Description

Technical Field

[0001] This invention relates to the field of seedling technology, specifically a seedling raising device for planting Solomon's seal. Background Technology

[0002] Polygonatum odoratum, also known as Solomon's seal, is a commonly used traditional Chinese medicine with functions of nourishing yin and moistening dryness, promoting body fluid production and quenching thirst. When grown under natural conditions, Polygonatum odoratum is prone to poor growth, which affects the quality and yield of the medicinal material. Therefore, seedling cultivation is necessary. Developing high-quality seedlings before planting helps to ensure stable and reliable cultivation of the medicinal material. This is where seedling cultivation equipment comes in, for example:

[0003] A Chinese patent with authorization announcement number CN221011025U discloses a seedling raising device for planting Solomon's seal, including a base, a collective feeding mechanism fixedly installed on the top surface of the base, a tall outer pot assembly fixedly installed on the top surface of the collective feeding mechanism, a side pushing component slidably installed on the side wall of the tall outer pot assembly, and a rubber inner pot provided inside the tall outer pot assembly.

[0004] While the technical solutions in the aforementioned patent documents can assist in removing seedlings from their pots, they still have the following drawbacks in actual operation: Seeds are cultivated into seedlings in cultivation pots, and their roots become intertwined in the cultivation pots, resulting in a strong adhesion effect with the inner wall of the cultivation pots. The aforementioned technical solutions use a squeezing method to squeeze the seedlings and cultivation substrate out of the cultivation pots as a whole. This method of removing seedlings from their pots not only easily damages the root system of the seedlings, affecting their survival rate, but also easily causes the cultivation substrate to break, increasing the risk of seedling transplantation. Furthermore, the broken cultivation substrate will cause pollution to the cultivation equipment, increasing the cleaning burden on the staff. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, this invention provides a seedling cultivation device for Solomon's Seal (Polygonatum odoratum). By adding an electric slide rail and a ring-cutting mechanism to the planting bed, when it is necessary to remove seedlings from the cultivation pots, the ring-cutting mechanism first ring-cuts the edge of the cultivation substrate in each cultivation pot, thereby separating the seedling roots from the inner wall of the cultivation pot. This facilitates the removal of seedlings from their pots. Furthermore, the ring-cutting mechanism also has a cleaning and disinfection function for the blades, thereby reducing viral infection between seedlings caused by the ring-cutting process and ensuring the survival rate of transplanted seedlings, thus solving the problems mentioned in the background art.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. By adding an electric slide rail and a ring-cutting mechanism to the planting bed, when it is necessary to remove the seedlings from the pots, the ring-cutting mechanism first rings the edge of the cultivation substrate in each pot, so as to separate the seedling roots from the inner wall of the pot, thus facilitating the removal of the seedlings from the pots.

[0029] 2. The ring-cutting mechanism also has the function of cleaning and disinfecting the blades. Therefore, after each ring-cutting treatment of the seedling roots in the cultivation pot, the blades will be cleaned and disinfected to reduce the viral infection between seedlings caused by the ring-cutting treatment and ensure the survival rate of seedling transplantation.

[0030] 3. By installing a sealing component at the bottom of the nursery bed in the planting bed, when the seedlings are watered or fertilized, the squeezing parts on the spraying mechanism move downward as it moves, thus opening the seal on the bottom of the seedling bed and allowing the liquid accumulated inside to be discharged, thereby ensuring the humidity environment in the cultivation pot and achieving stable cultivation of the seedlings.

[0031] 4. The nursery structure is equipped with a pushing component. When the girdling mechanism moves, the auxiliary components arranged on it can squeeze the pushing component, thereby pushing the bottom of the corresponding cultivation pots that have been girdled in the nursery structure. This pushes the girdled cultivation substrate and seedlings, further facilitating the transplanting and removal of seedlings from their pots. Attached Figure Description

Detailed Implementation

[0045] Please see Figures 1-2In this embodiment of the invention, a seedling raising device for planting Solomon's Seal includes a planting bed, which includes a frame 1 and a nursery mechanism 5. The nursery mechanism 5 is located on the top of the frame 1 and is used for cultivating seedlings. By cultivating seedlings through the planting bed, the rate of high-quality seedlings is improved.

