Description

Technical Field

[0001] The utility model relates to a grease filling device, belonging to the technical field of mechanical lubrication. Background Art

[0002] Logistics vehicles refer to various vehicles used for transporting goods, such as trucks, lorries, etc. These vehicles need to be regularly maintained during transportation to ensure their normal operation, and grease is an essential lubricant for these transportation vehicles. Specifically, grease can reduce the friction between vehicle components, reduce wear, and extend the service life of components. Generally, logistics vehicles need to be filled with grease at least once a month to maintain the good running state of the vehicles.

[0003] Currently, the existing grease filling method usually uses a fuel tank and a grease gun in cooperation. The fuel tank is used to store grease, and the grease gun is used to output grease, so as to add grease to the parts that need lubrication or maintenance in the vehicle.

[0004] A grease filling device for vehicle maintenance disclosed in the Chinese utility model patent with the publication number CN209084380U includes an oil storage cylinder for storing grease. The top of the oil storage cylinder is connected with an upper cover. The left side of the upper cover is connected with a first turning handle. The top of the first turning handle is installed and fixed with a plunger pump, and an air pump is installed on the top of the plunger pump. The left side of the plunger pump is fixedly connected with an air inlet pipe, and the right side of the plunger pump is threadedly connected with a high-pressure rubber hose, and the right end of the high-pressure rubber hose is fixedly connected with an oil injection gun.

[0005] The above reference example stores grease through the oil storage cylinder and outputs oil through the oil injection gun during work. However, the grease stored in the oil storage cylinder is prone to solidify to a state where it cannot be output at low temperatures, so that the vehicle cannot be maintained and lubricated. Therefore, improvement is urgently needed. Summary of the Invention

[0006] In order to overcome the above disadvantages in the prior art, the utility model designs a grease filling device, which can heat the grease to prevent the grease from solidifying and unable to be output, and can be stirred during heating, improving the work efficiency.

[0007] In order to achieve the above object, the utility model adopts the following technical scheme: A grease filling device includes a main fuel tank and an oil injection gun that are connected to each other and used for oil output. A stirring and heating device is arranged in the main fuel tank. The stirring and heating device includes a driving device, a rotating mechanism and a heating component. The rotating mechanism is installed inside the main fuel tank and is driven to rotate by the driving device. The heating component includes a plurality of heating units evenly installed around the rotating mechanism. The heating unit includes a rotating plate and a plurality of electric heating stirring rods installed at the bottom end of the rotating plate.

[0008] Further, the rotation mechanism includes a rotating disk and a gear disk fixedly installed inside the main fuel tank. The rotating disk is arranged directly below the gear disk. The driving device is arranged at the upper end of the gear disk, and the output shaft at the bottom end of the driving device rotatably penetrates through the gear disk and is in transmission connection with the rotating disk. A number of transverse rotating rods are evenly connected along the circumference on the side surface of the rotating disk. A gear assembly meshing with the gear disk is installed on the transverse rotating rod, and the gear assembly is fixedly connected to the top end of the rotating plate.

[0009] Further, the gear assembly includes a first meshing gear arranged at the upper end of the transverse rotating rod, a second meshing gear arranged at the lower end of the transverse rotating rod, and a third meshing gear. A connecting shaft rotatably penetrating through the transverse rotating rod is fixedly connected between the first meshing gear and the second meshing gear. The third meshing gear is rotatably installed at the bottom of the free end of the transverse rotating rod and meshes with the second meshing gear. An extension rod is fixedly installed at the bottom of the third meshing gear, and the free end of the extension rod is fixedly connected to the top end of the rotating plate.

[0010] Further, a secondary fuel tank is arranged at the bottom end of the main fuel tank. The secondary fuel tank is communicated with the main fuel tank through a communication port. A filter screen is arranged at the communication port. An oil outlet is communicated at the bottom end of the secondary fuel tank, and the output end of the oil outlet is communicated with an oil gun through an oil pipe.

[0011] Further, an installation sleeve plate is fixedly sleeved on the secondary fuel tank, and a number of support legs are fixedly installed at the bottom end of the installation sleeve plate.

[0012] Further, a fixed collar is integrally fixed at the top end of the inner ring of the gear disk. A number of installation rods are evenly fixed along the circumference on the side surface of the fixed collar, and the free ends of the installation rods are all fixedly connected to the inner wall of the main fuel tank.

[0013] Further, an opening and closing valve is arranged at the communication port, and the opening and closing valve is arranged at the top of the filter screen.

[0014] Further, the bottom ends of both the main fuel tank 1 and the secondary fuel tank 2 are arranged in a funnel shape.

[0015] Compared with the prior art, the present utility model has the following characteristics and beneficial effects:

[0016] The utility model drives the rotating disk to rotate by starting the driving device. During the rotation of the rotating disk, the transverse rotating rod will be driven to rotate. When the transverse rotating rod rotates, the meshing gear one can revolve around the gear disk. And because the meshing gear one meshes with the gear disk, the meshing gear one will rotate on its own axis while revolving. Thus, the meshing gear two can be driven to rotate by the rotation of the meshing gear one on its own axis, and then drive the meshing gear three and the extension rod to rotate in sequence. Therefore, while the electric heating stirring rod rotates synchronously with the meshing gear three, it can also rotate around the gear disk, which can effectively increase the contact area between the electric heating stirring rod and the grease inside the main fuel tank. Through the heating of the electric heating stirring rod and the stirring effect of the electric heating stirring rod, the solidified grease can be melted very efficiently, so that the grease can flow into the auxiliary fuel tank through the filter screen and be pumped out through the oil gun.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following describes the present utility model in more detail in conjunction with the embodiments.

