When sample collection is needed, an operator firstly moves the crawler trolley 101 to a position on a mine where survey is needed, a drilling motor 201 is started, the drilling motor 201 rotates, the drilling motor 201 is driven to rotate at a high speed through a coupler 2011, a hollow drill rod 202 and a drill bit 2021, a lifting hydraulic push rod 102 is started, the lifting hydraulic push rod 102 drives the drilling motor 201 to move downwards, the drill bit synchronously rotates downwards, the hollow drill rod 202 can be driven to move towards the ground continuously through the mutual combination of the lifting hydraulic push rod 102 and the drill bit, and in the process of downward movement of the drilling motor 201, a side wall connecting arm 1032 and a limit slider 1031 vertically move downwards along a limit guide rail 103, so that the limiting effect is achieved.
When the hollow drill rod 202 moves to the designated position, the rock core required at this time is placed inside the hollow drill rod 202, and the hollow drill rod 202 continuously moves downward, the rock core continuously enters inside the hollow drill rod 202 and contacts the protective cover 4021, the protective cover 4021 is pressed to move upward, the ejector rod 402 and the partition plate 403 are pushed to move upward, and the pressing spring 4031 is pressed, so that the rock core is always in a vertical state through the protective cover 4021.
Then, the operator starts the cutting motor 303, drives the connecting bracket 3031 to rotate through the cutting motor 303, and drives the connecting seat 301 to start to rotate in a circular motion through the arched bracket 3032 after the connecting seat 301 rotates, drives the central limit seat 3021 to start to rotate after the connecting seat 301 rotates, the sliding rod 3043 on the side wall inserting rod 3041 of the limit seat 3021 moves along the rising groove 2051, the moving path is at a descending height, the sliding rod 3041 starts to move downwards, after the sliding rod 3043 is separated from the rising groove 2051, the inserting rod 3041 is clamped in the spiral guide groove 203, and the position of the inserting rod 3041 moves inwards in the rotating process because the spiral guide groove 203 is spiral, drives the limit seat 3021 to move towards the rotation center position, and the outer convex block 3022 moves along the limit rod 3012 and extrudes the reset spring 3013, so that the limit seat 3021 moves towards the core position, and the cutter 302 continuously moves in the feeding process, so that the whole rock column can be cut off.
The hollow drill rod 202 is lifted, the cutter 302 supports the rock core, the occurrence of fracture of the rock core is reduced, then the reverse rotation cutting motor 303 is operated, the connecting seat 301 is driven to start reversing, the cutter 302 at the moment can be retracted, the rock core column can automatically fall, and the connecting seat 301, the inserting rod 3041 and the sliding rod 3043 move to an initial state.
When the core column and the hollow drill rod 202 are clamped, the cutting motor 303 is continuously started reversely, the inserted rod 3041 is separated from the spiral guide groove 203, the sliding rod 3043 can move onto the rotating groove 205 along the rising groove 2051, the sliding rod 3043 can rotate along the rotating groove 205, the baffle 2052 can be continuously pressed in the moving process of the sliding rod 3043, the sliding rod 3043 is meshed with the rotating groove 205, and after the sliding rod 3043 reversely rotates, a slope formed by the baffle 2052 can move to an initial position.
When the cutting motor 303 is reversely started, the screw shaft 404 is driven to rotate, the discharging motor 4041 is installed at the bottom of the screw shaft 404, at this time, the shell of the discharging motor 4041 integrally rotates, then the discharging motor 4041 is started, the rotating speed of the discharging motor 4041 is the same as that of the cutting motor 303, but the rotating direction is opposite, the output shaft of the discharging motor 4041 is in a static state compared with the screw shaft 404 at this time, the rectangular shaft 4042 at the bottom of the output shaft of the discharging motor 4041 is spliced on the positioning cover 401, the positioning cover 401 is locked in rotation at this time, but the screw shaft 404 starts to rotate, the screw collar 4051 is driven to move downwards with the positioning cover 401 (after the rotation of the positioning cover 401 is limited, the screw collar 4051 cannot rotate synchronously, and can slide downwards in cooperation with the screw shaft 404), and when the positioning cover 401 moves downwards, the ejector rod 402 at the bottom and the protecting cover 4021 are pushed downwards, a part of the core is moved out of the hollow drill rod 202, and the operator can conveniently take the core.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present invention.
