8. The sludge conveying apparatus according to claim 1, wherein: the utility model discloses a material mixing machine, including bottom plate (1), lie in on bottom plate (1) and install refining mechanism (19) between drive roller (3) and driven roller (6), refining mechanism (19) are including fixed mounting Contraband shape frame (191) on bottom plate (1) and the opening down, 21274, fixed mounting has refining motor (192) on the horizontal segment of shape frame (191), the output fixed mounting of refining motor (192) has vertical axle (193), evenly fixed mounting has a plurality of refining boards (194) that lie in conveyer belt (7) top along its circumference on vertical axle (193).
9. A method for sludge transportation, which is carried out by using the sludge transporting apparatus according to claim 1, comprising the steps of:
step one, adjusting the position: adjusting the position of the bottom plate (1) to enable the discharge hole (101) to be aligned with a feeding hole of the concentration device, and driving a bidirectional screw rod (809) to rotate through a rotating knob (810), so that two guide plates (808) are driven to move oppositely until the guide plates (808) reach positions corresponding to the guide rods (806);
step two, conveying sludge: the driving roller (3) is driven to rotate by the driving motor (4), so that the driven roller (6) is driven to synchronously rotate by the conveyer belt (7), sludge is conveyed onto the conveyer belt (7) by manpower or sludge suction equipment and is conveyed by the conveyer belt (7), and the sludge is separated from the conveyer belt (7) under the action of self gravity above the discharge port (101);
step three, sludge scraping and cleaning: the mud scraping cylinder (802), the mud scraping plate (804), the return spring (805) and the guide rod (806) are driven to synchronously rotate by rotating the mounting shaft (801), and residual mud on the surface of the conveying belt (7) is scraped by the mud scraping plate (804); the guide rod (806) is guided by the guide plate (808), so that the mud scraping plate (804) is retracted into the strip-shaped groove (803), and the mud adhered to the mud scraping plate (804) is removed.
