Description

[Detailed Description of the Invention] A binding machine attached to a conventional harvesting machine such as a combine harvester has a needle part on one side of a grain culm binding processing passage that supplies, bundles and discharges grain culms, and a binding part and a binding part on the other side. Since it was constructed with a chain case connected to one end of the tying machine, the tying machine became extremely large and heavy, which had the disadvantage of worsening the balance of the harvesting machine and increasing cost.

Therefore, as a result of various studies to improve the above-mentioned drawbacks, the present invention solves the above-mentioned drawbacks by integrating a knot part and a needle part and disposing them on one side of the grain culm binding processing passage. was completed.

However, when the tied grain culm is discharged into the discharge path, the needle part and the knot part are on the same side of the passage, so in the conventional method of feeding the string from the back of the needle, the binding string is then connected to the grain to be fed. Since it is not possible to tie the string across the passage to receive the culm, further research revealed that by providing a string supply port on the other side of the passage facing the collecting culm, the tip of the cord can be secured after the bundle is released. It was possible to set up the grain culm receiving condition by stretching the string, which was fixed to the holder of the knot part, into the passage.

The present invention is small and lightweight, and can be obtained at low cost, yet allows strings to be stretched in the grain culm binding processing passage when releasing bundles, and moreover, the binding device can be attached to a harvester and discharged. Even if the binding device is moved relative to the harvester to change the binding position of the grain culms, the relative positions of the string supply port, nodule, and needle do not change, allowing for accurate binding at all times. The purpose is to provide a binding device for a grain culm binding machine, in which a main body of the binding machine consisting of a knotting part, a needle, etc. is disposed on one side of a grain culm binding processing passage in which a supply path and a culm collection part are connected in series, The needle is provided on the lower side of the knot, and the binding string is supplied to the knot from the upper side, and a string supply port is provided on the other side of the passageway in a part facing the collecting culm, and The present invention is characterized in that the string supply port is connected to the main body of the binding machine, and the main body is mounted so as to be movable and adjustable in the direction of the culm of the grain culm to be supplied to the harvesting machine.

Hereinafter, one embodiment of the present invention and related matters will be described with reference to the drawings.

Next, the transmission device will be explained. The input pulley 20, which is driven by an appropriate shaft of the combine main body, is fixed to a spline shaft 20a supported by the bearing 13 and constantly rotates. The spline shaft 20a is a cylindrical shaft. 21, so when the binding device 4 is moved and adjusted in the culm direction as described later, it expands and contracts while transmitting rotation.

In FIGS. 4 and 5, the transmission mechanism is housed in one transmission case 22 having a case cover 23, and the input shaft 24 is connected to the cylindrical shaft 21 by a pin 24', and the input shaft 24 is loosely fitted onto the input shaft 24. The gear 25 rotates together with the input shaft 24 via a torque limiter.

However, when the trilimiter is not used, the gear 25 is fixed to the input shaft 24.

A gear 27 that meshes with the gear 25 and has a tapered pawl 27a on the side surface is spline-fitted to the crankshaft 26 having the crank pin 26b and the arm cam 26a, and furthermore, the one-turn clutch boss 2

a and 36b, and a hole 35' that slidably holds a clutch pin 36, and a hole 35' that pivotally supports a roller 37 that slides on the cam plate 28a, and the protrusion 29.
A mounting seat 35d having a protrusion 35a that engages with c.
and a boss portion 35c into which a stopper cam 38 is rotatably fitted.
5d fits into the recess 38a and the cam plate 28a.
The stopper cam is provided with two protruding parts 38d and 38e that can come into contact with the arcuate part of the protruding part 28b, and this stopper cam has two protruding parts 38d and 38e that can come into contact with the arcuate part of the protruding part 28b. The tapered hole 38b is biased to be displaced from the clutch pin 36.

