It is necessary to batch-adjust the recycled aggregate in the large particle size range to make its particle size meet the corresponding requirements.

[0014] Correspondingly, the present invention also provides a method for batch intelligent adjustment of the particle size of recycled aggregates, and its steps are as follows:

[0015] S1. Preliminary rectification and transfer: Add concrete aggregates to the jaw crusher for preliminary crushing and rectification. Then, use an electric trolley to move the transfer box near the jaw crusher. Cooperate with the rotating motor on it to rotate the transfer box so that its first screen is aligned with the discharge port of the jaw crusher. After the aggregates are initially crushed by the jaw crusher and fall into the first screen through the discharge port, control the electric trolley to move the transfer box into the screening and crushing area, and then proceed with the crushing and screening process for secondary rectification.

[0016] S2. Secondary crushing and screening: When the transfer box with the initially crushed aggregates arrives at the screening and crushing area, control the rotating motor on the electric trolley at the bottom of the transfer box to rotate, drive the transfer box to rotate and adjust its direction so that the position of the clamping seat outside the baffle of the closed area of the outer baffle of the transfer box corresponds exactly to the electric gripper on the screening mechanism of the crushing and screening part. Control the screening electric push rod to push the electric gripper close to the clamping seat, and control the electric gripper to clamp the clamping seat. At this time, the two screening mechanisms and the transfer box are integrated into one body. The electric trolley can cooperate with the two screening electric push rods to act, so that the transfer box slides back and forth rapidly on the track in the screening and crushing area to simulate the vibration screening process. First, move the transfer box to the area below the impact crusher head, make its screen located in the closed area on the right side of the transfer box, and correspond to the impact crusher head on it. Then, control the drive motor to drive the impact crusher head to descend and act back and forth to perform secondary rectification on the aggregates in the top screen. The impact crushing and vibration screening processes can be completed alternately. If necessary, such as performing secondary rectification on the aggregates in the second layer of the screen, the top screen can be controlled by the screening electric trolley to move to the hollow area, and then control the crushing electric push rod to lower the impact crusher head mounting seat to an appropriate height, and repeat the above impact crushing process to perform secondary rectification on the aggregates in the second layer of the screen. Similarly, the third layer is also rectified in the same way. After the secondary rectification and screening are completed, the transfer box can be controlled to move to the particle size analysis interface for the particle size analysis process.

[0017] S3. Particle size analysis: When the transfer box comes near the particle size analysis interface, the particle size analysis process can be carried out. The transfer box is rotated by the rotating motor at the bottom of the transfer box to make its hollow part close to the aggregate output unit. At this time, according to the actual detection needs, the layer of screen to be detected is controlled to move to the hollow area through its screening electric trolley, and then the electric trolley on the L-shaped track is controlled to drive the output electric push rod mounting plate on it to move on the vertical track to a height lower than the screen. The output rotating motor at the output end of the output electric push rod mounting plate and the output receiving hopper on it are controlled to make the output receiving hopper insert into the transfer box through the baffle opening of the hollow structure, and the screening rotating motors at both ends of the screen are started to make the screen The net rotates, and the aggregate falls into the output receiving hopper. At this time, the output receiving hopper is retracted and moved to the top of the temporary storage hopper at the end of the L-shaped track. The output rotating motor is controlled to rotate, driving the output receiving hopper to rotate. Part of the aggregate falls into the temporary storage hopper for storage. The excess aggregate can be restored to the output receiving hopper to the top of the L-shaped track, and the output electric push rod is pushed out to cooperate with the output rotating motor to rotate and pour the aggregate back into the screen of the transfer box. After that, the aggregate in the temporary storage hopper can be taken with the assistance of the construction personnel and put into the laser particle size analyzer for analysis. Finally, the average particle size and particle size distribution curve of the aggregate are obtained, and the transfer box moves to the light transmission analysis interface for light transmission analysis process;

[0018] S4, light transmittance analysis: when the transfer box arrives at the light transmittance analysis interface, part of the aggregate is transferred to the temporary storage hopper of the aggregate output unit in the same way as above, and the construction personnel assist in spreading the aggregate on the glass plate. At this time, the laser rangefinder matrix can be started to monitor the height of the aggregate particle bed on the glass plate in real time, and at the same time, the first electric push rod of the scraper and the second electric push rod of the scraper are cooperated to drive the alloy scraper to move back and forth on the glass plate to level it, so that the particle bed height on the glass plate meets the requirements. At this time, the transmittance meter is started to analyze the transmittance of the aggregate particles. Finally, according to the obtained transmittance, average particle size and particle size distribution curve, it is determined whether the particle size range of the secondary rectification aggregate of this batch meets the standard. If it meets the standard, the transfer box can be moved to the compliant output interface for storage. If it does not meet the standard, it will be transported to the non-compliant output interface for storage or the above-mentioned secondary rectification and monitoring process will be repeated on the transfer track to obtain the aggregate particles that have been rectified three times, which will be circulated in sequence until they meet the standard and are stored in the storage box of the compliant storage unit;

[0019] S5. Output storage: After the rectification and testing processes are completed, the aggregates are delivered to the output interface for output. The aggregates are transferred from the screen of the transfer box to the output hopper in the same way as the above-mentioned aggregate output unit, and then transferred from the output hopper to the storage box. Different storage boxes can be circulated on the storage track to store aggregate particles of different sizes. At this point, the batch intelligent control of the particle size of the rectified recycled aggregate is completed.

