Abstract

PURPOSE:To prevent damage to mat rashes by attaching and fixing a cushioning film to a plane of action of a curved guide belt in contact with the mat rashes so that the cushioning film may stretch out from the curved guide belt itself by prescribed amounts. CONSTITUTION:In a lower step position of an inner nip belt 88 for nipping the head side of mat rashes, a curved mat rash-guide belt 126 is arranged in parallel so that the guide belt may move together with the nip belt 88 in a body in the same direction. A cushioning film 144 are attached and fixed to a plane of action of the curved mat rash-guide belt 126 in contact with the mat rashes so that the film may stretch out to the lower side or both the upper and lower sides from the belt 126 itself by prescribed amounts 13 and 14. Damage to the mat rashes can be entirely prevented therefor and there is no danger of slipping during conveyance. In addition, however large or small the degree of curvature of the mat rashes may be changed, the cushioning film 144 can freely adapt itself to the change so as to entirely prevent resistance or damage thereto during conveyance.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a clamping and conveying mechanism for cut rushes in a rush harvester.

<Prior art> The present applicant previously published Japanese Patent Publication No. 62-24043 and No. 63-
No. 51647, while holding the tips of the harvested rushes and lifting them to the rear of the machine, the stem side of the rushes is moved laterally to the left and right of the machine, so that the entire rush can be harvested at the beginning of the harvest. We proposed a method of bending the aircraft from an upright position to a sideways position, swinging it up to the top of the aircraft, and then tying it up on the top of the aircraft while lying on its side.

Then, after that, a third party proposed JP-A-1-25.
No. 2217 also has a method for treating cut rushes that is similar to the above-mentioned known invention of the present applicant. However, in this case, a round bar-shaped clamping guide (1
9) is fixedly installed.

<Problems to be Solved by the Invention> However, according to such a fixed holding guide (19), regardless of its shape such as a round bar or an L-shaped plate piece,
This causes the middle parts of the rush to rub against each other, damaging the rush and making it impossible to harvest it as a high-quality, shiny product.

In addition, while the tip of the rush is conveyed to the rear of the machine by the rotating movement of the clamping and conveying device (9), the clamping guide (19) facing the lower position does not move at all, so that the rush is not moved at all. Due to the frictional resistance between the midway portion and the holding guide (19), the midway portion is inevitably transported later than the tip side.

As a result, the rushes are more and more severely damaged, and the rushes are also misaligned when being transported backwards.
Not only does it tend to fall off easily, but it also makes it impossible to lay it down smoothly and in an orderly manner, as it tends to turn it over onto its side. Such problems become more prominent as the amount of rushes processed increases in two-row mowing.

<Means for Solving the Problems> The present invention is intended to improve the above-mentioned problems, and for this purpose, an endless rush gripping belt is connected vertically to a pair of pulley shafts in the front and rear, which are installed on the machine body. While being able to freely circulate around the axis and stirring the inner and outer positions in a parallel state, the tip side of the harvested rush held between the back-to-back surfaces of both of the holding belts is lifted and conveyed to the rear of the machine, During the rearward conveyance action, the rush is designed to be turned sideways into a curved state by swinging the stem end of the rush inward toward the inside of the aircraft. In particular, in the grass harvesting machine, a rush bending guiding belt, which serves as a movable fulcrum for inwardly bending the rushes clamped on the back-to-back surfaces thereof, is installed at a lower position of the inner clamping belt integrally with the clamping belt. The belt is supported in parallel so that it can move around in the same direction, and a cushion film is provided on the working surface of the belt that comes into contact with the rush, so that only the lower end or both the upper and lower ends are more constant than the belt itself. The first feature is that the rushes are attached and fixed in a relational state in which they are extended by the amount, and furthermore, assuming the same rush harvesting machine as above, rushes are introduced into the back-to-back surfaces, especially at the lower position of the inner clamping belt. Two kinds of rush pulling belts and rush bending guiding belts, which serve as movable fulcrums for inwardly bending the drawn and clamped rushes, are both integrally rotated in the same direction as the clamping belt. In addition to supporting it in parallel so that it can run, shoes/shoes are installed on the working surface of the curved guiding belt that comes into contact with the rushes.
The second feature is that the connecting membrane is attached and fixed in such a manner that only its lower end or both its upper and lower ends protrude by a certain amount beyond the curve guiding belt itself.

<Function> According to the first configuration, the rush curved rust guiding belt is provided at the lower position of the inner clamping belt (88) that clamps the tip side of the rush.
(126) is installed in parallel with the clamping belt (88) so that it can integrally run in the same direction, so there is no conveyance resistance to the rushes that come into contact with it.
The rushes will be transported in a well-ordered and orderly manner, and as soon as the stem side of the rushes is subjected to the cross-feeding action of the waste extraction and sorting mechanism (E), the machine body It is automatically and smoothly turned inward, and its overall curved state is maintained.

Moreover, a cushion film (144) is provided on the working surface of the rush curve guiding belt (126) that comes into contact with the rushes.
26) A certain amount (L3) from itself downward or both upward and downward.
L4) is attached and fixed in a state where only L4) is overhanging, so there is no damage to the rush, no slippage during transport, and no matter how large or small the degree of curvature of the rush changes. The cushion film (144) freely adapts to this, and there is no risk of resistance or damage during transportation.

Further, according to the second configuration, the inner clamping belt (88
In addition to the two rush grass curve guide belts (126) at the lower position of ), the two clamping belts (88) and (89) are placed back to back, and the retraction belt (145) that introduces the rush tip side
) are also installed in parallel so that they can integrally rotate in the same direction as the inner clamping belt (88), so in addition to being expected to have the effect associated with the first configuration, its curvature The retraction action that precedes the action of changing the direction of rushes by the guide belt (126) can also be achieved reliably and with good stability.

