A sawtooth 4 is arranged at one end of the soil excavation sleeve 2, and the other end of the soil excavation sleeve 2 is connected to a pedal rod 3. The middle part of the pedal rod 3 is connected to a handle rod 1. A pulling cutter is installed on the soil excavation sleeve 2, and the pulling cutter includes an annular steel wire rope 6 and a transmission steel wire rope 8. A fixing groove 5 is provided on the inner wall side of the soil excavation sleeve 2 close to the sawtooth 4. The fixing groove 5 is an annular groove. An annular steel wire rope 6 is arranged inside the fixing groove 5. One side of the annular steel wire rope 6 is connected to the transmission steel wire rope 8, and one end of the transmission steel wire rope 8 is connected to a pull ring 7.

[0027] The utility model adds a pulling cutter and a guide and convergence device 17. The pulling cutter and the guide and convergence device 17 are combined. On the one hand, after the soil sampling sleeve 2 is inserted into the soil, the interior of the soil sampling sleeve 2 is filled with sampled soil. The personnel can manually pull the pull ring 7 to drive the annular steel wire rope 6 to cut the lower part of the sampled soil in the soil sampling sleeve 2, thereby eliminating the need to tighten the bolt to drive the cutter, which is convenient and quick. On the other hand, the guide and convergence device 17 can centrally store the cut annular steel wire rope 6, thereby preventing the disordered arrangement of the annular steel wire rope 6 from damaging the cut soil sample.

[0028] Material selection and feasibility analysis for specific implementation: The samples we actually made use the drawings in the specification as drawings, and are implemented according to the proportions and matching methods of the various components in the drawings in the specification. The connection is a common connection method such as strong adhesive connection, welding, riveting, flange connection, and one-piece molding connection. In actual production, the corresponding connection method, thickness and strength of the connection point can be selected according to the actual connection strength needs without creativity. The utility model is limited to land that can be smoothly cut by manually pulling the transmission wire rope 8 to drive the ring wire rope 6. After actual testing, the compacted land for paving the highway was sampled by the soil sampling sleeve 2, and it can be driven by personnel to manually pull the transmission wire rope 8 to drive the ring wire rope 6 to be smoothly cut. When encountering soil that is difficult to cut, personnel can add a manual hoist, the fixed end of the manual hoist is connected to the handle bar 1, and the pulling end of the manual hoist is connected to the pull ring 7, so as to use the manual hoist to increase the pulling force on the transmission wire rope 8. The transmission wire rope 8 and the ring wire rope 6 can use Kevlar reinforced wire ropes. The transmission steel wire rope 8 and the ring steel wire rope 6 can be selected with sufficient diameter according to actual needs, so as to ensure that the soil sampled by the soil sampling sleeve 2 can be smoothly cut. When sampling soil, the personnel can manually hold the handle bar 1, and then step on the pedal bar 3, so as to drive the soil sampling sleeve 2 to be inserted into the soil for sampling. After the soil sampling sleeve 2 is inserted into the soil, the personnel can manually pull the transmission steel wire rope 8, so as to drive the ring steel wire rope 6 to cut the lower part of the soil in the soil sampling sleeve 2, so as to separate the soil in the soil sampling sleeve 2 from the original soil, so as to facilitate the personnel to take out the sampled soil more smoothly when pulling out the soil sampling sleeve 2, and avoid the sampled soil from being adhered to the original soil and damaging the sampled soil.