[0020] As described above, the beneficial effects of the intelligent batch adjustment system and method for the particle size of recycled aggregates of the present invention are as follows:

[0021] 1. The present invention connects various parts of the intelligent regulation of the particle size of recycled aggregates through a transfer track, enabling the initial crushing, secondary crushing and screening rectification, particle size analysis, light transmittance analysis, and aggregate output storage to be completed closely and quickly. It is more intelligent and efficient, suitable for recycling and processing a large number of recycled aggregates, and completing the regulation and rectification operations.

[0022] 2. The transfer part designed in the present invention consists of a dual-region transfer box. This transfer box can not only cooperate with the crushing and screening part to complete secondary rectification, crushing, and screening in the closed area on the right, but also cooperate with the regulation part and the storage part in the hollow area on the left to complete the particle size monitoring and regulation of the aggregates and the output and storage of the aggregates. Multiple groups of transfer parts can be set on a transfer track to work in a cycle, greatly improving the rectification efficiency of the aggregates. At the same time, it is sufficient to handle the simultaneous regulation of a large number of aggregates. Since this structure can be reused, it can ensure the stability of the particle size range of the aggregates produced in the same batch, effectively saving the manpower and material resources consumed by particle size adjustment.

[0023] 3. The present invention makes the transfer box cooperate with the screening and crushing area, the screening mechanism, and the impact crushing mechanism. The transfer box and the two screening mechanisms are integrated and reciprocate on the vertical transfer track to simulate manual screening. At the same time, the impact crushing mechanism is used to alternately perform secondary rectification on the aggregates on the screen mesh, and the number of layers of the screen mesh for specific rectification can be adjusted according to actual needs, greatly improving the rectification and screening efficiency of concrete aggregates, and at the same time improving the rectification fineness to obtain more suitable particle size concrete.

[0024] 4. The aggregate output unit provided in the present invention can cooperate with the hollow structure of the transfer box to separately output, retrieve, and store the aggregates after secondary rectification. The laser particle size analyzer and the light transmittance analysis unit provided near the aggregate output unit can analyze and regulate the aggregates after rectification to obtain the average particle size, particle size distribution curve, and light transmittance of the aggregates, and then determine whether the aggregates of this batch meet the required particle size range. If they meet the standards, they will be output through the compliance output interface on the track. If they do not meet the standards, they can be output through the non-compliance interface, or the above-mentioned secondary rectification and detection processes can be repeated on the circulating track for three or four times of rectification until they meet the standards and are stored in the storage box of the compliance storage unit. This method greatly improves the quality control effect of the particle size of the aggregates after rectification, quickly obtains a large number of high-quality and compliant recycled aggregates, and at the same time has strong adaptability. The aggregates with compliant particle sizes can be stored in the compliance storage box, and those that do not meet the standards can be rectified repeatedly until they meet the standards. Those that really do not meet the standards can be directly stored in the non-compliance storage box for standby, effectively saving the energy consumption of recycled aggregate treatment.

[0046] For the convenience of those of ordinary skill in the art to understand and implement the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and implementation examples. It should be understood that the implementation examples described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0047] Next, in combination with Figures 1 to 7 A regenerated aggregate particle size batch intelligent adjustment system and method provided by the present invention will be introduced in detail.

[0048] As Figure 1 shown, the regenerated aggregate particle size batch intelligent adjustment system of the present invention includes a base part 1000 as an overall base, and a plurality of transfer parts 2000 installed on its transfer track 1004, and also includes a crushing and screening part 3000, a regulation part 4000, and a storage part 5000 that are distributed counterclockwise nearby.

[0049] As Figure 2As shown in the figure, the base part 1000 includes the ground 1001 as the main body, on which there is a crusher base 1002. An jaw crusher 1003 is installed on the crusher base 1002. A transfer track 1004 is provided near the crusher base 1002. The transfer track 1004 is in an inverted concave shape, and there are four interfaces on it. The concave part of the concave shape is the screening and crushing area 1004a. Along the outside of it, there are a particle size analysis interface 1004b, a light transmission analysis interface 1004c, a compliance output interface 1004d, and a non-compliance output interface 1004e distributed counterclockwise. The crusher base 1002 is located at Figure 2 the lower left corner of the transfer track 1004 in Figure 2 . The purpose of setting this structure is that the recycled aggregate that has been initially crushed by the jaw crusher 1003 can be output to the transfer part 2000 on the transfer track 1004, and then the transfer part 2000 can carry the aggregate for subsequent screening and crushing, particle size analysis, and light transmission analysis, and finally store it in the compliance storage unit 5100 or the non-compliance storage unit 5200. Compared with the prior art, the present invention connects all parts of the intelligent regulation of the particle size of the recycled aggregate through a transfer track 1004, enabling the initial crushing, secondary crushing and screening rectification, particle size analysis, light transmission analysis, and aggregate output storage to be completed closely and quickly. It is more intelligent and has higher efficiency, suitable for circularly processing a large number of recycled aggregates and completing the regulation and rectification operations.

