Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a swing sorting device for a combine thresher capable of adjusting the posture of a swing sorting body extending from the lower part of a handling room to the rear. .

[Prior Art] Conventionally, in a threshing machine for combine, which is configured by extending a swinging selection body, which is swingable by suspending front and rear portions by links, from the bottom of the handling chamber to the rear, The sorting body had a structure such that the inclination angle of the chaff sheave could be changed and adjusted.

[Problems to be solved by the invention] However, with such a structure, it is not possible to adjust the amount of leakage but the feed of swing, and in the case where the aircraft tilts back and forth in wetlands, The problem was that the grain feed could not be adjusted and the expected performance could not be achieved.

[Means for Solving the Problems] The present invention solves such a problem and improves swing selection performance. Therefore, one of the front and rear links is a center-folded link. Then, the upper part of the upper link, which is the upper side of the center-folded link, is rotatably pivotally attached to the machine body, and the operating body that can be operated from the outside is interlocked and linked so as to rotate and support the upper link. The posture of the rocking sorting body can be changed by adjusting the lower link following the rotation of the upper link.

[Operation] Therefore, when the threshing machine is tilted in the front-rear direction together with the machine during work in a wetland, the lower link will move when the upper link of the center link is rotated by operating the operating body from the outside. It follows that it is possible to change the posture of the swing sorting body in a horizontal state while changing the supporting position of the swing sorting body by being driven, and when the feed amount of the wet material is to be increased, the same as above. When operated, the attitude of the swing sorting body can be changed to adjust the feed amount.

Example Next, an example shown in the drawings will be described.

1 to 4, FIG. 2 is a side view of the combine, in which a feed chain (8) and a catch rod (9) are laterally provided on the body supported by both crawlers (7). The threshing machine (A) to be equipped is installed, and the cutting section (B) equipped with the cutting blade (10) and each transporting device is arranged in front of the threshing machine (A), and next to the cutting section (B). A driving section (C) equipped with a seat (11) and the like is provided on the side, and is constructed in the same manner as the conventional structure.

As shown in FIG. 1, the thresher (A) has a grain culm supply port (12) and a straw outlet (13) on both ends and a crimping net (14) stretched on the lower side. The handling barrel (1
5) is mounted on the axis, and a dust sorting chamber (17) is formed in the rear of the machine behind the straw mouth (13), which is connected to the side with the suction mouth (16) of the suction dust collector. , The return pan (3a) from the lower part of the handling chamber (4) to the lower part of the dust sorting chamber (17),
Chaff sheave (3b), Glen sieve (3c), sieve line (3d)
The rocking sorting body (3) provided with is extended, and a compressed air fan (18), a first spiral conveyor (19), and a second spiral conveyor (20) are provided below the rocking sorting body (3). Each is deployed and constructed in the same manner as the conventional structure.

The front part of the rocking sorter (3) has a front link (1).
It is hung by (1) and the rear part is hung by rear links (2) and (2), and is swung in the same manner as the conventional type by the rotation of the eccentric wheel (22) fitted to the rotary shaft (21). The swing selecting body (3) is oscillatably installed so that the lower part of the link (2) (2) is connected to the supporting shaft (23) on the swing selecting body (3) side. The upper part is pivotally attached to the support shaft (24) on the side of the aircraft, and the link (1) in front is
(1) is a center-folded link type in which an upper upper link (5a) and a lower lower link (5b) are connected by a connecting pin (25), and is fitted into the eccentric ring (22) to swing. The lower part of the lower link (5b) is connected to the swinging link (26) connected to the front part of the sorting body (3) via a connecting pin (27), and the upper part of the upper link (5a) is a fulcrum on the machine side. An operating body (6) pivotally attached to the shaft (28) and operable by the driving section (C) is connected to an upper portion of the upper link (5a) to rotate the upper link (5a). It is installed and configured so that it can be supported at the same time.

Therefore, when the threshing machine is tilted in the front-rear direction together with the machine during work in wetlands, etc., operate the operation body (6) in the direction of arrow (a) to move the upper link (5a) as shown in FIG. Rotate clockwise to the bottom link (5b)
It follows that while the supporting position of the swing selecting body (4) is changed, the posture of the swing selecting body (4) can be changed to the horizontal state.

Further, when it is desired to increase the feed amount of the moist material, etc., by operating the operating body (6) and rotating the upper link (5a) as described above, as shown in FIG. 1 and FIG. While changing the posture of the swing selecting body (4), it is possible to operate so that the movement trajectory of the swing selecting body (4) changes from the X state to the Y state as shown in FIG. The swing feed amount can be adjusted.

FIG. 5 and FIG. 6 show another embodiment. Contrary to the above embodiment, the rear links (2) and (2) are replaced by the upper links (5).
It is configured as a center-folded link consisting of a) and a lower link (5b), and the operating body (6) is connected to the upper link (5a).
By rotating the, the posture of the swing selecting body (4) can be changed and adjusted as shown in FIGS.

Incidentally, FIG. 7 shows another example, which has substantially the same structure as the above-mentioned embodiment as indicated by the same reference numeral, but the operating body (6) interlockingly linked to the upper link (5a) is provided with a screw rod. Then, the screw body (29) with which the operating body (6) is screwed is provided rotatably by the control motor (30), and as shown in FIG. Is connected so that the control motor (30) can be controlled and operated via a controller (32). When working on wetlands etc., the machine body can be used for forward and reverse operations and traveling on the headland side. When the vehicle tilts in the front-back direction, the sensor (31) detects the tilt and controls the control motor (30) to operate the upper link (5a) to rotate the rocking sorting body (4). The robot can be automatically controlled to be in a horizontal posture It becomes, even under adverse conditions the aircraft is inclined in the longitudinal direction, so that the stable threshing performance can be ensured.

[Effect of the Invention] As described above, according to the present invention, when the upper link (5a) of the center-folding link is rotated by operating the operating body (6) from the outside, the lower link (5b) is driven and swings. It is possible to change the posture of the swinging sorting body (3) while changing the supporting position of the sorting body (3). Dynamic sorter (3)
When the attitude is changed to a horizontal state or when it is desired to increase the feed amount of the wet material or the like, the same operation as described above can be performed to change the posture of the swing selecting body (3) to adjust the feed amount. As a result, it is possible to further improve the rocking / sorting performance while changing the posture of the rocking / sorting body (3) according to the state, and a simple structure that can be surely operated while being easily operated. It has a feature that can be suitably implemented.
