[0021] 1. For the concrete block detection device, through the cooperation among the air flow groove, the air pressure plate and the magnetic plate, during the rotation of the driving disc, air flow will be continuously conveyed into the air blowing pipe along the air guide pipe, and a suction force will also be generated in the air extraction groove, so as to generate a downward thrust on the top of the test block and a suction force at the bottom.

[0035] Embodiment 1:

[0036] Refer to Figures 1-8 , a concrete block detection device, including a detection table 1, and further including: a pressure seat 2 fixed on the top of the detection table 1, pressure rods 21 are slidably connected to the symmetric side walls of the pressure seat 2, and a pressure supply part for driving the pressure rods 21 to slide is arranged in the detection table 1. Among them, a blowing part for directionally guiding the dust generated when the material is crushed under pressure is arranged on the pressure seat 2; a scrap material groove 3 opened inside the detection table 1, and a rolling part for crushing the damaged material under pressure is arranged in the scrap material groove 3. Among them, a dust reduction part for spraying water mist when crushing the material is arranged in the detection table 1.

[0037] Refer to Figure 3 , Figure 5 , Figure 7 and Figure 8, wherein the pressure supply part includes a piston cylinder 4, the piston cylinder 4 is fixed on the detection platform 1, pressure grooves 41 are provided on both sides of the pressure seat 2, a pressure plate 411 is slidably connected in the pressure groove 41, a first spring 412 is fixedly connected between the side wall of the pressure plate 411 and the pressure groove 41, the pressure rod 21 penetrates into the pressure groove 41 and is fixedly connected to the side wall of the pressure plate 411, a mounting groove 42 is provided in the detection platform 1, and the mounting groove 42 is communicated with the inner cavity of the piston cylinder 4, a driving disk 421 is rotatably connected in the mounting groove 42, a piston plate 43 is slidably connected in the piston cylinder 4, a linkage rod 431 is hinged at the bottom of the piston plate 43, and the linkage rod 431 The bottom end is rotatably connected to the side wall of the driving disk 421, and both sides of the piston cylinder 4 are fixed and connected with an inflation tube 44, the other end of the inflation tube 44 is connected to the inner cavity of the pressure groove 41, and pressure gauges 441 are fixedly connected to the inflation tubes 44 on both sides; the rolling part includes two rolling rollers 5, the rolling rollers 5 are rotatably connected in the crushing trough 3, and the ends of the rotating shafts of the two rolling rollers 5 are meshed and connected by a gear set 51, and the side wall of the detection platform 1 is fixedly connected with a driving motor 52, and the output shaft of the driving motor 52 is fixedly connected to the end of the rotating shaft of the rolling roller 5, and the rotating shaft of the rolling roller 5 and the rotating shaft of the driving disk 421 are connected through a pulley set 53.

[0038] By setting the above structure, the driving motor 52 is turned on, and the driving disc 421 is driven to rotate through the transmission action of the pulley group 53, so that the linkage rod 431 pushes the piston plate 43 to slide in the piston cylinder 4 up and down. When the piston plate 43 slides upward, the gas in the piston cylinder 4 will be compressed, so that the gas enters the pressure grooves 41 on both sides along the inflation tube 44 at the same time, thereby pushing the pressure plates 411 on both sides and the pressure rod 21 to approach the sample block and squeeze the sample block. At this time, the gas pressure reading on the pressure gauge 441 is recorded, and combined with the end area of ​​the pressure rod 21, the pressure on the sample block can be obtained; and when the sample block is completely penetrated and crushed, it will fall downward into the crushing trough 3. At this time, under the action of the rotation and crushing of the two crushing rollers 5, the crushed sample block will be crushed into granular blocks for subsequent recycling and transportation, and there is no need to manually clean the crushed materials, which reduces manpower consumption and improves detection efficiency.

[0039] Reference Figure 7 , Figure 8, wherein, the blowing part includes a blowing air pipe 6, the blowing air pipe 6 is fixed on the side wall of the pressure seat 2, an air flow groove 61 is formed in the detection table 1, a pneumatic plate 611 is slidably connected in the air flow groove 61, a second spring 612 is fixedly connected between the bottom of the pneumatic plate 611 and the air flow groove 61, the side wall of the air flow groove 61 is fixedly connected and communicated with a guide air pipe 62, the other end of the guide air pipe 62 is communicated with the inner cavity of the blowing air pipe 6, and a plurality of groups of blowing holes are equally spaced at the bottom of the blowing air pipe 6. A magnetic plate 422 is fixedly connected to the side wall of the driving disc 421, and the magnetic plate 422 and the pneumatic plate 611 repel each other magnetically; A suction pipe 45 is fixedly connected and communicated with the side wall of the piston cylinder 4, a suction groove 451 is formed in the detection table 1, the top end of the suction groove 451 penetrates to the surface of the detection table 1 and is communicated with the suction pipe 45, and a filter screen 452 is fixedly connected in the suction pipe 45. The filter screen 452 is used to filter out the shredded materials and dust carried in the air flow. The bottom end of the suction groove 451 is communicated with the inner cavity of the shredding groove 3, and one-way valves are arranged in both the suction pipe 45 and the charging pipe 44; An air suction groove 613 is formed between the air flow groove 61 and the suction groove 451, and one-way valves are arranged in both the air suction groove 613 and the guide air pipe 62.

