Description
Technical Field
[0001] This utility model relates to the field of ton bag breaking and filling technology, and in particular to a circumferential cutting and breaking mechanism for fertilizer ton bags. Background Technology
[0002] Fertilizer ton bags are large, flexible transport packaging containers used for packaging fertilizers. They are also known as bulk bags or space bags. They are generally made of polyester fibers such as polypropylene and polyethylene. Compared with traditional small or medium-sized bags, fertilizer ton bags have a large capacity, are easy to load and unload, and can be operated with cranes or forklifts. They can greatly reduce the labor intensity of farmers, improve work efficiency, and effectively reduce the consumption of packaging materials, which is in line with the green and environmentally friendly development concept of modern agriculture. Fertilizer ton bags use a breaking mechanism during use.
[0003] Traditional methods of breaking down ton bags rely on manual hand-held cutters or simple frames to hold the cutter bar in place, which have several shortcomings in practical use. For example, they pose significant safety hazards. When manually cutting the bag with a cutter, the operator must be in close contact with the sharp blade; if the bag shakes, the operator's hand is unsteady, or the operator is fatigued, cuts to fingers and arms are highly likely. Similarly, with simple frames holding the cutter bar in place, the blade is constantly exposed without any physical protection, making it easy for personnel to accidentally touch and injure themselves when passing by, cleaning equipment, or handling damaged bags. Furthermore, the breaking efficiency is low. Manual cutting relies on individual skill, is slow and inefficient, and is difficult to adapt to the needs of processing large quantities of ton bags. Manual cutting is also prone to problems such as "cutting too small" or "cutting off-center or missing cuts," causing material to flow out uncontrollably and requiring repeated cutting, increasing the operational steps and limiting the process. Utility Model Content
[0004] One of the technical problems this application aims to solve is that traditional ton bags rely on manual cutting with a knife or a simple frame to fix the knife strips and then manually push the ton bag for breaking and filling, which has many shortcomings in actual use.
[0005] To address the aforementioned technical problems, this application provides a fertilizer ton bag ring-cutting and crushing mechanism, comprising a U-shaped frame, a protective plate slidably engaged in the middle of the U-shaped frame, a horizontal toothed plate fixedly installed at one end of the protective plate, a sealing groove formed at one end of the middle of the U-shaped frame, mounting holes formed on both sides of the lower middle of the sealing groove, a rotating shaft rotatably mounted in the middle of the mounting holes, gears fixedly mounted at both ends of the rotating shaft, a side mounting groove formed on one side of the middle of the U-shaped frame, a limit groove formed in the middle of one end of the side mounting groove, a vertical toothed plate slidably engaged in the middle of the side mounting groove, a square plate fixedly mounted on one side of the upper end of the vertical toothed plate, hooks fixedly mounted at the four corners of the lower end of the square plate, a fixing plate fixedly mounted at one end of the U-shaped frame, a second sliding groove formed on one side of the upper end of the fixing plate, and a hollow groove formed at one end of the U-shaped frame.
[0006] In some embodiments, a ton bag placement groove is formed between the upper ends of the protective plate and the U-shaped frame, a hopper is fixedly installed in the middle of the U-shaped frame, and the square plate is located in the middle of the ton bag placement groove.
[0007] In some embodiments, a plurality of cross baffles are fixedly installed below the middle of the hopper, and a plurality of discharge ports are opened in the middle of the cross baffles.
[0008] In some embodiments, multiple support frames are fixedly installed around the center of the hopper, and spikes are fixedly installed at the upper ends of the center of the multiple support frames. Multiple cutting blades are fixedly installed around the spikes.
[0009] In some embodiments, the protective plate is slidably engaged with the upper end of the hopper, and a discharge trough is formed between the lower end of the hopper and the lower end of the U-shaped frame.
[0010] In some embodiments, a bracket is fixedly installed on one side of the upper end of the U-shaped frame, and a telescopic rod is fixedly installed in the middle of the bracket. The output end of the telescopic rod passes through the U-shaped frame and is fixedly connected to the upper end of the vertical toothed plate.
[0011] In some embodiments, the two gears are respectively located above one side of the middle portion of the slide groove and in the middle of the side mounting groove. The gear located in the middle of the side mounting groove meshes with a vertical gear plate, and the gear located in the slide groove meshes with a horizontal gear plate.
[0012] In some embodiments, the first slide and the second slide are connected, the horizontal toothed plate is slidably engaged in the middle of the first slide and the second slide, the protective plate is slidably engaged in the middle of the U-shaped frame through the horizontal toothed plate, and the protective plate is slidably engaged in the middle of the empty slot.
[0013] This utility model has at least the following beneficial effects:
[0014] 1. When in use, the device achieves automatic opening and closing of the protective plate through precise transmission of the vertical toothed plate, gear, and horizontal toothed plate. It can be raised and lowered synchronously with the ton bag to complete the integrated linkage of bag breaking operation. During operation, the protective plate automatically moves away to not block the bag breaking, and when not in operation, it automatically resets to isolate the spikes and cutting blades.

