Description

DETAILED DESCRIPTION OF THE INVENTION (A) Industrial Application Field The present invention relates to a bundle collection method in which a plurality of bundles bound and released by a binding device such as a binder, a combine knocker, or a harvester knotter are collected, and the bundles are collected and released in a field. Relating to a release device.

(B) Prior art Conventionally, the bundles released by the binding device are counted by a bundle counting mechanism, and when a predetermined number of bundles are collected, the drive mechanism is started by manually operating the 5-hand control lever, and the collected bundles are transferred to the field. A bundle collecting device for discharging a bundle is already known from Japanese Utility Model Application No. 58-187931.

(c) Problems to be Solved by the Invention In the known bundle collecting device, the drive device is activated by manual operation of a hand-operated lever, so the timing of operation of the bundle collecting device becomes inaccurate and the bundle collecting device opens and closes. Since the operating device was complex and had an integrated structure, timing adjustment was difficult.

(d) Means for Solving the Problems The present invention provides a bundle collecting and discharging device consisting of a stock receiver and a panicle side receiver, which is disposed outside the bundling device, and the bundle receiver is placed in a lowered bundle receiving position. The bundle collecting and discharging device is pivoted so as to be in an elevated discharge position, and the panicle side receiver is connected to a drive device that operates based on the detection signal of the east counting mechanism and a return operation section of the bundle counting mechanism. The release operation is carried out by a counting mechanism, and the return operation of the bundle receiver to its posture is carried out automatically at a certain appropriate timing by a separate interlocking system using the return operation section of the east counting mechanism. The above-mentioned problem was solved.

(e) Operation The bundles released from the binding device are counted by the bundle counting mechanism each time they are released, and when a predetermined number of bundles are collected in the east collection device, the drive clutch is activated and the ear side receiver is rotated upward. The collected bundles are released into the field, and when the release is completed, the return actuator of the bundle counting mechanism is activated to automatically return the bundle receiver that has lowered the ear side receiver to its posture.

(F) Embodiment An embodiment of the present invention and its related configuration will be explained with reference to the drawings.A binder is equipped with a cutting blade, a weed cutting body, and a culm pulling body 3, 3 on the front part of a machine body 2 having wheels 1.1. A leaning guide plate 4 and a horizontal conveying body 5 having a large number of protrusions on the conveying surface are provided at the rear of the cutting blade, and at the rear there is an engine 6 and a handle 7, side clutch levers 8, 8 attached thereto, and a speed change. A lever 9 and the like are attached, and a bundling device IO for bundling and releasing the culms guided and conveyed by the support guide plate 4 and the horizontal conveyance body 5 is arranged on the side of the cutting blade.

In addition, at the outer lower part of the binding device 10 and the canopy guide plate 4, there is a stock receiver 13 which is removably attached with a support shaft 11 in the front-rear direction and a hanging rod 12 hanging from the upper part of the culm raising body 3. An east collecting device is provided on the frame 14a and includes a panicle side receiver 15 which is pivotally supported on a horizontal shaft 14 so as to be able to move up and down. The culm is carried to the side of the aircraft by the horizontal conveyor 5 while leaning on the leaning guide plate 4, and the packer 16 of the bundling device IO scoops the harvested and conveyed culm into the collecting section 17 and collects it. When the amount reaches a predetermined amount and the door 18 senses it and operates, the needle 18 winds the string as in the conventional case, the knot part 20 consisting of a bill and a holder knots, and the discharge arm 21
releases the tied bundle to the side, and its stock part is stock receiver 1.
3, the panicle side protrudes outward from the cane guide plate 4 and hangs down inside the panicle side receiver 15, and is supported and guided by a flow guide 4a made of a flexible plate. It extends from the upper part of the body 3 to the frame body 14a, and also the panicle side receiver 1.
As shown in FIG. 2, the outside of 5 is guided by a frame 22 that serves as a guide and a guard, and is received by the ear receiver 15.

At this time, when the bundle counting mechanism 23 provided above the packer 16 and needle 19 of the bundling device 10 counts a predetermined number of bundles, it inputs a discharge signal to the drive clutch 26 via the wire 25, and the drive clutch 26 is connected to the axle shaft. Since the receiver driving mechanism 28 is actuated via the wire 27 by the power, the panicle side receiver 15 is tilted upward and the collected bundles are released into the field in a unified state.

Next, each device will be explained.

