Description

Technical Field

[0001] This invention relates to the field of grain storage engineering technology, specifically to a material transportation device and its usage method within an elevated shallow circular silo. Background Technology

[0002] In the grain storage industry, shallow circular silos are widely used in national grain reserves and large-scale grain processing enterprises due to their advantages of large storage capacity and small footprint. However, traditional shallow circular silos have long faced multiple technical bottlenecks in grain transportation, storage, and quality assurance, seriously affecting grain storage safety and transportation efficiency.

[0003] During storage, grain piles inside shallow circular silos are prone to automatic grading due to falling inertia. Impurities and broken grains concentrate in the central area, leading to poor ventilation and creating localized heating dead zones. Traditional temperature monitoring devices struggle to cover critical areas within the silo, making it difficult to detect heating and mold growth in the central region in a timely manner. By the time it is discovered, large-scale grain quality deterioration has already occurred. Simultaneously, temperature differences between the inside and outside of the silo easily cause condensation on the walls and roof, allowing moisture to penetrate the grain pile and cause localized dampness, further exacerbating grain quality deterioration. Static grain piles are prone to compaction, especially in high-humidity environments. Compacted grain piles not only affect subsequent unloading efficiency but also hinder the effective implementation of storage techniques such as ventilation and fumigation. Summary of the Invention

[0027] The method of using the material transport device inside the elevated shallow circular silo includes the following steps:

[0028] S1. Equipment preparation: According to the type of grain to be stored, adjust the overlap of the first mesh and the second mesh through the mesh adjustment mechanism to set a suitable ventilation sieve aperture; install the mesh cover assembly containing desiccant on the sealing cover of the feed pipe.

[0029] S2. Feeding and Storage: Open the sealing cover and inject grain into the main body of the grain silo through the feeding pipe; after feeding is completed, close the sealing cover, and the desiccant will perform preliminary dehumidification on the incoming air; start the stirring assembly to work periodically to prevent the grain from caking.

[0030] S3. Environmental control: The humidity sensor monitors the humidity inside the chamber in real time. When the humidity exceeds the set threshold, the controller starts the drying component. The air intake component sends the dehumidified and pressure-regulated air into the chamber through the ring pipe and nozzle. At the same time, the stirring component can work together to promote the uniformity of ventilation.

[0031] S4. Discharge and Transportation: When discharge is required, the discharge pipe channel is opened and the material conveying mechanism is started; the second drive motor synchronously drives the cross-shaped discharge piece to rotate and the second spiral blade to rotate and convey the grain through the conveying cylinder from the discharge pipe; the capacitive sensor monitors the material level and provides feedback to control the feeding or discharging process.

[0032] S5. Zoning Management: During storage or ventilation, the electric push rods of the baffle assembly can be extended as needed to drive the baffle to partially block the annular groove, thereby enabling independent control of ventilation or screening in specific areas of the grain pile.

[0033] Compared with the prior art, the beneficial effects of the present invention are:

[0034] 1. Through the collaborative design of the feeding component and the mesh cover component, impurities are pre-filtered before the grain enters the warehouse. It is detachable and adaptable to the filtration needs of different types of grain, effectively reducing the problem of clogging of the feeding pipe caused by large particles such as straw and stones. At the same time, the threaded sealing cover can prevent grain from splashing and external moisture from entering the warehouse. Combined with the dynamic ventilation adjustment of the mesh adjustment mechanism, the grain storage environment is improved from the source.

[0035] 2. With the help of sensor detection mechanism to comprehensively monitor the temperature and humidity of the grain pile in the warehouse, combined with the uniform air distribution design of the annular pipe and nozzle of the drying component, it can accurately locate local heat and dampness areas and implement targeted dehumidification, which solves the problems of uneven ventilation and unbalanced heat distribution in traditional storage. At the same time, the stirring component can break up the grain pile caking phenomenon, avoid the concentration of impurities and ventilation dead corners caused by automatic grading, and significantly improve the stability of grain quality.

[0036] 3. The mesh adjustment mechanism, drying components, and baffle components are integrated into the annular trough, resulting in a compact structure and coordinated functions. The baffle components can seal the annular trough when not in operation to prevent grain leakage and impurity accumulation. The mesh adjustment mechanism drives the mesh to rotate through the gear disk component, flexibly adjusting the air permeability to adapt to the needs of different storage stages. Combined with the stable conveying of the material transfer mechanism, it achieves efficient linkage of the entire process of entering, storing, and exiting the warehouse, greatly reducing the risk of operation interruption and manual maintenance costs.