<Example> Hereinafter, the specific structure of the present invention will be described in detail based on the illustrated example. Figures 1 to 7 show a riding-type rush harvester for cutting two rows of rushes and its overall operation. , (10) is a general term for the aircraft, which includes a fixed track frame (11),

In other words, the horizontal frame (14) on the left side (uncut side) is extended forward longer than the horizontal bar (15) on the right side (already cut side), and the front end of the horizontal frame (14) has an outer chain case (described later). The supporting front inclined support column (16) is fixed in an upright position in a rear-hinged position. (17) is the same long horizontal frame (14

Then, the rear end portions of both the horizontal frames (14) and (15) are connected to the left and right end portions of the track frame (11) on the horizontal horizontal axis (
The front frame (13) is pivotally connected via the front frame (13).

12) is horizontally mounted at a position offset rearward by a fixed distance (Ll) from the horizontal axis (22) which forms the rotational fulcrum.

(31) is a pair of left and right endless running crawlers 1 (32) which are rotated by the power taken out from the transmission (26), and are located at the front of the truck frame (11), while the engine (25) The rush binding bed (33) that completely covers the upper surface is attached to the transmission (26) and intermediate shaft (27) following the binding bed (32).
This is the main deck for loading rush bundles that covers the entire upper surface of rush bundles (M ) can be accommodated and loaded.

(34) is the main deck (
This is a driver's cab that is integrally extended from 33) to the rear, and while the operator rides on this cab, it interferes with the loading of rush bundles (M) on the main deck (33) located just before it. It is also easy to extend the operator to the rush bunch (M) and correct any disturbances.

Although the illustrated embodiment represents a riding-type harvester,
As long as the above purpose can be achieved, the present invention can be applied to a type of rush harvester in which the operator operates a hand pusher while walking in the field.

(35) is a vertical line extending in a relational plane orthogonal to the horizontal axis (22) at tθ at the canvas side (already cut side) end of the continuous main deck (33) and driver's cab (34). Axis (3

It is integrated into a frame in the shape of a letter, and its interior is open to communicate with the interior of the main deck (33).

As suggested from Fig. 5, rush bundles (M) are laid down inside the main deck (33) in a state of extension along the left and right direction of the fuselage (10).
Inside the sub-deck (35), rush bundles (M) are placed in a state of extension along the longitudinal direction of the machine body (10), and the amount can be increased for cutting two rows of rushes. It looks like this.

By appropriately selecting the rotation angle, the loading capacity and stability of the rush bundle (M) can be adjusted, and by lowering the rush bundle (M) downward, the rush bundle (M) can be moved into the aircraft (10).
When placed on the right side (already cut side) of the field, it can be easily unloaded onto the field.

(39) is a temporary support device for the tied rushes (M), which is interposed as a pair on the left and right at the boundary between the bundling floor (32) and the main deck (33). The tip side and the base side of the rush bunch (M) are temporarily moored in a stable state as shown in Fig. 7. By temporarily mooring one bundle, the main deck (33
), the rush bundles (M) are efficiently and stably transferred to the main deck (33) and, after the main deck (33) is fully loaded, to the sub-deck (35), as intended by the operator. It can be loaded well.

(40) is a series of working mechanisms (A) to (G) mentioned earlier.
This is a primary power distribution shaft for inputting working power to the work frame (12), and is supported at a position biased to the left side (uncut side) of the work frame (12). This primary power distribution shaft (40)
．． As is clear from the side view in Figure 9, the front view in Figure 10, and the plan view in Figure 11, it is horizontally suspended parallel to the horizontal horizontal axis (22) and intermediate axis (27), Moreover, they are arranged at a position forward of the horizontal axis (22).

The primary power distribution shaft (40) and the intermediate shaft (2)
7) is electrically connected between the front and rear via a relatively long endless third transmission belt (41), which is why it is mounted on the truck frame (11)! - The primary power distribution shaft (40) is rotationally driven by the engine (25). (42) (43) is a hanging pulley for the third power transmission belt (41), but as suggested from Figures 1 and 11, its intermediate shaft (18)
Primary power distribution shaft (40) than the upper pulley (42)
Pulley (43) assembled on the outer (left side) shaft end of
This one has a considerably larger diameter and is able to slow down the performance.

(44) is inside (right side) of the above primary power distribution shaft (40)
The first bevel gear mechanism is assembled and integrated with the shaft end (this is indicated by a gear case in the figure, and the same applies to the second to eighth bevel gear mechanisms described later), and from now on, As shown in Fig. 10, the first power transmission shaft (45) stands up toward the upper tip-side pinching and conveying mechanism (C), and the stock-base side converging conveyance mechanism (F) also located on the right side (already cut side). ) and a second power transmission shaft (46) horizontally suspended toward the binding mechanism (G), each of which is arranged in an array.

Also, a working transmission mechanism (47) is also interposed at the intermediate position of the primary power distribution shaft (40), and from the upper stage there is a waste sorting mechanism (E) located on the right side.
The third transmission shaft (48) that extends toward the left side (
Non-mowing side) position - The fourth transmission shaft (49), which serves as the weeding mechanism (A), the pulling mechanism (B), and the reaping mechanism (D), is its primary power distribution shaft. (40) The distribution is suspended parallel to itself.

In other words, the work frame (12) forming the front part of the aircraft (10)
) A series of working mechanisms arranged centrally on top (A) ~
(G) is driven by the engine (25) mounted on the truck frame (11), which also forms the rear part of the fuselage (10), through the primary power distribution shaft (40), and each of them is given a predetermined effect. It has come to be run as a business.

At this time, the belt tension roller (50) that contacts the third transmission belt (41) from below is mounted on the fixed track frame (11) side, and the work frame (12) is horizontally mounted on the track frame (11) side. When lifted around the fulcrum of the horizontal axis (22), based on the existence of the above-mentioned constant distance (Ll), the third
The transmission belt (41) floats and relaxes as shown in Figure 9.
It has also come to automatically cut off its transmission function. Therefore, it is possible to effectively prevent unexpected personal accidents while not working.

Regarding the above series of working mechanisms (A) to (G), I will first explain the rush pulling mechanism (B), which is biased to the left (uncut side) front position of the working frame (12). At the same time, a pair of inner and outer (right and left) lifting cenocases (51) (52) are arranged side by side in a tilted state at a certain angle.
Endless drawers (53) (54) are housed inside the chamber so that they can be freely circulated in the vertical direction, and each of the drawers (53, 54) is arranged in large numbers at regular intervals and can be raised and lowered freely. Pivotally mounted raising claws (55) (56
), whose raising claws (55) and (56) protrude from the Cheno case (51) and (52) during upward rotation, and act to raise the rushes as if combing them by themselves. Become.

