ABSTRACT:
A sampler for extracting core samples from a mass of sugar cane. The sampler is mounted on a fixed or movable support which includes a plate member on which the cylinder of an operating jack is mounted.
The piston of the jack is secured at one end of a rod which has at its other end another piston for expelling core samples. A sleeve extends around a portion of the length of the rod and rotatably mounts a hollow cylindrical core cutter with a toothed cutting edge. A motor is mounted on the sleeve for rotating the core cutter. Selectively operable temporary securing fingers are provided on the sleeve of alternate engagement with a collar on the rod so that the sleeve, core cutter and rod are displaceable in unison by the jack for lowering and raising the core cutter into and out of a mass, and with the plate member for preventing the axial movement of the core cutter with respect to the support so that displacement of the rod displaces the other piston in the core cutter to expel the core sample. Alternatively an auxiliary jack is mounted in the sleeve for expelling the core samples and the rod is fixed to the sleeve and the selectively operable securing fingers are eliminated.
