When the numerical value of setting is not achieved in interior compressed air, CPU closes second solenoid valve 31 by controller and then opens the first solenoid valve
36 carry out supplement compressed air for air accumulator 33, when the compressed air pressure value that air accumulator 33 is set is relatively low, or due to second
Solenoid valve 31 is continuous frequently to be opened, and when air accumulator 33 can not quickly supplement compressed air by external gas source, then CPU can pass through control
Device booster air pump 34 processed works, and compressed air is supplemented for air accumulator 33；It is living at this time since tennis training machine is in battery
Plug 18 is located at the rear ends of service pipe 11, and lock tongue 15 is then stuck in the top of piston 18, and compression spring 13 is in compressive state, in ball-storing box 1
Tennis by delivery pipe 2 enter service box body 3 after fall on first sensor 17, in the present embodiment first sensor 17 be pressure
First sensor 17 is transmitted to CPU by force snesor, collector by the signal data of the compression weight of tennis, and CPU is according to setting
Fixed program controls electromagnetic relay 16 by controller and starts, and electromagnetic relay 16 pulls lock tongue 15 to transport downwards by pull rod
Dynamic, when the card of lock tongue 15 does not live piston 18, compression spring 13 then pushes piston 18 to travel forward, and the front end of piston 18 sets that there are one as high
The release device of footed glass shape, the release device on piston 18 push tennis to enter cylinder 20 and be stuck on clamp spring 24, enter pending
Penetrate state；
When first sensor 17 is not transmitted to CPU by collector by the signal data of tennis compression weight, CPU roots
Second solenoid valve 31 is controlled by controller according to the program of setting to open, compressed air by tracheae and 12 moment of cylinder connector into
Enter cylinder 20, the high pressure draught that the high pressure gas in cylinder 20 is formed makes tennis be projected from service pipe 11；Simultaneously piston 18 by
Can be moved backward after pressure, when lock tongue 15 is crossed in the front end of piston 18, lock tongue 15 then bounces, compression spring 13 offseted piston 18 by
External force, push piston 18 travel forward, piston 18 is stuck on lock tongue 15, reenters battery；Since piston 18 pushes up
The side wall in portion is equipped with two seals ring 19, and the bottom sidewall of piston 18 is equipped with one of sealing ring 19, and sealing ring 19 is not only able to increase
The leakproofness for adding piston 18 and service pipe 11 increases the initial velocity of tennis, additionally it is possible to it is reciprocal in service pipe 11 to reduce piston 18
The speed of movement, reduces vibrations when damage and the percussion ball to part, and appropriate vibrations at this time can also play help and be in
Tennis in ball-storing box 1 smoothly enters the effect of delivery pipe 2.
Pattern two：Move Mode successively before and after tennis pick-up point：
Casing 47 is removed from service pipe 11, CPU controls the pressure of air accumulator 33 by controller according to the set procedure
Value makes tennis fall in the preceding point in court, midpoint and rear point, second sensing of the real-time capture setting of collector on air accumulator 33
The pressure value signal of air accumulator 33 is transmitted to CPU by the pressure value of device 32, and CPU controls the first solenoid valve 36 by controller
Open or close, when the compressed air in air accumulator 33 reach setting numerical value when, CPU pass through controller control the first solenoid valve
36 close, and when the compressed air in air accumulator 33 is less than setting numerical value, CPU controls the first solenoid valve 36 by controller and beats
It opens, the compressed air setting numerical value in air accumulator 33 changes at any time, when the numerical value of the compressed air setting in air accumulator 33 is higher,
Tennis falls the rear point in court, and when the compressed air numerical value in air accumulator 33 is moderate, tennis is fallen in the intermediate position points in court,
When compressed air numerical value in air accumulator 33 is relatively low, tennis is fallen in the falling sphere point before court, the ball speed of this pattern tennis
Have speed variation.When the pressure value of air accumulator 33 remains unchanged, CPU by controller control first motor 23 carry out it is positive or
It reversely rotates, the elevation-depression angle for service box body 3 to be raised and lowered equally is played and moved successively before and after controlling tennis pick-up point
Effect.
