Stone crushing machine for civil engineering

Abstract

The invention discloses a stone crushing machine for civil engineering. The stone crushing machine comprises a platform, wherein a stone crushing cylinder is fixedly arranged on one side of the top end of the platform; a feeding opening is formed in one side of the stone crushing cylinder, and a bearing plate arranged at the feeding opening is installed on the inner wall of the stone crushing cylinder; a second hydraulic machine is arranged at the top of the bearing plate, and one end of a hydraulic rod of the second hydraulic machine is fixedly connected to one end of a stone crushing head. According to the stone crushing machine, by arranging three stages of stone crushing operation, excessively large stones can be crushed and enabled to be smaller step by step through the three stone crushing operations, and the stones are broken one by one; a fourth motor drives a feeding table to move up and down, and when the feeding table rises to a suitable height, the hydraulic rod is controlled to extend by a third hydraulic machine to drive a push plate to push the stones to complete the movement of the stones; and the first hydraulic machine drives a bottom plate to slide inside a sliding groove to realize opening and closing of the stone crushing cylinder, after crushing is completed, the bottom plate is opened to complete discharging, and a conveyor belt receives and conveys the stones.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a rock crusher for civil engineering. Background technique [0002] Stone crushers can be divided into medical stone crushers and mining stone crushers according to major categories. In principle, the mining rock crusher is suitable for crushing a large number of hard rocks in mines. Its typical granite output particle size is ≤40mm, which accounts for 90%. The crushing ratio is large, and the crushed material is in the form of cubic particles. Mining crushing machinery refers to the crushing machinery in which the particle size greater than 3 mm in the discharge accounts for more than 50% of the total discharge. [0003] In the process of implementing civil engineering, it is necessary to crush the larger stones, which can be used for engineering. However, due to the different sizes of the stones, when encountering larger stones in many cases, the traditi...