Further, the intermediate gear 34 has a gear 4 of a multi-use shaft 40.
1 are in mesh with each other, and a needle 42 and a door 49, which will be described later, are attached to the multi-use shaft 40, and the multi-use shaft 40 serves both as a door shaft and a needle shaft.

Nodule drive mechanism The drive gear 50 consists of 10 teeth in this example,
These teeth are designed to mesh only with the wide tooth 30b of the partially toothed gear 30, and the two teeth, which are out of phase by 180 degrees, have about half of the tooth width cut out to form the partially cut teeth 50a, 50a. ', the drive gear 50 rotates 180 degrees and the cam 30a of the partially toothed gear 30 rotates to the partially partially toothed gear 50a.
Or, when entering the cutout part of 50b, the long teeth 5 in front and behind it
0b, 50b' are locked in sliding contact with the outer periphery of the cam 30a, and when the cam 30a passes through the cutout, the cutout tooth 50a meshes with the wide tooth 30b and is driven. At the same time as the last wide tooth 30b passes the long tooth 50b, the cam 30a enters the cutout tooth 50a', and the drive gear 50 rotates 1/2 and is locked again.

In other words, the toothless gear 30 has 15 teeth, including seven toothless parts, and five of them, 5 wide teeth 30b, rotate the driving gear 50 by 1/2 rotation, and the following gear Since the speed is increased by
During rotation, the bill and holder complete one rotation and perform a knotting action.

Further, the drive gear 50 integrally includes a bevel gear 51 having 18 teeth and is rotatably supported by a shaft 52. The shaft 52 has a small diameter portion 52a at one end and a pin 52c at the other end. A mounting seat 52b screwed onto the transmission case 22 with a mounting bolt is fixed, and the distal end 53a of the anti-reverse claw 53 set on the pin 52c is in pressure contact with the circumferential surface of the cam plate 28a, and the base end The portion is pulled by a tension spring 54 whose one end is locked to the transmission case 22, and the back surface is in contact with an end 55a of a mounting bolt 55. However, protrusion 3
When 5a is engaged with 29c and is acting as a stopper, the anti-reverse claw 53 is separated from the end 55a of the mounting bolt 55, as shown in FIG. 5A.

The speed increasing gear 60 (16 teeth) includes a bevel gear 61 that meshes with the bevel gear 51, and is rotatably supported by a shaft 62, with one end of the shaft 62 connected to the transmission case 22.
The other end is supported by inserting the small diameter portion 52a of the shaft 52 into the hole 62a.

The three-point meshing gear 70 (the number of teeth has no meaning, but it is set to 26) always meshes with the speed increasing gear 60, the holder gear 80 (12 teeth), and the building gear 90 (12 teeth). The shaft 71 is fixed to the transmission case 22 with a nut 72, and a building pressing plate 73 is attached to the outer end of the shaft 71.

Further, the holder gear 80 is attached to a holder shaft 81 that transmits rotation but slides in the axial direction, and the holder shaft 81 is supported by the transmission case 22 via a bush 85,
The holder 84 fixed to the outer periphery of the holder 84 protrudes outside the case, and the holder spring 83 and the holder gear 80 are inserted into the transmission case 22.
It is stored inside.

Further, since a holder spring 83 is interposed between the holder gear 80 and a spring receiver 86 adjusted by a nut 88, the tapered surface of the holder 84 is pressed against the tapered surface of the cam metal 82, and the tapered surface 87 for holding the string is pressed against the tapered surface of the cam metal 82. The spring receiver 8
When adjusting the string clamping pressure by forming the outer end surface of 6 into a hexagonal pyramid-shaped tapered groove and turning the hexagonal nut 88, the nut 88 should match the tapered groove of the spring receiver 86 every 1/6 rotation. The holder spring 83 constantly presses the spring receiver 86, and the nut 8
8 is prevented from returning.

The building 91 itself is exactly the same as the conventional one, but the shaft hole of the building gear 90 is oval-shaped with two parallel surfaces, and the gear bearing portion of the building shaft 91a has a width of the two parallel surfaces as described above. It is formed into an oval shape that is slightly narrower than the shaft hole. In other words, a certain play is formed between the bill gear 90 and the bill shaft 91a.

