[0021] A kind of excavation equipment for compaction detection includes a shell 1, and a pedal plate 2 is fixedly connected to the outside of the shell 1; the pedal plate 2 can facilitate the user to step on the equipment during work, and at the same time prevent the equipment from being lifted up when the electric cylinder 3 drives the pressure cylinder 4 to press down. An excavation assembly is installed in the shell 1, and the excavation assembly includes an electric cylinder 3 fixedly connected to the inner wall of the top of the shell 1, and the output end of the electric cylinder 3 is fixedly connected to the pressure cylinder 4, and the pressure cylinder 4 is used to limit the excavation range. The pressure cylinder 4 is slidably connected between the inner sides of the shell 1, and there are soil pieces 5 distributed in a circle around the pressure cylinder 4. The soil pieces 5 are made of alloy material and are arranged in a sheet shape to effectively increase the pressure when they are descended, so as to facilitate soil crushing. A fixed elbow 6 is also arranged in the pressure cylinder 4, and one end of the fixed elbow 6 is connected to a hose 7, and one end of the hose 7 is connected to the pump body outside the shell 1. The fixed elbow 6 is used to cooperate with the hose 7 to extract the crushed soil through the pump body, reducing the user's subsequent workload. The hose 7 is convenient for cooperating with the pressure cylinder 4 to reduce and change its own length. The pump body can use a sludge vacuum pump with model GNSP-10B to extract the crushed soil in the pressure cylinder 4 under negative pressure.

[0022] Furthermore, a port 8 is fixedly connected to the outer wall of the shell 1, and the hose 7 and the input end of the pump body are connected to the two ends of the port 8 by a pipe respectively. A discharge port 9 is fixedly connected to one side of the top of the pressure cylinder 4, and the hose 7 and one end of the fixed elbow 6 are respectively connected to the discharge port 9. The port 8 and the discharge port 9 are respectively used for connection between pipelines, which facilitates the discharge of crushed soil and reduces the subsequent manual workload.

[0023] Furthermore, a guide portion 10 is provided on the outer upper side of the pressing cylinder 4, and a sharp edge 11 is fixedly connected to the bottom of the pressing cylinder 4. The guide portion 10 is convenient for guiding the lifting and lowering movement of the pressing cylinder 4, and the sharp edge 11 is used to reduce the contact area to increase the pressure when the pressing cylinder 4 contacts the ground, which is conducive to determining the scope of the pit and can quickly break the ground.

[0024] Furthermore, the soil crushing piece 5 is in a D-shaped structure, and a notch 12 is provided on the soil crushing piece 5. The notch 12 can facilitate the crushed soil to enter the lower entrance of the fixed elbow 6, so as to facilitate the discharge of the soil.

[0025] Furthermore, the soil crushing pieces 5 are also provided with a convex portion 13 protruding toward the central axis of the pressing cylinder 4. The straight pipe section of the fixed elbow 6 is located between adjacent sides of multiple soil crushing pieces 5. The convex portion 13 can facilitate the crushing of soil near the inlet of the fixed elbow 6 to avoid blocking the inlet of the fixed elbow 6, thereby improving the reliability of the equipment.

[0026] Furthermore, a fixing ring 14 is fixedly connected around the bottom of the pedal plate 2, and handles 15 are fixedly connected to the left and right sides of the top of the pedal plate 2. The fixing ring 14 is used to locate the position of the device on the ground, and the handles 15 can be easily lifted to move the device.

[0027] Working principle is the process:

[0028] 1) When in use, first determine the location of the test pit, place the device above the determined location, and the user steps symmetrically on the pedal plate 2 with both feet, so that the fixing ring 14 is pressed into the ground soil under pressure to position the device.

[0029] 2) Then connect the device to an external power source, and control the electric cylinder 3 and the pump body to work through the controller. The electric cylinder 3 drives the pressing cylinder 4 to move and descend in the housing 1, and at the same time, it is guided by the guide part 10 to slide. When the broken soil pieces 5 and the sharp edge 11 contact and squeeze the soil, the soil in the test pit is cut into pieces. The broken soil enters the fixed elbow 6 from the notch 12 or the gap through the negative pressure, and is finally drawn out of the outer side of the housing 1 through the hose 7, completing the excavation work.
