Abstract
The utility model relates to an automatic oiling device of an excavator, which comprises an oiling pump arranged between a fuel tank and an oil storage barrel; the control signal input end of the oiling pump is connected with the signal output end of a controller; a float type liquid level sensor is arranged on the top of the fuel tank; the signal output end of the float type liquid level sensor is connected with the signal input end of the controller; and the controller is used for receiving a liquid level signal transmitted by the float type liquid level sensor and controlling the oiling pump to stop oiling. The automatic oiling device saves labor, and simultaneously can accurately control the oiling amount of the fuel tank.
Description
Technical field
The utility model relates to a kind of refueling device, relates in particular to a kind of device that excavator can be controlled gasoline pump automatically that is used for.
Background technology
The oiling of excavator at present all is now oil storage barrel and fuel tank to be connected by gasoline pump by artificial, starting gasoline pump again refuels in fuel tank, in refueling process, need the special messenger to guard, constantly notice whether the oil in the fuel tank is filled it up with, if guard's carelessness, fuel tank will overflow after filling it up with oil.This oiling mode is labor intensive but also the very difficult amount of refueling of controlling not only.
The utility model content
The utility model has been designed and developed out a kind of saving manpower at the deficiencies in the prior art, can accurately control the excavator automatic fuelling device of fuel tank volume read-out simultaneously.
The utility model is achieved through the following technical solutions:
A kind of excavator automatic fuelling device is included between fuel tank and the oil storage barrel and is provided with gasoline pump, and the control signal input of described gasoline pump is connected with the signal output part of controller; At described fuel tank top the float-type liquid level sensor is installed, the signal output part of float-type liquid level sensor is connected with the signal input part of controller; The liquid level signal that described controller transmits in order to reception float-type liquid level sensor, and the control gasoline pump stops to refuel.
A kind of excavator automatic fuelling device is provided with gauge tap in the described controller, and the signal output part of gauge tap is connected with protective device, and the signal output part of protective device is connected with the relay signal input; Relay one end signal output is connected with the audible-visual annunciator signal input part, and the other end is connected with I/O interactive interfacing formula; The signal output part of described float-type liquid level sensor is connected by the I/O Interface and Controler respectively with the signal input part of gasoline pump.
The utility model detects the fueling state of fuel tank by a liquid-level switch that is contained in fuel tank top float-type, when the fuel liquid level of self-service petrol pump injection fuel tank reaches predeterminated position, controller can cut off the power supply current supply circuit of gasoline pump automatically, carry out the sound and light alarm prompting simultaneously, save manpower, simplify refueling process, guarantee the effect of refueling.
Description of drawings
Fig. 1 is the device feature structural representation.
Fig. 2 is a device middle controller structural representation block diagram.
The specific embodiment
Shown in accompanying drawing 1.Be provided with gasoline pump 3 between fuel tank 1 and the oil storage barrel 4, the control signal input of gasoline pump 3 is connected with the signal output part of controller 5 in the utility model; At fuel tank 1 top float-type liquid level sensor 2 is installed, the signal output part of float-type liquid level sensor 2 is connected with the signal input part of controller 5; The liquid level signal that controller 5 transmits in order to reception liquid level sensor 2, and control gasoline pump 3 stops to refuel.Shown in accompanying drawing 2.Be provided with gauge tap 6 in the controller 5, the signal output part of gauge tap 6 is connected with protective device 7, and the signal output part of protective device 7 is connected with relay 9 signal input parts; Relay 9 one end signal outputs are connected with audible-visual annunciator 8 signal input parts, the other end and 10 interactive connections of I/O interface; The signal output part of float-type liquid level sensor 2 is connected with controller 5 by I/O interface 10 respectively with the signal input part of gasoline pump 3.
In fuel tank 1, adorn a float-type liquid level sensor 2, when the liquid level in the container reaches predeterminated position, the float of float-type liquid level sensor 2 can rise thereupon, when rising to when concordant with fuel tank 1 top, float-type liquid level sensor 2 will send signal to controller 5, controller 5 receives the power supply that cuts off self-service petrol pump 3 behind the signal immediately, drives acoustic-optic alarm 8 alert refueling processes simultaneously and finishes.
Claims (2)
