DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bound grain stalk releasing device of a cutting and binding machine, and in which a focusing device for collecting bound grain stalks bound by the binding device is provided on one side of the machine body. It belongs to the technical field of releasing bundled culm backward.

[0002]

2. Description of the Related Art Conventionally, in a mowing operation of a mowing and tying machine, tied grain culms bound by a tying device have been released one by one when releasing to a soil surface. In this case, it is difficult to collect the released bundles in the post-operation, so the released bundles are collected by a focusing device until a predetermined number of bundles are reached, and the base end of the focused grain culm in the focusing device is subjected to a stock receiving. While receiving and supporting the plate, the spike side is received in a rearwardly inclined posture by the spike receiving plate, and the concentrated grain culm is released backward by retreating upward from the spike receiving plate. At the time of release, when the spike receiving plate is rotated and retracted upward, the release delay portion of the collected grain culm on the spike tip side is caught by the lower end of the spike receiving plate, and the caught spike side is attached to the spike receiving plate. Of the collected stalks collected at the return of rotation There has been a drawback that the attitude of focusing culms after the release dragged along with the forward movement of the aircraft is not settled collapsed.

Therefore, according to the present invention, a relief portion is provided at a lower end portion of a pan receiving plate of a bunching device, the bunching portion being bent to a release side in a range where the spike tip side of the released bundled grain stalk is not caught.

[0004]

According to the present invention, a binding device 1 is provided.
Base plate 2 for receiving and supporting the base end of the bundled grain culm obtained by collecting a predetermined number of bundles of the united grain culm, and the spike portion of the bundled grain culm located above the base plate 2 Device 4 having a flat-shaped ear receiving plate 3 that receives the side in a backward inclined posture and discharges the collected grain stalks rearward by rotating and retracting upward.
In the cutting and binding machine provided on the outside of the binding device 1, when the spike receiving plate 3 is released by the upward rotation, the lower end portion of the spike receiving plate 3 has a tip-side release delay portion of the concentrated grain culm. And a release portion 3a for preventing the catch of the stalks is provided.

[0005]

According to the above-mentioned structure, during the harvesting operation of the tying and binding machine, the bundle of the bunching unit 4 in which the bound grain stalks bound by the tying device 1 are arranged on the outside of the body adjacent to the discharge side of the tying device 1. The original receiving plate 2 receives and supports the base end portion of the collected cereals collected in a predetermined number of bundles, and supports the spike side of the supported collected cereals with, for example, the flat plate portion of the spike receiving plate 3 and the left and right. The side wall portions on both sides receive the rearwardly inclined posture, and a rotation shaft provided at an appropriate position of the side wall portion on the body side of the ear portion receiving plate 3 is rotated by a rotation base provided on one side of the body. Due to the retreat of the upper part receiving plate 3 to the upper side, the collected cereal culm falls backward from the ear part side and is released to the soil surface with the advance of the machine body. At the time of this release, when the spike receiving plate 3 is pivoted and retracted upward, the release delay portion of the collected grain culm on the spike end side is more likely to be caught on the lower end portion of the spike receiving plate 3. By providing the escape part 3a bent to the release side at the lower end of the ear part receiving plate 3, the tip side of the collected cereal culm is caught by the lower end part of the ear part receiving plate 3 and the release is hindered. There is no.

[0006]

As described above, a predetermined number of bundles of the bound grain culm bound by the binding device 1 of the cutting and binding machine are collected on the stock base receiving plate 2 of the binding device 4 located outside the binding device 1. Receiving and supporting the root end of the collected grain culm, the spike side of the collected grain culm is received by the spike receiving plate 3 in a backward inclined posture, and the spike receiving plate 3 is rotated upward. By retreating, the collected cereal culm is released to the soil surface while tilting the ear part side backward, and at the time of this release, the escape part 3a is provided at the lower end of the ear part receiving plate 3, so that the bunching is performed as in the past. When the release delay portion on the tip side of the cereal stem is caught by the flat plate edge without the relief portion 3a at the lower end of the ear part receiving plate 3, when the ear part receiving plate 3 returns to rotation, the tip side is brought back and the release is inhibited. Dragging and releasing part of the collected cereal stems collected by the forward movement of the fuselage No disadvantage that the posture of the focusing culms are settled not collapsed, and the focusing culms beautifully collectively for every predetermined number of bundles can be released to the soil surface, the rear work is facilitated.

