This patent can grind the top surface of the concrete block into a circular wear area, eliminating the grinding dead angle to the greatest extent, enabling a comprehensive observation of the wear condition of the top surface of the concrete block, and improving the accuracy of the detection results. However, there is still a problem that different positions of a single piece of material may affect the test results. Therefore, a wear resistance detection device for building materials is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a wear resistance detection device for building materials in view of the above deficiencies in the prior art.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is: a wear resistance detection device for building materials, including a bottom frame, the inner side of the top end of the bottom frame is fixedly connected with a table board, the top end of the bottom frame is fixedly connected with a support frame, the top end of the support frame is fixedly connected with a top board, and a detection mechanism is arranged below the top board; The detection mechanism includes a threaded rod, on the outer surface of which is threadedly connected a lifting guide plate. The front end of the lifting guide plate is fixedly connected with a pressing frame. The bottom surface of the pressing frame is fixedly connected with a bottom support plate. The top surface of the bottom support plate is fixedly connected with a pressing cover plate. The bottom surface of the pressing cover plate is fixedly connected with a fixed seat. Inside the fixed seat is fixedly connected an induction module. Directly below the induction module is arranged a laser emission module. On the side of the laser emission module is fixedly connected a driving end. At the bottom end of the output shaft of the driving end is fixedly connected a grinding wheel.

[0006] According to the above technical solution, on the outer surface of the driving end is fixedly connected a pressure cylinder. At the top end of the bottom support plate is fixedly connected a telescopic rod. On the bottom surface of the top plate are fixedly connected four vertical guide rods.

[0007] According to the above technical solution, the threaded rod is rotationally connected with the table board and the top plate. The pressure cylinder is slidably connected with the bottom support plate. The top end of the telescopic rod is fixedly connected with the fixed seat. Between the fixed seat and the driving end is arranged a return spring, and the two ends of the return spring are respectively fixedly connected with the fixed seat and the driving end. The vertical guide rods are slidably connected with the pressing cover plate. The external motor on the motor base drives the connected threaded rod to rotate. The rotation makes the lifting guide plate outside the threaded rod move upward or downward along the thread. When the lifting guide plate moves downward, the lifting guide plate will drive the connected pressing frame to move downward. The pressing cover plate fixed by the pressing frame will slide downward along the vertical guide rods connected to the bottom surface of the top plate. The downward movement of the pressing cover plate will drive the fixed seat to approach the lower table board and make the grinding wheel press against the test plate. At this time, the grinding wheel receives the reverse acting force from the test plate and drives the pressure cylinder through the driving end to push the telescopic rod to contract and compress the return spring. The pressure cylinder is pushed by the telescopic rod connected to the fixed seat, so that the driving end installed in the pressure cylinder is in a working state. The output shaft connected to the driving end drives the grinding wheel. After the grinding wheel has rubbed the test plate for a standard unit time, a worn area will be formed on the surface of the test plate. At this time, the return spring pushes the pressure cylinder to make the grinding wheel approach the worn area, and the displacement amount of the laser emission module descending is detected by the induction module on the fixed seat. The depth of wear prevention of the test plate is obtained through the displacement amount, and the correction parameters are input by combining the test time and the observation of the wear area uniformity. The wear parameter is obtained through calculation. The obtained wear parameter is compared with the equidistant value of the wear output to judge the wear resistance of the whole detection.

[0008] According to the above technical solution, the positioning mechanism includes a telescopic end. Inside the telescopic end is slidably connected an elastic pressing rod. The bottom surface of the elastic pressing rod is fixedly connected with a descending frame. Directly below the descending frame are arranged two downward pressing folding plates. The bottom end of the downward pressing folding plate is rotationally connected with a slider. The outer surface of the downward pressing folding plate is slidably connected with a chute strip. The bottom surface of the table board is fixedly connected with a chute support frame. On the side of the chute strip is fixedly connected a filtering baffle.

