[0040] like Figures 1 to 3 As shown in this specific embodiment, a concrete crushing and separating device includes a housing 1. The housing 1 is composed of a main cavity 101 with a crushing plate 9 driven vertically by a moving part, a crushing cavity 102 with a main shaft 2 having tooth tips 201, and a separating cavity 103 with an inclined plate 4 having filter holes 401. Adjustment cavities 104 are provided on both sides of the main cavity 101, and the moving part is installed in each cavity. Guide plates 12 are provided on both sides of the main cavity 101 at the lower end of the crushing plate 9 and are rotatably connected to the housing 1. Fixed plates 13 are provided at the lower end of the guide plates 12. The ends of the fixed plates 13 that are far apart from each other pass through both sides of the main cavity 101 and are driven by the moving part. An inclined plate 17 is fixedly provided at the lower end of the crushing cavity 102. A discharge port 106 is provided on one side of the housing 1 located in the separating cavity 103. The inclined plate 4 extends to the outside of the discharge port 106. A recycling box structure is provided at the lower end of the inclined plate 4 in the separating cavity 103.

[0041] Through the above configuration, the moving part 1 and the crushing plate 9 of this utility model can achieve the first crushing of the concrete on the guide plate 12, preventing jamming during subsequent fine crushing and making the crushing more complete. The up-and-down movement of the crushing plate 9 enables the crushing of the concrete to be sealed, effectively preventing concrete from splashing during crushing and making it safer to use. The main shaft 2 and the tooth tip 201 of this utility model can achieve the function of secondary crushing of the concrete, thereby making the crushing more complete. The inclined plate 4 and the filter hole 401 of this utility model can separate the crushed concrete into coarse aggregate and fine aggregate, which is convenient for subsequent use.

[0042] like Figure 2 , Figure 3 and Figure 4As shown, the first moving part includes columns 20 fixedly connected to the upper end of the box 1 on both sides.

[0043] Through the above configuration, the cylinder device 10 of this utility model can drive the crushing plate 9 to move up and down to achieve the first crushing of concrete; the matching configuration of the crushing plate 9 and the feed inlet 105 of this utility model allows the main cavity 101 to be sealed when the crushing plate 9 moves downward; the protrusion 901 strengthens the crushing force of the crushing plate 9 on the concrete, making the crushing more complete; the motor 8 of this utility model can drive the fixing plate 13 to move closer to each other to support the guide plate 12, facilitating the subsequent crushing of concrete on the guide plate 12. The crushing action also causes the fixed plates 13 to move away from each other, allowing the guide plate 12 to fall, thus allowing the crushed concrete to fall into the crushing chamber 102 for the next step of the operation; the support plate 3 of this utility model serves to support the falling guide plate 12, allowing the guide plate 12 to form a certain inclination, so that the concrete can fall precisely between the main shaft 2 and the main shaft 2 for secondary crushing; the motor 2 of this utility model can drive the main shaft 2 to rotate to the opposite side, realizing the secondary crushing of the concrete by the tooth tip 201 and the main shaft 2.

[0044] like Figure 1 , Figure 2 and Figure 5As shown, both the first inclined plate 17 and the second inclined plate 4 are fixedly equipped with vibration motors 16 at their lower ends; the recycling box structure includes a base 5 and a box body 6 embedded in the upper inner groove 501 of the base 5. The lower outer side of the box body 6 is provided with an annular groove 601. The box body 6 is surrounded and fixedly equipped with a retaining ring 24 at the lower end of the annular groove 601. The base 5 is fixed with retaining ring 24 by rotating plates 23 connected to both sides. The upper end of the box body 6 is provided with a semi-circular groove 602. The box body 1 is provided with a sliding outlet 108 corresponding to the positions of the base 5 and the box body 6. The lower end of the base 5 is fixedly equipped with several movable feet 7 with universal wheels 701. The lower end of the box body 1 is provided with sliding grooves 107 corresponding to the positions of the movable feet 7. The base 5 is fixedly equipped with a handle 502 corresponding to the position of the sliding outlet 108; the lower end of the box body 1 is fixedly equipped with several support legs 18. The adjustment cavity 104 is fixedly equipped with a support column 15 between it and the box body 1. Each cavity is provided with a cabinet door 19.

[0045] With the above configuration, the vibration motor 16 of this utility model can drive the first inclined plate 17 and the second inclined plate 4 to vibrate, thereby making the concrete on the first inclined plate 17 and the second inclined plate 4 movable and preventing the concrete from being stuck on the first inclined plate 17 and the second inclined plate 4; the embedded groove 501, the retaining ring 24 and the rotating plate 23 of this utility model can fix the box 6 on the base 5, the semi-circular groove 602 can make the fine aggregate recycling more thorough, and the movable foot 7 and the universal wheel 701 make it convenient for the staff to pull out the base 5 to further recycle the fine aggregate; the cabinet door 19 of this utility model facilitates subsequent maintenance work on different positions of the box 1.

[0046] Working principle: In use, simply ensure that this utility model is in the position of Figure 2In the first stage, the coarse aggregate recycling box is placed on the lower end of the side of the inclined plate 24 extending outside the box body 1. At this time, the cylinder device 10 is activated to drive the crushing plate 9 upward. Then, the concrete to be crushed is placed into the main chamber 101 through the feed inlet 105. The concrete to be crushed will fall onto the guide plate 12. At this time, the cylinder device 10 controls the crushing plate 9 to move up and down repeatedly to crush the concrete for the first time. The upward distance of the crushing plate 9 does not exceed the height of the feed inlet 105, so the crushing plate 9 achieves full coverage of the crushing area. During crushing, the concrete will not splash out, making it safer to use. After the concrete is crushed... The second starter motor drives the main shaft 2 to rotate towards the opposite side, while the first starter motor 8 drives the threaded column 801 to rotate, thereby causing the two fixed plates 13 to move away from each other, so that the fixed plates 13 move into the adjustment cavity 104. At this time, the side of the guide plate 12 that is in contact with the main shaft will fall until it abuts against the support plate 3. The concrete that has been broken in the first stage will fall between the main shafts 2 and 3. The concrete can be broken in the second stage by the squeezing of the tooth tip 201. The concrete will fall onto the first inclined plate 17. The vibration motor 16 is started, and the broken concrete will fall completely onto the second inclined plate 4. The fine aggregate will pass through the second inclined plate 4. The vibrations fall through the filter holes 401 into the semi-circular groove 602 of the box body 6. Coarse aggregate will fall into the first placed recycling box as the inclined plate 4 tilts, thus allowing for the separate recycling of coarse and fine aggregates for convenient subsequent use. When the concrete undergoes secondary crushing, the motor 8 drives the fixed plate 13 back to its original position, which in turn pushes the guide plate 12 back to its original position. Therefore, during secondary crushing, uncrushed concrete can be added again for the first crushing, effectively improving crushing efficiency. After crushing is complete, the recycling box containing coarse aggregate can be directly lifted and recycled. The coarse aggregate particles are larger than... Fine aggregate will not remain in the gaps of the recycling box. To recycle the fine aggregate, simply pull out the base 5 using the handle 502, rotate the rotating plate 23 so that the rotating plate 23 moves away from the retaining ring 24, and then remove the box body 6 to pour out the fine aggregate. The semi-circular groove 602 can effectively prevent the fine aggregate from remaining in the gaps of the box body 6. After pouring out, put the box body 6 back and push the base 5 back to its original position. The universal wheel 701, cabinet door 19, latch, vibration motor 16, cylinder device 10, motor one 8, motor two, and their electrical connection lines and methods are all disclosed in the prior art, so this application will not elaborate further.

[0047] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
