Because the collecting bag 52 is arranged at the rear ends of the mounting plate 31 and the conveyor belt 33, lotus roots fall from the bag mouth of the collecting bag 52, the lotus roots are prevented from being piled up at the bag mouth of the collecting bag 52, the lotus roots are conveniently collected, meanwhile, the collecting bag 52 is made of flexible materials, collision of the lotus roots can be reduced, and damage to the appearance of the lotus roots is reduced. The retaining ring 53 is fixed on the collecting bag 52 and is buckled on the mounting plate 31, so that the collecting bag 52 is convenient to mount and dismount when lotus roots are collected fully, the harvesting efficiency is improved, and the harvesting personnel can operate conveniently.

In this embodiment, the transmission device 2 is arranged to drive the excavating device 4, the transporting device 3 and the collecting device 5 to coaxially rotate relative to the power device 1, so that the inclination angles of the excavating device 4, the transporting device 3 and the collecting device 5 can be conveniently adjusted, and the harvesting machine can be suitable for different scenes. When the lotus roots are in a deeper area, the lifting mechanism 22 pushes the supporting frame 21 to rotate, so that the digging device 4 is submerged to a required depth, and lotus root digging is performed; when the lotus roots are in a shallower area, the picking and digging device 4 can be lifted to the required depth by the lifting mechanism 22 for picking and digging the lotus roots; when the lotus roots do not need to be picked, the lifting mechanism 22 pushes the supporting frame 21 to rotate so that the picking device 4, the conveying device 3 and the collecting device 5 are horizontal, and therefore the picking device 4, the conveying device 3 and the collecting device 5 are prevented from colliding with the ground, and the combined lotus root harvesting machine is convenient to move on the ground. Meanwhile, the driving mechanism drives the bucket 42 to rotate, so that the bucket 42 can pick lotus roots at different angles, the picking area of the picking device 4 is increased, and the picking efficiency of the lotus roots is improved.

The novel technical scheme is not limited to the scheme; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
