Description

[Detailed description of the invention] The packer in the conventional stalk culm binding machine is fed by a grain culm feeder and placed in the supply path leading to the culm collecting section, and is inserted into the continuous grain culm. Since the grain culms are gathered into the collecting part, when the grain culms come into contact with the tip of the culm and are bent, or when the culm is inherited by the grain culm feeder,
Since the tip of the packer forcibly pushes apart the intertwined grain culms, the grain culms become extremely disordered and bundled, resulting in a drawback that good binding cannot be achieved.

This invention clearly separates only the grain culm sent by the raking protrusion of the grain culm sending body from the following grain culm behind the raking protrusion, and rakes it into the culm collecting part by the pucker, so that it is placed at the tip of the culm. Therefore, it is an object of the present invention to provide a grain culm insertion device in a stalk culm binding machine that can scrape and bundle grains into a culm collection part without bending the grain culms or disturbing the posture of the grain culms, A grain culm feeding body having a raking protrusion is provided on the side of the supply path toward the culm collecting part in close proximity to the pucker, and the culm feeding body is arranged so that the raking protrusion crosses the supply path along the raking locus of the culm car. The pucker and the grain culm feeding body are arranged such that the raking locus of the tip of the pucking car extends within the width of the raking protrusion of the grain culm feeding body when viewed from the direction of the culm of the grain culm to be fed. It is characterized by being disposed so as to pass along the direction and being interlocked.

The grain culm scraper in the present invention is exemplified as a star foil 114 in the embodiments described later.

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

One side of the tying device is formed into a grain culm tying processing passage A which is a series of a receiving section 5, a supply path 6, a culm collection section 7, and a discharge path 8 in order from the starting end, and a knot section and a needle section of the tying device. Both are the grain culm bundling processing passage A.
It is located on one side of the.

Next, to explain the transmission device, the input pulley 20 is driven by an appropriate shaft of the combine main body, and is fixed to a spline shaft supported by a bearing and constantly rotates.
1 is spline-fitted, so when the binding device is moved and adjusted in the culm direction as described later, it expands and contracts while transmitting rotation.

In Figs. 2 to 4, 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 into 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 onto the crankshaft 26 having a crank pin 26b and an arm cam 26a, and a one-turn clutch boss 28
is rotatably fitted. The one-turn clutch boss 28 has a crescent-shaped protrusion 28b and a pin 2 at one end.
A cam plate 28a having a diameter of 8c is provided, and a partially toothed gear 30 is provided on the other side with a loosely fitted clutch plate 29 sandwiched therebetween.
The partially toothed gear 30 and the clutch plate 29 are connected to each other by spline fitting, and the ends thereof are formed by small holes 29d and 3.
The clutch plate 29 is urged in the rotational direction (counterclockwise in FIG. 4) in conjunction with a torsion spring 32 that is locked at 0d.

Numeral 31 is a clutch pin having tapered portions 31a and 31b at both ends, and is loosely fitted into a hole 28a' formed in the cam plate 28a.
has a protrusion 29c, a tapered hole 29b into which the tapered portion 31b of the clutch pin 31 fits, and a recessed portion 29a in which the pin 28c engages to regulate the rotation angle of the clutch plate 29 relative to the cam plate 28a. As shown in FIG. 3C, the gear 30 is integrally provided with a flange-shaped cam 30a with a part (wide tooth 30b portion) cut out, and the teeth have five wide teeth 30b.
It is made up of three narrow teeth 30c, making up seven missing teeth.

The forward/reverse shaft 33 has one end that meshes with the wide teeth 30b and the narrow teeth 30c of the partially toothed gear 30, and has tapered holes 34a, 34b, 34c, 34 spaced at 90° intervals.
d has a bored intermediate gear 34 (24 teeth), and a swing link 35 is loosely fitted on the other side, and the swing link 35 has tapered portions 36 on both sides.
a, 36b and a hole 35' which slidably holds a crank pin 36, and a hole 35' which 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 38 is provided with two protrusions 38d and 38e that can come into contact with the arcuate portion of the protrusion 28b, and this stopper cam 38 is provided with a torsion spring 39 whose both ends are engaged with small holes 38c and 35b, as shown in FIG. 3A. The tapered hole 38b is biased so as to be displaced with respect to 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 the cam 50b enters the cutout, the front and rear long teeth 50b, 50b' slide into contact with the outer periphery of the cam 30a and are locked, 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 cam 30a passes the last wide tooth 30b or 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 the drive gear 50 is rotated by 1/2 rotation by five of the wide teeth 30b.
The speed is increased by the succeeding gear, so that the bill and holder make one revolution while the partially toothed gear 30, which is the output gear of the one-turn clutch, makes one 5/15 revolution to perform the connecting 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 having a small diameter portion 52a at one end,
A mounting seat 52b having a pin 52c and screwed onto the transmission case 22 with a mounting bolt is fixed to the other end, and the tip 53a of the anti-reverse gourd 53 set on the pin 52c is attached to the periphery of the cam plate 28a. The base end is pulled by a tension spring 54 whose one end is fixed to the transmission case 22, and the back surface is in contact with an end 55a of a mounting bolt 55. However, when the protrusion 35a engages with the stopper 29c, the anti-reverse claw 53 is separated from the end 55a of the mounting bolt 55, as shown in FIG. 3A.

