Description

[Detailed description of the invention] This invention was designed to make it possible to hygienically and efficiently attach and detach the paddy hull storage bag that is connected to the paddy hull discharge port of the huller and used when recovering the paddy hulls. This invention relates to an improved paddy hull recovery cylinder connected to the paddy hull discharge port of a rice huller.

Conventionally, to collect paddy hulls discharged from the hull discharge port of a huller, a separate mounting pipe is connected to the hull discharge port, and a paddy hull storage bag is attached to the end of the pipe. This has been done by replacing the rice hull storage bag with a different one each time the bag is full. However, with this conventional method, no matter how quickly the paddy husk storage bag is attached and detached, a large amount of the paddy husk continuously discharged during the momentary attachment and detachment scatters around the surrounding area. Not only did it pollute the workers, but it also fell on the workers, making the work extremely unhygienic.

Therefore, the present applicant himself proposed a rice hull recovery system with a damper mechanism using a bifurcated cylindrical body with a special cross-sectional shape, based on several ideas starting from Utility Model Application No. 54-80652 (see Utility Model Application No. 56-233). We succeeded in developing and putting into practical use a cylindrical body. However, although they were generally able to achieve their purpose as devices for efficiently collecting the rice hulls that were being discharged, the manufacturing and
In terms of handling such as transportation and storage management, it was not always possible to be completely satisfied.

This invention has been improved and developed in order to cope with these actual circumstances, and the details of its configuration are as detailed below.

As can be understood from the representative embodiments of this invention shown in the accompanying drawings, a bifurcated cylinder 1 having a V-shaped or approximately V-shaped appearance in plan is replaced by a bifurcated cylinder 1 having a semicircular or D-shaped cylinder space in cross section. When forming the book cylindrical members 2, 2, the flat outer portions 21 corresponding to the straight sides of the respective cylindrical cross sections of the two cylindrical members 2, 2 are arranged to face each other,
The connection side end structure of both flat outer portions 21, 21 is as follows:
A damper mechanism 3 is formed in a bendable or rotatable structure, and a bifurcated branch in the internal space of the cylinder is provided with a damper mechanism 3 that selectively opens and closes either one of the internal spaces of the two cylinder members 2, 2. In addition to combining
This cylinder body for recovering rice hulls is made up of a combination of an expansion fixture 4 for temporarily fixing the bifurcated expansion degree of the cylinder body 1.

As can be seen from the exploded perspective view shown in FIG. 1 or 2 and the horizontal sectional view shown in FIG. a flat outer portion 21 corresponding to the side;
The other curved outer part 22 may be joined together by spot welding or other means at both upper and lower end edges along the longitudinal direction of the flat plate outer part 21. Outer part 2
1 is previously formed into a substantially U-shaped cross section with a folded piece whose upper and lower edges are slightly bent substantially horizontally in the same direction, and a curved outer portion 22 is formed within both folded pieces. While bending the flat thin plate so that its longitudinal ends are in contact with each other, the restoring force of the curved outer portion 22 holds both together to form a cylindrical member 2 having a semicircular or D-shaped cross section. If they are integrated by spot welding or other means, the work process will be more advantageous.

Although not shown in the drawings, other structures may be formed by bending a single flat thin plate, or depending on the material, they may be integrally molded to have a cylindrical cross section from the beginning to create a semicircular or semicircular cross section. D-shaped cylinder member 2
can also be formed.

No matter which structure the two cylindrical members 2, 2 are formed with, the flat plate-like outer parts 21, 21 of the respective cylindrical members 2, 2 are arranged to face each other. For example, as shown in FIGS. 1 to 3, the structure is such that when the two longitudinal edges are connected to each other, the structure can be bent or rotated about the connection point after connection. It must be formed into a hinge-like structure via a retaining pin 25, as in the embodiment shown, or an interlocking structure, as in the partial perspective view shown in FIG. 4, or other similar structure. In addition, when this flat outer part 21 is formed of a flexible material, for example, a thin iron plate of about 0.3 mm, in addition to the above-mentioned structure, as shown in FIG. It is also possible to continuously form the flat plate-like outer parts 21, 21 of the members 2, 2 from a common single plate-like band plate, and to utilize the flexibility of the bent portion.

