However, since the device can only perform knocking detection on one side of the brick and cannot detect the other sides of the brick, when the other sides of the brick are defective, only one side of the brick is tested for strength, and the obtained brick strength test data is inaccurate, which causes the bricks used in the building to be of substandard quality, affecting the service life of the building or causing the subsequent acceptance of the building to be substandard.

[0030] The working steps of this embodiment are: The following rotations are from front to back, from top to bottom, and from right to left. When in use, first place the performance testing device for building construction materials at a required location; The operator connects an external power supply to all components that require electric drive. The operator sets two conveyor belts for conveying aerated concrete blocks in front of the device. One of the conveyor belts is aligned with the gap 4001, and is used to convey the aerated concrete blocks after production from the gap 4001 to the turntable 3. The other conveyor belt is aligned with the gap 4002, and is used to receive the aerated concrete blocks after testing discharged from the gap 4002. When the external conveyor belt conveys the aerated concrete blocks from the gap 4001 to the turntable 3 to perform strength testing on the first side of the aerated concrete blocks, the output shaft of the control motor 101 drives the spur gear 102 to rotate clockwise, and the spur gear 102 drives the gear ring 103, the slip ring 2, the turntable 3, the push block 8 and the aerated concrete blocks to rotate counterclockwise to move the aerated concrete blocks. After the concrete block rotates until the center point and the hammer head 7 at the right quarter point of the base 1 are on the same axis, the output shaft of the control motor 101 stops rotating, and then the output shaft of the motor 203 at the right quarter point of the base 1 is controlled to rotate counterclockwise, driving the corresponding connecting rod 202 and the hammer head 7 to rotate counterclockwise together, so that the hammer head 7 knocks on the upper surface of the aerated concrete block, and the strength performance of the first surface of the aerated concrete block is tested. After the hammer head 7 finishes knocking, the output shaft of the control motor 203 rotates clockwise to drive the connected components to reset; it should be noted that during the detection process, the camera 307 is used to monitor the aerated concrete block after the detection to monitor whether cracks or fragments appear in the aerated concrete block after the knocking, that is, to monitor whether the quality of the knocking test of the aerated concrete block meets the standards; After the hammer head 7 is reset, the output shaft of the control motor 101 continues to rotate clockwise, driving the connected components and the aerated concrete block to continue to rotate counterclockwise. At this time, as the aerated concrete block rotates counterclockwise, the aerated concrete block will contact the flip assembly, that is, as the aerated concrete block rotates counterclockwise, the aerated concrete block will be intercepted by the two wedge blocks 303. At this time, the side of the aerated concrete block intercepted by the wedge blocks 303 is in the same vertical plane as the limit rod 304. As the turntable 3 continues to rotate, the aerated concrete block is stationary compared to the turntable 3. When the push block 8 connected to the turntable 3 rotates to the bottom of the aerated concrete block and contacts the limit rod 304, due to the connection between the push block 8 and the turntable 3 The push block 8 is located above the limit rod 304, that is, as the push block 8 is driven to rotate on the turntable 3, the push block 8 is forced to gradually flip upward with the connection with the turntable 3 as the rotation point under the restriction of the limit rod 304, and the flipping angle of the push block 8 tends to ninety degrees, thereby pushing the aerated concrete block intercepted by the two wedge blocks 303 to flip upward, and turning the upper surface of the aerated concrete block to the side, and the side of the aerated concrete block originally intercepted by the wedge block 303 rotates downward and contacts the two wedge blocks 303, and the two wedge blocks 303 are forced to drive the spring telescopic rod 302 to automatically contract, and the aerated concrete block is undertaken by the two wedge blocks 303, and under the action of the spring telescopic rod 302, the aerated concrete block will be clamped. The aerated concrete block 302 is held in place, that is, it is restricted during the flipping process to prevent the aerated concrete block from flipping over on both sides when the aerated concrete block is pushed upward by the push block 8. When the aerated concrete block is flipped over by the push block 8, the turntable 3 continues to drive the push block 8 to rotate. During the rotation process, the push block 8 will continue to be restricted by the limit rod 304, so that the push block 8 remains in the flipped state and pushes the aerated concrete block out of the clamping of the two wedge blocks 303, so that the turntable 3 continues to rotate and can drive the flipped aerated concrete block to move. When the center of the flipped aerated concrete block moves to the same axis as the hammer head 7 at the quarter point on the rear side of the base 1, the output shaft of the control motor 101 stops rotating. The second motor 203 at the quarter point on the rear side of the base 1 is controlled to rotate counterclockwise, driving the corresponding connecting rod 202 and the hammer head 7 to rotate counterclockwise, so that the hammer head 7 strikes the upper surface of the aerated concrete block after the flipping, and the strength performance of the second surface of the aerated concrete block is tested; it should be noted that after the aerated concrete block is flipped, as the turntable 3 drives the push block 8 to rotate, the push block 8 pushes the aerated concrete block to break away from the clamping of the two wedge blocks 303. The time for the aerated concrete block to break away from the two wedge blocks 303 is shorter than the time for the push block 8 to break away from the limit rod 304, ensuring that the aerated concrete block will not be clamped by the two wedge blocks 303, affecting the subsequent detection of the aerated concrete block; When the push block 8 is free from the restriction of the limit rod 304, the push block 8 will automatically reset under the action of gravity, and after the aerated concrete block undergoes the second side detection, the output shaft of the control motor 101 continues to drive the turntable 3 to rotate, and the turntable 3 drives the aerated concrete block after the second side detection to contact the subsequent flipping assembly, and then the above-mentioned flipping operation of the aerated concrete block is fully performed, so that the center of the aerated concrete block and the hammer head 7 of the subsequent knocking assembly are on the same axis, and then the third side detection is performed. After the multi-side detection of the aerated concrete block is completed, the output shaft of the control motor 101 continues to rotate clockwise, driving the connected components and the aerated concrete block to continue to rotate counterclockwise, and the aerated concrete block after the detection is rotated to the notch. After the second 4002, the aerated concrete block is intercepted by the two gear bars 501, and then the telescopic part of the electric push rod 503 is controlled to be pushed out, driving the arc push plate 504 to move together, pushing the tested aerated concrete block out from the gap 4002 and onto the conveyor belt to the subsequent process. In this way, the three knocking components and the two flipping components cooperate with each other to turn the aerated concrete block rotating with the turntable 3 over, and knock on multiple surfaces of the aerated concrete block, thereby realizing multi-faceted strength detection of the aerated concrete block, making the collected aerated concrete block strength detection data more complete and accurate, and avoiding the problem of substandard quality of the tested aerated concrete block in subsequent use.

