Stone vibrating screen device with good screening effect and using method thereof

Abstract

The invention discloses a stone vibrating screen device with a good screening effect and a using method thereof. The device comprises a vibrating screen body, wherein a connecting pipe is fixed to theside surface of the vibrating screen body, a buffer spring is fixed to the lower end of the connecting pipe, supporting legs are arranged at the lower end of the buffer spring, a supporting block isfixedly welded to the inner surface of the vibrating screen body, a second vibrating spring is fixed to the supporting block, a connecting block is arranged on the second vibrating spring, a first vibrating spring is fixed to one side wall of the connecting block, and the surface of the other side of the first vibrating spring is fixedly connected with the vibrating screen body. By arranging the second vibrating spring, the first vibrating spring, a guide convex block, a third vibrating spring and the connecting block, the situation that a screen plate is fixedly connected with the supportingblock, so that the movement amplitude of the screen plate is small, and the stone movement effect is poor is conveniently avoided, and by arranging a connecting plate, a clamping block and an edge block, a mounting screw rod can be conveniently prevented from rotating and loosening, and the rotation looseness of the mounting screw rod is conveniently limited.

Description

technical field [0001] The invention belongs to the technical field of stone vibrating screens, and in particular relates to a stone vibrating screen device with good screening effect and a use method thereof. Background technique [0002] In occasions such as crushing plants, vibrating screens are often used. The existing vibrating screen is mainly composed of a screen box, a spring, a vibrator, a main shaft, a sieve plate and a motor. The vibrating screen works by using the reciprocating rotation vibration produced by the vibration of the vibrator. The upper rotating weight of the vibrator causes the screen surface to produce plane circular vibration, while the lower rotating weight causes the screen surface to produce conical rotary vibration. [0003] During the use of existing vibrating screens, the sieve plate and the vibrating screen box are mostly fixed by mounting bolts. During vibratory screening, the movement range of the sieve plate is relatively limited, result...

Problems solved by technology

[0004] The purpose of the present invention is to provide a stone vibrating screen device with good screening effect and its use method, to solve the above-mentioned background technology. During the use of the existing vibrating screen, the sieve plate and the vibrating screen box are mostly connected by mounting bolts. Fixed, during vibration screening, the movement range of the sieve plate is relatively limited, resulting in a small movement range of stone materials, which affects the filtering and screening effect of stone materials, and the installation bolts may vibrate and rotate when the equipment is working, resulting in loosening of the installation bolts and affecting the firmness of the installation sexual problems
