Testing device for mechanical properties and forced vibration characteristics of crop leaves

The invention provides a device for testing mechanical properties and forced vibration characteristics of crop leaves, which comprises a loading bottom plate, a whole worktable is divided into two parts by a loading frame on the loading bottom plate, and the rotation of ball screws on two sides of the loading frame is controlled by a servo motor below the loading frame, so that a sliding arm on the right half part of the worktable moves up and down; a converter is arranged at the tail end of the sliding arm and connected with an upper clamping head, a pressing piece and a pressing head, a lower clamping head, a pressing piece table and a twisting table are installed on a rotating disc below the converter, and the stretching, bending and twisting performance of the blade is tested. The left half part of the test bed is provided with a split type injector through a ball screw, a rotatable storage table is arranged below the split type injector, a blade clamping device for fixing blades, a blade handle clamping