[0009] According to the above technical solution, the downward pressure folding plate is slidably connected to the table plate, and two slide plate grooves are opened on the upper surface of the table plate, the slide plate bar is slidably connected to the slide plate groove, the slide plate support frame is slidably connected to the slider, a rigid spring is arranged inside the telescopic end, and the two ends of the rigid spring are respectively fixedly connected to the telescopic end and the elastic pressure rod, when the downward pressure frame moves downward, the downward pressure frame will drive the connected telescopic end to move downward, and the elastic pressure rod is pushed by the rigid spring built into the telescopic end, so that the elastic pressure rod pushes the descending frame to apply pressure to the downward pressure folding plate, and the downward pressure folding plate will be pressed to push the slider downward to slide downward along the slide plate support frame and move toward the center of the table plate. When the two sides of the test plate are close to each other, the downward pressure folding plate will move downward along the slide groove bar, and the slide groove bar will move along the slide plate groove opened on the table plate under the drive of the downward pressure folding plate. When the downward pressure folding plate stops moving, the downward pressure frame continues to press down, allowing the descending frame to push the elastic pressure rod in the opposite direction to squeeze the rigid spring in the telescopic end. At this time, the grinding wheel just contacts the surface of the test plate, and the downward pressure folding plates on both sides are approached to each other and pressed downward, so that the plate is clamped between the table plate and the downward pressure folding plate. At the same time, the contact area of ​​the edge of the plate is increased by pressing down, so as to avoid vibration caused by the detection, which may cause the plate to deviate from its original position and affect the test results. In addition, the filter baffle moves through the slide groove bar.

[0010] According to the above technical scheme, the collecting mechanism includes a collecting trough end, a telescopic folding rod is fixedly connected to the side of the collecting trough end, an end of the telescopic folding rod away from the collecting trough end is slidably connected to a top rod, an end of the top rod away from the telescopic folding rod is slidably connected to an inclined groove guide plate, a linkage column is fixedly connected to the side of the inclined groove guide plate, an end of the linkage column away from the inclined groove guide plate is fixedly connected to an exhaust duct, the top of the exhaust duct is fixedly connected to an air duct plate, both sides of the top of the exhaust duct are fixedly connected to a filter screen, elastic scrapers are arranged on the sides of the filter screen, the outer side of the exhaust duct is slidably connected to a positioning groove end, and the bottom surface of the exhaust duct is fixedly connected to a suction and pressure port.

[0011] The collecting slot end is fixedly connected to the slide slot bar, the telescopic folding rod is provided with a built-in spring inside, and the two ends of the built-in spring are respectively fixedly connected to the telescopic folding rod and the push rod, the positioning slot end is slidably connected to the collecting slot end, the elastic scraper is fixedly connected to the positioning slot end, an elastic spring is provided between the bottom surface of the exhaust duct and the bottom surface of the positioning slot end, and the two ends of the elastic spring are respectively fixedly connected to the exhaust duct and the positioning slot end. When the detection plate is placed above the air duct plate, the downward pressing folding plate movement drives the connected collecting slot end to move through the connected slide slot bar. The movement of the collecting slot end will push the built-in spring in the telescopic folding rod to push the push rod, and the inclined slot guide plate is pushed by the push rod. At this time, the inclined slot guide plate drives the exhaust duct to slide downward along the positioning slot end through the linkage column and stretches the reciprocating spring. At this time, the exhaust duct drives the top surface of the air duct plate to drop to the same height as the filter baffle, and the air duct plate is now aligned with the positioning slot end The interior is connected, and air is extracted through the suction and pressure port, so that the particulate dust generated by the test board during the test will flow with the air through the filter baffle into the collecting slot end, and then be sucked into the air duct plate in the positioning slot end through the collecting slot end. At this time, the particulate matter will be blocked on the outside of the filter, and the air will be discharged from the bottom suction and pressure port after entering the exhaust duct. When the descending frame is reset upward and no longer presses on the downward pressure folding plate, the air duct plate is reset through the above steps and extends upward from the inside of the positioning slot end. At this time, the side of the air duct plate faces the table plane, and the particles scattered on the table plane are sucked into the air duct plate through the air duct plate, and fall into the positioning slot end through the air duct plate for collection, so as to avoid the material residues and particulate matter scattered on the table affecting the placement of the test plate and affecting the test results. At the same time, the air duct plate is switched to be connected to the collection slot end structure, so as to collect the particulate dust generated during the test.

