Description

[Detailed description of the invention] The present invention provides a device for holding and conveying a culm in a fallen position,
A rotary body equipped with extraction teeth that acts on the kernel tip while moving toward the kernel tip is placed below the husk tip movement path to create a gap that allows the material to be handled to fall. The rotating bodies are arranged in parallel in the culm direction with the same distance as the interval between the rotating bodies and the interval between the rotating bodies and the side wall of the handling chamber, and a sorting receiving net is provided below the rotating bodies, and a sorting receiving net is provided below the sorting receiving net. established a department,
The tip of the grain is not located between the rotating body and the sorting net, so that grain leakage through the net can be sorted well, and the handled grain can be rotated. Regarding a threshing sorting device configured to improve grain leakage efficiency and at the same time suppress grain damage by rapidly dropping and supplying grains to a receiving net through the gap between the grains, the purpose is to By rationally discharging the generated straw waste from the handling room to the sorting section, relatively large straw waste and grain culms can be separated and supplied to the sorting section, and the threshed material can be sent from the handling room to the sorting section. The purpose is to allow quick evacuation and easy modification.

The characteristic configuration of the present invention is that in the above-mentioned threshing sorting device,
Dust removal openings are provided on the handling port side of the sorting net and on the opposite side from the handling port, respectively, along the shell culm transfer direction, and an mI recorder and an outlet are provided on the side opposite to the handling port. The purpose is to provide a cover for the dust opening.

First, in the above-mentioned threshing sorting device, in the case of short culms, most of the threshing from the culms is handled by the sorting receiving net because the ridge is located on the front side of the handling port. The culm is supplied falling to a point corresponding to the mouth side, and is then fed falling to a place on the handling port side of the sorting section located below that point, and in the case of long culms, the ridge is on the opposite side from the handling port. However, due to its location on the back side, most of the granules shed from the culms fall to the location opposite to the handling port of the sorting receiving net, and are supplied to the ash extraction port of the sorting section located below that location. It is supplied falling to the side part.
On the other hand, relatively large straw waste that is generated during threshing and does not fall between the rotating bodies is transferred to the side opposite to the handling opening by the handling teeth that move on the side of the tip movement path, and is transferred to the opposite side of the handling opening between the rotating bodies and the handling chamber at that location. The straw waste falls from between the side walls to the ash outlet side of the separating net, and unless it falls from that point into the sorting section, it will not be possible to handle the top of the net. It is transferred to the handling mouth side of the receiving net by the handling teeth that move toward the mouth side.

Therefore, when threshing short culms, by opening the dust exhaust opening located at the opposite end of the handling port, the husks are mainly supplied to the handling port side of the sorting section, while relatively large straw waste is The dust is mainly supplied to the opposite side of the ill section through the dust removal opening located on the opposite side of the nozzle, and when threshing long culms, the husks are mainly removed from the ash removal section of the sorting section. While the straw waste is supplied to the mouth side, comparatively large straw waste is fed between the rotary body on the side of the reaction force and the chamber side wall, between the rotary body and the receiving net, and on the suction side. The dust is supplied to the port side of the sorting unit Ilk through the dust removal opening located at the opening. Therefore, I4. ! By adjusting the opening/closing of the dust exhaust opening on the ash extraction port side depending on the length, it is possible to feed the grain waste into the sorting section separately into the handling 1-1 side and the reaction port side. was able to be carried out efficiently.
Furthermore, in the case of shell culms that easily shed grain, regardless of whether the culm is long or short, by opening the dust exhaust opening located on the opposite side of the handling port, straw waste can be removed from between the rotating body and the side wall of the handling chamber. Not only can the dust be quickly discharged to the sorting section so that it does not mix with the grains on the receiving net, but also the dust on the handling port side and the counter port side can be removed so that the time that grains remain on the receiving net is shortened. It can be quickly discharged from the receiving opening to the sorting section, and it prevents the threshing efficiency from decreasing due to an increase in the amount of processed material remaining on the receiving net, or the grains being unnecessarily subjected to temporary action on the receiving net and being damaged. I was able to avoid the problem.

In addition, it was only necessary to make a simple modification to provide both dust exhaust openings along the shell culm transfer direction and the lid, which was advantageous from an economic point of view.

Embodiments of the present invention will be described below with reference to the drawings.

@1 As shown in Figure 1, the grains are fed to the handling chamber (2) by the threshing feed chain (1) as a clamping and conveying device, and then handled by the handling teeth (8a) of the rotating shaft (3). The threshing section is structured so that the straw is carried out from the handling room (2) by the threshing feed chain (1), and the straw is carried out from the handling room (2).

A) is installed below the handling room (2), and is a screw conveyor (7) that transports the first processed material from the sorting section (4) to the outside of the machine.
, and a screw conveyor (8) that returns the No. 2 processed material from the sorting section (A) to a handling chamber (2) to be reprocessed.
Each of these is provided at the bottom of the sorting section (4) to constitute a threshing and sorting device for a combine harvester.

The threshing section will be described in more detail. It is constructed as shown in FIGS. 2 and 8.

That is, the rotation shaft (3), in which the handling teeth (8a) are arranged in parallel so as to be integrally rotatable in each of the opening direction and the shaft direction, is rotated so that the rotation shaft (P) is in the grain transfer direction by the feed chain fi1. Transfer the grain tip while following the line! i? The upper and lower parts of the II path are arranged in parallel in the direction of the culm, and each of the rotating shafts (3) is driven to rotate in the direction of the arrow (B). The grain is moved between the four-track axis rows, and is threshed by the handling teeth (8a) which act temporarily while moving toward the ear tip side in the ear tip movement path.

Between rotating shafts (3) adjacent to each other in the culm direction, and
A gap (Sl) or (S2) is provided between the rotating shaft (3) and the side wall of the handling chamber (2a), respectively, to allow the material to be processed to fall.
A sorting receiving net (9) is provided below the rotating shaft (3), and a separating net (9) is provided at 41 of the receiving net (9) on the port 00) side and opposite to the handling port (10).
