Energy-saving and environment-friendly aggregate centralized feeding system

Abstract

The invention discloses an energy-saving and environment-friendly aggregate centralized feeding system, and belongs to the technical field of concrete production equipment. The energy-saving and environment-friendly aggregate centralized feeding system comprises a rack and a motor. The rack is rotationally connected with an obliquely-arranged screening cylinder. The screening cylinder comprises a driving shaft and a plurality of screening rings. A screening gap is formed between every two adjacent screening rings. The driving shaft is provided with connecting rings along the axis of the driving shaft, wherein the number of the connecting rings is matched with that of the screening rings. A plurality of screening rods are fixedly connected between each connecting ring and the corresponding screening ring. The motor is rotationally connected with the driving shaft. The rack is further fixedly provided with an air cylinder. The movable end of the air cylinder is fixedly connected with an arc-shaped connecting plate. The connecting plate is fixedly connected with a plurality of extrusion blocks stretching into the corresponding screening gaps. Each extrusion block comprises a thin end and a thick end, wherein the thin end is close to the outer wall of the corresponding screening ring, and the thick end is close to the corresponding screening rod after passing through the corresponding screening gap. According to the scheme, blocked aggregate is dredged through the extrusion blocks, and the dredging effect is better.

Description

technical field [0001] The invention relates to the technical field of concrete production equipment, in particular to an energy-saving and environment-friendly centralized aggregate feeding system. Background technique [0002] Concrete aggregate refers to the granular loose material that acts as a skeleton or filling in concrete. It is divided into coarse aggregate and fine aggregate. Coarse aggregate refers to pebbles, crushed stones, etc., and fine aggregate refers to natural sand and artificial sand. Concrete aggregates need to be screened before loading. The purpose of screening is to realize the classification of concrete aggregates, so as to prevent large aggregates from affecting the quality of concrete. [0003] Such as a screening device for concrete aggregates with the publication number CN213996655U, comprising a mounting frame, on which a mounting rod is obliquely arranged, and the mounting rod is installed on the mounting frame by rotating along its own circum...

Problems solved by technology

[0004] In the above-mentioned patent, the extrusion rod is located in the screen cylinder and is in sliding contact with the screen rod, and the blocked aggregate is extruded out through the reverse rotation of the extrusion rod. However, because the number of extrusion rods cannot be set too much, too many On the contrary, the extrusion rod will prevent the aggregate from being screened through the sieve rod. In addition, the extrusion rod is blocked by the sieve rod and cannot completely squeeze out the clogged aggregate, resulting in poor dredging effect. As far as the aggregate between the rods is concerned, the extrusion rod cannot touch the aggregate and cannot be squeezed and dredged
