The filter cartridge 32 is connected to the air inlet end of the fan 31, the air pipe 33 is connected to the exhaust end of the fan 31, the air hole 34 is opened at the bottom of the air pipe 33, the mounting plate 35 is arranged at the top of the air pipe 33, the brush strip 36 is installed at the bottom of the mounting plate 35, and the cross beam 37 is installed at the lower part of the inner cavity of the box body 1;

[0028] The filter cartridge 32 plays a role of pre-treatment filtration when extracting external gas, while the air pipe 33 and the air hole 34 can be used for exhaust work, the brush strip 36 can be used for contact brushing and cleaning, the cooperation of the mounting plate 35 and the cross beam 37 facilitates the adjustment of the cleaning position, and a hose is connected between the air pipe 33 and the fan 31 to assist the delivery of gas and ensure the flexibility of the air pipe 33 when moving.

[0029] Among them, support plates are installed at both ends of the surface of the air pipe 33, and the top of the support plate is installed with the bottom of the mounting plate 35, so that the support plate is convenient for supporting and fixing the air pipe 33.

[0030] Among them, a through hole is provided at the outer end of the mounting plate 35. The cross beam 37 passes through the mounting plate 35 through the through hole. The surface of the mounting plate 35 is slidably connected to the cross beam 37. The through hole can ensure the stability of the movement of the cross beam 37.

[0031] Furthermore, a placement plate 4 is installed at the lower part of the inner cavity of the box body 1. Mesh plates 5 are installed around the top of the placement plate 4. The placement plate 4 is used to facilitate the placement and bearing of products, while the mesh plates 5 are conducive to the continuous downward fall of sand and dust.

[0032] During operation, the fan 31 is started in advance. When the fan 31 extracts gas, the gas will pass through the filter cartridge 32, and after being filtered, it will be discharged into the interior of the air pipe 33 through the hose and discharged through the air holes 34, and blown to the top of the placement plate 4 and the mesh plates 5. At the same time, it is necessary to pull the mounting plate 35. The mounting plate 35 will slide on the surface of the cross beam 37, and at the same time, it will drive the brush strip 36 and the air pipe 33 to move together;

[0033] When the two move, the position of the direct grasping brush and the position of the purging will be adjusted. At the same time, the sand and dust of the grasping brush and the purged sand and dust will fall downward from the mesh plates 5. While completing the cleaning, it can also assist in the collection operation of sand and dust.

[0034] In addition, a dust inlet mechanism 2 is provided on the outer side of the box body 1. The dust inlet mechanism 2 includes an extraction component, a conveying component and a dust discharging component, which can test the uniformity of dust falling during the test, so as to maximize the authenticity;

The vacuum cleaner 21 can be used as the power extraction for sand and dust, while the three-way pipe 22 is conducive to feeding. A control valve is installed at the feeding port of the three-way pipe 22. Since it has two feeding ports, two groups of control valves are provided, corresponding to the positions at the two feeding ports respectively.

[0038] In addition, the conveying component includes a conveying pipe 23 and a dust discharging pipe 24. The conveying pipe 23 is connected to the dust outlet end of the vacuum cleaner 21, and the dust discharging pipe 24 is connected to the dust discharging end of the conveying pipe 23. The cooperation of the conveying pipe 23 and the dust discharging pipe 24 is used to complete the conveying and auxiliary discharge of sand and dust.

[0039] In addition, the dust extraction component includes a dust extraction hole 25 and a fixing plate 26. The dust extraction hole 25 is formed inside the dust extraction pipe 24, and the fixing plate 26 is installed on the surface of the dust extraction pipe 24. The top of the fixing plate 26 is installed with the top of the inner cavity of the box body 1. The dust extraction hole 25 will directly discharge the sand dust to complete the dust falling work, and the fixing plate 26 is beneficial to fixedly support the dust extraction pipe 24, so as to ensure its stable operation.

[0040] When it works, directly start the vacuum cleaner 21. At this time, it is necessary to open a control valve for discharging materials of a certain size according to requirements, so that the sand dust collected at the bottom of the inner cavity of the box body 1 is extracted by the vacuum cleaner 21 through the three-way pipe 22. At this time, the other feed inlet of the three-way pipe 22 and the control valve are in a closed state, and then it is conveyed to the dust extraction hole 25 through the conveying pipe 23 and the dust extraction pipe 24, and then discharged from the dust extraction hole 25 to complete the test dust falling work.
