Description

Technical Field

[0001] This invention relates to the field of grain storage, and more specifically to a folding floor cage assembly and folding floor cage used in grain storage. Background Technology

[0002] There are three relatively mature technologies in China for achieving automated inbound and outbound operations in tall, flat warehouses.

[0003] 1. Using a grain suction machine; the advantage is that no modification to the storage facilities is required. The disadvantages are: first, the equipment purchase cost is relatively high, generally above 300,000 yuan; second, it consumes a lot of energy, with a power of 75kW for a 50T output, resulting in high operating costs and a significant impact on the power grid, requiring high power supply from the grain depot. If multiple warehouses and multiple varieties are operating simultaneously, even within the China Grain Reserves Corporation system, there are not many grain depots that can fully meet the power supply requirements; third, manual dismantling of the ground cage is still required, necessitating on-site manual operation; and fourth, it results in the idle waste of existing grain unloaders, conveyors, and other equipment.

[0004] 2. Using underground trenches; the advantages are that they completely achieve a level and unobstructed surface, allowing grain storage machinery to pass freely. The disadvantages are: firstly, the complex construction process leads to high construction costs, and it is generally used for newly built warehouse floors, and cannot solve the problem of unloading from existing tall, flat warehouses through renovation; secondly, moisture-proofing is difficult, and there are safety hazards in later management; thirdly, the ventilation uniformity is 20% lower than that of above-ground cages, ventilation time is longer, and energy consumption is increased.

[0005] 3. Horizontal ventilation is adopted. Its advantages include a flat, unobstructed grain storage floor achieved by installing fume traps on the warehouse walls, and the traps not needing to be removed during entry and exit. Disadvantages include: firstly, only negative pressure ventilation is possible, requiring the grain surface to be covered with a film, resulting in high costs and a large workload; secondly, the horizontal ventilation path spans the warehouse, leading to a long ventilation distance and relatively small ventilation volume, making ventilation and water removal impossible; thirdly, existing warehouses with single-sided ventilation ducts need to be modified, and openings in the walls will damage the warehouse structure and affect its safety; fourthly, negative pressure circulation requires a high degree of airtightness of the grain surface, otherwise insufficient local phosphine concentration will result in incomplete fumigation; and fifthly, adopting horizontal ventilation changes the ventilation path, making nitrogen storage technology unsuitable.

[0006] In addition, the ground cage ventilation system is an important infrastructure for the ground ventilation system of grain warehouses. A search revealed that utility model application CN202222151225.X discloses a grain warehouse ventilation ground cage, including an inverted U-shaped main ground cage. A branch ground cage is snapped onto the bottom of the main ground cage along its extension direction. Bridge-shaped holes are provided on the outer curved surfaces of both the main and branch ground cages. Through holes are provided around the perimeter of the main ground cage, and threaded rods are installed in adjacent through holes at both ends of the main ground cage. Nuts are threaded to the two ends of the threaded rods extending outside the main ground cage. The radius of curvature of the branch ground cage is less than half that of the main ground cage. The nuts secure the threaded rods in the through holes at both ends of the main ground cage, thereby enhancing the overall structural strength of the main ground cage and preventing excessive pressure from the grain, which could lead to collapse and deformation. This type of ground cage is used for ventilation in grain warehouses, but it cannot be folded.

[0007] In addition, although the above-mentioned technical means have solved the impact of the ground cage on the entry and exit of the warehouse to a certain extent and realized the continuous operation of grain leaving the warehouse, their drawbacks are also very obvious. There are many restrictions in use, and they are not worth promoting on a large scale at the same time in large central grain reserve warehouses and small local grain reserve enterprises. Since various mechanical equipment need to move freely in the grain warehouse, the existing solutions are difficult to meet the needs of automated leaving equipment to operate without obstacles in the warehouse. Summary of the Invention

[0008] Therefore, in order to overcome the above-mentioned shortcomings, the present invention provides a folding ground cage assembly and a folding ground cage; this patent aims to solve the difficulty of grain removal from grain warehouses. By applying the folding ground cage, the ground cage can be laid flat during the removal process, enabling automated removal equipment to operate without obstacles in the warehouse, improving operational efficiency and enhancing the level of automation.

[0009] The present invention is implemented by constructing a folding floor cage assembly, characterized in that: the folding floor cage assembly has two arched plates, which are automatically tensioned by gravity, and the inner sides of the two arched plates are secured by inverted conical buckles to prevent them from automatically disengaging.

[0010] According to the present invention, a folding cage assembly is characterized in that: the tops of two arched plates are connected by a connecting shaft, and a pull rope is provided inside one of the arched plates. The pull rope is used to connect with a longitudinal pull rod to control the corresponding unlocking release device.

