Abstract
Description
Technical Field
[0001] This utility model relates to the field of additive application technology, and in particular to a concrete mixing additive application device. Background Technology
[0002] A concrete mixing additive spraying device is a specialized piece of equipment used in the concrete production process to achieve precise and uniform dispensing of additives. Its core function is to inject various chemical additives (such as water-reducing agents, retarders, air-entraining agents, etc.) into the mixing system according to a preset ratio. Through mixing, the additives are fully mixed with the concrete raw materials, thereby improving the workability (such as fluidity and setting time) or durability (such as impermeability and frost resistance) of the concrete.
[0003] In the existing technology (publication number CN220052307U, named "Concrete Additive Feeding Device"), a feeding box is included. The side wall of the feeding box has a guide groove, and a receiving frame fixedly fitted inside the guide groove is attached to the receiving groove. The end of the receiving frame is attached to a transmission frame installed on the outer wall of the feeding box. The end of the transmission frame extends into the concrete processing tank. A mixing motor is installed on the surface of the concrete processing tank. A side plate is attached to the outer wall of the feeding box. Symmetrically arranged rotating rollers are installed between the inner wall of the side plate and the inner wall of the feeding box. A transmission chain plate is sleeved between the outer circumferences of the rotating rollers. An additive tray component is installed on the side wall of the transmission chain plate. This utility model provides continuous concrete additive feeding without intermittent start-stop operations, ensuring efficient concrete additive feeding.
[0004] In existing technologies, the location of concrete additives is fixed, and the position where the additives fall into the concrete mixing tank is also fixed. It takes a lot of time for the additives and concrete raw materials to mix evenly. Moreover, for liquid additives, if the feeding position is fixed, it will lead to excessively high local additive concentrations, which will affect the performance of the finished concrete.

A storage tank for holding additives is fixedly installed on the first mounting frame. A spraying mechanism is connected to the bottom of the storage tank. One end of the spraying mechanism is movably disposed inside the mixing tank.

[0011] Preferably, a riser is fixedly connected to the end of the conveying pipe away from the storage tank, and a sealing joint is provided at the connection between the conveying pipe and the riser.
[0012] Preferably, an inclined tube is fixedly connected to the bottom of the riser, the inclined tube is movably disposed in the movable groove, and a nozzle is provided at the bottom of the inclined tube.
[0013] Preferably, a spherical tube is provided in the middle of the inclined tube, and the spherical tube is rotatably installed in the spherical seat.
[0014] Preferably, the adjustment mechanism includes a drive motor, which is fixedly mounted on the upper surface of the top cover by a fixing bracket. A gear is fixedly connected to the output end of the drive motor, a gear ring is meshed on one side of the gear, a bearing is installed on one side of the gear ring, and the riser is installed inside the bearing.
[0015] Preferably, the gear ring is rotatably installed in a plurality of limiting frames, the limiting frames being circumferentially arranged outside the movable groove and fixedly connected to the upper surface of the top cover.
[0016] The concrete mixing additive spraying device provided in this embodiment of the invention has the following advantages compared with the prior art:
[0017] 1.

[0018] 2. This utility model drives a motor to rotate a gear, which in turn drives a gear ring to rotate. The gear ring then drives the riser to rotate around the central axis of the gear ring, thereby changing the angle of the inclined pipe and the nozzle. Through automated adjustment and multi-dimensional spraying, the mixing uniformity and production efficiency of concrete additives are significantly improved. Attached Figure Description

A storage tank 4 for holding additives is fixedly installed on the first mounting frame 1. A spraying mechanism 3 is connected to the bottom of the storage tank 4. One end of the spraying mechanism 3 is movably disposed inside the mixing tank 5. Several adjustment mechanisms 2 are provided on the upper circumference of the mixing mechanism for adjusting the spraying angle of the spraying mechanism 3.
[0032] The mixing mechanism includes a mixing tank 5, which is fixedly installed on the second mounting frame 6. A top cover 51 is fixedly installed on the upper end of the mixing tank 5. A mixing motor 52 is fixedly installed in the middle of the upper surface of the top cover 51. A rotating shaft 53 is fixedly connected to the output end of the mixing motor 52. A mixing blade 54 for mixing concrete is fixedly installed on the rotating shaft 53.
[0033] The mixing mechanism drives the rotating shaft 53 and mixing blades 54 to rotate via the mixing motor 52, mixing concrete materials and additives. The movable trough 511 provides space for the spraying mechanism 3 to move.
[0034] The top cover 51 has several movable slots 511, and several mounting plates 55 are fixedly installed on the lower surface of the top cover 51. A spherical seat 551 is provided on the mounting plate 55. The mounting plate 55 and the spherical seat 551 support the inclined tube 35 and the spherical tube 36 of the spraying mechanism 3, so that they can be adjusted at multiple angles.
[0035] The spraying mechanism 3 includes a conveying pipe 31, one end of which is fixedly connected to the storage tank 4, and a valve 34 is provided near the storage tank 4. The end of the conveying pipe 31 away from the storage tank 4 is fixedly connected to a riser 33. A sealing joint 32 is provided at the connection between the conveying pipe 31 and the riser 33. An inclined pipe 35 is fixedly connected to the bottom of the riser 33. The inclined pipe 35 is movably disposed in the movable groove 511. A nozzle 37 is provided at the bottom of the inclined pipe 35. A spherical tube 36 is provided in the middle of the inclined pipe 35. The spherical tube 36 is rotatably installed in the spherical seat 551.
[0036] The storage tank 4 is equipped with a delivery pump to deliver the additive. The additive flows through the delivery pipe 31 and the flow rate is controlled by the valve 34. It flows through the riser pipe 33 and the inclined pipe 35, and then is sprayed into the mixing tank 5 through the nozzle 37. The spherical tube 36 in the middle of the inclined pipe 35 is nested in the spherical seat 551, allowing the inclined pipe 35 to rotate freely in the movable groove 511 to adjust the spray angle.

The limiting brackets 22 are circumferentially arranged outside the movable groove 511 and are fixedly connected to the upper surface of the top cover 51.
[0038] The angle of the nozzle 37 is adjusted by the adjustment mechanism 2. Specifically, the drive motor 25 drives the gear 24 to rotate, the gear 24 drives the gear ring 21 to rotate, and the gear ring 21 drives the riser 33 to rotate around the central axis of the gear ring 21, thereby changing the angle of the inclined tube 35 and the nozzle 37. The limit frame 22 guides and limits the gear ring 21 to ensure the stability of the gear ring 21 during rotation.
[0039] In summary, the working principle of the concrete mixing additive spraying device according to this utility model embodiment is as follows:
[0040] The additive in the storage tank 4 is transported to the riser 33 and inclined pipe 35 by the delivery pump, and sprayed into the mixing tank 5 by the nozzle 37. The drive motor 25 drives the gear ring 21 to rotate, and the nozzle 37 rotates accordingly, so that the additive evenly covers different areas of the mixing tank 5, avoiding excessive local additive concentration, and thus more evenly mixing with the concrete raw materials. The mixing motor 52 drives the rotating shaft 53 and the mixing blades 54 to rotate, and mixes the concrete materials and additives.
[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
