As preferably, the angle between described shower nozzle and the spray gun is 150 ~ 170 degree.
As preferably, described fixed part comprises the vehicle frame that can move freely along steel pipe and described spray gun length direction, be provided with fixed base on this vehicle frame, be provided with rotating shaft free to rotate in this support, the front end of described rotating shaft is provided with for the master of clamping steel pipe uncovered, also is provided with in the described rotating shaft for being connected with described drive division and driving the connector that described rotating shaft is rotated with this; Described rotating shaft and main uncovered center are provided be used to the through hole that passes described shower nozzle and spray gun.
As preferably, described fixed part comprises also with described master is uncovered and is oppositely arranged and is held on respectively the auxiliary uncovered of steel pipe two ends with uncovered the matching of this master that this is auxiliary uncovered free to rotate.
As preferably, the uncovered and auxiliary uncovered cross section of described master is horn-like.
As preferably, described auxiliary uncovered relatively fixing by deformation direction Flexible Connector and the described stock support consistent with the steel pipe length direction.
As preferably, described auxiliary uncovered central axis is provided with outage.
As preferably, described drive division is the motor that is connected with decelerator.
In sum, the utility model shower nozzle does not adopt scatter head, lead directly to head and only adopt, be that a spray orifice only is set on the shower nozzle, and the diameter of spray orifice and spray gun internal diameter are basically identical, and shower nozzle is obliquely installed with the angle of one 10 ~ 30 degree, after this angle can make steel sand be ejected into steel pipe inner wall, can because angle too small polishing dynamics be inadequate, steel sand be rebounded back impact to the shower nozzle injury with to sand flow.
Therefore the utlity model has following advantage:
1, steel sand stream is little to the shower nozzle wearing and tearing, the shower nozzle long service life;
2, sand flow only depends on the uniformity of steel pipe inner wall polishing and the uniformity of steel pipe rotary speed is easy to control and effective.
