk grain distribution facilities, allowing full use of general-purpose container loading and unloading equipment and reducing basic construction investment; and third, the use of mechanized operations reduces labor intensity, environmental pollution, and overall transportation costs.

[0003] However, existing technologies present the following technical problems regarding how to unload (i.e., remove) grain from storage containers:

[0004] First, some existing technologies require opening the end doors of the grain storage containers for manual unloading. This results in low levels of automation and high labor intensity. Second, opening the doors could cause the accumulated grain to spill out instantly, leading to waste and potential accidents.

[0005] Secondly, some existing grain storage containers have unloading doors at the ends, requiring the entire container to be hoisted and tilted for unloading. This results in slow unloading speed and low efficiency, and also necessitates the use of specialized hoisting equipment, leading to high operating costs.

[0006] Third, existing grain storage containers all unload grain at the ends, and the wider and more spacious sides of the container are not well utilized, such as for docking with external conveyor belt mechanisms. Utility Model Content

[0007] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a grain storage container equipped with a new type of grain discharge device, which has a simple and compact structure, a high degree of intelligence and automation, safe and reliable unloading, high unloading efficiency, and strong operational adaptability.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] A grain storage container equipped with a novel grain discharging device includes a grain storage container with a grain discharging port on each of its two opposite side walls. A bidirectional grain pushing mechanism is provided between the two grain discharging ports inside the grain storage container. The bidirectional grain pushing mechanism includes a bidirectional drive component, a sprocket assembly, and multiple push plate assemblies arranged on the sprocket assembly. The bidirectional drive component drives the sprocket assembly to move the multiple push plate assemblies in both directions to push the grain out from either grain discharging port.

[0010] As a further improvement to the above technical solution:

[0011] The sprocket assembly includes a mounting frame and two turns of the first drive chain. The mounting frame is provided with a pair of driving wheels, a pair of driven wheels and multiple pairs of support wheels. The two turns of the first drive chain are respectively wound around the pair of driving wheels, the pair of driven wheels and the multiple pairs of support wheels. Each push plate assembly is simultaneously fixed on the two turns of the first drive chain.

[0012] The bidirectional drive assembly includes a bidirectional drive motor and a second transmission chain. A drive gear is provided on the drive shaft end of the bidirectional drive motor and on the rotation shaft of any drive wheel. The second transmission chain is wound around the two drive gears to drive the drive wheel to rotate in both directions via the bidirectional drive motor.

[0013] Each of the push plate assemblies includes two fixed plates and one push plate. Both fixed plates are simultaneously fixed to two turns of the first drive chain by screws. A clamping space is formed between the two fixed plates to allow for the detachable clamping and fixing of the push plate by screws.

[0014] Each of the push plates is made of rubber or silicone.

[0015] The bidirectional grain pushing mechanism includes a protective cover, which includes two side plates and a top plate to cover the bidirectional drive assembly, sprocket assembly and push plate assembly for protection. At least one side plate has a gap between its bottom and the bottom plate of the grain storage container to facilitate the rapid introduction of grain into the protective cover and its push plate assembly.

[0016] The protective cover also includes at least one guide plate, which is arranged at an angle above the top plate to quickly guide the grain above the protective cover to the lower spaced feed section.

[0017] A vibrator is also installed at the bottom of the guide plate.

[0018] The grain storage container has a grain inlet in the middle of its top surface, and the bidirectional grain pushing mechanism is located near either end of the grain storage container to prevent the grain injected in the middle from impacting the bidirectional grain pushing mechanism.

[0019] The grain inlet is equipped with a sealed top cover.

[0020] Compared with the prior art, the advantages of this utility model are:

[0021] Firstly, the grain storage container of this utility model is equipped with a new type of grain discharge device. It has a grain discharge port on both sides of the longitudinal direction and a bidirectional grain pushing mechanism that can discharge grain in both directions. This makes good use of the wider and more flexible side of the container. It can connect with the external transmission structure on either side or both sides at the same time, making it highly adaptable to operation.

[0022] Secondly, the grain storage container of this utility model, equipped with a novel grain discharge device, features a special bidirectional grain pushing mechanism that eliminates the need for manual unloading. This is characterized by its high degree of intelligence and automation, significantly reducing the intensity of manual labor. Furthermore, it prevents the possibility of accumulated grain spilling out instantly when the end cabinet doors are opened, greatly reducing waste and accidents, and ensuring safe and reliable unloading. Thirdly, it effectively solves the problems of slow unloading speed, low unloading efficiency, and high hoisting operation costs caused by lifting and tilting the entire grain storage container for unloading, resulting in high unloading efficiency.