[0037] 4. The main body of the grain silo is elevated by a support frame, which not only ensures the installation space and operational safety of the material conveying mechanism, but also reduces the erosion of the silo by ground moisture. Combined with the linkage control of the sensing and detection mechanism and various functional components, it can respond to changes in the state of the grain pile in real time and realize intelligent control of storage operations. Compared with the decentralized equipment layout of traditional shallow round silos, the overall operating efficiency and grain storage safety guarantee capability are significantly improved.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Example 1

[0046] Please see Figures 1-5 An elevated shallow circular silo material transport device includes:

[0047] The grain silo body 1 has a support frame 2 at its bottom. A stirring assembly is installed on the grain silo body 1. A sensing and detection mechanism is installed inside the grain silo body 1. The sensing and detection mechanism includes a capacitive sensor 13 and a humidity sensor 14. The capacitive sensor 13 is installed at the lower end of the inner cavity of the grain silo body 1, and the humidity sensor 14 is installed on the inner wall of the grain silo body 1.

[0048] The feeding assembly is located on the upper part of the grain silo body 1 and includes a feeding pipe 3 and a sealing cover 4 threaded to the end of the feeding pipe 3. The sealing cover 4 is equipped with a detachable mesh cover assembly, which includes: a mesh cover body 28, which contains a replaceable desiccant 29; a first engaging structure, including an L-shaped plate 30 on the sealing cover 4 and a first engaging groove 31 on the L-shaped plate 30, with a first engaging block 32 on one side of the mesh cover that engages with the first engaging groove 31; and a second engaging structure, including a connecting groove 33 on the sealing cover 4, a return spring 34 installed in the connecting groove 33, a moving plate 35 connected to the return spring 34, a lever 36 on the end of the moving plate 35, and a second engaging block 37, with a second engaging groove 38 on the other end of the mesh cover that engages with the second engaging block 37.

[0049] During the preparation for silo entry, the lever 36 of the second locking structure pushes the moving plate 35 to compress the return spring 34, and the first locking block 32 of the mesh cover body 28 is locked into the first locking groove 31 of the L-shaped plate 30. After the lever 36 is released, the return spring 34 drives the second locking block 37 to be embedded into the second locking groove 38, completing the detachable assembly of the mesh cover assembly and the sealing cover 4. The mesh cover body 28 with a suitable mesh size can be selected according to the type of grain and a desiccant 29 can be built in. During the feeding stage, the sealing cover 4 is opened and the grain enters the grain silo body 1 through the feeding pipe 3.

[0050] A stirring assembly is used to stir stored grain. The stirring assembly includes a first drive motor 10, a first rotating rod 11, and a first spiral blade 12. The first rotating rod 11 is rotatably connected to the grain silo body 1. The first spiral blade 12 is disposed on the first rotating rod 11. The first drive motor 10 is mounted on the grain silo body 1, and the output end of the first drive motor 10 is connected to the extension end of the first rotating rod 11 that passes through the grain silo body 1.

[0051] The material conveying mechanism is set at the lower end of the grain silo body 1 for grain transportation. The material conveying mechanism includes a feeding pipe 20 connected to the lower end of the grain silo body 1, a conveying cylinder 21 connected to the feeding pipe 20, and a spiral conveying component set in the conveying cylinder 21. A cross-shaped feeding component 23 is rotatably connected to the feeding pipe 20 through a connecting rod 22.

[0052] The conveying cylinder 21 is provided with a second rotating rod 24 and a second spiral blade 25 disposed on the second rotating rod 24. The end of the conveying cylinder 21 away from the discharge pipe 20 is provided with a discharge pipe 26, and an electric control valve 27 is installed on the discharge pipe 26. The second drive motor 45 drives the connecting rod 22 and the second rotating rod 24 simultaneously through the belt drive assembly.

