[0048] As Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, the swing structure 2 is provided with a detection mechanism 3 for detecting the distribution of ore pulp particles. The detection mechanism 3 includes a leakage structure 301 for ore pulp particle distribution. The leakage structure 301 detects the ore pulp particle leakage through a material conveying detection assembly 302. The leakage structure 301 includes a concave-shaped base 3011. The base 3011 is provided with a plurality of first clamping grooves 3012 connected with the first clamping blocks 2023. The base 3011 is provided with a plurality of second clamping blocks 3014 connected with the other leakage ladders 3013. The leakage ladders 3013 are arranged in a steamer structure. The leakage ladders 3013 are arranged in a concentric circle structure. The leakage ladders 3013 are arranged in a steamer structure to ensure that each leakage ladder 3013 is provided with a leakage hole or a leakage groove to facilitate the filtration and leakage of ore pulp particles. The leakage ladders 3013 are arranged in a concentric circle structure. The diameters of the leakage holes or the leakage grooves gradually decrease from large to small.

[0049] Further, the detection mechanism 3 includes a material conveying detection assembly 302. The material conveying detection assembly 302 includes a graduated measuring cup 3021.

During the operation of the slurry pump 3022, the slurry is transported to the through pipe 3016 through the delivery pipe 3033. The slurry entering the through pipe 3016 is transported to the funnel ladder 3013 for stratified filtration. The filtered water falls into the base 3011 for collection. During the slurry transport process, the oscillating structure 2 evenly distributes the slurry inside the funnel ladder 3013. When the slurry is drawn to the corresponding position, the high-pressure water pump 106 is used to inject water to add water, thereby repeating the process 2-3 times.

Directly below the electronic scale 403, a portable power supply battery 404 is provided. The drying box 402, electronic scale 403, and battery 404 are all set up using existing technology structures, which facilitates the operation of the operator.

[0052] In the above scheme, the operator collects the product from the bottom of the strainer 3013 and the measuring cup 3021 and transports it to the drying oven 402 for drying. After the product is dried, it is transported to the electronic scale 403 for weighing, and the volume of the weighed product is calculated to obtain the corresponding slurry particle distribution detection data.
