Description

Technical Field

[0001] The utility model belongs to the field of vibrating screening machinery, and mainly relates to a vibrator mounting beam suitable for mounting an eccentric vibrator. Background Art

[0002] There are two ways to install the existing block eccentric vibrator on the vibrating screen frame: one is to install the block eccentric vibrator on the two side panels of the screen frame, connected by a transmission shaft in the middle, and driven by a motor transmission device. The other is to set a vibrator mounting beam on the two side panels of the screen frame, and the box-type block eccentric vibrator is installed on the upper plane of the mounting beam, connected by a transmission shaft in the middle, and driven by a motor transmission device. For large vibrating screens with a screen width greater than 3 meters, these two installation structures limit the number of eccentric vibrators that can be installed, the exciting force cannot be increased, the force on the screen frame is uneven, and the overall rigidity of the screen frame is weakened due to the large size and heavy structure. Summary of the invention

[0003] The utility model aims to provide a vibrator mounting beam suitable for mounting a block eccentric vibrator, in which a plurality of block eccentric vibrators can be evenly mounted.

[0004] The utility model is realized by the following technical scheme, including end plates, longitudinal beams and connecting mounting plates, and is characterized in that: the longitudinal beams are two I-beams or trough beams composed of welded steel plates arranged in parallel, and the two ends of the longitudinal beams are welded to the end plates to form a hollow vibrator mounting beam; in the vibrator mounting beam, 1 to 3 mounting blocks of the connecting mounting plates of the eccentric vibrators are uniformly welded.

[0005] Side plate mounting holes corresponding to the screen frame side plates are processed around the end plate; 1 to 2 eccentric vibrator mounting holes corresponding to the screen frame side plates are processed in the middle position of the end plate, and fixing holes for the eccentric vibrator are processed around each mounting hole; mounting holes and fixing holes for the eccentric vibrator corresponding to the end plate are processed on each connecting mounting plate.

[0006] The I-beam formed by welding steel plates is an asymmetric I-beam, which is composed of upper and lower I-beam flat plates and I-beam vertical plates; the trough beam formed by welding steel plates can be formed by bending steel plates.

[0007] When the vibrator mounting beam is installed on the screen frame, the vibrator mounting holes on the end plate are aligned with the vibrator mounting holes on the side plate of the screen frame.

[0008] The beneficial effect of the utility model is that it can realize the uniform installation of multiple small-size bearing block eccentric vibrators according to the width of the vibrating screen frame, including installing the block eccentric vibrators at the side plate of the screen frame and in the vibrator mounting beam at the same time. It has the characteristics of compact and reasonable structure, reliable bearing operation, large vibration force, balanced force on the screen frame and strong anti-destruction ability, and the mounting beam has safety protection characteristics during the operation of the eccentric block, and can be applied to various large-scale vibrating screens.