In that case, although details are omitted in the overall views of Figures 1 to 3 and Figure 9, the outside lifting cenocase (52) is supported from behind by the front inclined column (16) of the work frame (12). and the other side is a drawer case (51).
) is fixedly supported by the front end of the inner machine frame (19) in the work frame (12).

(S) is a rush raising passage formed between the opposing left and right sides of the double raising cenocase (51) and (52).
), the inner (right side) cenocase (51) is placed in parallel with its legs spread apart, so that it has a substantially right-angled triangular shape when viewed from the front as shown in FIGS. 3 and 6. However, by opening both chain cases (51) and (52) equally, a lifting passageway (S) opens in a V-shape when viewed from the front.
It may be divided as

In any case, the inner drawer case (
51), Cheno (53) runs around the entire length in the vertical direction! - Contrary to what is built in to get
Inside the outer chino case (52) is stored a hoisting chino (54) that rotates only in its lower half.
The bow raising claws (5) attached to both chains (53) (54)
5) (56) is arranged in a zigzag arrangement, alternating and intertwined, and is arranged in an orderly manner in an upward direction.

A rush raising passageway with a triangular or V-shaped opening when viewed from the front (
S) represents the stock reaping action of the reaping mechanism (D) [where (W) is the bottom so to speak, both raising claws (55) (56
) is the rising action limit (0) of both chain cases (51).
This means that it is positioned at the halfway height of (52).

Moreover, the width of the cutting action (W) at the bottom corresponds to two rows of rushes, one on the inside (already cut side) and one on the outside (on the uncut side). The rush plants in the row can be raised all at once and introduced into the pinching and conveying mechanism (C) on the tip side so that they will eventually merge from the tip side.

In addition, the above-mentioned reaping action width (W) of the rush pulling path (S) corresponds to two rushes, and while simultaneously pulling up the two rushes in one move, the pinching conveyance mechanism (C) of the paddle precedent is used. As far as possible, it is possible to make the double-raised cenocases (51) (52) stand up so that they are parallel to each other when viewed from the front, and to extend the entire length of the double-raised cenocases (51) (52) in the vertical direction. Over and over, each raised Cheno (53)
There is no problem even if (54) is built in so as to have a rotational effect.

(57) is a chenoke case (52) that is pulled up on the outside (uncut side).
) is a secondary power distribution shaft that stands up in an inclined state with a rear end approximately parallel to this, and is supported by the IJ diagonal column (17) on the rear side of the work frame (12). The lower end of this secondary power distribution shaft (57) is connected to the weeding mechanism (A) and the pulling mechanism (B) as shown in FIG.
) and the fourth power transmission shaft (
49) through a second heher gear mechanism (58), and the second heher gear mechanism (58)
By the fifth transmission shaft (59) that extends further downward from the
The clipper blade (60) forming the reaping mechanism (D) is reciprocated linearly in the left and right direction in order to reap the base of the rush.

The clipper blade (60) is mounted and supported on the connecting seat plate (20) of the work frame (12) in a relationship that traverses behind the pulling path (S), and the cutting action width of the stock base is thereby As mentioned above, (W) corresponds to two rushes.

On the other hand, at the upper end of the secondary power distribution shaft (57) there is a third bevel gear mechanism (61) and a fourth bevel gear mechanism located on the inside (right side) of the third bevel gear mechanism (61).
A bevel gear mechanism (62) is installed in parallel via a detour transmission shaft (63), and a fourth bevel gear mechanism (62) is installed in parallel with the detour transmission shaft (63).

It goes without saying that the pair of inner and outer rush raising chenos (53) (54) act synchronously.

(67) is the lifting claw (55) of the lifting mechanism (B).
) (56) This is a blower device for assisting the raising action of rushes and quickly straightening the two rushes up to the tip I11, and the rotational driving force of the blower fan (68) is as described above. It is adapted to be taken out from the outer shaft end of the primary power distribution shaft (40).

That is, in Figure 12, which is extracted and enlarged, (69)
is the hanging pulley (4) of the third power transmission belt (41).
3) is a transmission pawl plate assembled so that it can be freely inserted and removed from the lateral outside and rotated together, and is provided with a support shaft (70) that projects from the center to the lateral outside. . (71) is the blower fan (68) facing this.
The rotation axis of the
A speed increasing gear mechanism (72) for the fan (68) is installed. The speed increasing gear mechanism (72) allows the blower to
The fan (68) itself is designed to be small and lightweight so as not to extend outward from the side of the fuselage (10) as much as possible, yet still be able to generate high-intensity wind power.

The pedestal (75) is for installing the gear case (7
The fan case (76) attached to and fixed to the fan case (76) has a mesh-type air intake port opened in the center thereof, and is further covered from the side with a safety cover (77) from the outside. (7th) is an air discharge pipe connected to the fan case (75), and as is clear from the side view of Fig. 1.9, it is located at the left (uncut side) end of the work frame (12). along the lower front end of the air injection nozzle (79).
) is in an open state pointing toward the rushes to be raised from a position immediately in front of the outer raising chenoke case (52).

In other words, the air injection nozzle (
79) is the outer machine frame (18) of the above work frame (12)
When it is fixedly supported and installed, it is oriented almost directly above in side view, and at the same time when viewed from the front, the inner drawer case (51
) is the fourth one that opens upwards.

Therefore, the rush is a raising mechanism (B) (55).
Immediately before it gets caught in the tip (56), it receives a strong wind force from the blower fan (68) as shown in Figure 13.14, and the air jet quickly rectifies it to a vertical state, and the tip side becomes tangled. Even though the two rushes can be pulled up quickly and without any leakage, there is no risk of damaging the stem culm.

