The invention relates to a rectilinear vibrating screen for two groups of split seat-type vibration exciters, which belongs to the field of vibrating screening machines. The invention aims to solve the problem of unfavorable stress condition at the screen frame of the rectilinear vibrating screen, and the problem of poor self-synchronizing effect of the two-shaft vibration exciter. The screen frame of the vibrating screen is provided with two vibration exciter mounting beams with a large space, each mounting beam is provided with one group of single-shaft seat-type vibration exciters, the rotation directions of the main shafts of the two single-shaft seat-type vibration exciters are opposite, and the two single-shaft seat-type vibration exciters are respectively connected with motor transmission gears positioned on one or two sides of the screen box; the main shaft of the vibration exciter is installed on the cabinet of vibration exciter through two bearings, and two eccentric blocks are installed on both ends of the main shaft; the two corresponding single-shaft seat-type vibration exciters are assembled together through a bearing beam; and the end of the bearing beam is provided with a wedge-shaped adjusting mechanism capable of fine adjusting the joint gap of the two single-shaft seat-type vibration exciters. In the invention, the vibration exciters can be arranged at a wide space; and the invention has the characteristics of reasonable structure, good synchronizing effect, convenient installation, maintenance and adjustment of the vibration exciters, and the like. The invention is suitable for large rectilinear vibrating screens in various screening operations.
Description
Technical field: [0001] The invention belongs to the field of vibrating screening machinery, and mainly relates to a two-component body in which the box seat type vibrating exciter of a linear vibrating screen is split, which can greatly improve the stiffness of the vibrating screen frame and improve the self-synchronous operation effect of the vibrating exciter. Seat exciter linear vibrating screen. Background technique: [0002] In the existing linear vibrating sieve box-type vibrators, two types of two-axis self-synchronization or forced synchronization with gears are generally used, and both achieve linear vibration trajectories. The box body of these two box-type exciters is an integral casting, the two main shafts are installed on an integral box body through four bearings, and the four eccentric blocks are respectively installed on the main shaft. With the increase of the size of the vibrating screen, the size and weight of the exciter are also increasing, which brin...
