Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a bundle guide device in a binder bundle collection and discharge device that collects and discharges a plurality of bundles to be bound and discharged by a binding device.

(b) Prior art Conventionally, there has been a binder in which a leaning guide plate is provided at the rear of the cutting blade, and a bundle collecting and discharging device consisting of a stock receiving body and a panicle side receiving body rotating around a horizontal axis is provided on the outside of the binding device. A bundle collecting and discharging device is already known from Japanese Patent Laid-Open No. 156220/1983.

In addition, a bundle collection device in which the panicle side receiver was configured to move up and down around an axis in the front-rear direction was developed in 1977.
-Already known from Publication No. 201126.

(c) Problems to be solved by the invention Among the known binder bundle collecting and discharging devices, the former is characterized in that when the binding device discharges the bound bundles toward the bundle collecting and discharging device, the ears are held in a bundle receiving posture. Because the support part of the side receiver is high, the transition of the bundle from the canopy guide plate to the ear side receiver becomes uneven, and the amount of movement from the ear side to the stock head is less, which disrupts the discharge posture to the field and causes the machine to There were times when it fell to the side and Hobe was trampled by the wheels.

In addition, in the latter case, when the panicle-side receiver rotates downward, the bundle on the tip side falls first, and the bundle on the center side of rotation falls last, so it is collected by the stock receiver and the panicle-side receiver. All the bundles that have been collected are discharged onto the field and are shifted back and forth, and when carrying these bundles, it is necessary to align the bundles. There were problems such as the need for separate transport means for transporting the ears of the bundle to the ear side receiver.

(d) Means for solving the problem The present invention provides a leaning guide plate at the rear of the cutting blade, a stock receiver on the side of the binding device for binding the harvested grain culms, and a structure that is approximately perpendicular to the direction of movement of the machine. A bundle collecting and discharging device consisting of an upwardly U-shaped panicle side receptor that moves up and down about a horizontal axis is provided, and has flexibility from the terminal end of the cane guide plate to the panicle side receptor. At the same time, a flow guide having an outer side hanging down is provided, and the lower end of the flow guide faces into the upward U-shaped ear side receiver, and the flow guide directs the ear side of the grain culm bundle thrown by the bundling device to the ear side. The above-mentioned problem was solved by guiding the slide into the receiver.

(E) Effect The stock receiver receives the stock base of the bundle bundled and released by the bundling device, and the panicle side is caught on the side of the panicle side receiver from the side of the cane guide plate as a result of the release action. It slides down on the flow guide and enters the panicle side receiver without any movement, and can be collected in an orderly tangled state. Because of this movement, the ears of each bundle fall at approximately the same time, so that the bundles released into the field are well aligned.

In addition, the panicle side receiver rotates downward when releasing the bundle, and then rotates upward to return to the bundle receiving posture, but the flow guide is flexible and protrudes laterally to form an upward U-shape. Since it has returned to the position facing into the ear side receiver and is hanging down, it does not become an obstacle when the ear side receiver returns to the receiving position and rotates.

(f) Embodiment An embodiment of the present invention and its related structure will be explained with reference to the drawings. A binder is attached to the front part of a machine body 2 having wheels 1, 1, a cutting blade, a grass cutting body, and a grain culm pulling body 3, 3.

When the needle 19 is drawn into the part 17 and focused, and when the focused amount reaches a predetermined amount and the door 18 senses it and operates, the needle 19
wraps the string, the knotting section 20 consisting of a bill and a holder knots, and the release arm 21 releases the tied bundle to the side, the stock base rests on the stock receiver 13, and the panicle side leans down. It is supported and guided by a flow guiding guide 4a made of a flexible plate that projects outward from the guide plate 4 and hangs down inside the ear side receiver 15, and on the outside, from the upper part of the grain culm pulling body 3, the frame body 14a At the same time, it detours around the outside of the ear side receiver 15 as shown in FIG. 2, and is guided by a frame body 22 that serves as a guide and a guard, and is received by the ear side receiver 15.

At this time, the bundle counting mechanism 23 provided above the bundle car 16 and needle 19 of the binding device 10 emits a signal to the wire 25 when a predetermined number of bundles is counted.

Next, each device will be explained.

() Bundle Counting Mechanism The bundle counting mechanism 23 is screwed onto the upper surface of the clutch case 10a of the bundling device 10, and has a U-shape in side view, and includes a knotter cover 30 whose upper part faces the lower part of the horizontal conveyor 5, and its upper part. A cover 30b having an inverted L shape, a pin 32 rotatably supported on the top plate by a shaft 31, and having a phase difference of 180 degrees,
32, a first link 36 whose one end is integral with the shaft 31 and has a ratchet pawl 35 in the middle, and a first link 36 whose one end is connected to the needle rod 3.
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 which is biased back by a coil spring 53a.
The end of the wire 27 is rotatably connected to an operating arm 55 which is curved along the outer circumference of the gear 52 and has a pawl 54 that engages and disengages from the teeth of the gear 52. An arcuate separation guide protrusion 57 is protruded from the middle part of the cam part 56 which is a longitudinally long recess provided on the inner surface of the cam part 56 . It 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 formed into a slope 57a that gradually transitions from the inner circumference to the outer circumference.

