A hook-type silage bag hanger

Abstract

This utility model relates to the field of hanging frame technology, specifically a hook-type silage bag hanging frame, including a shelf. Vertical rods are fixedly installed on the upper surface of the shelf, near the four corners. A horizontal rod is fixedly installed at the top of each vertical rod on an adjacent side. A second vertical rod is inserted into the upper surface of the horizontal rod. By setting up a buffer assembly consisting of a sleeve, a sliding rod, and a spring, when vibration occurs during lifting, stopping, or transportation, the sliding rod can slide smoothly within the sleeve and, in conjunction with the elastic deformation of the spring, absorb vibration energy. This effectively reduces the impact of vibration on the frame connecting block, heavy-duty collar, and the silage bags below, preventing the bags from shifting or slipping due to vibration. It also reduces vibration wear on the connecting components of the hanging frame, extending the overall service life of the equipment.

Description

Technical Field

[0001] This utility model relates to the field of hanging rack technology, specifically a hook-type silage bag hanging rack. Background Technology

[0002] In the livestock production sector, silage, with its long storage period, low nutrient loss, and good palatability, has become an important material for ensuring the supply of livestock feed in large-scale farming. For ease of storage and transportation, silage is usually packaged in bags. However, during feed transfer within farms, warehouse loading and unloading operations, or cross-regional transportation, hoisting racks in conjunction with cranes and other lifting equipment are needed to achieve efficient lifting and moving of silage bags. Therefore, hook-type silage bag racks are a key auxiliary equipment in the livestock logistics process.

[0003] However, existing hook-type silage bag hangers have many design flaws in practical applications, making it difficult to meet the safety and practicality requirements of livestock production. On the one hand, most hangers lack effective cushioning and shock absorption structures, easily causing severe vibrations due to inertia when starting, stopping, or encountering bumps during transport. This vibration not only leads to uneven stress on the hanger's connecting parts, potentially causing loosening, deformation, or even breakage over time, shortening the equipment's lifespan, but also causes the silage bags placed on the hanger's bearing surface to shake violently. This can result in minor issues like bag displacement, affecting subsequent loading and unloading efficiency, or even causing the bags to slip off the hanger's edge, wasting feed and posing a safety hazard of injuring operators or damaging surrounding equipment.

[0004] On the other hand, the existing hoists lack ease of assembly and disassembly. Some hoists use bolted connections between the horizontal and vertical bars, requiring specialized tools like wrenches for assembly and disassembly, making the process cumbersome and time-consuming. Other hoists use an integrated welded structure, which, while securely connected, cannot be disassembled, taking up significant space and offering extremely poor flexibility when stored or transported to confined work areas. Furthermore, existing hoists lack adequate positioning measures for silage bags, mostly relying solely on the bearing surface for support without adjustable side restraints. When bag sizes vary significantly or swaying occurs during hoisting, the bags easily tilt along the edge of the bearing surface, further increasing the risk of accidents. These problems not only reduce the efficiency of silage bag transport but also increase equipment maintenance costs and the incidence of accidents, making them unsuitable for the large-scale, high-efficiency production demands of modern livestock farming. Therefore, structural optimization and improvement of hook-type silage bag hoists are urgently needed. In light of this, we propose a hook-type silage bag hoist. Utility Model Content

[0005] The purpose of this utility model is to provide a hook-type silage bag hanger to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A hook-type silage bag hanger includes:

[0008] A shelf is provided, with vertical rods fixedly installed on the upper surface of the shelf and near the four corners. A horizontal rod is fixedly installed at the top of the vertical rod on the adjacent side. A second vertical rod is inserted into the upper surface of the first horizontal rod. An arc-shaped shackle is fixedly installed at the top of the second vertical rod. A frame-shaped connecting block is provided between the four arc-shaped shackles. A hanging rope is provided between the frame-shaped connecting block and the four arc-shaped shackles. A heavy-duty collar is fixedly installed at the center of the upper surface of the frame-shaped connecting block.

[0009] A suspension mechanism is provided, which is positioned directly above the heavy-duty collar and is used to lift the heavy-duty collar.

[0010] Four sets of fixing components are respectively set on both sides of the two horizontal bars and used to fix the four vertical bars.

[0011] Preferably, the suspension mechanism includes:

[0012] A connecting plate is positioned directly above the frame-shaped connecting block. A fixing ring is positioned directly below the connecting plate. A hook is fixed at the center of the lower surface of the fixing ring, and the hook is engaged with a heavy-duty collar. A buffer assembly is positioned on the upper surface of the fixing ring.

