Background

A core box is a container that stores cores taken out of a drill. In geological exploration such as hydrology, mining and the like, the rock cores taken out of the drill holes are sequentially placed in a rock core box and serve as important geological record data to be stored for a long time, and accurate and reliable data are provided for research on mine exploration, deep resources or engineering geological conditions.

Most of the existing rock core boxes are open box bodies processed by materials such as plastics, wood and the like, so that the rock cores can be conveniently observed and placed. However, the existing open core box enables the core to be always exposed in the air in long-term sample retention and storage, and is easily affected by the external air to cause weathering phenomenon, and particularly, the cores such as argillaceous sandstone and mudstone with poor water quality are often disintegrated after being exposed for a period of time to affect core detection; in addition, the length of the tape or the ruler needs to be measured by an equivalent tool every time during detection, and the operation is inconvenient. Therefore, how to design a multifunctional core box which can not only visually read the length, but also prevent the core from weathering is an important problem to be solved in the geological exploration industry.

The following describes embodiments of the present invention in detail with reference to the drawings, which are implemented on the premise of the technical solution of the present invention, and detailed embodiments and specific operation procedures are provided, but the scope of the present invention is not limited to the following embodiments.

As shown in fig. 1 to 4, the multifunctional core box of the present invention comprises

The core box body 1 is formed by casting the core box body 1 integrally, and the core box body 1 is provided with an upper opening;

the box cover 2 is hermetically buckled at the upper opening, one side of the box cover 2 is hinged with the core box body 1 through a hinge, and the box cover 2 and the core box body 1 enclose a storage space for storing the core;

the separating assembly comprises a plurality of separating plates 3 which are arranged in the core box body 1 along the length direction of the core box body 1, the left side edge and the right side edge of each separating plate 3 are respectively and fixedly connected to the left side wall and the right side wall of the core box body 1, and the separating plates 3 and the bottom wall of the core box body 1 are arranged in a clearance way from top to bottom so as to ensure that a friction cloth 4 which is described later can move back and forth on the bottom wall of the core box body 1; the core box body 1 is divided into a plurality of storage cavities by a plurality of partition plates 3 at intervals in the front and back, and a core can be stored in each storage cavity;

the air inlet and outlet unit is arranged on the box cover 2, is communicated with the storage space and is used for vacuumizing the storage space; and

a drive assembly, the setting is in the bottom of core box 1, and drive assembly drives the core and is depositing the intracavity and rotate to directly observe the core in core box 1 reduces the unpacking number of times.

As shown in fig. 1 and 4, the driving assembly includes a first reel 5 rotatably disposed in the core box 1 (both ends of the first reel 5 are rotatably connected to the left and right side walls of the core box 1 through bearings), the first reel 5 is close to one long side of the core box 1 and parallel to the length direction of the core box 1; the second reel 6 is rotatably arranged in the core box body 1 (two end parts of the second reel 6 are rotatably connected with the left side wall and the right side wall of the core box body 1 through bearings), the second reel 6 is close to the other long side of the core box body 1 and is parallel to the length direction of the core box body 1, and the first reel 5 and the second reel 6 are spaced front and back; and a rubbing cloth 4 laid on the bottom wall of the core case 1, one end of the rubbing cloth 4 being wound on the first reel 5 and the other end thereof being wound on the second reel 6. During operation, the accessible rotates first spool 5 and second spool 6 and drives rubbing cloth 4 and remove on the diapire of core box 1, because frictional force between rubbing cloth 4 and the core is great, can drive the core and rotate at its corresponding storage cavity in rubbing cloth 4 removal in-process to observe the core.

As shown in fig. 1, the outer ends of the first reel 5 and the second reel 6 are both provided with a crank 7 convenient for operation, the friction cloth 4 can be moved back and forth in the core box body 1 by rotating the crank 7 on the first reel 5 and the crank 7 on the second reel 6, and then the core is driven to rotate in the storage cavity, so that the operation is simple and convenient.
