A layered storage device for seed oysters of Fritillaria thunbergii in bags and its working method

Abstract

This invention discloses a layered juvenile fritillaria thunbergii seed spore bagging and storage device and its working method. The invention includes a feeding mechanism, a vibrating sorting mechanism, a seed-blocking and distributing mechanism, a conveying mechanism, and a bagging mechanism. The feeding mechanism conveys the seed spores to the sorting sieve box of the vibrating sorting mechanism. The sorting sieve box grades and screens the seed spores, and the screened seed spores are arranged sequentially in two discharge channels of the sorting sieve box. The two seed-blocking and distributing mechanisms release the seed spores from the two discharge channels one by one. Two chain drive mechanisms in the conveying mechanism drive the corresponding seed-containing cup assemblies to pass sequentially below the outlets of the two discharge channels to collect the falling seed spores, and then sequentially pass above the two bagging mechanisms to place the seed spores into the cylindrical mesh bags of the two bagging mechanisms, completing the bagging of the seed spores. This invention enables the grading and single-seed bagging of seed spores before sowing, reducing the risk of rolling collisions and mixing of seed spores during turnover.

Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery and equipment, specifically relating to a layered Zhejiang fritillary bulb seed storage and bagging device and its working method. Background Technology

[0002] Fritillaria thunbergii is a commonly used and valuable traditional Chinese medicine, primarily propagated through seed stock. Before sowing, the seed stock typically undergoes screening and grading, weighing and packaging, short-term storage, loading, unloading, and transportation. During these processes, the seed stock is often repeatedly transferred and stacked. Without effective physical restraint and isolation measures, it is prone to rolling displacement, collisions, and mixed accumulation, leading to problems such as unstable posture, abrasions, contamination, moisture absorption, and difficulties in batch management, thus affecting the reliability of sowing preparation and operational efficiency.

[0003] Currently, the turnover of smelt shellfish mostly adopts bulk (basket, bag, turnover box, etc.) or simple repackaging methods. Although convenient to operate, these methods still have the following shortcomings in engineering applications: First, the lack of individual shellfish containment and isolation makes collisions and compression during turnover difficult to avoid; second, it is difficult to achieve unitized management and rapid retrieval by quantity and batch, resulting in high manual handling costs; third, the connection with subsequent feeding or unpacking processes is poor, making it difficult to form a continuous operation process. Therefore, the industry still lacks a dedicated device that can bag and package smelt shellfish in individual units for centralized storage and transportation, making it necessary to provide a bagged storage device. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and to propose a layered Zhejiang fritillary bulb seed storage and bagging device and its working method.

The front and rear stops are driven by the drive unit to rotate in opposite directions. The conveying mechanism includes a frame, a chain drive mechanism, and seed-containing cup assemblies.

Two guide frames are fixed on the cup body in a symmetrical arrangement. Each cylindrical pin and the arc-shaped guide rail opened on the adjacent guide frame form a slot pin pair. The lower ends of the two symmetrically arranged rotating rods are respectively hinged to the lower ends of the two guide frames. The middle part is connected to the cup body through a tension spring, and each part is provided with an integrally formed limiting rod in the middle. The upper end of each part is provided with an integrally formed ball head. The end of the limiting rod away from the corresponding rotating rod is provided with an integrally formed arc plate.

[0009] Below each chain drive mechanism is a bagging mechanism. The bagging mechanism includes a fixed frame, a lifting plate, a reset assembly, a bagging tube, a brush roller assembly, and a second drive component. The fixed frame is fixed to the second frame, and the horizontally positioned lifting plate is driven to rise and fall by the lifting mechanism. The lifting plate has holes, and a reset assembly is located on its upper surface. The reset assembly includes an arc plate and guide plates. Two symmetrically arranged arc plates are fixed to the lifting plate and located on either side of the holes. The inner surfaces of both arc plates have arc-shaped grooves. Two guide plates are fixed to the lifting plate, located at the outer edge of the holes away from the feeding mechanism, and are symmetrically arranged about the two arc plates.

