Sand and gravel crushing device for construction engineering

Abstract

The invention discloses a sandstone crushing device for construction engineering, which comprises a treatment box and a support seat, the bottom of the treatment box is fixedly connected to the top of the support seat, and a dust removal mechanism is fixedly connected to the right side of the top of the treatment box. A feed hopper is provided on the left side of the top of the processing box, and the left side of the top of the inner cavity of the processing box is connected to the first feeding plate through a connecting rod. A curved frame is fixedly connected to the lower part of the output end of a feeding plate. The invention relates to the technical field of sand and gravel crushing. The sand and gravel crushing device used in construction projects uses the first conveying plate to lengthen the conveying space to reduce the area of ​​dust generation, and then directly sets multiple grinding processes in the treatment box, and cooperates with the dust removal mechanism for adsorption treatment to effectively reduce the crushed dust. It can filter out the sand and gravel that is less than the standard quality in the crushing process, save the follow-up process, and effectively ensure the processing quality of the device.

Description

technical field [0001] The invention relates to the technical field of sand and gravel crushing, in particular to a sand and gravel crushing device for construction engineering. Background technique [0002] Sand refers to the loose mixture of sand and gravel. In geology, mineral or rock particles with a particle size of 0.074-2mm are called sand, and those with a particle size greater than 2mm are called gravel or breccia. If there are many gravels in the sand gravel, known as gravel. In daily life, some people also refer to sandstone as sandstone. At present, with the continuous development of my country's economic construction and the acceleration of urbanization, my country's urban infrastructure and real estate development have developed rapidly, which has promoted the rapid increase in concrete production. improve. Cement and sand are the main raw materials for making concrete. Sand and gravel need a certain proportion of size when making concrete, and large-scale sa...
