Description

Technical Field

[0001] This invention relates to seed and seedling cultivation, specifically to the technical field of seedling transplanting equipment, and more specifically to an automated transplanting device for multi-layer three-dimensional cultivation. Background Technology

[0002] Multi-layer vertical cultivation is a highly efficient planting model that utilizes space. By constructing supports, cultivation troughs, and hanging devices, crops are transformed from flat planting to multi-layer, three-dimensional planting. It makes full use of vertical space and can be used to grow leafy vegetables and strawberries in greenhouses or herbs and lettuce on balconies. It can not only significantly increase the yield per unit area, but also save water and fertilizer and facilitate management, making it particularly suitable for urban agriculture and facility agriculture where land is scarce.

[0003] The automated transplanting device for multi-layer vertical cultivation is an automated device that replaces manual labor and enables precise transplanting of seedlings from seedling trays to multi-layer cultivation racks. It mainly includes a seedling supply mechanism for storing seedling trays, a seedling picking mechanism for grabbing / lifting seedlings, a conveying mechanism for transporting seedlings to each cultivation layer, a positioning mechanism for aligning the cultivation position, a seedling planting mechanism for planting seedlings into the substrate, and an electrical control system for controlling the coordinated operation of each component. In current automated transplanting devices, the seedling picking mechanism mainly uses two methods: top-down gripping and bottom-up lifting. For the gripping method, as described in application number 202510050835.6, an integrated clamping module is used, including a clamping unit and a clamping base. The clamping base is fixedly connected to a movable base, and several lifting units are located below the clamping base. The clamping unit includes a clamping block detachably connected to the lifting units. A clamping motor is installed inside the clamping block, and several clamping grooves are formed on the lower end face of the clamping block. Grippers are movably installed in the clamping grooves, and a crank is also installed inside the clamping block. The two ends of the crank are connected to the output end of the clamping motor and the grippers, respectively, thus completing the top-down gripping action. The other method is bottom-up lifting, which involves the tray contacting the bottom of the seedling tray. The seedlings are lifted from the bottom up and transferred to the multi-layer cultivation rack. However, both of these seedling-picking methods have obvious drawbacks when transplanting seedlings with tall stems (which generally have slender stems, low lignification, dense leaves, and a high center of gravity). When using the top-down gripping method, the grippers need to penetrate the dense leaves to contact the stem, which can easily cause leaf tearing and abrasion. Furthermore, the slender stems are prone to bending and breaking due to uneven force, and may even damage the stem base meristem. When using the bottom-up lifting method, although direct contact with the stem and leaves can be avoided, the center of gravity of tall seedlings shifts significantly upward. During the conveying, turning, or multi-layer lifting process, they are prone to swaying and tilting due to inertia. This may not only cause the root ball to fall off, but also result in the seedling tipping over or falling accidentally, causing mechanical damage to the seedling and affecting the subsequent seedling positioning accuracy. Summary of the Invention

[0004] This invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different approach. The seedling transplanting equipment of this invention pertains to seed and seedling cultivation and primarily offers an automated transplanting device for multi-layered, three-dimensional cultivation. This addresses the technical problem mentioned in the background section: current automated transplanting devices, particularly those using grasping or lifting methods, are unsuitable for transplanting tall plants, easily causing damage during the transplanting process.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: An automated transplanting device for multi-layer vertical cultivation includes a transplanting and seedling-retrieving mechanism that moves between a seedling rack and a multi-layer cultivation rack. This mechanism can move tall potted plants onto the multi-layer cultivation rack. The transplanting and seedling-retrieving mechanism includes a lifting platform with an installation opening.

A first mounting frame and a second mounting frame are provided on the mounting base. A first clamping plate is provided on the first mounting frame, and an adjustable clamping component is provided on the second mounting frame. The adjustable clamping component includes two parallel side plates. A seedling-retrieving area and a placement area are provided between the two side plates. The seedling-retrieving area includes multiple conveying sections, divided into a first conveying section, a second conveying section, and a third conveying section, with the conveying speed for tall potted plants gradually increasing.

