Rotary vibrating screen

Abstract

The invention belongs to vibrating machines, and particularly relates to a rotary vibrating screen. According to an existing rotary vibrating screen, when a screen mesh is used for sieving a material, the problem that the sieving is not uniform exists; aiming at the problem, the invention provides a rotary vibrating screen. The rotary vibrating screen comprises a material feeding hole, a dustproof cover, a screen frame, a clamp, a screen mesh, material discharging holes, a material returning plate, heavy bobs, a vibrating motor, springs, a pedestal and material baffle plates, wherein the material feeding hole is formed in the top of the dustproof cover; the screen frame is combined with the screen mesh to form a screen layer; the dustproof cover is connected with the screen layer by using the clamp; the material discharging holes are formed in the two sides of the screen layer and are mutually symmetrical; the material returning plate is arranged at the lower end of the screen mesh, and is funnel-shaped; the heavy bobs are arranged at the upper end and the lower end of the vibrating motor respectively, and are rigidly connected with the sieving components; the sieving parts are elastically connected with the vibrating motor and the pedestal by using springs; the material baffle plates are arranged at the positions, which approach the material discharging holes, of the screen mesh. The rotary vibrating screen is convenient and practical; the problem that the sieving of the material is not uniform can be solved quite well.

Description

technical field [0001] The invention belongs to a vibrating machine, in particular to a rotary vibrating screen. technical background [0002] In the field of tea processing, it involves sieving the tea leaves to make the tea leaves more uniform, which is a necessary quality for high-quality tea leaves. The rotary vibrating screen is a convenient and practical screening equipment that can improve the efficiency of the tea processing process. Most of the traditional rotary vibrating sieves are designed with a single outlet, and the movement stroke of the tea leaves on the screen is adjusted by adjusting the relative angle of the weight. The tea leaves at the feed port; this will lead to uneven sieving, or the tea leaves far away from the discharge port will be sieved completely, while the tea leaves near the discharge port will be screened for too short a time to sieve completely; although reducing the amount of feed can solve this problem One problem, but reducing the feed...
