DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 As shown, a soil sampling device for water conservancy construction includes a drill tube 2 and a positioning frame 1. The positioning frame 1 is fixed to the ground by a pin 105. The positioning frame 1 is sleeved on the outside of the drill tube 2 to guide the drill tube 2 up and down. A spiral blade 202 is provided on the outer wall of the drill tube 2, which can make it easier for the drill tube 2 to drill into the soil and transport the soil cut during drilling to the ground. A handle is connected to the upper end of the drill tube 2, and a lifting rod 3 is connected to the rotating cylinder. Figure 2 As shown, the lower end of the lifting rod 3 is provided with a plug 303 that matches the inner wall of the drill tube 2. Before the sampling depth is reached, the plug 303 blocks the lower end of the drill tube 2. When the sampling depth is reached, the plug 303 is lifted by the lifting rod 3, the lower end of the drill tube 2 is opened, and the drilling continues. The soil outside the drill tube 2 continues to be transported upward with the spiral blades 202, and the corresponding soil below the inner side of the drill tube 2 will enter the drill tube 2 for collection. Since the soil has a certain depth and viscosity, and under the action of the squeezing force, the soil in the drill tube 2 will not fall when the device is lifted upward, so as to achieve soil sampling at a specific depth.

[0025] The positioning frame 1 includes a guide sleeve 102 which is sleeved on the outside of the drill tube 2. A crossbeam 101 is connected to the outer wall of the guide sleeve 102. The end of the crossbeam 101 is connected to a support leg 103. A bottom plate 104 is provided at the lower end of the support leg 103. The bottom plate 104 is fixed by a pin 105. The guide sleeve 102 can keep the drill tube 2 vertical, thereby improving the stability during sampling.

[0026] In order to determine the depth, scale lines 201 indicating the depth are provided on the outer wall of the drill tube 2 , and the 0 scale line 201 is located at the lowest end of the drill tube 2 . The depth of the drill tube 2 drilling into the soil is determined by the scale lines 201 .

[0027] like Figure 4As shown, the upper end of the drill tube 2 is provided with a nut sleeve 203, the lifting rod 3 is threadedly matched with the nut seat, the upper end of the lifting rod 3 is connected with a handle 301, and the outer side of the lifting rod 3 is sleeved with a limit block 302. When the limit block 302 contacts the nut seat, the plug 303 just extends completely out of the drill tube 2. The plug 303 is a conical structure, which can not only seal the drill tube 2, but also reduce the resistance of the drill tube 2 drilling into the soil. In addition, the limit block 302 can speed up the reliability of the position of the plug 303 after it is extended.

[0028] The upper end of the drill tube 2 is sleeved with a handle seat 4, the handle is connected to the handle seat 4, the outer side of the handle is sleeved with a handle sleeve 6, and the end of the handle sleeve 6 is provided with a limiting ring 601 to ensure the stability of the grip.

[0029] like Figure 3 As shown, when in use, first, fix the positioning frame 1 by the pin 105; rotate the lifting rod 3 to make the plug 303 extend from the bottom of the drill tube 2, insert the drill tube 2 into the guide sleeve 102, and rotate the drill tube 2 by the handle to drill into the soil. When it reaches the specified depth, rotate the lifting rod 3 to raise the plug 303 to open the bottom of the drill tube 2, continue to rotate the drill tube 2 downward for sampling, and the soil enters the drill tube 2. After the sampling is completed, in order to ensure that the soil in the drill tube 2 will not fall out, you can first open the pin 105, loosen the positioning frame 1, shake the drill tube 2, so that the soil in the drill tube 2 and the underground soil are broken, and the drill tube 2 is taken out upward. The soil in the drill tube 2 is the sampling soil, and the lifting rod 3 is rotated to push out the soil sample in the drill tube 2 through the plug 303, which is convenient to use.

[0030] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
