Specific embodiment
As shown in Figure 1, the utility model wet soil sampler, including cylinder and cutting ring 5, the lower end of the cylinder and institute
The knife spine for stating cutting ring 5 is fixedly connected, and the blade of the cutting ring 5 is axial downward along the cylinder；The cylinder include outer cylinder 3, in
Cylinder 2 and inner cylinder 1, the outer cylinder 3 and the middle cylinder 2 are heat insulation cylinder, and the inner cylinder 1 is heat-conducting cylinder, the lower end of the outer cylinder 3, institute
The lower end of the lower end and the inner cylinder 1 of stating middle cylinder 2 is fixedly connected with the knife spine of the cutting ring 5 respectively, middle 2 inner wall of cylinder and institute
It states and is equipped with gap 4 between the outer wall of inner cylinder 1, be lower than the liquid or gaseous coolant of zero degree in the gap 4 equipped with temperature.This implementation
In example, the outer cylinder 3 with a thickness of 0.5cm, the middle cylinder 2 with a thickness of 0.5cm, the width in the gap 4 is 0.8cm, institute
State inner cylinder 1 with a thickness of 0.3cm, 1 diameter of inner cylinder is 5cm.
In order to reduce the usage amount of gaseous coolant, the utilization efficiency of gaseous coolant is improved, in the present embodiment, in the cylinder
Upper end is equipped with lid 7, and 7 lower face of lid is equipped with gas chamber 8, and the upper face of the lid 7 is equipped with air inlet pipe 9, described
The outlet side of air inlet pipe 9 is connect with the inlet end fluid communication of the gas chamber 8, the outlet side of the gas chamber 8 and the gap 4
The connection of inlet end fluid communication；The lid 7 is connect with the outer wall thread of the outer cylinder 3, the lower face of the lid 7 with it is described
Cooperation is sealed at the top of 3 top of outer cylinder, middle 2 top of cylinder and the inner cylinder 1, when the lid 7 and 3 outer wall thread of outer cylinder
When connection, the lid 7 above 1 mesoporous of inner cylinder is equipped with through the logical of 7 upper face of lid and lower face
Hole is convenient for air and Free water when sampling inside the inner cylinder 1 to be discharged in this way.While in order to improve the lower plate of the lid 7
Leakproofness between 3 top of face and the outer cylinder, 1 top of middle 2 top of cylinder and the inner cylinder, in 7 lower face of lid
