In the particular use of the present invention,

the even first auger 2 of mechanism and the even operation of second auger 3 can be made a stall to the concrete for the concrete removes to central authorities or both sides, thereby make the less place of concrete can supply the concrete, guarantee the level and smooth on concrete surface layer as far as possible, and puddler 5 inserts the concrete when the rabbling mechanism rotates, stirs the concrete, makes the concrete surface by the stirring, and last leveling plate 6 through leveling mechanism is with the upper surface flattening.

For realizing spreading out the even to the concrete, spread out even mechanism including fixing at the first support 8 of fixed plate 1 below, be fixed with first motor 9 on the first support 8, first motor 9 drive first auger 2 and second auger 3 rotate, first auger 2 both ends are equipped with the spiral board that revolves to opposite, promote the concrete and remove to both sides when first auger 2 rotates, second auger 3 and the spiral board opposite direction on the first auger 2, promote the concrete and remove to central authorities when second auger 3 rotates.

First auger 2 promotes the concrete to both sides, and second auger 3 promotes the concrete to central authorities, has realized the removal of concrete to make the concrete stand evenly, final concrete is located central position, and unnecessary concrete can be taken away by screed 6, deviates from the edge when avoiding being located both sides, leads to the concrete surface unevenness.

For the realization is to the stirring of concrete, rabbling mechanism is including fixing second support 10 in fixed plate 1 below, be fixed with second motor 11 on the second support 10, second motor 11 drive rotary drum 4 rotates, 4 inside pivot 12 of being connected with the transmission of second motor 11 that are equipped with of rotary drum, rotary drum 4 and the reverse coaxial rotation of pivot 12, be equipped with first gear 13 between pivot 12 and the rotary drum 4, rotary drum 4 includes the mounting panel 14 that a plurality of intervals set up, puddler 5 rotates and sets up on mounting panel 14, puddler 5 the inner is equipped with
