Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0026] Please see Figure 1 , 2 5, 6, In this embodiment of the invention, a construction waste recycling device includes a crushing box 1. Annular fixed frames 201 are provided on both sides inside the crushing box 1. A sliding block 210 is pressed by a wedge-shaped groove 208. The wedges inside the wedge-shaped groove 208 are aligned in the same direction, causing the sliding block 210 to move inwards towards the annular fixed frame 201. A circular plate 2 is fixed to the end of the annular fixed frame 201. A toothed groove 213 is provided on the top of the outer side of the circular plate 2. Arc-shaped plates 209 are provided on both sides inside the annular fixed frame 201. An elliptical crushing roller 214 is rotatably connected inside the arc-shaped plate 209. The elliptical crushing roller 214... A toothed rod 215 is rotatably connected to the middle of one end. The arc plate 209 is pushed by the sliding block 210 to squeeze the concrete column back and forth. When the annular fixed frame 201 rotates left and right, the arc plate 209 drives the elliptical crushing roller 214 and the toothed rod 215 to rotate in a circular motion. The outer side of the arc plate 209 is fixed with the sliding block 210. Arc frames 206 are set at both ends of the bottom of the annular fixed frame 201. The inner end and the first end of the arc frame 206 are both provided with wedge-shaped grooves 208. The bottom of the arc frame 206 is equipped with a hydraulic rod 205. The first end and the end of the outer side of the arc frame 206 are slidably connected with a sliding plate 207.
[0027] The bottom of the sliding plate 207 is fixedly connected to the inside of the crushing box 1. The middle of the bottom of the annular fixed frame 201 is rotatably connected to the fixed slider 202. The fixed slider 202 is connected to the connecting frame 211 on both sides. The toothed rod 215 rotates by meshing with the tooth groove 213. The toothed rod 215 drives the elliptical crushing roller 214 to rotate and hammer the concrete column back and forth to crush the concrete column. The top of the connecting frame 211 is fixedly connected to the top of the inside of the crushing box 1. The fixed plates 203 are fixed at both ends of the fixed slider 202. The rack 215 meshes with the tooth groove 213, and the sliding block 210 extends to the outside of the annular fixed frame 201. The hydraulic rod 205 is controlled to push the arc frame 206 upward, thereby adjusting the height of the arc frame 206. The left and right rotation of the annular fixed frame 201 drives the arc plate 209 and the sliding block 210 to rotate left and right. The sliding block 210 is set inside the wedge-shaped groove 208, and a first gear 303 is fixed at the center of the circular plate 2.
[0028] In this embodiment: the hydraulic rod 205 is controlled to push the arc frame 206 upward, thereby adjusting the height of the arc frame 206. The left and right rotation of the annular fixed frame 201 drives the arc plate 209 and the sliding block 210 to rotate left and right. The sliding block 210 is squeezed by the wedge-shaped groove 208. The wedges inside the wedge-shaped groove 208 are in the same direction, causing the sliding block 210 to move into the annular fixed frame 201. Then, the sliding block 210 pushes the arc plate 209 to squeeze the concrete column back and forth. When the annular fixed frame 201 rotates left and right, the arc plate 209 drives the elliptical crushing roller 214 and the toothed rod 215 to rotate left and right in a circular motion. The toothed rod 215 rotates by meshing with the tooth groove 213. The toothed rod 215 drives the elliptical crushing roller 214 to rotate and hammer the concrete column back and forth, crushing the concrete column. The first motor 104 is started, which drives the second crushing roller 105 through the first chain 106 to perform finer crushing, and then the material is discharged through the discharge port 102.
[0029] Please refer to this carefully. Figure 1 , 34. One end of the first gear 303 is provided with a gear ring plate 3. A semi-ring toothed gear 302 is fixed in the center of the gear ring plate 3. The inner wall of the gear ring plate 3 is provided with a semi-ring toothed groove 301. The first gear 303 meshes with the semi-ring toothed gear 302. The gear ring plate 3 drives the semi-ring toothed groove 301 and the semi-ring toothed gear 302 to rotate. The gear ring plate 3 drives the semi-ring toothed groove 301 to rotate. When the semi-ring toothed groove 301 rotates to a position of 1 / 6, the semi-ring toothed groove 301 will drive the first gear 303 to rotate in the forward direction. One end of the second gear 401 is equipped with a second motor 4. The bottom of the crushing box 1 is equipped with a first motor 104. The output end of the first motor 104 is connected to a first chain 106. The end of the first chain 106 is connected to the first end with a second crushing roller 105. The top of the crushing box 1 is provided with a feed inlet 103. The side of the crushing box 1 is provided with a discharge outlet 102.
