A clamping rod 25 is fixedly arranged on the outer side of the second hydraulic cylinder 26. The clamping rod 25 is slidably connected to the L-shaped frame 8. Driven by the extension and contraction of the second hydraulic cylinder 26, the L-shaped frame 8 can be lifted up and down, thereby the plurality of pattern knives 13 can dice the large potatoes at the koji bin 31.

[0025] Fixed seats 18 are respectively provided on both sides of the rear end of the frame 1, and movable rods are provided on the inner sides of the two fixed seats 18. The fixed seats 18 and the movable rod can install the roller 16 to the rear end of the frame 1, and the roller 16 is installed at the end of the movable rod away from the fixed seat 18. A clamping sleeve 17 is fixedly provided on the outer side of the movable rod, and covering plates 15 are fixedly provided on the edges of both sides of the clamping sleeve 17. The clamping sleeve 17 is convenient for installing the covering plate 15 on the outside of the movable rod, and then after turning over the soil, the excess soil can be covered back, and the covering plate 15 can be made of rubber sheet and used. Pin sleeves are provided on the outer sides of both ends of the rotating shaft 12, and a connecting seat 14 is rotatably sleeved on the outer side of the pin sleeve. A first hydraulic cylinder 11 is provided on the end of the connecting seat 14 away from the rotating shaft 12, and the outer side of the first hydraulic cylinder 11 is installed on the outer side of the top frame 2 through a fixed baffle 10. Under the connection of the pin sleeve, the telescopic drive of the first hydraulic cylinder 11 can prompt the rotating shaft 12 to be able to fine-tune the rotation, so as to cooperate with the later use.

[0026] It should be noted that during the dicing process of the multi-piece flower knife 13, the block is larger than the slice, so the consumption of potatoes is within the normal range and does not affect the planting, and all of them are inside the soil.

[0027] Working principle: when in use, the frame 1 can be connected to the agricultural machinery, and then the processing and sowing are carried out under the traction of the agricultural machinery. The potatoes can be quickly distributed through the support platform 6 and the inclined multiple support rods 7. The small potatoes directly fall into the sliding platform 24 through the gap between the two adjacent support rods 7, while the larger potatoes directly slide into the inner part of the silo 31 because of the support rods 7. Then the second hydraulic cylinder 26 drives the L-shaped frame 8 to move downward, causing the multiple flower knives 13 at the lower end of the L-shaped frame 8 to move downward to cut the larger potatoes and then rise again. The third hydraulic cylinder 30 drives the connecting rod 40 to extend into the inner box 28, causing the rotating drum 42 and the multiple clamping columns and the absorbent cotton 44 to suck the ash in the ash box 4 by the ash pump 34 and push it into the silo 31. The gears 41 at both ends of the rotating drum 42 are meshed with the racks 27 at the corresponding positions of the silo 31 during the movement, causing the rotating drum 42 to rotate. During the re-storage process, not only can the wood ash be fully adhered to the cut potatoes, but the cut potatoes can also be turned over, so that the cut potatoes can quickly fall into the inner side of the slide table 24 through the rectangular drop opening on the inner surface of the qu bin 31. The inclined surfaces at both ends of the slide table 24 can accelerate the rolling of the potatoes into the hard shell. Driven by the rotation of the motor 46, the disc 35, and the connecting rod 37, the ring bar 45 will rotate, and the rubber scraper 36 will be driven to rotate at a uniform speed to guide the small potatoes and the cut potatoes on the inner surface of the slide table 24 toward the inside of the plastic tube 23. The processed potatoes can be transported to the inside of the seeding wheel 9 through the connecting tube 20. The inclined shovel pipe 19 connected to the inside of the seeding wheel 9 rolls into the soil with the traction of the agricultural machinery, and the corresponding potato pieces inside also fall into the soil from there. Then, after the agricultural machinery moves, the covering plate 15 at the rear end of the frame 1 covers the soil.

[0028] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention.
