24, the pressure sensor 24 is used to detect the pressure values inside oil cylinder 19, the output end output characterization institute of pressure sensor 24
State the pressure signal of pressure values；Second input terminal of the controller 20 is connect with the output end of the pressure sensor 24, institute
It states after controller 20 receives the pressure signal, if the pressure values that the pressure signal is characterized are greater than setting pressure
Value, then output reset signal, the second end of the controller 20 then export stop signal to the first output end of the controller 20.
The setting pressure values are specially the highest pressure that oil cylinder 19 is able to bear, and can so protect oil cylinder 19, avoid the excessively high damage of oil pressure
Bad oil cylinder 19.
In some embodiments, above scheme further includes camera 25 and display screen 26, and the camera 25 is set
It is placed on the hydraulic support at 101 tail of drag conveyor, hydraulic support can protect camera 25 to avoid being dropped
Coal cinder smashes.The camera 25 is used to shoot the image at 101 tail of drag conveyor, and the output end of camera 25 exports packet
Image information containing the image.The third input terminal of the controller 20 is connect with the output end of the camera 25, described
Controller 20, which receives, to be controlled the display screen 26 after the image information and shows the image, the equally setting of display screen 26
In the inside of hydraulic support, to be checked for the staff for being located at internal stent work.It is also set up in the inside of the bracket
There is electric-controlled switch, when the electric-controlled switch is closed, the electric-controlled switch exports enabling signal；4th input of the controller 20
End is connect with the electric-controlled switch, and after the controller 20 receives the pneumatic signal, the controller 20 just exports institute
State forward signal and the open signal.Specifically, one end of the electric-controlled switch can be connect with power supply, electric-controlled switch
The other end is connect with the 4th input terminal of the controller 20, when electric-controlled switch closure, the 4th of the controller 20 the
The current potential of input terminal just generates variation, i.e. electric-controlled switch exports enabling signal, and controller 20 is promoted to start oil cylinder 19 and electronic rolling
Cylinder 5.The setting of the electric-controlled switch, when tail coal is excessive, staff can manually boot clear tail coal device, to clear up tail as early as possible
Coal.In addition, the starting of tail coal device, is also may rely on camera 25 and controller 20 starts, i.e., it is defeated to receive scraper plate for controller 20
After sending the image at 101 tail of machine, the standard video with storage is compared, the image at 101 tail of drag conveyor with
There are when a certain proportion of coincidence for standard video, then it is assumed that tail coal is excessive, and controller 20 just exports forward signal and unlatching at this time
Signal.Microcontroller common on the market, PLC etc. can be used in the controller 20.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution

The first input end of the controller is connect with the output end of institute's displacement sensors, and the controller receives the length
After spending signal, if the extended length value that the length signals are characterized is equal to or more than the first given threshold, the controller
First output end then exports reverse signal, and the second output terminal of the controller then exports stop signal；If the length signals
The extended length value characterized is equal to or less than the second given threshold, and the first output end of the controller then exports reset letter
Number；
The solenoid valve block receives counteragent after the reverse signal, connects the oil outlet of the pumping plant and the oil cylinder
It is logical, the oil cylinder retraction；The solenoid valve block resets after receiving the reset signal, blocks the pumping plant and the oil cylinder
Connection, the oil cylinder stop flexible；
The contactor disconnects after receiving the stop signal, and the power end of the motorized roller and the power supply are disconnected
It opens, the motorized roller stops rolling.
8. the clear tail coal device of scraper conveyor tail according to claim 7, which is characterized in that further include pressure sensing
Device；
The pressure sensor is set to the inside of the oil cylinder, for detecting the pressure values inside the oil cylinder, output end
Output characterizes the pressure signal of the pressure values；
Second input terminal of the controller is connect with the output end of the pressure sensor, and the controller receives the pressure
After strong signal, if the pressure values that the pressure signal is characterized are greater than setting pressure values, the first output of the controller
Then output reset signal, the second output terminal of the controller then export stop signal at end.
9. the clear tail coal device of scraper conveyor tail according to claim 8, which is characterized in that further include camera and aobvious
Display screen；
The camera is set on the hydraulic support at the scraper conveyor tail, for shooting the drag conveyor machine
Image at tail, output end output include the image information of the image；
The third input terminal of the controller is connect with the output end of the camera, and the controller receives the image letter
The display screen is controlled after breath shows that the image, the display screen are set to the inside of the hydraulic support.
10. the clear tail coal device of scraper conveyor tail according to claim 9, which is characterized in that further include electric-controlled switch；
The electric-controlled switch is set to the inside of the hydraulic support, and when electric-controlled switch closure, the electric-controlled switch is defeated
Enabling signal out；
4th input terminal of the controller is connect with the electric-controlled switch, when the controller receives the enabling signal
Afterwards, the controller just exports the forward signal and the open signal.
