Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, specifically relating to a seed bag breaking machine with bag dust separation function. Background Technology

[0002] Seeds are typically packaged in woven or paper bags during processing, storage, and transportation. In subsequent seed treatment or sowing stages, these bags need to be opened to retrieve the seeds. Traditionally, this involves manually cutting open the bags with a knife, which is inefficient, labor-intensive, and can easily cause injury to operators.

[0003] To address these issues, automated bag-breaking equipment has emerged. This equipment uses blades to cut packaging bags on a conveyor belt, achieving automatic bag breaking.

[0004] However, the bag-breaking blades of such devices usually act directly on the middle or bottom of the bag, which can easily scratch or crush the seeds inside during the cutting process, resulting in seed loss and quality decline. In addition, the surface and inside of the packaging bag are often covered with a lot of dust and impurities. After the bag is broken, this dust will mix with the seeds, which not only pollutes the working environment, but also requires additional dust removal processes, increasing the complexity and cost of the production process. Summary of the Invention

[0017] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0018] like Figures 1-6 As shown, a seed bag breaking machine with bag dust separation function is applied to a packaging bag. The packaging bag includes a packaging bag body 10. Both the upper and lower sides of the packaging bag body 10 are provided with edge portions 15. Two hanging ropes 16 are fixedly connected to the upper side of the edge portion 15 on the upper side.

[0019] like Figures 1-6 As shown, a seed bag breaking machine with bag dust separation function includes an upper housing 1, a bag breaking knife 4, a dust separation mechanism, a conveying mechanism 2, and multiple bag hanging devices 3; The bag-breaking knife 4 is fixedly connected to the upper housing 1 and is used to break the packaging bag body 10 that moves inside the upper housing 1, so that the seeds inside the packaging bag body 10 can be discharged.

[0020] Specifically, the bag-breaking knife 4 can be a knife installed inside the upper housing 1. When the main body of the packaging bag 10 passes through the bag-breaking knife 4, the main body of the packaging bag 10 can be cut by the bag-breaking knife 4.

[0021] The dust separation mechanism is fixedly connected to the lower half of the upper housing 1 and is used to separate the seeds and dust discharged from the packaging bag body 10.

[0022] like Figures 1-2 As shown, the dust separation mechanism includes a seed hopper 6, a dust hopper 7, and a fan 5. The seed hopper 6 and the dust hopper 7 are both fixedly connected to the lower side of the upper housing 1, and the fan 5 is fixedly connected to one side of the upper housing 1. At this time, during the falling of seeds and dust, the fan 5 is activated to release airflow, which can be used to separate the seeds and dust. The seeds fall directly into the interior of the seed hopper 6 under the action of gravity, and the dust is blown towards the dust hopper 7 under the action of airflow, and then discharged through the dust hopper 7.

[0023] In some further embodiments, a hopper 8 is fixedly connected to the inner side of the upper housing 1, and a discharge guide net 9 located above the seed discharge hopper 6 is fixedly connected to the lower side of the hopper 8. Seeds discharged from the packaging bag body 10 will fall into the hopper 8 under the action of gravity, and then be discharged into the seed discharge hopper 6 through the discharge guide net 9.

[0024] The material guide mesh cover 9 has filter holes on both sides for airflow and to allow dust to be discharged through the filter holes.

[0025] Furthermore, the cross-sectional shape of the feed guide net 9 is preferably a broken line shape, which can extend the path of the seeds when they fall, increase the duration of the seeds' fall, and effectively reduce the impact force of the falling seeds, thus reducing the damage to the seeds.

[0026] The conveying mechanism 2 is fixedly connected to the inner side of the upper housing 1, and both ends of the conveying mechanism 2 are located on the outer side of the upper housing 1. like Figures 1-2 As shown, the conveying mechanism 2 includes a frame body 11 fixedly connected to the upper housing 1. Two drive wheels 12 are rotatably connected to the frame body 11. A drive belt 13 is driven to the outer side of the two drive wheels 12. A drive motor 14 is fixedly connected to the frame body 11. The output end of the drive motor 14 is driven to one of the drive wheels 12. By starting the drive motor 14, the drive wheel 12 can be driven to rotate, thereby driving the drive belt 13 to move.

[0027] Specifically, the drive wheel 12 can be a sprocket or a drive metal wheel, and the drive belt 13 can be a chain or a drive metal belt. In this technical solution, the drive wheel 12 is preferably a sprocket, and the drive belt 13 is preferably a chain.

[0028] Multiple bag lifting devices 3 are installed on the transmission belt 13 of the conveying mechanism 2, and the main body of the packaging bag 10 can be installed on the bag lifting device 3. The conveying mechanism 2 drives the bag lifting device 3 and the main body of the packaging bag 10 to move.

