In order to save time of digging hole when trees are planted, a robot that has six degrees of freedom is developed. In this paper the structure and function of a forestation hole digging robot is introduced and analyzed. At the same time, by the experiment it can be proved that the efficiency of the robot is very high and the ground surface destroyed by the robot is very small. The maximum diameter...
The logging harvester is made up of a walking mechanism, a mechanical arm, a felling head and a driving control system, which can do the works of felling, limbing, measuring and bucking. Because the ground surface of the forest land is very rough, the vibration should be studied when it is going in the forest land in order to prevent the harmful effects to the machine and driver. In this paper, the...
With the mature stage of the fast-growing plantation in China, the traditional working procedure can not meet with the need of the large-scale clear-cutting. So, a logging harvester which can be operated by hand or automation is developed. The ZL-50 wheeled loader is adopted as its walking mechanism and a manipulator with 9 degrees of freedom, a three-dimensional laser-scanner and a RBF neural network...
In order to improve the efficiency of felling trees and ensure the safety of felling worker, a robot which can fell and bunch is developed. This robot adopts SDWY-60 caterpillar excavator as a walking mechanism and equips a manipulator with 6 degrees of freedom and a RBF neural network controller, which can be operated by hand or automation. The main technical parameters of the robot are as follows:...
