In recent years, demand for ginger and the scale of its cultivation have continued to expand. Currently, most ginger cultivation methods involve machines loosening the soil, digging holes, manually placing several pieces of cut ginger seeds in the holes, and then covering them with compost. While some automated equipment has emerged, it fails to address issues such as the need for manual pre-cutting of seeds, uneven planting, and manual fertilization.

[0048] The working principle of the ginger planting machine is as follows:

[0049] Each time the frame 4 advances a preset distance, the loosening shovel cooperates with the loosener to open a V-shaped groove. Ginger cakes are manually put into the feed barrel (ginger needs to be manually trimmed into a cake shape in advance), and the driving motor 6 drives the central shaft 132 and the ginger sweeping impeller to rotate. The ginger sweeping impeller sweeps the ginger cakes from the discharge port of the feed barrel into the feeding device 2, and transports them along the pipe 21 of the feeding device 2 to the current limiting feeding mechanism; the current limiting feeding mechanism outputs the ginger cakes one by one to the raw material cutting mechanism 3; in the raw material cutting mechanism 3, the chain transmission mechanism is driven by the servo motor 1, and drives the belt transmission mechanism and the fixed shaft housing 373 of the material fixed shaft to rotate; the ginger cakes that fall on the material cutting mechanism are transported by the belt transmission mechanism to between the material fixed shaft and the hob shaft 36 with a polygonal cross section; the fixed shaft housing 373 of the material fixed shaft drives each spike 371 to rotate, and when the spike 371 rotates with the fixed shaft housing 373, the fixed shaft housing 373 of the material fixed shaft drives each spike 371 to rotate. When the fixed shaft housing 373 rotates to the output end of the belt drive mechanism and tilts upward, the spike 371 contacts the push section of the cam 374, sliding outward along the corresponding radial groove of the material fixed housing 373 and piercing the gingerbread sandwiched between the fixed shaft housing 373 and the cutter shaft. Simultaneously, the cutter blades on the cutter shaft cut the gingerbread, and the cut ginger pieces continue to be transported forward along the fixed shaft housing 373 and spike 371. When the spike 371 rotates with the fixed shaft housing 373 to face away from the belt drive mechanism, the spike 371 contacts the return section of the cam 374 and, under the restoring force of the return spring 372, slides inward along the corresponding radial groove of the material fixed housing 373, pushing the cut ginger pieces down to the seed screening mechanism. The spike 371 piercing the gingerbread assists the squeezing action of the fixed shaft housing 373 and the cutter shaft 36, further dragging the gingerbread and ensuring smooth cutting. In the seed screening mechanism, the perforated conveyor belt 1501 transports the cut ginger pieces to the seed convergence and flow limiting device 14, and the lighter debris in the cut ginger pieces falls from the sieve holes of the perforated conveyor belt 1501 into the debris recovery bucket 8, and then falls into the processing mechanism 71 of the debris processing device 7. The processing mechanism 71 further crushes the debris through the screw and transports it to the fertilizer storage bucket 92 of the solid fertilizer sprayer 9 through the slide 73; wherein, the air pump supplies air to the top circular tube with air holes 1503 and the bottom circular tube with air holes 1506, so that the top circular tube with air holes 1503 and the bottom circular tube with air holes 1506 spray air, which assists in blowing the debris from the sieve holes of the perforated conveyor belt 1501 into the debris recovery bucket 8.In the converging and current limiting device 14, the converging conveyor belt 1403 of the converging and conveying mechanism conveys the ginger pieces to the seed concentrating device 13. The ginger pieces on the converging conveyor belt 1403 fall one by one into the seed collecting cup of the seed concentrating device 13 under the guidance of the two current limiting plates 1404. When the weight sensor below the seed collecting cup detects a mass change of 15 to 25 g, the converging conveyor belt stops working. When the seed collecting cup is driven by the collecting cup transmission mechanism and supported by the collecting cup support mechanism and moves to the top of the sowing cylinder, it tilts and pours the ginger pieces into the sowing cylinder. The ginger pieces fall from the sowing cylinder into the V-shaped groove opened by the tiller. When another seed collecting cup moves to the output end of the converging conveyor belt 1403, the converging conveyor belt restarts working and continues to convey the collected ginger pieces to the seed concentrating device 13. After the ginger pieces fall from the seeding barrel into the V-shaped groove opened by the tiller, as the frame 4 continues to move forward, when the solid fertilizer sprayer 9 advances to the V-shaped groove position, the spraying impeller 93, driven by the drive motor 5, mixes the solid fertilizer in the fertilizer storage barrel 92 with the debris and sprays it into the V-shaped groove where the ginger pieces have been planted; then, the covering mechanism advances to the V-shaped groove position, and the two spiral blades of the covering mechanism, driven by the drive motor 3, roll the soil on both sides and the rear of the V-shaped groove into the V-shaped groove, completing the covering.

[0050] The process of using a ripper and a ripper to create a V-shaped groove is as follows:

[0051] like Figure 1 and Figure 2 As shown, the driving motor 3 drives the loosening shaft and each loosening knife to rotate, and each loosening knife pushes the soil into the loosening shovel 10 (of course, when there is a lot of soil accumulated in the loosening shovel 10, it will slide out to both sides), thereby opening a V-shaped groove.

[0052] The process of the current-limiting feeding mechanism outputting gingerbreads one by one to the raw material cutting mechanism 3 is as follows:

[0053] like Figure 5 He Ru Figure 7 As shown, when there are no gingerbreads on the bottom plate 223, it is in a high position and the baffle 251 is in a horizontal state. When a piece of gingerbread slides onto the bottom plate 223, the weight of the gingerbread causes the bottom plate 223 to move downward, which drives the connecting rod 222 to extend the planar spiral spring 221, and the baffle 251 swings down to block the remaining gingerbread in the pipe 21. When the bottom plate 223 drops to the lowest point, the ratchet 23 is higher than the groove 224. As the rotating shaft and each ratchet 23 rotate under the drive of the feed motor 24, the gingerbread can be pushed from the bottom plate 223 to the raw material cutting mechanism 3. After the gingerbread on the bottom plate 223 slides to the raw material cutting mechanism 3, the spiral spring 221 retracts, driving the bottom plate 223 to rise through the connecting rod 222, and the baffle 251 swings up to no longer block the gingerbread in the pipe 21.
