Multifunctional engineering machinery based on excavator platform

Abstract

The invention discloses multifunctional engineering machinery based on an excavator platform. The front part of an operation arm of an excavator is hinged with an execution oil cylinder; a boring frame is vertically arranged in front of the operation arm; the middle of the rear surface of the boring frame is provided with a connection plate; the middle of the connection plate is hinged with the front end of the operation arm, while the upper part of the connection plate is hinged with the piston rod stretching end of the execution oil cylinder; the left surface of the boring frame is provided with two guide rails which are arranged vertically side by side; and a sliding plate is connected with the two guide rails and also can slide up and down along the guide rails under traction of a traction device. The multifunctional engineering machinery integrates excavation, stone crushing, boring and sand rock blasting, the cost for purchasing the engineering machinery can be reduced for users, construction is facilitated, and multiple drill rods can be connected together as required to increase boring depth, so that the problem of insufficient boring depth in the prior art is solved well; in addition, the multifunctional engineering machinery can prevent dust from flying in front of the excavator and consequently prevents the sight of an operator from being influenced.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a multifunctional engineering machinery based on an excavator platform. Background technique [0002] With the development of technology and the needs of production, a variety of special engineering machinery has emerged on the market, such as excavators, rotary drilling rigs... Among them, excavators are used for digging soil and gravel, while rotary drilling rigs are only It can be used for drilling and drilling sandstone and shale. At present, there is no construction machinery that integrates the functions of digging, gravel, drilling, and sandstone drilling. This will increase the cost of purchasing construction machinery for users, and will not It is convenient for construction. [0003] In addition, the existing rotary drilling rig mainly relies on the hydraulic cylinder to push and slide to move up and down, and then drives the drill rod on the rock drill to drill ho...

AI Technical Summary

Problems solved by technology

However, during the drilling process, we found that the drilling depth of existing rotary drilling rigs is often not enough to meet the construction requirements

[0004] Finally, during the construction of existing construction machinery, a large amount of dust is often raised in front of the excavator, which will not only seriously affect the operator's sight, but also bring certain safety hazards, and may also cause dust to enter the rotating parts of the construction machinery or shorten the service life of hydraulic lines
