Description

[Detailed description of the invention] The present invention relates to a combine harvester in which a plurality of planted shell culm pulling devices are installed in parallel and a sensor is installed to detect the length of the shell culm at the time of hoisting. The purpose is to enable accurate detection of culm length while suppressing grain shedding as much as possible.

Next, embodiments of the present invention will be described in detail based on illustrative drawings.

A plurality of lifting devices 1 are installed in parallel in the horizontal direction to pull up the planted culms in the field, a reaping device 2 is used to reap the raised culms, and a machine is placed on the side of the machine while merging the cut culms. A horizontal conveying device 3 that conveys to one side, a vertical conveying device 5 that sends and receives the culm from the horizontal conveying device 3 and conveys it backwards while changing its posture to an almost horizontal position and delivering it to the feed chain 4. A threshing device 6 that threshes the husks while holding and transporting them, and a waste straw processing device 7 that shreds the waste straw after threshing or sends it to the field as long straw without shredding. , are sequentially connected to a traveling farm body equipped with a crawler traveling device 8, so that the combine harvester is configured to continuously harvest and process the planted culms in the field as it travels. .

The vertical conveyance device 5 is configured to swing and fix around the inclined axis 1 on the rear side thereof by the operation of a hydraulic cylinder 9, and the vertical conveyance device The conveyance start end side of the husk 5 is moved in the direction along the culm of the husk to change the length of husk culm supply to the threshing device 6, so-called handling depth.

A plurality of sensors S are provided at a predetermined interval in the vertical direction at the rear of one of the lifting devices 1a of the lifting devices 1. In addition to barking to detect the culm length under the action of the grain culm in the state,
This sensor S... and the hydraulic cylinder 9 are interlocked and connected to automatically change the handling depth based on the culm length.

The lifting claw rotation locus R1 of the lifting device 1a that lifts the culm whose culm length is detected by the sensor S... is the claw rotation trajectory of the other lifting device 1... The lifting device 1a is arranged so as to extend above R2, and the lifting device 1a applies the lifting action to the tip side end of the culm or its vicinity, thereby improving the detection accuracy by the sensor S. In addition, the other lifting device 1 is designed to apply the lifting action to near the lower end of the sugar in the culm, and to raise it to the highest possible position without causing granulation. It is.

In summary, the present invention provides the above-mentioned sensor S of the lifting device 1 in the government-registered combine harvester.
In order to raise and act on the culm, which is the object of detection, to the tip side end of the culm or near it,
Moreover, it is characterized in that it is designed to apply the remaining material to near the lower end of the tip of the culm.

In other words, the culm length is detected by the sensor S with respect to the culm that has been raised over the entire length of the culm so that only one pulling device 1a can be pulled up to the tip side end of the culm or close to it. The other lifting device 1 is capable of lifting the culm as close to the lower end of the sugar as possible, which does not affect the tips of the ears, to effectively pull up the culm without causing shedding. Overall, it was possible to detect the culm length with high accuracy while suppressing grain shedding due to culm lifting as much as possible.
