The processing of the air chamber bracket is mostly done by casting. After the casting is completed, a large amount of molding sand will adhere to the surface of the casting, and these surface molding sands need to be further removed.

[0003] For example, publication number CN210435345U discloses a vibrating sand-falling device for a chamber bracket casting suitable for a vehicle brake chamber, comprising a base, a frame, a screen and a vibration motor; the base has two opposite groups, and the left and right sides of the frame are respectively connected to one group of bases through the same compression spring, and the expansion and contraction direction of the compression spring is vertical; a molding sand collecting bucket is connected to the bottom of the frame; the combined force of the exciting forces of the two vibration motors is perpendicular to the upper plane of the frame; and the screen is flatly connected to the upper plane of the frame.

However, this method can only remove some molding sand that is not strongly adhered. For some molding sand that is more tightly adhered, the vibration method is not easy to make it fall off, resulting in poor sand removal effect, incomplete removal of molding sand, low sand removal efficiency, and the inability to guarantee the quality of casting processing.

[0007] Preferably, a conveyor belt is installed on one side of the base.

[0008] Preferably, a detector is provided above the conveyor belt, and one end of the detector is fixedly connected to one side of the fixed frame.

[0009] Preferably, one side of the conveyor is rotatably connected to a rotating rod, one end of the rotating rod is fixedly connected to a fixed plate, and one side of the fixed plate is fixedly connected to a fixed block.

[0010] Preferably, a mounting groove is provided on one side of the fixing block, an electric push rod is fixedly connected inside the mounting groove, and one end of the electric push rod passes through the fixing block.

[0011] Preferably, one end of the electric push rod is rotatably connected to two rotating plates, one end of the rotating plate is rotatably connected to a clamping member, and one end of the clamping member is rotatably connected to one side of the fixed block.

[0012] Preferably, a gear is fixedly connected to the outside of the rotating rod, a rack is fixedly connected to one side of the fixed frame, and the rack is meshed with the gear.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, an external air source is connected through a connecting pipe, and high-pressure air can be ejected from a nozzle through the connecting pipe and the air inlet pipe to remove the molding sand on the surface of the casting.
