[0039] A trapezoidal block 35 is slidably connected to the inner wall of the square box 30. Due to the restriction of the square box 30, the trapezoidal block 35 can slide vertically up and down. Reset components for resetting the trapezoidal block 35 are fixedly connected to both the left and right sides of the trapezoidal block 35. The reset components include side plates 37. The adjacent sides of the two side plates 37 are respectively fixedly connected to the left and right sides of the trapezoidal block 35 to restrict the side plates 37. A strong spring 38 is fixedly connected to the bottom side of the side plate 37 to fixedly restrict the strong spring 38 so that the strong spring 38 can be evenly stressed. A triangular opening 36 is formed at the front end of the trapezoidal block 35. The inner wall of the trapezoidal block 35 is slidably connected to the rear end of the sliding shaft 33. An electric push rod 39 is fixedly connected to the inner wall of the middle part of the test plate 1. A top plate 40 is fixedly connected to the driving end of the electric push rod 39. By fixing the electric push rod 39, the electric push rod 39 can push the top plate 40 upward to eject the item.
[0040] Working principle: We place the item to be subjected to the loading test on the ejector plate 40, and then drive the second motor 13 to drive the rotating shaft 14 to rotate, thereby driving the gear 15 to rotate, and then driving the engaged sliding column 16 to slide. When rotating clockwise, it will drive the sliding column 16 to slide towards the first motor 8. The sliding column 16 drives the I-shaped plate 18 to slide towards the first motor 8, thereby pushing the two rotating plates 19 to rotate and pushing the two concave blocks 20 to slide towards the side away from the sliding column 16, and then driving the two clamping plates 21 to slide towards the side away from the sliding column 16, so that the two clamping plates 21 expand to clamp the item for the loading test between the two clamping plates 21. At this time, reverse-start the second motor 13, which is the opposite of the forward rotation, so that the two clamping plates 21 can slide towards the adjacent side to fix the item for the loading test;
[0041] Then, drive the cylinder 4 to push the pressure plate 5 to press the item for the loading test, so that the item for the loading test can be subjected to the loading test. After this test, reverse the second motor 13 so that the two clamping plates 21 no longer drive the item for the loading test. Then, drive the electric push rod 39 to push the ejector plate 40 upward, and then push the item for the loading test upward. At this time, drive the second motor 13 to drive the subsequent components to rotate clockwise, so that the two clamping plates 21 can fix the item for the loading test. Then, drive the electric push rod 39 to drive the ejector plate 40 downward, so that the item for the loading test is suspended. Then, drive the first motor 8 to drive the rotating shaft 9 to rotate, and then drive the opening frame 10 to rotate. After the opening frame 10 rotates to 90 degrees, the height of the opening frame 10 will not contact the test plate 1, so that the item for the loading test fixed by the clamping plates 21 inside the opening frame 10 can be flipped, so that the item for the loading test can be subjected to the loading test at different angles, thereby improving the functionality of the device;
[0042] After the item for the loading test has been subjected to the loading test, it will deform or break, and the dropped parts or damaged components. Then, drive the hydraulic cylinder 31 to push the push plate 32 to slide, and then push the test plate 1 and the damaged item for the loading test forward together. Then, it will fall into the inside of the sliding frame 26 and be supported by the chemical screening plate 27. Then, as the push plate 32 slides away from the top side of the trapezoidal block 35, the trapezoidal block 35 will be pushed upward by the thrust provided by the strong spring 38 to the side plate 37. Then, it will push the sliding shaft 33 forward, and then push the rubber plate 34 to strike the force-bearing plate 28. Then, the force-bearing plate 28 will transmit the vibrating force to the screening plate 27, so that the broken item for the loading test on the top of the screening plate 27 is vibrated, so that the larger items remain on the screening plate 27, and the smaller items will pass through the screening plate 27 and fall into the inside of the collection box 29, enabling it to quickly separate the broken items after the test without manual separation, thereby improving the subsequent work efficiency.
[0043] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features.
