Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is to install a treating tooth base at equal intervals in the circumferential direction over the supporting members at both ends in the direction of the rotation axis, and to treat the treating tooth base. The present invention relates to a threshing device for an all culm throw-in type combine, which is provided with a sham and is provided with a tooth holder below the sash.

[Conventional technology]

In the above-mentioned threshing device in the related art, a gap is provided between the respective treatment tooth bases, and the inner side of the treatment drum is configured to be hollow (for example, see Japanese Utility Model Laid-Open No. 60-153941).

[Problems to be solved by the device]

In the structure as described above, for example, when the threshing processing amount is large, a part of the processed material is aforesaid so as not to be overloaded due to a large amount of the processed material being sandwiched between the treating tooth base and the tooth receiving base. Although there is an advantage that it can be avoided inside the handling cylinder through the gap, and overload operation of the handling cylinder can be prevented,
When the amount of threshing treatment is small or when the culm is wet with rain or morning dew, the treated product may enter into the handling cylinder and carry around, which has the drawback of reducing the threshing treatment capacity.

It is an object of the present invention to provide a threshing device for an all-culm-type combine harvester capable of preventing overload operation and preventing a decrease in threshing treatment capacity.

[Means for solving problems]

The feature of the present invention is that in the threshing device of the all culm throw-in type combine of the above-mentioned configuration, the lid plate that covers the gap between the adjacent tooth bases over the entire length is detachably attached, and the center of the lid plate in the width direction is attached. The part is located on the same rotation locus as the outer peripheral surface of the treatment tooth table, and the connecting portion for the treatment tooth table is recessed inward in the radial direction from the central portion. The effects are as follows.

[Action]

If the amount of threshed material is large, remove the lid plate,
By avoiding a part of the processed material inside the processing cylinder through the gap between the tooth bases, the overload prevention effect is exerted as in the conventional structure, and when the threshed material is small, or when the wet grain culm is used. At the time of threshing, by attaching the lid plate and closing the outer peripheral surface of the handling cylinder in a substantially cylindrical shape, all the threshing material passes between the handling tooth base and the tooth receiving base, which is extremely efficient. It can handle well.

Moreover, the place where the cover plate and the handle plate are detachably connected by, for example, bolts is more radially inward than the outer peripheral surface of the handle plate and the center of the cover plate in the width direction, which are located on substantially the same rotation locus. Since it is recessed to the side, there is little risk that the threshing-processed product will be caught by the connecting bolt or the like and accumulated.

[Effect of device]

As described above, according to the present invention, when the threshing processing amount is large, it is possible to prevent the overload operation state of the handling cylinder from occurring by avoiding the processed material inward of the handling cylinder. Alternatively, during wet threshing, the threshing treatment capacity can be improved, and only a simple part replacement work can be used so that the work state becomes appropriate according to the difference in the amount of treatment.

Moreover, it is possible to suppress the possibility that straw scraps and the like are caught and accumulated on the connecting bolts and the like in the attached state of the lid plate, and the risk of threshing clogging occurring early is reduced.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 3 shows an all-culm input type combine having a pre-mowing treatment section (A), a threshing section (B), and a sorting section (C).

The threshing part (B) is provided with a handling room (1) as shown in FIGS. 1 to 3.
A concave (3) is provided below the handling barrel (2) that is placed inside, and a grain culm supply port (4) is provided at the front of the handling chamber (1), and the handling barrel rotation axis at the rear. A pair of left and right processed material discharge ports (5), (5) are formed so as to be offset to both sides in the direction. And
When the grain culm supplied from the grain culm supply port (4) is subjected to threshing treatment by the handling treatment section on the lower side of the handling barrel (2) and is made to flow along the peripheral wall of the handling chamber by the rotating handling barrel (2). At the same time, one turn is made to guide the flow to the left and right treated material discharge ports (5), (5).

The sorting section (C) is a Glen pan (6) that sorts and transfers the processed material that has leaked through the concave (3) by specific gravity difference, and swings and transfers it backward, and the processed material discharge ports (5) and (5). A straw walker (7) that filters discharged discharged products and swings them backwards.
And a swing sorting device (8) for sorting the processed products sent from the Glen pan (6) and the straw walker (7), and a Karako (9) for sending sorting air to the swing sorting device (8). There is. Then, a collecting unit (D) for collecting the selected grains is provided below the selecting unit (C).

The recovery unit (D) collects the first product and sends it to the side of the fuselage at the feed end of the first product recovery unit (10) and lifts the first product sent to the grain tank (11). A second grain recovery unit (1) that collects the second grain and sends it to the side of the machine (1)
The feeding end of 4) is provided with a returning conveyor (15) for returning the sent second object to the handling room position.

As shown in FIG. 2, the concave part (3) is provided with tooth receiving plates (17) on the left and right arcuate support frames (16), (16) at appropriate intervals in the circumferential direction. A large number of receiving teeth (18) are mounted on the tooth base (17).

Next, the structure of the handling cylinder will be described in detail.

As shown in FIGS. 1 and 2, a substantially disk-shaped support member (around the left and right ends of the rotary drive shaft (19) that is erected and laid over the left and right side walls of the threshing part (B) is provided. 20) and (20) are fixed, and at the outer peripheral portions of these support members (20) and (20), a handle tooth base (21) bent and formed into a substantially U-shaped cross section is attached to both support members (2).
They are erected and fixed at equal intervals in the circumferential direction between 0) and (20). On the outer peripheral surface (22) of the handle tooth base (21), a large number of handle teeth (23) are fixedly extended outward in the radial direction at appropriate intervals along the left-right direction.
