Manipulator of soil sample preparation equipment

The utility model discloses a manipulator of soil sample preparation equipment, which relates to the field of soil sample preparation equipment and comprises an X-axis linear rail and the like, an X-axis carriage is driven by an X-axis motor and freely moves along the length direction of the X-axis linear rail; the Y-axis carriage is driven by a Y-axis motor and freely moves in the length direction of the Y-axis linear rail; the clamping jaw mechanism is driven by a Z-axis motor and moves up and down in the length direction of a Z-axis lead screw, and driving control over the clamping jaw mechanism in the X direction, the Y direction and the Z direction is achieved. The electric clamping jaw drives the clamping fingers to rotate to achieve universal clamping according to different soil containers. The clamping and rotating device has a clamping function and a rotating function and is small in size; a pure electric structure is adopted, and the clamping efficiency is high; the device can adapt to clamping of s
