Description

Technical Field

[0001] This utility model relates to a seedling rack, and more particularly to a seedling rack for agricultural breeding. Background Technology

[0002] Agriculture is an industry that utilizes the growth and development patterns of plants and animals to obtain products through artificial cultivation. Agriculture belongs to the primary sector and is a fundamental industry supporting national economic construction and development. The object of agricultural labor is living plants, and the product obtained is the plant itself. Crop breeding, also known as variety improvement, aims for high yield, stable yield, high quality, and high efficiency.

[0003] Chinese patent CN218125753U discloses a breeding rack for agricultural breeding. This utility model, through a diversion pipe, water supply pipe, nozzle, water supply structure, timer, and control panel, facilitates timely and quantitative watering of seedlings without the need for operators. It can provide sufficient water for seedlings and improve their growth.

[0004] The above-mentioned patent also presents the following problems during use: The above-mentioned patent places the breeding box inside the limiting box, and the limiting box is fixedly connected to the support frame, so the distance between the two limiting boxes is fixed and the distance between the two breeding boxes cannot be adjusted. In addition, in order to meet the need for more space after the seeds grow, the breeding frame is generally large in size, which makes it inconvenient for staff to operate the seedling box located above when placing ungerminated seeds in the early stage of seedling cultivation. Utility Model Content

[0005] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that the distance between the seed boxes in the existing seedling rack is fixed and cannot be adjusted. Moreover, the seedling rack is generally large, making it inconvenient for staff to operate the seedling boxes located on the top, thus making it inconvenient for staff to place ungerminated seeds in the early stage of seedling cultivation.

[0006] To address the aforementioned problems, this utility model provides a seedling rack for agricultural breeding, comprising a base plate. Two mirror-symmetrically distributed adjustment components are fixedly connected to the upper end of the base plate. Each adjustment component includes a fixed box, a motor fixedly connected to the inner cavity of the fixed box, and a screw fixedly connected to the upper end of the motor. The upper end of the screw movably passes through the fixed box. A multi-stage telescopic assembly is slidably connected to the upper end of the multi-stage telescopic assembly, and an adjustment plate is slidably connected to the upper end of each of the two adjustment plates. A top plate is fixedly connected to the upper ends of both multi-stage telescopic assemblies. Multiple mounting plates are fixedly connected between the two multi-stage telescopic assemblies. The multi-stage telescopic assembly includes eight mirror-symmetrically distributed... The sliders are arranged such that the upper ends of the four upper sliders are slidably connected to the lower ends of the corresponding adjustment plates, and the lower ends of the four lower sliders are slidably connected to the upper ends of the fixed box. Multiple scissor-type telescopic frames are hinged together among the eight sliders. Each of the multiple scissor-type telescopic frames is hinged with a directional rod at both ends. Each scissor-type telescopic frame includes a hinge rod. Fork rod 1 and fork rod 2 are respectively rotatably sleeved at both ends of the hinge rod. A lifting block is fixedly connected to the end of the hinge rod away from the mounting plate. The lifting block is threaded onto the outer surface of the screw rod. Both ends of the mounting plate are fixedly connected to the adjacent hinge rods. Incubation boxes are provided in the middle of the upper ends of both the base plate and the mounting plate.

[0007] In the above-mentioned seedling racks used for agricultural breeding, the initial spacing between multiple cultivation boxes is small and the height of the seedling rack is low, which not only facilitates storage but also makes it convenient for staff to place ungerminated seeds in the early stages of seedling cultivation. As the seedlings grow, the multi-stage telescopic components can be extended upwards by driving screws and lifting blocks to adjust the spacing between multiple cultivation boxes, making the growth of seedlings less obstructed and thus effectively improving the practicality of the seedling rack.

[0008] As a further improvement of this application, the upper end of the fixed box is chiseled with four grooves corresponding to the four sliders respectively. Two sliders are fixedly connected inside the fixed box. Two limiting blocks are slidably sleeved on the outer surface of the sliders. The upper end of the limiting block moves through the adjacent groove and is fixedly connected to the lower end of the slider.

