Description

  The present invention relates to a combine, and more particularly, to a combine having a large number of cutting lines such as 8-cutting.

  Combines with a large number of cutting lines, such as 8-cutting, increase the cutting width (width) by the cutting part and exceed the regulation width when traveling on the road. In such a case, there is a problem that the vehicle cannot travel on the road as it is.

  Conventionally, for example, in an 8-row combine combine, front and rear frames on both sides located at both ends of the cutting width direction among a plurality of front and rear frames extending in the front and rear direction of the machine body in order to support a plurality of weeds of the cutting unit. There is a configuration in which the lateral width can be accommodated within a predetermined width by switching to the separated state in which the long cutting blade extending over the entire width in the cutting width direction is removed while being removed (see, for example, Patent Document 1). .

JP 2009-278902 A

  In the above-described conventional configuration, in the normal use state where the number of cutting lines is large, the planted cereals for 8 lines can be cut at a time, and the harvesting work efficiency can be improved. However, for example, when running on the road, etc., in the separated state where a part of the cutting part is separated and the lateral width is narrowed, not only the front and rear frames at both ends of the cutting width direction but also the cutting blades are removed. After switching to the state, cutting work was impossible.

  Therefore, it has been desired to perform the cutting operation not only in a wide normal use state but also in a narrow separated state.

The characteristic configuration of the combine according to the present invention is as follows:
The front part of the fuselage is equipped with a harvesting part that harvests multiple sown cereal grains,
The cutting unit includes a plurality of raising devices corresponding to the number of cutting lines, a cutting device that cuts the planting cereal stock, and a transport device that transports the cutting cereal toward the rear of the machine body, In the middle of the cutting width direction, it is divided and formed into one side cutting part divided body and the other side cutting part divided body,
Switch between the normal use state in which the one-side cutting part divided body is arranged in series with the other-side cutting part divided body and the separated state in which the one-side cutting part divided body is separated from the other-side cutting part divided body and removed outside the machine. Provided freely,
Power from the machine body side is transmitted to the pulling device on the other side cutting portion divided body side, and in the normal use state, the other side cutting portion is connected to the pulling device on the one side cutting portion divided body side. In the point which is comprised so that motive power may be transmitted from the said raising apparatus by the side of a division body.

  According to the present invention, the cutting part can be divided into the one-side cutting part division body and the other-side cutting part division body at a midway position in the cutting width direction, and the one-side cutting part division body and the other-side cutting part division. Each body has a pulling device, a cutting device, and a conveying device.

  In the transmission structure that transmits the power from the machine body to the mowing unit, the cutting device and the conveying device transmit power from the lower part of the rear part of the machine body where the mowing part is connected to the machine through the lower side of the conveying path of the harvested grain It is possible to make it.

If all the pulling devices are provided integrally with the cutting unit without dividing the cutting unit, all the pulling devices via the transmission shaft extending in the lateral direction along the upper part of the pulling device. Power transmission is possible.

  However, when the cutting part is configured to be divided, the power must be transmitted from both ends of the cutting width direction toward the transmission shaft located at the top of the device. Since the operation part is provided at the location, it is not possible to provide a transmission structure for transmitting power from both ends of the cutting width direction.

  Therefore, in the normal use state where the one-side cutting part division is aligned with the other-side cutting part division in a series in the cutting width direction, the pulling device on the one-side cutting part division side is raised to the pulling device on the one-side cutting part division side. Power is transmitted from the device.

  In the normal use state, first, the power on the airframe side is the other power by transmitting the power from the pulling device on the other side of the cutting part divided body side to the pulling device on the one side cutting part split body side. It is transmitted to the pulling device on the side of the side cut part division, and transmitted from the pulling device on the side of the other side cut part division to the pulling device on the one side cut part division. As a result, the raising device can be driven satisfactorily in each of the one-side cutting part division body and the other-side cutting part division body.

  In the separated state, the one-side cutting part divided body is separated from the other-side cutting part divided body and removed outside the machine, but the power on the machine side is transmitted to the pulling device on the other side cutting part divided body side. Remains as it is, so that even in this separated state, the raising device can be driven satisfactorily.

  Therefore, the cutting operation can be performed not only in the normal use state in which the cutting width (horizontal width) such as the eight strips is set to be large but also in the separated state where the horizontal width is such that the road traveling can be performed. It was.
