Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a self-loading riding type harvester for rush, and more particularly to enable the sewed rush bundle to be loaded on the machine body as much as possible. At the same time, the device is devised so that the machine can be safely and stably moved up and down by tilting the machine body forward and upward even when it is loaded.

<Prior art> A riding-type grass harvester operated by an operator riding on a driver's cab is used to load or unload the harvester itself onto or from a transport vehicle such as a light truck on the road. When going in and out, it becomes necessary to climb up and down the harvester itself along the so-called step board that has been set as the inclined state. In addition, when overcoming the headland in the field, the step board may not be used,
There is no change in having to keep the harvester itself in a tilted state.

In view of such a need, as for the riding type grass harvesting machine configured so that the harvesting machine itself can be lifted up in a forwardly inclined state, it has already been disclosed in JP-A-56-21512 and 57-118.
No. 722, No. 58-81709, No. 56-24832, No. 56-286
No. 22, No. 57-127632, and No. 59-95838 are proposed.

<Problems to be Solved by the Invention> However, since the above-described prior art has a common configuration, the Japanese Patent Laid-Open No. 56-21512 is a typical example. The bunch of bundled grass is not only designed to be dropped from the machine to the field, but also the entire machine (frame a) except for the control device (11) and the driver's seat (12). It is kept in a so-called seesaw motion about the support shaft (c) of the shaft cylinder part (b) that crosses the midway position, and is lifted to a forwardly inclined state by the hydraulic cylinder (e). Has become.

Therefore, if the front end of the frame body (a) is lifted, the rear end that descends may inevitably hit the crawler (10) and the field scene. There are design restrictions on the arrangement position of (c).

Moreover, since the grass bundle is not loaded on the machine body, the weight balance as designed can be maintained even if the machine moves the seesaw, and the walking board can be climbed up and down without danger. It may be, but in a self-mounted riding-type harvester that travels by loading the grass bundle after cutting and bundling on the machine body, if the configuration of the above-mentioned known invention is applied as it is, the loaded weight actually changes in size. , The weight balance of the front and rear of the aircraft becomes unbalanced, and with the grass bundle loaded,
It is not possible to safely climb up and down along the walk board.

That being said, if the load capacity is designed to be small in advance, the essential role for improving the work efficiency and light labor will be diminished. In other words, the configuration of the above-described known invention cannot achieve even the purpose of loading a large amount of rush bundles. Furthermore, since the hydraulic cylinder (e) is pivotally attached to the frame body (a) via the open / close connecting links (d) and (d) on the upper surface of the body (1), the meaning of the meaning of the body (1) is also from that point. With the upper surface as a loading platform,
It is difficult to load a large number of grass bundles here.

Moreover, in the case of the above-mentioned known invention, even when the frame body (a) is lifted in a forwardly inclined state, the mowing part (2)
Is still in an operating state, and the power transmission operation from the engine (E) to the mowing section (2) is not automatically released. Therefore, there is a problem that it is very dangerous.

<Means for Solving Problems> The present invention intends to improve such a problem, and therefore, as a self-loading riding harvester of grass, a front part and a rear part of the machine body are pivotally supported laterally. It is connected by a shaft so that the front part of the machine can be moved up and down around the axis of the horizontal axis.In the front part of the machine, weeding mechanism of grass and raising mechanism, nipping on the tip side A transport mechanism, a stock harvesting mechanism, a curb sorting mechanism for scraps a, a focus transport mechanism and a bundling mechanism on the stock base side,
While installing the work power distribution shaft to each of the various work mechanisms, the rear part of the machine body is also shaped as a loading platform for loading the bundle of grasses in the down position, and the rear part of the machine body An engine, which is a drive source of the working mechanism, and an intermediate shaft for transmitting from the engine to the power distribution shaft while being located on the rear side of the output shaft of the engine, are installed, and the intermediate shaft is With the arrangement state in which the fixed axis distance is located at the rear side of the horizontal axis, the horizontal axis and the power distribution axis are placed in parallel with each other, and the intermediate shaft and the output shaft of the engine are endless. With the first transmission belt, the intermediate shaft and the power distribution shaft are also connected to the endless second
It is characterized in that they are connected to each other by a transmission belt.

