Description

[Detailed description of the invention] A conventional reaping and binding machine has a guide plate provided at the rear of the cutting blade that slopes toward the rear and the discharge direction, and a belt with protrusions extending outward from the side of this guide plate. It assisted in ejecting the culm bundle released by the ejection arm of the binding device.

However, since the belt with protrusions gets in the way when stored, transported, or driven on the road, it must be folded upward. Since devices such as a holding mechanism to maintain the device and a spring and a transmission mechanism to facilitate vertical movement are required, the number of assembly and processing steps increases, resulting in high cost and troublesome operation.

The present invention is an attempt to improve the above-mentioned drawbacks, and consists of bending the middle part of a round bar to form an elongated U-shaped discharge guide rod, and attaching the discharge guide rod to the flange of a mounting bracket having a U-shaped cross section. The open end of the rod is fixed, the base side of the web of the mounting bracket is formed with a notch, and the mounting bracket is fitted from below into a support rod that protrudes laterally from the fuselage, and the notch of the flange is fitted from below. The corresponding part is rotatably supported on the support rod by a fulcrum rod in the front-rear direction, and when the discharge guide rod is rotated sideways, the inner surface of the web of the mounting metal is rotated to the support rod. It is characterized in that it comes into contact with the lower surface to assume a guiding position, and when rotated upward, the end surface of the web abuts the lower surface of the support rod and assumes a folded position in which it rises diagonally inward.

The embodiment shown in the drawings will be explained below. Reference numeral 1 denotes a machine body having wide wheels 2 and a handle 3. At the front thereof, there is a reaping device A consisting of a grain culm lifting body 4, a cutting blade 5, a narrow guide 6, etc. , door 7,
A binding device B consisting of a discharge arm 8, a knot 8', a needle, etc. is provided, and at the rear of the cutting blade 5 and the collecting culm part 9 of the binding device B, there is a guide plate that is inclined toward the rear and the discharge direction. 10 are provided.

The discharge guide rod 11 is formed into an elongated U-shape by bending the middle of a round rod, and its open end connects to one flange 1 of the mounting bracket 12, which has an upward U-shape.
2a, the tip of which is gently inclined toward the rear, and the outer part of the web 12b of the mounting bracket 12 is a notch 12c.
is fitted from below to a tubular support rod 13 protruding from the frame 1a in the culm bundle release direction, and is bored in the support rod 13 with holes bored in the portions corresponding to the notches 12c of the flanges 12a, 12a. The bolt 15 serving as a fulcrum shaft is inserted into the hole 14 in the front-rear direction, and is screwed into the fixing nut 16 on the outer surface of the flange 12a to which the discharge guide rod 11 is fixed. As shown, when the ejection guide rod 11 is laid down on its side, the inner surface of the web 12b of the mounting bracket 12 comes into contact with the lower surface of the support rod 13 as a stopper, resulting in the ejection guide position protruding outward. tighten. Also, when not in use, such as when storing, loosen the bolt 15 and move the release guide 11 to the second position.
When the mounting bracket 12 is rotated upright as shown in FIG. 3, the notch edge of the notch 12c of the mounting bracket 12 comes into contact with the outer circumferential surface of the support rod 13 as a stopper, and in this state, the bolt 15 is tightened.

In addition, in the above-mentioned embodiment, the web 1 of the mounting bracket 12
Although the outer side of 2b is cut out, the inner side may be cut out.In that case, the mounting bracket 12 is fitted onto the support rod 13 from above, and the flanges 12a, 12 are cut out.
By pivoting the part corresponding to the notch a to the support rod 13, a single mounting bracket 12 is formed as in the previous embodiment.
can be made into two types of stoppers.

As described above, the present invention forms an elongated U-shaped discharge guide rod by bending the middle part of the round bar, and fixes the open end of the discharge guide rod to the flange of a mounting bracket having a U-shaped cross section. The base side of the web of the mounting bracket is formed with a notch, and the mounting bracket is fitted from below into a support rod that protrudes laterally from the fuselage, and the portion of the flange corresponding to the notch is inserted into the support rod from the front and back. When the ejection guide rod is rotated to the side, the inner surface of the web of the mounting bracket comes into contact with the lower surface of the support rod, and it assumes the guiding position. When the web is rotated, the end surface of the web comes into contact with the lower surface of the support rod and is in a folded position in which it rises diagonally inward, thereby guiding the culm bundle bound and released by the binding device outward. When the ejection guide rod is rotated outwards, the inner surface of the web of the mounting bracket comes into contact with the lower surface of the support rod and acts as a stopper, thereby maintaining the sideways guiding posture. When the discharge guide rod is rotated upward while traveling or when traveling, the end surface of the notch in the web of the mounting bracket comes into contact with the lower surface of the support rod and becomes a stopper, thereby preventing the discharge guide rod from being moved while traveling or stored. It is possible to hold the discharge guide in a stable position without collapsing, and in the end, it is possible to use a single mounting bracket with an extremely simple structure to form a stopper that can hold the discharge guide rod in the two positions described above using its own weight. Therefore, the number of assembly and processing steps can be significantly reduced compared to the conventional method described above.

In addition, the operation of switching between the use position and the non-use position of the discharge guide rod can be performed extremely easily and quickly.
