Description

[Detailed Description of the Invention] The present invention relates to an oscillating sorter structure in a threshing section of a combine harvester.

That is, in a swinging sorting body that is equipped with a feed pan on the starting end side and an intermediate chaff sheave below the handling chamber, a grain sheave below the chaff sheave, and a stroke rack on the terminal end side behind the chaff sheave. Depending on the amount of materials to be sorted that are tied to rice, wheat, etc. or that fall from the handling room, the material may be sent from the feed pan onto the chaff sieve,
It is possible to change and adjust the material that falls into the feed pan and send it directly to the grain sieve, improve the sorting performance and sorting ability of the oscillating sorter, and provide a simple structure that can be carried out suitably. It is something to do.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a sectional view of a threshing section mounted on a combine harvester, in which a handling chamber 7 containing a handling drum 6 is provided with a supply port 8 on one side and a straw discharge port 9 on the other side. A crimp net 10 is stretched across the lower part of the chamber 7, and a downward dust inlet 11 is formed adjacent to the crimp net 10 at the lower part of the straw outlet 9 side. A sorting dust chamber 14 is equipped with a suction port 12 and a dust exhaust port 13 at the rear, and a pressurized winch 15 is installed in the lower part of the machine from the lower side of the handling chamber 1 to the lower side of the sorting dust chamber 14. A No. 1 conveyor 16 and a No. 2 conveyor 17 are respectively arranged and configured in the same manner as the conventional structure.

A swinging sorting body A extends from below the handling chamber 7 to below the sorting dust removal chamber 14 and is installed swingably like the conventional type, but the swinging sorting body A is located below the crimp net 10. A feed pan 1 having a feeding surface on the upper surface is installed inside the starting end side of the crimp net 1.
A chaff sheave 2 having a structure in which a large number of fins 2a are arranged in an inclined manner is installed in the middle part of the swinging sorting body A which is the lower part from the dust feeding port 11 to the swinging sorting body A at the rear of the chaff sheave 2. A large number of stroke racks 4 facing above the No. 2 conveyor 17 are arranged in parallel on the terminal end side of the conveyor No. 2, and a grain sheave 3 is stretched under the swinging sorting body A which is below the chaff sheave 2 and above the No. 1 conveyor 16. Set and configure.

Further, at the lower part of the starting end side of the oscillating sorting body A below the feed pan 1, a falling plate 5 is installed diagonally so as to be lower from the starting end to the starting end of the grain sieve 3, and a support shaft fixed to the starting end of the feed pan 1 is provided. 18 is rotatably mounted on both side plates 19 of the swinging sorter A, and a support shaft 2 is fixed to the terminal end of the feed pan 1.
0 is installed so that it can move along the arcuate guide grooves 21 formed on both side plates 19, and the feed pan 1 rotates around the support shaft 18 to change its inclination from a horizontal position to an inclined position on the falling plate 5. Nuts 22 are installed on both sides of the support shaft 20 that fits into both guide grooves 21 so that they can be tightened freely.

In addition, the feed pan 1 can be installed horizontally above the flow plate 5 and can be removed as is.

Therefore, during work, if the feed pan 1 in the oscillating sorter A is held horizontally as shown in FIGS. As shown by arrow A, it is fed by feed pan 1 and sent to chaff sieve 2 while being subjected to specific gravity sorting.
The grains that leak after being sorted by the chaff sieve 2 fall into the grain sieve 3 and are sorted, and the culm cuts, etc. that are sent out from the feed pan and fed by the chaff sieve 2 are transferred to the crimp net 10 and the dust inlet 1.
The articles to be sorted falling from the first conveyor are combined and sent to the stroke rack 4 by the chaff sheave 2, and the second articles falling from the stroke rack 4 fall onto the second conveyor 17 and are oscillatedly sorted.

Also, if the nut 22 on the outside is loosened and the feed pan 1 is tilted on the falling plate 5 as shown in FIG. It flows down as shown by the arrow B onto the flow plate 5, and is not sent onto the chaff sheave 2, but directly onto the grain sieve 3 for sorting, and the chaff sheave 2 side falls from above and is covered. Only the selected items will be selected.

Note that when the feed pan 1 is removed, the materials to be sorted falling from above fall directly onto the flow plate 5 and flow directly down to the grain sieve 3 side.

In this way, the present invention is equipped with a feed pan on the starting end side and an intermediate chaff sheave below the handling chamber, a grain sheave below the chaff sheave, and a stroke rack on the terminal end behind the chaff sheave. In the oscillating sorter, a falling plate is installed diagonally from the bottom of the feed pan to the starting end of the grain sieve, and the feed pan is installed so that the slope can be adjusted or detached, so that rice, wheat, etc. Depending on the situation where the amount of material to be sorted that wobbles or falls from the handling room can change, adjustments can be made such as sending the material from the feed pan onto the chaff sieve, or sending the material that falls into the feed pan as it is to the grain sieve. It has the advantage that it can improve the sorting performance and sorting ability of the oscillating sorter, and can be suitably implemented with a simple structure.
