Description

Technical Field

[0001] This utility model relates to the field of plant cultivation technology, and in particular to a plant cultivation rack. Background Technology

[0002] To make efficient use of space, planters are often placed on multi-layered cultivation racks. Therefore, using cultivation racks to cultivate plants is a common cultivation method that is widely used in the cultivation of fruits, vegetables, and garden plants.

[0003] Patent CN214758119U discloses a plant cultivation rack. In this design, a cultivation pot containing a plant is placed into a storage slot on a cultivation base. The outer wall of the cultivation pot abuts against a first limiting plate and a second limiting plate, thereby compressing a first spring and a second spring. When the cultivation pot is completely placed into the storage slot, the first limiting plate and the second limiting plate, through the rebound force of the first spring and the second spring, firmly abut against the outer wall of the cultivation pot, thereby fixing the cultivation pot in the storage slot. The cultivation base is also connected to the storage rack, which improves the stability of the cultivation pot placed on the cultivation rack.

[0004] When the above-mentioned plant cultivation rack is in use, the cultivation base is supported by the storage rod. However, the storage rod is fixed inside the rack and the height of the plant rack cannot be adjusted. Therefore, the space cannot be adjusted according to the growth stage or variety of the plant, resulting in the upper layer blocking the lower layer or insufficient height of the rack squeezing the plant growth, and low space utilization. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a plant cultivation rack to solve the problem that the plant cultivation rack cannot adjust the layer height and squeezes the plant growth.

[0006] This utility model provides a plant cultivation rack including a base, a third servo motor fixedly embedded in the bottom of the base, and a turntable rotatably mounted on the upper end of the base. The turntable is fixedly connected to the output end of the third servo motor. The feature is that a limit frame is rotatably mounted on the upper end of the turntable, and the rack further includes:

[0007] A longitudinal spacing adjustment mechanism is installed inside a limiting frame;

[0008] A cultivation limiting mechanism, wherein there are multiple cultivation limiting mechanisms, and the cultivation limiting mechanism is installed at the front end of a longitudinal spacing adjustment mechanism, wherein the longitudinal spacing adjustment mechanism is used to adjust the longitudinal spacing of the multiple cultivation limiting mechanisms;

[0009] A support mechanism is installed at the rear of the upper end of the turntable, and the support mechanism is used to support the limiting frame.

[0010] Preferably, the upper ends of both sides of the rear end of the limiting frame are provided with a second sliding groove, and the front ends of both sides of the limiting frame are provided with a first sliding groove. The internal shape of the first sliding groove and the second sliding groove is T-shaped.

[0011] Preferably, the longitudinal spacing adjustment mechanism includes a first limiting seat and a fixing plate. The first limiting seat is fixedly connected to the upper rear end of the limiting frame and is located in the middle of the rear end of the limiting frame. The fixing plate is fixedly connected to the lower rear end of the limiting frame. A collar is provided in the middle of the fixing plate. A first threaded rod is rotatably installed in the collar and the first limiting seat. A first servo motor is fixedly installed at the upper end of the first limiting seat. The first threaded rod is fixedly connected to the output end of the first servo motor. A lifting movable bar is threadedly installed on the outer side of the first threaded rod. A first T-block is fixedly installed on both sides of the front end of the lifting movable bar. The first T-block is movably locked in the second slide groove, and the shape of the first T-block matches the shape of the second slide groove. A scissor-type lifting rod is rotatably installed on the front end of the fixing plate and the lifting movable bar, and the fixing plate and the lifting movable bar are located at the upper and lower rear ends of the scissor-type lifting rod.

[0012] Preferably, each of the plurality of cultivation limiting mechanisms includes a rectangular frame. The rectangular frame is installed at the front end of the scissor lift connection, and the connecting shaft of the scissor lift is rotatably connected to the rectangular frame. The plurality of rectangular frames are arranged in a longitudinal array at the front end of the limiting frame. The rectangular frame is provided with a plurality of rectangular limiting grooves arranged in a transverse array. Fixed shafts are fixedly installed on the upper ends of both sides of the rectangular limiting grooves. Cultivation seats are rotatably installed on the inner side of the fixed shafts. A counterweight is fixedly installed on the lower end of the cultivation seats. Second T-shaped blocks are fixedly installed on both sides of the rear end of the rectangular frame. The second T-shaped blocks are movably locked in the first sliding groove, and the shape of the second T-shaped blocks is adapted to the shape of the first sliding groove.

