A gravel screening device for construction

Abstract

The invention provides a gravel screening device for buildings. The device comprises a shell, a plurality of screen nets, a plurality of vibrating mechanisms, a stirring mechanism and a driving mechanism, wherein the screens are obliquely disposed in the shell in parallel in sequence from top to bottom; each pair of vibrating mechanisms is arranged between every two adjacent screen nets; cams of the vibrating mechanisms drive a pair of floating blocks of the vibrating mechanisms to move so as to make the floating blocks impact on the corresponding screen nets; the stirring mechanism comprisesa plurality of stirring plates and a pulling rope; the stirring plates are slideably disposed on guiding columns of a cavity; the stirring plates are perpendicular to the screen nets; the pulling ropeconnect all the stirring plates in sequence together; and the driving mechanism comprises a motor, a first transmission mechanism and a second transmission mechanism, wherein the motor drives all thevibrating mechanisms to work together through the first transmission mechanism, and meanwhile the motor drives all the stirring plates to reciprocate together through the second transmission mechanism. The gravel screening device for buildings can achieve uniform vibration and is high in working efficiency and good in screening effect.

Description

technical field [0001] The invention relates to a screening device, in particular to a construction gravel screening device. Background technique [0002] At present, in many sand fields, the sand fished out of the river is directly loaded and unloaded and sold with a forklift. Before the sale, the river sand is basically not classified and screened. After being transported to the construction site, secondary treatment is required. Sand and gravel screening The machine is a machine that classifies sand and gravel according to different particle sizes. The sand and gravel of different sizes after screening are applied to suitable occasions. The existing sand and gravel screening machines usually use vibration motors to speed up the screening during use. For volume comparison A large screening machine needs multiple vibrating motors or a vibrating motor with relatively large power. The noise is large during the production process, and the vibration effect is poor at places far...
