A number of reagent bottles are transported to the filling platform by the first conveyor belt for filling, and the first conveyor belt continues to transport the next batch of reagent bottles. After the filling of the previous batch of reagent bottles is completed, the pushing plate pushes the next batch of reagent bottles onto the filling platform. During the pushing process, the previous batch of reagent bottles will be pushed to the second conveyor belt for weighing, and the conveying operation is completed in this cycle.

[0004] With respect to the above-mentioned related technologies, in the process of pushing the reagent bottle from the push plate to the second conveyor belt, and in the process of the driving mechanism driving the push plate to push the reagent bottle to the second conveyor belt, due to the small weight of the reagent bottle itself, it is very easy to tip over, thereby affecting the working efficiency.
