Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a grain sorting device, and is used in an i-sliding machine, etc.

[Problem that the invention seeks to solve]

During harvesting, foreign substances such as stones larger than the rice grains may be mixed into the rice grains, but in order to remove these foreign substances during the hulling process, for example, the foreign substances are removed in the process before being fed to the sorting tube. If a special sorting mechanism is provided, the grain transfer process will be longer, and transfer stagnation will occur easily.
The structure is also complicated.

[Means to solve the problem]

This invention provides a paddy lifting groove (2) at the end of a rotary sorting tube (1) which separates brown rice and paddy while transferring mixed rice while rotating, and a paddy lifting groove (2) that can scoop up paddy. The grain sorting device is configured with a discharge port (3) for discharging larger foreign matter to the outside of the machine.

[Operation and effect of the invention]

If the sorting tube (1) is rotated and the mixed rice to be sorted is fed from the starting end of the sorting tube (1), the mixed rice will be transferred in the direction of the sorting end and will move in the rotational direction of the sorting tube (1). The paddy is sorted into brown rice that is scooped up to a high position and paddy that slides down on the way, and the paddy that reaches the paddy lifting ditch (2) at the end is scooped up by this paddy lifting ditch (2). Foreign matter such as relatively large stones, which are lifted out of the sorting tube, but reach the paddy lifting groove (2) along with the paddy, are not scooped up into the paddy lifting groove (2) and are removed from the sorting tube (1). ) is discharged outside the machine from the terminal discharge port (3), so not only brown rice and paddy but also relatively large foreign objects such as stone wires are sorted in the rotating sorting tube (1) that rotates integrally. Because of this, the flow of the sorted grains can be maintained smoothly, and the temperature of Hl can be kept at the oil temperature.

〔Example〕

In the example shown, there are a pair of deburring rolls (4) (4) at the front and back.
) is installed, and this deburring device (5) is installed.
) has a suction fan section (6) for sorting air in the entire front, and a sorting air path (7) communicating with this suction fan section (6), and a sorting air path (7) disposed in this air path (7). For mixed rice (8
), a box-shaped air selection chamber αci2 which is long in the front-rear direction is provided with a transfer helix etc. for brown rice (9) inside, and on the rear side of the tax scale @(5) on this air selection room aO, A sorting chamber α11 is provided which is completely enclosed in a rotary sorting tube (1) which is cylindrical and rotatable in the front-rear direction. In addition, in the center of this sorting tube (1), a pair of helical gutter for mixed rice and αS for brown rice, which are supported on both walls of front α2 and rear α3 of the sorting chamber (111), are installed next to each other. A plate-shaped brown rice receiving plate αOt whose tip is close to the inner circumferential surface of the sorting cylinder (1) is provided at the upper end adjacent to the upper end of both the ducts α(4) and α9, and the rotation of this plate αOt can be freely adjusted. At the upper end of each side wall of both gutter α4α9, a plate-shaped receiving plate for mixed rice and for brown rice (total) is attached at the tip, respectively, with the tip close to the inner peripheral surface of the sorting tube (1). In addition, at the rear end of the helical gutter for mixed rice α, a feed port α9 metal protrusion is provided to feed the mixed rice downward into the sorting tube (1). In addition, in both the sen gutter α and α9, there are a
A pair of transfer helices supported on both walls are provided.

A large number of depressions @1Jcυ into which unpolished rice can be fitted are provided almost on the inner circumferential surface of the rotary sorting cylinder (1) except for the front end, and the inner circumferential surface of this front end is provided with a plurality of depressions @1Jcυ into which paddy can be scooped. Cylinder (
1) A paddy lifting groove (2) along the axial direction is arranged on the inner circumferential surface, and the terminal edge of this sorting tube (1) forms a rising edge through which foreign matter such as masonry can overflow, and a discharge port ( 3) It has been established. Further, at the upper rear part of the dehulling device (5), there is provided a reduced paddy hopper (c) with a funnel-shaped receiving part at a position where the paddy falls into the paddy lifting groove (2). In addition, a paddy hopper (c) for supplying paddy to the dehulling rolls (4) (4) is also provided on the front side of this, and the wind sorting chamber is provided below the front end of the sorting tube (1). A discharge gutter is provided which is open to the outside of one side of αO and is formed with the front wall (2) portion facing forward.

In addition, (to) is removed by removal roll (4) (4),
Transfers the mixed rice that has been air-sorted in the sorting air passage (7) to the helical wire (8)
Thrower 1 which is fed into the rotary sorting cylinder (1) through
(A) is a thrower that discharges the brown rice sorted by the sorting cylinder (1) to the outside of the machine.

The paddy in the paddy hopper (2) is transferred to the dehulling rolls (5) (5)
The rice husks, etc. are removed by flowing down the sorting air channel (7) and transferred to the thrower via the transfer helix (8).
The mixed rice is transferred to the front part of the helical gutter α4 for mixed rice by □, and this mixed rice is further transferred to the rear by the transfer helical ■ and is fed into the rotary sorting cylinder (1) from the supply port (1 (3). The mixed rice in the cylinder (1) is transferred forward by the rotation of the sorting cylinder (1) and scooped up in the direction of rotation, and the brown rice that has fitted into the recess 1211 is transferred from a position beyond the receiving plate αdi to the brown rice helical gutter q9. It falls inside, is transferred forward by the transfer helix (A), flows down from the opening, and is transferred to the transfer helix (9).
The mixed rice that is discharged from the machine by the thrower through the machine, and that has fallen between the receiving plate α force and the receiving plate αG, is returned to the inside of the vessel through the spiral gutter α, and is further located in the upper layer of the mixed rice layer. The paddy that is left behind and reaches the front end of the sorting tube (1) is passed through the paddy lifting groove (
2), the reduced paddy is scooped up, falls into the receiving part of the bar, and is again supplied to the dehulling rolls (4) (4) from within this honono (c). At this time, foreign objects such as stones that reach the paddy lifting groove (2) along with the paddy roll or otherwise fail to fit into the paddy lifting groove (2) and fall from the discharge port (3) at the end. and is ejected from the aircraft.

In addition, the sorting cylinder part which completely forms this paddy lifting groove (2) may be constructed separately from the sorting cylinder part in which the recess CD is arranged, and may be configured to be integrally connected.
