Stone-crushing concrete preparation device for buildings

Abstract

The invention discloses a stone crushing concrete preparation device for construction, which comprises a base, a left support plate and a right support plate are respectively arranged on the left and right sides of the base; the left support plate and the right support plate are fixed by a bracket There is a crushing box, and the bottom of the crushing box is fixed with an extruding plate; the first rotating shaft is also connected with marbles through elastic wires, and the marbles are located below the crushing box; the base is also provided with a mixing bucket through a bracket. There is a material receiving funnel on the left side of the top of the mixing barrel; a third rotating shaft is connected to the rotating shaft in the mixing barrel, and a spiral blade is installed on the third rotating shaft. The left end of the third rotating shaft passes through the left side wall of the mixing barrel, and the left end of the third rotating shaft It is connected with the right end of the first rotating shaft through a universal joint. The invention uses marbles to knock the bottom of the crushing box to prevent adhesion and blockage; the stone particles after screening are directly entered into the mixing tank for concrete preparation without manual control, and the processing efficiency is effectively improved.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a device for preparing stone crushed concrete for construction. Background technique [0002] With the improvement of urbanization, new buildings are built every day. The construction of buildings is inseparable from concrete. Concrete preparation requires the use of stones, and some stones are too large to be directly used for construction. The stone is crushed to facilitate the utilization of the stone. [0003] The crushing efficiency of the general crushing mechanism is not high, and the stones cannot be screened during crushing. After crushing, there are still many stones that do not meet the requirements and cannot be used directly. A separate concrete mixing device is used for concrete preparation, which will lead to low construction efficiency and is very inconvenient. Contents of the invention [0004] The object of the present invention is to provide a device f...
