Description

Technical Field

[0001] The utility model relates to the technical field of plastering gypsum processing, in particular to a sampling device with a telescopic adjustment structure. Background Art

[0002] Plastering gypsum is mainly used for plastering various indoor walls of buildings. It has the advantages of abundant raw materials, low price, simple production process, convenient construction, good thermal insulation effect, etc. It is a newer, more environmentally friendly and more economical national key promotion material. In the production process of plastering gypsum, a variety of different raw materials need to be put into the mixing bin in proportion and mixed evenly. After the mixing is completed, the components of the prepared plastering gypsum need to be sampled and tested to ensure that the finished plastering gypsum meets the use standards.

[0003] The prior art CN 216207834 U discloses a sampling device for the production of lightweight plastering gypsum, which includes an annular shell, an elongated piston, a sealing ring and other components. Although the utility model can drive the elongated piston to move left and right through a pushing mechanism to collect the plastering gypsum, and the elongated piston can tightly fit with the inner wall of the annular shell through the sealing ring when moving left and right to seal the mixing chamber and the annular shell, the utility model and the traditional sampling device can only sample the plastering gypsum in the outer ring part of the inner cavity of the mixing chamber, but cannot go deep into the mixing chamber to sample the plastering gypsum in the deep, and cannot accurately sample the plastering gypsum at the corresponding depth position. Therefore, the sampling of the existing sampling device has great limitations and is generally practical, so there is still room for improvement. Utility Model Content
