Description

Technical Field

[0001] This invention relates to the field of feed processing, specifically to a processing system for silage. Background Technology

[0002] In the prior art, such as the preparation method of green foxtail silage disclosed in patent publication number CN106107061B or the processing method of silage disclosed in patent publication number CN106615676B, the processing of silage first involves chopping the raw materials into the required size, then dehydrating them, and after dehydration, mixing them with the prepared fermentation liquid. After mixing, the feed is either stored in a cellar or sealed in bags.

[0003] Among them, bagged silage has the advantages of small footprint and easy access, making it especially popular among small farms.

[0004] When bagging silage, the mixed feed should first be compacted as much as possible to squeeze out the air. The compacted silage is then placed into bags, and the bags are then sealed tightly. To prevent problems such as decreased silage quality and reduced shelf life caused by air entering the bags, workers need to spend considerable effort and time sealing the bags. Summary of the Invention

[0005] The purpose of this invention is to address the above problems by providing a processing system for silage that can seal the bag opening after the silage is bagged.

[0006] To achieve the above objectives, the present invention employs a processing system for silage: it includes a discharge pipe connected to the discharge port of a pressing device. Before bagging, packaging bags are fitted onto the discharge pipe. A transfer mechanism is provided on the discharge side of the discharge pipe. The transfer mechanism includes a base, a rotating part at the upper end of the base, and a carrying plate at the upper end of the rotating part. A sealing mechanism is provided on one side of the rotation path of the rotating part. The sealing mechanism includes a sealing film mechanism and a cutting mechanism. The sealing film mechanism includes rollers spaced vertically and a vertically moving lifting seat. A clamping mechanism is provided on the lifting seat, which pulls the sealing film on the rollers to cover the bag opening. Subsequently, the worker seals the bag opening with a sealing cap. The cutting mechanism includes a cutter holder that moves along the axial direction of the rollers, and a cutting blade is provided on the cutter holder. The cutting blade cuts off the excess sealing film, thereby completing the bag sealing.

[0007] Furthermore, to further improve the level of automation, the sealing mechanism also includes a sealing cap pushing mechanism, which includes a shelf and a horizontal pushing mechanism connected to a push plate. The horizontal pushing mechanism pushes the sealing cap on the shelf toward the packaging bag to automatically complete the sealing.

[0008] Furthermore, the push plate is equipped with a suction cup to prevent the sealing cap from falling off the push plate during the pushing process.

[0009] Furthermore, since the compacted feed is relatively heavy, in order to prevent the packaging bag and the axis of the carrier plate from misaligning during the rotation of the carrier plate, which would prevent the sealing cap from sealing the bag opening, a crossbeam is arranged on the side of the carrier plate, and a baffle is provided on the upper end of the crossbeam. The baffle abuts against the side wall of the packaging bag to ensure that the packaging bag and the carrier plate rotate synchronously.

[0010] Furthermore, when the compacted feed is pushed into the packaging bag, in order to prevent the packaging bag from falling off the discharge pipe, a clamping plate is provided on the outside of the discharge pipe. The clamping plate moves radially along the discharge pipe under the push of the clamping drive mechanism to fix the opening of the packaging bag on the outside of the discharge pipe.

[0011] Furthermore, the clamping plate is provided with matching protrusions and grooves on one side of the discharge pipe and on the outer wall of the discharge pipe to increase friction and ensure that the bag opening will not slip off the discharge pipe.

[0012] Furthermore, in order to ensure that the rotating part can rotate with the packaging bag so that the bag opening faces the sealing mechanism, an extension is provided at the lower end of the rotating part, and the extension slides along the length direction of the base.

[0013] Furthermore, although compacted silage is very dense, it may become loose after being left for a long time, resulting in poor sealing and allowing air to enter the packaging bag, thus reducing the quality of the feed. To address this, it also includes an inner ring, which is placed on the discharge pipe before bagging. The packaging bag is fitted over the outer side of the inner ring, and the outer diameter of the inner ring is matched with the inner diameter of the sealing cap. The packaging bag is held between the inner ring and the sealing cap to ensure the airtightness of the bag opening.

[0014] Furthermore, to prevent the inner ring from falling off the discharge pipe when the silage is bagged, the end face of the inner ring and the end face of the discharge pipe are provided with matching positioning holes and positioning posts.

