Description

Technical Field

[0001] This utility model relates to the field of grain warehouse ventilation technology, specifically a ground cage for grain warehouse ventilation. Background Technology

[0002] In the process of grain storage, the ground cage ventilation system is a commonly used ventilation method. By laying ground cages on the floor of the grain warehouse, air can circulate in the grain warehouse to regulate the temperature and humidity and ensure the safety of grain storage.

[0003] 1. Currently, the ground cages are only prevented from deforming during use by using screws and nuts. There are no measures to support the top of the ground cages. This will cause the cages to deform and collapse due to the pressure of the grain covering them for a long time, making them unusable and resulting in poor stability.

[0004] 2. After the ground cage is installed, a ventilation net needs to be laid manually to prevent the grain from falling into the ventilation cage and causing ventilation blockage. Since the ground cage does not have a fixed measure for the ventilation net, multiple people are needed to lay the ventilation net, which is very inconvenient and results in poor practicality of the ground cage. Utility Model Content

[0005] To address the above problems, this utility model provides a ground cage for grain storage ventilation, which solves the aforementioned issues.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ground cage for ventilation in a grain warehouse, comprising a cage body and an integrally formed mounting arc plate at both ends of the cage body, wherein two bases are fixedly connected to the bottom ends of the cage body and the mounting arc plate, and a plurality of threaded rods are inserted into the interior of the cage body.

[0007] The lead screw is provided with a first support block on its outside. Two first support rods are fixedly connected to the top of the first support block, and a support arc plate is connected to the other end of the first support rod.

[0008] The lead screw is provided with two second support blocks on its outside. A second support rod is fixedly connected to the top of the second support block, and a first mounting shell is fixedly connected to one end of the second support rod.

[0009] A connecting arc plate is connected to one side of each of the two supporting arc plates, and two third supporting rods are fixedly connected to one side of each connecting arc plate. One end of each third supporting rod is connected to a second mounting shell.

[0010] Preferably, a slot is provided on one side of the base, and two springs are connected inside the slot. The other end of the spring is connected to a slide rod, and a block is fixedly connected to one end of the slide rod.

[0011] Preferably, a locking rod is inserted into the slot, the bottom end of the locking rod is arc-shaped, two arc grooves are formed on the outside of the locking rod, and a pressure plate is connected to the top of the locking rod.

[0012] Preferably, the supporting arc plate has a plurality of ventilation holes.

[0013] Preferably, the first mounting shell and the second mounting shell are disposed outside the first support rod, and the first mounting shell and the second mounting shell are connected by bolts.

[0014] Preferably, the lead screw is externally threaded with a plurality of nuts, which fix the lead screw, the first support block, and the second support block.

[0015] Preferably, the cage body has a plurality of bridge holes.

[0016] Preferably, the outer top of the mounting arc plate is provided with a splicing protrusion, and the inner top surface of the mounting arc plate is provided with a splicing groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This application uses a first support rod, a second support rod, a third support rod, etc. to support the cage body, preventing the cage body from being deformed or even collapsed when grain is put into the warehouse and covers the cage body. This improves the support of the cage body and solves the problem that the cage body will be deformed and damaged when grain is put into the warehouse, which will make the cage body unusable. This is conducive to improving the stability of the cage body.

[0019] 2. This application allows the support rod to be disassembled through the cooperation of the first mounting shell and the second mounting shell, which facilitates the storage and transportation of the ground cage. It also allows for quick installation of the support rod when in use, solving the problem that the storage and transportation of the ground cage is inconvenient when not in use, and improving the flexibility of the ground cage.

[0020] 3. This application uses a combination of clips, clips, and pressure plates to fix and install the ventilation net laid on the outside of the ground cage. This solves the problem that after the ground cage is installed, the ventilation net needs to be laid manually, and the ground cage does not have a measure to fix the ventilation net, which makes it very inconvenient for personnel to lay the ventilation net. This is beneficial to improving the practicality of the ground cage. Attached Figure Description

[0028] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0029] Please see Figures 1 to 6 A ground cage for ventilation in a grain warehouse includes a cage body 1 and an integrally formed mounting arc plate 2 at both ends of the cage body 1. The bottom ends of the cage body 1 and the mounting arc plate 2 are fixedly connected to two bases 3. Several threaded rods 11 are inserted into the inside of the cage body 1. When the ground cage is not in use, only the cage body 1, the mounting arc plate 2 and the bases 3 are present. At this time, the ground cages can be stacked and aligned, and stacked together for easy storage and transportation.