(80) is an air guide plate that receives and stops the air from the air injection nozzle (79) and guides it upward by refraction and reflection.
1) and is attached and fixed to approximately the lower half thereof as a forward-facing projecting member at a constant height. Therefore,
The air jet that hits this is automatically guided upwards and is used to pull up the rushes without any loss.
It has excellent straightening action and detanglement action up to the tip side.

Next, the rush weeding mechanism (A) is used to move the grass from the field to the rushes to be planted prior to the raising action by the raising claws (55) and (56) of the above-mentioned raising mechanism (B). Therefore, it is installed at the frontmost position on the left side (uncut side) of the work frame (12).

That is, (81) and (82) are a pair of parallel inner and outer (right and left) weeding bridge plates that define the stock cutting action width (W) of the cutting mechanism (D), both of which are attached to the work frame (12). It is connected and integrated with the double break frames (18) and (19).

What's more, the double-branched bridge plates (81) and (82) protrude a certain amount further forward than the raised chenokase (51) and (52), as if crawling on the ground, and the outer branched bridge plates (82) ) has a divider at the front end (83)
is fixedly installed, while a rush introduction guide rod (84) is integrally bent upward from the front end of the inner branch bridge plate (81).

(85) is the first section from the front end of the outer branch bridge plate (82).
~As shown in Figure 3, the drawer case (51) (52
) is a vibratory branching rod that is erected with a curved back slope at a gentler angle than that of 1.), and is made of synthetic resin or other flexible material and is curved into an overall circular arc shape when viewed from the side. This curvature gives it a constant amplitude in its orbital motion (the width of the rush is the width of its action).

The front end of the lower part of the vibrating weeding rod (85) is pivotally attached to the rear position of the above-mentioned weeding arrow (83), and similarly the upper part (
& end is fitted into the tip bearing cylinder of the oscillating transmission shaft (86) so as not to rotate, and the oscillating transmission shaft (86)
86) extends rearward and upward while passing through the upper part of the outer drawer case (52).

However, over the entire length in the vertical direction inside the outer lifting ceno case (52), the elongated lifting ceno (54)

A sixth bell gear mechanism is installed between the upper and lower sides of the oscillating grass rod (85) and the secondary power distribution shaft (57) and the oscillating transmission shaft (86) of the vibrating grass rod (85). are transmission-connected. Therefore, the vibrating weeding rod (85) then receives power from the engine (25) introduced from above, and rotates in order to distribute the rushes. Grass also causes this.

At that time, in relation to the two rows of rush, the outside (
The mechanical distribution of the vibration dividing rod (85) directly applies a striking action to the rush plants in the rows located on the uncut side (uncut side). The blower fan (68) is located in front of the chenoke case (52).
The air injection nozzle (79) is facing, and the air jet that will be ejected from now on will also be blown onto the rushes, so the remaining inner rows of rushes will also be affected. Anything that is lying down can be raised without fail, and a synergistic weeding and raising action with the vibrating weeding rod (85) is imparted to the rushes.

In addition, in the illustrated embodiment, the vibration dividing rod (85) that revolves

The rushes that have undergone the weeding action and raising action as described above pass through the raising passageway (S) as the two rushes merge,
As shown in Figure 4, the tip-side clamping conveyor +! (C)
As soon as the tip side is caught, it is immediately cut off by the clipper blade (60) of the stock cutting mechanism (D).

Then, the harvested rush is transported to the rear of the machine (10) in a natural hanging posture with the tip side being pinched by the pinching and conveying mechanism (C). (C) is the rush raising passageway (S

Figures 15 to 23 show the above-mentioned tip side clamping and conveying mechanism (C), and (88) and (89) are a pair of endless double-row type rush clamping belts inside and outside (right and left). The rushes are held elastically by the close contact of the back-to-back surfaces. In that case, the outer clamping belt (89) is connected to a pair of front and rear pulleys (9
0) (91), and by the power introduced from the drive pulley support shaft (92) on the rear side,
It is designed to be run in circulation. As shown in FIG. 10, the drive pulley support shaft (92) of the outer clamping belt (89) connects the reduction gear mechanism (93) to the first transmission shaft (45) standing up from the above-mentioned primary power distribution shaft (40). ).

The remaining front driven pulley support shaft (94) is supported from below by the first hanger frame (95), which is common to the drive pulley support shaft (92).

Reference numeral (100) denotes a first heel tension sojourner that faces the lower surface of the outer clamping belt (89) and is inserted between the front and rear of both the pulley support shafts (92) and (94), and is shown in Fig. 16.21. It has an expandable and combustible double structure consisting of a square bar yoke (101) and its sheath cylinder rail (102), and the clamping belt (89) is It is kept in a constant state of expansion. Needless to say, the sheath tube rail (102) and the reduction gear mechanism (93) are attached to the hanger frame (95).

On the other hand, the inner clamping belt (88), which is parallel to the outer clamping belt (89), also has a pair of front and rear pulleys (104).
(105), but a plurality of intermediate pulleys (106) are also pivotally supported between the front and rear of the pulleys (105).
As a result, the inner clamping belt (88) is subjected to a biasing force that extends from the inside to the outside, and is curved into an overall arcuate shape that comes into close contact with the outer clamping belt (89).

In other words, when the back-to-back surfaces of both clamping belts (88) and (89) are viewed from above as shown in Fig. 21, they form a smooth outwardly convex curved surface as a whole.
Therefore, while the head side of the rush, whose tip side is being pinched and conveyed, is moved sideways inward to the machine body (10) as described later, the overall arcuate shape in front view allows it to be laid down on its side without any difficulty. It can be changed to a different posture.

(107) (10B) is a front side driven pulley support shaft and a rear side driving pulley support shaft of the inner clamping belt (88), and the drive pulley support shaft (108) is connected to the fourth gear mechanism (62). From there, the eighth transmission shaft (11O
) is also transmission-coupled via a reduction gear mechanism (111).

As shown in Fig. 10, the outer clamping belt (89) is rotationally driven by the input from below via the primary power distribution shaft (40) and the first transmission shaft (45), while the inner clamping belt (89) The belt (88) receives input from above via the secondary power distribution shaft (57), the detour transmission shaft (63), and the eighth transmission shaft (IIO), and the belt (88) receives an input from above via the secondary power distribution shaft (57), the detour transmission shaft (63), and the eighth transmission shaft (IIO), and receives input from the upper side via the secondary power distribution shaft (57), the detour transmission shaft (63), and the eighth transmission shaft (IIO). It is designed to be rotated in the direction of transporting the grass (towards the rear of the machine).

