Description

Technical Field

[0001] This invention relates to the field of seedling pot production technology, specifically an automated production line for small-diameter-to-depth seedling pots. Background Technology

[0002] Small diameter-to-depth seedling pots are generally made of soft plastic. Before preparing for seedling cultivation, the soft plastic pots need to be filled with substrate soil, and holes need to be made on the upper surface of the substrate soil to facilitate the planting of rootstock seedlings. However, at present, all production links of small diameter-to-depth container seedling cultivation are basically completed manually, which is labor-intensive and has low production efficiency.

[0003] If an automated production line is used to produce small-diameter-depth seedling pots, the efficiency of small-diameter-depth container seedling cultivation can be significantly improved, and the intensity of manual labor can be reduced. Currently, production line solutions related to container seedling cultivation include vegetable seedling sowing production lines. This technical solution is a production line designed with vegetable seedling sowing as the overall function. This production line includes a soil-laying device, a soil-sweeping device, a hole-pressing device, a sowing device, and a soil-covering device, which are used to sequentially complete the soil-laying, soil-sweeping, hole-pressing, sowing, and soil-covering processes in the containers, in conjunction with the production line. However, for small-diameter-depth container seedling production lines, due to the differences in container types, the current seedling production line cannot be applied. Furthermore, the current vegetable seedling production lines and their application in small-diameter-depth container seedling cultivation have the following problems:

[0004] (1) In the existing vegetable seedling production line, the soil spreading device and the soil sweeping device are two independent units. After the soil spreading of the container is completed, the soil sweeping is carried out, and after the soil sweeping is carried out, the fallen soil is cleaned up. This will lead to an increase in the length of the production line and an inability to recycle the substrate soil in a timely manner.

[0005] (2) Because the small diameter-to-depth container seedling raising uses soft plastic pots, which cannot be placed stably, the soft plastic pots cannot be directly laid on the production line. The seedling pots need to be fixed before being transported to the production line for conveying. This will also cause gaps between containers, which cannot be well adapted to the current roller pressing method and cannot be directly applied to the current roller pressing device. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an automated production line for small diameter-to-depth seedling pots, which addresses the above-mentioned shortcomings. The present invention adopts an automated production line to realize the substrate filling, watering and hole pressing production of seedling pots. The whole process is automated, which can reduce labor intensity and improve production efficiency.

[0007] To solve the above technical problems, the present invention adopts the following technical solution:

[0008] An automated production line for small diameter-to-depth seedling pots includes a conveyor line, and a substrate filling device, a spraying device, and a hole pressing device arranged sequentially along the conveyor line's transmission direction.

[0009] The conveyor line is used to transport seedling frames along the transmission direction. The seedling frames are used to support and fix multiple seedling pots, and all seedling pots are neatly arranged inside the seedling frames.

[0010] The substrate filling device is used to fill all the seedling pots in the seedling frame with substrate soil and to recycle the excess substrate soil in the seedling pots.

[0011] The spraying device is used to spray water onto all the seedling pots in the seedling frame;

[0012] The caving device is used to create cavities on the upper surface of the substrate soil in each seedling pot;

[0013] The seedling frame is equipped with a structure for stacking and forklift operation, and multiple seedling frames can be stacked vertically. After the filling, watering, pressing and transportation operations are completed, all the seedling pots in the seedling frame can be unloaded downwards.

[0014] Furthermore, the conveyor line includes a belt conveyor mechanism and a roller conveyor mechanism. The output end of the belt conveyor mechanism is connected to the input end of the roller conveyor mechanism. The matrix filling device is disposed on the belt conveyor mechanism. The spraying device and the cavitation device are sequentially disposed on the roller conveyor mechanism along the conveying direction.

[0015] Furthermore, the seedling frame includes a frame body, partitions, a flipping mechanism, and a cover plate. Multiple horizontally and vertically intersecting partitions are evenly arranged inside the frame body, and all partitions divide the internal space of the frame body into multiple placement areas. The cover plate is detachably installed on the top of the frame body, and multiple funnel-shaped inlets are opened on the cover plate to facilitate the filling of substrate. A flipping mechanism is arranged below the partitions inside the frame body. The flipping mechanism includes a flipping plate located at the bottom of each placement area. The flipping mechanism is used to drive all flipping plates to rotate in a vertical plane to switch between a horizontal state and a vertical state, thereby closing or opening the lower surface of the placement area.

