Description

Concrete aggregate screening machine Technical Field The utility model relates to the technical field of concrete production, in particular to a concrete aggregate screening machine. Background The concrete is a general term of engineering composite materials which are formed by cementing aggregate into a whole by cementing materials, the term of concrete is generally used for cementing materials, sand and stone are used as aggregate, and the cement concrete which is obtained by mixing the cement concrete and water (which can contain additives and admixture) according to a certain proportion and stirring, is also called ordinary concrete, and is widely applied to civil engineering. The concrete is producing, carries out screening treatment to the aggregate through the screening machine, and current screening machine is mostly vibration screening, and screening net is inconvenient for change when screening inefficiency, can't adapt to the screening demand of different aperture aggregates, consequently, we propose concrete aggregate screening machine and solve this prior art defect. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a concrete aggregate screening machine. The concrete aggregate screening machine comprises a base, wherein a driving motor is arranged at the front end of the base, a loading seat connected with the base is arranged at the output end of the driving motor, an output motor is arranged at the lower end of the loading seat, a cylinder seat positioned above the loading seat is arranged at the output shaft of the output motor, a plurality of slots are arranged at the upper end of the cylinder seat, a screen plate is inserted into the slots, a plurality of screen holes are arranged on the screen plate, a protective cover positioned outside the cylinder seat is arranged on the loading seat, and a sealing cover locking assembly for sealing the opening of the cylinder seat and limiting and locking the screen plate is arranged on the protective cover; The surface bottom of the protective cover is provided with a discharge hole, and the base is provided with a receiving seat. By adopting the technical scheme, aggregate is stored through the arranged cylinder seat, the opening of the cylinder seat is covered by matching with the sealing cover locking component, and the sieve plate is locked into the slot fixed in the cylinder seat, so that the sieve plates with different apertures can be conveniently replaced according to the requirement of aggregate screening, and the replacement efficiency of installation is improved; after the opening of the cylinder seat is sealed, the rotation of the cylinder seat is driven through the work of the output motor, the rolling of the stored aggregate can be accelerated, the aggregate is screened out from the aperture of the screen plate, the aggregate is stored through the shielding cover, and is discharged from the discharge port, the rest large-particle aggregate is stored in the cylinder seat, the deflection of the cylinder seat on the loading seat is driven by the driving motor, the aggregate in the cylinder seat can be dumped and stored in the receiving seat, and the screening effect and efficiency are improved. As a preferable technical scheme of the utility model, the sealing cover locking component comprises a supporting seat arranged at the upper end of the protective cover, a hydraulic push rod is arranged at the upper end of the supporting seat, a rotating seat is arranged at the push rod of the hydraulic push rod, and a cover plate for sealing the sealing cover is arranged at the concentric center of the lower end of the rotating seat. As a preferable technical scheme of the utility model, a plurality of locking blocks which are respectively positioned in the slots and used for limiting the sieve plate are arranged outside the cover plate.
