a second link 39 which is loosely fitted to the middle pin 38 of 7 and whose other end is rotatably connected to the other end of the first link 36;
A detection arm 41 is rotatably fitted into a pin 30a on the lower surface of the top plate of the ratchet wheel 33, and rotates when pushed by the pin 32 of the ratchet wheel 33.The tip of the detection arm 41 is attached to a spring 42.
The support arm of the needle 19 is connected to one end of the wire 25, and the base of the support arm of the needle 19 is pivotally supported by a needle support shaft 43, the base is pivotally attached to the needle rod 37, and the tip of the needle rod 37 is connected to the needle crankshaft. 45 crank arm 4
Since the needle 19 is fitted into the crank pin 47 protruding from the converging part 17, when the crank pin 47 is rotated by the one-turn clutch being engaged by the sensing operation of the door 18, the needle 19 enters the knot part 20 through the converging part 17. At the same time, the second link 39 pushes the first link 36, so the ratchet pawl 35 returns and rotates by one tooth of the ratchet wheel 33, which is held by the anti-reverse pawl 44, and then the needle 19 rotates. When returning, rotate the ratchet wheel 33 by one pitch.

If the bundle counting mechanism 23 is of a type that collects five bundles, FIG. From this state, when the needle 19 enters the knot 20 the most to bind and release the fifth bundle, the ratchet pawl 35 returns by one pitch, and then when the needle 19 moves to its return stroke, Needle rod 3 as shown in c
7 rotates, the ratchet wheel 33 rotates, and the pin 32 pushes the detection arm 41 to rotate it clockwise, so the wire 25 inputs the release signal as a tensile force to the drive clutch 26, and at the same time An operating arm 49, which rotates integrally with the first link 36 and is connected to a wire 48 leading to the receiver drive mechanism 28, rotates toward the loosened side.

() Drive Clutch The drive clutch 26 is provided with a clutch case 50 fitted onto an axle 51 as shown in FIGS. 8 to 11, and a gear 52 that rotates integrally with the axle 51.
and a swinging arm 53 that is biased back by a coil spring.
an actuating arm 55 having a pawl 54 that engages and disengages from the second tooth;
and the end of the wire 27 is pivotally connected to the end of the wire 27,
An arc-shaped separation guide protrusion 57 is protruded from the middle part of a cam part 56 which is a longitudinally long recess provided on the inner surface of the clutch case 50.
7 is a roller 5 pivotally supported at the tip of a swing arm 53
8 is guided to pass between the separation guide protrusion 57 and the gear 52 and over the upper part of the separation guide protrusion 57, and the left end is a slope 57a that gradually transitions from the inner circumference to the outer circumference.
It is formed in

Further, a fulcrum pin 60 rotatably supported on the clutch case 50 includes a pressing body 61 and the wire 2.
5 is returned and an arm 63 connected via a spring 62 is fixed.

As long as the number of bundles released and collected from the binding device 10 is less than 5 bundles, the bundle counting mechanism 23 does not output any output as shown in FIG. 9, and the wire 25 is relaxed, so that the arm 63 The pressing body 61 is pushed down by the return spring 62, and thereby the pressing body 61 is rotated upward and is in the retracted position, and the operating arm 55
Since the swing arm 53 is pushed up by the coil spring, the roller 58 is pressed against the upper right corner of the cam part 56 and is in a rising position, and the pawl 54 is disengaged from the gear 52.

However, when the bundle counting mechanism 23 detects and operates the fifth bundle, the wire 25 is pulled and the pressing body 61 pushes down the roller 58 as shown in FIG. The wire 27 is rotated downward as shown in FIG.

Then, the roller 58 rotates the separation guide protrusion 5
When reaching the slope 57a of No. 7, the roller 58 is pushed outward by the driving force of the gear 52, so the roller 58 moves along the slope 57a, and when the wire 27 is pulled to the maximum, the claw 54 is in the state shown in FIG. Since the swinging arm 53 is pushed upward by the coil spring, the roller 58 moves upward beyond the tip of the slope 57a of the separation guide protrusion 57 and returns to the position shown in FIG. At this time, since the bundling of the sixth bundle, which is the next collection group, has not started, the roller 58 is received by the pressing body 61, and the bundling of the sixth bundle has started, and the bundle counting mechanism 23
When the ratchet wheel 33 rotates from the state shown in FIG. Then, the state returns to the state shown in FIG.

