Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of forestry cultivation device, and particularly relates to a seedling cultivation device based on forestry engineering. BACKGROUND

[0002] With the development of modern forestry engineering technology, higher requirements are put forward for the stability and adaptability in the process of seedling cultivation. In the whole growth cycle of seedlings, the growth of the crown and root system of the seedlings is often not balanced, which leads to the continuous shift of the center of gravity of the seedlings, and further causes the overturning moment of the cultivation container, and finally leads to chronic tilting. This internal-external tilting will cause the root and stem to bear continuous unilateral pressure and shear stress, seriously interfere with the symmetrical development of the root system and nutrient absorption, and finally affect the survival rate and quality of the seedlings.

[0003] The existing seedling cultivation device mostly adopts rigid triangular supports or simple counterweight structures, and lacks linkage mechanism between the support components, and can only provide static support force in a fixed direction. When the container is tilted due to the unbalanced growth of the seedlings, the rigid support cannot dynamically adjust the support force distribution, and the fixed support point will be in opposition to the natural growth trend of the seedlings, which will aggravate the stress concentration phenomenon of the root and stem, and cannot fundamentally eliminate the overturning moment. This structural defect makes the seedlings face the risk of stress damage and developmental deformity in the growth process. Therefore, it is urgent to develop a seedling cultivation device based on forestry engineering to solve the problem that the existing device cannot respond to the dynamic growth of the seedlings.

As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0024] Referring to Figures 1-3 , the detailed description of a preferred embodiment of the present application: A seedling cultivation device based on forestry engineering, comprising: a seedling cultivation container 100, an anti-tilt platform 200, an integrated support 300, and a reset mechanism 400; the anti-tilt platform 200 is used to support the seedling cultivation container 100 and maintain its horizontal state; the integrated support 300 comprises a hinge shaft 301 and a plurality of support frames 302; the hinge portions 306 of the support frames 302 are connected by the hinge shaft 301 and are distributed circumferentially along the hinge shaft 301; each support frame 302 comprises an upper support rod 303 and a lower support rod 304; one end of the upper support rod 303 is connected to the hinge portion 306, and the other end is provided with a supporting portion 305, and a plurality of supporting portions 305 jointly enclose a support structure for the seedling cultivation container 100; one end of each lower support rod 304 is connected to the hinge portion 306, and the other end is provided with a slidable counterweight 312; the counterweight 312 is supported by the anti-tilt platform 200, and the counterweight 312 slides along the anti-tilt platform 200 with the lower support rod 304; the integrated support 300 is configured such that when the seedling cultivation container 100 tilts unilaterally, the unilateral corresponding support frame 302 links the counterweight 312 to move outward to balance the overall gravity of the tilted seedling; the reset mechanism 400 connects the plurality of support frames 302 to provide a force to cause the support frames 302 to approach or move away from the hinge shaft 301. The core function of the present application is to automatically perceive and balance the tilting of seedlings caused by uneven growth in real time through a purely mechanical structure, so as to realize self-adaptive balance adjustment of seedling growth.

[0025] When the seedling cultivation container 100 is tilted on one side, the pressure on the side support part 305 increases, forcing the corresponding support frame 302 to rotate around the hinge shaft 301, and through the lever action, the lower support rod 304 and the counterweight block 312 at the end thereof are linked and the counterweight block 312 is driven to slide outward on the anti-tilt platform 200 (the lower support rod 304 and the counterweight block 312 can be connected in a hinged manner, which allows the lower support rod 304 to rotate relative to the counterweight block 312 during swinging, thereby effectively avoiding the phenomenon of motion interference and jamming caused by rigid connection); the counteracting torque generated by the displacement of the counterweight block 312 can effectively balance the eccentric force caused by the tilting of the container; in this process, the reset mechanism 400 continuously provides a restoring force that causes the support frames 302 to move closer to each other, providing power for the system to return to the balanced state.

