Description

[Detailed description of the invention] This invention relates to a rice husk recovery cylinder that is connected to the rice husk discharge port of a rice huller and used to efficiently collect the rice husk discharged from the same discharge port. be.

Recently, the rice husks discharged from the rice hulling machine have been packed into air-permeable or non-air-permeable rice husk storage bags and used as material for underdrain drainage, fuel, compost, and other uses. When collecting the rice husks from the rice huller, connect a plastic bag or a single pipe made of iron plate to the rice husk discharge port of the rice huller, and then connect a connecting pipe with branch pipes directly or with a damper mechanism. The pipes were connected via bifurcated pipes, and rice husks were collected by placing designated rice husk collection bags one by one in each of these branch pipes. However, with this method, it is difficult to exhaust the air discharged from the rice husk discharge port of the rice huller, so that the rice husk cannot be efficiently stored in the rice husk storage bag.

Therefore, in order to deal with these problems, we have carried out intensive research and development, and as a result, we have achieved the following results. In other words, the basic technical idea has already been filed by the applicant of the present invention as Japanese Patent Application No. 55-170103 (see Japanese Unexamined Patent Publication No. 57-94353). As shown in Figure 1, the distribution of rice husks and exhaust air discharged from the rice husk discharge port of the rice huller is as follows in a vertical cross section along the axis of the rice husk discharge port.
The rice husks C pass through in a concentrated manner only in approximately the upper half of the opening cross section of the rice husks discharge port M1, and the lower part is only exhausted air containing some dust. Therefore,
Exhaust air W1 that mainly passes through the upper part containing rice husk C
and the exhaust air W2, which contains almost no rice husk C, are separated and independent, and the exhaust air W2, which contains almost no rice husk C, is discharged as is, and the remaining exhaust air W2, which mainly contains rice husk C, is separated and independent.
If only 1 is guided to the rice husk collection bag P, container, etc., the exhaust air sent to the rice husk collection bag P, container, etc. will be reduced to at least about half of the total exhaust air volume. ,
The influence of the exhaust air is reduced accordingly, and there is no need to prepare a rice husk collection bag P with particularly good ventilation to separate the exhaust air W and the rice husk C, unlike before. The collection becomes extremely simple.

Focusing on the above fact, this invention connects to the rice husk outlet opening and creates an exhaust air W1, which has different properties.
In order to be able to submit W2 separately, supervisor 1
A cylindrical body 2 having a cross-section corresponding to approximately the lower half of the opening cross-section of the rice husk discharge port M1 of the rice huller is formed inside the main pipe 1 and is longer than the standard length of the main pipe 1, and the cylindrical body 2 extending from the main pipe 1 is enclosed therein. Thus, the rice husk discharge pipe 4,4
This is a cylinder for collecting rice husks that is connected and combined with...

The main pipe 1 is usually made of iron plate and has a standard length of about 1 m, but it may be made of synthetic resin if necessary. Furthermore, in addition to those that have already been formed into a circular cross section, as shown in the representative embodiment of this invention shown in the exploded perspective view of FIG. 11,11
If so, it will be advantageous in terms of manufacturing and subsequent handling. In the figure, numerals 12, 12, . . . indicate joint fittings for assembly.

On the other hand, the cylindrical body 2 accommodated and formed within the main pipe 1 is
As shown in the embodiment of FIG. 2, it is made of soft synthetic resin and has a continuous length that is an integral multiple of the standard length of the main pipe 1, usually about 5 to 10 lengths. form into something. A fixing metal fitting 3 having a semicircular cross section is combined with one end of the
One end of the cylindrical body 2 is connected to the main pipe 1 by the fixing fitting 3.
It is designed to be fixed to the lower part of the connection end on the side of the rice husk discharge port M1 of the rice huller.

The fixing fitting 3 is, for example, in the shape of a short semicircular tube, as in the illustrated embodiment, and the lower curved piece 31 is formed in a shape that fits well with the inner circumferential wall of the main pipe 1, and the upper horizontal piece 32 has a folded piece 33 above, ears 34, 34 are formed on both sides of the folded piece 33, and a tongue piece 35 is formed in the direction opposite to the folding direction of the folded piece 33. do.

Like the main pipe 1, the rice husk discharge pipe 4 is made of gutter-like bodies 41, 41 which can form a circular cross section by combining them as shown in FIG. 2, in addition to the pipe body already formed with a circular cross section. It can also be made to consist of One or more branch pipes 42 are provided downward in the middle of this pipe body, and serve as rice husk discharge ports to the rice husk storage bag P, and are located at appropriate locations inside the pipe body on the axis line of the pipe body or on the same side. A plurality of support rods or plates 43, 43, . . . are arranged in a direction horizontally orthogonal to the coaxial line at a slightly higher position. Usually about 5 to 10 rice husk discharge pipes 4 constructed in this manner are prepared and are connected and combined in sequence starting from the main pipe 1.

