[0028] The four corners of the bottom of the slat are fixedly connected with springs 15. By setting the springs 15, an auxiliary buffering effect is played, so that the mechanism can be used normally under different ground conditions and the wear of the mechanism can be reduced; the bottom of the spring 15 is fixedly connected with a frame plate 16, and the opposite side of the frame plate 16 is movably connected with a flattening roller 17 through a bearing. The four corners of the top of the frame plate 16 are fixedly connected with guide rods, and the top of the guide rods is slidably connected to the slat.

[0029] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 5 The right side of the bottom of the mounting frame 18 is connected to the base plate 1 by bolts, and the top of the left front side of the mounting frame 18 is fixedly connected to the push rod frame 19. The top of the push rod frame 19 is fixedly connected to the electric push rod 20, and the output end of the electric push rod 20 is fixedly connected to the sampling assembly 21;

[0030] A partition plate is fixedly connected to the left side of the top of the mounting frame 18, and an adjusting push rod 22 is fixedly connected to the rear side of the partition plate. The output end of the adjusting push rod 22 passes through the partition plate and is fixedly connected to a sample receiving box. By setting up the sample receiving box, it plays a role in assisting in receiving samples, which can reduce the workload of the staff, and the sample receiving is relatively smooth without spilling the sample soil.

[0031] See also Figure 1 、 Figure 2 and Figure 3 The surface of the wheel frame assembly 10 is provided with a track wheel 11, the right side of the top of the base plate 1 is connected to the drive assembly 12 by bolts, and the bottom of the left side of the angle plate 5 is fixedly connected with a reinforcing rib.

By providing the auxiliary support wheels, an auxiliary support effect is played, thereby preventing the left side of the entire device from being suspended in the air, thereby improving the stability of the device.

[0034] During use, due to the large area of ​​the mine, multiple devices can be used for landfilling at the same time. Before landfilling, it is necessary to go to the bottom of the mine along the coal transportation road at the edge of the pit to extract soil samples. By starting the electric push rod 20 on the push rod frame 19, the electric push rod 20 extends and pushes the sampling assembly 21 to penetrate the soil at the bottom of the pit to take samples. After completion, the electric push rod 20 drives the sampling assembly 21 to rise; then the adjustment push rod 22 is started to push the sample box to receive the sample soil taken out. This mechanism can effectively perform auxiliary sampling, thereby being able to evaluate the soil quality in preparation for subsequent reclamation, and being able to understand the specific conditions of the soil at the bottom of the mine in detail in order to formulate a landfill plan, thereby completing the auxiliary sampling process;

[0035] After taking it out, the driving device uses the landfill shovel mouth 8 to flatten the uneven places at the bottom of the mine, which is convenient for the subsequent construction of the landfill foundation. When it is ready, the device can be used for landfill. During landfill, the driving device is used to push the original soil at the edge of the mine into the pit in sequence through the cooperation of the first hydraulic rod 6, the shovel mouth frame 7 and the landfill shovel mouth 8. After each part is pushed down, it needs to be compacted and leveled;

[0036] Start the second hydraulic rod 14 to push the flattening roller 17 downward to contact the soil through the slats and frame plates 16. When the flattening roller 17 presses the soil during the movement, the spring 15 and the guide rod will cooperate with the buffer flattening roller 17. This mechanism can effectively level and compact the soil, thereby preventing the gaps in the landfilled soil from being too large, avoiding soil collapse and subsidence during subsequent recultivation, eliminating safety hazards, and preventing the bottom foundation from deformation, thereby completing the leveling and compaction process.