[0046] Below the nursery mechanism 5, there is also a collection box 2 and a moving mechanism 3 located on the frame 1. The collection box 2 is used to hold the liquid discharged from the nursery mechanism 5. The collection box 2 is filled with water-absorbing material to collect the dripping liquid. The water-absorbing material is diverse, and in this embodiment, sponge material is used.

[0047] The mobile mechanism 3 is equipped with a spraying mechanism 4 for watering and fertilizing the seedlings. The spraying mechanism 4 is in contact with the nursery mechanism 5. The spraying mechanism 4 is connected to an external water source and liquid fertilizer source, thereby ensuring the growth needs of the seedlings in the planting bed.

[0048] The rear side of the nursery mechanism 5 is provided with an electric slide rail 6 located on the frame 1. A ring-cutting mechanism 7 is installed on the electric slide rail 6.

The electric push rod 72 and the liquid storage box 73 are both mounted on the top outer wall of the support arm 71, and the liquid storage box 73 is located on the left side of the electric push rod 72. The output end of the electric push rod 72 penetrates the top shell wall of the support arm 71. The splicing frame 74 is mounted on the output end of the electric push rod 72, so that the operation of the electric push rod 72 can drive the splicing frame 74 to perform lifting and lowering movements.

[0050] The straight plate 75 is fixedly connected to the bottom of the splicing frame 74. The ring-cutting components 76 include multiple components, which are arranged horizontally and linearly on the straight plate 75. The multiple ring-cutting components 76 drive each other. When the splicing frame 74 is raised and lowered, it synchronously drives the straight plate 75 to move, thereby driving the multiple ring-cutting components 76 to move synchronously.

[0051] The positioning component 77 is movably connected to the straight plate 75, the driving component 78 is located on the rear side of the straight plate 75 and provides power for the operation of multiple circumferential cutting components 76, and the auxiliary component 79 is located on the inner side wall of the support arm 71.

[0052] When the driving component 78 runs, it enables the activity of multiple girdling components 76, thereby achieving girdling treatment of the root system of the corresponding seedling.

[0053] Please see Figures 1-4 In this embodiment of the invention, the frame 1 includes two square bars 11 arranged symmetrically at the front and back. The tops of the two square bars 11 are both set on the nursery mechanism 5, and the square bars 11 are used to support the nursery mechanism 5.

[0054] Two horizontal plates 12 are symmetrically arranged at the bottom of the two square bars 11. Each horizontal plate 12 is equipped with support legs 13 for support at the front and rear ends. There are various ways to connect the horizontal plates 12 and the square bars 11. In this embodiment, bolt fixing is used for assembly.

[0055] A longitudinal tie rod 14 is provided between two symmetrical support legs 13 at the front and back, and a transverse tie rod 15 is connected between two symmetrical support legs 13 on the left and right. The longitudinal tie rod 14 and the transverse tie rod 15 are provided to improve the overall stability of the frame 1.

[0056] Collection box 2 is located on top of the two horizontal tie rods 15 and is directly below the nursery mechanism 5.

[0057] The moving mechanism 3 includes a slide rail 31, a motor 32, a reciprocating screw 33 and a connecting plate 34. The slide rail 31 includes two slide rails, which are arranged symmetrically on the left and right. Two square sleeves are installed on the inner wall of each slide rail 31. Each square sleeve is fitted onto the corresponding end of the corresponding transverse tie rod 15. Each slide rail 31 is slidably connected to a movable sleeve.

[0058] The slide rail 31 is connected to the end of the transverse tie rod 15 on both sides to achieve its assembly with the frame 1, ensuring its ease of assembly and disassembly.

[0059] Motor 32 is mounted on the back wall of the rear transverse tie rod 15. Reciprocating screw 33 is located between the two transverse tie rods 15. The front end of reciprocating screw 33 is rotatably connected to the inner wall of the corresponding transverse tie rod 15 through a bearing. The rear end of reciprocating screw 33 passes through the corresponding transverse tie rod 15 and is mounted on the output end of motor 32. The connecting plate 34 is threaded onto the reciprocating screw 33, and both sides of the connecting plate 34 are fixedly connected to the corresponding movable sleeves.

