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 that root vegetables such as carrots and radish can be extracted and cut into leaves.

[0002]

2. Description of the Related Art As the root vegetable harvesting machine, a harvesting transporting device for holding and transporting the foliage of root vegetables such as carrots and radishes planted in the field and pulling them obliquely upward at the rear of the machine and transporting them by the side of the machine is available. Installed on one side, a leaf cutting device is provided for cutting the foliage of root vegetables from the harvesting transport device, and a collection unit for collecting root vegetables from the leaf cutting device is provided behind the harvesting transport device. The present applicant has previously proposed a foliage conveying device that discharges the cut foliage from the device to the outside of the machine. 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 are cases where the foliage transporting device interferes with the management of the harvesting section such as loading and unloading of the harvest container from the boarding operation section on the side of the harvesting section. 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 unit from the boarding operation unit without being obstructed by the foliage transporting device, and yet the foliage. The part-conveying device does not hinder the operation, and the discharged foliage part does not hinder the running.

[0004]

Means for Solving the Problems The characteristic configuration of the first aspect of the present invention is to provide a harvesting transporting device that holds a foliage portion of root vegetables planted in a field, pulls it obliquely upward at the rear of the fuselage, and hangs and transports it. Installed on one side, a leaf cutting device is provided for cutting the foliage of root vegetables from the harvesting transport device, and a collection unit for collecting root vegetables from the leaf cutting device is provided behind the harvesting transport device. In a root vegetable harvester equipped with a foliage transporting device that discharges the cut foliage from the device to the outside of the aircraft, the leaf cutting device is diagonally across from the leaf cutting device to the other side of the aircraft on the side opposite to the harvesting transportation device. The foliage portion conveying device is arranged so that the cut foliage portion is conveyed.

Further, the second aspect of the present invention is characterized in that a harvesting transporting device for holding the foliage of root vegetables planted in a field, pulling it obliquely upward at the rear of the machine, and suspending and transporting it is lateral to one side of the machine. Provided, a leaf cutting device for cutting the foliage of root vegetables from the harvesting transport device, and a collection unit for collecting root vegetables from the leaf cutting device behind the harvesting transport device, cutting from the leaf cutting device In a root crop harvester equipped with a foliage conveying device that discharges foliage to the outside of the machine, an endless rotation band for foliage-holding conveyance of a leaf-cutting device and an endless rotation belt for foliage-holding conveyance of a foliage-transporting device. Is formed by a single endless swivel belt, and two wheels are attached to the front and back of the leaf-cutting device, and one wheel is placed on the front side of the machine on the other side of the machine opposite to the harvesting conveyor. Wrap the endless swivel belt in a triangular state on the opposite side of the leaf cutting device from 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 cutting stems and leaves are conveyed obliquely from the leaf cutting device to the front part of the machine body on the side opposite to the harvesting conveyance device, the boarding operation part manages the side recovery part. You can arrange the foliage transport device so that it does not get in the way,
The boarding driver can easily manage the recovery unit without being adversely affected by the foliage conveying device, and the foliage conveying device can be arranged so as not to interfere with 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 the traveling.

According to the structure of the second aspect of the present invention, the leaf-cutting device and the foliage-portion conveying device also use a single endless rotation band for carrying the foliage-portion, and the leaf-cutting device serves as a harvesting conveyance device. To arrange the foliage part conveying device in a state of conveying the cutting foliage part diagonally across the front part of the machine on the other side of the machine side on the other side, two wheels of the front and rear of the leaf cutting device, and a conveying device for harvesting Since the endless rotation band is wound in a triangular state on a single ring placed on the front side of the machine on the other side of the machine on the opposite side, it is used as an endless rotation band for carrying the foliage of the leaf cutting device. The number of wheels and the number of endless rotation bands can be reduced as compared with the case where the endless rotation bands for squeezing and holding the foliage of the foliage transfer device are separately provided, thereby simplifying the transfer configuration.

[0008]

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 recovery section by the boarding driver is easy and the operation is easy. Root crop harvesters are now available. In particular, according to the second aspect of the present invention, it is possible to provide a root vegetable harvesting machine that can achieve cost reduction by simplifying the transport configuration and that is also economically superior.