[0029] like Figures 2-3 As shown, the bag lifting device 3 includes a lifting frame 18. The upper side of the lifting frame 18 is connected to the transmission belt 13 via two connecting ropes 17. A C-shaped frame 19 is fixedly connected to the lower side of the lifting frame 18. A top support 20 is fixedly connected to the C-shaped frame 19. A top lifting device is fixedly connected to the lower side of the top support 20 for fixing the lifting rope 16 on the upper part of the packaging bag body 10. The top lifting device is preferably a hook 21 fixedly connected to the lower side of the top support 20.

[0030] Rotary drive units are installed on both sides of the C-shaped frame 19. Side brackets 33 are fixedly connected to both rotary drive units. Electric clamps are fixedly connected to both the upper and lower ends of the side brackets 33. In use, the hanging rope 16 of the packaging bag is hung on the hook 21, and then the electric clamp is used to clamp the upper and lower edges 15 of the main body 10 of the packaging bag. Then, the conveying mechanism 2 drives the main body 10 of the packaging bag to move. When the main body 10 of the packaging bag moves to the bag-breaking knife 4, the bag-breaking knife 4 can break the upper edge 15, so that the upper part of the edge 15 is separated from the main body 10 of the packaging bag. Then, the rotary drive group is rotated to drive the main body 10 of the packaging bag to rotate, so that the opening of the edge 15 is rotated to the bottom, thus completing the discharge of the seeds inside the main body 10 of the packaging bag. Since the opening of the bag-breaking knife 4 is located at the upper edge 15 of the packaging bag, the seeds will always be separated from the upper edge 15 under the action of gravity, thereby reducing the damage to the seeds during the bag-breaking process.

[0031] like Figures 3-4As shown, the rotary drive assembly includes an electric telescopic rod 22 and a rotating rod body. The rotating rod body is rotatably connected to the C-shaped frame 19. One end of the rotating rod body is fixedly connected to the side support 33. A rotating plate 25 is fixedly connected to one side of the rotating rod body. A transmission rod 24 is fixedly connected to one end of the rotating plate 25. The electric telescopic rod 22 is fixedly connected to one side of the C-shaped frame 19. The piston rod of the electric telescopic rod 22 is fixedly connected to a vertical rail 23. The vertical rail 23 and the transmission rod 24 are slidably connected. By activating the electric telescopic rod 22 to push the vertical rail 23 to move, the transmission rod 24 can be pushed to perform an arc-shaped movement, thereby driving the rotating plate 25 to rotate, thus realizing the rotation of the side support 33.

[0032] A guide groove 26 can also be fixedly connected to one side of the C-shaped frame 19. The transmission rod 24 and the guide groove 26 are slidably connected, thereby guiding the movement of the transmission rod 24.

[0033] Among them, such as Figure 3 and Figure 6 As shown, the electric clamp includes a side plate 27 fixedly connected to a side bracket 33. Two moving blocks 28 are slidably connected to the side plate 27. Each moving block 28 is fixedly connected to an L-shaped support arm 29. A clamping plate 30 is fixedly connected to the end of each L-shaped support arm 29. A left-hand and right-hand threaded rod 32 is rotatably connected to the side plate 27. The left-hand and right-hand threaded rod 32 has a left-hand threaded part and a right-hand threaded part on its outer side. The left-hand threaded part and the right-hand threaded part are respectively threaded to the two L-shaped support arms 29. A servo motor 31 is fixedly connected to the side plate 27. The output end of the servo motor 31 is connected to the left-hand and right-hand threaded rod 32 for transmission. By starting the servo motor 31, the left-hand and right-hand threaded rod 32 can be driven to rotate, thereby moving the clamping plate 30.

[0034] The method of using this technical solution is as follows: First, hang the hanging rope 16 of the packaging bag to be opened on the hook 21 of the top bracket 20, and at the same time start the upper and lower sets of electric clamps so that their clamping plates 30 clamp the upper and lower edges 15 of the packaging bag. After clamping is completed, start the drive motor 14, which drives the bag lifting device 3 and the packaging bag into the upper housing 1 through the drive wheel 12 and the drive belt 13.

[0035] When the packaging bag moves to the bag-breaking cutter 4, the cutter cuts the upper edge 15, separating its upper part from the bag body to form an outlet. At this time, the electric telescopic rod 22 of the rotary drive unit is activated, driving the rotating plate 25 to rotate via the vertical rail 23 and the transmission rod 24. This, in turn, causes the side support 33 and the electric clamp to rotate 180°, so that the opening end of the packaging bag faces downwards. The seeds inside the packaging bag fall under the influence of gravity.

[0036] The falling seeds and dust first fall into the collection hopper 8, and then slowly slide down along the zigzag discharge guide screen 9. During this process, the blower 5 is activated, and the air force blows the lighter dust through the filter holes on both sides of the discharge guide screen 9 towards the dust discharge hopper 7 for discharge, while the heavier seeds fall along the screen into the seed discharge hopper 6, thus achieving the separation of seeds and dust. After discharge, the empty bag is moved out of the upper housing 1 by the conveyor mechanism 2, the electric clamp is released, and one work cycle is completed.

[0037] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