The spacing at one end is greater than the spacing at the end furthest from the hole, and the tops of the two guide plates are provided with inclined surfaces; the lower surface of the lifting plate is provided with two annular plates that are coaxial with the hole and spaced apart. The inner annular plate is a cone-shaped tube with a large opening at the top and a small opening at the bottom, and an infrared sensor is provided on the inner side of the inner annular plate; a vertically arranged bag tube is fixed on the fixed frame directly below the hole. The upper and lower ends of the bag tube are provided with brush roller groups. The brush roller groups consist of two brush rollers arranged symmetrically.

[0010] Preferably, the feeding mechanism includes a frame three, a hopper, and a belt conveyor mechanism. The belt conveyor mechanism is mounted on the frame three, and the input end of the belt conveyor mechanism is lower than the output end. Multiple partition strips are fixed on the conveyor belt of the belt conveyor mechanism at equal intervals. The hopper is fixed on the frame three and located at the input end of the belt conveyor mechanism. A straight guide plate is located at the output end of the belt conveyor mechanism.

[0011] Preferably, spring seats are fixed at both ends of the outer side of the side plate, and each spring seat is connected to the frame through a support spring.

[0012] Preferably, the straight guide plate, the primary screening plate and the secondary screening plate are all higher at one end than the other end near the feeding mechanism, and the U-shaped box is lower at one end than the other end near the feeding mechanism.

[0013] Preferably, the driving component one includes a driving gear one, a driven gear one, and a support plate. The support plate is horizontally fixed to the outer side of the adjacent side plate. The driving gear one and the driven gear one mesh and are both hinged to the support plate. The driving gear one is driven to rotate by a drive motor one. The front stop and the rear stop are respectively fixed to the driving gear one and the driven gear one.

[0014] Preferably, the second driving component includes a rotating shaft, a second driving gear, and a second driven gear. Two rotating shafts are arranged horizontally and parallelly on both sides of the corresponding bag tube and each forms a rotating pair with the corresponding fixed frame. The second driving gear is located between the two rotating shafts, forms a rotating pair with the corresponding fixed frame, and is driven to rotate by the second driving motor. The two second driven gears are fixed on the two rotating shafts and mesh with the second driving gear. The two brush rollers are fixed on the two rotating shafts.

[0015] More preferably, the lower end of the bag tube is fixed and connected to the curved guide tube, and the free end of the curved guide tube is upturned.

[0016] The working method of the layered Zhejiang fritillary bulb seed storage and bagging device of the present invention is as follows:

[0017] Two tubular mesh bags are respectively placed on the outside of two bag tubes, and the open end of each tubular mesh bag is inserted into the corresponding curved guide tube through the corresponding bag tube, and the sealed end is located at the upper end of the corresponding bag tube; in the initial state, the rear stop bar of each type distribution mechanism is closed and the front stop bar is open; the upper end of each bag tube is embedded in the gap between the corresponding two annular plates, and the annular plate on the inner side of each lifting plate opens the corresponding tubular mesh bag; the two semi-circular bottom plates in each type cup assembly are combined, and each brush roller makes the corresponding tubular mesh bag adhere to the outer wall of the corresponding bag tube;

[0018] Then, the feeding mechanism operates for the preset time, and at the same time, the controller controls the vibration motor to drive the entire sorting screen box to vibrate. The feeding mechanism conveys the seed shells, so that the seed shells fall onto the flat guide plate. Guided by the flat guide plate, the seed shells fall onto the first screening plate. Among these seed shells, those with a diameter smaller than the first screen hole fall onto the second screening plate through each screen hole. Those with a diameter larger than the first screen hole roll to the lower end of the first screening plate and fall into the collection box one through the guidance of the arc guide plate. Among the seed shells on the second screening plate, those with a diameter smaller than the second screen hole fall into the U-shaped box through each screen hole. Those with a diameter larger than the second screen hole are arranged in the two discharge channels in sequence. One seed shell at the outlet of each discharge channel touches the back stop bar, while the seed shells falling into the U-shaped box roll into the collection box two through the rectangular opening.

