The paper comprises a mathematical model of technological process of dry material transporting by the screw conveyor. The mathematical model developed in the article, presents the movement of material particle of the dry medium in the screw feeder, mounted cantilever with the gap relatively casing. Initial data for building the mathematical model were: screw rotation angle speed, feeder screw diameter, helical line pitch of the feeder screw turn, material part parameters. This model can be used for interpreting the design-kinematic parameters of the pneumatic-mechanic transporter. Graphs of dependence of the angle change deflection and the screw angle speed on the time of the screw turn rotation under vibration processes have been built. Source

The article presents the design of a safety device with slipping and axial shifting regimes, which are separated in time and are used in order to recondition the working capacity of a conveyer. Also, power analysis of the operation of a safety mechanism is conducted, which gives the opportunity to estimate the change in the moment of rotation of a driven half-clutch and a screw T depending on the change in the angle of the relative turning of half-clutches ? . Based on the results of the static experimental investigation of the safety device, it was determined that the given static analytical dependences can be used in the engineering design of different standard sizes of a safety device.

The analysis of known reciprocating screw working parts with flexible helical surfaces and screw conveyer operation has been carried out. A new structure of reciprocating screw with flexible helical surface and its manufacturing method have been proposed. The bench has been developed and manufactured for conduction of experimental researches. Experimental findings have been provided considering the definition of influence on the value of flexible sheet deformation, its width and cantilevered cog size as well as comparative results of grain material destruction degree with rigid and flexible reciprocating screw working surfaces.
