Gravel sorting device for engineering machinery

Abstract

The invention discloses a gravel sorting device for engineering machinery. The device comprises a rack, a rotary screen, a cleaning device and a winding pulley. The rotary screen is obliquely mountedon the rack, and the rack is provided with a motor and a feeding port at the two ends of the rotary screen respectively, wherein the motor is connected with the rotary screen through a rotating shaft,and the feeding port extends into the rotary screen; a sand outlet and a stone outlet are formed below the rotary screen; the section of the cleaning device is in an arc shape, and the bottom of thecleaning device is in sliding connection with the rack; a water conveying connector and a gas conveying connector are arranged at the outer side of the cleaning device, a water conveying channel and agas conveying channel are formed in the cleaning device, the winding pulley is installed on the rack, and a traction rope is wound on the winding pulley and connected with the cleaning device. The rotary screen of a gravel separator can be cleaned and subjected to soot blowing, so the meshes of the rotary screen can be effectively prevented from being blocked; the cleaning capacity is high, the efficiency is high, and the device has the air drying function.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a sand and gravel sorting device for engineering machinery. Background technique [0002] In the field of mechanical engineering, sand and gravel are often used, so the separation of sand and gravel has become an indispensable work in mechanical engineering. At present, drum screen sand and gravel separators are often used in engineering to separate sand and gravel from mixed raw materials. However, when the current sand and gravel separator is in use, the mesh of the drum screen is often blocked by sand and dust after a long time of use, and the sieving function is lost. Workers need to spend a lot of time and energy cleaning the mesh of the drum screen to recover. This not only increases the workload of workers, but also easily delays the progress of the project and affects the efficiency of the project.
