Stone-crushing concrete preparation device for buildings

Abstract

The invention discloses a stone-crushing concrete preparation device for buildings. The stone-crushing concrete preparation device comprises a base, wherein a left supporting plate and a right supporting plate are correspondingly arranged on the left side and the right side of the base; a crushing box is fixedly arranged between the left supporting plate and the right supporting plate through a support; an extruding plate is fixedly arranged at the inner bottom of the crushing box; a marble is connected to a first rotating shaft through a snapline and positioned below the crushing box; an agitator is obliquely arranged on the base through a support, and a receiving hopper is arranged on the left side of the top of the agitator; a third rotating shaft is rotationally connected to the interior of the agitator; a spiral blade is mounted on the third rotating shaft; and the left end of the third rotating shaft penetrates the left side wall of the agitator and is connected with the right end of the first rotating shaft through a universal coupler. According to the stone-crushing concrete preparation device, the bottom of the crushing box is knocked by the marble, so that adhesion blockage is prevented; and screened stone particles directly enter the agitator to prepare concrete without manual control, so that 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...
