[0036] Embodiment Two

[0037] Please refer to Figures 1-7, and on the basis of the first embodiment, it is further obtained that the limiting mechanism 3 includes a limiting rod 31. The limiting rod 31 is fixedly connected to the front side of the storage box 211. A connecting shaft 32 is rotatably connected to the outer periphery of the limiting rod 31. A fixing pin 33 is threadedly connected inside the connecting shaft 32. The rear side of the fixing pin 33 is threadedly connected to the inside of the filter box 214. A circular groove is formed in the outer periphery of the limiting rod 31. The connecting shaft 32 is rotatably connected to the circular groove, which is convenient for the circular groove to limit the connecting shaft 32 and make the rotation of the connecting shaft 32 more stable.

[0038] During the actual operation process, when this device is used, first make the baffle 2194 in a closed state inside the storage box 211, and then put the raw materials for making emulsion explosive into the storage box 211 through the hopper 216. When the mixing work needs to be carried out, the moving frame 219 threadedly connected to the outer periphery of the bidirectional threaded rod 218 is driven by the first servo motor 217 to move in the limiting grooves inside the first fixing frame 215 and the second fixing frame 2193. When the moving frame 219 moves, it will drive the baffle 2194 to slide in the chute inside the storage box 211 through the connecting frame 2191, so that the baffles 2194 are in an open and closed state. Through the size of the open and closed position, the raw materials inside the storage box can be quantitatively fed. In this way, the feeding work is carried out reciprocally. When the moving frame 219 moves, it will slide on the outer periphery of the sliding rod 2192. The sliding rod 2192 can further ensure the stability of the moving frame 219 when it moves. The raw materials after feeding will enter the filter box 214 for filtering work. The raw materials after filtering will enter the mixing box 1 through the connecting pipe 213 for mixing work. The second servo motor 221 drives the stirring rod 223 fixedly connected to the outer periphery of the rotating rod 222 to rotate, so that the raw materials can be mixed under the action of the stirring rod 223. At the same time, when the stirring rod 223 rotates, it will drive the scraper 225 to rotate through the fixing rod 224. Under the action of the scraper 225, the raw materials attached to the inner wall of the mixing box 1 will be cleaned to prevent the raw materials from adhering and solidifying and affecting the next mixing effect. When the filter box 214 needs to be cleaned or replaced after long-term use, just remove the fixing pin 33 and rotate the connecting shaft 32 in the circular groove on the outer periphery of the limiting rod 31 to make the connecting shaft 32 in a horizontal state, then the limit of the filter box 214 can be released, and the filter box 214 can be cleaned and replaced. When the raw material mixing is completed, the collecting device can be placed at the bottom of the feeding pipe 4 to collect the raw materials.
