[0002] During the construction of civil engineering projects, various metal components, such as steel pipes and steel bars, are prone to bending and deformation due to long-term external pressure, impact or other construction loads. When steel pipes can no longer be used, they are usually treated as civil construction waste.

It has obvious limitations. First, the processing equipment has poor adaptability and cannot adapt to steel pipes of different sizes, diameters or materials; second, the processing accuracy is low and it cannot completely correct complex curved steel pipes, resulting in a lower recycling rate.

In the absence of clear evidence that the above content has been disclosed on the filing date of this patent application, the above background technology should not be used to evaluate the novelty and creativity of the present application. Summary of the invention

[0005] The present application provides an intelligent processing device for civil construction waste, which can straighten metal components of different diameters in civil construction waste.

[0006] To achieve the above objectives, the present application discloses the following technical solutions:

[0007] An intelligent treatment device for civil engineering construction waste comprises a carrier frame and a straightening mechanism, wherein the straightening mechanism comprises a rotating frame, a rotating assembly, two groups of straightening roller assemblies, a first adjusting assembly, and a driving assembly; the rotating frame is rotatably mounted on the carrier frame through the rotating assembly, the two groups of straightening roller assemblies are relatively arranged in a first direction, the first direction is perpendicular to the rotation axis of the rotating frame, and the two groups of straightening roller assemblies are slidably arranged on the rotating frame in the first direction, the first adjusting assembly is used to adjust the distance between the two groups of straightening roller assemblies in the first direction; the driving assembly is used to drive the rotating frame to rotate.

[0008] In the embodiment of the present application, the rotating frame can be driven to rotate by the driving assembly, driving the two sets of straightening roller assemblies to continuously rotate around the metal components to be treated as waste materials, thereby achieving multi-angle force correction, thereby effectively improving the straightening accuracy of the metal components. In addition, the distance between the two sets of straightening roller assemblies can be flexibly adjusted by the first adjustment assembly, so that metal components of different diameters in civil construction waste can be straightened. In this way, the problem of poor adaptability of straightening equipment using mechanical roller rotation when processing metal components of different specifications and insufficient ability to correct complex bends is effectively solved.

[0009] In some possible embodiments, each straightening roller assembly includes a plurality of straightening rollers, a plurality of mounting seats, and a plurality of mounting plates. The plurality of straightening rollers are arranged in a one-to-one correspondence with the plurality of mounting seats, and the plurality of mounting seats are arranged in a one-to-one correspondence with the plurality of mounting plates. Each straightening roller can be rotatably mounted on its corresponding mounting seat, and each mounting seat is fixedly mounted on its corresponding mounting plate. The plurality of mounting plates are arranged at intervals in a second direction, and the second direction is parallel to the rotation axis of the rotating frame; each mounting plate is slidably arranged on the carrier in the first direction.

[0010] In some possible implementations, the rotating frame includes a first wall plate and a second wall plate arranged opposite to each other in a third direction, and the third direction is perpendicular to the first direction and the second direction;

[0011] The adjustment assembly includes: a first telescopic device, a first connecting plate, a first transmission assembly and a third connecting plate. The first telescopic device is fixedly mounted on the wall surface of the first wall plate away from the second wall plate, and the telescopic direction of the telescopic rod of the first telescopic device is parallel to the first direction; the first connecting plate is fixedly connected to the telescopic rod of the first telescopic device; a plurality of mounting plates of one group of straightening roller assemblies are fixedly connected to the first connecting plate; the first transmission assembly includes a second connecting plate, a first rack, a first gear, a fixed plate, and a second rack. The second connecting plate is fixedly connected to the first connecting plate and extends in a third direction; the first rack is fixedly connected to the second connecting plate, and the first rack extends in the first direction, the first rack is meshed with the first gear, the first gear is rotatably mounted on the fixed plate, the fixed plate is fixedly connected to the rotating frame, the first gear is also meshed with the second rack, and the first rack and the second rack are arranged opposite to each other in the third direction; the second rack is fixedly connected to the third connecting plate, and a plurality of mounting plates of another group of straightening roller assemblies are fixedly connected to the third connecting plate; the third connecting plate is slidably arranged in the first direction on the wall surface of the second wall plate away from the first wall plate.

