Description

{Grain sampler}

The present invention relates to a grain sampler, and more particularly, it relates to a grain sampler which can insert a grain sampler into a saddle bag without requiring a large amount of force even if the length of the grain sampler is long enough to collect grains deep in the saddle bag. And to improve the multi-stage structure so that the grain sampler can be separated, so that the grain sampler can be easily carried and stored.

Generally, grains such as rice, barley, and soybeans are harvested and stored in a bag or bag of a certain unit, stored in a certain place, and then subjected to a quality grade determination process to be sold to general consumers. At this time, if the process of determining the quality grade is examined, a small amount of the grains contained in the bag is usually sampled at random and the grade is determined by visual inspection or the like. Such a grain is sampled by inserting a conventional grain sampler into a bag And the grain inserted into the grain sampler is taken out to the outside.

However, the conventional grain sampler has a disadvantage in that it is impossible to collect grains deep in the grains contained in the saddle bags and thus only the grain at the upper part can be collected, so that it is difficult to obtain a fair and reliable sample. In order to solve this problem, the worker compensates the above disadvantages by collecting samples by inserting several places on the short side several times in consideration of the asymmetrical width and width of the turret.

However, the disadvantages mentioned above can be solved to some extent by increasing the length of the grain sampler. However, in this case, since the length of the grain sampler becomes long, a considerable load is put on inserting the grain sampler into the saddle bag, This is a difficult disadvantage and is not used in the field.
