Description

Badminton Automatic Serving Machine

technical field

The invention belongs to the technical field of sports equipment for badminton teaching and training, and in particular relates to an automatic badminton serving machine.

Background technique

Badminton is one of the advantageous sports in our country, and it is loved by people of different ages. When performing badminton practice, it is usually necessary to feed the shuttlecock to the position of the practitioner by hitting or throwing by a coach or a skilled person familiar with badminton. Because the height, position and parabola of artificially hitting and throwing the ball will be different, it is not conducive to improving the skill of the ball learner and/or achieving the desired training purpose, and even the situation of getting twice the result with half the effort occurs. Using the badminton machine to serve the ball can make up for this deficiency to a certain extent, and can also significantly reduce the teaching intensity of the trainers and coaches, and even carry out self-training and sports without coaches and skilled persons, that is, Single batting practice.

In the published Chinese patent literature, it can be seen that all the technical information about the automatic shuttlecock serving machine, such as the utility model patent authorization announcement number CN203803081U, recommends "a kind of badminton serving device for teaching", and the invention patent application publication number provides "a kind of shuttlecock serving device".

The motor that rotates the support bar, the motor that drives the gripper to rotate, the motor that drives the gripped badminton racket to move, the motor that drives the carrying plate to move, and the motor that drives the turntable to move, so the number of power mechanisms is large. It is not conducive to saving electric energy and is not conducive to low cost, and it is difficult to manufacture and assemble; secondly, because there are many transmission links, when any link is out of coordination, it will cause the failure of serving; The falling process of the shuttlecock is divided into two steps or two stages. First, the head of the shuttlecock is protruded from the bottom of the cylinder by the weight of the shuttlecock, and then the shuttlecock is clamped (taken out) by the gripper with a relatively complicated structure, so that the shuttlecock Once there is a time difference between the timing of free (automatic) falling by virtue of its gravity and the timing of gripping by the gripper, it will cause gripping failure. In particular, due to the particularity of the shape of the shuttlecock, if there is no external force, the feather of the shuttlecock is in contact with the wall of the cylinder, so it is usually difficult to fall out of the cylinder under its own weight. The diameter (inner diameter) of the barrel cavity is appropriately enlarged so that the feather of the shuttlecock and the barrel wall of the shuttlecock are in a state of contact and non-contact. The two shuttlecocks fell out of the cavity of the barrel together in an uncontrolled manner.

Under the work of the driving motor 22 and the motor 42, for example, when the motor 42 is in the forward rotation (clockwise rotation) state, the aforementioned ball-by-ball disc 61 is displaced downward on the screw mandrel 5, and the ball-by-ball disc 61 is displaced downward during the downward displacement. The rod 62 drops the shuttlecock 7 loaded in the ball storage cavity 321 through the ball drop hole 312 of the rotary disc, and the dropped shuttlecock 7 is sent out by the badminton racket 8 .

In the above process, every time the racket driving shaft 26 rotates 360°, the gear rotary plate 31 rotates 90° (taking four ball storage cylinders as an example), the ball carrying mechanism 3 outputs a shuttlecock 7, and the badminton racket 8 hits the ball and serves once . If the number of one group of ball storage tubes 32 is three, then the racket drive shaft 26 rotates 360° every time, the gear rotating disk 31 just rotates 120°, the ball carrying mechanism 3 outputs a shuttlecock 7, the badminton racket 8 completes a serve, and the rest analogy.

When the shuttlecocks 7 in one group of ball storage tubes 32 are used up, the motor 42 reverses, and the gear rotary plate 31 moves upwards to the top, then the motor 42 stops working, and the operator removes one group of ball storage tubes 32 from the ball storage tube Pull out on the plug sleeve 313, shuttlecock 7 is packed into, return on the ball storage tube plug sleeve 313 again.
