Description

Technical Field

[0001] This invention relates to the field of feed processing, specifically to an apparatus for preparing 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 silage preparation apparatus that can seal the bag opening after the silage is bagged.

[0006] To achieve the above objectives, the present invention provides a silage preparation device: it includes a discharge pipe connected to the discharge port of a pressing device. Before bagging, a packaging bag is placed on the discharge pipe. A temporary storage section with an open lower end is provided on one side of the discharge pipe. A limiting plate is movably installed at the lower edge of the temporary storage section. A sealing drive mechanism for pushing a sealing cap is provided on the temporary storage section. When the packaging bag containing silage moves below the temporary storage section, the sealing drive mechanism pushes the sealing cap towards the packaging bag to complete the sealing. To improve the sealing quality, a sealing film needs to be covered at the bag opening before sealing. For this purpose, a roller is provided on one side of the temporary storage section, and a clamping mechanism pulls the sealing film on the roller through the lower part of the temporary storage section. After sealing, a cutter head moves along the width direction of the sealing film. The cutter head is equipped with a cutting blade for cutting the sealing film. A transfer mechanism is provided on the discharge side of the discharge pipe, and the transfer mechanism moves between the discharge pipe and the temporary storage section.

[0007] Furthermore, to improve the level of automation, the side wall of the temporary storage section is connected to the storage section through the feed hole. The sealing caps are stacked vertically in the storage section. The side wall of the storage section is provided with a pusher for pushing the sealing caps. When the bottommost sealing cap in the storage section is pushed into the temporary storage section and the pusher retracts from the storage section, the remaining sealing caps are automatically replenished under the action of gravity.

[0008] Furthermore, the transfer mechanism includes a carrying plate that slides on the upper end of the base to move the packaging bag from below the discharge pipe to below the temporary storage section.

[0009] Furthermore, to prevent the packaging bag from tipping over during the movement of the carrier plate, a baffle is provided along the edge of the upper part of the carrier plate.

[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 and reduce the labor intensity of the workers, a clamping plate is provided on the outer side of the discharge pipe. The clamping plate moves radially along the discharge pipe under the push of the clamping drive mechanism. The workers put the bag opening on the outer wall of the discharge pipe, and then the clamping plate fixes the packaging bag on 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 drive the clamping mechanism to move, the clamping mechanism is mounted on a sliding seat, and the support is provided with a guide post passing through the sliding seat and a clamping drive screw, one end of which is connected to a clamping drive motor on the support.

[0013] Furthermore, after the clamping mechanism pulls the sealing film to cover the bag opening, the sealing cap is closed on the packaging bag. In order to cut the sealing film and at the same time ensure that the sealing film will not fall off the clamping mechanism, the knife holder is set between the support and the temporary storage part. The cutting drive screw and the guide rail pass through the knife holder. One end of the cutting drive screw is connected to the cutting drive motor on the support column.

[0014] 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. It also includes an inner ring, which is placed on the discharge pipe before bagging. The outer diameter of the inner ring is adapted to the inner diameter of the sealing cap, and the packaging bag is held between the inner ring and the sealing cap to ensure the sealing of the bag opening.

[0015] The beneficial effects of this invention are as follows: The compressed silage is pushed from the discharge pipe into a pre-fitted packaging bag. A transfer mechanism then carries the packaging bag from the discharge pipe to the temporary storage area. After the transfer, a clamping mechanism pulls the sealing film laterally, covering the bag opening. Subsequently, the sealing cap, driven by a sealing drive mechanism, moves from the temporary storage area to the packaging bag, sealing the bag opening with the sealing film. This reduces the labor intensity of workers, improves work efficiency, ensures the quality of the bag seal, and extends the shelf life of the silage. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] Example 1: As Figures 1-3As 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. In this embodiment, the discharge pipe 1 is arranged vertically. A temporary storage part 2 is provided on one side of the discharge pipe 1. In this embodiment, the temporary storage part 2 is a tubular structure whose inner wall is adapted to the inner diameter of the sealing cover 4, and the lower end of the temporary storage part 2 is open. The lower edge of the temporary storage part 2 is connected to the limiting plate 3 by a torsion spring. Alternatively, a linear pushing mechanism such as a cylinder can be provided on the temporary storage part 2 to drive the limiting plate 3 to move laterally. The limiting plate 3 is normally placed horizontally, and the limiting plates 3 are arranged in pairs. A sealing drive mechanism 5 is provided at the upper end of the temporary storage part 2. The sealing drive mechanism 5 can be a cylinder, an electric push rod, etc. The piston rod of the sealing drive mechanism 5 extends into the temporary storage part 2 and is connected to the push plate. A vacuum suction cup, etc., can be provided at the lower end of the push plate.

