Technical Field
[0001] The utility model relates to the field of drilling devices, in particular to a drilling device for detecting asphalt content of asphalt pavement samples. Background Art
[0002] Asphalt pavement refers to various types of pavement paved with road asphalt materials mixed into mineral materials. The asphalt binder improves the ability of paving aggregate to resist damage to the road surface caused by driving and natural factors, making the road surface smooth, dust-free, waterproof and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction. The asphalt structural layer of asphalt pavement itself belongs to the category of flexible pavement, but in addition to flexible materials, its base layer can also use rigid cement concrete or semi-rigid hydraulic materials.
[0003] After the asphalt pavement is laid, its asphalt content needs to be tested. The quality of asphalt will directly affect the construction effect, performance and service life of the pavement. In order to ensure the construction quality, the asphalt content of the pavement will be tested.
[0004] In the existing asphalt sampling process, a drill sampling device is usually used. By drilling holes in the asphalt pavement, the asphalt drilled by the drill bit is discharged to a unified position through the drilling device. Since asphalt has a certain viscosity, it is easy to cause the discharge position to stick during the discharge process. When the asphalt sticks at the discharge position, it is easy to cause discharge difficulties. This will cause the material sampling and detection to be untimely, which will ultimately affect the detection data. Utility Model Content

[0009] By adopting the above technical solution and setting the residual gear, the first gear can be operated intermittently, thereby providing sufficient time for the first spring to reset, making the overall operation smoother and ensuring stable operation of the equipment.
[0010] The utility model is further configured such that a second gear is fixedly mounted on the other end of the movable rod, and a toothed plate is provided on one side of the second gear, the toothed plate and the second gear are meshingly connected, a connecting rod is movably mounted inside the sleeve, a rotating shaft is installed in the middle of the connecting rod, and a rubber block is fixedly mounted on one end of the connecting rod.

[0013] By adopting the above technical solution and setting the inclined surface of the collecting box, the collecting box can be unloaded more smoothly, thus preventing the asphalt from staying at the junction of the collecting box and the sleeve.
[0014] The utility model is further configured that a second spring is installed on one side of the connecting rod, and the connecting rod and the sleeve are connected through the second spring, a first spring is sleeved on the outer side of the steel cable, and the slider and the sleeve are slidably connected.
[0015] By adopting the above technical solution and setting a slider, the scraper can be limited by the slider during movement, ensuring that the scraper will not deviate, making the overall cleaning effect more stable.
[0016] In summary, the utility model mainly has the following beneficial effects:
[0017] The utility model provides a scraper and a movable rod. When the rotating rod rotates during the material taking process, it can drive the movable rod to rotate, so that the scraper moves.

At the same time, it can save material taking time and is more conducive to timely detection of asphalt samples. By providing a rubber block and a toothed plate, when the movable rod rotates, the connecting rod can be squeezed by the movement of the toothed plate, so that the rubber block rotates under the action of the rotating shaft, constantly collides with the collecting box, thereby reducing the gap between the asphalt positions inside the collecting box, and being able to hold more samples, which is more conducive to the detection of big data.

When the first gear 11 rotates, the first gear 11 can pull the steel cable 15, so that the slider 14 is displaced, thereby displacing the scraper 3. At the same time, the first spring 16 is squeezed. When the teeth of the residual gear 12 no longer contact the first gear 11, the first gear 11 is reset under the action of the first spring 16, realizing the reciprocating movement of the scraper 3, so that the position of the discharge port 2 can be scraped, so that the asphalt no longer sticks, thereby increasing the feeding speed.
[0027] See also Figure 2-3 A movable shaft 13 is movably installed on one side of the sleeve 1, and a broken gear 12 is fixedly installed on one end of the movable shaft 13. A chain is sleeved on one side of the broken gear 12, and the broken gear 12 is connected to the rotating rod 8 by the chain. A first gear 11 is fixed on one end of the movable rod 10, and the first gear 11 and the broken gear 12 are meshingly connected. Through the setting of the broken gear 12, the first gear 11 can be intermittently operated, thereby providing enough time for the first spring 16 to reset, making the overall work smoother and ensuring the stable operation of the equipment.
[0028] See also Figure 3 , 5 A second gear 17 is fixedly installed at the other end of the movable rod 10, and a tooth plate 18 is provided on one side of the second gear 17. The tooth plate 18 and the second gear 17 are meshingly connected. A connecting rod 5 is movably installed inside the sleeve 1, and a rotating shaft 20 is installed in the middle of the connecting rod 5. A rubber block 6 is fixedly installed at one end of the connecting rod 5. Through the setting of the rubber block 6, when the rubber block 6 collides with the collection box 4, the asphalt inside the rubber block 6 can be compressed, and the material of the rubber block 6 will not generate a large noise during the collision, and the collision compression effect is more efficient.
[0029] See also Figure 1 A collecting box 4 is installed on one side of the sleeve 1, and one side of the collecting box 4 is set as an arc surface. The collecting box 4 fits with the rubber block 6. The inclined surface of the collecting box 4 makes the material discharge of the collecting box 4 smoother, avoiding the asphalt staying at the junction of the collecting box 4 and the sleeve 1.
[0030] See also Figure 5 A second spring 19 is installed on one side of the connecting rod 5, and the connecting rod 5 is connected to the sleeve 1 through the second spring 19.

By setting the slider 14, the scraper 3 can be limited by the slider 14 during the movement, ensuring that the movement of the scraper 3 will not be offset, making the overall cleaning effect more stable.
[0031] The working principle of the utility model is as follows: when it is necessary to sample asphalt, the motor 21 is started, so that the rotating rod 8 rotates, and when the rotating rod 8 rotates, the spiral blade 9 is driven to rotate, and the drilling work is started at this time, and the asphalt moves along the spiral blade 9 to the discharge port 2. When the rotating rod 8 rotates, the bronze drum chain drives the movable shaft 13 to rotate, so that the residual gear 12 rotates. When the residual gear 12 rotates, the first gear 11 meshing with the residual gear 12 rotates intermittently. When the first gear 11 rotates, the first gear 11 can pull the steel cable 15, so that the slider 14 is displaced, thereby causing the scraper 3 to be displaced. At the same time, the first spring 16 is squeezed, and when the teeth of the residual gear 12 no longer contact the first gear 11, the first gear 11 is in the first It is reset under the action of the spring 16 to realize the reciprocating movement of the scraper 3, so that the position of the discharge port 2 can be scraped, so that the asphalt no longer sticks and the unloading speed is improved. When the movable rod 10 rotates, it drives the second gear 17 to rotate. At this time, the tooth plate 18 moves under the action of the second gear 17, so that the tooth plate 18 contacts one side of the connecting rod 5. Under the action of the rotating shaft 20, the connecting rod 5 rotates, so that the rubber block 6 rotates in the opposite direction. When the movable rod 10 is reset, the second gear 17 drives the tooth plate 18 to reset. At this time, the connecting rod 5 loses the extrusion force and resets under the action of the second spring 19, so that the rubber block 6 collides with the collecting box 4, causing the asphalt inside the collecting box 4 to shrink, thereby achieving the purpose of compressing the space.
