Detailed Description

The embodiment of the device for screening crushed stone and fine sand of the present invention is further described with reference to fig. 1.

A broken stone fine sand screening device comprises a screening box 1, wherein the top of the screening box 1 is provided with a feed inlet, a screening barrel 8 is arranged in the feed inlet, driven teeth 6 are arranged on the side wall of the circumference of the top of the screening barrel 8, the top of the screening box 1 is provided with a driving motor 3, a driving gear 4 matched with the driven teeth 6 is arranged on a rotating shaft of the driving motor 3, the bottom surface and the side wall of the screening barrel 8 are screening net plates, a discharge hole is arranged at the lowest position of the inclined bottom surface of the screening barrel 8, a baffle 12 is hinged at the discharge hole, a torsional spring is arranged at the hinged position of the baffle 12 and the screening barrel 8, the top end of the baffle 12 is an everted arc plate 2, a discharge pipe 16 is hinged on the side wall in the screening box 1, one end of the discharge pipe 16 is hinged with a cylinder 15, one end of the cylinder 15 is hinged on the inner wall of the screening box 1, a discharge port 13 is arranged on the inner wall of the screening box 1 corresponding to the hinged position of the discharge pipe 16.

When fine sand screening is carried out, raw materials enter from a screening barrel 8 at a feeding hole, then a driving motor 3 works to drive a driving gear 4 to rotate, the driving gear 4 drives a driven gear 6 to rotate, so that the screening barrel 8 rotates, fine sand in the screening barrel 8 rapidly moves circularly in the screening barrel 8 and is discharged from a screening screen plate of the screening barrel 8, broken stones are left in the screening barrel 8, when screening is finished, the driving motor 3 drives a screening box 1 to reset and stop rotating, at the moment, an air cylinder 15 stretches and retracts to drive a discharge pipe 16 to rotate, so that the discharge pipe 16 turns downwards, a baffle plate 12 is pressed downwards and turned over after an arc-shaped plate 2 is pressed, so that a mouth of the discharge pipe 16 is communicated with a discharge port, because the bottom surface of the screening barrel 8 is obliquely arranged, the broken stones roll into the discharge pipe 16 under the action of gravity, are discharged from a discharge port 13 at the other end of the discharge pipe 16, and after the discharge of the broken stones is finished, the cylinder 15 drives the row material pipe 16 and resets, and baffle 12 resets again and blocks the bin outlet in the effect of torsional spring, and above-mentioned setting, usable driving motor 3 drive screening bucket 8 rotation is with higher speed the filtration rate raise the efficiency of fine sand, and can the automatic discharge rubble again after the screening finishes, uses manpower sparingly.