[0023] A roller 6 is provided on one side of the temporary storage section 2. In this embodiment, the axis of the roller 6 is in the same direction as the direction of movement of the packaging bag. The clamping mechanism 7 pulls the sealing film on the roller 6 through the bottom of the temporary storage section 2 under the action of the cylinder and other driving mechanism. In this embodiment, the clamping mechanism 7 is provided on the sliding seat 19. There are two sliding seats 19 and they are respectively placed at both ends of the roller 6. The support 20 is provided with a guide post 21 passing through the sliding seat 19 and a clamping drive screw 22. One end of the clamping drive screw 22 is connected to the clamping drive motor 23 on the support 20.

[0024] A cutter holder 8 is provided between the support 20 and the temporary storage section 2. The cutting drive screw 24 and the guide rail 25 pass through the cutter holder 8. The cutting drive screw 24 and the guide rail 25 are arranged along the axial direction of the roller 6. One end of the cutting drive screw 24 is connected to the cutting drive motor 27 on the support column 26. A cutting knife 9 for cutting the sealing film is provided on the cutter holder 8. A transfer mechanism is provided on the discharge side of the discharge pipe 1. The transfer mechanism moves between the discharge pipe 1 and the temporary storage section 2.

[0025] A clamping plate 16 is arranged radially opposite to the outer side of the discharge pipe 1. The clamping plate 16 moves radially along the discharge pipe 1 under the push of the clamping drive mechanism 17. The clamping drive mechanism 17 can be a cylinder, an electric push rod, etc. The clamping plate 16 has a protrusion 18 on one side of the discharge pipe 1. The outer wall of the discharge pipe 1 has a groove that matches the position, number, and size of the protrusion 18.

[0026] 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 2 The 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 16 moves towards the discharge pipe 1 under the push of the clamping drive mechanism 17 to fix the packaging bag on the discharge pipe 1.

[0027] The compressed silage is pushed into the packaging bag along the discharge pipe 1 until it reaches the end of the bag. After the silage is filled, the clamping plate 16 releases the packaging bag, at which point the bag is caught by the transfer mechanism and carried to the bottom of the temporary storage section 2. Figure 1 The arrows in the diagram indicate the direction of movement of the transfer mechanism.

[0028] After the packaging bag rotates, the clamping mechanism 7 pulls the sealing film on the roller 6 to move laterally. During the movement, it contacts the opening of the packaging bag, bending the excess portion of the opening so that the outer diameter of the sealing film exceeds the opening of the packaging bag. Then, the worker places the sealing cap 4 on the side of the bag opening, with the sealing film positioned between the packaging bag and the sealing cap 4. The clamping mechanism 7 then releases the sealing film and retracts to its original position. After resetting, the two gripping fingers of the clamping mechanism 7 do not close but instead open, allowing the sealing film to pass between the two fingers. This ensures that the sealing film on the roller 6 moves with the sealing cap 4 during the subsequent sealing process. The worker then pushes the sealing cap 4 towards the tail end of the packaging bag to close the opening. Because the silage is compacted, the sealing cap 4, along with the sealing film, fits tightly against the outer wall of the packaging bag. After the sealing cap 4 is closed, the cutting blade 9 moves along the width of the packaging bag to cut the sealing film between the sealing cap 4 and the clamping mechanism 7. At this time, the clamping fingers of the clamping mechanism 7 close to hold the thread end of the sealing film.

