Description

Technical Field

[0001] This invention belongs to the field of factory planting technology, and more specifically relates to a plant factory planting device. Background Technology

[0002] Plant factory cultivation equipment is a modern agricultural equipment that achieves efficient and standardized plant cultivation by artificially controlling environmental parameters. Its core is to break free from dependence on the natural environment and achieve continuous production throughout the year. Its structure mainly includes an environmental control system, an artificial light system, a planting system, a nutrient solution supply system, a delivery system, and an intelligent monitoring terminal. The operation process is as follows: First, the equipment is debugged and the target parameters are set (such as temperature 20-25℃, light intensity 12-16h / d). Then, the pretreated seeds / seedlings are planted in the planting system. Subsequently, the environmental factors and nutrient solution supply are monitored and controlled in real time through the intelligent terminal. After the plants reach the harvest standard, they are harvested. At the same time, the planting system is cleaned and disinfected, and the next planting cycle begins.

[0003] In the planting process of a plant factory, holes of corresponding depth need to be made in the planting substrate first by pressing holes, and then seeds are sown into the holes to complete the sowing. The current mainstream hole-making structure is to use a motor to drive the pressing roller to rotate and open the holes. The pressing roller is integrally molded by injection molding. The mold cavity (i.e. the protrusion on the surface of the cylindrical cavity) is designed according to the depth and size of the target hole. PP / PE plastic granules are heated and melted into fluid and injected into the mold cavity. After the plastic cools and solidifies, it is demolded to obtain a pressing roller with the roller body and the surface pressing protrusions integrated.

[0004] However, different types of seeds have different requirements for hole depth. For example, large tomato seeds require 3cm deep holes, while small lettuce seeds only require 0.5cm deep holes. Alternatively, the sowing depth may vary depending on the light requirements of different seeds. The injection-molded one-piece pressing rollers mentioned above have fixed heights for the pressing protrusions, making it impossible to adjust the hole depth. The only way to adapt to the sowing needs of different seeds is to replace the pressing rollers with ones that match the hole depth. This method not only requires stocking pressing rollers of various specifications, increasing the procurement and storage costs of the equipment, but also requires stopping the planting production line for debugging when replacing the pressing rollers, which takes a lot of time and affects the continuity and efficiency of planting operations. Summary of the Invention

[0005] The present invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. The present invention primarily offers a plant factory planting device to solve the technical problem mentioned in the background section: the pressing rollers in current planting equipment are integrally molded using injection molding, resulting in a fixed height of the pressing protrusions, which can only accommodate one type of seed. This necessitates frequent shutdowns for replacement to accommodate different seeds, leading to low planting efficiency.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0007] A plant factory planting device includes a conveying mechanism for conveying planting trays. The conveying mechanism has a pressing area and a sowing area, each equipped with a rolling pressing mechanism and a corresponding rolling sowing mechanism. The rolling pressing mechanism includes a cylinder, a first end cap, and a second end cap, connected by bolts. The cylinder wall has multiple through holes spaced evenly along its length. A pressing adjustment component is installed inside the cylinder. The pressing adjustment component includes a limiting block and two drive discs located on either side of the limiting block. A connecting shaft is shared on both drive discs and passes through the limiting block. Multiple limiting grooves are spaced evenly on both sides of the limiting block. Each of the limiting grooves is provided with a sliding frame, and each of the drive discs is provided with guide ports at equal intervals, the same number as the limiting grooves. The guide ports are fitted onto the corresponding sliding frames. Two sliding frames in the same plane are connected by bolts to a pressing component. The rolling seeding mechanism includes a feeding cylinder filled with seeds and a feeding end cap. The feeding cylinder and the feeding end cap are connected by bolts. The cylinder wall of the feeding cylinder is provided with multiple outlet ports at equal intervals along its length. The positions of the outlet ports correspond one-to-one with the positions of the through holes. Each outlet port is provided with a discharge component. The feeding end cap and the second end cap are both provided with pulleys, and the two pulleys are connected by a belt.

