Then, the planted grain culm is first raised by the auxiliary raising rug 10 of the auxiliary raising device 11. After that, the main raising device 9 is taken over by the main raising lug 8 of the main raising device 9.

Although the grain culms are raised as described above, the auxiliary raising device 11 is driven by the drive means 12 independent of the drive system of the mowing device 4 and the main raising device 9. . Therefore, even when the traveling machine body is in a low speed state, the drive speed of the auxiliary raising device 11 does not become low, and a constant speed can be maintained.

In addition, the traveling body advances from the stopped state,
Even when the speed is increased to the mowing work speed, the auxiliary raising lug 10 of the auxiliary raising device 11 can be driven at a constant speed when the traveling machine body is stopped and in a certain low speed range.

[0009]

1 and 2 show a combine harvester according to an embodiment of the present invention. 4 is a reaper, which is a weeding tool 1 for weeding planted culms.
3, the main raising device 9 for raising the planted culm slaughtered by the weeding tool 13, the auxiliary raising device 11, the cutting blade 14 for cutting the culm after the raising, and the harvested culm in the center It is composed of a stock-source transporting device 3, a supply transporting device 5 for transporting the focused grain culms toward a rear threshing device 7 provided with a feed chain 6, and the like. Reference numeral 15 is an operation seat disposed laterally of the supply / conveyance device 5.

The main raising device 9 and the auxiliary raising device 1
1 will be described. In the case 9a of the main raising device 9, there is provided a main raising lug 8 which moves from the lower front side to the upper rear side and protrudes in the left-right direction to cause a planted culm. is there. In front of the main raising device 9 and on the non-acting side of the main raising lug 8, an auxiliary raising device 11 is also provided for causing grain stems. An auxiliary pulling lug 10 is provided in the case 11 a of the auxiliary pulling device 11. The auxiliary raising lug 10
Is a structure which projects from the case 11a, moves from the lower front to the upper rear, and raises the planted culm.

FIG. 3 is a transmission development view showing the main pulling device 9
It is an example of a transmission system of. In order to drive the reaping device 4, power is input by the pulley 18 to one side of the upper portion of the support frame 16 supported by the upper portion of the mission case 17. The input power is transmitted to the supply / conveyance device 5, and the other power is transmitted from the bevel gears 19 and 20 to the lower portion inside the support frame 16 via the shaft 21. The power transmitted to the lower inside of the support frame 16 is applied to the bevel gear 2
The shaft 24 is driven through the shafts 2 and 23, and the power is further transmitted through the bevel gears 25 and 26 and the frame 27 through the shaft 28 to above the mowing device 4. The power of the shaft 28 is transmitted through the bevel gears 29 and 30 to the shaft 3 in the transmission case 31a provided in the left-right direction of the reaping device 4.
1 is driven. From the shaft 31, a sprocket 32 provided on the upper part of the plurality of main raising devices 9 is driven. As a result, the plurality of main raising lugs 8 provided on the chain (not shown) wound around the sprocket 32 are provided.
Is driven.

As described above, the main raising device 9 is driven following the power input to the reaping device 4. Moreover, since the harvesting device 4 receives power from the output shaft 34 of the hydraulic continuously variable transmission 33 for driving the traveling device 1, the drive speed changes in association with the traveling speed, and therefore the main pulling The drive speed of the device 9 also changes in association with the traveling speed. However, as shown in FIG. 2, the auxiliary pulling device 11 is driven independently by the driving means 12, so that it is driven regardless of the traveling speed. The drive means 12 includes a central processing unit 35.
Based on information from the vehicle speed sensor 36 connected to the input side of the CPU (hereinafter referred to as the CPU), the drive means 12 (in this embodiment, the hydraulic motor is used, but may be an electric motor).
In short, any device that can independently drive the auxiliary pulling device 11 may be changed in speed and driven. The driving means 12 may be driven at a constant speed.

Next, FIGS. 4 and 5 will be described. As shown in the figure, the driving speed of the main pulling device 9 shown by the solid line is also changed in association with the acceleration and deceleration of the vehicle speed.
FIG. 4 is a view when the grain culm is not lying down, and FIG.
Is when the culm is lying. When the grain stalk is lodged, unless the grain stalk is caused quickly, the grain stalk can not follow the forward speed of the traveling machine, and the tip of the grain stalk is caught by the cutting device 4, so the driving speed Is making faster. Of course, the contents of the related control in FIGS. 4 and 5 are stored in the CPU 35 in advance.

The dotted line shows the driving speed of the auxiliary raising device 11. In this way, the auxiliary pulling device 11 is driven by the driving means 12 at a constant driving speed even in a low speed region of the vehicle speed or in a stopped state. Of course, when the reaping lever 37 installed in the operator's seat 15 for driving or stopping the reaping device 4 is turned off,
When U35 detects, the drive of the drive means 12 is stopped.

