After the temperature is lowered, it can also promote the cooling of the vibration motor to a certain extent, which is beneficial to avoid overheating of the vibration motor due to excessively high shell temperature. The heat transferred to the shell by the hotter clay sand attached to the surface of the casting is dissipated by the pressurized nozzle. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] In a specific implementation, a high-pressure valve is provided at one end of the hose away from the electromagnetic three-way valve 21. The technician controls the switch of the high-pressure valve to flush the first inclined plate 10 with the hose. After the clay sand on the casting is recovered, the hose can also be used to effectively flush the slope of the fence 6 and the bottom of the shell 1.

[0058] Working principle of the present invention:

[0059] When the present invention is in use, firstly, the jack bracket after the initial sand falling is placed on the top of the shell 1 away from the end of the collection box 7, and then the vibration motor 24 is turned on. After being turned on, the vibration motor 24 will transmit the vibration to the shell 1, and then transmit the vibration to the casting through the fence 6, so as to vibrate off the clay sand adhering to the casting. It should be noted that the casting is a jack bracket. After the jack bracket is cast, the clay sand around the jack bracket will be removed first, but some clay sand that is not easy to clean will be attached to the surface of the jack bracket. Since the temperature of the casting has not been reduced after casting, it is not easy to clean. Manual cleaning is prone to burns. If the casting is cleaned after it is completely cooled, the clay sand will be tightly attached to the surface of the casting, increasing the difficulty of cleaning.

[0060] The clay sand attached to the surface of the casting is shaken off by the vibration of the vibration motor 24, so that the clay sand attached to the surface of the casting is recovered. The clay sand shaken off the casting will fall onto the bottom wall plate of the shell 1 through the gap in the fence 6, and then fall into the funnel 12 through the inclined surface at the bottom of the shell 1, and finally be discharged through the leakage pipe 8. During this process, the vibration emitted by the vibration motor 24 will, on the one hand, shake the clay sand that falls on the inclined surface at the bottom of the shell 1 into the funnel 12, which is conducive to promoting the discharge of the clay sand on the inclined surface. At the same time, the vibration can also vibrate the clay sand in the funnel 12 through the leakage pipe 8, which promotes the discharge of the clay sand by the funnel 12 and the leakage pipe 8. Secondly, the setting of the vibration motor 24 and the shell 1 can also effectively prevent the casting from contacting the technicians, and can effectively prevent the technicians from being scalded.

[0061] As the vibration motor 24 vibrates, the vibration motor 24 will move the casting from the fence 6 toward the collection box 7. When the casting is separated from the fence 6, the casting will fall on the first inclined plate 10. The vibration can be used to shake off the residual powdered clay sand on the casting. As the casting slides, the casting will have an upward movement under the guidance of the arc plate. After separating from the arc plate, the casting will fall on the second inclined plate 11. When the casting falls on the second inclined plate 11, it will collide with the second inclined plate 11. Through the collision of the casting with the second inclined plate 11, the powdered clay sand attached to the surface of the casting will be shaken off again, and the clay sand is further cleaned.

[0062] During the contact between the casting and the second inclined plate 11, the force applied by the casting on the second inclined plate 11 will cause the second inclined plate 11 to descend, and the descent of the second inclined plate 11 will in turn drive the sliding column 30 to descend. After the descent of the sliding column 30, it will drive the built-in slide plate 31 to descend, and then squeeze the water in the rectangular box body 26, so that the water in the rectangular box body 26 enters the longitudinal box body 28 through the connecting pipe 27, and is finally discharged through the water outlet 29, so that the water flow flushes on the second inclined plate 11. On the one hand, it is beneficial to flush the clay sand on the second inclined plate 11 into the collection box 7, so as to facilitate the recovery of the clay sand in the collection box 7. On the other hand, the water flow can reduce the temperature of the second inclined plate 11, and the contact between the water on the second inclined plate 11 and the casting can play an auxiliary cooling role on the casting.

[0063] After the casting slides down from the second inclined plate 11, the casting will fall into the collecting box 7, in which water is pre-placed. The water in the collecting box 7 can, on the one hand, act as a buffer for the casting during its falling process, which helps to avoid the casting that falls later and the casting that falls earlier in the collecting box 7 from falling too fast, causing a violent collision, thereby causing damage to the surface of the casting. On the other hand, the water in the collecting box 7 can be used to completely cool the casting, so that the temperature of the casting can be quickly reduced, which is convenient for technicians to take out the casting in time to observe whether it is qualified. If unqualified castings are encountered, the casting can be adjusted in time, which helps to reduce losses.

