Description

Technical Field

[0001] This utility model relates to the field of grain warehouse ventilation technology, and in particular to a high-pressure-resistant ground ventilation cage for grain warehouses. Background Technology

[0002] The emergence of high-compression, ground-level ventilated cages for grain storage is primarily to address issues such as ventilation, heat dissipation, moisture control, and insect prevention during grain storage, thereby ensuring grain quality and safety. Grain is one of the basic resources for human survival, and its storage quality directly affects national food security and social stability. During storage, grain needs to be kept dry, ventilated, and at low temperatures to prevent mold, insect infestation, and sprouting.

[0003] During the installation of ventilation cages, the connections between components may require the use of traditional fasteners such as bolts and nuts for individual installation, a cumbersome process that consumes significant time and manpower. Similarly, disassembly, repair, or component replacement increases maintenance time costs. The overall size of the ventilation cage is large, occupying considerable space and increasing the difficulty of transportation and storage, thus reducing the flexibility and adaptability of the grain silo ventilation system. In daily grain silo operation, external forces may act on the ventilation cages, such as collisions during grain loading and unloading, and vibrations from other equipment within the silo. The lack of effective support on the internal top wall of the ventilation cage weakens its resistance to external impacts, making it more susceptible to damage. This can lead to inconsistent distances between the ventilation openings and the grain pile, resulting in uneven airflow distribution—some areas well-ventilated while others are poorly ventilated, affecting the storage quality of the grain and shortening its lifespan. Utility Model Content

[0004] The main purpose of this utility model is to provide a high-compression-resistant ground ventilation cage for grain warehouses, which can effectively solve the problems of increased maintenance time and costs, large overall volume of the ventilation cage, large space occupation, increased difficulty of transportation and storage, reduced flexibility and adaptability of grain warehouse ventilation system, and inconsistent distance between ventilation openings and grain piles, resulting in uneven airflow distribution, with some areas having good ventilation and others having insufficient ventilation, which affects the storage quality of grain and shortens its service life.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-pressure-resistant ground ventilation cage for grain storage, comprising a cage body, with semicircular rings fixedly connected to both the left and right sides of the cage body, and bottom plates fixedly connected to both the front and rear sides of the bottom wall of the cage body. Three mounting blocks are fixedly connected to the right side wall of each of the right semicircular rings, and two locking blocks are fixedly connected to the right side wall of each mounting block. Three outer shells are fixedly connected inside the left semicircular ring, and two support rods are slidably connected to both the front and rear sides of each outer shell.

[0006] Furthermore, each of the support rods has four first springs fixedly connected to its rear sidewall, and the other end of every eight first springs is fixedly connected to the front and rear sides of the interior of the housing.

[0007] Furthermore, each of the housings has two placement slots inside, and two second springs are fixedly connected inside each placement slot. The other ends of the two second springs are fixedly connected to baffles.

[0008] Furthermore, each of the card blocks is disposed inside a placement slot, and the slot of each card block is correspondingly disposed to the rear of a support rod.

[0009] Furthermore, protective boxes are fixedly connected to both sides of the inner top wall of the cage, and motors are installed inside the two protective boxes. Lead screws are fixedly connected to the output ends of the two motors.

[0010] Furthermore, the bottom ends of the two lead screws are fixedly connected to limit rings, and the outer sides of the two lead screws are slidably connected to internally threaded sleeves.

[0011] Furthermore, an outer cylinder is fixedly connected to the outer side of each of the two internally threaded sleeves, a base is fixedly connected to the bottom end of each of the two outer cylinders, and the two limiting rings are both disposed inside the two outer cylinders.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model, through its designed locking block, support rod, placement slot, and baffle, solves the problems of increased maintenance time and costs, large overall volume of the ventilation cage, significant space occupation, increased transportation and storage difficulties, and reduced flexibility and adaptability of the grain silo ventilation system. By pressing the support rod, the rear wall of the support rod compresses the first spring, causing the rear part of the support rod to retract into the outer shell and disengage from the slot of the locking block. After the support rod disengages, the locking block is no longer restricted by the support rod. At this time, the compressed second spring pushes the baffle, thereby pushing the locking block out of the placement slot. Installers only need to pull apart the ventilation cages to complete the separation operation of the two ventilation cages, thus effectively shortening the installation time, improving work efficiency, avoiding a complicated disassembly process, saving manpower and time, and extending its service life.

