The benefits of using this form are: the two sides of the telescopic frame 130 rotate towards the middle at the same time, so that the leaves on the two sides can be beaten towards the middle and downwards, the beaten leaves can fall on the ground more intensively, and the better collection is facilitated.

In order to realize the rotation direction of the leaf peeling roller 133 in fig. 12a and 12b, the driving mechanism 140 needs to have two output shafts with opposite rotation directions, and as shown in fig. 13 and 14, the power output structure of the driving mechanism 140 of the present invention is as follows: the driving mechanism 140 is provided with an input shaft 143, a first output shaft 141 and a second output shaft 142, the first output shaft 141 and the second output shaft 142 are coaxially arranged and are respectively installed at the lower rotating shafts of the two lower swing arms 145-2, and the first output shaft 141 and the second output shaft 142 are respectively used for driving the rotating shafts of the two sets of telescopic frames 130 and the leaf peeling roller 133 to rotate.

The working process of the invention is as follows:

1) first, the chassis 110 is connected to the tractor 1.

2) After the transverse width and the longitudinal height of the telescopic frame 130 are adjusted according to the growth condition of the sugarcane in the field, pins or screws are inserted into the height adjusting holes 121-3 and the width adjusting holes 122-3 so as to keep the adjusted telescopic frame 130 at the current posture.

3) The driving mechanism 140 is started, the two coaxial but opposite-rotating first output shafts 141 and second output shafts 142 of the driving mechanism 140 start to rotate, and the first output shafts 141 and the second output shafts 142 drive one of the common rotating shafts 131-2 of each set of the telescopic frames 130 to start to rotate through the belts/chains in the two sets of the link mechanisms 145 (i.e., the belts/chains in the upper swing arm 145-1 and the lower swing arm 145-2). The common rotating shaft 131-2 sequentially drives all the rotating shafts 131-1 of the main folding frames 131 to rotate through belts/chains in the main folding frames 131, and finally drives the leaf peeling rotating rollers 133 on the outer side to rotate, and the soft rope 134 rapidly rotates under the action of centrifugal force.

4) The tractor 1 drives the leaf peeling machine 100 to move in the sugarcane field, and the high-speed rotating soft rope 134 is used for beating the nonfunctional leaves from the sugarcane. Because the longitudinal height and the transverse width of the telescopic frame 130 on the chassis 110 are adjustable, the coverage range of the leaf peeling roller 133 is changed. On the one hand, the spacing distances between the sugarcane ridges are different, on the other hand, the height of the sugarcane is higher and higher along with the growth of the sugarcane, so that the height of the follow-up leaves to be removed is higher and higher, the width and the height of the telescopic frame 130 are adjusted (shown in a reference to fig. 9 a-11 b), the sugarcane leaf stripping requirements under various conditions can be met, the adjusting mode is simple, and the sugarcane leaf stripping device is suitable for being popularized and used on a large scale.
