More preferably, the inclination angle is greater than 60° and less than 90°. The leaf gathering device 1 is inclined towards the conveying device 2 of the white radish, which is more conducive to gathering and conveying the white radish leaves. At this inclination angle, through practice, it is proved that the white radish leaf gathering device can better complete the operations of gathering and conveying the white radish leaves.
[0028] In one embodiment, the tassel lifter 10 is fixed to the vertical support 40 by a connecting rod. The bottom of the tassel lifter 10 is horizontally arranged, and the top is inclined towards the leaf gathering claw belt 20, so that a sharp angle is formed between the bottom and the top to insert into the bottom of the tassel leaves on both sides of the white radish. Preferably, the side of the tassel lifter 10 is triangular in shape, and the forward driving force is used to lift the tassel leaves and combine with the belt leaf gathering claw 20 to gather the tassel leaves into a bundle.
[0029] In one embodiment, the leaf gathering claw assembly is fixed to the vertical support 40 and is located at the rear end of the tassel lifter 10. It includes a belt leaf gathering claw 20 and a driving mechanism for driving the movement of the belt leaf gathering claw 20. The driving mechanism is fixed to the support frame 42, and the driving mechanism drives the belt leaf gathering claw 20 to rotate cyclically from bottom to top in a vertical plane. Among them, the leaf gathering claw belt 20 is composed of a base belt and leaf gathering fingers 22. The working principle and structure of the base belt are the same as those of an ordinary belt. The leaf gathering fingers 22 are made of rubber and are evenly distributed at equal intervals on the outer edge of the base belt.
