DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention provides a processing rotary body having processing teeth circumferentially provided at the end of a second screw, and processing carried by the processing rotary body. The present invention relates to a No. 2 screw in a thresher provided with a No. 2 vertical feed screw conveyor for returning a product to a sorting unit.

[Conventional technology]

Conventionally, the thresher having the above-mentioned structure is disclosed in Japanese Patent Application No.
No. 02182, which is proposed as No. 02182, is a solid screw having a constant diameter and a spiral screw wound around it like the screw used in a general thresher.

[Problems to be Solved by the Invention]

In the proposed threshing machine, when so-called wet threshing to thresh a grain culm wet by rain etc. is performed, it is because the straw scraps and rice with branches etc. collected as a second one are wet, It was found that the transport function is significantly reduced due to winding or sticking to the small diameter shaft of the No. 2 screw, and the grain sizing process may not be sufficiently performed by the processing rotator provided below it. .

The present invention, in the threshing machine of the above-mentioned configuration, while eliminating the above problems by adding an improvement to the second screw,
The purpose is to improve the processing performance of secondary products as well.

[Means for Solving the Problems]

In order to achieve the above object, in the thresher of the present invention,
The shaft portion of the second screw is formed in a large-diameter drum shape, and a tapered taper portion is provided on the shaft portion in the vicinity of the front side of the processing rotary body.

[Operation] In the threshing machine configured as described above, since the diameter of the shaft portion of the second screw becomes a relatively large diameter, straw scraps,
It becomes difficult for a second item such as paddy with branches to wind around, and the peripheral speed of the outer peripheral surface of the shaft becomes faster than that of the conventional shaft, so the centrifugal force becomes large and the adhesion of the second product can be reduced. it can.

Further, since the tapered portion is provided on the shaft portion in the vicinity of the front side of the processing rotary body, the second object can be easily carried to the processing rotary body.

〔The invention's effect〕

Therefore, even if you thresh wet and the second one is wet,
It is possible to prevent it from winding around the shaft of the No. 2 screw or sticking to it as much as possible, and it is possible to reduce the deterioration of the processing capacity due to clogging as much as possible.

Then, since the second object is smoothly carried to the processing rotary member by the taper portion provided on the shaft portion, clogging at this location is unlikely to occur.

Also, due to the large diameter of the shaft of the No. 2 screw,
The entire diameter of the No. 2 screw is increased, the speed of contact with the No. 2 screw is increased at the time of transportation, the singulation effect is increased, and the pretreatment performance until it is conveyed to the processing rotator is improved, and as a whole The reprocessing ability of the second product has been improved.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 4 shows a thresher to which the present invention is applied.
This threshing machine includes a threshing section (A), a sorting section (B), and a collecting section (C).

The threshing section (A) is one in which the handling barrel (2) is mounted in the handling chamber (1) and the receiving net (3) is stretched along the lower side of the handling barrel (2). The grain culms that are nipped and conveyed by the chain (4) are extracted by the handling cylinder (2), and the processed product is leaked and supplied onto the selection section (B).

The sorting section (B) includes a swing sorting device (5) and this swing sorting device.
It consists of Kara Minou (6) that sends sorting wind to (5). The rocking sorting device (5) is provided with a Glen pan (8) and a Glen sieve (9) in front and back in a continuous state across both sides of a frame body (7) that can be rocked and driven, and a straw in two upper and lower stages. The racks (10) and (11) are provided at the front and the rear. Then, the processed product leaked from the receiving net (3) is received by the Glen pan (8),
After oscillating and moving to the rear grain sieve (9) while sorting by specific gravity difference, non-leakage material is oscillated and transported backward while dropping and sorting the grains by the grain sieve (9), and falls and is discharged from the rear end. On the other hand, the treated product discharged from the dust inlet (1a) of the handling room (1) is received by the upper straw rack (10), and is swung to the rear while sorting the leaks and transferred to the lower straw rack (11). Released to
The lower straw rack (11) sorts out the leakage again and discharges it from the rear end to the outside of the machine. Incidentally, (12) is a dust-exhausting fan for sucking and discharging the floating dust generated in the sorting section (B) to the outside of the machine.

The recovery unit (C) is the first item recovery unit (13) for recovering the paddy that has leaked from the Glensive (9) and is discharged from the rear end of the Glensive (9) or the Straw rack (10), (11). The second item recovery section (14) for recovering the paddy with branch etc. The first item recovery part (13) has the first screw (13a) for conveying the recovered first item to one side, and the second item recovery part (14) has the second item recovered. A second screw (14a) for transporting the article to one side is provided respectively.

