▎ 摘　　要

NOVELTY - The vehicle has an impurity collection tube fixed on the top of the transport vehicle body. A filter box (29) is fixed on the outer wall of the top of the impurity collection cylinder. The outer wall of the filter box is welded with the installation pipe. The outer wall of the filter box is fixed with a shell, and the outer wall of one side of the shell is welded with a mounting pipe. A curved filter screen (31) is fixed on the bottom inner wall of the filter box. The peripheral outer wall of the vertical rod (33) is integrally formed with a scraping plate (32) and a semicircular plate (34). An inspection cover is fixed on the top outer wall of the filter box. An arc pressing sheet is movably connected to the inner wall of the arc surface of the filter box. USE - Graphene powder loading and unloading carrier vehicle used in process of transporting and producing graphene powder. ADVANTAGE - The maximum rotation angle of the scraping plate can be limited by setting a blocking column, so as to avoid the arc-shaped pressing sheet in the moving process and scraping plate are crossed with each other. By setting a coil spring can ensure the scrapping plate after limiting, and by setting the V-shaped hole on the pushing plate can drive the L-shaped rod and the pressing sheet to move in the process of scraping the residual impurity of scraping plate surface cleaning. The effect of filtering impurity can be improved. The impurity collecting cylinder can collect the impurity. The power pump is capable of graphene the powder in the storage hopper through negative pressure, through setting the filter screen can be used for cleaning impurity contained in the powder, and graphene the storage cylinder can store the graphene powder. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene powder loading and unloading transportation method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the filter screen installation structure of a graphene powder loading and unloading transport vehicle. 27Ring seat 29Filter box 31Curved filter screen 32Scraping plate 33Vertical rod 34Semicircular plate 35Pressing plate
