This embodiment is through setting up the device 4 of digging, utilize sawtooth 423 cutting earth, utilize deflector 422 can with the silt and the holistic silt separation of promotion, utilize curved plate 421 of digging can further separate earth to set up the net of fretwork on the plate 421 of digging, and wash the lotus root of plate 421 top through setting up the scouring mechanism 43, make silt separated and follow net discharge, make the lotus root of digging cleaner, improve the quality of the lotus root of digging. Simultaneously, lotus roots on the digging plate 421 can be flushed into the conveying hopper 41 under the impact action of water sprayed by the flushing mechanism 43, so that the mutual collision and extrusion of the lotus roots are avoided, the damage to the lotus roots is reduced to the greatest extent, the quality of the lotus roots which are dug is improved, and the digging efficiency of the lotus roots is improved.
In this embodiment, by arranging the transportation device 3, the lotus roots picked by the picking device 4 are transported to the collection device 5, and the lotus roots falling from the conveying hopper 41 are received by the elastic filtering grating 36, so that damage caused by collision of the lotus roots is reduced, and impurities such as partial silt, sand and stone can be filtered, so that the purity of the transported lotus roots is improved. Meanwhile, through holes for filtering impurities are formed in the conveying belt 33, and a chain net structure is arranged on the surface of the conveying belt, so that the breakage rate of lotus roots in the conveying process is reduced. Two mounting panels 31 set up in the both sides of conveyer belt 33 to prevent that the lotus root in the conveying from falling down from conveyer belt 33, guarantee the smooth conveying of lotus root, and set up the square hole of screening lotus root on the mounting panel 31, can screen out the debris that mixes in the lotus root, and prevent that external hard thing from touching the lotus root of conveying and fish tail lotus root, improve the conveying efficiency of lotus root simultaneously.
In this embodiment, the collection device 5 is arranged to collect lotus roots transported from the transportation device 3, the collection bag 52 is provided with the leak holes 521, sundries such as silt and sand in the lotus roots are screened out again, the purity of the collected lotus roots is improved, and the collection efficiency is improved. 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.