[0006] Preferably, each of the conveying sections includes two first rotating shafts, the two ends of which are rotatably connected to the side plates. Each first rotating shaft is provided with a first pulley, and the two first pulleys are provided with a first conveyor belt.

[0007] Preferably, a speed-increasing gearbox is provided between the first rotating shafts on two adjacent conveying sections, and the outer casing of the speed-increasing gearbox is bolted to the side plate.

[0008] Preferably, the placement area includes two second rotating shafts, the two ends of which are rotatably connected to the side plate. Each second rotating shaft is provided with a second pulley, and the two second pulleys are provided with a second conveyor belt.

[0009] Preferably, one of the side plates is bolted together with two support frames and a connecting frame. The connecting frame is located in the middle of the side plate. Each of the two support frames is equipped with a first motor. The output ends of the two first motors are equipped with connecting shafts, and the two connecting shafts are respectively connected to the corresponding first rotating shaft and second rotating shaft.

[0010] Preferably, a plurality of second clamping plates are bolted between the two side plates, and the outer side of each second clamping plate is slidably engaged with the inner wall of the corresponding first conveyor belt or second conveyor belt, and the lower outer edge of the first conveyor belt and the second conveyor belt are provided with anti-slip folded edges.

[0011] Preferably, the mounting base is connected to the first mounting frame by bolts, and the groove on the mounting base and the protrusion at the bottom of the second mounting frame are slidably connected. The mounting base is also provided with a cylinder, and the output end of the cylinder is connected to the interface on the second mounting frame. Connecting bolts and matching connecting nuts are provided between the first mounting frame and the first clamping plate, and between the second mounting frame and the connecting frame.

[0012] Preferably, a sliding groove is provided on one side of the upper surface of the lifting platform, and the sliding groove is slidably connected to the protrusion on the lower side of the mounting base. A second motor is bolted to the lower side of the lifting platform. A first gear is provided at the output end of the second motor. The first gear is meshed with a second gear, and the second gear is located at one end of the first lead screw.

[0013] Preferably, the transplanting and seedling-taking mechanism further includes a support frame, on which a second lead screw and a slide rod are provided. A second nut seat is provided on the second lead screw, and a bracket is provided on both the second nut seat and the slide rod. The bracket is connected to the lifting platform by bolts. A third motor is connected to the top of the support frame by bolts, and the output end of the third motor is connected to the upper end of the second lead screw.

[0014] Preferably, the bottom of the stand is bolted to a base, and casters are provided at the four corners of the lower surface of the base.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The present invention, through the setting of a lifting platform, a first lead screw, a first nut seat, a stand, a second lead screw, a second nut seat, a slide bar, a bracket, a third motor, a base, a universal wheel, a second motor, a first gear, a second gear and a narrow belt side clamping mechanism, realizes the narrow belt clamping action, which acts on the side wall of the seedling pot of tall stem potted plants without contacting the stems and leaves of the seedlings. This effectively avoids the problems of stem bending, leaf tearing and stem base damage caused by the top-down grabbing method. At the same time, it solves the defects of shaking, tipping and soil ball falling off caused by the high center of gravity in the bottom-up lifting method. It significantly improves the integrity and survival rate of transplanting tall stem seedlings. Compared with the seedling grabbing and lifting methods in the prior art, it has played a revolutionary improvement. Furthermore, the coordination of the second motor, first gear, second gear, first lead screw, first nut seat, mounting seat, first mounting frame, second mounting frame, first clamping plate, cylinder, and adjustable clamping device allows the tall-stemmed potted plants to be directly transferred horizontally to the corresponding layer height of the multi-layer cultivation rack during transplanting, without the need for rotation to change direction. Unlike existing technologies, which require rotating the clamping seat to change direction (i.e., from the seedling rack to the multi-layer cultivation rack), this effectively avoids interference from the columns in the three-dimensional cultivation rack on the transplanting path. This allows the tall-stemmed potted plants to be placed close to the inside of the cultivation rack and around the columns, maximizing the utilization of each cultivation area and significantly improving the unit area utilization rate of the multi-layer three-dimensional cultivation rack, thus adapting to high-density cultivation needs.