<Embodiment> Hereinafter, the specific configuration of the present invention will be described in detail based on the illustrated embodiment. In FIGS. 1 to 3 showing the entire harvester, (11) is a general term for the body of the harvester. And
The engine (12) is mounted in a fixed state at a central portion of the front position. Similarly, (13) is a transmission fixedly installed in the central portion of the rear position,
It is connected to the engine (12) via an intermediate shaft (14) and a transmission belt (15).

(16) is a pair of left and right traveling crawlers that are driven to rotate by the engine (12), and (17) is a hydraulic cylinder, by which a grass weeding mechanism (A) and a raising mechanism ( B), a nip transport mechanism (C), a mowing mechanism (D), a currant sorting mechanism (E), a focusing transport mechanism (F) and a bundling mechanism (G).
From the front end side of the machine frame (11) to the work frame (1
It is designed so that it can be moved up and down around the pivot horizontal shaft (19) of 8).

In other words, the work frame (1
8) and the rear position of the fuselage (11) correspond to the horizontal pivot horizontal axis (1
9), the work frame (18) is moved forward and backward around the axis of the pivotal horizontal shaft (19) by the forward and backward movement of the hydraulic cylinder (17) as shown in FIG. That is, they are being lifted. In that case, as is clear from FIGS. 1 and 2, the pivot horizontal shaft (19) and the intermediate shaft (14) are laid in parallel with each other, and more intermediate than the pivot horizontal shaft (19). Assuming that the shaft (14) is located on the rear side, a constant distance (X) is maintained between the front and the rear of the shaft (14).

The upper position of the engine (12) is entirely on the united floor (2
0) and its engine (12)
The upper part of the intermediate shaft (14), the transmission (13), etc. located at the rear part is preferably the first as a loading platform (21) for the continuous grass bundle (M) with the binding floor (20). It is shaped like a groove in side view as suggested by the figure.

In other words, the upper surface of the front part of the airframe (11) is set so as to function as a grass bundling floor (20) of a certain height above the field, and a part of its center is used for shielding the engine (12). While also serving as a cover, the upper surface of the rear portion of the machine body (11) is formed as a grass bundle loading platform (21) lower than the binding floor (20). Incidentally, the binding floor (20) means a binding location of the grass, and is therefore not limited to the uniformly flat surface as a whole but also includes a form of an undulating surface, which means that the loading platform (21). Is also the same.

(22) is a boundary step between the bundling floor (20) and the loading platform (21), and presents an inclined surface that descends to the rear. During work, the bundling floor is passed through this step (22). By forming a continuous surface between the (20) and the loading platform (21), the rush bundle (M) bound on the binding floor (20) is dropped by its own weight to the loading platform (21).
You can kick it up. (23) is a standing side wall surface of the loading platform (21) facing the root side of the bunch of grass (M), which includes, for example, another opening / closing door or extended closing plate as shown by the chain line in FIG. (24) is attached or the standing side wall surface (22) itself is extended to be taller so that the load of the grass bundle (M) can be increased.

On the other hand, the side wall surface of the stack (21), which faces the tip portion side of the grass bundle (M), also stands up and extends slightly taller or becomes a support pillow on the tip side on the opened side wall surface. By installing the bar material, it is preferable to stably support the grass bundle (M) from below and prevent the grass bundle (M) from hanging down from the tip end side. However, one or both of the left and right side wall surfaces may be left open so as to respond to a change in the length of the grass bundle (M). Further, the bottom wall surface (25) of the loading platform (21) is a downward slope which becomes lower on the root side of the grass bundle (M), which facilitates loading and unloading work and loading state. It is advantageous to achieve horizontal stabilization of

(26) is a driver's cab that is integrally dispatched from the fuselage (11) to the rear. Needless to say, it is equipped with a control box (27) and a seat (28), and an awning roof is additionally installed upright. It may be done. In other words, the position just before the driver's cab (26) is arranged as the loading platform (21) for the grass bundle (M), so the operator rides on the driver's cab (26) to operate the harvester. Therefore, it is possible to directly look at the loading amount of the grass bundle (M) and the like, and it is also possible to adjust the loading state.