[0015] 2. In use, this utility model ensures thorough bag breaking and smooth material handling. On one hand, the ton bag placement slot and hook work together to position the ton bag, while the spiked cone precisely pierces and multiple cutting blades cut the bag comprehensively, ensuring no dead corners in bag breaking and minimal material residue. On the other hand, the hopper quickly collects the material, cross baffles intercept and disperse fragments, and the material is then directed out through the discharge chute, forming a complete channel. This effectively avoids material spillage, waste, and blockage, making it suitable for large-scale fertilizer processing needs. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Reference Figures 1 to 6 As shown, one embodiment of this utility model includes a U-shaped frame 1. A protective plate 2 is slidably engaged in the middle of the U-shaped frame 1. A horizontal toothed plate 31 is fixedly installed at one end of the protective plate 2. A sealing groove 21 is opened at one end of the middle of the U-shaped frame 1. Mounting holes 25 are opened on both sides of the lower middle of the sealing groove 21. A rotating shaft 29 is rotatably installed in the middle of the mounting holes 25. Gears 30 are fixedly installed at both ends of the rotating shaft 29. A side mounting groove 26 is opened on one side of the middle of the U-shaped frame 1. A limit groove 27 is opened in the middle of one end of the side mounting groove 26. A vertical toothed plate 28 is slidably engaged in the middle of the side mounting groove 26. A square plate 32 is fixedly installed on one side of the upper end of the vertical toothed plate 28. Hooks 33 are fixedly installed at the four corners of the lower end of the square plate 32. A fixing plate 23 is fixedly installed at one end of the U-shaped frame 1. A second sliding groove 24 is provided on one side of the upper end of plate 23. A slot 36 is provided at one end of U-shaped frame 1. A bracket 34 is fixedly installed on one side of the upper end of U-shaped frame 1. A telescopic rod 35 is fixedly installed in the middle of bracket 34. The output end of telescopic rod 35 passes through U-shaped frame 1 and is fixedly connected to the upper end of vertical toothed plate 28. Two gears 30 are located above one side of the middle of sliding groove 22 and in the middle of side mounting groove 26, respectively. The gear 30 in the middle of side mounting groove 26 meshes with vertical toothed plate 28. The gear 30 in sliding groove 22 meshes with horizontal toothed plate 31. Sliding groove 22 and sliding groove 24 are connected. Horizontal toothed plate 31 is slidably engaged in the middle of sliding groove 22 and sliding groove 24. Protective plate 2 is slidably engaged in the middle of U-shaped frame 1 through horizontal toothed plate 31. Protective plate 2 is slidably engaged in the middle of slot 36.
[0025] In this embodiment, during use, the protective plate 2 forms a linkage structure with the horizontal toothed plate 31, gear 30, and vertical toothed plate 28. When the equipment is running, the vertical toothed plate 28 drives the hook 33 to descend, and the protective plate 2 can automatically slide out of the slot 36, thus exposing the spikes 18 and multiple cutting blades 19 inside the hopper 14, facilitating the breaking and loading of ton bags. During use, the four hooks 33 at the lower end of the square plate 32 are used to hang the pull straps at the four corners of the ton bag. When the telescopic rod 35 drives the vertical toothed plate 28 to rise and fall, it will drive the gear 30 meshing with it to rotate. When the gear 30 meshing with the vertical toothed plate 28 rotates, it will be transmitted through the rotating shaft 29, and then... The gear 30 located inside the slide 22 rotates, which in turn drives the horizontal toothed plate 31 and the protective plate 2 to slide along the slide 22 and the slide 24. At this time, the protective plate 2 will move away from the top of the hopper 14, thus removing its obstruction. After the operation is completed, the protective plate 2 can be reset as the vertical toothed plate 28 rises. This does not affect the delivery of the ton bag, and it can also physically isolate the spike 18 and the cutting blade 19 in the non-operation state, greatly reducing the risk of accidental contact and making it highly practical. The tooth pitch and transmission ratio of the vertical toothed plate 28 and the horizontal toothed plate 31 are matched.
[0026] Example 2, as Figures 1 to 6 As shown, a ton bag placement groove 11 is formed between the upper ends of the protective plate 2 and the U-shaped frame 1. A feeding hopper 14 is fixedly installed in the middle of the U-shaped frame 1. A square plate 32 is located in the middle of the ton bag placement groove 11. Multiple cross baffles 15 are fixedly installed below the middle of the feeding hopper 14. Multiple feeding ports 16 are opened in the middle of the cross baffles 15.
[0027] In this embodiment, the ton bag placement groove 11 formed by the protective plate 2 and the upper end of the U-shaped frame 1 provides a clear placement area for the ton bags; the square plate 32 and hook 33 are located in the middle of the ton bag placement groove 11, which can be used to position the ton bags in conjunction with the placement groove, keeping the ton bags stable during the bag breaking process and reducing problems such as uneven local force and incomplete bag breaking caused by the shaking of the ton bags; the hopper 14 can quickly collect the material after bag breaking, preventing the material from scattering into the gaps inside the equipment and reducing residual waste; at the same time, the funnel-shaped structure accelerates the material flow and reduces the risk of blockage. The grid structure formed by multiple cross baffles 15 can perform preliminary filtering of the falling material, which can intercept larger ton bag fragments and disperse the material through multiple discharge ports 16, avoiding the material overflow caused by the instantaneous accumulation of a large amount of material.
