[0016] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0017] Examples, such as Figure 1 and Figure 2 As shown, a potato planting device includes a frame 1, a soil covering mechanism 2, a seed metering component 3, a furrowing component 4, a drive component 5, and a fertilizer dispensing component 6. The soil covering mechanism 2 is located at the rear end of the frame 1, the seed metering component 3 is located at the upper middle part of the frame 1, the furrowing component 4 is located at the front bottom of the frame 1, a power component 8 is located on the rear side of the seed metering component 3, a handrail 9 is located at the rear end of the frame 1, and a control component 10 is located on the handrail 9. like Figure 3 and Figure 5 As shown, the seed metering assembly 3 includes a seed box 31 and a seed metering device 32. The seed box 31 is located at the upper end of the frame 1. The seed metering device 32 is a spoon-type seed metering device, located on the front side of the seed box 31. A rotating shaft 52 is provided at the lower end of the seed metering device 32. The rotating shaft 52 is horizontally placed and passes through the lower end of the seed metering device 32. A fertilizer box 61 is located on one side of the seed box 31. The other end of the rotating shaft 52 passes through the fertilizer box 61 and is fitted with an outer grooved wheel 62 around its periphery. The outer grooved wheel 62 is located at the bottom inside the fertilizer box 61. The fertilizer metering assembly 6 includes a fertilizer box. The lower ends of fertilizer box 61 and seed box 31 are all connected to a confluence box 7. The lower end of the confluence box 7 is open. When the rotating shaft 52 rotates, the seed metering device 32 scoops up potato seed tubers, and the outer grooved wheel 62 discharges fertilizer at the same time. The two flow into the seed furrow formed by the furrow opener 41 after converging through the confluence box 7, so that sowing and fertilization can be carried out simultaneously, reducing the number of operation steps. The seed metering device 32 adjusts the seed discharge rate through the rotation speed of the rotating shaft 52, and the outer grooved wheel 62 controls the fertilizer amount through the grooved wheel structure. The two work together to ensure a stable seed-fertilizer ratio. like Figure 4 As shown, the drive assembly 5 includes anti-slip wheels 51 and a rotating shaft 52. Two anti-slip wheels 51 are provided and connected to the left and right ends of the rotating shaft 52. The seed metering device 32 is driven by the rotating shaft 52. The outer grooved wheel 62 is located on the periphery of the rotating shaft 52 and rotates together with the rotating shaft 52. The anti-slip wheels 51 are in contact with the ground. The rotating shaft 52 converts the traction force into rotational power, driving the seed metering device 32 and the outer grooved wheel 62 to rotate.

[0018] The anti-slip wheel 51 has multiple anti-slip baffles 53 on its periphery. Each adjacent anti-slip baffle 53 has a mounting groove 57 between it. A rubber block 54 is placed inside the mounting groove 57, and the rubber block 54 slides within the mounting groove 57. An annular groove 58 is formed on the outer side of the anti-slip wheel 51, and a limiting ring 55 is placed inside the annular groove 58. The limiting ring 55 rotatably engages with the annular groove 58. The mounting groove 57 communicates with the annular groove 58. One end of each rubber block 54 is attached to the limiting ring 55. A turntable 56 is connected to the outside of 55. The limiting ring 55 is ratchet-shaped. When the limiting ring 55 is rotated, two adjacent rubber blocks 54 can be retracted into the mounting groove 57. The rubber blocks 54 are linked with the limiting ring 55 to realize bidirectional adjustment of the extension and retraction of the rubber blocks 54. On sticky and wet soil, the anti-slip baffle 53 is used to enhance the grip. When the soil sticks to the driving wheel, the turntable 56 is rotated to make the rubber blocks 54 move back and forth in the mounting groove to clean the soil.

[0019] The trenching assembly 4 includes a trencher 41, a connecting rod 42, a retaining sleeve 43, and a fixing knob 44. The retaining sleeve 43 is connected to the front end of the frame 1. One end of the connecting rod 42 is vertically inserted into the retaining sleeve 43, and the connecting rod 42 and the retaining sleeve 43 are slidably engaged. The other end of the connecting rod 42 is fixedly connected to the trencher 41. The fixing knob 44 is located on the retaining sleeve 43 and is used to limit the height of the trencher 41. The trencher 41 and the confluence box 7 are on the same straight line. The height of the trencher 41 is adjusted by sliding the connecting rod 42. After the fixing knob 44 is locked, the trenching depth is consistent, ensuring that the seed trenches are of uniform size. The trencher 41 and the confluence box 7 are on the same straight line, ensuring that the seed fertilizer falls accurately into the trench and avoiding deviation.

[0020] The soil covering mechanism 2 includes a fixed rod 21 and a soil covering plate 22. There are two fixed rods 21, and the upper ends of the two fixed rods 21 are respectively connected to the left and right sides of the rear end of the frame 1. There are two soil covering plates 22, which are respectively rotatably connected to the lower ends of two connecting rods 42. The two soil covering plates 22 form an angle that gradually decreases from front to back. The V-shaped angle allows the soil covering plate 22 to gather the soil on both sides towards the middle when it moves forward, covering the seed furrow and lightly compacting it to prevent the seeds from being exposed or losing moisture, thereby improving the germination rate. The rotatably connected soil covering plate 22 adapts to the undulating terrain and avoids soil covering failure due to soil sticking.

[0021] The power unit 8 includes a battery 81 and a rotating motor 82. A placement box is provided on the rear side of the seed box 31, and the battery 81 is placed in the placement box. The rotating motor 82 is located below the battery 81 and is electrically connected to the battery 81. The output shaft of the rotating motor 82 is connected to the rotating shaft 52 through a sprocket and chain mechanism. The motor replaces manual driving, has a stable speed, and the uniformity of seeding / fertilizing is better than manual operation. The control component 10 adjusts the motor speed (and thus controls the travel speed and discharge volume). The rechargeable design of the battery 81 reduces the cost of use and is suitable for small-scale farmland operations. All control components 10 are electrically connected to the battery 81, and the battery 81 is a rechargeable lithium battery.

[0022] Instructions for use: Loosen the fixing knob 44 on the sleeve 43, slide the connecting rod 42 to adjust the height of the furrow opener 41, lock the fixing knob 44, and ensure that the furrow opener 41 and the confluence box 7 are in a straight line to avoid the seeds and fertilizers from falling off-center, and ensure that the soil covers the furrow evenly to avoid the seeds being exposed. On rainy days, when the soil is wet and sticky: Rotate the turntable 56, and push the rubber block 54 to the opening of the mounting groove 57 through the ratchet-shaped limiting ring 55, so that the rubber block 54 moves back and forth to clean the mud on the anti-slip wheel 51, and drive through the anti-slip baffle 53 to avoid slipping; The control unit 10 on the handlebar 9 starts the rotating motor 82, the battery 81 drives the sprocket and chain mechanism to drive the rotating shaft 52 to rotate, the handlebar 9 controls the equipment to move forward at a constant speed, the anti-slip wheel 51 drives the seed and fertilizer discharge through the rotating shaft 52, and the soil covering plate 22 automatically covers the soil to the ditch as the equipment moves.
