Heavy vibration screening equipment

Abstract

The invention relates to heavy screening vibration equipment, and belongs to the technical field of material conveying equipment. A vibration excitation motor used in the equipment is a double-output-shaft motor, output shafts at the two ends of the vibration excitation motor are connected with driving shafts installed on vibration exciters on the two sides of a base girder through universal jointcouplings correspondingly, an included angle not smaller than 15 degrees is formed between each driving shaft and the corresponding eccentric shaft, the driving shafts and the eccentric shafts are connected through a pair of bevel gears, the two eccentric shafts are connected through a pair of cylindrical gears, eccentric blocks installed on the two eccentric shafts are the same in structure andsize, and the generated exciting force is superposed in the direction perpendicular to a plane formed by the axes of the two eccentric shafts and counteracted in the parallel direction; and excitationforce generated by each vibration exciter coincides with the center of the corresponding side plate, main rotating components such as gears and bearings are sealed in the vibration exciters, and thethin oil lubrication performance of the vibration exciters is guaranteed. The crack resistance of the side plate is improved, the service life of the vibration exciter is prolonged, and the heavy screening vibration equipment has very remarkable advantages.

Description

technical field [0001] The invention relates to a heavy-duty vibrating screening equipment for screening materials, which belongs to the technical field of material conveying equipment. Background technique [0002] In metallurgy, mining, coal, building materials and other industries, a large number of vibrating screening equipment are used. With the development of modern industrial production, the number and scale of materials that need to be screened are increasing. Therefore, large and heavy vibrating screens are used There are more and more demands for these devices. With the popularization and use of these devices, two problems in production have become increasingly prominent, which restrict the promotion and application of these devices in production. One problem is that with the increase in the processing capacity of the vibrating screening equipment, the weight and size of the vibrating equipment will increase accordingly, so the requirements for the exciting force o...
