Efficient sand screening device for construction

Abstract

The invention discloses an efficient sand screening device for construction. The efficient sand screening device for construction comprises a main device body, a feed port, a vertical rod, a transverse plate, a motor, a damping device, a discharge port and a storage battery, wherein the feed port is positioned at the top of the main device body, and the lower side of the vertical rod is movably connected with a sloping plate; the inner wall of the transverse plate is connected with a bolt in a penetrating mode, and a nut is movably arranged on the right side of the transverse plate; sand leakage holes penetrate through the inner walls of the transverse plate and the sloping plate, and the sloping plate is connected with the transverse plate through a rotating pin; the left side of the motor is movably connected with a connecting rod, and a middle plate is fixedly arranged on the lower side of the motor; and a vibrator is fixedly arranged on the right side of the middle plate. The efficient sand screening device for construction is provided with the nut, and the bolt is taken out by unscrewing the nut, so that the transverse plate is separated from the sloping plate on the left side, and coarse sand on the transverse plate is discharged from the discharge port. Thus, during sand screening next time, the efficiency of sand screening can be improved, and the coarse sand is prevented from blocking the sand leakage holes. The sand screening device has high practicality, is suitable for use and production and has good development prospects.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to an efficient sand screening device for construction. Background technique [0002] The sand screening device for construction is a device used for filtering sand during construction. It adopts a flat roller screen drum, and ensures that the material flow can be continuously rolled for more than five circles between the multi-turn inner spiral blades in the screen drum, so that the sand The material is fully dispersed and separated by repeated rolling and sliding; it is different from the pushing and burying of large and small materials caused by the inclined roller sieve, and the screening process is rushed; it is also different from the vibration and mixing of large and small materials caused by the inclined vibrating screen. [0003] However, the existing high-efficiency sand screening devices for construction have low sand screening efficiency. After a period of...