The work power distribution (29), which is supported on the work frame (18), is located near the front end of the machine body (11) and extends laterally in the left-right direction substantially parallel to the intermediate shaft (14). The shaft is a shaft, and at its end position deviated to either the left or right side, it is transmission-coupled to the engine (12) via the intermediate shaft (14).

That is, as suggested from FIGS. 1 and 2, the power distribution shaft (29), the output shaft (30) of the engine (12), and the intermediate shaft (14) are in a parallel horizontal crossing state, A relatively short endless first transmission belt (31) is wound around the front and rear of the engine output shaft (30) and the intermediate shaft (14) located on the rear side of the engine output shaft (30), and also the intermediate shaft. (1
An endless second transmission belt (32) longer than the first transmission belt (31) is wound between the power transmission shaft (29) and the power transmission shaft (4). (33) is a tension roller of the transmission belt (32).

Therefore, the driving force is distributed from the engine (12) to various working mechanisms (A), (B), (C), (D), (E), (F), and (G) which will be described in detail below. The various mechanisms (A) to (G) that add a series of actions to the grass are driven by the single engine (12) mounted on the machine body (11).

In the case of the present invention, the series of working mechanisms (A) to (G) are arranged in a concentrated manner on the working frame (18) forming the front part of the machine body (11), as is apparent from FIGS. This makes it possible to significantly shorten the series of work steps for rush and process it efficiently, and at the same time, to make the harvester itself small and compact, while maintaining the body (11).
The loading stand (21) disposed at the rear position is secured as wide as possible to significantly increase the loading amount of the grass bundle (M).

That is, when the above-mentioned series of working mechanisms (A) to (G) are described in detail according to the order of the steps, the weeding mechanism (A) that first acts on the grass is the harvesting machine when viewed from above. One of the left and right sides of the binding floor (20) located in the front part of the machine body (11) (in the figure, the left side in the forward direction of the harvester)
It is arranged at the end portion which is biased to. (34) is a fixed weeding rod that forms the weeding mechanism (A), which projects horizontally long in front of the airframe (11), and is eccentric with the front end position of the lower part connected to this as a fulcrum. A flexible vibrating weed rod (36) that performs a rotation (revolutionary motion) action similar to the rope jumping amplitude motion of the center by the shaft (35), as suggested from the side view of FIG. It stands upright at a certain angle after intersecting with.

Therefore, with the advance of the harvester, it is possible to swiftly enter into the stem culm group of the grass that is densely proliferating in the field, and the entanglement of the culm group can be surely unraveled by the above-described motion action. it can. Moreover, since the vibrating rod (36) is supported and connected to the bearing tube (37) of the eccentric shaft (35) so as not to rotate, it is made of a flexible material. Also, there is no concern that the stem culms of the grass will be scratched or entangled with the culms. Similarly, (38) is a transmission shaft for transmitting the power of the engine (12) from above to the eccentric shaft (35), and (39) is a branching arrow.

Immediately after that, the grass that has been weeded is raised to a correct standing posture by the raising mechanism (B). That is, the raising mechanism (B) faces the position immediately after the weeding mechanism (A). Therefore, as is clear from FIGS. 2 and 3, while this is also located in the front part of the airframe (11), It is arranged at the lateral end portion which is offset to one side (also the left side).

(40) is a raising chain case that forms the raising mechanism (B), (41) is a sled, and (42) is a raising guide rod attached to the chain case (40), both of which vibrate. It is erected at a steep angle that is larger than the installation angle of the weeding rod (36) and is inclined upward. (S) is a raising passage formed by an opening between the right and left sides of the chain case (40) and the guide rod (42) that face each other correctly.
The endless inducing chain (43) runs circularly.

A large number of raising claws (44) are pivotally attached to the chain (43) at regular intervals so that the claws (44) can be raised and raised in the passage (S). Only at the time, standing up in a crossing state into the passage (S) and raising it while combing the grass, on the contrary, when returning to descend,
Sit in a buried state inside the chain case (40). (45)
Is a rotary cleaner that cleans the raised claws (44) in the lying state, and is attached to the vicinity of the upper end of the chain case (40). (46) is the same case (40)
Is a gear box installed on the upper end of the.