In this way, two cylindrical members 2, 2 are formed, and their flat outer parts 21, 21 are arranged opposite each other, and one end edge thereof is bent or rotatably connected. From the state shown in FIG. 7A, where the cylindrical members 2 and 2 are completely symmetrical and parallel, to the state shown in FIGS. A cylindrical body 1 is formed that can be freely expanded or closed.

The cylindrical body 1, which is formed to have a freely expandable degree of expansion, is normally used with an appropriate degree of expansion α as shown in FIG. 7 B and C. The diameter of the opening on the mouth side of the cylinder 1 (the connection port to the hull discharge port M of the huller) is regulated. That is, it is only necessary to select the degree of expansion α each time according to the outer diameter dimension of the hull discharge port M of the rice huller, and as a device for temporarily fixing the selected degree of expansion α,
The expansion fixing device 4 may be an O-ring-shaped band as shown in FIGS. 1 to 3, a clamping fitting as shown in FIG. 6, or the like. In addition, when it is planned in advance that the use of a specified rice hulling machine is limited to those whose outer diameter dimension of the hull discharge port M is approximately constant, the expansion degree α is automatically adjusted accordingly. The claw pieces 24, 24, which are determined by It is also possible to easily determine the predetermined degree of expansion α by bringing the two parts into contact with each other.

On the other hand, the damper mechanism 3 for selecting one of the internal spaces of the two cylindrical members 2, 2 includes a shaft rod 31 having a handle portion and a closing plate 32 integrally attached to the coaxial rod 31. , further formed by the collar parts 33, 33, and each bearing part 23, 2 of the cylinder member 2, 2 before temporarily fixing the degree of expansion α of the cylinder 1.
It will be combined into 3.

The paddy shell collecting cylinder of this invention having the above-mentioned configuration can be in the state shown in Fig. 7A, or
Separate each cylindrical member 2, 2 at the joint of its flat plate-like outer parts 21, 21 and separate it into other parts,
That is, the damper mechanism 3, the expansion fixture 4, the support stand 5, etc. are packed and shipped in a compact combination, and each cylindrical member 2, 2 is separated independently at the stage of use by the purchaser, i.e., a general farmer, etc. In this case, they are first joined together and the damper mechanism 3 is combined, and then the degree of expansion α of the cylinder body 1 is determined according to the outer diameter of the hull discharge port of the rice huller owned by the purchaser, and the expansion is temporarily expanded. Fix it with the opening fixture 4, and
It is fixed at a predetermined height using an assembly type support stand 5 as shown in the figure. After that, the opening on the first side of the cylinder 1 is connected to the hull discharge port M of the huller, and the hull storage bags S and S are connected to the openings on the second side, respectively. When activated, paddy hulls are continuously discharged from the opening on the side not regulated by the damper mechanism 3, and before the paddy hull storage bag S at the same location becomes full, the damper mechanism of the cylinder body 1 is activated. By performing a switching operation using the handle portion of the handle mechanism 3, the discharge of paddy hulls can be switched to the other side without any interruption. Thereafter, as long as the full paddy hull storage bag S is replaced with an empty bag S, the paddy hulls can be collected easily, hygienically, and continuously in the same process.

When all the paddy shell collection work is completed, it is disassembled in the exact opposite manner to the assembly process, and stored in a packing box.

As mentioned above, according to the rice hull recovery cylinder of this invention, since the degree of expansion of the bifurcated cylinder can be made flexible, one type of cylinder can be used in all types of rice hulling machines. becomes possible. The manufacturing process can be greatly simplified. The size of the packaging is much more compact than when it is packaged in a V-shape or approximately V-shape, so it is extremely advantageous for inventory management, transportation, product handling, storage management, etc. Become. Due to the above advantages, the product price is very low. Etc., it is possible to realize a barrel for recovering paddy husk that has a number of functions and effects that could not be expected with conventional products of this type.
