The invention provides a stalk granulating set, comprising a crushing mechanism, a stock bin, a uniform speed feeding mechanism, a granulator, an automatic receiving mechanism and a dedusting cooling device sequentially in a stalk moving direction. By using stirring fins in the feeding device, it is possible to solve the problem that stalks easily arch to provide uniform feeding; by rotating a fixed disc at constant speed, it is possible to provide dynamic balancing between free-swinging blades and fixed blades; the fixed blades fixed on the periphery of a fixing disc can cut stalks when the fixing disc rotates; the free-swinging blades contact the surface of the fixing disc to form shearing force to cut the stalks. Presser rods are arranged above a feeding screw, a pressing rotary shaft drives the presser rods to press cyclically the crushed stalks keeping falling into the stock bin, and feeding efficiency can be improved. The bottom of a cooling bin is provided with a large-area air intake segment of meshed structure, thereby providing full cooling for stalk granules in the bin; the set is imparted high yield, reduced consumption and environmental friendliness through the full-automatic full-closed feeding, granulating, and storage and cooling.
