2 and 5 show a binding space discharge mechanism of the binder according to the present invention, and FIG.

3 is a plan view of the main portion of the mowing device and the binding device.

4 is a side view of the binding device.

5 is an explanatory view of the operation of the discharge mechanism.

The present invention relates to a binding section discharge mechanism for releasing a bundle of grain stems bound after mowing in a binder to the outside of the gas.

The binder is provided with a harvesting device which harvests and conveys the grain stems of the tillage, and a binding apparatus which binds the conveyed grain stems and discharges them outside the gas.

Thus, the grain stem of the arable land scraped off by the herbicide at the front end of the mowing device is conveyed while being raised in the vertical state by the causing device, and scraped onto the mowing blade by the stirring wheel at the conveying end part.

The harvested grain stem is introduced into the binding passage and bound by a predetermined amount by the binding mechanism installed in the binding apparatus, and then discharged outside the gas by the discharge mechanism attached thereto.

FIG. 1 is a plan view of the discharge mechanism in the related art, and this is explained based on this drawing. The transfer of the grain stem 1 which is carried out by the cutting blade which is not shown in figure, and is sent in the direction indicated by the arrow A in the figure is shown. The path is provided with a T-protrusion 3 which rotates in the direction indicated by the arrow B in the drawing about the T-protrusion shaft 2 and a plateform 4 that guides the root portion of the grain stem 1. The grain stem 1 is bound by a binding mechanism not shown in the position shown in the figure.

On the other hand, a rotary arm 6 is integrally formed on the timing gear 5 which rotates in the direction indicated by the arrow C in the figure in order to drive the binder of the binding mechanism, and swings on the side of the timing gear 5. The arm 7 is rocked around the arm shaft 8.

Thus, at the distal end of the rotary arm 6 and the swinging arm 7, the upper and lower discharge arms 9 and 10 and the connecting pipe 11 connecting the upper and lower ends are integrally formed and pivotally attached. In this way, a link-shaped discharge mechanism 12 is formed.

In such a conventional binding device, when the grain stem 1 reaches a predetermined amount, the T-protrusion 3 rotates slightly, the clutch enters, the timing gear 5 rotates at a predetermined angle, and the grain stem 1 is bound.

When the timing gear 5 rotates again, the rotary arm 6 rotates with the timing gear 5 in the circular trajectory of the drawing, and the swinging arm 7 swings in the circular arc trajectory of the drawing.

As a result, the discharge arms 9 and 10 are linked by the link movement along the trajectories shown by solid lines 9 and 10 and dashed lines 9A, 10A and 9B and 10B in the drawing. Release 1) out of gas.

Therefore, in this conventional discharging mechanism, as is apparent from the trajectory of the discharging arms 9 and 10 shown in the drawing, in the first half of the discharging operation, the distal end of the pivoting arm 6 is mainly moved toward the left and right in the drawing to discharge. The arms 9 and 10 also move in the same direction together with this to release the grain stem 1, but they are pressed against a large number of members on this side, such as the T-protrusion shaft 2 or the wall of the cover 13. The operation is large, and there is a inconvenience that the release is not performed smoothly, and when it is severe again, the tip of the release arms 9, 10 enters the curved legs and inhibits the release operation.

SUMMARY OF THE INVENTION The present invention has been made in view of the above. By artfully configuring a link mechanism including an ejection arm, the interlocking grain section is extruded in a direction substantially orthogonal to the direction of travel of the base in the first half of the ejection operation, and obliquely in the second half. It is to provide a binder intermittent discharge mechanism of the binder which is extruded toward the front to make the discharge of the grain stem extremely smooth.

Hereinafter, the structure etc. are demonstrated in detail by the Example which shows in a figure. In the figure, the binder shown by the code | symbol 21 in the whole becomes the drive part 22 and the harvesting | reaping part 23, These are attached / detached freely by the connection mechanism not shown.

The engine 22 is mounted on the driving unit 22, and the rotation thereof is transmitted to one driving wheel 26 via a transmission in the gearbox 25 and branched from the pressure shaft of the gearbox 25. It is transmitted to the mounting 23.

Moreover, the operation box 27 which operates the main clutch for driving is attached to the side of the engine 24, and the string case 28 which accommodates a string for binding is provided in the front of the engine 24 again. have.

