[0022] In this embodiment, a discharge port communicating with the interior is provided on the left side wall of the box body 1 and near the bottom. A second baffle 3 corresponding to the discharge port is rotatably connected to the left side wall of the box body 1 to prevent a large amount of dust from being discharged through the discharge port during the crushing process. A push plate 5 is slidably connected to the inner bottom of the box body 1 to facilitate users to push out the crushed concrete. A push rod 6 is fixedly connected to the right side of the push plate 5 to facilitate users to push the push plate 5 to move. The right end of the push rod 6 slides through the box body 1.

[0023] In this embodiment, a feeding square pipe 8 communicating with the inside of the box body 1 is fixedly inserted at a position close to the top of the right side wall of the box body 1, which is used to facilitate users to put concrete into the box body 1. The feeding square pipe 8 is inclined to facilitate the concrete to roll and slide into the box body 1. The right end of the feeding square pipe 8 is inclined upward, and the lower end of the feeding square pipe 8 is fixedly connected to a fixing rod for supporting the feeding square pipe 8. The lower end of the fixing rod is fixed to the outer wall of the box body 1.

[0024] In this embodiment, a fixed block 13 is fixedly connected to the inner top of the feeding square tube 8 for supporting the sliding rod 15. A transversely arranged sliding rod 15 is fixedly connected to the right side of the fixed block 13 for supporting and guiding the sliding block 12.
