Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail.
In conjunction with Fig. 1 to Fig. 5, the present invention includes the compositions such as three supporting mechanisms that can fold, walking disk, centre post, height azimuth rotation mechanism, ball case, air compressor, seat.Tennis discharger separates with adjusting the device launching angle, it is possible to speed, the direction of service and the drop point that guarantee is served a ball, and these can carry out selecting to set as required, and a series of actions is all automatically performed.In detailed description of the invention, centre post and ball case are main support sections, and height and orientation corner are to adopt dual-output motor lead agency to realize, and the power source that tennis is launched is air compressor.
Storage supporting seat 11 is threaded connection and is fixed in storage support cover for seat 10, storage is supported cover for seat 10 and is connected to one end of storage support bar 12 by bearing storage bearing pin 13, the other end of storage support bar 12 is received bearing pin 13 again by bearing and is connected on storage set 14, storage set 14 is threaded connection and is fixed on centre post 15, one end of clip 17 and clip support 5 is bolted and wraps centre post 15, can rotate around centre post 15, clip supports 5 other ends and is fixed on the cylinder barrel of seat lifting hydraulic cylinder 6, piston rod one end connecting chair road wheel 8 of seat lifting hydraulic cylinder 6, driven by seat movable motor 7, the other end of seat lifting hydraulic cylinder 6 is fixed on the seat 4 that can fold.nullInstallation height orientation, the upper end rotation angle mechanism of centre post 15，Its interior details figure is as shown in Figure 2，Centre post is connected axle 27 and is connected by bearing 28 with corner connecting rod 26，Corner connecting rod 26 is connected with gear wheel B24 by pitman pin 25，And the connected mode of corner connecting rod and pitman pin is to be articulated and connected，Pitman pin is fixing connection with gear wheel B，Little gear B 22 and gear shaft 20 interference are fixed in startup push button shaft 19，Start push button shaft 19 to press up and down pressing in spring assembly 23，Press spring assembly 23 and be arranged on enclosure interior，Pressing spring assembly 23 is common pressing buckle combinative structure，Such as pressing pen，The application is detailed description not，Gear shaft 21 is connected on an output shaft of dual-output motor 30 by shaft coupling，Dual-output motor 30 is screwed on dual-output motor bracing frame 29，Another output shaft of dual-output motor 30 connects height corner axle 31 by shaft coupling.
Height corner axle 31 is fixing with tennis case 1 side to be connected, the built-in netful ball 2 of tennis ball case 1, it it is the guiding channel of tennis transmitting below tennis case 1, passage has and feeds ball, prevent tennis 2 from out dropping afterwards from tennis ball case 1, baffle plate 35 can in baffle plate groove 33 pull, the pulling motion of baffle plate 35 realizes by the baffle plate cylinder 34 of side, and pneumatic tube 32 is connected by trachea 18 with air compressor 16.
After tennis discharger completes adjusting angle, baffle plate cylinder 34 pulls the baffle plate 35 in baffle plate groove 33, baffle plate 35 is made to extract out, tennis 2 falls into the guiding channel below tennis case 1, baffle plate cylinder 34 stretches out, baffle plate 35 slides in baffle plate groove 33, it is ensured that only one of which tennis falls into the guiding channel below tennis case 1 every time.Open the switch of air compressor 16, by air pipe 32, tennis 2 is blown out.
The radiation pattern of the present invention adopts pneumatic type, utilizes the thrust that gases at high pressure produce to launch tennis.Specific works process is as follows:
1, being placed in court by tennis discharger, start power supply, dual-output motor 30 works, and dual-output motor 30 drives the height direction that height corner axle 31 realizes tennis ball case 1 to rotate, thus changing the transmitting angle of tennis；
If 2 ball casees need azimuth rotation, startup push button shaft 19 pressed by needs, such gear A 20 engages with gear shaft 21, little gear B 22 engages with gear wheel B24, gear wheel B24 rotates around little gear B 22, gear wheel B24 drives corner connecting rod 26 to connect axle 27 around centre post by pitman pin 25 and rotates, housing 3 is connected with corner connecting rod, and move therewith, so make another axle of dual-output motor 30 achieve the tennis ball case all-direction rotation around centre post by the gear motion of two groups of gears.Tennis discharger is placed on arbitrary corner in court can make the tennis launched cover whole court.
3, after tennis discharger completes adjusting angle, baffle plate cylinder 34 pulls the baffle plate 35 in baffle plate groove 33, baffle plate 35 is made to extract out, tennis 2 falls into the guiding channel below tennis ball case 1, baffle plate cylinder 34 stretches out, baffle plate 35 slides in baffle plate groove 33, it is ensured that only one of which tennis falls into the guiding channel below tennis ball case 1 every time.Opening the switch of air compressor 16, blown out by tennis 2 by air pipe 32, the output pressure adjusting air compressor 16 can change the emission rate of tennis 2.