[0013] Preferably, the buffer component includes:

[0014] A sleeve is fixedly installed at the center of the upper surface of a fixing ring. A sliding rod is slidably installed inside the sleeve, and the top end of the sliding rod is fixed to the middle of the lower surface of a connecting plate. A spring is fixedly installed on the upper surface of the fixing ring outside the circumference of the sleeve, and the other end of the spring is fixed to the lower surface of the connecting plate.

[0015] Preferably, the inner sidewall of the second vertical rod is provided with an embedding groove, and the second horizontal rod is slidably installed between the two embedding grooves on opposite sides.

[0016] Preferably, the fixing component includes:

[0017] The insert is fixedly installed on the lower surface of the second vertical rod. A slot is provided on the upper surface of the first horizontal rod at a position corresponding to the insert. A sliding groove is provided on the periphery of the first horizontal rod near the slot. A slider is slidably installed in the sliding groove. A second spring is fixed on the side of the slider away from the slot. A limit block is fixed on the side of the slider near the slot, and one end of the limit block extends into the slot. A limit hole is provided on the insert to match the limit block. The limit block and the limit hole are inserted into each other.

[0018] Preferably, the cross-section of the limiting block is a right-angled trapezoidal structure, and the inclined end of the limiting block is oriented towards the insert block.

[0019] Preferably, an opening is provided on the outer wall of the crossbar near the slide groove, and a toggle plate is slidably installed in the opening, and the toggle plate is fixed to the corresponding slider.

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

[0021] 1. This hook-type silage bag hanger, through the setting of a buffer assembly consisting of a sleeve, a sliding rod and a spring, allows the sliding rod to slide smoothly within the sleeve and absorb vibration energy in conjunction with the elastic deformation of the spring when vibration occurs during hoisting, starting, stopping or transportation. This effectively reduces the impact of vibration on the frame connecting block, heavy-duty collar and the silage bag below, preventing the bag from shifting or slipping due to vibration. At the same time, it reduces vibration wear on the connecting parts of the hanger and extends the service life of the overall equipment.

[0022] 2. This hook-type silage bag hanger uses a plug-in structure consisting of inserts, slots, limit blocks, and limit holes for its fixing components. The limit blocks are designed with a right-angled trapezoidal shape with the inclined end facing the insert, enabling automatic locking of the second vertical bar and the first horizontal bar. Installation can be completed without the need for additional tools. At the same time, the slider can be quickly pushed by the actuating plate to disengage the limit block from the limit hole, enabling rapid separation of the second vertical bar and the first horizontal bar. This significantly improves the assembly and disassembly efficiency of the hanger and facilitates the transportation, transfer, and storage of the equipment.

[0023] 3. This hook-type silage bag hanger, by creating an embedded groove on the inner side wall of the second vertical bar and slidingly installing the second horizontal bar, allows for flexible adjustment of the limiting position of the second horizontal bar according to the height of the silage bag, providing stable constraint on the bag from the side and preventing the bag from slipping off the edge of the shelf during hoisting. Furthermore, the shelf, as the base for placing the bag, together with the first vertical bar at the four corners, the first horizontal bar, and the second vertical bar, forms a stable frame structure that can evenly bear the weight of the bag, further improving the safety and stability of the hoisting process.

For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items, and therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0031] Please see Figure 1 - Figure 4 As shown, this utility model provides a technical solution:

[0032] A hook-type silage bag hanger includes:

[0033] A shelf 1 is provided. Vertical rods 2 are fixedly installed on the upper surface of the shelf 1 and near the four corners. A horizontal rod 3 is fixedly installed at the top of the vertical rod 2 on the adjacent side. A vertical rod 4 is inserted into the upper surface of the horizontal rod 3. An arc-shaped shackle 5 is fixedly installed at the top of the vertical rod 4. A frame-shaped connecting block 6 is provided between the four arc-shaped shackles 5. A hanging rope 7 is provided between the frame-shaped connecting block 6 and the four arc-shaped shackles 5. A heavy-duty collar 8 is fixedly installed at the center of the upper surface of the frame-shaped connecting block 6.

[0034] The suspension mechanism is located directly above the heavy-duty collar 8 and is used to complete the hoisting of the heavy-duty collar 8.

[0035] Four sets of fixing components are respectively set on both sides of the two horizontal bars 3, and are used to fix the four vertical bars 4.