The speed increasing gear 60 (several teeth) includes a bevel gear 61 that meshes with the bevel gear 51, and is rotatably supported by a shaft 62. One end of the shaft 62 is attached to the transmission case 22, and the other end is fitted with a hole. The small diameter portion 5 of the shaft 52 is located at 62a.
It is supported by inserting 2a.

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 and is also inserted into the cam metal 82. Only the holder 84 fixed to the outer end of the holder 84 protrudes outside the case, and the holder spring 83 and the holder gear 80 are housed inside the transmission case 22.

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. 2, the building pressing plate 73 is pressed against the building 91 by being pulled by a tension spring whose tension can be adjusted by a nut, thereby applying cord clamping pressure to the building 91 and applying a braking force. Therefore, the bill 91 rotates with an angle deviated in the counter-driving direction by the amount of the play, and when the knot is removed, it is pulled by the tied string and reaches the position shown by the solid line without depending on the rotation of the bill gear 90 and the bill gear 90 and the bill shaft. The spring 91a rotates by the amount of play caused by fitting, etc., but the spring 92 rotates at the same time as the knot is removed.
And the press plate 73 returns to the original state.

The nodule guide 94 has its base fixed to the transmission case 22, and as shown in FIG. It also prevents the grain culm from coming into contact with the building 91 and the holder 84.

Drive mechanism of the pack car and star wheel In FIGS. 2 and 7, the pack car shaft 100
A pin 100 is attached to the arm 100a protruding from the end of the
b is fixed, and this pin 100b is connected to the crankshaft 26
Since the arm 100a is connected by a rod 101 to a pin 26b that rotates integrally with the arm 100a, the arm 100a is constantly oscillated, so the packer 102 fixed to the other end oscillates, and its tip 102a 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 between C and D as the arm cam 26a rotates.

Also, the bracket 1 that holds the transmission case 22
The intermediate shaft 11 is attached to the bearing pipe 112a provided in the bearing pipe 12.
3 is rotatably inserted through the intermediate shaft 113.
Pin 1 at the tip of arm 113a fixed at one end
13b is the pin 110a of the cam link 110;
Since they are connected by a link 110b, the intermediate shaft 113 reciprocates within a certain angle, and an arm 113c having a pin 113d at the tip is fixed to the other end of the intermediate shaft 113, as shown in FIG. There is.

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 connected to the pin 113d of the arm 113c by a rod 116.
is linked to.

Further, a torsion spring 117 is interposed between the arms 112b and 113c so that the cam link 110 is constantly pressed against the arm cam 26a, and the link 115 is biased downward, and is held by the boss portion of the link 115. The stopper pin 119 is attached to the star foil 11 via the spring 118 as shown in FIG.
4, the inclined groove 11 is provided on the plate surface of the star foil 114 and is gradually shallower on the rear side in the direction of rotation.
A one-way rotating clutch is formed by press-fitting the head of the stopper pin 119 into the first
In the figure, pin 113d at the tip of arm 113c
As the link 115 rises from E to F, it rotates clockwise to rotate the star wheel 114 by 1/3, and then when the pin 113d moves down from F to E,
A stopper 120' whose base is pivoted to the arm 112b and biased by a torsion spring 117a.
The star wheel 114 does not rotate in the opposite direction, and the pin 119 of the one-way rotation clutch slips out of the inclined groove 114b and moves into the next inclined groove 11.
4b, and eventually the star wheel 114 is driven intermittently by 1/3 rotation in synchronization with the police car 102.

