Abstract

PROBLEM TO BE SOLVED: To obviate the occurrence of variations in sepn., to enable the execution of uniform sepn. and to substantially prevent the vibration at the time of rotating husking rolls by forming the width of the husking surfaces of these husking rolls to approximately the same width as the width of a winnowing path existing below these rolls and supporting husking roll shafts from both sides of the operation side and transmission side of a machine body. SOLUTION: The husking section A of a husking separator comprises a paddy hopper 6, a shutter plate 7, a pair of the husking rolls 1a, 1b and a delivery roll 8. At this time, the one husking roll 1a is pivotally supported by a husking roll shaft 2a and the other husking roll 1b is disposed freely attachably and detachably to and from the husking roll 1a. The widths of the husking surfaces of the husking rolls 1a, 1b are formed to approximately the same width as the width of the winnowing path 13. As a result, the paddy in the paddy hopper 6 is sent to the entire surface of the husking surfaces of the husking rolls 1a, 1b and the husked rice is dropped to the entire part of the width of the winnowing path 13, by which the uniform sepn. is assured. The vibration at the time of rotation is suppressed by supporting the husking roll shafts 1a, 1b from both sides of the operation side and transmission side of the machine body.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hulling roll for a huller.

[0002]

2. Description of the Related Art Conventionally, the width of the hulling surface of a hulling roll is only about half of the width of Karamin, and in order to obtain a uniform wind sifting effect over the entire width of the air sifting path, a hulling roll is used. A diffusion plate was provided below the rice paddle, and after the rice was slid out, the squeezed rice was applied to the diffusion plate to diffuse the rice over the width of the wind path. The hulling roll shaft was supported only on the transmission side of the fuselage.

[0003]

In the method of using the diffusing plate to spread the laid rice, the rice is not actually evenly distributed in many cases, and there is a variation in sorting, so that uniform sorting cannot be performed. However, Karin's wind selection effect could not be maximized. In addition, since the conventional hulling roll shaft is supported only on the transmission side of the machine body, it tends to vibrate when the roll rotates, and when sliding the hulling, compared to the gap between the transmission side rolls. Since the gap between the rolls on the operation side is widened, there is a disadvantage in that the escape rate varies.

[0004]

The width of the hulling surfaces of the hulling rolls 1a and 1b is made substantially the same as the width of the wind selection path 13 located below, and the hulling rolls 13a and 1b are extended over the entire width of the wind selection path 13. The rice roll can be spread, and the hulling roll shafts 2a and 2b are supported from both sides of the operation side and the transmission side of the fuselage, and the hulling rolls 1a and 1b are stably supported. -Type huller.

[0005]

[Effect of the Invention] The rice rolled out from the hulling roll falls evenly over the entire width of the wind selection path, so that there is no variation in the selection and uniform selection can be performed. The effect can be maximized. In addition, since the hulling roll shaft is supported from both sides of the operation side and the transmission side of the machine body, it is difficult to vibrate during rotation of the roll, and the gap between the transmission side and the operation side roll does not change. The variation is less likely to occur.

The path 13 is further suctioned, dropped and sorted into a new receiving trough 12, and the rice husks are discharged out of the dust discharge tube 10. The polished rice after the wind selection falls into the raked rice receiving gutter 11, is fried as mixed rice by the mixed rice frying machine 4, and is conveyed to the mixed rice sorting section C.

[0008] The mixed rice sorting section C includes a swing sorting plate 14, a distribution gutter 15, a distribution case 16, a swing arm 17, and a swing device 1.
8, the partition plate 19, 20 and the like. The mixed rice transported by the mixed rice fryer 4 is distributed to a distribution gutter 15 and a distribution case 16.
Is supplied to the swinging sorting plate 14 via the
Due to the relationship between the specific gravity, the coefficient of friction, etc., brown rice with a large specific gravity is unevenly distributed in the horizontal direction, which is the sorting direction, and paddy with a small specific gravity, compared with brown rice, The non-separated mixed rice of unpolished rice and brown rice is distributed in the middle in the middle. The brown rice partition plate 20 and the paddy rice partition plate 19 are arranged on the discharge side of the swinging sorting plate 14, and the brown rice that has drifted distribution on the swinging side is separated by the brown rice partition plate 20 and taken out.