[0030] A conveyor belt 101 is provided at the other end of the crushing box 1. The first motor 104 drives the second crushing roller 105 through the first chain 106 to perform finer crushing, and then discharges through the discharge port 102. There are two first crushing rollers 402 at the top of the crushing box 1. The two ends of the two first crushing rollers 402 are respectively provided with second chains 403. The second gear 401 drives the first crushing rollers 402 to crush the outside of the concrete column once and fall into the annular fixed frame 201. The first crushing rollers 402 on both sides drive the toothed ring plates 3 at both ends to rotate in opposite directions through the second chains 403. The end of the second chain 403 is connected to the toothed ring plate 3, and the second gear 401 is fixed at one end of the second chain 403.
[0031] In this embodiment: the second gear 401 drives the first crushing roller 402 to crush the outer side of the concrete column once, and the crushed concrete falls into the annular fixed frame 201. The first crushing rollers 402 on both sides drive the toothed ring plates 3 at both ends to rotate in opposite directions through the second chain 403. The toothed ring plates 3 drive the semi-annular tooth groove 301 and the semi-annular tooth wheel 302 to rotate. The toothed ring plates 3 drive the semi-annular tooth groove 301 to rotate. When the semi-annular tooth groove 301 rotates to 1 / 6 position, it will drive the first gear 303 to rotate forward. When the semi-annular tooth groove 301 rotates to 3 / 6 position, the semi-annular tooth wheel 303 will rotate forward. When the groove 301 stops meshing with the first gear 303, and the semi-ring toothed gear 302 rotates to a 4 / 6 position, the semi-ring toothed gear 302 meshes with the first gear 303 and drives the first gear 303 to reverse. When the semi-ring toothed gear 302 rotates to a 6 / 6 position, the semi-ring toothed gear 302 stops meshing with the first gear 303, thereby driving the circular plate 2 to rotate in both directions. The two circular plates 2 drive the annular fixed frame 201 to move left and right in opposite directions, twisting the internal concrete column. Through shear force, the cross-section of the concrete column material is twisted and deformed along the direction of the external force.
[0032] Working principle: The concrete column is fed into the feed inlet 103 via the conveyor belt 101. The second motor 4 is started, driving the second gear 401 to rotate. The second gear 401 drives the first crushing roller 402 to crush the outer side of the concrete column once, causing it to fall into the annular fixed frame 201. The first crushing rollers 402 on both sides drive the toothed ring plates 3 at both ends to rotate in opposite directions via the second chain 403. The toothed ring plates 3 drive the semi-annular tooth grooves 301 and semi-annular toothed gears 302 to rotate. The toothed ring plates 3 drive the semi-annular tooth grooves 301 to rotate. When the semi-annular tooth grooves 301 rotate 1 / 6 of their position, they will drive the first gear 303 to rotate forward. When the tooth groove 301 rotates to a position of 3 / 6, the semi-ring tooth groove 301 stops meshing with the first gear 303. When the semi-ring tooth wheel 302 rotates to a position of 4 / 6, the semi-ring tooth wheel 302 meshes with the first gear 303 and drives the first gear 303 to reverse. When the semi-ring tooth wheel 302 rotates to a position of 6 / 6, the semi-ring tooth wheel 302 stops meshing with the first gear 303, thereby driving the circular plate 2 to rotate in both directions. The two circular plates 2 drive the annular fixed frame 201 to move left and right in opposite directions, twisting the internal concrete column. Through shear force, the cross-section of the concrete column material is twisted and deformed along the direction of the external force.
[0033] The hydraulic rod 205 is controlled to push the arc frame 206 upward, thereby adjusting the height of the arc frame 206. The left and right rotation of the annular fixed frame 201 drives the arc plate 209 and the sliding block 210 to rotate left and right. The sliding block 210 is squeezed by the wedge-shaped groove 208. The wedges inside the wedge-shaped groove 208 are in the same direction, causing the sliding block 210 to move into the annular fixed frame 201. Then, the sliding block 210 pushes the arc plate 209 to squeeze the concrete column back and forth.
[0034] When the annular fixed frame 201 rotates left and right, it drives the elliptical crushing roller 214 and the toothed rod 215 to rotate circumferentially through the arc plate 209. The toothed rod 215 rotates by meshing with the tooth groove 213, which in turn drives the elliptical crushing roller 214 to rotate and hammer the concrete column back and forth, crushing it. The first motor 104 is started, driving the second crushing roller 105 through the first chain 106 for finer crushing, before the material is discharged through the outlet 102.
[0035] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