[0009] As a further improvement of this application, telescopic rods are fixedly connected to the four upper corners of the base plate and the mounting plate. The upper ends of the uppermost telescopic rods are fixedly connected to the lower ends of the top plate, and the upper ends of the other telescopic rods are fixedly connected to the lower ends of the adjacent mounting plates.

[0010] As a further improvement of this application, a water storage pipe is fixedly connected to the lower end of both the top plate and the mounting plate. Multiple irrigation pipes are fixedly connected to the lower end of the water storage pipe, and an L-shaped water inlet pipe is fixedly connected to the right end of the water storage pipe.

[0011] As another improvement of this application, the water storage pipe is located directly above the incubation box, the lower end of the lowest incubation box is fixedly connected to the upper end of the base plate, and the lower ends of the other incubation boxes are fixedly connected to the upper end of the mounting plate.

[0012] As another improvement of this application, the front ends of both the base plate and the mounting plate are chiseled with placement grooves, and a support strip is slidably connected in the placement groove. The upper end of the support strip is fixedly connected to the lower end of the adjacent incubation box, and a handle is fixedly connected to the front end of the incubation box.

[0013] In summary, in practical applications, the small initial spacing between multiple cultivation boxes and the low height of the seedling rack not only facilitate storage but also make it convenient for staff to place seeds in the cultivation boxes and observe them during seed growth. As the seedlings grow, the multi-stage telescopic components can be extended upwards via screws and lifting blocks to adjust the spacing between multiple cultivation boxes, ensuring that seedling growth is not easily hindered, thereby effectively improving the practicality of the seedling rack.

Cultivation box. Detailed Implementation

[0023] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0024] First implementation method:

[0025] Figure 1 and Figure 2 The following is illustrated: A seedling rack for agricultural breeding includes a base plate 1. Two mirror-distributed adjustment components are fixedly connected to the upper end of the base plate 1. Each adjustment component includes a fixed box 2. A multi-stage telescopic component is slidably connected to the upper end of the fixed box 2. An adjustment plate 5 is slidably connected to the upper end of the multi-stage telescopic component. A top plate 6 is fixedly connected to the upper ends of the two adjustment plates 5. Multiple mounting plates 7 are fixedly connected between the two multi-stage telescopic components. Telescopic rods 15 are fixedly connected to the four corners of the upper end of the base plate 1 and the mounting plates 7. The upper ends of the multiple uppermost telescopic rods 15 are fixedly connected to the lower ends of the top plate 6, and the upper ends of the other multiple telescopic rods 15 are fixedly connected to the lower ends of the adjacent mounting plates 7. The telescopic rods 15 do not require electric drive and can extend and retract as the mounting plates 7 move up and down, thereby supporting and fixing the multiple mounting plates 7.