[0019] Then, each chain drive mechanism operates, driving each seed-containing cup assembly to move. Whenever an infrared sensor detects that the corresponding chain drive mechanism has moved a seed-containing cup assembly to below the corresponding discharge channel outlet, the drive unit drives the front and rear stop levers to rotate in opposite directions. This causes the rear stop lever to open, allowing a seed shell located between the front and rear stop levers to fall into the corresponding seed-containing cup assembly. The front stop lever closes, and any seed shells that touch the rear stop lever fall into the corresponding seed-containing cup assembly. The front stop lever prevents any remaining seed shells from exiting the discharge channel outlet. Whenever an infrared sensor detects that the corresponding chain drive mechanism has moved a seed-containing cup assembly away from below the corresponding discharge channel outlet, the drive unit drives... The front and rear stops rotate in opposite directions, opening the front stop and closing the rear stop, allowing a new seed oyster to touch the rear stop. As each chain drive mechanism moves, when each seed-holding cup assembly carrying the seed oyster moves sequentially above the corresponding bagging mechanism, two ball heads in each seed-holding cup assembly enter the arc-shaped grooves on two arc plates and move along these grooves. The ball heads drive the limiting rods to rotate via rotating rods, causing the arc plates on the two limiting rods to disengage from the corresponding cylindrical pins. The two semi-circular base plates rotate downwards under their own weight and the weight of the seed oyster, allowing the seed oyster to fall through the corresponding holes into the corresponding cylindrical mesh bag. Furthermore, with the movement of the corresponding chain drive mechanism, the two... The ball head disengages from the two arc-shaped grooves, and each rotating rod resets under the action of the corresponding tension spring. The two opened semi-circular bottom plates enter between the two guide plates and rotate towards each other until they merge under the convergence of the two guide plates and the pushing action of the two inclined surfaces. The lower end outlet of the cup closes. When the two semi-circular bottom plates rotate towards each other, they drive the two cylindrical pins to rotate downward along the corresponding arc-shaped guide rails through the two connecting rods, and push the arc-shaped plates to drive the corresponding rotating rods to rotate until each cylindrical pin contacts the arc-shaped convex surface of the corresponding arc plate. At the same time, each rotating rod resets again under the action of the corresponding tension spring, locking the corresponding cylindrical pins. Each driving component drives the two brush rollers of the corresponding brush roller group to rotate at a preset speed. With a quick rotation, the portions of each cylindrical mesh bag located outside the corresponding bagging tube move upwards, while the portions located inside the corresponding bagging tube move downwards under the gravity of the seed clams falling into the bagging tube. The portions of the seed clams, except for the top and bottom ends, are contracted and wrapped by the annular plates on the inner side of the corresponding lifting plates. As each seed distribution mechanism outputs individual seed clams, each chain drive mechanism drives each seed cup assembly to sequentially receive and release seed clams, and each drive component drives each brush roller group to convey the cylindrical mesh bags. The cylindrical mesh bags containing seed clams gradually enter the inner side of the curved guide tube from the inner side of the bagging tube, and finally exit from the outlet of the curved guide tube, completing the continuous bagging of seed clams.

[0020] Preferably, the process of placing the tubular mesh bag outside the bagging tube and the curved guide tube is as follows: The lifting mechanism drives the lifting plate to rise to a preset height, so that the upper end of the bagging tube is disengaged from the gap between the corresponding two annular plates; the open end of the tubular mesh bag is first inserted into the curved guide tube and out of the bagging tube by hand, and then the inside of the open end of the tubular mesh bag is turned out so that the open end of the tubular mesh bag is placed outside the bagging tube and pressed between the two brush rollers of the corresponding upper brush roller group. The two driving components drive the two brush roller groups so that the open end of the tubular mesh bag moves continuously to the lower end of the bagging tube and is pressed between the two brush rollers of the corresponding lower brush roller group, and then is placed outside the curved guide tube until the sealed end of the tubular mesh bag reaches the upper end of the corresponding bagging tube. The controller controls the upper driving component to stop moving; then the lifting mechanism drives the lifting plate to fall to a preset height so that the upper end of the bagging tube is embedded in the gap between the corresponding two annular plates.