[0016] The bottom of the frame and the top of the cover plate are both provided with connecting structures, which are used to connect two adjacent seedling frames in the vertical direction.

[0017] Furthermore, the flip-plate mechanism includes a flip plate, a connecting rod, an operating rod, and a locking mechanism. Rectangular openings are provided on both the left and right sides of the frame below the partition. A connecting rod is horizontally arranged on both the left and right sides of the frame. The front and rear ends of all flip plates in the same column are respectively hinged to the frame and the connecting rod. The operating rod is "n"-shaped, and its left and right ends are respectively hinged to the rear ends of the two connecting rods. The locking mechanism is located in the middle of the rear surface of the frame. The operating rod is used to engage the top end with the locking mechanism and keep the connecting rod in the highest position so that all flip plates are in a horizontal state.

[0018] Furthermore, the substrate filling device includes a substrate lifting mechanism, a material discharge bin, a soil scraping mechanism, a recovery bin, and a conveyor belt. The material discharge bin and the soil scraping mechanism are sequentially arranged above the belt conveyor line along the conveying direction. The substrate lifting mechanism is located next to the material discharge bin, and its output end is connected to the input end of the material discharge bin. The recovery bin is located at the bottom of the belt conveyor line and directly below the soil scraping mechanism and the material discharge bin. The conveyor belt is located at the bottom output end of the material discharge bin, and its output end is connected to the input end of the substrate lifting mechanism. The substrate lifting mechanism is used to transport substrate soil into the material discharge bin and guide it into each seedling pot through the material discharge bin. The soil scraping mechanism is used to push excess substrate soil in the seedling pot to the outside of the seedling frame. The recovery bin is used to receive the substrate soil discharged by the material discharge bin and the soil scraping mechanism and guide it onto the conveyor belt. The conveyor belt is used to transport the substrate soil to the input end of the substrate lifting mechanism.

[0019] Furthermore, a stirring shaft is horizontally arranged inside the material hopper, and multiple stirring rods are evenly arranged on the outside of the stirring shaft. A first driving assembly is arranged on the outside of the material hopper, and the first driving assembly is connected to one end of the stirring shaft. The first driving assembly is used to drive the stirring shaft to rotate around its own axis, so as to turn the substrate soil in the material hopper toward the output end of the material hopper.

[0020] A baffle mechanism is provided at the bottom of the output end of the discharge hopper, which is used to close or open the output end of the discharge hopper.

[0021] Furthermore, the soil scraping mechanism includes a housing, a second drive assembly, and a soil scraping shaft. The housing is positioned directly above the belt conveyor line, and the lower surface of the housing is open. The soil scraping shaft is horizontally positioned inside the housing, and spiral blades are provided on the outer side of the soil scraping shaft. The second drive assembly is positioned on the housing and connected to the soil scraping shaft. The second drive assembly is used to drive the soil scraping shaft to rotate around its own axis to push the substrate soil overflowing from the top of the seedling pot out from the outside of the seedling frame.

[0022] Furthermore, the spraying device includes a water collection tank, a water supply assembly, a nozzle support, and nozzles. The nozzle support is mounted on a roller conveyor line and has multiple nozzles, with the output ends of the nozzles all facing the roller conveyor line. The water collection tank is located at the bottom of the roller conveyor line and directly below the nozzle support. The water supply assembly is connected to all nozzles via connecting pipes and is used to connect to an external water supply device and supply water to all nozzles.

[0023] Furthermore, the cavitation device includes a frame, a lifting mechanism, and a cavitation plate. The lifting mechanism is positioned directly above the roller conveyor line via the frame. The cavitation plate is horizontally positioned at the bottom lifting end of the lifting mechanism. The lifting mechanism is used to drive the cavitation plate to rise or fall. Multiple cavitation columns are evenly and vertically arranged on the lower surface of the cavitation plate.

[0024] The upper surface of the roller conveyor is provided with guide and limiting mechanisms on both sides directly below the pressing plate. The guide and limiting mechanisms are used to guide the seedling frame to be directly below the pressing plate when the seedling frame moves along the roller conveyor towards the pressing plate.

