[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: the above device is not convenient for separating and discharging the crushed concrete during use; if there is a large amount of dust in the concrete gravel, it will cause a lot of pollution to the working environment, and it is also necessary to lay spray equipment to suppress the dust, which increases the cost of the enterprise. Therefore, further improvement is needed. Utility Model Content

[0005] The utility model provides a concrete recycling device, which solves the problem in the related art that it is inconvenient to separate and discharge concrete gravel and suppress dust.

[0006] The technical solution of the utility model is as follows:

[0007] A concrete recycling device comprises a shell, a conveyor belt is fixedly installed on one side of the exterior of the shell, a motor is fixedly connected to one side of the exterior of the shell, the motor is fixedly connected to a rotating rod via an output shaft, a cam is fixedly connected to the outside of the rotating rod, a limit plate is fixedly connected to one side of the interior of the shell, a rotating frame is provided on the top of the limit plate, a steel mesh is embedded in the rotating frame, a rotating shaft is provided on one side of the exterior of the rotating frame, the rotating shaft and the shell are connected by a bearing, a guide plate is provided on one side of the exterior of the rotating shaft, the rotating frame and the guide plate are rotatably connected by the rotating shaft, a fixed plate is fixedly connected to the inside of the shell, two springs are fixedly connected to one side of the fixed plate, and a buffer plate is fixedly connected to one side of the two springs.

[0015] The working principle and beneficial effects of the utility model are as follows:

[0016] In the utility model, since the dust is screened off in advance, in order to ensure that the gravel does not cause impact damage to the conveyor belt, the concrete gravel will continuously contact the buffer plate during the movement, and then the buffer plate will rotate and drive the spring to perform compression work, thereby achieving the buffering work of the concrete, preventing the strong impact force from causing damage to the surface of the conveyor belt, and solving the problem of inconvenient material separation and dust suppression for concrete gravel;

When the concrete completely falls out of the bearing plate, the rubber strip will drive the bearing plate to reset. During the reset process, the bearing plate will be limited by the positioning plate, thereby achieving the reset of the bearing plate and the buffering of the concrete to prevent damage to the steel mesh.

[0024] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0025] like Figures 1 to 3As shown, this embodiment proposes a concrete recycling device, including a shell 1, a conveyor belt 2 is fixedly installed on one side of the outside of the shell 1, a motor 3 is fixedly connected to one side of the outside of the shell 1, the motor 3 is fixedly connected to a rotating rod 4 through an output shaft, a cam 5 is fixedly connected to the outside of the rotating rod 4, a limit plate 6 is fixedly connected to one side of the inside of the shell 1, a rotating frame 7 is provided on the top of the limit plate 6, a steel mesh 8 is embedded in the rotating frame 7, a rotating shaft 9 is provided on the outside of the rotating frame 7, the rotating shaft 9 and the shell 1 are connected through a bearing, a guide plate 10 is provided on the outside of the rotating shaft 9, the rotating frame 7 and the guide plate 10 are rotatably connected through the rotating shaft 9, a fixed plate 11 is fixedly connected to the inside of the shell 1, two springs 12 are fixedly connected to one side of the fixed plate 11, and a buffer plate 13 is fixedly connected to one side of the two springs 12.

[0026] In this embodiment, the rotating rod 4 extends into the interior of the housing 1 and is connected to the housing 1 via a bearing. The bottom of the rotating frame 7 contacts the top of the limiting plate 6, which can facilitate the rotation and support work of the rotating rod 4.

[0027] In this embodiment, the two springs 12 are symmetrically distributed, and the buffer plate 13 and the housing 1 are movably connected via a rotating shaft, which can facilitate the rotation of the buffer plate 13.

[0028] During use, when concrete needs to be recycled, the staff first needs to pour the crushed concrete into the interior of the shell 1 through external equipment, and then the staff turns on the motor 3. After being turned on, the motor 3 will synchronously drive the rotating rod 4 to rotate, and the rotating rod 4 will synchronously drive the cam 5 to rotate during the rotation process. The cam 5 will continuously drive the rotating frame 7 and the steel mesh 8 to move upward during the rotation process. The steel mesh 8 will vibrate up and down during the continuous movement. When the concrete falls on the top of the steel mesh 8, the concrete will continue to vibrate to separate the concrete and dust. Therefore, the fallen dust will be concentrated inside the guide plate 10 for guided discharge, thereby preventing the environment from being polluted due to the large amount of dust during the transmission of the conveyor belt 2.

[0029] In order to ensure that the conveyor belt 2 is not seriously damaged, the concrete gravel will continuously contact the buffer plate 13 during the movement, and then the buffer plate 13 will rotate and drive the spring 12 to perform compression, thereby achieving the buffering effect on the concrete and preventing the strong impact force from causing damage to the surface of the conveyor belt 2. Example

[0030] like Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a connecting plate 14 is fixedly connected to the inside of the shell 1, and a supporting plate 15 is movably connected to the inside of the connecting plate 14 through a rotating shaft, which can facilitate the connection work of the supporting plate 15.

[0031] In this embodiment, a plurality of through slots are provided inside the bearing plate 15 , and fixed shells 16 are fixedly connected to both sides of the interior of the shell 1 , so as to facilitate the discharge of part of the concrete through the through slots.

[0032] In this embodiment, a rubber strip 17 is movably connected to the interior of the fixed shell 16 via a rotating shaft, and movable hinges are fixedly connected to both sides of the top of the supporting plate 15 to facilitate the connection of the rubber strip 17 .

[0033] In this embodiment, the two rubber strips 17 are fixedly connected to the two movable hinge seats respectively, and the positioning plates 18 are fixedly connected to both sides of the connecting plate 14, which can facilitate the fixed connection work of the positioning plates 18.

[0034] In this embodiment, the bottoms of the two positioning plates 18 are in contact with both sides of the top of the supporting plate 15 respectively, and the rubber strips 17 are in an undeformed state, which makes it easier for the positioning plates 18 to support the supporting plate 15 .

[0035] During use, when concrete enters the shell 1 in batches, the concrete will first come into contact with the supporting plate 15, and part of the concrete will be discharged through the through groove inside the supporting plate 15. Then the supporting plate 15 will rotate downward by gravity. During the rotation, the supporting plate 15 will synchronously drive the rubber strip 17 to stretch. When the concrete completely falls out of the supporting plate 15, the rubber strip 17 will drive the supporting plate 15 to reset. During the resetting process, the supporting plate 15 will be limited by the positioning plate 18, thereby achieving the reset of the supporting plate 15 and the buffering of the concrete to prevent damage to the steel mesh 8.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
