Novel rolling type sand sieving machine

Abstract

The invention discloses a novel rolling type sand sieving machine. The novel rolling type sand sieving machine comprises a rolling type sand sieving machine body, an external rolling sand filtering net and a coarse material outlet, wherein a fixing table is arranged on the rolling type sand sieving machine body; the external rolling sand filtering net is rotatably arranged between two support frames; a gear ring is arranged on the exterior of one end of the external rolling sand filtering net in a sleeving manner; the bottom of the gear ring is in transmission connection with a driving motor fixedly connected to the fixing table through a small gear; and the other end of the external rolling sand filtering net is located on the fixing table and is provided with the coarse material outlet convenient for discharging. The external rolling sand filtering net is arranged on the sand sieving machine; an internal rolling sand filtering net is rotatably arranged inside the external rolling sand filtering net in a sleeving manner and can be rotated by loosening a spiral fastening clamp; the radius of produced sand can be adjusted through the mutual rotation between the internal rolling sandfiltering net and the external rolling sand filtering net; and due to the structure, the novel rolling type sand sieving machine can achieve the purpose of sieving sand with different particle radiuses , and is simple in structure and has strong practicability.

Description

technical field [0001] The present invention relates to the technical field of construction equipment, in particular to a novel rolling sand screening machine. Background technique [0002] During use, the trommel sand screening machine runs slowly and evenly, with little impact and vibration, stable operation, and simple installation. It can be placed directly on the flat ground or floor or under the silo. [0003] Drum sand screening machine is a very common construction equipment in construction engineering. It is usually used for screening sand materials so as to achieve the purpose of qualified sand and gravel fine materials. However, existing drum sand screening machines can only screen certain materials. A fine sand and gravel material with a small particle radius is not practical and cannot meet the diverse production needs. Secondly, in the process of sand screening, there are often some agglomerated sand materials, which are very difficult to pass through the scree...
