Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a rocking / sorting device for a thresher mounted on a combine.

(B) Conventional Technology In a threshing apparatus equipped with a combine, a technology has been conventionally known in which an orthogonal processing cylinder is arranged in the upper rear part of a swing sorting device and a dust suction fan is arranged in front of it.

For example, it is as in Japanese Utility Model Laid-Open No. 61-122660.

Further, as a technique of a swing selecting plate that swings together with a swing selecting device, a technique such as Japanese Utility Model Laid-Open No. 61-60637 is known. Also, as a technique of suspending a rubber droop,
Japanese Utility Model Laid-Open No. 59-187946 and Japanese Patent Laid-Open No. 61-14.
A technique such as Japanese Patent No. 1818 is known.

(C) Problems to be solved by the present invention The present invention is to reprocess the processed material after being processed by the orthogonal processing cylinder.
A processing cylinder chaff sheave is provided above the second conveyor in an extension of the swing sorting device to be processed by the swing sorting device.

In this way, when the orthogonal sorting cylinder is provided and the rock sorting device is extended below it to provide the chaff sheave, the swing sorting device has a length substantially over the entire length of the threshing machine, and the first conveyor or second It is no longer possible to arrange the grain board to the conveyor by extending it upward as in the conventional case.

Conventionally, since the rocking and sorting apparatus has been finished around the rear end of the grain table of the conveyor, even if the grain table is lengthened, it does not interfere with the rocking and sorting apparatus.

In this way, the present invention has a long swing selecting device,
Since it is no longer possible to extend the grain plate upward, instead swing the grain plate from the side of the swing sorting device, and after sorting by the swing grain plate, turn the grain toward the fixed side grain plate. It is configured to guide the grains.

As described above, when the oscillating grain plate is hung downward, a gap of the oscillating amplitude of the oscillating sorting device A or more is required between the oscillating grain plate and the fixed-side grain plate. However, when the gap is provided, the sorting wind may be ejected from the portion in an unexpected direction, and the spiked grains, the straw-mixed grains, and the grains may enter from other portions.

The present invention is provided with a rubber drip for closing the rocking grain plate and the fixed-side grain plate in order to eliminate the deterioration of the sorting performance due to such a problem.

(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.

In a configuration in which the processing drum chaff sheave 15 is provided above the second conveyor 6 in an extension of the swing sorting device A, the processing grain chaff sheave 15 projects downward from the swing sorting device A and is the most grain board 26 of the first conveyor 5. The most oscillating grain plate 16 is arranged in a direction parallel to the first swinging grain plate 16 from below the most oscillating grain plate 16 and on the second front grain plate 27 of the second conveyor 6. Number 1 dripping rubber

(E) Embodiments and Functions The object and construction of the present invention are as described above. Next, the construction of the embodiments shown in the accompanying drawings will be described.

FIG. 1 is a side sectional view of the thresher of the present invention, FIG. 2 is an enlarged sectional view of the rear part of the rocking sorter A, and FIG. 3 is a perspective view of the most rocking grain plate 16, and FIG. FIG. 3 is a perspective view of a second-flow grain board 17.

The overall structure will be described with reference to FIG.

The feed chain 4 is arranged outside the thresher,
Grain culms are sandwiched by the feed chain 4, and the tips of the culms are brought into contact with the handling teeth of the handling barrel 1 to shed grain.

A crimp net 13 is arranged below the handling cylinder 1, and a swing selecting device A is arranged below the crimp net 13. The orthogonal processing cylinder 2 is arranged above the rear end of the swing sorting device A, and a dust suction fan 3 is provided on the side wall on the left side of the machine body at the front position of the orthogonal processing cylinder 2 and an opening opened in the side wall. More dust is sucked in and discharged.

The front end of the swing sorting 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 rocking rod 10 and the rear rocking rod 11, the rocking sorter A can be entirely pulled out from the rear opening of the thresher during inspection and repair. Of.

A sorting and blowing fan 9 is provided below the swing sorting device A, and the grain falling from the swing sorting device A is wind-sorted by the sorting wind from the sorting and blowing fan 9 to select the first conveyor 5 and the second conveyor. It is divided into conveyors 6.

Conventionally, the processing cylinder chaff sheave 15 for selecting the spiked particles and the straw-mixed particles after the processing by the orthogonal processing cylinder 2 was not provided.

