A sorting sand screening machine

Abstract

The invention relates to a sand screen, in particular to a classifying sand screen. The classifying sand screen comprises a base body, a first screen mesh, an initial collecting hopper, an oscillating part, a slow falling mechanism, a braking part, a transmission part, a dividing hopper, a shifter and a rack, wherein single-layer sand stone is conveyed to the first screen mesh through buffering and dividing the added sand stone through the initial collecting hopper in combination with vibration, so that the noise is lowered, the service life of the first screen mesh is prolonged, and the screening efficiency is increased; through the alternate lifting of two baffle plates, the single-layer sand stone is blocked in sections, the screening time is prolonged, the length of the first screen mesh is reduced, and the screening efficiency can also be increased; an arc frame and an second screen mesh swinging back and forth obliquely can increase the stroke of sand screening movement, the length of the second screen mesh is reduced, and the screening efficiency of coarse sand and fine sand can be improved; according to the classifying sand screen, the screening of stones, coarse sand and fine sand can be completed through the short screening nets and the two-layer screening structure, filling is easy due to the fact that the height is low, the occupied area of the classifying sand screen is small, and the screening efficiency is high.

Description

technical field [0001] The invention relates to a sand screening machine, more specifically a sorting sand screening machine. Background technique [0002] For example, the public number is CN207655473U, a kind of vibrating type classification sand screening machine, including base, feeding port, sand screening box, sand screening net, discharge platform, discharge port, aggregate down transmission joint, fixed frame, shaking table, Shock absorbing spring, vibration motor, etc. The uppermost side of the classification sand screening machine is provided with a material inlet, three sand screening boxes and three discharge platforms. The edge of the discharge platform is provided with a discharge port. The pore diameter gradually increases, and the sand screening machine and the discharge platform have a 20° inclination angle compared to the base. This sorting sand screening machine can quickly classify sand with different particle sizes, reduce manual labor, and improve scre...

Problems solved by technology

The uppermost side of the classification sand screening machine is provided with a material inlet, three sand screening boxes and three discharge platforms. The edge of the discharge platform is provided with a discharge port. The pore diameter gradually increases, and the sand screening machine and the discharge table have a 20° inclination angle compared with the base. This sorting sand screening machine can quickly classify sand with different particle sizes, reduce manual labor, and improve screening efficiency; The machine has three layers and the sand screen needs to be long to fully screen the sand. It is too high to add sand and the floor area is too large.