[0023] Third, the grain storage container of this utility model with a novel grain discharge device has a pair of driving wheels, a pair of driven wheels and multiple pairs of support wheels that can simultaneously provide good support for the two first transmission chains, and thus provide good support for the multiple push plate assemblies installed on the two first transmission chains, resulting in strong driving force, safe and reliable grain unloading, and high grain unloading efficiency.

[0024] Fourth, the grain storage container of this utility model, equipped with a novel grain discharging device, features a clamping space between two fixed plates for detachably clamping and fixing the push plate using screws. This detachable design facilitates both manufacturing and installation, and allows for quick removal and replacement of worn push plates for maintenance. Each push plate is made of rubber or silicone. This gives the push plate a certain degree of elasticity and flexibility, significantly reducing damage to the grain.

[0025] Fifth, the grain storage container of this utility model equipped with a novel grain discharge device has a protective cover that serves several purposes: first, it protects the bidirectional drive assembly, sprocket assembly, and push plate assembly; second, it prevents grain from entering the sprocket assembly and causing blockages and malfunctions; and third, the spaced feeding section at the bottom allows the grain to be guided into the protective cover and pushed away by the push plate assembly, effectively ensuring efficient grain unloading.

[0026] Sixth, the grain storage container of this utility model equipped with a novel grain discharge device, by setting a guide plate on the top, firstly further reduces the impact of grain compression on the top, and secondly avoids the formation of residual grain on the top. Thirdly, an installation gap is formed between the guide plate and the top plate, which facilitates the installation of a vibrator at the bottom of the guide plate to quickly shake the grain off.

[0027] Seventh, the present invention provides a grain storage container equipped with a novel grain dispensing device. The grain storage container has a grain inlet in the middle of its top surface, and a bidirectional grain pushing mechanism is located near either end of the grain storage container to prevent the grain injected in the middle from impacting the bidirectional grain pushing mechanism, thus effectively extending the service life of the bidirectional grain pushing mechanism.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0038] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0039] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0040] like Figures 1 to 7 As shown, the grain storage container equipped with the novel grain dispensing device in this embodiment includes a grain storage container 1. Each of the two opposite side walls (i.e., the two side walls along the length) of the grain storage container 1 has a grain dispensing port 11. A bidirectional grain pushing mechanism 2 is provided inside the grain storage container 1 between the two grain dispensing ports 11. The bidirectional grain pushing mechanism 2 includes a bidirectional drive assembly 21, a sprocket assembly 22, and multiple pusher plate assemblies 23 arranged on the sprocket assembly 22. The bidirectional drive assembly 21 drives the sprocket assembly 22 to move the multiple pusher plate assemblies 23 in both directions to push the grain out from either grain dispensing port 11. The specific implementation principle is as follows:

[0041] This grain storage container, equipped with a novel grain discharge device, has a grain discharge port 11 on each of its two side walls along its length, and a bidirectional grain pushing mechanism 2 for bidirectional grain discharge. This allows for efficient use of the wider and more flexible side of the container, enabling docking with external transmission structures on either side or both sides simultaneously. If the current operation requires docking with the right-side transmission structure (or grain storage facility), the sealed door on the grain discharge port 11 on the right side wall of the grain storage container 1 is opened, and the bidirectional grain pushing mechanism 2 is activated to transport the grain in the right direction as shown in the diagram. At this time, the bidirectional drive assembly 21 drives the sprocket assembly 22 to rotate counterclockwise, which in turn drives multiple pusher plate assemblies 23 to move counterclockwise. The multiple pusher plate assemblies 23 move towards the right-side grain discharge port 11, quickly pushing the grain out of the right-side grain discharge port 11, achieving efficient right-side grain discharge and unloading.

[0042] When grain needs to be discharged from the left side, the sealed small door on the grain outlet 11 on the left side wall of the grain storage container 1 is opened, and the bidirectional grain pushing mechanism 2 is activated to move in the reverse direction. At this time, the bidirectional drive component 21 drives the sprocket assembly 22 to rotate clockwise, which in turn drives the multiple push plate assemblies 23 to move clockwise. The multiple push plate assemblies 23 move towards the grain outlet 11 on the left side, quickly pushing the grain out of the grain outlet 11 on the left side, achieving efficient grain discharge and unloading from the left side. Through the above special scientific design, it has the following technical advantages:

[0043] Firstly, the grain storage container of this utility model is equipped with a new type of grain discharge device. It has a grain discharge port 11 on both sides of the length direction and a bidirectional grain pushing mechanism 2 that can discharge grain in both directions. This makes good use of the wider and more flexible side of the container. It can connect with the external transmission structure on either side or both sides at the same time, and has strong operational adaptability.