[0013] Preferably, the support mechanism includes two second limiting seats, which are fixedly connected to the upper rear part of the turntable and arranged longitudinally. A second threaded rod is rotatably installed inside the second limiting seat. A second servo motor is fixedly installed on the upper rear part of the rear end of the second limiting seat. The output end of the second servo motor is fixedly connected to the second threaded rod. A threaded block is threadedly installed on the outer side of the second threaded rod. A support connecting rod is rotatably connected to the upper end of the threaded block. The end of the support connecting rod away from the threaded block is rotatably connected to the lifting movable bar.

[0014] Preferably, a solar panel is fixedly installed on the upper end of the limiting frame, and a storage battery is fixedly installed on the upper right side of the limiting frame. The storage battery is electrically connected to the solar panel, the first servo motor, the second servo motor, and the third servo motor.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model, through the design of a longitudinal spacing adjustment mechanism, allows for flexible adjustment of the layer height according to the plant growth stage or variety. After the first servo motor is started, its output end drives the first threaded rod to rotate within the collar of the first limiting seat and the fixed plate. Because the lifting movable bar is threadedly connected to the first threaded rod and is locked in the second slide groove by the first T-block, the rotation of the first threaded rod will drive the lifting movable bar to move longitudinally along the second slide groove, thereby driving the scissor-type lifting rod to extend and retract. When the scissor-type lifting rod extends and retracts, the cultivation limiting mechanism at the front end of its connection will move longitudinally synchronously along the first slide groove through the second T-block, realizing precise adjustment of the longitudinal spacing of multiple cultivation limiting mechanisms. This design can completely avoid the situation where the upper layer blocks the lower layer space and the insufficient layer height squeezes the plant growth, allowing the cultivation rack space to adapt to the growth needs of different plants and greatly improving the space utilization rate.

[0017] 2. This utility model uses a third servo motor inside the base to drive the turntable to rotate. The turntable synchronously drives the limiting frame and all cultivation limiting mechanisms to rotate as a whole, ensuring that the plants on each layer of cultivation seats can receive light evenly and maintain balanced plant growth. At the same time, during the longitudinal spacing adjustment, the support mechanism operates synchronously, and the support connecting rod provides dynamic support to the lifting movable bar, offsetting the tilting force generated by the cultivation limiting mechanism and the weight of the plants on the limiting frame. Meanwhile, the cultivation seat is rotatably connected by a fixed shaft and has a counterweight at the lower end, which can always maintain a horizontal state and prevent the cultivation substrate from tilting and spilling. This dual protection ensures the light conditions required for plant growth and avoids the risk of tilting of the cultivation rack structure and spillage of cultivation substrate during the adjustment process, thus improving the stability and reliability of the cultivation process.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] like Figure 1-4 As shown, this utility model has the following two specific embodiments.

[0026] Example 1

[0027] A plant cultivation rack includes a base 1, with a third servo motor fixedly embedded in the bottom of the base 1, and a turntable 2 rotatably mounted on the upper end of the base 1. The turntable 2 is fixedly connected to the output end of the third servo motor. The rack is characterized by having a limit frame 3 rotatably mounted on the upper end of the turntable 2, and further includes:

[0028] Longitudinal spacing adjustment mechanism 4 is installed inside the limiting frame 3;

[0029] The cultivation limiting mechanism 5 is a multiple cultivation limiting mechanism 5. The cultivation limiting mechanism 5 is installed at the front end of the longitudinal spacing adjustment mechanism 4. The longitudinal spacing adjustment mechanism 4 is used to adjust the longitudinal spacing of the multiple cultivation limiting mechanisms 5.

[0030] Support mechanism 6 is installed at the upper rear of turntable 2 and is used to support limit frame 3.

[0031] In this embodiment, as Figures 1-4As shown, when this plant cultivation rack is working, the third servo motor at the bottom of the base 1 is started first. Its output end drives the turntable 2, which is fixedly connected to it, to rotate on the upper end of the base 1. During the rotation of the turntable 2, the upper-mounted limiting frame 3 and the longitudinal spacing adjustment mechanism 4, cultivation limiting mechanism 5, and support mechanism 6 on the limiting frame 3 are rotated as a whole, so that the plants on the multiple cultivation limiting mechanisms 5 can receive light evenly. When it is necessary to adjust the layer height according to the plant growth stage or variety, the longitudinal spacing adjustment mechanism 4 is activated. It drives multiple cultivation limiting mechanisms 5, which are arranged in a longitudinal array, to move longitudinally along the limiting frame 3 through the internal transmission structure, thereby flexibly changing the longitudinal spacing between adjacent cultivation limiting mechanisms 5, avoiding the problem of the upper layer blocking the lower layer or insufficient layer height squeezing the plant growth. During this process, the support mechanism 6 operates synchronously. It supports the rear end of the limiting frame 3 through the connection structure with the upper rear of the turntable 2, offsetting the tilting force generated by the weight of the cultivation limiting mechanisms 5 and the plants on the limiting frame 3, and ensuring the stability of the entire cultivation rack structure during adjustment and use.

