Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an orthogonal processing cylinder of a threshing device mounted on a combine or the like.

(B) Conventional Technology It has been conventionally known that the handling cylinder is arranged in the front-rear direction and the orthogonal processing cylinder is arranged at a position close to the handling cylinder. For example, it is as in Japanese Utility Model Publication No. 54-13880.

(C) Problems to be Solved by the Invention The present invention has improved the above-mentioned conventional technique in that the processed material after being processed by the orthogonal processing cylinder is refluxed on the grain pan of the rocking sorter. It is a thing.

Further, when a parallel processing cylinder parallel to the handling cylinder which is another conventional technique is provided, in the portion where the processed material after being processed by the parallel processing cylinder is put back into the handling chamber of the handling cylinder, This is an improvement on the difficulty of entering the handling room.

Further, in the case of the parallel processing cylinder, since the crimp net 21 is arranged between them, the point that the processing cylinder tooth and the handling tooth could not be brought close to each other was improved, and the position where the orthogonal processing cylinder was approached to the handling cylinder was improved. Then, the treated body tooth and the treating tooth are brought close to each other so that the grain with spikes and the grain with branching branches can be completely shed.

(D) Means for Solving the Problems The object of the present invention is as described above, and the configuration for achieving the object will be described below.

A portion where the orthogonal processing cylinder 3 arranged in the direction orthogonal to the handling cylinder 4 is rotated above the front portion of the handling cylinder 4 which is arranged and rotated in the machine longitudinal direction, and the orthogonal processing cylinder 3 approaches the handling cylinder 4. In the above, the processing body tooth 1 and the handling tooth 2 are rotated close to each other.

(E) Action of the Invention Since the present invention is configured as described above, it performs the following actions.

The rotation direction of the orthogonal processing cylinder 3 is as shown by the arrow shown in FIG. 4, and the rotation direction of the handling cylinder 4 is rotated as shown by the arrow in FIG. 2 and FIG.

Therefore, as can be seen from the plan view of FIG. 1, the resultant force direction of the processed product sent from the processing chamber C to the handling chamber A is the direction of arrow m, and the resultant direction of the processed product of the handling barrel 4 receiving this is the arrow direction. Since it is the direction of n, and both resultant force directions intersect at a substantially right angle, a strong processing force acts on the processed material to be thrown in, and it is possible to shed grains with spikes and branches attached to branches that were difficult to shed in the past. It is a thing.

Further, since the processed material is returned to the front end position of the handling cylinder 4, the processing stroke received by the handling cylinder 4 again can be lengthened,
It is possible to completely shed grain with spikes and grains attached to branch shoots.

Further, as shown in FIGS. 2 and 3, the processing body tooth 1 of the orthogonal processing body 3 and the handling tooth 2 of the handling body 4 are rotated in close proximity to each other in the portion where the reduction injection is performed. All the particles with spikes and the particles attached to branch shoots that were passed through were subjected to a strong treatment force, and the shedding habit was able to be improved.

(F) Embodiments The object, structure, and operation of the present invention are as described above. Next, the structure of the embodiment shown in the accompanying drawings will be described.

FIG. 1 is a plan sectional view of a threshing device of the present invention, FIG. 2 is a rear sectional view of the same, FIG. 3 is a rear sectional view of an embodiment in which an orthogonal processing cylinder is spirally configured, and FIG. 4 is FIG. FIG. 3 is a side sectional view of the embodiment of FIG. 2.

Referring to FIG. 4, the overall configuration of the threshing device of the present invention will be described.

A feed chain 11 is arranged on the left side of the threshing device as shown in FIG. 1, and in a state in which the root of the grain culm is sandwiched by the feed chain 11, the handling chamber A is provided with the tip of the handling barrel 4. Is inserted into. The handling teeth 2 planted in the handling barrel 4 are engaged with the tips of the ears inserted into the handling chamber A to shed grain.

Grains that have been shredded by the handling cylinder 4 fall from the crimp net 21 onto the grain pan 16 and the chaff sheave 17 of the swing sorting device B.

In addition, the straw chips, the particles with spikes and the particles attached to the branch sprouts that do not pass through the crimp net 21 are discharged from the straw waste discharge port 22 at the rear end of the crimp net 21 and fall onto the straw rack 18.

The grains dropped from the chaff sheave 17 are again sieve-sorted by the sorting net 13 and put into the first conveyor 8. While being dropped from the sorting net 13 to the first conveyor 8, the wind is picked by the sorting wind discharged from the wind sorting fan 9.

In addition, grains with spikes and branch adhering grains that do not fall from the chaff sheave 17 reach the Straw rack 18 and
It is conveyed by 18 and put into the rear orthogonal processing cylinder 6. The grain processed by the rear orthogonal processing cylinder 6 drops from the concave 12 to the second conveyor 7.

A reduction thrower blade 20 is arranged at a position where the second conveyer 7 goes out of the machine body, and the processing object bounced up by the reduction thrower blade 20 is processed by the reduction thrower cylinder 5 into a processing chamber C.
Will be thrown into.

The orthogonal processing cylinder 3 in which the processing cylinder teeth 1 are planted is arranged inside the processing cylinder chamber C.

As shown in FIG. 4, a dust suction port of the dust suction fan 15 is opened above and rearward of the rear orthogonal processing cylinder 6, and the dust suction fan 15 is arranged in the fan case 14.

The embodiment shown in FIGS. 1, 2, and 4 shows an embodiment in which the orthogonal processing cylinder 3 is composed of the processing cylinder 3 and the processing cylinder teeth 1 planted therein. As described above, the processing cylinder may be eliminated and the spiral orthogonal processing cylinder 10 like a screw conveyor may be used.

Also in the case of this embodiment, the tip of the spiral needs to be arranged close to the handle teeth 2 of the handle cylinder 4.

 Reference numeral 22 is a crimp net forming the lower surface of the processing chamber C.

(G) Effects of the Invention Since the present invention is configured as described above, it has the following effects.

First, since the orthogonal processing cylinders 3 are provided in the upper front part of the processing cylinder 4 so as to intersect with each other, the space of the processing cylinder chamber C in which the orthogonal processing cylinders 3 are arranged and the processing cylinders in which the processing cylinders 4 are arranged are arranged. Since the space of the chamber A can be overlapped at the charging portion, a moment occurs in which the forced feeding force of the orthogonal processing cylinder 3 and the backward feeding force of the handling cylinder 4 directly act on the reduction processing object at the same time. The transfer from the processing chamber C to the handling chamber A can be performed well, and the processed material in the processing chamber C can be smoothly sent into the handling chamber A.

Secondly, since the resultant force direction at the time of introducing the treated material by the orthogonal treating cylinder 3 and the resultant force direction for transferring the grain culms by the handling drum 4 intersect substantially at right angles, the treated body tooth 1 and the treated body tooth 1 for the spiked grains and the branches adhering grains are treated. The engaging force of the tooth 2 is increased, and the shedding property is improved.

Thirdly, the treating body tooth 1 of the orthogonal treating body 3 and the treating tooth 2 of the treating body 4 are arranged close to each other at the feeding portion, and both are rotated, so that a portion having a spiked grain or a branching stem adhering grain is narrow. Since the particles are engaged and the particles are shredded, it is possible to improve the shredding property.
