Description

Technical Field

[0001] This utility model relates to the field of hydraulic system technology, specifically to an excavator refueling auxiliary device. Background Technology

[0002] Excavators are increasingly used in a wide range of applications, no longer limited to traditional earthmoving operations, but also extending to port loading and unloading, scrap steel processing in steel mills, railway bulk logistics transfer stations, and train leveling and unloading. The working environment has become more complex and variable. When the excavator's fuel runs out, operators usually refuel manually. Manual refueling relies on visual observation to transmit and confirm changes in fuel levels, making it difficult to accurately and stably control the amount of fuel added. This often results in overfilling or underfilling.

[0003] Therefore, the inventors aimed to solve the problem of designing a device that is simple in structure, low in cost, provides real-time prompts at the refueling end, and assists manual refueling in controlling the amount of fuel added to avoid over- or under-fueling. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an excavator refueling auxiliary device that features a simple structure, low cost, real-time refueling end prompts, and assists manual refueling by controlling the amount of fuel added to avoid over- or under-fueling.

Detailed Implementation

[0016] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0017] Example 1: See Figures 1 to 2This utility model discloses a structural view and bottom structural view of an excavator refueling auxiliary device, including a controller 1. The controller 1 is electrically connected to a monitor 4 and a battery 3 via an excavator power switch 2. Turning on the excavator power switch 2 activates the power supply to the vehicle control system. The controller 1 is also electrically connected to an auxiliary function switch 5, which is electrically connected to a fuel tank level sensor 7 via wires. The auxiliary function switch 5 is also electrically connected to a buzzer 8, a full tank indicator light 9, and a low tank indicator light 10 via wires. When refueling is needed, the driver turns on the auxiliary function switch 5 from inside the cab, activating the fuel tank level sensor 7, buzzer 8, full tank indicator light 9, and low tank indicator light 10. Since the excavator itself carries fuel... The fuel tank level detection function displays the approximate fuel level in the tank in real time on the fuel gauge. Therefore, when refueling is not needed, the auxiliary function switch 5 can be turned off to disable the refueling assistance function. When the auxiliary function switch 5 is turned on, the fuel tank level sensor 7 is activated. Since the fuel tank is empty or at a low fuel level at this time, the fuel tank level sensor 7 is not triggered, and the controller 1 receives a signal to control the low-full indicator light 10 to illuminate. When the driver adds fuel to the excavator's fuel tank 12, the fuel level gradually rises. When the fuel tank level sensor 7 is triggered, the controller 1 receives a signal and controls the low-full indicator light 10 to turn off, while the full indicator light 9 illuminates. At the same time, the buzzer 8 emits a warning sound. The driver can then determine that the excavator's fuel tank 12 is full based on the indicator lights and the warning sound, and immediately stop refueling.

[0018] The fuel tank level sensor 7 is located inside the excavator fuel tank 12. The excavator fuel tank 12 is equipped with a filler neck 13. The vertical distance between the fuel tank level sensor 7 and the lower end of the filler neck 13 is no more than 30mm. This distance is the margin set when adding fuel. Since the human body's reaction speed is not uniform, this margin is the margin for the human body to react to. The actual amount of fuel added may fluctuate depending on individual circumstances.

[0019] The buzzer 8 is electrically connected to the reset switch 6. A sealed mounting base 11 is provided on the outer shell of the excavator's fuel tank 12. The full tank indicator light 9, the low tank indicator light 10, the buzzer 8, and the reset switch 6 are all located on the sealed mounting base 11. The wiring sections of the full tank indicator light 9, the low tank indicator light 10, the buzzer 8, and the reset switch 6 are all located inside the sealed mounting base 11, and the outer shell is glued to the sealed mounting base 11. The indicator lights and the buzzer 8 are located near the fuel filler neck 13. After the driver finishes refueling, he can manually press the reset switch 6 to temporarily stop the buzzer 8 from beeping. All buzzers 8 on the market have this function. The operation can be completed by the driver entering the cab and turning off the auxiliary function switch 5 after the refueling operation is completed. If the driver does not enter the cab and turn off the auxiliary function switch 5 for a long time after pressing the reset switch 6, the controller 1 will continuously receive the signal from the fuel tank level sensor 7 and issue a command to the buzzer 8 to sound. After the standby time of the buzzer 8 expires, it will sound again to provide a secondary reminder to the driver to operate according to regulations.

[0020] The wiring harness between the full bin indicator light 9, the incomplete bin indicator light 10, the buzzer 8, and the controller 1 is introduced into the excavator's cab through a wire channel.

[0021] To distinguish them, the full box indicator light 9 has an "F" mark on its lampshade surface, which represents the English word "full" and indicates that it is full. The full box indicator light 9 also emits a green light.

[0022] To distinguish them, the surface of the lampshade of the Less-than-Full indicator light 10 is marked with an "E" symbol, which represents the English word "empty" and indicates an empty state. At the same time, the Less-than-Full indicator light 10 emits a red light.

[0023] To facilitate operation by the driver before refueling, the auxiliary function switch 5 is located on the side of the control panel inside the driver's cab.

[0024] Example 2: Unlike the above examples where auxiliary function switch 5 and reset switch 6 are used to control the function of the entire device, this utility model, in order to facilitate the control of the start and stop of the auxiliary function at both ends near the cab and the excavator fuel tank 12, can also use a double-control switch to form a double-control circuit for control. The auxiliary function switch 5 is replaced by two double-control switches to form a double-control circuit. One of the double-control switches is located in the cab, and the other is located near the excavator fuel tank 12. Through the working principle of the double-control circuit, the function of starting and stopping the auxiliary function at both ends can be realized. A double-control switch is a switch with two normally open and normally closed contacts, which is a pair. Usually, two double-control switches are used to control the electrical appliances on a circuit. That is to say, there can be two switches to control the switch of the electrical appliance, such as turning on the switch downstairs and turning off the switch upstairs.

[0025] This utility model installs a liquid level sensor at the filler neck 13 port inside the excavator's fuel tank 12 to detect the fuel level near the filler neck 13 in real time. At the same time, a device that is easy to detect visually and audibly is installed near the fuel tank as a reminder. This achieves a simple structure, low cost, real-time reminder at the refueling end, and assists in controlling the amount of fuel added during manual refueling to avoid over- or under-filling.
