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 new configuration, and in particular, increases the deweighing rate, and also performs wind selection of immature grains in the wind selection room.
Moreover, the entire structure is made to be robust and inexpensive.

To explain with a diagram, (1) is the supply hopper, (2) is the feeding roll, and the feeding roll (2) is the hopper i.
Of the inclined plates +31 to +41 forming l+, the shaft is fixed inside the tip (5) of the inclined plate (3) provided on the inner side, so that it is extended toward the outer inclined plate (4). The lower end (6) of the outer inclined plate (4) is formed slightly longer, and the rubber roll (7) on the side of the hulling part (9) of rubber roll +71 +81 is pivoted diagonally upward, and the lower end (6) is pivoted diagonally upward. The rubber roll (8) is pivoted diagonally downward. A line A connecting the axis αQ of the rubber roll (7) and the axis U of the rubber roll (8) and the extension line of the lower end (6) of the inclined plate (4) form a T-shape.

Among the pair of rubber rolls +71 +81, the axis αl of the upper rubber roll (7) is a fixed rotating shaft, and the rubber roll (7) can only rotate freely, but the lower rubber roll (8
) is also freely movable, and is freely movable in the direction of arrow W. Also, move the rubber roll (7;
8) Rotate faster than. The unhulled rice 02 flowing through the outer inclined plate (4) and flowing out from its lower end (6) is formed so as to be transferred from the lower end (6) to the upper surface Q3 of the lower rubber roll (8).

The rubber rolls +71 to +81 are provided in the hulling chamber α4. The hulling chamber 1141 is formed between two vertical iron plates αG. Iron plate 090G is rubber roll +71
They are mounted facing each other at a distance that can accommodate +81. Next to the hulling chamber I, a vertical iron plate αa is provided at the same interval as the hulling chamber α4 so as to form a bearing chamber 171. The bearing □□□ of the shaft a9 of the feed roll (2) is attached to the upper position of the steel plate all (+8).The shaft a9 serves both as the shaft of the feed roll 12) and the support shaft of the movable rubber roll (8). . The shaft a9 in the bearing chamber an
A bearing (support) is mounted on the outer periphery of the shaft. An arm &D is attached to the lower end of the bearing (a), a bearing is mounted on the lower end of the arm Qυ, and the shaft an of the moving roll (8) is inserted through the bearing a. A protruding piece is attached to the lower end of the bearing (2), and the adjustment rod c141 is inserted into this. The rod (C) is horizontal;
Moreover, it is a direction perpendicular to the axis 0υ. The shaft has a threaded portion □□□ formed at one end thereof, and is screwed into a threaded cylinder (5) attached to the side wall of the threaded portion. The upper part is the adjustment knob.

The adjustment rod ■ fits loosely into the protrusion (to), and the tip of it fits into the protrusion (to).
An enlarged portion (2) is formed in the protruding portion by protruding from (c), and a coil spring (to) is wound between the protruding piece (c) and the threaded tube @.

c31) is a supply hopper, and (to) is an opening/closing shutter. A wind selection room (to) is formed between the iron plate a5 and aSO that form the hulling room aid.0 The wind selection room (to) is configured so that immature grains can also be passed through the wind, unlike conventional ones. . The bottom of the hulling room I is formed into an upside-down funnel, and the lower end opening opens into the wind channel. ) is installed. G71 is the shaft, and the bearing (to) of shaft 3D is attached to the iron plate aS and G♂.
J is kicked. When in the louse selection room, the air outlet of the windmill (g) is o! It is formed obliquely upward from i, and curves downward at its upper end f4G to meet its formation center. To form the upper end no.
A substantially concentric curved wall U is installed inside, and the curved wall 0Il
A suction port '42 is opened inside. The suction port 112 is formed in the iron plate Oe. Also, the above-mentioned windmill (to) is on the iron plate 00.
The suction port 03 of is opened. The suction port 115 and the suction port are connected through a connection passage 1441. Therefore, the wind in the windmill circulates. The passage 144) is a bearing chamber an
formed within. On the lower side between the air outlet (toward) and the upper end klO, there is a paddy/brown rice fall port ta, which is closer to the air outlet (toward).
is formed, and then an immature grain falling port fa9 is formed. At the bottom of the upper end 0[l, a rice husk drop hole i11 is formed. A motor ha is provided in the bearing chamber (if necessary, the hulling chamber 04 and 1). However, the pulley ω on the axis a9 in 2) and the moving rubber roll + the pulley 511 on the axis all in 8). The pulley mallets of the shaft Q of the fixed rubber roll (Pulley 52 of I, shaft of the windmill (to) +37) are both attached to the outer periphery of the steel plate A mallet on the same plane, and one V belt (goods) is attached to the I will be forgotten. The number of the V-belts (b) may be plural if necessary. (to) is a safety cover. Note that the pulley 6υ> is formed on the pulley 63.

Next, we will discuss the effect.

Since the present invention has the above-described configuration, when the unhulled rice is supplied to the supply hopper 01) and the opening/closing shutter (to) is opened, the unhulled rice α2
is fed out by the feeding roll (2), flows on the inclined plate (4), and flows from its lower end f61 to the upper surface 0 of the moving roll (8).
3 and is supplied to the hulling section (9) without being disturbed by the slowly rotating moving roll (8).

In the hulling section (9), the rice is strongly rubbed and hulled by a fast-rotating fixed roll (7), and a mixture of unhulled rice, unhulled brown rice, and rice husks is collected in a funnel (2), and the bottom opening ( To)
It flows into the wind selection room (To). Inside the wind selection room (To),
Because the wind from the windmill is blowing up, the heavy grains fall to the paddy/brown rice fall port (4 to 9), the immature grains advance a little further and fall to the immature grain fall port, and the rice husks fall to the rice husk fall port. Fall to C1.

The sorting air is sucked into the suction port (4) and circulated through the passage circle to the suction port (13). Place them in parallel at intervals.

Since it is formed of three main vertical iron plates (190υU), it can be formed very easily.In addition, a hulling chamber α4 is formed at the upper position on one side of the vertical iron plates u''3, and a wind-selection chamber ( Since it is formed so that the motor can be installed at the upper position on the other side between the iron plates 09αG in 0 seconds, etc. Also, a wind tunnel is installed on the − side of the wind selection chamber (to), and the wind selection chamber is It is formed on the inside of the other side of the chamber (to), and the suction port i15 and the windmill (to) are connected by a connecting air channel casting, so the sorting air blown from the windmill (to) circulates and removes dust. The wind sorting room (to) is equipped with a paddy/brown rice drop port (4!9), an immature grain drop port 0Q, and a rice husk drop port i1n to prevent it from scattering to the outside. Almost no supply is provided, which improves the sorting of unhulled brown rice.In addition, the axis a9 of the feeding roll (2) and the rubber roll +