(112) is the second belt facing the upper surface of the inner clamping belt (88).
Hanger frame (intermediate play for supporting the intermediate pulley (106) as shown in Figure 15.17) (113)
It is connected and integrated with the reduction gear mechanism (III) via the above-mentioned reduction gear mechanism (III). (114) is the intermediate plate (+13)
A second heel tensioner installed on the top surface of the
As shown in Figure 17.20, the square bar yoke (115)
and its sheath cylinder rail (116), and the driven pulley support shaft (1
07) is attached, and the inner clamping belt (88) is constantly stretched by receiving the pressing force of the compression coil mn enclosed in the sheath tube rail (116).

The hanger frame (11) of the M+ clamping belt (88)
2) is designed to be fixed to the front inclined column (16) of the work frame (12), or its mounting seat (118) also has a slide adjustment elongated hole (119) along the vertical direction. ) are provided in an open row, and the mounting seat (111()) thereof is fixed to the front inclined column (16) by means of the pole (120) passing through this.

Further, (121) connects the seventh beher gear mechanism (109) installed at the upper end of the front inclined column (16) and the reduction gear mechanism (111) of the inner clamping belt (8B) between the upper and lower sides. As is clear from Fig. 15.17, there is also a mounting seat (122) attached to the upper end of the third integrated hanger frame, which also has a slide adjustment elongated hole (123) along the vertical direction. The opening is fixed to the seventh bell gear mechanism (109) by a bolt (124) passing through the opening.

In other words, as mentioned above, the pair of inner and outer (right and left) rush clamping belts (88) (89) attach and detach to the respective hanger frames (95) (112) (121) and the work frame (12). Pol to operate) (99) (12
0) (124) and its receiver can be adjusted and set in advance to the installation height using slot slide adjustment holes (98), (119), and (123). This means that the scooping and sorting action height (b) can be varied in height.

In that case, the mounting seat (118) of the hanger frame (112) on the inner clamping belt (88) and the mounting seat (97) of the hanger frame (95) on the outer clamping belt (89) are orthogonal to each other. Since they are each fixed to the work frame (12) in a plane, the installation state of both the clamping belts (88) and (89) can be enhanced more stably. In addition, both clamping belts (88) and (89) are attached to separate hanger frames (9).
5) Since it is supported by (112) and (121), there is no risk of impeding or restricting the rearward conveyance of the rushes held between the back-to-back surfaces.

However, if the above purpose can be achieved, the specific configuration for adjustment is a slide adjustment slot (9
8) (119) (123) and fixing bolts (99) (120) (124) passing through these, other configurations may be adopted. In addition, the 8th transmission shaft (110
It goes without saying that the length of the inner clamping belt (88) also expands and contracts as the height of the inner clamping belt (88) is adjusted. (125) exemplifies the fixing bolt for its expansion and contraction action.

As shown in Fig. 22, the back-to-back surfaces of both the clamping belts (88) and (89) are provided with a certain interlocking step (1), which prevents rushes from falling off or misaligning. It is possible to reliably and stably hold and convey this without fear of causing damage. Moreover, the back-to-back surfaces are overall non-vertical surfaces, and when viewed from the front and back direction of the aircraft (10) as shown in Figure 15.22, the inner clamping belt (88) is lower than the outer clamping belt (89). They are also installed in parallel, so to speak, in a stacked and tilted alignment state, so that they are slightly taller and shifted upwards.

In other words, the back-to-back surfaces of both clamping belts (88) (89) are the front and rear drive pulley support shafts (92) (1).
08) and the driven boob υ~support shaft (94) (107), its pulley support shaft (92) (
94) (107) The axes (X-X) of (108) are all imaginary vertical lines (H-river (
) and intersect by a certain angle (α), and as a result, the head side of the rush is pinched by these back-to-back surfaces, and the head side of the rush will automatically move forward after reaping. As it is being swung towards the inside of the fuselage (10), it is maintained in a biased state with its legs slightly tilted sideways. However, it is also possible to make the entire back-to-back surface a vertical surface and to arrange both the clamping belts (88) and (89) in parallel in a correctly horizontal installation state.

(126) is a rush bending guide belt with a flexible fulcrum that serves as a movable fulcrum to bend the rush inward while conveying the rush held between the back-to-back surfaces of both clamping belts (88) and (89). As shown in Fig. 20, the inner clamping belt (8B) is wrapped around a pair of front and rear pulleys (127) and (128) in parallel to the lower position of the inner clamping belt (8B). (129) is the inner clamping belt <88) to the drive pulley support shaft (10B),
By being integrally rotatably connected from below, it is assembled into a unit with the inner clamping belt (88).

The rear drive pulley support shaft (
The power is received from the curved guide belt (108) and the curved guide belt (12
6) can circulate in the same direction and at the same speed as the holding belt 111 (88).

In addition, the axis (Y-Y) of the drive pulley support shaft (129) in the rush curve guiding belt (126) is aligned with the drive pulley support shaft (108) that supports the inner clamping belt (88), as shown in FIG. The machine body (10) is bent inward by a certain angle (β) with respect to the axis <X − , the above-mentioned clamping belt (88) (89)
It is arranged almost perpendicularly to the rushes hanging from the back-to-back surfaces of the rushes, and is adapted to properly accompany the conveying action to the rear without giving any resistance to the stem culms of the rushes. (13
0) is the re-drive pulley support shaft (108) (129)
A flexible joint is suggested by its bellows.

Moreover, the bending angle (β
) can be adjusted and set to be large or small in advance, and the degree of curvature of the rush using the curvature guiding belt (126) as a movable fulcrum can be adjusted.
It is also possible to change it.

