The present invention uses a workbench surface to perform primary crushing of concrete poles through a breaker hammer, so that concrete stones and steel bars are separated. The separated stones enter the crushing and screening device through a conveying mechanism, are crushed again by a crushing mechanism, and are screened by a secondary screening mechanism. Unqualified stones are returned and crushed again through the cooperation of a return elevator and a secondary screening mechanism, and stones that meet the requirements are screened out through a primary screening filter, thereby reducing the amount of stones crushed by the crushing mechanism and reducing energy consumption. At the same time, small stones can be reduced from being squeezed into fine powder again, and dust content can be reduced, thereby realizing the crushing and recycling of concrete poles and producing concrete aggregates that meet the needs. The invention has a high degree of integration and a complete entire processing procedure, and can be directly used for the preparation and use of recycled aggregates.

[0023] 2. The breaker hammer of the present invention adopts an intelligent hydraulic system and an automatic positioning device, which can accurately strike the concrete pole and break it quickly. The transmission mechanism is driven by an intelligent variable frequency motor, which can automatically adjust the transmission speed according to the weight and speed of the material, thereby improving the material transportation efficiency. Through the central control system, mobile phone APP remote control and intelligent fault diagnosis system, comprehensive monitoring and remote operation of the equipment can be achieved, faults can be discovered and resolved in time, and the operating efficiency and stability of the equipment can be improved. At the same time, the operator can flexibly adjust parameters according to different pole characteristics and recycling requirements to achieve personalized recycling plans, and determine whether there is material on the surface of the second sieve filter through machine vision recognition to achieve automatic recycling, reduce manual intervention, improve recycling efficiency and accuracy, improve the intelligent automatic control of the entire device, and improve crushing and recycling efficiency.

[0024] 3. The present application can accurately control the final output particle size of the crushed material by setting feed filters, second screen filters and return filter screens of different sizes to meet the requirements of aggregate particle size in different application scenarios. Whether it is collecting particles below 40mm or collecting particles below 20mm, or simultaneously producing particles of two gradations of 20-40mm and below 20mm, accurate screening can be achieved, thereby improving the quality and applicability of the output aggregate. For materials that do not meet the screening size, the second screen shaft is rotated to use centrifugal force to throw them out to the return material elevator for cyclic crushing until the required size is reached, thereby ensuring the particle uniformity of the final output aggregate. At the same time, the filter size can be flexibly adjusted according to actual needs, and materials of different particle sizes can be collected and utilized separately, thereby avoiding waste of resources and improving the resource utilization rate after the concrete poles are recycled. The equipment can be adjusted according to different production requirements to adapt to different particle size requirements, thereby improving the adaptability of the equipment. Whether it is single-gradation or multi-gradation production, it can be achieved through simple parameter adjustment, thereby reducing the use cost and complexity of the equipment.

The push plate 11 is driven by an electric hydraulic system. The laser rangefinder on the push plate 11 measures the distance from the concrete pole 5 in real time to ensure that the push plate 11 accurately abuts against the end of the pole. The push plate 11 pushes the concrete pole 5 to the bottom of the breaker 12. The breaker 12 adopts an intelligent hydraulic system to automatically adjust the impact force and knocking frequency according to the data of the force sensor and the vibration sensor. The automatic positioning device on the breaker 12 quickly finds the position of the concrete pole 5 on the workbench 1 and knocks it accurately. The concrete pole 5 is knocked repeatedly to separate the concrete stone and the steel bar until the breaker 12 knocks and crushes the entire concrete pole 5; Sp3: Conveying stage: After crushing, the intelligent control system automatically starts the conveying mechanism 2, which is driven by an intelligent variable frequency motor and automatically adjusts the conveying speed according to the data of the speed sensor and the weight sensor. The conveying mechanism 2 transports the crushed concrete stones to the feed port 31 of the shell 3; Sp4: Preliminary screening stage: After the material enters the housing 3 through the feed port 31, it first passes through the primary screening mechanism 33, and the material is preliminarily screened on the feed filter 331. The larger particles of the material are blocked by the baffle 333, and the smaller particles of the material pass through the feed filter 331 and enter the primary screening discharge channel 34. The larger particles enter the crushing mechanism 35 through the vibration of the feed filter 331; Sp5: Crushing and screening stage: The material in the crushing mechanism 35 is driven by the crushing motor 351 to drive the adjusting roller 354 and the fixed roller 355 to rotate, and the material is crushed. The material is further crushed into smaller particles. The particles crushed by the crushing mechanism 35 fall along the bottom surface of the crushing box 356 onto the surface of the second screen 36; Sp6: Second screening stage: The surface of the second screen filter 36 receives the material crushed by the crushing mechanism 35 and the material in the primary screening discharge channel 34. Under the gravity of the material and the rebound of the second spring 372, the second screen filter 36 shakes, and the material is filtered by the second screening; Sp7: Circulation and recovery stage: Use machine vision recognition to determine whether there is material on the surface of the second screen filter 36. If there is, it means that the material size is too large. The second screen shaft 37 rotates to generate centrifugal force to make the material enter the discharge port 41, and then circulate through the return material elevator 4 to make the material enter from the return material port 32. Repeat Sp4-Sp6 until there is no material on the surface of the second screen filter 36, the crushing and recovery of the concrete pole 5 is completed, and the system stops.

