At present, when mine tailings are filled, most of the mine tailings are filled by using a pipeline and a nozzle at the end of the pipeline, the existing nozzle can effectively prevent mortar from being blocked, and the structure is simple, but the problem that the internal resistance is overlarge when the mine tailings are used is solved, and the sand blasting requirement can be met by improving the conveying pressure. In addition, the elastic sleeve made of latex in the nozzle is easy to cause sealing failure and nozzle core bonding and other problems due to aging because of being soaked in the tailing for a long time. There is therefore a need for improvements in the art.

The cylinder is a cylinder or a polygonal cylinder, the cavity is arranged in the middle of the cylinder, and the spray holes are radially and symmetrically communicated along the wall of the cavity so as to spray in multiple directions through the spray holes on the cylinder.
The closed end of the cylinder is internally provided with a screw hole, the inner end of the screw hole is communicated with the cavity, the outer end of the screw hole is open, the screw hole is internally provided with a threaded connection plug, the inner end of the plug is matched with the spring, so that the plug is rotated into the screw hole to adjust the position of the plug, and then the pressure of the spring is adjusted, so that the pressure of different pipelines is adapted, and the pressure of filling mortar is regulated and controlled.
The cylinder connecting end is internally provided with a horizontal through hole, the outer end of the horizontal through hole is open, the inner end of the horizontal through hole is communicated with the cavity and is matched and connected with a sealing ball in the cavity, and the outside of the cylinder connecting end is provided with threads so as to be in threaded connection with the mortar conveying pipe.
The sealing ball is a steel ball, the diameter of the sealing ball is larger than the horizontal through hole in the connecting end of the cylinder and smaller than the inner diameter of the cavity, and a groove is arranged on the spherical surface matched and connected with the spring so as to be matched and connected with the spring to prevent mortar from flowing back.
The utility model has the following advantages and effects: by adopting the scheme, the sealing ball and the spring realize good non-return effect, so that mortar is ensured not to flow backward and block the nozzle. Meanwhile, the sealing performance of the steel sealing ball cannot be influenced after the steel sealing ball is soaked in mortar for a long time, and the sealing effect is ensured to be effective for a long time. In addition, the pressure of the spring is further adjusted by adjusting the position of the plug so as to adapt to filling of different mortar pressures.

Detailed Description
The utility model is further described below with reference to the accompanying drawings.
The elastic non-return nozzle provided by the utility model comprises a cylinder 3, wherein a cavity 5 and a plurality of spray holes 6 are arranged in the cylinder 3, one end of the cylinder 3 is a closed end 8, the other end of the cylinder is a connecting end 1 connected with a mortar conveying pipe, a sealing ball 4 matched with the connecting end 1 is arranged in the nozzle cavity 5, a spring 7 is arranged between the sealing ball 4 and the closed end 8, so that non-return sealing is realized through the matching of the sealing ball 4 and the connecting end 1, mortar entering through the connecting end 1 is prevented from flowing backwards or blocking the spray holes 6, and meanwhile, the sealing performance is not influenced when the steel sealing ball 4 is soaked in the mortar for a long time, and the long-term and effective sealing effect is ensured;
the cylinder 3 is a cylinder or a polygonal cylinder, the cavity 5 is arranged in the middle of the cylinder 3, and a plurality of spray holes 6 are radially and symmetrically communicated along the wall of the cavity 5 so as to spray in multiple directions through the plurality of spray holes 6 on the cylinder 3;
a screw hole is formed in the closed end 8 of the column body 3, the inner end of the screw hole is communicated with the cavity 5, the outer end of the screw hole is open, a plug 9 is connected in the screw hole in a threaded manner, the inner end of the plug 9 is matched with the spring 7, so that the plug 9 is rotated into the screw hole to adjust the position of the plug 9, and the pressure of the spring 7 is adjusted to adapt to filling of different mortar pressures;
