A Rondo-shaped shutter 17 is provided in the closed position, and the grain culm bundles can be collected and stored in the grain culm storage frame 11 by arranging them vertically one after the other. The grain culm bundle is fed into the frame 11 from the binding part A by a plurality of feeding blades 18 provided at the grain culm bundle entrance 9.
This is carried out by a pair of upper and lower grain culm bundle feeding wheels 19 equipped with a grain culm bundle storage frame 11 that is unpacked after collecting a plurality of shell culm bundles.
The grain culm bundle is discharged from inside by operating the grain culm bundle discharge arm 20 supported by the frame 11. At the same time as the discharge arm 20 is operated, the grain culm bundle discharge port 16 is opened by displacement of the shutter 17. According to this invention, the ejection mechanism including the shutter 17 and the ejection arm 20 from inside the grain bundle storage frame 11 is constructed as follows. has been done.

That is, as shown in FIGS. 2 and 3, the grain culm bundle storage frame 11
At the rear end of the grain culm bundle discharger 16, the column 21 on the outer edge of the bottom plate 12 and the column 13 on the inner edge of the bottom plate 12 located opposite thereto are fixedly supported near the upper ends of both branches 21° 13. A support frame 22 of the release mechanism is provided, and a fourth
, 5, the grain culm bundle release arm 20 is formed by connecting a pair of upper and lower arms 20a along the longitudinal direction of the machine body, that is, the length direction of the storage frame 11, with a connecting plate 20b. The cylindrical body 20e provided at the end is slidably fitted onto a horizontal support shaft 23 fixedly supported by a support frame 22 and extending in the transverse direction of the fuselage, so that the standby position shown by solid lines and the standby position shown by chain lines in FIG. The shutter 17 is supported by the support frame 22 so as to be able to move forward and backward along the length of the storage frame 11 between the release action position in contact with the support column 21, and the shutter 17 is connected to the storage frame at the base end thereof. 11 After curving in the direction of the inner edge, the most proximal cylindrical body 17a is rotatably fitted onto a vertical support shaft 24 protruding from the upper surface of the horizontal crosspiece 22a of the support frame 22 along the fuselage transverse direction. The ejector 16 is supported by a supporting frame 22 so as to be rotatable between a closed position shown by a solid line in FIG. 4 and an open position shown by a chain line in FIG.

Similarly, as shown in FIGS. 4 and 5, the support frame 22 supports an operating lever 26 rotatably around a vertical shaft 25, and a fork 27 that is rotated by the operating lever 26 The cylindrical body 20eK of the grain culm bundle discharging arm 20 is clamped by the operating pin 20d fixedly disposed vertically, and the torque spring 28 normally rotates the discharging arm 20 in the direction of positioning it at the standby position shown by the solid line. When the operating lever 26 is rotated in the direction of arrow B, the grain culm bundle release arm 20 moves from the above-mentioned waiting position to the release action position shown by the chain line while being guided by the horizontal support shaft 23 and moving the length of the storage frame 11. The housing frame 11 is displaced toward the outer end along the direction of the housing frame 11, and when the operating lever 26 is released, it is returned to the original position by the action of the torque spring 28, and the shutter 17 is also pressed. An actuating plate 17b having a fixed length along the transverse direction of the storage frame 11 is fixed on the front side of the cylinder 17a, and is fixed to the cylinder 20c of the grain culm bundle release arm 20 on the front side of the actuating plate 17b. The tip of the bolt 29 screwed together is applied to the protruding plate piece 20e, and when the grain culm bundle release arm 20 is moved forward by operating the operating lever 26, the axis of the bolt 29 crosses the center line C of the cylinder 17a in the direction along it. From the moment when the shutter 17 is pushed by the discharge arm 20 through the shell culm bundle, the discharge arm 20 moves to the discharge arm 1 as shown by the chain line.

When the grain culm bundle releasing arm 20 is rotated toward the open position, and conversely, when the grain culm bundle release arm 20 is retreating, the bolt 29 moves the actuating plate 17b from the point at which the bolt 29 comes into contact with the actuating plate 17b, which is in the position shown by the chain line. is pressed, and the shutter 17 is rotated toward the closed position of the ejector 16 shown by the solid line.
It is designed to return to its original position.

The most retracted position of the buttonshell culm bundle release arm 20, that is, the above-mentioned waiting position, is regulated by the contact of the arm 20 with the support column 13.

