The Qu Tu mechanism includes removing native bracket, remove native roller and removing native column；It is described that native column is gone to go soil vertical including first Column and second removes native column, and described that native bracket is gone to go native bracket and second to remove native bracket including first, described first removes native column It is connected to first and removes native bracket, described second, which goes native column to be connected to second, removes native bracket, and described first removes native bracket and described Second goes native bracket to be symmetrical arranged by center line of gripping conveyor structure central axes；It is described to go native roller to be connected to described to go native branch Frame；

Described goes native column to be fixedly connected on conveying frame, so that a whole set of Qu Tu mechanism be made to be suspended under gripping conveyor structure Side；Described goes native roller surface to be covered with the protrusion being arranged regularly, and goes native bracket that native leg surface is being gone to can move up and down, Go native bracket in the relative position gone on native column by adjusting, it is adjustable to go to native roller and shallot root in the vertical direction Relative distance.

7. the self-propelled green Chinese onion combine harvester of duplicate rows as described in claim 1, which is characterized in that the laying mechanism includes Bearing block, laying rack, deposit belt, initiative roll shaft and driven roll shaft, the active roll connect dynamical system and by dynamical systems System driving, the deposit belt are around in active roller bearing and driven roller bearing, and the active roll and driven roller are set to laying rack Top, the laying rack are fixedly connected with preposition transverse onveyer, so that a whole set of laying mechanism be made to be set to above transport establishment.

8. the self-propelled green Chinese onion combine harvester of duplicate rows as described in claim 1, which is characterized in that the transport establishment includes Preposition transverse onveyer, traveling bed and postposition transverse onveyer, are driven by dynamical system；The transport establishment is set to Chassis main frame, the preposition transverse onveyer are located at the end bottom side of the gripping conveyor structure, lie against chassis main frame；It is described Traveling bed is located at the end bottom side of preposition lateral transfer tape feeding direction, is fixedly connected on chassis main frame, and the longitudinal direction Conveying belt inclined arrangement；The postposition transverse onveyer is located at the end bottom side of longitudinally fed tape feeding direction, and quantitatively beats Tie mechanism connection.

9. the self-propelled green Chinese onion combine harvester of duplicate rows as claimed in claim 8, which is characterized in that the quantitative binding mechanism Including quantitative rack, connecting rod and baffle；The connecting rod first end is fixedly connected with baffle, connecting rod second end and transmission shaft Hingedly, and connecting rod is embedded in quantitative machine frame inside, guarantees that baffle can be moved in a straight line in vertical direction；

The baffle and the move distance of postposition transverse onveyer in the vertical direction is 1-15cm.

10. a kind of self-propelled green Chinese onion combine harvest method of duplicate rows as claimed in any one of claims 1 to 9 wherein, which is characterized in that Include the following steps,

Starting；

Digging mechanism protrudes into soil layer and excavates shallot, and gripping conveyor structure changes tilt angle and height above ground, the shallot warp dug out It is transported by gripping conveyor structure to Qu Tu mechanism；

Qu Tu mechanism removes the soil of shallot root during clamping conveying；

Transport carries out bundling to a certain number of shallots to quantitative binding mechanism.
