Description

Technical Field

[0001] This invention relates to the technical field of construction solid waste treatment, specifically to an integrated crushing and screening machine for construction waste. Background Technology

[0002] Construction solid waste, as the name suggests, refers to solid waste in the field of building materials generated during various construction activities such as new construction, building renovation and building demolition. Common construction solid waste mainly includes waste concrete blocks and waste bricks and tiles. In order to achieve effective management and resource utilization of construction solid waste and reduce environmental pollution caused by construction solid waste landfill, construction solid waste such as waste concrete blocks and waste bricks and tiles are usually processed by crushing and screening. These construction solid wastes are then processed into new building materials such as recycled aggregates and recycled environmentally friendly bricks, so as to recycle and reuse construction solid waste.

[0003] A search of the invention patent with authorization announcement number CN109158152B reveals a fine crushing and screening device for construction solid waste, comprising a crushing box, a screening box, a movable grinding roller, a fixed grinding roller, a screening belt, a fine material output belt, and a coarse material pusher plate. The lower end of the material inlet in the crushing box is fixedly connected to and communicates with the screening box. The two ends of the movable grinding roller are slidably connected to the inner sides of two grooved slides. The front and rear ends of the fixed grinding roller are rotatably connected to the inner sides of two circular insertion holes. The screening box includes a box body, a coarse material outlet, a fine material outlet, a belt groove, and an output cross plate. The middle end of the screening belt is slidably connected to the inner side of the belt groove. The middle end of the fine material output belt is slidably connected to the inner sides of the two fine material outlets. The coarse material pusher plate includes an electric push rod, a movable connecting plate, and an L-shaped pusher plate. The vertical plate of the L-shaped pusher plate is slidably connected to the screening belt.

[0004] Based on the aforementioned patents and in conjunction with existing solutions and actual production and processing applications, the current integrated crushing and screening machine for construction waste still has some problems, such as: 1. In the above patent, after the construction solid waste enters the crushing box, it is crushed by the cooperation of the movable grinding roller and the fixed grinding roller. The crushed construction solid waste falls directly into the screening box and is screened by the screening belt. The screening method after crushing in the above patent is the same as the existing crushing and screening machine screening method. The construction solid waste is directly fed into the screening mechanism after crushing. It is impossible to achieve intermittent quantitative feeding when the construction solid waste is connected to the screening mechanism after crushing. This method of directly feeding after crushing is easy to cause the screening mechanism to be overloaded, resulting in accumulation and blockage, which leads to a decrease in screening efficiency. 2. In the above-mentioned patent, for construction solid waste that has not passed the screening, it is pushed to the output plate by the coarse material pusher for temporary storage. However, it cannot meet the requirement of automatically returning the construction solid waste that has not passed the screening to the crushing mechanism for recycling and crushing, which affects the convenience of use.

[0005] Therefore, we propose an integrated crushing and screening machine for construction waste solid waste to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide an integrated crushing and screening machine for construction waste solid waste, in order to solve the problems mentioned in the background art, such as the inability to achieve intermittent quantitative feeding when the crushed construction waste is connected to the screening mechanism, which affects the screening efficiency, and the inability to automatically return the construction waste that has not passed the screening to the crushing mechanism for recycling and crushing, which affects the ease of use.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an integrated crushing and screening machine for construction waste solid waste, comprising: The machine frame has a crushing mechanism fixedly mounted on its upper end; Also includes: A quantitative feeding rack is provided with a feeding pipe on its upper side, and a temporary storage box is connected between the feeding pipe and the discharge port of the crushing mechanism. An arc-shaped partition for sealing the feeding pipe is slidably connected inside the rack cavity of the quantitative feeding rack to provide intermittent quantitative supply of crushed construction solid waste in the temporary storage box. The tube frame has a discharge pipe on its lower side. The tube frame and the screening cylinder inside it are rotated by a flipping mechanism. The tube frame has an inlet pipe connected to the screening cylinder on its right side. The inlet pipe forms a sliding structure in the cavity of the quantitative feeding frame. The quantitatively supplied construction solid waste is shaken and screened by the screening cylinder. The screened construction solid waste is discharged through the discharge pipe. The screw conveyor is fixed to the machine frame. The inlet pipe of the screw conveyor is connected to the waste discharge pipe set on the lower side of the quantitative feeding frame, and the outlet pipe of the screw conveyor is connected to the feed port in the crushing mechanism. It is used to perform cyclic crushing treatment on construction solid waste that has not passed the screening.

[0008] Preferably, the crushing mechanism includes a crushing box fixed to the upper end of the machine frame, a first toothed roller rotatably connected to the right chamber of the crushing box, and a second toothed roller rotatably connected to the left chamber of the crushing box. A first motor for driving is installed at the front end of the central shaft of the first toothed roller and the rear end of the central shaft of the second toothed roller, and the first motor is fixedly connected to the box wall of the crushing box. The toothed blocks in the first toothed roller and the toothed blocks in the second toothed roller are arranged in a staggered state, and the rotation directions of the first toothed roller and the second toothed roller are opposite.

[0009] Preferably, the lower opening of the crushing box is connected and fixedly connected to the upper opening of the temporary storage box, and the lower opening of the temporary storage box is connected and fixedly connected to the feeding pipe. The specifications and dimensions of the cavity in the feeding pipe and the cavity in the waste discharge pipe are the same as the specifications and dimensions of the cavity in the feed pipe. The arc-shaped guide plate and the arc-shaped partition in the feed pipe are connected by a pressing and pushing method, and an arc-shaped spring is installed at the sliding connection between the arc-shaped partition and the quantitative feeder.

[0010] Preferably, the quantitative feeder is arranged in an arc shape, with its arc center coinciding with the flip center of the tube shell frame, and the quantitative feeder is fixed to the bottom of the crushing box by an assembly plate.

