[0028] Example 1: The existing rock cuttings analysis device for oil logging is not convenient for cutting and grinding rocks of different sizes. To solve this technical problem, this embodiment discloses the following technical content:

[0029] A rock cuttings analysis device for oil logging that is convenient for cutting rocks includes an analysis box 1, a moving mechanism 2, a rotating mechanism 4, and an auxiliary component 8. The moving mechanism 2 is installed at the bottom end of the analysis box 1, the inner side of the moving mechanism 2 is connected to a connecting plate 3, the rotating mechanism 4 is installed in the connecting plate 3, the top of the rotating mechanism 4 is installed with an automatic telescopic rod 5, the output end of the automatic telescopic rod 5 is fixedly connected to a sample box 6, the top of the inner side of the analysis box 1 is fixedly installed with an analysis device 14 and a lighting device 15, the right side of the analysis box 1 is fixedly installed with an air pump assembly 16, the top of the outer side of the analysis box 1 is installed with a rock crushing box 7, the rock crushing box 7 is rotatably connected with a first bearing 9 and a second bearing 11, the outer sides of the first bearing 9 and the second bearing 11 are respectively fixedly installed with a grinding roller 10 and a cutting roller 12, and the left and right sides of the grinding roller 10 and the cutting roller 12 are respectively provided with a gear 13 and an auxiliary component 8;

[0030] like Figure 1-Figure 3 and Figure 5 As shown, the auxiliary component 8 includes a fixed plate 801, a cavity 802, a spring 803 and a slider 804. When cutting and grinding rocks, the power device fixedly installed on the rear end of the outer side of the rock crushing box 7 is started, and the output ends of the power device are fixedly connected to the first bearing 9 and the second bearing 11 respectively. The power device drives the first bearing 9 and the second bearing 11 to rotate, and the power devices on the left and right sides drive the first bearings 9 on the left and right sides to rotate relatively inward, and the power devices on the left and right sides drive the second bearings 11 on the left and right sides to rotate relatively inward. Grinding rollers 10 and cutting rollers 12 are fixedly installed on the outsides of the first bearings 9 and the second bearings 11 respectively. The two relatively rotating first bearings 9 drive the grinding rollers 10 on both sides to rotate relatively inward, and the two relatively rotating second bearings 11 drive the cutting rollers 12 on both sides to rotate relatively inward, thereby cutting and grinding the rock blocks.

[0031] When a larger rock block falls between the cutting rollers 12 on both sides, since the front and rear sides of the first bearing 9 and the second bearing 11 on the left are slidably connected to the inner wall of the rock crushing box 7, when the larger rock block falls between the cutting rollers 12 on the left and right sides, the grinding roller 10 on the left will be subjected to a force to the left, causing the cutting roller 12 on the left to move to the left, and the cutting roller 12 on the left drives the second bearing 11 to slide to the left, so that the larger rock block can be cut better. The fixed plate 801 is fixedly installed in the left and right side walls of the rock crushing box 7, and a cavity 802 is opened on the inner side of the fixed plate 801.
