Technical field
The utility model is related to table tennis auxiliary trainer tool, more particularly to a kind of table tennis practising device material.
Background technology
Currently, in table tennis ball kicking training, the training method of use is mainly：Practiced for ball by coach, with teammate
To practicing and practicing three kinds for ball using service robot, first two is affected for ball mode by the technical factor of people, if for gauge ball
Rule property is low, and training effect is then bad.And in the prior art, speed that can only be to service and direction are unable to the rotation side of control ball
To, that is to say, that sportsman can only carry out practice stroke to being not added with the ball turned, will certainly influence training effect.
The Chinese utility model patent of Publication No. CN203280998U discloses a kind of table tennis automatic kicking apparatus, packet
Ball serving device, ball feeding device and fixing device are included, the ball serving device includes service cylinder, rotating cylinder and air blower, and air blower is logical
It crosses connecting tube to connect with service cylinder, rotating cylinder is connected to service cylinder, and revolving part is equipped in the rotating cylinder, and revolving part passes through motor
Driving, the ball feeding device includes sliding block, and the sliding block is connect with toggle, and the ball hole of ball feeding device passes through release
Pipe is connected with ball-collecter, and the ball mouth of ball feeding device is aligned with rotating cylinder.It can make the ball rotation sent out, and rotation can be controlled
Direction and speed, helping sportsman to practice spiral should connect.
There are following defects for said program：It is only capable of the left-handed and dextrorotation of control table tennis, top spin and backspin cannot be generated
Ball.
Utility model content
The purpose of this utility model is to provide a kind of table tennis practising device materials, can send out the table tennis of various rotation directions.
To achieve the goals above, the base case of the utility model is：A kind of table tennis practising device material, including feed ball
Cylinder, the lower end for feeding ball cylinder are communicated with vertical release pipe, further include horizontally disposed service cylinder, and serving a ball, cylinder is vertical with release pipe to be connected
It is logical, further include that pedestal, air blower, motor and one end in the bend pipe that is connected to of 1/4 circular arc, the connection bend pipe are rotatably connected on drum
It is connected on the air outlet tube mouth of wind turbine and with discharge pipe, is connected to the end alignment of the other end and service cylinder of bend pipe, the output of motor
Axis is coaxial with the discharge pipe of air blower and is fixedly connected with bend pipe is connected to, and motor and service cylinder are each attached on pedestal, the hair
The side of the separate connection bend pipe of ball cylinder is set there are four straight slot, and four straight slots are evenly distributed with along the circumferential direction of service cylinders, and one is respectively provided at straight slot
A rotating mechanism, the rotating mechanism include two belt pulleys, the belt being wound on two belt pulleys and two connecting shafts, institute
It is axial arranged along service cylinder to state belt, belt is concordant with service cylinder inner wall, and two belt pulleys are rotatably connected in connecting shaft respectively
And external driving mechanism, connecting shaft are fixed on service cylinder.
The technical principle of this base case is：
The caliber of release pipe and service cylinder is only capable of accommodating a table tennis, therefore a row table tennis is housed in release pipe, hair
Only there are one tablees tennis for the infall of ball cylinder and release pipe；One end of connection bend pipe is rotatably connected on the air outlet tube mouth of air blower
On, connection bend pipe under the drive of motor to be rotated centered on air outlet tube mouth, to make connection bend pipe at intervals with service cylinder
End alignment, when connection bend pipe be directed at service cylinder, the discharge pipe of air blower by connection bend pipe to blowing in cylinder of serving a ball, from
And the table tennis of infall is blown out from service cylinder.
When table tennis passes through rotating mechanism, since belt is concordant with service cylinder inner wall, belt movement, therefore belt is to table tennis
Ball have make its rotate active force, to make table tennis generate rotation under the action of belt, when table tennis from serve a ball cylinder end
When mouth is launched, rotation has just been taken.
This base case has the beneficial effect that：
1, four rotating mechanisms in this programme are located at the upper and lower, left and right of service cylinder, generate top spin, backspin respectively
Ball, hook and Slice.
2 while when opening the rotating mechanism of two non-relative position relations, for example, it is upper and left, it is lower and right, moreover it is possible to generate more
The screw of more rotation directions.
3, by adjusting the rotary speed of belt, the rotary speed of screw can be controlled.
Further, the connectivity part of the service cylinder and release pipe is equipped with gear door, and gear door hinge is connected on service cylinder close to air blower
One end.
When the discharge pipe of air blower is by being connected to bend pipe to blowing in service cylinder, gear door is first subjected to wind action power and quilt
That blows starts, and blocks release pipe after starting, and wind is avoided to be blown upwards from release pipe, and after connection bend pipe leaves service cylinder, gear door exists
Gravity whereabouts postbacks in ball cylinder, and next table tennis enters service cylinder.
Further, the driving mechanism is servo motor.
Servo motor can change direction of rotation, to generate the screw of different rotation directions.
Further, the port 2-5mm of the straight slot and rotating mechanism distance service cylinder far from air blower side.
Table tennis comes out from port of the service cylinder far from air blower side, and the outlet of rotating mechanism distance is closer, table tennis
Rotation is more apparent.
Further, the belt is equipped with the rough coatings for increasing friction.
Increase active force of the belt to table tennis, ensures that it generates rotation.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model embodiment.
Specific implementation mode
It is further described below by specific implementation mode：
Reference numeral in Figure of description includes：Feed ball cylinder 1, release pipe 2, service cylinder 3, pedestal 4, air blower 5, outlet air
