For example, in rice cultivation, a field management system has been proposed to improve harvesting by collecting and accumulating various field work data. In the field management system, one field is divided into a number of areas, and field operation data such as harvest data (harvest amount and quality) by combine is collected and accumulated corresponding to each area of the field. Improvement of seedling planting, sowing and tillage etc. will be carried out in the year.

The reaping unit provided in the front part of the machine body and having a cutting width capable of cutting crops with five or more planting lines and the reaping unit provided alongside the cutting width direction of the cutting unit, When a conventional technique for detecting the presence of a crop is adopted in a combine provided with three or more transport devices for transporting the crop to the rear merge point, the presence of the crop in the transport route after the merge point is detected. Since it will be detected by the crop detection sensor, when performing mowing in the multi-row mowing mode, the result of detection by the crop detection sensor shows that the crop that has been cut invades any range in the cutting width direction of the mowing part. I can't get information about what I'm doing. In addition, the crop detection sensor is the same when performing mowing in the range of only one end side in the mowing width direction of the mowing section and mowing in the range of only the other end side in the mowing width direction of the mowing section. This is the same as the detection function.
In other words, it is not possible to collect the harvest data corresponding to each area obtained by dividing the field into a number of areas, and it is not possible to obtain a good field management system.

The present invention is provided with a mowing unit having a mowing width capable of mowing 5 or more rows, and three or more transporting devices for transporting a harvested crop by the mowing section to a confluence point at the rear, while performing multiple row mowing. Information that allows you to know in which part of the mowing part the mowing part has invaded even when performing it or when mowing only part of the mowing part in the mowing direction. To provide a combine that can obtain

The combine according to the present invention is
A mowing section provided in the front portion of the machine body and having a mowing width capable of mowing crops of five or more planting articles, and a mowing section provided side by side in the mowing width direction of the mowing section and mowed by the mowing section. Three or more transport devices for transporting the crop to a rear confluence point, a crop detection sensor provided on each of the transport routes of the three or more transport devices to detect the presence of the crop in the transport route, and the crop detection A cutting condition detection unit that calculates, in the cutting width direction, a range of the cutting unit in which the cut crop has entered based on a detection result of the sensor.

According to the present configuration, the harvested state detection unit calculates the harvested crops in the cutting width direction based on the detection results of the crop detection sensors provided on the transport routes of the three or more transport devices. Since the range of invasion is calculated, the mowed crop can be cut in the cutting width direction of the mowing section, even when performing multi-row cutting or mowing in only a part of the mowing section. You can get information to know the range of the invasion.

In the present invention, it is preferable that the crop detection sensor is a rocking bar which is brought into a detection state by being rocked by coming into contact with a crop.

According to this configuration, since the crop detection sensor can be obtained with a simple structure, it is possible to inexpensively obtain information about the crop invasion range in the cutting unit.

In the present invention, the carrying device is provided above the stock-source-side transport unit and a stock-source-side transport unit that sandwiches and transports the stock-source-side portion of the harvested crop, and the tip-side portion of the harvested crop is locked and transported. It is preferable that the swing bar is provided at a position corresponding to the front part of the transport device in a plan view.

According to this configuration, the rocking bar acts on the harvested crop before the transport distance by the stocker side transport section and the tip side transport section becomes long, so that the detection result can be obtained early.

In the present invention, it is preferable that the rocking bar is provided between the stocker side transport section and the tip side transport section in the vertical direction.

According to this configuration, since the mud jumped up from the ground does not easily adhere to the rocking bar, and the cut leaves do not easily adhere to the rocking bar from above, the mud and cut leaves cause the rocking bar to stick. Easy to avoid malfunction.

In the present invention, it is preferable that a lower cover that covers the tip side transporting section from below is provided, and that the swing bar is supported on the back surface side of the lower cover.

According to this configuration, since the lower cover is used as the support member of the swing bar, it is not necessary to provide a special special support member, and the swing bar can be easily equipped.

In the present invention, in a state in which two or more crop detection sensors are detecting the crop, a position is provided between the crop detection sensor detecting the crop and the crop detection sensor detecting the crop. When the crop detection sensor does not detect a crop, it is preferable that the cutting condition detection unit treats the detection result of the crop detection sensor as abnormal data.

According to this configuration, when an abnormality such as a failure of the crop detection sensor occurs, it is possible to immediately know the abnormality occurrence by handling the data by the cutting condition detection unit, so that the operation can be promptly responded to by the abnormality occurrence. Can be taken to.

In the present invention, when the automatic control of the threshing device for threshing a harvested crop is in the ON state, when the crop detection sensor in any one of the three or more transport devices detects a crop, Suitably, the automatic control is adapted to be activated.

According to this configuration, the crop detection sensor that detects the harvested crop in front of the threshing device starts the automatic control of the threshing device, so that the threshing device is automatically controlled without timing delay.
