[0023] Among them, the shielding part includes an upper shell 3, which is slidably mounted on the four groups of guide rods 2, and the top of the upper shell 3 is fixedly connected to the top of the pressure plate 23 through a bending plate 31, and a lower shell 32 is slidably inserted into the bottom of the inner cavity of the upper shell 3, and multiple groups of pulling ropes 33 are fixedly connected between the top of the lower shell 32 and the top of the upper shell 3.

[0024] Through the arrangement of the above-mentioned structure, when the pressure plate 23 moves downward, the upper shell 3 will be driven to slide downward along the guide rod 2, and finally the lower shell 32 will fit on the top of the test platform 1, wrapping the concrete test block during the compression test to avoid the splashing of debris generated when the concrete test block is crushed, thereby improving the safety of the test.

[0025] Reference Figure 1-Figure 3 , Figure 5 and Figure 8The slag processing component includes a collecting ring groove 4, which is opened on the top of the detection platform 1. A crushing groove 41 is opened in the detection platform 1, and the output end of the crushing groove 41 is tilted downward. Two groups of crushing rollers 42 are rotatably connected in the crushing groove 41. The bottom of the collecting ring groove 4 is connected to the inner cavity of the crushing groove 41, and the connection between the collecting ring groove 4 and the crushing groove 41 is located directly above the center line of the two groups of crushing rollers 42. The inner wall of the collecting ring groove 4 is set as a slope, and the inclined lower end of the slope faces the connection between the collecting ring groove 4 and the crushing groove 41, and the top outer diameter of the collecting ring groove 4 is smaller than the inner diameter of the lower shell 32. The ends of the two groups of crushing rollers 42 are connected by a gear set 421. A driving motor 43 is fixedly connected to the detection platform 1, and the output shaft of the driving motor 43 is fixed to the end of one of the crushing rollers 42. Connection: A rotating groove 5 is provided in the testing platform 1 below the pressure plate 24, and a rotating rod 51 is rotatably connected to the inner cavity of the rotating groove 5. A linkage groove 52 is provided on the testing platform 1, and a transmission shaft 53 is rotatably connected in the linkage groove 52. The transmission shaft 53 and the rotating rod 51 are connected for transmission via a first pulley set 531. A worm 54 is rotatably connected in the linkage groove 52, and a worm wheel 532 is fixedly connected to the transmission shaft 53. The worm wheel 532 and the worm 54 are meshingly connected, and the end of the worm 54 is connected for transmission to the end of the rotating shaft of the crushing roller 42 via a second pulley set 55. The bottom of the pressure plate 24 fits with the top of the testing platform 1, and a square groove 241 is provided at the center of the bottom of the pressure plate 24. A square plug block 511 is fixedly connected to the top of the rotating rod 51, and the square plug block 511 is inserted into the square groove 241.

[0026] By setting the above structure, when the driving motor 43 rotates, the second pulley group 55, the worm 54 and the worm wheel 532 and the first pulley group 531 are used to drive the rotating rod 51 to drive the pressure plate 24 to rotate, so that the surface of the pressure plate 24 generates centrifugal force. At this time, the concrete fragments accumulated on the surface of the pressure plate 24 will be thrown out, and under the cover of the encirclement formed by the upper shell 3 and the lower shell 32, they will fall into the collecting ring groove 4, and slide along the slope in the collecting ring groove 4 into the crushing groove 41, so as to realize the cleaning of the concrete fragments, so as to continue the detection of the next concrete test block, and effectively improve the detection efficiency; and when the driving motor 43 is running, under the meshing transmission of the gear group 421, the two groups of crushing rollers 42 will also be driven to rotate in the crushing groove 41, so as to crush the concrete fragments that slide into the crushing groove 41, so that they can be converted into smaller aggregate state for subsequent transportation and reuse, thereby improving the energy saving effect.

[0027] In addition, since the height of the square groove 241 is greater than the insertion depth of the square plug 511, it can ensure that the rotating rod 51 will not be subjected to vertical pressure, avoiding damage to the rotating rod 51 caused by force or deformation of the pressure plate 24, thereby ensuring the rotation effect of the pressure plate 24.

[0028] Reference Figure 5-Figure 8 The dust reduction component includes an annular groove 6, which is provided in the detection platform 1. A dust suction groove 61 is provided between the annular groove 6 and the inner cavity of the collection annular groove 4. The input end of the dust suction groove 61 is tilted downward. A filter screen 611 is provided at the input end of the dust suction groove 61. The detection platform 1 is provided with an air extraction part that delivers suction force to the annular groove 6. The air extraction part includes two groups of piston boxes 62, which are respectively fixed on both sides of the detection platform 1, and the piston boxes 62 on both sides are respectively located above the two groups of rotating wheels of the second pulley group 55. The piston boxes An upper magnetic plate 63 is slidably connected in 62, and a return spring 631 is fixedly connected between the top of the upper magnetic plate 63 and the inner wall of the piston box 62. An air flow groove 64 is provided in the testing platform 1. The top of the inner cavity of the two groups of piston boxes 62 is connected to the air flow groove 64 through an exhaust groove 641, and a one-way valve is provided in the exhaust groove 641. The air flow groove 64 is connected to the dust suction groove 61 through an exhaust pipe 642. The side walls of the two groups of rotating wheels of the second pulley group 55 are fixedly connected with the lower magnetic plate 65, and the lower magnetic plate 65 and the upper magnetic plate 63 repel each other magnetically; It should be noted that the one-way valve in the air extraction groove 641 can only allow the gas in the collecting annular groove 4 to enter the dust collection groove 61 .

