Description

  According to the present invention, a harvesting and transporting device is connected to a front portion of a combine main body by a hydraulic cylinder so as to be driven up and down. The front part of the combine main body is configured to include a cutting processing unit that feeds and joins, and a rectangular tube-shaped feeder that conveys the crops merged in the cutting processing unit toward the threshing device provided in the combine main body. A boarding operation part is provided in a state of being positioned at one end side in the body width direction, the cutting processing part is located in front of the boarding operation part, and the feeder is the other side in the body width direction of the boarding operation part. It is related with the usual combine combine deployed in the state.

  In this type of ordinary combine, conventionally, the hydraulic cylinder for driving and raising and lowering the cutting and conveying apparatus has been configured to be pivotally connected to a connecting portion formed on the lower surface side of the bottom surface portion of the feeder (for example, (See Patent Document 1).

JP-A-11-266656

  In the above conventional configuration, the hydraulic cylinder is pivotally connected to the connecting portion formed on the lower surface side of the bottom surface portion of the feeder, so that the bottom surface portion may be bent and deformed. That is, since the load of the cutting and conveying apparatus is received by the hydraulic cylinder via the bottom surface portion of the feeder, the load is applied in a direction substantially orthogonal to the bottom surface of the bottom surface portion. As a result, stress concentrates on the bottom surface of the feeder, and there is a risk that the periphery of the feeder will bend downward and deform around the connection point with the hydraulic cylinder.

  Therefore, in order to prevent such deformation at the bottom of the feeder, the cutting and conveying device is supported by a hydraulic cylinder so that it can be raised and lowered, such as a large reinforcing member having a large strength at the location where the connecting portion of the feeder is provided. There was a disadvantage that the support structure to do so became complicated.

  An object of the present invention is to provide an ordinary combine that can simplify a support structure for supporting a cutting and conveying apparatus in a vertically movable manner by a hydraulic cylinder.

In the ordinary combine according to the present invention, a harvesting and conveying device is connected to a front portion of a combine main body by a hydraulic cylinder so as to be driven up and down freely, and the harvesting and conveying device harvests a crop with a predetermined cutting width and removes the crop that has been harvested.

In addition, since the vertical wall portion receives a load in the direction along the plate surface, even if the vertical wall portion is not thickened or provided with a large reinforcing member having a large strength, the supporting strength is sufficiently large, and the bending is caused. There is little risk of deformation.

  As a result, in order to prevent bending deformation, the support structure is complicated, such as increasing the plate thickness of the members constituting the feeder, or providing a large reinforcing member having a large strength at the location where the connecting portion of the feeder is provided. It is possible to cope with a simple support structure without incurring.

  Also, the feeder is provided in a state of being displaced from the central position in the machine width direction of the cutting and conveying apparatus to the other end side in the machine width direction, and the hydraulic cylinder is formed by a vertical wall portion and a bottom surface portion located at one end side in the machine width direction.
