The bottom of the base platform 12 is provided with an adjustable foot 11 to facilitate leveling. The base platform 12 and the mounting plate 17 are connected by four support columns 15. The hydraulic cylinder 18 is installed on the top of the mounting plate 17. The output end of the hydraulic cylinder 18 extends to the bottom of the mounting plate 17 and is provided with a pressure plate 16. The front side of the base platform 12 is provided with a step groove connected to the top of the base platform 12, and a waste collection box 13 is placed on the step groove. As a preferred embodiment, the waste collection box 13 is provided with a handle 14 to facilitate the removal of the waste collection box 13.

[0027] The blocking and cleaning mechanism 2 includes a door panel 21, a rear push plate module 23 and a side baffle module 22 symmetrically arranged on the left and right; the door panel 21 is arranged on the front side of the pressure testing machine 1, one end of the door panel 21 is hinged to the pressure testing machine 1, and the other end is locked to the pressure testing machine 1.

[0028] The rear push plate module 23 includes a rear support plate 233 and a push plate 231. The rear support plate 233 is installed at the top rear position of the base platform 12. A cylinder 234 is installed at the rear of the rear support plate 233. The output end of the cylinder 234 extends to the front of the rear support plate 233 and is connected to the push plate 231.