[0011] Preferably, the flipping mechanism is arranged symmetrically about the horizontal central axis of the tube frame. The flipping mechanism includes a support frame integrally set on the machine frame, an active rack set in the frame cavity of the support frame, and a driven gear fixed to the central column of the tube frame. The active rack is driven by a hydraulic cylinder fixed to the support frame to form a sliding structure in the support frame. The active rack and the driven gear are meshed together.

[0012] Preferably, a connecting tube shell is rotatably connected inside the shell cavity of the tube shell frame, and the middle part of the connecting tube shell is provided with a discharge port corresponding to and communicating with the unloading pipe at an equal angle. The closed end cap of the connecting tube shell is fixedly connected to a gear ring with the same rotation center as the connecting tube shell, and the gear ring is meshed with a gear. The gear is driven by a second motor fixed to the tube shell frame to form a rotating structure on the tube shell frame. The connecting tube shell drives the screening cylinder to form a synchronous rotating structure to perform rolling screening of construction solid waste.

[0013] Preferably, a sealing cover is slidably connected to the left end cavity of the connecting tube shell, and a spring assembly is installed at the sliding connection between the two. An annular cover is slidably connected to the right end cavity of the connecting tube shell, and a spring assembly is also installed at the sliding connection between the two. The sealing cover is fixed to the left end of the screening cylinder, and the right end of the screening cylinder is fixedly connected to the annular cover. The sealing cover, the annular cover, and the screening cylinder constitute a synchronous sliding structure, which vibrates and screens the construction solid waste during rolling screening.

[0014] Preferably, both the closed cover and the annular cover are fixedly connected with pins, and the pins are slidably connected to the wave ring fixed in the tube frame. The distance between the crests and troughs of the wave ring is equal to the maximum distance the pins slide on the connecting tube frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the integrated crushing and screening machine for construction waste and solid waste effectively controls the flow rate per unit time in the screening operation of construction solid waste treatment by intermittent quantitative feeding, avoiding accumulation. The automatic reflux setting meets the needs of cyclic crushing. In addition, the combination of multiple screening methods realizes the large trajectory movement of three-dimensional tumbling of construction solid waste, accelerating screening and stratification. 1. A temporary storage box is set up for the temporary storage of crushed construction solid waste, serving as a buffer unit to resolve the contradiction between the continuous crushing operation of the crushing mechanism and the intermittent quantitative screening operation of the screening cylinder. The tube frame is driven to rotate by a flipping mechanism, and the arc-shaped guide plate in the feed pipe pushes the arc-shaped baffle, so that the arc-shaped baffle is no longer blocking the feed pipe and the feed pipe is connected accordingly, so as to provide intermittent quantitative feeding of construction solid waste. After the feeding is completed, the arc-shaped spring is reset by elastic deformation, so that the arc-shaped baffle returns to its original position and slides to automatically seal the feed pipe. The intermittent quantitative feeding method allows the screening cylinder to have sufficient time to process the current batch of construction solid waste in the screening operation of construction solid waste treatment, controls the flow rate per unit time, avoids accumulation, and improves screening efficiency and quality. Furthermore, the shell frame is driven to flip downwards, and the feed pipe is connected to the waste discharge pipe. The construction solid waste that has not passed the screening is automatically returned to the crushing mechanism by the screw conveyor. The crushing mechanism crushes the construction solid waste that has not passed the screening again. With the automatic return setting, the crushing operation of construction solid waste treatment meets the needs of cyclic crushing and realizes the automatic cleaning of construction solid waste that has not passed the screening in the screening operation of construction solid waste treatment, ensuring the convenience of operation. 2. When the shell frame is driven to rotate, it drives the screening cylinder and the connecting shell to rotate synchronously, performing shaking screening of construction solid waste. The connecting shell is driven to form a rotating structure within the shell frame. When the connecting shell rotates, it drives the screening cylinder to rotate synchronously, performing rolling screening of construction solid waste. During the rotation of the connecting shell, through the sliding cooperation between the pin and the wave ring, and with the elastic deformation and reset assistance of the spring assembly, the screening cylinder follows the rotation and performs reciprocating sliding motion synchronously within the connecting shell. Existing vibration screening of construction solid waste differs from a single screening method. Through the combined use of multiple screening methods, the crushed construction solid waste can undergo three-dimensional tumbling within the screening cylinder. The large trajectory movement can effectively accelerate the screening and stratification of construction solid waste, reduce the risk of screen hole clogging in the screening cylinder, and effectively improve screening efficiency.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: This invention provides a technical solution: an integrated crushing and screening machine for construction waste, which addresses the problem that when crushed construction waste is connected to a screening mechanism, it cannot meet the purpose of intermittent quantitative feeding of crushed construction waste, thus affecting screening efficiency. After the construction waste is crushed by the crushing mechanism 2, the crushed construction waste falls into a temporary storage box 4 for temporary storage. The flipping mechanism 8 drives the tube frame 6 to flip. When the tube frame 6 is driven to flip upward, the feed pipe 602 slides upward within the quantitative feeding frame 3, and the arc-shaped guide plate in the feed pipe 602 pushes the arc-shaped partition 5. After the arc-shaped partition 5 is pushed and slids, it loses its blockage of the feed pipe 301, making the feed pipe 602 and the feed pipe 301 opposite each other. The temporary storage box 4 contains construction solid waste that slides into the screening cylinder 7 through the feeding pipe 301 and the inlet pipe 602. After a certain amount of construction solid waste enters the screening cylinder 7, the tube frame 6 is driven to flip downwards. The elastic deformation of the arc spring 14 resets the tube frame 6, and the arc partition 5 is pushed to reset and slide to re-seal the feeding pipe 301. This allows for intermittent quantitative feeding of construction solid waste. In addition, the flipping mechanism 8 drives the tube frame 6 to perform up-and-down reciprocating flipping motion, so that the sliding range of the inlet pipe 602 in the quantitative feeding frame 3 is controlled between the feeding pipe 301 and the waste discharge pipe 302. The up-and-down flipping tube frame 6 drives the screening cylinder 7 to perform a swaying motion, which shakes and screens the quantitative amount of construction solid waste entering the screening cylinder 7. In addition, to address the issue that unscreened construction solid waste in the screening mechanism cannot be automatically returned to the crushing mechanism 2, thus failing to achieve cyclic crushing and affecting ease of use, the flipping mechanism 8 drives the shell frame 6 to flip. When the shell frame 6 is driven to flip downwards, the feed pipe 602 slides downwards within the quantitative feed frame 3, and the feed pipe 602 is connected to the waste discharge pipe 302. The unscreened construction solid waste in the screening cylinder 7 slides down the feed pipe 602 and the waste discharge pipe 302 into the screw conveyor 9, and is then transported back to the crushing mechanism 2 by the screw conveyor 9. This achieves automatic return of unscreened construction solid waste and realizes cyclic crushing and processing.

