Problems solved by technology

As a key equipment on the casting production line, the large-scale vibrating table is mainly used to adapt to the sand cleaning of large castings. The existing vibrating table generally adopts an inertial vibrating table, and the inertial vibrating table adopts a single-layer vibration isolation structure. It will produce strong vibration and impact during work, causing serious environmental and noise problems
Moreover, if the design and manufacture of large-scale vibrating tables are improper, the technical level and quality will be uneven, and some may even be unusable, which will bring great losses to users.

Abstract

The invention relates to a large vibration table, comprising a vibration table, a shock excitation spring, a shock excitation body, a base and vibration motors. A shock absorption spring on which the shock excitation body is mounted is arranged on the base. The vibration motors are mounted on both sides of the shock excitation body. The operating vibration motors on both sides rotate in opposite directions. The vibration table is mounted above the shock excitation body and connected with the shock excitation body through the shock excitation spring. The exciting frequency of the invention is higher with good shakeout effect. The invention adopts a design of shock resistance of double-layer of the vibration table and the shock excitation body, thereby improving the vibration environment greatly. The vibration motor conveys vibration to the vibration table through the shock excitation spring so that the amplitude of the vibration table is resonate and amplified, which not only saves energy, but also improves the service life of the vibration motor. Only the vibration table is required to bear vibration and impact of high vibration strength while the shock excitation body only bears vibration of lower strength. The invention adopts the structure of the support spring and the elastic damper, thereby lessening the unbalancedness of vibration of the vibration table effectively.

Description

technical field [0001] The invention relates to equipment for sand treatment and regeneration in foundry workshops, in particular to a large-scale vibrating table for separating sand from sand boxes and castings after manual molding and mechanized molding pouring in large, medium and small casting molds in foundry workshops. Background technique [0002] In recent years, foundry waste sand has caused serious pollution to the environment. At the same time, the reduction of high-quality resources and the substantial increase in transportation costs have made the recycling of foundry waste sand a focus of attention of many foundry companies and foundry workers at home and abroad. With the country's increasing support for the new energy industry, the domestic wind power equipment and nuclear power equipment manufacturing industry has developed rapidly, and the manufacturing of supporting wind power and nuclear power equipment castings has also experienced great development. Acco...