[0028] Example 3, as Figures 1 to 6As shown, multiple support frames 17 are fixedly installed around the middle of the hopper 14. A spike 18 is fixedly installed at the upper end of the middle of the multiple support frames 17. Multiple cutting blades 19 are fixedly installed around the spike 18. The protective plate 2 is slidably snapped onto the upper end of the hopper 14. A feeding groove 13 is formed between the lower end of the hopper 14 and the lower end of the U-shaped frame 1.
[0029] In this embodiment, the spike 18 fixed by the support frame 17 can be precisely pierced from the bottom of the ton bag, and then combined with multiple cutting blades 19 around the perimeter to form a multi-directional cut, which can more thoroughly cut the ton bag and reduce material residue. The multi-directional distribution of the cutting blades 19 can adapt to the natural drooping shape of the ton bag under the action of gravity, ensuring that the bag body at different positions can be effectively cut open. The spike 18 and the cutting blades 19 are located in the middle of the hopper 14. Combined with the positioning of the ton bag placement slot 11, the bag breaking component can accurately act on the core area at the bottom of the ton bag, avoiding incomplete bag breaking caused by cutting position deviation, and improving the success rate of single bag breaking. Multiple support frames 17 fix the spike 18 and the cutting blades 19 from all sides of the hopper 14, dispersing the impact force when breaking the bag, avoiding deformation or breakage of a single fixed point due to excessive force, and extending the service life of vulnerable parts.
[0030] Working principle: When the equipment is not in operation, the protective plate 2 will fit tightly against the upper end of the hopper 14, physically isolating the spikes 18 and cutting blades 19 inside to prevent accidental injury to workers. The vertical toothed plate 28 is in the raised position, which moves the square plate 32 and hooks 33 above the ton bag placement slot 11, making it easy for operators to hang the ton bags. Then, the operator uses a forklift to place the ton bag in the ton bag placement slot 11 formed by the protective plate 2 and the upper end of the U-shaped frame 1, and hangs the pull straps at the four corners of the ton bag on the four hooks 33 at the lower end of the square plate 32. Through the synergistic action of the placement slot and the hooks 33, the ton bag is accurately positioned and fixed, ensuring that the bottom of the ton bag is aligned with the bag-breaking component in the middle of the hopper 14.
[0031] During the breaking and loading operation, the telescopic rod 35 is activated to drive the vertical toothed plate 28 downward. Through the meshing transmission of gears 30, the two gears 30 on the rotating shaft 29 rotate synchronously. The gears 30 meshing with the vertical toothed plate 28 are transmitted through the rotating shaft 29, causing the gears 30 in the first slide groove 22 to rotate synchronously. This drives the horizontal toothed plate 31 to move the protective plate 2 along the first slide groove 22 and the second slide groove 24, moving it away from above the hopper 14, thus exposing the internal spikes 18 and cutting blades 19. As the vertical toothed plate 28 continues to descend, the hook 33 drives the ton bag to fall synchronously. After the bottom of the ton bag contacts the spikes 18, it will be precisely pierced. At the same time, the cutting blades 19 around the bag form multi-directional cuts under the action of the bag's gravity, completely slicing the bag. The material flows out from the rupture under the action of gravity and falls into the hopper 14. After being collected by the funnel-shaped structure, it flows to the cross baffle 15. The grid structure of the cross baffle 15 performs preliminary filtration of the falling material, intercepting impurities such as ton bag fragments. The pure material falls in a dispersed manner through multiple discharge ports 16 and enters the discharge trough 13 formed by the lower end of the discharge hopper 14 and the U-shaped frame 1. Finally, it is directionally transported to the subsequent processing system to avoid material accumulation and blockage.
[0032] After the bag-breaking operation is completed, the telescopic rod 35 drives the vertical toothed plate 28 to rise and reset. Through gear 30, the horizontal toothed plate 31 slides in the opposite direction to the protective plate 2, causing the protective plate 2 to re-close the upper end of the hopper 14, isolating the spike 18 and the cutting blade 19. Simultaneously, the hook 33 lifts the empty ton bag, allowing the operator to remove the remaining bag, completing one work cycle. When the vertical toothed plate 28 descends to the position where the ton bag contacts the spike 18 and the cutting blade 19, the protective plate 2 slides completely away from the hopper 14, not obstructing the bag-breaking operation. When the vertical toothed plate 28 rises and resets, i.e., the ton bag detaches from the bag-breaking component, the protective plate 2 slides back to the upper end of the hopper 14, completing the sealing and isolation. By adjusting the module, number of teeth, and tooth density of the gear 30, the stroke of both is kept in a fixed ratio, ensuring perfect matching of the action rhythm.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