[0050] As shown by Figure 3 the figure, the transfer part 2000 is mainly composed of a special transfer box. The transfer box is installed on the transfer track 1004 through an electric trolley. A rotary motor is connected to the electric trolley, and the output shaft of the rotary motor is fixedly connected to the transfer box base 2001 at the bottom end of the transfer box. An outer transfer box baffle 2002 is provided around the upper end of the transfer box base 2001. Inside the outer transfer box baffle 2002, there is a transfer box inner partition 2003 that divides the rectangular area inside the box into two parts. Figure 3On the outer baffle 2002 of the transfer box in a region on the left side, a number of baffle openings 2002a are provided at intervals, making it a hollow structure. In the height region of the outer baffle 2002 of the transfer box where there are no openings, at the corresponding height of the inner partition 2003 of the transfer box, partition openings 2003a are provided at intervals, and the partition openings 2003a connect the left and right regions inside the box. On the front and rear baffles of the outer baffle 2002 of the transfer box and the baffle regions without openings in the left hollow structure, there are baffle inner tracks 2005 that pass through the partition openings 2003a to connect the left and right regions inside the box. Three baffle inner tracks 2005 are provided successively from top to bottom, corresponding to the three baffle openings 2002a from top to bottom. On the baffle inner track 2005, there is a screening electric trolley 2006a. The screening electric trolley 2006a is connected to a screening rotary motor 2006b on the outer side of the baffle, and the output shaft of the screening rotary motor 2006b is connected to a screen 2006c. Structures such as the screening electric trolley 2006a and the screening rotary motor 2006b are all common parts, and the description of screening and the like is only for the distinction of functional uses. The screen 2006c matches the baffle inner track 2005, and there are three in total from top to bottom. At the same time, the diameter of the screen holes decreases successively from top to bottom. On the outer surface of the right region of the outer baffle 2002 of the transfer box, there is a clamping seat 2004.

[0051] The purpose of setting this structure is that when aggregate transfer is required, first, the transfer box is moved to the vicinity of the jaw crusher 1003 by an electric trolley, and the transfer box is rotated by the rotary motor on it so that its first screen 2006c is aligned with the discharge port of the jaw crusher 1003. After the aggregate after the primary crushing by the jaw crusher 1003 falls into the first screen 2006c through the discharge port, the electric trolley is controlled to move the transfer box into the screening and crushing area 1004a. Next, the secondary rectification crushing and screening process is carried out. This process is mainly carried out in the closed area on the right side of the transfer box. After the crushing and screening process is completed, the transfer box comes to the regulation part 4000 and the storage part 5000 in sequence for aggregate particle size analysis and aggregate storage. This process is mainly carried out in the hollow area on the left side of the transfer box. Compared with the prior art, the transfer part 2000 designed in the present invention consists of a double-region transfer box. This transfer box can not only cooperate with the crushing and screening part 3000 to complete secondary rectification, crushing, and screening in the closed area on the right side, but also cooperate with the regulation part 4000 and the storage part 5000 in the hollow area on the left side to complete the particle size monitoring and regulation of the aggregate and the output and storage of the aggregate. Multiple groups of transfer parts 2000 can be set on one transfer track 1004 to work in a cycle, greatly improving the rectification efficiency of the aggregate. At the same time, it is sufficient to cope with the simultaneous regulation of a large number of aggregates. And because this structure can be reused, it can ensure the stability of the particle size range of the aggregates produced in the same batch, effectively saving the manpower and material resources consumed by particle size adjustment.