[0016] (2) This invention, through the setting of side plates, second clamping plates, seedling taking area, placement area, connecting frame, first conveying section, second conveying section, third conveying section, first rotating shaft, first pulley, first conveyor belt, anti-slip folded edge, second rotating shaft, second pulley, second conveyor belt and speed-increasing gearbox, realizes that during the clamping and transplanting process, the seedling taking area composed of the first conveying section, second conveying section and third conveying section, under the speed control of the speed-increasing gearbox and the first motor, achieves the purpose of gradually increasing the transmission speed of each conveying section. When the tall stem potted plants pass through each conveying section in sequence, the distance between adjacent potted plants is widened, and the distance can be set in advance according to the growth characteristics, crown size and later growth space requirements of different tall stem plants (such as lucky bamboo, tall green pepper, etc.). The distance between adjacent tall stem potted plants can be flexibly adjusted, and it has a strong adaptability. This application solves the problems of competition for light and fertilizer and poor ventilation caused by the fixed spacing of traditional transplanting devices. It provides ample growing space for each tall plant, which is conducive to the expansion of the root system and the vigorous growth of stems and leaves, thereby improving the quality and yield of the crop. At the same time, for tall plants in small pots, multiple plants can be simultaneously clamped and transported by the cooperation of the first conveying section, the first clamping plate and the second clamping plate, which simplifies the operation process and saves transplanting time. It can be achieved by simply adjusting the motor speed. It is suitable for the transplanting needs of different types and sizes of tall plants, thus broadening the application range of the device.

[0020] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the accompanying drawings, which illustrate several embodiments of the present invention. However, the present invention can be implemented in different forms and is not limited to the embodiments described in the text. Rather, these embodiments are provided to make the disclosure of the present invention more thorough and complete.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly associated with those skilled in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] Example 1, please refer to the appendix for details. Figure 1-13 As shown, an automated transplanting device for multi-layer vertical cultivation includes a transplanting and seedling-retrieving mechanism 3 that moves between a seedling rack 1 and a multi-layer cultivation rack 2. The transplanting and seedling-retrieving mechanism 3 can move tall-stemmed potted plants 11 onto the multi-layer cultivation rack 2. The transplanting and seedling-retrieving mechanism 3 includes a lifting platform 31 with an installation port 311. A first lead screw 32 and a first nut seat 321 on the first lead screw 32 are disposed within the installation port 311. The first nut seat 321 slides within the installation port 311. A narrow-band side clamping mechanism 4 is provided on the nut seat, and the narrow-band side clamping mechanism 4 includes a mounting base 41. The mounting base 41 and the first nut seat 321 are connected by bolts. The mounting base 41 is provided with a first mounting frame 411 and a second mounting frame 412. The first mounting frame 411 is provided with a first clamping plate 42. The second mounting frame 412 is provided with an adjustable clamping member 5. The adjustable clamping member 5 includes two parallel side plates 51. A seedling picking area 52 and a placement area 521 are provided between the two side plates 51. The seedling picking area 52 includes multiple conveying sections and is divided into a first conveying section 53, a second conveying section 54 and a third conveying section 55. The conveying speed of the tall stem potted plant 11 gradually increases.

[0024] The above structure enables the side clamping of the seedling pots of tall-stemmed potted plants 11 during transplanting, avoiding damage to the seedling stems and leaves. Horizontal transplanting does not require turning, avoiding interference with the columns of the multi-layer cultivation rack 2, and greatly improving space utilization. In addition, the multi-stage speed-up conveying structure allows for adjustment of the spacing between adjacent pots as needed, adapting to the growth needs of different tall-stemmed plants, ensuring sufficient growth space to improve survival rate and yield, while simplifying operation and broadening the applicability of the device.

