Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a bean threshing machine.

[Conventional technology]

Conventionally, the means for threshing grains such as soybeans is similar to the means for threshing rice, in which the culm is transported along the axis of the threshing drum, and the threshing is adjusted using a large number of threshing teeth provided on the threshing drum. However, this method of threshing using a seeder barrel required post-processing, such as shredding the remaining culm by another means after threshing.

In addition, as in Utility Model Publication No. 35-9457, instead of using a plow barrel, ratchet tooth-shaped plow wheels are attached to two parallel shafts facing each other, and the upper plow tooth ring is connected to the lower plow tooth ring. A peanut threshing machine has been proposed in which the upper part of the peanut is pressed between the two grinder wheels, but it is not only cumbersome to manually operate the upper grinder wheel, but also is suitable for processing peanuts such as soybeans, which have weaker shells than peanuts. For beans of this kind, there are problems such as the grinding action is too severe and the beans are crushed, and this kind of thing cannot be used for threshing beans.

[Purpose of invention]

The present invention was developed in view of the above circumstances, and uses a simple structure and rational means to subdivide whole husks such as beans using a crusher, and separate the culms and legumes using a sorting fan. The branches and bean pods are separated and collected separately, and the branches and bean pods are shredded and threshed using the regular plowing teeth installed in the plowing body, and the bean pods, main culms, branches, etc. are efficiently folded into paper using the long plowing teeth. The purpose is to improve the efficiency of threshing grains such as grains, omit the separate processing of culms, and increase effective operating time and save labor.

[Means for solving problems]

The threshing machine for beans and other grains of the present invention, which solves the problems of the conventional technology, inserts grains such as beans together with the stalks through the supply port of the casing, and threshes them with a milling body equipped with threshing teeth 8 around the periphery. In a threshing machine that separates cut culms and beans using a sorting fan, the surface of the milling barrel has long grinding teeth along the axial direction of the barrel and having a large number of protrusions. 9, and a shredding culm discharge port 10 is provided at a symmetrical position on the opposite side to the supply port of the casing with respect to the above-mentioned milling barrel.
1, and the discharge port 10 is provided with an opening/closing plate 12 which normally has a closing habit and can be opened and closed by means of a spring 11.

[Explanation of Examples]

The details of the embodiment will be described with reference to the drawings. Reference numeral 1 denotes a casing, and an upper part of the inside of the casing 1 has a plow cylinder 2 mounted thereon.

The casing 1 facing one side of the milling barrel 2 is provided with a supply port 3 for miscellaneous grains such as soybeans. A pair of upper and lower feed rolls 4 and 5 are provided for feeding the paper.

The axes of the feed rolls 4 and 5 are aligned with the
The upper roll 4 is made of a flexible and elastic material with a large diameter, and the lower roll 5 is parallel to the axis of the
It has a small diameter and is made of a hard material like metal.

Reference numeral 6 indicates a feed port for miscellaneous grains such as soybeans, 7 indicates a feeding guide plate, and the lower roll 5 is pivoted on the casing 1 so as to project slightly upward from the surface of the guide plate. The inner end of the plow cylinder 7 and the plow cylinder 2 are relatively close to each other.

A large number of teeth 8 having surfaces parallel to the rotational direction of the plow cylinder 2 are provided in a staggered manner over the entire surface of the plow cylinder 2, and in the axial direction of the surface of the plow cylinder 2, the Separately from the serrated teeth 8, long serrated teeth 9 having a large number of protrusion groups are provided.
At least two or more teeth are provided, and the distance between the tips of these teeth 8 and 9 and the inner corner of the guide plate 7 is approximately 2 to 3 crn.
It is set to about.

Reference numeral 10 denotes a discharge port for the shredding culm group, which is provided at a symmetrical position on the opposite side of the supply port 3 to the milling barrel 2;
0 is an opening/closing plate 12 that normally has a closing habit due to the spring 11.
It is opened and closed by

Reference numeral 13 denotes a sorting net provided on the lower side of the wood-burning barrel 2, 14 a sorting fan, and 15 an inclined chute provided between the sorting fan 14 and the sorting net 13. It faces the recovery section 16 provided at the top.

17 is a sorting body having a vertical wire structure, and 18 is a dust discharge port.

In this embodiment, the elongated plow teeth 9 along the axial direction of the plow cylinder 2 are provided at two equal locations, so when cutting the culm into regular pieces, for example, the rotation circumference of the plow cylinder 2 can be By making the feeding speed by the feeding rolls 4 and 5 twice the speed, the main part of the culm is This allows the paper to be folded into approximately 2 to 3 centimeters.

For example, when providing the long pruning teeth 9 at three equal locations,
The same shredding effect as described above can be obtained by setting the feed speed of the feed rolls 4 and 5 to three times the circumferential speed of the plow cylinder.

[Explanation of action]

Next, to explain the operation, when a certain shell culm is pushed between the feed rolls 4 and 5 on the supply stand 6 provided at the supply port 3, the shell culm is automatically moved in the direction of the plow cylinder 2 by both the feed rolls 4 and 5. sent to.

As described above, the upper part of the culm that has been fed is folded by the action of the inner corner of the guide plate 7 and the elongated shear teeth 9, and the branches and the bean pods attached thereto are folded into paper by the action of the inner end corners of the guide plate 7 and the long shear teeth 9. The grains are threshed by Group 8, and the branches and bean pods become fine powder together with the main process.

The beans that have been crushed and threshed fall from the sorting net 13 and are collected in the collection section 16 via the chute 15.The crushed culms that have passed through the sorting net 13 together with the beans are collected from the sorting fan 14 on the way down. The dust is blown away by the wind force in the direction of the arrow, and is discharged and collected from the dust discharge port 18 to the outside.

On the other hand, the shredded culm group located between the milling trunk 2 and the sorting net 13 is
The centrifugal conveying force and wind force provided by the plow cylinder 2 send the waste toward the discharge port 10, and the opening/closing plate 12 is opened to cause the waste to be discharged to the outside.

Then, by the wind force of the sorting fan 14 acting during the fall, the beans are discharged to the outside from the dust discharge port 18, and the beans mixed therein are not affected by the wind force and fall vertically into the waist sorter. 17 and is collected by the collection section 16.

〔effect〕

As described above, according to the present invention, the following effects can be obtained.

(a) The culms of beans, i.e., bean pods, main grains, branches, etc., are all sent to the milling body for threshing, and the legumes are collected in the collection section through a sorting mechanism, where they are collected from other culms and other culms. Of course, cut pieces are discharged and collected separately from pulses by the action of a sorting fan. Since two types of saw teeth are provided, the saw teeth 9 have a group of protrusions, the shedding action is performed by the saw teeth 8, and the shredding of bean pods, processes, branches, etc. is performed by the saw teeth 9, which is superior to the conventional technology. Comparatively, it is possible to improve the processing efficiency of sloughing and culm removal.

(C) The shredded culm group located between the plow cylinder and the sorting net is sent toward the outlet 10 by the centrifugal conveyance force generated by the rotation of the plow cylinder and the wind force generated by the plow teeth 9, and is sent toward the outlet 10 by the opening/closing plate 12. The culms are opened outward against the springs and released to the outside, and when the release is finished, the opening/closing plate 12 closes the discharge port 10 again due to the action of the springs, and this process is repeated to efficiently process the discharge of culms and pulses. sorting and recovery can be efficiently performed in different directions and simultaneously.
