Description

[Detailed Description of the Invention] [Industrial field of application] In the present invention, the discharged straw fed from the threshing device in a sideways posture is dropped and supplied to a large number of blades rotating around a horizontal axis to be shredded and discharged. More specifically, the present invention relates to a technique for smoothly supplying the discharged straw to the discharged straw shredder.

[Conventional technology]

Conventionally, as a technique for smoothly supplying the discharged straw to the shredding device configured as described above, the actual open sho 56-13
There is one shown in Japanese Patent No. 1749, and in this conventional example,
A member for guiding the waste straws from the threshing device to the side of the blade is provided above the blade that is driven to rotate so as to be elastically swingable.

[Problems to be solved by the device]

However, assuming the case of carrying out the harvesting work by mounting the threshing device of this conventional example on a combine, the working situation, or, because the volume of the straw discharged from the threshing device is not constant depending on the growth situation of the grain culm, for example, If the volume of the discharged straw is extremely large, the guiding member swings to the limit, and as a result, the force that tries to restore the member acts on the discharged straw, pressing the discharged straw against the path wall to reduce the conveyance resistance. It is also possible to increase.

Further, in the waste straw shredding device having a structure in which the waste straw is dropped and supplied to the blade body that is driven and rotated as in the above-mentioned reference, since the blade body rotates at a relatively high speed, the waste straw when being sent to the blade body Depending on the falling position and the like, the discharge straw may be flipped up, and there is room for improvement in terms of smooth conveyance of the discharge straw.

An object of the present invention is to obtain a structure for smoothly sending the discharged straw to the shredder even when the discharged straw having a very large volume is sent or even when the discharged straw is flipped up by the blade.

[Means for solving the problem]

A feature of the present invention is, as described above, in a waste straw shredding device having a blade body, which is capable of retracting and deforming above the blade body along the feeding straw discharge direction from the threshing device, and at the same time. A plurality of elastic rods for guiding to the breaking point are arranged, and the elastic rods are switched between the backward swingable state and the non-swingable state at least at the upper end position of the elastic rods on the stock root side of the discharge straw. It is provided with a free pivotal connection mechanism, and its action and effect are as follows.

[Action]

According to the above feature, when a relatively large volume of discharged straw is sent, the elastic rod is moved backward to guide the discharged straw to the shredded portion, and when an extremely large volume of discharged straw is sent. When the pivot support mechanism is set to the backward swingable state, the elastic rod swings greatly backward and guides the discharge straw to the shredded portion, so that the force due to the restoring force of the elastic rod causes the discharge. This makes it possible to eliminate the harmful effects of pressing the straw against the path wall, and further, even when the discharge straw is flipped up by the blade, the elastic rod prevents the discharge straw from being lifted.

[Effect of device]

Therefore, even when the discharged straw having a very large volume is sent or even if the discharged straw is flipped up by the blade body, a structure can be obtained in which the discharged straw is smoothly sent to the shredding device.

〔Example〕

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

As shown in FIG. 4, the waste straw shredding device (A) that shreds and discharges the waste straw sent from the threshing device (1) in the sideways posture, and the waste straw from the threshing device (1) remains in the sideways posture. The tying device (B) for tying, and the tying device (C), which changes the tying device from the tying device (B) to the vertical position by feeding the tying device from the tying device (B) to the upper rear direction, and releases the tying device (C) in a standing position in a field scene It is provided in the to configure the combine.

The discharge straw shredding device (A) is a disc-shaped blade body (4), (4) at predetermined intervals in the axial direction with respect to the lateral shafts (3), (3) that are driven and rotated, respectively. .. is provided in a case (5) in which a pair of cutters are housed. When the waste straw is shredded, the lid (6) at the upper part of the case (5) is used by swinging.

Further, as shown in FIG. 3, a plurality of elastic rods (7) for guiding the discharged straw from the threshing device (1) to the shredded portion are suspended from the lid body (6). The elastic rods (7) are provided so as to be retractable and deformable along the feeding direction of the discharge straw.

As shown in FIG. 1 to FIG. 3, the elastic rods (7) around the axis (P) are located above the predetermined number of the elastic rods (7). There is provided a pivotal connection mechanism (D) which can be switched between a state in which it can be swung backward and a state in which it can not be swung.

This pivotal support mechanism (D) comprises a hinge (8), a bracket (9) and a knob (10), for example, as shown in FIG. 2 when a discharge straw having an extremely large volume is sent. By removing the knob (10), the elastic rod (7) is set in a freely swingable state so that the discharged straw can be smoothly guided.

As shown in FIG. 4, the binding device (B) has a needle (12) and a drive case (13) arranged above the binding space (S), and a knot mechanism (14) below the binding space (S). , The discharge arm (15) is arranged, and the discharge device (C) further comprises
An endless chain (16) for taking out the power of the drive case (13) of the binding device (B) and a pulley (17) driven by the power from the endless chain (16) and each having an axial center direction shifted by about 90 degrees. , Endless belt (18) wound around (17),
The endless belt (18) is provided with a holding rod (19) for pressing the binding discharge straw (2).

The holding rod (19) is, as shown in FIG. 5, a spring (not shown) with respect to a bracket (21) provided at the tip of the arm (20) from the binding device (B) side, Further, the exclusion plate (23) is supported by the rod (22) so that the bent portion of the binding discharge straw (2) does not become entangled with the rod (22) during the work, and the exclusion plate (23) is removed from the holding rod (19). It is provided across the rod (22).
