[0020] The support column 8 is provided with a movable plate 6 which can be raised and lowered, and the movable plate 6 is provided with a dust hood 5 which can be extended to above the workbench 2 .

[0021] In this embodiment, the vibration machine 1 is used as a power source of the entire system to generate vibration, which is a prior art and will not be described in detail here.

[0022] A motor 14 for driving the support column 8 to rotate is disposed on one side of the vibration machine 1 , and a support plate 13 is fixedly connected to the top of the motor 14 .

[0023] The motor 14 is a driving component, used to drive the support column 8 to rotate and not to provide support. The support plate 13 is a frame-type structure, used for support.

[0024] The mesh box 4 is made of elastic material, which can ensure that the casting will not cause damage to the workpiece when it is working.

[0025] The workbench 2 is fixed on the top of the vibration machine 1 and is used to carry castings and other working parts.

[0026] The support frames 3 on both sides are used to fix the net box 4 to ensure its stability during vibration.

[0027] Place the casting into the accommodating cavity of the mesh box 4, ensure that the casting is firmly fixed by the limit rod, start the vibrator 1, make the workbench 2 and the mesh box 4 begin to vibrate, and the sand particles fall off the surface of the casting and are discharged through the feed hole and the sand outlet. After the vibration is over, slide the brush plate 15 to clean the surface of the workbench 2, adjust the position and height of the support column 8 and the movable plate 6 so that the dust hood 5 can cover the area above the workbench 2, turn on the dust collection equipment, and collect the dust and fine sand particles generated during the cleaning process through the dust hood 5.

[0028] Furthermore, a movable sleeve 9 is slidably mounted on the surface of the support column 8, one end of the movable plate 6 is fixedly connected to the surface of the movable sleeve 9, a support plate 11 is arranged on the inner side of the support column 8 and at the bottom of the movable plate 6, a hydraulic cylinder 12 is fixedly connected to the support plate 11, and an output end of the hydraulic cylinder 12 is fixedly connected to the bottom of the movable plate 6.

[0029] In this embodiment, the movable sleeve 9 is slidably sleeved on the surface of the support column 8 , which provides guidance and support for the lifting and lowering of the movable plate 6 .

[0030] Before starting the vibration sand removal, adjust the movable plate 6 to an appropriate height to ensure that the dust cover 5 does not interfere with the placement of the casting. After the vibration sand removal is completed, adjust the height of the movable plate 6 as needed to make the dust cover 5 close to or contact the surface of the workbench 2 to start the cleaning process. After the cleaning is completed, adjust the height of the movable plate 6 again to facilitate the removal of the casting or the next operation.

[0031] Furthermore, slide rails 23 are provided on both sides of the workbench 2, and a sliding sleeve 21 is slidably provided on the surface of the slide rail 23. A connecting rod 22 is fixedly connected to the surface of the sliding sleeve 21. The connecting rod 22 is fixedly connected to both sides of the brush plate 15, and pull rods 10 are provided on both sides of the front end of the brush plate 15.

[0032] In this embodiment, when the workbench 2 needs to be cleaned, the pull rod 10 is pulled to drive the brush plate 15 to slide on the sliding rail 23 of the movable sliding sleeve 21, which will cause the connecting rod 22 to drive the brush plate 15 to slide along the surface of the workbench 2, thereby cleaning up the remaining sand, dust or other impurities.

[0033] Furthermore, protrusions 18 are provided at both ends of the second limiting rod 17, a plurality of first grooves 19 adapted to the protrusions 18 are provided on both sides of the inner wall of the net box 4, and second grooves 20 adapted to both ends of the first limiting rod 16 are provided at both ends of the inner wall of the net box 4.

[0034] In this embodiment, when the size of the space in the mesh box 4 needs to be adjusted, the size between the cavities can be adjusted by sliding the first limiting rod 16 and the second limiting rod 17, so as to accommodate castings of different sizes.

[0035] The height of the first limiting rod 16 and the second limiting rod 17 should be higher than the height of the casting to prevent the casting from falling during the processing.

[0036] Furthermore, a dust collecting device 7 is fixedly connected to the top of the movable plate 6 , and an air inlet of the dust collecting device 7 is connected to the dust collecting hood 5 .

[0037] In this embodiment, the dust collecting device 7 is a cartridge dust collector, which has a much higher dust removal efficiency than the old dust collector, effectively reduces the emission of harmful substances, and the air purification index reaches the world's advanced level.

[0038] Furthermore, the side walls of the first limiting rod 16 and the second limiting rod 17 are both made of elastic material.

[0039] In this embodiment, since the elastic material has good buffering performance, it can effectively reduce the collision force between the casting and the limiting rod, reduce the risk of damage to the casting and the limiting rod, and speed up the cleaning and transportation of the casting, thereby improving work efficiency.

[0040] The working principle and use process of the utility model: After the utility model is installed, the casting is placed in the accommodating cavity of the mesh box 4 to ensure that the casting is firmly fixed by the limit rod, and the vibrator 1 is started to make the workbench 2 and the mesh box 4 start to vibrate, and the sand particles fall off the surface of the casting and are discharged through the feed hole and the sand outlet. After the vibration is over, the sliding brush plate 15 cleans the surface of the workbench 2, and the position and height of the support column 8 and the movable plate 6 are adjusted so that the dust hood 5 can cover the area above the workbench 2, and the dust collection equipment is turned on to collect the dust and fine sand particles generated during the cleaning process through the dust hood 5.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
