Abstract

A grain sampling probe device for insertion into grains comprises an elongated grain probe element which contains a plurality of openings extending along its length and a plurality of retaining brackets extending outwardly to define a passageway. Mounted integral to the grain probe is a hydraulic cylinder which is attached to a gate member, having a plurality of openings therein, which is slidably positioned within the passageway between the retaining brackets and the probe. The hydraulic cylinder selectively moves the gate member between an open position wherein the grain passes through the plurality of openings into the grain probe and a closed position wherein the openings are closed and the grain is sealed within the probe. A suction device is attached to the end of the probe to remove the collected grain after each sampling operation is completed.

Claims7

Dependent claims

A sampling device for insertion into a body of confined grain, including in combination:

a tubular probe member having a closed lower end with an opening therein and a plurality of vertical spaced openings extending the length thereof,
gate means having a plurality of sectional spaced openings therein, said gate means being engageable with said tubular probe member and movable from a closed position wherein said gate means substantially closes said plurality of vertical spaced openings in said probe member to an open position wherein said vertical openings on said gate means are in alignment with said vertical spaced opening on said tubular probe member,
bracket means mounted on the end of said tubular probe member opposite the closed lower end,
probe mounting means attached to said bracket means to hold said tubular probe member in substantially a vertical position,
suction means operatively connected to said opening on said closed lower end of said probe member, and
control means for operating said probe mounting means in positioning said probe member in the body of the confined grain, said control means further moving said gate means between a closed and an open position to permit grain to fill said tubular probe member and actuating said suction means to withdraw the collected grain from said probe when the same has been withdrawn from the body of the confined grain.