On the other hand, at the front end of the harvesting section 23, the grass dividing bodies 29 and 30 which scrape off the grain stem of the arable land are supported and installed for the supported distillation along the ground.

Again, between the right and left herbaceous bodies 29 and 30, the chain casing 31a and the pulling device 31 made of a pulling chain extending therein are raised rearward as they are directed upward. As a result, a plurality of protrusions 31b are arranged in the attracting chain of the popular apparatus 31 at regular intervals, and the uncut section 32 shown in FIG. 3 is driven by the running of the pulling chain. It is constructed as if the tip of the ear is preserved and conveyed and it is brought up in a vertical state.

Moreover, the grain stem guide 33 formed in the rod shape is supported by the conveyance path | route of the uncut section 32.

In addition, at the end of the conveying path, a cutting blade shaft 34 which is driven by the engine 24 described above through the conduction shaft and rotates in the direction indicated by the arrow D in the drawing is installed upright. Stirring wheel 35 and the rotating disc 36a used for putting into it, and the rotary blade 36 which consists of the eight triangular blades 36c arrange | positioned at the periphery are axially arranged in parallel.

On the other hand, a pair of left and right sleds 37 and 38 which are mounted on the lower part of the grass for supporting the above-described herbicides 29, 30, etc. and which are driven in contact with the ground are installed. The chain case 39 extending parallel to the conveyance path of the uncut section 32 as shown in FIG. Attached.

In addition, the guide support plate 40 attached to the center portion of the chain case 39 has a blade holder for cutting this and the uncut blade 32 in a V-shape against the triangular blade 26b which comes back from the electric circumference. (41) is attached.

In addition, a plate form 42 formed in a U-shape in a plan view is fixed to the outer side of the blade receiving plate 41, and the protrusion portion of the plate form 42 is formed in an arc shape by a thin plate. The grain stem support 43 which protrudes toward the upper side of the chain case 39 is attached with a screw.

Therefore, the grain stem is extruded by the rotary blade 36 to the harvesting grain conveyance path | route formed along these plateforms 42 and the grain stem 43. As shown in FIG.

On both sides of this conveyance path, a binding device comprising a drive mechanism 44, a binding mechanism 45, and a discharge mechanism 46 is disposed.

The double drive mechanism 44 includes a cam shaft 47 chained with a conductive shaft for driving the aforementioned cutting blade shaft 34, a lever shaft 48 geared with the cam shaft 47, and the lever shaft 48. ) And a T-projection shaft 49 connected via a clutch mechanism (not shown) are disposed in a triangular shape.

Thus, the T-protrusion shaft 49 pivots by the pressure between the cutting music extruded into the binding passage and connects the clutch, so that the T-protrusion 52 which rotates the needle 50 for the string length and the sprocket 51 is attached to the shaft. It is done.

On the other hand, the binding boss 53 of the binding mechanism 45 is installed integrally with the chain case 39 on the opposite side of the t-plate 52, which is the electric platelet 42, and the sprockets are The binding shaft 55 driven by the 51 and the chain 54 is freely axially rotatable.

Therefore, at the upper end of the binding shaft 55, a timing gear 56, which has teeth on a portion of the outer peripheral portion of the lower surface and which rotates in the direction indicated by the arrow F in the drawing, is engaged with the binding shaft 55. . The upper end of the binding boss 53 is integrally formed with arms protruding radially in three directions, two of which support the electrical plate form 42, and the support portion has an arc shape. It is connected by the binder base 57.

The binder base 57 is rotatably mounted with a binder bill 59 and a string holder 60 having a pinion 58 engaged with the teeth of the timing gear 56 described above. On the other hand, the remaining arms 61 of the three arms mentioned above are protruded at an oblique front, and an axis 62 is installed at the tip thereof, and the axis 62 is a swing lever of the discharge mechanism 46 described above. 63) is condensed toward the free end toward the inside of the base. In addition, the upper end portion of the above-mentioned binding shaft 55 is formed in an L shape by the support portion 64a and the projection portion 64b, and is pressed by the pin 65 implanted on the upper surface thereof by the rotation of the timing gear 56. The rotary lever 64 which rotates together is placed on the upper side of the timing gear 56.