[0012] The present invention adopts the above technical solution to bring the following beneficial effects: 1. The wear-resistant testing equipment for building materials detects the displacement of the laser emission module through the sensing module on the fixed seat, and obtains the depth of the test plate to avoid wear through the displacement. It inputs correction parameters in combination with the test time and the observation of the uniformity of the wear area, and obtains the wear parameters through calculation. The wear parameters obtained are compared with the equidistant values ​​of the wear output to judge the overall wear resistance of the test. At the same time, multiple groups of test data for the same plate can avoid the hardness of different parts of the same plate being affected by temperature or humidity during the production process, which affects the test results. The data obtained through testing can be averaged by removing the highest and lowest values ​​to improve the accuracy of the test results.

[0013] 2. The wear-resistant testing equipment for building materials increases the contact area at the edge of the plate by pressing down, avoiding vibration during testing that may cause the plate to deviate from its original position and affect the test results. In addition, the filter baffle moves through the chute bar, shaking the debris that has fallen onto the filter baffle into the upper holes and collecting it through the holes below, preventing the debris from remaining above the filter baffle and affecting the balance of the test plate placement, and reducing the test interference caused by debris when placing the plate.

[0014] 3. The wear-resistant testing equipment for building materials prevents the residual material residues and particulate matter scattered on the table board from affecting the placement of the test plate and thus the test results. At the same time, by using the air duct plate to switch and connect with the collection trough end structure, it can collect the generated particulate dust during the test, preventing the particulate matter from floating outwards with the air and polluting the environment. In addition, when the air duct plate descends, the filter net connected to the air duct plate will move relative to the elastic scraper, and the dust attached to the filter net will be cleaned and scraped off by the elastic scraper, causing the dust to fall into the positioning trough end for collection, improving the filtering effect of the filter net during long-term use.

Detailed implementation manners

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1 - 9 , an embodiment of the present invention is: a wear-resistant detection device for building materials, including a bottom frame 1, a table board 2 is fixedly connected to the inner side of the top end of the bottom frame 1, a support frame 3 is fixedly connected to the top end of the bottom frame 1, a top board 4 is fixedly connected to the top end of the support frame 3, and a detection mechanism 5 is arranged below the top board 4; The detection mechanism 5 includes a threaded rod 51. A lifting guide plate 53 is threadedly connected to the outer surface of the threaded rod 51. A pressing frame 54 is fixedly connected to the front end of the lifting guide plate 53. A bottom support plate 56 is fixedly connected to the bottom surface of the pressing frame 54. A pressing cover plate 55 is fixedly connected to the top surface of the bottom support plate 56. A fixing seat 512 is fixedly connected to the bottom surface of the pressing cover plate 55. An induction module 513 is fixedly connected inside the fixing seat 512. A laser emission module 511 is arranged directly below the induction module 513. A driving end 58 is fixedly connected to the side of the laser emission module 511. A grinding wheel 510 is fixedly connected to the bottom end of the output shaft of the driving end 58. A pressing cylinder 57 is fixedly connected to the outer surface of the driving end 58. A telescopic rod 59 is fixedly connected to the top end of the bottom support plate 56. Four vertical guide rods 514 are fixedly connected to the bottom surface of the top plate 4. The threaded rod 51 is rotatably connected to the table plate 2, and the threaded rod 51 is rotatably connected to the top plate 4. The pressing cylinder 57 is slidably connected to the bottom support plate 56. The top end of the telescopic rod 59 is fixedly connected to the fixing seat 512. A return spring is arranged between the fixing seat 512 and the driving end 58, and the two ends of the return spring are respectively fixedly connected to the fixing seat 512 and the driving end 58. The vertical guide rods 514 are slidably connected to the pressing cover plate 55. The external motor on the motor seat 52 drives the connected threaded rod 51 to rotate. The rotation makes the lifting guide plate 53 outside the threaded rod 51 move upward or downward along the thread. When the lifting guide plate 53 moves downward, the lifting guide plate 53 will drive the connected pressing frame 54 to move downward. The pressing cover plate 55 fixed to the pressing frame 54 will slide downward along the vertical guide rods 514 connected to the bottom surface of the top plate 4. The downward movement of the pressing cover plate 55 will drive the fixing seat 512 to approach the lower table plate 2 and make the grinding wheel 510 press against the test plate. At this time, the grinding wheel 510 receives the reverse force from the test plate and drives the pressing cylinder 57 to push the telescopic rod 59 to contract and compress the return spring through the driving end 58. The pressing cylinder 57 is pushed by the telescopic rod 59 connected to the fixing seat 512, so that the driving end 58 installed in the pressing cylinder 57 is in a working state. The grinding wheel 510 is driven by the output shaft connected to the driving end 58. After the grinding wheel 510 rubs the test plate for a standard unit time, a worn area will be formed on the surface of the test plate. At this time, the return spring pushes the pressing cylinder 57 to make the grinding wheel 510 approach the worn area, and the displacement amount of the laser emission module 511 descending is detected by the induction module 513 on the fixing seat 512. The depth of wear prevention of the test plate is obtained through the displacement amount, and the correction parameters are input by combining the test time and the observation of the wear area uniformity. The wear parameter is obtained through calculation. The obtained wear parameter is compared with the equidistant value of the wear output to judge the overall wear resistance of the detection. At the same time, the test data of multiple groups of detections on the same plate can avoid the influence of different hardnesses of different parts of the same plate on the test results due to temperature or humidity during the production process. By removing the highest and lowest values from the detected data and taking the average value, the accuracy of the detection results can be improved.

