Detailed Description

Description of the working principle:

according to the utility model, through arranging the mutually matched slide ways, the baffle 4 is positioned at the opening 3 before sampling, so that the opening 3 is in a closed state, the handle 1 is held to push the barrel body 2 to the material, the baffle 4 is opened, the spiral regulator 6c is adjusted to enable the guide plate 5 to slightly extend out of the opening 3, the sampling amount can be adjusted according to the extension distance of the guide plate 5, and the spiral regulator 6c is screwed after the extension distance of the guide plate 5 is confirmed. Holding handle 1 clockwise rotation, the material passes through guide plate 5 and gets into the sample chamber, can take a sample, when the sample finishes, adjust back in the barrel with guide plate 5, return baffle 4 appearance to opening 3 department, make baffle 4 be in the closed condition, lift handle 1 upwards and can take out the sampler, open baffle 4 after taking out the sampler, pour the material into to the sample bag of preparing from opening 3 department, available distilled water washs after the use, dries, repeatedly usable.

The present invention provides a novel material sampler, and the technical solution of the present invention is further described in detail below with reference to the accompanying drawings to better understand the present invention, but the following examples do not limit the scope of the present invention.

Example 1

The measured angle of repose of a certain R material is 49.8 degrees, the flowability is poor, the conventional sampler and the sampler of the utility model are adopted to respectively carry out random sampling, the volumes of sampling cavities of the two samplers are similar, and the conventional sampler is a double-cylinder shaft adjusting sampler.
