Description

DETAILED DESCRIPTION OF THE INVENTION In order to make it possible to adjust the extraction method, the starting ends of the head-side locking and conveying device and the stock-side clamping and conveying device are used to raise the planted culm in a backward and inclined position. Regarding the improvement of the transport section structure of a combine harvester configured to integrally change the vertical position near the rear of the device, it is possible to widen the adjustment range of 15-C1 handling depth so that the width of the position change can be increased. G
In addition to this, the shell culm is provided with a posture correction function for the conveying shell culm, so that even if the shell culm from the lifting device is bent, it can be delivered in an extended posture. aim at something.

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

A threshing device (2) is attached to a self-propelled machine body equipped with a crawler-type traveling device (+), and a lifting device (3) with a backward tilting posture that gives a lifting action to the planted culm (V), and a lifting device. A pre-processing device is provided in front of the self-propelled machine body, and includes a device (4) for reaping the shell culms, and a conveying section (6) for supplying the harvested shell culms to the starting end of the threshing feed chain (5). There is,
It consists of a combine harvester that reaps the planted husks and threshes the cut husks as the machine travels.

The conveyance section (6) is constructed as shown in FIG.

That is, a device (7) that locks and conveys the head side and a device (8) that clamps and conveys the stock end side extend near the rear of the pulling device (3) and above the starting end of the threshing feed chain (6). and at the terminal end of the locking conveyance device (7), the culm for delivery to the threshing feed chain (5) is arranged so that it is placed in a sideways posture in cooperation with the locking conveyance device (7). A pressing rod (9) that preferably acts on the tip side is provided, and the culm is inherited from the lifting device (3) and the reaping device (4) in an upright position, and at the end of conveyance, it changes to a sideways posture. The grains are then delivered to the threshing feed chain (5).

The two-way feeding device +71, (81) can be integrally swung and fixed around the horizontal axis (P) on the conveyance end side by the swiveling and fixing operation of a lever (10) provided in the control section. By using the lever (lO), the starting ends of the two-way feeding devices +7+ and +81 are repositioned up and down, and the clamping position of the stock-side conveying device (8) relative to the receiving shell culm is changed in the direction of the culm. Therefore, the processing depth in the threshing device (2) can be changed and adjusted.

The above-mentioned two-way feeding devices +7+ and +8+ are arranged so that the vertical interval becomes smaller on the starting end side, so that the handling depth can be adjusted over a wide range, and the lifting device (3
) is arranged so that even if it is bent, it is delivered to the threshing feed chain (5) in an extended position. That is, both sides feeding device +7+, +8+
The top and bottom of the starting end of the culm are narrowed to allow for a wide range of position changes within the limited space behind the pulling device, and the culm from the lifting device (3) is made as close to the same part as possible. Both-way feeding devices +7+ and +81 can be made to work, and the culm inheritance timings of both-way feeding devices +7+ and +8+ can be made to coincide with each other.
By making the interval between + and +8+ larger on the lower side of conveyance and giving the locking and conveying device (7) a combing function using its culm locking claws, an elongating action is imparted to the conveyed culm. This is so that it can be used.

To attach the pretreatment device to the self-propelled aircraft, as shown in Fig. 2, the pretreatment device frame (11) is attached to the self-propelled aircraft frame (
12) is connected to the upper end of a support column (13) erected at the front end thereof so as to be vertically swingable, and a fluid that drives the frame (11) to swing vertically across the frame (11) and the self-propelled aircraft body. A pressure cylinder (14) is installed in tension, and by operating this cylinder, the pretreatment device is raised and lowered to adjust the cutting height.

The strut (13) is connected to the fuselage frame (12) so as to be able to swing vertically, and a bolt (16) is inserted between the strut (13) and a member (15) fixed to the fuselage frame (12). A support lock mechanism is constructed in which the support support (13) is oscillatedly locked by the support support (13), and the lock is released by removing the bolt (16). At the time of inspection or repair, care is taken to allow the support column (13) to be lowered forward so as not to interfere with the work, as shown by the imaginary line in Figure 2.

In summary, the present invention provides the above-mentioned both-way feeding device (7) in the structure of the conveying section of the combine harvester described above.

It is characterized in that the interval (8) is made smaller on the starting end side.

That is, the starting end is located in the space where the change limit is set due to the tilting of the lifting device (3), that is, near the rear of the lifting device (3), and the starting end is placed near the rear of the lifting device (3). By reducing the distance between the +8+ and the upper and lower middles, the width of the position change can be increased, and the adjustment range of the handling depth can also be increased.

Furthermore, if the two-way feeding devices [7] and (8) are arranged in the above-mentioned configuration, their starting ends are made to act on the same part of the culm from the lifting device (3) as much as possible, and the two-way feeding devices ( 7
), +8+, and the interval between the two-way feeding devices (7) and (8) is wider on the lower side of the conveyance, which makes it possible to use the locking conveyance device (7).
) can exert a combing action, so even if the culm from the pulling device (3) is bent, it will be corrected to an extended position as it is transported, so the reaped culm will be in an extended position. It is now possible to pass it to the next action device in alignment.
