  The present invention includes a combine, in particular, a cutting part connected to the front part of the traveling machine body, and a feeder that conveys the harvested cereals harvested by the cutting part toward the rear side of the traveling machine body. A feeder case, a pivotal support supported by the feeder case so that the position of the feeder case can be changed in the front-rear direction, and a slave located inside the front end of the feeder case in a state of being rotatably supported by the pivotal support. A driving wheel body, a driving wheel body supported so as to be drivable inside a rear end side of the feeder case, an endless rotating conveyance body wound around the driven wheel body and the driving wheel body, An adjustment mechanism provided on the outside of the feeder case, extending over a side plate of the feeder case and the pivotal support, for changing the position of the pivotal support and fixing the pivotal support at the changed position; Prepared, front The adjustment mechanism is connected to the case side member supported by the side plate, the front end side of the front side of the case side member is relatively unmovable to the pivotal support body, and the rear end side can be repositioned to the case side member. And an adjusting rod-like body that is supported so as to be fixable to the change position.

The above combine adjusts the attachment position of the driven wheel body to the feeder case so that the tension of the endless rotating transport body becomes the set tension when the tension of the endless rotating transport body is weaker than the set tension. It is. That is, the position supported by the case side member on the rear end side of the adjusting rod-like body is changed in a state where the fixing of the pivot body to the side plate of the feeder case is released, and is supported by the case side member of the adjusting rod-like body. By changing the length from the part to the part connected to the pivotal support member to an appropriate length, the mounting position of the pivotal support to the side plate can be changed, and the tension of the endless rotating carrier is the appropriate tension The attachment position of the driven wheel body with respect to the feeder case can be changed.

Conventionally, the case side member is constituted by a plate-like spring receiving member and a plate-like reinforcing body, and the case side member supports the adjustment rod-like body in a state of intersecting the adjustment rod-like body. Yes.
In the above-described combine, the support body is supported by the feeder case so as not to be displaced regardless of the driving load by fixing the pivotal support body to the side plate of the feeder case. However, when the tension of the endless rotating transport body is adjusted, if the pivot support is fixed to the side plate, the rearward force is applied to the driven wheel body due to a sudden increase in the transport load. Then, the force of the direction acts on the adjusting rod-like body via the pivot. If the adjusting rod-like body suddenly moves backward, the case side member is bent backward, and the adjusting mechanism may not be used.

  The present invention provides a combine that can easily avoid the above trouble even if the pivotal support is not fixed to the side plate.

The combine according to the present invention is:
A cutting part connected to the front part of the traveling machine body, and a feeder that conveys the harvested cereals harvested by the cutting part toward the rear of the traveling machine body,
The feeder is located inside the front end side of the feeder case in a state in which the feeder case is supported by the feeder case so that the position of the feeder case can be changed in the front-rear direction. A driven wheel body, a drive wheel body supported in a drivable manner inside the rear end side of the feeder case, and an endless rotating transport body wound around the driven wheel body and the drive wheel body. An adjustment mechanism provided on the outside of the feeder case and extending over a side plate of the feeder case and the pivotal support body, for changing the position of the pivotal support body and fixing the pivotal support body at the changed position; With
The adjustment mechanism includes a case side member supported by the side plate, a front end side connected to the pivot support body so as not to move relative to the front side of the case side member, and a rear end side capable of changing a position to the case side member. And an adjusting rod-like body supported so as to be fixable at the change position,
The case side member is
A plate-like member connected and fixed to the side plate in a state intersecting with the adjustment rod-like body;
A support member that is provided across the plate-like member and the side plate in a state of intersecting the plate-like member at the rear of the plate-like member, and supports the plate-like member.

  According to this configuration, when the pivotal support body is not fixed to the side wall and the driving load applied to the driven wheel body is applied to the plate-like member via the pivotal support body and the adjustment rod-like body, the support member causes the side plate to bend. In a state where it is a force member, it supports the rear surface side of the plate-like member, and the plate-like member supports the adjustment rod-like body while being supported by the support member on the side opposite to the side receiving the pressure by the adjustment rod-like body.

  Therefore, even if the pivotal body is left unfixed to the side plate and the backward force applied to the driven wheel is applied to the plate-like member via the pivotal body and the adjustment rod-like body, the plate-like member is independent. Compared to receiving and supporting the adjustment rod-like body, the plate-like member is less likely to be deformed and the adjustment mechanism is less likely to be unusable.

  In the present invention, it is preferable that the support member is connected and fixed to the plate member and is in contact with or close to the side plate.

  According to this configuration, it is possible to equip the support member without causing distortion of the side plate, as compared to connecting and fixing the support member to the side plate.

  In the present invention, the plate-like member is a first member connected and fixed to the side plate, a second member having a through hole that is fastened and fixed to the first member and through which the adjustment rod-like body is inserted, And the support member is configured to contact or approach the side plate via a receiving plate, and the receiving plate is configured to fasten the first member and the second member by a fastener that fastens the first member. It is preferable that the member is fastened together.

  According to this structure, a receiving plate can be mounted | worn with the simple connection structure which combined the fastener which connects a 1st member and a 2nd member with the fastener which connects a receiving plate to a 1st member.