[0036] In this embodiment, the suspension mechanism includes:

[0037] A connecting plate 9 is positioned directly above the frame-shaped connecting block 6. A fixing ring 10 is positioned directly below the connecting plate 9. A hook 11 is fixed at the center of the lower surface of the fixing ring 10, and the hook 11 engages with the heavy-duty collar 8. A buffer assembly is provided on the upper surface of the fixing ring 10. The connecting plate 9 needs to be fixedly connected to the lifting end of external lifting equipment (such as a crane) to provide lifting support for the entire gantry. The fixing ring 10 is made of high-strength metal to ensure it can stably bear the weight of the hook 11 and the entire gantry below, preventing deformation due to excessive force. The opening size of the hook 11 is matched to the outer diameter of the heavy-duty collar 8, and the inner wall of the hook 11 is smoothed to reduce friction loss when the hook 11 engages with the heavy-duty collar 8, ensuring the stability of the engagement.

[0038] In this embodiment, the buffer component includes:

[0039] Sleeve 12 is fixedly installed at the center of the upper surface of the fixing ring 10. A sliding rod 13 is slidably installed inside the sleeve 12, and the top end of the sliding rod 13 is fixed to the middle of the lower surface of the connecting plate 9. A spring 14 is fixedly installed on the upper surface of the fixing ring 10 and outside the circumference of the sleeve 12, and the other end of the spring 14 is fixed to the lower surface of the connecting plate 9. The inner wall of the sleeve 12 is precision machined, and the gap between it and the outer wall of the sliding rod 13 is controlled within the range of 0.5 to 1 mm. This ensures that the sliding rod 13 can slide smoothly in the vertical direction within the sleeve 12, avoiding jamming of the sliding rod 13 and affecting the buffering effect. The spring 14 adopts a high-strength spring structure, and there are 3-4 sets evenly distributed along the circumference of the sleeve 12. The initial elastic force of each set of springs 14 is consistent. When vibration occurs during the lifting or lowering of the silage bag by the hanger, the sliding rod 13 slides within the sleeve 12 and squeezes or stretches the spring 14. The spring 14 absorbs the vibration energy through its own elastic deformation, realizing buffering and shock absorption, and reducing the impact of vibration on the frame connecting block 6 and the underlying structure.

[0040] In this embodiment, the inner wall of the second vertical rod 4 is provided with an embedding groove 15, and a second horizontal rod 16 is slidably installed between two embedding grooves 15 on opposite sides. The embedding grooves 15 are evenly spaced along the height direction of the second vertical rod 4, and the distance between the grooves of two adjacent embedding grooves 15 is 5-8cm, so as to flexibly adjust the installation position of the second horizontal rod 16 according to the height of the silage bag. The second horizontal rod 16 adopts a hollow metal rod structure, which reduces the overall weight while ensuring its own strength. The length of the second horizontal rod 16 is adapted to the distance between the two opposite vertical rods 4. After its two ends are inserted into the opposite embedding grooves 15, it can be temporarily fixed by the weight of the second horizontal rod 16 itself and the friction of the groove wall of the embedding groove 15. When the position needs to be adjusted, the second horizontal rod 16 can be slid along the embedding groove 15 simply by lifting it up. The operation is convenient and can effectively limit the silage bag placed above the shelf 1 from the side, preventing the bag from slipping during hoisting.

[0041] In this embodiment, the fixing component includes:

[0042] Insert 17 is fixedly installed on the lower surface of vertical rod 2 4. A slot 18 is provided on the upper surface of horizontal rod 1 3 at the position corresponding to insert 17. A sliding groove 19 is provided in the horizontal rod 1 3 and on the periphery near the slot 18. A slider 20 is slidably installed in the sliding groove 19. A spring 21 is fixed on the side of slider 20 away from the slot 18. A limiting block 22 is fixed on the side of slider 20 near the slot 18, and one end of the limiting block 22 extends into the slot 18. A limiting hole 23 is provided on insert 17 that matches the limiting block 22. The limiting block 22 and the limiting hole 23 are inserted and engaged. The insert 17 can also adopt a cylindrical structure, with the gap between its outer diameter and the inner diameter of the slot 18 not exceeding 0.3mm. This ensures that the insert 17 can maintain coaxiality with the horizontal bar 3 after being inserted into the slot 18, and prevents the vertical bar 4 from tilting due to excessive gap between the insert 17 and the slot 18. The groove depth of the slide 19 is greater than the length of the limiting block 22, ensuring that when the slider 20 slides in the slide 19, the limiting block 22 can be completely retracted into the slide 19, making it easy for the insert 17 to be inserted into or removed from the slot 18. The spring 21 is a compression spring, which in its natural state generates a pushing force on the slider 20 toward the slot 18, so that the limiting block 22 always remains extended out of the slide 19 and inserted into the limiting hole 23, thereby stably fixing the insert 17 in the slot 18, realizing a reliable connection between the vertical bar 4 and the horizontal bar 3, and preventing the vertical bar 4 and the horizontal bar 3 from separating during hoisting.