[0025] Embodiment 1

[0026] Please refer to Figures 1 to 5, the butter filling device of this embodiment includes a main fuel tank 1 and an oil gun that are connected to each other and used for oil output. In order to meet the oil output pressure, an oil pump is arranged between the oil gun and the main fuel tank 1 to assist in oil output, ensuring the smooth progress of the operation.

[0027] A stirring and heating device 5 is arranged in the main fuel tank 1. The stirring and heating device 5 includes a driving device 51, a rotating mechanism, and a heating component. The rotating mechanism is installed inside the main fuel tank 1 and is driven to rotate by the driving device 51. The heating component includes three heating units evenly installed around the rotating mechanism. The heating unit includes a rotating plate 7 and four electric heating stirring rods 71 installed at the bottom end of the rotating plate 7.

[0028] Specifically, the rotating mechanism includes a rotating disk 531 and a gear disk 52 fixedly installed inside the main fuel tank 1. The rotating disk 531 is arranged directly below the gear disk 52. The driving device 51 is arranged at the upper end of the gear disk 52, and the output shaft at the bottom end of the driving device 51 rotates through the gear disk 52 and is in transmission connection with the rotating disk 531. Three transverse rotating rods 53 are evenly connected along the circumferential direction on the side surface of the rotating disk 531. A gear assembly meshing with the gear disk 52 is installed on the transverse rotating rod 53, and the gear assembly is fixedly connected to the top end of the rotating plate 7.

[0029] Furthermore, the gear assembly includes a first meshing gear 54 arranged at the upper end of the transverse rotating rod 53, a second meshing gear 55 arranged at the lower end of the transverse rotating rod 53, and a third meshing gear 56. A connecting shaft that rotates through the transverse rotating rod 53 is fixedly connected between the first meshing gear 54 and the second meshing gear 55. The third meshing gear 56 is rotatably installed at the bottom of the free end of the transverse rotating rod 53 and meshes with the second meshing gear 55. An extension rod 57 is fixedly installed at the bottom of the third meshing gear 56, and the free end of the extension rod 57 is fixedly connected to the top end of the rotating plate 7.

[0030] Furthermore, a secondary fuel tank 2 is arranged at the bottom end of the main fuel tank 1. The secondary fuel tank 2 is communicated with the main fuel tank 1 through a communication port. A filter screen 6 is arranged at the communication port. The bottom end of the secondary fuel tank 2 is communicated with an oil outlet 21. The output end of the oil outlet 21 is communicated with the oil gun through an oil pipe. The setting of the filter screen 6 can prevent impurities from entering the secondary fuel tank 2 and ensure the cleanliness of the output oil.

[0031] Furthermore, an installation sleeve plate 3 is fixedly sleeved on the secondary fuel tank 2, and four support legs 4 are fixedly installed at the bottom end of the installation sleeve plate 3.

[0032] Furthermore, a fixed collar 521 is integrally fixed at the top end of the inner circle of the gear disk 52. Four mounting rods 8 are evenly fixed along the circumferential direction on the side surface of the fixed collar 521. The free ends of the mounting rods 8 are all fixedly connected to the inner wall of the main fuel tank 1.

[0033] Further, an opening and closing valve (not shown in the figure) is provided at the connecting port. The opening and closing valve is arranged at the top end of the filter net 6. The arrangement of the opening and closing valve can prevent the grease in the middle of the main fuel tank 1 from blocking the connecting port due to its relatively slow melting speed. The opening and closing valve can be opened to output the grease after the grease is stirred and heated for a period of time, ensuring smooth oil discharge.

[0034] Embodiment 2

[0035] The rest is the same as Embodiment 1, except that, please refer to Figure 6 , the bottom ends of both the main fuel tank 1 and the auxiliary fuel tank 2 are funnel-shaped, which is convenient for the liquid grease to flow out.

[0036] The working principle of the present utility model: Grease is input through the oil inlet provided on the main fuel tank 1. When the oil gun cannot discharge oil due to cold weather, the driving device is started to drive the rotating disk 531 to rotate. During the rotation of the rotating disk 531, the transverse rotating rod 53 will be driven to rotate. When the transverse rotating rod 53 rotates, the first meshing gear 54 can revolve around the gear disk 52. And because the first meshing gear 54 meshes with the gear disk 52, the first meshing gear 54 will rotate on its own while revolving. Thus, the rotation of the first meshing gear 54 can drive the second meshing gear 55 to rotate, and then drive the third meshing gear 56 and the extension rod 57 to rotate in sequence. As a result, while the electric heating stirring rod 71 rotates synchronously with the third meshing gear 56, it can also rotate around the gear disk 52. Furthermore, the contact area between the electric heating stirring rod 71 and the grease inside the main fuel tank 1 can be effectively increased. Through the heating of the electric heating stirring rod 71 and the stirring action of the electric heating stirring rod 71, the solidified grease can be melted very efficiently, so that the grease can flow into the auxiliary fuel tank 2 through the filter net 6 and be pumped out through the oil gun.
