The treading stress load device of the mat plant which covers the soil surface

摘要

Topic As in the form which is close to actually treading stress load, quantitative, at the same time many test Ku can be treated efficiently the treading stress load device of the mat plant which covers soil surface such as simple lawn is offered.SolutionsAround the standards which are provided in substantial verticality direction the longitudinal direction abbreviating crossing in the supporter 2 who possesses the revolving shaft 5 which, turns and revolving shaft 5 in the arm concatenating 7 which it is locked is supported and arm 7, the Drive axis 9 which is provided in parallel and Drive axis 9 it turns just, convolutes on the mat plant of the soil surface and in the wheel it concatenates 11 which makes treading stress and arm 7, the computer section it is the treading stress load device where consists of with power supply section 3 to motor 13 of 1 which possesses the motor 13 which synchronization is done and computer section 1 in AC power supply frequency. To apply the treading stress load which it can make fixed, is close to actual usage condition it is possible the travel speed of wheel 11 with the motor 13 of the fixed revolution type which synchronization is done in AC power supply frequency. And, while stationary treading stress condition is maintained, it becomes possible to apply treading stress load into many test Ku at one time. Choice figure Drawing 1
