Description

Detailed Description of the Invention (a) Field of Industrial Application The present invention relates to a grain recovery apparatus for combine harvesters.

(B) Conventional technology The combine grain tank is generally arranged behind the engine and laterally of the threshing unit. However, when the grain tank is arranged in this region, Since the outside of the power transmission mechanism, the lifting cylinder, and other various mechanisms installed on the lateral side portion of the threshing section is covered with the Glen tank, maintenance of the various mechanisms cannot be performed under the condition.

Therefore, the front end portion or the rear end portion of the Glen tank is rotatably attached around the vertical axis, or the Glen tank is provided so as to be horizontally movable outward along the guide rail,
Conventionally, during maintenance, the Glen tank is moved from a predetermined position to the outside of the machine to open the lateral side surface of the threshing unit.

(C) Problems to be solved by the invention By the way, the latter of the conventional techniques, that is,
In the case where the Glen tank is horizontally moved outward along the guide rail, it is possible to bring out the maintenance work space between the threshing unit and the Glen tank by pulling out the Glen tank to the outside of the machine. Since the Glen tank still exists outside the space, the maintenance work space is restricted, and the problem that it is difficult to work remains.

In that respect, in the former of those described in the related art, that is, in the case where the front end portion or the rear end portion of the Glen tank is rotatably attached about the vertical axis and the Glen tank is rotated about the vertical axis,
Since the side part of the threshing part is opened by turning and retreating the Glen tank, the maintenance work is easier than the latter one, but this causes another problem described below. It was

That is, as shown in FIG. 7, when the Glen tank (102) is rotated about the vertical axis (O), the inner corner of the Glen tank on the side opposite to the vertical axis (O) is Since it moves in an arc so as to approach an adjacent device (for example, an engine part), it is necessary to set a distance to avoid interference with the adjacent device. If you want to keep the capacity as large as possible, you should try
Since c) is cut into an arc shape, it becomes a special Glen tank shape, which is disadvantageous in terms of cost, manufacturing, and various other aspects.

The present invention has been carried out focusing on the above-mentioned problems in the prior art. The purpose of the present invention is to make the Glen tank a simple rectangular shape and to secure a large capacity, while maintaining a large capacity. In some cases, it is an object of the present invention to provide an improved grain recovery apparatus for combine harvesters that can widely open the lateral outside of the threshing section.

(D) Means for Solving the Problem In order to achieve the above-mentioned object, the grain collecting apparatus for combine harvester according to the present invention is configured so that a grain tank disposed at a lateral side portion of a threshing section is rotated to the outside of the machine. It is tiltable or slidable, and provided so as to be rotatable around the vertical cylindrical portion of the grain carrying-out device that is connected to the Glen tank, and the Glen tank is linear outside the machine in plan view. After that, it is characterized in that it can be horizontally rotated at the moving position with the vertical cylindrical portion as a center to be retracted to a position where the lateral side portion of the threshing portion is opened.

(E) Action In the combine in which the grain collecting device according to the present invention is implemented, the Glen tank is tilted or slid to the outside of the machine body, and then rotated about the vertical tube portion of the grain carrying-out device. And the Glen tank is retracted from the position that covers the lateral side of the threshing part, and the outside of the various mechanisms installed on the lateral side of the threshing part is widely exposed and opened. Therefore, maintenance of various mechanisms can be easily performed.

In the present invention, the Glen tank (2) is installed with the following structure.

The front and rear shaft ends of the bottom auger (9) provided at the bottom of the Glen tank (2) are projected outside the tank, and the rear shaft end is linked to the bottom auger (9) by the transmission mechanism (10). A vertical cylindrical portion (4) containing the auger is connected and connected through a connecting cylindrical portion (11), and an auger interlocking with the auger of the vertical cylindrical portion is provided at the upper end of the vertical cylindrical portion (4). The upper auger cylinders (12) are connected in series, and a series of grain carrying-out devices (3) are constituted by them.

Then, the vertical tube portion (4) of the grain carrying-out device (3) is fixedly provided to the machine body by the attachment tool (13), and the connecting tube portion (11) interposed at the lower end thereof is the vertical tube. It is rotatably provided around the auger axis (P1) of the portion (4). Also,
The lower front cylinder part of the Glen tank (2) is rotatably fitted to the connecting cylinder part (11) so that the whole Glen tank is attached to the connecting cylinder part (11) about the axis of the bottom auger (9) ( It is connected so that it can rotate around P2).

On the other hand, the front shaft end of the bottom auger (9) is interlockingly connected to the drive mechanism (15) via the transmission joint (14), and by moving and maintaining the transmission joint (14) at the cutting position. , It can be completely separated from the drive mechanism (15).

In addition, (16) and (17) are bearing portions, and these bearing portions are supported by a support portion (not shown) extending from the connecting tubular portion (11). Further, (18) is a fried-cylinder device for feeding the grains from the threshing section into the Glen tank, and the communicating portion with the Glen tank can be separated as necessary. Further, (19) shows a transmission mechanism and the like installed on the lateral side surface of the threshing section.

The grain tank (2) installed in the combine with the above-mentioned structure is normally positioned as shown by the solid line in FIGS. 1 to 3, and by an appropriate fixing means not shown. It is fixedly maintained and is in a position to carry out the combine work.
