Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a DC combine.

(Prior Art) In a combine that feeds cut culms to the threshing section through the chain conveyor of the feeder house, a rubber that is connected to the end of the feeder house at the joint between the threshing section inlet supply plate and the feeder house and that contacts the inlet supply plate. The shape of the end surface of the sheet is vertical to the inlet supply plate as in JP-A-60-244233.

(Problems to be Solved by the Invention) In the above, residual particles are likely to accumulate in the vertical portion of the end surface of the rubber sheet, and the rubber sheet moves on the inlet supply plate as the feeder house rotates. At this time, since the vertical area for pushing up the paddy is large, it is easy to flip the paddy upward, and the paddy is taken in under the rubber, which causes paddy leakage.

(Means for solving the problem) Therefore, the technical problem of the present invention is to obtain a direct current combine without leakage of paddy from the joint between the threshing part inlet supply plate and the feeder house. The technical means of the present invention is to combine the cut grain culm to the threshing section through the chain conveyor of the feeder house, and connect the base end to the end of the feeder house at the joint between the threshing section inlet supply plate and the feeder house. A rubber sheet extending toward the inlet supply plate is provided, and the thickness of this rubber sheet is made thinner toward the lower transfer side so that the surface of the rubber sheet is closer to the lower transfer side of the inlet supply plate. is there.

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

First, the entire DC combine will be described.

In Fig. 3, the grain culm is scraped by the scraping reel (1) and the cutting blade
The grain culm that was cut in (2) was cut from the scraping auger (3) in the chain conveyor (5) of the feeder house (4) in the handling room (6).
It is then transported to and threshed by the screw type handling cylinder (7).

The threshed pieces fall from the rope (8) onto the rocking sorting board (9) and are sorted.

Those threshed on the rocking sorting board (9) are sorted, but only the long straws are carried toward the rear dust outlet. Also, the items sorted by the rocking sorter (9) are sorted by the sorting wind by Kara (11) or the blowing wind by the blower fan (12), and the grain is the second gutter (13) and the second one. The thing fell to the second gutter (14), the grain dropped to the first gutter (13) is carried to the paddy tank (not shown) through the lifting cylinder (15), and the second one is the reducing cylinder (16). Swing sorter through (9)
Carried on. Straws from the handling room (6) are discharged outside from the discharge port (6a) by the discharge wings (7a). (17) is a crawler equipped with a thresher, (18) is an elevator cylinder of a feeder house, (19) is a divider, and (20) is a driver's seat.

Further, a double pitch screw (24) is formed in the cone portion (7b) of the illustrated screw type handling body (7), and this is connected to the screw (22) of the handling body. There is a dust delivery valve (26) operated by a handle (25) on the inner surface of the upper part of the handling room. The other (30) is a sled formed under the platform, and three slats are provided in the width direction.

In the combine as described above, in the joint between the conventional threshing part inlet supply plate (27) and the feeder house (4), there is a rubber sheet (28) that is connected to the end of the feeder house and is in contact with the inlet supply plate. End face shape is inlet supply plate
It is formed straight and vertically toward (27).

Therefore, the residual particles are likely to accumulate on the end surface (28a) of the rubber sheet (28), and the pad is pushed up upward because it moves with the rotation of the feeder house (4). It was the cause of the paddy leakage.

Therefore, in the present proposal, the rubber sheet (2
The thickness of 8) is made thinner toward the lower transfer side.

This is shown in FIG. 2 (28a).

By forming as described above, the padding-up end surface area of the rubber sheet (28) is reduced, and the accumulation of residual particles is reduced.

Also, when the feeder house rotates, the paddy easily flows into the feeder house, the amount of pushing up the paddy is reduced, and the resistance is low, so the end face does not bend upwards, so the rubber sheet (28) and the entrance Less paddy between the supply plates (27) and less paddy leakage.

In the figure, (29) and (29) are sprockets on the side of the inlet supply plate (27) on which the chain conveyor (5) in the feeder house (4) is stretched, and the chain (5) is provided at regular intervals. A plurality of feeder slats (31) as a crop transfer body are laid horizontally.

(Effect of the Invention) According to this technical means, since the thickness of the rubber sheet is made thinner toward the lower transfer side, the end area where the residual rubber particles are accumulated in the sheet is reduced and the accumulation of residual particles is reduced.

Further, when the feeder house is rotated, the paddy easily flows into the feeder house, and the amount of pushing up the paddy is reduced.

Furthermore, since the sheet rubber does not flip up upward, there is less pinching of the paddy between the rubber sheet and the inlet supply plate, and there is a feature that the paddy leakage is reduced.
