In the configuration in which the orthogonal processing cylinder 2 is arranged above the rear end of the Straw rack 24 of the rocking / sorting apparatus A, and the dust suction fan 3 is arranged on the side of the front portion of the orthogonal processing cylinder 2, below the rocking / sorting apparatus A. The axial center of the dust suction fan 3 is arranged in front of the second conveyor 6 arranged in the above, and the axial center of the orthogonal processing cylinder 2 is arranged in rear of the second conveyor 6, and the suction port 3a of the dust collecting fan 3 is arranged.
And the rotation outer circumference of the processing tooth 2a of the orthogonal processing cylinder 2 are arranged so as to wrap in a side view, and the end of the Straw rack 24 of the swing selecting device A is arranged below the wrap portion.

(E) Embodiments and Functions The objects and configurations of the present invention are as described above, and the configurations of the embodiments shown in the following attached drawings will be described.

FIG. 1 is a side sectional view of a thresher of the present invention, FIG. 2 is an enlarged sectional view of a rear portion of the swing selecting device A, and FIG. 3 is a plan sectional view of FIG.

 The overall structure will be described with reference to FIG.

A feed chain 4 is arranged outside the threshing device. The feed chain 4 holds a grain culm, and the tip of the grain is brought into contact with the handling teeth of the handling barrel 1 to shed grain. Handle 1
A crimp net 13 is disposed below the
A rocking sorting device A is arranged below 13. The orthogonal processing cylinder 2 is arranged above the rear end of the swing selecting device A, and on the side wall on the left side of the machine body at the position in front of the orthogonal processing cylinder 2.
A dust suction fan 3 is provided, and dust is sucked and discharged through an opening formed in the side wall.

The front end of the swing selecting device A is suspended by the front swing rod 10, and the rear portion is suspended by the rear swing rod 11. By removing the front swing rod 10 and the rear swing rod 11, the swing sorting device A can be entirely pulled out from the rear opening of the thresher at the time of inspection and repair. Of.

A sorting and blowing fan 9 is provided below the swing sorting device A, and the swing sorting device A is operated by the sorting wind from the sorting and blowing fan 9.
The grains falling from the are selected by air and divided into the first conveyor 5 and the second conveyor 6.

The swing sorting device A is a grain pan 19, a grain guide plate 12,
The main chaff sheave 14, the Glen sieve 23, the Straw rack 24, the processing body chaff sheave 15 and the like are erected and supported between the left and right side plates 21, 21.

Then, the whole is suspended by the front swing rod 10 and the rear swing rod 11 and swings.

The rear end of the Straw rack 24 is projected to the vicinity of the process chamber guide plate 25 at the front end of the concave device B. The processing chamber guide plate 25 is arranged almost on the extension line of the inclination of the rocking grain plate 16. Left and right side plates 21, 21 of the swing sorting device A
The pivotal support portions 21a, 21b are provided in the
And the second rocking plate 17 is pivotally supported.

In the normal working state, the positions of the first rocking grain plate 16 and the second rocking grain plate 17 are fixed by the bolts 30 and 31 inserted in the pivot holes 21a and 21b and the bolt holes at the upper end. Therefore, the swing sorting device A swings with its position fixed.

The swinging around the portions of the pivots 21a and 21b is performed by removing the front swinging rod 10 and the rear swinging rod 11 and moving the swinging sorting apparatus A as a whole rearward for inspection and repair. It is when pulling out. Since the lower end of the first rocking grain plate 16 and the second rocking grain plate 17 protrudes more than the first grain plate 26 and the second rear grain plate 28, the swing rocking plate is left as it is. This causes interference when pulling out the device A.

Therefore, when the rocking sorting device A is taken out, the bolts that fix the upper parts of the first rocking flow plate 16 and the second rocking flow plate 17 are used.
By removing 30,31 and pulling it out so that it can rotate about the pivotal support portions 21a, 21b, the most swinging grain plate 16
And the second rocking plate 17 is the first plate 26 and the second rear plate.
It is lifted up by 28 and is stored and folded on the side of the swing sorting device A.

On the contrary, even when inserting after inspection and repair, by inserting in the folded state, the first rocking flow plate 16 and the second rocking flow plate 17 are the first rock flow plate 26 and the second rock flow plate. It can be inserted without interfering with the rear grain board 28.

From the bottom surface of the most rocking flow board 16 is hung on the second rear flow board 27, and the most rubber droop 18 is arranged.

Similarly, from the lower part of the second rocking flow plate 17 to the second rear flow plate 28
The second rubber droop 20 is hanging toward the part.

The angle of the main chaff sheave 14 can be adjusted by the operator, and similarly, the angle of the processing body chaff sheave 15 can also be adjusted from the operator's hand.

The concave 8 at the bottom of the orthogonal processing cylinder 2 is a processing chamber guide plate.
It is configured as a concave device B integrated with 25,
The thresher can be inserted and fixed from the rear side.

Then, by removing the concave device B, the rear opening of the thresher is widened so that the rocking / sorting device A can be pulled out.

In the overall structure as described above, in the present invention, the rear stroller 24 of the swing sorting device A, the drive shaft 2b of the orthogonal processing cylinder 2, the drive shaft 3b of the dust suction fan 3, and the second conveyor. 6 of the drive shaft 6b.

Reference numeral 7 is a reduction thrower that returns the second processed material collected by the second conveyor 6 to the handling cylinder 1.

The swing sorting device A extends the Straw rack 24 following the main chaff sheave 14 above the processing chamber guide plate 25, and extends the lower portion below the concave 8 so that the processing drum chaff sheave
It has 15 parts. The rear end of the processing body chaff sheave 15 communicates with the third port to discharge the straw waste that has not fallen to the second conveyor 6.

The main chaff sheave is located above the second conveyor 6.
There are 14 and Strawack 24 parts, and also Glensieve
The end of 23 and the front end of the processing body chaff sheave 15 are arranged.

Therefore, it is the Straw rack that flows into the second conveyor 6.
Grains that have passed through 24, grains with spikes or straw that have not passed through Glensieeve 23, and grains that have passed through treatment barrel chaff sheave 15 from concave 8 flow in.

Regarding the positional relationship, the axial center of the dust suction fan 3 is arranged forward by a distance a with respect to the axial center of the second conveyor 6, and the axial center of the orthogonal processing cylinder 2 is rearward by a distance b in a side view. are doing.

The rear end of the Straw rack 24 faces below the lap portion of the rotation locus of the suction port 3a of the dust suction fan 3 and the processing tooth 2a of the orthogonal processing cylinder 2.

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

First, the dust collecting fan 3 is placed in front of the orthogonal processing cylinder 2 with the orthogonal processing cylinder 2 interposed therebetween.
Is arranged, and the orthogonal processing cylinder 2 is arranged at the rear,
The horizontal distance between the dust collection fan 3, the second conveyor 6 and the orthogonal processing cylinder 2 can be shortened, and the total length of the threshing device can be shortened.

Secondly, the rear end of the Straw rack 24 faces the outer circumference of the rotation locus of the processing tooth 2a and the lap portion of the suction port 3a, thereby moving from the Straw rack 24 to the orthogonal processing cylinder 2.
First, when the treatment tooth 2a is hit, the dust generated by the spiked grains or the grains mixed with straw can be absorbed by the dust suction fan 3, and the dust can be efficiently sucked near the origin of dust generation. .
