  The present invention relates to a corn harvester, and more specifically, a harvesting device that harvests a corn tuft having a large number of seeds inside a foliage from a planted crop as the aircraft runs, and the harvesting device harvests the corn harvester. The present invention relates to a corn harvester provided with a feeder that transports the corn tufts upward toward the rear of the machine body and discharges the corn tufts from a discharge port formed at a conveyance end portion.

  In a conventional corn harvester, a corn tuft with a large number of seeds inside a foliage is harvested by a harvesting device, and the corn tuft is transported upward and rearward by a feeder. There was what was made to store with a tank (for example, refer to patent documents 1).

JP 2013-188143 A

  In the above conventional configuration, the corn tuft obtained by the corn harvester is provided with a large number of seeds inside the foliage and cannot be directly used for food. It is necessary to peel off the leaves. In this way, peeling the foliage from the corn tufts is a cumbersome and cumbersome task, so that the corn harvester can also peel off the foliage with the harvesting work. It was hoped that.

  And when mounting the peeling apparatus for performing a peeling operation | work to a corn harvester, it is necessary to supply the motive power from an engine with respect to the peeling apparatus. In addition, the engine is generally installed at a low position on the machine body in a state of being mounted on the machine frame, and is peeled off in order to perform a skinning operation after being transported to a high position in the rear upper part by the feeder. The device will be installed at a high position. As a result, the distance between the engine and the skinning device is greatly separated. Therefore, if power from the engine is supplied directly to the skinning device, a dedicated transmission mechanism for driving the skinning device becomes a major factor. The transmission structure may be greatly complicated.

  Therefore, there has been a demand for a corn harvester capable of performing a skinning operation for stripping off the foliage accompanying the harvesting operation while avoiding a significant increase in the transmission structure.

A characteristic configuration of a corn harvester according to the present invention is a harvesting device that harvests a corn tuft having a large number of seeds inside a foliage from a planted crop as the aircraft runs,
A feeder that conveys the corn tufts harvested by the harvesting device toward the upper rear of the machine body and discharges them from the discharge port formed in the conveyance end portion;
A skinning device for stripping the foliage of the corn tufts discharged from the outlet;
In addition to transmitting the power of the engine mounted on the airframe to a feeder drive unit for driving the feeder, a power transmission unit for transmitting power from the feeder drive unit to the skinning device is provided. .

As a result, the corn after the foliage has been stripped from the corn tufts can be obtained as the final harvest object.

  The power of the engine mounted on the airframe is transmitted to the feeder driving unit via the feeder transmission mechanism, and the feeder is driven. The engine power transmitted to the feeder drive unit is transmitted from the feeder drive unit to the skinning device via the power transmission unit.

  In other words, the power of the engine is not transmitted directly to the skinning device, but the power transmitted to the feeder drive unit using the existing power transmission mechanism for the feeder is used effectively to the skinning device. To transmit power. And since the skinning device is in a position close to the feeder drive unit, the power transmission unit that transmits power from the feeder drive unit to the skinning device is more powerful than that that directly transmits engine power to the skinning device. It can be configured with a small and simple transmission mechanism.

  Accordingly, it has become possible to provide a corn harvester capable of performing a skinning operation for stripping off the foliage accompanying the harvesting operation while avoiding a significant increase in the transmission structure.
