DETAILED DESCRIPTION

[0025] The present invention is further described in detail below with reference to the accompanying drawings.

[0026] like Figures 1 to 8As shown, in order to achieve the technical effect of "continuous mixing and processing of concrete cannot be completed in a construction environment where a large amount of concrete processing is required", the structure and function of a highly frost-resistant and salt-resistant concrete preparation device are described in detail below;

[0027] A highly frost-resistant and salt-resistant concrete preparation device comprises a mixing drum 11, wherein the front and rear ends of the mixing drum 11 are both provided with a spiral shaft 22, and the middle part of the mixing drum 11 is provided with a liquid injection section 12;

[0028] The injection section 12 is provided with a plurality of injection holes 13, and each injection hole 13 is provided with a one-way mechanism 18;

[0029] The mixing drum 11 is fixedly connected to a plurality of sliding brackets 14, and each sliding bracket 14 is rotatably connected to a screw rod 15;

[0030] The sliding bracket 14 is slidably connected with a sliding seat 51, which is connected to the screw rod 15 by threads, and the sliding seat 51 is fixedly connected with a connecting pipe 52, and the connecting pipe 52 is fixedly connected with an arc cavity 53, and the arc cavity 53 is slidably connected to the injection section 12;

[0031] A sealing strip is provided between the arc cavity 53 and the injection section 12;

[0032] The sliding bracket 14 is fixedly connected with a power mechanism I for driving the screw rod 15 to rotate;

[0033] The front and rear ends of the mixing drum 11 are respectively provided with a feeding pipe 16 and a discharging pipe 17;

[0034] The feed pipe 16 and the discharge pipe 17 are both provided with a rotating disk 21, each rotating disk 21 is fixedly connected with a screw shaft 22, the two screw shafts 22 are both located in the mixing drum 11, and the mixing drum 11 is fixedly connected with a power mechanism II for driving the rotating disk 21 to rotate;

[0035] The front and rear ends of the mixing drum 11 are fixedly connected with support brackets 31, a rotating drum 32 is rotatably connected between the two support brackets 31, the rotating drum 32 is arranged in the mixing drum 11, the spiral shaft 22 is located between the rotating drum 32 and the mixing drum 11, a plurality of sliding holes 33 are arranged in the middle of the rotating drum 32, and a power mechanism III for driving the rotating drum 32 to rotate is fixedly connected to the mixing drum 11;

[0036] A support column 41 is fixedly connected inside the rotating cylinder 32, and a plurality of telescopic mechanisms 42 are fixedly connected to the support column 41. A stirring plate 43 is fixedly connected to the telescopic end of each telescopic mechanism 42, and the stirring plate 43 is slidably connected inside the sliding hole 33;

[0037] When in use, the raw materials of concrete are introduced into the feed pipe 16, and the power mechanism II is started. The power mechanism II is preferably a servo motor, and the output shaft of the power mechanism II starts to rotate, and the output shaft of the power mechanism II drives the screw shaft 22 to rotate. When the screw shaft 22 rotates, a lateral driving force is generated to push the raw materials of concrete to move, so that the raw materials of concrete move from the feed pipe 16 to the discharge pipe 17;

[0038] The raw materials of concrete are passed through the feeding pipe 16 to the injection section 12 between the discharge pipe 17, and the power mechanism III is started. The power mechanism III is preferably a servo motor. The output shaft of the power mechanism III starts to rotate, and the output shaft of the power mechanism III drives the rotating cylinder 32 to rotate. The rotating cylinder 32 drives the support column 41 to rotate. The support column 41 drives multiple telescopic mechanisms 42 to rotate. The telescopic mechanism 42 drives the stirring plate 43 to rotate. The telescopic mechanism 42 is started. The telescopic mechanism 42 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism 42 drives the stirring plate 43 to move, so that the stirring plate 43 slides in the sliding hole 33, as shown in FIG. Figure 2 As shown, the stirring plates 43 extend between the liquid injection section 12 and the rotating drum 32, and when the raw materials of the concrete pass through the liquid injection section 12 between the feeding pipe 16 and the discharging pipe 17, the multiple stirring plates 43 move to stir the raw materials of the concrete;

[0039] At the same time, under the continuous rotation of the two screw shafts 22, the raw materials of the concrete are continuously passed through the multiple mixing plates 43, thereby completing the mixing, thereby achieving uninterrupted and large-scale mixing of the concrete, meeting a large number of construction needs;

[0040] Furthermore, in order to increase the mixing speed of the concrete, the telescopic mechanism 42 can be continuously started during the mixing process, so that the telescopic end of the telescopic mechanism 42 continuously reciprocates, so that the telescopic end of the telescopic mechanism 42 continuously drives the stirring plate 43 to move, thereby increasing the movement trajectory of the stirring plate 43, thereby increasing the movement of the concrete, and then the output shaft of the power mechanism II can increase the rotation speed, thereby accelerating the mixing efficiency;

[0041] At the same time, the chemical agents required for the preparation of highly frost-resistant and salt-resistant concrete are continuously introduced into the connecting pipe 52 in advance. The chemical agents may be antifreeze agents, bubble forming agents, high-performance water reducing agents, etc., so that the chemical agents enter the arc cavity 53 through the connecting pipe 52, and enter the injection section 12 through the multiple injection holes 13 provided on the injection section 12 in the arc cavity 53, thereby achieving mixing of concrete raw materials and chemical agents in the injection section 12;

[0042] Furthermore, the power mechanism I can be started according to the addition time required for different medicines. The power mechanism I is preferably a servo motor. The output shaft of the power mechanism I drives the screw 15 to rotate. When the screw 15 rotates, it drives the sliding seat 51 to move through the thread. The sliding seat 51 drives the connecting pipe 52 to move, and the connecting pipe 52 drives the arc cavity 53 to move, so that the arc cavity 53 slides on the injection section 12, thereby adjusting the position of the arc cavity 53, and then adjusting the timing of adding the corresponding chemical agent.
