A cutting cylinder 8 is provided. The pressurizing assembly 9, main pipe 10, pneumatic rod 11, and clamping plate 12 are used to rotate the motor 4 and electric slide rail 2 when drilling and digging holes, so that the cutting cylinder 8 rotates and cuts the ground. Then, the air pump 91 and connecting cylinder 95 are connected together and the air pump 91 is started. The output shaft of the pneumatic rod 11 extends and drives the clamping plate 12 to move and press the soil into the inside of the cutting cylinder 8.

This design can avoid the soil being left inside the hole and difficult to clean when the cutting cylinder 8 rises.

[0023] Multiple grooves 13 are symmetrically provided on the front and rear sides of the trolley 1, extending downwards through the trolley 1. A positioning assembly 14 is installed above the grooves 13 and mounted on the top of the trolley 1. The positioning assembly 14 includes a positioning frame 141 fixedly connected to the top of the trolley 1 and symmetrically arranged. A positioning plate 142 is slidably connected to the inner side of the positioning frame 141.

After the collection is completed, the two operators' feet can be removed from the positioning pedal 145, and the limiting spring 144 resets, driving the positioning plate 142 and positioning pedal 145 to reset, so as to prevent the positioning pedal 145 from affecting the movement of the trolley 1.

[0024] Workflow: Before use, power on the equipment and connect the external control device. When drilling or digging holes, push the trolley 1 to the desired drilling position, screw the cutting cylinder 8 onto the bottom of the second connecting plate 7, and have the two operators place their feet on the positioning pedals 145 inside the groove 13, ensuring the bottom of the positioning pedals 145 is firmly against the ground. At this time, the positioning plate 142 slides inside the positioning frame 141, and the limiting spring 144 outside the limiting rod 143 is compressed to near its limit. The weight of the two operators is enough to firmly fix the trolley 1, preventing it from moving during operation. The next step is to start the rotating motor. 4 and electric slide rail 2, causing the slide plate 3 to slide downwards between the two electric slide rails 2, driving the rotary motor 4 to descend.

When the cutting cylinder 8 reaches its height limit, the rotary motor 4 and electric slide rail 2 are turned off. The first quick-release connector 93 at one end of the hose 92 is connected to the second quick-release connector 94 on one side of the connecting cylinder 95, and the air pump 91 is started. At this time, the air pump 91 draws outside air through the hose 92 and the first quick-release connector. 93. The second quick-release connector 94 and connecting cylinder 95 enter the inner side of the main pipe 10. The air pressure inside the main pipe 10 increases, causing the output shaft of the pneumatic rod 11 to extend. The clamping plate 12 moves with the output shaft of the pneumatic rod 11, pressing the soil tightly against the inner side of the cutting cylinder 8. Then, the electric slide rail 2 is activated, and the sliding plate 3 moves, driving the rotating motor 4 and its connecting components to rise. The soil pressed against the inner side of the cutting cylinder 8 detaches from the hole and rises with the cutting cylinder 8. At this time, a container can be placed under the cutting cylinder 8. The air pump 91 is adjusted to extract the air from the inside of the main pipe 10 and the pneumatic rod 11. The clamping plate 12 is reset, and the cutting cylinder 8 is removed from the second connecting plate 7. By unscrewing the bottom, the soil in the cutting cylinder 8 can be collected. Then, the compaction degree of the roadbed can be measured by the sand filling method. The setting of the pressurizing component 9 and its connecting components can make the soil in the hole stick tightly to the inner wall of the cutting cylinder 8, so as to avoid the soil being left inside the hole and difficult to clean when the cutting cylinder 8 rises. After the collection is completed, the feet of the two operators can be removed from the positioning pedal 145. The limit spring 144 resets and drives the positioning plate 142 and the positioning pedal 145 to reset, so as to avoid the positioning pedal 145 affecting the movement of the trolley 1. The design of the positioning component 14 can position the trolley 1 and prevent the hole from being damaged when the trolley 1 moves during the operation of the device.