[0014] 2. By incorporating a motor, lead screw, outer cylinder, base, and limit ring, the system effectively addresses the problem of uneven airflow distribution caused by inconsistent distances between the ventilation openings and the grain pile. This results in well-ventilated areas but insufficient ventilation in others, impacting grain storage quality and shortening its lifespan. The lead screw and internal threaded sleeve are connected via a threaded connection. When the lead screw rotates, the internal threaded sleeve moves up and down along the axial direction of the lead screw due to the interaction of the threads. Since the internal threaded sleeve is fixedly connected to the outer cylinder, the outer cylinder rises and falls synchronously with the internal threaded sleeve. The bottom of the outer cylinder is connected to the base, which ultimately adjusts the internal support height of the ventilation cage. This effectively improves resistance to deformation, maintains the shape and structural integrity of the ventilation cage, ensures its normal function, and guarantees the continuous and effective operation of the ventilation system to meet the ventilation requirements during grain storage.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figure 1 - Figure 4 The image shows a high-compression-resistant, ground-level ventilation cage for grain storage, comprising a cage body 1. Semicircular rings 2 are fixedly connected to both the left and right sides of the cage body 1. These semicircular rings 2 provide support to the left and right sides of the cage body 1 to prevent external damage, and also facilitate the connection of multiple cage bodies 1. However, this can lead to compression of the internal ventilation holes of the cage body 1. Base plates 3 are fixedly connected to the front and rear sides of the bottom wall of the cage body 1. These base plates 3 provide bottom support for the device and prevent insects from entering the interior of the cage body 1 through the bottom.

[0028] Three mounting blocks 4 are fixedly connected to the right side wall of the right semicircular ring 2. Two locking blocks 5 are fixedly connected to the right side wall of each mounting block 4. The locking blocks 5 are connected by the mounting blocks 4 to fix the locking blocks 5 inside the right semicircular ring 2 and connect to the device inside the left semicircular ring 2 of the right cage body 1.

[0029] Three outer shells 6 are fixedly connected inside the left semi-circular ring 2. Two support rods 7 are slidably connected to the front and rear sides of each outer shell 6. Four first springs 8 are fixedly connected to the rear side wall of each support rod 7. The other end of each set of eight first springs 8 is fixedly connected to the front and rear sides inside the outer shell 6. The outer shells 6 are used to protect the internal parts from the outside. When the operator presses the support rods 7 on the front and rear sides of the outer shell 6, the support rods 7 slide inside the outer shell 6. When the support rods 7 slide inward, the rear side wall of the support rods 7 will squeeze the first springs 8, causing the first springs 8 to compress. At the same time, the rear part of the support rods 7 will slide from the placement groove 9 into the cage 1. When released, the first springs 8 will release pressure, causing the support rods 7 to spring back to their original position.

[0030] like Figure 1 - Figure 5As shown, each housing 6 has two placement slots 9 inside, and two second springs 10 are fixedly connected inside each placement slot 9. The other end of the two second springs 10 is fixedly connected to a baffle 11. Each locking block 5 is set inside a placement slot 9, and the hole slot of each locking block 5 is correspondingly set to the rear of a support rod 7.

[0031] As shown above, when the two cages 1 are connected, the locking block 5 on the left cage 1 is inserted into the placement slot 9 inside the left outer shell 6 of the right cage 1. Under the action of pushing, when the locking block 5 enters the placement slot 9, the right side wall of the locking block 5 will first contact the rear of the support rod 7. By pushing the locking block 5 into the placement slot 9, the right side wall of the locking block 5 will push the rear of the support rod 7 into the outer shell 6 to squeeze the first spring 8. When the locking block 5 breaks through the position of the support rod 7, the right side wall of the locking block 5 will contact the baffle 11 inside the placement slot 9 to push the baffle 11 to squeeze the second spring 10, thereby opening the interior of the placement slot 9. When the locking block 5 is fully inserted into the interior of the placement slot 9, the support rod 7 will rebound through the first spring 8, so that the rear of the support rod 7 is inserted into the hole slot of the locking block 5 to fix the locking block 5 inside the outer shell 6, thereby fixing the two cages 1 together.

[0032] In addition, when disassembly is required, the operator first presses the support rod 7 to slide inside the outer casing 6 and compresses the first spring 8, causing the rear part of the support rod 7 to retract into the outer casing 6, thus disengaging the rear part of the support rod 7 from the slot of the locking block 5. After the support rod 7 disengages from the locking block 5, the locking block 5 is no longer restricted by the support rod 7. At this time, the compressed second spring 10 pushes the baffle 11, thereby pushing the locking block 5 out of the placement slot 9. The installer only needs to pull open the ventilation cage to complete the separation operation of the two ventilation cages. In addition, by releasing the pressure of the second spring 10, the baffle 11 is driven to spring back and reset, which will seal the interior of the placement slot 9 to prevent impurities from entering the interior of the placement slot 9.

