Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an upper case supporting a handling cylinder, which is supported on a lower case so as to be openable and closable about an axis parallel to an axis of the handling cylinder. Closed posture holding means capable of holding and releasing, and open posture holding means capable of holding and releasing the holding in the open posture are provided, wherein the closed posture holding means includes a first engaged portion in the lower case, and a first engaged portion in the upper case. An engagement fitting is provided, and the first engagement portion of the engagement fitting engages with the first engaged portion in the closed state of the upper case, and engages with the opening of the upper case. The present invention relates to a threshing device configured to cancel the combination.

[0002]

2. Description of the Related Art Conventionally, in the above-described threshing apparatus, the means for holding the open position of the upper case is constituted by a gas cylinder [Japanese Patent Laid-Open No. Hei 9-205858].

[0003]

However, according to the above-mentioned conventional structure, the cost required for the gas cylinder is increased, and there is room for improvement.

Further, when the upper case is opened to perform internal maintenance, the upper case may be closed by an unexpected external force only by the supporting force of the gas cylinder. It is conceivable to provide a piercing rod for supporting the upper case in the open position on the lower case side as the open position holding means, but this increases the number of parts.

An object of the present invention is to make it possible to manufacture a threshing apparatus having an upper case which is difficult to close even when an unexpected external force is applied when it is opened, at a low cost, while suppressing an increase in the number of parts. It is in.

[0006]

[Structure] In the threshing apparatus described at the beginning, the opening posture holding means is configured by providing a second engaging portion on the engaging metal fitting, and the second engaging portion is configured to open the upper case. In this state, it is configured to engage with the first engaged portion and release the engagement when the upper case is closed.

[A] [A] That is, in a state where the upper case is opened, the second engaging portion provided on the engaging metal fitting engages with the first engaged portion on the lower case side to move the upper case. The second engaging portion is disengaged from the first engaged portion as the upper case is closed, while maintaining the open position.

[B] In the configuration of the first aspect, the opening attitude holding means is configured by providing the second engaging portion to the engagement fitting. [C] A conventional opening attitude holding means is constituted by a gas cylinder. Compared with the technology, the cost required for the gas cylinder is not required, and the supporting force for the upper case in the open position is also stronger. The number of parts is reduced as compared to the configured technology.

[0010] Since the second engaging portion is engaged with the existing first engaged portion on the lower case side, another engaged portion dedicated to the second engaging portion is formed in the lower case. It is not necessary, and the manufacturing cost can be reduced as compared with a structure in which, for example, the second engagement portion is engaged with another engaged portion formed on the lower case.

[Effect] Accordingly, a threshing apparatus having an upper case which is difficult to close even when an unexpected external force is applied when it is opened can be manufactured at a low cost while suppressing an increase in the number of parts. .

The construction, operation and effect of the invention according to claim 2 are as follows.

[Structure] In the threshing apparatus described at the beginning, the opening posture holding means is configured by providing a second engaged portion in the lower case, and the first engaging portion is configured to open the upper case. In this state, it is configured to engage with the second engaged portion and release the engagement when the upper case is closed.

[Effect] [E] That is, in a state where the upper case is opened, the first engagement portion of the engagement fitting engages with the second engaged portion on the lower case side to open the upper case. And the first engaging portion is disengaged from the second engaged portion as the upper case is closed.

[F] In the configuration of claim 2, the open attitude holding means is configured by providing the second engagement portion on the engagement fitting.
The same operation as the above [c] can be obtained.

[G] Since the first engaging portion is engaged with the second engaged portion on the lower case side, another engaging portion dedicated to the second engaged portion is engaged with the engaging fitting. No need to form a part,
For example, the manufacturing cost can be reduced as compared with a structure in which the another engaged portion formed on the engagement fitting is engaged with the second engaged portion.

[Effect] Therefore, a threshing apparatus having an upper case that is difficult to close even when an unexpected external force is applied when it is opened can be manufactured at a low cost while suppressing an increase in the number of parts. .

The structure, operation and effect of the invention according to claim 3 are as follows.

[Structure] In the threshing apparatus described at the beginning, the opening posture holding means comprises a second engaging portion provided on the engaging fitting and a second engaged portion provided on the lower case. The second engagement portion is configured to engage with the second engaged portion in an open state of the upper case, and to disengage when the upper case is closed.

[Operation] [H] That is, with the upper case opened, the second engaging portion provided on the engaging fitting engages with the second engaged portion provided on the lower case, and The case is held in the open position, and the second engaging portion is disengaged from the second engaged portion as the upper case is closed.

According to the third aspect of the present invention, the opening attitude holding means is configured by providing the second engagement portion on the engagement metal fitting and the second engaged portion on the lower case. ] Can be obtained.

[Effect] Accordingly, a threshing apparatus having an upper case which is difficult to close even when an unexpected external force is applied when it is opened can be manufactured at a low cost while suppressing an increase in the number of parts. .