[0037] For visual identification content, it further includes the following: Composition of visual recognition system; Image acquisition equipment: an industrial camera is used and installed inside the housing 3 near the second screen filter 36, which can clearly capture the material on the surface of the second screen filter 36; Image processing software: runs in the central control system and is responsible for processing and analyzing the collected images; The operation steps of the visual recognition system are as follows: Sp1: Image acquisition: The industrial camera shoots the surface of the second sieve filter 36 at a certain frame rate to obtain a real-time image; Sp2: Image preprocessing: Denoising: Use filtering algorithm to remove noise in the image and improve image quality; use Gaussian filtering, its mathematical expression is: ; in, represents pixel coordinates, is the standard deviation, Represents the pixel value after filtering, by adjusting The value of can control the intensity of filtering; Enhance contrast: Use contrast enhancement algorithm to highlight the difference between the material and the background in the image. Use histogram equalization algorithm, the basic idea of ​​which is to transform the histogram of the image into a uniform distribution, thereby enhancing the contrast of the image. Sp3: Feature extraction: Edge detection: Use edge detection algorithms to extract the edge features of materials. Through edge detection, the outline of the material can be determined; Shape feature extraction: Extract the shape features of the material, such as area, perimeter, circularity, etc. The area of ​​the material can be obtained by counting the number of pixels in the white area of ​​the binary image, the perimeter can be obtained by counting the number of edge pixels, and the circularity can be defined as: ; in, Indicates area, Indicates the circumference, The closer the value is to 1, the closer the shape is to a circle; Sp4: Material judgment: Based on the extracted features, it is determined whether there is material on the surface of the second screen filter 36 to set an area threshold , when the extracted material area is larger than When the filter screen 36 is clean, it is considered that there is material on the surface of the second screen filter 36; otherwise, it is considered that there is no material on the surface of the second screen filter 36.

[0038] Sp5: Control Decision: If the judgment result is that there is material on the surface of the second screen filter 36, the central control system issues a command to rotate the second screen shaft 37, generating centrifugal force to throw the material into the discharge port 41, and then the material is circulated and crushed through the return material elevator 4. If the judgment result is that there is no material on the surface of the second screen filter 36, the crushing and recovery of the concrete pole 5 is completed and the system stops.

[0039] Through the above-mentioned visual recognition system, the degree of automation is improved. The machine vision recognition technology can automatically determine the material condition on the surface of the second screen filter 36 without manual intervention, thereby improving the degree of automation of the entire recycling system. At the same time, it can accurately determine the material state. Through image processing and feature extraction algorithms, it can accurately determine whether there is material on the surface of the second screen filter 36 and the size of the material, providing a reliable basis for the control decision of the system, timely discovering oversized materials and performing cyclic crushing, ensuring that the final output of aggregate meets the requirements, and improving the recycling efficiency and product quality. Specific embodiment four:

