Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a harvester mainly configured to extract root vegetables such as ginseng and radish to perform leaf cutting.

[0002]

2. Description of the Related Art As a root crop harvesting machine, a harvesting transfer device for holding a foliage of root crops such as carrots and radishes planted in a field, pulling it obliquely upward at the rear of the fuselage, and suspending and transporting the harvest is provided. Provided on one side, provided with a leaf cutting device for cutting the foliage of root vegetables from the harvesting transport device, and provided with a collection unit for collecting root vegetables from the leaf cutting device behind the harvesting transport device, The present applicant has previously proposed a device provided with a foliage transfer device that discharges the cut foliage from the device to the outside of the fuselage. And in the previous proposal, the foliage conveying device was configured to discharge the cut foliage to the rear of the machine passing above the recovery unit.

[0003]

However, there is a case where the foliage transport device is obstructive in performing management of the collection section such as taking in and out of the harvest container from the boarding operation section on the side of the collection section. There was room for improvement in the manageability of the department. An object of the present invention is not only to facilitate the processing of root crops after harvesting, but also to facilitate the management of the collecting section from the boarding operation section without being hindered by the foliage transporting apparatus. The point conveyance device does not hinder the operation, and the discharge foliage does not hinder the running.

[0004]

According to a first aspect of the present invention, there is provided a harvesting transfer device which holds a foliage of root crops planted in a field, pulls it obliquely upward at the rear of the machine, and suspends and transports it. Provided on one side, provided with a leaf cutting device for cutting the foliage of root vegetables from the harvesting transport device, and provided with a collection unit for collecting root vegetables from the leaf cutting device behind the harvesting transport device, In a root crop harvesting machine provided with a foliage transfer device that discharges the cut foliage from the device to the outside of the machine, the root crop harvester is oblique across the front of the machine from the leaf cutting device to the other side of the machine opposite to the harvesting transfer device. And the foliage conveying device is arranged so as to convey the cut foliage.

[0005] A characteristic feature of the second invention is that a harvesting transfer device for holding a foliage of root crops planted in a field, pulling it obliquely upward at the rear of the machine, and suspending and transporting the crop is placed laterally on one side of the machine. Provide a leaf cutting device for cutting the foliage of root vegetables from the harvesting transport device, and provide a collection unit for collecting root vegetables from the leaf cutting device at the back of the harvesting transport device, and cut from the leaf cutting device. In a root crop harvesting machine provided with a foliage transport device that discharges foliage to the outside of the machine, an endless swivel band for gripping and transporting the foliage of the leaf cutting device and a foliage gripping transport of the foliage transport device of the leaf cutting device. Is formed by one endless rotating belt, and two loops before and after the leaf cutting device, and one loop disposed at the front of the fuselage on the other side of the fuselage on the opposite side to the harvesting transport device. Wrap the endless swivel belt in a triangular state, and move it from the leaf cutting device to the opposite side of the harvesting transport device. Body with other lateral side to a state of conveying the cut foliage diagonally across the machine body front lies in placing the leaves and stems conveying device.

[0006]

According to the structure of the first aspect of the present invention, when the cut foliage is transported obliquely from the leaf cutting device to the front of the fuselage on the opposite side of the harvesting transport device, the management of the recovery operation from the boarding operation unit to the lateral recovery unit is performed. The foliage transport device can be arranged so as not to be in the way,
The boarding driver can easily manage the collecting section without being adversely affected by the foliage transport device, and can arrange the foliage transport device so as not to hinder the operation. In addition, since the cut foliage is released to the outside of the fuselage at the front of the fuselage on the opposite side of the harvesting conveyance device, the foliage released earlier at the next harvesting travel is located at a remote position where harvesting has been completed. And the harvesting operation can be easily performed in a state where there is no adverse effect on running due to the released foliage.

Further, according to the configuration of the second aspect of the present invention, the leaf cutting device and the foliage transporting device share one endless rotary band for holding and transporting the foliage, so that the leaf cutting device and the harvesting transporting device can be combined. To arrange the foliage transport device in a state of transporting the cut foliage obliquely across the front of the fuselage on the other side of the fuselage other side, two rings before and after the leaf cutting device, and a transport device for harvesting The endless turning band is wound in a triangular state around one of the wheels arranged at the front of the body on the other side of the body and on the other side. As compared with the case where the endless rotating belts for holding and transporting the foliage of the foliage transporting device are separately provided, the number of the ring bodies and the number of the endless rotating bands can be reduced, and the transport configuration can be simplified.

[0008]

As a result, not only the treatment of the root crops after harvesting is facilitated by cutting and releasing the foliage, but also the harvest root crops in the collecting section by the boarding driver are easy to operate and the operation is further improved. Root crop harvesters can now be provided. In particular, according to the second aspect of the present invention, it is possible to provide a root crop harvesting machine that can reduce costs by simplifying the transport configuration and is excellent in economic efficiency.