[0029] When the silage needs to be taken out, simply remove the sealing cap 4 by force. A handle or similar device can be installed on the outside of the sealing cap 4 to facilitate the application of force by the staff.

[0030] Example 2, as Figures 2-3 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 in this embodiment, the side wall of the temporary storage section 2 is connected to the storage section 11 through the feed hole 10. The sealing cover 4 is stacked vertically in the storage section 11. The side wall of the storage section 11 is provided with a pushing section 12 for pushing the sealing cover 4. The pushing section 12 moves under the drive of a cylinder or the like. When the pushing section 12 enters the storage section 11, the outer diameter of the pushing section 12 can block the other sealing covers 4 from falling.

[0031] Specific working process: The pushing part 12 pushes the lower sealing cover 4 in the storage part 11 into the temporary storage part 2 through the feed hole 10. Then the pushing part 12 retracts and resets. After the pushing part 12 exits from the storage part 11, the remaining sealing covers 4 fall down to fill the gap.

[0032] Example 3, as Figures 1-2As shown, other structures and working processes in this embodiment can be referred to the above embodiments. The transfer mechanism includes a carrying plate 13, which is connected to a slide rail on the base 14. A cylinder and a motor-driven screw drive mechanism are provided on the base 14. The drive mechanism is connected to the carrying plate 13. A baffle 15 is provided on the upper end of the carrying plate 13 along its edge. The baffles 15 at both ends of the moving path of the carrying plate 13 are higher, while the baffles 15 on both sides of the moving path of the carrying plate 13 are lower, so as to facilitate the staff to remove the sealed packaging bag from the carrying plate 13.

[0033] Example 4, as Figure 4 As shown, other structures and working processes in this embodiment can be referred to the above embodiments. In this embodiment, an inner ring 28 is used. In order to use the inner ring 28, an insert post can be set at the lower end of the discharge pipe 1. A driving mechanism for driving the insert post to move vertically is set inside the pipe wall of the discharge pipe 1. A positioning hole that fits tightly with the insert post is set on the upper end face of the inner ring. When the inner ring 28 is placed at the lower end of the discharge pipe 1, the insert post extends into the positioning hole to achieve a temporary connection between the inner ring 28 and the discharge pipe 1. When silage is loaded, the insert post separates from the positioning hole. Alternatively, an electromagnet or permanent magnet can be set at the lower end of the discharge pipe 1. A magnetic attraction part is set at the upper end of the inner ring 28. When the inner ring 28 is pushed to be coaxial with the discharge pipe 1, the inner ring 28 is attracted to the lower end of the discharge pipe 1. The outer diameter of the inner ring 28 is adapted to the inner diameter of the sealing cover 4.

[0034] Specific working process: Before putting the sealing bag onto the discharge pipe 1, the inner ring 28 is installed on the discharge pipe 1. Then, the worker puts the packaging bag onto the discharge pipe 1 and the inner ring 28. Figure 4 The dotted line in the diagram represents the packaging bag. The clamping plate 16 then moves to secure the packaging bag to the discharge pipe 1 and the inner ring 28. After the silage is bagged, the clamping plate 16 releases the packaging bag. Because the diameter of the packaging bag matches the silage pile, the inner ring is tightly secured between the silage and the packaging bag. The transfer mechanism then moves the packaging bag along with the inner ring 28 downwards towards the temporary storage section 2. During this movement, a lateral force is generated, causing the inner ring 28 to separate from the discharge pipe 1. After the sealing film completely covers the bag opening, the sealing cap 4 closes the bag opening. At this time, the sealing film is secured between the inner ring 28 and the sealing cap 4. Both the inner ring 28 and the sealing cap 4 are made of rigid material. After the sealing cap 4 is closed, the edge of the inner ring 28 extends beyond the edge of the sealing cap 4, allowing workers to easily grasp the sealing cap 4 and the inner ring 28 when opening the sealing cap 4.
