Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a straw discharge device after threshing in a direct current combine for threshing by throwing the whole cut grain culm into a handling barrel rotor. .

(B) Conventional technology Conventionally, in an automatic threshing machine that threshes only the tip part with a culm sandwiched by a feed chain, a technology in which a processing cylinder is placed behind an eccentric position in parallel with the handling cylinder is It is known.

For example, JP-A-60-256315 and JP-A-61-1289.
No. 41 gazette, Jpn.Sho 57-6111 gazette, and Jpn.
This is as disclosed in JP-A No. 4 and JP-A No. 61-177922.

However, in the DC type combine, there was no technique for disposing the processing cylinder behind the eccentric position while being parallel to the handling cylinder.

(C) Problems to be Solved by the Invention In the conventional DC combine harvester, all the grain culms cut by the reaping unit are put into the handling barrel rotor 1 around which the spiral 1a is wound, and the rear side in the traveling direction of the machine body. The spiral rotation was performed in the direction to thresh, and the straw was discharged directly from the rear end of the handling barrel rotor 1 to the field scene.

For this reason, the straw outlet of the handling barrel rotor 1 is arranged above the swing sorting device 4, and when the straw outlet is to be opened rearward of the handling barrel rotor 1, the swing sorting device 4 moves. There is a problem that the handling cylinder rotor 1 inevitably becomes long, because it must be arranged further rearward than the end.

Further, when the number of straws increases, the dust outlet provided at the rear end of the swing sorting device 4 is blocked, and the blowing passage of the sorting air from the sorting fan 7 is blocked, which also causes the deterioration of sorting performance. It was.

Further, in the conventional configuration, since the dust discharged from the swing sorting device 4 and the straw discharged from the handling body rotor 1 both fall to the same position, the waste is concentrated on one side of the cut, In the next step, the right divider hooks the straw and inserts it into the handling barrel rotor 1 again, resulting in a decrease in workability.

 The present invention improves on this point.

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

In a direct current combiner in which the whole cut grain culm is put into the handling barrel rotor 1 to thresh, the handling barrel rotor 1 is arranged parallel to the traveling direction, and it is biased to the already trimmed side at the rear part of the handling barrel rotor 1. In consideration, the straw rotor 2 which is also oriented in the traveling direction is arranged, the spiral 1a is wound around the front part of the handling barrel rotor 1, and the straw is discharged around the end of the handling barrel rotor 1. Sprawling teeth 1c for guiding spouting are planted on the side of the straw rotor 2, and scraping teeth 2b for taking in straw to the straw rotor 2 are planted on the outer circumference of the front end of the straw rotor 2. Then, a spoiler 2a is wound around the rear part of the straw rotor 2, and the throwing teeth 1c of the handle body rotor 1 and the scraping teeth 2b of the straw body rotor 2 are used to handle the straw. To the straw rotor 2.

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

The cut grain culms are wholly put into the handling barrel rotor 1 and subjected to threshing action, and the grains fall from the crimp net 3 onto the swing sorting device 4. Then, the grain culm after the grain has been shredded becomes straw waste and straw and is conveyed to the rear of the handling barrel rotor 1.

Then, conventionally, it was flowed straight from the rear end of the handling barrel rotor 1 and discharged, but in the present invention, from the end of the handling barrel rotor 1 to the straw discharging device provided on the already trimmed side. The straw is moved and discharged from a straw outlet 20 provided at the rear part of the straw discharging device.

(F) Embodiment The purpose and constitution of the present invention are as described above, and the constitution of the embodiment shown in the accompanying drawings will be described below.

FIG. 1 is a plan sectional view of a portion of the straw rotor 2 arranged at the rear part of the handling body rotor 1, and FIG. 2 is a rear sectional view of the same.
3 is a right side sectional view, FIG. 4 is a plan sectional view of an embodiment in which a straw spreader 14 is arranged as a straw discharging device, FIG. 5 is a side sectional view of a DC combine, and FIG. 6 is the same. It is a plane sectional view.

 The overall structure will be described with reference to FIGS. 5 and 6.

The raising reel 9 is provided at the tip of the machine body, and the grain culm caused by the raising reel 9 is platform 8
Cutting with the cutting blade provided at the front end of the platform 8
Place it on top of.