[0019] The positioning mechanism 6 includes a telescopic end 61. An elastic pressure rod 62 is slidably connected inside the telescopic end 61. A bottom surface of the elastic pressure rod 62 is fixedly connected to a descending frame 63. There are two downward pressing folding plates 64 arranged directly below the descending frame 63. A bottom end of the downward pressing folding plate 64 is rotatably connected to a slider 66. An outer surface of the downward pressing folding plate 64 is slidably connected to a chute bar 65. A chute support 67 is fixedly connected to a bottom surface of the table board 2. A filter baffle 68 is fixedly connected to a side surface of the chute bar 65. The downward pressing folding plate 64 is slidably connected to the table board 2. There are two slide plate grooves formed on an upper surface of the table board 2. The chute bar 65 is slidably connected to the slide plate grooves. The chute support 67 is slidably connected to the slider 66. A rigid spring is arranged inside the telescopic end 61, and two ends of the rigid spring are respectively fixedly connected to the telescopic end 61 and the elastic pressure rod 62. When the downward pressing frame 54 moves downward, the downward pressing frame 54 drives the connected telescopic end 61 to move downward. The rigid spring built in the telescopic end 61 is used to push the elastic pressure rod 62, so that the elastic pressure rod 62 pushes the descending frame 63 to apply pressure to the downward pressing folding plate 64. When the downward pressing folding plate 64 is pressured, it will push the slider 66 downward along the chute support 67 and move closer to the middle of the table board 2 at the same time. When the downward pressing folding plate 64 moves downward, it will slide downward along the chute bar 65. Driven by the downward pressing folding plate 64, the chute bar 65 will move along the slide plate grooves formed on the table board 2. When the downward pressing folding plate 64 stops moving, the downward pressing frame 54 continues to press downward, so that the descending frame 63 pushes the elastic pressure rod 62 in the reverse direction to squeeze the rigid spring inside the telescopic end 61. At this time, the grinding wheel 510 just contacts the surface of the test plate. By the two downward pressing folding plates 64 moving closer to each other and pressing downward, the plate is clamped between the table board 2 and the downward pressing folding plate 64. At the same time, by pressing downward, the contact area at the edge of the plate is increased, so as to avoid vibration during the test causing the plate to deviate from its original position and affecting the test results. In addition, the filter baffle 68 connected by the chute bar 65 moves, shakes the debris falling on the filter baffle 68 into the upper holes, and the debris falls into the lower part through the holes and is collected, so as to avoid the debris remaining above the filter baffle 68 and affecting the balance of the placement of the test plate, and reducing the test interference caused by the debris when placing the plate.