[0044] Secondly, the grain storage container of this utility model, equipped with a novel grain discharge device, features a special bidirectional grain pushing mechanism 2, which eliminates the need for manual unloading. This is characterized by a high degree of intelligence and automation, significantly reducing the intensity of manual labor. Furthermore, it prevents the accumulation of grain from spilling out instantly when the end cabinet doors are opened, greatly reducing waste and accidents, and ensuring safe and reliable unloading. Thirdly, it effectively solves the problems of slow unloading speed, low unloading efficiency, and high hoisting operation costs caused by tilting the entire grain storage container for unloading, resulting in high unloading efficiency.

[0045] In this embodiment, the sprocket assembly 22 includes a mounting frame 221 and two turns of the first transmission chain 225. The mounting frame 221 is equipped with a pair of driving wheels 222, a pair of driven wheels 223, and multiple pairs of support wheels 224. The two turns of the first transmission chain 225 are respectively wound around the pair of driving wheels 222, the pair of driven wheels 223, and the multiple pairs of support wheels 224. Each push plate assembly 23 is simultaneously fixed on the two turns of the first transmission chain 225. The pair of driving wheels 222, the pair of driven wheels 223, and the multiple pairs of support wheels 224 can simultaneously provide good support for the two turns of the first transmission chain 225, thereby providing good support for the multiple push plate assemblies 23 mounted on the two turns of the first transmission chain 225, resulting in high driving force, safe and reliable grain unloading, and high grain unloading efficiency.

[0046] In this embodiment, the bidirectional drive assembly 21 includes a bidirectional drive motor 211 and a second transmission chain 212. A drive gear is provided on the drive shaft end of the bidirectional drive motor 211 and the rotation shaft of any drive wheel 222. The second transmission chain 212 is wound around the two drive gears to drive the drive wheel 222 to rotate in both directions via the bidirectional drive motor 211.

[0047] In this embodiment, each push plate assembly 23 includes two fixing plates 231 and one push plate 232. Both fixing plates 231 are simultaneously fixed to two turns of the first transmission chain 225 by screws. A clamping space is formed between the two fixing plates 231 to allow for the detachable clamping and fixing of the push plate 232 by screws. This detachable method facilitates manufacturing and installation, and also allows for the quick removal and replacement of worn push plates 232 for maintenance.

[0048] In this embodiment, each pusher plate 232 is made of rubber or silicone. This gives the pusher plate 232 a certain degree of elasticity and flexibility, greatly reducing damage to the grain.

[0049] In this embodiment, the bidirectional grain pushing mechanism 2 includes a protective cover 24. The protective cover 24 includes two side plates 241 and a top plate 242 to cover and protect the bidirectional drive assembly 21, the sprocket assembly 22, and the pusher plate assembly 23. At least one side plate 241 has a gap between its bottom and the bottom plate of the grain storage container 1 to facilitate the rapid introduction of grain into the protective cover 24, where it is pushed away by the pusher plate assembly 23. The protective cover 24 serves three purposes: first, it protects the bidirectional drive assembly 21, the sprocket assembly 22, and the pusher plate assembly 23; second, it prevents grain from entering the sprocket assembly 22 and causing blockage or malfunction; and third, the gap at the bottom allows grain to be introduced into the protective cover 24 and pushed away by the pusher plate assembly 23, effectively ensuring efficient grain unloading.

[0050] In this embodiment, the protective cover 24 also includes at least one guide plate 243, which is inclinedly arranged above the top plate 242 to quickly guide the grain above the protective cover 24 to the lower spaced feed section. Without the guide plate 243, residual grain may accumulate on the flat top plate 242. By providing a guide plate 243 at the top, firstly, the impact of grain compression at the top is further reduced; secondly, residual grain is avoided at the top; and thirdly, an installation gap is formed between the guide plate 243 and the top plate 242, facilitating the installation of a vibrator (not shown in the figure) at the bottom of the guide plate 243 to quickly shake the grain off.

[0051] It should be noted that if the bidirectional grain pushing mechanism 2 is located at either end of the grain storage container 1 as described below, only one guide plate 243 is needed. If the bidirectional grain pushing mechanism 2 is located in the middle of the grain storage container 1, two guide plates 243 are needed to form a pointed shape.

[0052] In this embodiment, a grain inlet is provided in the middle of the top surface of the grain storage container 1, and a bidirectional grain pushing mechanism 2 is provided near either end of the grain storage container 1 to prevent the grain injected in the middle from impacting the bidirectional grain pushing mechanism 2, thereby effectively extending the service life of the bidirectional grain pushing mechanism 2.

[0053] In this embodiment, a sealing top cover 12 is provided at the grain inlet.

[0054] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