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 53a, the roller 58 of the cam part 56
The claw 54 is pushed against the upper right corner of the gear 52 in a raised position, and the pawl 54 is detached 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 pulled by rotating 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. The swing arm 53 is completely removed by the coil spring 53a.
Since the roller 58 is urged upward by
moves upward over the tip of the slope 57a of the separation guide protrusion 57 and returns to the position shown in FIG. is the pressing body 61
When the sixth bundle begins to be tied and the ratchet wheel 33 of the bundle counting mechanism 23 rotates from the state shown in FIG.
When the wire 25 is fitted into the notch 41a of the
It rotates back due to the pressing force and 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 that are fixed to a mounting plate 65 integral with the drive clutch 26 and that receive the control pin 66 at the upper and lower limit positions; A drive element 70, which connects the end of the wire 27 from above, and a driver element 70 whose lower part is rotatably supported by a mounting plate 65, connects the wire 48 from the actuating arm 49 of the bundle counting mechanism 23, and connects the step part 71a. The stopper lever 71 has 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 and maintains the release posture of the ear-side receiver 15, as shown in FIG.

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 as shown in FIG.
The action returns to the posture shown in FIG. 14. 7
Reference numeral 3 designates a hole into which a mounting seat on the horizontal axis is moved and adjusted in the length direction of the frame body 14a and screwed therein.

() Bundle guide device At the discharge side end of the stand guide plate 4, there is a flexible plate made of a plate made of rubber or synthetic resin, or a flexible member made of a series of guide surfaces made of a plurality of elastic rods. A flow guide 4a is fixed as shown in FIGS. 1 and 2, and the flow guide 4a projects outward and then hangs down to the inside of the upright part of the ear side receiver 15 on the machine body side. Since it is invading the bundling device 1
The ears of the bundle released from the side part of the cane guide plate 4 are continuously guided to the flow guide 4a, and slide down the upper surface of the flow guide 4a to enter the ear side receiver 15. is a horizontal axis support system, on both sides of the receiving surface,
In particular, even though there is an upright part on the body side, the ear part smoothly slides down and is stored in an orderly manner without being obstructed by the upright part.

Furthermore, although the panicle receiver 15 moves up and down each time the bundle is discharged, the flow guide 4a has flexibility and maintains a posture facing into the panicle receiver 15. Even if it is bent toward the body side during release, the return operation is performed almost simultaneously with release, the return operation of the ear side receiver 15 is not obstructed, and the guide is smoothly guided while adapting to the ear part. Moreover, even if no conveyance means is provided on the outside of the canopy guide plate 4, the lower end is connected to the panicle side receiver 15.
The flow guide 4a facing inward and having flexibility allows the grain to be reliably dropped into the panicle receiver 15.

(g) Effects of the invention The invention provides a support guide plate 4 at the rear of the cutting blade,
A stock receiver 13 is attached to the side of a binding device 10 for bundling harvested grain culms, and an upward U-shaped ear receiver 15 that moves up and down about a horizontal axis substantially perpendicular to the running direction of the machine body.
A flow guide 4a having flexibility and a hanging outer side is provided extending from the terminal end of the canopy guide plate 4 to the panicle side receiver 15, and a lower end of the flow guide 4a is provided. is configured to face inside the upward U-shaped ear side receiver 15 and guide the ear side of the grain culm bundle thrown by the binding device 10 to slide down into the ear side receiver 15 by the flow guide 4a. Therefore, when the bundle bound by the binding device is discharged toward the bundle collection/discharge device, the panicle side of the bundle is guided to slide down by the flow guide 4a and into the panicle side receiver 15 due to the discharge action of the binding device. The flow can be made to flow smoothly, without causing movement obstructions unlike conventional ones, and furthermore, the flow guide 4a can be bent and moved toward the ear side without having to attach a separate conveying device to the outside of the canopy guide plate 4. The collected bundles can be neatly collected in the U-shaped panicle side receiver 15 without leaking, and the collected bundles can be rotated around a horizontal axis that is substantially orthogonal to the running direction, so that the panicle side of each bundle can be collected neatly without any leakage. They are released almost at the same time and are discharged to the field in an orderly and well bundled state, which prevents them from being stepped on by wheels and facilitates subsequent bundle processing.

In addition, although the flow guide 4a hangs down from the stand guide plate 4 into the panicle side receiver 15 and bends toward the machine body when the bundle is released, it returns to the direction away from the machine body due to its flexibility immediately after the bundle is released. It operates and returns to the attitude facing the inside of the ear side receiver 15 all at once, so that there is no obstacle to the return rotation of the ear side receiver 15.
