Description

[Detailed description of the invention] The present invention relates to a rice hulling device.

The present invention relates to a rice hulling device having a novel configuration, in particular, it is designed to increase the shedding rate, perform wind selection of immature grains in the wind sorting room, and to be able to form the entire hull in a robust and inexpensive manner. It is something.

To explain with a diagram, 1 is a supply hopper, and 2 is a feed roll. It is pivoted inside so that it can be extended toward the outer inclined plate 4. The lower end 6 of the outer inclined plate 4 is formed a little longer so that the lower end 6 faces the hulling part 9 of the rubber rolls 7, 8. Among the rubber rolls 7 and 8, one rubber roll 7 is pivoted diagonally upward, and the other rubber roll 8
is pivoted diagonally downward. Shaft 10 of rubber roll 7
The line A connecting the shaft 11 of the rubber roll 8 and the extension line of the lower end 6 of the inclined plate 4 form a T-shape.

Of the pair of rubber rolls 7 and 8, the shaft 10 of the upper rubber roll 7 is a fixed rotating shaft, and the rubber roll 7 is only free to rotate, but the shaft 11 of the lower rubber roll 8 is free to move. It is movable in the W direction. Further, the rubber roll 7 is rotated faster than the rubber roll 8. The unhulled rice 12 flowing through the outer inclined plate 4 and flowing out from its lower end 6 is
The upper surface 13 of the rubber roll 8 below from its lower end 6
form in such a way that it transfers to

The rubber rolls 7 and 8 are provided in the hulling chamber 14. The hulling room 14 is made up of two vertical iron plates 15,1.
It is formed between 6. The iron plates 15 and 16 are mounted facing each other with a gap that can accommodate the rubber rolls 7 and 8. A vertical iron plate 18 is provided adjacent to the hulling chamber 14 at the same distance as the hulling chamber 14 so as to form a bearing chamber 17 . The shaft 1 of the feed roll 2 is placed above the iron plates 16 and 18.

A bearing 22 is mounted on the lower end of the arm 21, and the shaft 11 of the moving roll 8 is inserted through the bearing 22. A projecting piece 23 is attached to the lower end of the bearing 22,
The adjustment rod 24 is inserted through this. The rod 24 is horizontal and perpendicular to the axis 11.
The rod 24 has a threaded portion 25 formed at one end thereof, and the threaded portion 25 is screwed into a threaded cylinder 27 attached to a side wall 26. 28 is an adjustment knob. The adjustment rod 24 is loosely fitted into the protrusion 23, and its tip protrudes beyond the protrusion 23 to form an enlarged portion 29 in the protrusion, and a coil spring 30 is wound between the protrusion 23 and the threaded cylinder 27. 31 is a supply hopper, and 32 is an opening/closing shutter. A winnowing chamber 33 is formed between the iron plates 15 and 16 forming the hulling chamber 14. Wind selection room 3
3, unlike conventional ones, it is constructed so that immature grains can also be selected by wind. The bottom of the hulling chamber 14 is formed into an inverted funnel 34, and its lower end opening 35 opens into the winnowing chamber 33. A windmill 36 is installed directly below the hulling room 14. 37 is that axis, axis 3
7 bearings 38 are attached to iron plates 15 and 18.
The wind selection chamber 33 is formed obliquely upward from the air outlet 39 of the wind turbine 36, and curved downward at its upper end 40. To form the upper end 40,
A substantially concentric curved wall 41 is attached inside, and a suction port 42 is opened inside the curved wall 41. The suction port 42 is formed in the iron plate 16. Further, the iron plate 16 has an opening 43 for the wind turbine 36 . The suction port 42 and the suction port 44 are connected by a connecting passage 44 . Therefore, the wind from the windmill 36 circulates. The passage 44 is formed within the bearing chamber 17. On the lower side between the blower outlet 39 and the upper end 40, a paddy/brown rice fall port 45 is formed closer to the blower outlet 39, and then an immature grain fall port 46 is formed. A paddy shell dropping opening 47 is formed at the lower part of the upper end 40. The bearing chamber 17
(If necessary, on the hulling room 14 side) there is a motor 48.

Therefore, the drive pulley 48 of the motor 48, the pulley 50 of the shaft 19 of the feed roll 2, the pulley 51 of the shaft 11 of the moving rubber roll 8, the pulley 52 of the shaft 10 of the fixed rubber roll, and the pulley 53 of the shaft 37 of the windmill 36 are all is attached to the outer periphery of the iron plate 18 on the same plane, and a single V-belt 54 is wound around it. A plurality of V-belts 54 may be provided if necessary. 55 is a safety cover. Note that the pulley 51 is larger than the pulley 52.

Next, we will discuss the effect.

Since the present invention has the above-mentioned configuration, when unhulled rice is supplied to the supply hopper 31 and the opening/closing shutter 32 is opened, the unhulled rice 12 is fed out by the feeding roll 2, flows on the inclined plate 4, and passes from the lower end 6 of the unhulled rice to the moving roll. 8 and is supplied to the hulling section 9 without being disturbed by the slowly rotating moving rolls 8. In the hulling section 9, the hull is strongly rubbed by the fast-rotating fixed rolls 7, and a mixture of the unhulled rice, the unhulled brown rice, and the hull is collected in a funnel 34, and the lower end opening 3
5 into the wind selection chamber 33. In the wind sorting room 33, the wind from the windmill 36 is blowing up, so the heavy grains fall into the paddy/brown rice drop port 45, the immature grains advance a little and fall into the immature grain drop port 46, and the paddy husk is turned into paddy. The shell falls into the shell drop opening 47. The sorting air is sucked into the suction port 42, passes through the passage 44, and circulates through the suction port 43.
