Abstract

The invention belongs to the technical field of building material crushing equipment and discloses a building sandstone crushing apparatus. The building sandstone crushing apparatus comprises a rack arranged at one side close to a discharge port. The rack is provided with a transport barrel and a screening frame positioned below the transport barrel. An inlet pipe is arranged between the transportbarrel and the discharge port. A feeding barrel is rotatably connected inside the transport barrel. External diameter of the feeding barrel is equal to internal diameter of the transport barrel. Oneend of the feeding barrel is closed, and the other end is opened. The closed end of the feeding barrel is positioned outside the transport barrel. The rack is provided with a driving part which drivesthe feeding barrel to rotate. A discharge chute is arranged inside the feeding barrel. The bottom of the transport barrel is provided with two feed openings which match the discharge chute. The two feed openings are respectively positioned above two ends of the screening frame. Several elastic parts are arranged between the bottom of the screening frame and the rack. Two sides of the screening frame below the two feed openings are provided with material receiving openings. According to the invention, the problem that the cost of sandstone crushing is high because two sets of devices are needed for crushing and screening of sandstone in the prior art is solved.

Description

technical field [0001] The invention belongs to the field of building material crushing equipment, and in particular relates to a building sandstone crushing device. Background technique [0002] Architecture is the general term for buildings and structures. It is an artificial environment created by people using material and technical means and certain scientific laws, Feng Shui concepts and aesthetic principles to meet the needs of social life. Architecture is a space for people to live and use that people use building materials such as mud, bricks, tiles, sand, stones, and wood. [0003] Sand refers to the loose mixture of sand and gravel, which is the most basic and one of the most traditional Chinese medicine production raw materials in construction. However, not all sizes of sand and gravel can be used in construction projects. Before use, the sand and gravel need to be crushed so that the sand and gravel meet the particle size requirements before use. [0004] The e...
