Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an auger device in the reaping section of a combine harvester.

In other words, in the reaping section of a combine that consists of an auger with a raking finger or a spiral that can be moved in and out, mounted in the auger gutter behind the cutting blade, the harvested material stagnates at the bottom of the auger gutter as in the past. It is possible to immediately cross-feed the grain without having to worry about it, so that it can be fed in a uniform state at all times, making it possible to stabilize the feeding and threshing, as well as improve performance, and to adapt it to the harvested product. The present invention is to provide a device that can be adjusted, can smoothly feed harvested products without causing wrapping, and has a simple structure so that it can be suitably implemented.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a side view of a combine harvester, in which a seat 7, a handle 8, etc. are installed on a driver's cab 6 constructed above the front of a threshing section C supported by wheels 5, and a threshing machine located below the driver's cab 6. A feeder gutter 10 is inclined and extends from the front part of the section C, and the front part of the feeder gutter 10 is connected in communication with the rear part, which is the middle of the auger gutter B in the lateral direction in the front reaping part. Inside, on the outer periphery of the auger barrel a in the transversely intermediate position in front of the feeder 9, a large number of raking fingers 1 that move forward and backward are arranged. An auger A constituted by winding spirals 2a and 2b in opposite directions is rotatably mounted on a shaft,
A cutting blade 3 is installed horizontally on the front side of the gutter bottom 11, which is below the auger A, and a reel 12 is rotatably mounted on a shaft in front of the cutting section, which is above the front side of the auger A. Configure similarly.

As shown in FIGS. 2 and 4, on the outer circumferential surface of the auger barrel a in the area around which the spirals 2a and 2b are wound, there is a take-in rod 4 inclined so as to have a receding angle with respect to the direction of rotation, as shown in FIG. The threaded portion 4a formed at the base of each intake rod 4
is screwed from the outside into a nut 13 fixed to the inner periphery of the auger barrel a, and a tightening nut 14 is screwed into the threaded portion 4a on the outer periphery side of the auger barrel a,
Each intake rod 4 is installed and configured so that its height can be adjusted in a state higher than the spirals 2a and 2b.

FIG. 5 shows another example, in which the structure is substantially the same as that of the previous embodiment as indicated by the same reference numerals, but the reel 1 is
The reel bar 15 in No. 2 is constructed by connecting the upper part of a rigid scattering prevention plate 16 which is always in a hanging state.

Therefore, during work, the auger A rotates as shown by the arrow A, and the harvest that is raked in by the reel 12 and cut by the cutting blade 3 is transferred to the yager A.
The grains are collected in the center by the spirals 2a and 2b, and fed to the feeder 9 by a group of raking fingers, and then conveyed by the feeder 9 in the feeder gutter 10 and supplied to the threshing section C for threshing.

In that case, the harvest that is fed onto the gutter bottom 11 of the auger gutter B, which is below the outer periphery of the spirals 2a and 2b of the auger A, will be taken in by each intake rod 4 and will remain on the gutter bottom 11. The grain is always fed horizontally by the spirals 2a and 2b, and the feed amount by the auger A remains uniform instead of increasing or decreasing as in the conventional case, and the grain is supplied to the threshing section C as it is. become.

In addition, since each intake rod 4 has a receding angle, there is no winding, and when the height of each intake rod 4 is adjusted by screwing with a nut 13, the intake can be adapted to the condition of the harvested product. You will be able to do that.

In addition, when configured as shown in FIG. 5, grains scattered from the rotating auger A and the harvested material in front of it are removed by the scattering prevention plate 16 as shown by arrows B, C, and D.
It will bounce back and be collected on the auger gutter B side.

In this way, the present invention has an auger A that has a scraping finger 1 and spirals 2a and 2b that change in and out.
In the reaping section of the combine, which is constructed by shaft-suspending the helix 2 in the auger gutter B behind the cutting blade 3, the helical 2
The outer circumferential surface of the auger barrel a in which the auger shells a and 2b are wound has a receding angle with respect to the rotation direction.
The auger gutter B
There is no longer a problem where the harvested material stagnates until a certain amount is reached on the bottom side of each intake rod 4 as in the past.
It is possible to stabilize the feeding and threshing by taking in the grain and always horizontally feeding it in a uniform state by the spirals 2a and 2b, and to improve the performance, and each taking-in rod 4 has a receding angle and causes winding. The taking-in action can be carried out smoothly without any trouble, and by adjusting the height of each taking-up rod 4, the taking-in action can be suitably carried out to suit the harvested product, and it has the feature that it can be suitably carried out with a simple structure.