[0026] Figure 1 , Figure 3 , Figure 4 and Figure 5As shown: A motor 3 is fixedly connected to the inner cavity of the fixed box 2. Those skilled in the art can select a suitable model of motor 3 according to actual needs, such as Y2-63M1-2-0.18KW. A screw 4 is fixedly connected to the upper end of the motor 3. The motor 3 can drive the screw 4 to rotate, causing the lifting block 11 to move upward. The upper end of the screw 4 moves through the fixed box 2. The multi-stage telescopic assembly includes eight sliders 8 distributed in a mirror symmetrical manner. The upper ends of the four upper sliders 8 are slidably connected to the lower ends of the corresponding adjusting plates 5. The lower ends of the four sliders 8 located below are slidably connected to the upper end of the fixed box 2. The movement of the sliders 8 facilitates the vertical extension and retraction of the fork rod 1 902 and fork rod 2 903. Multiple scissor-type telescopic frames 9 are hinged together among the eight sliders 8. Each of the multiple scissor-type telescopic frames 9 is hinged with a directional rod 10 at both ends. The scissor-type telescopic frame 9 includes a hinge rod 901. Fork rod 1 902 and fork rod 2 903 are respectively rotatably sleeved at both ends of the hinge rod 901. A lifting block 1 is fixedly connected to the end of the hinge rod 901 away from the mounting plate 7. 1. The lifting block 11 is threaded onto the outer surface of the screw 4. By starting the motor 3, the screw 4 is rotated, causing the lifting block 11 to move up and down, thereby driving the lowermost hinge rod 901 to move upward. This causes the lowermost fork rod 1 902 and fork rod 2 903 to open and close in a scissor-like manner around the hinge rod 901. The movement is transmitted by the directional rod 10, which in turn drives each scissor-type telescopic frame 9 in the multi-stage telescopic assembly to extend and retract synchronously. The number of scissor-type telescopic frames 9 is not less than two, thereby enabling the equidistant adjustment of the spacing between multiple mounting plates 7, which is convenient for the operator. The upper end of the fixed box 2 is chiseled with four grooves 12, which correspond to the four sliders 8 respectively. Two sliding rods 13 are fixedly connected inside the fixed box 2. Two limiting blocks 14 are slidably sleeved on the outer surface of the sliding rods 13. The upper end of the limiting block 14 moves through the adjacent groove 12 and is fixedly connected to the lower end of the slider 8. The sliding rods 13 and the limiting blocks 14 can limit the multiple sliders 8 below, thereby effectively improving the stability of the multi-stage telescopic assembly when it extends.

[0027] Figure 2 and Figure 6 As shown: The two ends of the mounting plate 7 are fixedly connected to the adjacent hinge rods 901 respectively. The upper middle part of the base plate 1 and the mounting plate 7 are provided with a cultivation box 19. The lower end of the top plate 6 and the mounting plate 7 are fixedly connected to a water storage pipe 16. The lower end of the water storage pipe 16 is fixedly connected to multiple irrigation pipes 17. The right end of the water storage pipe 16 is fixedly connected to an L-shaped water inlet pipe. The water storage pipe 16 is located directly above the cultivation box 19. The lower end of the cultivation box 19 located at the bottom is fixedly connected to the upper end of the base plate 1. The lower ends of the other cultivation boxes 19 are fixedly connected to the upper end of the mounting plate 7. An external water pump is connected to multiple water inlet pipes through a hose. When it is necessary to irrigate the seedlings, water can be delivered to the water storage pipe 16 and then sprayed into the cultivation box 19 through the irrigation pipes 17, thereby effectively improving the practicality of this seedling rack.

[0028] When in use, the initial spacing between the multiple cultivation boxes 19 is small, and the overall height of the seedling rack is low. When not in use, the seedling rack is small in size and easy to store. When in use, the low mounting plate 7 makes it convenient for staff to place seeds in the cultivation boxes 19, and facilitates observation and recording during seed growth. As the seedlings grow, the motor 3 can be started to drive the screw 4 to rotate, causing the lifting block 11 to move upward, driving the multi-stage telescopic component to extend upward, adjusting the spacing between the multiple cultivation boxes 19, so that the growth of seedlings is not easily hindered, thereby effectively improving the practicality of the seedling rack.

[0029] Second implementation method:

[0030] This embodiment adds a support strip 18 to the first embodiment, while the rest remains the same as the first embodiment.

[0031] Figure 7 As shown: both the base plate 1 and the mounting plate 7 have placement grooves at their front ends. A support bar 18 is slidably connected in the placement groove. The upper end of the support bar 18 is fixedly connected to the lower end of the adjacent incubation box 19. A handle is fixedly connected to the front end of the incubation box 19.

[0032] When placing seeds into the seedling tray 19 or removing seedlings, the seedling tray 19 can be moved outward by pulling the handle outward, making it easier for staff to operate and thus effectively improving the convenience of this seedling rack.

[0033] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