[0008] Preferably, the cavitation component includes a push plate, on which a plurality of cavitation protrusions are linearly arranged at equal intervals, and each cavitation protrusion corresponds one-to-one with a through hole.

[0009] Preferably, the threaded positions at both ends of the connecting shaft are engaged with limit sleeves, which press against the corresponding drive discs.

[0010] Preferably, the outer wall of the limiting block is provided with a plurality of limiting protrusions at equal intervals, each of the limiting protrusions being engaged with a limiting groove, and the limiting grooves being distributed at equal intervals around the inner wall of the cylinder.

[0011] Preferably, a mounting bracket is bolted into the inner cavity of the cylinder, and a disc motor is mounted on the mounting bracket. The output end of the disc motor is connected to one end of a connecting shaft, and the other end of the connecting shaft is rotatably connected to a round hole on the first end cover.

[0012] Preferably, both the first end cover and the second end cover are rotatably connected to a first support frame, and the bearings in the two first support frames respectively cooperate with the connection between the first end cover and the second end cover. The first support frame is installed on the conveying mechanism by bolts.

[0013] Preferably, a servo motor is provided on one side of the outer wall of one of the first support frames, and the output end of the servo motor is connected to the interface on the second end cover.

[0014] Preferably, the discharge assembly includes an outlet head and a rotating cover. The outlet head and the outlet are connected by a thread. The outlet head is provided with a sliding opening and two first openings on the side near the rotating cover. The sliding opening is located at the edge of the outlet head. The two first openings are symmetrically distributed about the central axis of the outlet head. The rotating cover is provided with a connecting part, a receiving part, and two second openings. The connecting part and the outlet head are connected by a bearing. The receiving part and the sliding opening are slidably connected. The two second openings are symmetrically distributed about the central axis of the rotating cover.

[0015] Preferably, a reset torsion spring is fitted onto the connecting part, and the two ends of the reset torsion spring are respectively inserted into the round holes of the rotating cover and the guide head.

[0016] Preferably, a second support frame is provided on both the feeding cylinder and the feeding end cover. The bearings in the two second support frames are respectively engaged with the connection points of the feeding cylinder and the feeding end cover. The second support frames are installed on the conveying mechanism by bolts. A top opening member is provided on both second support frames. The top opening member includes a side frame. The side frame is installed on the side wall of the second support frame by bolts. Multiple top rods are linearly arranged at equal intervals on the side frame. Each top rod corresponds to a receiving part at the same height.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] (1) The present invention, through the setting of a cylinder, a first end cover, a second end cover, a mounting frame, a disc motor, a first support frame, a pressing hole control component, a limiting block, a drive disc, a connecting shaft, a sliding frame, a pressing hole component, a push plate, a pressing hole protrusion and a limiting sleeve, realizes that when opening holes in the substrate on the planting disc, the hole depth can be flexibly adjusted according to the seed type, which solves the defect of traditional pressing hole rollers that need to be replaced with different specifications to adapt to the hole depth of different seeds;

[0019] For example, when dealing with large / light-sensitive seeds, the disc motor drives the connecting shaft and drive disc to rotate. The curved structure of the drive disc guide port pushes the sliding frame to move along the limiting groove, thereby increasing the height of the pressing protrusion from the cylinder through hole, thus pressing out a deeper hole. When dealing with small / light-requiring seeds, the opposite adjustment can reduce the protrusion height of the pressing protrusion to form a shallow hole. Therefore, there is no need to replace the pressing roller, which saves the purchase and storage costs of pressing rollers of various specifications and avoids production line downtime for debugging due to pressing roller replacement. This effectively ensures the continuity of planting operations and significantly improves the operating efficiency of the planting process.

