[0023] The following is combined with Figure 1-5 This application is described in further detail.

[0024] The present application embodiment discloses a waste concrete separation device for concrete processing. Figure 1 and Figure 2 The waste concrete separation equipment for concrete processing includes a separation box 1, a feed port 2 is provided on the top of the separation box 1, a feed hopper 3 is arranged on the separation box 1 through the feed port 2, a baffle 4 is arranged for rotation in the feed port 2, and the rotation axis of the baffle 4 is parallel to the ground, and an elastic member for driving the baffle 4 to rotate and close the feed port 2 is arranged on the separation box 1, and a baffle 5 is fixedly arranged on the separation box 1 and above the baffle 4, and the bottom surface of the baffle 5 is horizontal, and the baffle 4 abuts against the lower part of the baffle 5 under the action of the elastic member and is in a horizontal state. After the waste concrete is crushed, it is put into the separation box 1, and the concrete falls on the baffle 4. Under the action of the concrete's gravity, the concrete drives the baffle 4 to rotate downward, thereby opening the feed port 2, and thus falls from the feed port 2 into the separation box 1. Subsequently, under the action of the elastic member, the baffle 4 is driven to rotate upward to close the feed port 2, thereby reducing the possibility of dust escaping from the feed port 2; and under the action of the stopper 5, the rotation angle of the baffle 4 is limited, so that the baffle 4 is convenient for closing the feed port 2.
