Description

Technical Field

[0001] This utility model relates to the field of breeding and seedling technology, and in particular to a seedling bed for forestry engineering. Background Technology

[0002] In forestry seedling cultivation projects, seedbeds are crucial infrastructure for large-scale seedling cultivation. Traditional seedbeds typically employ a planar layout with multiple seedling pots. While this layout is simple and cost-effective, it reveals significant shortcomings in practical use. Because the seedling pots are arranged in a planar array on the bed, those in the middle and rear rows are far from the operator. When it's necessary to check the growth status, soil moisture, or pest and disease conditions of seedlings in specific rows (especially the rear rows), operators often need to walk around to the other side of the bed or lean in and bend over to observe, making the operation extremely inconvenient and laborious. For large-scale, multi-row, multi-column seedbeds, this inconvenience is further amplified, severely reducing the efficiency and convenience of seedling management. Furthermore, distant observation can easily lead to overlooking subtle changes in seedling growth, hindering the implementation of refined management. Therefore, a new type of seedbed for forestry engineering is proposed. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a seedling bed for forestry engineering.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a seedling bed for forestry engineering, comprising a bed body, on which several rows of seedling pots are arranged from left to right, and several seedling troughs for placing soil and seedlings are opened on the seedling pots. Each row of seedling pots has at least two seedling pots, and a pot support cylinder is provided between the bottom surface of each row of seedling pots and the platform surface of the bed body. The top surface of the pot support cylinder is open, and a rotating arm assembly is provided inside the pot support cylinder. The rotating arm assembly is connected to the seedling pots in the rear row, and the length of the rotating arm assembly gradually increases from the front row to the rear row. A drive assembly is provided inside the pot support cylinder to drive the rotating arm assembly to rotate forward around a fixed axis point. The drive assembly drives the rotating arm assembly to rotate, allowing the seedling pots in the rear row to rotate forward. The seedling trays are lifted and moved forward, changing the arrangement of a row of seedling trays from a laid-out layout to a stepped layout. The bed is equipped with a longitudinal guide component to guide the forward and backward sliding of the seedling trays, and a lifting guide component to guide the raising and lowering of the seedling trays. The longitudinal guide component and the lifting guide component keep the seedling trays flat and upward when they move. The drive component drives the rotating arm component to rotate, causing the seedling trays connected to it to be lifted and moved forward along a preset path. The entire row of seedling trays changes from a flat laid-out state to a stepped distribution with the front lower and the back higher. This allows the operator to stand on one side of the bed and have an unobstructed view of the inside of all the seedling trays in the row, greatly improving the convenience of inspection and management.

[0005] As a preferred technical solution of this utility model, the rotating arm assembly includes a fixed base, and the number of fixed bases is several and fixed inside the tray cylinder. The fixed base has an opening on its side and is rotatably connected to a first rotating shaft. The end of the first rotating shaft is fixedly connected to a hinge plate. The free end of the hinge plate has an opening and is rotatably connected to a connecting seat. The connecting seat is connected to the bottom surface of the seedling tray. Through the cooperation of the fixed base, the first rotating shaft, the hinge plate and the connecting seat, a stable rotating arm structure is constructed, which can accurately convert the rotational motion of the drive component into a composite motion of lifting and moving the seedling tray forward. The structure is simple and reliable.

[0006] As a preferred technical solution of this utility model, a locking shaft is connected to the side of the connecting seat located at the frontmost position. The free end of the locking shaft is fixedly connected to the tray cylinder. The locking shaft fixes the seedling tray and its connecting seat at the frontmost position to the tray cylinder, so that it remains stationary when the drive component is working.

