Firstly, a hopper is arranged at the front end of a shell (1), so that materials fall into an inner cavity of the shell (1), a driving shaft (2) drives a driving chain wheel (3) to rotate clockwise through a gear box (4), a chain (6) pulls a scraper (7) to move under the transmission of a driven chain wheel (517), the scraper (7) at the upper layer moves from back to front, the scraper (7) at the bottom layer moves from front to back, the scraper (7) pushes materials from front to back to move in the shell (1), and the materials fall from the rear side of the shell (1), so that the purpose of conveying the materials is achieved;
Step two, as the upper scraper (7) moves from back to front, the scraper (7) extrudes the plugboard (86), the plugboard (86) is pressed to move towards the inner cavity of the limiting plate (82) due to the inclined arrangement of the limiting plate (82), the height of the plugboard (86) is gradually lowered, the plugboard (86) slides from top to bottom along the outer wall of the scraper (7), materials on the surface of the scraper (7) are removed, in the descending process of the plugboard (86), the included angle between the first connecting rod (83) and the second connecting rod (84) is reduced, the length between the piston cylinder (851) and the piston rod (853) is shortened, when the scraper (7) is separated from the plugboard (86), the piston cylinder (851) and the piston rod (853) are pressed outwards under the action of the elasticity of the second spring (852), the clamping angle between the first connecting rod (83) and the second connecting rod (84) is enlarged, and the plugboard (86) is pushed to move upwards to return to be in preparation for cleaning the scraper (7) again, and materials adhered on the scraper (7) are cleaned;
step three, when the positioning of the supporting seat (514) needs to be released, the push rod (5210) is pushed backwards, the push-pull plate (527) is driven to move towards the rear side, the inclined surface of the inner wall of the guide groove (528) upwards presses the extrusion rod (529), the sliding sleeve (523) upwards slides along the outer wall of the limiting rod (522), the pressing plate (525) enables the second blocking strip (526) to be separated from the first blocking strip (518), and the braking on the supporting seat (514) is released;
step four, rotating the screw rod (512) clockwise, under the limit action of the guide rod (513), the screw thread rotating force of the screw rod (512) drives the supporting seat (514) to move forwards, so that the driven shaft (516) drives the driven sprocket (517) to move forwards, the chain (6) is tensioned, and the moving stability of the scraping plate (7) is improved;
step five, loosening the push rod (5210), wherein the first spring (524) pushes the pressing plate (525) to move downwards, the push-pull plate (527) moves forwards to return along with the downward movement of the extrusion rod (529), the second baffle strip (526) and the first baffle strip (518) are mutually inserted, the moved supporting seat (514) is braked, and tensioning of the chain (6) is completed.
