Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a feeder device in a combine harvester, and more particularly to a device for feeding husk to a threshing section in a combine harvester equipped with a screw-type threshing section.

PRIOR ART A screw auger used to transport rice grains in the axial direction is enlarged in diameter and given a predetermined rotational speed, and the screw blades maintain the circumferential speed necessary for the crops to transport the crops. In addition to the action, it also has a threshing function. In addition, if the screw auger's receiving gutter is changed to a receiving net of an appropriate size for the crops, the threshed grains in the handling chamber will leak downward from the fertilization site, and the stems and straw waste culms will be transported in the axial direction. It now has a so-called sorting function that allows it to be discharged outside the machine. This is a screw type threshing machine.

A conventional combine harvester with a screw-type threshing function has a feeder house in front of the threshing section that is equipped with a chain conveyor that supplies the harvested crops to a handling room.

In such a combine, the width of the threshing section and the width of the feeder house are approximately the same.

Problems to be Solved by the Invention In a combine harvester equipped with a screw-type threshing section as described above, the threshing section and the feeder house.

Since the widths are almost the same, the culm supplied to both sides of the handling chamber becomes stagnant, resulting in poor intake performance into the handling chamber.

Means for Solving the Problems Therefore, the technical problem of the present invention is to provide a combine harvester that can smoothly supply the husks transported in the feeder house to the threshing section. The technical means of the present invention for solving the problem is characterized in that the center of the width of the feeder house is located on the rotational suction side 7) with respect to the axis of the screw set handling barrel.

Effects of the Invention In the present invention, the width center of the feeder house is offset from the axis of the screw set handling cylinder toward the rotation suction side, so that the culm is supplied to the rotation suction side of the screw set handling cylinder. It has the characteristic of improving the performance of taking the grain into the threshing section.

Example The following will explain the embodiments shown in the drawings.

First, the entire combine harvester equipped with a screw-type threshing machine will be explained.

In Fig. 2, the shell culm is scraped in by a scraping reel (1) and cut by a cutting blade (2), and the trimmed shell culm is transferred from the scraping auger (3) to the chain conveyor of the feeder house (4).
At step 5), the grain is transported to the handling room (6), where it is threshed using a handling cylinder with a set of screws (7).

The threshed grains fall from the receiving net (8) to the rotating auger (9), and the rotating auger (9) moves the straw toward its terminal end, while the straw is discharged from the culm opening (6a).

During this conveyance process, the grains and rope straw waste fall downward from the catch all (10) stretched over the catch gutter of the auger (9), and only the long straw is carried toward the dust outlet (11).

Leakage including grains that have fallen from the receiving net (10) is carried by a conveyor (12) toward the gutter, and is subjected to sorting air from the end of the conveyor (12) by a fan (13) like a winnower. Grains are stored in the first gutter (15), and second grains are stored in the second gutter (14).
The grains that fell into the first gutter (15) are placed in the grain tube (1
7) to the paddy tank, and the second product is returned to the handling room (6) by the reduction conveyor (18).

(19) is a Darora equipped with a threshing device, and (20)
) indicates the cockpit.

The above is an overview of the combine harvester, but the details of each part will be explained as follows.

The bottom plate angle of the illustrated feeder house (4), that is, the angle between the direction B of the discharge of the feeder culm to the handling drum and the slope of the handling drum cone (7a) at the lowest cutting height of the combine harvester (
C) is configured to be at least a right angle or less. With this configuration, the direction of discharge of the shell culm to the handling trunk cone (rotary cone) is the same as the feeding direction of the screw at any cutting height, which improves the inheritance and intake performance and allows the supply shell culm to be discharged in a stable posture. This makes it possible to reduce losses in the threshing section.

In addition, in the illustrated fertilization (8), the part (8a) corresponding to the cone part (7a) of the handling barrel (7) is also made up of a net, and the grains threshed in the cone part are immediately sent to the auger (9). Fall towards it. This eliminates the occurrence of small grains.

Furthermore, the auger (9) shown in Fig. 3 has a screw (9
A) A protrusion (9b) is provided between the two, which presses into contact with the crimp net (10), promotes leakage of grain removal, and prevents the adhesion of dust. Three augers (9) are installed as shown in FIG. 4.

The sorting air from the Karakino (13) is routed through the air passage ('2) shown in Figure 3.
1), and its air passage (21) has a separating plate (22).
A guide plate (23) is provided at the outlet of the upper air passage (21a). Corresponding to the guide plate (23), there is a flow plate (24) for guiding grains etc. to fall from the conveyor (12).

The upper end of the grain board (25) of the first gutter (15) and the second gutter (1
The flow grain board (26) in 4) has an adjustment board (25a) (26
(a) The amount of processed materials flowing down is adjusted according to the air volume from the chisel.

In addition, (27) in Figure 2.3 is located at the culm opening (6a).
(28) in Fig. 4 is the receiving net (8).
(29) '(29) in FIG. 3 shows the guide plate for guiding leakage from the auger (9) towards the auger (12).

In addition, the lower pulley (16) of the reduction conveyor (18) is rotated either clockwise or in the direction of the half-hour hand by switching gears, etc., so that the upper conveyor blade rises or the lower conveyor blade rises. The second item can be reduced using any of the following. This makes it possible to change the direction in which the reduced material is introduced into the handling chamber.

The present invention is a combine harvester as described above, in which the width center of the feeder house (4) is offset to the rotational suction side with respect to the axis of the screw set handling barrel, and the screw set handling barrel shown in FIG. If the center line A-A passes through the axis (0) of (7) and the distances from it to both sides of the feeder house are Wl and W2, the width of the feeder house (4) is WI+W2, and Wt < W2 It is.

As described above, by moving the feeder house (4) toward the rotational suction side of the handling drum (7), the husk is supplied to the rotational suction side of the handling drum, improving the performance of taking it into the threshing section.
