LS type vibrating sand falling machine transports the workpiece by vibration pushing, and at the same time vibrates the workpiece to shake and screen. The equipment is mainly used in automated production lines, but can also be operated by stand-alone . The equipment is suitable for casting falling sand in the production of small and medium-sized batch castings. The vibration motor generates excitation force, drives the oblique vibration of the tank, throws the material obliquely upwards, and plays a role in conveying and falling sand on the material at the same time. The use of the sieve plate also plays the role of screening, and the molding sand falls from the sieve plate and is concentrated through the tank body to the sand outlet into the downstream equipment. The structure of the machine is mainly composed of vibration tank, support frame, vibration motor, spring, sieve plate, etc.
