1results about How to "Reliable sampling" patented technology

This utility model relates to the field of concentrate powder sampling technology, specifically to a ton-bag concentrate powder sampling device for use during the freezing period in extremely cold regions. One end of the sampling probe is provided with an incised perforated tooth pattern, and the other end is provided with an annular limiting buckle. The sampling probe has a strip-shaped pressure relief groove area, which is arranged along the axial direction of the sampling probe. Two anti-freeze hydraulic cylinders are arranged in parallel. The piston rod ends of the two anti-freeze hydraulic cylinders are connected to the push plate, and the bases of the two anti-freeze hydraulic cylinders are mounted on the fixed base plate. A movable sampling frame is provided between the two anti-freeze hydraulic cylinders, one end of which is connected to the push plate. The movable sampling frame has multiple pull-out slots that match the annular limiting buckle. Both the push plate and the fixed base plate have grooves that allow the sampling probe to pass through. This utility model enables efficient, accurate, and reliable sampling of ton-bag concentrate powder in extremely cold regions.
