Football ejector

[0012] The following will be attached figure 1 , 2 To explain in detail the beneficial effects of the present invention, which aims to help reading

[0013] Readers have a better understanding of the essence of the present invention, but cannot limit the implementation and protection scope of the present invention.

[0014] The casing (8) is a hollow sector. The bottom surface of the inner cavity of the casing (8) is provided with a stepping motor (11). One side of the stepping motor (11) is connected to the second gear (10) and the second gear (10) through a shaft. ) The upper part is connected to gear one (9), one side of gear one (9) is fixedly connected to the rotating rod (7), the rotating rod (7) is connected to the inner wall of the housing (8) through several rolling bearings, and the upper end of the rotating rod (7) penetrates the shell On the upper surface of the body (8), the top end of the rotating rod (7) is fixedly connected to the ejection barrel (1), the ejection barrel (1) is a hollow cylinder, and a power switch is provided on one side of the outer wall of the ejection barrel (1) (14), power switch two (16), stepper motor controller one (13) and stepper motor controller two (15). The inner cavity of the ejection barrel (1) is provided with stepper motor one (from bottom to top). 13) Support plate (5), spring (4) and ejection plate (2). The ejection plate (2) is connected to the ejection barrel (1) through a number of rolling bearings, and the support plate (5) is fixed to the ejection barrel ( On the inner wall of 1), the ejection plate (2) is connected to the rotating shaft of the stepping motor one (6) through a wire rope (3), and the wire rope (3) penetrates the spring (4) and the support plate (5), the stepping Motor one (6), stepper motor controller one (13) and power switch one (14) are connected in sequence, said stepper motor two (11), stepper motor controller two (15) and power switch two (16) ) Connect sequentially.

[0015] A number of steel nails (12) are evenly distributed on the bottom surface of the shell (8).

[0016] The rotating rod (7) is coaxial with the projectile barrel (1).

[0017] The ejection barrel (1), the support plate (5) and the ejection plate (2) take the steel wire (3) as the central axis.

[0018] Before use, you need to insert the steel nail (12) into the grass, then turn on the power switch one (14) and power switch two (16) and place the football on the ejection board (2). When you need to adjust the ejection angle, pass Stepper motor controller two (15) controls the forward, reverse and rotation angle of stepper motor two (11) to rotate the rotating rod (7), so that the projectile barrel (1) rotates to the required angle, and then turn off the power switch One (14). At this time, the ejection plate (2) releases the restraint on the spring (4), so that the football is ejected from the ejection barrel (1); when the ejection force needs to be adjusted, the stepping motor controller one ( 13) To control the angle of forward, reverse and rotation of the stepping motor (6), so that the binding force of the ejection plate (2) to the spring (4) can be adjusted freely, so that the ejection force of the football can be changed.

[0019] The above-mentioned embodiments only describe the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, those of ordinary skill in the art have made various contributions to the technical solutions of the present invention. Variations and improvements should fall within the protection scope determined by the claims of the present invention.
