Description

Technical Field

[0001] The present invention relates to the field of sports equipment, and particularly to a tennis picking device. Background Art

[0002] During tennis training and matches, a large number of tennis balls are consumed. A large number of tennis balls not only affect the game but also pose a safety hazard to people. It is necessary to collect a large number of tennis balls in a timely manner and put them into the game and training. Traditional tennis collection devices can only collect tennis balls and cannot immediately put them into use. It is necessary to transfer the tennis balls to the hands of the user. A device is needed to solve the above problems. Summary of the Invention

[0003] [[ID=|13]]In view of the above deficiencies in the prior art, the present invention provides a tennis picking device that can collect tennis balls and immediately put them into use.

[0004] The object of the present invention is achieved through the following technical solutions:

[0005] A tennis picking device includes a machine base. On both sides of the machine base, a rotating rod is rotatably connected. The rotating rod drives a triangular rod to swing through a first connecting rod. The triangular rod drives a flipping rod to flip through a second connecting rod. The flipping rod flips the tennis balls collected by a spiral shaft into a ball hopper above the machine base. On both sides of the machine base, there is a side plate respectively. On the outer side of each side plate, a first motor is fixedly connected to a motor plate. The output shaft of the first motor is fixedly connected to a first wheel. The outer side of the first wheel is rotatably connected to a belt. The other side of the belt is rotatably connected to a second wheel. The second wheel is fixedly connected to a first rotating shaft on one side of the rotating rod. The first rotating shaft rotates in a side plate hole on the upper side of the side plate. A second rotating shaft on the other side of the rotating rod is hinged to a first connecting rod. The other side of the first connecting rod is hinged to a first hole in the middle of the triangular rod. A third hole in one side of the triangular rod is hinged to a first shaft on the side of the side plate. A second hole in the other side of the triangular rod is hinged to a first hole in the upper part of the flipping rod. A second hole below the first hole of the flipping rod is hinged to a second shaft on one side of the first shaft of the side plate.

[0006] On both sides of the machine base, there are two symmetric side grooves. At the inner side of the front end of each side groove, there is a ball outlet groove. Inside each side groove, a blocking block is slidably connected. The rear side of each blocking block and the rear side of the side groove are fixedly connected by a spring.

[0007] Inside the flipping rod, there is a rotating arm. In the middle of the rotating arm, there is a rotating arm hole through which the tennis ball passes. At the inner side of the end of the rotating arm hole, there is a goal hole. When the flipping rod rotates to the lowest position, the rotating arm enters the corresponding side groove. The rear side of the rotating arm squeezes the blocking block backward. The rotating arm hole is aligned with the corresponding ball outlet groove. When the flipping rod rotates to the highest position, the rotating arm leaves the side groove. The blocking block blocks the corresponding ball outlet groove under the action of the spring.

[0008] Beneficial effects: When the device moves forward, the tennis balls gather at the lower part of the spiral shaft under the action of the guiding plates on both sides. The outwardly inclined guiding plates increase the tennis ball collection range and improve the collection efficiency. Start the first motor and the second motor. When the first motor rotates, it drives the rotating rod to rotate through the first wheel, belt, and second wheel. The rotation of the rotating rod drives the triangular rod to swing back and forth through the first connecting rod, and the back-and-forth swing of the triangular rod drives the flipping rod to flip up and down. After the second motor drives the spiral shaft to rotate, the spiral surfaces on both sides push the tennis balls into the collection ports on both sides respectively. The collection port is in the shape of a flared opening with a larger inner opening, so that the tennis balls on the ground climb from the ground to the upper ball outlet hole under the action of the spiral surface. The tennis balls enter the ball outlet groove through the ball outlet hole, which facilitates the tennis balls to smoothly enter the rotating arm hole from the goal hole. The upper opening of the ball outlet groove can prevent the spiral shaft from being blocked when the tennis balls entering the ball outlet groove are not taken out by the flipping rod. When the spiral shaft is blocked, the tennis balls in the ball outlet groove are squeezed out from the upper part of the ball outlet groove. When the flipping rod rotates to the lowest position, the rotating arm enters the corresponding side groove, and the back side of the rotating arm squeezes the stopper backward, aligning the rotating arm hole with the corresponding ball outlet groove. The tennis balls enter the rotating arm hole from the ball outlet groove through the goal hole. The tennis balls entering the rotating arm hole flip with the flipping rod. After the flipping rod flips to the upper part, the tennis balls in the rotating arm hole roll into the ball hopper from the goal hole in front of the ball hopper. After the flipping rod flips upward, the rotating arm leaves the side groove, and the stopper blocks the corresponding ball outlet groove under the action of the spring to prevent the tennis balls from entering the side groove. The first motor and the second motor rotate continuously, and the tennis balls are continuously sent into the upper ball hopper. Since the ball hopper for storing tennis balls is open at the upper part of the device, after the tennis balls are collected, the device is directly pushed in front of the tennis ball user, and the tennis ball user can directly pick them up, eliminating the steps of taking the tennis balls out of the collection device and then using them for training or competition, thus improving the efficiency of collecting and using tennis balls.

