Description

Technical Field

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

[0002] Rice is a herbaceous species of the Oryza genus, and it is also the most important and oldest food crop in the Oryza genus. It originated in China, and rice has been cultivated in the Yangtze River basin of China for seven thousand years. According to the type of rice, rice can be divided into indica rice and japonica rice, early rice and mid-late rice, glutinous rice and non-glutinous rice, as well as other classifications. Rice is generally cultivated in paddy fields, and soilless cultivation is called water rice. Rice is generally not more than one meter tall, and those around two meters tall are newly cultivated giant rice.

[0003] Most rice seedling cultivation devices on the market currently involve placing vertical seedling racks inside greenhouses to grow rice seedlings. This effectively saves space within the greenhouse, thus reducing operating costs. The seedling racks have multiple planting boards connected from top to bottom via sliding grooves. The planting boards are secured within the racks with pins. Rice seedlings are planted inside the planting boards. When the height of the rice seedlings exceeds the spacing between the planting boards, the height of the planting boards needs to be adjusted to match the seedling height. To adjust, first, the pins are pulled out to release the constraint on the planting board. Then, the planting board is pulled out of the groove on the seedling rack, moved, and then slid into another set of grooves, thus adjusting the spacing between the upper and lower planting boards. Because adjustment requires not only vertical but also horizontal movement of the planting boards, it involves significant movement of the boards, making the operation rather cumbersome. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: A rice planting and cultivation device includes a frame. Two symmetrical sliding grooves are formed on the inner wall of the frame. Multiple limiting grooves are formed on both inner side walls of the frame. Multiple planting plates are slidably connected inside the frame. Slider blocks are fixedly connected to both ends of each planting plate. The sliders are located inside the sliding grooves and slidably connected to them. A fixing block is fixedly connected to the lower end of each planting plate. Two symmetrically arranged fixing sleeves are fixedly connected to the lower end of each planting plate. A movable plate is slidably connected through the fixing sleeve, with one end extending into the limiting groove.

A torsion spring is wound around the surface of the rotating rod, with one end fixedly connected to the fixing block and the other end fixedly connected to the rotating plate. Linkage plates are hinged to both ends of each rotating plate, with one end of the linkage plate hinged to the movable plate. A rectangular groove is formed at the lower end of each planting plate, and the rotating plate is aligned with the rectangular groove.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0016] Please see Figure 1-5 This utility model provides a technical solution: a rice planting and cultivation device, including a frame 1. Two symmetrical sliding grooves 2 are formed on the inner wall of the frame 1. Multiple limiting grooves 3 are formed on both inner side walls of the frame 1. Multiple planting plates 4 are slidably connected inside the frame 1. Slider blocks 5 are fixedly connected to both ends of each planting plate 4. The sliders 5 are located inside the sliding grooves 2 and slidably connected to them. A fixing block 6 is fixedly connected to the lower end of each planting plate 4. Two symmetrically arranged fixing sleeves 7 are fixedly connected to the lower end of each fixing sleeve 7. A movable plate 13 is slidably connected through the fixing sleeve 7. One end of the movable plate 13 extends into the interior of the limiting groove 3. A rotating rod 8 is rotatably connected inside the fixed block 6. A rotating block 9 is fixedly connected to one end of the rotating rod 8, and a rotating plate 10 is fixedly connected to the other end of the rotating rod 8. A torsion spring 11 is wound around the surface of the rotating rod 8. One end of the torsion spring 11 is fixedly connected to the fixed block 6, and the other end of the torsion spring 11 is fixedly connected to the rotating plate 10. Both ends of the rotating plate 10 are hinged with linkage plates 12. One end of the linkage plate 12 is hinged to the movable plate 13. A rectangular groove is opened at the lower end of the planting plate 4, and the rotating plate 10 is aligned with the rectangular groove.

