Description

Technical Field

[0001] The invention relates to the technical field of concrete production, and in particular to a green production line for continuously graded high-quality concrete. Background Art

[0002] In today's era, the sustained development of the global economy and the steady growth of the population have jointly promoted the rapid acceleration of the urbanization process. As one of the core driving forces of urbanization, the construction industry is booming at an unprecedented scale and speed. Various engineering projects have sprung up like mushrooms after rain, from towering skyscrapers to build the city's skyline, to the crisscrossing bridges and tunnels connecting the vast land's traffic veins, to the thousands of miles of highways and railways that expand the spatial dimension of regional development, and the industrial and civil buildings throughout the city and countryside meet people's diverse production and living needs. All of them have a huge and continuously growing demand for concrete as a basic building material. The quality of concrete can be called the lifeline of construction projects. It not only directly determines the safety of the building structure in terms of bearing pressure and resisting natural disasters, but also profoundly affects the durability of the building in the long-term use process, such as key properties such as impermeability and corrosion resistance. It is also closely related to the functionality of the building. For example, the thermal insulation performance of concrete is directly related to the comfort and energy consumption level of the indoor environment. With the continuous innovation and progress of modern architectural design concepts and people's increasing requirements for building quality, the construction industry has set increasingly stringent standards for the performance indicators of concrete, requiring it not only to have basic characteristics such as high strength and high durability, but also to pose new challenges in terms of working performance and environmental performance. Therefore, a continuous grading high-quality concrete green production line is designed.

[0003] Traditional concrete production methods often have many problems. In terms of raw material processing, the grading of aggregates such as sand and gravel is difficult to accurately control, resulting in unstable and unsatisfactory performance of concrete. In the concrete mixing process, traditional mixing equipment usually adopts a single mixing method, which is not uniform enough and prone to material agglomeration or segregation, seriously affecting the quality uniformity and strength stability of concrete. In addition, the connection between the various links of the traditional concrete production line is not tight and smooth enough. From the feeding of raw materials to the discharging of finished concrete, the entire process takes a long time and cannot meet the fast and efficient construction needs of modern large-scale construction projects.

[0061] The working principle of this embodiment is as follows: First, in the raw material preparation stage, aggregates such as sand and gravel are transported to the crushing bin 2 through the sand and gravel feeding conveyor belt 242 on the fixed seat 24, and the No. 5 motor 243 drives the sand and gravel feeding conveyor belt 242, and the sprocket on its output shaft drives the driving roller of the conveyor belt to rotate through the transmission chain, thereby realizing a stable feeding process. At the same time, the baffle plate 231 in the feed bin 23 can be adjusted according to production needs by rotating the toggle rod 232 and using the arc groove plate 2321 and the locking screw 2322 to adjust the angle, so as to accurately control the flow rate and speed of cement and other additives entering the crushing bin 2, and the flow rate and speed of cement and other additives entering the crushing bin 2, the No. 4 motor 22 is started, and the pulley on its output shaft drives the No. 1 crushing shaft 21 and the No. 2 crushing shaft 241 to rotate at high speed through the belt. The two crushing shafts cooperate with each other to strongly crush and refine the aggregate to meet the required grading requirements. The crushed materials fall into the discharge hopper 25, and the No. 6 motor 2541 drives the No. 3 gearbox 254, which in turn drives the No. 1 material-dispensing wheel 251 to rotate. Through the belt connection, the No. 1 material-dispensing wheel 251 drives the No. 2 material-dispensing wheel 252 and the No. 3 material-dispensing wheel 253 to rotate synchronously in turn, and the crushed materials are evenly and stably delivered to the concrete mixing bin 1. The motor 12 is running, and the pulley on its output shaft drives the No. 1 rotating column 13 and the No. 2 rotating column 14 to rotate through the belt, so that the stirring belt 17 performs preliminary stirring on the materials entering the mixing bin. At the same time, the No. 2 motor 1341 drives the No. 1 gearbox 134 to drive the screw rod 133 to rotate. Since the screw rod 133 is threadedly matched with the threaded hole on the movable seat 135, and the movable seat 135 is restricted by the rail rod 136 to only move along its axial direction, the rotation of the screw rod 133 can make the movable seat 135 move forward and backward, thereby driving the stirring rod 1351 to further stir and mix the materials, ensuring that the concrete is smooth. Various ingredients are fully and evenly mixed together to improve the quality of concrete. After mixing is completed, the No. 3 motor 152 drives the No. 2 gearbox 151 to drive the spiral roller in the material output pipe 15 to rotate, and the mixed concrete is transported out through the material output pipe 15. In terms of installation and maintenance of the material output pipe 15, the hydraulic rod 156 on the side seat 153 can drive the connecting plate 155 to move up and down through the extension and contraction of the piston rod, so that the movable arm 154 rotates around the pin shaft, thereby realizing the clamping or loosening of the material output pipe 15 by the left end clamping plate 1541, which is convenient for the installation, disassembly and maintenance operations of the material output pipe 15.
