Description

Technical Field

[0001] This utility model relates to the field of recycled concrete block manufacturing technology, specifically to a recycled concrete block manufacturing equipment. Background Technology

[0002] Masonry blocks are man-made building materials used for construction, a new type of wall material. They are block-shaped building products larger than clay bricks, and are mostly rectangular hexahedrons in shape. Chinese patent CN215038465U discloses a recycled concrete block manufacturing equipment, including a feeding hopper. A rotary motor is fixedly connected to the top of the feeding hopper, and the output shaft of the rotary motor is fixedly connected to a rotating shaft via a coupling. A stirring blade is fixedly connected to the outer wall of the rotating shaft. A feed hopper is fixedly connected to the top of the feeding hopper, and a discharge port is opened at the bottom of the feeding hopper. A conveying hopper is fixedly connected to the bottom of the feeding hopper, and a discharge port is opened at the bottom of the conveying hopper. A support plate is fixedly connected to one side of the conveying hopper. This recycled concrete block manufacturing equipment can accelerate the removal of air bubbles from the concrete block slurry, resulting in stronger concrete blocks after molding. It avoids the problem of poor quality in general recycled concrete block manufacturing equipment that does not remove air bubbles from the static concrete, thus improving the quality of the finished blocks. However, it still has the following drawbacks: because the discharge port, conveying hopper, and outlet are not closed, the raw material mixing time is short, resulting in insufficient mixing of raw materials, which can lead to internal delamination and cracking of the bricks, affecting the strength and service life of the bricks. Therefore, we propose a recycled concrete block manufacturing equipment to solve this problem. Utility Model Content
