In the combine described in Patent Document 1, when the rake frame is raised, the hunger frame also rises. In this way, even when the maintenance is performed only for the tilting operation, the hungry conveying device rises with the tilting. Therefore, the operation of the hungry conveying device due to the opening of the perimeter of the hungry conveying device Removal, etc.) is likely to occur.

In view of the above situation, there is a demand for a combine which is convenient for carrying out maintenance work for a class.

Further, in the combine described in Patent Document 1, since the lock mechanism is provided at a position close to the swing axis, the free end side portion of the hunger frame easily rattles in a state in which the hunger frame is held at the lowered position.

In view of the above situation, there is a demand for a combine capable of stably maintaining the position of the hungry frame in a lowered position.

Further, in the combine disclosed in Patent Document 1, only one tension pulley is provided, and a support shaft dedicated for the tension arm must be provided. Therefore, there is room for improvement in that tension is effectively applied to the power transmission belt and that the supporting structure of the tension pulley is rationally constructed.

In view of the above situation, there is a demand for a combine capable of efficiently imparting tension to the transmission belt and structurally supporting the tension pulley.

A feature of the present invention is that,

A feed chain for supporting and conveying the cut-

A threshing device for performing a threshing process on a part of the cut-away grain conveyed by the feed chain by a tilt;

And a hatching and conveying device that is continuously provided on the rear side of the threshing device and receives the hatching after the threshing process from the feed chain,

A racing frame capable of swinging up and down about a pivot axis extending in a gas front and rear direction while supporting the swing,

A hungry frame capable of swinging up and down around a pivotal axis extending in the gas front and rear direction and supporting the hatching and conveying device,

The raising frame can be elevated in a state where the hunger frame is positioned at the lowered position.

Normally, in the case of removing the interstices caught by the tilting, it is necessary to raise the tilting to a somewhat high position. On the other hand, when the tilting of the hungry conveying device is removed, the necessity of raising the tilting position to a position as high as the tilting is low. According to this characteristic configuration, the rising angle of the hunger frame can be appropriately set based on the characteristics of the hungry conveying device.

Further, in the present invention,

It is preferable that, in a state where the rake frame and the hunger frame are raised, the hunger frame may be lowered integrally with the rake frame, or the hunger frame may be lowered independently of the rake frame.

Further, in the present invention,

It is preferable that the lock mechanism has a lever for switching to a hook engagement position for engaging the hook with the shaft member by an artificial operation and a non-engagement position where the hook is not engaged with the shaft member.

According to this characteristic configuration, the operator can easily switch the locking mechanism from the engaged state to the engaged state by merely manipulating the lever.

Further, in the present invention,

It is preferable that the lock mechanism does not protrude downward beyond the lower end of the side frame.

According to this characteristic configuration, the lock mechanism does not protrude downward from the side frame and is not disturbed.

According to this feature, the tension can be effectively applied to the transmission belt by the swing side tension pulley and the fixed side tension pulley. Further, the supporting structure of the swing side tension pulley or the fixed side tension pulley can be rationally constructed by using the electric shafts as support shafts for tension arms and using the hunger frames as support members for the fixed side tension pulleys. Further, for example, a mechanism (for example, a tension spring or the like) for imparting a rocking pressing force can be simplified as compared with the case where both of the two tension pulleys are made of a swinging type tension pulley.

Further, in the present invention,

Wherein the fixed side tension pulley contacts the upper path portion of the transmission belt from below,

It is preferable that the swing-side tension pulley be in contact with the upper path portion of the transmission belt from above.

In this case, for example, when the fixed-side tension pulley is in contact with the upper path portion of the transmission belt from above and the swing-side tension pulley is in contact with the upper path portion of the transmission belt from below, The tension pulley may be spaced apart from the tension pulley, or the swing side tension pulley may be separated from the transmission belt by its own weight. According to this feature, the transmission belt is wound on the fixed side tension pulley by its own weight, and the swing side tension pulley contacts the power transmission belt by its own weight. By this. It is possible to more effectively apply the tension to the power transmission belt.

Further, in the present invention,

It is preferable that the fixed side tension pulley acts on a portion of the transmission belt near the drive pulley side between the drive pulley and the driven pulley.

According to this feature, since the length of the portion of the transmission belt extending between the fixed side tension pulley and the drive pulley is shortened, tension can be effectively applied to the power transmission belt by the swing side tension pulley.

Further, in the present invention,

A support shaft for swingably supporting the hung-

An arm which is pivotably supported by the support shaft and is provided over the support frame and the support frame,

And a gas damper for swinging the hung-over frame upward,

It is preferable that the end of the gas damper on the side of the hull frame is connected to the end of the arm on the side of the hull frame.

According to this feature, since the hunger frame is supported by the arm and the gas damper, the hunger frame can be supported more reliably than when the hunger frame is supported only by the gas damper.

Further, in the present invention,

It is preferable that the gas damper and the arm are disposed above the lower end of the moving body portion.

According to this characteristic configuration, it is possible to prevent the gap between the lower portion of the body portion from being transported from being hindered by the gas damper and the arm.

Further, in the present invention,
