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 point load testing device for rock and soil blocks described in Embodiment 1: pour unscreened multiple 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 screened, the rock and soil blocks falling through the first screen mesh fall into the second screen, and the rock and soil blocks that have not fallen slide down along the first screen and pass through the first discharge port Falling into the second transmission mechanism, the second screen vibrates under the action of the second vibration mechanism, and the rock and soil blocks falling through the second screen mesh fall into the material guide plate, and slide through the material guide plate to the second transmission mechanism , the rock and soil blocks that have not fallen from the second screen mesh slide down to the second discharge p...

Abstract

The invention relates to a rock-soil block point load automatic testing device and a working method, the rock-soil block point load automatic testing device comprises a frame body, the frame body is connected with a screen mechanism composed of a plurality of screens distributed up and down, a first conveying mechanism and a second conveying mechanism are arranged below the screen mechanism, and the screens are obliquely arranged; soil blocks leaked from the lowermost screen and soil blocks screened out from the other screens can fall into the second conveying mechanism, soil blocks screened out from the lowermost screen can fall into the first conveying mechanism, a pressure testing mechanism is arranged on one side of the first conveying mechanism, and the first conveying mechanism can convey the falling soil blocks into the pressure testing mechanism. The testing device is high in working efficiency, and engineering requirements are met.

Description

technical field [0001] The invention relates to the technical field of experimental equipment, in particular to an automatic test device for rock and soil block point load and a working method. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] At present, in the process of rock and soil mining and tunnel excavation, it is necessary to measure the hardness of rock and soil blocks to control the feed speed of the shield machine, and because the cost of the shield machine used in geotechnical engineering is as high as hundreds of millions, Therefore, it is imminent 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 feed back the results to adjust the feed speed of the...