That is, (131) is a third belt tensioner interposed between the upper and lower sides of the inner clamping belt (88) and the curve guiding bell I- (126), and as shown in FIGS. It consists of cylindrical rails (132) (133) and a square bar yoke (134) that telescopically connects them to each other, and compression coil springs (135) (136) are installed inside the two sheathed rails (132) (133). ) is included. The sheath barrel rail (133) on the rear side is connected to the inner clamping belt (133) by an L-shaped support stay (137).
The front driven pulley support shaft (138) of the bend guiding belt (126) is connected to the intermediate plate (113) of the hanger frame (112) in the third heel tensioner (138).
It is rotatably supported by the square rod yoke (134) of 1). Therefore, the curvature-inducing belt (126) is always kept in a stretched state by the compression coil spring (136).

Also, (139) is a round rod-shaped fulcrum shaft that is integrally extended rearward from the rear sheath barrel rail (133), and is located in the correct position to correspond to the above-mentioned universal joint (+30) as shown in Fig. 18. There is. (140) is a rotary stay that is integrally projected from the bearing tube of the rear drive pulley support shaft (129) in the curve guiding belt (126) in the opposite direction to the front, and has an L-shape when viewed from the side. The sleeve (141), which is integrated with the protruding end of the sleeve, is attached to the fulcrum shaft (139).
It is rotatably fitted onto the sleeve and fixed with an adjustment bolt (142).

(142) is the third heirto ten no yona (
131) from the rear along the longitudinal center line of the fulcrum shaft (131).
9), so that if it is loosened slightly, the rotary stay (140) can rotate freely with respect to the fulcrum shaft (139), and the curved portion that is continuously integrated with the rotary stay (140) can be rotated freely with respect to the fulcrum shaft (139). Drive pulley support shaft (129) of guide belt (126)
) will be refracted. By freely selecting the refraction angle (β) and then tightening the pole (142), the adjustment state of the refraction angle (β) can be fixedly set. In addition, (143) is the fulcrum shaft (139)
) is a through-hole pin for fixing the barrel to the rear sheath barrel rail (133).

In this way, by screwing back the adjustment pole (142), the pulley support shaft (129) of the curve guiding belt (126) is bent. Compared to the fixed clamping guide that changes the degree of curvature of the rush, the adjustment work can be done with a single touch and is highly efficient, and the adjustment state can also be adjusted with stepless precision. There are benefits to be had.

In any case, the front driven pulley support shaft (138) of the curve guiding belt (126) is different from the rear driving pulley support shaft (129) as described above, and is different from the pulley support shaft (107) of the inner clamping belt. (108), so the curved Kll sill (
126), as shown in Figure 20.22.
In a gradually twisted posture, it is wrapped around a pair of pulleys (127) and (128) at the front and rear. The working length (L2) of the curve guiding belt (126) corresponds to approximately the rear half of the inner clamping belt (88).

In this regard, in the illustrated embodiment, the rush gripping belt (88) (
89) drive pulley support shaft (92) (108) and the drive pulley support shaft (129) of the curved guide belt (126)
, each of which is paired with a driven pulley support shaft (94) (
107) Due to the positional relationship with (138), it is arranged on the rear side to introduce power, but the curved guide belt
(126) is gradually twisted as it moves toward the rear of the aircraft (10), and both pulleys (127) and (128)
On the other hand, it is also possible to arrange these drive pulley support shafts (92), (10B), and (129) on the front side and introduce the power from there.

(144) is in contact with the rush of the curved guiding belt (126).

A cushioning membrane attached and fixed by adhesive or other means to the working surface that comes in contact with the belt (126), which is made of sponge or other highly elastic material that is more flexible than the belt (126) itself, during the transport of rushes. Prevents scratches and slipping.

Furthermore, as shown in Fig. 22, the cushion film (144) is fixed and integrated so as to protrude downward by a certain amount (L3) than the band width of the bending guiding belt (126) itself, thereby preventing the bending. No matter what angle of refraction (β) the guide belt (126) is bent at, it will not damage the rushes that curve around this as a fulcrum, and will come into light, elastic contact.

The point of contact (the curved fulcrum of the rush) is indicated by the symbol (P) in the figure.

As long as this purpose can be achieved, it is of course possible to attach and fix the upper end of the cushion membrane (144) so as to protrude from the curve guiding belt (126) by a certain amount (L4) as shown in the figure. Also, the cushion film (144)
It is also possible to make the surface that contacts the rush a convex curved surface to give it a rounded appearance.

Furthermore, (145) is the third belt tensioner (13).
1) and the rush curve guiding belt (126), and are arranged in parallel with each other with an action length L5) corresponding to the front half of the inner clamping belt (88). It is equipped with a plurality of overhanging lugs (146) on which rushes can be caught.

As shown in Fig. 20.21, this retraction belt (145) is wound around a pair of front and rear pulleys (147) and (148), and the rear pulley (148) wraps around the bend guide belt (126). Example: Driven pulley support shaft (1
By assembling and fitting the two integrally rotatable belts 38), they are driven to rotate in the same direction and at the same speed as the curve guiding belt (126).

On the other hand, the front pulley (147) of the retraction belt (145) is connected to the third belt tensioner (131).
Since it is freely rotatably supported by the front sheath tube rail (132), its retraction belt (145) is also kept in a constant tension state by the third belt tensioner (131). .

In other words, the retraction belt (145) is
) to the back-to-back surfaces of both clamping belts (88) and (89), and the curved guide belt (126) serves to reliably draw and introduce the rush tip side from the clamping belts (88) and (89) to the back-to-back surfaces of the clamping belts (88) and (89). 88) During the rearward clamping conveyance by (89), the clamping belts (88) (89) are used to guide the fuselage (10) to curve inward into a smooth arc-shaped sideways state. It is assembled into a unit.

The rush gripping belt that forms the general feeding mechanism (C) for the above-mentioned gripping 1 (
Et8) At the lower position of (89), scrap ejecting and sorting mechanisms (E) are arranged in a horizontally extending state along the front surface of the fuselage (10), and the above-mentioned clamping belt (
88) An example of the base of a rush hanging from (89) is shown on the right (
As shown in Figure 5.6, the rush is swung up to the height W of the bundling bed (32) in a horizontal position, and the whole rush is moved horizontally to the position (already cut side). It is designed so that it can be turned into an arcuate shape when viewed from the front.