[0026] In implementation, first, the anti-tilt platform 200 is adjusted to be horizontal and fixed; then the seedling cultivation container 100 is placed on the support structure formed by the plurality of support parts 305; when the container tilts due to some reason, the device automatically operates according to the above principle, uses the sliding of the counterweight block 312 to offset the overturning torque, and the reset mechanism 400 assists the overall structure to return to the initial balanced position after the tilting force is eliminated, thereby realizing the stable cultivation of seedlings.

[0027] It can be understood that, based on the structure of the anti-tilt platform 200 supporting the seedling cultivation container 100 and maintaining its horizontal state, the horizontal stability of the seedling cultivation foundation is realized, providing a reference plane for the anti-tilt function; based on the structure of the plurality of support frames 302 connected in a circumferential direction by the hinge shaft 301 in the integrated support 300, and the lever-type layout of each support frame 302 composed of the upper support rod 303, the lower support rod 304 and the counterweight block 312, when the seedling cultivation container 100 tilts on one side, the corresponding side support frame 302 can automatically drive the counterweight block 312 on that side to slide outward through mechanical linkage, thereby balancing the eccentric torque generated by tilting by using the displacement of the counterweight block 312; based on the design of the reset mechanism 400 connecting the plurality of support frames 302 and providing a force that causes them to move closer to or away from the hinge shaft 301, the overall support is given the self-adaptive reset capability, which can assist each support frame 302 to restore the initial balanced state after the force changes. The device automatically senses and balances the tilting of seedlings in real time through pure mechanical structure, effectively improving the stability of seedling cultivation.

[0028] In addition, the seedling cultivation container 100 can be adapted to various shapes such as cylindrical and square slot, and only needs to be in effective abutment with the support part 305 of the support frame 302; the counterweight block 312 can be connected through the sliding block 205 guide rail 204, or directly in contact with the platform plane for sliding, and its moving track is locked by the hinge shaft 301; the reset mechanism 400 can adopt a tension spring connecting the counterweight block 312 and the center support column 206, or a torsional spring sleeved on the hinge shaft 301 to resist the support frame 302 by torsional arm, both of which provide a reset force for the system.

[0029] Preferably, the anti-tilt platform 200 is provided with a support plane 201, a ball head 202 and a ball seat 203; the support plane 201 supports the integrated support 300; the ball head 202 is installed at the bottom of the anti-tilt platform 200 and rotates with the swing of the support plane 201, and the ball head 202 is spherically hinged to the ball seat 203; the ball seat 203 is provided with a mounting plate 308 capable of being fixed to an external foundation. The core function of the anti-tilt platform 200 is to provide a low-friction resistance universal rotation fulcrum for the integrated support 300 above through its spherical hinge structure, so that the support and the seedling cultivation container 100 can freely and flexibly deflect when an external force or an unbalanced self-weight is applied, thereby providing a prerequisite for the balancing adjustment movement of the counterweight 312.

[0030] The anti-tilt platform 200 is mainly composed of a support plane 201, a ball head 202, a ball seat 203 and a mounting plate 308. The support plane 201 serves as a stable reference plane for supporting and guiding the sliding of the counterweight 312. The ball head 202 is fixedly installed at the geometric center of the bottom of the support plane 201, and the spherical structure below is nested in the ball seat 203, forming a spherical hinge fitting. The ball seat 203 is rigidly fixed to the external foundation through the mounting plate 308 provided at the bottom thereof.

[0031] When the seedling cultivation container 100 tilts for some reason, it will drive the integrated support 300 to rotate as a whole around the hinge axis 301. At this time, the counterweight 312 installed at the lower end of the support will slide on the support plane 201. The entire support, support plane 201 and ball head 202 will rotate as a whole around the hinge center of the ball head 202 and the ball seat 203, greatly reducing the rotary friction at the traditional fixed fulcrum, so that the counterweight 312 can be moved to the balanced position with extremely small resistance, thereby quickly and effectively offsetting the tilting moment.

