Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method in which a stem of a harvested grain culm is held in a feed chain and moved in parallel with a handle cylinder axis.
The present invention relates to a combine threshing apparatus that supplies only ears to a handling room for threshing, and receives thresh after threshing from a feed chain to a drainage chain and carries the threshing to a straw processing unit mounted behind the threshing unit. Conventionally, the fourth gutter disposed below a straw transport chain has been formed by joining a plurality of iron plates. [0003] The conventional No. 4 gutter has a problem that it takes time to assemble and attach. According to the present invention, a fourth gutter for guiding grains falling from straw after threshing to a lower swinging sorter is provided at the rear of the handling room in the threshing section. In the combine equipped with the 4th gutter integrally molded with synthetic resin material, the center
On the front guideway that is steeply inclined to the rear of the front,
A gently inclined front guide surface and an approximate
A flat rear guide surface and a right guide connected to the right side of the front and rear guide surfaces
Surface and a steep slope located on the tip side of the straw
Slightly sloping front plan located on the side of the straw stock compared to the front guideway
The upper surface of the inner surface can be formed higher, and the amount of grain falling than the stock side
Smooth flow of grains on the front guide surface on the tip side
By raising the front guideway on the stock company side.

c) and a right guide surface (68d) connected to the right side of the central front and rear guide surfaces (68a) (68c) are resin-integrated, and the fourth gutter (68) has a substantially mountain-shaped cross-sectional shape in side view. ), The falling characteristics of the falling straw from the straw are quickly flown down to the swinging sorter (25) below the front side, and the straw on the fourth gutter (68) is also quickly outboarded. In the back of the handling room (19) in the threshing unit (4), the kernels falling from the thresh after threshing are separated by a rocking sorter (2).
In the combine provided with the 4th gutter (68) for guiding to 5), the fourth gutter (68) formed of a synthetic resin material is compared with the upper surface height of the front-rear width intermediate portion of the synthetic resin right guide surface (68d). The front edge and the rear edge are formed low, and the grains falling from the waste straw are quickly slid down to the rocking sorter (25) side, and the straw is smoothly moved to the straw processing section (9) side. The processing function on the fourth gutter (68) which is easy to assemble and attach is improved. In addition, since the fourth gutter (68) is made of resin and integrated, there is no gap in the production, so that the blowing of the sorting wind from the traditional Karino (32) is eliminated. As shown in FIGS. 9 to 11, the spout (69) at the upper end of the fryer cylinder (31) facing the inside of the grain tank (17) is formed in a substantially F-shaped cross section in side view. Things
Around the semicircle at the upper end of the fryer cylinder (31), it is fixed adjacently so as to surround the inclined bottom plate (69a) of the lower part of the spout (69) to the right (downward toward the center of the tank (17)). The upper end of the fry conveyor shaft (61) is protruded above the upper top plate (69b), and a bolt (7) is attached to the upper surface of the top plate (61b).
The upper end of the conveyor shaft (61) is rotatably supported on a bearing plate (71) fixed via the bearing (72) via a bearing (72). As shown in FIG. 11, a bearing (7) provided between the conveyor shaft (61) and the bearing plate (71) is provided.
2) and a collar (73) between the inner circumference of the top plate (69b) and the bottom plate (69b) and the conveyor shaft (61).
The seal member (74) interposes a circular plate-shaped seal member (74) to prevent dust and the like in the tank (17) from entering the bearing (72) and to reduce the number of parts. are doing. Further, the outlet (69) is provided with a bottom plate (6).
9a) and the vertical side plate (69c) between the top plate (69b)
Are provided at the upper end of the conveyor shaft (66) on the left side of the input blade (75), and the bottom plate (69a) and the top plate (69)
b) before and after (corner portion) the vertical side plate portion (69c),
A guide plate (76) is fixed in a divergent shape in plan view, and the guide plate (76) is used to throw the spout (3)
It is configured to guide the grain in 1a) and to reinforce the outlet body (69). In addition, the outlet body (69) promotes discharge of paddy from the outlet (31a) into the tank (17) by the inclined bottom plate portion (69a), and also connects the bottom plate portion (69a) and the side plate portion (69c). The gap (T) between the corner and the inner wall surface of the tank (17) is made larger than that of the conventional U-shape to enable good discharge without clogging the gap (T) with grains. Things. As shown in FIGS. 12 to 14, the grain tank (17) and the two lower rice discharge cylinders (77) are integrally molded from a synthetic resin material. A block-shaped shutter mounting portion (78) having an outer shape larger than that of the cylinder (77) is integrally formed substantially in the middle, and the shutter mounting portion (78) has a central portion larger than the outer width of the cylinder (77). Open the shutter insertion hole (79)
A shutter (8) having an opening (80) in the insertion hole (79).
1) is slidably provided, and the opening (80) and the shutter (81), which are larger than the inner shape of the cylinder (77), ensure that there is no paddy residue and paddy leakage when the shutter (81) is opened and closed. The shutter (81) is configured to open and close. The shutter (81) is also molded from a synthetic resin material. One end of the shutter (81) is formed into a handle (81a) having a large thickness and a large width, and the handle (8) is formed.
A handle hole (82) is opened in 1a), the opening (80) is opened in the other end of the shutter (81), and the other end of the shutter (81) is bent through a hinge member (83). A regulating member (84) having the same thickness as that of the shutter (81) is freely attached, and the regulating member (84) is bent so as to always overlap with the shutter (81), and a bolt (85) is formed.
To form a stopper when the shutter (81) is pulled out (when opened), and when the shutter (81) is pushed in (when closed), a handle portion (81a) for increasing the thickness and width. Is also used as a stopper to reduce the number of parts. Further, a cover plate (88) is suspended in a free state via a rotation fulcrum member (87) at the rear end of the straw chain cover (86) which covers the feed terminal side of the straw chain (10). Lowered when not working or with a straw cutter (37) (3
In the straw cutting operation according to 8), the straw chain (10) and the like are concealed by the cover plate (88) so as not to be seen from the outside, while the switching plate (8) is placed above the straw chain (10) during bundling.
When the straw is sent out to the rear of the chain (10) after being covered by the chain (9), the straw (8) is transported by the chain (10) to remove the straw.
8) is configured to be pushed open. The present embodiment is constructed as described above, and the fourth gutter (6) conventionally formed by combining a plurality of parts is used.
8) is an integrated molded article made of synthetic resin,
The number of parts can be reduced, processing can be facilitated, and processing cost can be reduced. In addition, due to the good sliding properties of the synthetic resin and the chevron shape when viewed from the side, the grains falling on the fourth gutter (48) can be reduced. It is possible to promptly promote the flow to the swing sorting machine (25) side without stagnation, and also to facilitate the movement of the waste straw in the outer direction of the machine. (32)
It is possible to stably maintain the sorting performance and protect the environment without blowing out the sorting wind from the gap. As is apparent from the above embodiments, the present invention provides a drainage after threshing at the rear of the handling room (19) in the threshing unit (4).
