[0002] Waste concrete refers to a large amount of concrete waste generated during the demolition, reconstruction, or repair of buildings. If this waste is not handled properly, it will not only occupy a lot of land resources, but may also pollute the environment. Through effective recycling and reuse technologies, waste concrete can be transformed into valuable resources.
[0003] The current waste concrete treatment process usually involves crushing and screening the waste concrete. However, the traditional crushing and screening process needs to be carried out in two steps, resulting in a discontinuous treatment process that affects the efficiency of waste concrete treatment and needs to be improved.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.
[0024] like Figure 1 , Figure 2 As shown, a waste concrete separation device for concrete processing includes a support frame 1, a crushing box 2, a screening box 3, and a screen plate 4.
[0025] like Figure 1 , Figure 2 As shown, the support frame 1 is vertically installed on the ground, and the crushing box 2 is installed on the upper end of the support frame 1. The upper end of the crushing box 2 is provided with a feed inlet 21, and the lower end is provided with a discharge outlet 22. Rotary shafts 23 are rotatably connected to both sides of the feed inlet 21. A torsion spring 24 is provided at the end of the rotating shaft 23, and a stop bar 25 is crosswise installed on each pair of rotating shafts 23. The end of the stop bar 25 is set at an angle.
[0026] like Figure 1 , Figure 2 As shown, the screening box 3 is located at the lower end of the support frame 1, and its upper end is connected to the discharge port 22. The screen plate 4 is inclinedly arranged inside the screening box 3, and the lower end of the screen plate 4 is horizontally connected to the discharge plate 41 that penetrates the screening box 3.
[0027] When waste concrete is crushed, it is fed into the feed inlet 21. The waste concrete presses the baffle 25 downward and flips it. After the waste concrete falls into the crushing box 2, the torsion spring 24 controls the baffle 25 to move in the opposite direction and blocks the feed inlet 21 to prevent debris from splashing during crushing and ensure stable separation of concrete.
[0028] The waste concrete is then crushed using the crushing rollers in the crushing box 2. After being screened by the screen plate 4, the large aggregate particles are discharged along the discharge plate 41, and the small aggregate particles are discharged along the discharge port 22, thus completing the automatic screening of the crushed waste concrete.
[0029] Therefore, by setting up a separation device that integrates crushing and screening, continuous crushing and screening of waste concrete can be achieved, combining the two processes into one and improving the processing efficiency of waste concrete.
[0030] like Figure 1 , Figure 2 As shown, the screen disc 4 is horizontally slidably connected to the screening box 3. The screen disc 4 is provided with oriented hook teeth 42, which allows the screen disc 4 to hook the crushed concrete back to the upper end of the screen disc 4 when it reciprocates, thus achieving full screening. The screening box 3 is rotatably connected to a roller 31 that abuts against the lower end face of the discharge disc 41, making the movement of the screen disc 4 smoother.
[0031] like Figure 1 , Figure 2 As shown, a pair of guide rods 43 that penetrate the screening box 3 are horizontally arranged at the upper end of the screen plate 4. A pressure plate 44 is arranged between the pair of guide rods 43. A spring 45 located between the screening box 3 and the pressure plate 44 is sleeved on the guide rods 43.
[0032] like Figure 1 , Figure 2As shown, the screening box 3 is equipped with a drive mechanism 5 for controlling the horizontal sliding of the pressure plate 44. The drive mechanism 5 includes a motor 51 and a cam 52. The motor 51 is located on the outside of the screening box 3, and the cam 52 is located on the motor 51 and abuts against the outer wall of the pressure plate 44.
[0033] When screening waste concrete, the motor 51 is started, which drives the cam 52 to rotate. The cam 52 presses the pressure plate 44 and the guide rod 43 to slide horizontally. The guide rod 43 drives the screen plate 4 to slide, and under the action of the spring 45, the reciprocating sliding control of the screen plate 4 is realized. This can accelerate the screening efficiency of the crushed concrete, make the concrete screening more thorough, and achieve stable grading and screening.
[0034] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
