In a combine with a steering column 3 and a driver's seat 4 provided on the lateral side in the front and rear, an assist bar 5 of a predetermined length in which at least an upper end portion 5a is bent is provided above the upper surface of the grass plate 2a at the right end. Is configured so that it can be undulated.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a combine drive assist device for a combine harvester, which can be easily seen by a boarding operator to further improve the drive controllability.

[0002]

[Prior art]

 Conventionally, a grass plate is installed obliquely on the front side of each raising case that is installed obliquely in the front part of the mowing part, and on the lateral side of the mowing part that is behind the rightmost grass plate. In a combine that is equipped with a control column and a driver's seat in the front and rear, the grass plate at the right end is located below the front side of the operator who sits in the driver's seat.

[0003]

[Problems to be solved by the device]

 Therefore, when turning counterclockwise at the beginning of mowing, it is difficult to check the height of the sward plate at the right end from the driver's seat. Because the cutting frame and cutting blade cannot be seen, the height cannot be checked.At the time of splitting work in a wetland or working in a semi-wetland that is in a collapsed state, the height reference point is completely visible. As a result, it was difficult to drive and had poor workability.

[0004]

[Means for Solving the Problems]

 The present invention has been devised to solve such a problem and enable safe and reliable driving control while looking at the right edge of the sward plate. The assist bar has a predetermined length and is bent so that it can be undulated.

[0005]

[Action]

 Therefore, if the assist bar is erected above the upper surface of the right sward board, the operator in the driver's seat looks at the upper end of the assist bar even if the tip of the sward board cannot be seen due to culms or grass. It will be possible to safely and reliably drive while manipulating the height of the section, and in that case, since the upper end of the assist bar is bent, the grain culm will be guided without damage. Also, when unnecessary, the assist bar can be laid down above the upper surface of the sward plate so that it can be stored without any hindrance.

【Example】

 1 to 5 show an embodiment of the present invention, and FIG. 1 is a side view schematically showing the front part of the combine, and the front part of the machine body in front of the threshing part B mounted on both crawlers 6 is not shown. , Each of the four tilted raising cases 1 is provided with a grass plate 2 in front of it, and a cutting section A provided with a cutting blade 7 and each conveying device 8 is provided behind it, and the raising end at the right end is provided. The right side cutting frame 10 extending from the lower side of the side cover 9 attached to the outer side of the case 1 to the front side is equipped with a grass plate 2a at the right end of the tip of the right cutting frame 10, and the cutting unit A is located behind the grass plate 2a. The lateral side is equipped with a steering column 3, a driver's seat 4 and a side column 3a in the front and rear and inward, and has the same structure as the conventional structure. Slots 11a and 11b are formed in the front and rear, respectively, and below the front slot 11a. The lower end boss 13 of the assist bar 5 which is bent to a predetermined length by bending the upper end 5a is pivotally attached to the mounting metal 12 provided on the lower end of the rear long hole 11b. A lower support boss 15b of 15a is pivotally attached, and an adjustment support rod 17 having an upper end pivotally connected to a connecting boss 16 fixed to the lower surface of the intermediate portion of the assist bar 5 is fitted into the elongated hole 11b and slid onto the support cylinder 15a. In addition to being movably fitted, locking pins can be removably fitted into the lateral holes 18 formed in the supporting rod 17 and the supporting cylinder 15a.

Therefore, as shown in FIG. 1, when the assist bar 5 is erected above the upper surface of the right sward plate 2a, even if the tip of the shunt plate 2a cannot be seen by the culm or grass, the driver's seat The operator of No. 4 can see the upper end 5a of the assist bar 5 and safely and reliably perform the driving operation while keeping the height of the cutting section A at a reasonable level. In this case, the upper end 5a of the assist bar 5 is bent. Since the grain culm is guided without being damaged, the height and inclination of the assist bar 5 can be adjusted by sliding the adjustment support rod 17 to the support cylinder 15a and locking it. When it is unnecessary, the assist bar 5 can be laid down above the upper surface of the grass plate 2a as shown in FIG. 5 so that it can be stored without trouble.

FIG. 6 and FIG. 7 show an embodiment, which has substantially the same structure as the above-mentioned embodiment as indicated by the same reference numeral, but the lower end of the assist bar 5 which is inserted into the long hole 11c formed in the grass plate 2a. It is possible to fix the parts to the mounting plate 19, and to fix the front and rear ends of the mounting plate 19 to the cutting frame 10 and the stage 20 with bolts 21a and 21b to raise the assist bar 5, and to fix the bolt 21b. When the bolt is removed and rotated around the bolt 21a, the assist bar 5 is laid down on the upper surface of the grass plate 2a and can be stored.

8 to 11 show another example, in which the cutting blade mount 22 of the double-action type cutting blade 7 in the cutting section A of the combine is mounted on the support metal 23 on the lower surface of the cutting frame 10 in the same manner as the conventional collar and bolt. Although it is configured to be attachable via a nut 24, the collar is divided into two to form an upper collar 25 and a lower collar 26 in which the lower surface 25a and the upper surface 26a have the same inclined surface, as shown in FIG. When increasing the inclination angle θ1 of the cutting blade 7 to make it a low cutting type, the upper collar 25 and the lower collar 26 can be set on the upper and lower sides of the cutting blade mounting base 22, as shown in FIG. When the cutting angle 7 of the cutting blade 7 is reduced to a low cutting type, the upper color 25 and the lower collar 26 can be set above the cutting blade mounting base 22 and can be set, as shown in FIG. If you want to high cutting formula by reducing the inclination angle θ3 of the cutting blade 7 as would be set when matching the upper collar 25 and lower collar 26 below the cutting blade mount 22.

[Effect of device]

 In this way, according to the present invention, the assist bar 5 is erected above the upper surface of the right sward board 2a, so that even if the tip of the sward board 2a cannot be seen by the culm or grass, the driver's seat 4 Since the operator can see the upper end 5a of the assist bar 5 well, the operator can safely, reliably, and easily carry out driving operation while using the upper end 5a as a guide for the height of the mowing section A. Since the upper end 5a of the assist bar 5 is bent, the grain culm can be guided without being damaged, and the assist bar 5 should be placed above the upper surface of the weeding plate 2a when unnecessary. Since it can be laid down and stored without hindrance, it has a feature that it can be suitably implemented with a simple structure.