[0041] like Figure 1-6 As shown, according to the contents in the above specific embodiments, the following contents are further disclosed: The breaker 12 is provided with a concrete pole recovery device, and a concrete pole 5 is provided on the surface of the workbench 1. A push plate 11 is provided on one side of the workbench 1 surface and is abutted against the end of the concrete pole 5. The push plate 11 is driven by an electric hydraulic cylinder. The electric hydraulic cylinder is horizontally bolted to one side of the workbench 1, and a movable end is connected to the side of the push plate 11. The movable end is extended and retracted to drive the push plate 11 to move horizontally on the surface of the workbench 1, thereby pushing the concrete pole 5. The workbench 1 is usually placed on a relatively stable ground and fixed by anchor bolts and the like to ensure that no shaking occurs during the working process. A breaker hammer 12 is provided on the other side of the workbench 1 surface. The outside of the breaker hammer 12 is bolted to the surface of the workbench 1 through a bracket. The breaker hammer 12 uses any existing breaker hammer 12 structure for breaking concrete poles 5. The present application uses a structure in which a hydraulic cylinder drives a hammer head for operation. When the breaker hammer 12 is started, an external hydraulic system delivers high-pressure hydraulic oil to the hydraulic cylinder of the breaker hammer 12. The hydraulic oil drives the piston to move forward rapidly, so that the hammer head obtains a huge impact force, and the hammer head hits the concrete pole 5 to break it. After that, the piston returns to its original position rapidly under the action of the hydraulic oil, preparing for the next impact. By repeating this process continuously, the breaker 12 can continuously break the concrete pole 5. The workbench 1 below the breaker 12 is provided with a discharge port in the longitudinal direction, and the discharge port is located at the top of the conveying mechanism 2. A conveying mechanism 2 is arranged between the end of the workbench 1 close to the breaker 12 and the shell 3. The conveying mechanism 2 includes a horizontal transmission section and an inclined transmission section. The horizontal transmission section is located at the bottom of the discharge port, and the inclined transmission section is against the end of the feed port 31. The conveying mechanism 2 is driven by an intelligent variable frequency motor, and generally a spiral conveying method is used for conveying. The conveying mechanism 2 transports the crushed concrete material falling from the discharge port of the workbench 1 to the feed port 31 of the shell 3 to avoid material scattering and ensure the continuity of work. During the conveying process, the conveying speed can be adjusted as needed to adapt to different work requirements. The concrete pole 5 is initially crushed by the push plate 11 and the breaker 12 structure arranged on the surface of the workbench 1, which is convenient for separating the steel bars and concrete, and convenient for the subsequent rapid crushing of concrete stones.

[0042] When crushing materials, anchor bolts are set to fix the shell 3 to ensure that it is stable and reliable during operation and the normal operation of the internal components will not be affected by vibration. A feed port 31 and a return port 32 are respectively provided on both sides of the top surface of the shell 3. A primary screening mechanism 33, a primary screening discharge channel 34 and a secondary screening screen 36 are symmetrically arranged in the vertical direction inside the shell 3. A secondary screening shaft 37 is provided at the vertical position at the bottom of adjacent secondary screening screens 36. A crushing mechanism 35 is provided between adjacent primary screening discharge channels 34. The entire shell 3 is mainly used for primary screening, crushing and secondary screening of materials, and larger materials are recycled through a reflux elevator to ensure that the particle size of the materials discharged from the shell 3 is uniform.

[0043] When performing preliminary filtration, the primary screening mechanism 33 includes a feed filter 331 and a return filter 332, and the feed filter 331 and the return filter 332 are respectively located at the bottom of the feed port 31 and the bottom of the return port 32, and the feed filter 331 and the return filter 332 are symmetrically inclined. The feed filter 331 and the return filter 332 of the primary screening mechanism 33 are symmetrically inclined, which can quickly screen out larger particles of material. The inclined surface design of the primary screening discharge channel 34 allows the material to automatically slide to the second screening filter 36 or the crushing mechanism 35 without the need for additional power transmission, saving energy. A baffle 333 is hingedly provided at the end of the feed filter 331, and a torsion spring is provided at the connection position between the baffle 333 and the feed filter 331. A first spring 334 is provided at the bottom of the feed filter 331, and the bottom end of the first spring 334 is connected to the primary screening discharge channel The inner wall at the bottom of 34 is vertically connected, and the baffle 333 and the torsion spring are used to prevent material splashing, thereby improving the screening effect and safety. The material enters the shell 3 through the feed port 31 and falls on the surface of the feed filter 331 of the primary screening mechanism 33. Because the baffle 333 is tilted upward under the action of the torsion spring, when the stone on the feed filter 331 is large, the baffle 333 will be pressed down by gravity, so that it falls from the feed filter 331 into the crushing mechanism 35, and the smaller particles will leak through the feed filter 331. The baffle 333 is set to prevent the smaller particles from directly rolling into the crushing mechanism 35. The principle of the reflux filter is the same as that of the feed filter 331. By setting the primary screening mechanism 33, large particles of material and small particles of material can be separated, which is convenient for the large particles to be crushed in the next step.

