Abstract
The application discloses a lifting device for rice production and processing, and relates to the technical field of agricultural product transportation, which comprises a conveying bin and a conveying auger arranged in the conveying bin, the bottom of the conveying bin is provided with a feeding hopper, and the top end of the conveying bin is provided with a discharging port; the lifting device further comprises a driving motor and a transmission part; the driving motor is fixedly arranged at the top end of the conveying bin through a motor mounting plate; the transmission part comprises an output shaft, a rotating sleeve and a torsion trigger assembly; the lifting device is improved in view of the fact that, in the prior art, a screw conveyor (auger) is a key equipment for realizing material lifting in rice processing and production, but the screw conveyor is prone to blockage due to changes in material properties (such as excessive humidity and caking) or mechanical failures in actual operation, which leads to overload damage of the driving motor and affects production continuity, equipment safety and other problems; the lifting device has the advantages that the mechanical overload protection structure is used to realize automatic overload protection, and the lifting device has the advantages of improved reliability, production continuity and automation level.
