Conveyer is pressed commonly have without drawing will undertake classified.
Have drawing conveyer includes drawing commonly, bear the weight of component part, actuating device, tension station, change to be mixed to device bearing etc. Drawing in order to delivers traction, can use catenary of conveyer belt, drawing or wire rope; Bear the weight of component part in order to bear put stock, hopper, bracket or spreader wait; Actuating device gives conveyer with motivation, mix by electromotor, reducer commonly brake (stopper) wait for composition; Tension station has screw type and heavy weight type commonly two kinds, can make drawing the pulling force that keeps certain and sag, in order to make sure conveyer runs normally; Bearing in order to bear hold drawing in the palm or bear the weight of component part, can use bearing roller, gyro wheel to wait.
Have drawing the structural characteristic of conveyer is: Outfit of the stock that be carried is in with drawing connect together bear the weight of inside component part, or direct outfit is in drawing (like conveyer belt) on, drawing bypass each platen or chain wheel end to end, form those who include to carry stock to have carry branch and what do not carry stock is empty of branch close annulus road, use drawing successive movement carries stock.
This kind conveyer sort is various, basically have conveyer of belt conveyer, board type conveyer, car type conveyer, automatic staircase, automatic footpath, scraper, bury scraper the conveyer, conveyer that fight form, bucket elevator, pensile conveyer and cableway of built on stilts.
Without drawing the structure of conveyer comprises each not identical, with the working component that will carry stock also not identical. Their structural characteristic is: Use the whirligig of working component or reciprocate, or use medium to make in the flow in conduit stock is carried ahead. For example, the working component of roller conveyer is a series of roller, roller makes whirligig in order to carry stock; The working component of helix conveyer is helix, helix makes whirligig send stock with be being pushed along makings chamfer in makings chamfer; The working component of oscillatory conveyer is makings chamfer, makings chamfer makes reciprocate in order to carry park among them stock.
Of prospective conveyer will side with large change ambassador of development, enlarge to use limits, stock automatic sorting, reduce energy to use up, reduce the respect such as pollution to develop.
Large change include to carry ability, large sheet to pilot is spent and carry a few respects such as dip angle greatly greatly. The stand-alone length that the length of hydraulic conveyor already amounted to conveyer of belt of 440 kilometers above is close already 15 kilometers, already appeared to contact Jia Yi by a certain number of stage composition of two ground " belt is carried " . The more perfect conveyer structure that many countries are exploring Sunday run, large volume to carry stock continuously. Enlarge the scope of application of conveyer, it is to show development can be in what work in the environment of material of mordant, radioactivity, flammability below condition of high temperature, low temperature, and can carry explode fierily, easily, the conveyer of easy cement group, agglutinant stock.
