Further, as shown in FIGS. 1, 7, 8, and 9, the intake blade (62) wound around the outer periphery of the frusto-conical trunk (26) at the front end of the handling cylinder (5), and the handling cylinder (5). 5) The small-width blade (63) wound around the outer periphery of the trunk (26) in the first half and the large blade (64) wound around the outer periphery of the trunk (26) in the rear half of the handling cylinder (5) are connected to the screw. Prepare for the wing (27), 2
A screw blade (27) is formed by the strip intake blades (62) and (62) and the single narrow and large blades (63) and (64), and a plurality of teeth are provided on the small and large blades (63) and (64). (65) are provided at substantially equal intervals. A spiral screw blade (27) is wound around and fixed to the outer periphery of the cylindrical body (26) to form a handling cylinder (5), and a toothing (6) is formed on the screw blade (27).
5) In the combine threshing device for fixing the screw blade (27), the screw blade (27) is formed with a projection (66) at a position where the small-width blade (63) is attached to the outer periphery of the toothing (65), and the screw blade (27). The spiral-shaped reinforcing plate (67) is overlapped and fixed to the small-width blade (63), and the width (L1) of the small-width blade (63) is greatly increased as shown in FIG.
4) is smaller than the width (L2) of the small blade (63) including the protruding portion (66).
3) is formed substantially equal to the width (L2) of the large blade (64), and as shown in FIG. 1, the reinforcing plate (67) or the large blade (64) and the receiving net ( 32) compared with the gap (L4) between the narrow blade (63) and the receiving net (32).
A large gap (L5) is formed between the screw blade (27) in the front half of the handling cylinder (5) and the receiving net (32), and the gap between the screw blade (27) in the rear half of the handling cylinder (5) and the receiving net is formed. It is configured to be larger than the gap of (32). As shown in FIGS. 9 and 10, the holder (68) having a U-shaped end face is attached to the projecting portion (6) of the narrow blade (63).
6) and the large blade (64) is welded and fixed, and the tooth (65) is inserted into the U-shaped part of the holder (68) and fixed with the bolt (69), and is fixed in the rotation direction of the tooth (65). Since the force is received by the holder (68), the force for stopping the teeth (65) by the bolt (69) is small, and the bolt (69) is inserted into the long hole (70) of the reinforcing plate (67). By changing the position of the reinforcing plate (67) by guiding the slot (70) and the bolt (69) in the radial direction about the axis of the handling cylinder (5), the narrow blade (63) and the receiving net are changed. Gap with (32) (L5)
Is changed, and the narrow blade (63) and the receiving net () are provided in a state where the reinforcing plate (67) is overlapped with the protruding portion (66) as shown in FIG. 9 and a state where the reinforcing plate (67) is removed. The gap (L5) with the screw blade (27) formed by the narrow blade (63) in the front half of the handle cylinder (5) is adjusted by adjusting the position of the reinforcing plate (67) or by attaching or detaching the reinforcing plate (67). Receiving network (3
The gap 2) is changed so as to correspond to a change in the threshing amount or the type of crop (rice, wheat, beans) and the like. FIGS. 11 and 12 show a modification in which the toothing (65) is attached. The cross section of the toothing (65) is formed in a wedge shape, and a cylindrical holder (68) having a wedge-shaped opening is provided. ) Is integrally fixed to the screw blade (27), and the rotation of the handle cylinder (5) causes the handle teeth (65) to be caught in the wedge-shaped opening of the holder (68) with a force proportional to the rotation resistance. With the configuration, without using the bolt (69) and the nut as in the above-described embodiment, the toothing (6
5) can be attached to the screw blade (27). As is apparent from the above embodiments, the present invention provides a helical screw blade (2) on the outer periphery of a cylindrical body (26).
7) was wound secured together to form a threshing drum (5), before
Wrapped around the outer periphery of the handling cylinder (5) front frustoconical body (26)
The intake blade (62) to be made and the body of the first half of the handling cylinder (5)
(26) A narrow blade (63) wound around the outer periphery, and a handling cylinder
(5) Large blades to be wrapped around the rear half of the body (26)
(64) in the screw blade (27),
And a large number of teeth (65) on the large blades (63) and (64)
In the combine threshing device, the narrow blade is provided.
Insert the protruding part (66) at the mounting position of the teeth (65) of (63).
And forming, spiral reinforcement plate to said narrow blade (63)
(67) is superposed and fixed, and the width (L) of the narrow blade (63) is
1) is formed significantly smaller than the width (L2) of the blade (64)
And the toothing (6) of the narrow blade (63) including the protrusion (66).
5) Increase the mounting position width (L3) greatly by the width (L) of the blade (64).
It is formed almost the same as 2).
Smaller blade (63) than gap (L4) with net (32)
The gap (L5) between the wire and the receiving net (32) is formed large,
(5) Screw blade (27) and receiving net (32) in the first half
The gap is in contact with the screw blade (27) in the rear half of the cylinder (5).
Be configured to be larger than the gap of the net (32)
To improve grain take-up into the front of the cylinder (5)
The clearance between the screw blade (27) and the receiving net (32) is small.
(5) It is easy to reduce the threshing loss at the rear part.
To increase the threshing amount and improve the threshing function.
This can be easily achieved .
