Further, the upper portion of the vertical transmission case 71 has a lower front end and a sled frame 65.
And is stably fixed to the upper part of the raising case 61 fixed to the upper case.

In the illustrated handle 2, the grip 20 is formed in a loop shape, and both front ends of the handle bars 21, 21 can be attached to and detached from the sled frame 65 of the cutting and binding device 5 via an attachment portion 65a. It is fixed to. The middle portions of the handle bars 21 and 21 are connected by a connecting bar 22 (FIG. 4), and a mounting bracket 80 (FIG. 3) provided on the left handle bar 21 is connected to a transmission case 60 via a wheel adjusting mechanism 8 described later.
To form a rigid frame. Further, various operating levers and operating tools such as an engine throttle lever are attached to the grip portion 20 as in the related art.

The frame structure 7 includes a transmission cylinder 70, a vertical transmission case 71 connected to the transmission cylinder 70 in a T-shape, and a handlebar 21 of the handlebar 2 as shown in FIG. By forming a rigid frame that does not cause frame collapse or the like by connecting them, a frame structure can be formed without increasing the strength and weight of each mounting portion.

That is, the transmission cylinder 70 of the frame structure 7 connects the vertical transmission case 71, which is firmly supported by the mowing part 5a in the substantially horizontal position in the vertical direction, and the transmission 6, which is stably supported by the transmission case 60, The transmission shaft 70a is provided inside the transmission cylinder 70 to form a downwardly L-shaped frame member having a long side and a short side.

The handle 2 is composed of left and right handle rods 2.
1 is bent downward, and its lower end is formed at the rear of the sled frame 65 near the lower portion of the vertical transmission case 71.
5a, and a mounting piece 21a projecting forward is fastened to the cutting frame 6f and the counter case 66 at the upper portion thereof. Also, by being connected to a mounting piece 70b provided on the transmission cylinder 70 by a mounting piece 22a (FIG. 3) provided on a connecting rod 22 at an intermediate portion of the handle rod 21, it is integrally formed in a downward L-shape. The handlebar 21 is connected to the vertical transmission case 71 and the transmission cylinder 70 in a staggered manner, and the vertical transmission case 71, the transmission cylinder 70, and the handlebar 21 have a rigid frame having a triangular rigidity in a side view. The structure can be made.

The attachment piece 21 of the right handlebar 21 is provided.
As shown in FIG. 4, a is connected to the notter case 6n to improve the strength. As shown in FIG. 3, the handle 2 supports a middle portion of the handle rod 21 via the transmission case 60 and the wheel adjusting mechanism 8 to change the distance between the handle 2 and the wheel 3a to change the wheel 3a. The up-and-down adjustment is made possible, so that the mowing tying machine 1 can appropriately cope with mowing tying work in both dry and wet fields.

The wheel adjusting mechanism 8 includes a mounting bracket 80 suspended from the handlebar 21 and a mounting bracket 82 with a long hole 81 projecting upward from the transmission case 60.
By fastening with an attachment shaft 84 having an operation lever 83, the transmission case 60 and the output shaft portion 60a of the transmission 6 are supported rotatably within the range of the elongated hole 81 around the output shaft portion 60a.

In such a mowing and binding machine 1, as shown in FIG.
1 is formed so that the interval between its mounting portions is substantially the same as the width of the left and right sled frames 65, and the interval behind this is gradually expanded in a fan shape, so that the engine 6
a, the transmission 6, and a transmission case 60 that supports the wheels 3a are arranged within the width of the handlebar 2 toward the uncut land side. Therefore, the handle rod 21 of the handle 2 on the transmission case 60 side is also configured to act as a narrow guide member for guiding the planted culm on the uncut side.

With the above construction, the binding portion 5b as a heavy object and the engine 6a are arranged on the right and left sides of the body, and the raising case 61 and the transmission cylinder 70, and the transmission 6 and the transmission case 60 are arranged on the left side. This allows the left and right aircraft balance to be well balanced and enables stable running.

During the cutting and binding operation, the planted cereal culm (left side) on the uncut side is guided by weeding on the left outer side of the raising case 61, and is further guided rearward by the base of the left handlebar 21 while being rearward guided. , And can be pushed to the uncut side so as to move away from the body by the handle rod 21 which is inclined while expanding.

Therefore, the planted grain culm can move rearward without contacting the transmission case 60 and the transmission 6 located inside the handle 2, and the planted grain culm can be caught on the machine body or shed. It is possible to satisfactorily carry out the cutting and binding work without losing.

Reference numeral 9 denotes a guide plate provided so as to guide and guide the harvested grain culm from above the cutting blade 62 of the cutting unit 5a toward the binding unit 5b.
And a cradle rest provided above the transmission cylinder 70 at the rear.

The mowing and tying machine 1 constructed as described above first adjusts the wheel adjusting mechanism 8 to position the height of the wheel 3a in accordance with the condition of the dry and wet fields in the field, and then runs the machine.
While cutting the planted cereal culm by the cutting unit 5a, the unit is bound to a predetermined weight by the binding unit 5b and released to the outside of the right side machine, so that a series of cutting and binding work can be performed smoothly.

When the cutting and binding work is performed, when the wheel 3a falls into a groove, sinks in a wetland, or crosses a ridge, the operator lifts or pushes down the handle 2 with strong force. However, the mowing and binding machine 1 connects a vertical transmission case 71 and a transmission cylinder 70 for connecting and transmitting the mowing portion 5a and the binding portion 5b of the mowing and binding device 5 in a downward L-shape. A lower portion of the transmission tube 70 is connected to a lower portion of the transmission tube 70, and the vertical transmission case 71, the transmission tube 70, and the handle 2 constitute a triangular frame structure in a side view.

Therefore, with the framework structure 7, the mowing and binding device 5, the engine 6a and the transmission 6 can be stably supported in a well-balanced manner before and after the machine body centering on the wheels 3a. The force to be applied can be distributed to the triangular frame structure 7 as described above without significantly bending the handle 2, and the deformation of the frame structure 7 can be prevented from the above-mentioned situation of the traveling body 3 while preventing deformation of the frame structure 7. You can easily escape.

Further, by forming the handle 2 in a loop shape and connecting the intermediate portion of the handle rod 21 of the handle 2 to the transmission cylinder 70, the force is not concentrated on a specific local portion of the mounting portion. There is an advantage that the framework structure can be simplified by simple means such as simple connection using the respective structural members of the body, thereby providing a light weight cutting and binding machine 1.

Also, at the time of cutting and bundling work, the planted grain culm on the uncut side is tilted and guided toward the side by the handle 2 which gradually expands to the outside of the fuselage toward the rear, so that the planting culm is guided. It is possible to satisfactorily carry out the cutting and binding work while preventing the culm from being caught or falling off. As described above, since the handle 2 also functions as a narrow guide, there is an advantage that the structure of the body can be simplified.

[0029]

As described above, in the handle structure of the mowing tying machine according to the present invention, the engine 6a, the transmission 6, and the wheels 3a are located below the handle 2 from the side of the cut ground in plan view. Is disposed within the width of the handle 2 so as to face the uncut land side, so that the handle rod 21 of the handle 2 on the transmission case 60 side is connected to the planted grain culm on the uncut land side. Is also used as a narrow guide member for inducing weeding. Therefore, the handle 2 itself performs a narrow guide function to incline and guide the planted grain culm on the uncut side to the side, so that the structure of the narrow guide can be simplified and the planted grain culm can be simplified. The cutting and bundling work can be performed satisfactorily while preventing catching, shedding, and the like.
