Specifically, the second grabbing unit is hinged to the first mounting frame 210, and the second grabbing unit can swing back and forth between the fifth position and the sixth position. Specifically, when the second grabbing unit is in the fifth position, the grabbing assembly 200 is closed to grab the fruit vines, and when the second grabbing unit is in the sixth position, the grabbing assembly 200 is unfolded to release the fruit vines or to allow materials dropped from the first conveying assembly 100 to fall on the grabbing assembly 200 and be grabbed by the grabbing assembly 200.

[0046] Specifically, the second grabbing unit includes a second mounting frame 240, which is hinged to the first mounting frame 210, and the second mounting frame 240 can swing back and forth between the fifth position and the sixth position. The second mounting frame 240 is in transmission connection with the third driving device 270. A second grabbing rod 250 is fixedly mounted on the second mounting frame 240, and a plurality of second grabbing rods 250 are provided, and the plurality of second grabbing rods 250 are sequentially spaced along the length direction of the second mounting frame 240.

[0047] Each second grabbing rod 250 is provided with a second grabbing wheel assembly, which includes a plurality of second grabbing wheels 260 sleeved on the second grabbing rod 250 , and the plurality of second grabbing wheels 260 are sequentially spaced along the length direction of the second grabbing rod 250 .

Specifically, the third driving device 270 is one of an electric push rod, a cylinder or a hydraulic cylinder, and the first end of the third driving device 270 is hinged to the first mounting frame 210, and the second end is hinged to the second mounting frame 240.

[0049] The first driving device 300 is used to drive the first conveying assembly 100 to swing back and forth between the first position and the second position, and the first conveying assembly 100 is driven from the first position to the second position by the first driving device 300 to dump the fruit vines with fruits on the first conveying assembly 100 onto the grabbing assembly 200. Specifically, the first driving device 300 is one of an electric push rod, a cylinder or a hydraulic cylinder, and the first end of the first driving device 300 is hinged to the frame 700, and the second end is hinged to the first conveying assembly 100.

[0050] The second driving device 400 is used to drive the grabbing assembly 200 to reciprocate between the third position and the fourth position, and the grabbing assembly 200 is driven to swing back and forth between the third position and the fourth position by the second driving device 400 to separate the fruits from the fruit vines. Specifically, the second driving device 400 is one of an electric push rod, a cylinder or a hydraulic cylinder, and the first end of the second driving device 400 is hinged to the frame 700, and the second end is hinged to the first mounting frame 210.

[0051] A second conveying assembly 500 is disposed below the grabbing assembly 200. The width direction of the second conveying assembly 500 is inclined relative to the horizontal plane, that is, the first side of the second conveying assembly 500 is higher and the second side is lower. The second conveying assembly 500 is used to convey the fruit vines from which the fruits have been separated. A third conveying assembly 600 is disposed at the lower side of the second conveying assembly 500. The third conveying assembly 600 is used to convey the separated fruits.

[0052] Among them, when the fruit falls on the second conveying component 500, the fruit can roll along the second conveying component 500 to the third conveying component 600. When the fruit vines fall on the second conveying component 500, the fruit vines cannot fall along the second conveying component 500 to the third conveying component 600, so that the separated fruits are conveyed by the third conveying component 600, and the fruit vines with separated fruits are conveyed by the second conveying component 500.

[0053] During use, the separated fruits fall onto the second conveying assembly 500 under the action of gravity, and then roll along the second conveying assembly 500 to the third conveying assembly 600 to be conveyed by the third conveying assembly 600. When the fruit separation is completed, the grabbing assembly 200 moves to the releasing position and unfolds to release the fruit vines, which fall onto the second conveying assembly 500 under the action of gravity. After the fruit vines fall onto the second conveying assembly 500, they cannot continue to fall along the second conveying assembly 500 to the third conveying assembly 600, and therefore, the fruit vines are conveyed by the second conveying assembly 500.

[0054] On the other hand, the utility model also provides a harvester, comprising the separation mechanism described in any of the above embodiments.
