Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a combine harvester equipped with a handling depth sensor for detecting the handling depth of grain culms on a grain culm transporting route for transporting cut culms to a threshing section. The present invention relates to a handling depth detection device.

[Prior Art] Conventionally, as shown in Japanese Utility Model Laid-Open No. 58-125943 and Japanese Patent Laid-Open No. 60-168318, a handling depth of grain culms is provided on a grain culm transporting route for transporting cut grain culms to a threshing section. A handling depth sensor is provided, and the handling depth sensor is attached to the sensor frame that supports the transporting clamping rod that guides the tip end side of the grain culm, and the handling depth is sandwiched between the grain culm transport paths. There was a technique of disposing a tip guide cover on the opposite side of the sensor.

[Problems to be Solved by the Invention] In the prior art, the sensor frame is formed by a U pipe (connecting rod) that connects and supports the transfer chain and the transfer tine, or the sensor frame is formed by a pinching arm. Since the sensor frame was connected to the cutting frame via the upper transport mechanism for transporting the tip side of the cut grain culm, the sensor frame is formed in a U shape so as to cross the grain culm transport path upper side. In addition, there is a problem in that the strength for supporting the handling depth sensor cannot be easily ensured, and the assembling accuracy cannot be easily improved.

[Means for Solving the Problems] Therefore, the present invention is provided with a handling depth sensor for detecting the handling depth of grain culms on the grain culm transporting route for transporting cut grain culms to the threshing section, and the tip of the grain culm is provided. The handling depth sensor is attached to the sensor frame that supports the transporting clamping rod that guides the side, and the tip guide cover is provided on the opposite side of the handling depth sensor with the grain culm transport path interposed. In the combine handling depth detection device, the sensor frame is fixed in the middle of the raising pipe that is erected on the cutting frame on the left side of the machine on which the feed chain is installed, and the lifting rod and the holding rod are handled through the sensor frame. It is characterized by mounting a depth sensor.

"Operation" Therefore, the sensor frame can be supported on the mowing frame without traversing the grain culm transportation path, and the sensor frame can be linearly formed by using the raising pipe to simplify the shape of the sensor frame. It is possible to easily secure the supporting strength of the pinching rod and the handling depth sensor, and to easily improve the assembling accuracy.
