Cutting part and heading machine

Technical Field

The utility model relates to a heavily be good at equipment technical field, especially relate to a cutting units and entry driving machine.

Background

At present, the cutting part of the traditional heading machine at home and abroad adopts a motor to drive a gear set transmission, so that a cutting head assembled on a main shaft is driven to rotate, cutting teeth arranged on the cutting head extrude and crush rocks through rotary motion, and the rock stratum heading function is realized.

The traditional driving mode is used for many years, and firstly, the transmission of the gear set transmission is heavy in load and large in noise; energy is converted and transmitted through a gear set transmission, so that the efficiency is low and the energy consumption is high; thirdly, the lubrication requirement on the gear set transmission is high, and the gear is often damaged due to poor lubrication; and fourthly, the overload impact resistance of the gears in the gear set transmission is not strong, once hard rocks (which often occur when faults occur in actual production) are clamped in broken rock stratums, a control system does not react timely, so that the gear set bears impact overload, the gear surface of the gear is damaged slightly to cause unstable operation and increased noise, and the gear is broken seriously to cause production interruption. And energy is converted and transmitted through a gear set, and due to the limitation of installation space, the working capacity of a gear set transmission is limited, so that the peak torque force of the cutting head is limited, and harder rock cannot be crushed (generally, granite cannot be directly crushed).

SUMMERY OF THE UTILITY MODEL

The embodiment of the utility model provides a technical problem that will solve provides a cutting units and entry driving machine to the messenger has reduced material, oil and energy consumption and has promoted the reliability.

In order to solve the technical problem, the embodiment of the utility model provides a cutting unit is proposed, including the cutterhead, the main shaft, motor and pipy main part, the main shaft is rotatable to be located in the main part, still include the shaft coupling, integral key shaft and spline housing, in the main part was located to the integral key shaft, the cutterhead was located the one end of main part and was connected with main shaft one end, the other end of main part is located to the motor, the output shaft of motor passes through the shaft coupling and is connected with the spline shaft, the spline housing is located on the integral key shaft, the other end of main shaft is connected to the spline housing, the motor passes through the rotation of integral.

Further, the main shaft, the coupler, the spline shaft and the spline housing are integrally formed.

Further, shaft coupling, integral key shaft and spline housing integrated into one piece.

Further, the motor is a high torque motor.

Correspondingly, the embodiment of the utility model provides a still provide a heading machine, including foretell cutting units.

The utility model has the advantages that: the utility model discloses by the rotatory broken doing work of motor direct drive cutterhead, simplified the drive structure of entry driving machine cutting part, the contact friction of no gear group derailleur has improved cutterhead actuating mechanism's reliability, and energy conversion is efficient, and torsion is bigger, and the quiet noise of operation is little, has more stopped the defect that leads to the gear to collapse when breaking stereoplasm fault, and then has reduced material, oil and energy consumption.
