The signal of actuator is inputted by controller, and the actual displacement of Electric Actuator can be passed to controller in real time by displacement sensor,
The closed-loop control of knife physical location so that guarantee is backbreak.Pass through closed-loop control, the reality for the knife that can backbreak with Real-time Feedback and amendment
Stroke, and final complete stability achievees the purpose that accurately control, to help to improve system in the setting value of operating personnel
Precision and stability.Specifically, controller is converted to output signal by the control signal of input and is transferred to servo motor, servo
Motor controls the physical location of Electric Actuator according to the input signal.Meanwhile controller passes through the Electric Actuator that receives
Actual displacement, adjust output parameter in time, to form closed-loop control, the final precision for improving cutter position of backbreaking and accurate
Property.
Further, in one preferred embodiment, Electric Actuator is connect with knife of backbreaking by link mechanism.It is logical
Link mechanism is crossed, it can be according to real space come the installation site of arrange to backbreak knife and Electric Actuator.Also, in some determinations
In the case of, a small Electric Actuator can be amplified using lever principle by link mechanism and be effectively outputed to knife of backbreaking
On active force.
Specifically, in one preferred embodiment, Electric Actuator uses gear-driven form.Electric Actuator is adopted
Make the structure of Electric Actuator simple with gear-driven mode, and easily realizes the straight line fortune of Electric Actuator
It is dynamic, to drive knife of backbreaking for linear motion.
Specifically, in another preferred embodiment, Electric Actuator uses Worm Wheel System form.Further
Ground, in one preferred embodiment, controller can control Electric Actuator according to determining sequence action so that super
It digs knife and realizes forming movement.It is controlled by the programmable controller of standard, Electric Actuator can realize complicated motion sequence
Action, to realize the profile modeling function for knife of backbreaking.
In one preferred embodiment, Electric Actuator includes several.By multiple Electric Actuator, on the one hand
The power output for knife of backbreaking can be improved, on the other hand, in determining space, by single motor actuator installation space institute
Limit can only control a knife of backbreaking by multiple small Electric Actuator.
Development machine according to a second aspect of the present invention, including shell, and the pick as described above in shell
It backbreaks knife control mechanism into machine.
Compared with prior art, the advantage of the invention is that：It is simple and compact for structure, installation space is small, at low cost, and avoid
System low-response, cannot adjust knife stroke of backbreaking so as to cause deficient digging or the problem of cross digging in time, Electric Actuator it is entire
Life cycle need not safeguard that Electric Actuator repeatable accuracy is high.
Description of the drawings
The invention will be described in more detail below based on embodiments and refering to the accompanying drawings.Wherein：
The development machine that Fig. 1 schematically illustrates the embodiment of the present invention is backbreak knife control mechanism；
The development machine that Fig. 2 schematically illustrates the embodiment of the present invention is backbreak another structure of knife control mechanism.
In the accompanying drawings, identical component uses identical reference numeral.Attached drawing is not drawn according to actual ratio.
Specific implementation mode
Below in conjunction with the drawings and specific embodiments, invention is further described in detail, but does not therefore limit this
The protection domain of invention.
The development machine that Fig. 1 schematically illustrates the embodiment of the present invention is backbreak knife control mechanism 10.Fig. 2 schematically illustrates this
The development machine of inventive embodiments is backbreak another structure of knife control mechanism 10.
As depicted in figs. 1 and 2, the development machine of the embodiment of the present invention is backbreak knife control mechanism 10, including controller 1, electronic
Actuator 2 and knife 3 of backbreaking, Electric Actuator 2 are connect with controller 1 and knife 3 of backbreaking respectively.The development machine of the embodiment of the present invention is super
Knife control mechanism is dug, hydraulic cylinder in the prior art is substituted using Electric Actuator, and hydraulic power unit, liquid need not be configured
The system elements such as pressure control valve, so that development machine is backbreak, knife control mechanism is simple and compact for structure, correspondingly, can to dig
Into machine backbreak knife control mechanism installation space it is small and save manufacturing cost.In addition, since Electric Actuator passes through control
The signal of device input adjusts the speed control extended and retracted and backbreaks the actual displacement of knife, can avoid backbreaking in the prior art
Knife is controlled by oil cylinder, and oil cylinder causes system low-response by solenoid valve control, cannot adjust knife stroke of backbreaking in time to lead
The problem of causing to owe to dig or cross digging.Further, in one preferred embodiment, as shown in Fig. 2, Electric Actuator 2 with it is super
Knife 3 is dug to connect by link mechanism 4.It, can be according to real space come arrange to backbreak knife and Electric Actuator by link mechanism
Installation site.Also, under some certain situations, a small Electric Actuator utilizes lever original by link mechanism
Reason, can amplify the active force for being effectively outputed to backbreak on knife.Specifically, in one preferred embodiment, electronic execution

The speed of device is steady and continuously adjustable.In addition, the signal of Electric Actuator is inputted by controller, displacement sensor can will be electronic
The actual displacement of actuator is passed to controller in real time, the closed-loop control of knife physical location so that guarantee is backbreak.Pass through closed loop control
System, the traveled distance for the knife that can be backbreak with Real-time Feedback and amendment, and final complete stability reaches essence in the setting value of operating personnel
The purpose really controlled, to help to improve the precision and stability of system.Specifically, the control signal that controller passes through input
It is converted to output signal and is transferred to servo motor, servo motor controls the physical location of Electric Actuator according to the input signal.
Meanwhile controller adjusts output parameter in time by the actual displacement of the Electric Actuator received, to form closed loop control
System, the final precision and accuracy for improving cutter position of backbreaking.
Further, in one preferred embodiment, controller 1 can control Electric Actuator 2 according to determining sequence
Row act so that knife 3 of backbreaking realizes forming movement.It is controlled by the programmable controller of standard, Electric Actuator can be real
Existing complicated motion sequence action, to realize the profile modeling function for knife of backbreaking.
Specifically, in one preferred embodiment, Electric Actuator 2 uses gear-driven form.Electric Actuator
Make the structure of Electric Actuator simple using gear-driven mode, and easily realizes the straight line of Electric Actuator
Movement, to drive knife of backbreaking for linear motion.Specifically, in another preferred embodiment, Electric Actuator 2 uses
Worm Wheel System form.In one preferred embodiment, Electric Actuator includes several.Pass through multiple electronic execution
On the one hand device can improve the power output for knife of backbreaking, on the other hand, in determining space, since single motor actuator is pacified
Dress space is limited, and can only control a knife of backbreaking by multiple small Electric Actuator.
The development machine of second aspect of the present invention embodiment, including shell, and it is as described above in shell