[0020] This technical solution: Please refer to Figures 1-6 A construction waste solid waste crushing and screening integrated machine includes a machine frame 1, which has a frame structure with a frame cavity, and a crushing mechanism 2 is fixedly installed at the upper end of the machine frame 1. It also includes: a quantitative feeding frame 3, a shell frame 6, and a screw conveyor 9. The quantitative feeding frame 3 is located directly below the crushing mechanism 2. A feeding pipe 301 is provided on the upper side of the quantitative feeding frame 3, and a temporary storage box 4 is connected between the feeding pipe 301 and the discharge port of the crushing mechanism 2. An arc-shaped baffle 5 for sealing the feeding pipe 301 is slidably connected inside the frame cavity of the quantitative feeding frame 3 to intermittently and quantitatively supply the crushed construction solid waste in the temporary storage box 4. A discharge pipe 601 is provided on the lower side of the shell frame 6. The shell frame 6, together with the screening cylinder 7 located inside it, is rotated by the driving of the rotating mechanism 8. Furthermore, a feed pipe 602 connected to the screening cylinder 7 is provided on the right side of the casing frame 6, and the feed pipe 602 forms a sliding structure in the frame cavity of the quantitative feeding frame 3. The quantitatively supplied construction solid waste is shaken and screened by the screening cylinder 7. The screened construction solid waste is discharged through the discharge pipe 601. The screw conveyor 9 is fixed to the machine frame 1. The inlet pipe of the screw conveyor 9 is connected to the waste discharge pipe 302 located on the lower side of the quantitative feeding frame 3, and the outlet pipe of the screw conveyor 9 is connected to the feed port in the crushing mechanism 2. The construction solid waste that has not passed the screening is subjected to cyclic crushing treatment.

[0021] Specifically, in this technical solution, the construction solid waste is crushed by the crushing mechanism 2, according to... Figure 1 , Figure 2 and Figure 5 As shown, the crushing mechanism 2 is fixedly installed on the upper end of the machine frame 1. The crushing mechanism 2 includes a crushing box 10, a first toothed roller 11, and a second toothed roller 12. After the crushing box 10 is installed, its lower end overlaps and is fixedly connected to the upper end of the machine frame 1 with bolts. Also, the upper side wall of the crushing box 10 is set in an open state in the middle, and the upper opening is the feeding point of the crushing mechanism 2. Construction solid waste such as waste concrete blocks and waste bricks and tiles are filled through the upper opening of the crushing box 10. Since the first toothed roller 11 has an integrated shaft column at its core, with bearings fixedly connected to both ends of the shaft column, and the second toothed roller 12 also has an integrated shaft column at its core, with bearings fixedly connected to both ends of the shaft column, the first toothed roller 11 is movably installed in the right chamber of the crushing box 10 that is compatible with it, with the two ends of the shaft column connected with bearings respectively inserted into the two side walls of the right chamber of the crushing box 10. The second toothed roller 12 is movably installed in the left chamber of the crushing box 10 that is compatible with it, with the two ends of the shaft column connected with bearings respectively inserted into the two side walls of the left chamber of the crushing box 10. Since the front end of the central shaft of the first toothed roller 11 and the rear end of the central shaft of the second toothed roller 12 are both equipped with a first motor 13 for driving, after the first motor 13 in the first toothed roller 11 is installed, it is fixedly installed on the front side wall of the crushing box 10 by bolts, and its output end is inserted into and fixedly connected to the front end of the central shaft of the first toothed roller 11 by bolts. The first motor 13 in the second toothed roller 12 is installed in the same way as the first motor 13 in the first toothed roller 11. When the two first motors 13 are started, they operate in opposite directions, so that the first toothed roller 11 rotates in the right chamber of the crushing box 10 and the second toothed roller 12 rotates in the left chamber of the crushing box 10, and the rotation directions of the first toothed roller 11 and the second toothed roller 12 are set in opposite directions. Since the toothed blocks in the first toothed roller 11 and the toothed blocks in the second toothed roller 12 are set in a misaligned state, the construction solid waste entering the crushing box 10 is crushed by the opposite rotation of the first toothed roller 11 and the second toothed roller 12 in the crushing mechanism 2, and by utilizing the misaligned cooperation between the toothed blocks in the first toothed roller 11 and the toothed blocks in the second toothed roller 12.

[0022] Meanwhile, in the above technical solutions, according to Figure 2 As shown, the lower wall of the crushing box 10 is open in the middle, with the lower opening serving as the discharge port of the crushing mechanism 2. The temporary storage box 4 is a tubular structure with a square-to-round shape, with an open upper opening for feeding and an open lower opening for discharging. After installation, the upper opening of the temporary storage box 4 is connected to the lower opening of the crushing box 10, and the two are fixed together by bolts. The temporary storage box 4 is used for temporary storage of crushed construction solid waste, serving as a buffer unit to resolve the contradiction between the continuous crushing operation of the crushing mechanism 2 and the intermittent quantitative screening operation of the screening cylinder 7. The crushed construction solid waste in the crushing box 10 slides down through the lower opening of the crushing box 10 and falls into the temporary storage box 4 for temporary storage.