[0025] The specific operation is as follows: First, the entire device is moved between the seedling rack 1 and the multi-layer cultivation rack 2 using the universal wheels 381. Then, the third motor 37 is turned on, driving the second lead screw 34 to rotate. Subsequently, with the cooperation of the second nut seat 341 and the slide rod 35 on the second lead screw 34, the lifting platform 31 is moved down by the bracket 36, so that the upper side of the lifting platform 31 is flush with the upper side of the seedling rack 1. Then, the second motor 39 is turned on, and with the cooperation of the first gear 391 and the second gear 392, the first lead screw 391 is driven to rotate. When rod 32 rotates, the first nut seat 321 on the first lead screw 32 drives the narrow-band side clamping mechanism 4 to move closer to the corresponding row of tall stem potted plants 11, so that the row of tall stem potted plants 11 is located between the first clamping plate 42 and the adjustable clamping member 5. At the same time, the cylinder 43 is activated, driving the adjustable clamping member 5 to move closer to one side of the first clamping plate 42 and to contact the seedling pot of the tall stem potted plant 11. This avoids the top-down grabbing or bottom-up lifting in the prior art, and will not cause damage to the leaves or tipping problems due to instability of the center of gravity. When the first motor 61 on the two side plates 51 is turned on, the two first motors 61 drive the first rotating shaft 56 and the second rotating shaft 57 to rotate respectively through the connecting shaft 62. In the seedling picking area 52, the first rotating shaft 56, the first pulley 561, the first conveyor belt 562 and the speed-increasing gearbox 59 cooperate to form the first conveying section 53, the second conveying section 54 and the third conveying section 55 with gradually increasing transmission speed. In the placement area 521, the second rotating shaft 57 drives the second conveyor belt 58 to move through the second pulley 571. Therefore, during the process of driving the narrow-band side clamping mechanism 4 to approach the corresponding row of tall-stemmed potted plants 11, the tall-stemmed potted plants 11 located on the outermost side of the row will first enter the first conveying section 53 of the seedling area 52, and then the other tall-stemmed potted plants 11 in the row will follow one by one (for tall-stemmed plants in small pots, such as lucky bamboo, multiple plants can be clamped at once using the first conveying section 53 and the first clamping plate 42, without having to enter the conveying section one by one). After passing through the first conveying section 53, the tall-stemmed potted plants 11 will then pass through the second conveying section 54 and the third conveying section 55 in sequence. By controlling the speed of the first motor 61 connected to the first rotating shaft 56, the distance between each pair of adjacent tall-stemmed potted plants 11 can be controlled after passing through the three conveying sections. This allows sufficient growth space to be reserved in advance according to the type of tall-stemmed plant, which is beneficial for later growth. After all the tall-stemmed potted plants 11 have passed through the third conveyor section 55, they will be evenly distributed between the second conveyor belt 58 and the first clamping plate 42. Then, the first motor 61 connected to the second rotating shaft 57 will be turned off, and the third motor 37 will drive the second lead screw 34 to rotate again, adjusting the height of the tall-stemmed potted plants 11 in the placement area 521 on the narrow belt side clamping mechanism 4. After the corresponding height is determined, the second motor 39 will drive the first gear 391 to reverse. Subsequently, under the action of the second gear 392, the first lead screw 32 will reverse. The first nut seat 321 on the first lead screw 32 will move the tall-stemmed potted plants 11 on the placement area 521 to the corresponding layer height of the cultivation rack through the mounting seat 41. Then, the cylinder 43 will pull the adjusting clamping part 5 to reset, releasing all the tall-stemmed potted plants 11 in the row, thus completing the transplanting of the tall-stemmed potted plants 11 in the row.

