Description

  The present invention relates to an ordinary combine that is configured to throw all of the harvested cereals into a threshing apparatus and perform a threshing process.

  The ordinary combine harvester carries the threshing process by conveying all of the harvested cereal grains harvested by the harvesting part at the front part of the machine body to the threshing device at the rear of the machine body by the feeder. The grain obtained by the threshing process is stored in a grain storage unit provided side by side with the threshing apparatus, and waste straw generated in the threshing process is discharged to the outside from the rear of the threshing apparatus. The driving unit is provided side by side with the feeder, and the driving unit operates the cutting state of the cutting unit in a part of the cutting width from a gap between the driving unit and the feeder. The driver can see it (see, for example, Patent Document 1).

JP2013-128466A

  In the ordinary combine, the driver can visually confirm in a part of the cutting state of the cutting unit, but it is difficult to check the cutting state of the entire cutting width. Therefore, if the driver can visually recognize the situation behind the aircraft, the situation of the cut by the mowing unit, the condition of the waste discharged from the threshing device, and the like can be confirmed. In other words, it is possible to determine whether or not cutting residue has occurred from the state of the cut by the cutting unit, and whether or not soil or pebbles are mixed in the straw from the state of the discharge be able to.

  If explanation is added, for example, if a part to be inspected / repaired is not properly mounted at the time of maintenance work, there is a possibility that the defective part does not work well and the cutting work cannot be performed well. If the setting of the speed balance between the machine travel speed and the cutting speed by the cutting part is inappropriate, within the cutting width range, the cutting operation cannot be performed satisfactorily and all or some of the planted cereals are left uncut. May occur. If the set cutting height for the planted cereal by the reaper is too low, the reaping device may scrape the field scene and soil, pebbles, etc. may be mixed into the reaped cereal.

  If the driver can check the situation behind the machine body while continuing the driving operation in the driving section, it is possible to immediately determine the inappropriate work state as described above. However, in the above-described conventional configuration, it is difficult for a driver who performs a driving operation in the driving unit to visually recognize the situation behind the aircraft. If it is the structure which equips a driving | running part with a cabin, especially the confirmation of the condition behind the body is difficult.

  Therefore, it is conceivable to provide an imaging device (camera) that captures the back of the aircraft and confirm the situation behind the aircraft based on an image captured by the imaging device. In that case, it is desirable to be able to appropriately capture the situation behind the aircraft.

The characteristic configuration of the ordinary combine according to the present invention is as follows:

There is a possibility that the situation of the discharge discharged from the threshing device cannot be properly photographed. On the other hand, when the imaging device is provided at a position on the opposite side to the central position in the cutting width direction with respect to the central position in the horizontal width direction of the threshing device when viewed from the front-rear direction of the machine body, There is a possibility that good shooting cannot be performed.

  Therefore, the imaging device is provided at a position located between the center position in the cutting width direction of the reaping portion and the center position in the width direction of the threshing device in the longitudinal direction of the machine body. By doing so, it becomes possible to photograph the state of the cut after the cutting is performed by the cutting unit over substantially the entire width of the cutting width range. And since an imaging device is provided in the location located in the upper part rather than the discharge port of the threshing device in the rear part of an airframe, it is easy for an imaging device to check a discharge state in an appropriate position along a width direction to a discharge port. As a result, it is possible to photograph the state of the discharge discharged from the discharge port of the threshing apparatus over substantially the entire width in the lateral direction.