[0012] In this way, the first telescopic device can be activated to extend its telescopic rod, thereby driving the plurality of mounting plates connected to the first connecting plate to move in the first direction away from the rotating frame. Since the first connecting plate is fixedly connected to the mounting plate of one group of straightening roller assemblies, the entire group of straightening roller assemblies can be moved as a whole in the direction away from the rotating frame under the action of the first telescopic device.

[0013] At the same time, the first connecting plate is also fixedly connected to the first rack through the second connecting plate, so that the first rack can be driven to move in the same direction of the multiple mounting plates connected to the first connecting plate, and the first rack and the second rack are both meshed with the first gear, and the first rack and the second rack are arranged on different sides of the first gear. Therefore, the first gear will rotate with the movement of the first rack, and the rotation of the first gear can drive the second rack meshed with it to move in the opposite direction of the first rack.

[0014] The second rack is fixedly connected to the third connecting plate, and the third connecting plate is fixedly connected to multiple mounting plates of another set of straightening roller assemblies. Therefore, the reverse movement of the second rack will drive the second set of straightening roller assemblies to move synchronously in a direction away from the rotating frame, thereby achieving synchronous and reverse adjustment of the two sets of straightening roller assemblies, thereby expanding the distance between the straightening rollers of the two sets of straightening roller assemblies to straighten metal components of different diameters in civil construction waste.

[0015] In this way, on the one hand, the operation process of the device can be simplified and the adjustment efficiency can be improved; on the other hand, through the precise engagement of the gear transmission system, it can be ensured that the two sets of straightening roller assemblies always maintain symmetry and synchronization during the adjustment process, and no position deviation will occur, thereby ensuring the adjustment accuracy of the device.

[0016] In some possible embodiments, a plurality of first guide holes are provided on the first wall panel, a plurality of second guide holes are provided on the second wall panel, and a plurality of mounting plates fixedly connected to the first connecting plate are slidably arranged on the rotating frame in the first direction by cooperating with a plurality of first guide rods and the plurality of second guide holes; a plurality of mounting plates fixedly connected to the third connecting plate are slidably arranged on the rotating frame in the first direction by cooperating with a plurality of second guide rods and the plurality of first guide holes.

[0017] In this way, while the mounting plate is slidably arranged on the rotating frame in the first direction, a guiding effect can also be provided for the sliding of the mounting plate, ensuring that the mounting plate slides smoothly and accurately in the first direction and preventing it from deflecting during movement.

[0018] In some possible implementations, the third connecting plate is fixedly provided with a first slide rail, the second wall plate is provided with a first slider, and the third connecting plate is slidably provided on the wall surface of the second wall plate away from the first wall plate through the cooperation of the first slide rail and the first slider. In this way, on the one hand, the sliding friction can be reduced, so that the movement of the third connecting plate is more stable and flexible; on the other hand, the cooperation of the slide rail and the slider can increase the contact points between the third connecting plate and the rotating frame, so as to better disperse the various forces generated by the third connecting plate and the components connected thereto during the working process, so that the third connecting plate is subjected to more uniform and stable forces when it moves relative to the rotating frame.

[0019] In some possible implementations, there are two sets of first transmission assemblies, and the two sets of first transmission assemblies are symmetrically arranged about a central axis of the rotating frame parallel to the first direction. In this way, the stability of the entire adjustment structure can be enhanced and the reliability of the device can be improved.

[0020] In some possible implementations, the intelligent processing device for civil construction waste also includes a cutting mechanism, which is arranged at the output port of the straightening mechanism, and includes: a support frame, a second telescopic device, a first sliding plate and a cutting machine, wherein the support frame is fixedly arranged on the carrier frame; the second telescopic device is fixedly mounted on the support frame; the first sliding plate is slidably mounted on the support frame through the cooperation of the second slide rail and the second slider, and the first sliding plate is fixedly connected to the telescopic rod of the second telescopic device; and the cutting machine is fixedly mounted on the first sliding plate. In this way, the first sliding plate can be driven by the second telescopic device to slide along the support frame, so that the cutting machine fixed on the first sliding plate is moved to the target position to cut the straightened metal component.

