[0002] Suspension concentrates (SCs), internationally designated as SCs, are formulations in which solid pesticide technicals are uniformly dispersed in water as particles smaller than 4 microns. Unlike wettable powders (WPs), SCs are non-flammable and non-explosive, have small particle sizes, high biological activity, high specific gravity, and require smaller packaging volumes. Compared to other pesticide formulations, SCs are safer and more environmentally friendly. Therefore, SCs have become the largest-volume pesticide among new water-based formulations.

[0023] like Figures 1-4 As shown, the utility model provides a technical solution: a suspension pesticide production grinding device, including a grinding tank 1, the inner wall of the grinding tank 1 is fixedly installed with a fixed grinding disc 2, and the pesticide suspension is ground by the rotation of a dynamic grinding disc 6 and the fixed grinding disc 2. A hopper 3 is fixedly installed on the top of the grinding tank 1, and the pesticide suspension is poured into the interior of the hopper 3, so that the pesticide suspension falls on the dynamic grinding disc 6. As the dynamic grinding disc 6 rotates, the pesticide suspension can slide into the gap between the dynamic grinding disc 6 and the fixed grinding disc 2. A motor 4 is fixedly installed on the top of the grinding tank 1, and a rotating shaft 5 is fixedly installed on the output end of the motor 4. The end of the rotating shaft 5 away from the motor 4 passes through the grinding tank 1, and the rotating shaft 5 and the grinding tank 1 are connected. The through-hole is rotatably connected, and a dynamic grinding disc 6 is fixedly installed on the outer wall of the rotating shaft 5. The starting motor 4 drives the rotating shaft 5 to rotate, so that the rotating shaft 5 drives the dynamic grinding disc 6 to rotate. The interior of the grinding tank 1 is provided with a feeding mechanism 7 for improving the grinding effect. By setting the feeding mechanism 7, the pesticide suspension can be discharged into the interior of the grinding tank 1 in small amounts for many times, thereby avoiding the accumulation of the pesticide suspension on the dynamic grinding disc 6, so that the dynamic grinding disc 6 and the fixed grinding disc 2 can fully grind the pesticide suspension. The interior of the grinding tank 1 is provided with a dredging mechanism 8 for stable feeding. By setting the dredging mechanism 8, the hopper 3 can be dredged, so that the pesticide suspension inside the hopper 3 can stably fall into the interior of the grinding tank 1 for grinding.

[0024] The above-mentioned unloading mechanism 7 includes a crankshaft 71, a baffle 72, a hollow rod 73, a driven bevel gear 74, and a driving bevel gear 75; one end of the crankshaft 71 is rotatably connected to the inner wall of the grinding jar 1, and the other end of the crankshaft 71 is fixedly installed with a driven bevel gear 74, and the outer wall of the rotating shaft 5 is fixedly installed with a driving bevel gear 75. The driving bevel gear 75 meshes with the driven bevel gear 74, and the rotating shaft 5 will drive the driving bevel gear 75 to rotate synchronously when it rotates. When the driving bevel gear 75 rotates, it can drive the crankshaft 71 to rotate by cooperating with the driven bevel gear 74 meshed with it. The baffle 72 is slidably connected to the inner wall of the grinding jar 1, and the upper surface of the baffle 72 is in contact with the grinding jar The top of the inner wall of the tank 1 is fitted, and the reciprocating sliding of the baffle 72 can make the pesticide suspension inside the hopper 3 be discharged into the interior of the grinding tank 1 multiple times in small amounts, thereby avoiding the accumulation of the pesticide suspension on the movable grinding disc 6, so that the movable grinding disc 6 and the fixed grinding disc 2 can fully grind the pesticide suspension. The hollow rod 73 is fixedly installed at the bottom of the baffle 72. When the crankshaft 71 pushes and pulls the hollow rod 73 back and forth, the hollow rod 73 will drive the baffle 72 to slide back and forth on the inner wall of the grinding tank 1, and the inner wall of the hollow rod 73 is fitted against the outer wall of the crankshaft 71. When the crankshaft 71 rotates, it will fit against the inner wall of the hollow rod 73 and move back and forth up and down and push and pull the hollow rod 73 back and forth.

