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 the above root crop harvesting machine, Japanese Patent Application No. 4-15 / 1990
As shown in No. 7126, a harvesting transporting device that holds the foliage of root vegetables such as carrots and radishes planted in a field, pulls it obliquely upward at the rear of the fuselage, and suspends and transports the harvest is provided on one side of the fuselage. And a leaf cutting device for cutting the foliage of the root vegetables from the harvesting transport device is provided, and a collecting unit for collecting the root vegetables from the leaf cutting device is provided behind the harvesting transport device, and the cut foliage from the leaf cutting device is provided. The present applicant has previously proposed a root vegetable harvesting machine provided with a foliage conveying device that discharges the portion to the outside of the machine body. 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 the root vegetables after harvesting, but also to easily manage the collection unit from the boarding operation unit without being hindered by the foliage transport device, The transport device does not hinder the operation, and the discharge foliage does not hinder the running.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a harvesting transfer device for holding a foliage of a root vegetable planted in a field, pulling it obliquely upward at the rear of the machine and suspending and transporting the harvested machine. A leaf cutting device is provided on one side, and a leaf cutting device is provided for cutting the foliage of root vegetables from the harvesting transport device, and a collecting unit for collecting root vegetables from the leaf cutting device is provided behind the harvesting transport device, and the leaf cutting device is provided. In a root vegetable harvesting machine provided with a foliage transfer device that discharges cut foliage from the outside of the machine, a harvesting unit including a harvesting transfer device, a leaf cutting device, and a foliage transfer device is swung around a left-right fulcrum. It is configured to be able to move up and down, and the foliage transport device is arranged in a state in which the cutting foliage is transported obliquely from the leaf cutting device to the front of the fuselage on the other side of the machine opposite to the harvesting transport device, The cut foliage transferred by this foliage transporter is used as a machine. The chute leading to the outside, extending below the foliage conveying device, and is characterized in that are equipped in a state of being swung elevating integrally with the harvesting unit.

[0005]

According to the above feature, when the cut foliage is transported obliquely from the leaf cutting device to the front of the body opposite to the harvesting transporting device, it does not hinder the management of the recovery unit from the boarding operation unit to the side. The foliage transfer device can be arranged as described above, and the boarding driver can easily execute the management of the collection unit without being adversely affected by the foliage transfer device, and can further arrange the foliage transfer 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.

[0006] A chute that guides the cut foliage transferred by the foliage transporting device to the outside of the machine is provided so as to extend below the foliage transporting device. It will be possible to discharge the waste out of the fuselage without leaving any residue. Since the harvesting unit including the harvesting transport device, the leaf cutting device, and the foliage transport device can be moved up and down in accordance with the ups and downs of the field, the chute is also configured to move up and down integrally. The positional relationship between the shoot and the foliage transport device does not change regardless of the elevation of the part,
The above-described reliable discharge operation can be maintained.

[0007]

As a result, not only the processing of the root vegetables after harvesting is facilitated by cutting and releasing the foliage, but also the harvesting root vegetables in the collecting section by the boarding driver are easy and the operation is easy. A more excellent root vegetable harvesting machine capable of reliably discharging the cut foliage outside the machine regardless of the lifting operation was provided.

[0008]
