Description

Mixing soil aggregate screening device Technical Field The utility model relates to the technical field of screening devices, in particular to a mixed soil aggregate screening device. Background The concrete aggregate is divided into coarse aggregate and fine aggregate, wherein the coarse aggregate is pebble, broken stone and the like, the fine aggregate is natural sand, artificial sand and the like, the aggregate with the particle size of less than 4.75mm is called fine aggregate commonly called sand, the fine aggregate is required to be screened by a screening device before being used, and the particle impurities with larger particle size are removed, but when the screening device is used at present, some particle impurities with larger particle size are easy to block in the sieve holes of the screening device, so that the screening efficiency of the screening device is reduced, and then workers are required to manually clean the screening device, and the labor burden of the workers is increased. Disclosure of utility model The utility model discloses a mixed soil aggregate screening device, which solves the problem that granular impurities with larger grain diameters are easy to block in sieve holes of the screening device, and subsequently, manual cleaning by staff is required. In order to solve the technical problems, the utility model adopts the following technical scheme: A mixed soil aggregate screening device comprises a box body, a rotatable screening cylinder is arranged in the box body, a motor used for driving the screening cylinder is arranged in the box body, a feeding pipe penetrating through the axis of one side of the screening cylinder is arranged on the box body, openings are formed in the top and the bottom of the screening cylinder, sealing rods capable of moving out of the openings are arranged in the openings, connecting rods are fixed between the two sealing rods, connecting plates fixed in the screening cylinder are arranged on two sides of the sealing rods, springs are fixed between the connecting plates and the sealing rods, a lifting plate is arranged above the screening cylinder, an inserting rod capable of being inserted into an opening in the screening cylinder is fixed at the bottom of the lifting plate, and an electric telescopic rod used for driving the lifting plate is arranged on the box body.
