[0027] The bulk material assembly 8 includes a vibration motor 81 arranged at the bottom of the distribution hopper 7, and the vibration motor 81 is used to disperse the solid additives on the distribution hopper 7 into the corresponding blending box 104. A support frame 82 is fixedly arranged on the top of the connecting rod 112, and the support frame 82 is fixed to the bottom of the distribution hopper 7. The bracket 82 is used to connect the connecting rod 112 and the distribution hopper 7, and adopts an elastic metal structure, which can avoid causing serious damage to the connecting rod 112 when the distribution hopper 7 vibrates. An inclined rod 83 is fixedly arranged on the top of both sides of the distribution hopper 7, and the other end of each inclined rod 83 is against the side of the feeding hopper 6 through a ball 84. In this way, when the vibration motor 81 vibrates, the vibration of the distribution hopper 7 will drive the two inclined rods 83 and the ball 84 to vibrate, thereby vibrating the side wall of the feeding hopper 6 91, and the oil inlet pipe 201 passes through the bottom of the blank space 105 and is connected to the oil storage space 202, wherein the blank space 105 is used to rotate the feeding port 91 to the top of the blank space 105 after the material distribution is completed, so that the other multiple blending spaces 103 can perform the blending work normally, thereby ensuring the sealing state during blending.

[0028] When the present invention is in use, in the initial state, the blank space 105 is exposed below the feeding port 91, and the remaining blending space 103 is sealed. Then, before the additive is fed through the feeding hopper 6, the lubricating oil is first transported to the spiral channel 36 through the pressurizing blade 33, and the lubricating oil is output upward through the rotation of the spiral channel 36. Then, the multiple oil distribution pipes 35 above the spiral channel 36 evenly distribute the lubricating oil to the blending box 104 in each blending space 103, and then the driving motor 31 drives the rotating part 11 to rotate through the connecting shaft 32 and the electromagnetic clutch. The advantage of this is that while the lubricating oil is output upward, the position of the feed port 91 can be adjusted by rotating the rotating part 11, so that it cooperates with different blending boxes 104. In this way, different weights of additives can be output from different blending boxes 104, thereby obtaining different sample solutions. The advantage of this is that different blending boxes 104 can be blended at the same time, thereby ensuring that the other influencing factors of the sample solution are the same, and the lubricating oil entering multiple blending boxes 104 is consistent, so that the experimental data can be obtained more accurately, and the proportion of the additives can be adjusted conveniently.
