Detailed Description of the Specific Embodiment

[0027] Now, the present utility model will be further described in detail with reference to the drawings.

[0028] Please refer to Figures 1-4 As shown, in this embodiment, a wax cleaning ball delivery device is provided, including a storage rack 1, an L-shaped bracket 2 and a support block 3. A notch is provided at the top of the storage rack 1 to facilitate the movement of the delivery personnel to the storage rack 1. The bottom of the L-shaped bracket 2 is fixed to the top of the storage rack 1. The L-shaped bracket 2 can limit the upper part of the ball delivery pipe 5, improving the stability of the ball delivery pipe 5. The support block 3 is fixed to the top of the storage rack 1. The support block 3 is located inside the L-shaped bracket 2. The support block 3 has a supporting effect on the rotary timing delivery component 4. A rotary timing delivery component 4 is rotatably installed on one side inside the L-shaped bracket 2. The storage rack 1 and the L-shaped bracket 2 are fixedly provided with a ball delivery pipe 5 through them. A part of the rotary timing delivery component 4 is located inside the ball delivery pipe 5. A buffer component 9 is fixedly installed on the inner wall of the ball delivery pipe 5.

[0029] A top cover 6 is clamped to the top of the ball delivery pipe 5, which can prevent dust from falling into the oil pipe 8 through the ball delivery pipe 5. A semi-spherical rack 7 is fixed to one side of the ball delivery pipe 5 to facilitate the rotary delivery of the wax cleaning balls. An oil pipe 8 is provided at the bottom of the ball delivery pipe 5. The buffer component 9 is located above the oil pipe 8.

[0030] One application of this embodiment is as follows: Movable wheels are provided at the bottom of the storage rack 1 to facilitate the adjuster to adjust the position of the storage rack 1. The adjuster can place the storage rack 1 above the oil pipe 8 by using the notch, so that the bottom of the ball throwing pipe 5 is located above the oil pipe 8. Then, the top cover 6 is removed, and the paraffin removal ball is placed inside the ball throwing pipe 5. After placement, the top cover 6 is covered to prevent a large amount of dust from falling into the oil pipe 8 through the ball throwing pipe 5. Then, the rotary timing delivery component 4 is used to deliver the paraffin removal ball at a fixed time. During the falling process of the paraffin removal ball, it first falls onto the top of the buffer component 9, and the buffer component 9 buffers the gravity of the paraffin removal ball to prevent damage to the oil pipe 8.

[0031] The rotary timing delivery component 4 includes a rotary motor 401 and a rotating shaft 402. The rotary motor 401 is fixedly installed on the top of the support block 3. The rotating shaft 402 is installed at the output end of the rotary motor 401. The other end of the rotating shaft 402 is rotatably installed on one side inside the L-shaped bracket 2. An active meshing gear 403 is fixed on the outer side of the rotating shaft 402. A connecting shaft 405 is rotatably installed on one side inside the L-shaped bracket 2. A driven meshing gear 404 is fixed on the outer side of the connecting shaft 405. The active meshing gear 403 and the driven meshing gear 404 are meshed with each other, so that the active meshing gear 403 and the driven meshing gear 404 can rotate simultaneously. The other end of the connecting shaft 405 is fixed with a rotating member 406. An arc-shaped groove is provided on the rotating member 406. The rotating member 406 is located inside the ball throwing pipe 5.

[0032] When this embodiment is in use, the paraffin removal ball is placed inside the ball throwing pipe 5. It can fall into the arc-shaped groove by relying on its own gravity. When the rotary motor 401 works, it can drive the rotating shaft 402 to rotate. The active meshing gear 403 can rotate with the rotation of the rotating shaft 402. The active meshing gear 403 and the driven meshing gear 404 are meshed with each other, so as to drive the driven meshing gear 404, the connecting shaft 405 and the rotating member 406 to rotate, enabling the paraffin removal ball to be delivered at a fixed time. By adjusting the rotation speed of the rotary motor 401, the paraffin removal ball can be delivered at a fixed time, improving the safety of the ball throwing device.

[0033] The buffer component 9 includes a buffer frame 901 and a spring 902. The outer side of the buffer frame 901 is fixed on the inner wall of the ball throwing pipe 5. One end of the spring 902 is fixed on the inner wall of the buffer frame 901, and the other end of the spring 902 is fixed with a buffer plate 903. The spring 902 and the buffer plate 903 are both arranged at a certain angle with the buffer frame 901 to facilitate the falling of the paraffin removal ball.

[0034] When in use in this embodiment, when the paraffin removal ball drops to the top of the buffer plate 903, the paraffin removal ball itself has a certain gravity, which can squeeze the buffer plate 903, thereby achieving the effect of buffering the paraffin removal ball. The spring 902 contracts, and there is a force inside the spring 902 to restore its original state. When the paraffin removal ball drops into the oil pipe 8, under the action of the spring 902, the buffer plate 903 moves back to its original position, so that the next paraffin removal ball can be buffered.

[0035] The present utility model is not limited to the above embodiments. Anyone should know that structural changes made under the inspiration of the present utility model, as long as they have the same or similar technical solutions as the present utility model, fall within the protection scope of the present utility model. The technologies, shapes, and structures not described in detail in the present utility model are all well-known technologies.
