SAMPLING DEVICE FOR SILAGE Russian patent published in 2013 - IPC G01N1/04 G01N1/08 

FIELD: agriculture.

SUBSTANCE: sampling device comprises a probe with a sharp-edged cutting edge in the lower part, a flange with a chamfer in the upper part, which is attached coaxially to the rod of a smaller diameter with a measuring scale, and a sample extractor. The cylindrical probe in the lower part is provided with two oval cutting bits with sharp-edged cutting edges. The flange in the upper part with the manufacturing hole made perpendicular to the longitudinal axis of the sampling device is attached to the bar consisting of rods of circular section which are screwed in one another with dimensional manufacturing holes. The openings are made on the surface of the rod in every 500 mm from the oval cutting bits of the probe, and their diameter is equal to diameter of the probe extractor - a rod with a conical groove. Moreover, between the cutting bits and the flange on the probe surface two longitudinal grooves are arranged opposite each other.

EFFECT: reduction of the labour intensity of sampling by providing easier penetration of the sampling device in the estimated mass, providing the possibility of batch sampling from a depth of 1,5-2 m, ensuring easy removal of the sampling device at deep layers of silage.