[0015] The beneficial effects of this invention are as follows: the pressed silage is pushed from the discharge pipe into a packaging bag pre-fitted onto the discharge pipe. Then, driven by the rotating part, the carrier plate rotates the bag opening from the discharge pipe side to the sealing mechanism side. After the bag opening is adjusted, the clamping mechanism pulls the sealing film vertically so that the sealing film covers the bag opening. Then, the sealing cap moves toward the packaging bag to seal the bag opening with the sealing film, thereby reducing the labor intensity of workers, improving work efficiency, ensuring the sealing quality of the bag opening, and extending the shelf life of the silage.

[0023] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0024] Example 1: As Figures 1-5As shown, the specific structure of this embodiment is as follows: It includes a discharge pipe 1 installed at the discharge port of the pressing equipment. A transfer mechanism is provided on the discharge side of the discharge pipe 1. The transfer mechanism includes a base 2. A rotating part 3 is provided at the upper end of the base 2. The rotating part 3 can be a motor-driven turntable or a hydraulic turntable, etc. The rotation axis of the rotating part 3 is vertically arranged. An extension part 21 is provided at the lower end of the rotating part 3. The extension part 21 extends into a sliding groove at the upper end of the base 2. The sliding groove is arranged along the length direction of the base 2. The base 2 is provided with a drive mechanism for driving the extension part 21 to move along the sliding groove. The drive mechanism can be an electric push rod, etc. In this embodiment, the drive mechanism of the line-driven mechanism adopts an adjusting screw threadedly connected to the extension 21. The adjusting screw rotates under the drive of the motor. At the same time, a transverse guide post passing through the extension is provided in the base 2. The upper end of the rotating part 3 is provided with a carrying plate 4. Crossbeams 15 are arranged on both sides of the carrying plate 4 along its length. Baffles 16 are provided on the upper end of the crossbeams 15. The distance between the baffles 16 is adapted to the width of the silage pile after compression. A sealing mechanism 5 is provided on one side of the rotation path of the rotating part 3. In this embodiment, the discharge pipe 1, the transfer mechanism and the sealing mechanism 5 are arranged in a triangle.

[0025] The sealing mechanism 5 includes a sealing mechanism and a cutting mechanism. The sealing mechanism includes rollers 6 and lifting seats 7 arranged at intervals. The rolled sealing film is pre-fitted onto the outside of the rollers 6. The rollers 6 are arranged horizontally. There are two lifting seats 7, which are located at both ends of the axis of the rollers 6. The lifting seats 7 are equipped with a clamping mechanism 8, which can be pneumatic grippers or the like. The lifting seats 7 move vertically under the action of the vertical drive mechanism. In this embodiment, the lifting seats 7 are threadedly connected to the vertical lead screw 24. The upper and lower ends of the vertical lead screw 24 are connected to bearing seats. The bearing seats at the upper and lower ends are respectively installed on the upper and lower sides of the frame 25. The upper end of the vertical lead screw 24 is connected to the clamping motor on the frame 25. The side end of the frame is equipped with a T-shaped slide rail. The lifting seats 7 are equipped with a T-shaped groove that matches the T-shaped slide rail.

[0026] The cutting mechanism includes a cutter holder 9 that moves along the axial direction of the roller 6, and a cutting blade 10 is provided on the cutter holder 9. The cutter holder 9 is connected to a transverse lead screw on the frame 25.

[0027] A clamping plate 17 is provided on the outer side of the discharge pipe 1. The clamping plate 17 moves radially along the discharge pipe 1 under the push of the clamping drive mechanism 18. The clamping drive mechanism 18 can be a cylinder, an electric push rod, etc. The clamping plate 17 has a protrusion 19 on one side of the discharge pipe 1, and the outer wall of the discharge pipe 1 has a groove 20 that matches the position, number, and size of the protrusion 19.

[0028] Specific work process: The staff first open the opening of the packaging bag and put it over the outside of the discharge pipe 1. Figure 1 , Figure 3The dotted line in the diagram represents a packaging bag. The size of the packaging bag is adapted to the size of the discharge pipe 1, that is, it is adapted to the silage pile. Then, the clamping plate 17 moves towards the discharge pipe 1 under the push of the clamping drive mechanism 18 to fix the packaging bag on the discharge pipe 1. At this time, the length direction of the carrying plate 4 is collinear with the axis of the discharge pipe.