[0031] It should be noted that, during the flipping process, the aerated concrete block will fall on the two wedge blocks 303, forcing the two wedge blocks 303 to move to opposite sides, and the two spring telescopic rods 302 will automatically shrink, and the flipped aerated concrete block will be supported by the two wedge blocks 303, playing a buffering role, thereby avoiding the problem of the aerated concrete block being offset or flipped multiple times during the flipping process.

[0032] It should be noted that the device can realize batch strength testing of aerated concrete blocks, that is, after the first side of the aerated concrete blocks are tested, the conveyor belt conveys the blocks to be tested subsequently to the turntable 3 through the gap 4001, and when the second side of the aerated concrete blocks is tested after the first side is tested, the newly delivered blocks are tested on the first side, and the conveyor belt again conveys the blocks to be tested subsequently to the turntable 3 through the gap 4001.

[0033] Example 2 On the basis of Example 1, Figure 5-Figure 6As shown, a cleaning component is also included, and each mounting seat 201 is connected to a cleaning component; the cleaning component includes a fixed block 201, an electric push rod 202 and an arc-shaped push plate 203; two fixed blocks 201 are fixedly connected to the mounting seat 201; each fixed block 201 is bolted with an electric push rod 202; the telescopic part of each electric push rod 202 passes through the limit frame 4; the telescopic part of each electric push rod 202 is fixedly connected to an arc-shaped push plate 203; the arc-shaped push plate 203 is in contact with the side of the limit frame 4 facing the turntable 3, and the lower surface of the arc-shaped push plate 203 is in contact with the upper surface of the turntable 3.

[0034] The limiting cylinder 6 is provided with three discharge openings 6001 , and each discharge opening 6001 is directly opposite to the corresponding arc-shaped push plate 2 403 .

[0035] The cleaning assembly also includes an annular hollow tube 404 and an air inlet pipe 405; the annular hollow tube 404 is fixedly connected to the limiting frame 4; the annular hollow tube 404 is connected to a plurality of equally distributed air inlet pipes 405; the lower side of the annular hollow tube 404 is provided with a plurality of blowing holes 40401 facing the upper surface of the turntable 3.

