Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Conventionally, in a self-propelled root vegetable harvesting machine having a pair of right and left crawlers, a container for storing excavated root vegetables is placed at the end of the vehicle so that the container can be transshipped from the rear of the vehicle. The root crops that enter the soil and are planted in the soil are dug in the left front of the fuselage on the opposite side of the operation control unit on the right front of the fuselage, and are pulled diagonally upward on the left side of the fuselage by the pull-out carrier. Transported from the left side to the right side of the body above the front part of the container by the second carrier, conveyed rearward on the right side of the body by the third carrier, and put into the container from the conveyance end of the third carrier. . In addition, the foliage is cut at the transfer end portion of the second transfer body.

[0003]

In the conventional self-propelled root vegetable harvester, since the container with large weight fluctuation is located at the rear end of the body, the center of gravity of the body is shifted between when the container is empty and when the container is full. Large, which has an adverse effect on harvesting travel. In some cases, root crops may make a U-turn at the edge of the field and move on to the next adjacent harvest. In other words, to harvest only from one side, lowering the container backwards will be an obstacle to retreat when the container moves to the adjacent harvesting, and lowering the container backwards will remove the container with a forklift etc. When carrying out, it is not easy to insert a forklift fork into a container. In addition, since root vegetables are excavated on the side opposite to the operation section, the alignment cannot be easily performed. In addition, there is a transport route for root vegetables dug above the container,
Foreign matter such as foliage enters the container. In addition, because the transportation route of excavated root vegetables is long and there are two inheritances,
Root vegetables are often damaged. And so on.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention relates to a self-propelled root vegetable harvesting machine, which pulls and conveys roots and leaves of root vegetables that penetrate into the soil and are planted, and pull it upward and diagonally rearward. The body extends from the front to the rear on one side of the fuselage, and a container for storing excavated root vegetables is mounted at the approximate center of the aircraft, and the container with large weight fluctuation is located at the approximate center of the aircraft. Therefore, the movement of the center of gravity of the airframe is small between when the container is empty and when the container is full, and it is possible to prevent the harvest traveling from being adversely affected.

[0005] In a self-propelled root vegetable harvester, a pulling and conveying body that sandwiches the foliage of root vegetables that enter the soil and is planted and lifts obliquely upward and rearward is provided on one side of the fuselage.

When moving to the adjacent harvest, the container can be retracted right behind without obstruction, so that the container can be immediately moved to the adjacent harvest and the forklift fork can be easily inserted into the container.

In a self-propelled root vegetable harvesting machine, a pulling and conveying body which sandwiches the foliage of root vegetables which enter the soil and is planted and which is pulled obliquely upward and rearward is operated on one side of the front part of the body. It extends from one side of the operation unit to the rear part of the fuselage, and excavates root crops right beside or diagonally behind the operation operation unit, so that alignment can be easily performed.

[0007] In a self-propelled root vegetable harvester, a pulling and conveying body that sandwiches the foliage of root vegetables that penetrate into the soil and is planted and lifts obliquely upward and rearward is provided on one side of the body. A container that extends from the section to the back and stores the excavated root vegetables,
A horizontal transport body mounted at approximately the center of the fuselage and transporting root crops dug toward one side of the fuselage opposite to the pull-out transport body with the transport start end positioned below the clamping end of the pull-out transport body. To
The container is mounted on the rear part of the fuselage behind the container, and while the container is mounted approximately in the center of the fuselage, there is no transport route for root crops dug above the container. Can be eliminated, the transport route of the excavated root vegetables can be shortened, and the inheritance can be performed at only one place, so that damage to the root vegetables can be reduced.

Further, in a self-propelled root vegetable harvester, a pull-out carrier body that sandwiches the foliage of root vegetables that penetrates into the soil and is planted and pulls up diagonally rearward is provided on one side of the body. A container that extends from the section to the back and stores the excavated root vegetables,
A horizontal transport body mounted at approximately the center of the fuselage and transporting root crops dug toward one side of the fuselage opposite to the pull-out transport body with the transport start end positioned below the clamping end of the pull-out transport body. To
A work space having a worker step at the bottom is formed between the container and the horizontal transport body, and the container is mounted at a substantially central portion of the fuselage. In a space, several workers can efficiently perform root cutting work and loading work in containers.

Further, in a self-propelled root vegetable harvesting machine, a pulling and conveying body which sandwiches the foliage of root vegetables which penetrates into the soil and is planted and lifts obliquely upward and rearward is provided on one side of the body. A container that extends from the section to the back and stores the excavated root vegetables,
A horizontal transport body mounted at approximately the center of the fuselage and transporting root crops dug toward one side of the fuselage opposite to the pull-out transport body with the transport start end positioned below the clamping end of the pull-out transport body. To
A cutting section is provided horizontally behind the container behind the container to cut the foliage of root crops dug during the transfer of the horizontal transport body, and a step for an operator is provided between the container and the horizontal transport body. It forms a work space at the bottom, and the cut foliage of the excavated root vegetables is dropped and discharged to the harvested field behind the fuselage, so that post-processing of the cut foliage can be unnecessary. .