[0011] According to the present invention, a folding cage assembly is characterized in that: both arched plates have flip-up handles at the top, which facilitates quick connection during installation and convenient installation of pull ropes.

[0012] A folding ground cage, characterized in that: the folding ground cage has folding ground cage components and a release device; a straight section of the ground cage body is formed by combining multiple folding ground cage components; a transition section is connected to the straight section of the ground cage body according to the location of the ventilation opening and main ventilation duct of the ventilation system in the grain warehouse, that is, a triangular folding ground cage transition section is made at the interface of the main ventilation duct and the branch ventilation duct; and the tail end of the straight section of the ground cage body is sealed.

[0013] According to the present invention, a folding cage is characterized in that: the release device has a release block, one end of which is movably mounted on the inner wall of an arch plate by bolts; a longitudinal tie rod is arranged on the arch plate, and a locking block is provided on the longitudinal tie rod; a locking groove is opened at the upper end of the release block, and a protrusion below the locking block corresponds to the locking groove; it also has a release connecting block, one end of which is rotatably connected to a positioning block provided on the inner wall of the arch plate by bolts; a locking hook is provided at the lower end of the release connecting block, and a through slot is opened at the lower end of the release connecting block; the other end of the release block can be placed in the through slot to achieve overall positioning of the release connecting block; it also has a transverse tie rod, the upper end of which can be movably locked at the locking hook; the lower end of the transverse tie rod has an inverted cone, which can hook onto the inner wall of another arch plate.

[0014] According to the present invention, a folding floor cage is characterized in that, when the folding floor cage release mechanism is implemented, a positioning rod is also provided on the inner wall of the arch plate, and a locking block is inserted on the positioning rod.

[0015] According to the present invention, a folding floor cage is characterized in that: the straight section of the main body of the floor cage is divided into a first straight section and a middle straight section, and all the straight sections can be laid flat at once; wherein the first straight section is responsible for connecting to an external remote controller, receiving the flattening force transmitted from the outside and transmitting the flattening force down;

[0016] The arch plate is equipped with longitudinal tie rods, which are connected to the tie ropes. The two are connected by a female and a male butt joint.

[0017] The arch plate is equipped with a disassembly door, which allows for quick disconnection of the longitudinal tie rod during disassembly. The remote controller allows personnel to control the extension state of the ground cage from outside the warehouse. The remote controller is connected to the longitudinal tie rod via a pull rope. By operating the remote controller to touch the release mechanism inside the ground cage, the connection state inside the ground cage is changed, and the ground cage is flattened due to the pressure above the grain pile.

[0018] The function of the disassembly door is to facilitate manual connection of the screw during installation, ensuring the consistency of the actions of multiple sets of ground cages; the function of the connecting shaft is to transmit the action and ensure the consistency of the release action.

[0019] This application utilizes a folding grate cage, which can be laid flat during the grain silo release process.

The folding grate cage is well-suited for use in grain silos. Because it can be laid flat and folded, it allows various types of machinery to move freely within the silo. Its simple and stable structure is resistant to pressure and deformation, making it less prone to damage. It requires no grounding or major modifications to existing facilities, allowing existing grain machinery to continue operating. This results in lower investment costs and avoids waste, making it a popular choice.

This design largely solves the problem of flat ground in the grain silo, ensuring free movement of various types of machinery within the silo.

[0035] In this application, the tops of the two arched plates 1 are connected by a connecting shaft 6. A pull rope 4 can be installed inside one of the arched plates. The pull rope 4 is connected to the longitudinal pull rod 9 to control the corresponding unlocking mechanism, that is, to control the corresponding release device of this application. The connecting shafts 6 can be connected together between adjacent folding cage assemblies 10.

[0036] This application also includes flip-up handles 3 installed on the top of the two arched panels 1. The arched panels are lifted using the handles 3, facilitating quick connection with the adjacent folding floor cage assembly 10 during installation. The handles 3 also facilitate changing the folding floor cage assembly 10 from a flat state to a folded state (i.e.,...). Figure 3 The flattened state shown has been transformed into Figure 4 (The folded state is shown).

[0037] The present invention also provides a folding floor cage based on the above-described folding floor cage assembly 10, wherein the folding floor cage is a constituent of Figures 6-10The diagram shows the overall structure; the folding cage has multiple folding cage components 10 and a release device; it should be noted that the multiple folding cage components 10 are combined to form a straight section of the cage body, and according to the location of the ventilation openings and main ventilation ducts of the ventilation system in the grain warehouse, a transition section is connected to the straight section of the cage body, that is, a triangular folding cage transition section is made at the interface between the main ventilation duct and the branch ventilation duct, and the tail end of the straight section of the cage body is sealed.

