Abstract

The invention relates to a screening device and particularly relates to a sand screening device applied to road and bridge construction. The sand screening device can realize multi-stage screening andseparated discharging and can also limit the flow rate of sand which enters the device. A clamping block III on a screening device III is in interference fit with a clamping groove I; a clamping block IV on the screening device III is connected to the lower end of a sliding plate II; the screening device III is positioned above a screening device II; a supporting plate is positioned above a flowchannel; a side baffle is fixedly connected to the side surface of a screening device I in a welding way; a bracket is fixedly connected to the lower end of a screening box in a welding way; one end of a fixed rod is fixedly connected to the side surface of the screening box in a welding way; a motor bracket is fixedly connected to the other end of the fixed rod in a welding way; a motor is fixedly connected to the motor bracket through a bolt; a rotating shaft is arranged on the motor; a rotary disc is fixedly connected to the rotating shaft through a key; one end of a transmission rod is movably connected to an eccentric position of the rotary disc; and the other end of a rotating rod is movably connected to a sliding plate II via a through hole II.

Description

technical field [0001] The invention relates to a screening device, in particular to a sand screening device for road and bridge construction. Background technique [0002] In the process of construction on the construction site, it is necessary to mix a variable amount of sand into the lime, and when the sand is transported to the construction site, the particles are often uneven, and some sand particles are relatively large, which is not suitable for mixing into the lime, so workers need to pass through the sieve. The net sifts the sand. However, the current screening operation is relatively laborious and the screening tools are relatively simple, resulting in a waste of manpower, so this sand screening device is designed. Contents of the invention [0003] The invention provides a sand screening device for road and bridge construction. The beneficial effect is that it can not only carry out multi-stage screening and discharge materials separately, but also can limit th...
