Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial application field The present invention provides an upper and lower rod removal cone having a weighing surface and vertically opposing each other around a rotatably vertically installed weighing shaft. A deweighing section removes the rice husks using both of the deweighing cones, a wind-selection section separates the scraps from this de-weighing section into brown rice and rice husks, and removes the rice husks, This invention relates to a rice hulling machine that is integrated with a rice milling section that mills brown rice.

(b) Conventional technology Conventionally, in a hulling rice milling machine that integrally comprises a weighing section, a winnowing section, and a rice milling section to obtain brown rice from paddy, these sections are arranged in relation to each other. There is no technical structure that has a strong composition and allows for the easy attachment and detachment of any of its parts.

Therefore, it is not easy to clean each part at the end of the rice hulling and rice milling work, and the reality is that this is a difficult task.

(B) Problems to be Solved by the Invention Therefore, the present invention solves the problem in that the conventional hulling rice milling machine has a structure in which each of the parts of the conventional rice hulling machine, such as the deweighing part, the winnowing part, and the rice polishing part, are strongly integrated with each other. In view of the composition of the scale, it is difficult to clean it, so the aim is to make this easier.In particular, the wind separation section that receives the debris from the weighing section, which generates a large amount of dust, is designed to make cleaning easier. However, since small-sized rice milling machines have a narrow flow path for grains, which makes cleaning extremely difficult, we aimed to eliminate this difficulty. It is provided as a purpose.

B) Means for Solving the Problems The present invention attempts to take the following measures in order to achieve the above object.

That is, an upper debinding cone and a lower decontamination cone, each having a complete decontamination surface, are disposed vertically opposite to each other on the periphery of a decontamination shaft that can be freely rotatably installed vertically. A paddy product comprising an integral structure of a wind-selecting section below the wind-selecting section that sorts out the debris from the wind-selecting section and removing the rice husks, and a rice milling section that mills the brown rice from the wind-selecting section. In the rice milling machine, the entire wind-selection group that constitutes the wind-selection process, which is an intermediate process among the dehulling, wind-selection, and rice-polishing processes of the rice-hulling machine, is configured to be removable.

(E) Function Since the present invention is configured as described above, when the wind selection section is installed below the dehulling section, it is possible to sort out the debris from the dehulling section and remove the rice husks. The brown rice from which the rice husks have been removed is supplied to the rice milling department to obtain white rice, and when cleaning is required at the end of the work, the entire wind-selection group can be easily removed, and not only the wind-selection department but also the removal of rice can be done. The parts can be easily cleaned from below.

(f) Example The present invention will be described in detail below with reference to embodiment figures.

The rice hulling machine shown in this section is a small one, and the dehulling section (A)
It is integrally constructed within a machine body (1) which is constructed by incorporating a wind sorting section, a rice milling section (C), and 95 electric motors.

That is, as shown in Fig. 4, the removing rod part (A) has a removing rod shaft (3) installed vertically in a vertical tube (A) that is rotatably installed, and the upper side of the removing rod shaft (3). A grain feeding chamber (5) is formed by wrapping a screw blade (4) around it and a vertical cylinder (A), and the lower side is formed into a prismatic column (3a). Also, the vertical tube (
As shown in FIGS. 5 and 6, guide grooves (6) inclined in the lateral direction are formed on the outer periphery of the lower side of A), and are equally spaced around the circumference υ.

(7) is a holding member that is rotatably fitted onto the lower side of this vertical tube (A), and the guiding bolt (8) is passed through this holding member (7).
) are screwed into the guide bolts (8), and the tips of the guide bolts (8) are located within the guide grooves (6), respectively, and the holding member (7) is held around the outer circumference of the vertical cylinder (A). When the guide bolts (8) are turned in the forward or reverse direction, each guide groove (6)...
The holding member (7) is configured to move up and down while rotating while being guided by the holding member (7).

(9) is the upper demixing cone, α0) is the lower demixing cone,
The upper demixing cone (9) and the lower demixing cone (10) have a concave and a convex taper part α force and (A), respectively, and the taper part (11) and ((A) Rubber materials are welded to the opposite surfaces of the demixing rods to form removal rod surfaces 03) and (4), respectively. A square hole is bored in the boss portion (1oa), and the rod is fitted into the square column (3a) of the above-mentioned rod removal shaft (3) so as to be able to slide vertically only.

Therefore, the upper demixing cone (9) and the lower demixing cone (
10) has a desexing surface 03) and 0→ around the desexing rod shaft (8), the upper demixing cone (9) is vertically displaced within a certain range, and the lower mixing cone (10) is the desexing surface 03) and 0→. It rotates together with the shaft (3) and is configured to be movable up and down at the prismatic portion (3a).

Next, the removal pressure adjustment mechanism of this removal rod part (8) will be explained.

(+5) is a vertical receiving cylinder body, and a vertical axis α6) is rotatably attached to the bottom of this receiving cylinder body μs) in a state concentric with the above-mentioned rod removal shaft (8). is installed with the lower part of the adjustment shaft (7) screwed onto the adjustment shaft, and the adjustment shaft (adjustment body a8 with a screw threaded on the circumferential surface of the adjustment shaft (1η)) is screwed into the adjustment shaft (1η).
A compression spring (19) is interposed between the boss part (1oa) of the lower demixing cone αO) and the demixing surface 0→ of the lower demixing cone (10). (
9) is in pressure contact with the desexualizing surface (13). (A) is a horizontal shaft that is rotated by a handle (A1), and a bevel gear a) H that meshes with each other is fitted into this horizontal shaft (A1) and the vertical axis α6).