In that case, as is apparent from the side view of FIG. 1, the vibrating weed rod (36) and the raising passage (S) are in a state of being installed so as to intersect with each other in an X shape at the midway position. Therefore, after the weeding, the grass will be smoothly raised as it is and the required number will be sequentially and correctly raised by the claws (44). Although a pair of upper and lower sprockets on which the raising chain (43) is suspended are not shown, this is also the engine (12).
Needless to say, it is driven to rotate by.

As shown in FIG. 5, the grass that has been raised in the upright posture continues to be lifted and conveyed toward the rear of the machine body (11) with its tip end side being held by the holding and conveying mechanism (C). ing. That is, the holding and conveying mechanism (C) is installed so as to face the position immediately after the raising mechanism (B), and is also at the lateral end position which is biased to one side (left side) of the machine body (11).

(47) is a general term for the nipping and conveying belt that forms the nipping and conveying mechanism (C). As is clear from the plan views of FIGS. 2 and 7, the nipping and conveying mechanism (C) properly faces the raising passage (S) from the rear side. ,
The body (11) extends substantially along the front-back direction. Moreover, as suggested from the side views of FIGS. 1 and 5, at a constant height position corresponding to the tip side of the raised rush, rearwardly inclined installation intersecting with the horizontal plane at a constant angle (α). It is suspended in the state. (L) shows the length of the nipping and conveying action, and (a) and (b) show the respective positions of the action start point and action end point.

More specifically, by extracting the pinching and conveying belt (47) from FIGS. 8 to 12, it is an endless double-row V-belt group (48) on either the left or right side (left side) and the remaining other side. A double row type V pulley (50) (51) which is composed of a pair with an endless double row type V belt group (49) on the side (right side), and both V belt groups (48) (49) are at least one pair in front and rear. ), Each of which is stretched so that it can be circulated. And the other side (right side)
The V-belt set (49) is urged by a required number of double-row type intermediate V-pulleys (52) so as to project from the inside to the outside of the body (11) in a convex curved shape when viewed from above. Since the V-belt group (48) on one side (left side) is elastically adhered to, the tip side of the grass is still sandwiched between them, and it moves rearward under its so-called hanging upright posture. It will be lifted and transported.

In that case, as shown by the reference numeral (H) in FIGS. 9 and 10, preferably, a constant step is provided on the mutual sandwiching surfaces of the two double-row V-belt sets (48) and (49), which results in The stem culms of grass are intentionally bent and transported. When there is a slight change in the amount of rush to be clamped, a large amount of rush-like grass will expand the mutual gap between both V-belt groups (48) and (49), and a small amount of rush will fall off. It is intended to prevent such a situation or a positional shift.

In this respect, in the illustrated embodiment, in order to provide the step (H), the diameter dimension of the double-row intermediate V pulley (52) is changed between adjacent ones of the belt assembly hanging surfaces. However, if the above-mentioned purpose can be achieved, it can be said that, for example, the cross-sectional shape of the belt itself can be set to a bent shape that interlocks with each other.

(53) is an endless retractable belt with a lug (54), which is made of elastic material such as rubber, and as shown in FIGS. 8 and 11, corresponds to almost the first half of the sandwiching conveyor belt (47). Has a working length that extends so as to be parallel to a position directly below the conveyor belt (47) and circulates integrally with the other side (right side) double-row V-belt group (49). They are connected by a common pulley shaft (55) so as to rotate.

In other words, the nipping and conveying belt (47) forms the nipping and conveying mechanism (C) as a so-called unit body with the retractable belt (53), which is also driven by the engine (12). (56) is a pulley drive support shaft of the conveyor belt (47), and (57) is a support frame, and a tension spring (58) built in the support frame supports a pair of left and right V-belt groups (48). The tension action acting along the longitudinal direction of the longitudinal direction is imparted to (49).
(59) is a gear box, and (60) is a transmission shaft.

The pull-in belt (53) of the sandwiching / conveying mechanism (C) moves the grass in the upright posture from the raising passage (S) to the sandwiching / conveying belt (4).
7), and the action start point (d) is slightly forward of the transport action start point (a) of the nip transport zone (47). Then, at the same time as the tip portion side of the rush is pinched by the pinching and transporting zone (47), or immediately after that, by the cutting blade (61) of the cutting mechanism (D), the root side of the rush is stably maintained. The relationship is set to be cut.