The end of the second screw (14a) is shown in FIGS.
As shown in the figure, four blades (15) are provided radially, and a plurality of processing teeth (16) are attached to each of these blades (15) at equal intervals in the axial direction. The processing blade (15) and the processing tooth (16) form a processing rotating body (D). The processing tooth (16) is treated in cooperation with a receiving blade (24) described later while unwinding the second material sent by the second screw (14a) to form a single particle. Also, the above-mentioned loose blade
(15) is a connecting case (not shown) due to the hammering action of the second product to further granulate it.
Feed through the inside to the starting end of No. 2 vertical feed screw conveyor (20).

As shown in FIG. 1, the second screw (14a) has a screw blade (14B) and a large diameter drum-shaped shaft portion (14A).
The shaft portion (14A) is provided with a tapered taper portion (14C) near the front of the processing rotary body (D). Further, the diameter of the screw blade (14B) is also larger than that of the conventional one due to the larger diameter of the shaft portion (14A), and the screw blade (14B) having a large peripheral speed is provided.
This makes it possible to convey the processed material while giving it a strong bending action.

The second vertical feed screw conveyor (20) is internally provided with a vertical screw so that the second feed is sent and then returned to the sorting section (B).

As shown in FIG. 2, the processing case (17) containing the processing rotator (D) has an arc shape along the locus of the tips of the processing teeth (16) and has a peripheral surface on the front part thereof. Has a cleaning opening (21). This cleaning port (21) is normally closed by a lid (22) that is bolted to the processing case (17), and if necessary, remove the bolt (23a) and remove the lid (22). It can be opened easily. The lid (22) is
Since the bolt hole (23b) through which the bolt (23a) passes is formed as an elongated hole along the axial direction, the position in the closed state can be moved in the axial direction. That is, the treated tooth (16)
By moving the lid body (22), the distance between the blade and the receiving blade (24) described later can be adjusted to an optimum distance.

As shown in FIG. 5, the receiving blade (2
4) are planted in a zigzag pattern and are inserted into the gap of the rotation locus of the treated tooth (16).

[Another embodiment]

As shown in FIG. 6, on the lid (22) that covers the cleaning port (21) of the processing case (17), the receiving blades (24) are equidistant (′) in the direction of the rotation axis of the processing tooth (16). It is also possible to provide a clearance gauge (30) which is arranged at the same time and is adjustable in movement in the radial direction of the processing tooth (16) by the nut (31).

This gap gauge (30) serves as a setting jig for positioning the blade (24) at the center of the interval between the processing teeth (16) arranged at equal intervals () in the direction of the rotation axis. is there. That is, since the gap between the receiving blade (24) and the processing tooth (16) is usually 4 to 5 mm, the lid body (22) integrally formed with the receiving blade (24) is simply treated with the bolt (23a). The gap ( ₁ ), ( ₂ ) between the receiving blade (24) and the processing tooth (16) is not the same ( ₁ ≠ ₂ ) due to the play caused by the tolerance of the bolt hole (23b) when just set in the case (17). On the narrowed side ( ₁ or ₂ ), the processed product is likely to be clogged, which may lead to a decrease in the processing capacity.

Therefore, the above-mentioned gap gauge (30) is attached to the processing tooth (1
By providing the position adjustable in the radial direction of 6), the following actions and effects are produced.

First, when setting the lid (22) to the processing case (17) in advance, set the gap gauge (30) so that the blade (24) is forcibly positioned in the center of the processing teeth (16). The position is adjusted with the nut (31) of the fixed bolt (32), and then the lid body (22) in which the gap gauge (30) and the receiving blade (24) are integrated is placed in the processing case (17). If the cover (22) is covered and the bolt (23a) for fastening the lid (22) to the processing case (17) is tightened in this state, the blade (2)
Since 4) is automatically positioned exactly in the center of the treated teeth (16), the intervals between the receiving blade (24) and the treated tooth (16) are all equal.
( ₁ = ₂ ). Then, after setting the lid body (22), operate the bolt (32) to move the gap gauge (30) to the lid body (22) side and fix it with the set (31). It does not interfere with the work as the processing rotator (D).

It should be noted that reference numerals are added to the claims for convenience of comparison with the drawings, but the present invention is not limited to the structures of the accompanying drawings by the entry.
