Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a technique in which an orthogonal processing cylinder is disposed at the rear of a swing sorting device in a threshing device mounted on a combine harvester.

(b) Prior Art Conventionally, a technique has been known in the art in which an orthogonal processing cylinder is disposed above the rear part of a swing sorting device in a threshing device.

For example, it is disclosed in Japanese Utility Model Application Publication No. 61-122660.

However, in the conventional configuration of the orthogonal processing cylinder, a concave was not disposed on the rotating outer periphery below the concave, and a processing cylinder chaff sheave of the swinging sorting device was also not arranged. The sieve line at the end of the swinging sorting device was swinging below the orthogonal processing cylinder 2.

(C) Problems to be Solved by the Invention The present invention provides a concave on the lower side of the orthogonal processing cylinder, and a t2 moving separation device above the concave 5, in order to more complete the processing by the orthogonal processing cylinder. The purpose is to place grains with ears and straw waste from the straw rack 13 at the end for processing.

In this configuration, when the concave 5 is provided below the orthogonal processing cylinder 2, the concave 5 is in a fixed state and the stroke rack 13 of the swing sorting device A swings back and forth, so that the stroke - It is difficult to arrange grains with ears and straw waste from the rack 13 onto the concave 5 without spilling.

In order to improve this problem, the present invention directs the sorting air from the sorting fan 21 to the gap between the straw rack 13 and the concave 5, such as the swinging first flow grain plate 7 or the fixed first flow grain plate 17. The straw is guided by the straw rack 13 and is blown up into the gap between the tip 4a of the guide plate 4 at the tip of the concave 5, thereby preventing grains with ears and straw from falling from the gap.

(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.

An orthogonal processing cylinder 2 is arranged at the rear upper part of the oscillating sorting apparatus A, and the rear end of the stroke rack 13 of the oscillating sorting apparatus A is exposed to the front part of the concave 5 at the lower part of the orthogonal processing cylinder 2. , the tip of the guide plate 4 disposed at the front end of the concave 5 of the orthogonal processing cylinder 2 is directed in a direction that almost corresponds to the rearward and upward extension line of the grain plate at the rear of the first conveyor 12. .

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

FIG. 1 is a side sectional view of the threshing device of the present invention, FIG. 2 is an enlarged sectional view of the rear part of the orthogonal processing cylinder 2 and the swing sorting device A, and FIG.
The figure is a plan view of the grain sieve 14 of the oscillating sorting device A, FIG. 4 is a side sectional view of the front part of the oscillating sorting device A, and FIG. 5 is a front sectional view showing the crimp net 15 and 6. FIG. 6 is a perspective view of the concave 5 and guide plate 4.

Let me explain about Figure 1.

Crimp m15 and m16 are arranged below the handling cylinder 1. The structure of the crimp nets 15 and 16 will be explained with reference to FIG.

The grains threshed by the handling barrel L are crimp Y115/16
The eared grains and straw waste that did not pass through the crimps m15 and 16 are passed through the openings at the ends of the crimp nets 15 and 16, and fall onto the drain pan 25 of the oscillating sorting device A. It falls onto the main chaff sheave 24.

The grains that have fallen onto the dale pan 25 are subjected to specific gravity sorting and fall onto a guide plate 3° leading to the grain sieve 14. A correction guide rib 6 is arranged on the guide plate 30 to correct the deviation of the sorted material on the swing sorting device TIA. Its role is to push falling objects to be sorted back toward the feed chain.

The grains conveyed by the correction guide ribs 6 and the guide plate 30 then fall from the openings of the grain sieve 14 while passing over the grain sieve 14. The opening of the grain sieve 14 will be explained with reference to FIG.

In addition, grains placed on the main chaff sieve 24 and dropped from a stuck state by the swinging of the swing sorting device A also fall into the grain sieve 14. The grains with ears and straw waste that have not fallen from above the main chaff sieve 24 are conveyed to the straw rack 13, and transferred from the straw rack 13 onto the guide plate 4 at the front end of the concave 5. However, since the concave 5 is fixed and the guide plate 4 attached to it is also fixed, the stroke rack 1
During the process of dropping the material from the end of the guide plate 3 onto the guide plate 4, there is some material that falls through the gap between the two.

In the present invention, the guide plate 4 and the stroke rack 13
In order to prevent the processed material from falling through the gap between the
It is configured to blow up toward the gap.

Since the oscillating first-flow grain holder 7 is integrated with the oscillating sorting device A, the wind guided by the oscillating first-flow grain plate 7 is always blown up to the end of the straw rack 13. The processed material is transported by the stroke rack 13 and placed on the guide plate 4, and then when the stroke rack 13 retreats, the processed material is transferred to the guide plate 4.
However, when the remaining processed material tries to fall from the gap, the sorting wind blows up and pushes it up from above the guide plate 4 onto the concave 5, and the processed material is transferred to the orthogonal processing cylinder 2.
It engages the rotation of the

For this purpose, a tip portion 4a is formed by bending the guide plate 4 at the tip of the concave 5 forward and downward.
The direction a is approximately aligned with the extension line of the fixed laminar flow grain plate 17 and the oscillating laminar flow grain plate 7, which are the flow grain plates of the first conveyor 12.