[0032] It can be understood that, based on the structure of the anti-tilt platform 200 provided with the support plane 201, the ball head 202 and the ball seat 203, the spherical hinge fitting of the ball head 202 and the ball seat 203 enables the support plane 201 to realize multi-degree-of-freedom self-adaptive leveling, effectively absorbs and adapts to the unevenness of the foundation or the support surface, and significantly enhances the static stability of the seedling cultivation container 100 in complex environments; based on the plurality of buffer compression springs 208 distributed in the circumferential direction of the ball seat 203, the buffer compression springs 208 are connected and abut the ball seat 203 and the support plane 201 at both ends, respectively, and utilize the elastic buffering action of the compression spring to effectively suppress the vibration and impact from the external environment or the equipment operation, thereby further improving the anti-vibration performance and overall load stability of the anti-tilt platform 200. The structure realizes the dual functions of spherical hinge leveling and spring buffering, which together ensure the growth of the seedling cultivation container 100 in a high-stability and low-vibration interference environment.

[0033] In addition, liquid float level mechanism or multiple independent universal wheel mechanism can also be used as an alternative to the present design. Secondly, to prevent the ball head 202 and the ball seat 203 from tilting to one side in extreme cases, buffer compression springs 208 can be added around the ball seat 203. One end of each buffer compression spring 208 is connected to and abuts the ball seat 203, and the other end is connected to and supports the support plane 201, using the elastic limiting action of the spring to provide progressive damping and limiting protection for the deflection of the support plane 201.

[0034] Preferably, the anti-tilt platform 200 is also provided with multiple guide rails 204 and sliding blocks 205 that slide with the guide rails 204; each guide rail 204 is installed on the support plane 201 and extends in a direction that matches the swing trajectory of the corresponding lower support rod 304; the counterweight 312 is installed on the sliding block 205 and slides along the extension direction of the corresponding guide rail 204. The core function of this guide rail 204 sliding block 205 mechanism is to convert the free swing of the counterweight 312 into linear motion, providing stable guidance and support for it, ensuring that the counterweight 312 can efficiently and smoothly respond to the swing of the support, thereby quickly balancing the tilting moment.

[0035] The support plane 201 of the anti-tilt platform 200 is provided with multiple guide rails 204 that are evenly distributed around the center in the circumferential direction. The extension direction of each guide rail 204 is designed to point to the theoretical swing tangent direction at the hinge point of the corresponding lower support rod 304. A sliding block 205 that matches the cross section of the guide rail 204 is nested on the guide rail 204 and can slide along the length direction of the guide rail 204. The counterweight 312 is fixedly installed on the sliding block 205.

[0036] When the seedling container tilts and drives the lower support rod 304 to swing, the counterweight 312 connected to the lower support rod 304 will have a tendency to move. Under the action of the lever force, the counterweight 312 pushes the sliding block 205 to slide linearly in the direction of the pre-designed guide rail 204. This design restricts the possible disordered swing to directional linear displacement, greatly reducing the motion resistance and the risk of jamming, so that the counterweight 312 can move to the new equilibrium position more accurately.

[0037] It can be understood that the anti-tilt platform 200 is provided with a plurality of guide rails 204 and a slider 205 that slides with the guide rails 204, and the counterweight 312 is installed on the slider 205, which provides a linear guide and a stable support basis for the sliding of the counterweight 312; the design based on the extension direction of each guide rail 204 is adapted to the swing trajectory of the corresponding lower support rod 304, which ensures that the counterweight 312 can slide strictly in accordance with the lever movement direction of the support frame 302, effectively reducing the eccentric wear and jamming during the movement; the guide rail 204 slider 205 mechanism converts the free swing of the counterweight 312 into linear displacement, which significantly improves the response speed and movement smoothness of the counterweight 312 in the process of balancing the tilted gravity.

