[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0041] Example 1

[0042] See also Figures 1 to 8, a structural diagram of a construction waste recycling device for construction provided in Example 1 of the present invention, the construction waste recycling device for construction comprises: a main body 10, a feed hopper 101 is installed at the top opening position of the main body 10; a first discharge port 102 is arranged at the bottom of the feed hopper 101, and a second discharge port 103 is arranged on the side wall of the main body 10.

[0043] A crushing roller assembly 20 is arranged inside the main body 10, and the crushing roller assembly 20 includes a first crushing roller 201 and a second crushing roller 202. The first crushing roller 201 is fixedly sleeved on the second rotating shaft 204, and both sides of the second rotating shaft 204 are arranged through the side walls of the main body 10, and both ends are rotatably installed on the adjacent side walls of the main body 10; the second crushing roller 202 is fixedly sleeved on the first rotating shaft 203, and both sides of the first rotating shaft 203 are arranged through the side walls of the main body 10, and both ends are rotatably installed on the adjacent side walls of the main body 10, and a synchronization component is arranged between the first crushing roller 201 and the second crushing roller 202.

[0044] A power mechanism 30 for driving the crushing roller assembly 20 to rotate comprises a support seat 312 and a drive motor 301 mounted on the support seat 312, wherein the output end of the drive motor 301 is connected to a drive shaft 304, and the drive shaft 304 is rotatably arranged inside the second rotating shaft 204; the drive shaft 304 is transmission-connected to the second rotating shaft 204, and the drive shaft 304 extends along the length direction of the second rotating shaft 204 and passes through both ends of the second rotating shaft 204.

[0045] The screening assembly 50 is arranged inside the main body 10, and the screening assembly 50 includes a screen 501, which is inclined and arranged below the crushing roller assembly 20; both sides of the screen 501 are connected to sliding rods 502, and the sliding rods 502 are horizontally elastically slidably installed on the main body 10.

[0046] In some embodiments, a transmission mechanism 40 is disposed between the driving shaft 304 and the sliding rod 502 , and the transmission mechanism 40 is configured to drive the sliding rod 502 to drive the screen 501 to slide back and forth left and right.

[0047] When in use, the construction waste to be crushed enters the main body 10 through the feed hopper 101, and at the same time, the driving motor 301 drives the driving shaft 304 to drive 201 to rotate, and the second crushing roller 202 also rotates with the cooperation of the synchronization component. In this way, the garbage passes through the two coordinated first crushing rollers 201 and the second crushing rollers 202, and is squeezed and crushed. After the crushing, the garbage is screened through the screen 501. During the screening process, the transmission mechanism 40 is driven by the driving shaft 304 to drive the screen 501 to slide back and forth to improve the screening effect, and the left and right reciprocating sliding frequency of the screen 501 can be coordinated with the rotation speed of the first crushing roller 201 and the second crushing roller 202, so that it can be well adapted to ensure the stability of the equipment operation.

[0048] The driving shaft 304 extends along the length direction of the second rotating shaft 204 and passes through both ends of the second rotating shaft 204 .

[0049] In some embodiments, the first discharge port 102 is used to discharge sand and gravel that have not passed through the screen 501. The second discharge port 103 is used to discharge sand and gravel that have passed through the screen 501.

[0050] In some embodiments, the slide bar 502 is arranged on the outside of the main body 10, and the two sides of the slide bar 502 are respectively horizontally slidably mounted on the adjacent mounting seats 503, and the mounting seats 503 are fixedly mounted on the side wall of the main body 10. The slide bar 502 is sleeved with a fourth elastic member 504 on the outside, and the two ends of the fourth elastic member 504 are respectively fixedly mounted on the slide bar 502 and the adjacent mounting seats 503, so that the slide bar 502 is elastically slidably mounted on the main body 10. The end of the slide bar 502 can be arranged through the through hole on the fourth elastic member 504. The fourth elastic member 504 can be a coil spring.

[0051] In some embodiments, the sliding rod 502 can be connected to the side wall of the screen 501 through a connecting rod, and the connecting rod passes through a through hole on the side wall of the main body 10.

