Sand-gravel screening machine sufficient in screening

Abstract

The invention provides a sand-gravel screening machine sufficient in screening and relates to the field of construction machinery. The sand-gravel screening machine sufficient in screening comprises abase; a left supporting plate and a right supporting plate are fixedly connected to the upper surface of the base and symmetrically arranged with respect of the central axis of the base; the left side of the right supporting plate is provided with a vibration groove, and a spring is fixedly connected to the inner bottom wall of the vibration groove; and a right slide rod is fixedly connected to the end, away from the inner bottom wall of the vibration groove, of the spring and movably connected with the interior of the vibration groove. According to the sand-gravel screening machine sufficient in screening, through cooperation of a stirring motor, a transmission rod, stirring rods, a fixing block, a movable groove, a motor groove, a vibration motor, a screening tank, a rotary block, a vibration plate, a vibration rod, the vibration groove and a buffer groove, the effect that screening is more sufficient when the sand-gravel screening machine does sand and gravel screening work is achieved, and the problem that sand and gravel in an existing screening machine are stacked and cannot be screened sufficiently due to the existing screening machine screen the sand and the gravel only through vibration is solved.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a fully screened gravel screening machine. Background technique [0002] The process in which the broken material is divided into different particle sizes through one or several layers of sieve surface is called sieving. The screening machine is a vibrating screening machine that uses the relative movement between the bulk material and the screen surface to make some particles pass through the screen holes, and divide the sand, gravel, crushed stone and other materials used in construction into different grades according to the particle size. The screening process of the sieving machine is generally continuous. After the sieving raw materials are fed to the screening machine, the materials smaller than the sieve size pass through the sieve holes, which are called under-sieve products; the materials larger than the sieve size are continuously discharged from the sie...