Guide to 4.

When the grain stalk guided to the binding passage 14 is compressed by the packer 13b and the pressure receiving projection 13c reaches a set pressure, a binding string is wound around the compressed grain stalk by the needle 13a, and the wound string is wound. Is knotted by the string knot portion 12a, and when the knot is completed, the discharge arm 12b sends the knot to the focusing device 4 adjacent to the outside of the binding device 1 for collection.

The root end of the united grain culm collected by the collecting device 4 is received and supported by the bottom plate 2a of the base plate 2, and the culm part and the spike are received by the upper and lower guide rods 2b. It is guided to the ear part receiving plate 3, and the bottom end 2a supports the base end of the stock and the ear part receiving plate 3 receives the ear part to collect in a backward inclined posture. When it is detected that the collected bundled culm has reached a predetermined number of bundles set in advance, a clutch or the like is operated by an interlocking mechanism of a rotating case 28 provided on the body 5 side to rotate the rotating shaft 27. Is rotated, and the spike receiving plate 3 is rotated upward in the direction of escaping from the spike side of the collected grain stalk and retracts, whereby the collected grain stalk loses support and falls backward from the spike side, The air is released to the soil surface as the airframe 5 advances.

As shown in FIG. 3, when the lower end portion of the spike receiving plate 3 which rotates upward is a normal flat plate edge, the release delay portion on the spike tip side is easily caught as shown in FIG. However, as shown in FIG. 4, the lower end of the flat plate edge of the ear receiving plate 3 is bent rearward to form the escape portion 3a, so that the catch can be avoided. Since the release delay portion is not hooked and taken back when the rotation return of the body 3 is performed, a part of the collected cereal culm collected by the forward movement of the machine body 5 is dragged, and the posture of the converged cereal culm after the release is broken. Without being bundled, it can be collected into a predetermined number of bundles and released to the soil surface.

Further, in the convergence device 4 for discharging the bundled grain culm obtained by collecting the bundled bundle of the predetermined number of bundles to the soil surface as described above, the bunching device 4 of the bundler 4 is received in the rearwardly inclined posture. When the number of bundled grain culms increases, the spike side of the increased bundled grain culm is held by the flat plate portion 3b of the ear portion receiving plate 3 with only the right and left ends restricted by the side wall portions 3c. While being done, the ear part gradually enters and gets entangled,
There was a problem that the posture after release on the soil surface collapsed and it did not gather.

For this reason, as shown in FIG.
By controlling the left and right movement of the collected grain culm collected on the flat plate portion 3b, the protrusions 3d for regulating the movement to the left and right are provided, thereby suppressing the disturbance due to the entanglement on the spike portion side. In addition, the bundled grain culms can be collected neatly for each predetermined number of bundles and released to the soil surface. Note that a plurality of the regulating portions 3d may be provided.

An appropriate space is usually provided between the terminal end of the guide surface of the guide cover 15 of the body 5 and the left side wall 3c of the spike receiving plate 3 of the focusing device 4. In general, there is a problem that the culm part of the united grain culm sent from the tying device 1 to the tying device 4 is sandwiched in the interval a so that the tying cannot be performed smoothly. For this reason, as shown in FIG. 7, by providing an interval cover 29 having an appropriate length in the vertical direction to prevent the culm part of the united grain culm from being pinched, as shown in FIG. The culm is the interval a
Focusing can be performed smoothly without being sandwiched between the two.
