[0048] 1. In this invention, the material to be tested is placed into the crushing cylinder, and then the drive motor drives the drive disc on the drive shaft to rotate. The three-head connecting frame on the T-shaped shaft will move horizontally through the positioning rod. The left L-shaped rod and the right L-shaped rod on the three-head connecting frame will be pushed by the left push rod and the right push rod, so that the left L-shaped rod and the right L-shaped rod are in a reciprocating state.

The crushing blocks further crush the material at the bottom of the crushing cylinder. Then, the valve is opened, and the material in the crushing cylinder falls into the detection chamber on the detection plate through the discharge pipe. By intermittently opening the valve and using the cooperation of the small gear and the large gear ring, the detection plate is rotated, allowing the material to be tested to be placed into the multiple detection chambers on the detection plate in sequence, ensuring that the material in the multiple detection chambers can be tested sequentially.

[0050] 3. In this invention, when the detection disc rotates, it will drive the positioning frame rod to rotate synchronously. The pressure roller on the positioning frame rod will move synchronously. When the pressure roller rotates to the position of the pressure plate, through the continuous movement of the pressure roller and the cooperation of the pressure roller and the arc block, the pressure plate on the arc block will descend synchronously. The detector on the connecting plate will slowly descend to the position of the detection chamber. By adjusting the distance between the detector and the detection chamber, the effect of microbial detection can be improved.