[0044] When the material is crushed, the crushing mechanism 35 is mainly used to crush larger materials to ensure the uniformity of the materials. Since the crushing mechanism 35 includes a crushing motor 351 and a crushing box 356, the outer wall of the crushing box 356 is bolted to the side of the primary screening discharge channel 34 and the side of the shell 3, and the crushing box 356 is located between the primary screening discharge channel 34, and the crushing box 356 is located inside the shell 3, and is mainly used for the installation of the adjusting roller 354, the fixed roller 355 and the crushing motor 351. The crushing box 356 is provided with an adjusting roller 354 and a fixed roller 355. The adjusting roller 354 is located at the crushing The crushing box 356 is located at the center of the crushing box 356, and both ends of the fixed roller 355 are movably connected to the surface of the crushing box 356. One end of the adjusting roller 354 is connected to a push rod 353. The position of the adjusting roller 354 is adjusted by setting the push rod 353. The push rod 353 is extended to drive the adjusting roller 354 to adjust the moving position inside the crushing box 356. Since the adjusting roller 354 and the fixed roller 355 are the same size, and the fixed roller 355 and the adjusting roller 354 are both conical, the distance between the moving roller and the fixed roller 355 can be adjusted by driving the adjusting roller 354 to move the position through the push rod 353. The spacing between the adjusting roller 354 and the fixed roller 355 can be adapted to materials of different sizes, thereby increasing the adaptability of the crushing mechanism 35 to the size of the materials when being crushed. Since a crushing motor 351 is provided at one end of the crushing box 356 away from the push rod 353, the output shaft of the crushing motor 351 is connected with a gear set 352 that meshes with each other, and the gear set 352 is connected to the central axis position of the adjusting roller 354 and the fixed roller 355. The rotation directions of the adjacent fixed rollers 355 and the adjusting roller 354 are opposite. The entire crushing mechanism 35 is provided by the crushing motor 351. Driven by power, the output cycle of the crushing motor 351 drives the adjusting roller 354 to rotate through the gear set 352. At the same time, through the meshing action of the gear set 352, when the gear at the end of the adjusting roller 354 rotates, it drives the meshing gears on both sides to rotate, thereby driving the fixed roller 355 connected to the gear to rotate. The surfaces of the adjusting roller 354 and the fixed roller 355 are both provided with crushing knife groups. The materials will be continuously squeezed and sheared during the crushing process, so that the materials are further crushed into smaller particles, realizing rapid extrusion and crushing of the materials, facilitating the crushing of the stacked materials, and maintaining the uniformity of the materials.

[0045] The material filtered by the primary screening mechanism 33 is guided through the primary screening discharge channel 34, one side of the primary screening discharge channel 34 is against the inside of the shell 3, the top of the primary screening discharge channel 34 is against the edge of the feed filter 331, the bottom of the primary screening discharge channel 34 extends to the top of the secondary filter 36, and the surface where the inner wall of the primary screening discharge channel 34 is connected to the first spring 334 is an inclined surface, so that the material screened by the primary screening mechanism 33 falls onto the surface of the secondary filter 36 through the primary screening discharge channel 34, and the material crushed by the crushing mechanism 35 falls onto the surface of the secondary filter 36 through the bottom of the crushing box 356. The crushing box 356 is a bottomless structure, which is convenient for the rapid falling of the material.

[0046] When the material is used for secondary screening, one end of the second screen filter 36 is connected to a second screen shaft 37, and the second screen filter 36 and the second screen shaft 37 are installed coaxially in the vertical direction. One end of the second screen shaft 37 penetrates the bottom surface of the shell 3 and is connected to a drive motor 38. The drive motor 38 is connected to the second screen shaft 37, and the second screen shaft 37 is driven to rotate by the rotation of the output shaft. Since a support ring 371 is fixed on the outer wall of the second screen shaft 37, a second spring 372 is vertically connected between the support ring 371 and the bottom of the second screen filter 36, a wedge block 362 is bolted to the inner wall of the shell 3, and the wedge blocks 362 are evenly distributed along the circumference of the inside of the shell 3, a pressure block 361 is provided on the bottom surface of the end of the bottom surface of the second screen filter 36 away from the second spring 372, and the bottom surface of the pressure block 361 is against the inclined surface of the wedge block 362. After the material falls on the second screen filter 36, the second screen shaft 37 rotates under the drive of the driving motor 38, causing the second screen filter 36 to vibrate. At the same time, due to the action of the wedge block 362 and the pressure block 361, the second screen filter 36 will also produce up and down movement during the vibration process, thereby improving the screening effect. A return material elevator 4 is provided on the side of the shell 3 close to the return material port 32, and a discharge port 41 is provided on the side of the return material elevator 4 corresponding to the second screen filter 36. The material that meets the requirements passes through the filter holes of the second screen filter 36 and enters the next collection link. The material that does not meet the requirements enters the discharge port 41 through the centrifugal force generated by the rotation of the second screen shaft 37, and then is lifted to the return material port 32 by the return material elevator 4 for secondary screening and filtration, until all the materials are discharged, and the entire concrete pole 5 is crushed and recycled. Specific embodiment five:

