[0025] This disclosure aims to address the existing problems in concrete production, such as the lack of room for improvement in areas like mixing uniformity, energy consumption control, dust and noise suppression, as the construction industry continues to demand higher standards for concrete quality, production efficiency, and environmental performance. Therefore, this disclosure proposes a high-strength concrete production mixing device. By incorporating a feeding assembly and a mixing assembly, and using an auxiliary mechanism within the feeding assembly to assist in feeding the raw materials upon entry, it avoids the blockage of the buffer chamber by raw materials, thus preventing concrete production from stopping. Furthermore, by replacing the traditional rotary mixing method with a mixing assembly where the mixing shaft drives the mixing arm, the concrete is mixed more uniformly, thereby improving production efficiency.

[0026] like Figures 1 to 5 As shown, a high-strength concrete production mixing device includes a support frame 1, a feeding assembly 2, a power assembly 3, and a mixing assembly 4. The support frame 1 is fixed, and the feeding assembly 2 is installed on the support frame 1. The feeding assembly 2 is used to convey raw materials to the mixing assembly 4 for mixing. The power assembly 3 is installed on one side of the feeding assembly 2 and is used to provide power to the mixing assembly 4. The mixing assembly 4 is installed at the output end of the power assembly 3 and is used to uniformly mix the concrete raw materials and then convey them out.

[0027] By setting up a feeding assembly 2 and a mixing assembly 4, the auxiliary mechanism 24 in the feeding assembly 2 assists in feeding the raw materials when they enter, thereby preventing the raw materials from clogging the buffer chamber 23 and causing the concrete production to stop. At the same time, the mixing assembly 4, which uses a mixing shaft 44 to drive the mixing arm 45 to rotate, replaces the transmission-based rotation mixing method, which can make the concrete mix more evenly and improve production efficiency.

[0028] like Figures 1 to 3 As shown, the feeding assembly 2 includes a feeding box 21, a feeding port 22, a buffer chamber 23, an auxiliary mechanism 24, and a conveying chamber 25. The feeding box 21 is mounted on the support frame 1 and is used to mix and convey raw materials. The feeding port 22 is located at the top of the feeding box 21 and is used to feed raw materials into the feeding box 21. The buffer chamber 23 is located at the bottom of the feeding box 21 and is used to cooperate with the auxiliary mechanism 24 to complete the initial mixing of raw materials. The auxiliary mechanism 24 is installed in the buffer chamber 23 to prevent clogging. The auxiliary mechanism 24 is used to perform initial mixing of raw materials and prevent raw materials from clogging the feeding assembly 2. The conveying chamber 25 is installed at the bottom of the buffer chamber 23 and is used to convey the initially mixed raw materials to the stirring assembly 4 for stirring.

[0029] During operation, the staff put the raw materials into the feed box 21. Under the action of gravity, the raw materials flow into the buffer chamber 23. While flowing, they are initially mixed by the auxiliary mechanism 24, which also prevents the raw materials from clogging the feed assembly 2. Then, the raw materials pass through the buffer chamber 23 to the transport chamber and finally flow into the stirring assembly 4 for stirring and preparation.

[0030] The above-mentioned feeding component 2 can be used to pre-treat the raw materials and then mix them. At the same time, due to the setting of buffer chamber 23 and conveying chamber 25, problems can be dealt with in a timely manner, avoiding the situation where the raw materials block the feeding component 2 and thus the feeding component 2 cannot convey the raw materials into the mixing component 4.

[0031] like Figure 3As shown, the auxiliary mechanism 24 includes a rotating motor 241, a rotating shaft 242, a first gear 243, a second gear 244, and a spiral fan blade 245. The rotating motor 241 is installed on one side of the buffer chamber 23 and drives the rotating shaft 242 to rotate. The rotating shafts 242 are symmetrically installed inside the buffer chamber 23. Each rotating shaft 242 drives the first gear 243 to rotate. One of the rotating shafts 242 is connected to the output end of the rotating motor 241. The first gear 243 is installed on the rotating shaft 242, and the first gear 243 drives the second gear 244 to rotate. The first gear 243 meshes with the second gear 244 on one side, and the second gear 244 is installed on the rotating shaft 242. The rotation of the second gear 244 drives the other rotating shaft 242 to rotate in the opposite direction. Spiral fan blades 245 are installed on both rotating shafts 242, and the rotation of the spiral fan blades 245 achieves pretreatment of the raw materials.

