Huge food production was a very big problem in Chinas bulk grain storage work. Improve the mechanization of Chinas grain storage efficiency is imminent. Chinas granary after decades of construction and development has gradually and international standards, in order to better meet the needs of modern granary, we need to design to improve efficiency of the bulk grain warehousing machinery and equipment. This article will focus on bulk grain warehousing slewing mechanism design calculations and stress analysis. The bulk grain warehousing machine is discussed in this article use requirements designed to meet the northern China warehouse, the corresponding data is based on warehouse. The boom system for the design of bulk grain warehousing machine slewing mechanism with a turntable, cloth bag systems, pumping systems constitute the main part of the bulk grain warehousing. In this paper, the design of the rotating mechanism from the rotary bearing, rotary pinion, speed reducer, hydraulic motors and other components constitute the rotary mechanism and stable performance, can bear a greater load, no noise at work. When Rotation mechanism at work, first of all, through the hydraulic oil to drive the hydraulic motor to rotate. Rotary coupling with reducer pinion slewing bearing outer ring gear meshing driven by rotation of the rotary table in order to achieve the rotation of the bulk grain warehousing boom conveyor system. In this paper, the corresponding formula to calculate the parameters of the various parts of the rotating mechanism, but also the various