Therefore, when the reaping mechanism (D) is also viewed from above,
1) It is located at the end position that is offset to one side (left side). During the above-mentioned lifting and conveying to the rear, short and small scraps of grass are automatically and selectively dropped and discarded. In the illustrated embodiment, as a cutting blade (61) of the cutting mechanism (D), a hair clipper facing the rearward position of the raising passage (S) and reciprocating horizontally and laterally across the passage (S). Although the form is shown, for example, a rotary type or other mechanism may be adopted.

At the lower position of the sandwiching / conveying belt (47) forming the sandwiching / conveying mechanism (C), when viewed from a plane, a left side or a right side (Fig. (In the case of), a currant sorting mechanism (E) extending along the lateral direction is provided, which allows the rush to move from the middle part toward the root part side during nipping and conveying on the side of the tips. A carding action, and the base of the stock is almost united (20)
It is designed to lift and turn to the height of, and in the process of picking up small scraps of grass and picking it up again.

That is, as is clear from FIGS. 1 to 3, the currant sorting mechanism (E) for the grass is located as a whole in the position facing the front part of the binding floor (20) of the airframe (11) (the front of a certain height). In addition, it is installed as a state of extending in the left and right lateral directions intersecting with the sandwiching and conveying direction. To explain this more specifically, the currant sorting mechanism (E) hooks the upper currant transport belt (62) that hooks the middle part of the grass and lifts it diagonally upward, and also hooks the stock section side. It is composed of a pair with the lower curb transportation belt (63) that is brought out substantially horizontally in the horizontal direction, and both of them, as suggested by the side views of FIGS. ) Is located at a position facing the grass in the standing posture that hangs down from the nipping and carrying zone (47), and when the nipping and carrying action toward the rear of the grass is seen, the middle part and the stockholder side will automatically start. It is designed so that it can be hooked on a pair of upper and lower curry transportation belts (62) (63).

The pair of upper and lower currant transport zones (62) (63) are both an assembly of a currant chain case (64) (65) and an endless currant chain (66) (67) that circulates inside the case. In the chain (66) (67), a large number of curling claws (68) (69) are pivotally mounted at regular intervals in the same manner as the raising claws (44). That is, when the currant claws (68) (69) move forward toward the currant transport action end points (g) (h) of the rush as shown by the arrows in FIGS. ) (65) stand up so as to project from each, so that grass can be hooked, and when returning in the opposite direction, the chain case (64) (65)
It is buried and buried inside.

In that case, especially when viewed from the front of the third and sixth illustrations,
The lower currant transport belt (63) extends in a substantially horizontal installation state so that the root side of the grass is brought out in a substantially horizontal direction, while the upper currant transport belt (62) has both sides. As is clear from the figure, the horizontal curving zone (63) in the horizontal state intersects at a certain angle (β) with a so-called side-up inclination installation state, and gradually moves toward the curling conveyance end point (g). Has been extended to be higher. By this, the root side of the grass is finally lifted up to almost the height of the united bed (20) and turned. Therefore, as long as this purpose can be achieved, the lower curb transport belt (63) in the illustrated embodiment may be omitted. The tension chain (66) (67) is also given a tension action, but its mechanism is not shown.

Also, as suggested from FIGS. 1 and 5, when the pair of upper and lower cursed transfer belts (62) (63) is viewed from the side, the curling claws (69) of the lower curb transfer belt (63) are forward. Is in a directing state in which the operator directly looks directly at the other side, while the curling claw (68) of the upper currant transport belt (62) is in a state in which it is directed diagonally forward and upward,
The directivity lines intersect each other at a constant angle (γ), and the action starting point (f) of the lower curl transport zone (63) is the front position, and the action line of the upper curl transport zone (62) is behind it. The relationship is set so that the action starting point (e) is located.

