The upper side of the collecting box 15 is fixedly provided with a supporting bar 19, the right side of the supporting bar 19 is fixedly provided with a connecting block 20, the left side of the connecting block 20 is fixedly provided with a collecting pipe 21, the upper half section of the collecting pipe 21 is a bent pipe bent rightwards, the right end of the collecting pipe 21 is fixedly connected with a funnel-shaped material guiding net 22, the right end of the funnel-shaped material guiding net 22 is fixedly connected with a blanking net 25, the lower end of the blanking net 25 is arranged in the U-shaped net 5, the table tennis is flown upwards through the table tennis, when a user does not catch the table tennis in the air, or when the user does not need the table tennis, the table tennis flies out, the table tennis enters the collecting box 15, so that it can move to the right along the bend of the upper half of the collecting pipe 21 and enter the funnel-shaped material guiding net 22, so that it can enter the blanking net 25, so as to enter the U-shaped net 5 along the blanking net 25 for collection, thereby preventing the table tennis balls from scattering on the ground caused by nobody receiving the table tennis balls.

The upper end fixed mounting of support bar 19 has spliced pole 23, the upper end fixed mounting of spliced pole 23 has support ring 24, the inner wall of support ring 24 and the guide net 22 outside fixed connection that leaks hopper-shaped, the right inner wall fixed mounting of U-shaped net 5 has guide ring 4, guide ring 4 is fixed cup joints on unloading net 25, through support ring 24, can support the guide net 22 that leaks hopper-shaped, can keep leaking hopper-shaped like this and net 22 and present the state of opening, thereby make things convenient for the table tennis to pass through, can help the table tennis to get into in the U-shaped net 5 through guide ring 4 simultaneously, thereby improve the practicality of device.

Hopper 6 includes trapezoidal strip a61 down, trapezoidal strip a 61's left side fixed mounting has pick-up plate 62, equal fixed mounting in both sides has baffle 64 around trapezoidal strip a61, the front fixed mounting of baffle 64 at back has trapezoidal strip b65, trapezoidal strip b 65's front side and preceding baffle 64 rear side fixed connection, trapezoidal strip a 61's left side fixed mounting has collection box 63, income ball mouth 66 has been seted up to the upside of collection box 63, move left along trapezoidal strip a61 through the table tennis, will bounce when the table tennis falls into pick-up plate 62, thereby good table tennis can bounce smoothly and fall into trapezoidal strip b65 top and slide and fall into collection box 15 in, and the table tennis that loses gas leakage elasticity, will get into in collection box 63 through going into ball mouth 66, thereby will leak gas and lose elastic table tennis and collect, just so can separate the screening with bad ball good ball.

In use, the first step: when the collecting net 3 is impacted by the high-speed table tennis, the table tennis is stopped by the collecting net 3, so that the high-speed table tennis can be intercepted, the table tennis is stopped and moved downwards along the collecting net 3 to enter the U-shaped net 5 for collection, the table tennis enters the U-shaped net 5 and then enters the discharging hopper 6 along the U-shaped net 5, so that the table tennis enters the collecting box 15 through the feeding port 11 along the discharging hopper 6 and then enters between the two rotating plates 14, meanwhile, when the collecting net 3 is impacted by the high-speed table tennis, the driving rope 2 is driven to move rightwards to pull, so that the movable ball 7 is driven to swing, the movable ball 7 swings to impact the trigger plate 27, so that the trigger plate 27 is driven to move leftwards, so that the connecting strip 26 can be driven to rotate anticlockwise along the flywheel 16, so that the rotating column 12 is driven to rotate anticlockwise through the flywheel 16, just so can drive rotor plate 14 along the column spinner 12 anticlockwise rotation, thereby it removes to drive the table tennis that gets into between the rotor plate 14, when moving the inclined plane of trapezoidal piece 28 when rotor plate 14 is rotatory, will drive trapezoidal piece 28 downstream, can drive pressure spring 29 deformation downwards simultaneously, when rotor plate 14 separates with trapezoidal piece 28, pressure spring 29 will kick-back and drive trapezoidal piece 28 rapid rebound, thereby just can drive the table tennis rebound that moves to trapezoidal piece 28 top, just so can fly out collecting box 15 through logical groove 17, thereby the user of service can catch the table tennis from half empty, can make things convenient for the user of service to take the ball when can help the user of service to collect scattered table tennis like this.

The second step is that: when the trigger plate 27 moves leftwards, the soft plate 32 is driven to deform rightwards, so that the rebound of the soft plate 32 can drive the trigger plate 27 to return to the original position, meanwhile, the force for moving rightwards can be exerted on the trigger plate 27, the movable ball 7 can be impacted, the movable ball can swing more violently, the trigger effect of the device is improved, and the using effect of the device can be improved.

The third step: when the rotating plate 14 moves, the supporting rod 8 can be driven to move, so that the rotating rod 9 can be driven to move, when the rotating plate 14 moves to the inclined surface of the trapezoidal block 28, the rotating rod 9 can be in contact with the trapezoidal block 28, so that the rotating rod moves in a rotating manner, the friction force between the rotating plate 14 and the trapezoidal block 28 can be reduced, and the sensitivity of the device can be improved.

The fourth step: by the upward flying of the table tennis balls, when a user does not catch the table tennis balls in the air or the table tennis balls fly out when the user does not need the table tennis balls, the table tennis balls can enter the collecting box 15, and can move rightwards along the bent part of the upper half section of the collecting pipe 21, and then enter the funnel-shaped material guiding net 22, and then enter the discharging net 25, and then enter the U-shaped net 5 along the discharging net 25 to be collected, so that the table tennis balls can be prevented from scattering on the field due to no reception of people.

The fifth step: through the support ring 24, can support the guide net 22 that leaks hopper-shaped, can keep leaking hopper-shaped guide net 22 like this and present open state to make things convenient for the table tennis to pass through, can help the table tennis to get into in the U-shaped net 5 through guide ring 4 simultaneously, thereby improve the practicality of device.

And a sixth step: move left along trapezoidal strip a61 through the table tennis, will bounce when the table tennis falls into pick-up plate 62 to good table tennis can bounce smoothly and fall into trapezoidal strip b65 top and landing to collection box 15 in again, and gas leakage loses elastic table tennis, will get into through going into ball mouth 66 and collect in the box 63, thereby loses elastic table tennis with gas leakage and collects, just so can separate the screening with good ball and bad ball.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
