Construction powder material mixing and crushing device

Abstract

The invention discloses a construction powder material mixing and crushing device. The construction powder material mixing and crushing device comprises a machine frame and a base. The machine frame comprises a primary operation chamber, a secondary operation chamber and a shock absorbing seat. The primary operation chamber is divided into a rolling chamber and a screening chamber. The rolling chamber is located on the left side of the screening chamber. A feeding hopper is mounted at the bottom end of the screening chamber. A first filtering screen is arranged in the screening chamber. The screening chamber communicates with a first material conveying port formed in the upper portion of the rolling chamber. The bottom end of the first filtering screen is located on the upper portion of the first material conveying port. A first rolling roller and a second rolling roller are transversely arranged in the rolling chamber in parallel and fixed in the rolling chamber through a first roller shaft and a second roller shaft correspondingly. Gravels or stone particles are screened, filtered, ground and crushed through a filtering screen mechanism, and abrasion or transmission obstruction to operation equipment is prevented.

Description

technical field [0001] The invention relates to construction equipment, in particular to a mixing and crushing device for construction powder materials. Background technique [0002] Construction engineering refers to the engineering entity formed through the construction of various housing buildings and their ancillary facilities and the installation activities of supporting lines, pipelines and equipment. Among them, "housing construction" refers to projects that have roofs, beams, walls, foundations, and can form internal spaces to meet people's needs for production, living, learning, and public activities. [0003] In construction operations, it is often necessary to use material crushing devices to crush materials. Most of the existing crushing devices have simple structures, single functions, poor crushing effects, low work efficiency, and cannot effectively absorb shocks, which cannot meet the needs of modern production crushing. At the same time, building materials ...

Problems solved by technology

[0003] In construction operations, it is often necessary to use material crushing devices to crush materials. Most of the existing crushing devices have simple structures, single functions, poor crushing effects, low work efficiency, and cannot effectively absorb shocks, which cannot meet the needs of modern production crushing. At the same time, building materials often have the problem of agglomeration, and at the same time, large gravel or even stones are mixed, which often cause wear and tear on the mixing and crushing equipment, and even engage the transmission parts of the equipment.
