Description

Technical Field

[0001] The invention relates to the technical field of block forming equipment, in particular to a lifting brick connecting machine and a low-height brick production process. Background Art

[0002] A block-making machine produces new wall blocks by mixing materials such as sand, gravel, and fly ash with a small amount of cement. These new concrete blocks feature high strength, easy masonry, smooth wall surfaces, and high construction efficiency. A block-making machine typically consists of a main frame, a vibrating table, a feed cart, an upper press, and a feed cart. During brick-making, raw materials enter the feed cart through a hopper. The cart evenly transfers the raw materials to the mold frame on the vibrating table. After the vibrating table forms the blocks, a brick-handling machine transports the finished blocks and pallets from the vibrating table to the next stage. When producing taller blocks, the bottom of the feed cart is located above the mold. This vibration and compression creates a lower height than in the mold, resulting in greater compression and allowing the blocks to be easily transferred from the bottom of the feed machine to the next stage. However, when producing shorter blocks, the compression is less, and the height of the concrete blocks is not significantly reduced in the mold. This can cause the concrete blocks to collide with the bottom of the feed machine as they pass through the machine, affecting product quality and potentially causing production safety accidents.
