Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art A harvesting transporting device for holding the foliage of root vegetables such as carrots and radishes planted in the field, pulling them diagonally upward at the rear of the machine and suspending them is provided on one side of the machine for harvesting. A root crop harvester equipped with a leaf-cutting device that cuts the foliage of root vegetables from the transport device, and a collection unit that collects root vegetables from the leaf-cutting device at the rear of the machine behind the transport device for harvesting The applicant proposed earlier. In this proposed structure, the harvested root vegetables are stored in the container placed on the fixed table at the rear corner of the machine, and when the container is replaced with the fixed table, the previously placed container is artificially moved. After removing it, another container was artificially placed on the fixed table.

[0003]

However, it is difficult to carry a heavy container from the fixed base when the container is full of harvested root vegetables, and when the container is replaced, it is possible that there is no container on the fixed base. The root vegetables from the conveyor easily spilled onto the fixed table, leaving room for improvement in terms of container handling and recovery functions. An object of the present invention is to make it possible to easily take a container in and out of a root vegetable receiving position of a collection unit and to perform it without spilling a vegetable from the conveyor.

[0004]

A feature 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 aircraft, and hangs and transports it. A root cutting device that is provided on the rear side of the harvesting transport device and that has a collection unit that cuts the foliage of the root vegetables from the harvesting transport device and that collects the root vegetables from the leaf cutting device. In the harvesting machine, a conveyor for supplying root vegetables from the leaf-cutting device to the container at the root-corner receiving position in the rear corner of the machine is provided in the recovery unit, and a container storage space is provided below the rear of the conveyor. The container is formed in a state in which the container can be received in the container receiving position by moving the container forward and the container can be taken out from the container accommodation space in the lateral direction of the machine.

[0005]

[Function] In other words, when the container at the root vegetable receiving position is full of harvested root vegetables, it is sufficient to move the container forward while moving it to the container storage space below the rear part of the conveyor. Easy to move without having to carry a heavy container full of harvested root vegetables. Also, when moving a container full of harvested root vegetables forward, you can set an empty container at the root vegetable receiving position in a state of being connected to the rear of the container, making it easy to replenish the container and remove it from the conveyor. Can be run without spilling root vegetables.

[0006]

As a result, not only the processing of root vegetables after harvesting is facilitated by cutting the foliage, but also the container in the recovery section can be easily replaced, and the root vegetables from the conveyor are not spilled during the replacement. We can now provide an excellent root vegetable harvester.

And soil cutting blade 4 are provided, and the foliage of root vegetables is weeded 3
And the soil on both sides of the root vegetables is cut by the soil cutting blades 4 so that the root vegetables can be smoothly pulled out. In the harvesting transport device 1, as shown in FIG. 3, a guide roller 1b that presses the left and right holding and transporting belts 1a in the approaching direction is provided.
The holder 1e is slidably attached to the frame 1c while being urged by a spring 1d, and is configured to hold the foliage portion strongly at the conveyance start end side and weakly at the conveyance end side. A leaf cutting device 8 for cutting the foliage of the root vegetables from the harvesting transport device 1 is provided behind the harvesting transport device 1 to form the leaf cutting device 8, and the root vegetables suspended by the harvesting transport device 1 are formed. Positionable conveying device 8a that acts on the upper end of a class, and a pair of left and right drivable sandwiching conveying belts that receive the foliage from the positioning conveyer device 8a in a fixed position above the holding position. And a pair of left and right rotatable blades 8c for driving and rotatably cutting roots and roots of root vegetables conveyed by the cutting conveyance device 8b. In the positioning device 8a, as shown in FIG. 3, the rollers 8ac are attached to the holders 8ab attached to the left and right rotating chains 8aa in a state in which the rollers 8ac are biased in the approaching direction by the springs 8ad.
The axis of the ac shaft is set so as to rotate by the movement of the foliage in the longitudinal direction, and the root vegetables are configured to rise until they come into contact with the roller 8ac when the harvesting transport device 1 pulls the root vegetables. An electric fan 5 is provided to clean the head and the like of the roller and the roller 8ac by blowing air to prevent the roller 8ac from rotating improperly and to improve the durability of the rotary blade 8c. A collecting section 9 for collecting root vegetables from the leaf-cutting device 8 is provided below the leaf-cutting and conveying apparatus 8 at the rear of the harvesting conveying apparatus 1 to form the collecting section 9 so that a root vegetable having a small diameter is downward.