[0023] Specifically, in this technical solution, the flipping mechanism 8 drives the tube frame 6 to perform a flipping motion, according to... Figure 1 , Figure 3and Figure 6 As shown, the flipping mechanism 8 is symmetrically arranged about the horizontal central axis of the tube frame 6. The flipping mechanism 8 includes a support frame 15, a drive rack 16 and a driven gear 17. The support frame 15 is vertically arranged on the machine frame 1 with an integrated structure and has a hollow structure with a frame cavity. The tube frame 6 has an integrated shaft column in the middle of the front shell wall and the middle of the rear shell wall. The axis of the front and rear shaft columns corresponds to the flipping center of the tube frame 6. Bearings are fixedly connected to the front and rear shaft columns. After the tube frame 6 is placed at the arc center of the quantitative feeding rack 3, the front and rear shaft columns of the tube frame 6 correspond to the front and rear flipping mechanisms 8 respectively. After the tube frame 6 is placed, the two shaft columns, along with the bearings, are inserted into the upper ends of the two support frames 15, so that the tube frame 6 is positioned between the two support frames 15 in a movable state. Since the driven gear 17 is mounted and sleeved and fixedly connected to the central shaft of the tube frame 6 by bolts, and since the tube frame 6 forms a rotating structure on the support frame 15 through its central shaft, the driven gear 17 and the central shaft of the tube frame 6 form a synchronous rotating structure. Because the cross-section of the active rack 16 is convex, it is movably inserted into the cavity of the support frame 15 after installation, so that the active rack 16 is positioned in a movable state within the support frame 15. The hydraulic cylinder 18 is placed within the cavity of the support frame 15 and is fixed to the cavity wall of the support frame 15 by bolts. Its output end is inserted into and fixedly connected to the active rack 16 by bolts. Since the active rack 16 is meshed with the driven gear 17, the hydraulic cylinder 18 is activated to extend and retract. Driven by the hydraulic cylinder 18, the active rack 16 slides upwards or downwards within the cavity of the support frame 15. When the active rack 16 slides, the meshing action between the active rack 16 and the driven gear 17 drives the driven gear 17 to rotate synchronously, thus driving the tube frame 6 to perform downward or upward flipping movements.

[0024] Specifically, in this technical solution, intermittent quantitative supply of construction solid waste is carried out in the temporary storage bin 4, according to... Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, a temporary storage box 4 is connected between the feed pipe 301 and the discharge port of the crushing mechanism 2. Since the feed pipe 301 is an integrated structure installed on the upper side wall of the quantitative feed rack 3, its cavity is connected to the cavity of the quantitative feed rack 3. After the temporary storage box 4 is installed, its lower end is connected to the feed pipe 301 and the two are fixed together by bolts. The construction solid waste temporarily stored in the temporary storage box 4 is filled into the cavity of the feed pipe 301. Since the quantitative feeder 3 is installed in the frame cavity of the machine body frame 1, an assembly plate for fixed connection between the quantitative feeder 3 and the crushing box 10 is provided on the left side of the quantitative feeder 3. The lower end of the assembly plate is fixedly connected to the left side of the quantitative feeder 3 by bolts, and the upper end of the assembly plate is fixedly connected to the left side of the crushing box 10 by bolts. Similarly, an assembly plate for fixed connection between the quantitative feeder 3 and the conveying cylinder in the screw conveyor 9 is provided on the right side of the quantitative feeder 3. The left end of the assembly plate is fixedly connected to the right side of the quantitative feeder 3 by bolts, and the right end of the assembly plate is integrated into the lower section of the conveying cylinder in the screw conveyor 9, so that the quantitative feeder 3 is fixedly connected to the crushing box 10 directly below by the assembly plate, so that the quantitative feeder 3 is fixedly placed in the frame cavity of the machine body frame 1. Because the quantitative feeding rack 3 has an arc-shaped structure, its arc center coincides with the flipping center of the tube shell rack 6, and its frame body is hollow with an arc-shaped frame cavity, the inner arc wall of the quantitative feeding rack 3 has a through-type sliding groove. Furthermore, because the feed pipe 602 is an integrated structure on the right side shell wall of the tube shell rack 6, its end has an integrated arc-shaped guide plate, the arc center of which coincides with the arc center of the quantitative feeding rack 3. After the tube shell rack 6 is installed, the feed pipe 602 moves through the sliding groove on the inner arc wall of the quantitative feeding rack 3, and the feed pipe 602... 2. The arc-shaped guide plate is movably locked in the arc-shaped cavity of the quantitative feeder 3. Through the meshing action between the driving rack 16 and the driven gear 17, the driving rack 16 is driven to slide downward, which drives the tube frame 6 to rotate upward. When the tube frame 6 drives the feed pipe 602 to move synchronously, the feed pipe 602 and the arc-shaped guide plate slide upward in the cavity of the quantitative feeder 3. The arc-shaped guide plate in the feed pipe 602 is connected to the arc-shaped partition 5 by a pressing and pushing method. After the feed pipe 602 slides, the arc-shaped guide plate pushes the arc-shaped partition 5. Because the center of the arc of the arc-shaped partition 5 coincides with the center of the arc of the quantitative feeder 3, and because the inner arc wall at the upper end of the arc-shaped partition 5 is provided with an integrated limiting protrusion, after the arc-shaped partition 5 is installed, the limiting protrusion along with it is movably locked in the cavity of the quantitative feeder 3, so that the arc-shaped partition 5 is positioned in a movable state within the quantitative feeder 3. After being pushed, the arc-shaped partition 5 slides within the cavity of the quantitative feeder 3. After the arc-shaped partition 5 slides, it loses its blocking effect on the feed pipe 301, and the cavity of the feed pipe 301... The specifications and dimensions are the same as those of the cavity in the feed pipe 602. After the arc-shaped baffle 5 slides, the arc-shaped guide plate in the feed pipe 602 replaces the position of the arc-shaped baffle 5, so that the cavity of the feed pipe 602 is connected to the cavity of the feed pipe 301. The construction solid waste temporarily stored in the temporary storage box 4 slides into the feed pipe 602 through the feed pipe 301. The feed pipe 602 is connected to the screening cylinder 7 located inside the pipe shell frame 6. The construction solid waste then slides into the screening cylinder 7 through the feed pipe 602. Because an arc-shaped spring 14 is installed at the sliding connection between the arc-shaped partition 5 and the quantitative feeder 3, the arc-shaped spring 14 is set at equal intervals on the arc-shaped partition 5. After the arc-shaped spring 14 is installed, it is movably inserted into the cavity of the quantitative feeder 3. One end of the spring 14 presses against the arc-shaped partition 5, and the other end presses against the cavity wall of the quantitative feeder 3. After the arc-shaped partition 5 is pushed and slid, the arc-shaped spring 14 is squeezed and undergoes elastic deformation. When a fixed amount of construction solid waste enters the screening cylinder 7, it drives the active rack 16 to slide upward, causing the shell frame 6 to rotate downward. The shell frame 6 drives the feed pipe 602 to move synchronously, causing the feed pipe 602, along with its arc-shaped guide plate, to slide downward within the cavity of the quantitative feed frame 3. This causes the arc-shaped guide plate in the feed pipe 602 to lose its pushing effect on the arc-shaped partition 5. The arc-shaped spring 14 is used to reset the arc-shaped partition 5 within the cavity of the quantitative feed frame 3, and the arc-shaped partition 5 re-seals the feed pipe 301. This completes the intermittent quantitative feeding of construction solid waste temporarily stored in the temporary storage box 4 into the screening cylinder 7, thus completing the intermittent quantitative supply of construction solid waste when the crushing mechanism 2 is connected to the screening cylinder 7.

