According to the device, a
conveyor belt is arranged on a
machine body in a penetrating mode, a partition plate is arranged on the upper surface of the
conveyor belt, a
vibration motor is arranged on the left side of the
machine body, the output end of the
vibration motor is fixedly connected with a flow guide frame, the flow guide frame is located above the partition plate, and an electric telescopic rod is fixedly connected into the
machine body. An electric telescopic rod is arranged on the machine body, a C-shaped plate is fixedly connected to the output end of the electric telescopic rod, a
sponge block is arranged on the lower surface of the C-shaped plate, a cleaning
assembly and a screening
assembly are arranged on the machine body, and two robots are arranged in the machine body and located on the two sides of the conveying belt correspondingly. The
sedum aizoon is cleaned to remove soil and then screened, so that the appearance is clearer, screening is facilitated, improvement of subsequent
seedling raising and
transplanting uniformity is facilitated, meanwhile, the
sedum aizoon can be limited, and displacement during cleaning is avoided.