[0030] It should be noted that when using ground cages, several ground cages need to be spliced ​​together and laid in the grain silo. The last ground cage will have a tail cover connected to one side, and the first ground cage will be connected to an external centrifuge. The centrifuge will ventilate the grain silo through the ground cages.

[0031] External equipment centrifuges are well-known technology, and those skilled in the art can and should understand their specific functions and structures, so they will not be described in detail here.

[0032] The lead screw 11 is provided with a first support block 12 on its outside. Two first support rods 13 are fixedly connected to the top of the first support block 12, and the other end of the first support rod 13 is connected to a support arc plate 14.

[0033] Two second support blocks 16 are provided on the outside of the lead screw 11. A second support rod 17 is fixedly connected to the top of the second support block 16. A first mounting shell 18 is fixedly connected to one end of the second support rod 17.

[0034] Two supporting arc plates 14 are connected to a connecting arc plate 19 on one side. Two third supporting rods 20 are fixedly connected to one side of the connecting arc plate 19. One end of the third supporting rod 20 is connected to a second mounting shell 21. When using the ground cage, the personnel pass the screw rod 11 through one end of the cage body 1, and then, according to the sequence, first set one of the second supporting blocks 16 outside the screw rod 11.

[0035] Then, the first support block 12 is placed outside the lead screw 11. At this time, the support arc plate 14 will be aligned and abut against the inner wall of the cage 1. In this way, the support arc plate 14 supports the cage 1 through the cooperation of the first support rod 13 and the first support block 12.

[0036] Then, another second support block 16 is placed outside the lead screw 11. Similarly, the second support block 16 is adjusted to a suitable position so that the first mounting shell 18 abuts against the outside of the first support rod 13.

[0037] It should be further added that: nuts are connected to both sides of the first support block 12 and the two second support blocks 16. When installing and disassembling, the screw rod 11 is rotated and inserted into the interior of the first support block 12 and the two second support blocks 16. At this time, the nuts on both sides of the first support block 12 and the two second support blocks 16 will be threadedly connected to the screw rod 11, thereby fixing it.

[0038] Meanwhile, the lead screw 11 will pass through the other end of the cage 1, and personnel will fix the lead screw 11 with two nuts;

[0039] Finally, the connecting arc plate 19 is connected to the two supporting arc plates 14 by bolts, and the second mounting shell 21 abuts against the outside of the first support rod 13. Then, the personnel connect and fix the second mounting shell 21 to the first mounting shell 18 by bolts. This completes the installation of the support mechanism. Similarly, the support mechanism can be disassembled when storing the ground cage to facilitate the storage and transportation of the ground cage.

[0040] After the support mechanism is installed, it will form several triangular support structures. Triangles are stable and not easily deformed, which allows the ground cage to effectively resist the pressure generated by the accumulation of grain, prevent deformation, collapse and other situations, ensure the overall structure of the ground cage is stable, and maintain its ventilation function in normal operation.

[0041] Furthermore, multiple support components are connected to the ground cage, which disperses the stress points, making the overall structure more evenly stressed when bearing the pressure of grain, and reducing the risk of damage to the ground cage caused by local stress concentration;

[0042] It should be noted that, in order to prevent the supporting arc plate 14 from affecting the ventilation at the corresponding position of the cage 1, several ventilation holes 15 are provided on the supporting arc plate 14, so that normal ventilation can be ensured at the contact point between the supporting arc plate 14 and the cage 1.

[0043] A slot 4 is provided on one side of the base 3. Two springs 5 ​​are connected inside the slot 4. The other end of the springs 5 ​​is connected to a slide rod 6. One end of the slide rod 6 is fixedly connected to a locking block 7.

[0044] A locking rod 8 is inserted into the inside of the slot 4. The bottom end of the locking rod 8 is arc-shaped. Two arc grooves 9 are opened on the outside of the locking rod 8. A pressure plate 10 is connected to the top of the locking rod 8. When laying the ventilation net, the personnel first lay the ventilation net on the top of the ground cage. Then the personnel can insert the pressure plate 10 and the locking rod 8 into the slot 4. At this time, the locking rod 8 descends and squeezes open the two locking blocks 7 (the shape of the locking blocks 7 is spherical) through the arc-shaped bottom end, so that the locking blocks 7 drive the slide rod 6 to squeeze the spring 5. The spring 5 will generate a force that resists the slide rod 6.

[0045] As the lever 8 continues to descend, the arc groove 9 will reach the locking block 7. Because the spring 5 has a force that resists the sliding rod 6, the locking block 7 will enter the interior of the arc groove 9, so that the locking block 7 and the arc groove 9 cooperate to position the lever 8. At this time, the bottom of the pressure plate 10 contacts the top of the base 3, so that the pressure plate 10 fixes the ventilation net. Then, the ventilation net is partially fixed, and personnel can easily continue to lay the ventilation net.

