[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figure 1-3 A sand processing equipment for metallurgical casting includes a shell 1, a feed port is provided on the top of the shell 1, a landslide 2 is provided below the feed port, a sieve hole is provided on the inner bottom wall of the shell 1, a vibration motor 9 is fixedly mounted on the shell 1, and a casting sand collecting box 13 is provided below the sieve hole. The vibration motor 9 drives the shell 1 to vibrate, and the sand casting in the shell 1 vibrates along with it. During vibration, the sand on the sand casting will fall from it and enter the casting sand collecting box 13 below through the sieve hole.

[0017] A rotating shaft 6 is provided above the sieve hole. The rotating shaft 6 is driven by a motor 5 fixed to the outside of the housing 1. A turntable 7 is provided on the rotating shaft 6, and a whipping soft strip 8 is fixedly connected to the turntable 7. A groove 14 is provided on the side wall of the turntable 7. A plurality of annular countersunk holes 15 are provided on the inner wall of the groove 14. The whipping soft strip 8 is inserted into the countersunk holes 15 and one end of the countersunk hole is knotted. The knotted end cannot pass through the countersunk hole 15. The whipping soft strip 8 is a nylon rope. The nylon rope is relatively soft and has a strong texture. It can withstand a lot of external forces and is used to whip the surface of the sand casting to remove the casting sand accumulated on the surface, so that the sand attached to the sand casting can be cleaned more cleanly, thereby improving the reuse efficiency of the sand.

[0018] A discharge port 3 is provided on the side of the shell 1 away from the landslide 2 , and a flip-open baffle 4 is provided outside the discharge port 3 . The baffle 4 is opened to take out the casting that has passed through the vibrating screen sand from the discharge port 3 .

[0019] A shock-absorbing device is provided at the bottom of the housing 1. The shock-absorbing device includes a coaxially arranged sleeve 10 and a second sleeve 11. Sleeve 10 is fixed to the bottom of the housing 1. An insertion shaft is inserted between sleeves 10 and 11. A spring 12 is sleeved on the insertion shaft. The two ends of the spring 12 are limited between sleeves 10 and 11. The spring 12 relieves the force on the housing 1, reducing the impact of the vibration motor 9 on the ground.

[0020] Working principle: The utility model is a sand processing equipment for metallurgical casting. When in use, the sand casting is passed from the feed port along the landslide 2 and into the shell 1 along the landslide 2. The vibration motor 9 drives the shell 1 to vibrate, and the sand casting in the shell 1 vibrates together. During vibration, the sand on the sand casting will fall from it and enter the casting sand collection box 13 below through the sieve hole. At the same time, the motor 5 drives the turntable 7 and the whipping soft strip 8 to rotate. The whipping soft strip 8 whips the surface of the sand casting to remove the casting sand accumulated on the surface, so that the sand attached to the sand casting can be cleaned more cleanly, thereby improving the reuse efficiency of the sand.