[0052] In some embodiments, the transmission mechanism 40 includes two discs 401, which are distributed on both sides of the main body 10, and the two discs 401 are both sleeved on the driving shaft 304; a plurality of U-shaped blocks 402 are arranged in a circular array on the side wall of the disc 401, and a cylinder 403 is arranged inside the U-shaped block 402. A mounting disc 407 is also arranged on the corresponding side of the disc 401, and the mounting disc 407 is rotatably mounted on the side wall of the main body 10. A matching rod 404 and an incomplete gear 405 are respectively installed on both sides of the mounting disc 407, and the upper end of the matching rod 404 is used to be inserted into the adjacent U-shaped block 402, and one side of the matching rod 404 abuts against the cylinder 403; the incomplete gear 405 is meshed with a rack 406 fixedly mounted on the sliding rod 502. In this way, when the disc 401 rotates with the driving shaft 304, the cylinder 403 drives the matching rod 404 to drive the installation disc 407 to rotate, the installation disc 407 drives the incomplete gear 405 to rotate, and the incomplete gear 405 drives the rack 406 to drive the slide bar 502 to slide to one side. During the rotation of the disc 401, when the cylinder 403 and the matching rod 404 are out of contact, the slide bar 502 returns to the initial state under the action of elasticity, and the slide bar 502 restores the installation disc 407, the rack 406 and the incomplete gear 405 to the initial state through the rack 406. In this way, the screen 501 is driven to slide back and forth.

[0053] In some embodiments, the U-shaped block 402 is a strip-shaped structure.

[0054] like Figure 8 As shown, in some embodiments, the two ends of the cylinder 403 are elastically slidably set in two strip-shaped slide grooves 408 on the inner side wall of the U-shaped block 402, and the distance between the first end of the slide groove 408 and the center of the disk 401 is smaller than the distance between the second end of the slide groove 408 and the center of the disk 401, and the matching rod 404 abuts against one side of the adjacent cylinder 403, and the side faces the first end of the slide groove 408.

[0055] In some embodiments, when the U-shaped block 402 rotates with the disc 401, the matching rod 404 prevents the cylinder 403 in the conflicting U-shaped block 402 from rotating with the U-shaped block 402, and the cylinder 403 drives the conflicting matching rod 404 to rotate. Due to the different weights of the sand and gravel to be screened stored on the screen 501, the sliding rod 502 is subjected to different resistances during the sliding process. The matching rod 404 generates different resistances on the cylinder 403. When the weight of the sand and gravel on the screen 501 increases, the cylinder 403 slides toward the second end. At this time, the cylinder 403 is away from the center of the disc 401, and the overlapping distance between the matching rod 404 and the cylinder 403 increases, thereby increasing the angle at which the cylinder 403 drives the matching rod 404 to swing, and increasing the left and right swinging range of the sliding rod 502, thereby accelerating the screening efficiency. In this way, the screening efficiency can be automatically adjusted according to needs.

[0056] like Figure 8 As shown, in some embodiments, both ends of the cylinder 403 are rotatably sleeved with mounting plates 407, each mounting plate 407 is slidably disposed in an adjacent slide groove 408, and a third elastic member 409 is further connected to the mounting plate 407, and the third elastic member 409 is arranged along the length direction of the slide groove 408, and the third elastic member 409 is fixedly mounted on the top side wall of the slide groove 408 away from the mounting plate 407, so that the mounting plate 407 is elastically slidably mounted in the U-shaped block 402. The third elastic member 409 may be a coil spring.

[0057] Since if the sand and gravel piled on the screen 501 exceeds the set amount, effective screening cannot be achieved even if the swing amplitude of the screen 501 is increased, the disc 401 is elastically rotatably installed on the drive shaft 304, and two transmission discs 306 are sleeved on the drive shaft 304. The transmission disc 306 is elastically slidably arranged along the axial direction of the drive shaft 304. The two drive shafts 304 are respectively arranged at the two ends of the two second rotating shafts 204, and the drive shaft 304 is symmetrically provided with a transmission rod 309 near the end of the second rotating shaft 204. The second rotating shaft 204 is arrayed with no less than two transmission protrusions 305, and one side of the transmission rod 309 abuts against the side wall of the adjacent transmission protrusion 305; two driving bent rods 307 are symmetrically installed on one side of the disc 401 near the transmission disc 306, and the driving bent rod 307 is arranged in a matching groove 308 near one end of the transmission disc 306, and the matching groove 308 is arranged on the side of the transmission disc 306 near the transmission rod 309; the side wall of one side of the matching groove 308 is inclined.

