Abstract

The invention discloses a multi-nozzle airspray ball-service device for a volleyball smashing training device, comprising a ball-service device arranged on a base. One end of a ball outlet groove right opposite to a ball inlet and is fixed on a separator by a fixed frame at the upper end, and the other end surface of the ball outlet groove is opposite to a nozzle seat; both sides of the nozzle seat are symmetrically movably matched and connected with a pair of guide rods which are vertically arranged, and five nozzles are symmetrically distributed in a cross on the nozzle seat, a high-speed electromagnetic valve is arranged at the lower end of each nozzle, and a shooting cylinder is arranged above the nozzle seat; one side of an air storage tank fixed at the base of a box body is providedwith an air inlet for pipeline connection with an air supply hole of an air compressor, and the other side of the air storage tank is symmetrically provided with seven air outlets for respective pipeline connection with five rapid electromagnetic air valves and air cylinders. The invention has reasonable structural design, provides volleyballs running at high speeds for volleyball training and controls ball-service timing and rotational states of the volleyballs after being smashed by a trainer smashing baffle while the trainer smashing baffle is at any angle.

Description

technical field [0001] The invention relates to sports equipment for ball games, in particular to a multi-nozzle air-spray type ball server used for improving volleyball technology and used as a volleyball spiking training device. Background technique [0002] For the professional training of volleyball players, in addition to conventional techniques, technological means should also be introduced in a targeted manner to make up for the lack of manual training. For this reason, all kinds of equipment for assisting volleyball players arise at the historic moment. [0003] On November 15, 2006, the State Intellectual Property Office of the People's Republic of China disclosed a patent for invention—a simple training device for volleyball players (publication number is CN1861232A) applied by Hefei University of Technology. The feature of this simple training device for volleyball players is that a low-level serving platform and an adjustable serving stand are set; the bottom of...
