DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-4 This application is described in further detail.

[0029] The present application embodiment discloses a coal conveyor discharger. Figure 1-4 A coal conveyor unloader comprises a unloading body 1, a driving motor 2 is arranged on one side of the unloading body 1, the output end of the unloading body 1 and the driving motor 2 is driven by a sprocket and a chain, a protective shell 3 fixedly connected to the unloading body 1 is arranged on the outside of the chain, a material storage box 4 is fixedly connected to the top of the protective shell 3, a connecting plate 6 is connected to the inside of the protective shell 3 through a first lifting part 5, a sealing tube 7 is fixedly connected to the bottom of the connecting plate 6, a sealing piston 8 is slidably connected to the inside of the sealing tube 7, an input pipe 9 with one end passing through the connecting plate 6 and the protective shell 3 is connected to one side of the sealing tube 7, one end of the input pipe 9 is connected to the material storage box 4, an output pipe 10 is connected to the bottom of the sealing pipe 7, and a one-way valve 11 is fixedly connected to both the input pipe 9 and the output pipe 10, and further comprises

[0030] The second lifting part 12 is used to drive the sealing piston 8 to move up and down.

[0031] The second lifting part 12 includes a limiting hole 121 opened on both sides of the connecting plate 6, and a resistance rod 122 passes through and is slidably connected inside the limiting hole 121. The top ends of the two resistance rods 122 are fixedly connected by a fixing plate 123, and the bottom of the fixing plate 123 is fixedly connected to a connecting rod 124 with one end passing through the connecting plate 6 and the sealing tube 7. The bottom end of the connecting rod 124 is fixedly connected to the sealing piston 8, and the connecting plate 6 and the fixing plate 123 are elastically connected by a spring 125.

[0032] The first lifting part 5 includes a threaded rod 51 rotatably connected to the outer side of the protective shell 3, and a limit plate 52 is threadedly connected to the threaded rod 51. Both sides of the bottom of the limit plate 52 are fixedly connected to limit rods 53 with one end passing through the protective shell 3. The bottom ends of the two limit rods 53 are fixedly connected to both sides of the top of the connecting plate 6, and a knob 54 is fixedly connected to the top of the threaded rod 51.

[0033] In the above embodiment, when adding lubricating oil to the chain, first, the threaded rod 51 is rotated by turning the knob 54, and the limit plate 52 begins to descend under the restriction of the two limit rods 53, thereby driving the two limit rods 53 to descend, thereby driving the connecting plate 6 to descend, so that the output pipe 10 is close to the chain, thereby facilitating the application of lubricating oil on the chain. At this time, the chain is driven to rotate by starting the drive motor 2. At this time, the roller inside the chain conflicts with the resistance rod 122, driving the resistance rod 122 to move upward, thereby driving the connecting plate 6 to rise, and the spring 125 is The chain 124 is stretched and the connecting rod 124 is driven up, thereby driving the sealing piston 8 up. The lubricating oil inside the storage box 4 is transmitted to the inside of the sealing tube 7 through the input pipe 9 through the one-way valve 11. When the contact rod 122 is separated from the roller inside the chain, the sealing piston 8 is driven down under the action of the spring 125. At this time, the lubricating oil is discharged from the inside of the sealing tube 7, and the chain is coated with the lubricating oil. Through the rotation of the chain, the sealing piston 8 is driven to rise and fall continuously, thereby driving the lubricating oil to be discharged evenly, so that the chain is coated more evenly and the work efficiency of the user is improved.

[0037] A roller 16 is rotatably connected between the two vertical plates 13 , and a brush 17 is fixedly connected to the outer side of the roller 16 .

[0038] On the basis of the above embodiment, when the first lifting part 5 drives the connecting plate 6 to descend, it further drives the brush 17 to descend, so that the brush 17 fits the chain. When the chain rotates, it can drive the second lifting part 12 to work, so that the sealing piston 8 is lifted and lowered, and the lubricating oil is discharged from the output pipe 10, and then enters the interior of the discharge box 14, and is discharged from the oil outlet nozzle 15, and the lubricating oil is evenly sprayed on the brush 17. The brush 17 rotates with the rotation of the chain, and the lubricating oil can be evenly applied to the sprocket, thereby improving the brushing effect on the chain.

[0039] The implementation principle of a coal conveyor unloader of an embodiment of the present application is as follows: when adding lubricating oil to the chain, first, the connecting plate 6 is driven to descend through the first lifting part 5, and then the sealing tube 7 and the input pipe 9 are driven to descend, so as to facilitate the application of lubricating oil on the chain, and then the driving motor 2 is started and driven, and the chain rotates, which can drive the second lifting part 12 to work, and then drive the sealing piston 8 to rise and fall. During the rising process of the sealing piston 8, the lubricating oil inside the storage box 4 is input into the inside of the sealing tube 7 through the input pipe 9 through the one-way valve 11. When the sealing piston 8 descends, the lubricating oil is discharged from the inside of the sealing tube 7, and the chain is coated with lubricating oil, so that the lubricating oil is discharged evenly, the chain is coated more evenly, and the work efficiency of the user is improved.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
