Description

Detailed Description of the Invention The present invention provides a combine harvester with a threshing device on one side in the left-right direction, an operating panel and a seat in front of the other side, and a grain bagging device and an engine behind it. The present invention relates to a grain storage device provided with a grain storage device.

Conventionally, in a combine paddy bagging device having this type of configuration, a paddy bag receiving section is provided below the paddy discharge gutter, and a plurality of pairs of rod-shaped hangers are provided above the paddy bag receiving section, thereby supporting a plurality of paddy bags. However, the paddy bags used for this purpose were relatively small (for example, 30 kg of paddy could be stored).
The bag had to be replaced frequently, and the large number of bags required a great deal of labor and time when storing full paddy bags in a truck or the like.

The present invention aims to eliminate these conventional defects, and uses a relatively large-capacity (for example, 100 kg of paddy) paddy bag instead of the small-capacity paddy bag. In order to reduce the number of replacements and enable efficient work, the inner periphery of the paddy bag receiving part of the bagging device is surrounded by a regulating frame in a substantially U-shape in plan view. is configured to expand toward the outside of the machine body, and a single large-capacity paddy bag is suspended inside the regulating frame, and an outlet for the paddy bag is provided on the outer side of the regulating frame. This makes it possible to reliably fill even a large-capacity paddy bag and to easily take it out of the machine.

A regulating wall 17 is provided between the auxiliary receiving portion 13 and the paddy bag portion 8, and this prevents both the auxiliary receiving portion 13 and the rice bag portion 8 from
8, there is no deformation due to mutual interference between the large bag 11 and the small bag 12.
You can be sure that each bag is full.

Next, the operation of the present invention will be explained. The paddy bag receiving part 8 is brought into a horizontal state by hydraulic operation, and the rotating side plate 2
2 in the upright position, and then operate the lever 36 to set the hanger 31 on the inside to the hooking position, take out the large bag 11 that has been preliminarily suspended from the hook 39, and attach the hanging strings 11a at the four corners to the hanger 2, respectively.
8, 28, 31, and 31, and then operate the motor forward/reverse drive switch 55 to lower the inner cylinder 43b of the paddy discharge gutter 43. While compressing the tip of the bifurcated gutter 45 by hand, Opening 11 of large bag 11
Push into b. Separately, the small bag 12 suspended from the back of the small bag hanger 48 is pulled out and set below the outlet 47 of the auxiliary gutter 46.

Therefore, when the operation is started, the paddy supplied from the grain lifting machine 41 passes through the gutter 42 and the opening 43c, and is discharged from the large bag 11 through the front and rear discharge ports provided in the bifurcated gutter 45.
is discharged towards. At this time, the large bag 11 is firmly supported by the regulating frame 9 that surrounds its sides, so even if it is a large bag, it is prevented from moving or deforming during the operation, and the supplied paddy is not unevenly distributed. Evenly deposited and completely filled without any problem.

When it is full, the sensor 25 detects that the weight of the paddy has reached the set weight and sends a signal to the alarm device 50 and the motor 44c, and an alarm sounds while the motor 44c operates and the inner cylinder of the paddy discharge gutter 43 43
b rises to block the opening 43c of the shutter, and the gutter 45 slips out from the opening 11b of the large bag 11.
b and close it with the string 11c, and then tighten the lever 3.
6 to release the forced posture holding of the inner hanger 31 so that the hanging strap 11a can be easily removed.

Next, the hydraulic cylinder 26 is operated and the paddy bag receiving part 8
When the large bag 11 is rotated and tilted, the rotating side plate 22 opens outward due to the force of the full large bag 11 to tilt outward, and quickly assumes an inclined position on the same plane as the paddy bag receiving part 8. The large bag 11 slides outward and is discharged outside the machine. At this time, the inside of the large bag 11 is
Since the structure is as shown in the figure, even if the bag is discharged in an inclined manner, the rice inside will not leak out.
Note that the outer hanger 28 is supported by a spring 29 having a somewhat strong tensile force, but when the large bag 11 slides down, the hanger 28 resists the spring 29 due to the outward downward tensile force of the large bag 11. Since the hanging cord 11a is rotated so that the tip is directed downward, the hanging cord 11a does not automatically come off and create resistance.

At that time, even if the large bag 11 tries to expand with the stored paddy, or the paddy tends to become uneven due to circulation, etc., the shape of the large bag 11 is always regulated by the regulating frame 9 that surrounds it, so that the side surface The large bag 11 can be easily taken out from the outside because it is smooth and the regulating frame 9 is formed in an expanded shape.

In the above-mentioned work, if the operator ignores the warning when the large bag 11 is full, the paddy from the grain lifting machine 41 will be supplied to the small bag 12 via the auxiliary gutter 46. The gutter 42 will not be clogged. Furthermore, if the large bag 11 becomes full at the center of the field, for example, the work for that row can be continued, the paddy harvested during that time can be stored in the small bag 12, and the large bag 11 can be released at the corner of the field. . Furthermore, even if the large bag 11 becomes full just before the end of the work, the remaining harvested paddy can be stored in the small bag 12 without replacing the large bag 11. or,
When the small bag 12 is full, the overflow sensor 49
Since this can be determined by the following, it is only necessary to replace the small bag 12 each time.

When the filling and unloading of the large bags 11 at the corner of the field is completed, the hydraulic cylinder 26 is retracted, the paddy bag receiving part 8 is returned to the horizontal position by its own weight, and the spare bag is removed from the hook 39 again, as described above. Then, manually raise the rotating side plate 22 and restart the operation.

The large bags 11 released in the field are collected using a front loader, a backhoe, etc. equipped on a tractor, and are lifted up and loaded onto a transport vehicle such as a Tortsku.

In the embodiment of the present invention, the release of the fixation of the hanger 31 by the lever 36 and the operation of the hydraulic cylinder 26 are performed separately, but the hydraulic cylinder 26 may be operated in conjunction with the release of the fixation of the hanger 31. .

In this way, the present invention erects the threshing device 3 on one side in the left-right direction on the fuselage of the combine, the operation panel 5 and the seat 6 in the front of the other side, and the grain bagging device 7 and the engine 10 behind it. The part surrounded by the seat 6, the threshing device 3, and the engine 10 is a bagging device section, and the inner periphery of the paddy bag receiving section 8 of the bagging device 7 is a regulating frame. 9 in a substantially U-shape in plan view, and the regulation frame 9 is configured to expand outward from the machine body so that a single paddy bag is suspended inside the regulation frame 9, and the regulation Since the paddy bag outlet 20 is provided on the outer side of the frame 9, the paddy bag receiving part 8
By adopting a single large-capacity paddy bag that covers the entire area, the number of times the paddy bags are replaced and the number of bags can be significantly reduced, making work more efficient. By surrounding the inside of the machine body of the rice bag receiving part 8 with the regulating frame 9 in a substantially U-shape in plan view, the rice bag is prevented from moving or deforming during operation, so that it can be ensured even with a large capacity rice bag. At the same time, the paddy bag is regulated on three sides on the machine body side by the surrounding frame 9, and the frame 9 is expanded toward the outside, and an outlet 20 is provided on this side. Even if the paddy bag has a large capacity, it is extremely easy to take it out of the machine.
