[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-5 As shown, an asphalt mixture testing device includes a frame 1, a testing box 2 fixed on the upper part of the frame 1, a first motor 3 fixed on the right outer side wall of the testing box 2, the first motor 3 being used to drive the testing component to move horizontally, the testing component being disposed inside the testing box 2, an observation door 4 being rotatably connected to the front of the testing box 2, a testing box 5 being disposed inside the testing box 2, a pad paper 6 being placed inside the testing box 5, an adjustment component being disposed at the lower part of the testing box 5, and a support component being slidably mounted on the frame 1 on the front side of the adjustment component;

[0022] The middle part of the observation door 4 is transparent glass. The asphalt mixture is placed in the test box 5. The asphalt mixture is tested by the test component. After the test is completed, the test box 5 is lowered by the adjustment component. With the cooperation of the support component, it is easy to take out the asphalt mixture and also easy to put in the asphalt mixture to be tested again. The adjustment component is reset to perform a new asphalt mixture test.

[0023] In this embodiment, the detection assembly includes a reciprocating screw 7 fixed to the output shaft of the first motor 3. A mounting plate 8 is threadedly connected to the reciprocating screw 7. Two synchronous pulleys 9 are rotatably connected to the upper part of the mounting plate 8. The two synchronous pulleys 9 are connected by a synchronous belt 10. A threaded rod 11 is fixed to the lower part of each of the two synchronous pulleys 9. The threaded rod 11 passes through the mounting plate 8. A detection plate 12 is provided below the mounting plate 8. The detection plate 12 is threadedly connected to the threaded rod 11. A detection wheel 13 is rotatably connected to the lower part of the detection plate 12. A worm gear 14 is fixed to the upper part of one of the synchronous pulleys 9. A worm 15 meshes with the worm gear 14. The worm 15 is fixed to the output shaft of the second motor 16. The second motor 16 is fixed to the upper part of the mounting plate 8. Two guide posts 17 are slidably connected to the mounting plate 8. Both ends of the two guide posts 17 are fixed to the inner wall of the detection box 2.

[0024] The second motor 16 drives the worm gear 15 to rotate, which in turn drives the worm wheel 14. The worm wheel 14, through the cooperation of the synchronous pulley 9 and the synchronous belt 10, drives the two threaded rods 11 to rotate. The threaded rods 11 move the detection plate 12. The height of the detection plate 12 is controlled by controlling the rotation direction of the second motor 16, thereby adjusting the height of the detection wheel 13. After the height of the detection wheel 13 is adjusted, the first motor 3 is controlled to drive the reciprocating screw 7 to rotate, which in turn drives the mounting plate 8 to move, so that the detection wheel 13 moves above the detection box 5 to compact the asphalt mixture for testing.

[0025] Preferably, the adjustment assembly includes a top plate 18 disposed below the detection box 5, the detection box 5 being slidably disposed on the upper part of the top plate 18, a turntable 19 being rotatably connected to the lower part of the frame 1, a first cylinder 20 and a second cylinder 21 being fixed to the left and right parts of the turntable 19 respectively, a first connecting block 22 and a second connecting block 23 being fixed to the output ends of the first cylinder 20 and the second cylinder 21 respectively, a first support block 24 being fixed to the upper part of the first connecting block 22, a second support block 25 being rotatably connected to the upper part of the second connecting block 23, the top plate 18 being fixed to the upper part of the second support block 25, the first support block 24 supporting the top plate 18, and a handle 26 being fixed to the right part of the detection box 5.

[0026] The first connecting block 22 and the second connecting block 23 are both cylindrical, the first support block 24 and the second support block 25 are both protrusions, and the front and rear connections of the protrusions are fixed with connecting plates.

[0027] In this embodiment, the support assembly includes a support frame 27 located on the front side of the frame 1. L-shaped rods 28 are fixed on both the left and right sides of the support frame 27. The two L-shaped rods 28 are slidably connected to the frame 1. Two pulleys 29 are rotatably connected to the lower part of the support frame 27. A support rod 30 is fixed on the upper part of the support frame 27. A support cylinder 31 is sleeved on the upper part of the support rod 30. A U-shaped block 32 is fixed on the upper part of the support cylinder 31. A spring 33 is provided inside the support cylinder 31. The upper end of the spring 33 is fixed to the upper part of the support cylinder 31, and the lower end of the spring 33 is fixed to the top of the support rod 30.

[0028] In this embodiment, the lower part of the support cylinder 31 is threaded with a bolt 34;

[0029] After the asphalt mixture test is completed, the first cylinder 20 and the second cylinder 21 are controlled to lower the top plate 18. When the upper side of the top plate 18 is lower than the lower side of the test box 2, the handle 26 can be pulled to rotate the turntable 19. The turntable 19 rotates the top plate 18 through the first cylinder 20 and the second cylinder 21. The first cylinder 20 and the second cylinder 21 retract to lower the top plate 18. During the descent of the top plate 18, the U-shaped block 32 will insert into the handle 26 and then pull the test box 5 outward, so that the test box 5 and the support frame 27 move together away from the frame 1. The end of the test box 5 closest to the support frame 27 sinks down, causing the second support block 25 to rotate around the second connecting block 23 and the second support. The connecting shaft of block 25 rotates, causing the end of the test box 5 and the top plate 18 near the first support block 24 to tilt upwards. The end of the test box 5 with handle 26 sinks down, pressing down the support cylinder 31 to descend, making it easier to remove the asphalt mixture. After removal, push the test box 5 upwards to make it horizontal. At this time, the support cylinder 31 is pushed back to its original position by the spring 33. Then tighten the bolt 34 to fix the support cylinder 31 to the support rod 30. At this time, the support cylinder 31 will not descend. Then add new asphalt mixture and flatten it. Push the handle 26 to push the test box 5 directly above the top plate 18. Rotate the test box 5 ninety degrees. Then control the first cylinder 20 and the second cylinder 21 to drive the test box 5 to reset and perform asphalt mixture testing.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