[0038] like Figure 14 As shown, the release device has a release block 7. One end of the release block 7 is movably mounted on the inner wall of the arch plate A1 by bolts. A longitudinal tie rod 9 is arranged on the arch plate A1. A locking block 16 is provided on the longitudinal tie rod 9. A locking groove 17 is opened at the upper end of the release block 7. The protrusion 18 below the locking block 16 corresponds to the locking groove 17.

[0039] It also has a tripping connecting block 19. One end of the tripping connecting block 19 is connected to the positioning block 20 set on the inner wall of the arch plate A1 by bolts. The lower end of the tripping connecting block 19 has a latch hook 21 and a through slot 22. The other end of the release block 7 can be placed in the through slot 22 to achieve the overall positioning of the tripping connecting block 19.

[0040] It also has a horizontal tie rod 8, the upper end of which can be movably locked at the buckle hook 21, and the lower end of the horizontal tie rod 8 has an inverted cone 2, which can hook onto the inner wall of the arch plate B1.

[0041] When the folding cage release mechanism is implemented, a positioning rod 23 is also provided on the inner wall of the arch plate A1, and the locking block 16 passes through the positioning rod 23.

[0042] In this application, the straight section of the main body of the ground cage is divided into a first straight section and a middle straight section, and the straight section can be laid flat in one go; wherein the first straight section can be connected to an external remote controller, the remote controller can control the pull rope, connect to the leveling force transmitted from the outside and transmit the leveling force down.

[0043] A longitudinal tie rod 9 is installed inside the arch plate. The longitudinal tie rod 9 is connected to the pull rope 4. The two are connected by a female connector 12 and a male connector 14.

[0044] During disassembly, the connection at the longitudinal tie rod 9 can be quickly disconnected by disassembling door 5;

[0045] The remote controller allows personnel to control the extension state of the grain cage from outside the storage area. The remote controller is connected and controlled by a pull rope 4 and a longitudinal pull rod 9. By operating the remote controller to activate the release mechanism inside the grain cage, the connection state inside the cage is changed, and the grain cage is flattened due to the pressure above the grain pile. Figure 4 State change Figure 3 state.

[0046] The disassembly door 5 in this application also has the following functions, such as facilitating manual connection of the screw during installation, and ensuring the consistency of multiple sets of ground cage actions after the adjacent pull rods 9 are properly connected; the function of the connecting shaft 6 is to transmit actions and ensure the consistency of release actions.

[0047] The longitudinal tie rod 9 is connected to the pull rope via a male-female connector, and can be driven to move under the action of external force on the pull rope (i.e., Figure 14 The longitudinal pull rod 9 moves from left to right, which drives the release block 7 to disengage from the slot 22. After the release block 7 disengages, the transverse pull rod 8 will release, causing the inverted cone 2 corresponding to the transverse pull rod 8 to disengage from the inner wall of the arch plate B1. Then the arch plate is released, realizing the transformation from the folded state to the flat state. Figure 4 The state shown has changed to Figure 3 As shown in the diagram. When it is necessary to change from the flat state to the folded state, hook the inverted cone 2 onto the inner wall of the other arch plate.

[0064] Application Market Prospect Analysis: Currently, my country has nearly a thousand central grain reserves and over ten thousand local grain reserves of various types. The National Food and Strategic Reserves Administration, in its "Six Major Improvement Actions" plan for the High-Quality Grain Project, has clearly defined the development direction for improving the efficiency, mechanization, and intelligence of grain storage equipment. Ventilation cages, as essential infrastructure for grain ventilation, traditionally severely affect the continuity of equipment operation during grain removal, resulting in low operational efficiency. Using the folding cage developed in this project, the removal equipment can operate continuously within the storage facility without manual assistance.

[0065] In terms of operational efficiency, using foldable feed cages effectively avoids equipment downtime during cage removal, increasing outbound processing efficiency by over 30%. Regarding labor reduction, foldable feed cages eliminate the need for manual removal, reducing labor input by one man-day per 200 tons. In terms of energy conservation, they save 40 kWh per 200 tons of standby energy consumed during cage removal. Regarding improved working environment, they prevent occupational health problems caused by personnel removing feed cages in high-dust environments. In terms of intelligent operation, they provide the foundation for fully automated, unmanned operation of the outbound processing line. In summary, foldable feed cages make significant contributions to the economic and social benefits of grain rotation and have broad application prospects.