[0025] Meanwhile, in the above technical solutions, according to Figure 2 and Figure 4 As shown, rollers are rotatably connected to the front, back, top, and bottom corners of the arc-shaped partition 5. After the arc-shaped partition 5 is connected to the quantitative feeding rack 3, the rollers are in close contact with the rack cavity wall of the quantitative feeding rack 3. With the assistance of the rollers, the arc-shaped partition 5 can slide smoothly in the rack cavity of the quantitative feeding rack 3. Also, rollers are rotatably connected to the front, back, top, and bottom corners of the arc-shaped guide plate in the feed pipe 602. After the feed pipe 602 is connected to the quantitative feeding rack 3, the rollers are in close contact with the rack cavity wall of the quantitative feeding rack 3. With the assistance of the rollers, the arc-shaped guide plate in the feed pipe 602 can slide smoothly in the rack cavity of the quantitative feeding rack 3.

[0026] Meanwhile, in the above technical solutions, according to Figure 2 and Figure 4 As shown, since sealing rings are fixedly engaged at both ends of the arc-shaped partition 5, after the arc-shaped partition 5 is connected to the quantitative feeding rack 3, the sealing rings adhere to the rack cavity wall of the quantitative feeding rack 3. The sealing rings seal the connection between the arc-shaped partition 5 and the quantitative feeding rack 3, thus sealing the feeding pipe 301 and preventing the construction solid waste in the feeding pipe 301 from overflowing into the rack cavity of the quantitative feeding rack 3 when the arc-shaped partition 5 is in the sealed state. Also, since sealing rings are fixedly engaged at both ends of the arc-shaped guide plate in the feed pipe 602, after the feed pipe 602 is connected to the quantitative feeding rack 3, the sealing rings adhere to the rack cavity wall of the quantitative feeding rack 3. The sealing rings seal the connection between the feed pipe 602 and the quantitative feeding rack 3, thus preventing the construction solid waste in the screening cylinder 7 from flowing back into the rack cavity of the quantitative feeding rack 3 through the feed pipe 602 when the feed pipe 602 slides in the rack cavity of the quantitative feeding rack 3.

[0027] Specifically, in this technical solution, a quantitative amount of construction solid waste is subjected to shaking and screening operation through the screening cylinder 7, according to... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, since a waste discharge pipe 302 is provided on the lower side of the quantitative feeding frame 3, the active rack 16 is driven to slide up and down repeatedly through the meshing action between the active rack 16 and the driven gear 17, causing the shell frame 6 and the screening cylinder 7 inside it to perform up and down reciprocating rotation. The sliding range of the feed pipe 602 in the cavity of the quantitative feeding frame 3 is controlled between the feed pipe 301 and the waste discharge pipe 302. That is, when the shell frame 6 is performing the shaking screening movement, the maximum upward rotation distance of the shell frame 6 is lower than the feed pipe 301, at which time the feed pipe 602 is not connected to the feed pipe 301. The maximum downward rotation distance of the shell frame 6 is higher than the waste discharge pipe 302, at which time the feed pipe 602 is connected to the waste discharge pipe 302. When the screening cylinder 7 follows the shell frame 6 to perform the up and down reciprocating rotation movement, the quantitative construction solid waste in the screening cylinder 7 is shaken and screened. Since the unloading pipe 601 is an integrated structure set on the lower shell wall of the pipe frame 6, the construction solid waste screened by the screening cylinder 7 is discharged from the inside of the pipe frame 6 through the unloading pipe 601. Furthermore, since the lower end of the unloading pipe 601 is fixedly connected to a corrugated folded pipe for conveying materials by bolts, the lower end of the corrugated folded pipe can be used to place a collection box for collecting the screened construction solid waste. Through the setting of the corrugated folded pipe, precise material feeding can be carried out even when the pipe frame 6 is in the state of flipping movement.

