Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a rocking sorting device for a threshing device.

[Conventional technology]

In the conventional thresher, many of the swinging sorters are configured to include the chaff sheave on the processed product conveying surface, and as one example, as shown in Japanese Utility Model Publication No. 1-109937,
It is known that a chaff sheave for coarse selection is installed from the front Glen pan to the rear.

Since this chaff sheave is constructed by arranging the chaflip plates side by side in the direction orthogonal to the conveying direction, it has more stable sorting performance than the Straw rack, which is formed by arranging the rack plates along the conveying direction of the processed objects side by side. There is an advantage that it is easy to demonstrate.

[Problems to be Solved by the Invention]

The oscillating sorting device has a function of transporting and discharging straw waste and the like backward on the transport surface while letting down the first product or the like to be processed and collected to the lower collecting part. However, since the chaff sheave is provided with a large number of chaflip plates in the direction orthogonal to the transport direction as described above, it becomes impossible to transport the chaff sheaves such as unbranched paddy and straw debris in a state of straddling the chaflip plate, and the shuff sheave There was room for improvement because it was likely to become clogged.

It is an object of the present invention to provide an oscillating sorting device that can exhibit good sorting performance without the above-mentioned problems.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a coarse sorting unit for coarsely sorting processed products leaking from a net by a swinging sorting apparatus of a threshing device by a Glen pan and a front Straw rack subsequent to the rear of the Glen pan. And a plurality of first rack plates arranged side by side in a rearward position of the front stroll rack, the first stroll rack for receiving and sorting the discharged matter from the dust-feeding port in a line along the processed material transfer direction. And a second straw rack composed of a number of second rack plates arranged in parallel along the processing object transfer direction is provided at a lower rear position of the first straw rack. It is provided in a state where the installation pitch is smaller than the juxtaposed pitch of the first rack plates, thereby forming a transfer surface for delivering the processed material from the Glen pan to the second Straw rack. And wherein the configuration.

Further, by arranging the front sieving line of the rear-facing cantilever plate between a large number of parallel rack plates in the front stroll rack, the parallel pitch between the front sieving line and the rack plate is equal to that of the first rack plate. It may be set to be smaller than the juxtaposed pitch.

Further, a rearward-facing cantilevered rear sieving line may be arranged below the first stroll rack with a juxtaposed pitch smaller than the juxtaposed pitch of the first rack plates.

[Work]

According to the above configuration, since the transport surface does not include chaff sheaves, there is no possibility that the padded rice, straw waste, or the like will be accumulated and clog the transport surface unlike the conventional case.

In other words, even if straw chips straddle the rack plate of the Straw rack, the rack plate is along the transport direction,
It is conveyed to the rear with the straddling state.

Then, by means of the first straw rack, the branch with a shorter length than the straw waste is sifted toward the collecting section, while the straw waste to be discharged is conveyed backward.

Most of the conveyed products on the second Straw rack following the first Straw rack are straw waste, and only a very small amount of paddy (saw paddy etc.) is mixed therein. By setting the parallel pitch of 2 to be small, while giving the last recovery opportunity to the paddy that should be recovered, the waste such as straw waste is less likely to enter the second recovery section and is reliably transported to the rear. Therefore, it is possible to prevent the threshing load from increasing due to the large amount of discharged waste such as straw waste being collected by the second collecting portion.

Most of the processed products that leak from the net are grain that has been made into single grains by threshing, but since there is also paddy with a branch that could pass through the net by chance while standing, the product according to claim 2. With the presence of the sieving line, the sieving of the unbranched paddy is also possible in the front straw rack.

According to the third aspect of the present invention, the unhulled rice that has passed through the first straw rack is sieve-sorted on the sieving line before being dropped as it is toward the collecting section.

〔The invention's effect〕

Therefore, in the swing sorting device according to the first aspect, since the straw rack is rationally arranged to form the transport surface, it is possible to provide a sorting device having improved performance while hardly causing a clogging of the processed material on the transport surface. It was possible to provide a more excellent threshing device.

In addition, in the swing sorting device according to the second aspect, in addition to the effect according to the first aspect, the rough sorting performance is also improved, so that the sorting performance is further improved.

Further, in the swing selecting device according to claim 3,
Alternatively, in addition to the effect of 2, there is an advantage that the sieve selection performance in the first Straw rack portion is improved.

The plurality of rear sieving lines (28) are arranged between the first rack plates (25a) of the first stroll rack (25), and the rear sieving lines (28) are arranged at equal intervals in the left-right direction. Yes, this is the first of the first Stroke (25)
The rack plate (25a) has the same left and right arrangement pitch (P ₁ ) as the rack plate (24a) of the front stroll rack (24), and the other rack is disposed at the center between the first rack plates (25a). The rack plate (24a) is arranged to be positioned.

That is, the rear sieving line (28) is the first rack plate (25a) 1
The racks (25a), (24a) and the rear sieving line (28) are arranged so as not to overlap with each other when viewed from the rear side.

As shown in FIG. 1, the lower grain pan (8) receives the processed material that has leaked from the receiving net (3) and passed through the Glen pan (10) and the front Straw rack (24).
After the specific gravity difference is sorted, it is oscillated and transferred to the rear Glensieeve (9), and then, while being sifted and sorted by the Glensieeve (9), it is oscillated and transferred to the rear, and is dropped and discharged from the rear end. On the other hand, the processed matter discharged from the dust inlet (1a) of the handling chamber (1) is received by the first straw rack (25), moved to the rear while sorting the leakage, and transferred to the second straw rack (26). It is discharged, and the second straw rack (26) again leaks and sorts and discharges it from the rear end to the outside of the machine. In addition, (29) is a dust-exhausting fan for discharging the dust from the machine together with the sorting wind.

The collecting part (C) collects the paddy that has leaked from the gren sieve (9), the first thing collecting part (30), and the first and second straw racks (30) discharged from the rear end of the gren sieve (9). 25) and (26), and a second material recovery section (31) for recovering the dropped rice with branches and the like.
