As shown in fig. 3 and 4, the sliding pin 18 is inserted into the lower end of the sliding column 23, the waist-shaped hole 21 through which the sliding pin 18 is inserted and which can pass freely is formed in the telescopic sleeve 22, and the sliding pin 18 slides in the waist-shaped hole 21, so that the sliding column 23 can be prevented from being separated from the telescopic sleeve 22.
The working principle of the invention is as follows: the worker places sand blanks which are not separated from the casting in a placing groove 9 at the top of the rotary seat 5, then starts two clamping cylinders 6, shortens the cylinder rods of the clamping cylinders 6, drives the floating plate to move downwards, enables the copper blocks to move downwards and prop against the surfaces of the sand blanks, and further fixedly clamps the sand blanks;
the motor 20 is started, the motor 20 drives the rotating shaft 27 to rotate, the rotary seat 5 drives the sand blank to rotate, the sand blank is subjected to centrifugal force, the sand on the sand blank generates opposite friction force with the surface of a casting piece under the action of the centrifugal force, the rotary seat 5 drives the roller 13 to alternately roll in the upper end face of the lifting ring 14 and the roller rolling groove 10, when the roller 13 rolls on the upper end face of the lifting ring 14, the lifting ring 14 is driven to move downwards, the knocking post 11 is separated from contact with the rotary seat 5, when the roller 13 rolls in the roller rolling groove 10, the elastic potential energy accumulated by the second spring 29 is released, the lifting ring 14 can be driven to move upwards rapidly, the knocking post 11 can knock the rotary seat 5, vibration force is generated between the rotary seat 5 and the sand blank, the vibration force is transmitted between the casting piece and the opposite face, the separation efficiency of the casting piece can be improved, the separated sand is thrown onto the inner wall of the fixed bin 3 under the action of the centrifugal force, impact force is generated on the inner wall of the fixed bin 3, and the sand is crushed and the large volume of the sand can be crushed through the crushing outlet 2 to collect the sand through the crushing outlet 2;
in addition, the rotation of the rotation shaft 27 makes the floating ring 24 rotate synchronously, and the fixed ring 31 is in a static state, so that the fixed ring 31 and the floating ring 24 rotate relatively, thus the balls 12 can roll alternately in the upper end surface of the floating ring 24 and the ball rolling groove 30, when the balls 12 roll to the upper end surface of the floating ring 24, the floating ring 24 moves downwards, the first spring 28 is compressed, the first spring 28 stores elastic potential energy, and when the balls 12 roll in the ball rolling groove 30, the elastic potential energy stored by the first spring 28 is released, the floating ring 24 and the pressing roller 26 can be driven to move upwards, the reciprocating movement of the floating ring 24 up and down can be driven to further drive the pressing roller 26 to move up and down, and fine sand can be extruded when the pressing roller 26 reciprocates up and down.