A scraper rotor provided on the platform 8 draws grain culms to the feeder chain 17 portion and conveys them to the handling cylinder rotor 1 portion by the feeder chain 17.

A crimp net 3 is provided on the lower side of the handling body rotor 1, and the grains that have passed through the crimp net 3 are sorted by the swing sorting device 4, and the fine grains fall to the conveyor 5 first,
The rice cake and the grains with spikes fall onto the second conveyor 6.

 7 is a sorting fan.

In such a configuration, as shown in the plan view of FIG. 6, the seat S is on the reaped side, and the straw rotor 2 is arranged eccentrically to the reaped side.

In the past, the end of the handle barrel rotor 1 was directly formed as a straw outlet. Therefore, since the handling barrel rotor 1 is arranged right above the swing sorting device 4 and is in an overlapping state, it is necessary to extend the handling rotor 1 further to the rear of the end position of the swing sorting device 4, and the entire length of the machine body. Was the result of becoming longer.

Next, the embodiment shown in FIGS. 1, 2 and 3 will be described.

A spiral 1a is wound around the handling body rotor 1, and sprue teeth 1c are provided at the end position of the handling body rotor 1 for guiding the throwing straw to the side of the throwing rotor 2. It is provided. And the handling body rotor shaft 10 of the handling body rotor 1
From the pulley 12 at the rear end, pull the straw rotor shaft 11 pulley
The power to 13 is transmitted and the straw rotor 2 is driven.

The spiral 2a is also wound around the outer circumference of the straw rotor 2, and the straw rotor 2 is attached to the front end from the handle barrel rotor 1 side.
The scraping tooth 2b for taking in straw is planted.

As shown in FIG. 3, the straw outlet 20 is opened downward from the end position of the straw rotor 2.

Further, the straw rotor 2 is arranged above the engine E and also serves as an engine cover.

 Next, the embodiment shown in FIG. 4 will be described.

In the case of FIG. 4, a straw spreader 14 is arranged in place of the straw rotor 2.

The straw rotor shaft 11 of the straw rotor 2 is a shaft arranged in parallel with the handling body rotor shaft 10. However, in the case of the embodiment shown in FIG. 4, the shaft 21 is perpendicular to the handling body rotor shaft 10. The straw spreader 14 arranged in the direction transfers the straw to the already harvested side.

A discharge rod 14a is projectingly provided on the outer circumference of the straw spreader 14, and the discharge rod 14a bounces the straw to the portion of the straw outlet 20.

In particular, since the straw can be bounced by the discharge rod 14a, there is an advantage that the straw can be further jumped backward.

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

Firstly, since the straw can be transferred from the handling body rotor 1 to the straw rotor 2 by means of the sprinkling teeth 1c of the handling body rotor 1 and the scraping teeth 2b of the straw discharging rotor 2, it is possible to ensure the reliability. The straw can be transferred, and the straw can be reliably discharged from the straw rotor 2.

Secondly, since the fall position of the straw can be brought closer to the already mowed side, the straw is hooked by the divider on the right side in the next process, and the straw is thrown into the handling body rotor 1 again. Has decreased.

Thirdly, since the handling barrel rotor 1 and the swing sorting device 4 are arranged in an overlapping state in the related art and the end of the handling barrel rotor 1 has an outlet, the swing sorting device 4 is more likely to end than the end. Further, it was necessary to extend the handling body rotor 1 to the rear side, which was a cause of increasing the overall length of the machine body. In the present invention, the straw rotor 2 is eccentric from the swing selecting device 4. Therefore, it is not necessary to extend the swing selecting device 4 to the end, and the length of the handling cylinder rotor 1 can be shortened and the total length of the DC combiner can be shortened.

Fourthly, when the straw outlet is opened at a position immediately after the swing sorting device 4, the dust discharged from the swing sorting device 4 tends to be closed due to the straw discharged from the straw outlet. Therefore, although the sorting wind of the sorting fan 7 is affected and the sorting accuracy is degraded, in the case of the present invention, the straw outlet and the dust outlet of the swing sorting device are located at different positions. However, the sorting wind is less affected.
