Working process is divided into takes off grain and two sections of walkings.

Take off the grain process: the motor of chain mat machine drives imput shaft and rotates by change speed gear box, belt, belt pulley, sprocket wheel on the imput shaft drives chain, chain forms circulation by polygonal sprocket wheel, pressing sprocket, carrier bar on the chain scrapes grain on the bevelled belt feeder, and belt feeder rises to grain and serves transport trolley behind the certain altitude and drag away.

Walking process: take off a lifting mechanism and will take off head and raise, mention frame front end lifting bar, curved bar is depressed sliding bar, lifts slip cap, and the frame front end is lifted, and starts movable motor, drives trailing wheel, handles the deflecting bar walking.

The utility model advantage is as follows:

1, the polygonal sprocket wheel of chain mat machine makes chain gear stable, and the reliable operation running steadily.

2, chain tension regulating mechanism is regulated very simple.

3, lifting steering hardware cooperative mechanical walking makes machine operation flexible, and labour intensity is low, moves very convenient.

4, optimize the antifriction-bearing box position, pressing sprocket and driven shaft sprocket wheel adopt outstanding axle construction, and space, imput shaft sprocket wheel both sides is big, and bearing is not twined extremely by the fag end of grain the inside, and the fault rate of machine significantly reduces.

The utility model is reasonable in design, output is high, working stability is reliable, fault rate is extremely low.Flexible operation is easy, and what be fit to various Bulk Grains delivers from godown, takes grain out of a granary to sun it, turns over operation such as storehouse.