[0025] Furthermore, the cavitation device also includes an auxiliary plate, which is horizontally positioned directly below the cavitation plate. Multiple guide rods are evenly and vertically arranged on the top of the auxiliary plate, and the auxiliary plate is connected to the cavitation plate via the guide rods. A limiting block is provided at the top of each guide rod to prevent the auxiliary plate from detaching from the guide rod. The auxiliary plate has multiple cavitation holes that cooperate with the cavitation column, and these cavitation holes penetrate the upper and lower surfaces of the auxiliary plate. Multiple flexible baffles are evenly arranged at the top of the inner wall of each cavitation hole, and these baffles are horizontally arranged radially along the cavitation hole. These baffles are used to scrape off the substrate soil outside the cavitation column when the cavitation column moves upward within the cavitation hole.

[0026] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0027] 1. This invention adopts an automated production line to realize the substrate filling, watering and hole pressing production of seedling pots, and uses a conveyor line for transportation, which makes it easy to adjust or add production steps according to actual production needs.

[0028] 2. The seedling frame of the present invention can fix the plastic seedling pots and can hold multiple plastic seedling pots. During the transportation process after the seedling frame has completed the substrate filling, spraying and pressing operations, multiple seedling frames can be stacked vertically and the overall stacking structure is stable. After stacking, they can be transported by forklifts or other handling tools. The bottom of the seedling frame is equipped with a flip-plate mechanism, which makes it easy to discharge all the plastic seedling pots in the seedling frame after the substrate filling, watering and pressing are completed, so that they can be reused.

[0029] 3. The substrate filling device of the present invention can fill substrate soil into the seedling pot. The scraping mechanism can discharge excess substrate soil from the outside of the seedling frame, and the fallen substrate soil can be received by the recycling bin below. Then, it can be transported to the substrate lifting mechanism by the conveyor belt to realize the recycling of substrate soil. In use, the stacking height of substrate soil in the container can be changed by adjusting the height of the scraping mechanism. The baffle mechanism can change the discharge rate of substrate soil in the discharge bin to adjust the filling speed of substrate soil.

[0030] 4. This invention uses a spraying device to water the substrate soil in the container. Multiple spray heads are installed on the spray head bracket, and the installation position of the spray heads can be adjusted to ensure the spraying effect of all seedling pots.

[0031] 5. This invention achieves the hole-pressing function through a hole-pressing device. A lifting mechanism drives the hole-pressing plate to descend, and the bottom of the hole-pressing plate is equipped with multiple hole-pressing columns that conform to the characteristics of the plant rootstock seedlings. The position of each hole-pressing column is aligned with the center of the corresponding seedling pot. By setting an auxiliary plate, after the hole-pressing plate rises, the baffle in the hole-pressing hole will scrape off the substrate soil attached to the outside of the hole-pressing column to clean the adhesive substrate on the outside of the hole-pressing column. In addition, the guide and limiting mechanism on the roller conveyor line can ensure that the seedling frame can move smoothly to the bottom of the hole-pressing plate to achieve hole-pressing positioning and complete the hole-pressing operation.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0051] like Figure 1 and Figure 2 As shown, an automated production line for small diameter-to-depth seedling pots includes a conveyor line 1, and a substrate filling device 2, a spraying device 3, and a hole pressing device 4 arranged sequentially along the conveying direction of the conveyor line 1.

[0052] The conveyor line 1 is used to transport the seedling frame 5 along the transmission direction. The seedling frame 5 is used to support and fix multiple seedling pots, and all seedling pots are neatly arranged inside the seedling frame 5.

[0053] The substrate filling device 2 is used to fill substrate soil into all the seedling pots in the seedling frame 5 and to recycle the excess substrate soil in the seedling pots.

[0054] The spraying device 3 is used to spray water onto all the seedling pots in the seedling frame 5.

[0055] The caving device 4 is used to create cavities on the upper surface of the substrate soil in each seedling pot.

[0056] The seedling frame 5 is equipped with a structure for stacking and forklift operation. After the filling, watering, pressing and transportation operations are completed, all the seedling pots in the seedling frame 5 can be unloaded downwards.

