Description

Technical Field

[0001] The utility model relates to the technical field of batching and mixing, and particularly relates to a batching and mixing device for concrete production. Background Art

[0002] As a basic material in the construction industry, the efficiency and quality of the production process of concrete directly affect the quality and cost of construction projects. The batching and mixing device for concrete production is a key equipment in the concrete preparation process, which is responsible for mixing raw materials such as cement, aggregates, and water in a certain proportion to form uniform concrete. With the development of the construction industry, the requirements for the production efficiency and quality of concrete are getting higher and higher. Therefore, it is particularly important to improve the performance of the batching and mixing device.

[0003] In the process of concrete production, the preheating of raw materials is an important step, which helps to improve the plasticity and workability of concrete. However, there are some defects in the existing devices when preheating raw materials. Usually, heating wires are arranged at the feeding pipes, and the raw materials are heated when passing through the pipes. But due to the overly concentrated feeding, all raw materials cannot be effectively preheated, and only the raw materials close to the pipe wall can be preheated. The materials located in the center are far from the heat source, so the preheating effect is not good, resulting in a reduction in the mixing efficiency of concrete. Content of the Utility Model

[0004] In order to overcome the above technical problems, the purpose of the present utility model is to provide a batching and mixing device for concrete production. By driving multiple round-headed bumps to rotate in the forward direction by a motor, the raw materials are stirred to accelerate the mixing of the edge materials and the materials located in the center, improve the preheating uniformity and preheating effect. By dispersing the raw materials concentrated inside the cylinder into a plurality of first round pipes, the heat absorption area is effectively increased, so that heat can be transferred to the raw materials more quickly and evenly, thereby shortening the preheating time and improving the mixing efficiency.

[0039] During specific implementation, after the feeding is completed, the round head bump 239 stops rotating, making its position correspond to the first round tube 211. The motor 231 drives the second one-way shaft 244 to rotate in the reverse direction, driving the ring block 245 to rotate, rising and falling along the trajectory of the reciprocating threaded rod 243, driving a plurality of round head bumps 239 to slide along the inner wall of the first round tube 211. At the same time, driving the first ring frame 237 to slide along the inner wall of the cylinder 210 to scrape off the residual materials on the wall. The ring block 245 moves upward along the trajectory of the reciprocating threaded rod 243, driving the round head bump 239 and the first ring frame 237 back to the original position. The motor 231 drives the round head bump 239 to rotate in the forward direction, pushing the inclined plate 251 to rotate, and sending the scraped materials out from the first round tube 211. Through this mechanism, after the raw materials are poured in, the inner walls of the cylinder 210 and the first round tube 211 can be cleaned without manual cleaning by personnel, effectively improving the cleaning convenience and work efficiency.
