Description

Technical Field

[0001] The utility model relates to the technical field of geological exploration, in particular to a sampling device. Background Art

[0002] In geological exploration, it is often necessary to use a soil sampler to sample geological soil. A soil sampler refers to a tool used to obtain soil samples. Commonly used ones include soil drills, shovels and spades. The soil drill consists of a drill bit and a handle made of hard material (steel or hard plastic). The drill bit is often spiral or cylindrical. The top of the spiral drill bit is a pair of sharp blades that can be rotated to cut into the soil. Immediately following the blade is an enlarged soil cavity. As the handle rotates, it drills down into the soil surface, and the soil sample of the soil layer to be collected can be introduced into the cavity.

[0003] In the prior art, there is a soil sampler disclosed in the authorized Chinese patent document publication number CN208206539U. The device can quickly collect complete undisturbed soil, and the undisturbed soil is sealed and collected in a sampling tube for direct experiment. The experimental data is more accurate and the experimental effect is good. However, it is necessary to manually hold the sampling handle and apply force downward so that the lower end of the sampling tube contacts the soil to be collected, and the soil to be collected is completely and quickly collected in the sampling tube. The sampling tube detachably connected to the push rod is pushed out by pushing the push rod through the sampling handle, and the sampling tube is separated from the push rod, which is time-consuming and laborious to use.

[0021] In this embodiment, the lower ends of the electric cylinders 31 are fixedly connected to both sides of the middle of the upper end of the moving trolley 1, the outer periphery of the lower end of the threaded rod 37 is slidably connected to the inside of the external threaded tube 34, the outer periphery of the discharge tray 39 is slidably connected to the inside of the sampling tube 35, and the lower end of the sampling tube 35 passes through the middle opening of the moving trolley 1 and extends.

[0022] Specifically, the electric cylinder 31 is started by the controller 4 to drive the sampling tube 35 to be inserted into the soil for soil sampling. After the sampling is completed, the external threaded tube 34 is rotated to remove the sampling tube 35, and the turntable 38 is rotated to cooperate with the threaded sleeve 2 36 and the threaded rod 37 to drive the discharge plate 39 to slide downward inside the sampling tube 35 to discharge the sampled soil from the sampling tube 35.
