Description

ROBOT SYSTEM FOR MOVING AN AGRICULTURAL MACHINE}

The present invention relates to a conveying system of agricultural machinery for agricultural work, and more particularly to a ROBOT SYSTEM FOR MOVING AN AGRICULTURAL MACHINE to help facilitate agricultural work using agricultural machinery on a crop bed.

Although agriculture is the oldest industry, the working environment is still very poor. Since crops are most prosperous in the most difficult heat to work, conventional methods that have relied on human labor are not suitable for modern working environments. Although much progress has recently been made in the mechanization of agricultural work, the mechanization during the growing season is very poor. Existing farming machines such as tractors and combines, which are considered as representative farming machines, are used for sowing or harvesting without fear of damaging crops. However, although the work performed on crop beds such as cultivating crops, fertilizing, spraying pesticides, weeding, and harvesting fruit during the growing season of the crops is often necessary for a long time, suitable agricultural machines have not been developed. The reason for this is that during the growing season of the crop, it is easy to fall down because the agricultural machinery has to stay only in the narrow valleys between the crop beds, and the crops have to be observed from the side, which makes accurate and smooth farming difficult. In particular, when harvesting a crop that weighs like watermelon, there is a problem that it is unstable to use agricultural machinery because of the load of the crop.

In addition, because the width of the bones, length, height, etc. of the bones existing between the crop beds are various, the agricultural machinery cannot be easily used, and there is a problem that a large space is required to move the agricultural machinery to another adjacent crop bed.

In order to achieve the above object, the agricultural machinery transport robot system according to the present invention, the first robot installed on one side of the crop bed; A second robot installed on the other side of the crop bed while communicating with the first robot by wire or / and wirelessly; And it is configured to include a link connecting the first robot and the second robot, and a farm machine for agricultural work.

Here, the present invention preferably further includes a traveling line for guiding the movement of the first robot and the second robot.

The first robot and the second robot are preferably connected to the link and the rotary joint. Here, the rotary joint is rotatable in the horizontal and vertical direction, and can be extended or contracted in the longitudinal direction of the link.

On the other hand, when the agricultural machinery transport robot system according to the present invention to move to another crop bed while moving along the traveling line, the agricultural machinery transport robot system reaches a certain position and the robot of any one of the first robot and the second robot It can rotate around this other robot and move to another crop bed.

Such a farm machinery transport robot system according to the present invention, there is an effect that can work on farms without damaging the crops.

In addition, the present invention can be easily and stably farming work in the valley between the crop bed, the height, length, width, etc. are not constant, and furthermore, there is an effect that can move the farm machinery to another crop bed in a narrow space.

In addition, the present invention, by providing a method that can easily and stably move the farm machinery in any environment, there is an effect that can promote the emergence of intelligent farm machinery dedicated to farm work.
