When the basketball stand is used, the two transfer grooves 5 are communicated with the two through holes in the left-right direction, the step surface of the spiral drive plate 17 is in contact with the right catch post 15, the free end of the bottom plate 10 slides into the placing groove 9, and a plurality of basketballs are placed in the two placing frames 39 in an initial state;

basketball enters the transfer groove 5 through the connecting cylinder 38, the motor 16 is started, the motor 16 drives the spiral drive plate 17 to rotate anticlockwise, the spiral drive plate 17 pushes the right stop post 15 to rotate anticlockwise, the support shaft 14 further drives the rotary plate 4 to rotate anticlockwise, when the rotary plate 4 rotates until the transfer groove 5 is communicated with the two through holes in the front-back direction, the basketball in the connecting cylinder 38 enters the transfer groove 5 and rotates anticlockwise along with the rotary plate 4, when the spiral drive plate 17 rotates 180 degrees, the stepped surface of the spiral drive plate 17 is separated from the stop post 15, the two transfer grooves 5 are communicated with the two through holes in the left-right direction, and the basketball enters the placement groove 9; with the continuous rotation of the motor 16, the intermittent gear 18 starts to be meshed with the full gear 20, the full gear 20 drives the barrel 19 to rotate clockwise and pushes the guide post 22 to slide in the V-shaped groove 21 so as to enable the sliding column 6 to move downwards, the sliding column 6 drives the ejection column 8 to move downwards through the pressure spring 7, the ejection column 8 drives the ejection rod 37 and the Z-shaped rod 30 to move downwards, and the lower end of the ejection column 8 is in contact with a sphere;

if the gas in the sphere is full, which indicates that the gas filling amount in the sphere is qualified, the top pillar 8 does not move downwards any more, but the sliding column 6 continues to move downwards, at this time, the pressure spring 7 is compressed, because the middle pillar 27 is in large-pitch threaded connection with the sliding column 6, the middle pillar 27 rotates, the upper end of the middle pillar 27 is gradually inserted into the abdicating groove, meanwhile, the transmission gear 28 is meshed with the rack 29, the rack 29 drives the Z-shaped rod 30 to move towards the side away from the sliding column 6, the free end of the Z-shaped rod is gradually inserted into the spiral groove 26, along with the downward movement of the sliding column 6, the Z-shaped rod 30 moves downwards and drives the rotating pillar 23 to rotate and enable the coil spring to accumulate force, the rotating pillar 23 pulls the bottom plate 10 to move outwards through the first pull rope 24 and compress the spring, meanwhile, the rotating pillar 23 pulls the second baffle plate 13 to swing and extrude the second torsion spring through the second pull rope 25, when the guide pillar 22 slides to the bottom of the V-shaped groove 21, the bottom plate 10 is completely separated from the placing groove 9, a passage at one side of the screening groove 11 far away from the center of the rotary table 4 is opened by the second baffle 13, and qualified basketballs slide out of the passage at one side of the screening groove 11 far away from the rotary table 4 and enter the collecting frame 40 at the rear side;

meanwhile, as the lower end of the top column 8 loses support, the top column 8 moves downwards under the action of the pressure spring 7, the middle column 27 rotates reversely, the transmission gear 28 is meshed with the rack 29 to drive the Z-shaped rod 30 to move towards the direction of the sliding column 6, the free end of the lower side of the Z-shaped rod 30 is separated from the spiral groove 26, the rotating column 23 rotates reversely under the action of the coil spring, the first pull rope 24 and the second pull rope 25 become loose, the bottom plate 10 resets under the action of the spring, and the second baffle plate 13 resets under the action of the second torsion spring; along with the rotation of the cylinder 19, when the guide post 22 slides upwards from the bottom of the V-shaped groove 21, the sliding post 6 drives the top post 8 to move upwards and reset through the pressure spring 7;

if the gas in the sphere is not full, after the top pillar 8 is contacted with the surface of the sphere, along with the downward movement of the sliding pillar 6, the ejector rod 37 moves downward along with the top pillar 8 and the lower end of the top pillar 8 presses the surface of the sphere, pits gradually appear on the surface of the sphere, meanwhile, the ejector rod 37 pushes the lever to swing, the lever drives the sector gear 31 to be meshed with the transition gear, the rotating shaft drives the first baffle plate 12 to swing towards the center direction of the turntable 4 and press the first torsion spring through the rotation of the cross belt 35, meanwhile, the second belt pulley 34 pulls the bottom plate 10 to move through the third pull rope 36, the free end of the bottom plate 10 moves out of the placing groove 9, and the sphere with insufficient gas enters the collecting frame 40 on the front side through the screening groove 11; when the sliding column 6 drives the top column 8 to start to move upwards, the first baffle plate 12, the lever and the like reset under the action of the first torsion spring, and the bottom plate 10 resets under the action of the spring;

along with motor 16's the operation that lasts, realize a plurality of spheroidal screening, and gaseous sufficient spheroid is collected and is in the same place be convenient for the student and take, saves student's selection time and physical power, and gaseous not enough spheroid is collected and is in the same place, is convenient for concentrate and aerify, improves and aerifys efficiency, the management of being convenient for.

The invention is worth noting that after qualified basketballs enter the collecting frame 40 from the screening groove 11, the top post 8 moves downwards for a short distance under the action of the pressure spring 7, at the moment, the ejector rod 37 also moves downwards along with the top post 8, the lower end of the ejector rod 37 extrudes a lever downwards, the lever drives the sector gear 31 to be meshed with the transition gear, so that the bottom plate 10 moves and swings with the first baffle plate 12, but after the sliding post 6 drives the top post 8 to reset upwards, the bottom plate 10 and the first baffle plate 12 also restore to the initial state without influencing the next use.

In the invention, when the bottom plate 10 is pulled by the first pull rope 24 to move out of the placing groove 9, the third pull rope 36 is in a loose state, and when the bottom plate 10 is pulled by the third pull rope 36 to move out of the placing groove 9, the first pull rope 24 and the second pull rope 25 are both in a loose state, so that the normal operation of the invention is not influenced.

The invention has novel concept, ingenious structure, convenient operation and strong practicability, is provided with the intermittently rotating turntable, is convenient for transferring the ball to be checked below the top post, is provided with the top post and the top rod which move up and down after the transfer of the ball is finished, is convenient for checking and classifying according to the inflation amount of the ball, has high checking accuracy, selects and collects the balls which are full in inflation, is convenient for students to take, does not need to check and select proper basketballs one by one, saves the preparation time before the match, retains the physical strength, improves the match effect, collects the balls with insufficient gas together, is convenient for centralized management and inflation, and improves the inflation efficiency.

Therefore, the basketball inflation quantity inspection device provided by the invention can effectively solve the problem of low efficiency of basketball inflation quantity inspection, is simple in structure and operation and convenient to use, can realize the inspection of a plurality of basketball inflation quantities without manually selecting balls one by one, and is high in inspection efficiency.
