Description

[Detailed description of the device]

[0001]

[Industrial application] The present invention binds a stalk culm raising device in a rearwardly tilted posture causing a planting stalk and a stalk culm to be bundled and discharged toward the outside of one side of the machine. The present invention relates to a walk-behind harvesting and binding machine having a binding device and a control section arranged at the rear of the machine body.

[0002]

2. Description of the Related Art In the above-mentioned walk-behind cutting and binding machine, conventionally, as disclosed in, for example, Japanese Utility Model Laid-Open No. Sho 63-9831, the upper side of the stem and culm raising device is open,
There has been a structure in which a mechanism for adjusting the position of the standing guide in the raising device is provided so that the higher the traveling speed becomes, the lower the raising end position is lowered.

[0003]

SUMMARY OF THE INVENTION The above-mentioned conventional structure is capable of performing a high-speed pulling operation by the pulling device when, for example, the stem culms are wet with rainwater or morning dew, or when the stem culms are easy to shatter. As a result, water and grains may scatter toward the control part, so when the traveling speed is high, the action height of the raising and locking pawl is set to a low level to cause such problems. Is to prevent.

However, even in the above-mentioned conventional structure, the effect of preventing scattering is not sufficient, and there is still room for improvement. Moreover, according to the above structure, the raising path is shortened, so that the raising function is deteriorated.

An object of the present invention is to solve the above problems.

[0006]

According to a characteristic configuration of the present invention, in the walk-type cutting and bundling machine described at the beginning, a stem-culm raising device is located on the opposite side of the raising device from the direction in which the bundle-shaped stems are discharged. A scattering prevention cover is provided above the end portion of the raising path, and is located in a state of intersecting the extension line of the raising path to prevent the scattered matter from the stem culm raising device from falling onto the control section. There is a point.

[0007]

Operation: Even when performing mowing work while traveling at high speed on the machine body, due to the high-speed operation of the raising device, water and grains are scattered backward from the end of the raising route, but The shatterproof cover, which is located in a state that intersects with the road, blocks the shattering path from the trailing end of the raised path to the rear control section, preventing further scattering to the rear, that is, to the control section. Therefore, it is possible to effectively prevent the moisture and the grains from falling on the control section, and further, the length of the raising path can be set to a required length, and the raising function does not deteriorate.

[0008]

[Effects of the Invention] Therefore, the reaping work can be smoothly performed, and it is possible to effectively prevent water droplets and grains from falling on the operator, and the work can be performed comfortably.

[0009]

Embodiments will be described below with reference to the drawings. FIG.
Fig. 2 shows a two-row cutting type walk-behind binding machine. This reaper binding machine pivotally supports a pair of left and right wheels 1, and
In front of the wheel 1, a pair of left and right stem culm raising devices 2a, 2b in a rearwardly tilted posture for raising planted stems, a clipper-type cutting device 3 for cutting the roots of the raised stems, and a mowing And a binding device 4 for binding the stems and discharging them toward the lateral one side of the machine body. An engine 5 is mounted behind the wheel 1 and a steering handle 6 is extended to extend the machine body control section. 7 is provided.

A roll-shaped preliminary winding string 8 for binding is stored near the base end of the steering handle 6. The preliminary winding cord 8 is formed by winding a cord in a cylindrical shape, and is accommodated and supported by a support frame fixed to a frame 9. That is, as shown in FIG. 2, a front view gate-shaped support member 10 is connected and fixed to the frame 9, and a pair of left and right columns 11 and 12 is erected from both left and right sides of the support member 10, and a flat surface is provided on the upper part thereof. A rectangular frame member 13 is fixed, and the preliminary winding string 8 is housed and supported by the frame member 13 and the supporting member 10. Then, one of the columns 11 is extended above the frame member 13, and this extended portion is also used as a support portion of the used winding cord outer bag 14.

As shown in FIG. 1, the respective raising devices 2 are
The a and 2b are configured to raise the planting stem culms of the row to be mowed guided by the three grass bodies 15 to the standing posture by the plurality of locking claws 16, and the raising devices 2a and 2b. A wide guide plate 17 for receiving and supporting the raised stem culm is arranged at the rear of the, and the guide plate 17 has two upper and lower stages for laterally feeding and locking the cut stalks toward the lateral side of the machine body. Endless belts 18 and 19 with locking projections are provided.

The binding device 4 includes endless belts 18, 19
It is configured to bind the cut stalks that have been laterally fed by and to discharge them to the outside of the fuselage.

Each of the raising devices 2a and 2b raises the locking claw 16 at a predetermined pitch on the endless chain 22 wound inside the raising case 20 over the upper and lower wheels 21a and 21b. An erection guide 23, which is pivotally supported so as to be swingable, and which guides each of the elevating and locking claws 16 to erect is provided in the elevating action path. Further, the raising device 2a located on the discharge direction side of the bundled stem culm raises the standing guide path of the locking claw 16 and extends to a position above the case 20,
The above-mentioned lateral feed operation can be smoothly performed.

Then, the pair of raising devices 2a, 2b.
The raising device 2b, which is located on the side opposite to the direction of discharging the bundled stems, is configured so that the standing guide path of the locking claw 16 ends near the end of the straight raising portion, and as described above. It is designed not to hinder the lateral feeding operation and to prevent the continuous rotation due to the catch of the stems. In addition, above the end of the raising path of the raising device 2b located on the side opposite to the direction of release of the bundled culm, the stem culm raising is located in a state of intersecting the extension line of the raising route. A scattering prevention cover 24 is provided to prevent the scattered matter from falling onto the control section 7 by blocking the scattering path from the device 2b to the rear control section 7. The anti-scattering cover 24 is erected and connected to a midway position on the upper surface side of the raising case 20 and an upper portion of the guide plate 17, and is provided on the upper side of the locking claw 16 at the end of the raising path of the raising device 2b. Even if water droplets or grains are scattered due to the arc-shaped rotation locus of the wheel body 21a, it is possible to effectively prevent those scattered objects from landing on the operator.
