Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a culm removal device for a screw type threshing machine, and more particularly to a culm removal device for a screw type threshing machine in which the handling barrel of the threshing section is constituted by a screw auger.

Conventional technology The diameter of a screw auger, which was originally used to convey grain in the axial direction, is expanded and a predetermined rotational speed is applied to the screw blade to maintain the circumferential speed necessary for the crop, thereby conveying the crop. In addition to this, it also has a threshing function.

In addition, if the receiving gutter part of the screw auger at this time is changed to a receiving net of an appropriate size for the crops, the grains threshed in the handling chamber will leak downward from the receiving net, and the stems and straw waste culms will be axially moved. It will now have a so-called sorting function that transports and discharges it outside the machine.

This is a screw type threshing machine.

As shown in FIG. 6, the culm discharge section of the threshing section in a conventional screw-type threshing machine is equipped with auxiliary devices such as a beater (51) behind the screw auger (50), and thereby the culm discharge section of the threshing section is equipped with an auxiliary device such as a beater (51) as shown in the broken line (52). The stalks and culms of straw waste were being discharged outside the machine.

Problems to be Solved by the Invention Conventional screw-type threshing machines not only require an auxiliary device for shedding the culm, but also waste space in the handling room.

Means for Solving the Problems The object of the present invention is to eliminate the need for conventional auxiliary equipment.

The technical means of the present invention for solving this technical problem is that the rear end of the screw auger is extended beyond the handling chamber by one pinch or more.

Effects of the Invention According to this technical means, the culm can be directly discharged by the screw auger itself extending outside the handling room, so there is no need for auxiliary equipment such as a beater. The auger can be lengthened accordingly, improving threshing ability.

Conventionally, long pieces of straw or the like would fall from the beater or the like onto the oscillating sorting board (53), but according to the present invention, this does not occur and the sorting performance is improved.

Embodiment First, the entire screw type threshing machine shown in FIG. 1 will be explained.

The grain is raked in by the raking reel (1) and cut by the cutting blade (2), and the cut crops are transferred from the raking auger (3) to the chain-contact hair (5) of the feeder house (4) in the handling room ( 6
) and threshed using a handling cylinder (7) consisting of a screw auger.

The threshed grains fall from the receiving net (8) onto the sorting auger (9), and are moved toward the terminal end by the rotating auger (9).

During this conveyance process, grains and fine straw waste leak downward from the receiving net (9a) stretched over the receiving gutter of the auger (9), and only the long straw is carried toward the dust outlet (10).

Leakage including grains that have fallen from the receiving net (9a) is carried onto the No. 1 gutter (13) by a belt conveyor (12), where it is blown away by a winnowing fan (11). Grain falls into the first gutter (13), second grain falls into the second gutter (14),
The grains that fell into the No. 1 gutter (13) are transported to the grain frying conveyor (16).
The paddy is transported to the paddy tank (17), and the second product is returned to the handling room (6) by the second reduction conveyor.

Note that (15) is a crawler equipped with a threshing device.

The culm discharge section of the threshing section as described above is constructed by extending the rear end (7a) of the screw auger to the outside of the handling chamber (6) by one pinch or more.

Therefore, the straw etc. threshed in the handling chamber (6) is transported by the rear end (7a) of the screw auger and is transported by the arrow (a).
)l=Discharged from the machine as shown.

Since the screw auger requires a large amount of power, as shown in Figure 2, the output shaft (21) of the engine (20) is placed at the rear, and the screw auger (7) is powered by the heald (23).
directly driven. In this case, by setting the direction of the engine cooling air (22) in the same direction as the dust exhaust and the exhaust culm, the operator and the engine intake air are prevented from receiving dust. Furthermore, since the engine (20) is located at the rear end of the machine body, its weight is balanced with the reaping section that largely overhangs the front of the machine body.

In addition, the culm is located in the casing of the handling room (as shown in Figure 3).
6a) may be carried out through the discharge tube (19) provided on the rear end peripheral surface.

As shown in Figure 4.5, the second object that has fallen into the second gutter (14) is returned to the screw auger (7) by the second reducing elevator (18) as shown by the arrow (c). Let it fall naturally from above the rotation axis of the screw auger (7). And the injection angle is almost thrower auger (7)
The direction is tangential to the outer periphery.This allows the reducing materials to join together smoothly and prevents the grain from blowing back during threshing.

The arrangement of the second reduction elevator (18) is as shown in the diagram.
If the direction of rotation of the screw (7) is counterclockwise, it will be on the left side in the direction of movement of the machine, and if it is clockwise, it will be on the right side, but if it is on the left side as shown in the figure, it will be easier to clean and the paddy receiving space will be reduced. You can take a wide range of
