The present embodiment will store up ball bucket 1, group ball machine structure 2 and conveying mechanism and merge into ball mechanism, and ball mechanism needs to store
Ball is simultaneously leaked ball to conveying mechanism, and conveying mechanism transfers out ball according to certain frequency.This set mechanism can analogize to hand
The structure of rifle, ball mechanism are equivalent to pistol cartridge clip, and the bullet of storage is supplied to bore, using being fired away after loading,
Once as soon as upper bullets loading percussion, cartridge clip are needed even if next bullet of offer.The storage ball bucket 1 of the present embodiment is by dialling ball
Mechanism 2 so that lose in time, be not in card ball make service interrupt；Ball mechanism is precisely controllable, realizes continuous table tennis
Continuous shooting.
Table tennis 26 is stored in ball bucket 1, by the leakage of hole 20 of losing of storage 1 bottom of ball bucket to conveying mechanism, dials ball electricity
Machine 9, which drives, dials the rotation of ball piece 10, so that the table tennis 26 stored up in ball bucket 1 be made to occur mutually to move, makes table tennis 26 from storage ball bucket 1
The hole 20 of losing of bottom is leaked to conveying mechanism, and card ball phenomenon is prevented, wherein 20 diameter of hole of losing of storage 1 bottom of ball bucket is
The plastics on new materials table tennis diameter of 50mm, D40+ are about 41mm, and 20 diameter of hole of losing is slightly larger than 26 diameter of table tennis.Storage ball bucket 1 is matched
Have and dial ball machine structure 2, prevents card ball.Conveying mechanism (is vertically lost pipeline 3 and level pipeline 4 of losing is in by 90 ° of interfaces
90 °), lose motor 6 and arc plectrum 7 form.Arc plectrum 7 rotates under the driving for motor 6 of losing according to the frequency of setting
To conveying table tennis 26, the dynamic process specifically conveyed is to open up behind conveying mechanism section referring to Fig. 7 to Figure 11, Fig. 7 to Figure 11
The motion state of the table tennis 26 shown, the arcuate shape of arc plectrum 7 make that storage ball can be given in rotary course with slot milling
The hole 20 of losing of bucket 1 is leaked down next table tennis 26 (such as Figure 11), moves in circles and multiple percussion can be realized.Due to ball mechanism
Conveying mechanism it is compact-sized, it is only necessary to 4 ball service robots can work normally, with existing large-size machine delivery wheel convey table tennis
Pang ball 26 is compared, small, and structure is simple.
At runtime, arc plectrum 7 has certain elasticity to the present embodiment, and due to inertia and gravity, table tennis 26 may
It is rolled out when arc plectrum 7 is not stirred, influences the function of normally serving a ball.So in the card ball connection of horizontal pipeline 4 of losing
Card ball device 27 is provided on block 25, card ball link block 25 there are 2 and is symmetrically set, and 2 card ball link blocks 25 are equipped with card
Ball device 27 constitutes card ball device 27 with card ball spring 30, card ball nut 29 and card ball screw 28, arrives Dacca ball device in table tennis 26
Behind 27 positions, since the effect of card ball spring 30 is so that card ball nut 29 gives certain resistance to table tennis 26, reduction is had more
The probability of ball.Only in the case where arc plectrum 7 is stirred, such as Fig. 9, arc plectrum 7 gives table tennis 26 certain thrust, table tennis
Pang ball 26 squeezes card ball nut 29, and card ball nut 29 squeezes card ball spring 30, and card ball spring 30 shrinks to make card ball nut 29
Xiang Kaqiu link block 25 moves, and table tennis 26 rolls to trigger mechanism (such as Figure 10).
It stores up and needs equipped with group ball machine structure 2 beside hole 20 of losing in ball bucket 1 to prevent card ball.When ball is more, need larger
Torque can just stir, the most fast frequency of conveying mechanism is about 50 revs/min, and storage ball bucket 1 needs bigger frequency to lose to conveying
Mechanism, dial ball motor 9 use ZGA20-130 decelerating motor, the decelerating motor operating voltage be 5V, reduction ratio 1:340, can
To provide larger torque, sound is lower, and when operating in 5V, revolving speed is 27 revs/min, connects strip by first shaft coupling 16
Dial ball piece 10, dial 9 every revolution of ball motor, dial ball piece 10 can dial ball twice, dial ball frequency can reach 54 beats/min, be higher than
Conveying mechanism highest frequency.
The motor 6 of losing of conveying mechanism uses N20 decelerating motor, and operating voltage 1.5V-6V turns when voltage is 3V
25 revs/min of scooter, when operating voltage reaches 6V, up to 50 revs/min, arc plectrum 7 is connected by second shaft coupling,
When arc plectrum 7 is single head, that is, arc plectrum 7 is c-type, 6 every revolution of motor of losing, arc plectrum 7 can be stirred once
Ball；When arc plectrum 7 is double headed arcuate plectrum, that is, arc plectrum 7 is S type, 6 every revolution of motor of losing, arc plectrum 7 can
To stir ball twice.
The present embodiment is arranged bracket institution 5, bracket institution 5 simultaneously with storage ball bucket 1, dial ball machine structure 2 and level and lose pipeline 4
It is fixed, make compact overall structure, in addition, conveying mechanism drives arc plectrum 7 to rotate using motor 6 of losing, to realize promotion
The effect of ball movement, it is whole small, need few table tennis 26 that service work can be completed.Wherein bracket institution 5 includes ten
After word support plate 11, cross-shaped fagging 11 and storage ball bucket 1 are fixed, keep overall structure more firm, in addition, cross-shaped fagging 11
Front-end and back-end are L-type, reserve fixation hole, can connect with support base.
The protection scope of the utility model includes but is not limited to embodiment of above, and the protection scope of the utility model is to weigh
