Solution Overview
Problem
Tree planting in vast, rough land with existing mechanization technologies faces inefficiencies due to differences in vehicle posture during soil cultivation and planting, leading to potential rework and reduced efficiency, especially when dealing with uneven terrain and obstacles like stumps and rocks.
Innovation Solution
A tree planting system comprising a cultivating machine and a planting machine, equipped with position detecting devices and a management device, which allows for accurate tracking and alignment of cultivated soil lines and planting positions, ensuring precise planting along cultivated lines and improving efficiency by minimizing deviations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If one vehicle performs both cultivation work and planting work, then device complexity is reduced, but manufacturing precision deteriorates due to vehicle posture differences on rough terrain
Solution Approach 1:
The system divides the work into two separate vehicles: a first vehicle for cultivation work and a second vehicle for planting work. This segmentation allows each vehicle to be optimized for its specific function, with the planting vehicle able to precisely follow the cultivated track without being affected by cultivation equipment that would interfere with planting precision.
Solution Approach 2:
The patent introduces an information management device that acts as an intermediary between the two vehicles. It receives track information from the first vehicle and transmits it to the second vehicle, enabling the planting vehicle to accurately follow the cultivated track through GPS guidance, thus resolving the precision issue while maintaining system separation.
2Productivity
If one vehicle performs both cultivation work and planting work, then productivity is improved by reducing equipment setup time, but reliability deteriorates due to inability to complete planting in all cultivated portions
Solution Approach 1:
The system implements feedback through the information management device that continuously monitors the cultivated track and guides the planting vehicle. This feedback mechanism ensures that the planting vehicle can reliably complete planting in all cultivated portions by accurately following the recorded track, even on rough terrain where vehicle posture varies.
3Adaptability or versatility
If cultivation and planting are performed in a spot rather than in a line, then adaptability to rough terrain is improved, but productivity deteriorates in extremely vast land
Solution Approach 1:
The patent replaces mechanical coupling between cultivation and planting operations with an information-based guidance system. The planting vehicle uses GPS and track information to follow the cultivated line without mechanical connection to the cultivation vehicle, combining the benefits of independent spot operations with the efficiency of continuous line-following work in vast areas.

AI summary
A first machine of a tree planting system includes: a cultivator cultivating soil where a plant for tree planting is to be planted; a first traveling device traveling with the cultivator; and a cultivated position detector obtaining and outputting actual cultivated positions corresponding to positions of the cultivator while the cultivator travels with the first traveling device and cultivates the soil. A management device of the tree planting system stores actual cultivated positions. A second machine of the tree planting system includes: a planting device planting a plant in the soil; a second traveling device traveling with the planting device; a planting device position detector obtaining a position of the planting device; and a controller controlling a position of the planting device based on: actual cultivated positions acquired from the management device; and the position of the planting device at the timing when a plant is planted.