[0020] The collection mechanism 7 includes a collection trough end 71. A telescopic folding rod 72 is fixedly connected to the side of the collection trough end 71. One end of the telescopic folding rod 72 away from the collection trough end 71 is slidably connected to a push rod 73. One end of the push rod 73 away from the telescopic folding rod 72 is slidably connected to an inclined groove guide plate 74. A linkage column 75 is fixedly connected to the side of the inclined groove guide plate 74. One end of the linkage column 75 away from the inclined groove guide plate 74 is fixedly connected to an air extraction duct 76. The top end of the air extraction duct 76 is fixedly connected to an air duct plate 77. Two sides of the top end of the air extraction duct 76 are fixedly connected to a filter screen 78. An elastic scraper 79 is arranged on the side of the filter screen 78. The outer side of the air extraction duct 76 is slidably connected to a positioning groove end 710. The bottom surface of the air extraction duct 76 is fixedly connected to an air extraction and pressure port 711. The collection trough end 71 is fixedly connected to a chute strip 65. An internal spring is arranged inside the telescopic folding rod 72, and both ends of the internal spring are fixedly connected to the telescopic folding rod 72 and the push rod 73 respectively. The positioning groove end 710 is slidably connected to the collection trough end 71. The elastic scraper 79 is fixedly connected to the positioning groove end 710. A resilient spring is arranged between the bottom surface of the air extraction duct 76 and the bottom surface of the positioning groove end 710, and both ends of the resilient spring are fixedly connected to the air extraction duct 76 and the positioning groove end 710 respectively. When a test plate is placed above the air duct plate 77, the downward movement of the pressing folding plate 64 drives the connected collection trough end 71 to move through the connected chute strip 65. The movement of the collection trough end 71 will push the internal spring inside the telescopic folding rod 72 to push the push rod 73. The push rod 73 is used to push the inclined groove guide plate 74. At this time, the inclined groove guide plate 74 drives the air extraction duct 76 to slide downward along the positioning groove end 710 through the linkage column 75 and stretch the reciprocating spring. At this time, the air extraction duct 76 drives the top surface of the air duct plate 77 to drop to the same height as the filter baffle 68. At this time, the air duct plate 77 is internally connected to the positioning groove end 710. Air is extracted through the air extraction and pressure port 711, so that the particulate dust generated by the test plate during the test flows through the filter baffle 68 with the air flow and enters the collection trough end 71, and then is inhaled into the air duct plate 77 inside the positioning groove end 710 through the collection trough end 71. At this time, the particulate matter will be blocked outside the filter screen 78, and the air enters the air extraction duct 76 and is discharged from the bottom air extraction and pressure port 711. When the lowering frame 63 resets upward and no longer exerts pressure on the pressing folding plate 64, at this time, the air duct plate 77 extends upward from the inside of the positioning groove end 710 through the above steps. At this time, the side of the air duct plate 77 faces the plane of the table board 2. The particulate matter scattered on the plane of the table board 2 will be sucked into the air duct plate 77 by the air duct plate 77, and falls into the positioning groove end 710 through the air duct plate 77 for collection, avoiding the residual material residues and particulate matter scattered on the table board 2 from affecting the placement of the test plate and thus affecting the test results. At the same time, by using the air duct plate 77 to switch the structure connected to the collection trough end 71, the particulate dust generated during the test can be collected, avoiding the particulate matter from floating out with the air and polluting the environment. In addition, when the air duct plate 77 descends, the filter screen 78 connected to the air duct plate 77 will move relative to the elastic scraper 79, and the dust attached to the filter screen 78 will be cleaned and scraped off by the elastic scraper 79, so that the dust falls into the positioning groove end 710 for collection.Improve the filtering effect of the filter screen 78 during long-term use.