[0046] It should be further noted that because the locking block 7 is spherical and the groove of the locking rod 8 is also an arc groove 9, they have a certain degree of interlocking during normal use, preventing the locking rod 8 from easily coming out of the locking groove 4. At the same time, when separating the locking rod 8 from the locking block 7, personnel can directly lift the pressure plate 10 and the locking rod 8 manually, and the spherical locking block 7 will easily separate from the arc groove 9 of the locking rod 8. Therefore, personnel can easily fix the ventilation screen, and can also easily loosen the fixation of the ventilation screen during disassembly without the need for additional tools, which greatly improves the work efficiency of personnel.

[0047] Several ventilation holes 15 are provided on the supporting arc plate 14.

[0048] The first mounting shell 18 and the second mounting shell 21 are disposed outside the first support rod 13, and the first mounting shell 18 and the second mounting shell 21 are connected by bolts.

[0049] The lead screw 11 has several nuts connected to its external threads, which fix the lead screw 11, the first support block 12, and the second support block 16.

[0050] Several bridge holes 22 are provided on the cage body 1.

[0051] The outer top of the mounting arc plate 2 is provided with splicing protrusions, and the inner top surface of the mounting arc plate 2 is provided with splicing grooves. When splicing the ground cages, the mounting arc plate 2 of one ground cage is placed on top of the mounting arc plate 2 of another ground cage. At this time, the splicing protrusions on the mounting arc plate 2 will be inserted and matched with the splicing grooves. Then, the personnel will connect and fix the two mounting arc plates 2 with bolts. After the ground cages are laid, the personnel will cover and lay a layer of ventilation net.

[0052] When using this utility model:

[0053] First, when the ground cage is not in use, there is only the cage body 1, the mounting arc plate 2, and the base 3. At this time, the ground cages can be stacked and aligned together for easy storage and transportation. When the ground cage is in use, several ground cages need to be spliced ​​together and laid in the grain silo. The last ground cage will have a tail cover connected to one side, and the front ground cage will be connected to the external equipment centrifuge. The centrifuge ventilates the grain silo through the ground cage.

[0054] Secondly, when using the ground cage, the operator passes the lead screw 11 through one end of the cage body 1, and then, in sequence, first sets one of the second support blocks 16 outside the lead screw 11; then sets the first support block 12 outside the lead screw 11. At this time, the support arc plate 14 will be aligned and abut against the inner wall of the cage body 1. In this way, the support arc plate 14 supports the cage body 1 through the cooperation of the first support rod 13 and the first support block 12. Then, another second support block 16 is set outside the lead screw 11. Similarly, the second support block 16 is adjusted to a suitable position so that the first mounting shell 18 abuts against the outside of the first support rod 13.

[0055] Then, the lead screw 11 passes through the other end of the cage body 1. Personnel fix the lead screw 11 with two nuts, and then connect the connecting arc plate 19 to the two supporting arc plates 14 with bolts. At the same time, the second mounting shell 21 abuts against the outside of the first support rod 13. Then, personnel connect and fix the second mounting shell 21 to the first mounting shell 18 with bolts. This completes the installation of the support mechanism. Similarly, the support mechanism can be disassembled when storing the ground cage to facilitate the storage and transportation of the ground cage.

[0056] Finally, when splicing the ground cages, the mounting arc plate 2 of one ground cage is placed on top of the mounting arc plate 2 of the other ground cage. At this time, the splicing protrusions on the mounting arc plate 2 will engage with the splicing groove. Then, the two mounting arc plates 2 are connected and fixed with bolts. After the ground cages are laid, a layer of ventilation netting is laid on top. When laying the ventilation netting, the pressure plate 10 and the clamping rod 8 can be inserted into the clamping groove 4. At this time, the clamping rod 8 descends and squeezes open the two clamping blocks 7 (the clamping blocks 7 are spherical) through the arc-shaped bottom end. This causes the locking block 7 to drive the sliding rod 6 to compress the spring 5, and the spring 5 will generate a force to resist the sliding rod 6. As the locking rod 8 continues to descend, the arc groove 9 will reach the locking block 7. Because the spring 5 has a force to resist the sliding rod 6, the locking block 7 will enter the interior of the arc groove 9, so that the locking block 7 and the arc groove 9 cooperate to position the locking rod 8. At this time, the bottom of the pressure plate 10 contacts the top of the base 3, so that the pressure plate 10 fixes the ventilation net. Then, the ventilation net is partially fixed, and personnel can easily continue to lay the ventilation net.

[0057] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
