As shown in fig. 1 to 5, the conveying pipe 1 is a metal circular pipe, a connecting pipe 2 is mounted or fixedly mounted at the tail end of the conveying pipe in a threaded manner, and a first flange 21 is fixed on the connecting pipe facing away from the conveying pipe. The high-pressure air pipe 12 is tied up and fixed on the conveying pipeline through the binding belt 11, high-pressure air enters the high-pressure air pipe, and a spray head 13 is arranged at the tail end of the high-pressure air pipe.
The same side of the conveying pipeline and the connecting pipe is provided with a separating pipeline 3 which is of a horn-shaped hollow structure, the small end of the separating pipeline is fixedly provided with a second flange plate 31, and the first flange plate and the second flange plate are fixed together through bolts. The shower nozzle is fixed on the separation pipeline and the shower nozzle partly stretch into in the separation pipeline, is fixed with annular base 32 on the outer wall of separation pipeline tip, is equipped with carousel 33 in the homonymy of connecting pipe, base, and the carousel setting is outside and the coaxial line setting with the base of separation pipeline tip, is fixed with three dead lever 37 that evenly set up along circumference on the base, and the dead lever sets up perpendicularly with the base. A hydraulic cylinder 38 is hinged on the fixed rod, and a piston rod of the hydraulic cylinder is hinged with a protrusion 333 fixed on the turntable. As shown in fig. 6 and 7, three driving grooves 331 are uniformly arranged along the circumferential direction on the turntable, three track grooves 332 are also uniformly arranged along the circumferential direction on the turntable, and the three track grooves are respectively positioned between every two adjacent driving grooves. The drive groove is a straight groove, the extension line of the drive groove does not pass through the circle center of the turntable, the track groove is an arc groove, three positioning rods 39 which are uniformly arranged along the circumferential direction are fixed on the base, and the positioning rods are positioned between the base and the turntable. One end of the positioning rod is fixedly connected with the base, the other end of the positioning rod extends into the track groove, and a nut 391 arranged on the same side of the base and the turntable is arranged on the positioning rod in a threaded manner.