[0019] Reference Figure 1 , two symmetrical side grooves 116 are arranged on two sides of the machine base 110, a ball outlet groove 114 is arranged on the inner side of the front end of each side groove 116, a block 230 is slidably connected to the inner side of each side groove 116, and a spring 240 is fixedly connected to the rear side of each block 230 and the rear side of the side groove 116.

[0020] Reference Figure 5, a rotating arm 153 is provided inside the flipping rod 150. A rotating arm hole 154 through which the tennis ball passes is provided in the middle of the rotating arm 153. A scoring hole 155 is provided inside the end of the rotating arm hole 154. When the flipping rod 150 rotates to the lowermost position, the rotating arm 153 enters the corresponding side groove 116. The rear side of the rotating arm 153 presses the stopper 230 backward, and the rotating arm hole 154 is aligned with the corresponding ball outlet groove 114. When the flipping rod 150 rotates to the uppermost position, the rotating arm 153 leaves the side groove 116, and the stopper 230 blocks the ball outlet groove 114 on the corresponding side under the action of the spring 240.

[0021] Reference Figure 2 , 6 , a groove 111 is provided on the front side of the machine base 110. Two symmetric collecting ports 112 are provided on both sides of the groove 111. The collecting ports 112 are in the shape of a flared mouth with a larger inner opening. An outlet hole 115 through which the ball outlet groove 114 passes is provided in the middle of each collecting port 112. A guiding plate 113 inclined outward is provided outside each collecting port 112. A bearing seat 117 is provided above each collecting port 112. The bearing seat 117 is rotatably connected to both sides of the screw shaft 160. Two screw surfaces 161 with opposite helix directions are provided on the outer side of the screw shaft 160.

[0022] Reference Figure 7 , a ball hopper 260 is fixedly connected between the two side plates 118 on the upper part of the machine base 110. A scoring inlet 261 for the tennis ball to enter is provided on the front side of the ball hopper 260.

[0023] When using this device, push the device forward in the area where tennis balls need to be collected. When the device moves forward, the tennis balls are gathered under the lower part of the spiral shaft 160 under the action of the guiding plates 113 on both sides. The outwardly inclined guiding plates 113 make the collection range of the tennis balls larger and the collection efficiency of the tennis balls higher. Start the first motor 170 and the second motor 250. When the first motor 170 rotates, it drives the rotating rod 130 to rotate through the first pulley 180, the belt 190, and the second pulley 200. When the rotating rod 130 rotates, it drives the triangular rod 140 to swing back and forth through the first connecting rod 210. The back-and-forth swing of the triangular rod 140 drives the flipping rod 150 to flip up and down. After the second motor 250 drives the spiral shaft 160 to rotate, the spiral surfaces 161 on both sides respectively push the tennis balls into the collection ports 112 on both sides. The collection port 112 is in the shape of a flared port with a larger inner opening, so that the tennis balls on the ground rise from the ground to the upper ball outlet hole 115 under the action of the spiral surface 161. The tennis balls pass through the ball outlet hole 115 and enter the ball outlet groove 114, which facilitates the tennis balls to smoothly enter the rotating arm hole 154 from the goal hole 155. The upper opening of the ball outlet groove 114 can prevent the tennis balls entering the ball outlet groove 114 from causing the jamming of the spiral shaft 160 when not taken out by the flipping rod 150. When the spiral shaft 160 is jammed, the tennis balls in the ball outlet groove 114 are squeezed and discharged from the upper part of the ball outlet groove 114. When the flipping rod 150 rotates to the lowest part, the rotating arm 153 enters the corresponding side groove 116, and the rear side of the rotating arm 153 squeezes the stopper 230 backward, so that the rotating arm hole 154 is aligned with the corresponding ball outlet groove 114, and the tennis balls enter the rotating arm hole 154 from the ball outlet groove 114 through the goal hole 155. The tennis balls entering the rotating arm hole 154 flip with the flipping rod 150. After the flipping rod 150 flips to the upper part, the tennis balls in the rotating arm hole 154 roll from the goal opening 261 in front of the ball bucket 260 into the ball bucket 260. After the flipping rod 150 flips upward, the rotating arm 153 leaves the side groove 116, and the stopper 230 blocks the corresponding ball outlet groove 114 under the action of the spring 240 to prevent the tennis balls from entering the side groove 116. The first motor 170 and the second motor 250 keep rotating, and the tennis balls are continuously sent into the upper ball bucket 260. Since the ball bucket 260 for storing tennis balls is at the upper part of this device and is open, after the tennis balls are collected, directly push this device in front of the tennis ball user, and the tennis ball user can directly take them, saving the steps of taking the tennis balls from the collection device and then giving them to the trainers or players, thus improving the efficiency of collecting and using tennis balls.
