[0023] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0024] Please refer to Figure 1-Figure 7 The roadbed compaction detection equipment comprises: a gantry 1 and a ring cutter 5 arranged in the gantry 1, and a lifting ring is fixedly installed on the top of the gantry 1, an electric push rod 1 2 is fixedly installed on the inner wall of the top of the gantry 1, an external connecting frame 3 is fixedly installed on its output shaft, a round table 4 is fixedly installed on the bottom of the external connecting frame 3, and the bottom of the round table 4 is in contact with the top of the ring cutter 5, and electric push rods 2 6 are fixedly installed on the outer walls of both sides of the gantry 1, and electric push rods 3 7 are fixedly installed on the output shafts of the two electric push rods 2 6. In addition, movable openings are opened on both sides of the gantry 1, and the two electric push rods 3 7 are respectively arranged from the two sides. The two electric push rods 3 7 pass through a movable opening so that the electric push rod 3 7 can be lifted up and down, and a connecting piece 8 is fixedly installed on the output shafts of the two electric push rods 3 7, and a connecting rod 9 is fixedly installed on the side where the two connecting pieces 8 are close to each other, and an arc scraper 10 is fixedly installed on the end where the two connecting rods 9 are close to each other. The inner ring wall of the arc scraper 10 is triangular cone, and the two arc scrapers 10 are adapted to the ring knife 5. When the two arc scrapers 10 are engaged with each other, the ring knife 5 is just stuck between the two, and the inner ring wall of the triangular cone is in contact with the ring knife 5, so that the output shaft of the electric push rod 2 6 can be started to extend to scrape off the attachments on the ring knife 5.

[0025] In the above method, in order to facilitate the disassembly and assembly of the ring cutter 5, a socket 11 is opened on the truncated table 4, and a connecting block 12 is inserted therein. The bottom of the connecting block 12 is fixedly connected to the ring cutter 5, and embedding grooves 13 are opened on both sides of the connecting block 12. A positioning mechanism is provided in the external connecting frame 3, which is used to insert the embedding groove 13 to clamp the connecting block 12.

[0026] The positioning mechanism mentioned above includes an inner connecting frame 14, which is fixedly installed on the top of the truncated table 4. Embedded rods 15 are slidably installed on both sides of the inner connecting frame 14. The ends of the two embedded rods 15 close to each other extend into the two embedded grooves 13 respectively. A cross bar 16 is fixedly installed on the inner connecting frame 14. Two connecting plates 17 are slidably installed on the cross bar 16. The sides of the two connecting plates 17 close to each other are respectively fixedly connected to the two embedded rods 15. Side blocks 18 are fixedly installed at both ends of the cross bar 16. Two top springs 19 are sleeved on the cross bar 16. The ends of the two top springs 19 close to each other are respectively fixedly connected to the two connecting plates 17, and the ends of the two top springs 19 away from each other are respectively fixedly connected to the two side blocks 18. In addition, pull plates are fixedly installed on the tops of the two connecting plates 17, and finger rings are fixedly installed on the two pull plates to facilitate people to pull the connecting plates 17.

[0027] The working principle of the roadbed compaction detection equipment provided by the utility model is as follows:

[0028] When using the ring cutter 5 for sampling, first place the gantry 1 at the designated sampling position by means of the hand-carrying ring, then start the output shaft of the electric push rod 2 to extend, and the output shaft brings the round table 4 and the ring cutter 5 down, and when the cutting edge at the bottom of the ring cutter 5 contacts the roadbed surface, it starts to sink into the roadbed;

[0029] Until the truncated table 4 contacts the roadbed surface, the sampling is completed, and then the output shaft of the electric push rod 1 2 is started to retract, and the ring knife 5 automatically rises with the sample and finally moves out of the roadbed. Then, the output shafts of the two electric push rods 3 7 are started to extend, and the two arc scrapers 10 approach each other. Finally, the two arc scrapers 10 are engaged with each other, and the triangular cone inner ring wall of the arc scraper 10 contacts the outer wall of the ring knife 5. Then, the output shaft of the electric push rod 2 6 is started to extend, and the two arc scrapers 10 begin to descend, so that the soil and other debris attached to the ring knife 5 can be quickly scraped off until it is moved out from the bottom of the ring knife 5. Then, the above steps are reversed to bring the arc scraper 10 back to the original position.

[0030] After that, the two pull plates are pulled away from each other, and the two embedded rods 15 move away from each other until the embedded rods 15 are pulled out of the embedded grooves 13, and the top springs 19 are compressed at this time, and the connecting block 12 loses the effect of holding foreign objects, and then the ring knife 5 is removed for weighing detection;

[0031] After the detection is completed, the sample in the ring knife 5 is ejected, and the ring knife 5 is reinstalled on the round table 4.

[0032] Compared with the related art, the roadbed compaction detection equipment provided by the utility model has the following beneficial effects:

[0033] The utility model provides a roadbed compaction detection device, which can clamp the ring knife 5 between the two arc scrapers 10 that can be engaged with each other, and then use the extension of the output shaft of the electric push rod 26 to quickly scrape off the attachments on the outer wall of the ring knife 5 without leaving any dead angle, so as to ensure the accuracy of the subsequent weighing detection results, and through the plug-in connection between the embedded rod 15 and the embedded groove 13, the ring knife 5 can be quickly disassembled and assembled, which is convenient for people to operate and use.
