In addition, in the description process of the embodiment of the present invention, the position relationships of the devices such as "up", "down", "front", "back", "left", "right" in all the drawings all use fig. 1 as a standard.

As shown in fig. 1, the large resin sand regeneration shakeout machine comprises an upper feeding bin, a lower material receiving bin 5 and a pair of vibration exciters 6 arranged on the side surface of the lower material receiving bin 5, wherein the pair of vibration exciters 6 are fixedly connected through a connecting shaft 13, the side surface of one vibration exciter 6 is sequentially connected with a universal coupling 7 and a vibration motor 8 through a mounting bracket 9, and the details are shown in fig. 3. This large-scale resin sand regeneration shakeout machine, motor and vibration box separation, the advantage is as follows:

1. the service life of the motor is prolonged, and the inspection and maintenance are simple, convenient and quick. The original equipment vibration motor and the screen box are directly connected, so that heat dissipation cannot be realized, dust is large, a coil is easy to damage at high temperature, and replacement and maintenance are difficult.

2. The weight of the equipment is reduced, and the energy consumption is reduced. Compared with the prior equipment, the shakeout machine with the same size has the advantages that the mass is reduced by 15 percent, and the energy consumption is reduced by 10 percent. Original design adopts vibrating motor and sieve case lug connection, because vibrating motor participates in the vibration, so whole increase in mass, required vibrational force increases, for the intensity of vibration of guaranteeing the sieve case, the material increases, the thickening.