Further, as shown in FIG. 4, the building pressing plate 73 is pressed against the building 91 by being pulled by a tension spring 92 whose tension can be adjusted by a nut 93.
Since the string clamping pressure is applied to the string 1 and the braking force is also applied, the building 91 rotates in a state deviated in the opposite drive direction by the amount of play described above, as shown by the chain line in FIG. The building gear 9 is pulled to the position shown by the solid line without depending on the rotation of the building gear 90.
0 and the building shaft 91a, but at the same time the spring 92 and the pressing plate 73 are removed.
Returns to the original state of A.

The knot guide 94 has its base fixed to the transmission case 22, and as shown in FIGS. 3 and 5, the knot guide 94 is a grain culm binding processing passage in which the receiving portion 5, the supply path 6, the culm collecting portion 7, etc. are connected in series. Forming one side of A and building 9
The lower end of the string guide port 94c, which is provided diagonally downward from the upper part of the end surface 94d of the knot guide 94, is a dead end, and the entrance part is for the needle to pass through. Part 94a
Furthermore, one side edge serves as a string guide surface 94b.

Drive mechanism for the packer and star wheel In Figs. 3 and 4, a pin 100b is fixed to an arm 100a protruding from the end of the packer shaft 100, and this pin 100b is rod-mounted to a pin 26b that rotates integrally with the crankshaft 26. Since the arm 100a connected by 101 is always swinging, the pack car 102 fixed to the other end swings, and its tip 1
02a moves in an arc between A and B.

The cam link 110 that is in contact with the arm cam 26a that rotates together with the crankshaft 26 is attached to the case cover 2.
The pin 110a provided at the end of the arm cam 26a swings as the arm cam 26a rotates.

The star wheel 114 has a support pin 112c attached to the upper part of the arm 112b which is installed upright on the bearing pipe 112a.
The star wheel 1 is rotatably supported by
A pin 115a at the other end of the link 115, one end of which is rotatably supported by the boss portion 114a of the arm 114, is interlocked with a pin 113d of the arm 113c by a rod 116.
The link 115 in which the pin 113d at the tip of c rises from E to F rotates clockwise to rotate the star wheel 114 by 1/3, and then the pin 113d
When descending from F to E, the base is moved to arm 112b.
Since the stopper 120, which is pivotally supported and biased by the torsion spring 121, receives the tip of the scraping protrusion of the star wheel 114 in a press-contact state, the star wheel 114 does not rotate in the opposite direction, and the pin 119 of the one-way rotation clutch rotates. The star wheel 114 comes out of the inclined groove 114b and fits into the next inclined groove 114b, and eventually the star wheel 114 is driven intermittently by 1/3 rotation in synchronization with the packer 102.

Needle and Door Drive Mechanism In Figures 3 and 4, the boss 42 of the needle 42
a is attached to the tip of the multi-use shaft 40 so as to rotate integrally therewith, and a boss 43 having protruding culm guides 43a, 43a' and stopper arms 43b, 43b is loosely fitted to the multi-use shaft 40 so as to be freely rotatable. There is. Boss 42a
A torsion spring 44 is inserted between the small hole of the boss 43 and the small hole of the boss 43.
A stopper 42b protruding from the boss 42a of the needle 42 toward the base side is located between the culm guides 43a and 43a'.
a' and maintains the posture shown by the solid line in FIG.
When b does not rotate, the needle 42 moves to the frequently used shaft 40.
The needle 42 is configured to be able to rotate approximately 90 degrees from the position shown by the solid line in FIG. 3 to the position shown by the chain line as the needle 42 rotates, as shown in FIG. The part 42, the bundle release action part 42s, the string hooking recesses 42t and 42t', and one claw 42w are made long and curved to cover the other short claw to form a crab claw shape, and formed between them. Strap holder 4
It is composed of 2v etc.

