A rear soil-gathering plate (14) connected to the frame (1) is symmetrically located below the plastic film roller (15). A front soil-gathering plate (13) is located on the side of the frame (1) away from the rear soil-gathering plate (14). A gearbox (902) is installed on the inner side of the frame (1) directly below the seed box (11). Eccentric wheel (502) and eccentric wheel (503) are fixed from left to right at the ends of the two chain tooth structure groups (501) that are close to each other. A duckbill device (505) is installed through the side of the crossbeam (5) away from the eccentric wheel (502). The bottom end of the duckbill device (505) is connected to the duckbill (506). A feed box (602) is symmetrically arranged on one side of the frame (1). A tipping bucket transmission component (601) is movably connected inside the feed box (602). Tipping buckets (603) are installed at equal intervals on the outer side of the toothed belt. A ground irrigation belt wheel (3) is installed at the top of the frame (1) on the right side of the seed box (11).
2. The potato planter of claim 1, wherein: The rotary tillage teeth (8) are rotatably connected to the frame (1) via bearings. The gearbox (201) is used to drive the rotary tillage teeth (8) to rotate in order to loosen the soil. The input end on the left side of the gearbox (201) is connected to the drive shaft (2), and the output end at the rear end of the gearbox (201) is connected to the output shaft (202). The drive shaft (2) is used to transmit power to the gearbox (201).
3. The potato planter of claim 2, wherein: The soil-throwing wheel (701) is connected to the output shaft (202) by a chain tooth structure three (7). The output shaft (202) drives the soil-throwing wheel (701) to rotate at high speed through the chain tooth structure three (7). The chain tooth structure three (7) includes a large sprocket connected to the output shaft (202), a small sprocket connected to the soil-throwing wheel (701), and a chain wrapped around the outside of the large sprocket and the small sprocket.
4. The potato planter of claim 1, wherein: The mulch roller (15) is used to cover the mulch along the ridges, the rear soil-gathering plate (14) is used to gather the soil into ridges where the rotary tillage teeth (8) pass, and the front soil-gathering plate (13) is used to collect soil; the input end on the left side of the gearbox (902) is connected to the drive shaft (901), and the drive shaft (901) and the drive shaft (2) are connected by a chain tooth structure (9), which transmits power to the gearbox (902) through the drive shaft (901).
5. The potato planter of claim 1, wherein: A chain tooth structure assembly (501) is provided between the gearbox 2 (902) and the frame (1). The eccentric wheel 2 (503) and the eccentric wheel 1 (502) are staggered vertically. The gearbox 2 (902) transmits power to the eccentric wheel 1 (502) and the eccentric wheel 2 (503) through the chain tooth structure assembly (501). The ends of the two eccentric wheels 1 (502) that are close to each other are rotatably connected to a crossbeam (5). A connecting rod (504) is rotatably connected between the crossbeam (5) and the eccentric wheel 2 (503).
6. The potato planter of claim 5, wherein: The chain tooth structure group (501) includes chain tooth structure a, chain tooth structure b and chain tooth structure c, and chain tooth structure c is triangular in shape. Chain tooth structure a and chain tooth structure b are located to the left of chain tooth structure c, and the two chain tooth structures a are located outside the two chain tooth structures b.
7. The potato planter of claim 1, wherein: The tipping bucket transmission component (601) includes a gear plate rotatably connected to both ends of the discharge box (602), a tipping bucket transmission shaft connected to the gear plate at the bottom end, and a toothed belt installed on the outside of the gear plate. The tipping bucket transmission component (601) is used to drive the tipping bucket (603) to move so as to send potato chunks into the discharge box (602) from above. A second chain tooth structure (6) is connected between the tipping bucket transmission shaft and the chain tooth structure group (501), and the second chain tooth structure (6) includes a gear plate group and a sprocket group.
8. The potato planter of claim 1, wherein: The top of the frame (1) is provided with a ground irrigation tape guide (301) between the seed box (11) and the ground irrigation tape wheel (3), and the ground irrigation tape guide (301) is used to send the ground irrigation tape to the front of the mulch film roller (15).