Therefore, the rocking sorter A has an important part completed near the end of the Glensieve 23, and the first side grain plate 26 and the second rear side grain plate 28, which are the stationary side grain plates, have the configuration of this embodiment. Was also extended to the upper side, and the first and second and second and third separated portions were formed by the tip portion extended to the upper side.

However, in the case of the present invention, the processing drum chaff sheave 15 for swinging and sorting the processed material of the orthogonal processing drum 2 is provided, and the processing drum chaff sheave 15 is provided in the rearward extension portion of the swing sorting device A. As a result, the first flow grain plate 26 and the second rear flow grain plate 28 cannot be extended upward.

In order to solve the problem of this point, the present invention is a swing sorting device A.
The rocking plate is supported on the side of.

The swing sorting device A is a grain pan 19 and a grain guide plate 1.
2, the main chaff sheave 14, the Glen sheave 23, the Straw rack 24, the processing drum chaff sheave 15, etc. 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 projects to the front end of the concave device B to the vicinity of the process chamber guide plate 25. The processing chamber guide plate 25 is arranged almost on the extension line of the inclination of the rocking flow grain plate 16.

The left and right side plates 21, 2 of the swing selecting device A having the above-described configuration
1 is provided with the pivotally supporting portions 21a and 21b, and the first oscillating grain plate 16 and the second oscillating grain plate 17 are pivotally supported at the portions.

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 into the pivot portions 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 swing selecting device A as a whole rearward for inspection and repair. It is when pulling out. The first rocking grain plate 16 and the second rocking grain plate 17
Has its lower end protruding more than the first-flowing grain plate 26 and the second rear-flowing grain plate 28.
It will interfere when pulling out.

Therefore, when taking out the swing sorting apparatus A, the bolts 30 and 31 fixing the upper portions of the first swinging grain plate 16 and the second swinging grain plate 17 are removed to remove the pivot support portions 21a and 21b. The most oscillating grain plate 16 and the second oscillating grain plate 17 are the two most varieties of the grain plate 2 by pulling out with the part rotatable around the center.
6 and No. 2 rear grain board 28 pushed up,
It is in a state of being stored and folded on the side of the swing sorting device A. On the contrary, even when inserting after inspection / repair, by inserting in a 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 rear part. It can be inserted without interfering with the grain plate 28.

Next, the drawings of FIGS. 2 to 4 will be described.

Since the most oscillating grain plate 16 swings back and forth, a gap greater than the width of the oscillating amplitude is required between the oscillating grain plate and the fixed-side grain plate. When the gap is opened, the most rocking plate 1
Between No. 6 and first grain plate 26, the second one is first grain plate 26
There is a possibility that it will flow toward the conveyor 5 first, and that the sorting air will blow out from the gap in an unintended direction, and the sorting performance will be degraded.

In order to prevent this, the first rubber drip 18 is arranged so as to hang from the lower surface of the first rocking grain plate 16 onto the second front grain grain plate 27.

Similarly, from the bottom of the second rocking flow plate 17 to the second rear flow plate 2
The second rubber drip 20 is hanging toward the portion 8.

As shown in FIG. 2, the main chaff sheave 14
The operator can adjust the angle, and similarly, the processing body chaff sheave 15 can also adjust the angle from the operator's hand.

The concave 8 at the bottom of the orthogonal processing cylinder 2 is the processing chamber guide plate 2
It is configured in the concave device B integrated with 5,
The thresher can be inserted and fixed from the rear side.

By removing the concave device B, the rear opening of the thresher is widened so that the swing selecting device A can be pulled out.

Reference numeral 7 is a reduction thrower for returning the second processed material collected on the second conveyor 6 to the handling cylinder 1.

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

Firstly, the most rubber dripping 18 hung downward from the most oscillating grain plate 16 is contacted not on the most grain plate 26 but on the second front grain plate 27. Since it is arranged in such a manner, when the most rubber droop 18 is extended to the tip of the most rocking flow grain board 16 as in the conventional case, the coefficient of friction of the grain flow at the most rubber droop 18 portion. However, as the present invention, the most rubber dripping 18 is the most oscillating flow. By suspending from the lower surface of the grain board 16 onto the second front portion of the grain board 27, it was possible to eliminate the factor that obstructs the flow at the lower end of the most swinging grain board 16.

Secondly, the first rubber droop 18 is hung down on the second front grain plate 27, but is selected from the gap between the rocking grain plate and the fixed-side grain plate. It is possible to solve the problem that the wind blows off to adversely affect the sorting performance, or the grain with spikes or the grain mixed with straw enters from the portion to reach the second conveyor 6.
