[0013] The technical solution in this application is further described in detail below in conjunction with the accompanying drawings.

[0014] The present application embodiment discloses an impurity screening device for concrete manufacturing. Figure 1 An impurity screening device for concrete manufacturing includes a shell 1 and a screen barrel 2 rotatably arranged in the shell 1, and the screen barrel 2 is arranged obliquely; the shell 1 is provided with a feed port 11 facing the upper port of the screen barrel 2, and the shell 1 is provided with a slag discharge port 13 and a discharge port 12, the slag discharge port 13 faces the lower port of the screen barrel 2, and the discharge port 12 is located below the screen barrel 2; the shell 1 is provided with a motor 3 for driving the screen barrel 2 to rotate.

[0015] The output shaft of the motor 3 is connected to a main gear 21, and the screen barrel 2 is provided with a first slave gear 22 meshing with the main gear 21. The upper and lower ports of the screen barrel 2 are cylindrical structures, and the rest of the middle of the screen barrel 2 is evenly arranged with meshes. The first slave gear 22 is sleeved on the outer peripheral surface of the screen barrel 2.

[0016] The feed port 11 is used to inject concrete, and the concrete falls directly into the screen barrel 2. The motor 3 is started to drive the first slave gear 22 to rotate through the main gear 21, and the first slave gear 22 drives the screen barrel 2 to rotate. The concrete rolls along with the screen barrel 2 and falls along the screen mesh on the screen barrel 2, and is finally discharged from the discharge port 12. The impurities in the concrete roll along with the rotation of the screen barrel 2 and are discharged from the lower port of the screen barrel 2.

[0017] Furthermore, a rotating shaft 4 is rotatably provided in the housing 1 , a rubber slapping rod 41 for slapping the screen barrel 2 is fixedly provided on the rotating shaft 4 , and a second slave gear 42 meshingly connected with the main gear 21 is provided on the rotating shaft 4 .

[0018] The rotating shaft 4 is located above the screen barrel 2 to prevent the falling concrete from being blocked. The rotating shaft 4 is parallel to the axis of the screen barrel 2. After the motor 3 rotates, the rotating shaft 4 is driven to rotate through the main gear 21 and the second slave gear 42, and the rotating shaft 4 drives the rubber slap rod 41 to rotate. In this way, the same motor 3 can be used to drive the screen barrel 2 and the rotating shaft 4 to rotate at the same time. At the same time, the circumference of the second slave gear 42 is smaller than the circumference of the first slave gear 22, so that the rotating shaft 4 can rotate faster and the rotating shaft 2 can rotate slower. The rubber slap rod 41 hits the screen barrel 2 to reduce the blockage of the mesh on the screen barrel 2.

[0019] In the present invention, unless otherwise specified and limited, the terms "connection", "setting" and the like should be understood in a broad sense. For example, "setting" can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium, unless otherwise specified. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
