Exciter type inertia vibrating shakeout machine

Abstract

The invention discloses an exciter type inertia vibrating shakeout machine. The exciter type inertia vibrating shakeout machine comprises a base, a parametric vibration frame and a motor and is characterized in that vibration isolation springs are arranged between the base and the parametric vibration frame, a row of vibration isolation springs is arranged on each of two sides of the parametric vibration frame, the motor is externally arranged, an exciter system is arranged in the parametric vibration frame, and the motor is connected with the exciter system. The exciter type inertia vibratingshakeout machine has the advantages that the motor is prevented from being directly baked by high-temperature sand blocks, motor replacing is reduced, and productivity is increased greatly; by externally arranging the motor, the frame structure is optimized, the vibration resistance of the frame is increased, and the service life of the frame is prolonged; the common motor is combined eccentric blocks, the eccentric blocks are connected with an end plate through bolts, the structure of the end plate is simplified, weld joint number is reduced, welding stress is reduced greatly, and cracking possibility is lowered.

Description

technical field [0001] The invention relates to the technical field of vibration equipment, in particular to an exciter type inertia vibration shakeout machine. Background technique [0002] The inertia vibration shakeout machine is mainly used in the process of sand removal, block sand crushing and sand recovery in the sand treatment of no-hardening sand casting process. The inertial vibration shakeout machine used at this stage uses a vibration motor as the excitation source. The vibration source of the existing shakeout machine is a vibration motor, and the power source of this motor is integrated with the vibration source. Although the structure is simple and the cost is low, this kind of motor participates in vibration, and the life of the vibration motor is low. At the same time, in order to cooperate with the installation of the vibration motor, the structure is more complicated, and there are many welds, resulting in relatively large stress concentration, and the vib...

AI Technical Summary

Problems solved by technology

Although the structure is simple and the cost is low, this kind of motor participates in vibration, and the life of the vibration motor is low. At the same time, in order to cooperate with the installation of the vibration motor, the structure is more complicated, and there are many welds, resulting in relatively large stress concentration, and the vibration frame is easy to produce Cracks; the environment where the vibration motor is located is high temperature and dusty. If the internal eccentric block bearing is not properly lubricated manually, the vibration motor will be damaged, resulting in frequent replacement of the vibration motor and short overall life of the equipment.
