[0008] Preferably, the flexible clamping device includes a main frame hinged on the frame, and the main frame is provided with a plurality of conveying groups arranged along the longitudinal direction, and the conveying groups include two annular clamping conveying chains arranged along the longitudinal direction and conveying along the front-to-back direction, and a clamping channel for clamping the garlic stems is formed between the two clamping conveying chains in the same conveying group, and the clamping channel extends upward from front to back at an angle.

[0039] The main frame 38 is provided with a driven sprocket 24 and a driving sprocket for driving the clamping conveying chain 25 for transmission. The main frame 38 is also provided with a plurality of torsion springs 28 arranged along the bulb transmission direction and located on the inner side of the clamping conveying chain 25. The other end of the torsion spring 28 is fixedly connected to the bracket 26. The bracket 26 is axially connected to a floating sprocket 27 that cooperates with the clamping conveying chain 25. The main frame 38 is also provided with a support column 29 for supporting the torsion spring 28.

[0040] The straw supporting device 1 includes a rotating shaft 9 axially connected to a fixed frame 14, a plurality of fixed plates 8 axially arranged on the rotating shaft 9, a plurality of flexible straw strips 7 uniformly arranged along the circumference of the fixed plate 8, and a plurality of straw dividers 10 located behind the straw strips and arranged longitudinally are provided on the fixed frame 14, a walking channel for the bulbs to pass through is formed between two adjacent straw dividers 10, and the fixed frame 14 is fixedly connected to the main frame 38.

[0042] The main frame 38 is fixedly connected with a plurality of telescopic motors 15 arranged in the longitudinal direction, and a wheel frame is connected to the telescopic shaft extending downward from the telescopic motor 15, and a depth limiting wheel 11 that travels on the ground is connected to the upper shaft of the wheel frame. The height of the main frame 38 is adjusted by extending and retracting the telescopic motor 15, thereby achieving adjustment. The telescopic motor 15 and the depth limiting wheel 11 form an automatic depth limiting adjustment module 12.

[0043] A cam is connected to the power shaft of the vehicle frame 35, and the cam is coaxially arranged with the power shaft. A truss frame 20 extending forward is hinged on the cam, and the truss frame 20 is located on the side of the cam. The truss frame 20 is hinged on the cam through a connecting shaft. A plurality of digging shovels 16 arranged in the longitudinal direction are inserted and fixed on the truss frame 20. The main frame is also hinged with hydraulic rods 18 corresponding to the digging shovels 16 and located above the digging shovels 16, and the number of hydraulic rods is the same as the number of digging shovels, and one hydraulic rod is connected to one digging shovel. The top of the hydraulic rod is hinged on a fixed support 19, and the fixed support is bolted to the main frame. The protruding end of the hydraulic rod 18 is hinged on the digging shovel 16. The truss frame 20 is also provided with a depth sensor 17. The digging shovel 16, the truss frame 20, and the hydraulic rod 18 form an excavation device 2.

[0044] The beard cutting device 4 includes a cutting plate 21 located below the clamping channel, a cutting channel located directly below the clamping channel is opened on the cutting plate 21, and the cutting channel extends obliquely to the side.

The conveying group includes two annular clamping conveying chains 25 arranged longitudinally and conveyed in the front-to-back direction. A cutting channel for clamping the garlic stems is formed between the two clamping conveying chains 25 in the same conveying group. The cutting channel extends horizontally. Since the cutting board 21 restricts the bulbs from moving upward, the clamping conveyor belt located on the main frame 38 will continue to drive the garlic stems to move upward, so the garlic stems will be separated from the garlic stems. At this time, the arrangement of the conveying group on the cutting board 21 facilitates the continued clamping of the garlic stems.

[0046] The collecting device 6 includes a dust removal box 33 located behind the cutting plate 21, a collecting box 34 located directly below the discharge port of the dust removal box 33, and an upward transfer conveying mechanism 32 for driving the bulbs to be transported into the dust removal box 33.

[0049] When the utility model is in use, the power device on the frame 35 drives the frame 35 to move forward, the rotating shaft 9 drives the weeding bar to rotate, and at the same time the digging shovel 16 goes deep into the ground to dig the bulbs out of the soil, and then under the action of the weed divider 10, the fallen garlic plants are diverted and gathered upward to the clamping channel, and the garlic stems move upward and backward under the clamping of the clamping conveying chains 25 on both sides of the clamping channel, and the garlic stems move upward and obliquely following the clamping conveying channel. When the height of the cutting channel is reached, the garlic stems will be inserted into the corresponding cutting channel during the movement, that is, the bulbs will be below the cutting channel. As the garlic stems rise, the bulbs will be pushed to the bottom surface of the cutting plate 21, and the cutting plate 21 will limit the bulbs from continuing to move upward, so that the bulbs can be cut off from the cutting plate 21. The stem can only move backward following the transmission of the clamping conveyor chains 25, so that all the bulbs are pushed onto the cutting plate 21, so that the fibrous roots are located at the same height. As the bulbs continue to move backward, the fibrous roots are cut by the fibrous disc knife 22, and then the garlic stems are cut when passing through the stem cutting disc knife 23, so that the bulbs are separated from the garlic stems, and the bulbs fall onto the longitudinal transfer conveying mechanism 31 and are transported to the upward transfer conveying mechanism 32 by the longitudinal transfer conveying mechanism 31. Under the transportation of the upward transfer conveying mechanism 32, they arrive at the impurity removal box 33, and other impurities are removed and then fall into the collection box 34 for collection. When a certain amount is collected, quantitative unloading is achieved through the cooperation of the hydraulic rod 18 and the pressure sensor 37.