[0017] In this embodiment, when it is necessary to adjust the distance between the two planting plates 4, firstly, one hand supports the lower surface of the planting plate 4, and then the other hand rotates the rotating block 9, thereby causing the rotating rod 8 to rotate, which in turn drives the rotating plate 10 to rotate. At the same time, the torsion spring 11 is twisted. As the rotating plate 10 rotates, it drives the two linkage plates 12 on both sides to perform planar movement, thereby causing the two movable plates 13 to slide inside the two fixed sleeves 7 respectively, performing a retracting movement. One end of the movable plate 13 disengages from the inside of the limiting groove 3, thereby releasing the locking of the planting plate 4. When it is necessary to move the planting plate 4 upward, the planting plate 4 is directly lifted by hand, causing the planting plate 4 to move upward. The slider 5 slides upward inside the sliding groove 2. After the movement is complete, the rotating block 9 is released, and under the torque of the torsion spring 11, the rotating plate 10 and the rotating rod 8 reverse. This causes the two linkage plates 12 to move and reset, which in turn drives the two movable plates 13 to expand, allowing one end of the movable plate 13 to re-insert into the other limiting groove 3, thus locking the moved plate. When it is necessary to move the planting plate 4 downward, after unlocking the planting plate 4, the user can directly use the gravity of the planting plate 4, combined with the support of the hand, to move the planting plate 4 downward. Therefore, through the cooperation of the rotating rod 8, torsion spring 11, rotating plate 10, and linkage plate 12, the user can directly rotate the rotating block 9 to make the two movable plates 13 disengage from the limiting groove 3, thereby unlocking the planting plate 4. Then, the user can directly move the planting plate 4 up and down to adjust the distance between the two planting plates 4. Finally, by releasing the rotating block 9, the position of the planting plate 4 can be locked. Therefore, the operation is convenient and improves the user's work efficiency.

[0018] Specifically, the end face of the frame 1 is provided with multiple positioning lines 14, which are aligned with the center line of the limiting groove 3. The lower end of the planting plate 4 is fixedly connected to an indicator plate 15, and the indicator head of the indicator plate 15 is aligned with the center line of the movable plate 13.

[0019] In this embodiment, when the planting plate 4 moves up and down, it causes the indicator plate 15 to move. When the indicator plate 15 is aligned with the positioning line 14, one end of the movable plate 13 is also aligned with the limiting groove 3. The user can observe whether the indicator plate 15 is aligned with the positioning line 14, which makes it easier for the user to align the movable plate 13 with the limiting groove 3.

[0020] Specifically, one end of the movable plate 13 is chamfered, and the end face of the limiting groove 3 is rounded.

[0021] In this embodiment, when the user releases the rotating block 9, since one end of the movable plate 13 has a chamfer and the end face of the limiting groove 3 has a rounded corner, even if there is a certain deviation between the alignment of the movable plate 13 and the limiting groove 3, the user only needs to release the rotating block 9 and slightly move the planting plate 4 to allow the movable plate 13 to enter the interior of the limiting groove 3.

[0022] Specifically, an L-shaped plate 17 is fixedly connected to the end face of the planting plate 4. A threaded rod 18 is threadedly connected to the surface of the L-shaped plate 17. A rotating disk 19 is fixedly connected to one end of the threaded rod 18. A rubber layer is provided on one end of the rotating disk 19. A rubber strip 16 is fixedly connected to the end face of the frame 1. The rotating disk 19 is aligned with the rubber strip 16.

[0023] In this embodiment, when the planting board 4 needs to be moved downwards, the threaded rod 18 is first rotated, which causes the rotating disk 19 to move and move closer to the rubber strip 16, so that the rotating disk 19 squeezes the rubber strip 16. Then, the rotating block 9 is rotated, and the weight of the planting board 4, combined with the supporting force of the hand on the planting board 4, causes the planting board 4 to move downwards. At the same time, the threaded rod 18 is moved downwards, causing the rotating disk 19 to slide on the surface of the rubber strip 16. The friction between the rotating disk 19 and the rubber strip 16 can produce a certain damping effect on the movement of the planting board 4, making it easier for the user to control the downward speed of the planting board 4 and preventing the problem of difficulty in controlling the speed when the planting board 4, which is filled with soil, is moving downwards due to its large weight.

[0024] Specifically, the fixed sleeve 7 is provided with several balls 20 inside, and the fixed sleeve 7 is tactilely connected to the movable plate 13 through the balls 20.

[0025] In this embodiment, the fixed sleeve 7 rolls relative to the movable plate 13 via the ball bearing 20. By setting the ball bearing 20, the friction between the fixed sleeve 7 and the movable plate 13 is reduced, making the movable plate 13 move more smoothly inside the fixed sleeve 7.

[0026] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