That is, the scrap scooping and sorting mechanism (E) for this purpose is as follows:
A pair of upper and lower scoops are fixedly suspended horizontally on the front frame (13) of the work frame (12) so as to intersect with the transport direction of the tip side by the rush gripping belts (88) (89) at almost right angles in plan view. Cheno cases (149) (150), endless scooping chenos (151) (152) stored inside the cheno cases (149) (150) so as to be able to circulate freely in the lateral direction; A large number of scooping claws (153
) (154), and its scooping claw (153)
(154) protrudes from the Cheno case (149) and (150) when turning to the right (inward of the aircraft), and combs the rushes that are caught on them one by one, separating them and removing short and small debris. You will have to scoop it out.

In this sense, the left end (starting point of action) of both straight rechens (151) (152) faces the rear position of the above-mentioned lifting passage (S), and its straight claws (153) (154
) is designed to automatically and reliably catch the base side of the rush hanging from the clamping belts (88) and (89).

In that case, while the lower hollow cenocase (150) is suspended horizontally, the upper hollow cenocase (149) is arranged in a stacked inclined manner.
Therefore, the right end (end point of action) of the hollow cinch (151) faces the height position of the bundling bed (32).

(155) is the above-mentioned Sukurichen case (149) (1
50), an eighth bell gear mechanism is installed between the upper and lower pairs of the upper and lower ones, and this is the 10th bell gear mechanism.
．． As shown in Figure 11, by being transmission-connected to the third transmission shaft (4th), both scooping chenos (151) and (152) can be rotated in the same direction and at the same speed. ing.

(156) is an endless scrap scraping belt that is suspended horizontally in parallel to the lower position of the lower scooping cenocase (150), and is also equipped with a large number of overhanging lugs (157), which are also similar to those mentioned above. Kuricheno (151) (152)
It is designed to be rotated in the same direction and at the same speed.

As is clear from Figure 5.6, the side of the rush that has been subjected to the scooping action of the above-mentioned debris is the scooping hole (151).
(152) uses the pinching position on the tip side as a movable fulcrum, and moves as if it were a fan's contour trajectory (Z-
It is swung around in a pattern Z), and is eventually floated to almost the height of the bundling bed (32), whereupon it is picked up and removed from above the bundling bed (32) by the focusing conveyance mechanism (F). As soon as it is removed, it is sent directly to the rear binding mechanism (G).

The binding mechanism (G) consists of a bill guard (158), a release arm (159), and a needle (
160), backer (161), sensing door (162)
), each of which is equipped with the work frame (12) at the right (already cut side) end of the machine body (10).
The timing gear case (163) is fixedly installed taller than the bundling floor (32) from the supporting stand (21), and is pivoted in such a manner that it faces onto the bundling floor (32) from inside.

A timing gear mechanism (not shown) built into the gear case (163) is transmission connected to the second transmission shaft (46), and the binding mechanism (G) is driven by the power of the engine (25) that will be introduced from now on. This serves to bind the rush roots together.

In that case, backer (161) and needle (160)
The discharge arm (159) and the door (162) are always exposed above the bundling floor (32), and the door (16)
As soon as 2) senses a certain amount of rushes being sent by the focusing conveyance mechanism (F), its needle (16
0), the rushes are bundled into rush bundles (M) and then discharged to the main deck (33) by the discharge arm (159). In this process, one bundle is temporarily moored to the loading TI (39), as described above, and almost at the same time as the bundling action is completed, the clamping and conveying mechanism (C)
The pinching effect on the tip side of the ear is also released.

Further, the converging conveyance mechanism (F) on the stock side extends along a front-rear direction substantially parallel to the pinching conveyance mechanism (C) on the tip side when viewed from above the machine body (lO). And this is the second
As shown in Figures 4 to 26, a pair of front and rear pulleys (164) (
165) and an overhanging rug (16
It consists of an endless converging conveyor belt (167) with
), while orderly conveying it towards the rear binding mechanism (G).

(168) (169) are the front driven pulley support shaft and the rear drive pulley support shaft, and the drive pulley support shaft (
169) is inserted into the upper position of the timing gear case (163) from the inside, and the needle (160) and the discharge arm (1
59), the sensing door (162), etc., it is mounted horizontally and is rotatable about the horizontal axis.

Therefore, the focusing conveyor belt (167) and the bundling floor (32
), a constant raking passage (Q) is opened between the top and bottom of the rush stock, and the grass is swung and floated by the above-mentioned pickle checks 7 (151) (152). The base of the grass plant is automatically pushed into this passageway (Q).

(170), (171), and (172) are a transmission gear and a transmission check 7 that form a timing gear mechanism, and are transmission-coupled with the second transmission mechanism (46) to support the driving pulley of the focusing conveyor belt (167). A shaft (169) is adapted to be rotationally driven. (173) is a fourth belt tensioner interposed between the front and rear of both pulley support shafts (168) and (169), which also has a square bar yoke (
174) and its W! The converging conveyor belt (167) is always kept in an expanded state by a compression coil spring (176) enclosed within the converging coil spring (176).

(177) is the stock alignment cutting mechanism facing the above-mentioned scraping passage (Q), and the above-mentioned timing gear case (16).
3) is attached to the gear case (163) from the inside so that it protrudes forward by a certain amount (L6) from the front surface of the gear case (163) and moves reciprocally along the vertical direction.

In other words, the stock alignment mechanism (177) is in the form of a clipper in which a fixed blade (178) and a movable blade (179) work together as shown in FIG.
8) to the timing gear case (163) Porto (18)
While the movable blade (179) is fixed by the gear case (0), the movable blade (179) is also fixed by the gear case (
163) by a horizontal shaft (181).

(1B2) is a long hole for inserting a pin receiver opened at the end of the movable blade (179), (183) is a crank arm equipped with an engagement pin (184) with the long hole (182),
It is fitted and integrated onto a rotating shaft (185) parallel to the horizontal shaft (181).