[0032] During operation, the rotating motor 241 drives the rotating shaft 242 to rotate, the rotating shaft 242 drives the first gear 243 to rotate, the first gear 243 drives the second gear 244 to rotate, and the rotating second gear 244 drives another rotating shaft 242 to rotate in the opposite direction. Therefore, the rotation of the two rotating shafts 242 drives the spiral fan blades 245 to rotate in opposite directions, thereby realizing the pretreatment of raw materials and avoiding the raw materials from clogging the feeding assembly 2.

[0033] The auxiliary mechanism 24 described above can be used to pre-treat the raw materials when they are being transported into the mixing component 4, thereby improving the efficiency of concrete preparation. At the same time, the auxiliary mechanism 24 can also break up clumps of raw materials while they are being transported, so as to prevent the raw materials from clogging the feeding component 2 and thus reducing the efficiency of concrete preparation.

[0034] like Figure 3 As shown, the spiral directions of the spiral fan blades 245 on the two rotating shafts 242 are opposite. Setting the spiral fan blades 245 on the rotating shafts 242 to be opposite can enable the spiral fan blades 245 to fully compress the raw materials during the processing of the raw materials, thereby achieving a preliminary crushing effect and avoiding clogging of the feeding component 2.

[0035] like Figure 1 and Figure 5As shown, the power assembly 3 includes a power motor 31, a driving pulley 32, a driven pulley 33, a reducer 34, a first reduction gear 35, a second reduction gear 36, a third gear 37, and a fourth gear 38. The power motor 31 is mounted on one side of the support frame 1 and drives the driving pulley 32 to rotate. The driving pulley 32 is mounted on the power motor 31, and its rotation drives the driven pulley 33 to rotate. A reducer 34 is mounted on one side of the power motor 31 and converts the high-speed rotation of the driven gear into the speed of the first reduction gear 35. The reducer 34 has a driven pulley 33 mounted on one side, which drives the first reduction gear 35 and the second reduction gear 36 to rotate. The reducer 34 also has a driven pulley 33 mounted on the other side, which meshes with the first reduction gear 35 and the second reduction gear 36. The first reduction gear 35 and the second reduction gear 36 drive the third reduction gear 37 and the fourth reduction gear 38 to rotate, and the rotating third reduction gear 37 and the fourth reduction gear 38 drive the stirring assembly 4 to rotate.

[0036] During operation, the power motor 31 rotates, driving the drive pulley 32 to rotate. The rotating drive pulley 32 drives the driven pulley 33 to rotate. With the cooperation of the reducer 34, the driven pulley 33 drives the first reduction gear 35 and the second reduction gear 36 to rotate at a reduced speed. The rotating first reduction gear 35 and the second reduction gear 36 drive the third gear 37 and the fourth gear 38 to rotate, thereby driving the stirring component 4 to rotate to complete the stirring work.

[0037] Through the reasonable coordination and transmission of the power motor 31, pulley, reducer 34 and multiple sets of gears, the power can be effectively converted and transmitted, realizing the function of speed reduction and torque increase. This allows the stirring component 4 to obtain a suitable speed for stable stirring. At the same time, its structure is relatively compact, the layout of each component is clear, which is convenient for installation and maintenance. Moreover, the transmission process is relatively smooth, which helps to improve the efficiency and quality of stirring work and ensures the stable and reliable operation of the entire equipment.

