Detailed Description
As shown in the attached drawings, the sampler for the soil comprises a sampling handle part 1, a sampling cylinder part 2, a sampling tip part 3, a sample outlet push rod 4, a push rod disc part 5 and a push rod piston head 6;
the sampling handle part 1 is of a rectangular plate-shaped structure, a round hole 7 is formed in the center of the sampling handle part 1, the sampling cylinder part 2 is fixedly arranged on the sampling handle part 1 below the round hole 7, the sampling cylinder part 2 and the round hole 7 are coaxially arranged, and the inner diameter of the sampling cylinder part 2 is larger than the aperture of the round hole 7;
the sample outlet push rod 4 penetrates through the circular hole 7 and extends into the sampling cylinder part 2, the top end of the sample outlet push rod 4 is connected with the push rod disc part 5, the end part, located in the sampling cylinder part 2, of the sample outlet push rod 4 is connected with the push rod piston head 6, the push rod piston head 6 comprises a cylindrical part 11 and an inverted circular truncated cone part 12 which are integrally formed, a screw 13 is fixedly arranged at the center of the upper part of the cylindrical part 11, a threaded hole 14 matched with the screw 13 is formed in the end part of the sample outlet push rod 4, and the side wall of the cylindrical part 11 is abutted to the inner wall of the sampling cylinder part 2;
sampling cylindric portion 2's lower extreme is equipped with internal thread portion 8, sampling point head 3 is cylindric structure and sets up with sampling cylindric portion 2 is coaxial, sampling point head 3's upper end be equipped with stretch into sampling cylindric portion 2 lower extreme and with internal thread portion 8 matched with external screw thread cover 9, sampling point head 3's lower extreme is inwards contracted and is formed sharp knife-edge portion 10.
The surface of the push rod disc part 5 is wrapped with a flexible rubber sleeve.
The length of the sampling tip part 3 is one third of the length of the sampling cylinder part 2.
The sampling handle part 1, the sampling cylinder part 2, the sampling tip part 3, the sample outlet push rod 4, the push rod disc part 5 and the push rod piston head 6 are all made of stainless steel.
The total length of the sampling cylinder part 2 and the sampling sharp head part 3 after being connected is the same as that of the sampling push rod 4.
The working principle is as follows: an operator firstly penetrates the sample outlet push rod 4 through the circular hole 7, extends into the sampling cylinder part 2 and pushes out the sample outlet push rod to the sampling cylinder part 2, then installs the push rod piston head 6, and then connects the sampling sharp head part 3 with the sampling cylinder part 2. In waiting to detect soil region, insert sampling point head portion 3 in soil, then hard the downward propelling movement sampling handle portion 1 can be sampled soil, and through propelling movement push rod disc portion 5 after the sampling is accomplished, can extrude the soil of gathering, then carry out follow-up analysis and detection. The sampler is convenient to mount and dismount, small in occupied size and convenient to carry and transport after being dismounted.
