The first position sensor and the second position sensor are both encoders, and the two encoders are both in radio connection with the controller. An encoder is a rotary sensor that functions to convert an angular or linear displacement into an electrical signal, where it is used to detect the angular displacement of an access door or security fence and convert it into an electrical signal that is sent to a controller. The encoder can send an open state signal or a closed state signal, and in particular, the first position sensor can send an open state signal or a closed state signal of the access door, and the second position sensor can send an open state signal or a closed state signal of the security fence. In this embodiment, the encoder may be obtained directly by a commercially available purchase.
Further, the above structure further includes an operation switch, and the operation switch is connected to the controller and configured to send a control request signal. In this embodiment, the controller is used to control the position actuator 3, the lock actuator 6 and the movement actuator 9 connected thereto, and the operation switch is used to send a request signal to the controller, so that the controller can send out a corresponding control signal. The request signal may be an opening request, a closing request or a static request of the access door, or may be a locking request of the security fence.
Further, the safety fence 4 is a grating fence, and the grating part of the grating fence is an unobstructed window; the dimensions of the safety fence 4 correspond to the dimensions of the access opening. Further, the access hole security fence 4 with access door 1 all is the rectangle form, just security fence 4 with access door 1 can with the access hole adaptation.
Further, the locking actuator 6 is an electromagnetic switch, the purpose of which is to prevent the operator from opening the safety fence while the turning shaft is still moving. The electromagnetic switch locks or unlocks the security fence in the closed position when receiving a command signal from the controller. The command signal may be a lock signal or an unlock signal.
Furthermore, the position actuator 3 is a hydraulic cylinder, a base of the hydraulic cylinder is installed on the frame, and a piston rod is connected with the side edge of the access door 1. Of course, the position actuator 3 may also be another telescopic control device for driving the access door 1 to switch between the closed position and the open position when receiving a command signal from the controller. The access door is driven from a closed position to an open position upon receiving a command signal from the controller, which may be closed or open.
Further, the motion actuator 9 is a hydraulic motor or an electric motor, and is used for driving the rotating shaft 7 of the crusher 14 to rotate or stop when receiving a command signal of a controller. The command signal may be a working movement (rotation at a rotational speed according to the working state), a speed-limiting movement or a static signal. In particular, the number of motion actuators 9 depends on the number of rotary shafts 7 in the crusher 14.
Furthermore, the frame is enclosed by the polylith mounting panel and closes and forms, one of them is located to the access hole on the mounting panel.
Further, the controller is connected with the position actuator 3, the locking actuator 6, the first position sensor 2, the second position sensor 5, the movement actuator 9 and the operation switch through wireless signals.
In the above structure, the controller is preferably a PLC controller, and the PLC controller is a digital electronic device with a microprocessor, and is a digital logic controller for automatic control, and can load the control instruction into the memory at any time for storage and execution. In this embodiment, the device is mainly used for acquiring signals of the first position sensor 2, the second position sensor 5 and the motion sensor 8, and sending instruction signals to the actuator 3, the locking actuator 6 and the motion actuator 9 in turn to complete corresponding functions. The PLC controller may be obtained directly from a commercially available purchase and, after connection, reset its functions so that it can perform the functions described above.
Further, the utility model also discloses a method of use of above-mentioned feeding hopper for breaker 14:
install above-mentioned structure equipment feeding hopper at first to make the signal operation between each part unobstructed, then carry out different controls according to the use scene of difference, it is specific:
Operating and observing states: the controller sends a designated signal to the position actuator 3 to enable the position actuator 3 to execute an opening instruction, and further enable the access door 1 to be opened; by manually operating the safety rail 4 and the locking actuator 6, the safety rail 4 is closed and position-locked by the locking actuator 6. Then, the control system obtains that the locking actuator 6 is in a locking state through a state detector in the locking actuator 6, obtains that the safety fence 4 is in a closed state through the second position sensor 5, and instructs the movement actuator 9 to operate, so that the crusher 14 operates normally, and observes the operating conditions in the crusher 14 through a grid window of the safety fence 4.
Maintenance state: the controller firstly sends a closing command signal to the motion actuator 9 to enable the rotating shaft 7 in the crusher 14 to be in a stalling state; then, the positions of the access door 1 and the safety fence 4 are obtained through the first position sensor 2 and the second position sensor 5, and a designated signal is sent to the position actuator 3 when the access door 1 is closed, so that the position actuator 3 executes an opening instruction, and the access door 1 is opened; and then the maintenance is carried out. In the process, the movement actuator 9 is always closed, so that the rotary shaft 7 can only be rotated manually.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
