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:...
Facilitative glucose transport is mediated by one or more of the members of the closely related glucose transporter (GLUT) family. Thirteen members of the GLUT family have been described thus far. GLUT1 is a widely expressed isoform that provides many cells with their basic glucose requirement. It is also the primary transporter across the blood-brain barrier. This review describes the distribution...
