Description

TECHNICAL FIELD

[0001] The application relates to the technical field of concrete preparation, in particular to a sandstone automatic sorting and cleaning integrated device for concrete preparation. BACKGROUND

[0002] Concrete is one of the most important civil engineering materials in the contemporary era. Concrete aggregate refers to granular loose materials that play a skeleton or filling role in concrete. It is divided into coarse aggregate and fine aggregate. Coarse aggregate refers to pebbles, gravel and the like, and fine aggregate refers to natural sand, artificial sand and the like.

[0003] The existing patent (publication number: CN217830142U) discloses a concrete sandstone fine aggregate sorting device, which belongs to the technical field of concrete aggregate sorting. A feeding hopper is fixedly connected to the upper portion of a box body and communicates with the box body. Two powdering rollers are rotatably connected in the feeding hopper and are arranged in parallel. The two powdering rollers are drivingly connected. A driving motor is fixedly connected to the outside of the feeding hopper and the box body. The driving motor is fixedly connected to one of the powdering rollers. An inclined screen is arranged in the box body. A reciprocating mechanism is arranged on the side of the screen close to the driving motor. A transmission mechanism is arranged between the driving motor and the one powdering roller. The reciprocating mechanism and the one powdering roller are connected by the transmission mechanism. The powdering roller is used for powdering, and the screen reciprocates at the same time, so that the aggregate is screened. Compared with the general situation, the coarse and fine aggregates are screened after being crushed and pulverized and then transported to the screening device, so that the quality of the prepared concrete is improved.

[0004] The above sorting device realizes the powdering of the powdering roller and the reciprocating movement of the screen at the same time by arranging the reciprocating mechanism and the one powdering roller connected by the transmission mechanism, so that the aggregate is screened. Compared with the general situation, the coarse and fine aggregates are screened after being crushed and pulverized and then transported to the screening device, so that the quality of the prepared concrete is improved. However, the aggregate often has impurities such as mud and dust during collection, transportation and processing. These impurities not only affect the quality of the concrete, such as reducing the strength and durability of the concrete, but also may cause defects such as air bubbles and cracks during the molding of the concrete, thereby affecting the overall performance and service life of the concrete product. The above device lacks cleaning of the aggregate. Practical new type content
