Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Combination Figures 1-4 A tennis ball collecting vehicle includes a vehicle body 1, with rollers 2 movably mounted on both sides of the vehicle body 1 near the front and rear ends, a collecting roller 3 fixedly connected between the two rollers 2 at the front end, a push rod 4 fixedly mounted on the top of the vehicle body 1 near the rear end, a transmission mechanism 5 mounted on the top of the vehicle body 1, and a collecting mechanism 6 mounted on the front of the vehicle body 1.

[0025] See Figure 2 Furthermore, the transmission mechanism 5 includes a transmission box 7 and two conveyor belts 8. The transmission box 7 is fixedly installed on the top of the vehicle body 1. The two conveyor belts 8 are movably installed inside the transmission box 7. A top frame 9 is fixedly installed between the two push rods 4 and at the top of the transmission box 7. A fixed box 10 is installed on the top of the top frame 9 and outside the rollers of the two conveyor belts 8. Both ends of the roller at the top of one conveyor belt 8 are fixedly connected to shafts 11. One end of the roller at the top of the other conveyor belt 8 is fixedly connected to the same shaft 11. A protective sleeve 13 is sleeved on the outside of the shaft 11. Rotary teeth 14 are fixedly installed on the outer ends of the shafts 11 at the corresponding ends of the rollers at the top of the two conveyor belts 8. A rocker plate 12 is installed on the outer end of the shaft 11 at the other end of the roller at the top of the front conveyor belt 8.

[0026] Both the conveyor box 7 and the conveyor belt 8 are inclined. The upper and lower ends of the conveyor box 7 are fixed to the vehicle body 1 and the top frame 9 respectively. The two sides between the two conveyor belts 8 are sealed by the conveyor box 7. The two conveyor belts 8 are used to transport tennis balls.

[0027] The shaft 11 passes through the inner and outer sides of the fixed box 10 and the top frame 9 and is rotatably arranged. The protective sleeve 13 is fixed to the fixed box 10 and the top frame 9. The protective sleeve 13 is sleeved on the outside of the shaft 11 and is movably connected. The protective sleeve 13 is used to protect the shaft 11 and prevent the tennis ball from contacting the rotating shaft 11.

[0028] The two rotating teeth 14 are meshed together, the rollers in the two conveyor belts 8 rotate in opposite directions, the rocker plate 12 drives the shaft 11 to rotate, and the two conveyor belts 8 rotate simultaneously through the meshing of the rotating teeth 14.

[0029] Specifically, by shaking the rocker 12, the corresponding conveyor belt 8 is driven to rotate. Under the meshing action of the rotating teeth 14, another conveyor belt 8 is driven to rotate. The tennis ball is located inside the vehicle body 1 and rolls backward to contact the conveyor belt 8. The two conveyor belts 8 transport the tennis ball upward to the top frame 9, increasing the storage space for the tennis ball, so as to facilitate the retrieval and use of the tennis ball.

[0030] Example 2

[0031] See Figure 3 Furthermore, based on Embodiment 1, the collecting mechanism 6 includes two fixed shafts 15 and two retractable sleeves 16. The two fixed shafts 15 are respectively fixedly installed on the front side of the vehicle body 1. The two retractable sleeves 16 are respectively movably installed at the front end of the two fixed shafts 15. A telescopic plate 17 is movably installed through the front end of the retractable sleeve 16. A universal wheel 18 is installed at the bottom of the telescopic plate 17 near the front end. A protective wheel 19 is installed at the front end of the telescopic plate 17. A hanging plate 20 is movably installed on the inner side of the telescopic plate 17. A telescopic column 21 is movably installed through the interior of the telescopic plate 17.

[0032] The telescopic column 21 is set to extend and retract inward and outward through the spring inside the telescopic plate 17. The hanging plate 20 is connected to the telescopic plate 17 through a hinge. The telescopic column 21 automatically pops outward through the spring inside the telescopic plate 17, automatically opening the hanging plate 20. The hanging plate 20 is used to draw the tennis ball inward.

[0033] The telescopic plate 17 is slidably disposed inside the shrink sleeve 16 and is rotatably disposed at the front end of the fixed shaft 15. The telescopic plate 17 is used to increase the collection range of tennis balls.

[0034] Specifically, the shrink sleeve 16 rotates through the connection of the fixed shaft 15, and the telescopic plate 17 extends and retracts inside the shrink sleeve 16. Both are fixed under the action of friction to facilitate overall folding and storage, reduce external scratches, and increase the collection range of tennis balls. The tennis balls are drawn inward by the hanging plate 20, and the hanging plate 20 is adapted to rotate by the extension and retraction of the telescopic column 21.

[0035] In actual operation, the push rod 4 pushes the vehicle body 1, and the vehicle body 1 moves through four rollers 2. The two rollers 2 at the front end drive the collecting roller 3 to rotate synchronously. The tennis ball comes into contact with the collecting roller 3 and is collected in the vehicle body 1 under the action of squeezing and rotation.

[0036] During collection and transfer, the tennis balls collected in the vehicle body 1 roll backward. By shaking the rocker 12, the corresponding shaft 11 is rotated, which drives the corresponding conveyor belt 8 to rotate. Through the meshing of the rotating teeth 14, the other conveyor belt 8 rotates in the opposite direction. The tennis balls rolling backward come into contact with the outer surface of the conveyor belt 8 and are conveyed upward to the top frame 9 through the two conveyor belts 8, which increases the storage space and makes it easier to pick up and use.

[0037] During the storage and collection process of vehicle body 1, the telescopic plate 17 retracts into the telescopic sleeve 16. The telescopic sleeve 16 is rotated and folded by the fixed shaft 15, which reduces the space occupied when the vehicle is stored statically. By unfolding the telescopic sleeve 16 and the telescopic plate 17 and automatically fixing them under the action of friction, the collection range is increased. The telescopic column 21 pushes open the hanging plate 20 through the spring inside the telescopic plate 17, and the hanging plate 20 pulls the tennis ball inward.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