[0021] Preferably, when each infrared sensor 2 detects that a preset number of seed shells have passed through the corresponding holes, each driving component 2 drives the two brush rollers of the corresponding brush roller group to rotate at a preset speed 2, so that the part of the cylindrical net bag located inside the bag tube has an additional preset length of empty bag section without seed shells after the preset number of seed shells are filled.

[0022] The present invention has the following beneficial effects:

[0023] This invention enables the grading and single-bagged (separating adjacent seed shells) of seed shells before sowing, reducing the risk of rolling collisions and mixing during the handling process. This facilitates subsequent feeding or unbagging operations, improving the engineering adaptability and operational efficiency of the sowing preparation phase. Specifically, the invention uses a feeding mechanism to transport the seed shells to the primary screening plate of the sorting sieve box in a vibrating sorting mechanism. A vibrating motor in the vibrating sorting mechanism drives the secondary screening plate, causing the entire sorting sieve box to vibrate. This causes seed shells with a diameter smaller than the first sieve hole on the primary screening plate to fall through the first sieve hole onto the secondary screening plate, while seed shells with a diameter smaller than the second sieve hole on the secondary screening plate fall through the second sieve hole into the U-shaped box, thus achieving grading and sorting of the seed shells. The seed shells remaining on the secondary screening plate are arranged sequentially in two discharge channels. Then, two chain drive mechanisms in the conveying mechanism drive... The corresponding seed-holding cup assemblies first pass under the two discharge channel outlets in sequence, and then pass over the two bagging mechanisms in sequence. Whenever a seed-holding cup assembly moves to the area below the corresponding discharge channel outlet, the driving component in the seed-blocking and distributing mechanism located at the discharge channel outlet drives the front and rear stop levers to rotate in opposite directions, causing the rear stop lever to open and a seed shell to fall into the cup body of the corresponding seed-holding cup assembly. Simultaneously, the front stop lever closes, preventing any remaining seed shells from exiting the discharge channel outlet. Whenever a seed-holding cup assembly carrying seed shells moves to the area above the corresponding bagging mechanism, the two semi-circular bottom plates below the cup body open. The seed clams inside the cup fall into the cylindrical mesh bags fitted onto the bagging tube in the bagging mechanism. Simultaneously, each drive component drives each brush roller assembly, pushing the portion of the cylindrical mesh bag located outside the corresponding bagging tube upwards. This causes the portion of the cylindrical mesh bag located inside the corresponding bagging tube to move downwards under the gravity of the seed clams falling into the bagging tube. This portion of the cylindrical mesh bag automatically contracts to wrap around the current seed clam, except for its top and bottom ends, thus separating adjacent seed clams. As each seed distribution mechanism outputs individual seed clams, each chain drive mechanism drives each seed-containing cup assembly to sequentially receive and release the seed clams. Each drive unit drives each brush roller group to convey a cylindrical mesh bag. The cylindrical mesh bag containing seed oysters gradually enters the inner side of the curved guide tube from the inside of the bagging tube, and finally exits from the outlet of the curved guide tube, thus realizing continuous bagging of seed oysters. After the cylindrical mesh bag contains a preset number of seed oysters, an additional preset length of empty bag section is left. After the cylindrical mesh bag containing seed oysters exits from the outlet of the curved guide tube, the empty bag section is manually cut, and the open ends of the cylindrical mesh bag on both sides of the cut are sealed, finally dividing the entire cylindrical mesh bag into multiple sections, with both ends of each section sealed. This invention reduces the risk of rolling collisions and mixing of seed oysters during turnover by protecting them and restricting their position through the cylindrical mesh bag, facilitating subsequent feeding or bag removal operations, and improving the engineering adaptability and operational efficiency of the sowing preparation stage.

