Topping is to remove the top advantage, inhibit the growth of branches and leaves, promote flowering and fruiting and increase the yield of crops by cutting off the top of crops in the growth process of the crops. In the current agricultural production, various crops such as cotton, tobacco, castor-oil plant, stevia rebaudiana, sesame and the like need to be topped.

According to the knowledge, the current topping operation generally adopts manual operation, the crop top is removed manually, the labor intensity is high, the operation efficiency is low, the current agricultural production requirement cannot be met, the production problem to be solved urgently is solved, and topping mechanization is an important mode for solving the production problem.

The mechanical topping cutting device replaces a manual topping, so that the labor intensity problem is solved, and the efficiency problem is also solved. In the aspect of topping mechanization, a topping cutting device is a key, and some achievements have been achieved at present, for example, chinese patent with application number CN201320642157.5 discloses a cotton topping device which adopts a single cutter structure and cuts off the topping center by high-speed rotation. Chinese patent application No. CN201020163619.1 discloses a slant pressing self-elastic high precision cotton topping machine, which presses down the top end of cotton through a slant pressing plate to make it pass through the lower end of a cylindrical rotating stand, and a rib cutter on the cylindrical rotating stand is just suitable for cutting off the top end position, so as to cut off the top end.

The existing topping cutting device considers how to realize cutting, but during topping, side leaves (also nutritive leaves) around the top center of a crop are generally damaged to different degrees, and the yield of the topped crop is seriously reduced even. Therefore, the protection and damage inhibition of the side leaf in the topping process become an urgent problem to be solved.
