[0031] The working principle of the artificial mixed grassland fertilization device provided by the present invention is as follows: When in use, first start the hydraulic cylinder 203 to move the output shaft of the hydraulic cylinder 203 upward or downward, the output shaft of the hydraulic cylinder 203 drives the connecting block 204 to move upward or downward, the connecting block 204 drives the hinged rod 205 to move, and the connecting rod 205 drives the vertical plate 206 to slide on the corresponding through hole 210 and the sliding rod 211, so that the distance between the two corresponding moving wheels 208 can be adjusted. When the distance between the two corresponding moving wheels 208 can be moved in the sowing gap between the two grasses, the hydraulic cylinder 203 is closed, and then the four moving motors 209 are started to rotate the four moving wheels 208 to realize the movement of the entire device on the grass; When it is necessary to fertilize the lawn, first determine whether the type of fertilizer to be applied to the lawn is solid granular fertilizer or liquid fertilizer. When the fertilizer to be applied is solid granular fertilizer, first add the fixed granular fertilizer into the hopper 303, then start the air pump 304, and the air pump 304 evacuates air to the square tube 307 through the connecting tube 305, so that negative pressure is generated in the square tube 307. When the pressure difference between the air pressure in the square tube 307 and the atmospheric pressure becomes larger and larger, the thrust of the atmospheric pressure on the push rod 308 becomes larger and larger. When the thrust of atmospheric pressure is greater than the elastic force of spring 309, spring 309 is compressed, push rod 308 moves into square tube 307, push rod 308 drives connecting plate 310 to move, connecting plate 310 drives cutting plate 312 to slide, so that receiving plate 312 is gradually moved out of discharge cone tube 302, and solid granular fertilizer in hopper 303 falls into the grass from the bottom of discharge cone tube 302, so that solid granular fertilizer is sprayed on the grass during the whole moving process of the device; When the fertilizer to be applied is liquid fertilizer, the second valve 406 is opened at this time, and the liquid fertilizer is added into the material storage box 401 by establishing the actuation 407, and then the second valve 406 is closed. At this time, it is only necessary to start the submersible pump when the entire device is moving. The submersible pump will spray the liquid fertilizer through the first discharge pipe 402, the second discharge pipe 403 and a valve 404, and finally from the liquid fertilizer nozzle 405, thereby realizing the work of spraying liquid fertilizer on the lawn.