In the initial state, the rear stop bar 3-2 of each seed distribution mechanism 3 is closed relative to the outlet of the discharge channel (i.e., blocking the outlet of the discharge channel), and the front stop bar 3-1 is open relative to the outlet of the discharge channel. The upper end of each bag tube 5-4 is embedded in the gap between the corresponding two annular plates. The two semi-circular bottom plates 4-3-3 in each seed cup assembly 4-3 are combined to close the outlet at the lower end of the cup body 4-3-1. The two cylindrical pins 4-3-3-2 are located at the lower end of the corresponding arc-shaped guide rail, and the arc concave surface of the two arc plates contacts the two cylindrical pins 4-3-3-2. The two arc plates hold the two cylindrical pins 4-3-3-2.

[0046] Each lifting mechanism drives each lifting plate 5-2 to rise to a preset height, causing the upper end of each bag tube 5-4 to disengage from the gap between the corresponding two annular plates. Two tubular mesh bags 6 are then placed on the outside of the two bag tubes 5-4 respectively, with the open end of each tubular mesh bag 6 passing through the corresponding bag tube 5-4 and entering the corresponding curved guide tube 5-7. The sealed end is located at the upper end of the corresponding bag tube 5-4. Each brush roller causes the corresponding tubular mesh bag 6 to adhere to the outer wall of the corresponding bag tube 5-4. Then, each lifting mechanism drives each lifting plate 5-2 to descend to a preset height, causing the upper end of each bag tube 5-4 to embed into the gap between the corresponding two annular plates. The annular plate on the inner side of each lifting plate 5-2 opens the corresponding tubular mesh bag 6, while the annular plate on the outer side guides the corresponding tubular mesh bag 6. The process involves placing a tubular mesh bag 6 outside the bagging tube 5-4 and the curved guide tube 5-7. Specifically, the open end of the tubular mesh bag 6 is manually inserted through the curved guide tube 5-7 and exits through the bagging tube 5-4. Then, the inside of the open end of the tubular mesh bag 6 is turned outwards, so that the open end of the tubular mesh bag 6 is placed outside the bagging tube 5-4 and pressed between the two brush rollers of the corresponding upper brush roller group 5-5. Two driving components 5-6 drive the two brush roller groups 5-5 in opposite directions, causing the open end of the tubular mesh bag 6 to continuously move towards the lower end of the bagging tube 5-4 and be pressed between the two brush rollers of the corresponding lower brush roller group 5-5. It is then placed outside the curved guide tube 5-7 until the sealed end of the tubular mesh bag 6 reaches the upper end of the corresponding bagging tube 5-4. Finally, the controller stops the movement of the upper driving component 5-6.

[0047] Next, the conveyor mechanism 1-3 operates for a preset time, and simultaneously, the controller controls the vibration motor 2-4 to drive the secondary screening plate 2-2-4, causing the entire sorting sieve box 2-2 to vibrate. The conveyor mechanism 1-3 conveys the seed shells 7 upwards through the separators 1-4, causing the seed shells 7 to fall onto the straight guide plate 2-2-2. Guided by the straight guide plate 2-2-2, the seed shells 7 fall onto the primary screening plate 2-2-3. With the vibration of the entire sorting sieve box 2-2, the seed shells 7 with a diameter smaller than the first sieve hole 2-2-8 that fall on the primary screening plate 2-2-3 pass through the first sieve hole 2-2-8 and fall onto the secondary screening plate 2-2-4, while those with a diameter larger than the first sieve hole 2-2-8 fall onto the secondary screening plate 2-2-4. Seed shellfish 7 with sieve hole 2-2-8 roll to the lower end of the primary screening plate 2-2-3 and, guided by the arc-shaped guide plate 2-2-7, fall into the collection box 1. Seed shellfish 7 on the secondary screening plate 2-2-4 have a diameter smaller than sieve hole 2-2-9 and fall into the U-shaped box 2-2-5 through each sieve hole 2-2-9. Seed shellfish 7 with a diameter larger than sieve hole 2-2-9 are arranged in the two discharge channels. One seed shellfish 7 at the outlet of each discharge channel touches the back stop bar 3-2. Seed shellfish 7 in the U-shaped box 2-2-5 roll into the collection box 2 through the rectangular opening, thus achieving the grading of seed shellfish 7.