[0032] Example 2

[0033] The difference from Embodiment 1 is that this embodiment discloses a longitudinal spacing adjustment mechanism 4, a cultivation limiting mechanism 5, and a support mechanism 6:

[0034] The upper ends of both sides of the rear end of the limiting frame 3 are provided with a second sliding groove 32, and the front ends of both sides of the limiting frame 3 are provided with a first sliding groove 31. The internal shape of the first sliding groove 31 and the second sliding groove 32 is T-shaped.

[0035] The longitudinal spacing adjustment mechanism 4 includes a first limiting seat 41 and a fixing plate 43. The first limiting seat 41 is fixedly connected to the upper rear end of the limiting frame 3 and is located in the middle of the rear end of the limiting frame 3. The fixing plate 43 is fixedly connected to the lower rear end of the limiting frame 3. A collar is provided in the middle of the fixing plate 43. A first threaded rod 42 is rotatably installed in the collar and the first limiting seat 41. A first servo motor 46 is fixedly installed at the upper end of the first limiting seat 41. The first threaded rod 42 is fixedly connected to the output end of the first servo motor 46. A lifting movable bar 44 is threaded on the outer side of the first threaded rod 42. A first T-shaped block is fixedly installed on both sides of the front end of the lifting movable bar 44. The first T-shaped block is movably locked in the second slide groove 32 and the shape of the first T-shaped block is adapted to the second slide groove 32. A scissor-type lifting rod 45 is rotatably installed at the front end of the fixing plate 43 and the lifting movable bar 44, and the fixing plate 43 and the lifting movable bar 44 are located at the upper and lower rear ends of the scissor-type lifting rod 45.

[0036] Multiple cultivation limiting mechanisms 5 each include a rectangular frame 51. The rectangular frame 51 is installed at the front end of the connection of the scissor lift rod 45, and the connecting shaft of the scissor lift rod 45 is rotatably connected to the rectangular frame 51. Multiple rectangular frames 51 are arranged in a longitudinal array at the front end of the limiting frame 3. Multiple rectangular limiting grooves 511 are arranged in a transverse array inside the rectangular frame 51. Fixed shafts 52 are fixedly installed on the upper ends of both sides of the rectangular limiting grooves 511. Cultivation seats 53 are rotatably installed inside the fixed shafts 52. Counterweights 531 are fixedly installed at the lower end of the cultivation seats 53. Second T-shaped blocks 512 are fixedly installed on both sides of the rear end of the rectangular frame 51. The second T-shaped blocks 512 are movably locked in the first sliding groove 31. The shape of the second T-shaped blocks 512 is adapted to the shape of the first sliding groove 31.

[0037] The support mechanism 6 includes two second limit seats 61. The second limit seats 61 are fixedly connected to the upper rear part of the turntable 2 and the two second limit seats 61 are arranged longitudinally. A second threaded rod 62 is rotatably installed inside the second limit seat 61. A second servo motor 63 is fixedly installed on the upper rear part of the rear end of the second limit seat 61. The output end of the second servo motor 63 is fixedly connected to the second threaded rod 62. A threaded block 64 is threadedly installed on the outer side of the second threaded rod 62. A support connecting rod 65 is rotatably connected to the upper end of the threaded block 64. The end of the support connecting rod 65 away from the threaded block 64 is rotatably connected to the lifting movable bar 44.

[0038] A solar panel 7 is fixedly installed on the upper end of the limiting frame 3, and a storage battery 8 is fixedly installed on the upper right side of the limiting frame 3. The storage battery 8 is electrically connected to the solar panel 7, the first servo motor 46, the second servo motor 63 and the third servo motor.

