Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a harvesting machine constructed so as to mainly extract root vegetables such as carrots and radishes and perform leaf cutting.

[0002]

2. Description of the Related Art Japanese Patent Application No. 4-15 is used as a root vegetable harvester.
As shown in No. 7126, a harvesting transporting device that sandwiches the foliage of root vegetables such as carrots and radishes planted in the field and pulls it diagonally upward at the rear of the aircraft and hangs it for transportation is located on one side of the aircraft. 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 cutting stems and leaves from the leaf cutting device are provided. The present applicant has previously proposed a root vegetable harvesting machine provided with a foliage transporting device for discharging parts to the outside of the machine body. Then, in the previous proposal, the foliage portion conveying device is configured so as to discharge the cut foliage portion through the upper portion of the collecting portion to the rear of the machine body.

[0003]

However, there is a case where the foliage transporting device interferes with the management of the collection section such as loading and unloading of the harvest container from the boarding operation section on the side of the collection section, and the collection section may be an obstacle. There was room for improvement in the controllability of the department. The object of the present invention is not only to facilitate the treatment of root vegetables after harvesting, but also to facilitate the management of the recovery section from the boarding operation section without being obstructed by the foliage section conveying device, and furthermore, the foliage section. The point is that the transport device does not hinder the operation and the discharged foliage does not hinder the running.

[0004]

In order to achieve the above object, the present invention provides a harvesting transport device for sandwiching and transporting a foliage portion of a root vegetable planted in a field by pulling it obliquely upward at the rear of the transporter. Provided on one lateral side, a leaf cutting device for cutting the foliage of the root vegetables from the harvesting transport device is provided, and a recovery unit for collecting the root vegetables from the leaf cutting device is provided at the rear of the harvesting transport device. In a root vegetable harvester equipped with a foliage transporting device that discharges the cut foliage from the outside of the machine, the harvesting unit consisting of the harvesting transporting device, leaf-cutting device and foliage transporting device is shaken around the left and right fulcrum. It is configured to be movable up and down, and the foliage transporting device is arranged in a state of transporting the cutting foliage part diagonally from the leaf cutting device to the front part of the machine side on the opposite side of the machine side opposite to the machine side, The cutting and foliage parts transferred by this foliage transfer device 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-mentioned characteristic structure, when the cutting and foliage portion is obliquely conveyed from the leaf cutting device to the front part of the machine opposite to the harvesting conveyance device, it does not hinder the management from the boarding operation part to the side recovery part. Thus, the foliage transporting device can be arranged, the boarding driver can easily manage the recovery unit without being adversely affected by the foliage transporting device, and the foliage transporting device can be arranged so as not to disturb the operation. In addition, since the cutting foliage is discharged to the outside of the machine at the front of the machine opposite to the harvesting conveyor, the foliage that was previously discharged at the next harvesting run will be a distant position that has already been harvested. It is possible to easily carry out the harvesting work without being stepped on, and in a state where the discharged foliage portion does not adversely affect traveling.

Since a chute that guides the cut foliage transferred by the foliage conveying device to the outside of the machine is installed below the foliage conveying device, the foliage that falls during the conveyance is also included. It will be possible to reliably discharge it outside the fuselage. Then, when the harvesting section consisting of the harvesting transporting device, the leaf cutting device, and the foliage transporting device is allowed to move up and down according to the ups and downs of the field, the chute is also configured to move up and down as a unit. The positional relationship between the chute and the foliage conveying device will not change regardless of the elevation of the section,
It becomes possible to maintain the above-mentioned positive discharge action.

[0007]

As a result, not only the processing of root vegetables after harvesting is facilitated by cutting and releasing the foliage, but also the management of harvested root vegetables in the collecting section by the boarding driver is easy and the operation is easy, and We were able to provide a much superior root vegetable harvester that can reliably discharge the cut stems and leaves regardless of the lifting operation.
