Material hopper with floating vibration sieve frame and thick body pumping equipment

Abstract

The invention discloses a material hopper with a floating vibration sieve frame, which comprises a sieve frame, at least three sets of elastic connection assemblies and a vibrator, wherein the sieve frame is horizontally placed in the material hopper, the top surface of the sieve frame is lower than an opening of the material hopper, the elastic connection assemblies are distributed in the material hopper, and at least support or hang the sieve frame in a floating way in the vertical longitudinal direction and the horizontal transverse direction of the sieve frame, and the vibrator is arranged on the material hopper and exerts the vibration to the sieve frame from the top of the sieve frame. The invention also discloses thick body pumping equipment. In the invention, the vibrator is directly arranged on the sieve frame, and the sieve frame is elastically connected onto the material hopper through the elastic connection assemblies. The structure is simpler, the cost is lower, and the weight is lighter. Because of the weight reduction, larger vibration amplitude can be reached under the elasticity condition with the same vibration source and the same rigidity.

Description

technical field [0001] The invention relates to a viscous body pumping equipment, in particular to a hopper with a floating vibrating screen frame of the viscous body pumping equipment. Background technique [0002] Viscous body pumping equipment, such as concrete pumps, concrete pump trucks, vehicle-mounted concrete pumps (vehicle pumps), etc., are equipment for pumping thick bodies such as concrete. [0003] When the viscous body pumping equipment is working, the viscous body runs in the pipeline under the pumping pressure, so as to establish the pumping pressure and let the viscous body reach the desired pumping position. [0004] There are often massive solids in the viscous body. Due to the limited diameter of the conveying pipeline, in order to ensure the reliability of pumping, the viscous body pumping equipment sets a grid-like screen frame at the feed hopper to filter out the viscous solids. Excessive bulky solid in the body. [0005] Due to the viscous physical c...
