[0002] Pinoxaden is a new type of phenylpyrazoline herbicide. Its mechanism of action is an acetyl-CoA carboxylase inhibitor, which stops cell growth and division and destroys the lipid structure of the cell membrane, thereby leading to the death of weeds.

[0023] Working principle: First, the staff pours pinoxaden and other raw materials from the feed barrel 36 into the feed box 2. The raw materials can enter the device housing 1 through the two guide plates 42. At this time, the staff starts the first motor 32 to make the first motor 32 drive the corresponding stirring rod 4 to rotate. The stirring rod 4 drives the other stirring rod 4 to rotate synchronously through two mutually meshing second gears 31, and the rotation directions of the two stirring rods 4 are opposite, so that the stirring blades 29 on the stirring rod 4 stir and mix the pinoxaden raw materials in the device housing 1. Then, the staff sprays the emulsifier and the solvent into the two storage boxes 5 respectively, and starts the second motor 41 to make the second motor 41 drive the corresponding screw 10 to rotate. The screw 10 rotates through The second synchronous belt 40 drives the other screw 10 to rotate synchronously. Under the limitation of the optical axis on the sleeve plate 11 on the movable sleeve 7, the movable sleeve 7 can be in a horizontal moving state, so that the movable sleeve 7 drives the injection nozzle 3 to move synchronously through the collar 6. Since the spiral directions of the two screws 10 are opposite, the two injection nozzles 3 can spray the solvent and emulsifier on the oxadiazon butyl raw material in the device housing 1 in opposite directions. At the same time, the collar 6 drives the push rod 8 to move along the wave groove on the baffle 9. When the push rod 8 is aligned with the concave surface of the wave groove, the rebound force of the arc spring 14 can be used to pull the sleeve block 12 to move along the outside of the slip ring 37, so that the sleeve block 12 drives the collar 6 to rotate along the outside of the movable sleeve 7, and the push rod 8 can be pressed against The concave surface of the wave groove, at the same time, the ring 6 drives the injection nozzle 3 to swing, so that the injection nozzle 3 is tilted, and when the push rod 8 contacts the convex surface of the wave groove, the push rod 8 can drive the ring 6 to rotate and reset. As a result, as the movable sleeve 7 moves, the push rod 8 repeatedly contacts the concave and convex surfaces of the wave groove, and the injection nozzle 3 can be in a reciprocating swing state, thereby increasing the spraying surface of the injection nozzle 3, and then cooperating with the stirring blade 29 to stir the oxazolam raw material, so that the emulsifier and solvent can be evenly mixed with the oxazolam raw material. At the same time, the movable sleeve 7 can drive the sleeve 16 to move synchronously through the sleeve plate 11, and the sleeve 16 drives the L-shaped slide 15 to move in the long groove of the feed box 2, and the L-shaped slide 15 can drive the storage box 5 to move synchronously. , realizing the synchronous movement of the injection nozzle 3 and the storage box 5, ensuring the timely feeding of the injection nozzle 3 by the storage box 5, and the top cover 21 on the top of the storage box 5 drives the positioning box 22 to move synchronously, so that the transmission rod 25 in the positioning box 22 drives the first gear 27 to move along the outer side of the rack plate 28, and the first gear 27 drives the transmission rod 25 to rotate, so that the transmission rod 25 drives the spiral stirring blade 24 on the driven rod 23 to rotate through the first synchronous belt 26, and the spiral stirring blade 24 can continuously stir the solvent and emulsifier in the storage box 5, prevent the solvent and emulsifier from sinking to the bottom, ensure the addition ratio of the solvent and emulsifier, thereby achieving the effect of uniform mixing and precise feeding, and improving the processing efficiency of the oxadiazon-butyl mixture.
