Therefore, the directional terms used are for illustrative purposes and not for limiting the creation of this utility model.

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] Example 1: An automatic chili seedling planting device, such as... Figures 1-5 As shown, it includes a load-bearing component, which includes a support frame 2. The support frame 2 is equipped with a planting structure, which includes a transport component and a soil-drilling component, such as... Figure 6 As shown, the soil-drilling assembly includes a horizontal lead screw I7, one end of which is connected to a stepper motor 15.

The transport assembly includes a support plate 3, with a rotating belt 13 on the support plate 3. A drive motor I22 is mounted on the support frame 2, connected to a transmission gear 5. The transmission gear 5 is securely fixed to the rotating shaft via a cylindrical pin or a conical pin. One end of the rotating shaft is rigidly connected to the drive motor I22 via a coupling. The transmission gear 5 is structurally connected to the rotating belt 13, which has several seedling cups 4. The support frame 2 has a soil-collecting structure. The support frame 2 of this device has a control circuit assembly and a power supply assembly in the middle, with the support plate 3 on top. The power supply assembly is located at the bottom of the control circuit assembly and includes three 4.5V power batteries and a 12V power battery, which respectively power the microcontroller and the motor. Figure 8 As shown, the right side of the battery has a charging port and a power indicator light, and the rear side of the battery has a power output switch control circuit including a main control chip, a motor driver, a geared motor drive module, and a Bluetooth module. The main control chip is an STM32 microcontroller, the stepper motor driver is a TB6600, the geared motor drive module is an L298N, and the Bluetooth module is an HC-05.

[0032] Example 2: An automatic chili seedling planting device, such as... Figure 6 As shown, a guide rod I8 is installed on the support frame 2 via a bearing seat I6. A seedling tube 18 and a drill bit seat 21 are slidably connected on the guide rod I8. The seedling tube 18 and the drill bit seat 21 are arranged in parallel. A drill motor 16 is provided on the drill bit seat 21. A drill bit 19 is connected to the output end of the drill motor 16.

[0033] The rotating belt 13 is rectangular in shape and includes a chain. A sprocket 14 is installed inside the rotating belt 13, and the rotating belt 13 and the sprocket 14 are tensioned together. The sprocket 14 is mounted on the support plate 3. The chain is connected by multiple chain link pins, and the sprocket 14 is meshed with the chain, with the teeth of the sprocket 14 precisely engaging with the rollers of the chain.

[0034] The support plate 3 is provided with a seedling dropping hole 24. The position above the seedling dropping hole 24 corresponds to the position of the seedling transport cup 4, and the position below the seedling dropping hole 24 corresponds to the position of the seedling dropping tube 18.

[0035] like Figure 7 As shown, the soil collection structure includes a soil collection support 26, on which a bevel gear assembly is provided. The bevel gear assembly includes a driving bevel gear 10 and a driven bevel gear 11. The driving bevel gear 10 is connected to the soil collection motor 25 and meshes with the driven bevel gear 11. The driven bevel gear 11 is connected to a lead screw assembly, which includes a transverse lead screw II 17, on which an elastic soil collection plate 20 is provided.

[0036] The number of driven bevel gears 11 is two, and the two driven bevel gears 11 are arranged opposite each other on both sides of the driving bevel gear 10.

[0037] The lead screw assembly also includes guide rod II 29, and guide rod II 29 and transverse lead screw II 17 are respectively mounted on the soil collection bracket 26 via bearing housing II 12. Bearing housing I 6 and bearing housing II 12 are of the vertical KP08 bearing housing and the diamond-shaped KLF08 bearing housing, respectively. Guide rod I 8 and guide rod II 29 are mounted on the support frame 2 via the vertical KP08 bearing housing; transverse lead screw I and transverse lead screw II 17 are mounted on the support frame 2 via the diamond-shaped KLF08 bearing housing.

[0038] The elastic soil collection plate 20 includes a mounting base 28, which is connected to a baffle 27 via a spring 23.

[0039] The support plate 3 is connected to the support frame 2 by four symmetrical columns 9.

[0040] Everything else is the same as in Example 1.

[0041] Once the automatic seedling planter reaches the designated planting position, the stepper motor 15 of the seedling guide device drives the transverse lead screw II to move the drill bit 19 to the designated position. The drill motor 16 drives the vertical lead screw, causing the drill bit 19 to move downwards and begin drilling. After drilling is completed, the drill motor 16 rotates in the opposite direction to lift the drill bit 19, and the stepper motor 15 rotates at a fixed number of revolutions, driving the transverse lead screw II to move the seedling drop tube 18 to the seedling drop hole 24. Simultaneously, the drive motor I 22 drives the transmission gear 5 to rotate, which in turn drives the rotating belt 13 to rotate the seedling cup 4, transporting the seedling to the designated position and placing it into the preset pit through the seedling drop tube 18. In addition, the walking motor of the walking device drives the traveling wheels, moving the soil collection structure to the seedling position. The soil collection device is controlled by the soil collection motor 25. The driven bevel gear 11 rotates in the opposite direction through the intersecting shaft, driving the elastic soil collection plate 20 to move inward. After the soil collection operation is completed, the soil collection motor 25 rotates in the opposite direction to return the soil collection plate to its position, thus completing a complete planting process.

[0042] Once the automatic planting machine reaches the designated planting position, the stepper motor 15 of the planting structure is driven by a fixed number of pulses output by the microcontroller to achieve a fixed rotation speed, which in turn causes the horizontal lead screw I7 to move the drill bit 19 within a set distance. During drilling, the drill bit 19 moves synchronously with the vertical lead screw, achieving the effect of drilling and moving downwards simultaneously. After drilling is completed, the drill bit 19 is retracted by the stepper motor 15 in the reverse direction, simultaneously completing the upward movement of the drill bit 19 and the loosening of the soil.

[0043] After drilling, the stepper motor of the planting structure moves according to a predetermined number of revolutions, positioning the seedling tube 18 directly below the hole. The drive motor I 22 in the transport assembly rotates periodically to ensure that the distance the seedling cup 4 moves each time is fixed. The soil-collecting motor 25 of the soil-collecting device is connected to the driven bevel gear 10 and the driven bevel gear 11, which is connected to the transverse lead screw II 17. The driven bevel gears 11 on both sides rotate in opposite directions using a cross shaft, thereby driving the elastic soil-collecting plate 20 to retract and return to its original position. The drive motor rotates at a fixed time to ensure that the seedlings are not pinched. The elastic soil-collecting plate 20 adopts a two-section connection structure and is equipped with a spring 23 assembly. It can automatically release and compress the spring 23 according to changes in terrain, thereby adjusting the height of the soil-collecting plate and improving its ground contact. After the soil-collecting plate is retracted, it can effectively fill the surrounding soil into the holes, thereby optimizing the planting environment for the seedlings and improving their survival rate.

[0044] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