[0058] Specifically, when the weight stored on the screen 501 exceeds the set threshold, the cylinder 403 cannot drive the matching rod 404 to rotate. At this time, the disc 401 deflects relative to the drive shaft 304, and the driving bent rod 307 slides along the inclined side wall of the matching groove 308, so that the transmission disc 306 approaches the disc 401, so that the transmission rod 309 is out of contact with the transmission protrusion 305, so that the drive shaft 304 cannot drive the second rotating shaft 204 to rotate, so that the first crushing roller 201 and the second crushing roller 202 temporarily stop rotating and crushing, and stop feeding the screen 501 for a period of time. When the feeding of the screen 501 is reduced, the disc 401 returns to its initial state under the action of elasticity, and the transmission disc 306 approaches the transmission protrusion 305, so that the transmission rod 309 cooperates with the transmission protrusion 305 again, and the transmission protrusion 305 drives the second rotating shaft 204 to rotate again.

[0059] It should be noted that the disk 401 is rotatably sleeved on the drive shaft 304 and cannot slide along the drive shaft 304. The transmission disk 306 can slide axially along the drive shaft 304 and cannot rotate around the drive shaft 304.

[0060] In some embodiments, a first elastic member 310 is sleeved on the outer side of the driving shaft 304 , and two ends of the first elastic member 310 are respectively fixedly mounted on the driving shaft 304 and the disc 401 , thereby achieving elastic rotation of the disc 401 on the driving shaft 304 .

[0061] In some embodiments, a second elastic member 311 is sleeved on the outer side of the driving shaft 304, and the two ends of the second elastic member 311 are respectively fixedly mounted on the driving shaft 304 and the transmission plate 306, so that the transmission plate 306 can slide elastically along the axial direction of the driving shaft 304. The first elastic member 310 is a torsion spring, and the second elastic member 311 is a coil spring.

[0062] In some embodiments, the driving motor 301 is fixedly mounted on the support base 312 .

[0063] The working principle of the present invention is:

[0064] The construction waste to be crushed enters the main body 10 through the feed hopper 101, and at the same time, the driving motor 301 drives the driving shaft 304 to drive the transmission disc 306 and the transmission rod 309 to rotate. The transmission rod 309 drives the second rotating shaft 204 to drive the first crushing roller 201 to rotate through the transmission protrusion 305. With the cooperation of the synchronization component, the second crushing roller 202 also rotates. In this way, the garbage passes through the two matched first crushing rollers 201 and the second crushing rollers 202, and is squeezed and crushed. The crushed garbage is screened through the screen 501. During the screening process, the disc 401 rotates with the driving shaft 304, and the cylinder 403 in the U-shaped block 402 drives the mounting disc 407 and the incomplete gear 405 through the matching rod 404 to drive the slide bar 502 to slide back and forth to improve the screening effect, and the left and right reciprocating sliding frequency of the screen 501 can be coordinated with the rotation speed of the first crushing roller 201 and the second crushing roller 202, so that it can be well adapted to ensure the stability of the equipment operation. When the weight of sand and gravel on the screen 501 increases, the cylinder 403 slides toward the second end. At this time, the cylinder 403 is away from the center of the disk 401, and the overlapping distance between the matching rod 404 and the cylinder 403 increases, which increases the angle at which the cylinder 403 drives the matching rod 404 to swing, and increases the left and right swing range of the sliding rod 502, thereby accelerating the screening efficiency. In this way, the screening efficiency can be automatically adjusted according to needs. When the weight stored on the screen 501 exceeds the set threshold, the cylinder 403 cannot drive the matching rod 404 to rotate. At this time, the disc 401 deflects relative to the drive shaft 304, and the driving bent rod 307 slides along the inclined side wall of the matching groove 308, so that the transmission disc 306 approaches the disc 401, so that the transmission rod 309 is out of contact with the transmission protrusion 305, so that the drive shaft 304 cannot drive the second rotating shaft 204 to rotate, so that the first crushing roller 201 and the second crushing roller 202 temporarily stop rotating and crushing, and stop feeding the screen 501 for a period of time. When the feeding of the screen 501 is reduced, the disc 401 returns to its initial state under the action of elasticity, and the transmission disc 306 approaches the transmission protrusion 305, so that the transmission rod 309 cooperates with the transmission protrusion 305 again, and the transmission protrusion 305 drives the second rotating shaft 204 to rotate again.