[0029] The compressed silage is pushed into the packaging bag along the discharge pipe 1 until it reaches the end of the packaging bag. After the silage is filled, the clamping plate 17 releases the packaging bag, and then the rotating part 3 starts to work, causing the bag opening to rotate to the sealing mechanism. At this time, the bag opening is located below the roller 6. Before the rotating part 3 starts working, the carrying plate 4 moves to the far end of the discharge pipe 1 to prevent the silage from hitting the discharge pipe 1.

[0030] After the packaging bag rotates, the clamping mechanism 8 pulls the sealing film downwards. During this movement, it contacts the bag opening and bends the excess portion. The lower edge of the sealing film extends beyond the bottom surface of the packaging bag to allow for extra space, and the width of the sealing film must also exceed the width of the packaging bag. The worker then places the sealing cap 26 on the side of the bag opening, with the sealing film positioned between the packaging bag and the sealing cap 26. The clamping mechanism then releases the sealing film and rises back to its original position. After resetting, the two clamping fingers of the clamping mechanism do not close but open, allowing the sealing film to pass between them. This ensures that the sealing film at the top of the packaging bag moves with the sealing cap during the subsequent sealing process. The worker then pushes the sealing cap 26 towards the tail end of the packaging bag until it reaches the silage pile, sealing the bag opening. Because the silage is compacted, the sealing cap, along with the sealing film, fits tightly against the outer wall of the packaging bag. After the sealing cap 26 is closed, the cutting blade 10 moves along the width of the packaging bag to cut the sealing film between the sealing cap 26 and the clamping mechanism 8. At this time, the clamping fingers of the clamping mechanism 8 close to hold the thread end of the sealing film.

[0031] When the silage needs to be taken out, simply remove the sealing cap 26 by force. A handle or similar device can be installed on the outside of the sealing cap 26 to facilitate the application of force by the staff.

[0032] Example 2, as Figures 1-3 As shown, other structures and working processes in this embodiment can be referred to in Embodiment 1. However, in order to further reduce the labor intensity of operators, the sealing mechanism 5 in this embodiment also includes a sealing cap pushing mechanism. The sealing cap pushing mechanism includes a support frame 11, which includes a tray for placing the sealing cap and a vertical plate located at the upper end of the tray. A horizontal pushing mechanism 12 is provided on the vertical plate of the support frame 11. The horizontal pushing mechanism 12 can be a cylinder, hydraulic cylinder, etc. The horizontal pushing mechanism 12 is connected to the pushing plate 13. A suction cup 14 is provided on the pushing plate 13.

[0033] The specific working process is as follows: the staff first place the sealing cap 26 upright on the upper part of the tray of the shelf 11. After the sealing film is moved, the horizontal pushing mechanism 12 drives the sealing cap 26 to move towards the packaging bag to complete the sealing of the packaging bag.

[0034] Example 3, as Figure 6 As shown, other structures and working processes of this embodiment can be referred to in Embodiment 1. This embodiment also includes an inner ring 22 with open ends on both sides of the axis. The inner ring 22 has a positioning hole on the end face that contacts the discharge pipe 1, and a positioning post 23 is provided on the end face of the discharge pipe 1. The outer diameter of the inner ring 22 is adapted to the inner diameter of the sealing cover, and the inner diameter of the inner ring 22 is not less than the inner diameter of the discharge pipe 1.

[0035] Specific working process: Before putting the sealing bag onto the discharge pipe 1, install the inner ring 22 onto the discharge pipe 1 so that the positioning post 23 is inserted into the positioning hole. Then, the worker puts the packaging bag onto the discharge pipe 1. Figure 6 The dotted line in the diagram represents the packaging bag. The clamping plate 17 then moves to secure the packaging bag to the discharge pipe 1 and the inner ring 22. After the silage is bagged, the clamping plate 17 releases the packaging bag. Because the diameter of the packaging bag matches the silage pile, the inner ring is held between the silage and the packaging bag. Then, the carrying plate 4 moves away from the discharge pipe 1, separating the inner ring 22 from the discharge pipe 1. After the sealing film completely covers the bag opening, the sealing cap 26 closes the bag opening. At this time, the sealing film is held between the inner ring 22 and the sealing cap 26. Both the inner ring 22 and the sealing cap 26 are made of rigid material. After the sealing cap 26 is fastened, the edge of the inner ring extends beyond the edge of the sealing cap 26, making it convenient for workers to hold the inner ring 22 and the sealing cap 26 separately when opening the sealing cap 26.