[0021] In some possible embodiments, the cutting mechanism further includes a support assembly, the support assembly is located between the output port of the straightening mechanism and the cutting blade of the cutting machine, the support assembly includes a third telescopic device and a support plate, the third telescopic device is fixedly arranged on the carrier, the support plate is fixedly connected to the telescopic rod of the third telescopic device, and the support plate is used to support the straightened metal component. In this way, according to actual conditions, the elongation length of the telescopic rod of the third telescopic device can be controlled, and the height of the support plate can be adjusted to provide stable support for the straightened metal component, thereby ensuring the stability of the straightened metal component during the cutting process. In this way, on the one hand, the shaking of the metal component can be avoided, and the cutting accuracy and quality can be improved; on the other hand, the slight bending of the metal component due to the cutting force of the cutting machine can be prevented.

[0022] In some possible embodiments, the cutting mechanism further includes a second adjustment component, the second adjustment component includes a second sliding plate, a first abutment block, a locking member, and a first pressure sensor, the second sliding plate is slidably arranged on the carrier in the second direction through the cooperation of the third slide rail and the third slider, the first abutment block is fixedly connected to the second sliding plate, and the locking member is used to lock the position of the second sliding plate on the carrier; the first pressure sensor is arranged on the surface of the first abutment block facing the rotating frame and facing the output port of the straightening mechanism;

[0023] The cutting mechanism further includes a second abutment block, a second pressure sensor and a third pressure sensor, wherein the second abutment block is fixedly arranged on the carrier and is located directly below the first sliding plate, and the second pressure sensor is arranged on the surface of the second abutment block facing the second sliding plate; the third pressure sensor is arranged on the surface of the support plate facing away from the carrier;

[0024] The intelligent processing device for civil construction waste also includes a controller, which is electrically connected to the first pressure sensor, the second pressure sensor, the third pressure sensor, the second telescopic device, the third telescopic device, and the cutting machine. The controller is used to control the telescopic rod of the third telescopic device to extend when the pressure information collected by the first pressure sensor reaches a first preset threshold value, control the third telescopic device to stop and control the telescopic rod of the second telescopic device to extend and start the cutting machine when the pressure information collected by the third pressure sensor reaches a second preset threshold value, and control the telescopic rod of the second telescopic device to shorten and reset when the pressure information collected by the second pressure sensor reaches a third preset threshold value;

[0025] The intelligent processing device for civil construction waste also includes a blanking assembly, and a blanking port is opened at the sliding area of ​​the supporting frame corresponding to the second sliding plate; the blanking assembly includes a blanking plate, a support column, and a collecting box, the blanking plate is located directly below the blanking port, and the support column is arranged below the blanking plate for supporting the blanking plate; the end of the blanking plate close to the collecting box is lower than the end of the blanking plate away from the collecting box.

[0026] In this way, when in use, the second sliding plate can be adjusted to the desired position on the carrier frame by the cooperation of the third slide rail and the third slider according to the actual length to be cut, and then the adjusted position can be locked by the locking member. Therefore, when the metal component straightened by the straightening mechanism moves toward the direction close to the first abutment block and abuts against the first pressure sensor, it means that the metal component reaches the required shearing length. At this time, the controller will automatically control the extension of the telescopic rod of the third telescopic device to make the support plate rise. When the pressure information collected by the third pressure sensor on the support plate reaches the second preset threshold, it means that the support plate rises to a height that can stably support the metal component. At this time, the controller will control the third telescopic device to stop, start the cutting machine to perform the cutting operation and control the extension of the telescopic rod of the second telescopic device, and move the cutting machine to the cutting position to cut the metal component. During the cutting process, the telescopic rod of the second telescopic device will continue to extend, driving the first sliding plate and the cutting machine to continue to move until the cutting is completed. When the cutting is completed, the first sliding plate will abut against the second pressure sensor on the second abutment block. Therefore, when the pressure information collected by the second pressure sensor reaches the third preset threshold, it means that the cutting task has been completed. At this time, the controller will automatically control the telescopic rod of the second telescopic device to shorten and reset, and restore the cutting machine to its initial position, so as to prepare for the next cutting process and avoid overcutting and damage to the carrier frame.

[0027] The cut waste enters the inclined second sliding plate through the drop opening, and uses gravity to automatically slide the waste into the collection box. In this way, on the one hand, the cutting length can be adjusted quickly and accurately; on the other hand, the automatic cutting and collection operations can be realized, reducing manual intervention, improving work efficiency and cutting accuracy, and reducing the workload of manual cleaning and the labor intensity of construction workers.