The rice husk collecting cylinder of this invention, which is composed of the above-mentioned components, is used in the following manner.

First, the cylindrical body 2 is disposed inside the main pipe 1, and one end of the cylindrical body 2 is fixed by the fixing fitting 3 at a position slightly shifted inward from the one end of the main pipe 1. Therefore, the other end of the cylindrical body 2, which is longer than the main pipe 1, protrudes sufficiently from the other end of the main pipe 1. The end of the main pipe 1 on the side where the cylindrical body 2 does not protrude is connected to the rice husk discharge port M1 of the conventional rice huller M. At this time, the cylindrical body 2 of the rice husk discharge port M1 accommodated in the main pipe 1
must be connected so that the end surface pressed and fixed by the fixing fitting 3 accurately encompasses substantially the lower half of the opening cross section of the rice husk discharge port M1.

Next, the rice husk discharge pipes 4, 4... are successively connected to the protruding end of the cylindrical body 2 of the main pipe 1.
The connection is such that the cylindrical body 2 protruding from the main pipe 1 connects to the support rods or plates 43, 43 of the rice husk discharge pipe 4...
It must be inserted into the rice husk discharge pipe 4 in advance so as to be located above the rice husks. Therefore, as is clear from the vertical cross-sectional view (vertical cross-section in the direction along the axis of the main pipe 1 and the rice husk discharge pipe 4) of this device in the usage state shown in FIG.
gradually moves diagonally upward from the end located on the side of the rice husk discharge port M1 of the rice huller M, and the rice husk discharge pipe 4
Approximately the upper half of the interior of the rice husk discharge pipe 4 extends horizontally from a portion supported by the support rods or plates 43, 43, . . . .

On the other hand, the branch pipes 42, 4 of the rice husk discharge pipes 4, 4...
2... are inserted into the open openings of rice husk storage bags P, P... of appropriate properties, such as breathable mesh bags, non-breathable plastic bags, other paper bags, jute bags, etc. The rice husk storage bag P can be supported by preparing an appropriate stand and hanging it, or by directly tying it to the branch pipe 42 of the rice husk discharge pipe 4, or by attaching the support rod or plate 43 of the rice husk discharge pipe 4 to the It is also possible to make the rice husk discharge pipe 4 protrude outwardly on both sides, and to use both sides of the protruding support rod or plate 43 as a hanging support part for the rice husk storage bag P. (The support rod 43 shown in FIG. 2 is based on the embodiment.) When rice husks are collected with the rice husk collecting cylinder of this invention formed in this way, the conventional rice hulling machine M
The rice husk C discharged from the rice husk discharge port M2 is separated relatively clearly in the vertical direction into a discharge wind W ₁ which mainly contains rice husk C and a discharge wind W ₂ which hardly contains rice husk C. Because of this, the cylindrical body 2 inside the main pipe 1, which has one end facing the lower half near the opening,
, only the exhaust air W ₂ containing almost no rice husk C enters, and is independently discharged outside through the main pipe 1 and the rice husk discharge pipes 4, 4. The exhaust air W ₁ is approximately half of the exhaust air discharged from the huller M. The main pipe 1 and the rice husk discharge pipes 4, 4...
Only a very small amount of exhaust air is discharged from the branch pipes 42, 42, . Therefore, the rice husk storage bag P that stores the rice husk C
The properties of the rice husk C do not need to be particularly limited, and the rice husk C can be freely used or utilized as the rice husk storage bag P, such as a bag with properties suitable for the subsequent handling purpose or any bag on hand.
Moreover, each branch pipe 42, 4 of the rice husk discharge pipe 4, 4...
2... Due to the decrease in the amount of exhaust air passing nearby, the previous branch pipe 4, which was closer to the huller M,
2, the rice husks C do not fall easily, and therefore,
To efficiently collect rice husk C even from a location close to the huller M, whereas it would be meaningless to install a branch pipe from a location far away from the huller M, which would have made the efficiency that much worse. There is also the advantage of being able to

In addition, during rice husk collection work, approximately half of the exhaust air is independently guided ahead of the leading edge of the rice husk discharge pipes 4, 4, etc., so dust is spread all over the work area. There is no mess, and the work can be done more hygienically.

Furthermore, since the mechanism is extremely simple,
Not only is it extremely easy to handle, it is also advantageous in terms of product manufacturing, transportation, and sales.

As described above, the rice husk collecting cylinder of this invention is
This mechanism has been created to correctly recognize and rationally utilize the rice husk discharge status of conventional rice hulling machines, and its technical concept is new and its operation and effects are extremely excellent. be able to.