The sprocket (18) on the rotating shaft (185)
6) is engaged with the transmission chain 7 (172) which rotates the drive pulley support shaft (169) of the focusing conveyor belt (167). Therefore, the second transmission shaft (4
The movable blade (+79) reciprocates in the vertical direction by the power of the engine (25) introduced from 6), and the fixed blade (17)
Combined with step 8), cut the rush to the base. The stems of the rushes, which are cut evenly without hitting the front side of the timing gear case (163), are regulated and guided along the inner surface rising from the bundling floor (32) of the gear case (+63). The condensing conveyance belt (167) will orderly convey it to the rear.

This cutting action is performed when the harvested rush is bent sideways as shown in Fig. 22, and while the rush is changing direction, as described above, the tip-side clamping and conveying mechanism (
C) By sliding the whole rush in the vertical direction and adjusting and setting its installation height in advance, it is always at the optimal position (scooping and sorting of waste) depending on the height of the rush. (action height) can be clamped.

In addition, the drive pulley support shaft (129) of the rush curve guiding belt (126) attached to the clamping and conveying mechanism (C) is connected to the drive pulley support shaft (108) of the inner clamping belt (88).
By adjusting and setting the refraction angle (β) in advance, the bending guide belt (126)
It is possible to change the degree of curvature of the rush with the movable fulcrum being the movable fulcrum, which will result in the alignment cutting position of the stock head being adjusted accordingly, which means that the clamping position can be set higher or lower. Even if you do, it will always be achieved.

In other words, assuming that the pinching position on the tip side is at a constant height,
When harvesting the rush as a long regular product, the refraction angle (β) is adjusted to a smaller value as shown in FIG. 22. By doing so, the degree of curvature of the rush will increase, and the base of the rush will be aligned with the cutting mechanism (177).
Since the overall length of the rush becomes longer as if the tip side is subtracted by -2 from the head, the cutting length (K) of the base of the rush to be discarded can be shortened.

On the other hand, when harvesting rushes as short, regular products, the refraction angle (β) is adjusted and set to a large value. Then, as shown in Fig. 23, the degree of curvature of the rush will become smaller, and the base of the rush will extend closer to the trimming mechanism (177).
Since the overall length of the rush becomes shorter, the length (K) of cutting the base of the rush to be discarded can be increased, and in this way, the length (K) of discarding the base of the rush can be increased.
can be adjusted freely and steplessly, so to speak.
This waste can be eliminated.

In addition, in the figure, the rush pulling passage (S) is formed with a wide opening as a rush harvester for two-row cutting, but the double-drawing cheno case (51) (52) is used as a rush harvester for mowing two rows. It is also possible to implement the present invention for mowing a single rush by raising the outer part and forming it into a mere guide post without a built-in chino (54).

<Effects of the Invention> As described above, in the present invention, the pulley shafts (92) (94) (107
) to (108), endless rush-clamping belt (88)
(89) is made to be able to circulate freely around its vertical axis, and is placed in a parallel state in the inside and outside positions, so that the tip side of the harvested rush is held between the back-to-back surfaces of both the holding belts (88) and (89). The rushes are lifted and conveyed to the rear of the machine (10), and during the rearward conveyance action, the rushes are transported horizontally so that the stem side of the rushes is swung out inward of the machine body (10). In a rush harvesting machine which is designed to change the overall sideways curved state, the rushes clamped between the back-to-back surfaces of the inner clamping belt (88) should be curved inward at the lower position of the inner clamping belt (88). The rush curve guiding belt (126), which serves as a movable fulcrum, is connected to the above-mentioned clamping belt (88).
A cushion film (144) is provided on the active surface of the curve guiding belt (126) that comes into contact with the rush, either only at its lower end or at both upper and lower ends. Curved guide belt (126)
Since it is attached and fixed as a relational state in which it protrudes from itself by a certain amount (L3) (L4), it has the effect of completely solving the problem of the prior art mentioned at the beginning.

That is, in the case of the present invention, Japanese Patent Application Laid-Open No. 1-25221 mentioned at the beginning
Unlike the fixed clamping guide (19) of invention No. 7, the rush curve guiding belt (1
26) is supported in parallel with the inner clamping belt (88) at the lower position of the tip-side clamping and conveying mechanism (C) so that they can rotate together in the same direction. The aircraft (
10) can be lifted and transported to the rear, and in the process, the direction can be easily changed into an arcuate sideways curved form.

Moreover, on the working surface of the curvature guiding belt (126) that comes into contact with the rushes, the cushion film (144) extends downward or both above and below the belt (126) by a certain amount (
1, 3) Since the belt (14) is attached and fixed in a state where only (14) is overhanging, it is ensured that rushes do not hit the lower end or upper end of the belt (126) and damage it. It is possible to prevent rushes from slipping during transportation, and the cushion ltj (14
4) can be easily attached to the existing belt (126).

In that case, especially if the structure of claim 3 is adopted, the drive pulley spindle (129) of the curve guiding belt (126) is connected to the drive pulley spindle (108) of the inner clamping belt (88) on the fuselage ( By bending the grass inward (10), it is possible to gradually and smoothly bias the rush into a horizontally curved state in the process of transporting it to the rear of the aircraft (10), and the bending angle If (β) is adjusted and set to be large or small, the degree of curvature of the rush will change, so the cutting length (K
) can also be adjusted.

Even if the refraction angle (β) is adjusted in size in this way, the cushion film (+44) attached and fixed to the curvature guiding belt (126)
Since it protrudes downward or both above and below by a certain amount (L3) (L4) than its own band width, the protruding contact point (
Due to the free elastic deformation of the portion P), it comes into light follow-up contact with the rush, and there is no risk of damaging the rush.

Moreover, if the configuration according to claim 4 is adopted, the rush holding belt (8B) (89) or the curved guiding belt (126)
The whole rush-side clamping and conveying mechanism (C) consisting of the above can be slid vertically using its hanger frame (95) (112) (121) to change the height of the clamping position of the rush. The height of the cutting and sorting action for cutting out waste grass is also adjusted according to the height of the rushes, which has the effect of allowing the proper length of rushes to be harvested to be selected.

Furthermore, as claimed in claim 2, an inner clamping belt (88)