[0048] Then, each chain drive mechanism 4-2 operates, driving each seed cup assembly 4-3 to move; whenever each infrared sensor detects that the corresponding chain drive mechanism 4-2 has driven a seed cup assembly 4-3 to move to below the outlet of the corresponding discharge channel, the controller controls the drive motor 3-6 in the corresponding seed distribution mechanism 3 to drive the drive gear 3-3 to rotate forward. The drive gear 3-3 and the driven gear 3-4 mesh, thereby driving the front stop 3-1 and the rear stop 3-2 to rotate in opposite directions, so that the rear stop 3-2 opens and the front stop 3-1 closes, and the seed cup 7 touches the rear stop 3-2. The seed pods fall into the cup body 4-3-1 of the corresponding seed cup assembly 4-3, and the front stop 3-1 prevents the remaining seed pods 7 from leaving the outlet of the discharge channel. Whenever each infrared sensor detects that the corresponding chain drive mechanism 4-2 drives a seed cup assembly 4-3 away from the outlet of the corresponding discharge channel, the controller controls the drive motor 3-6 in the corresponding seed distribution mechanism 3 to drive the drive gear 3-3 to reverse, causing the front stop 3-1 and the rear stop 3-2 to rotate in opposite directions, so that the front stop 3-1 opens and the rear stop 3-2 closes, so that a new seed pod 7 touches the rear stop 3-2.As each chain drive mechanism 4-2 moves, when each seed-containing cup assembly 4-3 carrying the seed shell 7 moves sequentially above the corresponding bagging mechanism 5, the two ball heads 4-3-5-1 in each seed-containing cup assembly 4-3 enter the arc-shaped grooves on the two arc plates 5-3-1 and move along the two arc-shaped grooves. The ball heads 4-3-5-1 drive the limiting rods 4-3-5 to rotate through the rotating rods 4-3-5, causing the arc-shaped plates on the two limiting rods 4-3-5-2 to disengage from the corresponding cylindrical pins 4-3-3-2, and the two semi-circular bottom plates... Under its own weight and the weight of the corresponding shellfish 7, 4-3-3 rotates downwards. The lower outlet of the cup body 4-3-1 opens, and the shellfish 7 falls into the corresponding hole and then into the corresponding cylindrical mesh bag 6. As the corresponding chain drive mechanism 4-2 moves, the two ball heads 4-3-5-1 disengage from the two arc-shaped grooves. Each rotating rod 4-3-5 returns to its original position under the action of the corresponding tension spring 4-3-6. The two open semi-circular bottom plates 4-3-3 enter between the two guide plates 5-3-2 and remain between the two guide plates 5-3-2. Under the converging action of 3-2 and the pushing action of the two inclined planes, they rotate towards each other until they merge. The lower outlet of the cup body 4-3-1 closes. When the two semi-circular base plates 4-3-3 rotate towards each other, they drive the two cylindrical pins 4-3-3-2 to rotate downward along the corresponding arc-shaped guide rails through the two connecting rods 4-3-3-1. This pushes the arc plate to drive the corresponding rotating rods 4-3-5 to rotate until each cylindrical pin 4-3-3-2 contacts the arc-shaped convex surface of the corresponding arc plate. At the same time, each rotating rod 4-3-5 is again pushed by the corresponding tension spring 4-3-6 to return to its original position. Position, lock the corresponding cylindrical pin 4-3-3-2; each driving component 5-6 drives the two brush rollers of the corresponding brush roller group 5-5 to rotate at a preset speed, so that the part of each cylindrical net bag 6 located outside the corresponding bag tube 5-4 moves upward, and the part located inside the corresponding bag tube 5-4 moves downward under the gravity of the seed shell 7 falling into the bag tube 5-4, and the part opened by the annular plate on the inner side of the corresponding lifting plate 5-2 shrinks and wraps the part of the current seed shell 7 except for the upper and lower ends, so that adjacent seed shells are separated, such as. Figure 12 As shown; with each seed distribution mechanism 3 outputting a single seed shell 7, each chain drive mechanism 4-2 drives each seed cup assembly 4-3 to sequentially pick up and put the seed shell 7, and each drive component 5-6 drives each brush roller assembly 5-5 to convey the cylindrical mesh bag 6. The cylindrical mesh bag 6 containing the seed shell 7 gradually enters the inner side of the curved guide tube 5-7 from the inner side of the bagging tube 5-4, and finally exits from the outlet of the curved guide tube 5-7, realizing the continuous bagging operation of the seed shell 7.