[0052] by Figure 4As shown in the figure, the crushing and screening section 3000 includes two screening mechanisms that are distributed as the main body near the front and rear ends of the screening and crushing area 1004a. The screening mechanism includes a screening electric push rod mounting base 3001 installed on the ground 1001. A screening electric push rod 3002 facing inwards is provided on the screening electric push rod mounting base 3001. The output end of the screening electric push rod 3002 is connected to an electric gripper 3003. The crushing and screening section 3000 further includes an impact crushing mechanism located at the right end of the screening and crushing area 1004a. The impact crushing mechanism includes a crushing electric push rod 3004 installed on the ground 1001. The output end of the crushing electric push rod 3004 faces vertically upwards, and its output end is connected to an impact crushing head mounting base 3005. A driving motor 3006 is provided at the top end near the end of the impact crushing head mounting base 3005 close to the screening and crushing area 1004a. An impact crushing head 3007 is provided at the bottom end of the driving motor 3006. The driving motor 3006 can drive the impact crushing head 3007 to reciprocate up and down to achieve the function of impact crushing. Here, the screening and crushing area 1004a is a vertical track on the transfer track 1004, that is, the vertical track area in the middle of the concave shape. This vertical track area can be used as the back-and-forth movement track of the transfer box during screening operation. The purpose of setting this structure is that when the transfer box brings the initially crushed aggregate to the screening and crushing area 1004a, at this time, control the rotation motor on the electric trolley at the bottom of the transfer box to rotate, drive the transfer box to rotate and adjust its direction so that the position of the clamping seat 2004 outside the baffle of the closed area of the outer baffle 2002 of the transfer box corresponds exactly to the electric gripper 3003 on the screening mechanism of the crushing and screening section 3000. Control the screening electric push rod 3002 to push out the electric gripper 3003 close to the clamping seat 2004, and control the electric gripper 3003 to clamp the clamping seat 2004. At this time, the two screening mechanisms are integrated with the transfer box. The electric trolley can cooperate with the two screening electric push rods 3002 to act, so that the transfer box slides back and forth rapidly on the track of the screening and crushing area 1004a to simulate the vibration screening process. At this time, first move the transfer box to the area below the impact crushing head 3007, so that the screen 2006c is located in the closed area on the right side of the transfer box and corresponds to the impact crushing head 3007 above it. At this time, control the driving motor 3006 to drive the impact crushing head 3007 to descend and reciprocate to perform secondary rectification on the aggregate in the top layer of the screen 2006c. The impact crushing and vibration screening processes can be completed alternately. If necessary, such as performing secondary rectification on the aggregate in the second-layer screen 2006c, the top-layer screen 2006c can be controlled by the screening electric trolley 2006a to move to the hollow area, and then control the crushing electric push rod 3004 to lower the impact crushing head mounting base 3005 to an appropriate height, and repeat the above impact crushing process to perform secondary rectification on the aggregate in the second-layer screen 2006c. Similarly, the third layer is also rectified secondarily in the same way.It should be noted that the structure of the upper, middle and lower three - layer screen meshes 2006c in the screening box here can be adjusted according to actual needs, such as adjusted to four - layer, five - layer, etc. After the secondary rectification and screening are completed, the transfer box can be controlled to move to the particle size analysis interface 1004b for the particle size analysis process.

[0053] Compared with the prior art, in the present invention, through the cooperation of the designed transfer box with the screening and crushing area 1004a, the screening mechanism, and the impact crushing mechanism, the transfer box and the two screening mechanisms are integrated and reciprocate on the vertical transfer track 1004 to simulate manual screening. At the same time, the impact crushing mechanism is used to alternately perform secondary rectification on the aggregate on the screen mesh 2006c, and the number of layers of the screen mesh for specific rectification can be adjusted according to actual needs, greatly improving the efficiency of concrete aggregate rectification and screening, while improving the rectification fineness to obtain more suitable - sized concrete.

[0054] As Figures 5 - 6 shown, the control part 4000 includes a laser particle size analysis mechanism and a light transmittance analysis mechanism, which are respectively located near the particle size analysis interface 1004b and the light transmittance analysis interface 1004c. The laser particle size analysis mechanism includes a laser particle size analyzer 4001 and an aggregate output unit 4100, and the light transmittance analysis mechanism includes a light transmittance analysis unit 4200 and an aggregate output unit. The structures of the aggregate output units used in the laser particle size analysis mechanism and the light transmittance analysis mechanism are the same. The laser particle size analyzer 4001 is a general - purpose component, which can quickly and accurately measure the size distribution of particles in the aggregate through the principle of laser scattering. It can provide detailed information such as the average size of particles and the particle size distribution curve, helping to understand the size range and dispersion of aggregate particles. The aggregate output unit 4100 is mainly composed of an L - shaped track mounting plate 4101. An L - shaped track 4102 is provided on the inner surface of its vertical plate, and an L - shaped opening 4101a of a reduced proportion is provided beside the L - shaped track 4102. The L - shaped track 4102 is connected to an output electric push rod mounting plate 4103a through an electric trolley. An output electric push rod 4103b is provided at the upper left corner of the output electric push rod mounting plate 4103a. One end of the output electric push rod 4103b extends backward through the L - shaped opening 4101a, and an output rotary motor 4103c is connected to the output end of the other end. The output end of the output rotary motor 4103c is connected to an output receiving hopper 4103d. The L - shaped track mounting plate 4101 is divided into a vertical plate and a flat plate. A rectangular notch is provided near the end of the flat plate close to the L - shaped track 4102, and the internal area of the rectangular notch is used to store a temporary storage hopper 4104.

