In the harvesting process, the method specifically operates as follows:

when the crawler belt walking device 2 walks or turns, after an operator starts the engine 11, the operator controls the relevant operating rods on the operating platform 7, controls the crawler belt walking control rod 702 to control the walking of the crawler belt walking device 2, controls the walking speed of the crawler belt walking device 2 by the gear shifting control rod 704, and controls the turning of the crawler belt walking device 2 by the left-right shifting of the comprehensive operating rod 701;

lifting control of the primary conveying device 4, an operator controls a relevant operating rod on the operating platform 7, and controls the comprehensive operating rod 701 to toggle back and forth for controlling the lifting of the primary conveying device 4, and the excavating device 3 is installed at the front end of the primary conveying device 4 and follows the lifting of the primary conveying device 4 through telescopic control of hydraulic cylinders 15 on two sides of the primary conveying device 4;

the whole machine is controlled in a linkage way, a clutch control rod 705 is controlled to control the operation of a primary conveying device 4 and a secondary conveying device 5, the clutch control rod 705 drives a poke rod 711 to push a rotating wheel 712 against a transmission belt connected with an engine 11 and an input end of a reduction gearbox 12 through a connecting rod 706, a connecting sheet 707, a transmission rod 708, a connecting plate 709 and a tension spring 710, so that the transmission belt is tensioned, the transmission belt connected with the engine 11 and the input end of the reduction gearbox 12 before the engine is in a loose state, the engine 11 does not drive the reduction gearbox 12 to operate, after the transmission belt is tensioned, the reduction box 12 firstly drives the secondary conveying device 5 to operate, the secondary conveying device 5 respectively drives the primary conveying device 4 to operate and the auxiliary seedling separator 9 to operate, then the primary conveying device 4 is linked with a transmission wheel 308 of the digging device 3 to drive the transmission wheel 308 to rotate, the transmission wheel 308 drives a transmission shaft 307 to rotate, and the transmission shaft 307 drives a seedling distributor 305 to rotate through a T-shaped converter 306.

The present invention and its embodiments have been described above, and the description is not intended to be limiting, and the drawings are only one embodiment of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should appreciate that they can readily use the disclosed conception and specific embodiments as a basis for designing or modifying other structures for carrying out the same purposes of the present invention without departing from the spirit and scope of the invention as defined by the appended claims.
