Description

[Detailed description of the invention] The present invention relates to a reaping/harvesting machine equipped with a pair of forced pulling paths on the left and right sides, and is used when working in a so-called split state where the non-reapable stem culms are located on both the left and right sides of the machine. However, even when working in a so-called round mowing state where the non-reapable stem culm is located only on one side of the machine body, it is possible to smoothly divide the grass between the reapable stem culm and the non-reapable stem culm. It is also an object of the present invention to enable smooth division of the stem culms to be reaped toward each pulling route during circular mowing, and to enable this to be done advantageously in terms of cost.

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

A threshing section 2 is mounted on a machine base equipped with a crawler traveling device 1.
A device part 3 for separating the planted grain culms into objects to be reaped and objects not to be reaped, a device part 3 for raising the objects to be reaped, a device part 4 for raising and reaping the grain culms, and a part for reaping the grain culms. A pre-processing device equipped with a conveying device part 5 that supplies grains to the starting end of the threshing section 2 is provided in front of the traveling machine base, and constitutes a combine harvester that reaps planted grain culms and threshes grains as the machine travels. It has been done.

The weed pulling device section 3 is constructed as follows.

That is, two forced lifting devices A configured to move the lifting claws 6 upward while protruding from the case 7 are arranged side by side on the left and right sides of the machine, and a second device A is arranged in parallel in the lateral direction of the machine between them. In addition to forming the first and second forced pulling paths 8 and 9, the weeding claw 10 is configured to be moved upwardly by the transmission force from the pretreatment drive shaft 25 while protruding forward from the case 11, and the lower end Fixed weeding tool 1 located in the
A first forced weeding device 13 equipped with a weeding device 2 is provided on the lateral outer side of the first forced pulling path 8. Then, a second forced weeding device 14 configured similarly to the first forced weeding device 13 is positioned between the forced pulling path 8 and the second forced pulling path 9, as shown in FIG. At the same time, a transmission case 15 extending laterally from the upper end of the case is connected to the first forced weeding device 1.
The lower end of the case is separably connected and fixed to a transmission case 16 extending laterally from the case 11 of No. 3, and the lower end of the case is separably connected and fixed to a first frame 18 extending from the preprocessing device frame 17. 1 working position;
As shown in FIG.
5 and 16 are separably connected via a removable extension transmission case 19, and the lower end of the case is separably connected and fixed to a second frame 20 extending from the frame 17. The position can be changed freely.

In other words, when the grain culm to be harvested is located on one side of the machine, a so-called rotary cutting operation is performed.
The second forced weeding device 14 is set to the first working position, and the first forced weeding device side is set to the non-reaping target grain culm side, and the first forced weeding device 13 is used to separate the reaping target grain culm and the non-reaping target grain culm. The work can be carried out while smoothly dividing the grain culms, and also by smoothly dividing the grain culms to each pulling route side by the second forced weeding device 14, and non-reaping. When the target grain culm is located on both the left and right sides of the machine, the second forced weeding device 1 is used.
4 in the second working position, both forced weeding devices 1
3 and 14, the work can be carried out while smoothly dividing the grain culms to be reaped and the grain culms not to be reaped.

Note that when the second forced weeding device 14 is in the second working position, the weeding tool 21 is positioned between the first forced pulling path 8 and the second forced pulling path 9, and the first frame 18 and when the second forced weeding device 14 is in the first working position, the weeding tool 21 is repositioned laterally outward of the second forced pulling path 9 and the second frame 20 It is designed to be installed on.

To drive the second forced weeding device 14, when the second forced weeding device 14 is in the first working position, as shown in FIG. When the output shaft 23 located in the transmission case 16 is linked to the drive shaft (not shown) of the weeding device 13 and the output shaft 23 is placed in the second working position, the As shown in FIG. 3, the input shaft 22 and the output shaft 23 are interlocked and connected via a removable rotating shaft-type interlocking member 24 that is housed inside the extension transmission case 19. . That is, in either case, the configuration is such that power is transmitted from the first forced weeding device 13 to the second forced weeding device 14, and the power is transmitted from the pretreatment drive shaft 25 to both of the weeding devices 13, 14. The structure of the transmission system is simpler than that of a separate transmission system.

The above configuration can also be applied to a reaping harvester that harvests various stem culms such as rushes in addition to grain culms.

In summary, the reaping/harvesting machine according to the present invention has the first forced weeding device 13 arranged on the lateral side of the first forced pulling path 8, and the second forced weeding device 14
is provided between the first forced pulling path 8 and a second forced lifting path 9 arranged in parallel thereto, and in a position that can be freely changed laterally outward of the second forced lifting path 9. shall be.

That is, when taking the middle splitting work mode, the second forced weeding device 14 is positioned laterally outward of the second forced pulling path 9, and the first and second forced weeding devices 13,
14, it is possible to apply a forced weeding action to each of the non-reaping target stem culms located on both the left and right sides of the machine, so when taking a circular mowing operation mode, the first forced weeding device side is placed on the non-reaping target stem culm side. Since we have made it possible to apply a forced weeding action to it, no matter which type of work is used, it is possible to smoothly separate the non-reaping stem culms and the reaping stem culms, and prevent cutting, etc. due to entanglement between them. It has become possible to effectively prevent stem culm damage.

Furthermore, in the case of circular mowing work, the second forced weeding device 14 is positioned between both the pulling paths 8 and 9, so that a forced weeding action can be applied to the stem culms in both pulling paths 8 and 9. , It has become possible to smoothly divide the cut stem culms toward each pulling path side.

Moreover, since the second forced weeding device 14 is of a position-changing type, only two forced weeding devices are required, which is advantageous in terms of cost.
