DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for collecting sample grains from grain stored in a rice cabin.

[0002]

2. Description of the Related Art Conventionally, a stirrer for rotating a vertical auger around a central portion of a rice cabin while rotating the same in a rice cabin, and a sampling device for extracting sample grains from stored grains are known. Are publicly known.

[0003]

However, the conventional sampling apparatus is fixed to the upper part in the rice cabin, and the extraction of the sample grains from the stored grains is limited to one place. The disadvantage is that it is difficult to obtain accurate data because data is obtained from the sample grains collected from the location.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned drawbacks, the present invention is directed to a rice rice stirrer for stirring grains stored therein and a sampling device for extracting sample grains from the stored grains. The cabin, in which the collecting device is movable and can be taken out from several places in the rice cabin, makes the data relating to the stored kernels accurate and allows for appropriate post-processing.

[0005] Further, the stirring device is suspended by a rotatable support rail centering on a central portion in the rice cabin, and a sampling device is provided on the opposite side of the support rail. Since it is provided on a guide rail that rotates around the rotation axis and is free to move along the guide rail, the two devices can be rotated in a well-balanced manner without interfering with each other and with a stirring action and from several places. Sample particles can be taken out.

The sampling device includes a hose drum rotated by a hoisting motor, a suction hose wound around the hose drum, and a suction cylinder connected to the tip of the suction hose. The suction cylinder is provided with a grain detector for detecting a collision against the grain surface slidably up and down by a predetermined amount, so that the tip of the suction cylinder reliably enters the surface layer of the stored grains. The removal of sample grains does not fail.

[0007] A limit switch is turned on by sliding the grain detector upward to activate a hoisting motor, and a suction hose is hoisted to return the sampling device to a standby state. Thus, when the sample grains are sucked in, they are automatically wound up and work efficiency is improved.

Further, by forming the grain detector in an umbrella shape, the grain detector strikes the stored grain surface stably and the suction by the suction cylinder is improved.