[0033] like Figure 1 - Figure 8 As shown, protective boxes 12 are fixedly connected to the left and right sides of the inner top wall of the cage 1. Each of the two protective boxes 12 is equipped with a motor 13. The protective boxes 12 are fixed in the inner top wall of the cage 1 to protect the motor 13 from the outside and to prevent the motor 13 from being affected by dust or other factors.

[0034] Two motors 13 have lead screws 14 fixedly connected to their output ends. Limiting rings 18 are fixedly connected to the bottom ends of the two lead screws 14. When the motors 13 are started, their output ends drive the lead screws 14 to rotate. The limiting rings 18 at the bottom ends of the lead screws 14 limit the movement of the internally threaded sleeves 15 on the outer side of the lead screws 14, preventing them from disengaging. The internally threaded sleeves 15 are slidably connected to the outer sides of the two lead screws 14. The threads inside the internally threaded sleeves 15 are threaded with the outer side of the lead screws 14, causing the internally threaded sleeves 15 to slide up and down on the outer side of the lead screws 14 after the lead screws 14 are rotated. Two internal threaded sleeves 15 are fixedly connected to outer cylinders 16 on their outer sides. The bottom ends of the two outer cylinders 16 are fixedly connected to bases 17. Two limiting rings 18 are set inside the two outer cylinders 16. The inner threaded sleeves 15 are threaded to the outer side of the lead screw 14, thereby connecting the outer side of the internal threaded sleeves 15 to the outer cylinders 16 and driving the bases 17 to slide up and down. Thus, the bases 17 are used to adjust and support the internal support height of the ventilation cage.

[0035] It should be noted that this utility model is a high-pressure-resistant ground ventilation cage for grain storage. First, the motor 13 is connected to an external power supply and controller to supply power to the device and to uniformly control the motor 13 and multiple motors 13.

[0036] When multiple ventilation cages need to be spliced ​​together, the locking block 5 on the right semicircular ring 2 of one ventilation cage is aligned with the placement groove 9 on the outer shell 6 of the left semicircular ring 2 of another ventilation cage. The ventilation cage is then pushed, causing the locking block 5 to gradually enter the placement groove 9. As the locking block 5 is inserted, it compresses the baffle 11 inside the placement groove 9. The baffle 11 is connected to the second spring 10. Under the pressure of the locking block 5, the baffle 11 compresses the second spring 10 and moves into the placement groove 9, making space for the locking block 5 to smoothly enter the placement groove 9.

[0037] When the slot on the locking block 5 aligns with the position of the support rod 7 inside the outer casing 6, the support rod 7, under the action of the first spring 8, pops back and inserts into the slot on the locking block 5. Since each support rod 7 inside the outer casing 6 is connected to four first springs 8, the first springs 8 continuously provide elastic force, causing the support rod 7 to be tightly locked in the slot on the locking block 5, thus firmly connecting the two ventilation cages together.

[0038] When the ventilation cage needs to be disassembled, the operator first presses down on the support rod 7. Upon further pressing, the rear wall of the support rod 7 compresses the first spring 8, causing the rear part of the support rod 7 to retract into the housing 6. This allows the rear part of the support rod 7 to disengage from the slot of the locking block 5. Once the support rod 7 is disengaged from the locking block 5, the locking block 5 is no longer restricted by the support rod 7. At this point, the compressed second spring 10 pushes the baffle 11, thereby pushing the locking block 5 out of the placement slot 9. The installer can then simply pull the ventilation cage apart to complete the separation of the two ventilation cages.

[0039] When the internal support height of the ventilation cage needs to be adjusted, the motor 13 inside the protective box 12 is started. The protective box 12 serves a protective function, preventing the motor 13 from being affected by adverse environmental factors such as grain dust and moisture, thus extending the service life of the motor 13. The output end of the motor 13 drives the lead screw 14 to rotate. The lead screw 14 and the internal threaded sleeve 15 are connected by threads. When the lead screw 14 rotates, the internal threaded sleeve 15 will move up and down along the axial direction of the lead screw 14 due to the interaction of the threads. Since the internal threaded sleeve 15 is fixedly connected to the outer cylinder 16, the outer cylinder 16 will rise and fall synchronously with the internal threaded sleeve 15. The bottom end of the outer cylinder 16 is connected to the base 17, and the base 17 ultimately realizes the adjustment of the internal support height of the ventilation cage.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
