Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a raising device for raising planted culms, a cutting device at a lower front part for cutting the root end of the raised planted culms, A rear transport device that holds and transports the harvested grain culm backward while standing upright, a rear upper reaping device that cuts off the root side of the transporting grain culm in the upright posture, and the harvested grain culm tip side part is the middle part of the cutting width. The present invention relates to a pretreatment head structure of a combine equipped with a merging device for laterally feeding and merging.

[Prior Art] The combiner pretreatment head unit, which has been described above, is arranged from the lower part of the rear end frame (12) to the merging device (6) as shown in FIG.
A lower support member (13) linearly extending forward through the lower part of the front part, and a front lower mowing device (5) attached to the front end of the lower support member (13) and a vertical support member (3) for supporting the rear transport device (3). The lower end of 17) was connected to the front end portion of the lower support member (13).

In other words, the rear upper mowing device (4) has a lower support member (1
It was located at a position away from the front of 3) above.

[Problems to be solved by the device]

The harvested grain culm cut at the root end by the cutting device at the lower front part is conveyed by the rear transportation device, and this time the cutting end at the root end is cut off by the cutting device at the rear upper part, so that the grain culm tip, which is the graining part. Part is sent to the threshing device, and the cut root end is dropped and discharged from the space below the mowing device at the rear upper stage between the vertical support member and the merging device to the ground. .

However, in the prior art, since the lower support member is lying below the space, that is, at a height position near the root end of the cut grain culm, the cut root end is discharged to the ground. The posture is changed on the way to a horizontal posture, and it is easy to accumulate on the lower support member or in a state of straddling the lower support member and the supporting portion of the lower cutting device of the front part, and when that happens, the grain culm by the rear transport device is There is a risk of disturbing the transportation posture, or the end of the base of the stock may become clogged in the space and discharge may become impossible. In particular, in wetlands, the root end portion cut off due to the adhesion of mud to the lower support member was more likely to be deposited and deposited on the lower support member to cause the above problems.

The present invention has an object to eliminate the above-mentioned inconveniences by devising the structure of the pre-mowing treatment head part and to smoothly discharge the cut root end part to the ground without clogging. is there.

[Means for Solving the Problems]

Therefore, in the present invention, in the structure of the pretreatment head of the combine described at the beginning, the harvesting device at the lower front part is attached to the lower end of the vertical support member that supports the rear transport device, and the rear device is arranged at the rear of the merging device. A lower support member in a state of circumventing the lower part of the joining device is extended forward from the lower part of the end frame, and a front end portion of the lower support member is
While standing up from the lower side of the merging device until it comes close to the lower part of the mowing device on the rear upper stage arranged between the vertical support member and the merging device, the front end of this rising part is located on the front lower stage. It is characterized in that it is connected and fixed to a vertical member standing upright from the reaping device.

[Action]

In other words, since the root end of the stock that is cut by the upper cutting blade is in the standing posture, the rising portion of the lower support member is at a height position corresponding to the upper end of the stock end after cutting. Therefore, immediately after being cut and starting to fall, the rising portion will be present above or above the falling stock root end portion, and therefore the space portion is opened downward, After that, no matter how the posture changes during the fall of the root end of the stump, it is possible to prevent the stump from accumulating and clogging due to the lower support member as in the past. Become.

Further, since the rising portion is arranged in the front-rear direction, even if it exists in the transfer route at the base end of the stock, the transfer direction is the front-rear direction. It will never happen.

Since the front end of the rising portion is connected and fixed to the lower reaping device via the vertical member as in the conventional case, the function as the support member, that is, the frame is not impaired.

[Effect of device]

Therefore, by devising the shape of the lower support member, the cut base end portion is blocked without adversely affecting the frame function of the pretreatment head portion and the transportation state of the culm by the rear transportation device. Could be discharged smoothly.

〔Example〕

Hereinafter, an example of applying the present invention to an axial flow combine will be described with reference to the drawings.

As shown in FIG. 3, a vertical feed divider type weeding device (1) for weeding planted culms, a raising device (2) for raising slaughtered planted culms, and a raised planting plant. The lower cutting machine (5) for cutting the root end of the standing grain culm, and the cutting grain culm to the rear while standing upright by the ears-locking transfer device (3A) and the root holding device (3B). A rear transport device (3) for transporting, a rear upper mowing device (4) for cutting off the plant base side of the transport grain culm in an upright position, and a harvested grain culm tip side portion are laterally fed and merged to the middle part of the cutting width. A pretreatment head part (7) equipped with an auger type confluence device (6) and a feeding and conveying device (9) for conveying the grain-and-cusp tip side part inherited from the confluence device (6) toward the threshing device (8). ) Is installed inside the feed case (10),
The hydraulic cylinder (11) is attached to the traveling machine body (B) via the base end of (0) so as to be capable of swinging up and down, and constitutes an axial-flow combine combine with 6 cuttings.

Next, the pretreatment head section (7) will be described.

As shown in FIGS. 1 and 2, the feed case (1
0) from the lower end and the upper end of the rear end frame (12) of the pretreatment head part (7) having a connecting part with the pretreatment head part (7) while detouring below and above the joining device (6), respectively.
A transmission case (1) in which a lower support member (13) and an upper support member (14) for supporting the vehicle are extended forward, and a lateral transmission shaft (not shown) is installed at the front end of the upper support member (14).
5) is attached, and a branch transmission case (16) for branching and transmitting the power from the lateral transmission shaft to the rear transfer device (3) is attached downward from the transmission case (15), and A vertical support member (17) supporting the transfer device (3) is erected and connected between the cutting blade support member (19) to which the front end of the lower support member (13) is connected and the branch transmission case (16). A vertical frame body having a loop shape is formed in a side view.

A plurality of the vertical frame members are arranged side by side in the left-right direction by the cutting blade support member (19) horizontally fixed to the tip of the lower support member (13), the transmission case (15) and the rear end frame (12). The frame (F) of the pre-processing head unit (7) is constructed.