[0055] The light transmittance analysis unit 4200 is installed on the left side of the temporary storage hopper 4104. It is mainly composed of a light transmittance meter 4201, and a glass plate 4201a is provided on the light transmittance meter 4201. The light transmittance meter 4201 is a general component. It can emit light through a light source. After passing through the sample, part of the light is absorbed and part of the light is transmitted to the detector. The detector measures the intensity of the light passing through the sample, and this intensity is proportional to the light transmittance of the sample. By comparing the intensity of the transmitted light of the sample with the intensity of the reference light without the sample, the light transmittance of the sample can be calculated. Here, it is used to monitor the light transmittance of the aggregate particle size, and then estimate whether the aggregate particle size range meets the requirements; the mechanisms near the light transmittance meter 4201 are divided into four regions: upper, lower, left, and right. It itself occupies the left region, the upper region is the temporary storage hopper 4104, the right region is the scraper mechanism, and the lower region is the bed layer uniformity monitoring mechanism. The scraper mechanism is successively connected from bottom to top by a scraper track mounting seat 4202, a scraper track 4202a, a first scraper electric push rod mounting plate 4203a, a first scraper electric push rod 4203b, and a second scraper electric push rod 4203c. The first scraper electric push rod mounting plate 4203a is installed on the scraper track 4202a through an electric trolley, and the output end of the second scraper electric push rod 4203c is connected with an alloy scraper 4203d. The bed layer uniformity monitoring mechanism is mainly composed of a laser rangefinder mounting seat 4204, and a laser rangefinder matrix 4205 is provided thereon, which is used to detect the uniformity of the aggregate bed layer on the glass plate 4201a to ensure the accuracy of the light transmittance monitoring.

[0056] The purpose of setting this structure is that when the transfer box comes near the particle size analysis interface 1004b, the particle size analysis process can be carried out. The transfer box is rotated by the rotating motor at the bottom of the transfer box so that its hollow part is close to the aggregate output unit 4100. At this time, according to the actual detection needs, control the screen 2006c to be detected to move to the hollow area through its screening electric trolley 2006a. Then, control the electric trolley on the L-shaped track 4102 to drive the output electric push rod mounting plate 4103a thereon to move on the vertical track to a height lower than the screen 2006c. Control the output rotating motor 4103c at the output end of the output electric push rod mounting plate 4103a and the output receiving hopper 4103d thereon, so that the output receiving hopper 4103d is inserted into the transfer box through the baffle opening 2002a of the hollow structure. Start the screening rotating motors 2006b at both ends of the screen 2006c to rotate the screen, and the aggregate falls into the output receiving hopper 4103d. At this time, retract the output receiving hopper 4103d and move it above the temporary storage hopper 4104 at the end of the L-shaped track 4102. Control its output rotating motor 4103c to rotate, drive the output receiving hopper 4103d to rotate, and part of the aggregate falls into the temporary storage hopper 4104 for storage. The excess aggregate can restore the output receiving hopper 4103d to the uppermost end of the L-shaped track 4102, and is pushed out by the output electric push rod 4103b and rotated in cooperation with the output rotating motor 4103c to pour the aggregate back into the screen 2006c of the transfer box. Thereafter, with the assistance of construction workers, the aggregate in the temporary storage hopper 4104 can be taken and placed into the laser particle size analyzer 4001 for analysis, and finally the average particle size and particle size distribution curve of this batch of aggregate can be obtained. The transfer box moves to the light transmittance analysis interface 1004c for the light transmittance analysis process; when the transfer box comes to the light transmittance analysis interface 1004c, part of the aggregate is transferred to the temporary storage hopper 4104 of the aggregate output unit 4100 in the same way as above, and the aggregate is laid on the glass plate 4201a by the assistance of construction workers. At this time, the laser rangefinder matrix 4205 can be started to monitor the height of the aggregate particle bed layer on the glass plate in real time, and at the same time, cooperate with the first electric push rod 4203b and the second electric push rod 4203c of the scraper to drive the alloy scraper 4203d to move back and forth on the glass plate 4201a to scrape and level, so that the height of the particle bed layer on the glass plate 4201a meets the requirements. At this time, start the light transmittance meter 4201 to analyze the light transmittance of the aggregate particles. Finally, according to the obtained light transmittance, average particle size and particle size distribution curve, determine whether the particle size range of this batch of secondary rectified aggregate meets the standard. If it meets the standard, the transfer box can be moved to the compliance output interface 1004d for storage. If it does not meet the standard, it will be transported to the non-compliance output interface 1004e for storage or repeat the above secondary rectification and monitoring processes on the transfer track 1004 to obtain the aggregate particles of the third rectification, and cycle in turn until it is compliant and stored in the storage box 5002 of the compliance storage unit 5100.

[0057] Compared with the prior art, the aggregate output unit 4100 provided in the present invention can cooperate with the hollow structure of the transfer box to separately output, retrieve, and store the aggregates after secondary rectification. The laser particle size analyzer 4001 and the light transmittance analysis unit 4200 provided near the aggregate output unit 4100 can analyze and regulate the rectified aggregates to obtain the average particle size, particle size distribution curve, and light transmittance of the aggregates, so as to determine whether the aggregates of this batch meet the required particle size range. If they meet the standard, they are output through the compliance output interface 1004d on the track. If they do not meet the standard, they can be output through the non-compliance interface 1004e, or the above-mentioned secondary rectification and detection processes are repeated on the circulating track for three or four times of rectification until they meet the standard and are stored in the storage box 5002 of the compliance storage unit 5100. This method greatly improves the quality control effect of the particle size of the rectified aggregates, quickly obtains a large number of high-quality compliant recycled aggregates, and has strong adaptability. The compliant particle sizes can be stored in the compliant storage box, and the non-compliant ones can be rectified repeatedly until they meet the standard. If they really do not meet the standard, they can be directly stored in the non-compliant storage box for standby, effectively saving the energy consumption of recycled aggregate treatment.

