[0035] When in use, first start the motor 5 to drive the threaded rod 4 to rotate, so that the moving part 7 gradually rises on the threaded rod 4 according to the guidance of the fixed column 6, so as to adjust the position between the fixed part 3 and the moving part 7 according to the length of the steel bar. When the position adjustment is completed, the two ends of the steel bar can be placed in the two clamping grooves, and then the two ends of the steel bar are clamped and fixed by the two clamping parts 8. When the steel bar is fixed, the motor 5 can be started again to drive the threaded rod 4 to rotate, at this time, the fixed part 3 and the moving part 7 are moved away from each other to stretch the clamped steel bar. When the steel bar is broken, metal debris will splash around at the fracture. At this time, the dust removal mechanism 9 can be started to operate. Through the operation of the dust removal mechanism 9, the debris can be absorbed in the first time, reducing the situation of debris splashing around and avoiding inhalation by the staff, which greatly improves the practicability of the device and also ensures the health of the staff.

[0036] Reference Figure 1 and Figure 2 The dust removal mechanism 9 includes a dust removal box 91 fixedly connected to the top of the frame 1, an exhaust fan 92 is fixedly connected to the inside of the dust removal box 91, and the air outlet of the exhaust fan 92 is located outside the dust removal box 91. A dust extraction pipe 93 is fixedly connected to the side of the dust removal box 91 away from the exhaust fan 92, and one end of the dust extraction pipe 93 is fixedly connected to a connecting shell 94. A plurality of dust extraction ports 95 are provided on one side of the connecting shell 94, and the plurality of dust extraction ports 95 are all located inside the frame 1. A slide rail 96 is symmetrically fixedly connected to the inside of the dust removal box 91, and a filter plate 97 is slidably connected to the inside of the slide rail 96. A cleaning component is installed inside the dust removal box 91, and a clamping component is installed on one side of the inside of the dust removal box 91.

[0037] When in use, first start the exhaust fan 92. When the exhaust fan 92 is running, it will generate a large suction force. The suction force generated by the exhaust fan 92 is used to draw the debris generated by the broken steel bars into the dust removal box 91 through the dust extraction port 95 and the dust extraction pipe 93. After the debris enters the dust removal box 91, the debris can be intercepted on one side of the dust removal box 91 through filtering by the filter plate 97, thereby preventing metal debris from entering the exhaust fan 92 and causing damage to the exhaust fan 92.

[0038] Reference Figure 1 and Figure 3 The cleaning component includes two slide grooves 98 symmetrically opened on the top surface of the dust removal box 91, one of the slide grooves 98 is rotatably connected to a threaded rod 2 99, one side of the dust removal box 91 is fixedly connected to a motor 2 910, the output end of the motor 2 910 is fixedly connected to one end of the threaded rod 2 99, a connecting rod 1 911 is threadedly connected to the threaded rod 2 99, a guide column 912 is fixedly connected to the other slide groove 98, a connecting rod 2 913 is fixedly connected to the guide column 912, and a scraper 914 is fixedly connected to the bottom of the connecting rod 1 911 and the connecting rod 2 913.

[0039] During use, after the debris enters the dust box 91 and is collected, the motor 2 910 can be started to drive the threaded rod 2 99 to rotate. The rotation of the threaded rod 2 99 will cause the connecting rod 1 911 to move on the threaded rod 2 99. When the connecting rod 1 911 moves, it will drive the scraper 914 at the bottom to move according to the guidance of the guide column 912. The scraper 914 can be used to push the debris collected in the dust box 91 out of the dust box 91, so as to quickly clean the inside of the dust box 91 and keep the inside of the dust box 91 clean.

