Description

Technical Field

[0001] This invention relates to the field of livestock breeding machinery technology, and in particular to a device for untying the ropes of square hay bales used in pastures. Background Technology

[0002] When feeding livestock on ranches, hay and concentrate feed need to be crushed and mixed. It is well known that the hay brought in by large ranches is mostly bundled with six nylon ropes. When hay is used as feed, nylon ropes are not allowed to be mixed into the feed, so the wrapping ropes must be removed. Currently, the wrapping ropes on large hay bales are cut off manually with a blade, and the ropes are pulled out one by one. Since each large bale generally weighs 200 to 350 kilograms, the process of moving and removing the ropes requires the cooperation of loaders and workers. The cooperation between people and machinery brings considerable safety hazards, and the high dust concentration in the workplace has a health impact on people's respiratory system. Large cattle farms require a large amount of hay per day, and removing the wrapping ropes increases the ranch's expenses.

[0003] Based on the above reasons, the present invention provides a device for untying the ropes of square hay bales used in pastures. Summary of the Invention

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figures 1-6 This invention provides a device for untying the ropes of square hay bales used in ranches, comprising:

[0032] Connecting frame 1, which is detachably connected to the loader;

[0033] The gripper includes an upper gripper tooth 2 and a lower gripper tooth 3. The upper gripper tooth 2 is rotatably connected to the top of the connecting frame 1, and the lower gripper tooth 3 is vertically fixed to the connecting frame 1. The upper gripper tooth 2 and the lower gripper tooth 3 are arranged correspondingly. A control component is installed on the connecting frame 1 to control the rotation of the upper gripper tooth 2.

[0034] The rope clamping mechanism has two sets of symmetrically arranged on the upper gripper teeth 2;

[0035] The rope cutting mechanism is installed on the lower gripper 3 and is located between the two rope clamping mechanisms.

[0036] Among them, the square straw bale 4 is held between the upper gripper 2 and the lower gripper 3.

[0037] When this invention is in operation, the device is connected to the loader via the connecting frame 1, and driven by the loader. The upper gripper 2 is opened by the control component, and the upper gripper 2 cooperates with the lower gripper 3 to grasp the square hay bale 4. The rope clamping mechanism is set on the upper gripper 2 to grasp the hay rope, and the rope cutting mechanism is set on the lower gripper 3 to cut the hay rope. After the rope cutting mechanism cuts, the loader control device flips, the control component controls the upper gripper 2 to open, the square hay bale 4 falls off, the rope clamping mechanism pulls out the hay rope, and finally the hay rope is put down.

[0038] This invention can automatically remove the ropes from large hay bales without manual cutting, and the ropes can be easily recycled after removal, reducing the intensity of manual labor.

[0039] The scheme is further optimized. The control components include a telescopic cylinder 5, which is set perpendicularly to the upper gripper 2 and the lower gripper 3. The bottom end of the telescopic cylinder 5 is connected to the connecting frame 1 through a mounting base. A connecting rod 6 is fixedly connected to the top of the upper gripper 2. A keyway is opened at one end of the connecting rod 6, and a mounting shaft is slidably connected in the keyway. The top end of the telescopic cylinder 5 is rotatably connected to the mounting shaft.

[0040] Further optimization of the scheme: the rope clamping mechanism includes several rope clamping components. The rope clamping components include a movable clamp 7 and a rope clamping base 8. The rope clamping base 8 is fixedly connected to the upper gripper tooth 2. The middle part of the movable clamp 7 is rotatably connected to the upper gripper tooth 2. The movable clamp 7 is correspondingly set with the rope clamping base 8. A rope clamping opening and closing drive component is installed on the upper gripper tooth 2. The movable clamp 7 is rotatably connected to the rope clamping opening and closing drive component.

[0041] Further optimization of the scheme: the rope clamping opening and closing drive assembly includes a rope clamping rod 9, which is horizontally mounted on the upper gripper tooth 2. The end of the movable clamp 7 is rotatably connected to the rope clamping rod 9. The end of the movable clamp 7 is fixedly connected to a rope clamping support ear 10. A rope clamping connecting arm 11 is rotatably connected to the rope clamping support ear 10. One end of the rope clamping connecting arm 11 is rotatably connected to the rope clamping rod 9. A first hydraulic cylinder 12 is rotatably connected to the upper gripper tooth 2. One end of the first hydraulic cylinder 12 is rotatably connected to the end of the rope clamping connecting arm 11 near the rope clamping rod 9.

[0042] The design is further optimized by fixing a mounting plate 13 to the rope clamping base 8, fixing a tension spring 15 to the mounting plate 13, and slidingly connecting a movable support plate 14 to the rope clamping base 8. The movable support plate 14 is positioned parallel to the mounting plate 13 and faces it directly. One end of the tension spring 15 is fixedly connected to the movable support plate 14, and the movable clamp 7 is correspondingly positioned to the movable support plate 14. The arrangement of the spring and the movable support plate 14 ensures the stability of the grip and facilitates subsequent release.

[0043] Further optimizing the design, the rope-cutting mechanism includes several rope-cutting assemblies mounted on the lower gripper teeth 3. Each rope-cutting assembly includes a fixed blade 16 and a movable blade 17. The fixed blade 16 is fixedly connected to the lower gripper teeth 3, and the middle of the movable blade 17 is rotatably connected to the lower gripper teeth 3. A rope-cutting opening and closing drive assembly is mounted on the lower gripper teeth 3, and all movable blades 17 are rotatably connected to this drive assembly. Both the fixed blade 16 and the movable blade 17 are configured with circular sawtooth shapes, and the movable blades 17 are staggered from the fixed blades 16 for cutting the bundled rope.

[0044] The scheme is further optimized. The rope cutting opening and closing drive assembly includes a rope cutting rod 18 horizontally set on the lower gripper 3. Several movable blades 17 are rotatably connected to the rope cutting rod 18. One end of the lower gripper 3 is fixedly connected to a rope cutting support ear 19. A rope cutting connecting arm 20 is rotatably connected to the rope cutting support ear 19. One end of the rope cutting connecting arm 20 is rotatably connected to one end of the rope cutting rod 18. A second hydraulic cylinder 21 is rotatably connected to the lower gripper 3. The output end of the second hydraulic cylinder 21 is rotatably connected to the end of the rope cutting connecting arm 20 near the rope cutting rod 18.

[0045] In this embodiment, the telescopic cylinder 5 drives the connecting rod 6 to pull the upper gripper 2 to rotate and grab the square hay bale 4. The first hydraulic cylinder 12 controls the movable clamp 7 to rotate, which, together with the rope clamping base 8, clamps the hay rope. The second hydraulic cylinder 21 pushes the rope cutting rod 18 to move, which drives the movable blade 17 to rotate. The movable blade 17 and the fixed blade 16 work together to cut the hay rope. Then, the telescopic cylinder 5 drives the upper gripper 2 to open, the connecting frame 1 flips, and the hay falls off the device. At the same time, the rope clamping base 8 and the movable clamp 7 work together to pull out the hay rope. Then, the movable clamp 7 is released, the hay rope is lowered, and the rope removal work is completed.

[0046] The design was further optimized by serrulating the sides of both the fixed blade 16 and the movable blade 17. The inner side of the movable clamp 7 was also serrated.