[0028] In some possible embodiments, the rotating assembly includes a first hollow connecting shaft, a second hollow connecting shaft, a first seat bearing, and a second seat bearing, and the rotating frame also includes a third wall plate and a fourth wall plate arranged opposite to each other in the second direction, one end of the first hollow connecting shaft is rotatably arranged on the carrier frame through the first seat bearing, the other end of the first hollow connecting shaft is fixedly connected to the third wall plate, and a first through hole connected to the first hollow connecting shaft is provided on the third wall plate; one end of the second hollow connecting shaft is rotatably arranged on the carrier frame through the second seat bearing, the other end of the second hollow connecting shaft is fixedly connected to the fourth wall plate, and a second through hole connected to the second hollow connecting shaft is provided on the third wall plate; each straightening roller is arranged at an angle. The carrier frame is provided with an avoidance opening for avoiding the straightening mechanism.

[0029] The driving assembly includes a driving device, a first synchronous wheel, a synchronous belt, and a second synchronous wheel. The driving device is used to drive the first synchronous wheel to rotate. The first synchronous wheel is connected to the second synchronous wheel through a synchronous belt. The second synchronous wheel is fixedly sleeved on the first hollow connecting shaft.

[0030] In this way, the metal component to be straightened can be inserted into the interior of the rotating frame through the first hollow connecting shaft and the first through hole, and then the first synchronous wheel can be driven to rotate by starting the driving device, and the second synchronous wheel can be driven to rotate by the synchronous belt, thereby driving the first hollow connecting shaft and the rotating frame fixedly connected to the first hollow connecting shaft to rotate, so that the two groups of straightening roller assemblies can perform continuous rotation around the metal component to achieve multi-angle force correction. When the metal component contacts the straightening roller, the surface of the inclined straightening roller applies a force to the surface of the metal component through rotational motion, pushing the metal component to move forward in the second direction. Under the joint action of multiple groups of straightening roller assemblies, the metal component is subjected to uniform traction during the movement, so that the metal component can maintain a continuous and stable forward state during the straightening process, and move out of the rotating frame from the second through hole and the second hollow connecting shaft to wait for shearing.

[0051] Application Overview: During the construction of civil engineering projects, various metal components, such as steel pipes and steel bars, are prone to bending, deformation and other problems due to long-term external pressure, impact or other construction loads. When steel pipes can no longer be used, they are usually treated as civil construction waste. Reasonable and efficient treatment of these discarded steel pipes and steel bars can not only save resources and reduce construction costs, but also reduce the impact of waste accumulation on the construction site environment. For example, discarded steel pipes and steel bars can be reused as temporary supports after being straightened, thereby avoiding waste of resources and reducing construction costs.

[0052] The related equipment used to straighten steel pipes mainly adopts mechanical roller rotation to restore the basic shape of the steel pipe through simple physical straightening. It has obvious limitations.

[0053] To solve the above technical problems, please refer to Figure 1 Combined with Figure 2 The embodiment of the present application provides an intelligent treatment device for civil construction waste, including a carrier frame 1 and a straightening mechanism 2, the straightening mechanism 2 including a rotating frame 21, a rotating assembly 22, two groups of straightening roller assemblies 23, a first adjusting assembly 24, and a driving assembly 25; the rotating frame 21 is rotatably mounted on the carrier frame 1 through the rotating assembly 22, the two groups of straightening roller assemblies 23 are arranged relatively to each other in a first direction, the first direction is perpendicular to the rotation axis of the rotating frame 21, and the two groups of straightening roller assemblies 23 are slidably arranged on the rotating frame 21 in the first direction, the first adjusting assembly 24 is used to adjust the distance between the two groups of straightening roller assemblies 23 in the first direction; the driving assembly 25 is used to drive the rotating frame 21 to rotate.

[0054] In this way, the rotating frame 21 can be driven to rotate by the driving assembly 25, driving the two sets of straightening roller assemblies 23 to continuously rotate around the metal component 6 treated as waste material, realizing multi-angle force correction, thereby effectively improving the straightening accuracy of the metal component 6. In addition, the distance between the two sets of straightening roller assemblies 23 can be flexibly adjusted by the first adjustment assembly 24, so that metal components 6 of different diameters in civil construction waste can be straightened.