[0020] (2) By setting the first end cap, pulley, belt and feeding end cap, the present invention realizes the synchronous rotation of the cylinder in the rolling pressing mechanism and the feeding cylinder in the rolling sowing mechanism. With the conveying action of the conveying mechanism, after the pressing of the holes in the front row of substrate of the planting tray is completed, the feeding cylinder can be driven to rotate to the sowing area at the same time, which improves the linkage and coordination of the pressing and sowing steps and further improves the operating efficiency of the planting process.

[0021] Furthermore, the feeding cylinder, side frame, top rod, outlet head, first opening, sliding mouth, rotating cover, connecting part, receiving part, second opening, and reset torsion spring work together to ensure that when the discharging component rotates with the feeding cylinder above the hole, the top rod touches the receiving part, causing the second opening of the rotating cover to overlap with the first opening of the outlet head, so that the seeds fall accurately into the corresponding hole. After the discharging component leaves the sowing area, the reset torsion spring drives the rotating cover to close the discharging port, preventing the seeds from continuously scattering. This row-by-row synchronous sowing method ensures accurate seed supply to each hole, solves the problem of seeds scattering outside the hole in traditional broadcasting, and eliminates the need for additional sowing positioning equipment. It reduces seed waste while improving the uniformity of seedling transplanting and precise plant spacing, further optimizing the level of precision and standardization of planting operations.

Detailed Implementation

[0040] 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.

[0041] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0042] 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 specification of this 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.

[0043] For the implementation examples, please refer to the appendix. Figure 1-16 As shown, a plant factory planting device includes a conveying mechanism 1 for conveying planting trays 2. The conveying mechanism 1 has a pressing area 11 and a sowing area 12 respectively equipped with a rolling pressing mechanism 3 and a cooperating rolling sowing mechanism 5. The rolling pressing mechanism 3 includes a cylinder 31, a first end cap 32, and a second end cap 33, which are connected by bolts. The cylinder wall of the cylinder 31 has multiple through holes 311 arranged at equal intervals along its length. A pressing adjustment component 4 is provided inside the cylinder 31. The pressing adjustment component 4 includes a limiting block 41 and two drive discs 42. The drive discs 42 are located on both sides of the limiting block 41. A connecting shaft 43 is shared on both drive discs 42 and passes through the limiting block 41. Multiple limiting grooves 411 are arranged at equal intervals on both sides of the limiting block 41. Each limiting groove 411 is equipped with a sliding frame 44. The drive disc 42 is provided with guide ports 421 at equal intervals, the same number as the limiting grooves 411. The guide ports 421 are fitted onto the corresponding sliding frames 44. The two sliding frames 44 in the same plane are connected by bolts to a pressing element 45. The rolling seeding mechanism 5 includes a feeding cylinder 51 filled with seeds and a feeding end cover 52. The feeding cylinder 51 and the feeding end cover 52 are connected by bolts. The feeding end cover 52 can be connected to an external air pump to suck the seeds into the feeding cylinder 51, ensuring that the seeds are added without stopping the machine. The cylinder wall of the feeding cylinder 51 is provided with multiple outlet ports 511 at equal intervals along the length direction. The positions of the outlet ports 511 correspond one-to-one with the positions of the through holes 311. Each outlet port 511 is provided with a discharge component 6. The feeding end cover 52 and the second end cover 33 are both provided with pulleys 7, and the two pulleys 7 are connected by a belt.

