High Efficiency Vibrating Screen

Abstract

The invention provides a high-efficiency vibrating screen which comprises a fixed seat, a sensor mechanism, a fixed support, a feeding assembly, a drive assembly and a controller. A vibrating assemblyis carried on the fixed seat through multiple elastic pieces, and comprises a screen box; a screen mesh is arranged in the screen box; a track is arranged at the top end of the screen box; the sensormechanism is used for detecting a distribution situation of objects to be screened on the screen mesh in real time; the fixed support is fixedly connected onto the fixed seat; the feeding assembly comprises a connected feeding hopper and a flexible discharging cylinder connected to a discharge hole of the feeding hopper; the feeding hopper is fixedly connected onto the fixed support; the drive assembly comprises a fixed piece; a drive motor and a discharging ring are arranged on the fixed piece; a discharging hole of the flexible discharging cylinder is fixedly connected with the dischargingring; the fixed piece is connected onto the track in a sliding or rolling way; and the controller controls the drive motor to drive the fixed piece to move according to the distribution situation. According to the high-efficiency vibrating screen provided by the invention, the utilization of the maximum efficiency of the screen mesh is realized, and the use efficiency is improved.

Description

technical field [0001] The invention relates to mechanical equipment, in particular to a high-efficiency vibrating screen. Background technique [0002] Vibrating screen is a common material separation device, which is widely used in chemical industry, agriculture, metallurgy, construction, mining and other fields. In the prior art, vibrating screen is mainly composed of screen box, vibration exciter, suspension (or support) device and motor and so on. The motor drives the main shaft of the exciter to rotate through the V-belt, and the screen box vibrates due to the centrifugal inertial force of the unbalanced weight on the exciter. Different amplitudes can be obtained by changing the eccentric weight of the exciter. [0003] The disadvantage of the prior art is that the position of the feed hopper of the vibrating screen is fixed, that is, the particle mixture to be screened is always fixed and put on the fixed position on the screen, which leads to the fact that the scre...

[0003] The disadvantage of the prior art is that the position of the feed hopper of the vibrating screen is fixed, that is, the particle mixture to be screened is always fixed and put on the fixed position on the screen, which leads to the fact that the screen is located on the feed hopper during work. The position below is always piled up with a thicker particle mixture, and part of the area on the screen is always in a state of no particle mixture or less particle mixture. The vibrating screen in the prior art does not make full use of the screen, and its work efficiency is low