[0040] It should be noted that the one-way valve in the suction pipe 45 only allows new air flow to enter the piston cylinder 4; the one-way valve in the charging pipe 44 only allows the air flow in the piston cylinder 4 to enter the pressure groove 41; the one-way valve in the air suction groove 613 only allows the air flow to enter the air flow groove 61; the one-way valve in the guide air pipe 62 only allows the air flow to enter the blowing air pipe 6; in addition, a pressure relief valve is arranged on the charging pipe 44, which can restore the air pressure filled in from the piston cylinder 4 to the initial state after the detection is completed, so as to be used for the next detection.

[0041] With the above structure, when the piston plate 43 moves downward, a suction force will be generated at the top of the piston cylinder 4, opening the check valve in the suction pipe 45. At this time, new gas will be input into the piston cylinder 4 along the crushing groove 3, the suction groove 451, and the suction pipe 45. Moreover, the suction force generated at the bottom of the crushing groove 3 will cause the air flow to move from around the specimen block into the crushing groove 3, thereby guiding the debris and dust generated when the specimen block is crushed under pressure into the crushing groove 3. During the rotation of the driving disk 421, due to the repulsive force between the magnetic plate 422 and the air pressure plate 611, the air pressure plate 611 will retract into the air flow groove 61, compressing the gas in the air flow groove 61 and opening the check valve in the air guide pipe 62, allowing the air flow to enter the air blowing pipe 6 along the air guide pipe 62 and be discharged downward from the air blowing pipe 6. When the magnetic plate 422 and the air pressure plate 611 leave the repulsive area, under the rebounding action of the second spring 612, the air pressure plate 611 will reset, generating a suction force at the bottom of the air flow groove 61 and opening the check valve in the suction groove 613. At this time, air flow will be sucked from the suction groove 451, increasing the overall suction force in the suction groove 451 and improving the dust collection effect. In this way, by the method of blowing from above and sucking from below, dust diffusion outward is effectively avoided, and the cleanliness of the detection area is improved.

[0042] Refer to Figure 4 、 Figure 5 , wherein, two groups of buffer grooves 22 are symmetrically formed in the pressure seat 2. The buffer grooves 22 communicate with the inner cavity of the pressure groove 41. A buffer plate 221 is slidably connected in the buffer grooves 22. A third spring 222 is fixedly connected between the buffer plate 221 and the buffer grooves 22. The buffer plate 221 is in movable contact with the pressure plate 411, and both ends of the air blowing pipe 6 communicate with the inner cavities of the two sides of the buffer grooves 22 respectively.

[0043] With the above structure, at the moment when the specimen block is completely crushed, the pressure rod 21 will lose the resistance effect, and the air pressure in the pressure groove 41 will cause the pressure rod 21 to move forward instantaneously. At this time, the pressure plate 411 will hit the buffer plate 221. By using the damping effect generated between the buffer plate 221 and the third spring 222, the impact force on the pressure plate 411 is buffered, reducing the impact force on the pressure plate 411 and improving the protection of the pressure plate 411. Moreover, after the pressure plate 411 hits the buffer plate 221, the buffer plate 221 will retract into the buffer groove 22, compressing the gas in the buffer groove 22 and causing this part of the gas to enter the air blowing pipe 6, thereby increasing the downward blowing effect generated by the air blowing pipe 6 at this time and pushing a large amount of dust generated at the moment of specimen block crushing into the crushing groove 3, improving the cleanliness of the test area.

[0044] Refer to Figure 4 、 Figure 6, wherein the dust-removing part includes a water storage tank 7 which is arranged in the detection table 1. A water squeezing plate 71 is slidably connected in the water storage tank 7. A protective groove 72 is formed in the side wall of the crushing material tank 3. A pressure atomizing nozzle 721 is fixedly connected in the protective groove 72. The pressure atomizing nozzle 721 communicates with the inner cavity of the water storage tank 7. A water supply tank 73 is fixedly connected to the top of the detection table 1. The bottom of the water supply tank 73 is fixedly connected and communicated with a water supply pipe 731. The bottom end of the water supply pipe 731 penetrates through the water storage tank 7 and the water squeezing plate 71 and extends to the bottom of the water storage tank 7; A pressurizing groove 74 is formed between the bottom of the pressure groove 41 and the top of the water storage tank 7. An electromagnetic valve is arranged in the pressurizing groove 74. Electrode plates 741 are fixedly connected to the sides of the buffer plate 221 and the pressure plate 411 close to each other. The two groups of electrode plates 741 are aligned with each other, and the electrode plates 741 are electrically connected to the electromagnetic valve.

