Pneumatic and hydraulic integrated flexible pressurizing and damping device for drill bit

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of pressurization and shock absorption, in particular to a flexible pressurization and shock absorption device for drill bits integrated with pneumatic and hydraulic pressure. Background technique [0002] There is a tree with sugar in nature, which is a plant called "sugar maple". This plant contains a lot of syrup. It is often necessary to hang a bucket on the tree to take out the syrup inside. It is drilled, and the pipe is inserted into the tree to collect the syrup. When the existing drill pressurization and shock absorbing device drills the hole of this kind of tree, it cannot determine its fixing force and pressing strength according to the depth of the drill hole, which is easy to cause the drill bit to be damaged. Breaking and damaging the trunk, and at the same time, the sugar in the tree cannot be collected, which wastes the drilled syrup. Therefore, a pneumatic-hydraulic integrated drill bit with...

[0002] There is a tree with sugar in nature, which is a plant called "sugar maple". This plant contains a lot of syrup. It is often necessary to hang a bucket on the tree to take out the syrup inside. It is drilled, and the pipe is inserted into the tree to collect the syrup. When the existing drill pressurization and shock absorbing device drills the hole of this kind of tree, it cannot determine its fixing force and pressing strength according to the depth of the drill hole, which is easy to cause the drill bit to be damaged. Breaking and damaging the trunk, and at the same time, the sugar in the tree cannot be collected, which wastes the drilled syrup. Therefore, a pneumatic-hydraulic integrated drill bit with flexible pressure that can automatically control the pressure and shock absorption and automatically collect the syrup is designed. Shock absorbers are necessary