[0007] As a preferred technical solution of this utility model, the driving component includes a gear ring connected to the outer wall of the first rotating shaft. A rack is provided on the bottom surface of the tray cylinder, and the top surface of the rack is provided with gear teeth corresponding to the position of the gear ring and meshes with the gear ring. A drive motor is installed inside the front side of the tray cylinder, and the drive shaft of the drive motor is connected to a lead screw. The front end of the rack is threadedly connected to the lead screw. The drive motor drives the lead screw to rotate, drives the rack to move back and forth, and drives each first rotating shaft to rotate synchronously through the gear ring, realizing the linkage of the entire row of rotating arm components. The power transmission is smooth, the synchronization accuracy is high, and it has a self-locking function, which can maintain the stepped state at any position.

[0008] As a preferred technical solution of this utility model, the longitudinal guide component includes a slide rail, which is connected to the table surface of the bed and located on one side of the seedling pot. A slide seat is slidably connected to the slide rail, and the slide seat is connected to the seedling pot. The cooperation between the slide rail and the slide seat provides precise linear guidance for the movement of the seedling pot in the front-back direction, and the movement trajectory is stable.

[0009] As a preferred technical solution of this utility model, the lifting guide assembly includes a multi-stage lifting rod, the bottom end of which is connected to a sliding seat, and the top end of which is connected to a seedling pot. The multi-stage lifting rod extends and retracts synchronously with the lifting and lowering of the seedling pot, providing stable support and guidance for the vertical movement of the seedling pot, ensuring that the seedling pot always maintains a horizontal posture during the lifting and lowering process, and preventing the soil and seedlings in the pot from tipping over.

[0010] As a preferred technical solution of this utility model, the top surface of the connecting seat is connected to a first positioning magnet, and the bottom surface of the seedling pot is connected to a second positioning magnet corresponding to the position of the first positioning magnet. The first positioning magnet and the second positioning magnet attract each other, thereby connecting the seedling pot to the connecting seat. The magnetic force is used to realize the quick connection and separation of the seedling pot and the connecting seat, which facilitates the individual handling and maintenance of the seedling pot, while ensuring the positioning accuracy during connection.

[0011] As a preferred embodiment of this utility model, the bottom surface of the seedling pot is provided with a sliding groove, and a sleeve rod is connected inside the sliding groove. A sliding hole is provided on the connecting seat and the sleeve rod is fitted with it. A return spring is fitted on the sleeve rod, and the end of the return spring abuts against the connecting seat. A pull groove for holding is provided on the front of the seedling pot. When it is necessary to observe a single seedling pot, the pull groove is pulled against the magnetic force, and the seedling pot slides along the sleeve rod and compresses the return spring, separating it from the connecting seat, allowing the seedling pot to move back and forth. After being released, under the action of the return spring, the seedling pot can automatically return to its original position and re-attach to the connecting seat by magnetic force. The operation is convenient and has an automatic reset function.

[0012] Compared with the prior art, the beneficial effects that this utility model can achieve are: 1. Through the coordinated action of the drive component, rotating arm component and guide component, the entire row of seedling pots can be switched from a flat laying state to a stepped observation state with one click, so that the operator can clearly observe all the seedling pots in the row without moving, which significantly improves the efficiency and convenience of seedling management.

[0013] 2. The longitudinal guide component and the lifting guide component ensure that the seedling pot has a precise movement trajectory and stable posture during the shape transformation process, avoiding soil spillage or seedling damage caused by the tilting of the pot.

[0014] 3. The magnetic structure and spring reset design make it easy and quick to adjust the position of a single seedling pot for observation, facilitating replacement or in-depth maintenance.

[0015] 4. The overall structure is compact, the drive is reliable, and the protection is adequate, making it suitable for long-term and stable operation in forestry seedling farms. Attached Figure Description

[0018] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation are all within the protection scope of this utility model without creative effort.

[0019] Example: Figure 1 and Figure 3 As shown, a seedling bed for forestry engineering includes a bed body 10. Several rows of seedling pots 11 are arranged parallel from left to right on the bed body 10. Each row contains at least two seedling pots 11 arranged one after the other. Each seedling pot 11 has multiple seedling troughs for placing soil and seedlings. A long strip-shaped pot support cylinder 12 is fixedly installed between the bottom surface of each row of seedling pots 11 and the platform surface of the bed body 10. The top surface of the pot support cylinder 12 is open.

