Designing Of Hoisting And Transporting Mechanism
For Cabbage Harvest Machinery
Abstract
Farm machinery is to become the capital ship of the agriculture.This paper introduced gathering ,transporting and packing cabbage,on the basis of the working peculiarity of the cabbage harvest machinery,and it mainly introduced its transporting mechanism. The cabbage harvest machinery is suitable to gather in the cabbage for family expenses.
The cabbage harvest machinery use belt conveyors as its transporting mechanism,while Tensioning device, as an important and indispensable component of the belt conveyor, has a vital role to the stable operation of the belt conveyor . This paper introduces the role of the tensioning device,type,installation layout principles, and its development profile.And then raised the tension of the belt conveyor to the tension and take-up device requirements, on the basis the analysis of the principle of the transmission belt conveyor. In this paper, the main device design programme of the automatically tensioning device have been introduced, and descripte its main components for the design and selection of the note.The tensioning device use the screwstaff as the take-up of the implementation component.,with adjustable tension, simple, strong adaptability and control convenience, performance and safety and so on.
