Description

[Detailed Description of the Invention] The present invention relates to a wrapping prevention device at the inlet of a handling cylinder in a threshing machine.

That is, in a threshing machine configured by fixing an anti-wrapping foil to the inside of the entrance side plate, which fits close to the outer periphery of the foil integrally fixed to the end face of the truncated conical part on the entrance side of the handling barrel, conventionally A scraper was installed, but this scraper had the disadvantage that it could not completely prevent the culm from wrapping.

The present invention is an improvement to solve this drawback, and by rotating the blade from the handling barrel side and devising the shape of the blade, it is possible to reliably prevent wrapping, and it is reliable and simple. The present invention provides a structure that enables suitable implementation.

Next, the embodiment shown in the drawings will be described.

FIG. 1 is a plan view of a part of the threshing machine with a part removed, showing a handling barrel A having a truncated conical part a on one end side and handling teeth 6 implanted on the circumferential surface, and an inlet side plate 5. A handling cylinder shaft 9 is mounted in the handling chamber 8 between the outlet side plates 7, and a supply port 11 is formed above the supply plate 10 in the inlet side plate 5.
A feed chain 12 is installed outside the handling room 8, and the structure is similar to that of the conventional structure.

In addition, a foil 1 whose outer peripheral portion has a U-shaped cross section is fixed to the end face of the truncated conical portion a of the handling barrel A, and a bent edge 13 at the outer end is fixed to the inner surface of the inlet side plate 5. The anti-wrapping foil 2b that fits on the outer periphery of the foil 1 is fixed so as to fit inward, and the anti-wrap foil 2b, which has a semicircular shape on the lower half side, is fixed on the inlet side plate 5, and the anti-wrap foil 2b on the upper half side The semicircular anti-wrapping foil 2a is removably fixed to the inlet side plate 5 via screws 14, and is constructed in the same manner as the conventional structure.

B is a blade plate, which is thin as a whole and has an inclined blade edge 3 on the leading side in the direction of rotation;
The base 4 which does not have the blade edge 3 is slightly bent from the refraction line A to form an inverted shape when viewed from the rotation direction, and the base 4 is provided with holes 15, 15, and the blade body plate B on the side of the blade edge 3.
The part is the foil 1 and the anti-wrapping foils 2a and 2b.
The end portion 4 is joined to the outer peripheral surface of the end side of the truncated conical portion a so as to approach the outer peripheral surface of the anti-wrapping foils 2a, 2b from the outer periphery of the gap C formed between the holes 15, 15. The screws 16, 16 are inserted and fixed, and the double blade body plates B are respectively attached and configured at an interval of 180 degrees.

Therefore, the double-edged body plate B rotates together with the handling cylinder A, cuts the culm that is about to be caught from the gap C to the outer periphery of the anti-wrapping foils 2a and 2b, and refracts the cut culm. This means that it can be guided to the outer circumferential side of the handling cylinder A on the side of the base 4 where it is attached, thereby preventing wrapping.

In this way, the present invention provides a threshing system in which the anti-wrapping foil is fixed to the inside of the entrance side plate and is fitted close to the outer periphery of the foil that is integrally fixed to the end face of the truncated conical part on the entrance side of the handling barrel. In the machine, a thin blade body plate that is formed in an inverted shape when viewed from the rotation direction and has a blade edge on the leading side in the rotation direction is inserted into the gap between the foil and the anti-wrapping foil. from the outer periphery of the anti-wrapping foil to the outer periphery of the anti-wrapping foil.
Since the base side is fixed to the outer peripheral surface of the truncated conical part, the blade plate rotates together with the handling barrel and cuts the culm that tries to wrap around the outside of the anti-wrapping foil with the blade edge. Since the cut culm is guided to the outer periphery of the handling cylinder on the bendable base side, the blade plate can completely fulfill the role of preventing wrapping, and has the advantage that it can be suitably implemented with a simple structure.