[0020] like Figure 2 As shown, a rotating arm assembly is provided inside the tray cylinder 12. The rotating arm assembly includes multiple fixed seats 13, which are fixed at intervals along the length of the tray cylinder 12 on its inner bottom surface. Each fixed seat 13 has an opening on its side and is rotatably connected to a first rotating shaft 14. A hinge plate 15 is fixedly connected to the end of the first rotating shaft 14. A connecting seat 16 is rotatably connected to the free end of the hinge plate 15. The connecting seat 16 extends upward and is connected to the bottom surface of the corresponding seedling tray 11. Crucially, the lengths of the hinge plates 15 connecting different seedling trays 11 in the same row gradually increase from the front row to the back row. As the growth progresses, a locking shaft 21 is also connected to the side of the connecting seat 16 at the front. The free end of the locking shaft 21 is fixedly connected to the side wall of the tray cylinder 12 by means of threaded connection or welding. It should be noted that the locking shaft 21 fixes the seedling tray 11 and its connecting seat 16 at the front to the bed body 10. When the drive component drives each first rotating shaft 14 to rotate synchronously, the hinge plate 15 with increasing length will drive the connecting seat 16 and seedling tray 11 in the rear row in sequence, so that the lifting height and forward movement distance of their movement trajectory will increase one by one. This realizes the transformation from flat laying to a stepped shape with a lower front and a higher rear.

[0021] like Figure 3As shown, a drive assembly is also provided inside the tray cylinder 12. The drive assembly includes a gear ring 17 fixedly sleeved on the outer wall of each first rotating shaft 14, and a rack 18 laid flat on the inner bottom surface of the tray cylinder 12. The top surface of the rack 18 is provided with gear teeth that mesh with all the gear rings 17 simultaneously. A drive motor 19 is installed inside the front side of the tray cylinder 12. The drive shaft of the drive motor 19 is connected to a lead screw 20. The front end of the rack 18 is threadedly connected to the lead screw 20. It should be noted that when the drive motor 19 is working, it drives the lead screw 20 to rotate, thereby driving the rack 18 along the tray. The cylinder 12 moves back and forth along its length, and the rack 18 simultaneously meshes with the teeth at its top and drives all the gear rings 17, causing all the first rotating shafts 14 to rotate synchronously and in the same direction, thereby linking the entire row of rotating arm assemblies. This design achieves single-motor drive of the entire row of linkage, with good synchronization, and the screw and nut mechanism has self-locking properties, which can make the rotating arm assembly stably stay in any intermediate position, thereby locking the seedling pot 11 at the required stepped observation angle. In some embodiments, the drive motor 19 can be a stepper motor or a servo motor to achieve more precise position control.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the bed 10 is equipped with a longitudinal guide assembly and a lifting guide assembly. The longitudinal guide assembly includes a slide rail 22 fixed to the table surface of the bed 10 and parallel to the column direction, and a slide seat 23 slidably connected to the slide rail 22. The lifting guide assembly includes a multi-stage lifting rod 24, which is a known technology and consists of multiple rods of equidistantly reduced size that are progressively fitted together. The rods are retractable from each other, and their bottom ends are fixedly connected to the slide seat 23, while their top ends are fixedly connected to the bottom surface of the seedling pot 11. It should be noted that the cooperation between the slide rail 22 and the slide seat 23... The system strictly restricts the seedling pot 11 to move only along the front-back direction (i.e., the column direction) of the bed 10, preventing it from shifting laterally during the lifting process. The multi-stage lifting rod 24 extends and retracts synchronously with the lifting of the seedling pot 11, providing rigid guidance and support for the vertical movement of the seedling pot 11, ensuring that it remains horizontal at any height with the pot opening facing upwards. This effectively prevents the soil and seedlings inside the pot from spilling or being damaged due to the tilt of the pot. The synergistic effect of the longitudinal and lifting guide components decomposes the composite movement of the seedling pot 11 into two independent linear movements with precise and controllable trajectories.

