By setting the vibrating screen and cleaning mechanism 2, the sand and impurities blocked in the sieve plate 4 can be quickly cleaned. The sand is put into the sieve plate 4, and then the motor 5 is started to drive the first meshing gear 6 to rotate. The first meshing gear 6 drives the cross push rod 8 to rotate through the mounting plate 7. The rotation of the cross push rod 8 continuously pushes the sieve plate 4. The sieve plate 4 continuously vibrates to screen the sand under the cooperation of the thrust and the elastic force reset of multiple first springs 3. When the sieve plate 4 is blocked, multiple hydraulic rods 12 are started at the same time to drive the cleaning steel brush 13 to descend so that its bottom fits inside the sieve plate 4. During the vibration of the sieve plate 4, its inside continuously rubs against the cleaning steel brush 13, so as to pick out and clean the blocked sand and impurities, avoid the sand and impurities being stuck in the sieve holes for a long time, and avoid affecting the efficiency and quality of sand screening.
[0025] The four ends of the cross push rod 8 and one side of the force block 10 are all arranged in an arc shape, a plurality of grooves 14 are opened on the other side of the sieve plate 4, a baffle 15 is slidably installed inside the groove 14, and magnetic blocks 16 that adsorb each other are fixedly installed on the top of the two baffles 15, a support plate 17 is fixedly installed on the other side of the support frame 1, a fan 18 is fixedly installed on the top of the support plate 17, a fixed frame 19 is fixedly installed on one side of the fan 18, a filter screen 20 is arranged inside the fixed frame 19, and a suction nozzle 21 is fixedly installed on one side of the fixed frame 19. By setting the four ends of the cross push rod 8 and one side of the force block 10 into an arc shape, the cross push rod 8 can be easily contacted with the force block 10 to push it. By setting the groove 14, the baffle 15 and the magnetic block 16, two openable baffles 15 are set on one side of the sieve plate 4, which can facilitate the cleaning of the picked sand and impurities outward. After the two baffles 15 are closed, they can be adsorbed and fixed by the two magnetic blocks 16 to prevent the sand from leaking out during screening. By setting the fan 18, the fixed frame 19, the filter screen 20 and the suction nozzle 21, the fan 18 is started during the vibration screening process. The fan 18 can absorb the dust caused by the vibration screening through the suction nozzle 21, and the dust is sucked into the fixed frame 19 and filtered through the filter screen 20, which can prevent the dust from floating and affecting the environment.
[0026] A second spring 22 is fixedly installed on both sides of the fixed frame 19, a fixed plate 23 is fixedly installed on one end of the second spring 22, a clamping plate 24 is fixedly installed on the fixed plate 23, a sealing strip 25 is fixedly installed on the filter screen 20, a sealing groove 26 used in conjunction with the sealing strip 25 is opened on the top of the fixed frame 19, a bottom plate 27 is fixedly installed on the bottom of the support frame 1, a collecting box 28 is arranged on the top of the bottom plate 27, a slide groove 29 is opened on the bottom plate 27, and a slider 30 slidably connected to the slide groove 29 is fixedly installed on the bottom of the collecting box 28.

At this time, the sealing strip 25 is inserted into the sealing groove 26, which can seal the connection between the filter screen 20 and the fixed frame 19 to prevent dust leakage. Through the arrangement of the bottom plate 27, the collecting box 28, the chute 29 and the slider 30, the collecting box 28 is arranged below the sieve plate 4, which can facilitate the collection of the screened sand material and prevent the sand material from falling directly to the ground and being contaminated. At the same time, under the action of the chute 29 and the slider 30, the friction between the collecting box 28 and the bottom plate 27 can be reduced, making it convenient to pull the collecting box 28 out of the bottom plate 27.
[0027] In this embodiment, if Figure 1-Figure 4 As shown, the working process of a casting sand screening device provided in this embodiment is as follows:

During the vibration of the sieve plate 4, its inside continuously rubs against the cleaning steel brush 13, so as to pick out and clean the blocked sand and impurities, and prevent the sand and impurities from being stuck in the sieve holes for a long time.
[0029] In summary, in the present embodiment, according to a sand screening device for casting of the present embodiment, by setting the four ends of the cross push rod 8 and one side of the force block 10 to be arc-shaped, the cross push rod 8 can be conveniently contacted with the force block 10 to push it, and by setting the groove 14, the baffle 15 and the magnetic block 16, two openable baffles 15 are set on one side of the sieve plate 4, which can facilitate the cleaning of the picked sand and impurities outward, and after the two baffles 15 are closed, they can be adsorbed and fixed by the two magnetic blocks 16 to prevent the sand from leaking out during screening, and by setting the fan 18, the fixed frame 19, the filter screen 20 and the suction nozzle 21, the fan 18 is started during the vibration screening process, and the fan 18 can absorb the dust caused by the vibration screening through the suction nozzle 21, and the dust is sucked into the fixed frame 19 and filtered through the filter screen 20, which can prevent the dust from floating and affecting the environment, and by setting the second spring 22, the fixed plate 23 and the clamping plate 24, the filter screen 20 is movably set in the fixed frame 1 9, and then the filter screen 20 is clamped by the two clamping plates 24 under the support of the second spring 22 and the fixing plate 23, so that the filter screen 20 is fixed in the fixing frame 19, and when the two clamping plates 24 are pulled to both sides, the clamping of the filter screen 20 can be disengaged, so that it can be taken out of the fixing frame 19 for cleaning. Through the setting of the sealing strip 25 and the sealing groove 26, after the filter screen 20 is installed in the fixing frame 19, the sealing strip 25 is inserted into the sealing groove 26, so that the connection between the filter screen 20 and the fixing frame 19 can be sealed to prevent dust leakage. Through the setting of the bottom plate 27, the collecting box 28, the chute 29 and the slider 30, the collecting box 28 is arranged below the sieve plate 4, which can facilitate the collection of the screened sand material and prevent the sand material from falling directly on the ground and being contaminated. At the same time, under the action of the chute 29 and the slider 30, the friction between the collecting box 28 and the bottom plate 27 can be reduced, so that the collecting box 28 can be pulled out from the bottom plate 27.