[0048] like Figure 1-6 As shown, according to the contents in the above specific embodiments, the following contents are further disclosed: When the material recovery size is controlled, since a first-level discharge valve 373 is provided near the top of the second screen shaft 37, the filter hole diameters of the second screen filter 36, the feed filter 331 and the return filter 332 are 20-40 mm, the final output particle size of the crushed material can be controlled by controlling the size of the feed filter 331, the second screen filter 36 and the return filter 332. When setting the material size, the second screen material that does not meet the screening size is rotated by the second screen shaft 37, and the material is thrown out through the discharge port 41 by centrifugal force. An electric control valve is provided inside the discharge port 41. After opening the electric control valve, the thrown-away material enters the return elevator 4, and re-enters the shell 3 along the return port 32 through the action of the return elevator 4, and is cyclically crushed until there is no material on the surface of the second screen material.

[0049] When collecting particles smaller than 40 mm, the sizes of the feed filter 331, the return filter 332 and the second screen filter 36 are all 40 mm. At this time, the top of the second screen shaft 37 does not penetrate the inside of the shell 3, and the first-level discharge valve 373 is not provided inside. After passing through the second screen filter 36, the entire material is discharged through the space at the bottom of the second screen filter 36. A discharge port is provided at the bottom of the rear shell 3 for discharging the crushed material. At this time, due to the limitation of the filter aperture of 40 mm, the discharged material is within the entire range of less than 40 mm in size. When collecting and using particles below 20 mm, the structure of the size of 40 mm is the same as the above, the feed filter 331 is changed to 40 mm, the return filter 332 is 20 mm, and the size of the second screen filter 36 is 20 mm. After primary screening, crushing, secondary screening and return, the discharge valve is intermittently opened to prevent particles smaller than 40 mm from being thrown into the return elevator 4 in large quantities. The intermittent opening design of the discharge valve prevents materials smaller than a specific size from being thrown into the return elevator 4 in large quantities, reduces unnecessary cyclic crushing, improves the working efficiency and reliability of the equipment, and at the same time, reduces the energy consumption and wear of the equipment, prolongs the service life of the equipment, and finally discharges materials with particles smaller than 20 mm through the discharge port at the bottom of the shell 3, thereby producing first-graded aggregate; For particles of two gradations of 20-40 mm and less than 20 mm, a first-level discharge valve 373 needs to be set inside the second screen shaft 37, and the second screen shaft 37 is penetrated at the top, and a filter with a filter hole of 40 mm is set at the top, and the feed filter 331 is set to 40 mm, the return filter 332 is set to 20 mm, and the second screen filter 36 is set to 20 mm. The discharge valve is intermittently opened to prevent particles with a diameter of less than 40 mm from being thrown into the return elevator 4 in large quantities. The first-level discharge valve 373 is opened. Since the second screen filter 36 is inclined, The stones larger than 20 mm roll out toward the rotating shaft, the stones smaller than 40 mm fall into the primary discharge cavity through the 40 mm filter screen at the top of the second screen rotating shaft 37, and are discharged and collected through the bottom of the second screen rotating shaft 37, and the stones smaller than 20 mm are discharged through the second screen filter screen 36 and the discharge port at the bottom of the shell 3 and are collected, so that the device can produce concrete aggregates with secondary grading, realize the screening of stones with different particle sizes, and improve the use range of the produced aggregates. Through the cooperation of the primary discharge valve 373 and the discharge valve, it is possible to produce aggregates with two gradations.

