[0020] Please refer to Figures 1-4 , the present utility model provides a basketball directional throwing device, including a ball outlet box 1. A base 2 is provided at the bottom of the ball outlet box 1. A moving seat 3 is provided at the bottom of the base 2. The ball outlet box 1 and the base 2 are rotatably connected. Two rod grooves 8 are provided on the top surface of the base 2. A threaded rod 9 is rotatably connected inside the rod groove 8. A threaded sleeve 13 is threadedly connected to the outer peripheral surface of the threaded rod 9. The top of the threaded sleeve 13 is hinged to a support rod 14. The top of the support rod 14 is hinged to the bottom surface of the ball outlet box 1. A first motor 12 is fixed on the surface of one side of the base 2. One side of the ventilation threaded rod 9 passes through the base 2 and is fixed to the output end of the first motor 12. A rotating shaft 18 is rotatably connected to the middle position of the top surface of the moving seat 3. The top of the rotating shaft 18 is fixed to the bottom surface of the base 2. A second motor 15 is fixed on the bottom surface of the moving seat 3. The output end of the second motor 15 passes through the moving seat 3 and extends to a position close to the rotating shaft 18. A first gear 19 is fixedly sleeved on the outer peripheral surface of the rotating shaft 18. A second gear 20 is fixedly sleeved on the output end of the second motor 15. The first gear 19 and the second gear 20 are meshed with each other. By starting the first motor 12, the ball outlet box 1 can change the angle in the vertical direction. By starting the second motor 15, the ball outlet box 1 can change the angle in the horizontal direction, so that the angle direction of the basketball thrown at the ball bin 4 can be adjusted, thereby improving the applicable range of the device.
[0021] Furthermore, as in Figure 1 , Figure 2 and Figure 3As shown in the figure, it is worth specifically explaining that the other sides of the two threaded rods 9 pass through the base 2 and extend to the other side of the base 2. A first pulley 10 is fixedly sleeved on the outer peripheral surface of the threaded rod 9 at the position where it extends out of the base 2. A connecting belt 11 is arranged at the middle position between the two first pulleys 10. When one of the threaded rods 9 rotates to drive one of the first pulleys 10 to rotate, the other first pulley 10 can be driven to rotate the threaded rod 9 under the connection of the connecting belt 11.
[0022] Further, as Figure 4 shown in the figure, it is worth specifically explaining that a guide groove 16 is opened on the top surface of the moving seat 3 at the outer position of the first gear 19. Two symmetrically distributed guide blocks 17 are slidably inserted into the guide groove 16. The top of the guide block 17 is fixed to the bottom surface of the base 2. Since the guide block 17 can only slide along the inner cavity track of the guide groove 16, it can limit the movement track of the ball outlet box 1, making the movement state of the ball outlet box 1 more stable when it rotates.
[0023] Further, as Figure 4 shown in the figure, it is worth specifically explaining that a fixing ring 21 is fixed on the top surface of the moving seat 3 at the position outside the guide groove 16. A plurality of positioning holes 22 are formed through the surface of the fixing ring 21 in an equidistant and circumferential distribution. A second hydraulic cylinder 23 is fixed on the surface of one side of the guide block 17. The output end of the second hydraulic cylinder 23 passes through the adjacent guide block 17 and extends into the adjacent positioning hole 22. When the ball outlet box 1 rotates to a corresponding angle, by starting the second hydraulic cylinder 23, its output end extends into the adjacent positioning hole 22, so that the state of the ball outlet box 1 can be limited under the abutting action between the output end of the second hydraulic cylinder 23 and the inner cavity of the positioning hole 22.
[0024] Further, as Figure 2 shown in the figure, it is worth specifically explaining that a ball bin 4 is opened inside the ball outlet box 1. A first hydraulic cylinder 5 is fixed on the surface of one side of the ball outlet box 1. A push plate 6 is slidably inserted into the ball bin 4. The output end of the first hydraulic cylinder 5 passes through the ball outlet box 1 and is fixed to the surface of the push plate 6. When the basketball enters the inner cavity of the ball bin 4, by starting the first hydraulic cylinder 5, the push plate 6 can move along the inner cavity of the ball bin 4, and the basketball is thrown out from the ball bin 4 under the thrust applied by the push plate 6.
