Description

Concrete sand-stone separator Technical Field The utility model relates to the technical field of sand and stone separators, in particular to a concrete sand and stone separator. Background The concrete sand-stone separator is equipment for separating and recycling sand, stone, aggregate and cement paste in waste concrete, and is widely applied to scenes such as concrete mixing stations, construction sites and the like so as to achieve the purposes of resource recycling and environmental protection. The Chinese patent document with the publication number of CN218423978U discloses a concrete sand-stone separator, wherein the filtering, intercepting and conveying of concrete are realized by arranging a cylinder body and a spiral conveying shaft which are matched with each other; However, the concrete waste contains various waste materials such as gravel, stone, aggregate and the like, and when the sand and stone separation in the concrete waste materials are realized by adopting the mode, large particle waste materials such as the gravel, the stone and the like are directly contacted with the spiral blades in the spiral conveying shaft, so that the situation of blocking and abrasion of the spiral conveying blades is easily caused; And when the scheme realizes that concrete carries out waste recycling, the filtering mode is single, large granular substances such as gravel, stone and the like and small granular substances such as fine aggregate and the like can not be further separated, and the separation effect is poor. Disclosure of utility model (One) solving the technical problems Aiming at the problems in the prior art, the utility model provides a concrete sand-stone separator, which aims to solve the technical problem that the concrete sand-stone separator has poor recovery and separation effects on concrete waste in the prior art in the background art. (II) technical scheme In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides a concrete sand and stone separator, includes the separator box, the separator box top is provided with screening otter board, is provided with elastic support structure between screening otter board and the separator box, just be provided with vibrating motor on the screening otter board, the top of screening otter board is provided with the feeder hopper, be provided with arc filter otter board in the separator box, the coaxial heart in arc filter otter board top is provided with the pivot, the pivot passes through the bearing rotation and sets up on the separator box to the transmission connection is provided with driving motor, cooperation arc filter otter board is provided with screw conveyer blade in the pivot, cooperation arc filter otter board is provided with row material pipe on the lateral wall of separator box, the bottom of separator box is provided with the blow off pipe.
