NOVELTY - Vertical type biomass granulator main shaft comprises a cross shaft (10) where its upper central part is set with rectangular parallelepiped support bars (20). The cross shaft and rectangular parallelepiped support bar are molded by casting. The cross shaft lower end central part is provided with a circular groove (30), where its one side is provided with a rectangular convex strip (31). The circular groove is matched with the groove rotating shaft. The rectangular support bars is connected to rectangular groove (21). The rectangular groove is uniformly provided with multiple screw holes.    USE - Used as vertical type biomass granulator main shaft.    ADVANTAGE - The main shaft increases working efficiency, can increase the output value of biomass particle machine, has small volume, has simple structure, and is suitable for popularizing.    DETAILED DESCRIPTION - Vertical type biomass granulator main shaft comprises a cross shaft (10) where its upper central part is set with rectangular parallelepiped support bars (20). The cross shaft and rectangular parallelepiped support bar are molded by casting. The cross shaft lower end central part is provided with a circular groove (30), where its round one side is provided with a rectangular convex strip (31). The circular groove is matched with the groove rotating shaft. The rectangular support bars upper end is connected to central rectangular groove (21). The rectangular groove is uniformly provided with multiple screw holes. The rectangular groove is set with vertical rectangular plate provided with rectangular groove screw hole matching with groove and screw hole, and fixed vertically through fixing bolt with rectangular supporting bar and rectangular groove. The cuboid supporting bar at end of rectangular groove two end is provided with multiple thread holes. The rectangular support bar is set with the transverse rectangular plate. The transverse rectangular plate through fixing bolt is a rectangular supporting pole and fixed with screw thread hole. The distance between cross middle shaft and transverse board, and vertical rectangular plate has adjustable wheel.