[0043] In this embodiment, the cross-section of the limiting block 22 is a right-angled trapezoidal structure, and the inclined end of the limiting block 22 is set towards the insert block 17. The inclined end design of the right-angled trapezoidal structure enables automatic guidance and locking during the insertion of the insert 17 into the slot 18: when the insert 17 is inserted from above the slot 18, the lower end face of the insert 17 contacts the inclined end of the limiting block 22. As the insert 17 moves downward, it generates a pressing force perpendicular to the inclined surface on the inclined end of the limiting block 22. This pressing force can be decomposed into a component force along the length of the slide groove 19 (away from the slot 18), pushing the slider 20 to slide along the slide groove 19 and compressing the second spring 21, causing the limiting block 22 to gradually retract into the slide groove 19. When the limiting hole 23 on the insert 17 moves to be flush with the limiting block 22, the compression force of the second spring 21 is released, pushing the slider 20 to move towards the slot 18, causing the limiting block 22 to be inserted into the limiting hole 23, thus completing the automatic fixing of the second vertical rod 4 and the first horizontal rod 3 without additional manual operation, simplifying the installation process.

[0044] In this embodiment, an opening 24 is provided on the outer wall of the crossbar 3 near the slide groove 19. A toggle plate 25 is slidably installed in the opening 24, and the toggle plate 25 is fixed to the corresponding slider 20. The length of the opening 24 is the same as the length of the slide groove 19, and the width of the opening 24 is matched with the width of the actuating plate 25 to prevent the actuating plate 25 from shifting during sliding and to ensure that the actuating plate 25 can drive the slider 20 to slide stably along the length direction of the slide groove 19. The outer surface of the actuating plate 25 is treated with anti-slip treatment (such as anti-slip texture), and the outer end of the actuating plate 25 extends 3-5mm beyond the opening 24, making it convenient for operators to actuate the actuating plate 25 with their fingers or tools. When it is necessary to disassemble the second vertical rod 4, the actuating plate 25 is actuated away from the slot 18. The actuating plate 25 drives the slider 20 to compress the second spring 21, so that the limiting block 22 disengages from the limiting hole 23 on the insert block 17. At this time, the second vertical rod 4 can be pulled out upwards, realizing the quick separation of the second vertical rod 4 from the first horizontal rod 3, which is convenient for the disassembly, transportation or storage of the hanger.

[0045] When using the hook-type silage bag hanger of this embodiment:

[0046] First, fix the two horizontal bars 3 to the top of the vertical bars 2 near the four corners on the upper surface of the shelf 1, ensuring that the horizontal bars 3 and vertical bars 2 are firmly connected. Then, pick up the vertical bar 4 and align its lower end with the upper surface of the horizontal bar 3, so that the insert 17 on the lower surface of the vertical bar 4 is accurately inserted into the slot 18 on the horizontal bar 3. During the insertion process, the insert 17 presses the inclined end of the limiting block 22, pushes the slider 20 to compress the spring 21 and causes the limiting block 22 to retract into the slide groove 19. When the insert 17 is fully inserted into the slot 18 and the limiting hole 23 is aligned with the limiting block 22, the spring 21 resets and pushes the limiting block 22 into the limiting hole 23, thus completing the automatic fixing of the vertical bar 4 and the horizontal bar 3.

[0047] Next, based on the height of the silage bag to be hoisted, slide the crossbar 16 between the two opposite embedded slots 15 and adjust it to a position that can effectively limit the side of the silage bag; then place the silage bag stably on the upper surface of the placement plate 1, ensuring that the center of gravity of the silage bag coincides with the center of the placement plate 1 to avoid the center of gravity shifting during hoisting; then fix the hoisting end of the external hoisting equipment (such as a crane) to the connecting plate 9, adjust the position of the hoisting equipment so that the hook 11 below the fixing ring 10 is accurately hooked at the heavy-duty collar 8 on the upper surface of the frame connecting block 6, and check whether the hooking is firm;

[0048] Start the hoisting equipment. If vibration occurs during hoisting, the sliding rod 13 slides vertically within the sleeve 12. At the same time, the spring 14 absorbs vibration energy through elastic deformation, achieving buffering and shock absorption to prevent the feed bag from shaking. After the hoist is transported to the target position, slowly lower the hoist and remove the silage bag. If the hoist needs to be disassembled, move the actuating plate 25 away from the slot 18 to drive the slider 20 to compress the spring 21, causing the limiting block 22 to disengage from the limiting hole 23. Pull out the vertical rod 4, then separate the horizontal rod 3 from the vertical rod 2. Finally, sort and store all components for later use.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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 preferred examples and are not intended to limit the utility model.
