step 1: materials enter from the opening of the detachable fixing frame (4), the dust concentration detection sensor (2) detects the dust concentration, if the dust concentration is larger than or equal to a set value, the water valve and the telescopic plate control switch (1) are used for controlling the telescopic plate (5) to extend inwards to prevent water mist from being combined with the materials, the small-sized sprayer (3) sprays to realize dust fall, if the dust concentration is smaller than the set value, the water valve and the telescopic plate control switch (1) are used for controlling the telescopic plate (5) to return to an initial state and extend outwards to discharge the water mist and dust combined matter, and the small-sized sprayer (3) stops spraying;
step 2: the material passes through translation conveyer belt (11) and conveys conveyer belt (21), and gear type pushing plate adds holder (7) and rotates through drive gear dish (704), moves along propelling movement track (8) to drive pushing plate (6) along conveyer belt (21) motion and upwards promote the grit of landing, thereby realize wide-angle slope transportation grit.
