Description

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

(b) Prior Art Conventionally, a technique has been known in which treatment cylinders are arranged in the front-rear direction and an orthogonal treatment cylinder is placed close to the cough treatment cylinder. For example, it is disclosed in Japanese Utility Model Application Publication No. 54-13880.

(c) Problems to be Solved by the Invention The present invention is an improvement over the conventional technique in which the processed material after being processed by the orthogonal processing cylinder is refluxed onto the drain pan of the oscillating sorting device. It is.

In addition, in another prior art, when a parallel processing cylinder is provided parallel to the processing cylinder, the material to be processed after being processed by the parallel processing cylinder is returned from the processing cylinder chamber to This improves the difficulty of entering the handling room.

Also, in the case of parallel processing cylinders, there is a crimp between them! 1i21 is arranged, the problem that the processing barrel teeth and the processing teeth could not be brought close to each other has been improved, and the processing barrel teeth and the processing teeth can be brought close to each other at the position where the orthogonal processing cylinder approaches the processing cylinder. The structure is such that grains with spikes and grains with stalks can be completely shed.

(d) Means for Solving the Problems The objects of the present invention are as described above.Next, the configuration for achieving the objects will be explained.

Above the front part of the handling barrel 4, which is arranged in the longitudinal direction of the aircraft and rotates,
The orthogonal processing cylinder 3 arranged perpendicularly to the processing cylinder 4 is rotated, and in the portion where the orthogonal processing cylinder 3 approaches the processing cylinder 4, the processing cylinder teeth 1 and the processing teeth 2 are rotated so as to approach each other. It is.

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

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

Therefore, as seen in the plan view of Fig. 1, the direction of the resultant force of the material being sent from the processing barrel chamber C to the handling chamber A is indicated by the arrow m.
The direction of the resultant force of the processed material in the handling cylinder 4, which receives this, is in the direction of arrow n, and since the directions of the yuri forces intersect at approximately right angles, a strong processing force acts on the processed material being input. ,
It is now possible to remove grains with spikes and grains with attached stalks, which were previously difficult to remove.

In addition, since the treated material is returned to the front end position of the handling cylinder 4, the processing process where it is re-treated by the handling cylinder 4 can be extended, and grains with ears and grains with stalks attached can be completely shed.

In addition, as shown in FIGS. 2 and 3, the processing barrel teeth 1 of the orthogonal processing barrel 3 and the handling teeth 2 of the processing barrel 4 are rotating close to each other at the part where the reduction is introduced. All grains with spikes and grains with stalks passing through are subjected to strong processing force,
It was possible to improve the shedding performance.

(f) Embodiment The object, structure, and operation of the present invention are as described above. Next, the structure of the embodiment shown in the attached drawings will be explained.

Fig. 1 is a plan sectional view of the 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 the orthogonal processing cylinder is spirally configured, and Fig. 4 is the same as Fig. 1. 3 is a side sectional view of the embodiment of FIG. 2; FIG.

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

A feed chain 11 is arranged on the left side of the threshing device as shown in FIG. It is inserted into. The handling teeth 2 installed in the handling barrel 4 engage with the tip of the ear inserted into the handling chamber A, thereby threshing the grains.

The grains after being threshed by the handling cylinder 4 fall from the crimp M421 onto the grain pan 16 and chaff sieve 17 of the swing sorting device B.

In addition, straw waste, grains with spikes, and grains with branches attached that do not pass through the crimp m21 are removed from the straw waste outlet 22 at the rear end of the crimp 1i121.
The liquid is ejected and falls onto the stroke rack 18.

The grains that have fallen from the chaff sieve 17 are sieved again by the sorting net 13 and are first fed into the conveyor 8. While falling from the sorting net 13 onto the conveyor 8, the pieces are sorted by the sorting air discharged from the sorting fan 9.

In addition, grains with ears and grains with stalks that do not fall from the chaff sieve 17 reach the top of the straw rack 18, are conveyed by the straw rack 18, and are thrown into the rear orthogonal processing cylinder 6. The grains processed by the rear orthogonal processing cylinder 6 fall from the concave 12 onto the second conveyor 7.

A reduction thrower blade 20 is arranged at a position where the second conveyor 7 comes out of the machine body, and the processed material thrown up by the reduction thrower blade 20 is thrown into the processing barrel chamber C by the reduction thrower cylinder 5. It is.

Inside the processing barrel chamber C, an orthogonal processing barrel 3 having processing barrel teeth 1 implanted therein is disposed.

As shown in FIG. 4, a dust suction port of a dust suction fan 15 is opened at the upper rear part of the rear orthogonal processing cylinder 6, and the dust suction fan 15 is disposed within the fan case 14.

In the embodiments shown in FIGS. 1, 2, and 4, the orthogonal processing cylinder 3 is constructed of the processing cylinder 3 and the processing cylinder teeth 1 implanted therein. Similarly, the processing cylinder may be omitted and a spiral orthogonal processing cylinder lO like a screw conveyor may be used.

In this embodiment as well, the tip of the spiral needs to be placed close to the handling teeth 2 of the handling cylinder 4.

22 is a crimp net forming the lower surface of the processing barrel 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 disposed so as to intersect with each other at the upper front part of the processing cylinder 4, the space of the processing cylinder chamber C in which the orthogonal processing cylinders 3 are arranged and the processing cylinder chamber C in which the processing cylinders 4 are arranged are The space of chamber A can be overlapped at the input section, and a moment occurs when the forced feeding force of the orthogonal processing cylinder 3 and the rearward feeding force of the handling cylinder 4 act directly and simultaneously on the reduced product. The connection from the processing barrel chamber C to the handling chamber A can be successfully performed, and the material to be processed in the processing barrel chamber C can be smoothly fed into the handling chamber A.

Second, since the direction of the resultant force when the material to be processed is inputted by the orthogonal processing cylinder 3 and the direction of the resultant force transferred to the culm by the handling cylinder 4 are substantially perpendicular to each other, it is treated as the processing cylinder tooth 1 for grains with ears and grains with stalks attached. The engagement force of the teeth 2 is increased, and the shedding performance is improved.

Thirdly, the processing cylinder teeth l of the orthogonal processing cylinder 3 and the processing teeth 2 of the processing cylinder 4.
By arranging them close to each other in the input section and rotating them, grains with spikes and grains with attached stalks engage with each other in narrow areas and are shed, thereby improving grain shedding performance.