[0029] Through the arrangement of the above structure, when the lower magnetic plate 65 and the upper magnetic plate 63 are separated from the repulsive area, under the rebound action of the reset spring 631, the upper magnetic plate 63 will move down and reset, thereby generating suction in the piston box 62 and opening the one-way valve in the exhaust groove 641, so that the airflow in the collecting ring groove 4 enters the airflow groove 64 along the dust suction groove 61, the annular groove 6 and the exhaust pipe 642, thereby directional guiding the dust generated by the centrifugal shaking of the concrete fragments and the dust overflowed when the concrete fragments were crushed, effectively avoiding the overflow of dust and further improving the dust reduction effect.

[0030] Reference Figure 5 , Figure 6 A water storage tank 7 is provided in the detection table 1, and a plurality of pressure spray holes 71 are provided at equal intervals between the water storage tank 7 and the top of the crushing tank 41, an exhaust groove 72 is provided between the water storage tank 7 and the air flow groove 64, a one-way valve is provided in the exhaust groove 72, a side wall of the water storage tank 7 is fixed and connected with a water injection pipe 73, and a sealing cap 731 is threadedly connected to the top of the water injection pipe 73.

[0031] It should be noted that the one-way valve in the exhaust groove 72 can only allow the gas in the air flow groove 64 to enter the water storage tank 7; in addition, the pressure nozzle 71 adopts the same structure as the existing pressure nozzle, that is, the water flow can only be sprayed out from the pressure nozzle 71 after being pressurized.

[0032] By setting the above structure, during the rotation of the second pulley group 55, the repulsive effect between the lower magnetic plate 65 and the upper magnetic plate 63 will cause the upper magnetic plate 63 to move toward the top of the inner cavity of the piston box 62, thereby compressing the gas in the piston box 62 and opening the one-way valve in the exhaust groove 72, so that the gas is filled into the water storage tank 7. As the air pressure in the water storage tank 7 increases, the internal water flow will be squeezed to spray from the pressure nozzle 71 into the crushing tank 41, thereby reducing dust on the concrete test blocks being crushed, improving the environmental quality in the detection area, reducing the friction heat generated by the two sets of crushing rollers 42, and improving the durability of the crushing rollers 42.

[0033] Among them, the telescopic end of the hydraulic cylinder 22, the pressure plate 23, the pressure plate 24, the upper shell 3, the rotating groove 5 and the center of the detection platform 1 are all on the same vertical axis, which can ensure the uniformity of pressure during detection and facilitate the cleaning of concrete fragments on the pressure plate 24.

[0034] Reference Figure 1-Figure 8 In the present invention, when in use, the concrete test block is placed on the pressure plate 24, and then the pressure plate 23 is pushed downward by the hydraulic cylinder 22, which will drive the upper shell 3 to slide downward along the guide rod 2, and finally the lower shell 32 will fit on the top of the test bench 1, and wrap around the concrete test block during the compression test to avoid the splashing of debris generated when the concrete test block is crushed, thereby improving the safety of the test. Then the pressure plate 23 will also fit on the top of the concrete test block, and then the pressure plate 23 continues to press down until the concrete test block is crushed, thereby obtaining the compressive value of the concrete test block and completing the test of the compressive performance.

[0035] After the concrete test block is crushed, the hydraulic cylinder 22 retracts slightly, so that the lower casing 32 remains in contact with the top of the test bench 1, and then the driving motor 43 rotates. The second pulley set 55, the worm 54, the worm wheel 532 and the first pulley set 531 are used to drive the rotating rod 51 to rotate the pressure plate 24, so that the surface of the pressure plate 24 generates centrifugal force. At this time, the concrete fragments accumulated on the surface of the pressure plate 24 will be thrown out and fall off under the cover of the encirclement formed by the upper casing 3 and the lower casing 32. It falls into the collecting ring groove 4 and slides along the slope in the collecting ring groove 4 into the crushing groove 41, so as to clean the concrete fragments so as to continue the inspection of the next concrete test block, which effectively improves the inspection efficiency; and when the driving motor 43 is running, under the meshing transmission action of the gear set 421, it will also drive the two sets of crushing rollers 42 to rotate in the crushing groove 41, so as to crush the concrete fragments that slide into the crushing groove 41 and convert them into smaller aggregate state for subsequent transportation and reuse, thereby improving the energy saving effect.

[0036] And during the rotation of the second pulley group 55, the repulsive effect between the lower magnetic plate 65 and the upper magnetic plate 63 will cause the upper magnetic plate 63 to move toward the top of the inner cavity of the piston box 62, thereby compressing the gas in the piston box 62 and opening the one-way valve in the exhaust groove 72, so that the gas is filled into the water storage tank 7. As the air pressure in the water storage tank 7 increases, the internal water flow will be squeezed to spray from the pressure nozzle 71 into the crushing tank 41, thereby reducing dust on the concrete test blocks being crushed, improving the environmental quality in the detection area, reducing the friction heat generated by the two sets of crushing rollers 42, and improving the durability of the crushing rollers 42. When the lower magnetic plate 65 and the upper magnetic plate 63 leave the repulsive area, under the rebound action of the reset spring 631, the upper magnetic plate 63 will move down and reset, thereby generating suction in the piston box 62 and opening the one-way valve in the exhaust groove 641, so that the airflow in the collecting ring groove 4 enters the airflow groove 64 along the dust suction groove 61, the annular groove 6 and the exhaust pipe 642, thereby guiding the dust generated by the centrifugal shaking of the concrete fragments and the dust overflowed when the concrete fragments were crushed, effectively avoiding the overflow of dust and further improving the dust reduction effect.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