[0064] After the casting slides off the second inclined plate 11, the second inclined plate 11 will move upward under the action of the return spring 32, and the built-in slide plate 31 will also move upward. During this process, the chamber at the bottom of the built-in slide plate 31 increases, so that the chamber at the bottom of the built-in slide plate 31 can draw water from the water tank 2 through the liquid inlet pipe 13 for temporary storage. The water in the chamber below the return spring 32 and the built-in slide plate 31 can also play a shock-absorbing role for the casting when the casting falls on the second inclined plate 11. By setting the one-way liquid inlet valve and the one-way liquid outlet valve, the water flow can only enter the rectangular box body 26 from the water tank 2, and enter the connecting pipe 27 from the rectangular box body 26, which is conducive to avoiding the occurrence of water backflow.

[0065] In the process of shaking off the clay sand on the casting, the first water pump 16 and the second water pump 18 are turned on. After being turned on, the first water pump 16 will transport water to the horizontal pipe 17, and then the water will enter the built-in groove 23 through the built-in pipe 22, and finally sprayed on the top of the shell 1 through the atomizing nozzle 5, thereby performing dust reduction treatment on the top of the shell 1. In the process of falling of the water mist sprayed by the atomizing nozzle 5, the water mist will fall on the fence 6 and the casting on the fence 6. On the one hand, the casting on the fence 6 can be initially cooled down. On the other hand, through the spraying of water mist, due to the high temperature of the casting, the water mist will evaporate into water vapor in the process of contacting with the casting and dispersed to the top of the shell 1, which is beneficial to avoid the condensation of water mist into water droplets on the fence 6.

[0066] After the second water pump 18 is turned on, it is first connected to the hose wound around the hose reel 3 through the electromagnetic three-way valve 21, and then the clay sand on the first inclined plate 10 is flushed through the hose, and the clay sand is flushed into the filter tank 15. The water in the filter tank 15 flows back to the water tank 2 under the filtration of the filter screen 14. In the process of flushing the first inclined plate 10, the first inclined plate 10 is flushed in the gap between the casting and the first inclined plate 10, so that water is also adhered to the first inclined plate 10, and the casting is cooled secondary by using the water adhered to the first inclined plate 10. During this process, the technicians manually operate the device and stand on one side of the device. On the one hand, the technicians can avoid direct contact with the castings, and on the other hand, the device can be observed in real time. When there are too many castings in the collection box 7, the device is stopped in time, and then the cooled castings in the collection box 7 are taken out and transported, which is conducive to avoiding the accumulation of castings in the collection box 7 above the water surface, which causes the castings above the water surface to collide without water buffering, thereby causing damage to the casting surface. When collecting castings from the collection box 7, through the setting of the hose, when there is clay sand in the dead corner of the casting cleaning, the high-pressure valve at the end of the hose can also be used to flush the clay sand in the dead corner of the casting cleaning.

[0067] When the bottom slope of the shell 1 is overheated, the second water pump 18 is connected to the rectangular tube 19 through the electromagnetic three-way valve 21, so that the rectangular tube 19 impacts the water flow on the outer wall of the bottom slope of the shell 1 through the pressurized nozzle 20. On the one hand, the shell 1 is cooled down, and on the other hand, the impact of the water flow can also promote the vibration of the shell 1. Secondly, when the water flow is sprayed by the pressurized nozzle 20, the flow of water is used to improve the evaporation efficiency of water, and then the evaporation of water is used to cool down the temperature, so that the temperature of the water tank 2 is lower than the ambient temperature. After the temperature is lowered, it can also promote the cooling of the vibration motor 24 to a certain extent, which is conducive to avoiding the overheating of the vibration motor 24 caused by the excessively high temperature of the shell 1. The heat transferred to the shell 1 by the hotter clay sand attached to the surface of the casting is dissipated through the pressurized nozzle 20.

[0068] During the vibration of the shell 1, the damping spring 34 can effectively reduce the vibration transmission of the shell 1 to the support leg 33, and further reduce the vibration transmission to the ground. Through the setting of the water tank 2, the water in the water tank 2 can absorb the excess vibration of the shell 1, so that the energy generated by the vibration is converted into the internal energy of the water, further reducing the vibration transmission to the ground. In the prior art, by placing the device on the cement floor inside the workshop or the floor paved with a base plate, the vibration may cause damage to the cement floor or the paved floor. The setting of the damping spring 34 and the water tank 2 can help avoid this situation and reduce the damage of the device to the ground.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
