DEVICE FOR SAMPLING CHOPPED STRAW FROM GRAIN COMBINE HARVESTERS Russian patent published in 2015 - IPC A01D75/00 G01N1/20 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agricultural machinery industry. The device for sampling chopped straw from grain combine harvesters comprises collectors, a retainer, a bracket and a control lever. The collectors are arranged in rows, the number of which in the transverse direction is determined by the header coverage and the selected number of the studied areas, and in the longitudinal - replication of sampling. The collectors are interconnected in longitudinal rows by means of flexible connections equal in magnitude, so that the total length of the row does not exceed the distance to the ground mass descent area on the stubble. The first collectors in each longitudinal row have easily removed connections on the holes in the rod-float leveller which is located perpendicular to the direction of the combine movement and retained by the retainer driven by the control lever.

EFFECT: invention provides a boundary separation of the comparable areas in sampling and reduction of the probability of failure of experimental equipment.