The third wall plate 213 is provided with a first through hole 2131 ( Figure 3 One end of the second hollow connecting shaft 222 is rotatably disposed on the carrier frame 1 through a second seat bearing 224, and the other end of the second hollow connecting shaft 222 is fixedly connected to the fourth wall plate 214, and a second through hole 2141 (not shown) communicating with the second hollow connecting shaft 222 is opened on the third wall plate 213 Figure 3 Each straightening roller 231 is tilted. The support frame 1 is provided with an escape opening 11 for avoiding the straightening mechanism 2.

[0057] See also Figure 3Each straightening roller assembly 23 includes a plurality of straightening rollers 231, a plurality of mounting seats 232, and a plurality of mounting plates 233. The plurality of straightening rollers 231 are arranged one-to-one with the plurality of mounting seats 232, and the plurality of mounting seats 232 are arranged one-to-one with the plurality of mounting plates 233.

Each mounting plate 233 is slidably arranged on the carrier 1 in the first direction. The specific number of straightening rollers 231 is determined according to actual needs and is not limited here.

[0058] See also Figure 3 Combined with Figure 4 The driving assembly 25 includes a driving device 251, a first synchronous wheel 252, a synchronous belt 253, and a second synchronous wheel 254. The driving device 251 is used to drive the first synchronous wheel 252 to rotate. Specifically, the driving device 251 is fixedly mounted on the carrier frame 1.

Exemplarily, the driving device 251 can be a motor. Of course, the present application is not limited thereto. In other embodiments, the driving device 251 can also be a pneumatic motor or a hydraulic motor.

[0060] In this way, the metal component 6 to be straightened can be inserted into the interior of the rotating frame 21 through the first hollow connecting shaft 221 and the first through hole 2131, and then the first synchronous wheel 252 can be driven to rotate by starting the driving device 251, and the second synchronous wheel 254 can be driven to rotate by the synchronous belt 253, so as to drive the first hollow connecting shaft 221 and the rotating frame 21 fixedly connected to the first hollow connecting shaft 221 to rotate, so that the two groups of straightening roller assemblies 23 can continuously rotate around the metal component 6 to achieve multi-angle force correction. When the metal component 6 contacts the straightening roller 231, the surface of the inclined straightening roller 231 applies a force to the surface of the metal component 6 through a rotational motion, pushing the metal component 6 to move forward along the second direction. Under the joint action of the multiple groups of straightening roller assemblies 23, the metal component 6 is subjected to a uniform traction force during the movement, so that the metal component 6 can maintain a continuous and stable forward state during the straightening process, and move out of the rotating frame 21 from the second through hole 2141 and the second hollow connecting shaft 222 to wait for shearing.

[0061] It is understandable that in other embodiments, the avoidance opening 11 may not be provided, but the first seat bearing 223 and the second seat bearing 224 may be raised by the base to raise the rotation axis of the rotating frame 21 to achieve avoidance. In addition, the straightening roller 231 may not be tilted, but the metal component 6 may be manually pushed forward to move out of the rotating frame 21 through the second through hole 2141 and the second hollow connecting shaft 222.

The second connecting plate 2431 is fixedly connected to the first connecting plate 242, and in the third The first rack 2432 is fixedly connected to the second connecting plate 2431, and the first rack 2432 extends in the first direction, the first rack 2432 is meshed with the first gear 2433, the first gear 2433 is rotatably mounted on the fixed plate 2434, the fixed plate 2434 is fixedly connected to the rotating frame 21, the first gear 2433 is also meshed with the second rack 2435, and the first rack 2432 and the second rack 2435 are arranged opposite to each other in the third direction; the second rack 2435 is fixedly connected to the third connecting plate 244, and a plurality of mounting plates 233 of another group of straightening roller assemblies 23 are all fixedly connected to the third connecting plate 244; the third connecting plate 244 is slidably arranged on the wall surface of the second wall plate 212 away from the first wall plate 211 in the first direction.