By this, when rotating hand) v (A11, the horizontal axis (
8)), bevel gear H) (A2), vertical axis α6) and adjustment shaft (17), the adjusting body α8) moves up and down to adjust the elastic force of the compression spring (19) to be strong or weak, thereby adjusting the lower demixing cone. The deweighing pressure is adjusted by changing the pressing force of the upper demixing cone (9) of the deweighing surface α→ of α0) on the deweighing surface (19).

The other components of this demixing pressure adjustment mechanism Ω except the nodle (A1), the upper demixing cone (9) and the lower demixing cone αO) are funnel-shaped as shown in FIG. 1 when viewed from the front side. The receiver (A3) is built in a receiver (transfer) with a narrow lower part, and the receiver (A3) is removably supported on the front and rear sides by bolts (B) and, for example, the fuselage (1). The above-mentioned holding member (
γ) is minimized.

The wind selection section (B) is located below the scale section (A) and has a wind selection chamber 128 formed in communication with the lower part of the receiver (transfer).

) is open.

Figure 1 shows a suction fan attached to a vertical intermediate shaft (83), and this suction fan chamber and the exhaust port Gl) are connected to each other for suction/<if.

When connected, both ends of the suction nozzle (Eve Co., Ltd.) can be connected and disconnected to the exhaust port 3IJ and the suction side of the suction fan side chamber, for example, by tightening (not shown).

The rice milling section (C) is a vertical friction type equipped with a rotatable vertical milling trochanter, and is located adjacent to the de-aging section (A) and the wind sorting section (B). A rice selection section ◎ and a rice polishing machine (a grain lifting cylinder with a screw conveyor installed between it and 0) are installed upright, and they are arranged as shown in the layout diagram of FIG.

In addition, (■) and (initially, the above-mentioned grain barrel μ is used in the paddy tank and brown rice tank.
A discharge port (38) opened at the upper part of the brown rice tank (38) is opened above the brown rice tank (35), and the lower end of the grain selection chamber (35) is connected in communication with the lower end of the grain selection chamber (35).

Therefore, the wind selection part ◎ forming the wind selection chamber μs) communicates the upper part of the wind selection chamber μs) with the lower part of the receiver mark), and the The lower part is also connected by pressing the front and rear fixing tools (for the front and rear fixing tools) and from the side by tapping).
) is connected to the lower end by pressure contact.

Therefore, for example, as shown by the imaginary line in FIG. 1, when the holding member (γ) is rotated and displaced upward by the operating rod (6) and the linkage connected thereto, the upper weighing cone ( The demolding surface α3) of 9) is the lower demixing cone (10
) separates from the debonding surface α even though it is compressed by the compression spring (19), and if it is displaced downward, it comes into pressure contact with the debonding surface 0→.

When putting paddy into the paddy tank (depth) and supplying the paddy into the grain feeding chamber (5) for hulling, press the dehulling surface 03) and α→ as described above so that both dehulling surfaces can be used. (IB) and C14) are pressed against each other through the rice grains and are removed by the rubbing action, and the scraped material is guided downward by the receiver (-) and the rice husks are removed by wind selection in the wind selection chamber (A8). The brown rice is lifted up with a grain lifting cylinder (35) and put into a brown rice tank (35), and then milled in the rice milling section (q) to become white rice.

When cleaning at the end of work, remove the entire windscreen ◎. In other words, the example of the suction pipe is the exhaust port C3.
1), and release the connection between the lower end of the lower end of the grain tube (8)) and the lower end of the upper end of the grain barrel. When the connection with the wind selector (B) is released, the wind selection section (B) can be taken out to the front side of the fuselage (1). (See Fig. 8) Also, from the state shown in Fig. 8, remove the lid (A6), loosen the bolts supporting the receiver (μs), and lower the receiver μs). When pulled down, the built-in demixing pressure adjustment mechanism (0 boar common machine body (1)) can be taken out.

In this case, the boss portion (1oa) of the lower demixing cone α0) can be removed downward from the prism (3a) portion of the demixing shaft (3), and the lower demixing cone αO) can also be taken out. (See Fig. 9, 5) Then, not only the lower demixing cone α0) but also the upper demixing cone (9) fitted and fixed to the υ holding member (A) can be replaced.

(B) Effects of the Invention As detailed above, the present invention has an upper demixing cone and a lower demixing cone, each having a debonding surface, which are arranged vertically opposite to each other around a debonding shaft that is vertically installed so as to be rotatable. A dehulling section that agitates the rice using both dehulling cones, a wind-selection section below the de-hulling section that sorts out the residue from the dehulling section and removes the rice husks, and a wind-selection section that removes the rice husks from the wind-selection section. In a hulling rice milling machine that is integrally configured with a rice milling section that performs hulling, the entire wind sorting section is configured to be detachable, so that the demixing process and the rice milling process can be carried out at the end of the hulling rice milling operation, etc. This system constitutes the wind selection process, which is an intermediate process in the above process, and is located below the agitation part and generates a large amount of dust.This system easily and easily accepts the debris from the agitation part, which generates a large amount of dust, and performs the wind selection process. Since it can be removed, it is easy to clean not only the wind screening section but also the agitation section from below, and the workability of disassembling and assembling the surrounding components can be improved.

In particular, small-sized rice milling machines had a narrow flow path for grain, which made cleaning extremely difficult, but this problem could be overcome.