[0060] When motor 32 is running, it drives the reciprocating screw 33 to rotate, and the two sides of the connecting plate 34 are connected to the corresponding moving sleeves, thereby realizing the linear movement of the connecting plate 34 during the rotation of the reciprocating screw 33.

[0061] The spraying mechanism 4 includes a side frame 41, a fertilizer spray pipe 42, a water spray pipe 43, and an extrusion component 44. There are two side frames 41, which are respectively installed on corresponding movable sleeves. Two supports are installed on the fertilizer spray pipe 42, and the side wall of each support is respectively installed on the inner shell wall of the corresponding side frame 41. Two carriers are installed on the water spray pipe 43, and the side wall of each carrier is respectively installed on the outer shell wall of the corresponding side frame 41. There are also two extrusion components 44, which are respectively installed on the corresponding side frames 41.

[0062] The external controller can be used to adjust the control valves connected to the fertilizer spray pipe 42 and the water spray pipe 43, thereby enabling watering and fertilization operations.

[0063] The extrusion component 44 includes a bent rod 441 that is bolted to the inner wall of the side frame 41, and a double-sided wedge 442 is welded to the other end of the bent rod 441.

[0064] Please see Figures 3-9 In this embodiment of the invention, the nursery mechanism 5 includes a seedbed 51 located on two square bars 11. A frame 52 is integrally provided on the inner wall of the seedbed 51. A mesh carrier plate 53 is installed on the top of the frame 52. The connection between the square bars 11 and the seedbed 51 can be varied. In this embodiment, a bolt connection is used.

[0065] Multiple protrusions are arranged in a matrix on the top shell wall of the mesh carrier plate 53. Each protrusion holds a cultivation pot 54 for cultivating seedlings. The protrusions adopt a hexagonal structure, which improves the stability of the cultivation pot 54. Multiple water-permeable holes are opened on the protrusions along the circumferential direction. The water-permeable holes penetrate the mesh carrier plate 53 to facilitate the drainage of excess liquid in the cultivation pot 54 and prevent water accumulation inside the cultivation pot 54.

[0066] Multiple U-shaped frames 55 are linearly arranged on the seedbed 51 to limit the cultivation pots 54. The U-shaped frames 55 are used to further limit and constrain the cultivation pots 54. The U-shaped frames 55 are connected to the seedbed 51 by screws, which facilitates disassembly and assembly.

[0067] The seedbed 51 is also linearly equipped with multiple pushing parts 56 for pushing the cultivation pots 54, and the bottom of the seedbed 51 is equipped with a sealing component 57.

[0068] The cultivation pot 54 includes a pot body 541. The bottom shell wall of the pot body 541 has an installation hole. The installation hole has a hexagonal structure to accommodate the protrusion. The top of the installation hole is integrally provided with a mesh plate 542 located inside the pot body 541. Above the mesh plate 542 is a movable plate 543 located inside the pot body 541. The movable plate 543 also has a perforated structure.

[0069] The bottom shell wall of the mesh disk 542 has a groove with a hole in the center. A shell cover 545 is installed in the groove by screws. A connecting rod 546 is provided in the shell cover 545. The top of the connecting rod 546 passes through the hole and is fixedly connected to the movable disk 543 by bolts. The bottom end of the connecting rod 546 passes through the bottom shell wall of the shell cover 545 and is threadedly connected to a push rod 547. A return spring is sleeved on the connecting rod 546. A circular groove is provided on the top shell wall of the movable disk 543. A protective cover 544 for covering the bolts is threadedly connected in the circular groove.

[0070] Each protrusion has a through hole at its center, which is used for the passage of the housing 545. The bottom end of the push rod 547 is connected to a ball bearing.

[0071] The pushing component 56 includes a shaft 561 located inside the seedbed 51. Both ends of the shaft 561 pass through the corresponding side walls of the seedbed 51. An end plate is installed at the front end of the shaft 561. A compression spring is sleeved between the end plate and the seedbed 51 on the shaft 561. A ball is rolled to the rear end of the shaft 561. Multiple conical pedestals 562 are linearly distributed on the shaft 561. Each conical pedestal 562 corresponds to a push rod 547.

