Single tooth single impact rock crushing experimental device

Abstract

The invention provides a single-tooth single-impact rock crushing experimental device. The single-tooth single-impact rock crushing experimental device comprises a drop-hammer impact loading unit, a base and a data acquisition unit, wherein the drop-hammer impact loading unit comprises a vertical guide rail, an impact hammer, a tapered sleeve, a spring, a tapered pressing block, a pressing head and a pressing head fixed seat; the impact hammer is arranged on the guide rail in a sliding manner; the tapered sleeve comprises an upper strengthening cylinder and a lower cone; the upper strengthening cylinder is internally provided with the spring; the lower end of a resin track is inserted into the upper strengthening cylinder; the lower cone is sleeved above the tapered pressing block; the pressing head fixed seat is arranged below the tapered pressing block; the pressing head is mounted on the bottom face of the pressing head fixed seat; the data acquisition unit is arranged between the tapered pressing block and the pressing head fixed seat; the base is arranged below the pressing head. The single-tooth single-impact rock crushing experimental device is simple in structure and convenient to operate; the experimental device is used for researching a single-tooth singe-time rock crushing condition under a low power consumption condition and provides experimental evidence for a drill bit single-tooth structure, rock crushing power consumption, effective range of lunar surface impact loads and the like.

Description

technical field [0001] The invention relates to an experimental device for testing rock impact rock crushing, in particular to a single-tooth single impact rock crushing experimental device under the condition of low power consumption. Background technique [0002] In the prior art, the impact rock breaking experiment device is mainly aimed at the rock breaking experiment under the action of large impact energy, and is used in the fields of oil drilling and geological drilling. Most of the movement of the hammer in the impact test is realized by hydraulic system or pneumatic way. Due to the large impact energy, the requirements for the experimental device are high, the structure is complex, the overall structure size is large, the cost is high, and the manufacture and installation are inconvenient. [0003] Drilling and core drilling on the lunar surface has strict requirements and restrictions on power consumption. The existing impact test equipment cannot meet the rock fr...

Problems solved by technology

Due to the large impact energy, the requirements for the experimental device are high, the structure is complex, the overall structure size is large, the cost is high, and the manufacture and installation are inconvenient

[0003] Drilling and core drilling on the lunar surface has strict requirements and restrictions on power consumption. The existing impact test equipment cannot meet the rock fragmentation research under low power consumption conditions, especially the impact rock fragmentation experiment requirements of single teeth and words under low power consumption conditions.
