Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention is directed to a demounting section, a wind selecting section, and a sorting cylinder in which a large number of jar holes are formed on the inner peripheral surface and rotatably laid horizontally. TECHNICAL FIELD The present invention relates to a brown rice removing device for a rotary-selecting grain hulling machine, which is configured by combining a brown rice obtained by deaeration by inserting a gutter and a pot-hole type sorting section for sorting mixed rice of paddy.

(B) Conventional Technology As for the rotary sorting and hulling machine constructed by combining the removing section, the wind selecting section and the pothole type sorting section as described above, as a conventional technique, for example, the actual development 57-55539. As disclosed in the publication, the power of the de-air selection section and the power to the pot-hole type sorting section are independent of each other, and the rotation speed of the pot-hole type sorting section, that is, the sorting cylinder, is different from that of the other de-sectioning sections and the wind sorting. The rotational speed is appropriately changed regardless of the parts.

This is because when the flow rate of the mixed rice fed into the sorting cylinder is small at the beginning or near the end of the hulling work, the paddy is lifted up in the gutter to lower the sorting purity. In order to prevent this, the rotation speed of the sorting cylinder is reduced to weaken the lifting effect of the pothole.

(C) Problems to be solved by the invention However, even if the rotating speed of the sorting cylinder is slowed down, if the amount of mixed rice flowing in the sorting drum becomes too small, it is inevitably raised in the trough. In such a case, the present invention shifts the rotation of the selection cylinder at a low speed and the one lifted in the gutter is taken out of the machine because the selection purity of the unpolished rice deteriorates. It is possible to circulate in the machine without deteriorating the sorting purity, and also to take out the machine and circulate inside the machine in connection with the shifting operation of the sorting cylinder so as to eliminate operational mistakes and prevent troubles. It was created for the purpose of trying to

(D) Means for Solving the Problems Therefore, according to the present invention, a gutter is provided in a sorting cylinder in which a desorption part, a wind selection part, and a large number of jar holes are formed on the inner peripheral surface so as to be rotatably mounted horizontally. The following means are intended to be applied to a rotary selection hulling machine which is composed of an urn-type selection section for inserting and selecting mixed rice of brown rice and paddy.

That is, the rotation speed of the sorting cylinder is adjustable, and a switching valve for in-machine circulation is provided between the trough and the take-out passage of the brown rice sorted by the pot-hole type sorting unit to change the rotation speed. The switching valve is operated in connection with the speed change operation between the high speed and the low speed so that the brown rice is switched between the removal from the machine and the circulation inside the machine.

(E) Action With this configuration, if the rotation speed of the sorting cylinder is changed to a high speed, the sorting cylinder rotates at a rotation speed within a predetermined range, and the switching valve is connected to the gutter and the take-out passage in connection with this operation. Of the de-winded mixed rice of brown rice and paddy, the brown rice is picked up by the pot hole and taken out of the machine through the take-out passage from the trough. When the flow rate of the mixed rice supplied into the sorting cylinder is too small, such as immediately after the start or just before the end, the rotation speed of the sorting cylinder is changed from high speed to low speed. It is switched to the one that cuts off the pick-up passage and the pick-up passage, slowing down the rotation speed of the sorting cylinder to weaken the lifting action by the pothole, and the thing lifted up in the gutter is taken out of the machine from the take-out passage. Gen is taken out as it circulates inside the aircraft without being taken out. Rice is not mixed in the rice.

(F) Example Hereafter, the present invention will be described in detail with reference to the accompanying drawings.

It is led out to the rear part of the machine, flows down the take-out passage (17), removes scrap rice in the wind-selecting passage (18), and is fed horizontally by the brown rice take-out gutter and lifted up by the brown rice thrower (20) into an appropriate container. It is stored.

The paddy left behind from the unpolished rice in the sorting cylinder (12) is scooped up by several buckets (21) evenly distributed on the inner peripheral surface of the front end of the sorting cylinder (12) to reach the upper side. Then it falls and is received by the paddy gutter (22) and returned to the paddy tank (2). If it is not lifted up to the gutter (15) by the lifting action of the pit (11), the transfer gutter (13) ), It is sent to the rear side and supplied again into the sorting cylinder (12).
