  Crops are planted in a state in which a plurality of crop rows are formed in a state where they are lined up at intervals. The crop harvester harvests crops planted in the field while driving the aircraft along one crop row. Among the crop rows in the unharvested area, The crops in the most harvested area side are harvested and harvested while the crops are pulled out from the field at the pull-out section. In this way, harvesting can be performed in a state where the crops in the unharvested area are not stepped on by the traveling devices on both the left and right sides provided in the traveling machine body.

Also, the other end in the width direction of the aircraft is taken into consideration in view of the left and right weight balance of the aircraft by adopting a configuration in which the crop that has been transported rearward by the extraction unit and the leaf portion is cut is conveyed to the other end in the width direction of the aircraft. The crops are collected at the collection section on the side.
In addition, as a processing form of the crop conveyed to the other end side in the horizontal direction of the machine body, for example, in a harvesting operation in the next work process in an adjacent crop row, the cropping device is not stepped on by the traveling device. However, there is a case in which an operation mode is employed in which the crop is discharged to the field from the outside of the machine body on the other end side in the machine body width direction.

  However, in the above-described conventional configuration, the leaf portion separated from the crop is transported toward the rear of the extraction portion and then discharged from the rear outer side of the machine body to the outside of the machine. was there.

That is, since the leaf portion is discharged to the field in a state where it is located on the rear side of the extraction portion, that is, on one end side in the horizontal direction of the machine body, at the time of harvesting work in the next work process in the adjacent crop row It exists in the position near the crop line to be harvested.
As a result, when the harvesting operation is performed in the next work process, there is a leaf portion released to the field near the crop row to be harvested. There was a risk.

  By the way, since the leaves released to the field are not generally harvested, it is considered that there are few problems even if they are stepped on by the traveling device provided on the aircraft, but they were discharged to the field, for example. The leaves may be reused as livestock feed, and the conventional configuration has the following disadvantages in such a case.

  That is, in the conventional configuration, as described above, the leaf portion released to the field is present at a position close to the crop line to be harvested in the harvesting operation in the next work process. There is a risk of stepping on the leaves released to the field during the harvesting operation in the process by the traveling device provided in the aircraft. Thus, when the leaf part is stepped on by the traveling device, there is a disadvantage that the leaf part discharged to the farm field cannot be used as livestock food.

  The object of the present invention is to discharge the leaf part to the field as the aircraft is traveling, but the discharged leaf part is entangled with the extraction part, obstructing the harvesting work, the leaf part cannot be used as bait, etc. This is to provide a crop harvesting machine that can eliminate the disadvantages and can perform harvesting work well.

At the time of the harvesting work in the next work process in the adjacent crop row, the leaf portion discharged to the field is present at a position away from the crop row to be harvested to the other side in the horizontal direction of the machine body. .

  As a result, during the next harvesting process in the adjacent crop line, the leaves discharged to the field are less likely to get entangled with the extraction part and obstruct the harvesting work. It will be good.

  In addition, since the leaf portion discharged to the field is present at a location distant from the crop row to be harvested to the other end in the lateral width direction of the aircraft, it was provided in the aircraft during the harvesting work in the next work process. There is little possibility that the traveling device will step on the leaves that are discharged to the field. That is, the discharged leaf portion is not damaged by the traveling device, and can be favorably used as livestock food.

  Therefore, the leaf part is discharged to the field as the aircraft travels, but the disadvantage that the discharged leaf part gets entangled with the extraction part and obstructs the harvesting work or the leaf part cannot be used as bait is eliminated. As a result, it has become possible to provide a crop harvester that can perform harvesting work well.

  In addition to the first characteristic configuration, the second characteristic configuration of the present invention is a discharge unit that sequentially drops and discharges the crop conveyed to the other end side in the horizontal direction of the machine body by the crop conveyance unit as the machine body travels. And the leaf transport device is configured to discharge the leaf at or near the fall release position of the crop by the discharge unit.

  According to the second characteristic configuration, as the harvesting operation is performed as the machine travels, the crops transported to the other end side in the lateral width direction of the machine by the crop transport unit are sequentially released and released to the field by the discharge unit. The Then, the leaf portion transported to the other end side in the lateral width direction of the body by the leaf portion transporting device is discharged out of the device at the position where the crop is released or released in the field.

  As described above, the position where the leaf part is discharged is the position where the crop is discharged or a position in the vicinity thereof, so that the impact can be reduced by the leaf part when the crop falls to the field. It is possible to reduce the risk of damage when falling.

  In addition to the second feature configuration, the third feature configuration of the present invention is a discharge guide in which the discharge unit transports the crop transported to the other end side in the lateral width direction of the machine body toward the lower rear side of the machine body. However, it is in the point comprised with the inclination guide body which falls and discharge | releases to a farm field.

  According to the third feature configuration, the crop conveyed to the other end side in the horizontal direction of the machine body by the crop conveyance unit is guided to flow downward toward the lower rear side of the machine body by the inclined guide body and is dropped and released to the field. Become. In other words, as the aircraft travels, the crops are released while guiding the flow down toward the rear side of the aircraft, that is, the direction opposite to the aircraft traveling direction, so the momentum when the crops fall to the field will be reduced. Can be released to the field with as little impact as possible.

  In addition, the leaf part cut by the leaf part cutting part is transported to the other end side in the lateral direction of the machine body by the leaf part transport device and discharged outside the machine. It can also be received, and the impact of dropping can be further reduced.

  Therefore, the crop can be prevented from being damaged by the impact of falling on the field, and the harvesting operation can be performed in a good state.

  According to a fourth feature configuration of the present invention, in addition to any one of the first feature configuration to the third feature configuration, the leaf transport device is configured by a belt conveyor that is driven to rotate around a longitudinal axis of the machine body. There is in point.

  According to the fourth feature configuration, since the leaf portion conveying device is configured by a belt conveyor that is driven to rotate around the longitudinal axis of the machine body, for example, the leaf portion contains a lot of moisture. However, it can be forcibly transported to the other end side in the lateral direction of the machine body by the belt conveyor, and can be discharged to the outside from the transport terminal portion.