[0038] Preferably, the anti-tilt platform 200 is further provided with a central support column 206. The top end of the central support column 206 is connected to and supports the hinge shaft 301; the bottom end of the central support column 206 is connected to and supported by the support plane 201. The core function of the central support column 206 is to provide a centralized and stable support fulcrum for the hinge shaft 301 of the upper integrated bracket 300, ensuring that each support frame 302 can obtain support force in the height direction through this fulcrum.

[0039] The central support column 206 is a rigid column with its bottom end vertically fixed to the center of the support plane 201 of the anti-tilt platform 200, and its top end connected to the hinge shaft 301 of the integrated bracket 300. To further enhance the structural stability, a limiting structure that matches the shape of the hinge shaft 301 can be added to the top of the central support column 206, or a circumferential guide groove that matches the movement trajectory of each support frame 302 can be set. This design not only bears most of the vertical load of the bracket and the seedling container, but also provides effective limiting and guidance for the circumferential movement of each support frame 302 relative to the central support column 206, preventing each support frame 302 from radially offsetting during movement, and ensuring that all support frames 302 can rotate in a coordinated and synchronous manner around the central support column 206.

[0040] Preferably, the reset mechanism 400 is a tension spring; one end of the tension spring is connected to the counterweight 312 and slides with the counterweight 312, and the other end is connected to the central support column 206. The core function of the reset mechanism 400 is to provide a restoring force to the counterweight 312 after it moves, so that the entire support frame 302 system can automatically return to its initial equilibrium state after the external tilting force disappears.

[0041] The reset mechanism 400 adopts a tension spring, one end of which is connected to the counterweight 312, and the other end is connected to the central support column 206. In a balanced state, the tension spring is in a pre-stretched state, maintaining a certain initial tension.

[0042] When the counterweight 312 slides outward with the tilting movement, the tension spring is further stretched, storing elastic potential energy. When the external force causing the tilting disappears, the restoring force of the tension spring pulls the counterweight 312 to slide inward, driving the support frame 302 and the seedling cultivation container 100 back to the horizontal initial position, completing the automatic reset process.

[0043] Preferably, the central support column 206 is connected with the ball seat 203 through a threaded pair 207. The core function of this connection structure is to realize the height adjustment of the central support column 206, thereby flexibly adapting to seedling cultivation containers 100 of different specifications.

[0044] The bottom end of the central support column 206 is processed with external threads, and the top of the ball seat 203 is provided with a matching internal threaded hole. The two are connected through the threaded pair 207 to form a detachable rigid fixing structure. By rotating the central support column 206, the depth of the threaded pair 207 can be changed, thereby realizing the stepless adjustment of the height of the top end hinge shaft 301 of the support column. This adjustment can change the initial working angle of each support frame 302, and ultimately realize the adaptation to seedling cultivation containers 100 of different heights.

[0045] Preferably, the support frame 302 is provided with a plurality of positioning holes 307, a mounting plate 308 and a plurality of supporting bosses 309 on the supporting part 305; the plurality of positioning holes 307 are arranged in intervals along the length direction of the support frame 302; the mounting plate 308 is selectively matched with the plurality of positioning holes 307 through bolts, and the mounting plate 308 is adjustably mounted on the support frame 302; the plurality of supporting bosses 309 are arranged in intervals along the length direction of the mounting plate 308. The core function of this supporting part 305 structure is to realize the position adjustment of the mounting plate 308 on the support frame 302, and ultimately provide stable and adaptable support for seedling cultivation containers 100 of different sizes.

[0046] By selecting the mounting plate 308 to be fixed with positioning holes 307 of different heights, the height of the bottom support of seedling cultivation containers 100 of different sizes can be coarsely adjusted. When the number of distributed positioning holes 307 is limited, the plurality of supporting bosses 309 distributed in intervals on the mounting plate 308 can further adapt to the specific size distribution of the container bottom: when the container size is small, the inner side boss can be used for support; when the size is large, the outer side boss can be used for support, thereby realizing the fine adjustment of the supporting position. The supporting boss 309 of flexible material produces moderate elastic deformation when in contact with the container bottom, which not only ensures the stability of the support, but also avoids the problem that the abutting surface of the supporting boss 309 may not adapt to the bottom of seedling cultivation containers 100 of different sizes due to hard contact.

