Description

Description: TECHNICAL FIELD The present invention relates to a grain conveying device, and more specifically, a screw for feeding grains in a horizontal direction and a screw for feeding grains from the screw vertically upward. And a transport device provided with.

[Conventional technology]

Conventionally, as a conveying device provided with two screws as described above, there is one disclosed in Japanese Utility Model Laid-Open No. 58-53534, and in this conveying device, a side surface of a lower portion of a screw that feeds grains vertically upward is provided. It is configured to feed the grain from a screw placed horizontally against it.

[Problems to be solved by the invention]

However, in the conveying device configured as in the above-mentioned reference, since the screws arranged vertically are positioned at the ends of the screws arranged horizontally, each screw is connected via gears, etc. Is difficult to unify.

Therefore, it is conceivable to provide a bevel gear at the end of each screw to unify the transmission system, but if the bevel gear is arranged in this way, a space where the screw conveying force does not act at the end of each screw is created. Will be formed. And in this space, since the grain moves only by the pressure from the grain extruded from the horizontally arranged screw, not only the grain is easily damaged, but also the load for transportation is easily increased. There is room for

An object of the present invention is to form a space between the two screws in which a conveying force of the screw does not act, as in the case where a bevel gear is arranged between the horizontally arranged screw and the vertically arranged screw. However, the point is to obtain a transport device that smoothly feeds grains without exerting an unreasonable force on the grains in this space.

[Means for solving problems]

The feature of the present invention is to form a bent flow path in a connecting portion between a first screw that feeds grains in a horizontal direction and a second screw that feeds grains from the first screw in a vertically upward direction. Inside the flow path, the level of the first screw is set higher than the lowest level of the feed path to form a horizontal or substantially horizontal table, and the lowest level of the first screw feed path is the rotation of the first screw. The point is that the inclined surface for guiding the grain starting from the lower level of the distribution channel on the side lifted by is formed in a state of being continuous with the upper surface of the table portion, and the action and effect are as follows. .

[Action]

If the above features are configured as shown in FIGS. 1 to 4, for example, the grain sent from the end of the first screw (2)
(G) is an inclined surface (5) as the first screw (2) rotates.
By reaching the upper surface of the table part (5b) while being guided by c), the level is once maintained and the second screw
It will be sent to the end of (4).

In other words, if the curved flow path (R) is simply formed between the first and second screws (2) and (4), the grain raised by the rotation of the first screw (2) to a high level However, in the distribution channel, after being once lowered to a low level, it is pushed up by the pressure of the grain, whereas in the present invention, the grain that once reached a high level inside the distribution channel (R) (G)
Is supported by the table portion (5b), so that not only a strong force does not act on the grain (G) thus supported, but also the distribution path ( It is possible to reduce the load for pushing up the grain inside R).

〔The invention's effect〕

Therefore, although a screw that feeds the grain in the horizontal direction and a screw that feeds this screw vertically upward are formed, despite a space in which the conveying force of the screw does not act,
In this space, an unreasonable force does not act on the grain, and a transport device that smoothly feeds the grain without increasing the load was obtained.

Particularly, in the present invention, since the two screws can be interlocked and connected by the bevel gears, there is an effect that the drive structure of the transport system can be simplified.

〔Example〕

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

1 to 4 show a first screw horizontally arranged at the bottom of the grain tank (1) of the conveying device for feeding the grains (G) of the grain tank (1) provided in the combine.
(2) and the second screw (4) installed in the lifting tube (3) so as to vertically feed the grain (G) from the first screw (2)
The connecting part with is shown.

That is, the elbow-shaped connecting member (5) is interposed in the connecting portions of the first and second screws (2) and (4), thereby forming the bent flow path (R). , The connecting member (5) has a shaft (2a) for each of the first and second screws (2), (4),
A gear box part (5a) for accommodating the bevel gears (6), (6) for interlocking connection of (4a) is integrally formed, and the feed path of the first screw (2) is provided inside the distribution path (R). Set higher than the lowest level of (S) and the table part (5b) in a substantially horizontal shape,
The lowest level grain (G) of the feed path (S) of the first screw (2) has a starting end at the lower level on the side where it is lifted by the rotation of the first screw (2), and the table part ( Five
An inclined surface (5c) for guiding the grain is formed so as to be continuous with b).

During transportation, the grain (G) sent out from the first screw (2) is lifted by the wing body (7) formed at the end of the first screw (2), After being guided and lifted up the inclined surface (5c), it reaches the table portion (5b), and from this table portion (5b) the second screw
It is designed to be delivered to the end of (4).

[Another embodiment]

The present invention is applied to various parts other than the above-mentioned examples, for example, it is arranged between a screw for collecting No. 1 obtained by a combine threshing device and a screw for feeding grains from this screw, etc. It is also possible to form the inclined surface into a linear slope.

It should be noted that reference numerals are added to the claims for convenience of comparison with the drawings, but the present invention is not limited to the structures of the accompanying drawings by the entry.
