Abstract

The present invention relates to the technical field of volleyball devices, and is specifically a ball collection cart for volleyball training, comprising a box body. A cavity used for storing a volleyball is provided inside the box body, and a storage port is opened in the top of the box body, the storage port being in communication with the interior of the cavity. A separation panel is fixedly mounted in the interior of the box body, and a ball recovery inlet is opened at a central position of the separation panel. An annular telescoping piece is mounted at the edge of the ball recovery inlet, the inner diameter of the annular telescoping piece being smaller than the inner diameter of a volleyball. In the present invention, a separation panel is fixedly mounted in the interior of a box body, and a ball recovery inlet is opened at a central position of the separation panel. A volleyball on the ground can enter the interior of a cavity for storage by means of the ball recovery inlet, and when the volleyball enters the ball recovery inlet, pressure is exerted on the annular telescoping piece. Upon being subjected to pressure, the annular telescoping piece deforms, thus causing the ball recovery inlet to expand. The volleyball passes through the ball recovery inlet into the interior of the cavity, at which time the annular telescoping piece reverts and prevents the volleyball from being expelled from the ball recovery inlet.