[0063] In this way, the first telescopic device 241 can be activated to extend its telescopic rod, thereby driving the plurality of mounting plates 233 connected to the first connecting plate 242 to move in the first direction away from the rotating frame 21. Since the first connecting plate 242 is fixedly connected to the mounting plates 233 of one group of straightening roller assemblies 23, the entire group of straightening roller assemblies 23 can move as a whole in the direction away from the rotating frame 21 under the action of the first telescopic device 241.

[0064] At the same time, the first connecting plate 242 is also fixedly connected to the first rack 2432 through the second connecting plate 2431, so that the first rack 2432 can be driven to move in the same direction of the multiple mounting plates 233 connected to the first connecting plate 242, and the first rack 2432 and the second rack 2435 are both engaged with the first gear 2433, and the first rack 2432 and the second rack 2435 are arranged on different sides of the first gear 2433. Therefore, the first gear 2433 will rotate with the movement of the first rack 2432, and the rotation of the first gear 2433 can drive the second rack 2435 engaged with it to move in the opposite direction of the first rack 2432.

[0065] The second rack 2435 is fixedly connected to the third connecting plate 244, and the third connecting plate 244 is fixedly connected to the multiple mounting plates 233 of another group of straightening roller assemblies 23. Therefore, the reverse movement of the second rack 2435 will drive the second group of straightening roller assemblies 23 to move synchronously in the direction away from the rotating frame 21, so as to achieve synchronous and reverse adjustment of the two groups of straightening roller assemblies 23, thereby expanding the distance between the straightening rollers 231 of the two groups of straightening roller assemblies 23 to straighten the metal components 6 of different diameters in the civil construction waste. It can be understood that the principle of shortening the distance between the straightening rollers 231 of the two groups of straightening roller assemblies 23 by controlling the telescopic rod of the telescopic device is the same as that of expanding the distance between the straightening rollers 231 of the two groups of straightening roller assemblies 23, and will not be repeated here.

[0066] In this way, on the one hand, the operation process of the device can be simplified and the adjustment efficiency can be improved; on the other hand, through the precise engagement of the gear transmission system, it can be ensured that the two sets of straightening roller assemblies 23 always maintain symmetry and synchronization during the adjustment process, and no position deviation will occur, thereby ensuring the adjustment accuracy of the device.

[0067] For example, in Figure 5 In the illustrated embodiment, there are multiple first telescopic devices 241, and the multiple first telescopic devices 241 are arranged at equal intervals in the length direction of the first connecting plate 242. The number of first telescopic devices 241 can be determined according to actual needs. The accompanying drawings only give an example in which the number of first telescopic devices 241 is 6, which cannot be regarded as a special limitation on the present application. Of course, the present application is not limited to this. In other embodiments, the number of first telescopic devices 241 can also be one, which is arranged at the center position of the first connecting plate 242. It is necessary to explain that the inner radius of the first hollow connecting shaft 221 and the second hollow connecting shaft 222 should be set to be greater than or equal to the maximum straightening radius of the straightening mechanism 2.

[0068] In another exemplary embodiment, the first telescopic device 241 can be an electric cylinder. Of course, the present application is not limited thereto. In other embodiments, the first telescopic device 241 can also be a hydraulic cylinder or a pneumatic cylinder.

[0069] See also Figure 7 Combined with Figure 8 In some embodiments, a plurality of first guide holes 2111 are formed on the first wall plate 211, a plurality of second guide holes 2121 are formed on the second wall plate 212, a plurality of mounting plates 233 fixedly connected to the first connecting plate 242 are slidably arranged on the rotating frame 21 in the first direction by cooperating with the plurality of second guide holes 2121 through a plurality of first guide rods 234; a plurality of mounting plates 233 fixedly connected to the third connecting plate 244 are slidably arranged on the rotating frame 21 in the first direction by cooperating with the plurality of first guide holes 2111 through a plurality of second guide rods 235. In this way, while the mounting plates 233 are slidably arranged on the rotating frame 21 in the first direction, a guiding function can also be provided for the sliding of the mounting plates 233, so as to ensure that the mounting plates 233 slide smoothly and accurately in the first direction and prevent the mounting plates 233 from deflecting during the movement.

