Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.
[0016] A construction waste crushing device for construction engineering, such as Figure 1 As shown, it includes a box body 1, a feed port 2 is provided at the top of the box body 1, a pre-crushing mechanism is arranged in the box body 1, a horizontal plate 3 is fixedly installed in the box body 1, a plurality of through holes are provided on the top surface of the horizontal plate 3, the horizontal plate 3 is located below the pre-crushing mechanism, a crushing mechanism is arranged in the box body 1, the crushing mechanism is located below the horizontal plate 3, a rotatable support plate 4 is movably installed in the box body 1, the support plate 4 is located below the crushing mechanism, a discharge port 5 is provided at the bottom end of one side of the box body 1, a shielding plate is hingedly installed at the top of the discharge port 5, a pushing mechanism is slidably installed on the inner wall on the other side of the box body 1, the pushing mechanism can push the material out of the box body 1 from the discharge port 5 and adsorb the magnetic metal material. Pour construction waste into the box 1 from the feed inlet 2, and the construction waste is pre-crushed by the pre-crushing mechanism to crush large pieces of construction waste into small pieces. The small pieces of construction waste fall downward from the through hole and fall onto the top surface of the support plate 4. Then the crushing mechanism crushes the small pieces of construction waste to crush the small pieces of construction waste more thoroughly. The support plate 4 rotates downward, and the crushed smaller pieces of construction waste slide off the support block 4 and fall into the bottom end of the box 1. Then the pushing mechanism absorbs the metal substances in the construction waste and pushes the crushed construction waste out of the box, and transports the crushed construction waste to the next process. At the same time, the magnetic metal substances are also separated from the construction waste, and the magnetic metal waste is recycled.
[0017] Specifically, the pushing mechanism described in this embodiment includes a moving part and an adsorption part;
[0018] The moving part includes a plurality of first cylinders 6, one end of the fixed end of the first cylinder 6 is fixedly connected to the inner wall of the other side of the box body 1, and the moving ends of the plurality of first cylinders 6 are fixedly connected by a connecting plate 7, and an inclined plate 8 is fixedly installed on the top surface of the connecting plate 7;
[0019] The adsorption part is installed on the connecting plate 7 .
[0020] In the process of the crushed construction waste sliding down from the support plate 4, the top surface of the inclined plate 8 contacts the inner wall of the other side of the box body 1. Guided by the inclined plate 8, the construction waste moves to the right side of the connecting plate 7. After the support plate 4 returns to a horizontal state, the first cylinder 6 extends to push the adsorption part to move toward the discharge port 5, and at the same time adsorbs the magnetic metal in the construction waste. After the adsorption is completed, the adsorption part contacts the shielding plate and lifts the shielding plate, that is, the shielding plate is folded outward with the hinge point with the discharge port as the center, and the discharge port is exposed. The connecting plate 7 pushes the construction waste out of the box body 1, and the adsorption part is partially exposed outside the box body 1. After the transportation of the material without magnetic metal is completed, the magnetic metal material on the adsorption part is cleaned, and the construction waste is classified and processed.
[0021] Furthermore, the adsorption part described in this embodiment includes a rotating motor fixedly mounted on one side of the connecting plate 7, a disc is rotatably mounted on the other side of the connecting plate 7, the output shaft end of the rotating motor passes through the connecting plate 7 and is fixedly connected to the center of the disc, and a plurality of long strip electromagnets 16 are fixedly mounted at the eccentric position of one side of the disc. The rotating motor drives the disc to rotate, controls the electromagnet 16 to rotate, and the electromagnet stirs the construction waste. During the stirring process, the electromagnet is in an energized state, and can adsorb magnetic metals onto the electromagnet 16, and can also turn over the construction waste, so as to recover more magnetic metals in the construction waste, and the rotation of the electromagnet 16 can break up the crushed materials in the construction waste, avoid the adhesion of the construction waste after crushing, and prevent the formation of large particles.
[0022] Furthermore, the pre-crushing mechanism described in this embodiment includes two second cylinders 9, which are fixedly mounted on the inner walls of both sides of the box body 1, and the second cylinders 9 are located above the horizontal plate 3. The opposite ends of the moving ends of the two second cylinders 9 are fixedly mounted with moving plates 10, and the opposite surfaces of the two moving plates 10 are fixedly mounted with a plurality of tips. When a large piece of construction waste falls onto the top surface of the horizontal plate 3, the two second cylinders 9 extend to push the two moving plates 10 to move relative to each other, and the tips on the moving plates 10 contact the construction waste. Through the action of the two moving plates 10 and the tips, the large piece of construction waste is split into small pieces of construction waste, and the construction waste with a diameter smaller than the through hole falls downward from the through hole, and the two moving plates 10 continue to split the construction waste if it does not fall from the through hole.
[0023] Furthermore, the crushing mechanism described in this embodiment includes a long groove 11 respectively opened at the front and rear ends of the box body 1, the long groove 11 is located above the support plate, a screw 12 with a motor is movably installed in the long groove 11, a moving block is slidably installed in the long groove 11, a screw hole is opened on one side of the moving block, the screw 12 passes through the screw hole, and a crushing roller 13 is movably installed between the two moving blocks. The motor of the screw 12 is fixedly installed on the inner wall of one side of the long groove 11, and the crushing roller 13 is equipped with a motor. The two motors work synchronously, control the two screws 12 to rotate synchronously, make the two moving blocks move synchronously, and drive the crushing roller 13 to move horizontally back and forth, and the crushing roller 13 crushes the construction waste on the support plate, crushes the construction waste into smaller pieces, and reduces the volume of the construction waste.
[0024] Furthermore, the bottom end of the support plate 4 described in this embodiment is provided with a slide groove 14, a slider is slidably installed in the slide groove 14, and an inclined third cylinder 15 is fixedly installed on the inner wall of the other side of the box body 1, and the top of the moving end of the third cylinder 15 is movably connected with the bottom end of the slider. The third cylinder 15 extends or contracts to make the slider move in the slide groove 14, control the support plate 4 to flip around the hinge point with the box body 1 as the center, and control the downward flow of construction waste.
[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