[0039] In this embodiment, as Figures 1-4As shown, before the plant cultivation rack operates, the solar panel 7 at the upper end of the limiting frame 3 absorbs external light energy and converts it into electrical energy, which is stored in the battery 8 at the upper right end of the limiting frame 3. The battery 8 provides stable power to the first servo motor 46, the second servo motor 63, and the third servo motor. During operation, if the direction of light received by the plant needs to be adjusted, the third servo motor starts, driving the turntable 2 to rotate on the upper end of the base 1, thereby driving the limiting frame 3, the longitudinal spacing adjustment mechanism 4, the cultivation limiting mechanism 5, and the support mechanism 6 on the turntable 2 to rotate as a whole. When the height of the cultivation layer needs to be adjusted, the first servo motor 46 starts, and its output end drives the first threaded rod 42 to rotate within the collar of the first limiting seat 41 and the fixing plate 43. Since the lifting movable bar 44 is threadedly connected to the first threaded rod 42, and the first T-shaped blocks on both sides of the front end of the lifting movable bar 44 are movably locked in the second slide groove 32 at the rear end of the limiting frame 3, the rotation of the first threaded rod 42 drives the lifting movable bar 44 to move longitudinally along the second slide groove 32. When the moving bar 44 moves, it drives the scissor lift 45 to extend and retract. The rectangular frame 51 at the front end of the scissor lift 45 moves back and forth accordingly. At the same time, the second T-shaped blocks 512 on both sides of the rear end of the rectangular frame 51 slide longitudinally along the first sliding groove 31 at the front end of the limiting frame 3, realizing the longitudinal spacing adjustment of multiple cultivation limiting mechanisms 5. The cultivation seat 53 inside the rectangular frame 51 is rotatably connected through the fixed shaft 52, and the counterweight block 531 at the lower end always keeps it horizontal, preventing the cultivation substrate from tilting and spilling. During the movement of the moving bar 44, the second servo motor 63 starts synchronously. Its output end drives the second threaded rod 62 to rotate in the two longitudinally arranged second limiting seats 61. The threaded block 64 moves along the second threaded rod 62, thereby driving the support connecting rod 65 to rotate, forming a stable support for the moving bar 44. When the height of the moving bar 44 is higher and it stops moving, the second threaded rod 62 continues to rotate, driving the threaded block 64 to move backward, causing the upper end of the limiting frame 3 to tilt backward, improving the stability of the cultivation rack.

[0040] The working principle of this utility model is as follows: When the plant cultivation rack is working, the solar panel 7 at the upper end of the limiting frame 3 first absorbs light energy and converts it into electrical energy, which is stored in the battery 8 at the upper right end of the limiting frame 3. The battery 8 provides power support for the first servo motor 46, the second servo motor 63, and the third servo motor at the bottom of the base 1. When it is necessary to adjust the direction of light received by the plant, the third servo motor starts, and its output end drives the turntable 2 fixedly connected to it to rotate at the upper end of the base 1. The turntable 2 synchronously drives the limiting frame 3 installed at the upper end to rotate, as well as the longitudinal spacing adjustment on the limiting frame 3. The section mechanism 4, multiple cultivation limiting mechanisms 5, and support mechanism 6 rotate as a whole to ensure that the plants on the multiple cultivation limiting mechanisms 5 receive light evenly. When it is necessary to adjust the cultivation layer height according to the plant growth stage or variety, the first servo motor 46 starts, driving the first threaded rod 42 to rotate within the collar of the first limiting seat 41 and the fixing plate 43. Since the lifting movable bar 44 is threadedly connected to the first threaded rod 42, and the first T-shaped blocks on both sides of its front end are locked in the second slide groove 32 at the rear end of the limiting frame 3, the rotation of the first threaded rod 42 drives the lifting movable bar 44 to move longitudinally along the second slide groove 32. As the lifting rod 44 moves, it drives the scissor lift 45 to extend and retract. The rectangular frame 51 at the front end of the scissor lift 45 moves back and forth accordingly. At the same time, the second T-shaped blocks 512 on both sides of the rear end of the rectangular frame 51 slide longitudinally along the first sliding groove 31 at the front end of the limiting frame 3, realizing the longitudinal spacing adjustment of multiple cultivation limiting mechanisms 5 arranged in a longitudinal array. The cultivation seat 53 inside the rectangular frame 51 is rotatably connected through the fixed shaft 52, and works with the counterweight block 531 at the lower end to always keep it horizontal, preventing the cultivation substrate from tilting and spilling. During the movement of the lifting rod 44... The second servo motor 63 starts synchronously, driving the second threaded rod 62 to rotate within the two longitudinally arranged second limit seats 61, causing the threaded block 64 to move along the second threaded rod 62. The threaded block 64 drives the support connecting rod 65 to rotate, forming a stable support for the lifting movable bar 44. At the same time, when the height of the lifting movable bar 44 increases and it stops moving, the second threaded rod 62 continues to rotate, driving the threaded block 64 to move backward, causing the upper end of the limit frame 3 to tilt backward, improving the stability of the cultivation rack; ultimately achieving the functions of flexible adjustment of the cultivation rack layer height, uniform light exposure for plants, and stable structural support.

[0041] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