Further, the main part of the door 49 has a hole in the middle part that fits into the stepped part of the boss 43, and one and the other of the main parts have L-shaped receiving parts formed with the main part, Arc-shaped long holes 49a, 49 bored near both ends of the main part
The door 49 is fixed to the stopper arm 43b by screwing a bolt inserted through a' into a screw hole located in the middle of the stopper arm 43b.

Operation timing The crankshaft 26 constantly rotates counterclockwise, and the cam link 11 rotates as the arm cam 26a rotates.
0 rotates and rotates the star wheel 114 by 1/3 turn. During this time, the packer 102 performs a scraping operation, and thereafter descends along the side of the scraping protrusion of the star foil 114. When rising, the cam link 110 is in sliding contact with the arc-shaped portion of the base of the arm cam 26a, so the star foil 114 is not rotationally driven.

During such grain culm raking, while the concentrated grain culm on the door 49 does not reach a predetermined amount, the cushion bar 46, which is pressed upward by the constant pressure spring 47 and supports the stopper 43c, is lowered by a predetermined amount. , the one-turn clutch does not engage and the protrusions 35a and 29c remain engaged, but the constant pressure spring 4
7 reaches a predetermined amount and the multi-purpose shaft 40 rotates (rotates from point O to direction A in FIG. 5A), the swing link 35 moves to C along with the intermediate gear
When the protrusion 35a rotates in the direction, the protrusion 35a engages the clutch plate 29
It comes off from the protrusion 29c.

At this time, the clutch plate 29 rotates because it is biased counterclockwise by the torsion spring 32, and the tapered hole 29b pushes the clutch pin 31. Next, when the police car 102 moves backward, the door 49 and the needle 42 are pushed up by the constant pressure spring 47 and return to their original positions. When the police car 102 descends to the position shown by the solid line in FIG. The tapered pawl 27a is the clutch pin 31.
The timing has come for the one-turn clutch to engage.

In this way, the one-turn clutch is engaged and the cam plate 28a is rotated a (15 degrees in this example) as shown in FIG.
While rotating, the circumferential surface of the cam plate 28a has an arc shape centered on the axis, so it does not push the roller 37, but after that the roller 37 is moved counterclockwise by the cam plate 28a to the position shown in FIG. 5C. During this time, the needle 42 passes through the back side of the wide part at the tip of the packer 102 and wraps the string around the straw bundle, and also passes through the needle passage part 9 of the knot guide 94.
Enter 4a.

In this example, when the cam plate 28a is rotating 80 degrees, the drive gear 50 is rotated by the wide tooth 30b of the partially toothed gear 30.
, and drives the building 91 and the holder 84 at the same time.

Further, while the compressed state is maintained by the packer 102, the building 91 rotates 130 degrees and finishes pulling the string, and when the stop period of the needle 42 ends, the needle 42 is rotated by the rotation of the cam plate 28a (after rotating 120 degrees). 42 begins to return, and at this time the protrusion 28 of the cam plate 28a
b comes into contact with the protrusion 38d of the stopper cam 38, and the roller 37 begins to descend.

When the cam plate 28a rotates 130 degrees, the protrusion 38e of the stopper cam 38 touches the protrusion 2 of the cam plate 28a.
8b abut against each other to prevent the stopper cam 38 from rotating. At this time, the narrow teeth 30c of the partially toothed gear 30 and the intermediate gear 34 are in mesh with each other, so the torsion spring 39 is further twisted and the clutch pin 36 is rotated at its tapered portion 36a. is pushed out by the tapered hole 34a of the intermediate gear 34, and its end surface rides on the plate surface of the intermediate gear 34, and the other tapered portion 36b fits into the tapered hole 38b of the stopper cam 38, and the intermediate gear 34 and the swing link 35 are mutually separated. Becomes free.

