[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION This invention is used for a take-out device for taking out the grain discharged from its outlet from a high position in a grain sorter in which a horizontally long sorting cylinder rotates around the horizontal axis. .

[0002]

2. Description of the Related Art A rotary sorting machine in which a large number of jar holes are provided on the inner surface of a horizontally long sorting cylinder is used to process (remove) grain (hulled rice) taken out from the outlet of the sorting cylinder. Is removed from a high position, the independent elevator is not necessary and the structure is simplified. For this reason,
A grain pumping device as shown in Japanese Patent No. 382 is provided at the outlet of the sorting cylinder.

[0003]

By the way, in the conventional device, as shown in the above publication, the inner end of the pumping vane provided in the pumping chamber has a ring-shaped partition wall at the outlet of the sorting chamber. It was provided so as to almost coincide with the inner end. Here, this sort of sorting apparatus sorts the grain by keeping the grain in the sorting chamber with this partition at a constant thickness. Therefore, if this partition wall is too low, grains flow out in an unsorted state, leading to poor sorting. On the contrary, if the partition wall is too high, a large amount of grains remain in the sorting chamber when the operation of the sorting machine is finished. on the other hand,
If the width is constant, the pumping wing's ability largely affects its height.

That is, in the conventional rotary sorter, the inner end of the pumping blade is aligned with the inner end of the partition wall, so that the main purpose is to reduce the amount of grains remaining in the sorting chamber when the operation is completed. Setting the height of the partition lowers it. Then,
Inevitably, the pumping wing also became lower, and its pumping capacity was insufficient. On the contrary, if this was set high so as to satisfy the pumping ability of the pumping blade, the partition wall inevitably became high, and a large amount of grains remained in the sorting chamber when the operation was completed.

EXAMPLES Next, examples of the present invention will be described. Figure 1
As shown in Fig. 3, the decapsulating part 1 is composed of a pair of rolls 3 that rotate inwardly, and most of the paddy rice that falls from the paddy funnel 2 on top of this is the rolls 3 and 3. It is designed to be peeled off. An exhaust air passage 4 is provided under the exhaust air passage 4. When brown rice, rice husks and rice husks flow in, light rice husks are sucked into the suction fan 5 on the left, and then discharged outside the machine through a dust pipe 6 extending upward. It is like this. The gutter 7 constitutes the bottom of the discharge air passage 4 and extends downward to the right,
The lower end is connected to the fried machine 8 so that the mixed rice consisting of brown rice and paddy rice is guided into the fried machine 8.

A sorting machine frame 9 is provided on the right of the removing unit 1. A horizontally long sorting cylinder 11 having a large number of jar holes 10, 10 on its inner surface is housed in the sorting machine frame 9 such that the inlet side at the right end is slightly higher than the outlet side at the left end. . Pumping cylinder 24 having an inward flange 24a at the left end
However, the right end is fixed to the selection cylinder 11 so as to cover the left end of the selection cylinder 11. Inward flange 25a on the right end
Similarly, the reinforcing cylinder 25 having the above is fixed to the right end of the selecting cylinder 11. A plurality of rollers 12, 12 ...
4 and the outer cylinder surface of the reinforcing cylinder 25 are contacted from below to support them,
The rotation causes the sorting cylinder 11 to rotate around the central horizontal axis.

The mixed rice receiving gutter 13 and the brown rice receiving gutter 15 are the sorting cylinders 1.
