DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described below based on examples shown in the drawings. First, the axial flow type general-purpose combine (A) shown in FIG. 10 will be briefly described. The cereal stem is caused by the raising tine (2) of the raking reel (1), and is also raked and cut by the cutting blade (3). The cut culm is a platform auger (4)
To feeder house (5) chain conveyor (6)
To the threshing unit (7) and screw-type rotor (8)
Threshed. The threshed by the rotor (8) falls from the receiving net (9) to the rocking sorter (10), and is sorted by the blower fan (11) such as Karino and the rocking sorter (10). (12) is a traveling crawler, (13) is a control unit, and (14) is a second mower.

In the above combine (A),
In the present invention, as shown in FIGS. 1 and 2, in front of the raking reel (1), the direction of the grain stalk that has fallen down mainly in parallel with the machine body traveling direction is forcibly changed, and the raising tine (2) ) Is provided with a lodging cereal culm alignment device (20) that can work well. The lodging grain stalk alignment device (20) includes a support member (22) in which a number of rod-shaped setting claws (21) are planted, and a disk-shaped support member that pivotally supports both ends of the support member (22) to a peripheral portion. The rotating member (23) is constituted by a rotating member (23) and a rotation driving means for rotationally driving the rotating member (23).
The support member (22) provided laterally in front of the raking reel (1) swings in the machine body width direction by rotating.

The rotary drive means for rotating the rotary member (23) includes a drive shaft (24) pivotally mounted at the center of the rotary member (23), which is operatively connected to one bevel gear in a bevel case (25). A chain (28) is wound around a small sprocket (26) supported by the other bevel gear meshing with the bevel gear and a large sprocket (27) supported by the rotating shaft (15) of the raking reel (1). The rotating member (23) is rotated by the rotational power of the scraping reel (1), and the supporting member (22) is swung. Therefore, there is no need to separately provide a rotation drive device or the like, and the configuration can be simplified.

[0008] The lodging grain culling device (2)
According to (0), the tip of the setting claw (21) is supported by the support member (2).
Because it swings so as to draw an arc according to 2), it works favorably on grain culms that lie down in parallel to the machine's direction of travel, and it is possible to reliably change the direction of grain culms during head-cutting or after-cutting. it can. Therefore, regardless of the lodging direction of the grain culm, the raising tine (2) of the raking reel (1) can be made to act favorably, and the lodging grain culm can be reliably caused to be scraped. Become. The bevel case (25) is supported by a connecting member (29) connected to the rotating shaft (15) of the raking reel (1), and the sprockets (26) and (27) and the chain (28) are formed by a casing (30). It is arranged in. Also, a rotating member (23)
Is mounted with a weight (31) as a balancer. In addition, it is sufficient that the rotation drive means is provided on only one of the left and right sides and the other can be driven independently.

Further, as shown in FIG. 3, when a plurality of (two shown in the figure) support members (22) on which a large number of setting claws (21) are implanted are arranged in a row in the longitudinal direction of the fuselage, the falling grain is further reduced. The effect of aligning the culms increases. That is, the support member (2)
A pivot (3) on a rotating member (23) on which 2) is pivoted.
2), another rotating member (23 ') is further attached, and, similarly to the above, another supporting member (22') on which a large number of setting claws (21 ') are implanted is attached to the rotating member (23'). ), And the rowing device of the lodging culm is arranged in two rows. When the setting claws are rocked in two rows in the longitudinal direction of the machine in this manner, the action of alignment with the lodging grain is improved, and the weight is not required for the second and subsequent rows, so that the balance is improved.
At this time, it is necessary to set the phases of the respective setting claws (21) (21 ′) so as to be alternately shifted. In addition, since the connecting member (29) is rotatably connected to the rotating shaft (15) of the scraping reel (1), the lodging grain culm aligning device (20) is not used when the culm is not used, such as in the case of a napped culm. 2 and 3, it can be moved to an upper position out of the way.

Further, when the raising tine (2) of the scraping reel (1) is configured to be rotatable around the vertical direction, the raising tine (2) works well not only on the grain stem but also on straw and the like. Will be able to do that. That is, as shown in FIGS. 4 to 7, a tine connecting rod (33) is juxtaposed in parallel with a pivot shaft (tine bar) (16) to which the raising tine (2) is attached, and the tine connecting rod (33) is provided. )
And fixed by penetrating the upper part of the raising tine (2). A spring (36) is fitted between stoppers (34) and (35) provided at one end of the tine connecting rod (33), and the tine connecting rod (33) on the side on which the spring (36) is fitted. ) Is configured so that the end (33a) of the shaft support member (17) can protrude outward, and the end (33a) of the tine connecting rod (33) abuts on the inner surface of the shaft support member (17). The cam (3) as shown in FIGS.
7) is fixedly formed or formed.

As shown in the drawing, a stepped portion (37a) is formed on the surface of the cam (37), and a stepped portion (37a) is formed. Since it is fixed or formed on the inner surface of the shaft support member (17),
As the scraping reel (1) rotates, it rotates about the pivot (16). Therefore, the end (33) of the tine connecting rod (33) juxtaposed to the pivot shaft (16).
a) moves in a circular manner while abutting against the surface of the cam (37), and when falling into the step (37a), the elastic force of the spring (36) causes the tine connecting rod (33) to move. 3) The entire body slides in the machine width direction, and the directions of the raising tines (2) connected to the tine connecting rod (33) change simultaneously.