[0045] It should be noted that the water pressure existing in the water storage tank 7 and the water supply tank 73 cannot drive the water flow to pass through the pressure atomizing nozzle 721. After applying pressure to the water, the water flow can pass through the pressure atomizing nozzle 721 and spray out.

[0046] Through the setting of the above structure, when the pressure plate 411 contacts the buffer plate 221, the two groups of electrode plates 741 will also fit together, thereby opening the electromagnetic valve in the pressurizing groove 74, so that the air pressure in the pressure groove 41 is transmitted to the water storage tank 7, and the water squeezing plate 71 is pushed to move downward, thereby generating a pressure effect on the water flow in the water storage tank 7, making it pass through the pressure atomizing nozzle 721 and spray into the crushing material tank 3. At this time, the dust is captured by the water mist, effectively improving the dust-removing effect, and the water mist will also adhere to the surface of the rolling roller 5, thereby reducing the thermal wear of the rolling roller 5 and improving the service life of the rolling roller 5.

[0047] Refer to Figures 1-8, in the present invention, during use, first place the sample block of autoclaved aerated concrete brick on the detection table 1 and push it into the concave part of the pressure seat 2 so that it is erected on the top of the crushing groove 3. Then, turn on the driving motor 52. Through the transmission of the pulley group 53, the driving disc 421 will be driven to rotate, causing the linkage rod 431 to reciprocate up and down to push the piston plate 43 to slide in the piston cylinder 4. When the piston plate 43 slides upward, the gas in the piston cylinder 4 will be compressed, and the one-way valve in the charging pipe 44 will be opened, allowing the gas to enter both pressure grooves 41 along the charging pipe 44 at the same time, thereby pushing both pressure plates 411 to drive the pressure rods 21 to approach the sample block. When the piston plate 43 moves downward, a suction force will be generated at the top of the piston cylinder 4, causing the one-way valve in the suction pipe 45 to be opened. At this time, new gas will be input into the piston cylinder 4 along the crushing groove 3, the air extraction groove 451, and the suction pipe 45. Repeating the above process, both pressure rods 21 will squeeze the sample block. At this time, record the air pressure reading on the pressure gauge 441, and combined with the end area of the pressure rod 21, the pressure received by the sample block can be obtained. And the suction force generated at the bottom of the crushing groove 3 will cause the air flow to move from around the sample block into the crushing groove 3, thereby guiding the debris and dust generated when the sample block is crushed under pressure into the crushing groove 3. During the rotation of the driving disc 421, due to the repulsive action between the magnetic plate 422 and the air pressure plate 611, the air pressure plate 611 will retract into the air flow groove 61, thereby compressing the gas in the air flow groove 61 and opening the one-way valve in the air guide pipe 62, allowing the air flow to enter the blowing pipe 6 along the air guide pipe 62 and be discharged downward from the blowing pipe 6. When the magnetic plate 422 and the air pressure plate 611 are out of the repulsive area, under the rebounding action of the second spring 612, the air pressure plate 611 will reset, causing a suction force to be generated at the bottom of the air flow groove 61, opening the one-way valve in the air suction groove 613. At this time, air flow will be sucked from the air extraction groove 451, thereby increasing the overall suction force in the air extraction groove 451 and improving the dust collection effect. In this way, through the method of blowing from above and sucking from below, dust diffusion outward is effectively avoided, and the cleanliness of the detection area is improved.