[0047] Preferably, the installation plate 308 is provided with side guards 310, which are arranged corresponding to the plurality of supporting bosses 309 and extend along the height direction of the seedling cultivation container 100. The core role of the side guards 310 is to act as a force transmission interface, which can instantly perceive the unilateral lateral force generated by the seedling cultivation container 100 due to tilting, and effectively transmit the force to the corresponding support frame 302.

[0048] The rigid side guards 310 are arranged on the installation plate 308, which are arranged corresponding to each supporting boss 309, and the plate body extends upward along the height direction of the seedling cultivation container 100, maintains a contactable spacing with the outer wall of the container, and forms a force transmission contact surface.

[0049] When the seedling cultivation container 100 tilts, the side wall thereof will contact the side guard 310 in the corresponding direction and apply a lateral pressure. The pressure is directly transmitted to the installation plate 308 through the side guard 310, and then acts on the corresponding support frame 302, converting into an initial torque that promotes the rotation of the support frame 302 around the hinge shaft 301, thereby starting the balance adjustment mechanism of the counterweight 312, and realizing the instant perception and response of the container tilting force.

[0050] Preferably, the supporting boss 309 is provided with an anti-skid structure 311. The core role of the anti-skid structure 311 is to increase the frictional resistance between the supporting boss 309 and the bottom of the seedling cultivation container 100, and prevent the container from sliding relative to the supporting surface.

[0051] The anti-skid structure 311 is arranged on the supporting surface of the supporting boss 309 in contact with the bottom of the container, which is made of concave-convex lines or high-friction coefficient materials. When the seedling cultivation container 100 is placed on the supporting boss 309, the anti-skid structure 311 is embedded in the micro-concave part of the container bottom through the surface protrusions, or forms a mechanical interlocking effect through the high-friction characteristics of the material itself, effectively inhibiting the displacement trend of the container in the horizontal direction, and ensuring that the container always maintains a stable relative position during the adjustment of the device.

[0052] Preferably, the anti-tilt platform 200 is also provided with a plurality of buffer compression springs 208 distributed circumferentially around the ball head 202; one end of each buffer compression spring 208 is connected to and abuts against the ball seat 203, and the other end is connected to and supports the support plane 201. The core role of the buffer compression spring 208 is to provide elastic buffering and limiting protection for the deflection movement of the support plane 201.

[0053] A plurality of buffer compression springs 208 are evenly distributed around the ball seat 203, and the lower end of each compression spring is fixedly connected to the ball seat 203, and the upper end is in contact with the lower surface of the support plane 201 and provides support. When the support plane 201 is deflected, the buffer compression springs 208 on the inclined side are compressed, generating a gradually increasing counter-supporting force, effectively absorbing impact energy and acting as a mechanical limiting function, ensuring that the support plane 201 always moves within a safe angle of inclination.

[0054] In summary, the device realizes the automatic balancing of the seedling cultivation container 100 based on the synergistic effect of the anti-inclination platform 200 and the integrated support 300. The platform provides low-friction support for the overall movement of the integrated support 300 above through the ball hinge structure, to adapt to the unbalanced state of the container, combined with the damping of the buffer compression spring 208, to ensure the stability of the foundation while self-adapting to the overall balance of the seedling; the support uses the principle of leverage to drive the counterweight 312 to slide along the guide rail 204 when the container is tilted, to balance the eccentric moment; the return spring automatically resets the counterweight 312. The center support column 206 enhances the overall overturning resistance, and its height is adjustable; the support part 305 adapts to different container sizes and prevents slipping and falling through the adjustable mounting plate 308 and the anti-slip boss. The self-adaptive balancing of the all-mechanical structure significantly improves the stability of the cultivation.
