The battery pack 25 can convert direct current into alternating current for use by the entire device under the action of the inverter, thereby ensuring the normal operation of the device.

[0044] The use method and advantages of the present invention: The leek harvester which can be adjusted according to the terrain has the following working process:

[0045] like Figures 1 to 11As shown: the battery pack 25 supplies power to the entire device. When the first electric telescopic column 2 is extended or retracted, the support seat 3 and the carrying plate 1 move relative to each other, so that the height of the carrying plate 1 can be adjusted according to the height of the ridge platform. The driving roller 4 drives the device to move. After holding the handle 7, the walking direction of the device can be manually adjusted. The guide plate 16 guides the leek to between the two pulleys 13. The rotation of the rotating shaft 20 drives the first bevel gear 2402 to rotate, the second bevel gear 2403 and the sleeve 2404 rotate, the rotating plate 2407 and the cutting knife 2408 rotate, and the cutting knife 2408 automatically cuts the leek. At the same time, the rotation of the first circular gear 9 drives the first driving rod 10 to rotate, thereby driving the first conveyor belt 14 and the corresponding pulley 13 to rotate, and the second circular gear 11 rotates with the rotation of the first circular gear 9. The first conveyor belt 14 and the second conveyor belt 15 convey the cut leeks to the collecting frame 6. The water storage tank 17 stores water. The first pump wheel 2102 rotates to drive the second pump wheel 2103 to rotate. The first connecting pipe 2104 pumps the water in the pump box 2101 into the pump box 2101. The water is sprayed out through the second connecting pipe 2105, the first water delivery pipe 2106, the second water delivery pipe 2107 and the nozzle 2111 in sequence to moisten the hardened land. At the same time, the cam 23 rotates, and the cam 23 repeatedly squeezes the two movable blocks 2206. When the movable block 2206 is squeezed and moved, the corresponding second piston 2204 moves. When the movable block 2206 is not squeezed, the movable block 2206 and the second piston 2204 automatically pop open under the action of the second compression spring 2205, and the second piston 2204 moves back and forth. When the second piston 2204 moves outward, the third piston 2208 moves leftward, thereby pushing the fourth piston 2210 to move leftward. The first piston 2108 moves under the action of oil pressure. When the second piston 2204 rebounds, the first piston 2108 automatically rebounds under the action of the first compression spring 2110, and the first piston 2108 slides back and forth in the first oil groove 2109. The second water pipe 2107 swings back and forth to increase the spraying range. When the cutting knife 2408 is at the highest height, when the second piston 2204 moves outward, the fifth piston 22 11. The third oil cylinder 2212 and the sixth piston 2213 are not enough to push the seventh piston 2214 to move. Only the fourth piston 2210 presses oil into the first oil groove 2109. At this time, the amount of oil pressure is the least. Before using the cutting knife 2408, the second electric telescopic column 2405 extends to drive the movable plate 2406, the rotating plate 2407 and the cutting knife 2408 to move downward, so as to facilitate the adjustment of the height of the cutting knife 2408 according to the cutting depth of the leek. When the movable plate 2406 moves downward, the movable frame 2410 and the two eighth pistons 2414 move downward, and the sixth piston 2213 moves to the right. When the second piston 2204 moves outward, the fifth piston 2211, the third oil cylinder 2212 and the sixth piston 2213 push the seventh piston 2214 to move, so as to facilitate the increase of the amount of oil pressure.The swing amplitude of the second water delivery pipeline 2107 becomes larger, and the swing amplitude of the second water delivery pipeline 2107 can increase as the cutting depth increases.

[0046] In summary, the leek harvester that can be adjusted according to the terrain achieves the purposes of convenient disassembly and replacement, adjustment of cutting depth, water spraying for moistening, placement of water spraying, and increase of the spraying swing amplitude as the cutting depth increases, thus meeting people's usage needs.
