Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for a cylindrical rice hull sorter equipped with a rotary sorting device for pumping and separating brown rice having a small grain in a pot hole higher than large grain rice by rotating a sorting cylinder. .

[0002]

2. Description of the Related Art This cylindrical type hull sorting machine replaces a sorting cylinder with a different pot size according to the size of rice grains to be sorted and the length of the rice grain. When used for a long period of time, the pit hole becomes clogged with dust and the sorting performance deteriorates. Therefore, it is necessary to remove the sorting cylinder from the sorting case for regular cleaning. As such a conventional technique, there is Japanese Utility Model Laid-Open No. 3-178378.

[0003]

In the above prior art, when removing the sorting cylinder rotating around the horizontal axis from the sorting case, the brown rice gutter and the transfer spiral inside the sorting cylinder are sorted. It is convenient because only the selection cylinder can be removed while it is attached to the table. However, due consideration has not been given to the relationship between the cylindrical flange on the front side of the selection cylinder and the drive roller attached to the drive roller shaft. However, there was a problem that the positioning with the drive roller could not be performed smoothly. Therefore, the present invention is intended to solve such a problem.

[0004]

The present invention has taken the following technical means in order to solve the problems of the prior art. That is, according to the present invention, a large number of jar holes 4, 4, ... Are provided on the inner peripheral surface, which is long in the front-rear direction and rotates around the horizontal axis with the rear side as the selection start end side and the front side as the selection end side. 5, four driving rollers 7, 7 ... Supporting both front and rear ends of the sorting cylinder 5 from below, and a sorting case covering the sorting cylinder 5 and provided behind the removing device 2. 8
And, in the selection cylinder 5, the brown rice pumped along the longitudinal direction in the pot holes 4, 4, ... Is received and the received brown rice is transferred from the selection start end side on the rear side of the selection cylinder 5 to the selection end side on the front side. Unpolished brown gutter 26 that is transferred by brown rice spiral 25 and taken out
And a supply spiral 27 that is provided in parallel with the brown rice gutter 26 and transfers the grains to be sorted from the sorting end side on the front side of the sorting cylinder 5 to the sorting start end side on the rear side. The brown rice gutter 26 and brown rice spiral 25 on the front plate 8a on the front side of the sorting case 8 close to the removing device 2 are provided.
And the front ends of the supply gutter 28 and the supply spiral 27 are attached, and the rear ends of the supply gutter 28 and the supply spiral 27 are detachably supported by the rear plate 11 on the rear side far from the removing device 2 in the sorting case 8. After this, the rear plate 11 is selected, a case 8 and a brown rice gutter 2
6. By separating the brown rice spiral 25, the supply trough 28, and the supply spiral 27 from the rear end portions, the front ends of the brown rice receiving trough 26, the brown rice spiral 25, and the supply trough 28 and the supply spiral 27 are front plates 8.
In the configuration in which only the selection cylinder 5 is pulled out rearward while being attached to the a, the cylindrical flanges 6 and 6 provided on the front and rear outer peripheral portions of the selection cylinder 5 are attached to the selection cylinder 5 respectively. Of the left and right drive roller shafts 21 and 21 are rotatably supported by front and rear drive rollers 7, 7, ... On the rear side of the drive rollers 7 and 7 on the front side of the drive roller shafts 21 and 21, a front conical portion 32 having a larger diameter toward the rear side and a rear end of the front conical portion 32 are connected. This is a configuration of a sorting cylinder attaching / detaching device of a rotary type hull sorting machine, characterized in that a guide collar 31 having a small-diameter rear side tubular portion 33 is provided.

[0005]

Since the present invention is constructed as described above, most of the paddy rice is scraped off by the removing device 2 to remove the chaff.
The mixed rice in which brown rice and some unhulled rice are mixed is transferred from the selection end side on the front side of the machine to the selection start side on the rear side by the supply spiral 27 in the supply gutter 28 in the selection cylinder 5, and the selection cylinder 5 It is supplied to the rear side of the sorting start end.

Then, since the selection cylinder 5 is rotated around the horizontal axis by the drive rollers 7, 7, ... And the cylindrical flanges 6, 6, the mixed rice is pumped up in the jar holes 4, 4 ,. The long rice paddy has a low rate of fitting into the jar hole 4, so it falls at a relatively low position, while the brown rice has a small size due to the peeling of the rice husk, so the ratio of burial hole 4 into the jar hole 4 is deep and high. It is lifted up to the position and falls from the jar hole 4 and the brown rice gutter 2
It is caught at 6 and separated from the paddy rice that dropped down. Then, the brown rice received by the brown rice receiving trough 26 is transferred and taken out by the brown rice spiral 25 from the rear side of the selection start end on the rear side of the selection cylinder 5 to the front side of the selection end.

The kind of paddy rice to be removed changes, and
When replacing the selection cylinders 5 having different sizes, etc., or when cleaning the jar holes 4, 4, ... Of the selection cylinders 5, the following is done. That is, the rear plate 11 is removed from the sorting case 8, and the brown rice receiving gutter 26, the brown rice spiral 25, and the supply gutter 28 are provided.
・ Remove from the rear of the supply spiral 27. Then, the rear side of the sorting case 8 is opened, and the brown rice receiving gutter 26, the brown rice spiral 25, and the supply gutter 2 located in the sorting cylinder 5 are provided.
8. The supply spiral 27 is in a cantilever state supported only by the front plate 8a of the sorting case 8, and only the sorting cylinder 5 can be pulled out rearward from this open large hole and removed. When the selection cylinder 5 is attached, the selection cylinder 5 is moved from the rear side to the front side so that the cylindrical flanges 6 and 6 on both the front and rear sides of the selection cylinder 5 are aligned with the front and rear drive rollers 7 and 7. To install.

When the cylindrical flange 6 on the front side of the selection cylinder 5 is attached to or detached from the drive rollers 7, 7 on the front side, the movement between the drive rollers 7, 7 and the guide collar 31 is smoothed. , Positioning becomes easy.
