Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine for sorting grains that have been threshed in a handling room using a swinging sorting machine below the grain. [0002] Conventionally, an oscillating sorter has been arranged below a handling cylinder via a receiving net, and oscillating feed of grains and straw chips falling on the upper surface of the oscillating sorter. And the wind selection, but because the grains and straw chips on the upper surface of the feed pan are moved to the upper surface of the chaff sheave only by rocking feed on the rocking sorter, for example, multi-cutting is enlarged or the sorting width is reduced. When the grain and straw waste layers on the top of the feed pan become thicker due to downsizing, etc., or when moistening is performed by cutting and threshing grain culm with dew, etc., improvement of sorting processing capacity or improvement of grain collection efficiency There is a problem that improvement cannot be easily achieved. [0003] According to the present invention, a handling cylinder is provided in a handling room of a threshing unit, and an oscillating sorter is disposed below the handling cylinder via a receiving net. Above and behind the swing sorter
Karin to supply the sorting wind and take out the grains
No. 2 conveyor and No. 2 conveyor to take out the second thing
It is placed below the separate panel and below the handle cylinder front side.
Feed pan and chaff to be placed below the rear side of the cylinder
Place between sheave, chaff sheave and first conveyor
Install a grain sieve on the swinging sorter, and place it behind the feed pan.
The sorting wind of Karamin to be placed below
In self demolding combine supplied from the direction, the pre-fan exerting sorted wind from the lower side in front to migrate to chaff sieve against grain and Warakuzu sieve line the top surface of the feed pan rear, clamped by the feed chain Grains to be transported
Threshing the Tang at the front side below the threshing drum, and causes disposed feed pan downward, the action of selected wind chaff sieve and Gurenshibu lower that continuously provided to the feed pan rear
The mino is provided below the center part of the handling cylinder and behind the pre-fan , and the sorting wind is applied to the grains and straw chips moving from the feed pan to the chaff sieve to improve the sorting efficiency of the chaff sieve. And the like can be easily performed, and improvement of the sorting processing capacity or improvement of the grain collection efficiency can be easily achieved. In particular, in a self-draining structure in which the culm is threshed by the handling cylinder while nipping and transporting the stem side of the culm by the feed chain, most of the grains are threshed at the front of the handling cylinder and straw waste A large amount of dust is generated, and the degranulated grains and straw chips fall on the upper surface of the feed pan in an extremely thick state. However, the grains and straw chips moving backward from the sieve line on the rear side of the feed pan are reduced by the preliminary screening of the sieve lines and prefan. Side and is sent to the chaff sheave. Therefore,
By full-fledged sorting and wind sorting by chaff sieve and Karamin, the grain can be efficiently collected on the first conveyor and the sorting capacity can be significantly improved.