[0025] This solution has the following working process: During actual use, after the basketball enters the inner cavity of the ball bin 4, by starting the first hydraulic cylinder 5, the push plate 6 can move along the inner cavity of the ball bin 4, so that the basketball is thrown out from the ball bin 4 under the thrust applied by the push plate 6. When it is necessary to adjust the throwing angle at the ball outlet box 1 along the vertical direction, by starting the first motor 12, one of the threaded rods 9 can be rotated. When one of the threaded rods 9 rotates, it drives one of the first belt pulleys 10 to rotate. Then, under the connection of the connecting belt 11, the other first belt pulley 10 drives the threaded rod 9 to rotate. Since the inner cavity of the rod groove 8 can limit the threaded sleeve 13 by resistance, the threaded sleeve 13 can move horizontally under the cooperation between the internal thread structure on the inner wall of the threaded sleeve 13 and the external thread structure on the outer peripheral surface of the threaded rod 9, so that the support rod 14 can change its angle, and then the ball outlet box 1 can change its angle along the vertical direction. Thus, the angle of the basketball thrown from the ball outlet box 1 can be adjusted along the vertical direction. When it is necessary to adjust the throwing angle of the ball outlet box 1 along the horizontal direction, by starting the second motor 15, the second gear 20 can be rotated. Then, under the meshing action between the second gear 20 and the first gear 19, the rotating shaft 18 can drive the ball outlet box 1 to change its angle along the horizontal direction. And by starting the second hydraulic cylinder 23, its output end extends into the adjacent positioning hole 22, so that the state of the ball outlet box 1 can be limited under the resistance between the output end of the second hydraulic cylinder 23 and the inner cavity of the positioning hole 22. Thus, the basketball can be thrown at multiple angles.
[0026] According to the above working process, it can be seen that by starting the first motor 12, the ball outlet box 1 can change its angle along the vertical direction, and by starting the second motor 15, the ball outlet box 1 can change its angle along the horizontal direction. Thus, the angle direction of the basketball thrown from the ball bin 4 can be adjusted, which improves the applicable range of the device and its practicality. When the ball outlet box 1 changes its angle along the horizontal direction, the output end of the second hydraulic cylinder 23 extends into the adjacent positioning hole 22, so that the ball outlet box 1 can be limited under the resistance between the output end of the second hydraulic cylinder 23 and the positioning hole 22, making the state of the ball outlet box 1 more stable after the horizontal angle adjustment, and further improving the practicality of the device.
[0027] Furthermore, as Figure 2 shown, it is specifically worth noting that a ball guide seat 7 is fixed on the top of the ball outlet box 1. The inside of the ball guide seat 7 is connected to the ball bin 4, and the inner cavity surface of the ball guide seat 7 is arc-shaped. Due to the shape of the ball guide seat 7, it is convenient for the basketball to enter the inner cavity of the ball bin 4 after entering the ball guide seat 7, thus improving the convenience of using the device.
[0028] In summary: by starting the first motor 12, the angle of the ball outlet box 1 can change in the vertical direction, and by starting the second motor 15, the angle of the ball outlet box 1 can change in the horizontal direction, so that the angle direction of the basketball thrown out from the ball bin 4 can be adjusted, thereby improving the scope of application of the device, thereby improving the practicality of the device, and by allowing the output end of the second hydraulic cylinder 23 to extend to the inside of the adjacent positioning hole 22 when the angle of the ball outlet box 1 changes in the horizontal direction, the ball outlet box 1 can be limited under the interference between the output end of the second hydraulic cylinder 23 and the positioning hole 22, so that the state of the ball outlet box 1 after the angle adjustment in the horizontal direction is more stable, thereby further improving the practicality of the device, and through the shape setting of the ball guide seat 7, it is convenient for the basketball to enter the inner cavity of the ball bin 4 after entering the ball guide seat 7, thereby improving the convenience of use of the device.
[0029] The first hydraulic cylinder 5, the first motor 12, the second motor 15 and the second hydraulic cylinder 23 can be purchased on the market. The first hydraulic cylinder 5, the first motor 12, the second motor 15 and the second hydraulic cylinder 23 are equipped with power supplies, which are mature technologies in this field and have been fully disclosed, so they are not repeated in the specification.