[0070] See also Fig. 9 In some embodiments, a first slide rail 2441 is fixedly provided on the third connecting plate 244, a first slider 2442 is provided on the second wall plate 212, and the third connecting plate 244 is slidably provided on the wall surface of the second wall plate 212 away from the first wall plate 211 through the cooperation of the first slide rail 2441 and the first slider 2442. In this way, on the one hand, the sliding friction can be reduced, so that the movement of the third connecting plate 244 is more stable and flexible; on the other hand, the cooperation of the slide rail and the slider can increase the contact points between the third connecting plate 244 and the rotating frame 21, so as to better disperse the various forces generated by the third connecting plate 244 and the components connected thereto during the working process, so that the third connecting plate 244 is subjected to more uniform and stable force when moving relative to the rotating frame 21.

[0071] See also Fig.10 In some embodiments, the number of the first transmission components 243 is two, and the two first transmission components 243 are symmetrically arranged about the central axis of the rotating frame 21 parallel to the first direction. In this way, the stability of the entire adjustment structure can be enhanced and the reliability of the device can be improved.

[0072] See also Fig.11 Combined with Fig.12 In some embodiments, the intelligent treatment device for civil construction waste also includes a cutting mechanism 3, which is arranged at the output port of the straightening mechanism 2. The cutting mechanism 3 includes: a support frame 31, a second telescopic device 32, a first sliding plate 33 and a cutting machine 34. The support frame 31 is fixedly arranged on the carrier frame 1; the second telescopic device 32 is fixedly installed on the support frame 31; the specific structure of the second telescopic device 32 can be designed with reference to the specific structure of the first telescopic device 241, which will not be repeated here.

[0073] The first sliding plate 33 is slidably mounted on the support frame 31 through the cooperation of the second sliding rail 331 and the second sliding block 332. The first sliding plate 33 is fixedly connected to the telescopic rod of the second telescopic device 32. The cutting machine 34 is fixedly mounted on the first sliding plate 33. In this way, the first sliding plate 33 can be driven by the second telescopic device 32 to slide along the support frame 31, so that the cutting machine 34 fixed on the first sliding plate 33 is moved to the target position to cut the straightened metal component 6.

[0074] See also Fig.13 In some embodiments, the cutting mechanism 3 further includes a support assembly 35, which is located between the output port of the straightening mechanism 2 and the cutting blade of the cutting machine 34. The support assembly 35 includes a third telescopic device 351 and a support plate 352. The third telescopic device 351 is fixedly arranged on the carrier 1, and the support plate 352 is fixedly connected to the telescopic rod of the third telescopic device 351. The support plate 352 is used to support the straightened metal component 6. The specific structure of the third telescopic device 351 can be designed with reference to the specific structure of the first telescopic device 241, and will not be repeated here.

[0075] In this way, the extension length of the telescopic rod of the third telescopic device 351 can be controlled according to actual conditions, and the height of the support plate can be adjusted to provide stable support for the straightened metal component 6, thereby ensuring the stability of the straightened metal component 6 during the cutting process. In this way, on the one hand, the shaking of the metal component 6 can be avoided, and the cutting accuracy and quality can be improved; on the other hand, the metal component 6 can be prevented from being slightly bent due to the cutting force of the cutting machine 34.

[0076] See also Fig.11 Combined with Fig.13 and Fig.14In some embodiments, the cutting mechanism 3 further includes a second adjustment component 36, which includes a second sliding plate 361, a first abutting block 362, a locking member, and a first pressure sensor 363. The second sliding plate 361 is slidably arranged on the support frame 1 in the second direction through the cooperation of the third slide rail 3521 and the third slider 3522. The first abutting block 362 is fixedly connected to the second sliding plate 361, and the locking member is used to lock the position of the second sliding plate 361 on the support frame 1; the first pressure sensor 363 is arranged on the surface of the first abutting block 362 facing the rotating frame 21 and facing the output port of the straightening mechanism 2. Exemplarily, the locking member 364 can be a locking bolt, and a threaded through hole matching the locking bolt is opened on the second sliding plate 361. By tightening the locking bolt, the locking bolt is abutted against the surface of the support frame 1, and the position is locked by the friction force generated between the locking bolt and the surface of the support frame 1. It can be understood that the number of the locking bolts and the threaded through holes can be multiple. The plurality of locking bolts are arranged in one-to-one correspondence with the plurality of threaded through holes.