At this time, the cam plate 28a has rotated 195 degrees,
The needle 42 returns to the O point, and thereafter the intermediate gear 34
is driven by the partially toothed gear 30, so the needle 4
2 starts to release the bundled grain culm, which will be described later, from point O by the discharge action portion of the needle 42 located at the lower side as shown in FIG.

During that time, when the cam plate 28a rotates 165 degrees, Bill 91 catches the string in its beak, and immediately after that, the knife of the holder 84 cuts the string, and when the rotation angle of the cam plate 28a reaches 205 degrees, Bill 91 catches the string in its beak. 91 and the holder 84 rotate once, and the cutout tooth 50a' is locked by the cam 30a of the cutout gear 30 and stops. When the rotation angle of the cam plate 28a becomes approximately 212 degrees, the needle 42 is placed at the rear. Knotting is performed by pushing out the bundled grain culm by the discharge action portion 42s', and then, when the rotation angle of the cam plate 28a reaches 240°, the star wheel 114 is activated.

The needle 42 continues to rotate further and the cam plate 28a
The rotation angle becomes 345° and it stops. At that time, the protrusion 35a of the swing link 35, which was rotating together with the intermediate gear 34, receives the protrusion 29c of the clutch plate 29 and rotates the clutch plate 29 in the opposite direction relative to the cam plate 28a, thereby shifting the taper pawl 27.
Clutch pin 31 which was under pressure by a
is fitted into the tapered hole 29b of the clutch plate 29, and the one-turn clutch is disengaged.

Next, the operation of each part will be explained in more detail.

Relationship between the return of the needle 42 and the trouser car 102 Figure 5 K and Figure 8 C show the needle 42 turning towards the building 91 to wrap the string and then returning to the standby position (the position shown by the solid line in Figure 3) This indicates the moment when the cam plate 28a passes through the O point.
This shows the point in time when the needle 42 has rotated 195 degrees, and the needle 42 is thereby driven further 180 degrees together with the culm guide 43a, door 49, etc., and during this time, the door 49 and the discharge action section 42s' of the needle 42 are used to perform the knot cutting and the needle 42. Performs a releasing action.

Grain culm supply and bundle release In Figure 5 H, Figure 9 O, Figure 8 C, and Figure 6, when the rotation angle of the cam plate 28a reaches 205 degrees, the building 91 and holder 84 stop, and the needle 42 is released. The acting portion 42s' and the door 49 begin to push out the bundle, and the state as shown in FIG. is driven.

Needle stop and one-turn clutch intermittent timing The needle 42 is connected to the wide tooth 3 at the end of the partially toothed gear 30.
When 0b finishes driving the intermediate gear 34, the cam plate 2
8a has rotated 345 degrees (15 degrees before returning to point O) as described above, and at this time, the protrusion 35 of the swing link 35
a comes into contact with the protrusion 29c of the clutch plate 29, so when the cam plate 28a further rotates 15 degrees with respect to the clutch plate 29, the clutch pin 31 moves into the tapered hole 29b.
The clutch disengages one turn.

Culm guide, door, and constant pressure spring Culm guides 43a, 43a' and door 49 are door 49
The stopper arm 43c is screwed onto the stopper arm 43b so that the stopper arm 43c is integrated with the stopper arm 43b.
Alternatively, the culm guide 43a or 43a' is supported by a cushion bar 46 which is supported by a constant pressure spring 47 via 43c'. This prevents the bundle from acting as resistance when acting.

In addition to operating the one-turn clutch, the door 49 also has the function of holding the bundle against packer pressure via a constant pressure spring 47 to improve the tightness of the bundle. 42
The collecting culm part 7 is held while the string returns to point O shown by the solid line after the stringing, but when the bundle is released thereafter, the needle 42 and the door 4 are moved as shown in Fig. 8 C, A, and C.
9 rotate together to open the discharge path 8.

Immediately before the needle 42 rotates 180 degrees from point O and stops, the stopper 43c or 43c' rides on the head while tilting the cushion bar 46 and stops.