At this time, the range θ in which the raising tine (2) changes, that is, the range θ which can be rotated around the vertical direction is about 9
0 degrees, and the cam (3) changes its direction at an angle in this range only when the raising tine (2) is located at a lower position.
7) etc. are set. That is, as shown in FIG. 5, when the pivot shaft (16) is within the range of α, the end (33a) of the tine connecting rod (33) is set to be located at the step (37a). . Thus, when the raising tine (2) rotates and approaches the ground, the raising tine (2)
If the bent portion (2a) is oriented so as to be perpendicular to the advancing direction of the body, not only the cereal stem but also straw and the like can be scraped well.

Further, the ranges of β and γ before and after indicate when the cam (37) is located on the inclined surfaces (37b) and (37c), respectively. The direction of the bent portion (2a) of the raising tine (2) gradually changes with the rotation of the scraping reel (1). Therefore, the bent portion (2a) of the raising tine (2) after the straw or the like is raked in gradually becomes the original direction parallel to the body traveling direction by the inclined surface (37c) of the cam (37). The transfer to the platform auger (4) can be performed smoothly. In addition, (18) shown in FIG. 2 shows another second mower, and (19) is a cover body when the second mower (18) is stored.

Further, when the raising tine (2) of the squeeze reel (1) is configured to be swingable in the advancing direction of the machine simultaneously with the rotation of the squeeze reel (1), furthermore, the tine (2) is further improved. The raising tine (2) can be made to act satisfactorily on the grain stem that is lying down in parallel.
That is, a plurality of pivots (16) to which the pulling tine (2) of the scraping reel (1) is attached are supported by a plurality of shaft support members (17). As shown in FIG. 8, a reel disc (38) whose other end is connected to the periphery is loosely fitted to the rotation shaft (15) of the scraping reel (1), and the rotation of the rotation shaft (15) is stopped. A pin (39) inserted in a direction perpendicular to the axial direction axially attaches to the shaft so as to transmit and couple torque so that the reel disc (38) can swing around the pin (39) in the machine width direction. It is configured so that Then, one connecting portion (40) of the pivot shaft (16) to which the raising tine (2) is attached and the shaft supporting member (17) is connected by a link ball (41) to have a degree of freedom. Configured as
The other connecting part (42) is connected by a centering bearing (43) having the same effect as the link ball, and a connecting member provided at the end of the pivot shaft (16) in the connecting part (42). (44) and a shaft connecting member (4
5) is connected by a link ball (46) so as to have a degree of freedom.

The shaft connecting member (45) is connected to a rotating member (47) supported on a rotating shaft (15) between the reel disk (38) and the connecting member (29). The member (47) is connected to the rotating shaft (1) near the connecting member (29).
A pivot (49) is attached to a pivot member (48) fitted to 5).
Have been. The pivot member (47) has a pivot (4).
A lever (50) capable of rotating the rotating member (47) about 9) is fixed. Therefore, when the lever (50) is vertically rotated about the pivot (49), the rotating member (47) swings in the machine width direction as shown in FIG. ) Through the pivot shaft (1
6) swings in the machine width direction, and simultaneously swings in the machine width direction while the raising tine (2) is suspended in parallel. For this reason, with the rotation of the scraping reel (1), the lever (50)
When the pivot shaft (16) is swung in the body width direction by controlling the vertical rotation of the arm, the raising tine (2) swings in the body width direction while rotating, and the raising tine (2) is rotated. The trajectory draws a trajectory having an oblique angle with respect to the aircraft traveling direction. Therefore, the raising tine (2) can be made to act on the grain stalk from an oblique direction, and it can be made to reliably act on the grain stalk that is lying down parallel to the machine body traveling direction. Become.

In any case, according to the apparatus for arranging lodging grain of the present invention, the direction of the falling grain stem can be forcibly changed in parallel to the direction of the machine body. Even when the grain culm is laid down, the raising tine of the raking reel can be made to act reliably, and the grain culm can be scraped satisfactorily. Needless to say, the present invention is not limited to those shown in the drawings, and can be appropriately changed in design within the spirit of the present invention.

Along with horizontally laying a support member in which a large number of setting claws for aligning the lodging grain stems in a certain direction are planted, both ends of the support member are pivotally supported by rotating members, and the rotating member is driven to rotate, Since the support member is configured to swing in the machine width direction, it is possible to forcibly change the direction of the grain stalk that is falling down in parallel with the machine body traveling direction, and the raising tine of the raking reel reliably acts. Will be able to do that. In addition, a plurality of support members in which a large number of setting claws are implanted are arranged in a plurality of rows in the longitudinal direction of the fuselage, and each of the setting claws is configured to be displaced differently from each other and swing, so that the direction of the lodging grain culm can be more reliably determined. It can be changed, and the raising tine can work more reliably.

A connecting member for supporting the rotating member is connected to the rotating shaft of the scraping reel, and the connecting member is configured to be rotatable about the rotating shaft. The support member and the like can be moved out of the way. Further, since the rotating member is configured to be rotated by the rotating power of the scraping reel, it is not necessary to provide a separate rotation driving device or the like, and the configuration can be simplified. If the direction of the raising tine of the raking reel is configured to be changeable, it can be made to work well on straw or the like, and the raising tine of the raking reel can swing freely in the machine width direction. With this configuration, the raising tine can be more reliably applied to the grain stem that is lying down in parallel with the body traveling direction.
