Description

A kind of small size coal rock driling machine

Technical field

The utility model relates to the tunnelling machine technical field, relates in particular to a kind of tunnel pick coal of small-size coal mine or coal rock driling machine of rock drilling of being suitable for.

Background technology

At present, the security incident because small coal mine takes place frequently, blasting coal mining almost is under an embargo; But automaticity height, tunnelling machine safe in utilization, because of its volume big, quality is heavy, and the price height is not suitable for the laneway coal mining of small-size coal mine, known minimole, though it can realize the tunnel pick coal of small-size coal mine, volume is little, and is in light weight, but adopt the single arm type structure mostly, production efficiency is low.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of small size coal rock driling machine is provided, and not only volume is little for it, and is in light weight, and the production efficiency height.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of small size coal rock driling machine, comprise mainframe, the mainframe downside is equipped with crawler unit, the front upper part of mainframe is equipped with the material mole, a shovel board that the material under the pick of material mole can be scooped up is installed in the preceding bottom of mainframe, be provided with two material toggling wheels that can rotate in opposite directions in the shovel board, mainframe is provided with the conveyer of the mass transport that the material toggling wheel can have been dialled to the mainframe rear portion, described material mole comprises and can rotate in opposite directions, by independent first and second heading ends that drive of the first and second driving motors, the first and second driving motors are installed on the head of the first and second driving arms respectively respectively; The front upper part both sides of mainframe are separately installed with first and second Connection Blocks, the afterbody of the first and second driving arms is hinged with first and second Connection Blocks respectively, be respectively equipped with the first and second pitch oil cylinders that the first and second driving arms are swung up and down between the first driving arm and first Connection Block, the second driving arm and second Connection Block, be hinged with transverse link between the first and second driving arms.

After having adopted technique scheme, the shovel board that is arranged on the preceding bottom of mainframe scoops up the material under the pick of material mole, being arranged on two in the shovel board material toggling wheels that can rotate has in opposite directions dialled material, by be arranged on conveyer on the mainframe with mass transport to the mainframe rear portion, thereby realize tunnel pick coal or rock drilling with simple compact structure.The first and second driving motors drive first and second heading ends separately, compare with the single arm type mole, have increased production efficiency; Because first and second heading ends rotate in opposite directions, and the transverse component that produces during driving can be cancelled out each other, make complete machine more steady when work simultaneously.Be hinged with transverse link between the first and second driving arms, strengthened the structural rigidity of material mole, the length of connecting rod can be regulated two relative angles between the driving arm.The first and second pitch oil cylinders swing up and down the first and second driving arms, have increased the driving zone of heading end.

As a kind of improvement, described first and second Connection Blocks are hinged with mainframe respectively, are respectively equipped with the first and second yaw oil cylinders that can make the first and second Connection Block teeters between the mainframe and first and second Connection Blocks.The first and second yaw oil cylinders can make the first and second Connection Block teeters, and first and second heading ends are done the synchronous horizontal swing under the drive of the first and second driving arms, have increased its driving zone.
