[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1 and Figure 2 , the utility model provides an embodiment: a compaction degree measuring device for highway construction management, including a fixed plate 1, the left and right sides of the fixed plate 1 are fixedly connected with a connecting plate 3, the top wall of the left connecting plate 3 is fixedly connected with a servo motor 4, the output end of the servo motor 4 is fixedly connected with a threaded rod 5, the outer wall of the threaded rod 5 is threadedly connected with a displacement plate 6, the inner wall of the displacement plate 6 is fixedly installed with a collection bucket 7, the top wall of the right connecting plate 3 is fixedly connected with a sliding column 8, the top end of the sliding column 8 passes through the right side of the inner wall of the displacement plate 6, the inner wall of the collection bucket 7 is provided with a sealing plate 9, the bottom wall of the sealing plate 9 is fixedly connected with a connecting column 10, the bottom end of the connecting column 10 is fixedly connected with a threaded column 11, the bottom end of the threaded column 11 is threadedly connected with a cleaning disk 12, and the bottom wall of the collection bucket 7 is threadedly connected with a collection port 15; a plurality of collecting holes 13 are equidistantly provided on the top wall of the cleaning disk 12;

[0030] Specifically, after starting the servo motor 4, the motor will drive the threaded rod 5 to rotate. In this process, the sliding column 8 plays a key role. It limits the rotation of the displacement plate 6 so that it can only perform linear lifting and lowering motion in the vertical direction. This in turn drives the collection bucket 7 to move and then start the collection work. The collected sample enters the interior of the collection bucket 7, so that the collected sample pushes the cleaning disk 12 to move. The unique design of the cleaning disk 12 can effectively clean the inner wall of the collection bucket 7, thereby reducing the retention of residual substances. This design not only improves the efficiency of the sampling work, but also ensures the accuracy of the sampling results. The design of the cleaning disk 12 also takes into account the convenience of cleaning and maintenance. By rotating the cleaning disk 12, it can be separated from the threaded column 11, so that the cleaning work can be conveniently carried out, and the multiple collection holes 13 make it possible to collect the cleaned residues.

[0031] Reference Figure 1 and Figure 3A fixing mechanism 2 is provided at the rear side of the fixing plate 1, and the fixing mechanism 2 includes an L-shaped plate 201, the bottom of the L-shaped plate 201 is fixedly connected to the rear side of the fixing plate 1, the inner top wall of the L-shaped plate 201 is fixedly connected to a hydraulic rod 202, the output end of the hydraulic rod 202 is fixedly connected to a movable plate 203, the front and rear sides of the top wall of the movable plate 203 are fixedly connected to mounting plates 204, the top walls of the two mounting plates 204 are threaded with threaded knobs 205, and the bottom ends of the two threaded knobs 205 are threadedly connected to cones 206;

[0032] Specifically, by starting the hydraulic rod 202, the movable plate 203 is displaced. As the movable plate 203 moves, the two cones 206 are also displaced accordingly, so as to fit tightly to the road surface. This fitting method not only improves the fixing effect on the road surface, but also effectively reduces the interference caused by the shaking of the device, further ensuring the accuracy and reliability of the collected detection results. By turning the two threaded knobs 205, the replacement and disassembly of the cone 206 is realized. In actual applications, the cone 206 may be worn due to long-term use or the influence of road conditions. At this time, the cone 206 can be easily replaced by simply turning the threaded knob 205.

[0033] Reference Figure 1 , Figure 2 and Figure 3 A control switch 18 is fixedly connected to the front side of the fixed plate 1, and the control switch 18 is electrically connected to the hydraulic rod 202 and the servo motor 4 respectively; a protective shell 19 is provided on the front side of the control switch 18, and the rear side of the protective shell 19 is rotatably connected to the front side of the fixed plate 1 through a hinge;

[0034] Specifically, the control switch 18 can open and close the device through the control switch 18 electrically connected to the hydraulic rod 202 and the servo motor 4 respectively, and the protection shell 19 can protect the control switch 18 and prevent accidental touch.

[0035] Reference Figure 1 The top wall of the sealing plate 9 is fixedly connected with a handle 14, and the top wall of the sliding column 8 is fixedly connected with a limiting rod 16; the inner wall of the fixed plate 1 is fixedly installed with a cleaning sponge 17; the four corners of the bottom wall of the fixed plate 1 are fixedly installed with universal wheels 20;

[0036] Specifically, the handle 14 makes it easy to lift the cleaning plate 12, the limiting rod 16 can limit the displacement of the displacement plate 6, the cleaning sponge 17 makes it possible to clean the outer wall of the collection port 15 and the collection bucket 7, and the multiple universal wheels 20 make it easy to move the device.

[0037] Working principle: When starting to collect, the threaded rod 5 is driven by starting the servo motor 4, and then when the sliding column 8 limits the rotation of the displacement plate 6, the displacement plate 6 completes the purpose of linear lifting, thereby driving the collection bucket 7 to displace, so that the collection work is carried out through the collection port 15, and the collected sample enters the interior of the collection bucket 7, so that the cleaning disk 12 can be pushed to displace, and then the inner wall of the collection bucket 7 is cleaned, thereby reducing the retention of residual substances and ensuring the accuracy of the sampling results. By rotating the cleaning disk 12, the cleaning disk 12 can be separated from the threaded column 11 for cleaning, thereby increasing the service life of the cleaning disk 12, and by starting the hydraulic rod 202, the movable plate 203 is displaced, thereby driving the two cones 206 to displace, thereby improving the fixing effect on the road surface and reducing the situation where shaking interferes with the collection and detection results. By rotating the two threaded knobs 205, the cone 206 can be replaced and disassembled, thereby reducing the use cost of the device and improving flexibility.