Therefore, the pivot levers 66 and 67 are implanted at the distal end of the rotation lever 64, respectively, and the pivots 66 and 67 are formed in an arc shape so that both levers 63 It is connected by the connecting rod 68 which links with 64.

At the upper end and the lower end of the connecting rod 68, the discharge arm 69 formed in a straight shape and the discharge arm 70 formed in an arc shape are integrally formed as extending toward the above-described cutting path between the cutting pieces. have. In addition, the swing lever 63 is provided with elasticity in a direction away from the timing gear 56 by the tensioned spring 71.

With this configuration, the discharge mechanism 46 is discharged from the arm 69 and 70 by the link motion of the connecting lever 68 and the swinging lever 63 connected thereto when the rotary lever 64 rotates. Moves in the trajectory as shown in FIG. The operation of the binder 1 configured as described above will be described.

The uncut sheet 32 which is scraped off by the herbaceous bodies 29 and 30 and introduced into the conveying path with the progress of the expectation is attracted by the popular device 31, and is conveyed in succession to the grain stem guide 43. do.

The conveyed non-cutting blade 32 is released from the grain stem guide when it reaches the conveying end part, and between the triangular blade 36b of the rotary blade 36 and the blade receiving blade 41 by the stirring wheel 35. It is mowed by the triangular blade 36 which is scraped and turns around.

The harvested grain stem is extruded to the harvesting grain stem conveyance path by the scraping action of the stirring wheel 35 and the crank action of Parker (not shown) to press the T-protrusion 52.

Thus, when this cutting edge reaches a predetermined amount, the needle 50 is rotated by connecting the clutch (not shown) by the T projection 52 by the pressure, and the binding string is rolled up between the cutting edges.

At the same time, the timing gear 56 of the binding mechanism 45 is rotated by the drive of the chain 54, and at the end of the binding string rolled up between the grain stem by the binding bill 59 and the string holder 60 driven by this. A knot is formed.

Therefore, when the timing gear 56 is stopped, the rotation lever 64 is biased by the spring 71 in which the swing lever 63 is tensioned so that the projection 64b abuts against the pin 65 and stops. When the timing gear 56 starts to rotate, the pin 65 is moved away from the projection 64b, contacts the support portion 64a of the rotary lever 64, and rotates it together.

By rotating the rotary lever 64, the discharge arms 69 and 70 move with a trajectory as shown by the broken line in FIG.

That is, as shown by the solid line in the figure, the discharge arms 69 and 70 which stop and move the tip end to the position evicted from the conveying path in addition to the tensioned spring 71 are rotated by the rotation lever 64. By the end of the discharge path is almost parallel to the return path to reach the discharge end portion, the leading end is sent to the transport path.

After that, the ejection operation is started, and the front end portions of the ejection arms 69 and 70 in the first half of the ejection operation are moved in the direction of the T-protrusion shaft 49 because they are moved in the direction of the conveyance path with a loose arc-shaped trajectory. There is no pressure bonding, and the T-projection 52 is rotated at the position shown by the dashed line in the drawing, and the grain stem is extended to the discharge arms 59 and 60 between the T-projection 52 and the plate form 42. Therefore, it is released.

In the latter part of the discharging operation, the traces of the distal ends of the discharging arms 59 and 60 follow the traveling direction of the base toward the oblique front of the base, so that the tip is not caught by the base and discharged squarely.

Thus, upon reaching the discharge end, the timing gear 56 stops, the pin 65 stops at the position shown in the drawing, and the rotary lever 64 continues to rotate due to the elasticity of the tension spring 71. The motor stops at the position in contact with the pin 65.

At this time, the distal end portions of the discharge arms 59 and 60 move rapidly to the position indicated by the solid line in the drawing.

As apparent from the above description, according to the present invention, in the binder intermittent release mechanism of the binder, the free end is supported toward the expected axis by a rotating lever that rotates like the rotary shaft provided on the square of the binding mechanism and a support shaft provided on the square of the rotary shaft. By linking the rocking levers connected to each other and constructing a link mechanism, the linking movement is configured to emit the binding valley between the connection and all the discharge arms by the linking movement. After the release, it moves to the oblique forward direction of the base and then returns quickly. It is discharged extremely squarely toward the direction of movement and compares with the conventional Emission performance is remarkably improved.
