Slug production device for brick-making machines
 The invention herein relates to a kind of slug production device for brick-making machines, specifically referring to a kind of slug production device that is mainly comprised of a raw brick mixture filler trough and a vacuum trough, below which are the the parallel and horizontal members of two pressure tubes and two forming tubes, and positioned at the rear of the two pressure tubes and the two forming tubes are a pair of pressure mechanisms and, furthermore, at the bottom section of the raw brick mixture filler trough and the vacuum trough is a swing-type aggregate crushing mechanism such that after the raw brick mixture is loaded into the filler trough, the raw brick mixture is conveyed precisely into the pressure tubes and the pressure mechanism pistons at the rear of the two pressure tubes operate in a reciprocal movement to convey the raw brick material slugs into the vacuum trough then the raw brick material aggregate conveyed into the vacuum trough are guided into the forming tubes by the pressure mechanism and, furthermore, subjected to an equal forming and output pressure by the reciprocal operation of the pistons in the pressure mechanism at the rear of the forming tubes, which enables the invention herein to effectively achieve increased working efficiency and consistent slug quality.