Needle and Door Drive Mechanism In Figures 1 and 2, 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. . Boss 42a
A torsion spring 44 is set between the small hole of the needle 42 and the small hole of the boss, and the stopper 42b protruding from the boss 42a of the needle 42 toward the base side is connected to the culm guide 43
a and 43a', abuts against the culm guide 43a', and maintains the posture shown by the solid line in FIG.
With the culm guide 43a and the stopper arm 43b not rotating, the needle 42 can rotate approximately 90 degrees from the position shown by the solid line in FIG. 1 to the position shown by the chain line as the multi-purpose shaft 40 rotates. As shown in FIG. 1 when viewed from the side, the needles 42 have arcuate parts 42r, 42r' bundle release action part 4 (in this example, they are a pair, but one or three may be used).
2s, 42s string hanging recesses 42t, 42t' and string receivers 42v, 42v formed between the two by making one claw 42w long and curved to cover the other short claw to form a crab claw shape. When viewed from above, the string receiving part 42v at the tip is inclined so as to face the position of the needle passage part 94a of the nodule guide 94, and the culm guides 43a, 4
3a rotates along the end surface 94d of the knot guide 94.

Further, the main part of the door 49 has a hole in the middle part that fits into the stepped part of the boss, and one side and the other of the main part are formed with L-shaped receiving parts. The door 49 is fixed to the stopper arm 43b by screwing bolts inserted into arc-shaped long holes 49a, 49a' drilled near both ends of the door into a screw hole located in the middle of the stopper arm 43b. By adjusting the mounting angle within the range of the elongated holes 49a and 49a', the width of the culm collecting portion 7 can be changed and the size of the bundle can be adjusted.

Operation timing The crankshaft 26 constantly rotates counterclockwise in FIG. 7, and the cam link 110 rotates from C to D when the arm cam 26a rotates from the position shown by the solid line to the position shown by the two-dot chain line. , star foil 1
Turn 14 1/3 turn. During this time, Police Car 102
The tip reaches point A from the position indicated by the solid line, returns to the position indicated by the solid line, and then descends along the side of the scraping protrusion of the star foil 114, and as it rises, the cam link 110 touches the arc-shaped portion at the base of the arm cam 26a. Since the star wheel 114 is in sliding contact with the star wheel 114, the star wheel 114 is not driven to rotate. In other words, the tip of the packer 102 passes between the front and rear grain culms partitioned by the raking protrusions of the star wheel 114 in any stroke of reciprocating rotation.
The grain culms to be supplied are neatly divided and raked toward the door 49 in an orderly manner, and the star foil 114 cooperates with the guide 15 to deliver them to the pack car 102 without leaving any grain deep inside the supply channel 6.

During such grain culm raking, while the concentrated grain culm on the door 49 does not reach a predetermined amount, the amount of descent of the cushion bar 46 which is pressed upward by the constant pressure spring 47 and supports the stopper 43c, that is, the constant pressure spring 4
Since the amount of compression of the constant pressure spring 47 has not reached the predetermined amount, the one-turn clutch does not engage, and the engagement state of the protrusions 35a and 29c is maintained. When the swing link 35 rotates together with the intermediate gear 34 in the direction C (15 degrees in this example) due to rotation (rotation from point O to direction A in FIG. 3A), the protrusion 35a 29
It comes off from the protrusion 29c.

At that time, the clutch plate 29 is attached to the torsion spring 3.
2 in the counterclockwise direction in FIG. 3, it rotates, 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. taper claw 27
The timing is such that the clutch a contacts the clutch pin 31 and the one-turn clutch is engaged.

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. 3C. 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.

At this time, the needle 42 is 5 degrees before completion of string winding (Fig. 3 C), the packer 102 is 21 degrees before the maximum compression, and the cam plate 28a has rotated 85 degrees.
Between 38° and 123°, the guide surface of the cam plate 28a is an arc centered on the axis, so the needle 42
is inserted the most and is stopped until it reaches O in Fig. 3 with the holder 84 being held firmly and the string is attached.
PATSUCAR 102 continues to compress, while building 91
is driven approximately 63°.

That is, by stringing the grain culm while compressing it with the packer 102, it is possible to firmly bind the grain culm.

Moreover, even after the maximum compression point, the packer 102 is still being driven by the crank motion of the arm 26a and is near the bottom dead center, so the amount of return of the packer 102 is extremely small.

That is, while maintaining the compressed state, the building 91
The string rotates 130 degrees and finishes pulling the string, so it will not loosen and will be tightened firmly.

Then, when the stop period of the needle 42 ends, the needle 42 begins to return due to the rotation of the cam plate 28a (after rotating 120 degrees) (Fig. 3 O), and at this time, the cam plate 28a
The protrusion 28b of a is the protrusion 3 of the stopper cam 38.
8b, and the roller 37 starts to descend, so that the teeth of the partially toothed gear 30 and the intermediate gear 34, whose relative positions are regulated, start to mesh smoothly without colliding with each other. Figure O is just before engagement).