[0072] When the pusher 56 is under force, each conical platform 562 on it applies force to the corresponding push rod 547 during the movement. After the push rod 547 is under force, it drives the corresponding moving disk 543 to move upward through the connecting rod 546. When the push rod 547 is no longer under force, the connecting rod 546 drives the moving disk 543 to move downward and reset under the action of the reset spring. At this time, the push rod 547 also resets.

[0073] Multiple drainage holes are linearly opened on the bottom shell wall of the seedbed 51. Each drainage hole is equipped with a sealing plug 571 for sealing. The bottom of the multiple sealing plugs 571 is connected to a support plate 572. The front and rear ends of the support plate 572 are equipped with contact members 573. The contact members 573 are in contact with the corresponding squeezing members 44. The contact member 573 is composed of a support rod and a ball. The ball is rolled and connected to the top of the support rod. When the spraying mechanism 4 is displaced, the squeezing member 44 on it applies force to the contact member 573, which causes the support plate 572 to move each sealing plug 571 downward, opening the seal on the drainage hole and facilitating the discharge of liquid accumulated in the seedbed 51.

[0074] Guide rods are installed on the front and rear sides of the top of the pallet 572. The top of each guide rod passes through the corresponding horizontal plate 12, and a reset spring 2 is sleeved on each guide rod. The reset spring 2 is set to facilitate the pallet 572 to drive the sealing plug 571 to reset.

[0075] Please see Figure 5and Figures 10-12 In this embodiment of the invention, the splicing frame 74 includes round rods 741 and I-shaped plates 742. There are four round rods 741, which are respectively disposed at the four bottom corners of the I-shaped plate 742. The I-shaped plate 742 is disposed on the output end of the electric push rod 72. The bottom ends of the four round rods 741 are all mounted on the straight plate 75.

[0076] The four round rods 741 enable the splicing frame 74 to stably drive the straight plate 75 to move up and down.

[0077] The straight plate 75 has five slots linearly opened for installing the corresponding circumferential cutting assembly 76. The circumferential cutting assembly 76 includes a ring 761 rotatably connected in the slot. The bottom of the ring 761 is provided with a connecting seat. A cutter 762 is installed on the connecting seat through a pin. The top of the outer ring of the ring 761 is provided with an external toothed ring 763. Multiple external toothed rings 763 mesh with each other.

[0078] The blade 762 adopts an arc-shaped cutter that fits the inner wall of the cultivation pot 54, which enables the circular cutting of the seedling roots in the cultivation pot 54. The arc-shaped cutter is double-edged to meet the reverse movement of different ring-cutting components 76 in the meshing state between multiple external toothed rings 763.

[0079] The blade 762 is provided with a scraping component 764 and a disinfection component 765 below it. The disinfection component 765 is located above the scraping component 764. Therefore, when the blade 762 moves upward, it will first pass through the scraping component 764 to clean impurities, and then be wiped and disinfected by the disinfection component 765.

[0080] The scraping component 764 includes two scraping plates, located on the left and right sides of the cutter 762 respectively. The disinfection component 765 includes two wiping plates, also located on the left and right sides of the cutter 762 respectively. The wiping plate on the left side is connected to the scraping plate by an integration plate, and the wiping plate on the right side is also connected to the scraping plate by an integration plate. A fixing rod 766 is welded to the integration plate on the right side.

[0081] The positioning component 77 includes a pressing plate 771, a movable rod 772, and a splicing plate 773. There are two movable rods 772, which are located on the front and rear sides of the top of the pressing plate 771, respectively. The top of both pressing plates 771 passes through the straight plate 75. The splicing plate 773 is disposed on the top of the two pressing plates 771. A return spring 3 located on the movable rod 772 is sleeved between the pressing plate 771 and the straight plate 75.

[0082] As the straight plate 75 moves downward, the positioning component 77 moves accordingly, and the pressing plate 771 in the positioning component 77 first contacts the cultivation basin 54. Then, as the straight plate 75 continues to move downward, the movable rod 772 of the positioning component 77 and the splicing plate 773 move upward, stretching the return spring three, while the pressing plate 771 continuously ensures the pressing limit on the cultivation basin 54.