[0026] Example 2, please refer to the appendix for details. Figure 2 and attached Figure 7-13 As shown, each conveying section includes two first rotating shafts 56, with both ends of the first rotating shafts 56 rotatably connected to the side plate 51. Each first rotating shaft 56 is equipped with a first pulley 561, and a first conveyor belt 562 is shared by the two first pulleys 561. A speed-boosting gearbox 59 is provided between the first rotating shafts 56 of adjacent conveying sections, and the housing of the speed-boosting gearbox 59 is bolted to the side plate 51. The conveying section is connected to the first rotating shaft 56, the first pulley 561, the first conveyor belt 562, and the speed-boosting gearbox 59. The cooperation between the speed gearboxes 59 forms multiple conveying sections with progressively increasing conveying speeds. The placement area 521 includes two second rotating shafts 57. The two ends of the second rotating shafts 57 are rotatably connected to the side plates 51. Each second rotating shaft 57 is equipped with a second pulley 571. The two second pulleys 571 are jointly equipped with a second conveyor belt 58. Through the cooperation between the second rotating shafts 57, the second pulleys 571, and the second conveyor belt 58, the tall stem potted plants 11 in the placement area 521 are arranged and unfolded at equal intervals. Two support frames 6 and a connecting frame 522 are bolted to one of the side plates 51. The connecting frame 522 is located in the middle of the side plate 51. Each of the two support frames 6 is equipped with a first motor 61, and the output end of each of the two first motors 61 is equipped with a connecting shaft 62. The two connecting shafts 62 are respectively connected to the corresponding first rotating shaft 56 and second rotating shaft 57. Through the cooperation between the first motors 61 and the connecting shafts 62, driving force is provided for the rotation of the first pulley 561 and the second pulley 571. Multiple second clamping plates 511 are bolted together between the plates 51. The outer side of each second clamping plate 511 slides and engages with the inner wall of the corresponding first conveyor belt 562 or second conveyor belt 58. This effectively prevents the first conveyor belt 562 and the second conveyor belt 58 from deforming under force during the clamping and conveying process, thus preventing instability in the clamping. Furthermore, the lower outer edges of the first conveyor belt 562 and the second conveyor belt 58 are provided with anti-slip folded edges 563 to prevent accidental slippage during the movement of the tall stem potted plant 11, thus providing a bottoming effect. The mounting base 41 is connected to the first mounting frame 411 by bolts. The groove on the mounting base 41 is slidably connected to the protrusion at the bottom of the second mounting frame 412. The mounting base 41 is also provided with a cylinder 43, and the output end of the cylinder 43 is connected to the interface on the second mounting frame 412. The cylinder 43 provides driving force for the movement of the adjustable clamping member 5. Connecting bolts 44 and matching connecting nuts 45 are provided between the first mounting frame 411 and the first clamping plate 42, and between the second mounting frame 412 and the connecting frame 522. The connection between the first mounting frame 411 and the first clamping plate 42 and the connection between the second mounting frame 412 and the connecting frame 522 are realized through the cooperation between the connecting bolts 44 and the connecting nuts 45.

[0027] Example 3, please refer to the appendix for details. Figure 3-6 and attached Figure 9As shown, a sliding groove 312 is provided on one side of the upper surface of the lifting platform 31. The sliding groove 312 is slidably connected to the protrusion on the lower side of the mounting base 41, ensuring the stability of the mounting base 41 in moving on the lifting platform 31. A second motor 39 is bolted to the lower side of the lifting platform 31. A first gear 391 is provided at the output end of the second motor 39. The first gear 391 is meshed with a second gear 392, and the second gear 392 is located at one end of the first lead screw 32. Through the cooperation between the second motor 39, the first gear 391, and the second gear 392, the driving force for the rotation of the first lead screw 32 is realized. The transplanting seedling picking mechanism 3 also includes The device includes a support frame 33, on which a second lead screw 34 and a slide rod 35 are mounted. A second nut seat 341 is mounted on the second lead screw 34. A bracket 36 is mounted on both the second nut seat 341 and the slide rod 35. The bracket 36 is connected to the lifting platform 31 by bolts. A third motor 37 is bolted to the top of the support frame 33. The output end of the third motor 37 is connected to the upper end of the second lead screw 34, providing driving force for the rotation of the second lead screw 34. A base 38 is bolted to the bottom of the support frame 33. Universal wheels 381 are mounted at the four corners of the lower surface of the base 38, facilitating the movement and turning of the entire device.
