[Industrial applications]

 The present invention relates to a swivel combiner in which a combine main body can be swiveled with respect to a traveling carriage.

[0002]

[Prior Art]

 In the conventional combine harvester, a combine main body including a mowing device and a threshing / sorting device is fixedly attached to a crawler-type traveling carriage with its front portion facing the front side of the traveling carriage.

As shown in FIG. 5, a general procedure for mowing rice etc. by such a fixed combine is to mow around a rectangular mowing section a for several turns, and to make headlands b 1 and b 2 before and after the section. Was formed, and then straight line cutting was repeated to mow the entire section. In this straight-cutting, one side end of the section is straight-cutted c1, and then the direction is changed 90 degrees counterclockwise to f1 to run idly on the headland b1 at one end f2, and at the other side end to the left. After making a straight-line trimming c2 on the other side edge by making a 90-degree direction change f3 and then making a left-hand 90-degree direction change f4 after this straight-line mowing, idle running f5 on the other end headland b2. , Again, a 90 ° left-handed direction change f6 was performed and a straight line cutting c3 on one side end was performed.

The time required for this mowing is about 15 to 20 seconds for straight cutting, when a standard rectangular section a having a length of about 100 m and a width of about 15 m is taken as an example. is there. After straight cutting of one side edge and straight cutting of the other side edge, it takes about 5 to 6 seconds for turning 90 degrees counterclockwise, and about 5 to 10 seconds for idle running on the headland. It took about 5 to 6 seconds to make a 90 ° counterclockwise turn again, so in the end, it took at least 15 seconds to make a 180 ° turn from one straight line cutting to the next straight line cutting. It took time.

[Problems to be solved by the device]

 When using such a conventional combine, there were the following various problems. Since the idle time required to change the direction of the combine was long, which was comparable to the time required for straight-row cutting, there was a problem with poor combine work efficiency.

[0006] The work with the combine harvester requires efficient drainage of rice from the rice fields and dryness of the rice leaves and stems. Where there is a need to do this, conventional combine harvesters have limited work efficiency as described above, and due to the historical background that it is difficult to secure a labor force, etc. With the intention of increasing the number of cuts, there is a tendency to introduce four-row cutting rather than three-row cutting, five-row cutting rather than four-row cutting, and a large combine with a larger number of cuttings. However, it is inevitable that the conventional way of thinking that the efforts to improve work efficiency will be slashed to the introduction of combine harvesters with a larger number of strips will inevitably result in higher costs due to large investment and traffic laws. Due to this, there is a limit to the size increase.

When changing direction, one crawler is stopped and only the other crawler orbits, so traveling devices such as guide wheels for guiding the crawlers are very easily worn, and a large amount of cost is required for replacement. There was a problem.

[0008] Since the combine runs many times in the fixed place of the headland, the cultivator is damaged and the soil is deeper than other parts, which causes uneven growth of rice etc. in the next year. There was a problem. There was also a problem that the crawler was caught in the turning direction and it was difficult to change the direction smoothly. An object of the present invention is to provide a swivel combine that can solve all of the above problems.

[0009]

A swivel combine according to the present invention is capable of swiveling a combine main body including a mowing device and a threshing sorting device in a horizontal plane on a support portion provided on an upper portion of a crawler type traveling carriage. The feature is that the combine body can be fixed to the traveling carriage in this state by supporting and turning the reaping device by 180 degrees.

In the swivel combine according to the present invention, it is preferable that the mowing width of the mowing device is set substantially equal to the width of the traveling carriage so that the mowing device performs mowing over the entire width of the traveling carriage. Further, it is preferable that the control path such as the hydraulic path is switched with the turning of the combine body so that the forward / backward lever operation of the combine is the same regardless of the direction change of the mowing device accompanying the turning. ..

[0011]

[Action]

 However, after performing straight-cutting on one row, in order to change the direction of 180 degrees for straight-cutting on the next row, after finishing straight-cutting on one row, enter the headland with a gentle curve. Then, the next row of straight strip cutting is ready. After that, the combine body is turned 180 degrees to turn the harvesting device in the opposite direction, and in this state, the combine body is fixed to the traveling carriage. When the mowing width of the mowing device is set to be approximately equal to the width of the traveling carriage, even if the straight row mowing of the next row is performed as it is, there is no risk that the traveling carriage tramples on the rice to be harvested.

[0012]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 to 3, in a swivel combine 1 according to the present invention, a combine main body 6 including a mowing device 4 and a threshing selection device 5 is mounted on a support portion 3 provided on an upper portion of a crawler type traveling carriage 2 in a horizontal plane, for example. It is supported so that it can be rotated 360 degrees, and the direction of the reaper 4 is changed by 180 degrees so that the state shown in FIG. 2 changes to the state shown in FIG. 3 or vice versa. In this state, the combine main body 6 can be fixed to the traveling carriage 2.

Further, the mowing width of the mowing device 4 is set to be substantially equal to the width of the traveling carriage so as to perform mowing over the entire width of the traveling carriage 2. As a result, the straight cutting of the next row can be performed immediately after the straight cutting of one row is completed.

It should be noted that the lever operation for moving the combine forward and backward in the driver's seat is configured such that the control path such as the hydraulic path is switched by the turning so that the same operation is performed regardless of the change in the orientation of the mowing device 4 accompanying the turning. Is preferable from the viewpoint of improving safety.

The operation of changing the direction of the swivel combine according to the present invention will be described with reference to FIGS. 2 to 4. First, the headland 7 is formed by cutting around, and the straight line cutting 9a of the side end is performed. After the completion of this straight-row mowing, a gentle curve is entered into the headland 7 as indicated by an arrow F to enter the straight-row mowing state of the next row as shown in FIG. After that, the combine body 6 is turned 180 degrees counterclockwise or clockwise to turn the harvesting device 4 in the opposite direction as shown in FIGS. In this state, the combine body 6 is fixed to the traveling carriage, and the straight row cutting 9b in the next row is performed.

[0016]

[Effect of the device]

 The present invention has the following excellent effects. According to the present invention, the operation of changing the direction of the mowing device by 180 degrees can be easily performed within a very short time (for example, within 3 to 4 seconds) by turning the combine body. Therefore, unlike the conventional combine that required at least about 15 seconds before the next straight line cutting was taken, the idle time for direction change was drastically reduced to significantly improve the work efficiency. Will be Therefore, when the swivel combiner according to the present invention is introduced, the same result as that of the combiner having the ability of one class is introduced, and the cost can be significantly reduced.

Since the direction of the combine is changed by the turning operation of the combine body, the movement of the crawler-type traveling carriage in the straight-cutting stage almost repeats forward and backward movements, and the traveling device is not overpowered. Therefore, the durability of the most important part of the undercarriage can be improved and the life of the combine can be extended.

Since the direction is changed by the turning operation of the combine body, it does not cause headland damage by repeatedly traveling in a limited area of the headland as in the past, and causes uneven growth of rice. The conventional problems such as the above can be solved.
