[0004] For the prior art, although the helical blade can stir the material entering the left end of the tank body when rotating, so that the mud on the surface of the material is removed, however, the material can be directly carried by the helical blade to move towards the right end of the tank body, that is, a higher position, so that part of the material can directly leave the water surface without being washed, so that the surface of the material is easy to have mud remaining, in addition, the two helical blades arranged in the tank body do not realize the classified conveying of the material, so that if the gap of the helical blade is too large, the small-particle material is easy to leak, and if the gap of the helical blade is too small, the large-particle material is easy to be stuck in the blade.

[0005] The utility model discloses a recycled aggregate water washing device, which is characterized by installing a leaching mechanism on the machine body, so that the material can still be washed after leaving the water surface, ensuring the cleaning effect, in addition, the helical blade classifies and conveys the material, avoiding the problems of material leakage or material sticking. UTILITY MODEL CONTENTS

[0008] The rinsing mechanism comprises a water pump, a water pipe and a rinsing head, wherein the rinsing head is fixed inside the water washing pool, the water pipe is connected between the rinsing head and the water pump, and the water pump is fixed with the sewage pool for pumping water from the sewage pool.

[0009] Compared with the prior art, the utility model has the beneficial effects that:

[0010] 1、In the prior art, the spiral blade is easy to cause part of the aggregate to separate from the water surface without being fully washed, resulting in residual sludge. The utility model adds a rinsing mechanism in the water washing pool, uses the water pump to pump water from the sewage pool, and transports the water to the rinsing head fixed in the water washing pool, so as to perform secondary flushing on the aggregate separated from the water surface. The aggregate is ensured to be washed by water flow during the rising process, and the sludge is separated in real time by the first filter screen, so that the surface residual sludge is effectively eliminated, and the cleaning quality is significantly improved.

[0011] 2、The utility model realizes the effect of the hierarchical screen and the double-spiral roller linkage structure that: after the aggregate is introduced into the inclined hierarchical screen through the feeding hopper, the large-particle aggregate falls into the coarse-roller conveying groove, and the small-particle aggregate enters the fine-roller conveying groove, so that the precise shunting is realized, the fine aggregate and the coarse aggregate are conveyed through the fine roller and the coarse roller respectively, the small-particle material loss is avoided, the large-particle material jamming is prevented, and the conveying stability and efficiency are significantly improved.
