[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1 to Figure 5 In an embodiment of the utility model, a concrete additive feeding device includes a feeding device for feeding a concrete mixing tank, the feeding device includes an adding tank 1, the output end of the adding tank 1 is connected to a guide pipe 2 arranged in an inclined manner, the output end of the guide pipe 2 is connected to a steering pipe 4, the output end of the steering pipe 4 is vertically downward, and the output end of the steering pipe 4 is connected to a connecting pipe 5 with a conical hollow structure;

[0029] The output end of the connecting pipe 5 is connected to a rotation driving structure, which includes: a driving unit, a telescopic rotation unit 6;

[0030] The driving unit is used to drive the telescopic rotating unit 6 to rotate with the center of the output end of the connecting pipe 5 as the center of the circle;

[0031] The telescopic rotating unit 6 in the rotating state is used to scatter the additive into the concrete mixing equipment in a circumferential direction, and the length of the telescopic rotating unit 6 can be adjusted to adapt to concrete mixing equipment with different opening sizes;

[0032] The output end of the adding tank 1 is connected to the inner cavity of the guide tube 2, and the output end of the adding tank 1 is vertically downward;

[0033] The oblique lower end of the guide tube 2 is a closed structure, and the oblique upper end of the guide tube 2 is an open structure. A rotating motor 3 is installed at the closed end of the guide tube 2. The output end of the rotating motor 3 passes through the inner cavity of the guide tube 2 and is connected to the spiral feeding rod 10 in the inner cavity of the guide tube 2.

[0034] In this embodiment, when adding additives to a concrete mixing tank (such as a vertical flat mixer), the length of the telescopic rotating unit 6 is first adjusted according to the size of the top opening of the mixing tank, and the driving unit is started, and then the rotating motor 3 is started. The rotating motor 3 drives the spiral feeding rod 10 to rotate, and the rotating spiral feeding rod 10 conveys the additive in the adding tank 1 upward along the inner cavity of the guide tube 2 until the additive moves along the guide tube 2 to the opening position of the guide tube 2. At this time, the additive subsequently sent up by the spiral feeding rod 10 squeezes the additive at the opening position of the guide tube 2. The additive enters the steering tube 4 under the action of the squeezing force, and enters the connecting tube 5 under the subsequent additive pressure. After entering the connecting tube 5, the additive enters the telescopic rotating unit 6 along the connecting tube 5. At this time, the driving unit drives the telescopic rotating unit 6 to rotate, and the rotating telescopic rotating unit 6 sprinkles the additive circumferentially into the mixing tank.

[0035] Please refer to Figure 1 The driving unit includes a driving motor 7 mounted on the outer wall of the connecting pipe 5 through a mounting frame, the output end of the driving motor 7 is connected to a driving gear 8, and the upper outer wall of the telescopic rotating unit 6 is equipped with a passive gear 9;

[0036] The driving gear 8 is meshed with the driven gear 9.

[0037] In this embodiment: the driving motor 7 is connected to electric energy, the driving motor 7 runs, and the driving motor 7 drives the active gear 8 to rotate through the rotating shaft and the coupling. The rotation of the active gear 8 drives the passive gear 9 to rotate. The passive gear 9 is interference fitted on the outside of the telescopic rotating unit 6, so the telescopic rotating unit 6 can perform a circular motion.

[0038] Please refer to Figure 4 , Figure 4 and Figure 5 The telescopic rotation unit 6 includes an upper fixed tube 601 rotatably mounted on the bottom end of the connecting tube 5, and a lower sliding tube 602 slidably connected to the outer wall of a fixed inclined tube 604 of the upper fixed tube 601;

[0039] A sliding cavity 603 is provided in the sliding inclined tube portion of the lower sliding tube 602, and a fixed inclined tube 604 is slidably connected to the inner cavity of the sliding cavity 603;

[0040] The outer wall of the lower sliding tube 602 is provided with a screw hole 605, which is connected to the inner cavity of the sliding cavity 603, and the screw hole 605 is close to one end of the curved tube portion of the upper fixed tube 601;

[0041] An anti-slip portion 606 is formed at one end of the fixed inclined tube 604 located in the inner cavity of the sliding cavity 603 , and the anti-slip portion 606 is consistent with the sliding cavity 603 .

[0042] In this embodiment: when adjusting according to the top opening of the mixing tank, first loosen the bolt located in the screw hole 605. At this time, the extrusion force applied by the bolt on the fixed inclined tube 604 disappears, and it is impossible to form a sliding inclined tube limit for the lower sliding tube 602. At this time, the lower sliding tube 602 can be pulled, and the lower sliding tube 602 can slide downward or upward along the outer wall of the fixed inclined tube 604, so as to adjust the overall length of the telescopic rotating unit 6. When the length adjustment is completed, tighten the bolt again, and the tightened bolt end will effectively squeeze the outer wall of the fixed inclined tube 604, so as to limit the lower sliding tube 602 and prevent the lower sliding tube 602 from actively sliding.

[0043] Since the opening of the sliding cavity 603 matches the outer wall of the fixed oblique tube 604 and the anti-slip portion 606 is larger than the opening of the sliding cavity 603 , the lower sliding tube 602 and the upper fixed tube 601 can be prevented from separating during the sliding process.

[0044] Please refer to Figure 2-4 The upper part of the upper fixed tube 601 includes a first curved tube and a first vertical tube. The first vertical tube is rotatably connected to the bottom end of the connecting tube 5, and the inner cavity of the first vertical tube is equal to the minimum diameter of the bottom end of the connecting tube 5. The first curved tube is integrally formed at the bottom end of the first vertical tube. The lower part of the lower sliding tube 602 includes a second curved tube and a second vertical tube. The second curved tube is connected to the obliquely downward sliding inclined tube portion of the lower sliding tube 602, and the second vertical tube is integrally formed at the bottom end of the second curved tube.

[0045] In this embodiment, the structure of the upper fixed tube 601 and the lower sliding tube 602 can minimize the resistance encountered by the additive during the downward sliding process, and can prevent the additive from getting stuck during the sliding process.

[0046] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