[0028] Specifically, in this technical solution, the screw conveyor 9 is used to perform a circulating crushing operation on the construction solid waste that has not passed the screening. Figure 1 , Figure 2and Figure 4 As shown, the screw conveyor 9 includes a conveying cylinder, a screw conveyor rod, and a drive motor. Bearings are fixedly clamped at both the upper and lower ends of the screw conveyor rod. After installation, the screw conveyor rod is movably inserted into the conveying cylinder. The upper and lower ends of the screw conveyor rod, along with the bearings, are respectively inserted into the upper and lower cylinder walls of the conveying cylinder. The drive motor is fixedly installed at the upper end of the conveying cylinder by bolts, and the output end of the drive motor is inserted into and fixedly connected to the upper end of the screw conveyor rod by bolts. Because the left side of the upper section of the conveying cylinder of the screw conveyor 9 is provided with an assembly plate for fixed connection between the screw conveyor 9 and the crushing box 10, the left end of the assembly plate is fixedly connected to the right side of the crushing box 10 by bolts, and the right end of the assembly plate is integrally set in the upper section of the conveying cylinder of the screw conveyor 9. Also because the right side of the upper section of the conveying cylinder of the screw conveyor 9 is also provided with an assembly plate for fixed connection between the screw conveyor 9 and the machine frame 1, the upper end of the assembly plate is integrally set in the upper section of the conveying cylinder of the screw conveyor 9, and the lower end of the assembly plate is fixedly connected to the machine frame 1 by bolts, the screw conveyor 9 is fixedly connected to the machine frame 1. Because the waste discharge pipe 302 is an integrated structure set on the lower side wall of the quantitative feeding frame 3, its cavity is connected to the frame cavity of the quantitative feeding frame 3 and it is inclined downward. Through the meshing action between the active rack 16 and the driven gear 17, the active rack 16 is driven to slide upward, and the tube frame 6 makes a downward flipping motion, so that the feed pipe 602, together with its arc-shaped guide plate, slides downward in the frame cavity of the quantitative feeding frame 3, and the cavity of the feed pipe 602 is correspondingly connected to the cavity of the waste discharge pipe 302. The specifications and dimensions of the cavity in the waste discharge pipe 302 are the same as those of the cavity in the feed pipe 602. After the tube frame 6 flips downward, the screening cylinder 7 is set in a downward inclined state. The construction solid waste that has not passed the screening in the screening cylinder 7 slides down into the waste discharge pipe 302 through the feed pipe 602. Because the upper opening of the crushing box 10 is equipped with an integrated connecting pipe, which is connected to the feed inlet of the crushing mechanism 2, and because the lower end of the conveying cylinder of the screw conveyor 9 is equipped with an integrated inlet pipe, which is inclined upwards, after the screw conveyor 9 is installed, the inlet pipe of the conveying cylinder is connected to the waste discharge pipe 302 and the two are fixed together by bolts. Furthermore, because the upper end of the conveying cylinder of the screw conveyor 9 is equipped with an integrated outlet pipe, which is inclined downwards, after the screw conveyor 9 is installed, the outlet pipe of the conveying cylinder is connected to the waste discharge pipe 302. The connecting pipes in the crushing box 10 are connected and fixed together by bolts. The construction solid waste that has not passed the screening in the waste discharge pipe 302 enters the conveying cylinder through the inlet pipe of the conveying cylinder in the screw conveyor 9. The drive motor in the screw conveyor 9 is started, so that the screw conveying rod in the screw conveyor 9 rotates in the conveying cylinder, conveying the construction solid waste that has not passed the screening upward. Through the outlet pipe of the conveying cylinder in the screw conveyor 9 and the connecting pipe in the crushing box 10, it automatically flows back to the feed port of the crushing mechanism 2. The crushing mechanism 2 then performs cyclic crushing treatment on the construction solid waste that has not passed the screening.

[0029] Example 2: Based on Example 1, please refer to the following example of the present invention. Figures 7-11 The technical solution shown addresses the problem that the single screening mechanism in existing integrated crushing and screening machines cannot allow the crushed construction solid waste to move along a large trajectory on the screening mechanism, which easily leads to screen hole blockage and affects the stratification and efficient screening process. By driving the linkage shell 19 to rotate within the shell frame 6, the linkage shell 19 drives the screening cylinder 7 to rotate synchronously, performing rolling screening of the construction solid waste. During the rotation of the linkage shell 19, the sliding cooperation between the pin 26 and the wave ring 27, and the elastic deformation and reset of the spring assembly 24, allow the screening cylinder 7 to reciprocate within the linkage shell 19, simultaneously performing vibration screening during rolling screening.

