Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a straw binding device installed in a harvesting machine such as a combine harvester.

``Prior Art'' As a bundling deck used in this kind of bundling machine, there is, for example, one described in Japanese Utility Model Application Publication No. 58-125955.

``Problem that the invention aims to solve'' However, with this kind of structure, the deck is a fixed structure, and the string used to bind the waste straw must pass under the deck and pass through the tip of the needle of the tying machine. However, there was a drawback that this work was extremely time-consuming and troublesome.

``Means for Solving Problems'' Therefore, the present invention combines a main bundling deck that guides and supports the lower part of the waste straw to be tied, and a string brake member that applies a braking force to the strings that bind the waste straw. In the structure provided in the machine, an auxiliary deck having a tying string guide is rotatably connected to the main deck, and a slack removing member of the tying string is operatively connected to the auxiliary deck, and the auxiliary deck is rotated. When the brake force is released, the slack removing member is moved near the string brake member.

"Function" According to the present invention, during the string threading operation, the sub-deck is rotated so that, for example, the string guide provided on the back side of the sub-deck faces upward. This makes it easier to thread the string through the needle, and at this time, the slack removing member is automatically positioned near the string brake member that releases the brake force, thereby facilitating the threading operation. This will further encourage

6 are interlocked and connected, and by cranking the rod 52 when the gear 49 rotates, the aligning plate 35 is reciprocated about the fulcrum shaft 46. Note that 54 is a bundling roll provided behind the straw removal chain 21.

As shown in FIGS. 1 and 6, a string storage case 55 is provided on the right outer side of the transmission case 26, and a pair of string brake plates 57, which are string brake members, are attached to the front surface of the case 55 via a bracket 56.
58, and a string slack removing member 59 is provided on the left side of these brake plates 57, 58. A secondary deck 62 is attached to the front side of the main bundling deck 60 provided at the front of this bundling machine 19 via a rotational fulcrum shaft 61.
are connected reversibly upward, and left and right string guides 63 and 64 are integrally supported on both the left and right sides of the sub deck 62, and the string A in the case 55 is connected to the string brake plates 57 and 58, the string slack removing member 59, The cord is configured to be passed through the cord passage hole 24a of the needle 24 via the cord guides 63, 64.

The string guides 63 and 64 are engaged and connected to a first shaft 66 that is rotatably supported by a bearing plate 65 of the main deck 60, and are connected to the first shaft 66 by engagement of mounting plates 67 and 67 fixed to both ends of the shaft 66. The proximal ends of the string guides 63 and 64 are engaged with the grooves 68 and 68, and the sub-deck 60 is connected to the grooves 68 and 68 as shown in the imaginary line in FIG. 6 and the solid line in FIG.
The shaft 66 is provided so as to rotate clockwise when the shaft 66 is reversed upward about the fulcrum shaft 61. Further, a second shaft 70 is rotatably supported behind the first shaft 66 of the main deck 60 via a bearing plate 69, and each of these shafts 66, 70 is connected to a fixed swing arm 7.
1, 72 and a rod 73 so as to be rotatable in the same direction.

Furthermore, the second shaft 70 is interlocked and connected to a mounting plate 74 that supports the base end of the string slack removing member 59 via a fixed swinging arm 75 and a rod 76, and the mounting plate 74 is fixed to the right side of the main deck 60. The middle portion of the bracket 77 is pivoted for free horizontal swing via a shaft 78, and a bolt 79 is attached to one end as shown in FIG.
The slack-removing member 59 is rotatably connected to the other end thereof via the rod 76. The slack removing member 59 is formed of an elastic filament, and has a ring-shaped string guide part 59a at the tip and a ring-shaped multiple part 59b in the middle, and holds the string A by inserting it through the string guide part 59a. It is set up like this.

As shown in FIG. 9, the second shaft 70 is supported by a shaft holder 80 fixed to the bracket 56 so as to be slidable left and right, and a fixing pin of the second shaft 70 is inserted into a hook groove 81 of the holder 80. 82 is engaged, and the second shaft 70 is normally held in the leftward position by the force of the compression spring 83 interposed between the pin 82 and the bracket 56, and even when the handle 84 fixed to the right end of the second shaft 70 is operated. The second shaft 70 resists the force of the spring 83.
It is provided so that the braking force of the string A by the brake plate 58 is released when it is forcibly slid in the right direction. In other words, the brake plates 57 and 58 have their base ends held between the large diameter portion 70a of the second shaft 70, and are attached to a compression spring 87 which is attached to a screw 85 fixed to the bracket 56 via a nut member 86 so as to be able to adjust the spring pressure. These brake plates 57 and 58 are provided so as to be pressed against each other, and between the guide pins 88 and 89 fixed to the bracket 56, the pressure applied by the spring 87 of the brake plates 57 and 58 is used to apply the brake to the string A. While giving power,
When the handle 84 is operated to slide the second shaft 70 to the right against the force of the spring 83, the brake plate 58 that contacts the right side of the large diameter portion 70a is moved against the force of the spring 87 and the other brake plate 57, and the braking force on the string A is released. In this way, by sliding the handle 84 to the right, the brake force on the string A by the brake plates 57 and 58 is released, and the pin 82 and the hook groove 81
The handle 84 in the left end locking groove 81a
6, the slack removing member 59 is moved to the vicinity of the brake plates 57, 58 and the sub-deck 62 is reversed upward.

This embodiment is constructed as described above, and when threading the string A through the needle 24 before tying, etc., the second shaft 70 is pulled to the right by operating the handle 84. This enlarges the gap between the brake plates 57 and 58 to facilitate the string insertion between the brake plates 57 and 58, and then inserts the handle 84 into the groove 81a.
When rotating the pin 82 along the rod 7
6, and as shown in FIGS.
7, 58 near the lower position, and
The rod 73 is pushed forward as shown by the solid line arrow in the figure to move the sub-deck 60 about the shaft 61 in the direction of the arrow in the figure, thereby inverting it upward as shown in FIG. As a result, it is not only easy to pass the string through the string guides 63 and 64 of the sub-deck 60, but also because the sub-deck 60 is reversed, the string guide 63 comes close to the string-passing hole 24a of the needle 24. It is also easy to thread the string through the needle 24a, making it extremely easy to pass the string through the needle 24 from when it is unwound from the storage case 55 to the needle 24.

"Effects of the Invention" As is clear from the above embodiments, the present invention includes a main bundling deck 60 that guides and supports the lower part of the waste straw to be tied, and a string brake member that applies a braking force to the strings that bind the waste straw. 57, 58 in the binding machine 19, a sub deck 62 having binding string guides 63, 64 is rotatably connected to the main deck 60, and a slack removing member 59 of the binding string A is connected to the secondary deck 62. Since the slack removing member 59 is moved near the string brake members 57 and 58 which are interlocked and connected to the deck 62 and release the braking force when the secondary deck 62 is rotated, the secondary deck 62 is rotated. For example, by making the string guides 63 and 64 provided on the back side of the sub deck 62 face up, the string can be easily passed through the needle 24 through the sub deck 62. By automatically positioning the cord brake members 57 and 58 near the cord brake members 57 and 58 that release the brake force, the cord threading operation is further facilitated.