[0038] like Figure 4As shown, the mixing assembly 4 includes a mixing chamber 41, a first cover plate 42, a second cover plate 43, a mixing shaft 44, a mixing arm 45, a mixing block 46, and a discharge port 47. The mixing chamber 41 is mounted on the support frame 1 and is used to store the raw materials conveyed by the feeding assembly 2. The mixing chamber 41 is equipped with a first cover plate 42 and a second cover plate 43. The first cover plate 42 is connected to the conveying chamber 25 and is used to cooperate with the feeding assembly 2 to complete the feeding. The second cover plate 43 is used to seal the mixing chamber 41. A mixing shaft 44 is symmetrically arranged inside the mixing chamber 41. The mixing shaft 44 is used to drive the mixing arm 45 to rotate. The mixing shaft 44 extends out of the mixing chamber 41 and is connected to the third gear 37 and the fourth gear 38. The mixing arm 45 is arranged in an array on the mixing shaft 44. The mixing arm 45 is used to drive the mixing block 46 to rotate. The mixing block 46 is installed on the mixing arm 45. The mixing block 46 is used to fully mix the raw materials. The bottom of the mixing chamber 41 has a discharge port 47 for discharging the mixed concrete.

[0039] During operation, after the raw materials enter the mixing chamber 41 through the feeding component 2, the power component 3 drives the mixing shaft 44 to rotate. The rotating mixing shaft 44 drives the mixing arm 45 to rotate, and the rotating mixing arm 45 drives the mixing block 46 to rotate, thereby achieving full mixing of the concrete. After the mixing is completed, it is conveyed out from the discharge port 47.

[0040] With the above design, the mixing shaft 44 is symmetrically arranged and connected to gears to ensure stable rotation of the mixing arm 45. The mixing blocks 46 arranged in an array on the mixing arm 45 can fully mix the raw materials, making the concrete uniformly mixed. The bottom discharge port 47 is designed to facilitate the smooth discharge of concrete after mixing. The entire mixing process is efficient, uniform, and easy to operate, effectively improving the quality and efficiency of concrete mixing.

[0041] like Figure 5 As shown, an inspection groove 48 is provided on the second cover plate 43, and an observation glass 49 is installed in the inspection groove 48. The above design allows the staff to observe the mixing situation inside the mixing chamber 41 in real time. The mixing status of the raw materials can be seen directly through the observation glass 49, ensuring the uniformity of mixing and timely detection and handling of possible problems. At the same time, the design of the inspection groove 48 makes the installation and replacement of the observation glass 49 more convenient, improving maintenance efficiency. Finally, the observation glass 49 usually has good sealing performance and will not affect the sealing of the mixing chamber 41, ensuring the normal operation of the mixing process.

[0042] The overall working process is as follows: During operation, the operator puts the raw materials into the feed box 21. Under the action of gravity, the raw materials flow into the buffer chamber 23 within the feed box 21. The rotating motor 241 drives the rotating shaft 242 to rotate, which in turn drives the first gear 243 to rotate. The first gear 243 then drives the second gear 244 to rotate, which in turn drives the other rotating shaft 242 to rotate in the opposite direction. Therefore, the rotation of the two rotating shafts 242 drives the spiral fan blades 245 to rotate in opposite directions, thereby achieving pretreatment of the raw materials and preventing the raw materials from clogging the feed assembly 2. Then, the raw materials pass through the buffer chamber 23, flow into the transport chamber, and finally flow into the mixing assembly 4. The concrete is mixed and prepared inside the container. At this time, the power motor 31 rotates, driving the drive pulley 32 to rotate. The rotating drive pulley 32 drives the driven pulley 33 to rotate. With the cooperation of the reducer 34, the driven pulley 33 drives the first reduction gear 35 and the second reduction gear 36 to rotate at a reduced speed. The rotating first reduction gear 35 and the second reduction gear 36 drive the third gear 37 and the fourth gear 38 to rotate, which in turn drives the mixing shaft 44 to rotate to complete the mixing work. The rotating mixing shaft 44 drives the mixing arm 45 to rotate, and the rotating mixing arm 45 drives the mixing block 46 to rotate, thereby achieving full mixing of the concrete. After the mixing is completed, the concrete is conveyed out from the discharge port 47.