[0023] like Figure 3 and Figure 4As shown, a first positioning magnet 25 is embedded in the top surface of the connecting seat 16, and a second positioning magnet 26 is embedded in the corresponding position on the bottom surface of the seedling pot 11. The two attract each other to achieve a quick connection between the seedling pot 11 and the connecting seat 16. Furthermore, a sliding groove is also provided on the bottom surface of the seedling pot 11, and a sleeve rod 27 is fixedly connected in the sliding groove. A sliding hole is provided on the connecting seat 16 and sleeve rod 27 is fitted on it. A return spring 28 is fitted on the sleeve rod 27. One end of the return spring 28 abuts against the bottom surface of the seedling pot 11, and the other end abuts against the connecting seat 16. A pull groove 29 is provided on the front surface of the seedling pot 11. It should be noted that, under normal conditions, the first positioning magnet... The attraction between the second positioning magnet 25 and the second positioning magnet 26 makes the seedling tray 11 stably attached to the connecting seat 16. When it is necessary to observe a certain seedling tray 11, simply pull the seedling tray 11 away from the connecting seat 16 through the pull groove 29, so that it slides along the sleeve rod 27 and compresses the return spring 28, which can overcome the magnetic force and separate it, thereby pulling the seedling tray 11 to slide. After being released, under the elastic force of the return spring 28, the seedling tray 11 automatically returns to its original position and re-attaches and fixes itself to the connecting seat 16. This design realizes the rapid movement and observation of the seedling tray, which greatly facilitates daily maintenance operations. In some embodiments, the return spring 28 can be a stainless steel compression spring.

[0024] like Figure 4 As shown, the left and right walls of the tray cylinder 12 are both designed as sloping surfaces. In some embodiments, a cover plate is detachably installed on its top surface by bolts. The cover plate has long through holes for structures such as the hinge plate 15 to pass through. It should be noted that the sloping wall provides more space for the internal mechanism and helps with air circulation and heat dissipation. The cover plate completely covers the precision mechanisms such as the rotating arm assembly and drive assembly, effectively preventing external factors such as watering and dust from causing pollution, corrosion or jamming, and improving the long-term operational reliability of the equipment in a humid seedling environment.

[0025] Working principle: Initially, all rows of seedling pots 11 are laid flat on the bed 10. When it is necessary to check a particular row, the drive motor 19 inside the pot support cylinder 12 of that row is started. The drive motor 19 drives the lead screw 20 to rotate, driving the rack 18 to move backward. The rack 18 drives all the gear rings 17 and the first rotating shaft 14 to rotate forward synchronously through the gear teeth. Starting from the second row, each hinge plate 15 rotates with the first rotating shaft 14, pushing the connecting seat 16 at its end and the connected seedling pot 11 to move. Since the length of the hinge plate 15 increases backward in succession, the seedling pots 11 in the later rows are lifted higher and moved further forward than those in the earlier rows. During this process, the longitudinal guide component guides the seedling pots 11. 1. The precise forward movement is guided by the lifting and guiding components to rise smoothly and remain horizontal. Ultimately, all the seedling pots 11 in the row are arranged in a stepped distribution, rising sequentially from front to back. The operator can stand on one side of the bed and clearly see the internal condition of each seedling pot 11 in the row without obstruction. After the inspection is completed, the drive motor 19 is started in reverse, and all the seedling pots 11 descend and move backward in sequence, returning to a flat state. Therefore, the core of this invention solves the problem of inconvenient observation of the rear row of traditional planar seedling beds. Through ingenious mechanical linkage and guiding design, a one-click convenient conversion of the seedling bed observation mode is realized, which greatly improves the efficiency and humanization of forestry seedling management.

[0026] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