[0021] Working principle: The external motor on the motor base 52 drives the connected threaded rod 51 to rotate. The rotation causes the lifting guide plate 53 outside the threaded rod 51 to move upward or downward along the thread. When the lifting guide plate 53 moves downward, the lifting guide plate 53 drives the connected downward pressure frame 54 to move downward. The pressure cover plate 55 fixed to the downward pressure frame 54 slides downward along the vertical guide rod 514 connected to the bottom surface of the top plate 4. The downward movement of the pressure cover plate 55 drives the fixed seat 512 to approach the lower platen 2, and makes the grinding wheel 510 press against the test plate. At this time, the grinding wheel 510 receives the reverse force from the test plate and drives the pressure cylinder 57 to push the telescopic rod 59 to contract and compress the return spring through the driving end 58. The telescopic rod 59 connected to the fixed seat 512 pushes the pressure cylinder 57, so that the driving end 58 installed in the pressure cylinder 57 is in a working state. The output shaft connected to the driving end 58 drives the grinding wheel 510. After the grinding wheel 510 frictions the test plate for a standard unit time, a worn area will be formed on the surface of the test plate. At this time, the return spring pushes the pressure cylinder 57 to make the grinding wheel 510 approach the worn area, and the displacement amount of the laser emission module 511 descending is detected by the induction module 513 on the fixed seat 512. The depth of the test plate to avoid wear is obtained through the displacement amount, and the correction parameters are input by combining the test time and the observation of the uniformity of the worn area. The wear parameter is obtained through calculation. The obtained wear parameter is compared with the equidistant value of the wear output to judge the overall wear resistance of the detection. At the same time, the test data of multiple groups of tests on the same plate can avoid the influence of different hardnesses of different parts of the same plate on the test results due to temperature or humidity during the production process. By removing the highest and lowest values and taking the average of the detected data, the accuracy of the test results can be improved; When the pressing frame 54 moves downward, the pressing frame 54 will drive the connected telescopic end 61 to move downward. The rigid spring built into the telescopic end 61 pushes the elastic pressure rod 62, causing the elastic pressure rod 62 to push the descending frame 63 to press on the downward folding plate 64. When the downward folding plate 64 is pressed, it will push the slider 66 downward along the chute support 67 while moving closer to the middle of the table board 2. The downward movement of the downward folding plate 64 will slide downward along the chute bar 65. Driven by the downward folding plate 64, the chute bar 65 will move along the slide groove opened on the table board 2. When the downward folding plate 64 stops moving, the pressing frame 54 continues to press downward, causing the descending frame 63 to push the elastic pressure rod 62 in the opposite direction to squeeze the rigid spring in the telescopic end 61. At this time, the grinding wheel 510 just contacts the surface of the test plate. By pressing on the two sides of the downward folding plate 64 to move closer and downward, the plate is clamped between the table board 2 and the downward folding plate 64. At the same time, by pressing down, the contact area at the edge of the plate is increased to prevent the test from vibrating and causing the plate to deviate from its original position, which affects the test results. In addition, the filter baffle 68 connected by the chute bar 65 moves, shaking the debris that has fallen on the filter baffle 68 into the upper hole and collecting it through the hole to avoid the debris remaining above the filter baffle 68 and affecting the balance of the test plate placement, reducing the test interference caused by the debris when placing the plate; When placing the test plate above the air duct plate 77, pressing down the folding plate 64 causes the connected chute bar 65 to drive the movement of the connected collecting trough end 71. The movement of the collecting trough end 71 will push the built-in spring inside the telescopic folding rod 72 to push the ejector rod 73, and the ejector rod 73 will push the inclined chute guide plate 74. At this time, the inclined chute guide plate 74 drives the air extraction duct 76 to slide downward along the positioning trough end 710 through the linkage column 75 and stretch the reciprocating spring. At this time, the air extraction duct 76 drives the top surface of the air duct plate 77 to drop to the same height as the filter baffle 68. At this time, the air duct plate 77 is internally connected to the positioning trough end 710. By pumping air through the pumping port 711, the particulate dust generated by the test plate during the test will flow through the filter baffle 68 with the air flow and enter the collecting trough end 71, and then be sucked into the air duct plate 77 inside the positioning trough end 710. At this time, the particulate matter will be blocked outside the filter net 78, and the air enters the air extraction duct 76 and is discharged from the bottom pumping port 711. When the descending frame 63 resets upward and no longer presses on the pressing folding plate 64, at this time, the air duct plate 77 extends upward from the inside of the positioning trough end 710 through the above steps. At this time, the side of the air duct plate 77 faces the plane of the table board 2. The particulate matter scattered on the plane of the table board 2 will be sucked into the air duct plate 77 by suction, and fall into the positioning trough end 710 through the air duct plate 77 for collection, avoiding the influence of the residual material residues and particulate matter scattered on the table board 2 on the placement of the test plate and affecting the test results. At the same time, by using the air duct plate 77 to switch the structure connected to the collecting trough end 71, the particulate dust generated during the test can be collected, avoiding the particulate matter from floating outwards with the air and polluting the environment. In addition, when the air duct plate 77 descends, the filter net 78 connected to the air duct plate 77 will move relative to the elastic scraper 79, and the dust attached to the filter net 78 will be cleaned and scraped off by the elastic scraper 79, so that the dust falls into the positioning trough end 710 for collection, improving the filtering effect of the filter net 78 during long-term use.
