The invention discloses a pneumatic and hydraulic integrated flexible pressurizing and damping device for a
drill bit. The device comprises a shell, a
drill rod is arranged in the middle of the shell, supporting assemblies are fixedly connected to the left side and the right side of the lower portion of the shell, a screening
assembly is arranged on the right side of the
drill rod, and an
insect catching bin is fixedly connected to the left side of the screening
assembly. A
detonation bin is connected to the upper portion of the
insect catching bin through a pipeline, each supporting
assembly comprises a pressing bin and a damping bin, each pressing bin comprises a supporting column and an
extrusion sheet, telescopic springs are fixedly connected to the upper portions of the supporting columns, buckle plates are fixedly connected to the inner sides of the telescopic springs, and a first rack is fixed to the upper end of the drill rod. An oil liquid bin is connected to the upper portion of each
extrusion sheet through a pipeline, an oil passing
pipe is connected to the inner side of each supporting column through a pipeline, the lower portion of each buckle plate is fixedly connected with the screening assembly, and the screening assembly comprises a flexible film. The pneumatic and hydraulic integrated flexible pressurizing and damping device for the
drill bit has the advantages of being capable of automatically controlling pressing and damping strength and automatically collecting syrup.