When the cam plate 28a rotates 130 degrees, the protrusion 28b of the cam plate 28a comes into contact with the protrusion 38e of the stopper cam 38, as shown in FIG. Since the teeth 30c and the intermediate gear 34 are in mesh with each other, the torsion spring 39 is further twisted into the state shown in FIG.
is pushed out by the tapered hole 34a of the intermediate gear 34, and the end surface rides on the plate surface of the intermediate gear 34,
Since the other tapered portion 36b is fitted into the tapered hole 38b of the stopper cam 38, the intermediate gear 34 and the swing link 35 are free from each other (the state shown in FIG. 3G).

At this time, the cam plate 28a has rotated 195 degrees,
The needle 102 returns to the O point, and thereafter the intermediate gear 3
4 is driven by the partially toothed gear 30, the needle 42 starts discharging the bundled grain culm from point O using the discharge action portion 42 of the needle 42, which has the bundled grain culm below it, which will be described later.

During that time, when the cam plate 28a rotates 5 degrees, that is, during the clutch switching action by the clutch pin 36, the bill 91 catches the string in its beak.
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, the bill 91 and the holder 84 rotate once, and the cutout tooth 50
a' is locked and stopped by the cam 30a of the partially toothed gear 30, and when the rotation angle of the cam plate 28a becomes approximately 212 degrees inward or outward, the rear needle 42 is moved to the discharge action part 42.
Knotting is performed by pushing out the bundled grain culm, and then the rotation angle of the cam plate 28a is set to 240°.
゜, the star wheel 114 is activated.

The needle 42 continues to rotate further and stops when the rotation angle of the cam plate 28a reaches 345 degrees. At this 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 clutch plate 29 to the tapered pawl 27a. As a result, the clutch pin 31, which has been subjected to the pressing force, matches and fits 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.

String pinching and cutting When the cam plate 28a rotates 5 degrees, the building 91 pinches the string, and when the clutch plate 28a rotates 170 degrees, the previously pinched string is separated from the holder 84, and the new string is held in the holder 84. It will be cut off along with.

The relationship between the return of the needle 42 and the trouser car 102 is shown in Fig. 3K. After the needle 42 rotates toward the building 91 to wrap the string, it returns to the standby position (the position indicated by the solid line in Fig. 1) at point O. This shows the moment when the cam plate 28a has rotated 195 degrees, and the needle 42 is integrated with the culm guide 43a, door 49, etc.
During this time, the door 49 and the ejecting portion 42 of the needle 42 perform the cutting and ejecting operations.

Grain culm supply and bundle release In Figures 3 and 6, when the rotation angle of the cam plate 28a reaches 205 degrees, the building 91 and the holder 84 stop, and the release action part 42 of the needle 42 and the door 4
9 begins to push out the bundle, and then the bundle jumps out from the collecting culm 7 and enters the discharge state, and only at this time does the star wheel 114 drive.

That is, the one-turn clutch is driven and the cam plate 28
While a rotates 240°, the star foil 114 holds the trailing grain culm and clearly separates the front and rear grain culms,
This prevents the subsequent grain culms from being taken out due to release.

Needle stop and one-turn clutch intermittent time 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.

The building 91 and the holder 84 are the three-point meshing gear 70
The needles 42 are simultaneously driven by the needles 42 and eject the bundle in the retracting direction.

As mentioned above, the present invention is a stalk tying machine equipped with a needle, a knot part, a culm collecting part, and a packer, and a grain culm feeding body having a scraping protrusion is provided on the side of the supply path toward the culm collecting part. , installed close to the police car,
The raking protrusion is configured to cross the supply path along the raking locus of the pucker, and the pucker and the grain culm feeding body are arranged so that the raking locus of the tip of the pucker is aligned with the grain culm to be fed. When viewed from the culm direction, the raking projections of the grain culm feeding body are disposed so as to pass within the width thereof along the length direction thereof and are interlocked, so that the raking projections of the grain culm feeding body When the grain culm that has been fed is raked by the packer toward the culm collecting section, the tip of the raker crosses the supply channel and the grain culm pushed in with its front surface, and the subsequent grain culm received with its back surface. When the patrol car enters and crosses the supply route, it bends the grain culm at its tip, or it disturbs its posture by forcing its way through the grain culms that are continuously fed in an intertwined state. It can be gathered and tied in an orderly manner without sagging.

Moreover, since the packer scrapes the grain culm that has been divided by the scraping protrusion of the grain culm feeder, the grain culm can be transferred smoothly from the grain culm feeder to the packer.
