Problems solved by technology

In actual engineering, it is required to complete the sampling and measurement of rock and soil blocks within ten minutes, and feed back the results to adjust the feed speed of the shield machine. sample, and then manually test, the efficiency is low, and the error of manual test is relatively large. At present, the manual measurement cycle is one to two hours, which is far from meeting the test requirements.

Embodiment 2

[0055] This embodiment discloses the working method of the automatic test device for rock and soil block point load described in Example 1: pouring a plurality of unscreened rock and soil blocks into the first screen, and the first screen is placed in the first vibration mechanism. Under the action of vibration, the rock and soil blocks are sieved. The rock and soil blocks that fall through the meshes of the first screen fall into the second screen, and the unfallen rock and soil blocks slide down the first screen and pass through the first discharge port. Falling into the second conveying mechanism, the second screen vibrates under the action of the second vibrating mechanism, the rock and soil blocks falling through the mesh of the second screen fall into the guide plate, and slide to the second conveying mechanism through the guide plate , the rock and soil blocks that do not fall from the mesh of the second screen mesh slide down the second screen to the second discharge pa...

Abstract

The invention relates to an automatic testing device and a working method for point load of rock and soil blocks. Mechanism and the second conveying mechanism, the screen is inclined, the clods leaked from the bottom screen and the clods screened by the other screens can fall into the second conveying mechanism, and the clods screened by the bottom screen can fall into the second conveying mechanism. The first conveying mechanism has a pressure testing mechanism on one side of the first conveying mechanism, and the first conveying mechanism can send the falling soil blocks into the pressure testing mechanism. The testing device of the present invention has high working efficiency and meets engineering requirements.

Description

technical field [0001] The invention relates to the technical field of experimental equipment, in particular to an automatic testing device and a working method for point loads of rock and soil blocks. Background technique [0002] The statements herein merely provide background related to the present invention and do not necessarily constitute prior art. [0003] At present, in the process of geotechnical mining, tunnel excavation, etc., it is necessary to measure the hardness of rock and soil blocks to control the feed speed of the shield machine. Therefore, it is urgent to measure the hardness of rock and soil blocks efficiently and prolong the service life of the shield machine. In actual engineering, it is required to complete the sampling and measurement of rock and soil blocks within ten minutes, and then feedback the results to adjust the feed speed of the shield machine. sample, and then manually test, the efficiency is low, and the manual test error is large. At ...