In a combine equipped with the above-mentioned mechanism, when the machine is advanced and the work is started, the grain culm is triggered by the auxiliary raising device 11 and then taken over by the main raising device 9. Raised and cut with the cutting blade 14. The presence of the auxiliary raising device 11 exerts its power particularly in the raising action of the lying grain culm. The grain culm cut by the cutting blade 14 is handed over from the stock-source transfer device 3 to the supply transfer device 5, and further to the rear threshing device 7
It is conveyed to the feed chain 6 of. The grain culm taken over by the feed chain 6 is threshed while being conveyed backward.

When performing such a mowing operation, the combine is sometimes run at a low speed in order to improve the condition of the field and threshing selection. When the vehicle travels at a low speed, as described above, the drive speed of the main raising device 9 also becomes a low speed drive. However, since the auxiliary pulling device 11 is driven by the independent drive means 12, it is possible to obtain a constant drive speed even when the vehicle speed is low. Therefore, even when the vehicle speed is low, the raising action of the fallen grain culms is improved. Further, when the combine moves forward from the stopped state and starts the mowing operation, the auxiliary raising device 11 is driven by the drive means 12 in advance, so that the raising action of the fallen grain culms is improved.

After that, when the combine is accelerated to a high speed state, the auxiliary raising device 9 is driven at the same driving speed as the main raising device 9, so that it is possible to prevent the disturbance of the transportation of the grain stem due to the difference in the raising speed. Next, FIG. 6 will be described. A grain culm guide guide 38 is provided on the upper part of the auxiliary raising device 11. The mounting method of the grain culm guide guide 38 is, as shown in FIG. 6, the outer peripheral portion of the case 11a of the auxiliary raising device 11 in a side view (b), and a front view (a).
In (1), it is configured such that it is fixed to the side through which the grain culm passes, that is, the side where the main raising device 9 is provided, by welding or the like (may be detachable with bolts or the like). Therefore, first, the starting portion 38a on the lower side starts from the lower rear portion of the case 11a, passes through the lowermost portion of the case 11a, and is further installed rearward and upper along the outer peripheral surface. Since the starting end portion 38a is the lower rear side of the auxiliary raising device 11, as the combine advances,
When the grain culms come into contact with the grain culm guide guide 38, they smoothly abut. Therefore, shedding and damage to the grain stem can be prevented, and the grain stem can be guided without disturbing the posture of the grain stem.

In the upper rear part of the case 11a, FIG.
As shown in (a), in order to mainly raise the culm and guide it toward the device 9, the culm is inclined to the left and right by a constant angle A. As a result, the grain culms are guided smoothly. Further, as shown in FIG. 6B, in a side view, the auxiliary raising device overlaps with the upper part 39 of the raising operation region of the auxiliary lug 10 and is inclined forward and upward, with respect to the auxiliary raising device 11. To set a constant angle B. Therefore, when the auxiliary raising lug 10 is operating, the grain culm is moved upward and upward, that is, separated from the auxiliary raising device 11, so that the tip portion does not get caught in the auxiliary raising device 11 and the main raising device is pulled. You will be guided to 9.

Next, FIG. 7 will be described. (A) is a front view of the mowing device 4, (b) is a side view, and (c) is an enlarged view of the corner portion 40. The embodiment of FIG. 7 is a case where the auxiliary raising device 11 described in FIGS. 1 to 6 is not provided. Since the auxiliary raising device 11 is not provided, the dead space 41 is formed on the non-acting side of the main raising device 9 of the main raising lug 8.
Becomes Using the upper part of the dead space 41, a grain culm guide guide 42 is installed. The installation method is the support stay 4
2a is fixed to a transmission case 31a which is provided above and behind the main raising device 9 in the left-right direction, passes through the dead space 41, and is projected in front of the main raising device 9.

A grain culm guide guide 42 is provided from the end of the support stay 42a. The grain culm guide guide 42 bypasses the front of the main raising device 9 and extends in the direction of action of the main raising lug 8. In addition, the main raising device 9 and the transmission case 31a are installed.
The corners 40 formed by and are raised upward so that the tips of the grain culms do not come into contact with each other. Further, the rear of the grain culm guide guide 42 forms a constant angle C with respect to the vertical line 43 in the non-acting direction of the main raising lug 8.

The starting end position 42b at the constant angle C is near the point where the grain stems are mainly raised and passed through the device 9. This is because if the grain culm guide guide 42 is kept in contact with the grain culm even after the grain culm has passed through the main raising device 9 and the grain culm is subjected to an unreasonable force, the transport posture is disturbed, and the stock is transported. This is because the grain culm is not smoothly transferred when the device 3 is handed over to the supply / conveyance device 5.

As described above, the grain culm guide guide 42 is constructed so that the tip of the grain culm does not come into contact with the corner portion 40 between the main raising device 9 and the transmission case 31a. Passing the main raising device 9 smoothly,
It can prevent shedding.

[0023]

As described above, according to the present invention, since the auxiliary pulling device 11 is driven by the independent driving means 12, a constant driving speed can be obtained even when the vehicle speed is low. Therefore, even when the vehicle speed is low, the raising action of the lodging grain culm is improved, and also when the traveling machine body advances from the stopped state to start the mowing work,
When the auxiliary raising device 11 is driven by the driving means 12,
The action of raising the fallen grain culms is improved.
