Description

[Detailed description of the invention] Conventionally, in a harvesting machine equipped with a binding device, a bundle carrier for carrying out released bundles is provided, and a shaft is attached to a support frame to convert the bundle carrier into a bundle carrying position and a storing position. Although it is already known to support the bundle, the means for holding the bundle conveyor in the bundle delivery position or the storage position is complicated, and there are drawbacks such as not only straw being easily caught in the bundle but also high cost.

The present invention improves the above-mentioned drawbacks, and provides a bundle conveyor for a harvester that is strong, lightweight, inexpensive, and prevents damage even if it collides with obstacles. In a harvesting machine, the base of a bundle carrier is pivotally supported on the bundle release side of a bundling device so as to be pivotable between a bundle conveying position and a folded storage position. The supporting frame is constructed by bending both sides of the plate body toward the bundle conveying body, and the bent portions serve as receiving pieces, and the bundle conveying body is placed at the base of the bundle conveying body in the bundle transporting position or in the storage position. Provided with one stopper that comes into contact with the inside of one of the receiving pieces when the position is changed to change the position to the bundle delivery position or storage position,
A toggle spring is provided between the bundle transporting body and the support frame to maintain the changed attitude beyond the pivot support when the bundle transporting body changes its attitude, and the toggle spring is rotated rearward near the base of the bundle transporting body. A backstop for preventing the bundle from moving is provided, and the backstop is configured with a small protrusion that can cause the receiving piece to pass through the related member due to distortion when an excessive pressing force is applied to the bundle conveying body from the front. It is something.

The embodiment shown in the drawings will be explained below.1
is a cutting blade installed at the front of the machine, and on both sides in front of it are grain culm triggering bodies 3, 3 having cutting bodies 2, 2.
An intermediate grass body 5 having a guide rod 4 at the rear is disposed between them, wheels 6 are pivotally supported on both sides of the intermediate part of the body, and an engine 7 and a handle 8 are mounted at the rear. is provided.

Reference numeral 9 denotes a guide plate erected in a rearwardly inclined position immediately after the cutting blade 1, and has two upper and lower slits 10, 10.
Protrusions 11b attached to the transverse belts 11a protrude from each of them, and a known binding device 13 equipped with a packer, a needle, a knot, a discharge arm 12, etc. is mounted on the back of one of the grain culm pulling bodies 3. It is provided.

The support frame 14 on which the upper transverse conveying belt 11a is stretched is attached to the upper part of a support column 11c set upright on the machine frame. Rotatably supported,
The horizontal conveying belt 11a is wound around the V-pulley 17 fixed to the upper part of the vertical shaft 16, and the carry-out frame 19 of the bundle conveyor 18 is attached to the lower part of the shaft bearing cylinder 15.
A holding cylinder 20 welded to the base of the top cover 19a is loosely fitted, and the upper end of this holding cylinder 20 and the support frame 1
A slight gap is provided between the lower surface of 4 and the lower surface of 4.

In addition, a V
A V fixed to the pulley 21 and the lower part of the vertical shaft 16
A delivery belt 23 with projections is stretched over the pulley 22.

Thus, the support frame 14 includes two iron plates 14a,
14b are overlapped and fixed, and the rear edge of the upper iron plate 14a is bent downward to form a receiving piece 24, and the front edge thereof is bent diagonally forward and downward to form a guide plate. 9 is installed, and the lower iron plate 1
The front edge of 4b is bent downward to form a receiving piece 25.

Furthermore, a stopper 26 that abuts the front surface of the rear receiving piece 24 in the bundle carrying position and a low back stopper 27 that engages with the rear surface of the receiving piece 24 are provided in close proximity to the rear portion of the base end side of the carrying-out frame 19. be.

Furthermore, a toggle spring 31 is stretched between a receiving plate 29 which is vertically installed near the V-pulley 22 of the carry-out frame 19 and has a scraper 28 attached thereto, and a latch 30 which is vertically installed on the support frame 14 (iron plate 14b). be.

In the above-mentioned apparatus, when performing the cutting and tying work, the bundle delivery body 18 is extended to the side of the machine body as shown in FIGS. 3 and 4. At this time, the stopper 26 comes into contact with the rear receiving piece 24 as shown in FIG. 6, and the toggle spring 31 is displaced above the vertical axis 16 as shown by the dashed line in FIG. A constant carrying-out posture is maintained, and even if a force greater than the tension of the toggle spring 31 is applied to the bundle carrying-out body 18, the back stopper 27 prevents the bundle carrying-out body 18 from rotating backward. However, when a very large force is applied, such as when the bundle delivery body 18 collides with an obstacle, the backstop 27 is bowl-shaped and low, so it passes over the receiving piece 24 and allows the bundle delivery body 18 to rotate backward.

In this way, when the bundle unloading body 18 is made to protrude laterally to take the bundle unloading attitude and the machine is moved forward, the grain culm pulled up by the grain culm pulling bodies 3, 3 is cut off by the cutting blade 1, and the guide plate 9 The grain culms that are leaning on the side are transferred to the horizontal conveyor belt 1.
1a and 11a toward the bundling device 13, and when the bundling device 13 ties the bundle and the release arm 12 releases the stock side of the bundle, the bundle delivery body 18 directs the ear side toward the mown field on the side of the machine. and carry it out.

When driving on the road after reaping work or when storing the reaping and tying machine, the front end side of the bundle delivery body 18 is lifted, and the back stopper 27 is lowered from the receiving piece 24. In this state, when the bundle delivery body 18 is rotated rearward as shown by the chain line in FIG. 5, the stopper 26 comes into contact with the rear surface of the front receiving piece 25, and the toggle spring 31 is moved as shown by the two-dot chain line in FIG. It moves rearward beyond the vertical axis 16 and maintains a constant storage posture.

Although the support frame 14 in the above-mentioned embodiment is composed of two iron plates, it may be composed of a single plate, and if necessary, receiving pieces 24 and 25 are provided at the front and rear parts of the support frame 14. All you have to do is set it up.

The present invention provides a harvester in which the base of a bundle transport body is pivotally supported on the bundle discharge side of a bundling device so as to be pivotable between a bundle transport position and a folded storage position, as described above, and a support frame for supporting the bundle transport body. , is constructed by bending both sides of the plate toward the bundle transporting body, and the bent portions serve as receiving pieces, and the bundle transporting body is placed at the base of the bundle transporting body to convert it into a bundle delivery position or a storage position. A stopper is provided that comes into contact with the inside of one of the receiving pieces and changes the bundle to the unloading position or the storing position when the bundle is removed.
A toggle spring is provided between the bundle transport body and the support frame to maintain the changed attitude beyond the pivot support when the bundle transport body changes its attitude, and the toggle spring is rotated rearward near the base of the bundle transport body. A backstop that prevents the bundle from moving is provided, and the backstop is configured with a small protrusion that can cause the receiving piece to pass through the related member due to distortion when an excessive pressing force is applied to the bundle conveying body from the front. Even if it is made of a relatively thin iron plate, the strength can be improved by the front and rear bent parts, and it can be made lightweight and inexpensive.
Furthermore, both of the bent portions can be used as receiving pieces at the front and rear of the stopper.

Furthermore, since only one stopper can be used, the cost can be halved compared to the conventional system in which two stoppers are provided.

Furthermore, even if the bundle carrier rotates backwards against the toggle spring due to machine shake or other factors, the bundle carrier is caught by the back stopper, allowing stable bundle delivery. If the vehicle collides with an obstacle,
Since the back stopper passes over the receiving piece and the bundle conveyor rotates backward, damage to the bundle carrier can be prevented.