[0048] When the specimen block is completely penetrated and crushed, it will fall downward into the crushing bin 3. At this time, under the rolling action of the two rolling rollers 5, the crushed specimen block will be rolled into granular blocks for subsequent recycling and transportation. At the moment when the specimen block is completely crushed, the pressure rod 21 will lose the resistance effect, and the air pressure in the pressure groove 41 will push the pressure rod 21 forward instantaneously. At this time, the pressure plate 411 will hit the buffer plate 221. By using the damping effect generated between the buffer plate 221 and the third spring 222, the impact force of the pressure plate 411 is buffered, the impact force received by the pressure plate 411 is reduced, the protection of the pressure plate 411 is improved. Moreover, after the pressure plate 411 hits the buffer plate 221, the buffer plate 221 will retract into the buffer groove 22, compressing the gas in the buffer groove 22 and causing this part of the gas to enter the air blowing pipe 6, thereby increasing the downward blowing effect generated by the air blowing pipe 6 at this time, pushing a large amount of dust generated during the instant of specimen block crushing to move into the crushing bin 3, and cooperating with the suction effect generated in the air extraction groove 451, further reducing the possibility of dust diffusion and improving the cleanliness in the detection area. Moreover, when the pressure plate 411 contacts the buffer plate 221, the two electrode plates 741 will also fit together, thereby opening the solenoid valve in the pressurizing groove 74, causing the air pressure in the pressure groove 41 to be conveyed to the water storage tank 7, and pushing the water squeezing plate 71 to move downward, thereby generating a pressure effect on the water flow in the water storage tank 7, causing it to pass through the pressure atomizing nozzle 721 and spray into the crushing bin 3. At this time, the dust is captured by the water mist, effectively improving the dust reduction effect, and the water mist will also adhere to the surface of the rolling roller 5, thereby reducing the thermal wear of the rolling roller 5 and improving the service life of the rolling roller 5.

[0049] Embodiment 2:

[0050] Refer to Figures 1-8 , which is basically the same as Embodiment 1. On the basis of Embodiment 1, a method for detecting concrete blocks is proposed, and the steps are as follows:

[0051] Step 1. Place the specimen block at the concave part of the pressure seat 2: Place the specimen block of autoclaved aerated concrete brick on the detection table 1 and push it into the concave part of the pressure seat 2 so that it is erected on the top of the crushing bin 3.

[0052] Step 2, apply pressure to the sample block through the pressure rods 21 on both sides to test the compressive strength: by turning on the drive motor 52, the drive disk 421 will be driven to rotate through the transmission action of the pulley group 53, so that the linkage rod 431 pushes the piston plate 43 up and down to slide in the piston cylinder 4. When the piston plate 43 slides upward, the gas in the piston cylinder 4 will be compressed, so that the gas enters the pressure grooves 41 on both sides along the inflation tube 44 at the same time, thereby pushing the pressure plates 411 on both sides and the pressure rods 21 to approach the sample block and squeeze the sample block. At this time, record the air pressure reading on the pressure gauge 441, and then combine it with the end area of ​​the pressure rod 21 to obtain the pressure on the sample block.

[0053] Step 3: Directly guide the crushed debris generated during the compression of the sample block: when the piston plate 43 moves downward, a suction effect will be generated at the top of the piston cylinder 4. At this time, new gas will be input into the piston cylinder 4 along the crushing groove 3, the exhaust groove 451 and the exhaust pipe 45, and the suction effect generated at the bottom of the crushing groove 3 will cause the air flow to move from the surrounding of the sample block to the crushing groove 3, so as to guide the debris dust generated when the sample block is compressed and destroyed into the crushing groove 3. In the process of rotation of the driving disk 421, the repulsion between the magnetic plate 422 and the air pressure plate 611 will cause the air pressure plate 611 to move toward the air. The flow groove 61 retracts to compress the gas in the air flow groove 61, so that the air flow enters the blowing pipe 6 along the air guide pipe 62 and is discharged downward by the blowing pipe 6. When the magnetic plate 422 and the air pressure plate 611 are separated from the repulsive area, the air pressure plate 611 will be reset under the rebound action of the second spring 612, so that suction is generated at the bottom of the air flow groove 61. At this time, the air flow will be sucked in from the exhaust groove 451, thereby increasing the overall suction effect in the exhaust groove 451 and improving the dust collection effect. In this way, the directional guidance of dust is achieved by blowing up and sucking down, which effectively prevents the dust from spreading outward and improves the cleanliness in the detection area.

[0054] Step 4, crush and recover the sample blocks that have been destroyed by pressure: when the sample blocks are completely penetrated and crushed, they will fall downward into the crushing trough 3. At this time, under the action of the rotation and crushing of the two crushing rollers 5, the crushed sample blocks will be crushed into granular blocks for subsequent recycling and transportation; and after the sample blocks are crushed, the pressure plate 411 will contact the buffer plate 221, and the two sets of electrode sheets 741 will also fit together, thereby opening the solenoid valve in the pressurizing tank 74, so that the air pressure in the pressure tank 41 is transmitted to the water storage tank 7, and the water squeezing plate 71 is pushed to move downward, thereby exerting pressure on the water flow in the water storage tank 7, so that it passes through the pressure atomizing nozzle 721 and is sprayed into the crushing trough 3. At this time, water mist is used to capture dust, which effectively improves the dust reduction effect, and the water mist will also adhere to the surface of the crushing roller 5, thereby reducing the thermal wear of the crushing roller 5 and increasing the service life of the crushing roller 5.