[0049] When each infrared sensor detects a preset number of seed shells 7 passing through the corresponding holes, each drive component 5-6 drives the two brush rollers of the corresponding brush roller group 5-5 to rotate at a preset speed. This causes the portion of the tubular mesh bag 6 located inside the bag tube 5-4 to have an additional preset length of empty bag section without seed shells 7 after the preset number of seed shells 7 are loaded. After the tubular mesh bag 6 containing seed shells 7 is output from the curved guide tube 5-7, it is used for subsequent manual cutting and sealing of the opening ends of the tubular mesh bag 6 on both sides of the cut. Finally, the entire tubular net bag 6 is divided into multiple segments, and both ends of each segment are sealed. In addition, when the portion of each tubular net bag 6 located inside the corresponding bagging tube 5-4 moves down into the corresponding curved guide tube 5-7, each curved guide tube 5-7 supports and guides the corresponding tubular net bag 6 containing the seed shells 7, reducing the downward pull of the seed shells 7 on each tubular net bag 6, and inhibiting the downward fall of the portion of each tubular net bag 6 located inside the corresponding bagging tube 5-4, thus ensuring the stable operation of continuous bagging of the seed shells 7.

8. The working method of the layered Zhejiang fritillary bulb seed storage and bagging device according to claim 7, characterized in that: Specifically as follows: Two tubular mesh bags are respectively placed on the outside of two bag tubes, and the open end of each tubular mesh bag is inserted into the corresponding curved guide tube through the corresponding bag tube, and the sealed end is located at the upper end of the corresponding bag tube; in the initial state, the rear stop bar of each type distribution mechanism is closed and the front stop bar is open; the upper end of each bag tube is embedded in the gap between the corresponding two annular plates, and the annular plate on the inner side of each lifting plate opens the corresponding tubular mesh bag; the two semi-circular bottom plates in each type cup assembly are combined, and each brush roller makes the corresponding tubular mesh bag adhere to the outer wall of the corresponding bag tube; Then, the feeding mechanism operates for the preset time, and at the same time, the controller controls the vibration motor to drive the entire sorting screen box to vibrate. The feeding mechanism conveys the seed shells, so that the seed shells fall onto the flat guide plate. Guided by the flat guide plate, the seed shells fall onto the first screening plate. Among these seed shells, those with a diameter smaller than the first screen hole fall onto the second screening plate through each screen hole. Those with a diameter larger than the first screen hole roll to the lower end of the first screening plate and fall into the collection box one through the guidance of the arc guide plate. Among the seed shells on the second screening plate, those with a diameter smaller than the second screen hole fall into the U-shaped box through each screen hole. Those with a diameter larger than the second screen hole are arranged in the two discharge channels in sequence. One seed shell at the outlet of each discharge channel touches the back stop bar, while the seed shells falling into the U-shaped box roll into the collection box two through the rectangular opening. Then, each chain drive mechanism operates, driving each seed-containing cup assembly to move. Whenever an infrared sensor detects that the corresponding chain drive mechanism has moved a seed-containing cup assembly to below the corresponding discharge channel outlet, the drive unit drives the front and rear stop levers to rotate in opposite directions. This causes the rear stop lever to open, allowing a seed shell located between the front and rear stop levers to fall into the corresponding seed-containing cup assembly. The front stop lever closes, and any seed shells that touch the rear stop lever fall into the corresponding seed-containing cup assembly. The front stop lever prevents any remaining seed shells from exiting the discharge channel outlet. Whenever an infrared sensor detects that the corresponding chain drive mechanism has moved a seed-containing cup assembly away from below the corresponding discharge channel outlet, the drive unit drives... The front and rear stops rotate in opposite directions, opening the front stop and closing the rear stop, allowing a new seed oyster to touch the rear stop. As each chain drive mechanism moves, when each seed-holding cup assembly carrying the seed oyster moves sequentially