Moreover, as is apparent from the plan views of FIGS. 2 and 7, the upper currant transport zone (62) is in an inclined installation state in which it gradually projects forward as it goes to its action end point (g). The lower curb transfer belt (63) extends in a horizontal line as a whole, so that both transfer belts (62) (63) intersect at a constant angle (θ) and the end point of its action ( Even though g) and (h) maintain the vertical positional relationship, they are in substantially the same position as each other when viewed from a plane.

Since the currant sorting mechanism (E) is configured as described above, during the action of the grass being lifted from the tip side by the sandwiching and carrying zone (47) and sandwiched and carried to the rear, the stock of the grass is obtained. As shown in Figs. 5 to 7, the base side and the intermediate part are sequentially pulled by the curling claw (69) of the lower curry conveying zone (63) and the curling claw (68) of the upper curly conveying zone (62). In the process of hanging up and carrying out in the lateral direction of the relationship intersecting with the sandwiching carrying direction, when it comes to be carded by the curls (68) (69) from the middle part toward the stock base side, Along with the currant transportation, the stock base side is lifted up to almost the level of the binding floor (20) so that it can be transferred in sequence from the lower currant transport belt (63) to the upper currant transport belt (62), and the grass is initially raised. And from the standing posture of pinching and conveying, it is finally changed to the lying posture. And thus.

In other words, the grass is a movable fulcrum at the nipping position on the side of the tip by the nipping and carrying zone (47), and the stock section side is curled up during the delivery to the rear, as if it were the contour of the fan due to the currying belts (62, 63). While drawing a locus, it makes an arc motion, is lifted to almost the height of the binding floor (20), and is transformed into the final prone position by the carding action. As a result, short and small scraps of grass are thrown away even during this action, and entanglement of grass is corrected by the passage of curly nails (68) (69) so that they can be sorted and sorted.

Reference numeral (70) is a cover plate for the currant sorting mechanism (E) which is erected on the front surface of the united floor (20), and prevents accidental intrusion of curly grass to be transported immediately. With the cover of the same meaning, the nipping and transporting mechanism (C), the binding mechanism (G), etc. are also covered and coated, but these are not shown. (71) is a gear box for transmission between the currant sorting mechanism (E) and the intermediate shaft (14), and the currant chain (66)
(67) is also driven to rotate by the engine (12) via a pair of right and left sprockets (not shown).

The root side of the grass that has undergone currant sorting is exposed to the other side (right side) of the binding floor (20) located in the front of the airframe (11), and the end point (g) of the upper currant transport zone (62) ), It will be kicked out, so to speak, on the united floor (20). Since the grass is still being pinched on the side of the tip, the curly claw (68) of the upper currant transport zone (62) runs around, and the force of transporting the stock side causes the stock base to move above. As soon as the end point (g) of the curling action is reached, it moves away from the curling claw (68) and swung backward, so that the binding floor (20)
You will be kicked up.

Then, the kicked grass roots of the grass are inherited by the focusing and transporting mechanism (F) on the binding floor (20) and properly transported to the binding mechanism (G). (72)
Is a converging / conveying belt forming the converging / conveying mechanism (F), and as shown in FIGS. 13 and 14, the lug (73) similar to the retracting belt (53) of the sandwiching and conveying mechanism (C) is fixed. It is composed of a pair of left and right endless elastic belts provided at intervals, and together with the focusing guide (74) and the packer (75), the root part of the grass is conveyed sequentially to the rear.

Therefore, the transport belt (72) of this focusing transport mechanism (F) is the second,
As is clear from the plan view of FIG.
While staying on the other side (right side) opposite to the united floor (2
0) A drive support shaft (76) that rotates about the horizontal axis is provided at the upper end so that the root part of the grass can be smoothly received. The support shaft (76) is driven by the engine (12) via a transmission case (77) with the intermediate shaft (14),
The focused transport zone (72) is circulated and circulated.

In addition, the root portion of the grass that is transported to the rear where the bundling mechanism (G) is present by the focusing transport belt (72) is automatically moved by the cutting blade (78) for aligning the root portion during the transportation process. It is designed to be cut. The stock is sent to the bundling mechanism (G) in a state where the stock parts are neatly arranged.
The aligning cutting blade (78) is the above-mentioned cutting mechanism (D).
Since the cutting blade (61) has a hair clipper shape similar to that of the cutting blade (61), its details are omitted in the drawing, but as suggested by Figs. Needless to say, it is in an upright installation posture that can receive the parts, and is operated around the horizontal axis.

