As shown in fig. 1-5, the dither fixation spring 14 is in a stretched state when the apparatus of the present invention is in an initial state;

sequence of mechanical actions of the whole device:

when the sand shaking mould starts to work, a casting needing sand stripping is placed into the placing cavity 17, the motor 32 is started, the motor 32 starts to drive the spline shaft sleeve 73 and the cam 34 to rotate through the main power shaft 71, at the moment, the cam 34 rotates to push one end of the shaking box 16 and drive the shaking fixing block 15 to overcome the tensile force of the shaking fixing spring 14 to move upwards, and simultaneously, the shaking box 16 is continuously pushed up and down along with the cam 34 so as to achieve the work of the sand shaking mould, and at the moment, sand falls down through the quicksand through cavity 21 and the sand-water separation cavity 24 in the shaking process;

when sand passes through the sand-water separation cavity 24, at the moment, because the amount of sand falling through the sand-water separation cavity 24 is large, the sand falls to drive the speed measurement friction wheel 57 to rotate, the speed measurement friction wheel 57 rotates to drive the centrifugal wheel 56 to rotate through the speed measurement transmission shaft 59, the slide block 46 starts to move outwards under the action of the tensile force of the slide block cavity 48 and pushes the centrifugal wheel push plate 49 to move backwards under the action of the centrifugal force generated by the rotation of the centrifugal wheel 56, the larger the amount of sand is, the longer the distance the slide block 46 moves is, the later the centrifugal wheel push plate 49 moves backwards under the action of the thrust of the slide block 46 and overcomes the thrust of the centrifugal push plate spring 50, at the moment, the centrifugal push plate pull rope 51 is in a loose state, and the intermediate block 53 loses the tensile force of the centrifugal push plate pull;

meanwhile, sand falls into the sand placing cavity 22 through the sand-water separating cavity 24 and the sand through cavity 23, when the sand in the placing cavity 17 is shaken completely, the flow rate of the sand is reduced, so that the sand cannot drive the speed measuring friction wheel 57 to rotate any more, the speed measuring friction wheel 57 stops rotating, so that the centrifugal wheel 56 stops rotating, the slide block 46 loses the centrifugal force of the centrifugal wheel 56 and returns to the original position, the slide block 46 does not push the centrifugal wheel push plate 49 to move any more, the centrifugal push plate pull rope 51 pulls the intermediate block 53 to move downwards to a position abutting against the sand baffle switch 52, the sand baffle switch 52 is triggered, the sand baffle switch 52 starts to trigger the baffle electromagnet 66 to generate thrust to the baffle magnet 60, the baffle magnet 60 starts to drive the sand baffle switch 61 to move backwards to a position where the sand baffle switch 61 blocks the sand-water separating cavity 24 under the repulsive force of the baffle electromagnet 66, meanwhile, the water baffle pull rope 68 is in a tight state, the water baffle 62 moves upwards under the action of the pulling force of the water baffle spring 64 to a position where the water containing through cavity 26 is not blocked any more, and at the moment, the water containing through cavity 26 is in a smooth state;

meanwhile, when the barrier magnet 60 moves backwards, the turning block pull rope 75 starts to pull the spline shaft sleeve 73 and the drive bevel gear 72 to move forwards to a position where the drive bevel gear 72 is meshed with the cleaning bevel gear 74 and the fan blade bevel gear 70, and at the moment, the drive bevel gear 72 rotates to drive the cleaning bevel gear 74 and the fan blade bevel gear 70 to rotate;

when the fan blade bevel gear 70 rotates, the fan blade bevel gear 70 drives the fan blade 29 to rotate through the fan blade transmission shaft 31, so that water in the water tank 27 can pass through the water tank through cavity 28 and the water pipe 39 and then is sprayed out of the spray head 18 through the corrugated pipe 40 and the water inlet cavity 41;

when the cleaning bevel gear 74 rotates, the cleaning bevel gear 74 rotates to drive the cleaning driving gear 36 to rotate through the cleaning transmission shaft 35, the cleaning driving gear 36 rotates to drive the cleaning driven gear 38 to rotate so as to drive the screw rod 43 to rotate, and the screw rod 43 rotates so as to drive the spray head fixing rod 42 to move forwards;

when the spray head fixing rod 42 is forwardly applied to the front end wall of the placing cavity 17, the cleaning driven gear 38 rotates to a position which is not meshed with the cleaning driving gear 36, so that the cleaning driven gear 38 stops rotating, the screw rod 43 starts to rotate reversely under the action of the screw rod return spring 44, the screw rod 43 rotates reversely to drive the spray head fixing rod 42 to move backwards, and at the moment, the spray head fixing rod 42 can be enabled to perform comprehensive cleaning work on the casting and the motor 32 is turned off.

The invention has the beneficial effects that: this application can accomplish preliminary foundry goods through the shake of shake case and take off husky operation, and the husky mould that drives through shaking off tests the speed and rubs the wheel and rotate and judge the opportunity of taking off husky action switching, it has broken away from completely to show the bold husky mould on the foundry goods when testing the speed and rubbing the wheel stall, and then automatic switch is for washing and eluting husky, realize taking off husky mode's accurate switching, guarantee to improve on the complete basis of foundry goods taking off husky and take off husky efficiency as far as possible, the degree of automation that has reached the improvement device simultaneously, the effect of the cost of manpower is saved.