[0036] It also includes a guide plate 406; the limit frame 4 and the limit cylinder 6 are fixedly connected with a guide plate 406 for intercepting and cleaning debris falling from the turntable 3, and the lower surface of the guide plate 406 is in contact with the upper surface of the turntable 3; the limit cylinder 6 is provided with a slag discharge port 6002, and the debris intercepted by the guide plate 406 falls into the limit cylinder 6 through the slag discharge port 6002.

[0037] It also includes a crushing assembly, which is connected to the inner side of the cylinder 5; the crushing assembly includes a connecting frame 601, a crushing box 602 and a guide cylinder 603; two connecting frames 601 are fixedly connected to the inner side of the cylinder 5; the crushing box 602 is installed on the two connecting frames 601; the guide cylinder 603 is fixedly connected to the upper part of the crushing box 602, and the guide cylinder 603 is fixedly connected to the cylinder 5.

[0038] The working principle of this embodiment is: The operator connects an external power supply to all components that need to be powered by electricity, connects an external air blowing device to the air inlet pipe 405 , and places a powder conveyor belt under the crushing box 602 .

[0039] In Example 1, when the camera 307 is used to monitor the aerated concrete blocks after inspection, if the camera 307 detects that the aerated concrete blocks have cracks or breakages, it means that the strength performance of the aerated concrete blocks does not meet the requirements. At this time, the telescopic parts of the two electric push rods 402 located at the corresponding knocking components are controlled to be pushed out, driving the arc push plate 403 to move toward the limiting cylinder 6, and pushing the unqualified aerated concrete blocks toward the limiting cylinder 6 together, so that the unqualified aerated concrete blocks enter the guide cylinder 603 and the crushing box 602 from the discharge port 6001. At this time, the crushing box 602 is controlled to open, and the unqualified aerated concrete blocks are crushed, so that the unqualified aerated concrete blocks are crushed into debris, and the debris crushed by the crushing box 602 will fall to the powder conveyor belt, and the crushed debris will be transported away for reuse through the conveyor belt, saving the raw material resources of the aerated concrete blocks.

[0040] Considering that during the percussion test of the aerated concrete block by the hammer head 7, the aerated concrete block will produce debris falling on the turntable 3. If the subsequent aerated concrete blocks are placed on the debris for percussion test, due to the uneven contact between the aerated concrete block and the test surface, some parts may be subjected to greater pressure, resulting in stress concentration, and the stress concentration point will become the weak point of the aerated concrete block, thereby causing the aerated concrete block to crack or even break, affecting the detection accuracy of the subsequent aerated concrete blocks. Therefore, the first test block is driven on the turntable 3. The tested aerated concrete block moves to the gap 4002, and the arc-shaped push plate 504 pushes the tested aerated concrete block out of the gap 4002. As the turntable 3 continues to rotate, the debris falling on the turntable 3 will be blocked by the guide plate 406, so that the debris remaining on the turntable 3 can be scraped off by the guide plate 406, and under the rotation of the turntable 3 and the guidance of the guide plate 406, the debris will enter the guide cylinder 603 from the slag discharge port 6002, so that it can be ensured that the subsequent aerated concrete blocks will not be affected by the residual debris when they are placed on the turntable 3.

[0041] It should be noted that when the arc-shaped push plate 2 403 pushes the unqualified aerated concrete blocks toward the limiting cylinder 6, the debris within the moving range of the arc-shaped push plate 2 403 will also be pushed into the guide cylinder 603, thereby reducing the difficulty of the guide plate 406 in scraping off the debris and avoiding excessive debris, which will cause a large amount of debris to accumulate on the side of the guide plate 406, making it easy for the debris to pass over the guide plate 406.

[0042] It should be noted that during the inspection of aerated concrete blocks, the external fan is controlled to be turned on, and the airflow is continuously delivered to the air inlet pipe 405 and the annular hollow tube 404, and then blown out from the several blowing holes 40401 of the annular hollow tube 404 to blow away the debris on the aerated concrete blocks to avoid affecting the knocking detection of the hammer head 7, and at the same time avoid affecting the monitoring of the aerated concrete blocks after the inspection by the camera 307, and the airflow blown out from the blowing hole 40401 can also cooperate with the arc push plate 2 403 to clean up the debris.

[0043] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