[0044] The specific operation is as follows: First, select the depth of the holes in the substrate on the planting tray 2 according to the type of seed. If the seeds are large or light-sensitive, the holes should be deeper; conversely, if the seeds are small or light-sensitive, the holes should be shallower. Taking large seeds as an example, make deeper holes. Turn on the disc motor 35, and the disc motor 35 will drive the connecting shaft 43 to rotate. The connecting shaft 43 will simultaneously drive the two drive discs 42 to rotate on both sides of the limiting block 41 (the limiting block 41 is fixed inside the cylinder 31 and does not rotate with the drive discs 42). Then, the guide port 421 on the drive disc 42 will use its own... The curved structure changes, pushing the sliding frame 44 to slide on the limiting groove 411. That is, the limiting frame moves along the limiting groove 411 towards the edge of the limiting block 41. Every two sliding frames 44 on the same plane on the limiting block 41 jointly push the pressing member 45 to move outward. As a result, the part of the pressing protrusion 452 on the pressing member 45 protruding from the through hole 311 on the cylinder 31 increases. That is, the height of the pressing protrusion 452 exposed outside the cylinder 31 increases, so that when the substrate passes over the planting tray 2, a deeper hole is pressed out. After the height required by the seed is reached, the disc motor 35 stops running.

[0045] Then, using the conveyor belt on the conveyor mechanism 1 (existing conveyor equipment, so not described in detail), the front row of the planting tray 2 is moved to the pressing area 11 (that is, directly below the cylinder 31). At the same time, the servo motor 8 is turned on, and the servo motor 8 drives the cylinder 31 to rotate through the second end cover 33. The cylinder 31 then drives the pressing protrusion 452 on the pressing component 45 to perform a circular motion. The pressing protrusion 452 presses into each substrate in the front row of the planting tray 2 to form a hole. Then, the process is repeated row by row to open and press holes.

[0046] Since the second end cap 33 and the feeding end cap 52 are connected by a pulley 7 and a belt, during the rotation of the cylinder 31, the feeding end cap 52 drives the feeding cylinder 51 to rotate synchronously. As the conveying mechanism 1 conveys, the first row of pressed holes in the planting tray 2 will move to the sowing area 12, that is, below the feeding cylinder 51 (the feeding cylinder 51 is pre-filled with seeds). The bottom row of discharging components 6 on the feeding cylinder 51 is now positioned above the corresponding holes in the substrate. The receiving part 622 of the discharging component 6 contacts the front end of the push rod 532. As the feeding cylinder 51 continues to rotate with the discharging component 6, due to the pushing action of the push rod 532, the receiving part 622 pulls the rotating cover 62 along the sliding opening 612 to rotate around the connecting part 621, so that the rotation... The second opening 623 on the movable cover 62 gradually overlaps with the first opening 611 on the outlet head 61 (due to the position distribution of the top rod 532, the maximum deflection angle of the rotating cover 62 will be less than 90 degrees, so the second opening 623 and the first opening 611 will only partially overlap (only when deflected by 90 degrees can the first opening 611 and the second opening 623 completely overlap)). The reset torsion spring 63 is deformed by force, and the seeds flow out from the outlet 511 on the feeding cylinder 51, and then are scattered into the corresponding holes through the first opening 611 of the outlet head 61 and the second opening 623 of the rotating cover 62, achieving the purpose of precise sowing in each hole, avoiding the traditional technique of scattering seeds from above, which causes some seeds to fall onto the substrate outside the holes;

[0047] As the feeding cylinder 51 continues to rotate with the discharging component 6, the receiving part 622 continues to slide within the sliding opening 612. The contact point between the receiving part 622 and the push rod 532 gradually moves to the edge of the receiving part 622 until the receiving part 622 separates from the push rod 532. At this time, the reset torsion spring 63 drives the rotating cover 62 to reset, and the second opening 623 and the first opening 611 are misaligned, closing the discharging component 6 to prevent seeds from continuing to be scattered after the discharging component 6 has completely left the corresponding hole. The above steps are repeated to continuously sow seeds in the holes of the rear row.