above the corresponding bagging mechanism, two ball heads in each seed-holding cup assembly enter the arc-shaped grooves on two arc plates and move along these grooves. The ball heads drive the limiting rods to rotate via rotating rods, causing the arc plates on the two limiting rods to disengage from the corresponding cylindrical pins. The two semi-circular base plates rotate downwards under their own weight and the weight of the seed oyster, allowing the seed oyster to fall through the corresponding holes into the corresponding cylindrical mesh bag. Furthermore, with the movement of the corresponding chain drive mechanism, the two... The ball head disengages from the two arc-shaped grooves, and each rotating rod resets under the action of the corresponding tension spring. The two opened semi-circular bottom plates enter between the two guide plates and rotate towards each other until they merge under the convergence of the two guide plates and the pushing action of the two inclined surfaces. The lower end outlet of the cup closes. When the two semi-circular bottom plates rotate towards each other, they drive the two cylindrical pins to rotate downward along the corresponding arc-shaped guide rails through the two connecting rods, and push the arc-shaped plates to drive the corresponding rotating rods to rotate until each cylindrical pin contacts the arc-shaped convex surface of the corresponding arc plate. At the same time, each rotating rod resets again under the action of the corresponding tension spring, locking the corresponding cylindrical pins. Each driving component drives the two brush rollers of the corresponding brush roller group to rotate at a preset speed. With a quick rotation, the portions of each cylindrical mesh bag located outside the corresponding bagging tube move upwards, while the portions located inside the corresponding bagging tube move downwards under the gravity of the seed clams falling into the bagging tube. The portions of the seed clams, except for the top and bottom ends, are contracted and wrapped by the annular plates on the inner side of the corresponding lifting plates. As each seed distribution mechanism outputs individual seed clams, each chain drive mechanism drives each seed cup assembly to sequentially receive and release seed clams, and each drive component drives each brush roller group to convey the cylindrical mesh bags. The cylindrical mesh bags containing seed clams gradually enter the inner side of the curved guide tube from the inner side of the bagging tube, and finally exit from the outlet of the curved guide tube, completing the continuous bagging of seed clams.

9. The working method of the layered Zhejiang fritillary bulb seed germination bagging and storage device according to claim 8, characterized in that: The process of placing the tubular mesh bag outside the bagging tube and the curved guide tube is as follows: The lifting mechanism drives the lifting plate to rise to a preset height, so that the upper end of the bagging tube is disengaged from the gap between the two corresponding annular plates; the manual first inserts the open end of the tubular mesh bag into the curved guide tube and out of the bagging tube, then flips the inside of the open end of the tubular mesh bag out, so that the open end of the tubular mesh bag is placed on the outside of the bagging tube and pressed between the two brush rollers of the corresponding upper brush roller group. The two driving components drive the two brush roller groups, so that the open end of the tubular mesh bag moves continuously to the lower end of the outside of the bagging tube and is pressed between the two brush rollers of the corresponding lower brush roller group, and then is placed on the outside of the curved guide tube until the sealed end of the tubular mesh bag reaches the upper end of the corresponding bagging tube. The controller controls the upper driving component to stop moving; then the lifting mechanism drives the lifting plate to fall to a preset height, so that the upper end of the bagging tube is embedded in the gap between the two corresponding annular plates.

10. The working method of the layered Zhejiang fritillary bulb seed storage and bagging device according to claim 8, characterized in that: When each infrared sensor detects a preset number of seed shells passing through the corresponding holes, each drive unit drives the two brush rollers of the corresponding brush roller group to rotate at a preset speed, so that the part of the cylindrical net bag located inside the bag tube has an additional preset length of empty bag section without seed shells after the preset number of seed shells are filled.
