Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a beater for discharging a discharge straw provided in a combine or the like, and more specifically, it is rotatably arranged at a position behind the discharge straw discharge port of a handling room. The present invention relates to a beater for discharging a discharge straw.

[Conventional technology]

As a conventional structure of such beater, for example, the actual Kaisho 61-1 is used.
As disclosed in Japanese Laid-Open Patent Publication No. 04042, the outer peripheral surface of the rotating body is provided with a plurality of plate-shaped blades that are long in the axial direction, and is also disclosed in Japanese Utility Model Laid-Open No. 60-131135. As described above, there has been proposed a structure in which a large number of small-width projections are provided on the outer peripheral surface of the rotating body in the axial direction.

[Problems to be solved by the invention]

However, with the beater in which plate-shaped blades are provided on the outer peripheral surface of the rotating body like the former, the scraping performance of the discharge straw is good, but strong wind is generated by the rotation of the wide blades, and it is arranged below this beater. The wind is blown onto the Glen Pan to form a so-called air curtain, which has a drawback that it has a bad influence on the conveyance of the filtered matter on the Glen Pan.

In particular, when the threshing device is constructed in a small size, the influence of the wind from the beater is great because the distance from the beater to the Glenpan is short.

Also, in the case of the beater in which the outer peripheral surface of the rotating body is provided with a small width projection in the axial direction like the latter, although the wind is rarely generated by the rotational movement of the projection as described above, There is a drawback in that the discharge power is reduced, and in particular, at the end portion on the wall side, the discharge straw is in sliding contact with the wall surface, and the transport force is reduced.

The present invention was made by paying attention to the above situation,
It is an object of the present invention to improve the dischargeability of the discharged straw while preventing the wind from exerting a strong wind due to the rotation of the beater and adversely affecting the conveyance of the litter, as in the conventional case.

[Means for solving problems]

That is, the characteristic configuration of the discharge straw discharging beater according to the present invention is such that a large number of discharge straw scraping projections formed in a small width in the axial direction are arranged at a predetermined interval on the outer peripheral surface of the rotary body, and The blade for scraping out the discharged straw, which is wider than the protrusion in the axial direction, is arranged at the end portion on the side wall side of the blade. The action and effect are as follows.

[Action]

Since a large number of discharge wall scraping protrusions formed in a small width in the axial direction are arranged at a predetermined interval on the outer peripheral surface of the central portion of the rotating body, a large number of discharge straws can be scraped by each projection. Wind is rarely generated by the rotational movement of the protrusions. Then, the wide blades in the axial direction provided at the side wall side end portions of the rotating body assist the lowering of the discharge output of the protrusions, and in particular, can enhance the discharge power of the exhaust wall on the wall side, Is not projected over the entire width of the rotating body as in the prior art, and does not cause strong wind to be blown onto the Glen pan.

[Effect of device]

As a result, it has become possible to improve the dischargeability of the discharged straw while preventing the generation of wind as much as possible and allowing the filtered matter to be conveyed on the Glen pan well. Further, in the side wall, the blades also have an effect of preventing the exhaust straw from being wound around the protrusion.

It is installed in. Further, as shown in FIG. 2, in the upper position of the handling chamber (14), a substantially V-shaped processed material guide (which is formed in a divergent shape from the rear side toward the front of the grain culm input port (8) is formed. 21) is provided.

The sorting unit (22) sorts the processed products that have fallen through the concave (14) and sifts and conveys the processed products rearward while sieving them, and the processed products discharged from the discharge straw discharge port (16). Straw rack (12) that swings backward while filtering
And a swing sorting device (17) for sorting the processed products sent from the Glen pan (7) and the Straw rack (12).

As shown in FIG. 5, the Straw rack (12) is pivotally supported by a crank shaft (34) which is arranged in parallel in the lateral direction with respect to the machine body and is axially mounted in the lateral width direction of the machine body. (34)
Each stroll rack (12) is oscillated while the phase is shifted by 120 degrees by the rotational drive of the. The structure of the respective Straw racks (12) attached to the crankshaft (34) is as follows because it is difficult to obtain the accuracy of each member.

That is, as shown in FIGS. 4 (a) and 4 (b), a pair of front and rear brackets (3
5) and (35), the crankshaft (34) is arranged, a pair of bearings (36), (36) arranged around the crankshaft (34), a pair of curved bearing plates (37 ), (37) and the vibration-proof rubber (38), the Straw rack (12) and the crankshaft (34) are connected.

It is erected, and by operating the rotating shaft, the rear plate (23) is rotated upward to a standing posture to guide the grain culm upward, or the rear plate (23) is turned down to rotate the grain culm. It is configured so that it can be switched to a backward tilting posture that allows backward flow.

As shown in FIG. 1, the beater (18) is formed by bending a steel plate on each outer peripheral surface of a quadrangular cylindrical rotating body (3) in a substantially U-shape to discharge a discharged straw (1). ) Are fixed at equal intervals in the axial direction of the rotating body (3), and at the side wall side end of the rotating body (3) and the rear plate (23) side end, blades for scraping straw ( 2)
It is configured by fixing. The protrusion (1) is formed with a small width in the axial direction of the rotation (3), and the blade (2)
Is formed wider than the protrusion (1) in the axial direction, and is fixed to the front edge of the protrusion (1). Further, on the lower side of the beater (18), a large number of forks (4) for receiving the discharge straw are arranged in a cantilever manner from the rear of the handling room (15) in a cantilever manner in a rearward direction. If processing, this fork as appropriate
(4) Install a shield plate (not shown) between the
It is also possible to prevent the wind from 8) from hitting the Glenpan (7).

Next, in the case where the rear plate (23) is in the standing posture, and the operation in the rearward posture is described, in the state where the rear plate (23) is in the standing posture, the grain cullet insertion port ( The grain culm supplied from 8) into the handling room (15) is scraped and introduced rearward as the handling barrel (13) rotates, and waits upward along the inner surface of the rear plate (23), The guide (21) provided on the upper wall of the handling room (15) diverges left and right to guide the concave again.
It will pass on both sides of (14). Then, when passing through the concave (14), treated substances such as paddy and relatively small straw scraps are filtered through the concave (14) to remove the grain pan.
(7) It is supplied to the upper part, is oscillated to the rear, and is conveyed to the starting end side of the sorting section (22). In addition, the remains such as the exhausted straw left on the concave (14) are sent out to the rear sorting section (22) from the exhausted straw discharge ports (16), (16) through the beater (18). Further, when the rear plate (23) in a tilted posture, the grain culm supplied from the grain culm input port (8) into the handling room (15) is
As the handling cylinder (13) rotates, it is scraped into the rear and introduced, and the paddy and relatively small straw debris are filtered off by the concave (14), and the residue is discharged from the opening at the rear of the handling chamber (15). Is done.
