Problems solved by technology

[0002] Impact crushing is one of the important methods of rock crushing. Its main test equipment includes drop hammer or pendulum impact test bench, Hobkinson pressure bar and other methods, which are more suitable for studying single impact, but for multiple impacts or continuous impacts It is difficult to conduct experimental research, and it is difficult to conduct research on the impact crushing effect under the combined action of impact and other rock breaking methods

Abstract

The invention discloses a continuous impact crushing test device. The continuous impact crushing test device comprises a fixed bracket, a pushing bracket, an impact assembly, a rotary assembly, a connecting sleeve, a drill rod, a drill bit, a sliding block, a guide rail, a pushing oil cylinder, a rock and a moving frame, wherein the pushing bracket slides up and down along the guide rail mounted on the fixed bracket through the sliding block under the action of the pushing oil cylinder, so that the drill rod and the drill bit keep in good touch with the rock; the impact effect of the device is achieved by the impact assembly; the rotation effect of the device is achieved by the rotary assembly; the crushing position of the rock is changed by the moving frame. The continuous impact crushing test device is simple in structure and easy to process and manufacture, and facilitates the measurement of impact parameters, and the continuous impact crushing test on the rock under the impact effect and the rotation effect can be realized.

Description

technical field [0001] The invention relates to a continuous impact crushing test device, which is especially suitable for studying the crushing effect of rocks under the action of impact and impact. Background technique [0002] Impact crushing is one of the important methods of rock crushing. Its main test equipment includes drop hammer or pendulum impact test bench, Hobkinson pressure bar and other methods, which are more suitable for studying single impact, but for multiple impacts or continuous impacts It is difficult to conduct experimental research, and it is difficult to carry out research on the impact crushing effect under the combined action of impact and other rock breaking methods. Contents of the invention [0003] The object of the present invention is to address the shortcomings of the prior art, and provide a continuous impact crushing test device that is simple in structure, easy to process and manufacture, easy to install and test, and realizes impact or...