Next, the inlet 9 in the illustrated grain bundle collection and discharge device 10
The side structure will be explained with reference to FIGS. 4 and 5. The grain culm bundle feeding wheel 19 is fitted onto a vertical rotating wheel 30 supported by the machine body outside the grain culm bundle storage frame 11. In addition, the three feeding blades 18 are provided with a phase difference of 120 degrees, and one of the feeding blades 18 is always positioned protruding from the grain culm bundle population 9. A cam plate 31 is fixed on the same axis 30 as the wheel body 19, and is provided with three rotation regulating surfaces 31a having a phase difference of 120 degrees. piston 3
2, a piston 32 formed in a rotation restriction member 32a whose end box engages with the rotation restriction surface of the cam plate 31 is slidably inserted into a cylinder 33 fixed to the fuselage, and is pressed against the cam plate by a compression spring 34. The feeding blade 18, which is biased to move in the 31 direction and is provided and is located at a position that protrudes into the grain culm bundle inlet 9 and receives the culm of the bundling part A, is normally moved against the rotation regulating surface 31a of the cam plate 31. The rotation of the shaft 30, and therefore the rotation of the grain culm bundle feeding wheel 19, is restricted by the rotation restriction surface 32a of the piston 32 supported by the compression spring 34, so that it is held in that position. However, when the shell culm binding is performed by the binding device 7 at the binding part A, and then the discharge arm 8 is rotated from the inside direction of the fuselage side to the exception direction,
The piston 32 is retracted by the discharge arm 8 through the bundled culm bundle against the action of the compression spring 34, and rotated integrally with the ring body 19 in the direction of the arrow in the figure, and at the same time The above-mentioned shell culm bundle is sent from the entrance 9 into the grain culm bundle storage frame 11 by the next-stage feeding blade 18 which enters into the grain culm bundle inlet 9 and rotates, and then the grain culm bundle feed wheel 19 The above-mentioned rotation is stopped when the rotation of the piston 32 is projected by the action of the compression spring 34 and the rotation restriction surface 32a of the piston 32 engages with the rotation restriction surface 31a of the next stage of the cam plate 31 when the paper rotates 120 degrees. The grain culm bundle feeding wheel 19 is held in that position until the next binding operation is completed.

A bundle holding plate 35 made of a spring plate whose base end is fixedly supported by the storage frame 11 is provided in the grain culm bundle storage frame 11 at a position facing the buttonshell culm bundle entrance 9 at an appropriate interval. can be,
The bundle of shell culms sent into the storage frame 11 as described above is temporarily held between the bundle presser plate 35 and the feeding blade 18 that can protrude into the inlet 9, and the next bundle of shell culms is fed into the storage frame 11. When the bundle is pressed by the next bundle of culms, the free end side of the bundle holding plate 35 is moved to the storage frame 11.
It is brought to the straight part within the storage frame 11 while being bent toward the outer end.

As described above, the bundle of cut husks that are intermittently bound at the binding part A is caused by the 0 intermittent rotation of the culm feeding wheel 19 at 120 degrees, which is linked to the operation of the discharge arm 8 after bundling. Therefore, the grain culm bundle storage frame 1 is moved by the feeding blade 18 of the wheel 19.
1 into the storage frame 11 in a standing position.
For example, when 5-6 bundles of husk bundles are collected and stored in this grain culm bundle storage frame 11 and the interior of the storage frame 11 is full, or Even if the inside of the culm bundle storage frame 11 is not full, when the reaping and tying machine is positioned at the edge of the ridge, the control lever 26 is rotated to release the grain culm bundle release arm 20 as described above. By slidingly displacing the grain culm bundle storage frame 11 from the inner end position toward the side edge along the length direction of the frame 11, and at the same time opening and rotating the shutter 17 in conjunction with the movement of the discharge arm 20. , a plurality of shell culm bundles arranged vertically back and forth in the grain culm bundle storage frame 11 are released by a release arm 20 into a grain culm bundle release slot 1.
By sweeping the shell culm bundles in six directions with the foot-sweeping plate 15, the plurality of shell culm bundles can be released simultaneously. By separating the shutter 17 and the grain culm bundle release arm 20
is automatically returned to its original position as described above, but the grain culm bundle collecting and discharging device 10 according to the present invention has a grain culm bundle discharging mechanism configured as described above. In particular, it has the following advantages:

That is, the grain culm bundle collecting and discharging device in the reaping and tying machine of this invention includes a grain culm bundle discharging arm for discharging the multi-hulled culm bundles collected and stored in an upright position in the grain culm bundle storage part, and the grain culm bundle storage part. Since the shutter at the outer end is interlocked and connected so that the shutter is opened and closed in conjunction with the advance and retreat of the discharge arm, compared to a case where the discharge arm and the shutter are configured to be operated separately, A device design that allows the grain culm bundle release mechanism to be operated only once, making the operation easy, and also synchronizes the timing of the release operation of the release arm and the opening/closing operation of the shutter so that the optimal grain culm bundle release operation is performed. In particular, the grain culm bundle discharging arm that runs along the length of the grain culm bundle storage can be moved back and forth from the inner end of the storage part toward the outer end along the length direction of the storage part. Since the discharging arm is designed to extrude multiple shell culm bundles simultaneously, unlike the rotating discharge arm, the multiple shell culm bundles are aligned in the grain culm bundle storage section. It can be released in an orderly manner while maintaining alignment,
It exhibits remarkable advantages such as smooth release of grain culm bundles, prevention of grain shedding, and easy collection after release.
