DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for treating grain with branch stalks mixed into rice grain.

[0002]

2. Description of the Related Art Conventionally, when a variety of varieties that are particularly difficult to shatter is harvested by a combine or the like, grains with branch stalks are mixed in the grain, and the grain is transferred to a transport route such as a dryer or a huller in a later process. There are problems such as clogging. In order to solve this problem, various measures have been taken to improve the threshing treatment action in the handling room, and since there are many grains with branch stumps in the second reduced product, a dedicated processing cylinder is provided. However, the effect is not enough. Therefore, as a processing device for grains with branch veins, a single device as described in Japanese Utility Model Publication No. 4-141117 has also appeared. However, this one has a slit narrower than the rice grain on the peripheral surface of the cylinder,
It removes the branch stalks that have entered the slits and has a low processing capacity, and the rice husks are not discharged to the outside from the slits but are discharged to the cylinder. There is a disadvantage that the action is repeated and the rice grains are damaged.

[0003]

SUMMARY OF THE INVENTION Accordingly, the present invention is to provide an apparatus which solves the drawbacks of the prior art described in the preceding paragraph and which does not damage rice grains while greatly increasing the processing ability of the resection of branch branches. The invention has been made for the purpose of.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a spiral cylinder in a vertical cylindrical body having a large number of branch incision holes formed on the peripheral surface thereof, the size of which allows passage of rice grains. Rotation to rotate in the direction of the arrow (a) where the rice grains are wound and wound up
A body is provided , an interval between the outer peripheral edge of the spiral and the inner peripheral surface of the cylindrical body is set so that the rice grains can flow down, and the cylindrical body is surrounded by an outer cylinder to form a falling path around the outer periphery of the cylindrical body. And a supply port is provided in the upper part of the cylindrical body.

[0005]

According to this construction, when the rice grain mixed with the grains with branching is supplied from the supply port into the cylindrical body, it is pushed up by the spiral wound around the rotating rotating body and is stirred while being stirred by the outer periphery of the spiral. It flows from the top to the bottom between the inner peripheral surface of the cylindrical body, and in the process of the flow, the rice grain is discharged from the branch incision hole. It is discharged from the branch incision hole due to the cutting action of being cut off from the grains, and those not discharged from the branch incision hole are taken down the cylinder and taken out, and the discharged thing flows down the falling path. As they are taken out, the rice grains are discharged in the process of flowing downward, so that the processing capacity is increased, and the rice grains are not repeatedly subjected to the operation of removing the branch infarct, so that no damaged grains are generated.