[0057] like Figure 2 As shown, in one embodiment, the conveyor line 1 includes a belt conveyor mechanism 11 and a roller conveyor mechanism 12. The output end of the belt conveyor mechanism 11 is connected to the input end of the roller conveyor mechanism 12. The matrix filling device 2 is disposed on the belt conveyor mechanism 11. The spraying device 3 and the cavitation device 4 are sequentially disposed on the roller conveyor mechanism 12 along the conveying direction.

[0058] (I) Seedling frame

[0059] like Figure 3As shown, the seedling frame 5 includes a frame 51, partitions 52, a flipping mechanism, and a cover plate 54. Multiple horizontally and vertically intersecting partitions 52 are evenly arranged inside the frame 51, and all partitions 52 divide the internal space of the frame 51 into multiple placement areas. The cover plate 54 is detachably installed on the top of the frame 51, and multiple funnel-shaped inlets are opened on the cover plate 54 to facilitate the introduction of received substrate soil into the seedling pots. A flipping mechanism is provided inside the frame 51 below the partitions 52. The flipping mechanism includes a flipping plate 531 located at the bottom of each placement area. The flipping mechanism is used to drive all flipping plates 531 to rotate in a vertical plane to switch between a horizontal state and a vertical state, thereby closing or opening the lower surface of the placement area.

[0060] Both the bottom of the frame 51 and the top of the cover plate 54 are provided with connecting structures. The connecting structures are used to connect two adjacent seedling frames 5 in the vertical direction. Specifically, a stepped structure is provided at the edge of the upper surface of the cover plate 54, and a raised strip that cooperates with the stepped structure is provided at the bottom edge of the frame 51. When the two seedling frames 5 are stacked vertically, the raised strip at the bottom of the upper seedling frame 5 is engaged with the stepped structure on the cover plate 54 of the lower seedling frame 5, so that the two seedling frames 5 are stacked and connected.

[0061] The flip-plate mechanism includes a flip plate 531, a connecting rod 532, an operating rod 533, and a locking mechanism 534. Rectangular openings are provided on both the left and right sides of the frame 51 below the partition 52.

The front and rear ends of all flip plates 531 in the same column are hinged to two rotating shafts, with the two ends of the rotating shaft at the front end connected to the left and right sides of the frame 51, and the two ends of the rotating shaft at the rear end connected to the connecting rods 532 on the left and right sides after passing through the rectangular openings. The operating rod 533 is "n"-shaped, with its left and right ends hinged to the rear ends of the two connecting rods 532. The locking mechanism 534 is located in the middle of the rear surface of the frame 51. The operating rod 533 is used to engage the top end with the locking mechanism 534 and keep the connecting rod 532 in the highest position, so that all flip plates 531 are in a horizontal state.

[0062] In this embodiment, the assembly structure consists of rectangular openings on the left and right sides of the frame 51. For example, during transport, a forklift can insert its forks into the rectangular openings to lift and transport the seedling frame 5, not limited to other methods of transport.

[0063] like Figure 4 As shown, specifically, after the locking mechanism 534 is opened, the connecting rod 532 can be moved downward by moving the operating lever 533 up and down, so that all the flaps 531 can be rotated from the horizontal state to the vertical state, thereby opening the lower surface of all the placement areas.

[0064] like Figure 5 As shown, in this embodiment, the locking mechanism 534 includes a locking base and a movable member. The top end of the operating rod 533 can be hung on the locking base. The movable member is hinged above the locking base and can rotate in a vertical plane. The movable member is a fan-shaped piece. When the operating rod 533 is engaged with the locking base, it will push the movable member to rotate upward. Then the bottom end of the movable member will rotate downward to prevent the operating rod 533 from disengaging from the locking base.

[0078] like Figure 13 and Figure 14 As shown, the cavitation device 4 also includes an auxiliary plate 45, which is horizontally positioned directly below the cavitation plate 43. Multiple guide rods 451 are evenly and vertically arranged on the top of the auxiliary plate 45, and the auxiliary plate 45 is connected to the cavitation plate 43 via the guide rods 451. A limiting block 452 is provided at the top of each guide rod 451 to prevent the auxiliary plate 45 from detaching from the guide rod 451. Multiple cavitation holes 453 are provided on the auxiliary plate 45 to cooperate with the cavitation column 431, and the cavitation holes 453 penetrate the upper and lower surfaces of the auxiliary plate 45. Multiple baffles 454 made of flexible material are evenly arranged at the top of the inner wall of each cavitation hole 453. The baffles 454 are horizontally arranged along the radial direction of the cavitation hole 453 and are used to scrape off the substrate soil outside the cavitation column 431 when the cavitation column 431 moves upward within the cavitation hole 453.

