Quartz sand sorting equipment

Abstract

The invention belongs to the technical field of quartz sand production equipment, and particularly relates to quartz sand sorting equipment which comprises a rack and a feeding hopper. A group of screening rods penetrating through the feeding hopper are arranged on one side in the feeding hopper, the left parts of the screening rods are hinged to the side wall of the feeding hopper, and one ends, located in the feeding hopper, of the screening rods incline downwards; a box body is fixedly connected to the outer side of the feed hopper corresponding to the screening rod; a tension spring is fixedly connected between the bottom of one end of the screening rod located in the box body and the inner wall of the box body; a slag discharging opening is formed in the side, away from the screen rod, of the feeding hopper; the sieve rods are connected through a hinged structure, impact on the sieve rods can be reduced in cooperation with a tension spring, the roller of the deflector rod limits the expansion range of the free ends of the sieve rods, the expansion range of the sieve rods extruded by stones is limited, large stones are prevented from passing through gaps formed after the sieve rods are expanded, and the screening efficiency is improved. The failure of the connecting structure of the screen rod can be avoided under the condition that the screening effect of coarse screening equipment is not influenced, and the shutdown maintenance frequency of the equipment is reduced.

Description

technical field [0001] The invention belongs to the technical field of quartz sand production equipment, in particular to a quartz sand sorting equipment. Background technique [0002] Such as figure 1 As shown, the equipment used for coarse screening of quartz sand in the prior art includes a feed hopper 11 and a plurality of screen rods 12 arranged on the feed hopper 11, gaps are provided between the screen rods 12, and the fine sand flows from between the screen rods 12. The stones are discharged along the inclined sieve rod 12; [0003] Such as figure 1 As shown, as an arrangement form of the sieve rod 12, the two ends of the sieve rod 12 are connected in series through the screw 10, and are fixed by the nuts on the screw 10; At the same time, due to the different shapes of the stones, the stones or the raised parts of the stones are easy to get stuck between the screen rods 12, so that the screen rods 12 are subjected to horizontal impact at the same time. The screw...
