Abstract

PROBLEM TO BE SOLVED: To miniaturize and lighten a connecting structure by combinedly using a connecting case respectively communicating a first gutter to a grain- lifting cylinder and a second gutter to a reducing cylinder. SOLUTION: Grains threshed and graded at a threshing part are lifted and conveyed to a grain tank from a first gutter 21 through a body side plate 25 by a first connecting case 22 and a grain-lifting cylinder 24. Not graded grains are lifted and conveyed from a second gutter 27 through the body side plate 25 by a second connecting case 28 and a reducing cylinder 30 to a swingable grading part, and graded again by the swingable grading part. The first and the second connecting cases 22 and 28 are composed of a same member, and the body side plate 25 and the first connecting case 22, and the body side plate 25 and the second connecting case 28 are each connected through a cylindrical spacer 32. The difference between the protruding distance from the body side plate 25 to the lower end of the grain-lifting cylinder 24 and the protruding distance from the body side plate 25 to the lower end of the reducing cylinder 30 is absorbed by the cylindrical spacer 32.

Below the crimping net 14, the first gutter 2
1 is laid horizontally, and the grains leaked from the crimping net 14 are the first gutter 21 and the main body side plate 25 erected on the end side thereof.
, And is lifted and transferred to a grain tank (not shown) by the first connection case 22 and the graining cylinder 24. The first gutter 21 and the fryer cylinder 24 accommodate a first helix 20 and a fryer helix 23 (see FIG. 3) having rotatable helical blades. The grains are transferred.

On the left side of the first gutter 21 in the drawing, a second gutter 27 is disposed substantially parallel to the first gutter 21, and the second gutter 27 is not leaked by the swing sheave 12 and the crimp net 14. The sorted kernels pass through the second gutter 27 and the main body side plate 25 erected at the terminal end thereof, and are lifted and transferred from the opening 31 to the swinging sorting unit by the second connection case 28 and the reduction cylinder 30. Is done. The second gutter 27 and the reduction cylinder 30 have a second helix 26 having a helical blade that is driven to rotate and a second helix 2

2 and 28 are made of the same member, and
5 and the first connection case 22 or the main body side plate 25
A cylindrical spacer is interposed in at least one of the second connection case 28 and the second connection case 28.

FIG. 3 shows the first gutter 21 and the first connection 21 with a cylindrical spacer 32 interposed between the main body side plate 25 and the first connection case 22 (or the second connection case 28). An embodiment is shown in which the case 22 and the frying cylinder 24 (or the second gutter 27 and the second connection case 28 and the reduction cylinder 30) are linked. With this cylindrical spacer 32, the first spiral 2
Absorb the difference in the length of the 0 and 2 spirals 26, the first and second spirals
Are formed of the same member so that they can be used together.

In the first connecting case 22 (or the second connecting case 28), the first spiral 20 and the fried spiral 23 (or the second spiral 26 and the reduced spiral 29) are connected to the bevel gears 39a and 39b. Are connected in a substantially orthogonal direction by a gear case 38 having a built-in gear.

Then, the cylindrical spacer 32 is integrally fixed to the spacer mounting plate 34 by welding or the like, and the spacer mounting plate 34 is mounted on the main body side plate 25, and the cylindrical spacer 32 is fixed to the first by screws 36. It is attached to the connection case 22.

FIG. 4 shows an embodiment in which cylindrical spacers 32-1 and 32-2 are integrally fixed to a spacer mounting plate 34.

The spacer mounting plate 34 is attached to the main body side plate 25.
And the tubular spacers 32-1 and 32-2 are attached to the first connection case 22 and the second connection case 28 according to the difference in the length of the first spiral 20 and the second spiral 26, respectively. The main body side plate 25 is reinforced while the first and second connection cases 22 and 28 are formed of the same member and are used in common.

FIGS. 5A and 5B show the spacer mounting plate 34.
In this embodiment, cylindrical spacers 32-1 and 32-2 are integrally fixed to each other, and the first and second connection cases 22 and 28 are linked by using the cylindrical spacers 32-1 and 32-2. . In the present embodiment, steel plates are used for the first and second connection cases 22 and 28, and the lengths of the tubular spacers 32-1 and -2 are changed as necessary.

Next, the operation will be described.

The grain that has leaked from the crimping net 14 of the swing sorting unit falls to the first gutter 21 below it, and is moved to the end side (the airframe) by the first spiral 20 provided inside the first gutter 21. It is transferred toward the main body side plate 25 erected on one side (left and right),
Further, the cylindrical spacer 32-1 penetrates through the main body side plate 25.
And the frying cylinder 2 communicated via the first connection case 22
4 to be lifted and transferred upward (the grain tank). Also,
A second gutter 27 is provided horizontally adjacent to the first gutter 21 and substantially in parallel with the first gutter 21, and unselected kernels fall on the second gutter 27, By the second spiral 26 provided inside the gutter 27, it is transferred toward the main body side plate 25 erected on the end side (one side of the body left and right), and penetrates the main body side plate 25 in the same manner as described above to form a cylindrical shape. The reduction cylinder 30 communicated via the spacer 32-2 and the second connection case 28 lifts and returns to the oscillating sorting section to be sorted again.

By the way, in a relatively small threshing machine, there is no problem in terms of the frying capacity, so that the first gutter 2
The mainstream is an orthogonal type in which the No. 1 and the frying cylinder 24 (and the second gutter 27 and the reducing cylinder 30) are connected substantially orthogonally. No. 2 system is larger than that of
4 and the lower end of the reduction cylinder 30 are different from each other, so that the first and second connection cases 22 and 2 are conventionally used.
Eight configurations were separate.

However, in the present embodiment, the first connection case 22 and the second connection case 28 are formed of the same member, so that the connection cases 22 and 28 can also be used as the squeezing type, thereby reducing the cost. In addition, even if the protrusion amount from the main body side plate 25 to the lower end of the fryer cylinder 24 or the reduction cylinder 30 is different, the protrusion amount is changed to the cylindrical spacers 32-1 and 32.
-2, it is possible to reduce the size and weight of the device. The cylindrical spacers 32-1 and 32-3
2-2 is integrally provided on the spacer mounting plate 34, and the spacer mounting plate 34 is further mounted on the main body side plate 25, thereby also serving to reinforce the main body side plate 25.

[0029]

As described above, according to the first aspect of the present invention, the first and second connection cases are formed of the same member, and the main body side plate erected on the terminal side of the first gutter is provided. First
The cylindrical spacer is interposed between at least one of the connecting case and the main body side plate erected on the terminal side of the second gutter and at least one of the second connecting case, thereby lifting the main body side plate. Even when the amount of protrusion to the lower end of the grain tube and the amount of protrusion from the main body side plate to the lower end of the reduction cylinder are different,
Since the difference in the amount of protrusion can be absorbed by the cylindrical spacer, the manufacturing cost can be reduced by configuring the first and second connection cases with the same member and sharing the same members.

According to the second aspect of the present invention, the cylindrical spacer is integrally provided on the spacer mounting plate, and the spacer mounting plate is mounted on the main body side plate, whereby the main body side plate is reinforced by the spacer mounting plate. And the size and weight of the threshing machine body can be reduced.