[0053] When transporting materials from the elevated shallow circular silo, the controller 44 starts the second drive motor 45, which synchronously drives the connecting rod 22 and the second rotating rod 24 to rotate via the belt drive assembly. This transmission design enables the cross-shaped feeding component 23 and the second spiral blade 25 to achieve coaxial linkage: the cross-shaped feeding component 23 rotates with the connecting rod 22, breaking the blockage at the bottom of the grain pile and guiding the grain pile to enter the conveying cylinder 21 evenly. The second spiral blade 25 drives the grain to move towards the discharge pipe 26 through the spiral propulsion force. The controller 44 controls the opening of the electric control valve 27 to adjust the discharge speed according to the needs.

[0054] Before leaving the warehouse, the synergistic effect of mixing and conveying further improves operational efficiency: the controller 44 activates the mixing component to break up the compacted grain pile, while simultaneously adjusting the mesh adjustment mechanism to increase air permeability, and working with the drying component for short-term dehumidification, laying the foundation for smooth material feeding. Subsequently, the material conveying mechanism is activated, with the cross-shaped feeding component 23 linked to the lower end of the mixing component to ensure uniform feeding of the grain pile and prevent blockage of the conveying cylinder 21. After transportation is completed, the controller 44 shuts down all drive mechanisms, and the electric push rod 42 extends to drive the annular baffle 43 to block the annular groove 5, completing the closed-loop operation.

[0055] By adopting a structure that "synchronously drives the cross-shaped feeding component 23 and the second spiral blade 25 with a belt drive assembly," coaxial linkage between feeding and transmission is achieved. Combined with the pre-dispersing effect of the mixing assembly, this solves the problems of uneven feeding, easy clogging, and poor operational continuity of traditional transmission mechanisms, significantly improving the efficiency of grain silo transportation. At the same time, the overhead support frame 2 at the bottom of the grain silo body 1 reduces the impact of ground moisture on grain storage and optimizes the installation space and operational safety of the material transmission mechanism. Combined with the integrated design of multiple components inside the silo, it achieves the dual effect of moisture protection for the silo body and integrated installation of equipment, solving the problems of traditional shallow circular silos being susceptible to ground moisture erosion, having a cluttered equipment layout, and high operational risks.

[0056] The mesh adjustment mechanism is set in the annular groove 5 opened at the upper and lower ends of the grain silo body 1. It includes a first mesh 6, a second mesh 7 rotatably connected in the annular groove 5, and a gear disk assembly for driving the second mesh 7 to rotate. The gear disk assembly of the mesh adjustment mechanism includes: a third drive motor 39, which is installed in the annular groove 5; and a gear disk 40, which is connected to the output end of the motor and meshes with the lower tooth edge 41 of the second mesh 7, for adjusting the overlapping mesh size of the first mesh 6 and the second mesh 7.

[0057] The drying assembly includes an annular pipe 8 installed in the annular groove 5 and several nozzles 9 installed on the annular pipe 8. The annular pipe 8 is connected to an air intake assembly, which includes an adsorption rotary dehumidifier 15, a variable frequency centrifugal fan 16 and a connecting pipe 17 connected to the annular pipe 8. The adsorption rotary dehumidifier 15 and the variable frequency centrifugal fan 16 are installed on the grain silo body 1 and are connected. The connecting pipe 17 is equipped with a check valve 18 and a pressure sensor 19.

[0058] A baffle assembly is installed in the annular groove 5 to block the annular groove 5. The baffle assembly includes four electric push rods 42 and an annular baffle 43. The four electric push rods 42 are installed in the annular groove 5, and the output ends of the four electric push rods 42 are connected to the annular baffle 43.

[0059] During storage, the capacitive sensor 13 monitors the stacking status and compaction of the grain pile at the lower end of the grain silo body 1 in real time by sensing the change in the dielectric constant of the grain pile, while the humidity sensor 14 collects the humidity data of the air inside the silo in real time. The data from both sensors are transmitted synchronously to the controller 44, providing a precise basis for intelligent regulation. This sensing and detection principle ensures the comprehensiveness and timeliness of grain storage status monitoring.

