When detecting the compaction of the roadbed, first select a flat test point, then hammer the ring cutter 2 with a tool to make the ring cutter 2 completely enter the earthwork, then use the tool to dig out the ring cutter 2 in the earthwork, and then clean the edge of the ring cutter 2 with the tool, and finally test the weight and humidity of the earthwork in the ring cutter 2 through the laboratory to obtain In order to measure the compaction degree of the roadbed, in actual operation, the staff needs to manually hammer the ring cutter 2 so that the ring cutter 2 can completely enter the earth to take samples of the roadbed. However, it is difficult to completely chisel the cylinder of the ring cutter 2 into the earth by manually hammering the ring cutter 2, and the operation is labor-intensive. When it is convenient to completely chisel the cylinder of the ring cutter 2 into the earth, a striking rod 9 is installed to facilitate the complete chiseling of the cylinder of the ring cutter 2 into the earth. First, the ring cutter 2 is placed under the directional cover 3, and then the motor 6 is started to rotate by wireless remote control. At the same time, the eccentric wheel 7 drives the striking rod 9 to reciprocate in the storage box 4 through the connecting rod group 8. When the striking rod 9 reciprocates, the ring cutter 2 will be struck through the directional cover 3. The impact force generated by the striking will cause the ring cutter 2 to enter the earth to take samples of the roadbed and measure the compaction degree, replacing the operation of manual hammering sampling and reducing the labor intensity of the operator.

[0031] Working principle: when it is necessary to completely chisel the cylinder of the ring cutter 2 into the soil, the striking rod 9 is installed to facilitate the complete chiseling of the cylinder of the ring cutter 2 into the soil. First, the ring cutter 2 is placed under the directional cover 3, and then the motor 6 is started to rotate by wireless remote control. At the same time, the eccentric wheel 7 drives the striking rod 9 to reciprocate in the storage box 4 through the connecting rod group 8. When the striking rod 9 reciprocates, it will strike the ring cutter 2 through the directional cover 3. The impact force generated by the striking will cause the ring cutter 2 to enter the soil, sample the roadbed and measure the compaction degree, replace the operation of manual hammer sampling, and reduce the labor intensity of the operator. When it is necessary to clean the excess soil at the bottom of the ring cutter 2, the scraper 22 is installed to facilitate the cleaning of the excess soil at the bottom of the ring cutter 2. The method is as follows: first, the ring cutter 2 knocked into the ground is dug out by a tool, and then the dug ring cutter 2 is placed upside down on the supporting tube 17, and then the No. 2 electric push rod 23 is started to move the scraper 22 to the edge of the ring cutter 2, and then the motor 19 is started to rotate by wireless remote control. The motor 19 will drive the half gear 21 to rotate through the full gear 20. When the half gear 21 rotates, it will synchronously drive the scraper 22 to scrape and clean the soil at the edge of the ring cutter 2, so as to avoid errors caused by accidental shaking during manual cleaning, reduce errors, and improve detection efficiency and accuracy, so as to control the forward and reverse rotation of the motor 19, and drive the meshing half gear 21 through the synchronously rotating full gear 20 to drive the scraper 22 to rotate in an arc, so as to clean the excess soil at the bottom of the ring cutter 2.
