DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] Embodiment 1:

[0031] Reference Figure 1-Figure 4 , a casting surface sand cleaning device, comprising:

[0032] Support frame 1;

[0033] The mounting plate 101 is fixedly connected to the support frame 1;

[0034] A rotating rod 201 is rotatably connected to the mounting plate 101;

[0037] The pressure accumulator 3 is fixedly connected to the bracket 102;

[0038] The air blowing pipe 301 is fixedly connected to the pressure accumulator 3;

[0039] Multiple groups of air blowing pipes 301 are evenly distributed on the pressure accumulator 3;

[0040] The blowing end of the blowing pipe 301 faces the casting.

[0041] A pressure relief valve 302 is provided on the air blowing pipe 301 .

[0042] It should be noted that a filter screen is connected to the air blowing pipe 301 , and the filter screen can prevent the blown sand from falling into the air blowing pipe 301 .

[0043] The support frame 1 is fixedly connected with a support rod 103 , the support rod 103 is fixedly connected with an air cylinder 4 , the air cylinder 4 is fixedly connected with an air delivery pipe 303 , and one end of the air delivery pipe 303 away from the air cylinder 4 is connected with the pressure storage cylinder 3 .

[0044] The rotating rod 201 is fixedly connected with a convex plate 5, the air cylinder 4 is slidably connected with a sliding plug 404, the sliding plug 404 is fixedly connected with a sliding rod 402, and the sliding rod 402 and the convex plate 5 are butted against each other.

[0045] A rotating wheel 2 is fixedly connected to the rotating rod 201 on the other side, and the staff can rotate the rotating wheel 2 to drive the rotating rod 201 to rotate.

[0046] One end of the slide rod 402 away from the slide plug 404 is connected to a driving wheel 4021 , and the convex plate 5 and the driving wheel 4021 abut against each other.

[0047] Reference Figure 1-Figure 4 During use, the casting is fixedly clamped on the clamping plate 6. At this time, the rotating wheel 2 is rotated, and the rotating wheel 2 will drive the rotating rod 201 to rotate. The rotation of the rotating rod 201 will drive the casting to rotate, thereby effectively throwing off the residual sand on the casting.

[0048] Reference Figure 1-Figure 4 When the rotating rod 201 rotates, the rotating rod 201 will also drive the convex plate 5 to rotate. The rotation of the convex plate 5 will push the sliding rod 402 to slide. When the sliding rod 402 slides down, it will also push the sliding plug 404 to slide down. The sliding plug 404 can push out the gas in the gas cylinder 4. The pushed out gas will be transported to the pressure accumulator 3 through the gas pipe 303 for storage.

[0049] Reference Figure 4 After rotating a certain number of times, the staff can stop rotating the wheel 2 and lay the casting flat, then open the pressure relief valve 302, and the gas in the pressure storage cylinder 3 will be instantly blown out through the blowing pipe 301, and the blown gas will hit the casting, thereby blowing off the sand on the casting, thereby improving the sand cleaning effect of the casting.

[0050] The casting is sand-cleaned by the device, and the staff no longer needs to manually knock the casting. The sand on the surface is initially thrown off by rotating the casting, and the pressure accumulation cylinder 3 is required during the rotation. After a certain number of rotations, the casting is blown through the blowing pipe 301, thereby effectively blowing off the sand, thereby improving the sand cleaning effect and efficiency of the casting.

[0055] Reference Figure 1-Figure 2 When the air blowing pipe 301 is blowing air to the casting, the staff can also start the electric telescopic rod 7, which will drive the impact plate 701 connected to its driving end to move. During the reciprocating movement of the impact plate 701, the impact plate 701 will hit the casting body, thereby assisting in shaking off the residual sand on the casting, further improving the sand cleaning effect.

[0056] Reference Figure 2 By setting the buffer pad 7011 on the impact plate 701, it is possible to effectively prevent the impact plate 701 from damaging the casting during the impact process.
