[0031] Working principle: When working, first add a proper amount of soil to the storage bin 011 of the soil processing equipment 01, and the soil slides down to the rear end of the storage bin 011 through the slope surface, and then the soil is transported to the guide trough 0131 through the lifting component 013. The soil in the guide trough 0131 falls into the planting box 5 through the scraping mechanism 014. At this time, first start one of the longitudinal scraping plates 0146 or the transverse scraping plates 0147. After the scraping plates are scraped and reset, start the other scraping plate to achieve secondary scraping, and then start the conveyor belt 2 to transport the planting box 5 to the sowing equipment 02; When the planting box 5 passes through the rolling roller 024, the soil is compacted, and when it passes through the sowing roller 025, the sowing roller 025 takes the seeds from the seed storage box 026 and places them in the breeding tray 027 to complete the sowing; the seed taking method of the sowing roller 025 is pneumatic seed taking, and seed particles are accumulated at the seed outlet 0262 of the seed storage box 026. The sowing roller 025 rotates under the action of the driving motor 2 0257, and the partition plate 0254 is stationary and divides the inner cavity of the sowing roller 025 into two left and right chambers. The negative pressure pipe interface 02515 is connected to a negative pressure pipe, and the negative pressure pipe keeps the right chamber in the sowing roller 025 in a negative pressure state for a long time. When the sowing roller 025 rotates clockwise, the T-shaped seed suction strip 02503 also rotates accordingly, and each T-shaped seed suction strip 02503 passes through the seed outlet 02 62, the negative pressure in the cavity causes the seeds to be sucked into the conical through holes on the T-shaped seed suction strip 02503. When each T-shaped seed suction strip 02503 rotates to the lowermost end of the sowing roller 025, it enters the left chamber. Since the air pressure in the left chamber is equal to the external atmospheric pressure, the seeds in the conical through holes on the T-shaped seed suction strip 02503 will lose the suction generated by the negative pressure, and thus fall into the planting box 5 moving at a uniform speed. Each of the above T-shaped seed suction strips 503 completes the above steps successively, and finally completes the sowing work of the planting box 5. The conveyor belt 2 then transports the planting box 5 to the soil covering equipment 03. The soil storage box 031 is filled with soil, which is transported to the soil crushing box 033 by the screw feeder 032. After the soil is crushed, it falls into the planting box 5 to cover the seeds with soil; and then is transported to the soil compacting equipment 06 by the conveyor belt 2; After the soil is compacted by the soil roller 061, the watering device 063 waters the soil. The water storage box 065 stores water. The water storage box 065 is provided with a water pump, which sprinkles the water onto the planting box 5 through the watering hole 0633. After the seeds are watered, they are transported to the cutting device 04 to cut the grass carpet. When the planting box 5 is transported to the bottom of the tool magazine rack 043, the cylinder 043213 acts on the cutting assembly 0433 on the bottom sliding guide rail 04321, so that the cutting knife 043315 on the cutting assembly 0433 cuts downward and cuts the grass carpet in the planting box 5 into uniform small pieces of grass carpet. When the cutting knife 043315 needs to be replaced, the cutting assembly 0433 on the bottom sliding guide rail 04321 is pushed to disengage the clamping auxiliary part 043317 from the clamping block 043214 until the cutting assembly 0433 is pushed onto the transposition guide rail 0443. Then, the driving motor three 04451 is started. When the driving motor three 04451 drives the transposition guide rail 0443 to rise to the horizontal position of the middle and lower sliding guide rails 04322, the cutting assembly 0433 is moved to the bottom sliding guide rail 04321. 3 is pushed onto the middle and lower sliding guide rails 04322, and then the driving motor three 04451 is restarted to raise the transposition guide rail 0443 to the corresponding sliding guide rail of the required tool assembly, and then the required tool assembly is pushed onto the transposition guide rail 0443. Under the action of the driving motor three 04451, the transposition guide rail 0443 is lowered to the position of the bottom sliding guide rail 04321, and finally the required tool assembly is pushed onto the bottom sliding guide rail 04321, and the clamping auxiliary part 043317 is elastically clamped with the clamping block 043214 to realize the connection between the cutting assembly 0433 and the cylinder 043213, and the tool changing work is completed, and then the cylinder 043213 is used to realize the cutting movement, and the conveyor belt 2 then transports the cut grass carpet to the destination for grass carpet maintenance and cultivation.
