Abstract

The invention relates to a ball serving device, in particular to a table tennis ball serving device for physical education. The invention aims at providing the table tennis ball serving device for physical education, which is high in ball serving speed and uniform in force. In order to solve the technical problems, the following technical scheme is adopted: the table tennis ball serving device forphysical education provided by the invention comprises a bottom plate, support legs, a box, a placing block, a blanking hopper, a first baffle plate and the like, wherein the support legs are mountedin the middle of the top of the bottom plate, the box is mounted at the top ends of the support legs, the placing block is mounted on the left of the bottom in the box, the first baffle plate is mounted on the left of the top of the bottom plate, the first baffle plate is positioned on the left of the box, discharge holes are formed in the left of the box and the first baffle plate, and an intermittent blanking device is arranged at the top of the box. The ball serving device is used for serving a table tennis ball, through the intermittent blanking device, the table tennis ball is dischargedinto the box, and thus the effects that the ball serving speed is high and the force is uniform are achieved.