A concave 5 is arranged below the orthogonal processing cylinder 2,
After being processed by the orthogonal processing cylinder 2 and concave 5, the grains, grains with ears, and straw waste fall onto the processing cylinder chaff sieve 23, and only the grain portion is fixed from the swinging second flow grain plate 8. It flows onto the second flow grain plate 16.

Further, straw waste that does not fall from above the processing cylinder chaff sieve 23 is discharged from the machine body through an opening at the rear of the machine body.

Further, the second processed material that has flowed into the second conveyor 11 from the 8-moving second flow grain plate 8 and the fixed second flow grain plate 16 is transferred to the reduction thrower.
3, it is returned to the handling cylinder 1.

The grains that have passed through the grain sieve 14 fall onto the oscillating laminar flow grain plate 7, and from the movable laminar flow grain plate 7, pass over the fixed laminar flow grain plate 17, and then reach the conveyor 12. It flows in.

A suction port of a dust removal fan 28 is opened in the front side plate of the orthogonal processing cylinder 2.

Next, let me explain about Figure 2.

A first rubber sag 9 is arranged on the lower surface of the oscillating laminar flow grain plate 7, and a second rubber sag 10 is arranged at the bottom of the oscillating second flow grain plate 8.

In the conventional swing sorting device A, since there is no orthogonal processing cylinder 2, the processing cylinder chaff sieve 23 is not provided. Therefore, the oscillating sorting device A mostly uses the stroke rack 13.
Even if the fixed-laminar flow grain plate 17 and the fixed second flow grain plate 16 are configured to be longer upward, they will not interfere with the sowing sorting device 7cA.

However, in the present invention, since the processing cylinder chaff sheave 23 is provided below the orthogonal processing cylinder 2, if the extended portions of the fixed laminar flow grain plate 17 and the fixed second flow grain plate 16 are extended too far upward, they will swing. This will interfere with the sorting device A.

In order to eliminate this inconvenience, the present invention provides a fixed-laminar flow grain plate 1
7 and the fixed second flow grain plate 16 are shortened, and the conventionally long portion is configured into an oscillating laminar flow grain plate 7 and an oscillating second flow grain plate +v, 8. It is designed to be able to swing freely.

In addition, since the oscillating laminar flow grain plate 7 and the oscillating second flow grain plate 8 sway, straw waste and second reduction materials are removed from between the oscillation laminar flow grain plate 7 and the fixed laminar flow grain plate 17. Therefore, a rubber sag 9 is attached to the lower surface of the oscillating laminar flow grain plate 7.

Similarly, a second rubber drip IO is attached to the lower surface of the swinging second flow grain board 8 to prevent straw debris from entering between the fixed second flow grain board 16 and the swinging second flow grain board 22 temporary 8. It is preventing this.

As described above, the oscillating laminar grain plate 7 and the oscillating second flow grain plate 8 protrude below the oscillating sorting device A, which are connected to the fixed laminar flow grain plate 17 and the fixed second flow grain plate 1. Since it is not possible to insert and remove the swinging sorting device A from the rear opening during inspection and repair, the concave 5 part is inserted from the rear, and the swinging-laminar flow grain plate 7) 8 The movable second stream grain holder 8 is configured so that it can be folded onto the swing sorting device A side by removing the fixing bolt.

The angles of the processing trunk chaff sheave 23 and the main chaff sheave 24 can be changed by the operator from the driver's seat.

As shown in FIGS. 3 and 4, a correction guide lip 6 and a grain sheave 14 are constructed, and the grain sheave 14 has a circular opening 14a at the front and an elliptical opening 14b at the rear. .

As a result, single grains fall from the circular opening 14a, and grains with spikes fall from the oval opening 14b, thereby increasing the sorting effect.

Further, the configuration for attaching and detaching the crimp nets 15 and 16 will be explained using the configuration shown in FIG.

The crimps m15 and 16 connect two crimp nets at a hinge 17 in the center, so that the crimp nets 15 and 1 can be connected from the opening on the feed chain side as shown in FIG.
6 is constructed so that it can be folded when it is taken out for inspection and repair.

When the crimps 1i115 and 16 are stored below the handling barrel l, they are inserted along the rails 20 and 19.

Also, even if you try to pull out the crimp M15/16 after using it for a long time, it may not come out because it is rusted or gets stuck with straw debris.
It can be engaged and pulled out.

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

First, the sorting air from the sorting fan 21 flows along the fixed laminar flow grain plate 17 and the oscillating laminar flow grain plate 7, and is transferred from above the processing cylinder chaff sieve 23 onto the tip portion 4a of the guide plate 4. This makes it possible to blow up grains with ears and straw debris from below, which reduces the chance of grains with ears and straw debris falling from the gap between the two.

Secondly, since the oscillating laminar flow grain plate 7 oscillates back and forth together with the oscillating sorting device A, the wind blown from the oscillating first flow grain plate 7 at the end of the durain sheep 14 is always in the same relative position. Furthermore, the fixed laminar flow grain board 17 is a flow grain board that does not swing, and since the wind from the sorting fan 21 blows up from the fixed first flow grain board 17, the two from the two flow grain boards are The upward wind from the system facilitates the movement of grains with ears and straw debris from the oscillating sorting device to the guide plate 4, and reduces the falling of grains with ears and straw debris from this part. be.