[0083] The top of the fixing rod 766 passes through the corresponding ring 761 and is installed on the splicing plate 773. The left integrated plate is fixedly connected to the corresponding side wall of the pressing plate 771, thereby ensuring the relative stability of the position of the scraping part 764 and the disinfection part 765 when the fixing rod 766 moves synchronously with the lifting and lowering of the splicing plate 773.

[0084] Multiple nozzles for spraying disinfectant are linearly arranged on the pressing plate 771. The nozzles are connected to the liquid storage box 73 via hoses. Multiple liquid outlet pipes are provided on the left side shell wall of the liquid storage box 73. Each liquid outlet pipe is connected to the corresponding nozzle via a hose, and each liquid outlet pipe is equipped with a control valve.

[0085] The drive assembly 78 includes a pad that is fixedly connected to the rear bottom of the straight plate 75 by bolts. A second motor 781 is mounted on the pad. A gear 782 is mounted on the output end of the second motor 781. The gear 782 meshes with the external gear ring 763 in the rearmost ring cutting assembly 76.

[0086] When motor 781 is running, it drives gear 782 to rotate. Gear 782 meshes with the corresponding external gear ring 763 for transmission, and each external gear ring 763 meshes with each other, thereby realizing the rotational movement of each ring cutting component 76 through drive component 78.

[0087] The auxiliary component 79 includes a positioning rod 791 that is fixedly connected to the inner wall of the side of the support arm 71 by screws. A double-sided wedge 792 is installed at the bottom end of the positioning rod 791, and the double-sided wedge 792 makes rolling contact with the ball.

[0088] As the electric slide rail 6 drives the ring-cutting mechanism 7 to adjust its displacement, the double-sided wedge 792 in the auxiliary component 79 pushes and adjusts the pushing component 56 corresponding to the cultivation pot 54 that has completed the ring-cutting work, thereby lifting the seedlings and cultivation substrate in the corresponding cultivation pot 54, making it easier to remove the seedlings from the pot.

[0089] The working principle of this invention is as follows: When it is necessary to water or fertilize the seedlings on the planting bed, the motor 32 in the moving mechanism 3 is started by the external controller. The operation of the motor 32 drives the reciprocating screw 33 to rotate. At this time, the connecting plate 34 threaded to the reciprocating screw 33 moves. Since the two sides of the connecting plate 34 are respectively fixedly connected to the corresponding moving sleeve, the displacement adjustment in the front and back directions is carried out accordingly. When the moving sleeve is displaced, it synchronously drives the spraying mechanism 4 to move as a whole.

[0090] When the external controller starts the motor 32 in the moving mechanism 3, it simultaneously opens the corresponding external control valve, so that water or liquid fertilizer is released into the watering spray pipe 43 or fertilizer spray pipe 42 in the spraying mechanism 4. Then, during the overall movement of the spraying mechanism 4, the watering spray pipe 43 or fertilizer spray pipe 42 realizes the spraying treatment of water or liquid fertilizer on the seedlings in the nursery mechanism 5.

[0091] When the double-sided wedge 442 of the squeezing component 44 in the spraying mechanism 4 contacts the contact component 573 of the sealing component 57 in the nursery mechanism 5 during the movement, as the spraying mechanism 4 continues to move, the double-sided wedge 442 applies squeezing force to the corresponding contact component 573, thereby causing the support plate 572 in the sealing component 57 to move each sealing plug 571 down synchronously, stretching the reset spring 2. As each sealing plug 571 moves down synchronously, the corresponding drainage hole on the bottom shell wall of the seedbed 51 in the nursery mechanism 5 is opened, so as to release the liquid accumulated in the seedbed 51. The released liquid falls into the collection box 2 for collection.

[0092] When the double-sided wedge 442 leaves the contact 573, under the reset action of the reset spring 2, the support plate 572 drives each sealing plug 571 to move upward and reset synchronously, thereby sealing the corresponding drain hole again.

[0093] After the watering and fertilizing work is completed, the motor 32 in the external controller main body control moving mechanism 3 stops running after driving the spraying mechanism 4 to the initial position.

