C. In the invention, when the mud scraping plate is pushed forwards, the roller contacts the bottom of the tank before the mud scraping plate contacts the bottom of the tank, so that a gap is formed between the bottom of the mud scraping plate and the tank bottom, the direct contact is avoided, and the roller supports the mud scraping plate to roll forwards in the advancing process of the mud scraping vehicle driving the mud scraping plate, so that the advancing resistance is reduced, the abrasion to the bottom of the mud scraping plate can be reduced, the energy consumption is reduced, the gap is controlled within a reasonable range, and the sludge is prevented from passing through the gap.

D. In the process of pushing the sludge plate, the roller drives the sawing rope to rotate around the periphery of the sludge plate, so that the sludge in the large caking at the bottom of the sedimentation tank can be cut into small fine lumps, the collection of the sludge plate is facilitated, and the phenomenon that the forward direction of the sludge plate is blocked by massive sludge is avoided.

E. The sawing rope is prevented from cutting the mud scraping plate, the rotary drum, the roller and the like, and the running smoothness of the sawing rope is improved.

F. When the mud scraping plate pushes the mud to advance, the mud cleaning plate is extruded to lift up around the sliding groove, and after the mud is pushed into the mud hopper, the mud cleaning plate falls due to the action of gravity in the returning process of the mud scraping plate, and then the sticky mud adhered to the outer surface of the mud scraping plate is cleaned.

G. The arc cover moves up under the promotion of mud scraper, when removing to the top, can cover the mud scraper upper end, has expanded the space of mud scraper, and avoids mud on mud scraper upper portion to cross from the upper end, simultaneously, prevents to cause the stirring to the quality of water of top at mud scraper propulsion in-process, avoids causing secondary pollution to the quality of water after the mud scraper top deposits.

H. The setting on two first pivots is guaranteed unanimously, is favorable to strengthening the effect of cleaing away to the sedimentation tank bottom, and is favorable to maintaining the equilibrium and the stability of mud scraper operation process.

Further, when the mud scraper 8 pushes the mud to advance, the mud cleaning plate 35 is extruded to lift up around the chute 34, and after the mud is pushed into the mud bucket, the mud scraper 8 returns the in-process, the mud cleaning plate 35 falls due to the action of gravity, and then the sticky mud adhered to the outer surface of the mud scraper 8 is cleaned.

Further, arc cover 37 shifts up under clear mud board 35's promotion, when removing to the top, can cover 8 upper ends of mud scraper, has expanded the space of mud scraper 8, and avoids mud on 8 upper portions of mud scraper to cross from the upper end, simultaneously, prevents to cause the stirring to the quality of water of top in 8 propulsion processes of mud scraper, avoids causing secondary pollution to the quality of water after 8 tops of mud scraper deposit.

Further, the setting of two first pivots 6 is guaranteed unanimously, is favorable to strengthening the effect of cleaing away to the sedimentation tank bottom, and is favorable to maintaining the equilibrium and the stability of 2 operation processes of mud scraping car.

The working principle is as follows:

The embodiments of the present invention are disclosed as the preferred embodiments, but not limited thereto, and those skilled in the art can easily understand the spirit of the present invention and make various extensions and changes without departing from the spirit of the present invention.
