Problems to be Solved by the Invention Therefore, in the present invention, a bucket is arranged on the outer circumferential surface of a sorting tube that is rotatably suspended horizontally by forming a large number of depressions on the inner circumferential surface that constitutes the pot-hole type rotary sorting section. By using its own rotation to lift up mixed grains of brown rice and paddy to be supplied to the pot-hole type rotary sorting section, a separate grain lifting machine can be installed, and the shape and installation condition of the bucket can be improved. It was devised for the purpose of lifting the mixed grains by the rotation of the sorting cylinder itself and improving the lifting process.

Means for Solving the Problems Therefore, the present invention is a grain rotary sorting huller that combines a dehulling section, a wind sorting section, and a pot-hole type rotary sorting section. A pothole-type rotary sorting section is arranged above and below, and a pothole-type rotary sorting section is adjacent to the removal section and the wind sorting section, and a large number of depressions are formed on the inner peripheral surface constituting the pothole-type rotary sorting section. A bucket that rotates integrally with the sorting tube is disposed on the outer circumferential surface of the adjacent end of the sorting tube that is rotatably hung horizontally, and the bucket protrudes a considerable amount from the end of the sorting tube. The mixed grain of brown rice and paddy after deairing is fed into the sorting cylinder through a guide plate and a supply plate, which have a sloped bottom and are diagonally installed between the bucket and the removing part within the rotating path of the bucket. It is intended to be structured as follows.

Function With this configuration, the mixed grains of brown rice and paddy that have been de-air-sorted by the de-sheathing and wind-sifting parts are lifted by the rotation of the bucket that is evenly distributed on the outer circumferential surface of the sorting tube. It is then fed into the sorting cylinder via a guide plate and a supply plate.

The supplied mixed grains are then sorted into brown rice and paddy by the scooping action of the hollows.

The supply gutter 15 has a drop opening (not shown) for supplying grains into the sorting tube 9.

Incidentally, numerals 18 and 19 are partition plates whose lower edges are pivotally supported on the grain receiving side of the sorting cylinder 9 which rotates in the direction of the arrow A of the receiving gutter 14 and the feeding gutter 15, so that the inclined posture can be changed freely.

Numerals 20 and 21 are arranged at equal intervals on the outer peripheral surface of the front end, that is, the adjacent end of the sorting tube 9, and on the inner circumferential surface thereof, respectively, and are integrally attached to the sorting tube 9. The bucket bag 20 is attached to the sorting tube 9 so as to protrude forward by a considerable amount M from the front end of the sorting tube 9.

Reference numeral 10a denotes a concave groove plate formed in a semicircular shape along the rotation of the bucket bag 20, and its lower part is connected to the sink plate 10.

Reference numerals 22 and 23 denote a guide plate and a supply plate, which are diagonally arranged to face each other between the removal part A and the rotating locus of the bucket 20, and the lower part of the guide plate 22 is bent downward to form a return gutter 24, which will be described later. A notch 25 is provided in the upper part of the supply plate 23 through which the bucket 20 passes, and the lower part looks into the supply gutter 15 and is formed by the guide plate 22 and the supply plate 23 to form a supply passage. form R. The mixed grain bucket 20 has a bottom N formed as a slope.

There is an annular blocking wall 26 on the outside of the paddy bucket 21.
The return gutter 24 is provided obliquely from the front side passing below the guide plate 22 toward the rear and upper side to receive the paddy discharged from the bucket 21 and return it to the paddy tank 2.

Therefore, the paddy that falls one after another from the paddy tank 2 is removed by a pair of derolls 3, and dust such as rice husks and rice grains are removed by the sorting wind of the wind selection path 7, and the removed brown rice and paddy are separated. The mixed grains flow down on the sink plate 10 and are scooped up by the mixed grain bucket 20 which rotates in the direction shown by arrow A together with the sorting tube 9, and are discharged one after another from the bucket 20 that reaches the top level. be done. The mixed grains released at this time collide with the back surface of the bottom rotating just in front of it, as shown by arrow B in Figure 3, but since this bottom N is formed on a slope,
Some are guided in the direction of the arrow C along this slope and fall directly onto the guide plate 22, while others fall directly onto the supply plate 23.