(I) Bundle counter I# mechanism The bundle counting mechanism 23 is the clutch case 10a of the bundling device 10.
A knotter cover 30 which is screwed onto the upper surface and has a U-shape when viewed from the side and whose upper part faces the lower part of the horizontal conveyor 5; It is rotatably supported on a shaft and the phase is 180'.
Ratchet wheel 33 with different pins 32.32
One end is integral with the shaft 31, and a ratchet pawl 3 is provided in the middle part.
a first link 36 having a needle rod 3 at one end;
a second link 38 that is loosely fitted onto the intermediate pin 38 of the second link 38 and whose other end is rotatably connected to the other end of the first link 36;
and the base is the pin 3 on the lower surface of the top plate of the knotter cover 30.
The detection arm 41 is rotatably fitted into the wire 25 and rotated by the pin 32 of the ratchet wheel 33, and the tip of the detection arm 41 has a spring 42 attached to the wire 25. The support arm of the needle 19 is connected to one end, and the support arm of the needle 19 is pivoted to a needle support shaft 43, the base is pivoted to the needle rod 37, and the tip of the needle rod 37 is connected to the crank of the needle crankshaft 45. Since the needle 19 is fitted into the crank pin 47 protruding from the arm 46, when the clutch is engaged for one rotation due to the sensing operation of the door and the crank pin 47 rotates, the needle 19 enters the knot part 20 through the converging part 17. The strap hook is activated, and at the same time, the second link 39 pushes the first link 3B, so the ratchet pawl 35 engages the reverse prevention pawl 4.
The ratchet wheel 33 held by the needle 19 is rotated back by one tooth, and then the needle 19 is rotated by one tooth to return the ratchet wheel 33.

When the bundle counting mechanism 23 is of a type that collects five bundles, FIG. 6(a) shows that after the collection of the fourth bundle is completed, the packer 16 scrapes the fifth bundle into the collecting section 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 the needle 19 moves back by one pitch.
9 moves to the return stroke, the ratchet wheel 3 rotates as the needle rod 37 rotates, as shown in FIG.
3 rotates, and the pin 32 pushes the detection arm 41 to rotate it clockwise, so the wire 25 inputs the discharge signal as a tensile force to the drive clutch 26, and at the same time rotates integrally with the first link 36. An operating arm 49 connected to a wire 48 that communicates with the receiver drive mechanism 28
rotates to the slack side.

(II) Driving Clutch The driving clutch 26 is provided with a clutch case 50 fitted onto an axle 51 as shown in FIGS.
A swinging arm 53 that is biased back at 3a is attached, and the swinging arm 53 has a pawl 54 that is curved along the outer periphery of the gear 52 and that engages and disengages from the teeth of the gear 52. The actuating arm 55 and the end of the wire 27 are rotatably connected, and an arcuate separation guide protrusion 57 is provided at the middle part of a cam part 56 formed on the inner surface of the clutch case 50 and consisting of a longitudinally long recess. The separation guide protrusion 57 guides the roller 58 pivotally supported at the tip of the actuating arm 55 so that it passes between the separation guide protrusion 57 and the gear 52 and over the upper part of the separation guide protrusion 57. Is the slope 5 gradually transitioning from the inner circumference to the outer circumference? It is formed in a.

Further, an arm 83 is fixed to a fulcrum pin 60 which is rotatably supported on the clutch case 50 and is connected to the pressing body 61 and the wire 25 via a spring 62.

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 the arm 6
3 is pushed down by the return spring 62, and the suppressing body 61 is rotated upward and into the retracted position, and the roller 58 of the actuating arm 55 is pushed down by the coil spring 53a.
Since the swing arm 53 is pushed up, the cam portion 56
The claw 54 is pressed against the upper right corner of the gear 52 in a rising position, and the pawl 54 is detached from the gear 52.

However, when the bundle counting mechanism 23 detects the fifth bundle, the wire 25 is pulled and the pressing body 81 pushes down the roller 58 as shown in FIG. The wires 27 are engaged with each other and rotated downward as shown in FIG. 3(b), thereby pulling the wire 27. As a result, the ear-side receiver 15 rotates upward as described above to perform eastward discharge.

When the roller 58 reaches the slope 57a of the separation guide protrusion 57, it is pushed outward by the driving force of the gear 52, so the roller 58 moves along the slope 57a and the wire 27 is pulled by the contact flame. , the claw 54 is shown in the same figure (
It is completely removed in the state shown in c), and since the swing arm 53 is urged upward by the coil spring 53a, the roller 58 is moved upward from the slope 5 of the separation guide protrusion 57. The roller 58 moves upward beyond the tip of the bundle a and returns to the position shown in FIG. When the sixth bundle starts binding and the ratchet wheel 33 of the bundle counting mechanism 23 rotates from the state shown in FIG. 6(C), the pin 32 fits into the notch 41a of the detection arm 41 and the wire 25 is relaxed, and as a result, the pressing body 61 is rotated back by the pressing force of the return spring [1'2, returning to the state shown in FIG. 9.

