Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a root vegetable harvesting machine for digging root vegetables such as radish.

[0002]

2. Description of the Related Art Conventionally, root vegetables have been extracted upward by a pulling transporter pulled by a tractor and harvested.

[0003]

In the above-mentioned prior art, since the extracted root vegetables are released to the surface of the field, it is necessary to collect the root vegetables after the root vegetables extraction work, which facilitates labor saving and work efficiency improvement. There was a problem that I could not plan.

[0004]

SUMMARY OF THE INVENTION Therefore, according to the present invention, in a root vegetable harvesting machine for continuously extracting root vegetables by providing a withdrawing carrier for extracting and conveying root vegetables, a lateral feeding conveyor for conveying root vegetables in the left and right direction is withdrawn. In addition to being provided on the feed end side of the carrier, a container for containing root vegetables is arranged in front of the horizontal feed conveyor, and the conveyor is mounted so as to be rotatable in the horizontal direction around the rotation fulcrum shaft at one end of the horizontal feed conveyor. Even if the amount of root vegetables in the container increases, backward movement of the body weight can be prevented by providing a container in front of the horizontal conveyor, and it is possible to easily increase the size of the container and simplify the collection of root vegetables. At the same time, the rear of the container can be opened by horizontal rotation of the horizontal feed conveyor, and the work of loading and unloading the container from the rear can be easily performed.

Further, in a root vegetable harvesting machine for continuously extracting root vegetables by providing a pulling carrier for pulling and carrying root vegetables, a lateral feed conveyor for feeding root vegetables in the left-right direction is provided at the feed end side of the pulling carrier. A container in which the root vegetables are placed is arranged in front of the horizontal feed conveyor, and the horizontal feed conveyor is attached to the feed end of the pulling transfer body so that the position can be adjusted in the left-right direction. The root vegetable transfer position on the side of the end of the horizontal conveyor can be easily changed with respect to the container and the like.

Further, in a root vegetable harvesting machine for continuously extracting root vegetables by providing a pulling carrier for pulling and carrying root vegetables, a lateral feeding conveyor for laterally feeding root vegetables is provided at the feed end side of the pulling carrier. A container for storing root vegetables is arranged on the front side of the transverse conveyor, and the container is slidably mounted in the front-rear direction via guide rails.For example, when collecting root vegetables, the container is placed in the front to move the center of gravity. In addition to being able to prevent it, the container can be moved rearward to facilitate the loading / unloading work from the rear.
