外へ取り出されるものである。Next, the mixed rice is scooped up by the pot hole of the rotary sorting tube (11) which is rotating clockwise in Figure 2, and the fine brown rice falls into the finishing rice gutter (16), where it is separated from the paddy and other parts. The mixed brown rice falls into the supply gutter (14) and is sorted.
The unsorted mixed rice that has fallen into the supply gutter (14) is fed again into the rotary sorting tube (11) from the conveyance end of the feed gutter (14) by the feed helix (13), and is re-sorted. In addition, the finished rice that has fallen into the downstream gutter (16) is conveyed to the finished rice downstream tube (17) by the downstream Miki screw (15), and then passed through the finishing rice stream grain plate (18) and is then transferred to the final rice receiver. While falling into the gutter (19), the grains are sorted by the sorting wind and taken out of the machine by the grain lifting machine (20).

6) rotates downward, the small diameter linking part (30) and the large diameter linking part (31) also rotate in the -F direction, and the linking member (2
5) also rotates downward due to its own weight, and the paddy supply control valve (26)
When the hulling operation in the hulling section (1) is on track, the grain 1 end flow adjustment lever (27) is moved to the hulling start position (B). ) and then rotate it further downwards. Then, as shown in Fig. 4, the small-diameter linking part (30) on the finishing Miki adjustment lever (27) side becomes linked to the paddy supply adjusting long arm (29) on the linking member (25) side, and the finished rice By rotating the paddy supply control valve (26) by a small amount compared to the amount of rotation of the control lever (27), the hulling work can be performed while finely adjusting the rotation of the paddy supply control valve (26). It is something.

行うことができるものである。In a state where the finished rice adjustment lever (27) is rotated from the sliding start position (B) to the valve closing position (A), that is, in a state where the paddy supply adjustment valve (26) is controlled to be opened small, The large diameter connecting part (3) on the finishing rice adjustment lever (27) side
1) comes into contact with the paddy supply adjustment short arm (28), rotates the paddy supply adjustment short arm (28) by a large amount compared to the amount of rotation of the rice adjustment lever (27), and the paddy supply adjustment valve closes. (26
) is quickly rotated to the closing side, and although the rotation operation range of the finished rice adjustment lever (27) is reduced, the paddy supply adjustment valve (26) is relatively small during hulling operation. When the paddy supply control valve (26) is opened wide, the paddy supply control valve (26) is moved and adjusted by a small amount relative to the amount of operation of the two-meter lever (27), and the paddy supply control valve (26) is finely controlled. It is something that can be done.

Claims

[Scope of Claims] [1] A rice hulling machine having a shedding section (1) and a rotating sorting cylinder (11) having a number of potholes on its inner circumferential surface,
A grain control valve (16a) is attached to the grain gutter (16) located in the rotary sorting cylinder (11) and receiving the sorted grains, so that the grains to be sorted in the rotary sorting cylinder (11) are The layer thickness detection sensor (23) for detecting the grain amount and the paddy supply control valve (26) of the husking section (1) are interlocked and connected via the interlocking member (25), and the grain control valve (16a) is Opening/closing the paddy supply control valve (26) attached to the adjustment operation tool (27) side between the adjustment operation tool (27) and the interlocking member (25) or the paddy supply control valve (26) in a wide open state. The small diameter linkage section (
30) and a large-diameter linking portion (31) that controls opening and closing of the small-opening state of the paddy supply control valve (26).
