detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in Figure 1, Figure 2 and Figure 3, the utility model provides a technical solution: a sampling device for engineering geological exploration, including an outer column 1, and first handles are hinged on the left and right sides of the top of the outer column 1 2. The bottom end of the outer column 1 is provided with a sampling tube 3, and the sampling tube 3 is helical, which reduces sinking resistance and increases the number of soil samples retained in the sampling tube 3. The bottom end of the sampling tube 3 A drill bit 4 is integrally formed, and the outer surface of the drill bit 4 is provided with threads to increase the pressure when breaking the ground and save manpower. The inner cavity of the outer column 1 is provided with an inner column 5, and the upper part of the inner column 5 runs through the outer column 1 The left and right sides of the top of the inner column 5 are hinged with a second handle 6, which can be folded up and tightened when not in use, saving floor space and convenient for storage. The bottom end of the inner column 5 is provided with a baffle 7, so that The lower surface of the baffle plate 7 is provided with a push rod 8, and the push rod 8 is arranged in the sampling pipe 3, and a fastening device 9 is provided between the first handle 2 and the second handle 6 to prevent the inside from entering the soil layer. The column 7 is pushed upwards to collect useless soil. The fastening device 9 includes a lock 901 and a lock hook 902. The lock 901 is rotatably connected to the outer side wall of the second handle 6, and the lock 902 is fixedly connected. At the position corresponding to the outer wall of the first handle 2 and the lock 901 .

Specifically, the push rod 8 is helical, and the rotation angles of the sampling tube 3 and the push rod 8 are the same, so that the push rod 8 can move smoothly in the sampling tube 3 .

Specifically, the side walls where the first handle 2 is in contact with the outer column 1 and the side walls where the second handle 6 is in contact with the inner column 5 are pasted with a shock-absorbing layer 10 to prevent repeated opening and closing, causing damage to the handle or Damage to the contact part of the inner column 7 and the outer column 1.

Specifically, the side wall of the outer column 1 is provided with a height scale 11, so that the operator can clearly know the lowering position.