[0094] When it is necessary to transplant and remove seedlings from the various cultivation pots 54 in the nursery structure 5, the external controller first drives the electric slide rail 6 to move the ring cutting mechanism 7 to the appropriate position. Then the electric slide rail 6 stops and the electric push rod 72 in the ring cutting mechanism 7 is activated. The operation of the electric push rod 72 causes the splicing frame 74 to move down. The movement of the splicing frame 74 causes the straight plate 75 connected to it to move synchronously. As a result, the ring cutting component 76, positioning component 77 and driving component 78 on the straight plate 75 also move down.

[0095] During the downward movement, the pressing plate 771 in the positioning component 77 first contacts the top edge of the pot 541 in the cultivation pot 54 to be processed and presses it. With the electric push rod 72 running continuously, the movable rod 772 in the positioning component 77 drives the splicing plate 773 to move upward and compresses the reset spring three, thereby ensuring the continuous downward movement of the straight plate 75.

[0096] As the straight plate 75 continues to move downward, the bottom of the blades 762 in each ring-cutting component 76 first passes through the corresponding sterilization component 765 and scraping component 764, and then inserts into the interior of the basin 541 in the corresponding cultivation basin 54. The blades 762 are inserted along the edge of the basin 541. As the splicing plate 773 in the positioning component 77 moves upward during the continuous downward movement of the straight plate 75, it drives the fixing rods 766 in each ring-cutting component 76 to move, thereby ensuring the stable arrangement of the scraping component 764 and sterilization component 765 in each ring-cutting component 76.

[0097] After the insertion of the blade 762 in the ring-cutting assembly 76 is completed, the external controller body closes the electric push rod 72 and starts the motor 781 in the drive assembly 78. The gear 782 drives the external gear ring 763 in the last ring-cutting assembly 76 to move. The external gear ring 763 causes the ring 761 to move, which in turn causes the blade 762 located on the ring 761 to rotate. The external gear rings 763 in each ring-cutting assembly 76 mesh with each other, so that each ring-cutting assembly 76 can perform the ring-cutting operation on the root system of the seedling inside the corresponding cultivation pot 54.

[0098] The operation of motor 781 stops after the cutter 762 in each ring-cutting component 76 has rotated one revolution. At this time, the cutter 762 in each ring-cutting component 76 returns to its initial state. Then, the external controller starts the electric push rod 72 to retract, which drives the splicing frame 74 to move upward. The splicing frame 74 causes the straight plate 75 to move upward. In the initial stage of the upward movement of the straight plate 75, it drives each ring-cutting component 76 to move upward. Under the action of the reset spring 3, the pressing plate 771 in the positioning component 77 is still pressing the cultivation basin 54, and the movable rod 772 and the splicing plate 773 move downward.

[0099] During the upward movement of the ring-cutting component 76, its blade 762 is pulled out from the cultivation basin 54. During the extraction process, it first passes through the scraping component 764 to scrape and clean the impurities attached to it, and then is disinfected under the wiping of the disinfection component 765.

[0100] During the reset operation of the electric push rod 72, the control valves on the liquid storage box 73 are opened, so that the disinfectant in the liquid storage box 73 is also delivered to the corresponding nozzles under the action of the hose, thereby spraying and replenishing the disinfectant in the disinfection component 765 in the corresponding ring cutting assembly 76, ensuring its disinfection effect on the blade 762.

[0101] When the electric push rod 72 returns to its initial state, the positioning component 77 also returns to its initial state. Then the electric slide rail 6 runs for an appropriate distance again to perform ring cutting on the seedlings in the next set of cultivation pots 54. The displacement of the ring cutting mechanism 7, and the double-sided wedge 792 in the auxiliary component 79 pushes the pusher 56 corresponding to the cultivation pot 54 that has previously completed the ring cutting when the ring cutting mechanism 7 enters the next set of working positions.

[0102] After the pushing component 56 is subjected to force, it stretches and compresses the spring, and each of the conical platforms 562 moves forward, thereby pushing the push rod 547 in the corresponding cultivation pot 54. After the push rod 547 is subjected to force, it drives the connecting rod 546 to move upward, stretching the return spring. At this time, the moving plate 543 connected to the connecting rod 546 pushes the seedling and its cultivation substrate that have completed the ring cutting operation to move upward as a whole, further facilitating the staff to take the seedlings out of the pot for transplanting.

[0103] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
