DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a harvesting section of a root crop harvesting machine configured to pull out root crops such as carrots and radishes planted in a field, cut and collect the leaves.

[0002]

2. Description of the Related Art As the root crop harvester described above, for example, as shown in Japanese Utility Model Application Laid-Open No. 5-70226, the foliage of root crops such as ginseng and radish planted in a field is sandwiched between left and right transport belts. Harvesting transporting device that pulls out from the rear of the machine diagonally upward and transports it in a suspended manner, a leaf cutting device that cuts the foliage of root crops from the harvesting transporting device, and left and right guide rollers with respect to the transport belt are alternately positioned. A position setting transfer device that abuts on the upper end of the root vegetables suspended by the transfer intermediate portion of the harvest transfer device that is dispersed and arranged in a state in which the harvesting transfer device is brought into contact with the upper end,
There has been proposed a device provided with a collecting unit for collecting root vegetables from a leaf cutting device. Conventionally, in order to allow a modest clamping force which is not so strong as to allow for the lowering of the foliage by the positioning transport device in contact with the upper end of the root vegetables, the transport is performed in the transport intermediate portion of the harvest transport device. The left and right guide rollers are alternately arranged with respect to the belt, and the vertical position of the intermediate transfer portion of the harvesting transfer device is maintained only by the engagement between the transfer belt and the guide roller.

[0003]

However, since the left and right guide rollers are alternately arranged with respect to the conveyor belt, the conveyor belt may come off from the guide rollers when the foliage is lowered by the positioning conveyor. ,
Looseness of the conveyor belt causes insufficient lifting of the root crops to the conveyor for positioning, which tends to cause irregular cutting of the foliage by the leaf cutting device. There was room for improvement from the aspect of improving the performance.

[0004] It is an object of the present invention to provide a harvesting transporting device in which the intermediate position of the harvesting transporting device is provided with an appropriate clamping force for allowing the foliage to be lowered by the positioning transporting device contacting the upper end of the root vegetables. An object of the present invention is to surely prevent the transport belt from being loosened due to the lowering of the foliage by the determining transport device.

[0005]

A characteristic feature of the present invention is that a harvesting transporting apparatus is provided in which a foliage of root crops planted in a field is held by a left and right transport belt, pulled out obliquely upward at the rear of the machine, and suspended and transported. And a leaf cutting device that cuts the foliage of root crops from the harvesting transport device, and a transport intermediate portion of the harvesting transport device that is distributed and arranged in a state where the right and left guide rollers with respect to the transport belt are alternately positioned. Root crop harvesting with a positioning transport device that contacts the upper end of the suspended root vegetables as the harvest transport device raises it, and a collection unit that collects root vegetables from the leaf cutting device In the machine, a belt support member that acts in a state that prevents pulling down by root vegetables with respect to the conveyance intermediate portion of the harvesting conveyance device, in a state in which the left and right members that individually act on the conveyance belt face each other. Lies in the partially disposed in the vicinity of the front end of 置定 Me conveying device.

[0006]

In other words, the left and right belt supporting members acting separately on the conveyor belt are arranged near the front end of the positioning conveyor to prevent the harvesting conveyor from being pulled down by the root crops in the middle of the conveyor. By this, it is possible to reliably prevent the transport belt from being loosened due to the lowering of the foliage by the transport device for positioning, and to surely realize the pulling of the root vegetables with respect to the transport device for positioning, so that the foliage by the leaf cutting device is realized. Cutting can be aligned. And, by partially disposing the belt support member near the front end of the positioning transfer device, it is not so strong that the foliage can be lowered by the positioning transfer device in contact with the upper end of the root vegetables. The clamping force can be applied to the intermediate transfer portion of the harvesting transfer device without being damaged by the belt support members arranged opposite to each other.

[0007]

As a result, while a moderate holding force which is not so strong is obtained by the transfer intermediate portion of the harvesting transfer device,
It has become possible to provide a root crop harvester that can reliably prevent the transport belt from being loosened due to the lowering of the foliage by the positioning transport device, and which is more excellent in the foliage cutting function.