[0060] Based on monitoring data, the controller 44 activates the stirring assembly, mesh adjustment mechanism, and drying assembly in a coordinated manner to achieve dynamic control of the grain pile: The stirring assembly is activated by the controller 44, which starts the first drive motor 10, driving the first rotating rod 11 and the first spiral blade 12 to rotate. The spiral blades tumble the grain pile in the silo, breaking up the grain pile compaction and dispersing impurities and broken grains concentrated due to automatic grading; The mesh adjustment mechanism is activated by the controller 44, which starts the third drive motor 39, driving the gear disk 40 to rotate. The gear disk 40 meshes with the lower tooth edge 41 of the second partition 7, driving the second partition 7 to rotate relative to the first partition 6. By adjusting the overlap of the meshes of the two partitions, the air permeability is dynamically adjusted; The drying assembly dehumidifies the air through the adsorption-type rotary dehumidifier 15, and the variable frequency centrifugal fan 16 delivers the dry air to the annular pipe 8 through the connecting pipe 17, and sprays it evenly onto the grain pile in the silo through several nozzles 9. The pressure sensor 19 monitors the air pressure in the connecting pipe 17 in real time, and the check valve 18 prevents air backflow, ensuring that the drying airflow is stable and controllable.

[0061] In this process, multiple components work together efficiently: the sensing-control coordination enables the controller 44 to automatically adjust the speed of the first drive motor 10, the direction of the third drive motor 39, and the wind speed of the variable frequency centrifugal fan 16 according to the degree of grain compaction and humidity exceeding the standard, so as to achieve dynamic response to the grain storage status; the drying-mesh adjustment coordination allows the controller 44 to adjust the mesh opening through the gear disk 40 component according to the data of the humidity sensor 14. When the humidity is high, the mesh is enlarged to improve the airflow penetration efficiency. When the humidity reaches the standard, the mesh is reduced to maintain stable temperature and humidity and avoid excessive ventilation that causes the grain to lose moisture. Thanks to the adoption of an intelligent control structure consisting of "capacitive sensor 13 + humidity sensor 14 + controller 44 + multi-component linkage," real-time monitoring of grain storage status and precise coordination of stirring, drying, and mesh adjustment are achieved. This solves the problems of lagging temperature and humidity monitoring, decentralized control of various equipment, and inability to dynamically adapt to grain storage needs in traditional warehousing, significantly improving the stability of grain quality. At the same time, the "gear disk 40 driven double mesh structure" enables stepless adjustment of mesh size. Combined with the uniform air distribution design of the drying components, it solves the problems of non-adjustable air permeability and uneven airflow distribution in traditional fixed meshes, ensuring uniform ventilation and dehumidification in different areas of the grain pile within the warehouse. The drying air intake structure consisting of "adsorption rotary dehumidifier 15 + pressure sensor 19 + check valve 18" ensures stable delivery and controllable pressure of dry air, solving the problems of unstable airflow, uneven dehumidification, and localized damping in traditional drying devices, and avoiding secondary damping caused by air backflow.

[0062] Furthermore, the baffle assembly, mesh adjustment mechanism, and drying component are integrated within the annular groove 5. The extension and retraction of the annular baffle 43 driven by the electric push rod 42 are synchronized with the start and stop states of each functional component, forming a protective-functional component synergy. This not only ensures the operating space of the mechanism during operation but also achieves sealed protection when not in operation, extending the service life of the components. Due to the compact design of "annular groove 5 integrating baffle assembly, mesh adjustment mechanism, and drying component," and the coordinated action of the baffle and functional components achieved through the electric push rod 42, the dual effects of structural integration and intelligent protection are realized. This solves the problems of traditional warehousing equipment being scattered, occupying large space, and having poor protection, reducing equipment maintenance costs and warehousing space occupancy.

[0063] In the above embodiment, a controller 44 is installed on the feed pipe 20. The controller 44 is electrically connected to the first drive motor 10, the capacitive sensor 13, the humidity sensor 14, the adsorption rotary dehumidifier 15, the variable frequency centrifugal fan 16, the check valve 18, the electric control valve 27, the pressure sensor 19, the second drive motor 45, the third drive motor 39, and the electric push rod 42.

[0064] It should be noted that the specific models and specifications of the controller 44, the first drive motor 10, the capacitive sensor 13, the humidity sensor 14, the adsorption-type rotary dehumidifier 15, the variable frequency centrifugal fan 16, the check valve 18, the electric control valve 27, the pressure sensor 19, the second drive motor 45, the third drive motor 39, and the electric push rod 42 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0069] S3. Environmental control: Humidity sensor 14 monitors the humidity in the chamber in real time. When the humidity exceeds the set threshold, controller 44 starts the drying component. The air intake component sends the dehumidified and pressure-regulated air into the chamber through the ring pipe 8 and nozzle 9. At the same time, the stirring component can work together to promote the uniformity of ventilation.