[0077] The cutting mechanism 3 further includes a second abutment block 37, a second pressure sensor 38 and a third pressure sensor 39. The second abutment block 37 is fixedly arranged on the carrier 1 and is located directly below the first sliding plate 33. The second pressure sensor 38 is arranged on the surface of the second abutment block 37 facing the second sliding plate 361; the third pressure sensor 39 is arranged on the surface of the support plate 352 facing away from the carrier 1.

[0078] The intelligent processing device for civil construction waste also includes a controller 4, which is electrically connected to the first pressure sensor 363, the second pressure sensor 38, the third pressure sensor 39, the second telescopic device 32, the third telescopic device 351, and the cutting machine 34. The controller 4 is used to control the extension of the telescopic rod of the third telescopic device 351 when it is analyzed that the pressure information collected by the first pressure sensor 363 reaches the first preset threshold value, control the third telescopic device 351 to stop and control the extension of the telescopic rod of the second telescopic device 32 and start the cutting machine 34 when it is analyzed that the pressure information collected by the third pressure sensor 39 reaches the second preset threshold value, and control the shortening and resetting of the telescopic rod of the second telescopic device 32 when it is analyzed that the pressure information collected by the second pressure sensor 38 reaches the third preset threshold value;

[0079] The intelligent processing device for civil engineering construction waste also includes a blanking assembly 5, and a blanking opening 12 is opened at the sliding area of ​​the carrier frame 1 corresponding to the second sliding plate 361; the blanking assembly 5 includes a blanking plate 51, a support column 52, and a collection box 53. The blanking plate 51 is located directly below the blanking opening 12, and the support column 52 is arranged below the blanking plate 51 to support the blanking plate 51; the end of the blanking plate 51 close to the collection box 53 is lower than the end of the blanking plate 51 away from the collection box 53. Exemplarily, the blanking plate 51 can be U-shaped.

[0080] In this way, when in use, the second sliding plate 361 can be adjusted to the desired position on the carrier 1 by the cooperation of the third slide rail 3521 and the third slider 3522 according to the actual required cutting length, and then the adjusted position can be locked by the locking member 364. Therefore, when the metal component 6 straightened by the straightening mechanism 2 moves toward the direction close to the first abutment block 362 and abuts against the first pressure sensor 363, it means that the metal component 6 reaches the required cutting length. At this time, the controller 4 automatically controls the extension of the telescopic rod of the third telescopic device 351 to make the support plate 352 rise. When the pressure information collected by the third pressure sensor 39 on the support plate 352 reaches the second preset threshold, it means that the support plate 352 rises to a height that can stably support the metal component 6. At this time, the controller 4 controls the third telescopic device 351 to stop, and starts the cutting machine 34 to perform the cutting operation and controls the extension of the telescopic rod of the second telescopic device 32, and moves the cutting machine 34 to the cutting position to cut the metal component 6. During the cutting process, the telescopic rod of the second telescopic device 32 will continue to extend, driving the first sliding plate 33 and the cutting machine 34 to continue to move until the cutting is completed. When the cutting is completed, the first sliding plate 33 will abut against the second pressure sensor 38 on the second abutment block 37. Therefore, when the pressure information collected by the second pressure sensor 38 reaches the third preset threshold, it means that the cutting task has been completed. At this time, the controller 4 will automatically control the telescopic rod of the second telescopic device 32 to shorten and reset, and restore the cutting machine 34 to its initial position, so as to prepare for the next cutting process and avoid overcutting and damage to the carrier 1.

[0081] The cut waste enters the second inclined sliding plate 361 through the material drop opening 12, and uses gravity to automatically slide the waste into the collection box 53. In this way, on the one hand, the cutting length can be adjusted quickly and accurately; on the other hand, the automatic cutting and collection operations can be realized, reducing manual intervention, improving work efficiency and cutting accuracy, reducing the workload of manual cleaning, and reducing the labor intensity of construction personnel.

[0082] In other embodiments, when it is analyzed that the pressure information collected by the second pressure sensor 38 reaches the third preset threshold, the cutting machine 34 may be controlled to stop moving to avoid idling.

[0083] It is understandable that, in order to facilitate user operation, in some embodiments, the controller 4 is also electrically connected to the first telescopic device 241 and the driving device 251 .

[0084] The present invention and its embodiments are described above, and such description is not restrictive. What is shown in the full text is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