Before the moving substrate filling device 2, the seedling frame 5 is adjusted by the guide and limiting mechanisms so that the seedling frame 5 can be moved smoothly to the bottom of the material drop hopper 22.

[0083] The substrate lifting mechanism 21 delivers the substrate into the discharge bin 22. The first drive component 223 drives the stirring shaft 221 to rotate, and the stirring rod 222 flips the substrate soil towards the output end of the discharge bin. When the seedling frame 5 has not moved below the discharge bin 22, the output end of the discharge bin 22 is closed by the baffle mechanism 224.

[0084] When the seedling frame 5 moves along the belt conveyor 11 to the bottom of the discharge bin 22, the baffle mechanism 224 opens the output end of the discharge bin 22, and the substrate soil is discharged downward from the output end of the discharge bin 22 and guided into the seedling pot through the inlet on the cover plate 54. Then, the seedling frame 5 moves along the belt conveyor 11 to the bottom of the scraping mechanism 23. The second drive component 232 drives the scraping shaft 233 to rotate. The spiral blades on the outside of the scraping shaft 233 push the excess substrate soil on the upper surface of the seedling frame 5 (i.e. the excess substrate soil in the seedling pot) to the outside of the seedling frame 5. The excess substrate soil falls from the outside of the seedling frame 5 into the recycling bin 24 below and is discharged onto the conveyor belt 25 through the recycling bin 24. The conveyor belt 25 then transports the substrate soil to the substrate lifting mechanism 21 for recycling.

[0085] Spraying: Guide and limiting mechanisms are provided on both sides of the upper surface of the roller conveyor mechanism 12, and the guide and limiting mechanisms are located below the nozzle bracket 33. The guide and limiting mechanisms are used to adjust the position of the seedling frame 5 to ensure the spraying effect.

[0086] The seedling frame 5 moves along the belt conveyor 11 to the roller conveyor 12, and then moves along the roller conveyor 12 to the area directly below the nozzle 34. Water is then delivered to all the nozzles 34 through the external water pipe of the water supply assembly 32, and then sprayed into the seedling frame 5 (i.e., into the substrate soil) through the nozzles 34.

[0087] Hole pressing: The seedling frame 5 moves along the roller conveyor mechanism 12 toward the hole pressing device 4. The rod-shaped guide and limiting mechanism 44 guides the seedling frame 5 to be directly below the hole pressing plate 43. The lifting mechanism 42 drives the hole pressing plate 43 to descend. The auxiliary plate 45 is located directly below the hole pressing plate 43. As the hole pressing plate 43 descends, the auxiliary plate 45 first contacts the upper surface of the seedling frame 5. Then, the hole pressing column 431 passes through the corresponding hole pressing hole 453 and is inserted into the corresponding seedling pot, forming a hole in the middle of the substrate soil. Then, the lifting mechanism 42 drives the hole pressing plate 43 to rise. The hole pressing column 431 scrapes away the substrate soil adhering to the outside of the hole pressing column 431 through the hole pressing hole 453 and the baffle 454 inside the hole pressing hole 453. After the hole pressing plate 43 rises to a certain height, the guide rod 451 drives the auxiliary plate 45 to rise until the hole pressing plate 43 rises to the initial position.

[0088] Transfer of seedling frames: After the seedling frames 5 have completed the substrate filling, spraying and pressing operations, they are taken off from the conveyor line 1 and vertically stacked through the connecting structure. After a certain number of seedling frames 5 are stacked, they are transported to the seedling area by forklifts and other handling tools.

[0089] Unloading the seedling pots: After moving a single seedling frame 5 to the designated area, open the locking mechanism 534, use the operating lever 533 to push the connecting rod 532 downward, so that all the flaps 531 rotate in the vertical plane, so that they rotate from the horizontal state to the vertical state, and the seedling pots in the placement area fall from the bottom of the seedling frame 5 under the action of gravity.