[0058] As Figure 7 shown, the storage part 5000 includes a compliance storage unit 5100 and a non-compliance storage unit 5200 near the compliance output interface 1004d and the non-compliance output interface 1004e; both groups of storage units are connected to the output interface through the aggregate output unit 4100, but the temporary storage hopper 4104 is deleted from the aggregate output unit 4100, and instead there is a discharge track 5001. A number of storage boxes 5002 are provided on the discharge track 5001, and the storage box 5002 is installed on the discharge track 5001 through an electric trolley; the purpose of setting this structure is that after the rectification and detection processes are completed, the aggregates come to the output interface for output. In the same way as the aggregate output unit 4100 works above, the aggregates are transferred from the screen 2006c of the transfer box to the output receiving hopper 4103d, and then transferred from the output receiving hopper 4103d to the storage box 5002. Different storage boxes 5002 can move in a cycle on the storage track 5001 to store aggregate particles of different particle sizes.

[0059] The intelligent system for batch - wise intelligent adjustment of the particle size of recycled aggregates in the present invention can first perform preliminary crushing on the aggregates through the jaw crusher 1003 installed on the base part 1000 to obtain the preliminarily rectified particle size. At this time, the particle size still does not meet the requirements, and it is transported to the transfer box in the transfer part and comes to the crushing and screening area 1004a, the particle size analysis structure, and the light transmittance analysis interface 1004c in sequence through the transfer track 1004 for crushing and screening, particle size analysis, and light transmittance analysis. The average particle size, particle size distribution curve, and light transmittance of the recycled concrete after secondary rectification are obtained, and then the distribution interval of the particle size is indirectly obtained. If it meets the requirements, this rectification is completed, and the subsequent aggregates of the same batch can all use the same steps to obtain aggregates with similar compliant particle sizes, and are transported to the compliant storage unit 5100 through the compliant output interface 1004d for storage. If not compliant, they can be transported to the non - compliant storage unit 5200 for storage, or the above - mentioned secondary rectification process can be carried out again to obtain the particle size after the third rectification and perform particle size analysis until the particle size is compliant, realizing the large - batch intelligent control and processing of the particle size of recycled aggregates, greatly saving the manpower and material resources required for adjusting the particle size of concrete aggregates, and improving the efficiency and the quality of the rectified aggregates.

[0060] Correspondingly, the method for batch - wise intelligent adjustment of the particle size of recycled aggregates in the present invention comprises the following steps:

[0061] S1. Preliminary rectification and transfer: Add the concrete aggregates into the jaw crusher 1003 for preliminary crushing and rectification. Then, use the electric trolley to move the transfer box near the jaw crusher 1003, and cooperate with the rotating motor on it to rotate the transfer box so that its first screen 2006c is aligned with the discharge port of the jaw crusher 1003. After the aggregates after the initial crushing by the jaw crusher 1003 fall into the first screen 2006c through the discharge port, control the electric trolley to move the transfer box into the crushing and screening area 1004a, and then carry out the crushing and screening process for secondary rectification.

[0062] S2. Secondary crushing and screening: When the transfer box carrying the aggregates that have completed the primary crushing arrives at the screening and crushing area 1004a, at this time, control the rotation motor on the electric trolley at the bottom of the transfer box to rotate, drive the transfer box to rotate and adjust its direction so that the position of the clamping seat 2004 outside the baffle of the closed area of the outer baffle 2002 of the transfer box corresponds exactly to the electric clamping jaw 3003 on the screening mechanism of the crushing and screening part 3000. Control the screening electric push rod 3002 to push out the electric clamping jaw 3003 to approach the clamping seat 2004, and control the electric clamping jaw 3003 to clamp the clamping seat 2004. At this time, the two screening mechanisms and the transfer box are integrated into one body, and the transfer box can be actuated by the electric trolley in cooperation with the two screening electric push rods 3002 to slide back and forth rapidly on the track in the screening and crushing area 1004a to simulate the vibration screening process. At this time, first move the transfer box to the area below the impact crushing head 3007 so that its screen 2006c is located in the closed area on the right side of the transfer box and corresponds to the impact crushing head 3007 above it. At this time, control the drive motor 3006 to drive the impact crushing head 3007 to descend and act back and forth to perform secondary rectification on the aggregates in the top-layer screen 2006c. The impact crushing and vibration screening processes can be completed alternately. If necessary, such as performing secondary rectification on the aggregates in the second-layer screen 2006c, the top-layer screen 2006c can be controlled by the screening electric trolley 2006a to move to the hollow area, and then control the crushing electric push rod 3004 to lower the impact crushing head mounting seat 3005 to an appropriate height, and repeat the above impact crushing process to perform secondary rectification on the aggregates in the second-layer screen 2006c. Similarly, the third layer is also rectified twice in the same way. It should be noted that the structure of the upper, middle and lower three-layer screens 2006c in the screening box can be adjusted according to actual needs, such as adjusted to four layers, five layers, etc. After the secondary rectification and screening are completed, the transfer box can be controlled to move to the particle size analysis interface 1004b for the particle size analysis process;