The focused transport zone (72) extends along the front-rear direction of the machine body (11) so as to be substantially parallel to the nipping transport zone (47) on the side of the tip, and during the backward transport by this. However, since the tip of the rush is still subjected to the pinching and conveying action by the pinching and conveying zone (47), when the root part of the plant is finally received by the binding mechanism (G), It will be maintained in a well-ordered, focused and prone posture in a horizontal line, and the irregularity of the weeds will be corrected during the transportation process.

As is apparent from the above description, the binding mechanism (G) faces the position immediately after the focusing transport zone (72) on the binding floor (20), and is located on the left and right sides of the nipping transport mechanism (C) on the tip side. As a pair, it is also mounted at the end position which is offset to the other side (right side) of the machine body (11). (79) is a binding machine that forms the binding mechanism (G), and as soon as a certain amount of the grass is accepted, the binding machine (79) is activated by the action of the sensing door (80), and the lying posture thereof. Immediately after the bundle of grasses (M) is bound by the discharge arm (81), the stack (21) following the binding floor (20) in its lying position is suggested by the discharging arm (81). So to speak, it is kicked off and transferred in a straight line. Incidentally, (82) shows the needle of the binding machine (79), but the binding string is omitted in the drawing.

In that case, since the rush is subjected to the diverting action by the currant sorting mechanism (E) before, it is focused by the focusing transport zone (72) in the prone posture on the binding bed (20),
It will be bound by the binding machine (79), but the lying position of the grass is strictly parallel to the horizontal plane, as suggested by the side view of Fig. 1 and the front view of Fig. 6. It does not mean only the state, the tilted state that the nipping position on the tip side is slightly higher than the root part (the angle that intersects the vertical plane of suspension is
It also includes angle postures that exceed 45 degrees and reach almost 90 degrees).

Furthermore, the completion of the bundling action and the release of the bundling action by the nip transport zone (47) are set so that they are executed almost at the same time, and a certain amount of the rush is completed. Immediately, the grass bundle (M) is immediately and surely kicked out to the loading platform (21).

In other words, in other words, the working speed of the currant carrying belts (62) (63) that diverts the stock portion side is faster than the working speed of the sandwiching carrying belt (47) that nips and carries the tip side. However, it is determined that they are driven to rotate at a considerably high speed, and therefore, the curb transport belts (62) (63) also cause the lateral feed force to cause the scrap grass to move to the other side of the airframe (11) ( It will be discharged and dumped toward the right side), the sorting effect can be stimulated, and the kicking action of the stock root part toward the high-speed bundling floor (20) causes the stock cutting for stock stock alignment. With the blade (78), it is possible to effectively align the stock bases themselves.

<Effects of the Invention> As described above, in the configuration of the self-loading riding type harvester for rush of grass according to the present invention, the front part and the rear part of the machine body (11) are connected by the pivot horizontal shaft (19). The front part of the machine body (11) around the axis of the horizontal axis (19) so that it can be moved up and down. At the front part of the machine body (11), the grass weeding mechanism (A) and the raising mechanism (A) are raised. Shipping mechanism (B), nipping and conveying mechanism on tip side (C), stock harvesting mechanism (D), curb sorting mechanism (E) for scrap a, focusing transport mechanism (F) on stock side and binding mechanism ( G) and the work power distribution shaft (2) for the various work mechanisms (A) to (G)
9) and, while the rear part of the fuselage (11) is also shaped as a loading platform (21) for loading the bundled grass bundles (M) in a prone position, and the fuselage (11) is also formed. The work mechanism (A) to the rear part
To transmit power from the engine (12) to the power distribution shaft (29) while being located rearward of the engine (12) that is the drive source of (G) and the output shaft (30) of the engine (12). The intermediate shaft (14) is installed, and the intermediate shaft (14) is arranged so that the intermediate shaft (14) is located on the rear side by a constant distance (X) from the horizontal shaft (19). The horizontal transmission shaft (19) and the power distribution shaft (29) are slid horizontally in parallel with each other, and the intermediate transmission shaft (14) and the output shaft (30) of the engine (14) have an endless first transmission belt (31). Similarly, since the intermediate shaft (14) and the power distribution shaft (29) are connected to each other by the endless second transmission belt (32), it is possible to surely improve the problems of the prior art mentioned at the beginning. is there.

