These laboratory-grade viscometers have inherent limitations and cannot meet the needs of rapid and immediate testing of asphalt quality at construction sites. Some existing traditional rapid asphalt testing devices are also not suitable for the harsh environment of heavy dust at construction sites due to the lack of dustproof configuration, and the test results will be biased due to the harsh environment, making them impractical.

[0015] 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.

[0016] Reference Figure 1 The present invention provides an embodiment of an asphalt viscosity testing device, including a positioning insert 4. The positioning insert 4 can help ensure that the falling height of the gravity ball 34 is consistent during each test, so that some variables are uniform. A testing component 3 is provided on the left side of the positioning insert 4. The testing component 3 can quickly and roughly test the viscosity of asphalt.

[0017] Reference Figure 2 - Figure 3 The detection component 3 includes an inner cylinder 31, which separates the insulation liquid from the asphalt sample to be tested. An anti-adhesion layer 32 is fixedly connected to the inner wall of the inner cylinder 31, preventing asphalt from sticking inside and facilitating faster cleaning. Six auxiliary blocks 33 are connected to the bottom of the inner cylinder 31 and the anti-adhesion layer 32. These six auxiliary blocks 33 assist the push rod 35 in limiting the gravity ball 34. The gravity ball 34 is slidably connected to the outside of the six auxiliary blocks 33. The gravity ball 34 uses the resistance of the asphalt against the gravity ball 34 to more easily qualitatively convert the viscosity of the asphalt sample. A cylindrical cavity is formed in the middle of the six auxiliary blocks 33, providing a space for the push rod 35 to be inserted and withdrawn. The push rod 35 is inserted into the cylindrical cavity formed in the middle of the six auxiliary blocks 33. 5. The push rod 35 has a scale to measure the falling distance of the gravity ball 34. The lower part of the push rod 35 is frustum-shaped, and the bottom of the frustum-shaped bottom can help the push rod 35 to be inserted into the cylindrical cavity. The detection component 3 is equipped with a heat insulation cylinder 2. Hot water can be added between the heat insulation cylinder 2 and the inner cylinder 31 to keep it warm, and the heat insulation cylinder 2 can continuously heat and maintain the water temperature. The lower side of the inside of the heat insulation cylinder 2 is provided with a second installation groove 21. The second installation groove 21 is used to fix the inner cylinder 31. The inside of the second installation groove 21 is movably connected to the inner cylinder 31 to facilitate cleaning of the inner cylinder 31. The lower part of the heat insulation cylinder 2 is fixedly connected with a fixing block 22. The fixing block 22 assists the first installation groove 123 in fixing the heat insulation cylinder 2. The detection component 3 is equipped with a dustproof component 1. The dustproof component 1 can prevent dust from the construction site during the test from entering the asphalt sample to be tested.

[0018] Reference Figure 4The dustproof component 1 is made of transparent material, which allows for constant observation of the detection process and subsequent readings. The dustproof component 1 includes a dustproof cover 11, with an insertion hole 111 in the middle of the dustproof cover 11. The insertion hole 111 can assist in the insertion and removal of the push rod 35. The push rod 35 is movably connected to the insertion hole 111. An installation block 112 is fixedly connected to the lower part of the dustproof cover 11. The installation block 112 assists in the disassembly and assembly of the dustproof component 1.

[0019] Reference Figure 1 - Figure 3 The dustproof assembly 1 also includes a dustproof cylinder 12. An auxiliary groove 121 is provided on the upper part of the dustproof cylinder 12. The auxiliary groove 121 corresponds to the mounting block 112 to facilitate the assembly of the dustproof cover 11 and the dustproof cylinder 12. The mounting block 112 is engaged with the auxiliary groove 121. A first mounting groove 123 is provided on the upper side of the bottom of the dustproof cylinder 12. The first mounting groove 123 fixes the dustproof cylinder 12 and the insulation cylinder 2. The first mounting groove 123 is engaged with the fixing block 22. A positioning groove 122 is provided on the upper part of the dustproof assembly 1. The positioning insert 4 is movably connected to the positioning groove 122. The positioning slot 122 can accurately insert the positioning insert 4 into the designated position to block the fall of the gravity ball 34 when the detection has not started. The upper part of the positioning insert 4 is movably connected to the lower part of the dust cover 11. The left side of the positioning insert 4 abuts against the outside of part of the auxiliary block 33. The pulling of the positioning insert 4 meets the actual falling height of the gravity ball 34 and unifies other influencing variables. The upper part of the positioning insert 4 contacts the lower part of the gravity ball 34. The upper part of the push rod 35 is fixedly connected to the push-pull ring 36. The push-pull ring 36 can make it easier for the operator to push and pull the push rod 35.

[0020] Working principle: When testing is required, open the dust cover 11 to detach the mounting block 112 from the auxiliary groove 121. Pull up the push rod 35 to remove the dust cover 11 and the gravity ball 34. Pour an appropriate amount of hot water into the space between the insulation cylinder 2 and the inner cylinder 31. Pour the asphalt sample to be tested into the anti-stick layer 32 until the sample liquid level is flush with the horizontal line engraved on the inner wall of the inner cylinder 31. Then, insert the positioning insert 4 into the positioning groove 122 while the left side of the positioning insert 4 is in close contact with part of the auxiliary block 33. The gravity ball 34 is inserted outside the auxiliary block 33. Because the positioning insert 4 is in contact with part of the auxiliary block 33, it abuts against the gravity ball 34, so the gravity ball 34 will not slide down. After installation, insert the mounting block 112 at the bottom of the dust cover 11 back into the auxiliary groove 121, and then insert the push rod 35 into the insertion hole 111. The push rod 35 is brought back until the lower part of the truncated cone contacts the six auxiliary blocks 33 without any other force. The stopwatch is pressed, and when 30 seconds have elapsed, the inspector quickly pushes the push-pull ring 36 downwards until it can no longer be pushed. The push-pull ring 36 moves the push rod 35 downwards. Because the diameter of the push rod 35 is larger than the diameter of the cylindrical cavity formed inside the six auxiliary blocks 33, the six auxiliary blocks 33 will push outwards and jam the gravity ball 34 as the push rod 35 moves downwards, preventing the push rod 35 from moving downwards. The depth of the gravity ball 34 is measured by observing the scale line on the push rod 35. The asphalt stuck to the inner cylinder 31 and gravity ball 34 is cleaned. Because the inner cylinder 31 has an anti-sticking layer 32, it is easier to clean. After cleaning, a different type of asphalt is used and the operation is repeated. The measured depths are compared to obtain a rough viscosity comparison.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended 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 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 utility model should be included within the protection scope of the present utility model.
