Description

[Detailed description of the invention] The present invention is a threshing section equipped with a second grain returning device to the handling room, in which the first grain of a size covering almost the entire area is placed at the lateral outer position where the second grain returning device is present. This invention relates to a threshing machine equipped with a storage tank.

In this type of threshing machine, the second grain returning device often gets clogged because a large amount of straw waste is mixed in the second grain returned to the handling chamber of the threshing section. At this time, conventionally, a method was used to remove the entire tank from the machine frame to form an open space outside the second grain reduction device for use in removing the clog, but in this case, It took a lot of effort and effort to attach and detach the tank, and maintenance such as removing clogs was difficult.

An object of the present invention is to realize easy maintenance by rationally modifying the first grain storage tank.

The characteristic structure of the threshing machine of the present invention, which has been made to achieve such an object, is that the tank portion of the tank corresponding to the second grain reduction device and the other tank portions are configured to be freely divisible, and that this division is possible. The tank portion is configured to be movable to form an open space outside the second grain reducing device.

In other words, when a clogging phenomenon occurs in the second grain reducing device of the threshing section, by moving a part of the tank corresponding to this second grain reducing device with respect to other tank portions, the second grain reducing device can be removed. Since a wide open space for clearing clogs can be formed outside the device, preparatory work for maintenance such as clearing clogs can be done easily and efficiently with less effort than when moving the entire tank. I was able to do well.

Hereinafter, embodiments of the present invention will be described based on the drawings.

To configure a combine harvester, which is an example of a threshing machine,
As shown in FIGS. 1 to 3, a threshing section 4 equipped with a second grain return device 3 to the handling room is mounted on a machine frame 2 having a crawler-type traveling device 1. At the lateral outer position where the second grain reducing device 3 is present, there is a first grain storage tank 5 having a size that covers almost the entire front and back width of the threshing section 4, and a first grain storage tank 5 that covers almost the entire width of the front and back of the threshing section 4, and a first grain storage tank 5 that is used for threshing and sorting in the threshing section 4. A grain lifting device 6 is provided to lift and transport the grain to the upper part of the tank 5, and at the front of the machine frame 2, a planted grain culm is pulled up and harvested, and then transferred to the threshing section 4. A reaping section 7 for conveying and supplying grains and a control section 8 are provided, and a disk-shaped cutter 9, which is an example of a waste straw processing device, is attached to the rear of the threshing section 4.

Then, the second half tank portion 5A of the first grain storage tank 5, which corresponds to the second grain reduction device 3, is rocked around the vertical axis _P1 on the outside with respect to the other first half tank portion 5B. The second half tank portion 5A is configured to be able to move and be fixed in the desired tank posture, and by swinging the second half tank portion 5A to a state where its outer surface contacts or approaches the outer surface of the first half tank portion 5B, A wide open space can be exposed on the outside of the second grain reducing device 3 for operations such as removing clogs and inspecting.

The bottom portion 5b of the first half tank portion 5B is formed into a substantially V-shape when viewed from the front, located at the lower part of the width center thereof, and a screw is provided within the V-shaped bottom portion 5b for forwarding and transporting the stored grain. The conveyor 10 is mounted on an axis, and a device 11 for taking out the grains conveyed by the screw conveyor 10 to the outside is mounted on the front wall of the first half tank portion 5B.
has been established.

In addition, the bottom portion 5a of the second half tank portion 5A,
The grain is arranged in an inclined position so that it can be guided in a natural downward direction to the conveyance start end of the screw conveyor 10.

FIG. 4 shows another embodiment, which is a rear tank portion 5A corresponding to the second grain reduction device 3.
is the horizontal axis that is also the rotation axis of the screw conveyor 12 for carrying out stored grain installed at the bottom of the tank 5.
By swinging laterally outward around P ₂ , an open space for clearing blockages, inspection, etc. can be created outside the second grain reducing device 3 .

Further, as another embodiment, a tank portion 5A of the tank 5 corresponding to the second grain reducing device 3 may be configured to be slidable laterally outward. still,
Although reference numerals are written in the claims section of the utility model registration for convenience of comparison with the drawings, the present invention is not limited to the structure of the attached drawings by such entry.

Claims (1)

[Scope of Claim for Utility Model Registration] 1. In the threshing section 4 equipped with the second grain returning device 3 to the handling room, there is a first part of the size extending over almost the entire area at the lateral outer position where the second grain returning device 3 is present. In a threshing machine provided with a grain storage tank 5, a tank portion 5A corresponding to the second grain reduction device 3 and another tank portion 5B of the tank 5 are configured to be freely divisible, and this divided tank portion 5A is configured to be movable to form an open space outside the second grain reducing device 3. 2. The threshing machine according to claim 1, wherein the means for opening and moving the divided tank portion 5A is rocking around a vertical axis. 3. The threshing machine according to claim 1, wherein the means for opening and moving the divided tank portion 5A is rocking around a horizontal axis. 4 Utility model registration claim 1, in which the means for opening and moving the divided tank portion 5A is sliding movement.
The threshing machine described in section.
