Screening mechanism of crusher

Abstract

The invention discloses a screening mechanism of a crusher. The screening mechanism comprises a base; the outer wall of the top of the base is connected with four support rod baseplates through fixed bolts; support rods are welded at the middle parts of the outer walls of the tops of the four support rod baseplates; the outer wall of one side of the top of the base is connected with a hydraulic oil cylinder support rod through a fixed bolt; the outer wall of the top of the hydraulic oil cylinder support rod is connected with a hydraulic oil cylinder through a fixed bolt; an extension rod of the hydraulic oil cylinder is near the support rods; and the outer wall of one side of the extension rod of the hydraulic oil cylinder is connected with a connecting rod through a fixed bolt. The screening mechanism is provided with multiple screens with different screen hole diameters for multistage screening; and when the screening work is performed, the screens can be driven by the hydraulic oil cylinder to shake back and forth to accelerate the screening efficiency, so that the screening effect is good, materials are not needed to reversely feed in a crushing box for multiple times of crushing, the workload of operators is reduced, and the material screening work efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of crushers, in particular to a screening mechanism of a crusher. Background technique [0002] At present, various types of crushers widely used in industrial production include jaw crushers, chain crushers, hammer crushers, ordinary roller crushers, etc. Although these equipments have their own application fields, they also have many shortcomings. , the current crusher screening device has a simple structure and a single function. The crusher is only equipped with a single screen, which cannot perform multi-stage screening on the crushed materials, and the screen is fixed on the support frame, requiring manual use of shovel lights. Stirring and shaking the materials on the screen consumes a lot of manpower and material resources, and the screening effect is poor. Most of the time, the materials that have not been screened thoroughly on the screen need to be sent back into the crushing box for multiple crus...

[0002] At present, various types of crushers widely used in industrial production include jaw crushers, chain crushers, hammer crushers, ordinary roller crushers, etc. Although the equipment has its own application fields, there are also many shortcomings. The current crusher screening device has a simple structure and a single function. The crusher is only equipped with a single screen, which cannot perform multi-stage screening on the crushed materials. And the screen is fixed on the supporting frame, it is necessary to manually stir and shake the materials on the screen with a shovel light tool, which consumes a lot of manpower and material resources, and the screening effect is poor. Send it into the crushing box for multiple crushing, the crushing and screening efficiency is low
