Efficient electromechanical equipment

The invention relates to efficient electromechanical equipment. The efficient electromechanical equipment comprises a fixing box, a supporting rod, a transverse rod, a driving mechanism and a limitingmechanism, the driving mechanism comprises a motor, a driving rod and a screening barrel, and the limiting mechanism comprises a limiting assembly and a positioning assembly. According to the efficient electromechanical equipment, screening of sand and stones is achieved through cooperation of the fixing mechanism and the limiting mechanism, the sand and stones located in a screening barrel are thrown out through centrifugal force, the screened sand and stones are located outside the screening barrel and then flow out through a discharging port, the effect that screening can be carried out onthe sand and stones with different requirements is achieved through the detachable screening barrel, limiting of the screening barrel is achieved through the limiting mechanism, and meanwhile, limiting of the screening barrel