Drive and connection of bill and holder Bill 91 and holder 84 are three-point mesh gear 70
simultaneously driven by.

Conventionally, the holder is driven after the building placed in the position shown in Fig. 9 K starts to rotate, and even after the building stops, only the holder rotates and stops at the position shown in the figure, and the bundle release direction is not the same as that shown in Fig. 9 K. Since the bill must be in the direction shown in the figure in order to face downward and remove the knots, the holder 84 closes the bill and grasps the string that was latched before and the string that was supplied by the needle from behind. In order to do this, it must be done immediately before the building stops, which causes the string to remain and the subsequent string holding function deteriorates, and furthermore, when the building grabs the string, the string that has been locked to the second protrusion x comes off. Three knots due to loops being pulled out, one-sided knots, and complete mistakes were occurring.

However, the one with this structure is shown in Fig.
02, but in this figure, the nodule guide 94
Needle 4 as shown in (extended at 90 degrees)
2 hangs a string and releases the bundle in the direction of retreat. That is, the knot removal direction is the needle retraction direction, and the upper string guide groove 94c is made a dead end, so that the knot guide 94 can move the bill 91 as shown in FIGS. 9A and 9B.
The string guide groove 94c of the needle 42 can be diagonally crossed and stopped in an open state facing the direction in which the needle 42 enters.
The cord can be inserted into the opening securely without getting caught on the tip of the cord, and the cord gripping position can be moved forward from the knot removal position (Fig. 9 C).
Since the string that is firmly locked in the dead end portion of the string guide groove 94c is held in place, the string can be reliably removed during the period from E to E, and there is no chance of making a mistake in grabbing the string.

In addition, since the looseness is provided between the bill 91 and the bill shaft 91a as described above during pruning, the bundle is moved by the discharge action portion 42s' of the needle 42 acting as a discharge arm and the door 49. When pushed out, the building 91 rotates from the position shown by the chain line to the position shown by the solid line in FIG. Therefore, return to the position indicated by the chain line.

Supplying a string to the needle This needle 42 does not have a so-called string passing hole as in the conventional case, and the string receiving portion 42v at the tip is opened in the shape of a crab claw or 10 arms as described above. When the bundle is released, it separates from the string.

Therefore, the annular string supply port 14 is connected to the shaft of the needle 42 as described above, in order to supply the string to the needle 42 rising from below when releasing the bundle, and to receive the grain culm supplied after the release with the string. The needle 42 is attached to the boss 15a of the guide 15 on the opposite side of the passageway and diagonally crosses the rotation locus of the string receiver 42v of the needle 42 (FIG. 8, F'). While the needle is rotating toward the standby position (the upper position shown by the solid line in FIG. 3), guide the string that is diagonally stretched across the needle arc-shaped portion 42r' in the plane shown by the chain line in FIG. Finally, it enters the string receiving part 42v' and becomes the state shown in FIG. 8F.

Further, when the string is wound by the needle 42, the needle 42 guides the string pulled out from the string supply port 14 to the opposite side of the building 91 and the holder 84 as shown in FIG. The string on the supply port 14 side never gets caught on the building 91 or the like, and one of the long claws forming the string receiving part 42v is bent to cover the tip of the short claw, so that the needle 42 Coupled with the fact that the string receiving part 42v passes through the back of the packer 102, when the string is hung, the grain culm does not enter the string receiving part 42v and cause a bundling error.

Mounting part of the bundling device The frame 9 has the upper and lower pipes 9c′,
9c'', pillars 9a, 9b, etc., and the lower pipe 9c'' is integrally protruded with a base 10a having a long hole 10d, and a mounting portion 10 consisting of a pair of supporting metals 10b, 10b', etc. , said bracket 1
Reference numeral 12 includes a window 112e through which the pressing part 128c at the upper part of the fixed plate 128 faces, a mounting hole 112d for screwing the transmission case 22, and a pair of support holes 112f and 112f' drilled at the lower part of both sides. .