[0050] Through the above content, the present application can accurately control the final output particle size of the crushed material by setting the feed filter 331, the second screen filter 36 and the return filter 332 of different sizes to meet the requirements of aggregate particle size in different application scenarios. Whether it is collecting particles below 40mm or collecting particles below 20mm, or simultaneously producing particles of two gradations of 20-40mm and below 20mm, accurate screening can be achieved, thereby improving the quality and applicability of the output aggregate. For materials that do not meet the screening size, the second screen shaft 37 is rotated to use centrifugal force to throw them out to the return elevator 4 for cyclic crushing until they reach the required size, thereby ensuring the particle uniformity of the final output aggregate. At the same time, the filter size can be flexibly adjusted according to actual needs, and materials of different particle sizes can be collected and utilized separately, thereby avoiding waste of resources and improving the resource utilization rate of the concrete poles 5 after recycling. For example, when particles below 20mm or 20-40mm are required for a specific project, aggregates of the corresponding gradation can be accurately produced to meet the requirements. According to the needs of different construction projects, the design of cyclic crushing enables the material to be fully crushed to the required size, maximizes the use of the materials in the concrete pole 5, reduces the demand for new raw materials, conforms to the concept of sustainable development, and can produce primary grading, such as particles below 20mm and secondary grading, such as concrete aggregates with particles of 20-40mm and below 20mm, enriching the types of output aggregates and expanding its scope of use in construction projects and other fields. Aggregates of different gradations can be used in different construction links, improving the flexibility and efficiency of engineering construction. By reasonably setting the filter size and the discharge port, and coordinating the use of the primary discharge valve 373 and the discharge valve, effective screening of stones of different particle sizes is achieved, providing more choices for the construction industry and meeting diverse engineering needs. The equipment can be adjusted according to different production requirements to adapt to different particle size requirements, improving the adaptability of the equipment, and whether it is single-gradation or multi-gradation production, it can be achieved through simple parameter adjustment, reducing the cost and complexity of equipment use.

According to the characteristics of the concrete poles (5) to be crushed and the recycling requirements, the operator sets the initial parameters, including crushing force, transmission speed, and screening accuracy, through the central control system or the mobile phone APP remote control system; Sp2: In the crushing and separation stage, the concrete pole (5) to be crushed is placed on the workbench (1). The pressure sensor and position sensor on the workbench (1) monitor the position and pressure of the pole in real time, and the push plate (11) is started. When the pressure sensor detects that the pole is placed stably, the central control system automatically triggers the push plate (11) to start the program. The push plate (11) is driven by an electric hydraulic system. The laser rangefinder on the push plate (11) measures the distance from the concrete pole (5) in real time to ensure that the push plate (11) and the end of the pole are accurately against each other. The push plate (11) pushes the concrete pole (5) to the bottom of the breaker (12). The breaker (12) adopts an intelligent hydraulic system to automatically adjust the impact force and knocking frequency according to the data of the force sensor and the vibration sensor. The automatic positioning device on the breaker (12) quickly finds the position of the concrete pole (5) on the workbench (1) and knocks it accurately. The concrete pole (5) is knocked repeatedly to separate the concrete stone and the steel bar until the breaker (12) knocks and crushes the entire concrete pole (5); Sp3: Conveying stage: After crushing, the intelligent control system automatically starts the conveying mechanism (2). The conveying mechanism (2) is driven by an intelligent variable frequency motor and automatically adjusts the conveying speed according to the data of the speed sensor and the weight sensor. The conveying mechanism (2) transports the crushed concrete stones to the feed port (31) of the shell (3). Sp4: Primary screening stage: After the material enters the housing (3) through the feed inlet (31), it first passes through the primary screening mechanism (33), and the smaller particles of the material enter the primary screening discharge channel (34), while the larger particles enter the crushing mechanism (35); Sp5: Crushing and screening stage: the material is crushed by the crushing mechanism (35) and the particles fall along the bottom surface of the crushing box (356) onto the surface of the second screen (36); Sp6: Second screening stage: The surface of the second screening screen (36) receives the material crushed by the crushing mechanism (35) and the material in the primary screening discharge channel (34) for second screening filtering; Sp7: Circulation and recovery stage: Machine vision is used to determine whether there is material on the surface of the second screen filter (36). If there is material, it means that the material size is too large. The second screen shaft (37) rotates to generate centrifugal force to allow the material to enter the discharge port (41). The material is then circulated through the return elevator (4) to allow the material to enter from the return port (32). Sp4-Sp6 are repeated until there is no material on the surface of the second screen filter (36). The crushing and recovery of the concrete pole (5) is completed and the system stops.
