Abstract

PURPOSE:To reasonably perform classifying operation after discharging by separately sending heavy dust to forward and light dust to backward in discharging the dust material discharged from dustdischarging port to shaking rack. CONSTITUTION:Grain culm fed to squeeze chamber 4 is threshed by rotating squeezing drum 2 and discharged from straw-discharging port 3 as waste straw. Then, threshed grain is fallen through classifying net 1 to classifying chamber 12 below the net and attained at shaking classifying device 10, thus classified. On the other hand, untreated material remained on the classifying net 1 is sent to treating chamber 6 and thrown out onto separating device 9 of discharged dust from dust-discharging port 5 according to rotation of treating drum 13, with being retreated. By such a way, among the discharged dust attained at the separating device 9 of discharged dust, relatively light straw scrap, etc., is sent to a direction of backward straw rack 16 by transferring rack 7 continuing of shaking and heavy grain is attained at chaff sieve 14 in front side by feeding action of returning plate 8.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a device for sorting out dust in a threshing machine, and can be used as a threshing device for a combine harvester.

[Prior art]

No conventional apparatus for sorting out this type of waste has a structure similar to that of the present invention.

[Problem that the invention seeks to solve]

This invention aims to reduce the loss of waste discharged outside the machine as much as possible by accurately sorting and recovering the dust discharged from the handling room to the sorting room via the processing room. It is in.

First of all, the first invention is that when discharging the dust discharged from the dust exhaust to the swinging shelf, heavy objects (mainly containing grains) are moved forward, and light objects (mainly straw, etc.) are ) is separated and sent to the rear in order to rationalize the subsequent sorting action.

Next, the second invention is to evenly distribute the dust discharged from the processing chamber onto the sorting shelf to eliminate unevenness and to perform highly accurate sorting. .

[Means to solve the problem]

This invention takes the following technical means to achieve the above-mentioned object.

That is, the first invention comprises a handling chamber 4 in which a handling cylinder 2 is pivoted above a sorting net 1 and a straw 113 is formed at the end thereof, and a handling chamber 4 that communicates with the handling chamber 4 and extends rearward from the handling chamber 4. A processing chamber 6 whose side is discharged Ify4+15, a rearward transfer rack 7 on the h side and a forward reflux plate on the lower side at a position to receive the dust a discharged from the dust exhaust port 5. 8 and a dust separation device 9 which is swingably provided; and the dust separation device 9.
A second invention is a dust sorting device for a threshing machine comprising a swinging sorting device 10 provided below a sorting screen 1.
A handling chamber 4 in which a handling IBM 2 is mounted on a shaft and a discharge port 3 formed at the end thereof is connected to the handling chamber 4 and extends rearward from the handling chamber 4, and a dust exhaust 115 is provided on the side. 1- in the processing chamber 6 and the position where the dust a discharged from the dust exhaust port 5 is received.
, a rearward transfer rack 7 on the side and a forward reflux plate 8 on the bottom side.
a dust separator 9 configured to be swingable, and
Oscillating sorting device 1 provided below the waste separation device q 9
In a threshing machine consisting of
Make up 5! This is a dust sorting device in which the side inner plate 11 has a steep slope on the side closer to the handling chamber 4 and a gentle slope on the far side.

[Action/Effect]

First, let's explain each rotating part! During J+L, the husks supplied to the handling chamber 4 are threshed by the handling drum 2 that rotates once, and then discharged from the dumping box 113 as waste straw.

Then, the threshed grains leak through the Y4 separate screen 1 into the lower sorting chamber 12, reach the swing sorting device 10, and are sorted.

On the other hand, untreated materials that have not leaked from the 5 sorting net 1 are sent to the processing chamber 6, where they are reprocessed and transferred from the JIX n 5 onto the waste separation device 9 as the processing 11 and 13 rotate. released.

In this way, the waste that has reached the waste separation device 91-, relatively light straw waste, etc., is removed from the transfer rack 7, which continues to swing.
The heavy grains are sent toward the rear stroke rack 16 by the reflux plate 8, and the heavy grains reach the chaff sieve 14 on the front side by the feeding action of the reflux plate 8.

Therefore, the grain is simply lowered into the oscillating sorter 10.1
This results in a longer sorting process compared to those that fall to the ground and are sorted, so that they are carefully selected and collected reliably. Also,
As soon as the straw leaves the dust exhaust 11, it is sent to the rear by the transfer rack 7, so that it seems like a waste of time.
It almost never lags and stays in that position.

Further, in the second invention, the dust is uniformly dispersed by the upper guide plate 11 constituting the exhaust jlXn5 of the processing chamber 6, and the dust is transferred to the dust separator 9. distributed in humans.

Therefore, the amount of dust is 1. There is no bias in the subsequent sorting action, and the entire width is reliably sorted.

〔Example〕

In the handling room 4, a sorting net 1 is stretched below and a handling cylinder 2 is mounted on an axis.
A shell culm supply port 15 is opened on one side, and a straw [ ] 3 is formed on the other side.

The processing chamber 6 has the processing cylinder 13 mounted on an internal shaft, and the starting end side is ^;1
It communicates with the storage room 4, extends rearward from the storage room 4, and provides a dust exhaust 115 in the extended portion.

And that exclusion j1! II 1. As shown in Fig. 3.4.5, the upper inner inner plate 11 constituting the
The inclination angle on the side near the processing chamber 6 is made steeper so that the waste can be discharged near the processing chamber 6, and then the dust can be discharged further away.
It is constructed on a gentle slope.

Dust storage room! The lIt device 9 is composed of an upper transfer rack 7 and a lower flow plate 8 for communicating the grains forward, and is provided below the dust outlet 5.

The swinging sorting device 10 is located long in the front and back under the waste separation device 9, and includes a chaff sieve 14° grain sieve 1
7. The stroke rack 16 is configured to be able to swing together.

Incidentally, the second invention is a direct rocking sorting device 10 for removing dust.
It is also possible to adopt a configuration in which the dust can be discharged upward, that is, a configuration without the waste separation device 9.
