Said fan is installed in a side of spring hose, and the spring hose opposite side is provided with the dust mouth.
The hand-held dedusting service robot of this table tennis is through prolonging spring hose length, and traditional service robot head (ball mouth, friction pulley) part is dissociated out becomes hand-held.
Go out the placement change operation: the operator stands in contiguous net one side, holds hand holding handle (head) to opposite billiard table service, up and down, the wrist that swings, continuous conversion ball mouth direction, realization is sent to billiard table arbitrfary point, opposite with ball.
Go out ball velocity variations (strength variation) operation: be designed with the speed regulation bolt on the utility model hand holding handle; In the service process; At any time the governing speed regulation cock slides in speed regulation bolt chute, gives the control system of main frame through sending signal, and the control system is transferred to motor with signal; Thereby friction wheel from rotation speed is changed, thereby realize out ball velocity variations (strength variation).
Go out the ball change of frequency: be designed with frequency on the utility model hand holding handle and speed button and frequency reduction button, give the control system of main frame through sending signal, the control system controls out the ball frequency, controls button according to the training demand and can realize out the ball change of frequency.
Go out the ball rotation change: hold the utility model hand holding handle, make friction pulley be in directly over the time ball that sends be top spin; Hold hand holding handle along ball mouth self longitudinal axis Rotate 180 degree, make friction pulley be under the time ball that sends be chop; According to the training demand, rotate the hand holding handle of the utility model arbitrarily along ball mouth self longitudinal axis, can realize that comprehensive (360 degree) goes out the ball rotation change.
The beneficial effect of the utility model is: (1) can realize that drop point changes through wrist swinging; (2) realize that through controlling the speed regulation bolt speed (strength) changes; (3) speed and reduce button and realize out the ball change of frequency through controlling frequency; (4) realize rotation change through rotating head along ball mouth self longitudinal axis.Go out ball shortcoming with low uncertainty thereby overcome traditional service robot, better be the service of combat training demand.In addition, the wind-force that utilizes the high-power fan quick rotation to be produced is removed the dust on table tennis surface, the puzzlement of dust in the time of can solving table tenning ball servicing machine exercise multi-ball drill preferably.
Description of drawings
Fig. 1 is the overall schematic of the utility model;
Fig. 2 is the partial enlarged drawing of the utility model.
Among the figure: 1, ball mouth; 2, go out ball speed regulation bolt; 3, ball-collecting box; 4, friction pulley; 5, hand holding handle; 6, the spring flexible pipe of losing; 7, the pipe of losing; 8, main frame; 9, go out ball speed regulation bolt chute; 10, frequency reduces button; 11, speed regulation scale; 12, frequency speeds button; 13, dust mouth; 14, high-power fan; 15, air inlet.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Like Fig. 1, shown in Figure 2, a kind of table tennis is handed the dedusting service robot, and it comprises main frame 8 and ball-collecting box 3; Main frame 8 links to each other with the pipe 7 of losing; The pipe 7 of losing connects the spring flexible pipe 6 of losing, and the lose end of flexible pipe 6 of spring connects a hand holding handle 5, and hand holding handle 5 is provided with ball mouth 1, friction pulley 4 and motor; Said motor is electrically connected with main frame 8, and motor output shaft links to each other with friction pulley 4.
On hand holding handle 5, be designed with out ball speed regulation bolt chute 9, go out ball speed regulation bolt 2 and be located at out in the ball speed regulation bolt chute 9, go out on the ball speed regulation bolt chute 9 to be designed with speed regulation scale 11, go out ball speed regulation bolt 2 and also be electrically connected with main frame 8.
