METHOD OF TAKING PLANT SAMPLING AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2014 - IPC G01N1/04 

FIELD: agriculture.

SUBSTANCE: group of inventions relates to the field of technology of cyclic taking of plant samples from clamps, pits, trenches, haystacks, mows and other repositories in agriculture in determining quality indicators of feed and can also be used when taking samples of other non-free-flowing materials, such as peat, soil and snow. The method of taking plant samples is that during rotation of the device of taking the plant samples the auger retraction of the cutting crown into the feed monolith and the auger feeding of the cut-out feed in the storage unit are provided. At that the recording by the fluid content gage of the volume of the taken plant sample is provided, as well as its removal from the moving storage unit. The device of taking the plant samples comprises a shaft with a cylindrical part of the auger and a lower conical auger tip. In the area of the base of the tip the cutting crown is installed and secured with at least one pin, with mortices-hooks at the upper part, by which it docks with projections of the storage unit when turning its projections in the mortices-hooks of the crown in the opposite direction with respect to rotation in cutting the monolith of the feed. The storage unit has free rotation and movement along the shaft with the cylindrical part of the auger for releasing the crown from the hook and extracting the sample taken. In addition, the storage unit is equipped with a mechanical fluid content gage of the volume of the sample taken in the form of a plate resting on the cylindrical part of the auger, connected to the recording tube, sliding along the smooth part of the shaft with the cylindrical part of the auger.

EFFECT: monitoring the filling of the storage unit, which enables to provide the accuracy of determining the volume of the sample taken at a given depth.