That is, in the case of the present invention, the work frame (18) forming the front part of the machine body (11) and the rear part of the machine body (11) also have the pivot shaft (1).
9) connected via a hydraulic cylinder (17) around the horizontal axis of the horizontal axis (19) of the fuselage (11).
Only the front part of the vehicle is lifted up as it goes up, and the rear part of the remaining airframe (11) is, so to speak, fixed. The height of cutting the grass can be adjusted by the cutting blade (61) of the cutting mechanism (D).

In addition, the loading and unloading of the rush harvester itself on the bed of the road transport vehicle, the entry and exit of the rush harvester on the field, and overcoming of the headland, etc. are performed smoothly without being restricted by the size of the above-mentioned forward rising inclination angle. It is easy to do, and at that time, it is possible to load and maintain the bundled grass bundle (M) on the loading platform (21) formed at the rear of the aircraft (11) without any trouble.
It is also excellent in the stability of its loading state.

Paradoxically speaking, a loading platform (21) for loading the grass bundle (M) in its prone position is provided at the rear of the fuselage (11) and at the rear of the loading platform. Since (21) is constructed so as not to move up and down, despite the fact that the bundle of grass (M) after binding can be loaded in a stable manner in a large amount as much as possible, it is independent and independent of this. Since the front part of the machine body (11) can be freely moved up and down without any hindrance, therefore, even if the front part of the machine body (11) is lifted up to the forward inclined state, the entire body of the machine body (11) is lifted. There is no fear that the weight balance will be unbalanced, and the walking board can be climbed up and down remarkably safely and stably.

Also, a grass weeding mechanism (A), a raising mechanism (B), a nipping / conveying mechanism (C) on the tip side, a stock harvesting mechanism (D), a currant sorting mechanism (E) for scraps, a stock farming Since the focusing and transporting mechanism (F) and the bundling mechanism (G) on the section side are centrally arranged and installed on the front part of the machine body (11), the front part of the machine body (11) is lifted as described above. Even when the hoisting operation is performed, the series of actions on the grass by the working mechanisms (A) to (G) do not cause any positional deviation and are always maintained in a stable interlocking action state.

Further, the working mechanism (A) to the front part of the machine body (11)
The work power distribution shaft (29) to (G) is also installed, while the work mechanisms (A) to (G) are provided at the rear of the machine body (11).
(12) that is the drive source of the engine and its engine (12)
While located behind the output shaft (30) of the engine (1
The intermediate shaft (14) for transmitting from 2) to the power distribution shaft is installed. Moreover, the intermediate shaft (14) is arranged as a relational array located rearward of the pivot horizontal shaft (19) by a constant distance (X), and the pivot horizontal shaft (19) and the power distribution shaft are arranged. It is laid parallel to (29) in parallel.

The intermediate shaft (14) and the output shaft (30) of the engine (12) are connected to each other through an endless first transmission belt (31), and the intermediate shaft (14) is also operated. Since the power distribution shaft (29) is linked with another endless second transmission belt (32), as described above, the front portion of the machine body (11) with respect to the rear portion thereof has its pivotal horizontal axis ( 19), the endless second transmission belt wound between the front and rear of the power distribution shaft (29) and the intermediate shaft (14), as suggested by FIG. The (32) relaxes, and the transmission of power from the engine (12) to the power distribution shaft (29) is automatically disconnected.

The lid supports the pivotal horizontal axis (1) that connects the front and rear of the airframe (11).
The intermediate shaft (14) has a more constant distance (X) than 9)
This is because they are laid parallel to the rear position. As a result, when operating the front part of the machine body (11) in a forward-inclined state and climbing and descending the step board, a series of working mechanisms (equipped with the front part of the machine body (11) ( A) ~
(G) will be kept in a stopped state of slap operation,
Remarkably safe. Such an effect cannot be expected at all from the configuration of the prior art described at the beginning.
