Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a culm removal device in a screw type thresher.

(Prior Art) Generally, in a DC combine combine equipped with an axial flow thresher in which a rotor shaft and a swing selecting device therebelow are parallel, a third largest mouth is provided between the end of the swing selecting plate and a crimp net, that is, a concave. Is formed, and a recess at the end of the rotor is bored thereabove to form an outlet.

(Problems to be solved by the invention) However, in the DC type, since the whole grain culm is threshed, a large amount of treated culm and straw waste is discharged from the culm outlet, so the 3rd largest culm is culled. It becomes a state that it is covered with the curtain of the above, which obstructs the exhaust of the sorting chamber and the exhaust of No. 3 dust.

In addition, piles of culms directly underneath hinder post-work. Furthermore, the grain leaked at the end of the concave is prone to 3 loss due to irregular reflection etc. because the 3rd mouth is near, and the concave end Since it is separated from the outlet side plate and is independent, it is necessary to secure the strength.

(Means for Solving the Problems) Therefore, a partition plate protruding from the end of a handling room having a handling cylinder equipped with a screw is provided, and the partition plate and the culvert surface below the partition plate are provided outside The culm removal device in the screw type threshing machine is characterized in that a third mouth is formed as the descending inclined surface facing the.

(Example) Hereinafter, the Example shown in drawing is described.

First, the entire combine including a conventional screw thresher will be described.

In FIG. 9, the crop scraped by the scraping reel (1) and cut by the cutting blade (2) is transferred from the scraping auger (3) to the handling chamber (5) of the feeder house (4) by the chain conveyor (5). It is carried to 6) and threshed by a screw-type drum or rotor (7). The threshed ones are dropped from the crimp net, that is, the concave (8), onto the rocking sorting board (9) to be sorted. Those threshed on the rocking sorting board (9) are sorted, but only long straws are carried toward the rear dust outlet.

In addition, the items sorted by the rocking sorter (9) are sorted by the sorting wind by Kara (10), and the grains fall on the first gutter (11) and the second drop on the second gutter (12). , The grain that fell into the first gutter (11) was transported to the paddy tank via the lifting cylinder, and dropped into the second gutter (12) 2
The bait is returned to the rocking sorter disc (9) by the 2nd reduction auger.

In the present invention, in the screw threshing machine as described above, a partition plate (16) protruding into the handling chamber (6) is provided at the end of the concave (8) on the lower half of the handling chamber (6) as shown in FIGS. It is provided throughout.

(17) is a culm blade provided at the end of the rotor (7), (18)
Is an outlet.

The partition plate (16) is connected to the end of the concave as described above, but is also fixed to both side plates (19) of the machine body. Further, the lower edge (16a) thereof is bent outwardly of the machine body so as to be inclined downward. The partition plate (16) shown in the drawing has both edges raised up in an angle (16b) for attachment to the body side plate (19), and this is connected to the side plate with bolts and nuts.

Further, as an application example, it is preferable that the angle of the inclined surface (16a) is adjustable or the length can be adjusted.

The one shown in FIG. 4 shows the one capable of adjusting the angle, and the inclined surface (16a) can be swung about the axis (13) of the partition plate (16), and its angular position is fixed. Therefore, any means is adopted.

The one shown in FIG. 5 shows that the length can be adjusted. An extension plate (14) mounted on the lower surface of the inclined surface (16a) by a slit groove (14) and a tightening bolt nut (22) inserted into this groove (22). 21) is attached. And the angle of this inclined surface (16a) is the third largest
It is desirable to be parallel to the culm plane (24) at (23).

In addition, in the DC type combine with the axial flow type rotor (7) installed over almost the entire length of the threshing machine, the rotor rotates at high speed in the upper part of the machine, so the vibration given to the machine due to load fluctuations and resonance due to processed materials etc. The amount is large.

For this purpose, the front and rear support frames (25) (2
5) is a vertical frame (26) (26) (26) (26) on both sides of the thresher as shown in Fig. 6.
(26) is firmly connected to the chassis frame (2
It is necessary to adhere to 7) to increase the strength. In addition, since the DC type combine has a larger body than the self-removing type, it is necessary to climb using a ladder or the like when performing maintenance and inspection of the upper part of the body.
Although some conventional ones are equipped with a dedicated ladder, they are used only for that purpose.

Therefore, in order to increase the strength of the airframe and to improve both the points of the ladder, in the one shown in FIG. 26)
(26) The lower ends of (26) and (26) are connected and fixed to the chassis frame (27). That is, it has a gate-shaped frame structure as viewed from the rotor axis direction.

Further, in order to increase the rigidity of the vertical frames (26) (26) (26) (26), horizontal reinforcing plates (28) are arranged and fixed at appropriate intervals.

Since one of the vertical frames (25) in the figure is L-shaped, the reinforcing plate is triangular.

With the above configuration, the rotor support frame (2
5) The vertical frame (26) (26) (26) (26) (26) that relays the chassis frame (27) (27) and the rigidity is increased, and it can be composed of relatively thin members, making it a lightweight and strong airframe It becomes a frame.

Further, since the reinforcing plates (28) (28) arranged horizontally can be put on the legs, it is possible to easily climb to the upper part of the thresher from anywhere other than the driver's seat.

Therefore, both strength and maintainability can be improved.

(Effects of the Invention) According to this technical means, the straw discharged from the end of the handling room having the handling barrel provided with the screw is discharged downward by the partition plate having the descending inclined surface facing the outside of the machine body. Instead of falling on the culm, you will be guided backwards and outwards. Therefore, the mass discharged from the handling cylinder does not block the third mouth. Moreover, since the culvert surface that forms the third mouth below that is also a descending inclined surface like the partition plate, these two independent exhaust air passages are not affected by the culm from the handling cylinder. Formed, the dust is smoothly discharged and guided.

Also, since the partition plate is fixed at the end of the handling room,
The strength to withstand a large amount of straw that is culled can be secured.