[0063] S3. Particle size analysis: When the transfer box comes near the particle size analysis interface 1004b, the particle size analysis process can be carried out. The transfer box is rotated by the rotating motor at the bottom of the transfer box so that its hollow part is close to the aggregate output unit 4100. At this time, according to the actual detection needs, the sieve 2006c to be detected is controlled to move to the hollow area through its screening electric trolley 2006a. Then, the electric trolley on the L-shaped track 4102 drives the output electric push rod mounting plate 4103a thereon to move on the vertical track to a height lower than the sieve 2006c. The output rotating motor 4103c at the output end of the output electric push rod mounting plate 4103a and the output receiving hopper 4103d thereon are controlled so that the output receiving hopper 4103d is inserted into the transfer box through the baffle opening 2002a of the hollow structure. The screening rotating motors 2006b at both ends of the sieve 2006c are started to rotate the sieve, and the aggregate falls into the output receiving hopper 4103d. At this time, the output receiving hopper 4103d is retracted and moved above the temporary storage hopper 4104 at the end of the L-shaped track 4102. The output rotating motor 4103c is controlled to rotate, driving the output receiving hopper 4103d to rotate, and part of the aggregate falls into the temporary storage hopper 4104 for storage. The excess aggregate can restore the output receiving hopper 4103d to the uppermost end of the L-shaped track 4102 and be pushed out by the output electric push rod 4103b and rotated in cooperation with the output rotating motor 4103c to pour the aggregate back into the sieve 2006c of the transfer box. Thereafter, with the assistance of construction workers, the aggregate in the temporary storage hopper 4104 can be taken and placed into the laser particle size analyzer 4001 for analysis, and finally the average particle size and particle size distribution curve of the aggregate this time are obtained. The transfer box moves to the light transmission analysis interface 1004c for the light transmission analysis process;

[0064] S4, light transmission analysis: When the transfer box arrives at the light transmission analysis interface 1004c, part of the aggregate is transferred to the temporary storage hopper 4104 of the aggregate output unit 4100 in the same manner as above, and the construction personnel assist in spreading the aggregate on the glass plate 4201a. At this time, the laser rangefinder matrix 4205 can be activated to monitor the height of the aggregate particle bed on the glass plate in real time, and at the same time, the first electric push rod 4203b and the second electric push rod 4203c of the scraper are pushed out to drive the alloy scraper 4203d to move back and forth on the glass plate 4201a to scrape it flat, so that the particle bed height on the glass plate 4201a meets the requirements. If the aggregate meets the requirements, the transmittance meter 4201 is started to analyze the transmittance of the aggregate particles. Finally, the aggregate particle size range of the second rectification batch is determined to be in compliance with the standards according to the obtained transmittance, average particle size and particle size distribution curve. If it meets the standards, the transfer box can be moved to the compliance output interface 1004d for storage. If it does not meet the standards, it can be transported to the non-compliant output interface 1004e for storage or the above-mentioned second rectification and monitoring process can be repeated on the transfer track 1004 to obtain the aggregate particles that have been rectified three times, which are circulated in sequence until they meet the standards and are stored in the storage box 5002 of the compliance storage unit 5100.

[0065] S5. Output storage: After the rectification and testing processes are completed, the aggregate arrives at the output interface for output. The aggregate is transferred from the screen 2006c of the transfer box to the output hopper 4103d in the same way as the above-mentioned aggregate output unit 4100, and then transferred from the output hopper 4103d to the storage box 5002. Different storage boxes can circulate on the storage track 5001 to store aggregate particles of different particle sizes. At this point, the batch intelligent control of the particle size of the rectified recycled aggregate is completed.

[0066] The method for batch intelligent adjustment of recycled aggregate particle size of the present invention can be directly applied in the existing recycled aggregate particle size adjustment process. The aggregate is initially rectified by the jaw crusher 1003, and then the aggregate is secondary rectified by the impact crushing head 3007 and the screening electric push rod 3002. Subsequently, the laser particle size analyzer and the transmittance meter 4201 and other mechanisms are used to monitor whether the particle size after the secondary rectification meets the required range. If it meets the rules, it can be directly transported to the storage box of the compliant storage unit 5100 for storage. If it does not meet the rules, the above rectification and monitoring process are repeated until it meets the rules. This method has a high efficiency in rectifying the recycled aggregate and the rectification process is completed on a circulating production line, which is easy to control and is relatively intelligent. It can better save the energy consumption required for regulating the aggregate particle size and effectively improve the efficiency of batch adjustment of the recycled aggregate particle size.

