The root vegetable harvester shown in Patent Document 1 is provided with a transport device as a pinch transport device.

Japanese Unexamined Patent Publication No. 2018-50575

In the above-mentioned root vegetable harvester, if the foliage portion is not properly sandwiched by the sandwiching and transporting device, the root vegetables are not harvested and remain in the field. So-called harvest omissions occur. In addition, even if a planting part that raises the foliage of the root vegetable to be harvested and supplies it to the sandwiching transport device is provided, the foliage part is widened or collapsed, causing the planting part to cause a defect or a supply failure to the sandwiching transport device. If there is, there will be a harvest omission.

The present invention provides a root vegetable harvester in which harvest omission is unlikely to occur.

The root vegetable number harvester according to the present invention
A pinch transport device that pulls out the root vegetables from the field by pinching and transporting the foliage of the root vegetables to the rear and upper part.
A weeding portion provided in front of the sandwiching and transporting device, which raises the foliage of the root vegetable to be harvested and supplies it to the sandwiching and transporting device, is provided. The first weed body that rises backward from the front end of the weed body toward the start end of the sandwiching and transporting device and is extended sideways, and the weed body below the rear part of the first weed body. It has a second weed stalk that rises backward toward the start end of the sandwiching and transporting device and is extended sideways.

According to this configuration, the stems and leaves of the root vegetables to be harvested and the stems and leaves of the root vegetables not to be harvested are weeded by the weeds, and the stems and leaves of the root vegetables to be harvested are the first and second stalks. Since the root vegetables are scooped up and brought toward the pinching transport device, the root vegetables can be harvested in a state where they are not easily left in the field because the stems and leaves are accurately pinched by the pinching transport device regardless of the spread or collapse of the foliage.

In the present invention
In the side view, it is preferable that the rear part of the first sprouting rod and the second sprouting rod are parallel to each other.

According to this configuration, since the foliage portion is less likely to be clogged between the first sprouting rod and the second sprouting rod, the root vegetables to be harvested can be smoothly supplied to the sandwiching and transporting device.

In the present invention
In a plan view, it is preferable that the rear portion of the first sprouting rod and the second shunting rod overlap.

According to this configuration, the foliage portion smoothly moves toward the sandwiching and transporting device along the first sprouting rod and the second sprouting rod, so that root vegetables are less likely to be clogged.