[0030] Specifically, in this technical solution, the screening cylinder 7 performs a rolling screening operation on the construction solid waste, according to... Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, since the longitudinal section of the closed cover member 23 is provided in a "convex"-shaped structure, which is divided into two parts: a wide portion and a narrow portion, and since the longitudinal section of the annular cover member 25 is provided in a "convex"-shaped structure, which is divided into two parts: a wide portion and a narrow portion. The specification and size of the central annular cavity of the annular cover member 25 are the same as the specification and size at the right cylinder opening of the screening cylinder 7. Furthermore, since both the left and right sides of the screening cylinder 7 are provided with cylinder openings in an open state, after the screening cylinder 7 is installed, the left end thereof is inserted and fixedly connected to the wide portion of the closed cover member 23 through bolts, and the right end thereof is inserted and fixedly connected to the wide portion of the annular cover member 25 through bolts. The left cylinder opening of the screening cylinder 7 is closed by the closed cover member 23. In addition, the central annular cavity of the annular cover member 25 is arranged to communicate correspondingly with the right cylinder opening of the screening cylinder 7, that is, the right cylinder opening of the screening cylinder 7 corresponds to the lumen of the feeding pipe 602; Since the left end of the linked tube housing 19 is clamped and fixedly connected with a closed end cover through bolts, a cylindrical portion concentric with the closed end cover is provided on the right side wall of the closed end cover. Pin members 26 are fixedly connected to both the upper and lower sides of the closed cover member 23. After the closed cover member 23 is installed, the wide portion thereof is movably inserted into the lumen at the left end of the linked tube housing 19, and the narrow portion thereof is movably sleeved on the cylindrical portion of the closed end cover in the linked tube housing 19, and the upper and lower pin members 26 are respectively movably inserted through the upper and lower side housing walls at the left end of the linked tube housing 19, so that the closed cover member 23 is positioned in the lumen at the left end of the linked tube housing 19 in a movable state. And since the right end of the linked tube housing 19 is clamped and fixedly connected with an annular end cover through bolts, pin members 26 are also fixedly connected to both the upper and lower sides of the annular cover member 25. After the annular cover member 25 is installed, the wide portion thereof is movably inserted into the lumen at the right end of the linked tube housing 19, and the narrow portion thereof is movably inserted through the annular cavity of the annular end cover in the linked tube housing 19 and protrudes outward, and the upper and lower pin members 26 are respectively movably inserted through the upper and lower side housing walls at the right end of the linked tube housing 19, so that the annular cover member 25 is positioned in the lumen at the right end of the linked tube housing 19 in a movable state. The closed cover member 23, the screening cylinder 7 and the annular cover member 25 together form a complete screening component. After the closed cover member 23 and the annular cover member 25 are positioned and installed movably, the screening cylinder 7 is positioned in the lumen of the linked tube housing 19 in a movable state; Since an integrally structured shaft post is provided at the center of the gear member 21, a bearing is fixedly clamped on the shaft post. After the gear member 21 is installed, the shaft post together with the bearing is inserted into the left side housing wall of the tube housing frame 6, and since the second motor 22 is fixedly installed on the left side housing wall of the tube housing frame 6 through bolts after being installed, the output end of the second motor 22 is inserted and fixedly connected to the shaft post of the gear member 21 through bolts. When the second motor 22 is started to operate, it drives the gear member 21 to perform rotational movement on the left side housing wall of the tube housing frame 6; Since the gear ring 20 and the gear 21 are meshed together, and since the left side wall of the closed end cap in the connecting tube housing 19 has a circular groove, the gear ring 20 is snapped into the circular groove of the closed end cap in the connecting tube housing 19 after it is installed and fixed by bolts. The two are set at the same rotation center and form a synchronous rotation structure. After the gear 21 is driven to rotate, the connecting tube housing 19 is driven to rotate through the meshing action between the gear 21 and the gear ring 20. Since the left and right sections of the connecting tube shell 19 are fixedly connected with bearings, the connecting tube shell 19 is movably inserted into the shell cavity of the tube shell frame 6 after installation. The left and right sections are respectively connected with bearings and inserted into the shell cavity walls of the left and right sections of the tube shell frame 6. Since the left and right sections of the connecting tube shell 19 are also fixedly connected with limit rings by bolts, the left and right limit rings limit the left and right bearings respectively, so that the connecting tube shell 19 is positioned in a movable state in the tube shell frame 6. When the connecting tube shell 19 is driven, it rotates in the shell cavity of the tube shell frame 6. When the connecting tube shell 19 rotates, it drives the screening cylinder 7, which is positioned in a movable state inside, to form a synchronous rotation structure. The rotating screening cylinder 7 performs rolling screening of the construction solid waste inside. Because the connecting tube shell 19 has a discharge port 1901 at an equal angle in the middle, and because the diameter of the shell cavity in the connecting tube shell 19 gradually increases from the left end to the discharge port 1901, and the diameter of the shell cavity in the connecting tube shell 19 also gradually increases from the right end to the discharge port 1901, the shell cavity wall of the connecting tube shell 19 is set in an inclined state. That is, the construction solid waste after being screened by the screening cylinder 7 enters the shell cavity of the connecting tube shell 19, and is concentrated at the discharge port 1901 through the inclined shell cavity wall. Since the width of the discharge port 1901 is smaller than the width of the unloading pipe 601, and the discharge port 1901 is correspondingly connected to the unloading pipe 601, the screened construction solid waste slides into the unloading pipe 601 through the discharge port 1901 for external discharge.

[0031] Meanwhile, in the above technical solutions, according to Figure 7 and Figure 8 As shown, sealing rings are provided on both the left and right sides of the discharge port 1901. The sealing rings are fixedly clipped onto the shell cavity wall of the tube frame 6, and the sealing rings are sleeved and attached to the outside of the connecting tube shell 19. The connection between the discharge port 1901 and the unloading pipe 601 is sealed by the two sealing rings. The screened construction solid waste slides into the unloading pipe 601 through the sealed discharge port 1901.

