It is formed by attaching a reaping binding part.

A mounting device 8 extending from the machine body A is positioned on the outer side of the focusing space 7 of the binding machine 6 and is oriented approximately parallel to the front-rear direction of the machine body A. The stock base holding portion 9 of the device C is mounted by fitting the mounting tool 10 provided at its lower inner end so that it can rotate freely around the axis of the mounting tool 8.

The stock holding part 9 is provided with an upright wall 12 on the front and outer side of the bottom plate 11 on which the fixture 10 is provided, and the upright wall 12
The upper part is provided with a guide 13, and the inner end of the guide 13 is connected to the body A by a spring 14, so that the entire stock holding part 9 is attached to the mounting tool 8. It restricts downward rotation around the center.

Reference numeral 15 denotes a bundle receiving door, in which a fuselage-side fixing member 16 to be attached to the fuselage A side is placed in the rear space of the deck 5.
This fuselage side fixing member 16 is provided in a rearward tilted state substantially parallel to the
By rotatably mounting the mounting portion 17 on the bundle receiving door 1.
8 is attached, and the bundle receiving door 18 is provided with a receiving part 19, and this receiving part 19 is normally operated as shown by solid lines in FIGS. It is maintained in a standing reception position on the side of the aircraft, and at any time, it can be rotated toward the rear of the aircraft A and then returned to the standing reception position, as shown by the imaginary lines in Figures 1 and 3. It is configured as follows.

The opening/closing mechanism E is formed so that the detailed structure is shown in FIGS. A spring 23 is interposed and tensioned between a spring latching tool 21 that is fixed at an appropriate location and a latching portion 22 that is integrally fixed to the fuselage side fixing member 16, so that the bundle receiving door 18 can be erected. The spring retainer 21 is brought into contact with the side of a fixed cam 24 to prevent it from turning too much in the direction of arrow A, and this fixed cam 24 extends from the body A. It is held by the attached mounting member 25 and the aforementioned fixing member 16.

Further, a locking portion 26 is provided on the front edge side of the fixed cam 24,
A fulcrum shaft 2 installed on the actuating plate 20 is attached to this locking portion 26.
The engaging portion 29 at one end of the locking arm 28, which is provided to be able to swing about 7, can be engaged and disengaged, and the end of the locking arm 28 extending toward the opposite side from the fulcrum shaft 27 has a bundle amount. The detection part 30 is integrally attached, and the detection part 30 is positioned in front of the receiving part 19 of the bundle receiving door 18 so as to extend and protrude by an appropriate length, and when the locking arm 28 swings, the detecting part 30 is positioned in front of the receiving part 19 of the bundle receiving door 18.
It is configured so that it can come into contact with

An inner 32 end of the operating cable 31 is detachably connected to the end of the locking arm 28 to which the bundle amount detection unit 30 is attached, and the outer 33 is attached to a holding part fixed to the bundle receiving door 18. 34 and these inner 32 and outer 33
A return spring 35 is installed between the spring 3 and
5 urges the bundle amount detection unit 30 side of the locking arm 28 forward, and the extended end of the operating cable 31 is connected to the operating lever 36 and the guide latch 37 installed at the hand of the control device 2 as required. It is made by connecting.

Next, to explain the operation of the mechanism of the present invention constructed in this way, when starting the reaping and tying and the tied stem culm bundle collecting work by the reaping and tying machine, the bundle receiving door 1 of the stem culm bundle collecting device C is opened.
8 is held in a receiving attitude as shown by the solid line in FIG. At the same time, the eastern upper part is sequentially guided in the backward tilting direction along the guide 13 while standing upright, and the entire bundle is held in the backward tilting position by leaning against the receiving part 19. .

When this storage process is in the initial stage, the bundle group is discharged to the inner part of the stem and culm bundle collecting device C, so that the bundle group leans only on the receiving part 19 of the bundle receiving door 18, and the amount of bundles on the inside is detected. Since the bundle receiving door 18 does not come into contact with the part 30, the bundle receiving door 18 maintains its receiving attitude and continues to accommodate the bundle group.

