Abstract
The invention discloses a table tennis ball picker and a working method thereof. The ball picker comprises a vacuum generator, a connecting pipe, a three-way pipe, a baffle, a two-way pipe, a ball collection box, a delivery pipe and a ball inlet pipe, wherein the vacuum generator is connected with one port of the three-way pipe through the connecting pipe; the other two ports of the three-way pipe are respectively connected with the two-way pipe and the delivery pipe; the delivery pipe is connected with the ball inlet pipe; the other port of the two-way pipe is connected with the ball collection box; and the baffle is installed in the three-way pipe. By utilizing related fundamental principles in aerodynamics, balls are picked in a vacuum adsorption mode, and the air drives the table tennis balls into the inlet pipe of the picker, so that the friction between the balls and the picker is small and the balls are quickly picked into the ball collection box. The invention has the advantages of simple structure, high efficiency, convenient operation and labor saving, and does not affect the service life of the table tennis balls since the air and the balls do not generate friction.
Description
Technical field
The present invention relates to a kind of sports auxiliary equipment, particularly a kind of pingpong ball picker and method of work thereof.
Background technology
Table tennis is a kind of sports that liked by people, and people frequently bend over to pick up the problem that the table tennis that drops on the ground is interrupted exercise thereby run into through regular meeting in the process that exercise is played table tennis.For this reason, people find out the method for the many tablees tennis of deposit, earlier no matter be scattered in ground ball, wait the ball of all deposits to use up after, concentrate again and pick up ball.Make exercise reduce many interruptions like this, can not reduce the number of times of frequently bending over to pick up ball, still have the problem that wastes time and energy, wasted valuable practice periods.In order to address this problem, people have invented many kinds of pingpong ball pickers in succession, for example tubular type ball picker, bucket formula ball picker, roller type ball picker and automatically picking up balls machine etc.They have improved the efficient of picking up ball to a certain extent, have reduced the labour intensity that picks up ball.But they generally can not reach nimble but also efficient higher requirement not only simple in structure.In addition, they adopt some basic principles of tribology at large, thereby exist ball picker tool and table tennis friction too much to reduce the table tennis problem in service life.
Summary of the invention
Be to solve the problems referred to above that prior art exists, the present invention to design a kind of simple in structure, pick up ball efficient height, and do not influence the pingpong ball picker and the method for work thereof in table tennis life-span.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of pingpong ball picker, comprise vacuum generator, tube connector, three-way pipe, baffle plate, two siphunculus, ball collection box, carrier pipe and goal tube, described vacuum generator is connected with a port of three-way pipe by tube connector, two ports in addition of three-way pipe are connected with carrier pipe with two siphunculus respectively, carrier pipe links to each other with goal tube, and the another port of two siphunculus links to each other with ball collection box; Baffle plate also is installed in the described three-way pipe.
The inner surface of baffle plate of the present invention and outer surface all are part annular surfaces, and the small end ring cross section of inner surface and big end ring cross section are circular arc, are having a rectangle square hole near big end place centering.
Plate washer of the present invention is fixed on the inboard of three-way pipe by gluing or snap fit, the goal end inner surface of its inner surface and three-way pipe with go out the pommel inner surface and form fairing and be connected.
A kind of method of work of pingpong ball picker may further comprise the steps:
A, at first open switch on the vacuum generator, hand-held then vacuum generator handle makes the closely table tennis on the face of the goal mouth of pipe;
B, table tennis are under action of air pressure, be inhaled into goal tube, arrive three-way pipe by carrier pipe rapidly, in three-way pipe, run into baffle plate, table tennis enters endless track, in this space, air pressure difference is reduced to zero gradually before and after the table tennis, and a table tennis gravitate and tangentially fly out at the effect lower edge of velocity inertial endless track is fallen in the ball collection box of vacuum;
C, when the table tennis in the ball collection box reaches the number of the table tennis that picks up or trunkful, close the vacuum generator switch, open the lower end door of ball collection box, all tablees tennis in the ball collection box can lean on deadweight to flow out automatically.
Vacuum in the ball collection box of the present invention is 90000-96000Pa.
Compared with prior art, the present invention has following beneficial effect:
1, because assembly of the present invention is less, wherein mostly be plastic pipe, simple in structure, consolidation convenience is convenient to put and carry.
2, existing pingpong ball picker picks up a table tennis needs the above time in 1 second, and the present invention detects through overtesting, under the normal condition in table tennis exercise place, picks up table tennis about 0.2～0.5 second, ten ball efficient has been had significantly improve.
3, the present invention proposes a kind of aerodynamic relevant basic principle of utilizing, pick up ball, allow the air push table tennis enter the inlet tube of ball picker, make the friction of ball and ball picker tool less, promptly ball is picked up in the ball collection box by the mode of vacuum suction.Because air and table tennis do not produce friction, do not influence table tennis service life.
4, because the present invention as long as with the goal tube port near table tennis 20mm about, table tennis will enter goal tube automatically, need not apply any other active force, and is easy to operate.
