[0016] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0017] like Figures 1-4 As shown, a small rice transplanter suitable for hilly areas includes a rice transplanter body, a transplanting needle unit installed on the rice transplanter body, and a control host. The main body of the rice transplanter is existing technology well known to those skilled in the art. For example, Chinese Patent No. CN218277796U discloses a transplanting depth adjustment device for a rice transplanter, which discloses a main body of the rice transplanter. The main body of the rice transplanter is not the key improvement part of this technical solution, so the main body of the rice transplanter will not be described in detail, and it is not drawn in detail in the accompanying drawings of the specification.

[0018] The core of this technical solution lies in the improvement of the rice transplanting needle unit, specifically as follows: Figures 1-4 As shown, the rice transplanter needle unit includes an upper body 1 of the rice transplanter needle installed on the main body of the rice transplanter. The lower end of the upper body 1 of the rice transplanter needle is fixedly connected to two side needles 3 arranged in parallel. A seedling needle groove 2 is formed between the two side needles 3. A telescopic adjustment mechanism is installed on the upper body 1 of the rice transplanter needle. A C-shaped frame 5 located inside the seedling needle groove 2 is installed on the telescopic adjustment mechanism. The C-shaped frame 5 can slide inside the seedling needle groove 2 along the axis of the rice transplanter needle unit. A rotating shaft 6 is rotatably connected inside the C-shaped frame 5. An electric locking component adapted to the rotating shaft 6 is fixedly connected to the C-shaped frame 5. The electric locking component is electrically connected to the control host and is used to lock the rotating shaft 6 during rice transplanting.

[0019] At this time, the rotating shaft 6 can be moved inside the seedling groove 2 by the telescopic adjustment mechanism to change the planting depth; When the seedling slides into the seedling needle groove 2 through the seedling box, the electric locking device releases the lock on the rotating shaft 6. When the seedling and the rotating shaft 6 come into contact, the rotation of the rotating shaft 6 can reduce frictional damage to the seedling. When the seedling is inserted, the electric locking device locks the rotating shaft 6 to reduce the phenomenon of the thrust pushing the rotating shaft 6 to rotate during the transplanting process, thereby reducing the phenomenon of changes in the transplanting depth caused by changes in the contact position between the rotating shaft 6 and the seedling.

[0020] Among them, a rubber protective layer can be fixedly connected to the outer side of the rotating shaft 6 to further reduce friction damage to the seedlings.

[0021] like Figures 1-2 As shown, the telescopic adjustment mechanism includes a screw 8 rotatably connected inside the upper body 1 of the rice transplanter needle. A threaded sleeve 9 is threadedly connected to the outside of the screw 8. The threaded sleeve 9 is slidably connected inside the upper body 1 of the rice transplanter needle. One end of the threaded sleeve 9 is fixedly connected to the C-shaped frame 5. By rotating the screw 8, the threaded sleeve 9 can be moved to adjust the position of the C-shaped frame 5.

[0022] Meanwhile, a servo motor 7 can be fixedly connected to the upper end of the main body 1 of the transplanting needle. The output end of the servo motor 7 is connected to the screw 8 for transmission. The servo motor 7 is electrically connected to the control host. The servo motor 7 can be automatically controlled during the transplanting process by the control strategy stored in the control host to complete the movement of the C-shaped frame 5 and the rotating shaft 6. The control strategy can include manual trigger adjustment or automatic adjustment according to the field slope sensor data to adapt to the frequent fine-tuning needs of hilly fields.

[0023] like Figures 2-4 As shown, a pivot rod 11 is fixedly connected to the pivot on both sides of the rotating shaft 6. The pivot rod 11 is rotatably connected to the C-shaped frame 5. The electric locking component includes a side shell 10 fixedly connected to the outside of the C-shaped frame 5. One end of the pivot rod 11 extends into the side shell 10 and is fixedly connected to a first friction plate 13. An electromagnet 15 and a return spring 16 are fixedly connected inside the side shell 10. One end of the return spring 16 is fixedly connected to a second friction plate 14. Anti-slip textures are provided on the opposite sides of the first friction plate 13 and the second friction plate 14 to enhance the friction between the first friction plate 13 and the second friction plate 14. To ensure locking stability, the second friction plate 14 is slidably connected inside the side shell 10. The second friction plate 14 is provided with a magnetic material similar to iron. The electromagnet 15 is electrically connected to the control host. By activating the electromagnet 15, the second friction plate 14 is pulled, causing the second friction plate 14 to separate from the first friction plate 13, thus unlocking the rotating shaft 6. When the electromagnet 15 is de-energized, the return spring 16 pushes the second friction plate 14, causing the second friction plate 14 to contact the first friction plate 13, thus locking the first friction plate 13, thereby locking the rotating shaft 6.

[0024] Meanwhile, a limiting sleeve 17 is fixedly connected to the end face inside the side shell 10. A limiting rod 12 is slidably connected inside the limiting sleeve 17. One end of the limiting rod 12 is fixedly connected to the second friction plate 14. The setting of the limiting rod 12 and the limiting sleeve 17 can reduce the force rotation displacement of the second friction plate 14.

[0025] Among them, the two side needle bodies 3 are provided with limiting grooves 4 on opposite sides, the C-shaped frame 5 is slidably connected inside the limiting grooves 4, and the side shell 10 is located inside the limiting grooves 4 to improve the sliding stability of the C-shaped frame 5.

[0026] The working principle of this utility model is as follows: Move the rice transplanter to the hilly paddy field operation area, place the seedlings evenly in the seed box of the main body of the rice transplanter, start the control host, and ensure that the servo motor 7 and electric locking parts are in the initial state, and the rotating shaft 6 can rotate freely. Based on the current soil thickness and slope of the field, the host computer inputs the insertion depth parameter or manually triggers the adjustment command to drive the servo motor 7 to operate. The servo motor 7 drives the screw 8 to rotate. The screw 8 and the threaded sleeve 9 are connected by threads, which drives the threaded sleeve 9 to slide along the inside of the upper body 1 of the transplanting needle, thereby pushing the C-shaped frame 5 to move up and down along the limiting groove 4 of the side needle body 3 until the rotating shaft 6 reaches the set height. The seedling feeding mechanism of the main body 1 of the rice transplanter transports the seedlings in the seedling box one by one into the seedling needle groove 2. The seedlings slide down the seedling needle groove 2 and contact the rotating shaft 6. At this time, the rotating shaft 6 maintains a free rotation state. The "rolling contact" replaces the traditional "sliding extrusion". With the outer rubber protective layer, the pressure on the seedling stem is dispersed to avoid wear and tear on the tender seedlings. At the same time, the attached soil and impurities can be shaken off during the rotation to prevent jamming. Once the seedlings are positioned to the set location by the rotating shaft 6, the control host synchronously sends a command to the electric locking component. The electromagnet 15 is de-energized, and the return spring 16 pushes the second friction plate 14, causing the second friction plate 14 to contact the first friction plate 13, locking the shaft rod 11, thereby fixing the rotating shaft 6 and preventing the rotating shaft 6 from shifting due to the force of the soil, thus ensuring accurate insertion depth. Cyclic operation: After the rice planting needle is pulled out of the soil, the electric locking part is unlocked again, the rotating shaft 6 resumes its rotation, and waits for the next seedling to be transported. The above steps are repeated to adapt to the operation needs of small plots and multiple turning points in hilly fields.

[0027] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