[0025] The dredging mechanism 8 includes an L-rod 81, a top rod 82, a cross rod 83, and a limiting groove 84; the L-rod 81 is slidably connected to the inner wall of the grinding jar 1, and the L-rod 81 passes through the grinding jar 1, one end of the L-rod 81 is fixedly installed with the top rod 82, and the other end of the L-rod 81 is fixedly installed with the cross rod 83. When the crankshaft 71 pushes and pulls the cross rod 83 back and forth, the cross rod 83 will drive the L-rod 81 to slide back and forth on the inner wall of the grinding jar 1. A limiting groove 84 is provided on the cross rod 83, and the inner wall of the limiting groove 84 fits in the crankshaft 71. The outer wall of the hopper 3 is moved by the crankshaft 71 fitting against the inner wall of the limiting groove 84 while rotating. At the same time, the crankshaft 71 pushes and pulls the cross bar 83 back and forth. The push rod 82 is located inside the hopper 3. The L rod 81 slides back and forth up and down while driving the push rod 82 to move back and forth on the inner wall of the hopper 3. The up and down reciprocating movement of the push rod 82 can squeeze the pesticide suspension inside the hopper 3 downward to avoid the pesticide suspension being blocked inside the hopper 3, so that the pesticide suspension can stably fall into the interior of the grinding tank 1 for grinding.

[0026] Working principle: Start the motor 4 to drive the rotating shaft 5 to rotate, so that the rotating shaft 5 drives the dynamic grinding disc 6 to rotate. At this time, the pesticide suspension is poured into the interior of the hopper 3, so that the pesticide suspension falls on the dynamic grinding disc 6. As the dynamic grinding disc 6 rotates, the pesticide suspension can slide into the gap between the dynamic grinding disc 6 and the fixed grinding disc 2. The pesticide suspension is ground by the rotation of the dynamic grinding disc 6 and the fixed grinding disc 2. At the same time, the rotating shaft 5 will drive the driving bevel gear 75 to rotate synchronously while rotating. When the driving bevel gear 75 rotates, the driven bevel gear 74 meshing with it can drive the crankshaft 71 to rotate. When the crankshaft 71 rotates, it will fit the inner wall of the hollow rod 73 and move back and forth up and down and grind the powder. The hollow rod 73 is pushed and pulled reciprocatingly, so that the hollow rod 73 drives the baffle 72 to slide reciprocally on the inner wall of the grinding tank 1. When the baffle 72 slides to the bottom of the hopper 3, the baffle 72 will block the hopper 3, so that the pesticide suspension inside the hopper 3 cannot fall. When the baffle 72 slides to a staggered state with the hopper 3, the pesticide suspension inside the hopper 3 will fall downward into the interior of the grinding tank 1. The reciprocating sliding of the baffle 72 can make the pesticide suspension inside the hopper 3 discharged into the interior of the grinding tank 1 multiple times in small amounts, thereby preventing the pesticide suspension from accumulating on the movable grinding disc 6, so that the movable grinding disc 6 and the fixed grinding disc 2 can fully grind the pesticide suspension, thereby improving the grinding effect of the pesticide suspension.

[0027] As the crankshaft 71 rotates, it will move in contact with the inner wall of the limiting groove 84. At the same time, the crankshaft 71 will push and pull the cross bar 83 back and forth, so that the cross bar 83 drives the L rod 81 to slide back and forth on the inner wall of the grinding jar 1. At this time, the L rod 81 will drive the push rod 82 to move back and forth on the inner wall of the hopper 3. The up and down reciprocating movement of the push rod 82 can squeeze the pesticide suspension inside the hopper 3 downward to prevent the pesticide suspension from being blocked inside the hopper 3, so that the pesticide suspension can stably fall into the interior of the grinding jar 1 for grinding.

[0028] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