Then, when the amount of stored bundles gradually fills up from the back of the stem and culm bundle collection device C, the storage side of the bundle becomes the entrance side of the stalk and culm bundle collection device C [closer to the machine body A], Finally, it is accommodated in the side area that comes into contact with the bundle amount detection unit 30, and when the amount reaches a certain level,
The bundle amount detection section 30 senses the weight and rotates about the fulcrum shaft 27 in the direction of the arrow.

Therefore, the engagement portion 29 at the opposite end of the locking arm 28 is also disengaged from the locking portion 26 of the rotating waist fixing cam 24 in the same direction, and the third
As shown by the virtual line in the figure, the bundle amount detection section 30 comes into contact with the bundle receiving door 18 and is no longer held in the bundle receiving posture, so that the load of the entire bundle weight applied to the receiving section 19 , the bundle receiving door 18 as a whole rotates around the fixing member 16 while resisting the spring 23 to move the receiving part 19 into the third position.
As shown by the one-dot chain line in the figure, it is turned significantly backward and inward, and the upper part of the stored stem and culm bundle group is discharged to the outside of the stem and culm bundle collecting device C.

When the stem culm bundle group is released and the load applied to the bundle receiving door 18 is removed, the restoring force of the spring 23 causes the bundle receiving door 18 to rotate in the direction of the return port in the opposite direction to the above, and the receiving part 19 closes the bundle. The engaging portion 29 of the hip locking arm 28 that returns to the receiving posture position engages with the locking portion 26 of the fixed cam 24 again to maintain that posture and prepare for the next east collection, as described above. The bundle group whose eastern upper part is released outside the stem culm bundle collection device C has its stock base also detached from the bottom plate 11 of the stock base holding part 9 as the aircraft A advances, and the bundle group is completely collected. It is released outside the device C.

In addition, when the amount of stem culm bundles in the stem culm bundle collecting device C has reached a sufficient amount to rotate the bundle receiving door 18 against the spring 23 due to its own weight, the group of stem culms is intentionally removed from the stem culm bundle. When attempting to remove the bundle from the bundle collection device C, by pulling the operating lever 36 at the hand, the operating cable 31 is activated to apply a load from the stem culm bundle to the locking arm 28 in a similar state. After that, the same operation as in the automatic operation described above is carried out to release the stem culm bundle group to the outside of the stem culm bundle collection device C, and the receiving part 19 is returned to the receiving position. It is possible to restore and maintain the state.

As described above, the present invention connects the mounting portion 17 to the fuselage side fixing member 1.
A bundle receiving door 18, which is rotatably installed on the body side fixing member 16, is biased to an upright receiving posture by a spring 23 interposed between a fixing member disposed integrally with the fuselage side fixing member 16. , and a locking arm 28 that swings around a fulcrum shaft 27 is provided on one side of the actuating plate 20 attached to the mounting portion 17, and one end of the locking arm 28 has an engaging portion 29 fixed to the body side. The locking arm 28 is locked to the locking portion 26 of the fixed cam 24 and pressed by the biasing force of the spring 35 to maintain the standing posture, and the opposite end of the locking arm 28 is configured to release the lock. At the same time, the bundle amount detection unit 3
0, and the detection part 30 is located in front of the receiving part 19 of the bundle receiving door 18, and when the weight of the stem culm bundle reaches a predetermined value, it shakes the locking arm 28. to rotate the bundle receiving door 18, and after releasing the stem culm bundle, the bundle receiving door 1
8 is designed to automatically return to its original position, the door that receives the stem culm bundle can be reliably held in the receiving position, and the door can be tilted open at the time of release and returned to the receiving position.
The opening/closing operation can be performed smoothly and reliably as specified, and the opening/closing operation can be performed both automatically and manually so that the opening/closing operation can be performed reliably.
