Backboard and hoop move up and down, and then hoop back-and-forth motion moves up and down simultaneously, and trainer can start to carry out fixed point shooting.
After the completion of trainer's training, driving motor can be closed.
When trainer is when carrying out fixed point shooting, the basketball for not encountering backboard is fallen in collection frame, in collection frame
Basketball is fallen to out in bulb, and the basketball in bulb is fallen in hemispherical shell body by through-hole out, the basket in hemispherical shell body
Ball is fallen in cabinet by ball hole.When there is suitable basketball in cabinet, trainer, that is, openable cover board passes through second
Opening takes out the intracorporal basketball of case, after the intracorporal basketball of case all takes out, can close cover board.In this way, can avoid missing
Basketball fall to around be difficult to collect.
When the basketball in hemispherical shell body is fallen in cabinet by ball hole, basketball contacts all rollings with inclined plate in case
Internal right part, when there is suitable basketball in cabinet, trainer can step on pedal and move down, and pedal moves down drive
Baffle moves down, spring-compressed, and baffle, which moves down, does not block ball mouth, and because of the effect of inclined plate, basketball passes through ball mouth
It falls to outside cabinet, the basketball that trainer can will fall off out is collected.After the intracorporal basketball of case is all fallen out, i.e.,
Pedal can be unclamped, because of the effect of spring, baffle moves up recovery to original position.In this way, receipts of the more convenient trainer to basketball
Collection.
Compared with prior art, the present invention has the advantage that the present invention is by starting driving motor, before can making hoop
After move up and down while move, improve the difficulty of trainer's shooting, and then improve training effect, by collection device,
The basketball that do not knock down can be then collected, so constantly run without trainer and pick up basketball, it is convenient and efficient, pass through
The effect of inclined plate and ball mouth is more convenient trainer to basketball as long as trainer steps on pedal and basketball can be made to fall out
Collection.
