[0020] The utility model provides a technical solution: as Figures 1 to 4As shown in the figure, in this embodiment, a crushing device for concrete production includes a crushing box 1. A crushing mechanism is arranged inside the crushing box 1. The bottom of the crushing box 1 is fixedly connected with a bottom plate 16. The upper end of the crushing box 1 is fixedly connected with a material metering box 7. Above the material metering box 7, there is a storage box 6. A rotating groove 13 is opened inside the material metering box 7. A rotating roller 10 is rotatably connected in the rotating groove 13. Aggregate grooves 11 are opened on the outer wall of the rotating roller 10. A second motor 5 is fixedly connected to the outer wall of the material metering box 7. The output shaft of the second motor 5 penetrates the side wall of the material metering box 7 and is fixedly connected to the center of the shaft end of the rotating roller 10.

[0021] Among them, the crushing mechanism is composed of a first motor 4, transmission gears 12 and crushing rollers 15. The two crushing rollers 15 are rotatably installed inside the crushing box 1. The first motor 4 is fixedly connected to one side wall of the crushing box 1. Two transmission gears 12 are rotatably connected to the other side wall of the crushing box 1. The output shaft of the first motor 4 is fixedly connected to the center of the shaft end of one crushing roller 15. The two transmission gears 12 are respectively fixedly connected to the shaft ends of the two crushing rollers 15, and the two transmission gears 12 are meshed with each other.

[0022] During use, start the first motor 4 to drive one crushing roller 15 and one transmission gear 12 to rotate, thereby driving the other transmission gear 12 and the other crushing roller 15 to rotate.

[0023] Among them, on the upper sides of the two symmetrical inner walls of the crushing box 1, guide plates 14 are fixedly connected. The guide plates 14 are inclined downward towards the middle of the crushing box 1. A guide plate 9 is arranged at the bottom opening position of the crushing box 1.

[0024] By arranging the guide plates 14, the material can fall towards the position between the two crushing rollers 15. By arranging the guide plate 9, the crushed material can slide down along the guide plate 9.

[0025] Among them, the bottom cavity of the storage box 6 is inclined and inclined downward towards the direction of the material metering box 7.

At this time, the second motor 5 is started to drive the rotating roller 10 to rotate. When the aggregate groove 11 on the rotating roller 10 rotates to the bottom, the material in the aggregate groove 11 will fall into the crushing box 1. The crushing mechanism in the crushing box 1 will crush the material. By continuously rotating the rotating roller 10, the material can be intermittently fed into the crushing box 1. By controlling the rotation speed of the second motor 5, the purpose of controlling the material feeding speed can be achieved, so that the material feeding speed and the working efficiency of the crushing mechanism in the crushing box 1 reach a balance, avoiding the problem of too slow or too fast material feeding.