() Receiver drive mechanism Figures 12 to 16 show the receiver drive mechanism 28 of the ear side receiver 15. The ear side receiver 15 consists of a gutter-shaped receiving part 15a and an arm part 15b. The boss is rotatably supported by a horizontal shaft 14 projecting from the frame 14a, and the receiver drive mechanism 28 is supported by a control pin 66 projecting from the arm portion 15b and a horizontal shaft 14.
stopper pins 67 and 68 fixed to a mounting plate 65 integral with the control pin 66 at upper and lower limit positions; A drive element 70 has a lower part rotatably supported on a mounting plate 65, and an upper part connects the wire 48 from the actuating arm 49 of the bundle counting mechanism 23, and a stepped part 71a. and a stopper lever 71.

When the bundles are being collected, the ear side receiver 15 and the receiver drive mechanism 28 are in the state shown in FIG.
3 is detected and actuated, which causes the drive clutch 26 to actuate and the wire 27 to pull the drive element 70 and rotate the ear receiver 15 upward until the control pin 66 abuts the upper stopper 67. All the bundles are released into the field at once.

At that time, the wire 27 connects the ear side receiver 15 to the 15th
As shown in the figure, the driver 70 is pulled down until it comes into contact with the upper stopper 67 and then relaxed, so the driver 70 rotates downward and the ear receiver 15 rotates downward due to its own weight.
The control pin 6 is biased to rotate clockwise by
6, the stepped portion 71a receives the control pin 66 as shown in FIG. 16 and receives the ear side receiver 15 as shown in FIG. Maintained.

However, when the bundle counting mechanism 23 next detects the timing for releasing the bundle, the actuating arm 49 moves upward from the stopped position as the crank arm 46 rotates 90 degrees from the stopped position, as shown in FIG. 6b. Since the stopper lever 71 rotates counterclockwise, the stepped portion 71a comes off from the control pin 66, and the ear receiver 15 descends due to its own weight. The control pin 66 is then received by the lower stopper 68 and assumes the receiving position.

Further, in the process of the return rotation of the needle 19, the actuating arm 49 rotates upward to the position shown in FIG. Return to the posture shown. Reference numeral 73 denotes a hole into which a mounting seat on the horizontal axis is moved and adjusted in the length direction of the frame 14a and screwed therein.

Furthermore, by setting the above-mentioned upper stopper 68 higher than in the above-mentioned example, the receiving surface of the ear side receiver 15 can be rotated more than vertically as shown by the chain line X in FIG. Even if grain culms of a standard culm length are bundled and discharged with the ear side receiver attached at a low position to fit the short culm, no discharge error will occur.

() Attachment/detaching device for bundle collection/discharge device The boss at the upper end of the arm portion 15b of the ear side receiver 15 is removably inserted into the horizontal shaft 14, and the outer end of the boss fits into the hole of the horizontal shaft 14. Since it is locked by a spring pin 14b that is inserted and removably inserted in
The ear side receiver 15 can be easily attached and detached by inserting and removing the spring pin 14b separately from the mounting plate 65 on which the drive elements 7, 48, the driver 70, the stopper lever 71, etc. are attached or held.

Further, as shown in FIG. 17, the support shaft 11 of the stock support 13 is loosely fitted into a bearing 77 that is integrated with an adjustment plate 76 having elongated holes 75, 75 in the vertical direction. a pair of spring pins 78,
The adjusting plate 76 is mounted so that the mounting position can be adjusted by means of a bolt 78, and the adjusting plate 76 is tightened with bolts 80, 80 to a receiver 79 screwed onto the transmission case on the node side, so that it can be adjusted up and down. At the same time, by pulling out the spring pins 78, 78 and removing the lower part of the suspension rod 12, the stock support 13 can be removed together with the support shaft 11.

Furthermore, the frame can be removed by removing the fixing pins 22a and 22b that fasten the front and rear parts of the frame 22.

Therefore, when mowing in the middle, headland mowing, or driving on the road, the stock receiver 13 is removed and the ear side receiver 1 is removed.
The bundle collecting and discharging device can be removed by removing the bundle collecting and discharging device 5 independently of its operating mechanism, and no adjustment of the operating mechanism of the ear receiver 15 is required when the bundle collecting and discharging device is installed for operation.

(g) Effects of the invention As described above, the present invention includes a bundle collecting and discharging device consisting of a stock receiver 13 and a panicle receiver 15 on the side of the bundling device 10. Since the drive element 70, which rotates between the receiving position and the releasing position and is removably supported on the shaft, is attached to the ear side receiver 15 as a separate component, it is possible to cut in the middle or to reap along the ridge. If the bundle collecting and discharging device becomes an obstacle to work as in the case of When the bundle is removed and subsequently transferred to the collection and discharge operation, the panicle receiver can be installed quickly and easily, and there is no need to adjust the interlocking mechanism, ensuring accurate collection and discharge of the bundle. You can continue working.
