[0029] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] Reference Figure 1-Figure 7 As shown, this embodiment provides a blown fill muddy soil sampler, including a frame, a driving assembly is arranged on the frame, the output end of the driving assembly is drivingly connected to a sampling tube 1, a sampling drill bit 2 is arranged at the bottom end of the sampling tube 1, and the sampling drill bit 2 is arranged correspondingly and connected to a storage chamber 3 in the sampling tube 1;

[0031] The sampling drill bit 2 includes a fixed disk 4 detachably connected to the bottom end of the sampling tube 1, a movable head 5 is provided at the bottom end of the fixed disk 4 for limited rotation, a cutting cavity 6 in the movable head 5 is correspondingly arranged and connected to the storage cavity 3; a cutting assembly is arranged between the fixed disk 4 and the movable head 5;

[0032] The cutting assembly includes a plurality of cutting blades 7 slidably connected to the top of the movable head 5 , and the cutting blades 7 extend into the cutting cavity 6 .

[0033] The utility model discloses a blown-filled muddy soil sampler. When in use, a sampling tube 1 is mounted on a driving assembly on a frame, and then a sampling drill bit 2 is mounted on the bottom end of the sampling tube 1. The drill bit drills into the blown-filled muddy soil mountain, so that the blown-filled muddy soil enters the storage cavity 3 of the sampling tube 1 and is cut and separated from the surrounding areas; a fixed disk 4 and a movable head 5 of the sampling drill bit 2 are limitedly rotated, and a cutting cavity 6 of the movable head 5 cuts the blown-filled muddy soil. When drilling, the sampling tube 1 drives the sampling drill bit 2 to drill, and the blown-filled muddy soil sample enters the storage cavity 3 from the cutting cavity 6. At this time, the cutting assembly is retracted into the movable head 5. After the sampling is completed, the driving assembly is reversed, and a misalignment occurs between the fixed disk 4 and the movable head 5. The cutting assembly is driven to make the cutting blade 7 extend into the cutting cavity 6 and rotate in the opposite direction under the drive of the driving assembly, thereby disconnecting the blown-filled muddy soil sample from the original area. At the same time, a plurality of cutting blades 7 can also serve as a supporting structure in the blown-filled muddy soil sample to prevent the taken-out blown-filled muddy soil sample from falling. The utility model has a simple structure and is easy to use, and can accurately realize the sampling of blown-fill muddy soil. At the same time, it can conveniently cut off the connection between the blown-fill muddy soil sample and the ground structure, and reduce the blown-fill muddy soil samples taken out, thereby improving the sampling efficiency and improving the sample quality.

[0034] A further optimized solution is that a plurality of receiving grooves 8 connected to the cutting chamber 6 are provided at the top of the movable head 5, and the cutting blade 7 is slidably arranged in the receiving groove 8; a power rod 9 is fixedly connected to the side of the cutting blade 7 away from the cutting chamber 6, and the power rod 9 extends out of the receiving groove 8 and is transmission-connected to the fixed disk 4; a plurality of arc-shaped driving grooves 10 are provided at the bottom end of the fixed disk 4, and the driving groove 10 is arranged corresponding to the power rod 9, and the power rod 9 extends into the driving groove 10 and is in sliding contact with the driving groove 10. The driving groove 10 is arranged in an arc shape, and the distance between the driving groove 10 and the center of the cutting chamber 6 is arranged to be unidirectionally gradually changed. When the sampling drill bit 2 drills in to take samples, the fixed disk 4 rotates driven by the sampling tube 1, and the positions of the driving groove 10 and the power rod 9 change, and finally the power rod 9 is located at the end of the driving groove 10 away from the cutting cavity 6, driving the cutting blade 7 to be retracted into the accommodating groove 8 without affecting the sampling process. At the same time, the far end of the driving groove 10 drives the movable head 5 to rotate through the power rod 9, so that the sample cut by the cutting blade 7 enters the storage cavity 3 during the drilling process; and when the sampling is completed and the sampling drill bit 2 needs to be taken out, the fixed disk 4 is rotated in the opposite direction, and the positional relationship between the power rod 9 and the driving groove 10 changes, and finally moves to the end of the driving groove 10 close to the cutting cavity 6. At this time, the power rod 9 pushes the cutting blade 7 into the cutting cavity 6, and after reaching the end of the driving groove 10, it drives the interactive head to reverse, and then separates the bottom end of the last sample through the cutting blade 7.

[0035] Furthermore, the included angle between the driving groove 10 and the center of the cutting chamber 6 in this embodiment is 90°, so that the free angle between the fixed disk 4 and the movable head 5 is 90°.
