DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine rocking and sorting apparatus for rocking and sorting grains such as rice, wheat and soybeans that have been threshed in a threshing unit.

[0002]

2. Description of the Related Art In this type of swing sorter, in a horizontal support structure in which a large number of chaff fins are provided between left and right frames, fin receivers attached to the left and right ends of the chaff fins are supported on the left and right frames so as to be tiltable. ing.

[0003]

However, when attaching the chaff fin to such a fin receiver, it is necessary to fix the fin receiver and the chaff fin to each other with a fastener such as Avex to prevent the chaff fin from coming off. When such a fin receiver is supported on the left and right frames of the swinging sorter, the chaff fins are arranged in advance between the left and right frames, and then mounted and supported from outside the left and right frames with fulcrums and movable adjustment pins. There is a hassle such as the necessity. Furthermore, since the fulcrum and the adjustment pin are generally provided substantially in a straight line on the extension of the chaff fin, the fin connecting rod of the adjustment pin interferes with the holding plate supporting the fulcrum pin on the side frame when the chaff sheave is closed. As a result, there is a problem that the adjustment width of the chaff cannot be expanded.

[0004]

Accordingly, the present invention SUMMARY OF] causes the laterally placed a number of Chafufin between the right and left side frames of the swing sorting plate, integrally formed a cylindrical tubular portion to the long hand tabular Chafufin body, the Chafufin the body and the cylindrical portion with removably provided left and right fin receiving the engaged sintering, is inclined adjustably supporting the fins received in the left and right side frames, left and right swing sorting machine

As shown in FIGS. 7 to 10, the first and second chaff sheaves (37) of the front and rear sorting boards (31) and (32).
(39) are left and right swinging side frames (53a) (53b)
A large number of horizontal chaff fins (55) are stretched at substantially equal intervals between (54a) and (54b) so as to be capable of adjusting the inclination angle, and are integrally connected to the left and right ends of each of the chaff fins (55). The upper fulcrum pin (57) and the lower movable adjustment pin (58) on the outer side of the fin receiver (56) are projected outward from the left and right side frames (53a) (53b) and (54a) (54b). (53a) (53b) / (54a)
A holding plate (59) that is bolted and fixed to (54b) holds the protruding ends of the fulcrum pins (57) in a rotatable manner, and also holds the side frames (53a) (53b) and (54a) (54).
The projecting end of each adjusting pin (58) is rotatably held by the fin connecting rod (60) slidably in contact with b), and by the parallel movement of the connecting rod (60) with respect to the holding plate (59). The opening angle of the chaff sheaves (37) and (39) is adjusted by changing the inclination angle of the fin (55).

Further, a mounting hole (61) through which the fin (55) is inserted with the fin receiver (56) integrally connected to the right end of the fin (55) is formed on the left frame (53a) (54).
a) and fulcrum pins (5) provided on the upper and lower sides of the fin receiver (56) at the right end of each fin (55).
7) and an insertion pin hole (62) and an elongated hole (63) for the adjustment pin (58) are opened in the right side frames (53b) and (54b), respectively, and the swing side frames (53a) (53b) and (54a). )
The fins (56) are inserted into and removed from the (54b) from the left side and detached.

The fin (55) is formed in a long flat plate shape with the upper end part being a thick part (55a) that bulges the back side and the middle part having a square cross section bulging the front and back sides. The thick part (55b) and the lower end part are further formed as a cylindrical part (55c) having a rectangular cross section on the front surface side to ensure the strength of the fin (55).

The fin receiver (56) is provided on a thick plate portion (56a) having a fixed length on the inside opposite to the pins (57) and (58), and an inner surface of the thick plate portion (56a). Vertical and horizontal cut grooves (64) and (65), which are recesses of a certain depth, into which the fins (55) are inserted, and are symmetrical about the center line of the vertically long cut groove (64). Each of the grooves (64) and (65) is provided, and a fin (55) is provided between one end of the vertically long cut groove (64) and the middle.

4) On the left and right sides of the other end, an insertion convex portion (66) that fits into the cylindrical portion (55c) defined by the lateral groove (65) is formed, while the fulcrum on the enlarged portion (64a) side is formed. Pin (5
7) is provided on the extension line of the fin (55) substantially the same as the center line of the cut groove (64), and the adjustment pin (58) on the projection (66) side is opposite to the projection (66) from this extension line. It is provided with a fixed offset in the lateral direction.

A semicircular pin guide surface (61a) for guiding and supporting the fulcrum pin (57) is formed at the upper end of the lower side of the mounting hole (61), and at the lower end of the lower side of the hole (61). An adjustment slot (61b) of the offset adjustment pin (58) is formed, and the fulcrum pin (57) is supported on the guide surface (61a) to move the adjustment pin (58) in the slot (61b). Thereby, the inclination angle of the fin (55), that is, the opening degree of the chaff sheaves (37) and (39) is adjusted. When adjusting the rotation of the inclination angle of the fin (55), as shown in FIG. 8, the pin peripheral portion (56b) and the pin having a diameter larger than the diameter of the fulcrum pin (57) in the thick plate portion (56a). The lower side (56c) between (57) and (58) is always attached to the fin inclined portion (67) which is an interference portion between the guide surface (61a) and the slot (61b) in the side frames (53a) and (54a). And make them interfere,
The fin (55) is configured to restrict leftward movement and to ensure smooth rotation of the fin (55).

As shown in FIGS. 11 and 12, two front and rear fixed chaff fins (68a, 68b) are provided between the feed pan (36) and the first chaff sheave (37). Left and right frames (53a) (53

b) a connecting plate (7
2) is detachably fixed via bolts (73) to secure the strength of the fixed chaff fins (68a) (68b).

The present embodiment is constructed as described above, and has a cut groove (64) formed in the fin receiver (56).
In addition, the fin (55) is inserted into the convex portion (66) or the like in a state where it is easily press-fitted, so that these fins (55) are securely assembled. Fins (5) with the receiver (56) attached
5) is inserted to support the fins (55) in a double-supported state with respect to the left and right frames (53a) (53b) and (54a) (54b) of the sorting boards (31) and (32). And the side frame (53a) (53b) of such a fin (55)
(54a) (54b) After assembly, the mounting holes (6
1) The movement of the fin (55) to the outside is prevented by the interference with the fin receiver (56) and the side frames (53a) and (54a), and the fin (55) is securely prevented from coming off. The offset of the adjustment pin (58) prevents the holding plate (59) of the fulcrum pin (57) from interfering with the connecting rod (60) of the adjustment pin (58).
5) The adjustment range of the inclination angle (the range on the closed side is large) can be expanded.