[0048] Please refer to the appendix carefully. Figure 4-9As shown, the cavitation pressing component 45 includes a push plate 451, on which multiple cavitation pressing protrusions 452 are linearly arranged at equal intervals, and each cavitation pressing protrusion 452 corresponds one-to-one with a through hole 311. Through the cavitation pressing component 45, holes are opened and cavities are pressed into the entire row of substrate on the planting tray 2 one by one. The threaded positions at both ends of the connecting shaft 43 are engaged with limit sleeves 46. The limit sleeves 46 press against the corresponding driving disks 42, thereby limiting the axial movement of the driving disks 42 and preventing the driving disks from being driven. The wobbling of the drive disc 42 ensures that the sliding frame 44 can be stably moved during the rotation of the drive disc 42. The outer wall of the limiting block 41 is provided with multiple limiting protrusions 412 at equal intervals. Each limiting protrusion 412 is engaged with a limiting groove 312. The limiting grooves 312 are distributed at equal intervals around the inner wall of the cylinder 31. Through the cooperation between the limiting protrusions 412 and the limiting grooves 312, the limiting block 41 is constrained, preventing the limiting block 41 from rotating due to frictional contact with the drive disc 42.

[0049] The inner cavity of the cylinder 31 is bolted to a mounting frame 34, on which a disc motor 35 is mounted. The output end of the disc motor 35 is connected to one end of a connecting shaft 43, and the other end of the connecting shaft 43 is rotatably connected to a round hole on the first end cover 32. The disc motor 35 provides driving force for the rotation of the connecting shaft 43. The first end cover 32 and the second end cover 33 are both rotatably connected to a first support frame 36. The bearings in the two first support frames 36 respectively cooperate with the connection points of the first end cover 32 and the second end cover 33. The first support frames 36 are bolted to the conveying mechanism 1. The first support frames 36 enable the cylinder 31, the first end cover 32 and the second end cover 33 to be mounted on the conveying mechanism 1.

[0050] Please refer to the appendix carefully. Figure 2 and attached Figure 10-16As shown, a servo motor 8 is provided on one side of the outer wall of one of the first support frames 36. The output end of the servo motor 8 is connected to the interface on the second end cover 33. The servo motor 8 provides driving force for the rotation of the cylinder 31 and the feeding cylinder 51. The discharge assembly 6 includes an outlet head 61 and a rotating cover 62. The outlet head 61 and the outlet 511 are connected by a thread. The outlet head 61 has a sliding opening 612 and two first openings 611 on the side near the rotating cover 62. The sliding opening 612 is located at the edge of the outlet head 61. Two first openings 611 are symmetrically distributed around the central axis of the outlet head 61. The rotating cover 62 is provided with a connecting part 621, a receiving part 622 and two second openings 623. The connecting part 621 and the outlet head 61 are connected by a bearing, and the receiving part 622 is slidably connected to the sliding mouth 612. The two second openings 623 are symmetrically distributed around the central axis of the rotating cover 62. By gradually overlapping the second openings 623 on the rotating cover 62 with the first openings 611 on the outlet head 61, the discharge assembly 6 is opened, and the seeds are scattered in the corresponding holes.

[0051] A reset torsion spring 63 is fitted onto the connecting part 621. The two ends of the reset torsion spring 63 are respectively inserted into the round holes on the rotating cover 62 and the outlet head 61. Through the reset torsion spring 63, after the receiving part 622 and the top rod 532 separate, the rotating cover 62 is rotated back to its original position, meaning the second opening 623 and the first opening 611 are completely misaligned, closing the discharge assembly 6 and preventing seeds from spilling out. A second support frame 54 is provided on both the feeding cylinder 51 and the feeding end cover 52. The bearings inside the two second support frames 54 are respectively connected to the feeding cylinder 51 and... The feeding end cover 52 is connected and fitted. The second support frame 54 is bolted to the conveying mechanism 1. The two second support frames 54 are provided with a top opening member 53. The top opening member 53 includes a side frame 531. The side frame 531 is bolted to the side wall of the second support frame 54. Multiple top rods 532 are linearly arranged at equal intervals on the side frame 531. The top rods 532 correspond one-to-one with the receiving part 622 at the same height. By limiting the position of the top rods 532, the receiving part 622 pulls the rotating cover 62 to rotate.
