Coordinated type vibrating screen

Abstract

The invention discloses a coordinated type vibrating screen. The coordinated type vibrating screen comprises a stand, a first screen body and a second screen body, wherein the first screen body is connected to the stand through a spring; the second screen body is connected with the first screen body through a spring; the coordinated type vibrating screen further comprises a crank, a connecting rod, a first collecting tank connected to the stand, a second collecting tank and a third collecting tank; the first screen body and the second screen body are obliquely arranged; the first screen body, the connecting rod, the crank and the second screen body are sequentially connected to a form a crank and connecting rod mechanism; the first collecting tank is arranged at the lower end of the first screen body; the second collecting tank is arranged at the lower end of the second screen body; the third collecting tank is arranged below the second screen body. According to the coordinated type vibrating screen disclosed by the invention, the vibration on the second screen body is transferred to the first screen body through the crank and connecting rod mechanism, so that resonance is avoided and respective driving by means of two driving mechanisms is also avoided, and thus the cost is relatively low. The first collecting tank and the second collecting tank are respectively arranged at the lower ends of the first screen body and the second screen body, so that materials on the first screen body and the second screen body are conveniently collected and no manual collection is needed.

Description

technical field [0001] The invention belongs to the technical field of movable sieves. Background technique [0002] The vibrating screen is a device that makes materials smaller than the screen hole fall from the screen through the reciprocating motion of the screen, and is widely used in the screening of materials. [0003] Existing vibrating screens usually include two or more layers of screen mesh, and resonance needs to be avoided during vibration. Because the resonance amplitude will increase rapidly, the spring will be seriously overloaded and its life will be shortened. Therefore, when driving the two screens, two driving devices are often used to drive the two screens respectively. However, the price of driving devices such as motors or hydraulic rods is relatively high, and such a structure will indirectly increase the cost of material screening. [0004] After the screening is completed, the materials larger than the sieve holes will remain on the sieve, and th...