[0067] The above description is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be understood by anyone familiar with the technology within the technical scope disclosed by the present invention should be included in the scope of the present invention.

At this time, the transfer box is first moved to the area below the impact crushing head (3007) so that its screen (2006c) is located in the closed area on the right side of the transfer box and corresponds to the impact crushing head (3007) above it. At this time, the drive motor (3006) is controlled to drive the impact crushing head (3007) to descend and move back and forth to perform secondary rectification on the aggregate in the top layer of the screen (2006c). The impact crushing and vibration screening processes are completed alternately. If necessary, such as performing secondary rectification on the aggregate in the second-layer screen (2006c), the top-layer screen (2006c) is controlled to move to the hollow area by the screening electric trolley (2006a), and then the crushing electric push rod (3004) is controlled to lower the impact crushing head mounting seat (3005) to an appropriate height, and the above-mentioned impact crushing process is repeated to perform secondary rectification on the aggregate in the second-layer screen (2006c). Similarly, the third layer is also completed with secondary rectification in the same way. After the secondary rectification and screening are completed, the transfer box is controlled to move to the particle size analysis interface (1004b) for the particle size analysis process; S3. Particle size analysis: When the transfer box comes near the particle size analysis interface (1004b), the particle size analysis process is carried out. The transfer box is rotated by the rotating motor at the bottom of the transfer box so that its hollow part is close to the aggregate output unit (4100). At this time, according to the actual detection needs, the sieve mesh (2006c) to be detected is controlled to move to the hollow area through its screening electric trolley (2006a). Then, the electric trolley on the L-shaped track (4102) is controlled to drive the output electric push rod mounting plate (4103a) thereon to move on the vertical track to a height lower than the sieve mesh (2006c). The output rotating motor (4103c) at the output end of the output electric push rod mounting plate (4103a) and the output receiving hopper (4103d) thereon are controlled so that the output receiving hopper (4103d) is inserted into the transfer box through the baffle opening (2002a) of the hollow structure. The screening rotating motors (2006b) at both ends of the sieve mesh (2006c) are started to rotate the sieve mesh, and the aggregate falls into the output receiving hopper (4103d). At this time, the output receiving hopper (4103d) is retracted and moved above the temporary storage hopper (4104) at the end of the L-shaped track (4102). The output rotating motor (4103c) is controlled to rotate, driving the output receiving hopper (4103d) to rotate, and part of the aggregate falls into the temporary storage hopper (4104) for storage. The excess aggregate restores the output receiving hopper (4103d) to the uppermost end of the L-shaped track (4102), and is pushed out by the output electric push rod (4103b) and combined with the rotation of the output rotating motor (4103c) to pour the aggregate back into the sieve mesh (2006c) of the transfer box. After that, with the assistance of construction workers, the aggregate in the temporary storage hopper (4104) is taken and placed into the laser particle size analyzer (4001) for analysis. Finally, the average particle size and particle size distribution curve of the aggregate this time are obtained, and the transfer box moves to the light transmission analysis interface (1004c) for the light transmission analysis process; S4, light transmission analysis: When the transfer box arrives at the light transmission analysis interface (1004c), part of the aggregate is transferred to the temporary storage hopper (4104) of the aggregate output unit (4100) in the same manner as above, and the construction personnel assist in spreading the aggregate on the glass plate (4201a). At this time, the laser rangefinder matrix (4205) is started to monitor the height of the aggregate particle bed on the glass plate in real time, and at the same time, the first electric push rod (4203b) and the second electric push rod (4203c) of the scraper are pushed out to drive the alloy scraper (4203d) to move back and forth on the glass plate (4201a) to scrape and level the particles on the glass plate (4201a). The height of the particle bed meets the requirements. At this time, the transmittance meter (4201) is started to analyze the transmittance of the aggregate particles. Finally, the secondary rectification aggregate particle size range is determined to meet the standards based on the obtained transmittance, average particle size, and particle size distribution curve. If it meets the standards, the transfer box is moved to the compliant output interface (1004d) for storage. If it does not meet the standards, it is transported to the non-compliant output interface (1004e) for storage or the above secondary rectification and monitoring procedures are repeated on the transfer track (1004) to obtain tertiary rectified aggregate particles, which are circulated in sequence until they meet the standards and are stored in the storage box (5002) of the compliant storage unit (5100); S5. Output storage: After the rectification and testing processes are completed, the aggregate arrives at the output interface for output. The aggregate is transferred from the screen (2006c) of the transfer box to the output receiving hopper (4103d) in the same way as the above-mentioned aggregate output unit (4100), and then transferred from the output receiving hopper (4103d) to the storage box (5002). Different storage boxes circulate on the storage track (5001) to store aggregate particles of different particle sizes. At this point, the batch intelligent control of the particle size of the rectified recycled aggregate is completed.
