Problems solved by technology

[0005] The present invention provides a mechanical rock-breaking device for road construction, one of the purposes of which is to have the characteristics of replacing the crushing gear separately, so as to solve the impact of rocks, which will cause bending damage on the surface of the crushing teeth and internal connections. It is time-consuming and labor-intensive to disassemble the entire gear piece when replacing it; another purpose is to solve the problem that the internal particles of dust will be relatively large, and a large number of them will adhere to the surface of the filter screen, which will block one side of the filter screen So as to reduce the problem of dust filtering effect, in order to achieve the effect of reducing dust for relatively large particles in dust, reducing the flow of large particles, and filtering fine dust

Abstract

The invention discloses a mechanical rock breaking device for road construction, and relates to the technical field of mechanical rock breaking, the mechanical rock breaking device for road construction comprises a road construction rock breaking device, the road construction rock breaking device comprises a supporting column, and the top of the supporting column is detachably provided with a top head fixer; an anti-shaking clamping layer is detachably installed on the inner side surface of the top fixing device, and a rock breaking device is detachably installed on the inner surface of the anti-shaking clamping layer. When rocks enter the rock breaking device, the rocks are broken into small blocks in cooperation with a breaking wheel, then the small blocks of rocks are smashed through a rotary smashing device during rotation, guiding is conducted through a material guiding inclined plate, dust in the rocks is sucked through an air draft dust suction machine, and the rock breaking device has the beneficial effects that large rocks are preliminarily broken and smashed; and the problems that rock which is high in toughness and not prone to cracking cannot be effectively crushed, and rock breaking work is difficult to guarantee are solved, and the effects of preliminarily crushing and re-crushing large rock are achieved.

Description

technical field [0001] The invention relates to the technical field of mechanical rock breaking, in particular to a mechanical rock breaking device for road construction. Background technique [0002] Road is an infrastructure for various trackless vehicles and pedestrians. According to its use characteristics, it can be divided into highways, urban roads, country roads, factory and mine roads, forestry roads, examination roads, competition roads, automobile test roads, workshop passages and school roads, etc. In the process of road construction, in order to improve the safe bearing capacity of the road, crushed rocks are usually laid in the road as the subgrade of the road. There are following problems at prior art: [0003] 1. When the existing mechanical rock-breaking device for road construction is in use, it is difficult to form a fixed state between the rock-breaking device and the rock. Because some rocks are relatively large in size, the rock-breaking device placed ...