[0040] Reference Figure 1 and Figure 4 The card-joint assembly includes a groove symmetrically opened on one side of the dust removal box 91, a card block 915 is slidably connected inside the groove, a spring 916 is fixedly connected inside the groove, one end of the spring 916 is fixedly connected to the card block 915, one end of the card block 915 is arc-shaped, a sealing door 917 is hinged on one side of the dust removal box 91, and a card slot 918 is symmetrically opened on one side of the sealing door 917, and the card slot 918 is consistent in size with the arc-shaped end of the card block 915.

[0041] When in use, first close the sealing door 917 so that the sealing door 917 seals one side of the dust removal box 91 to prevent metal debris from entering the dust removal box 91 and then floating outward. When the sealing door 917 is closed, one side of the sealing door 917 will squeeze the arc-shaped end of the block 915 to push the block 915 into the groove. When the sealing door 917 is completely closed, the block 915 will be pushed into the interior of the slot 918 according to the rebound of the spring 916. In this way, the sealing door 917 is limited and fixed through the cooperation between the block 915 and the slot 918 to prevent the sealing door 917 from opening automatically during the operation of the equipment. When the inside of the dust removal box 91 needs to be cleaned, the sealing door 917 can be pulled open to separate the block 915 from the slot 918, and the sealing door 917 can be opened.

[0042] The implementation principle of the dust removal device for steel bar tensile test in this embodiment is as follows: when in use, first start the motor 5 to drive the threaded rod 4 to rotate, so that the movable part 7 gradually rises on the threaded rod 4 according to the guidance of the fixed column 6, so as to adjust the position between the fixed part 3 and the movable part 7 according to the length of the steel bar. When the position adjustment is completed, the two ends of the steel bar can be placed in the two clamping grooves, and then the two ends of the steel bar are clamped and fixed by the two clamping parts 8. When the steel bar is fixed, the motor 5 can be started again to drive the threaded rod 4 to rotate, at this time, the fixed part 3 and the movable part 7 are moved away from each other to stretch the clamped steel bar. When the steel bar is broken, metal debris will fly around at the fracture. At this time, the sealing door 917 can be closed first, so that the sealing door 917 can seal one side of the dust removal box 91 to prevent metal debris from entering the dust removal box 91 and then floating outward. When the sealing door 917 is closed, one side of the sealing door 917 will squeeze the arc end of the card block 915 to push the card block 915 into the groove. When the sealing door 917 is completely closed, the card block 915 will be pushed into the inside of the card slot 918 according to the rebound of the spring 916. In this way, the sealing door 917 is limited and fixed by the cooperation of the card block 915 and the card slot 918 to prevent the sealing door 917 from automatically opening during the operation of the equipment.

[0043] Secondly, the exhaust fan 92 is started to operate. When the exhaust fan 92 is running, a large suction force is generated. The suction force generated by the exhaust fan 92 is used to draw the debris generated by the broken steel bar through the dust extraction port 95 and the dust extraction pipe 93 to the inside of the dust removal box 91. When the debris enters the dust removal box 91, the debris can be intercepted on one side of the dust removal box 91 through the filtration of the filter plate 97, thereby preventing metal debris from entering the exhaust fan 92 and causing damage to the exhaust fan 92. In this way, the debris can be absorbed in the first time, reducing the situation where the debris splashes around and preventing the staff from inhaling it, which greatly improves the practicality of the device and also ensures the health of the staff.

[0044] In addition, after the debris enters the dust removal box 91 and is collected, the sealing door 917 can be pulled open to separate the block 915 from the slot 918, and the sealing door 917 can be opened. Then the motor 2 910 can be started to drive the threaded rod 2 99 to rotate. The rotation of the threaded rod 2 99 will cause the connecting rod 1 911 to move on the threaded rod 2 99. When the connecting rod 1 911 moves, it will drive the scraper 914 at the bottom to move according to the guidance of the guide column 912. The scraper 914 can be used to push the debris collected in the dust removal box 91 out of the dust removal box 91, so as to quickly clean the inside of the dust removal box 91 and keep the inside of the dust removal box 91 clean.