[0032] Specifically, in this technical solution, the screening cylinder 7 simultaneously performs vibratory screening during the rolling screening operation, according to... Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, the wave rings 27 are arranged symmetrically about the vertical central axis of the tube frame 6. The two wave rings 27 correspond to the pins 26 on the closed cover 23 and the pins 26 on the annular cover 25, respectively. Since the ends of the pins 26 are hemispherical, the pins 26 in the closed cover 23 are arranged symmetrically about the horizontal central axis of the closed cover 23. When the pins 26 are installed, they are vertical. They are inserted into and fixed to the closed cover 23 by bolts. They also extend outward through the left end of the connecting tube 19, and their hemispherical ends press against the wave rings 27 on the left side. The arrangement of the pins 26 in the closed cover 23 is also related to the pin arrangement. The method is the same as the placement of the pin 26 in the annular cover 25. The hemispherical end of the pin 26 in the annular cover 25 presses against the wave ring 27 located on the right side. After the two wave rings 27 are placed, they are respectively inserted and fixed to the shell cavity walls at the left and right ends of the tube frame 6 by bolts. The center of the wave ring 27 coincides with the rotation center of the connecting tube shell 19. When the connecting tube shell 19 is driven, it drives the complete screening component formed by the combination of the closed cover 23, the screening cylinder 7 and the annular cover 25 to rotate in the tube frame 6, so that the pin 26 in the closed cover 23 and the pin 26 in the annular cover 25 slide on the two wave rings 27 respectively. Since the distance between the crest and trough in the wave ring 27 is equal to the maximum sliding distance of the pin 26 on the connecting tube shell 19, the sliding fit between the wave ring 27 and the pin 26 causes the sealing cover 23 to slide back and forth in the left end cavity of the connecting tube shell 19, and the annular cover 25 to slide back and forth in the right end cavity of the connecting tube shell 19. The sealing cover 23 is fixed to the left end of the screening cylinder 7, and the right end of the screening cylinder 7 is fixed to the annular cover 25. Driven by the sealing cover 23 and the annular cover 25, the sealing cover 23, the annular cover 25 and the screening cylinder 7 form a synchronous sliding structure, so that the screening cylinder 7 performs reciprocating sliding motion in the cavity of the connecting tube shell 19. That is, the screening cylinder 7 performs reciprocating sliding motion synchronously during rotation to form a vibration motion. The vibrating screening cylinder 7 performs vibration screening treatment on the construction solid waste inside. Because a spring assembly 24 is installed at the sliding connection between the sealing cover 23 and the connecting tube shell 19, and a spring assembly 24 is also installed at the sliding connection between the annular cover 25 and the connecting tube shell 19, and because the spring assembly 24 is divided into an inner ring, a spring body, and an outer ring, with the outer ring sleeved outside the inner ring, the spring body being symmetrical about the center of the inner ring and evenly spaced, and the spring body being placed in the gap between the inner and outer rings, with one end of the spring body fixedly connected to the inner ring and the other end fixedly connected to the outer ring, after the spring assembly 24 on the sealing cover 23 is installed, the inner ring is sleeved and fixedly connected to the narrow part of the sealing cover 23 with bolts, and the outer ring is inserted and fixedly connected to the left end cavity wall of the connecting tube shell 19 with bolts. 4. The placement method is the same as that of the spring assembly 24 on the annular cover 25. When the closed cover 23 is driven to slide, displacement occurs between the inner and outer rings of the middle spring assembly 24. One side of the spring body of the middle spring assembly 24 is compressed and undergoes elastic deformation, while the other side of the spring body is pulled and undergoes elastic deformation. After the closed cover 23 is driven to slide, the spring body of the middle spring assembly 24 is used to assist in the elastic deformation and reset, thereby driving the closed cover 23 to reset and slide. The working method of the spring assembly 24 in the annular cover 25 is the same as that of the spring assembly 24 in the closed cover 23. Thus, with the assistance of the elastic deformation of the spring assembly 24, and in conjunction with the sliding between the pin 26 and the wave ring 27, the complete screening component formed by the combination of the closed cover 23, the screening cylinder 7, and the annular cover 25 vibrates.

[0033] Meanwhile, in the above technical solutions, according to Figure 7 and Figure 8 As shown, since there is a sliding gap between the closed cover 23 and the connecting tube shell 19 that allows the closed cover 23 to move, and there is also a sliding gap between the narrow part of the closed cover 23 and the cylindrical part of the closed end cover in the connecting tube shell 19 that allows the closed cover 23 to move, and since the sliding gap between the closed cover 23 and the connecting tube shell 19 and the sliding gap between the narrow part of the closed cover 23 and the cylindrical part of the closed end cover in the connecting tube shell 19 are both adapted to the amplitude distance of the screening cylinder 7; Because a sliding gap is reserved between the annular cover 25 and the connecting tube shell 19 to allow the annular cover 25 to move, and a sliding gap is also reserved between the narrow part of the annular cover 25 and the annular end cap of the connecting tube shell 19 to allow the annular cover 25 to move, and because the sliding gaps reserved between the annular cover 25 and the connecting tube shell 19 and the narrow part of the annular cover 25 and the annular end cap of the connecting tube shell 19 are both adapted to the amplitude distance of the screening cylinder 7, an effective sliding space is provided for the closing cover 23 and the annular cover 25, ensuring that the screening cylinder 7 can follow the closing cover 23 and the annular cover 25 to vibrate within the connecting tube shell 19.

[0034] Meanwhile, in the above technical solutions, according to Figure 7 and Figure 8 As shown, since the diameter of the wide part of the sealing cover 23 is larger than the diameter of the cavity opening at the left end of the connecting tube shell 19, a sealing ring is fixedly snapped onto the wide part of the sealing cover 23. The sealing ring is attached to the cavity wall at the left end of the connecting tube shell 19 to seal the sliding connection between the sealing cover 23 and the connecting tube shell 19. Since the diameter of the wide part of the annular cover 25 is larger than the diameter of the cavity opening at the right end of the connecting tube shell 19, a sealing ring is fixedly snapped onto the wide part of the annular cover 25. The sealing ring is attached to the cavity wall at the right end of the connecting tube shell 19 to seal the sliding connection between the annular cover 25 and the connecting tube shell 19. Because the narrow end of the annular cover 25 is sleeved and fixedly connected with a sealing ring by bolts, and sealing rings are fixedly snapped on both the front and rear sides of the sealing ring, the sealing ring is placed between the annular end cover of the connecting tube shell 19 and the right end cavity wall of the tube shell frame 6. The sealing rings on both sides are respectively attached to the annular end cover of the connecting tube shell 19 and the right end cavity wall of the tube shell frame 6 to perform sealing treatment at the connection between the annular cover 25 and the feed pipe 602.

[0035] Meanwhile, in the above technical solutions, according to Figure 7 and Figure 8 As shown, since the diameter of the annular cavity in the annular cover 25 is smaller than the diameter of the cavity in the feed pipe 602, the distance between the two is matched with the amplitude distance of the screening cylinder 7. That is, during the rotation and vibration of the screening cylinder 7, it can be ensured that one side of the cavity wall in the annular cover 25 is flush with the cavity wall of the feed pipe 602. This does not affect the quantitative supply of construction solid waste, which enters the screening cylinder 7 through the feed pipe 602 and the annular cavity of the annular cover 25. It also does not affect the construction solid waste that has not passed the screening, which is discharged from the screening cylinder 7 through the annular cavity of the annular cover 25 and the feed pipe 602.
