The connected concrete and steel bars continue to move downward along the inclined surface of the impact block 21. The impact block 21, in conjunction with the housing 1, further extrudes and crushes the concrete. Through the continuous impact of the impact block 21 on the concrete block, the concrete block is broken, and the steel bars encased inside the concrete block are separated from the concrete, facilitating the recycling and reuse of the steel bars. This prevents the inclusion of steel bars in the concrete aggregate and facilitates the re-production of the concrete aggregate.

[0046] Specifically, the construction waste is a block-shaped concrete block encased in steel reinforcement. The volume of the concrete block is adapted to the crushing chamber 11. The shell 1 is processed into a long strip shape. The extrusion plate 2 is adapted to the crushing chamber 11. The impact block 21 adopts a detachable design for easy replacement. The impact block 21 adopts a right-angled trapezoidal design to facilitate the construction waste to slide down the inclined surface of the impact block 21. The drive component 3 is designed to provide power for the movement of the extrusion plate 2.

[0047] In some embodiments, as shown in FIG3, a limiting plate 4 is provided at the bottom end of the driving member 3, and a support pad 41 is disposed between the limiting plate 4 and the driving member 3; the limiting plate 4 has a limiting groove 42, and the housing 1 and the extrusion plate 2 are both located in the limiting groove 42. The side of the housing 1 away from the extrusion plate 2 is fixedly connected to the limiting groove 42, and the limiting groove 42 is used to constrain the distance of the lateral movement of the extrusion plate 2.

[0048] Specifically, the support plate 41 is used to connect the drive component 3 and the limiting plate 4. The limiting groove 42 is processed into a long strip shape. The housing 1 is fixed in the limiting groove 42, and the extrusion plate 2 moves in the limiting groove 42.

[0050] Specifically, the connecting seat 511 connects the limiting plate 4 and the bearing frame 51, the driving wheel 53 and the driven wheel 52 are located on the same horizontal line, the servo motor 532 is connected to the rotating shaft 531 through a coupling, the bearing frame 51 fixes the servo motor 532, and the conveyor belt 54 is used to carry the crushed construction waste.

[0051] It should be noted that the conveyor belt 54 is positioned at a preset height at the discharge end of the housing 1 so that the crushed construction waste falls onto the conveyor belt 54.

[0052] In some embodiments, as shown in FIG4, a plurality of magnets 533 are disposed on the outer periphery of the drive wheel 53, and the plurality of magnets 533 are evenly distributed based on the drive wheel 53.

[0053] Specifically, there are four magnets 533 designed to adsorb adsorbable construction waste such as metal beverage bottles and steel bars. By adsorbing the steel bars with magnets 533, the falling points of concrete and steel bars are changed, thereby separating the concrete and steel bars. In addition, there is no specific limit to the number of magnets 533 used; they can be installed according to usage requirements.

[0054] In some embodiments, as shown in FIG5, a guide member 22 is provided at the bottom end of the extrusion plate 2. The guide member 22 is used to assist the extrusion plate 2 in moving laterally. The guide member 22 includes: a right-angle plate 221, the top end of which is connected to the limiting plate 4 by a second bolt 222, and the right-angle plate 221 is inserted into the bottom groove of the extrusion plate 2; and a plurality of rollers 223, which are connected to the right-angle plate 221 by pins, and the outer periphery of the plurality of rollers 223 abuts against the bottom groove of the extrusion plate 2.

[0055] Specifically, the right-angle plate 221 is adapted to the bottom groove of the extrusion plate 2, and the bottom of the extrusion plate 2 is supported by the right-angle plate 221. The roller 223 is rotatably connected to the right-angle plate 221, and the extrusion plate 2 can move around the outer periphery of the roller 223.

[0056] In some embodiments, as shown in FIG5, a plurality of rollers 223 are evenly distributed along the right-angle plate 221;

[0057] Specifically, four rollers 223 are designed. The rollers 223 assist the extrusion plate 2 in moving laterally and also support the extrusion plate 2.

[0058] In some embodiments, as shown in FIG6, the drive element 3 is a hydraulic rod;

[0059] Specifically, the drive component 3 adopts a hydraulic rod design to facilitate the lateral movement of the extrusion plate 2. In addition, the drive component 3 can also be replaced by other reciprocating structures.

[0060] In some embodiments, as shown in FIG3, the extrusion plate 2 is provided with a slide bar 23, which is slidably connected to the housing 1.

[0061] Specifically, the slide bar 23 is designed with two symmetrically distributed based on the extrusion plate 2. A sliding groove adapted to the slide bar 23 is opened on the top of the housing 1. The slide bar 23 is used to constrain the travel direction of the extrusion plate 2.

[0062] In some embodiments, as shown in FIG2, the impact block 21 is connected to the extrusion plate 2 by a first bolt 211, the first bolt 211 being symmetrically distributed based on the impact block 21.

[0063] Specifically, the design of the impact block 21 being connected to the extrusion plate 2 by the first bolt 211 makes the impact block 21 detachable, which facilitates the replacement of the impact block 21. The design of four first bolts 211 increases the connection strength between the impact block 21 and the extrusion plate 2.

[0064] In some embodiments, as shown in FIG2, the outer wall of the impact block 21 is processed with striped patterns, which are used to increase the friction between the impact block 21 and the construction waste.

[0065] Specifically, the striped design of the impact block 21 is on the side away from the extrusion plate 2. The concave and convex design of the striped pattern is conducive to crushing construction waste.

[0066] The working principle of this application is illustrated below with a preferred embodiment:

[0067] Start the drive unit 3. The output end of the drive unit 3 drives the extrusion plate 2 to move back and forth in the crushing chamber 11 of the housing 1. Then, the connected concrete and steel bars are put into the crushing chamber 11. The extrusion plate 2 and the housing 1 perform initial extrusion on the connected concrete and steel bars. The connected concrete and steel bars continue to move down along the inclined surface of the impact block 21. The impact block 21 and the housing 1 further extrude and crush them. Through the continuous impact of the impact block 21 on the concrete block, the concrete block is crushed, and then the steel bars wrapped inside the concrete block are separated from the concrete.

[0068] After separation, the steel bars and concrete fall along the crushing chamber 11 onto the conveyor belt 54. The servo motor 532 is started, and the output end of the servo motor 532 drives the rotating shaft 531 to rotate in the bearing frame 51 through the coupling. At the same time, the rotating shaft 531 drives the drive wheel 53 to rotate. The conveyor belt 54 rotates between the drive wheel 53 and the driven wheel 52 to transport the separated steel bars and concrete. After the steel bars move to the outer periphery of the drive wheel 53, the magnet 533 located on the outer periphery of the drive wheel 53 attracts the steel bars onto the conveyor belt 54. As the conveyor belt 54 continues to move, the concrete falls naturally. Under the magnetic force of the magnet 533, it needs to travel a certain distance before the magnetic force of the magnet 533 is eliminated and it can fall. The concrete and steel bars fall at different points, thus completing the sorting of concrete and steel bars.

[0069] During the reciprocating movement of the extrusion plate 2 in the crushing chamber 11, the bottom end of the extrusion plate 2 slides along the outer wall of the roller 223, and the top end of the extrusion plate 2 moves in the groove of the housing 1 through the slide rod 23 to constrain the direction of travel of the extrusion plate 2.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
