[0022] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0023] like Figure 1 As shown, the concrete separation and recovery device of the present application includes a drum screen 1, an under-screen belt 2, an over-screen belt 3, a feeding belt 4 and a storage bin 5. The under-screen belt 2 is arranged at the lower part of the drum screen 1, the over-screen belt 3 is arranged at one end of the drum screen 1 and is perpendicular to the drum screen 1, one end of the under-screen belt 2 is arranged at the upper part of one end of the feeding belt 4, and the other end of the feeding belt 4 is arranged at the upper part of the storage bin 5.

[0024] During operation, concrete enters drum screen 1, where it separates fine concrete from coarse concrete (lumps). Fine concrete falls from the bottom of drum screen 1 onto under-screen belt 2, which carries it to feeding belt 4, which then carries it to storage bin 5. Coarse concrete exits the end of drum screen 1 and falls onto over-screen belt 3, which transports it to the next process. This completes the separation and recovery of coarse and fine concrete aggregates, allowing both fine and coarse aggregates to be reused.

[0025] like Figure 3As shown, in one embodiment of the present application, a drum screen 1 includes a drum support 11, a drum 12, a first drive motor 13, and rollers 14. Four rollers are typically provided on the drum support 11, one of which is a drive roller. The rollers 12 are supported by the rollers 14. The rollers 12 are provided with multiple screen holes, the size of which is determined based on the requirements for concrete separation. The first drive motor 13 is provided on the drum support 11 and is used to drive the drive rollers, which in turn drive the drum 12 to rotate. To improve the drive roller's drive of the drum 12, gears can be provided on the drum 12, and similarly, gears can be provided on the drive rollers, with the two meshing together.

[0026] A screen cavity 15 is formed in the drum support 11 below the drum 12, and the screen belt 2 is arranged in the screen cavity 15. An upper screen belt support 16 is arranged at one end of the drum support 11, and the upper screen belt support 16 is used to fix the upper screen belt 3. A drum screen cover 17 is arranged above the drum 12 and on both sides. The drum screen cover (17) is arranged on the drum support 11 to prevent dust from being raised during screening.

[0027] like Figure 2 As shown, in one embodiment of the present application, the feeding belt 4 includes a belt support 41, a second drive motor 42, a first running wheel 43, a first folding support 44, a second folding support 45, a second running wheel 46, and a slide 47. The belt support 41 is tilted, with one end higher than the other. A belt is mounted on the belt support 41. A second drive motor 42 is disposed at the upper end of the belt support 41 to drive the belt to rotate. The first running wheel 43 is disposed below the lower end of the belt support 41. One end of the first folding support 44 is movably connected to the middle of the belt support 41. The other end of the first folding support 44 is movably connected to the second folding support 45. A second running wheel 46 is disposed at the connection. The other end of the second folding support 45 is movably connected to the slide 47, which is parallel to the belt support 41. By sliding the other end of the second folding support 45 in the slide 47, the inclination of the belt support 41, i.e., the feeding height of the belt support 41, can be adjusted.

[0028] In another embodiment of the present application, the feeding belt 4 is provided with a first bracket below the lower end of the belt bracket 41 on the basis of the above composition and function, a first running wheel 43 is provided at the end of the first bracket, and a second bracket is provided at the same time, one end of the second bracket is movably connected to the first bracket, the other end of the second bracket is movably connected to the first folding bracket, one end of the first folding bracket 44 is movably connected to the middle part of the belt bracket 41, the other end of the first folding bracket 44 is movably connected to the second folding bracket 45, a second running wheel 46 is provided at the connection, and the other end of the second folding bracket is movably connected to the slide 47. In this way, while the belt bracket 41 is adjusted by sliding one end of the second folding bracket 45 on the slide 47, the first folding bracket 44 drives the second bracket to move, thereby driving the adjustment of the first running wheel 43.

[0029] In one embodiment of the present application, the storage bin 5 is provided with multiple bins, so that concrete of different particle sizes or types can be packed.
