Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vegetable harvesting / transporting apparatus for use in, for example, heading vegetable harvesting for harvesting cabbage, lettuce, Chinese cabbage and the like.

[0002]

2. Description of the Related Art Conventionally, head vegetables such as cabbage, lettuce, Chinese cabbage and the like have been manually harvested by an operator while judging the hardness of a leaf ball.

[0003]

[Problems to be Solved by the Invention] In the conventional harvesting work, the transport of the leaves was mechanized by using a transport cart,
Since the work of cutting the stems and loading the leaf balls on the trolley is dependent on human power, there is a problem that it is not easy to reduce labor and improve work efficiency. Therefore, if a vegetable harvesting machine that automatically collects vegetables from the field is developed, labor for collecting vegetables from the field can be saved, but it is necessary to perform cumbersome work to transfer the vegetables from the harvester to a truck bed. There were some problems.

[0004]

According to the present invention, a vegetable harvesting / transporting device includes a vegetable sensor for detecting a vegetable harvester and an automatic steering means for automatically following the vegetable harvester. And a remote guiding means for running the container carrier by remote control of an operator, and configured to move the container carrier based on an output of the above-mentioned sensor or the remote guiding means. By the automatic follow-up operation of the container carrier,
The operation of loading the vegetables of the harvester into the container truck can be easily performed, and by remote control of the container truck,
It is possible to move the container truck full of vegetables to the collection place while continuing the vegetable collection of the harvester, thereby easily shortening the time and labor of the vegetable harvesting operation.
