Description

Detailed Description of the Invention [Industrial applications]

The present invention is used for a huller equipped with a rotary sorting device for pumping and separating brown rice having a small grain in a pot hole higher than that of large grain rice by rotating a sorting cylinder.

[Prior art]

In this hulling machine, it is necessary to replace the grain with a different size of the jar hole of the sorting cylinder according to the difference in size of rice grain to be sorted, length, etc. In addition, when used for a long period of time, the jar hole is clogged with dust and the sorting performance deteriorates. Therefore, it is necessary to remove the sorting cylinder from the sorting case for periodic cleaning. As such a conventional technique, Japanese Utility Model Publication No. 58-108182,
There are Japanese Utility Model Laid-Open No. 59-24136 and US Pat. No. 2216914. Japanese Utility Model Laid-Open No. 58-108182 discloses a structure in which a selection cylinder and an internal gutter are removed at the same time.
No. 36 gazette has a configuration in which a gutter and a supply gutter for brown rice are arranged inside a sorting cylinder, and a rotatable sluice valve is provided on the tip side of the gutter, but the sorting cylinder is removed from the machine body. No consideration, and U.S. Pat.No. 2,216,914 relates to grain cleaners, in which a stationary cylindrical sieve is covered with a casing and the stationary cylindrical sieve can be removed while leaving the inner rotating body in the fuselage, Alternatively, in the embodiment in which the rotary sieve is covered with the casing, when the rotary sieve is removed, the spoke wheels inside and the internal spiral conveyor are also taken out integrally with the selection cylinder.

[Problems to be Solved by the Invention]

In the prior art, when removing the sorting cylinder rotating around the horizontal axis from the sorting case, the gutter and the transfer spiral that do not need to be removed and the rear plate that is a supporting member for these are removed, and the removed member is removed. In addition to the heavy transportation, it was necessary to remove the inner gutter and the transfer spiral from the sorting cylinder again to clean the inside of the sorting cylinder, which was troublesome.

[Means for solving problems]

In order to solve the above problems, the present invention is provided with a large number of pot holes 4, 4, ... On its inner peripheral surface, is long in the front-rear direction, and the rear side is the sorting start end side and the front side is the sorting end side. The sorting cylinder 5 which rotates around the horizontal axis, the four driving rollers 7,7, ... which support the front and rear ends of the sorting cylinder 5 from below, and the sorting cylinder 5 which covers the sorting cylinder 5 and is provided behind the removing device 2. Sorting case
8,11,19,20 and brown rice pumped along the longitudinal direction in the selection cylinder 5 along the longitudinal direction thereof, and the received brown rice is the start side of the selection behind the selection cylinder 5. From the front to the sorting end side on the front side, which is picked up by the spiral 25, and a gutter 26 provided in parallel with the gutter 26 for sorting grains to be sorted.
Is equipped with a supply gutter 28 for phase-shifting from the sorting end side on the front side to the sorting start side on the rear side with a helix 27, and a receiving trough 26, a helix 25 and The front end portions of the supply gutter 28 and the spiral 27 are attached, and the rear end portions thereof are detachably attached to the rear plate 11 on the rear side far from the removing device 2 in the sorting case. Case, receiving gutter 26, spiral 26 and supply gutter 28
・ By removing from the rear end of the spiral 27,
A rotary sorting type huller characterized in that it is configured so that only the sorting cylinder 5 can be pulled out rearward while the front ends of the spiral 25 and the supply trough 28 / the spiral 27 are still attached to the front plate 8. And

[Action]

Since the present invention is configured as described above, most of the paddy rice is scraped off by the removing device 2, and the rice husks are mixed with brown rice and a small amount of paddy rice. At the spiral 27, it is transferred from the sorting end side on the front side of the machine body to the sorting start end side on the rear side, and is supplied to the sorting start end side on the rear side of the sorting cylinder 5. Then, since the sorting cylinder 5 is rotating around the horizontal axis, mixed rice is pumped up in the pot holes 4, 4, ..., However, since long paddy rice has a low fitting ratio in the pot hole 4, it is at a relatively low position. On the other hand, since the rice husks are peeled off and the rice grains are small, the rate of fitting into the jar hole 4 is deep, and it is lifted to a high position and dropped from the jar hole 4 and received by the gutter 26, It is separated from the paddy rice that dropped in the lower part. Then, the brown rice received by the gutter 26 is transferred by the spiral 25 from the rear side of the rear side of the selection cylinder 5 to the front side of the selection end and then taken out. When changing the type of paddy rice to be removed and replacing it with a sorting cylinder 5 having different jar holes 4,4, ..., or when cleaning the inside of the sorting cylinder 5 (jar holes 4,4, ...), Like
That is, the rear plate 11 is removed from the sorting case, and also removed from the rear part of the gutter 26 / helix 25 and the supply gutter 28 / helix 27.
Then, the rear side of the sorting case is opened, and the gutter 26, the spiral 25, and the supply gutter 28, which are located inside the sorting cylinder 5,
The spiral 27 is in a cantilever state in which only the front plate 8 of the sorting case is supported, and only the sorting cylinder 5 is pulled out rearward from this open large hole.

【effect】

As described above, according to the present invention, the sorting cylinder 5 is independently pulled out from the sorting case while leaving the receiving gutter 26 / helix 25 and the supply gutter 28 / helix 27 therein in the sorting case. Compared with the conventional one in which the selection cylinder 5, the gutter 26 / helix 25, and the supply gutter 28 are removed together with 11, only the selection cylinder 5 is removed, which is lighter and easier to work. Further, in the conventional case, after the removal from the selection case once, the selection cylinder and the internal gutter had to be removed again, and the removal of the selection cylinder was extremely troublesome. Since the selection cylinder 5 is taken out only by removing 11, the troublesomeness is eliminated.