(II) Receptor drive mechanism Figures 12 to 16 show the receiver drive mechanism 28 of the ear side receiver 15, and the ear side receiver 15 has a gutter-shaped receiving part 15a and an arm part 15b.
The boss of the arm portion 15b is rotatably supported by the horizontal shaft 14 protruding from the frame 14a, and the receiver drive mechanism 28 is supported by a control pin 68 protruding from the arm portion 15b.
and a stopper pin 137, which is fixed to a mounting plate 65 integral with the horizontal shaft 14 and receives the control pin 66 at the upper and lower limit positions. f18, a drive element 70 whose base part is rotatably supported on the horizontal shaft 14 and which connects the end of the wire 25 from the drive clutch 2θ, and a lower part of which is the mounting plate 6.
The stopper lever 71 is rotatably supported by the stopper lever 71 to which the wire 48 from the operating arm 49 of the east counting mechanism 23 is connected, and has a stepped portion 71a.

When the bundles are being collected, the second ear side receiver 15 and the receiver drive mechanism 28 are in the state shown in FIG. As a result, the drive clutch 2B is actuated, the wire 25 pulls the driver 70, and the control pin 66 is moved to the upper stop 67.
Since the ear side receiver 15 is rotated upward until it comes into contact with the field, all the collected bundles are released into the field at once.

At this time, the wire 25 pulls the ear side receiver 15 until it contacts the upper stopper 67 as shown in FIG. 15 and then relaxes, so the driver 70 rotates downward and the ear side receiver 15 However, the stopper lever 71 is urged to rotate clockwise by the winding spring 72 and has entered the rotation locus of the control pin 6B.
As shown in the figure, the stepped portion 71a receives the control pin 66 and maintains the release posture of the ear receiver 15.

However, when the east counting mechanism 23 next detects the non-emission period, the actuating arm 49 moves up from the stopped position as the crank arm 46 rotates 90 degrees from the stopped position, as shown in FIG. 6(b). Since the stopper lever 71 rotates to the dead center degree and is pulled most thickly through the wire 48, the stopper lever 71 rotates counterclockwise, and the stepped portion 71a touches the control pin 66.
The panicle side receiver 15 descends due to its own weight and the control pin 6
6 is received by the lower stopper 68 and assumes the receiving posture.

Further, the first operating arm 49 rotates upward as shown in FIG. 6(C) while the needle 18 returns and rotates, and then returns to the state shown in FIG. 6(a) to relax the wire 48. Due to the action of the winding spring 72, the fourteenth
Return to the position shown in the figure.

In this way, the actuation system from the drive clutch 26 that raises and rotates the ear side receiver 15 to the ejection position and the actuation system from the counting mechanism 23 that puts it into the receiving position are separated and independent, so that the ear side receiver 15 It is possible to easily set the timing when the 15 is in the releasing position and the timing when it is returned to the receiving position to the optimum state, and the timing can be adjusted according to the operating conditions such as the culm length, the size of the bundles, or the number of bundles to be collected. Can be done separately.

In addition, even after the panicle-side receptor 15 is raised to the maximum level during release and unreleased, the stow/par lever 71 maintains the raised position, so unreleased can be performed more accurately, and the next bundle can be unreleased. Just before it is released, it descends and returns to the bundle receiving position.

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 body 14a and screwed therein.

(G) Effects of the Invention As described above, the present invention provides a stock receiver 13 on the outside of the bundling device 10.
A bundle collecting and discharging device consisting of a and a panicle-side receiver 15 is provided, and the panicle-side receptor 15 is pivoted so as to have a lowered bundle receiving attitude and an elevated release attitude. The bundle counting mechanism 2
Since the drive device operated by the detection signal No. 3 is linked to the return operation part of the bundle counting mechanism 23, the drive device can be activated by the output of the bundle counting mechanism without depending on the driver's feeling of the unreleased period as in the past. As a result, the panicle-side receiver rotates and unreleases, resulting in the release timing being too early and the last bundle released not being collected, or being released too late and making a mistake in receiving the next bundle. It can be carried out in a timely manner and reliably by using separate devices such as the release and return operation drive device of the panicle side receiver and the east counting mechanism. Moreover, unlike conventional devices, the configuration is complicated and the operation timing adjustment is not required. does not require complicated equipment.
