[0033] Specifically, the main part of the bucket elevator 2 is used to load materials and lift them from a low place to a high place. The chain 3 is used as a transmission component of the bucket elevator 2 to drive the feeding bucket 4 to move in the vertical direction. The feeding bucket 4 is used to load the materials to be lifted and is a carrier for lifting the materials. The sprocket 1 5 and the sprocket 2 6 cooperate with the chain 3 to guide the movement path of the chain 3 to ensure that the chain 3 correctly bypasses and lifts the materials. The active bevel gear 8 is driven by the motor 1 7 and meshes with the driven bevel gear 10 to transmit power. The driven bevel gear 10 meshes with the active bevel gear 8 to receive power and transmit it to the cam 11. The cam 11 is driven by the driven bevel gear 10 and pushes the connecting plate through its special contour shape. 18 and push rod 17, thereby driving piston 15 to move in sleeve 14, piston 15 slides in sleeve 14, and controls the in and out of lubricating oil through its movement, spring 16 provides elastic force to help piston 15 reset and assist in pushing lubricating oil, connecting plate 18 connects push rod 17 and cam 11, converts the movement of cam 11 into linear motion, oil extraction pipe 19 connects sleeve 14 and oil storage tank 20, and is used to extract lubricating oil from oil storage tank 20 into the inside of sleeve 14, oil storage tank 20 stores lubricating oil and provides continuous lubrication for chain 3, oil outlet pipe 21 transports lubricating oil in sleeve 14 to nozzle 22, nozzle 22 sprays lubricating oil onto chain 3 and sprocket to reduce friction.
[0034] Reference Figure 1 and Figure 2 The scraping assembly includes a motor 23, the outside of the motor 23 is fixedly connected to the rear side of the inside of the feed hopper 4, the output end of the motor 23 is fixedly connected to a threaded rod 24, the outside of the threaded rod 24 is threadedly connected to a threaded sleeve 26, the front side of the inside of the feed hopper 4 is fixedly connected to a slide bar 25, the outside of the slide bar 25 is slidably connected to a slider 27, and a scraper 28 is fixedly connected between the slider 27 and the threaded sleeve 26.
[0035] Specifically, the motor 23 is fixed to the rear side of the feed hopper 4 as the power source of the scraping assembly, and the entire scraping action is driven by the rotation of the output end. The threaded rod 24 is fixedly connected to the output end of the motor 23, and the rotation of the motor generates a rotational motion. The outer part of the threaded rod is provided with a thread, which cooperates with the threaded sleeve 26 to convert the rotational motion into a linear motion. The threaded sleeve 26 is threadedly connected to the outer part of the threaded rod 24. When the threaded rod rotates, the threaded sleeve will move linearly along the threaded rod. The slide bar 25 is fixed to the front side of the feed hopper 4 to provide a guide for the slider 27 to ensure that the slider moves smoothly on the linear track. The slider 27 is slidably connected to the outer part of the slide bar 25 and is fixedly connected to the threaded sleeve 26. The motion trajectory of the slider is determined by the slide bar, and it moves on the slide bar following the linear motion of the threaded sleeve. The scraper 28 is fixedly connected between the slider 27 and the threaded sleeve 26, and is a component that directly performs the scraping action. When the slider moves on the slide bar, the scraper moves back and forth inside the feed hopper to remove the residual material.
[0036] Reference Figure 2 - Figure 5 An oil inlet valve 31 is arranged outside the oil extraction pipe 19, an oil outlet valve 29 is arranged outside the oil outlet pipe 21, a solenoid valve 30 is arranged outside the oil outlet pipe 21 and at the top of the oil outlet valve 29, one end of the spring 16 is fixedly connected to the inner wall of the sleeve 14, and the other end of the spring 16 is fixedly connected to the middle of the piston 15, the outer periphery of the cam 11 and the connecting plate 18 are abutted, two nozzles 22 are respectively arranged on the top of the sprocket 26 and the sprocket 15, the side end of the threaded rod 24 is rotatably connected to the inside of the feeding hopper 4, the threaded sleeve 26 and the outside of the slider 27 are both slidably connected to the inside of the feeding hopper 4, and the bottom of the scraper 28 is slidably connected to the inner wall of the feeding hopper 4.
[0037] Specifically, the oil inlet valve 31 is located outside the oil extraction pipe 19, and controls the process of the lubricating oil flowing from the oil storage tank 20 to the sleeve 14. It can be a manually or automatically controlled valve, used to open or close the flow of the lubricating oil. The oil outlet valve 29 is located outside the oil outlet pipe 21, and controls the process of the lubricating oil flowing from the sleeve 14 to the nozzle 22. It opens after the piston 15 compresses the lubricating oil, allowing the lubricating oil to flow out. The solenoid valve 30 is located outside the oil outlet pipe 21 and above the oil outlet valve 29, and is usually used to control the opening and closing of the oil outlet valve. The solenoid valve can be remotely controlled by an electrical signal to realize the timing or on-demand supply of the lubricating oil. One end of the spring 16 is fixed to the inner wall of the sleeve 14, and the other end is fixed to the middle of the piston 15. Its function is to provide reverse elastic force when the piston moves, help the piston to reset, and provide a certain pressure when the piston compresses the lubricating oil. The two nozzles 22 are respectively arranged on the top of the sprocket 2 6 and the sprocket 1 5, and are used to evenly spray the lubricating oil onto the chain and the sprocket to reduce friction and wear. The side end of the threaded rod 24 is rotatably connected to the inside of the feeding hopper 4, and is driven to rotate by the motor 23. The thread cooperates with the threaded sleeve 26 to achieve linear motion. The threaded sleeve 26 and the slider 27 are both slidably connected to the inside of the feeding hopper 4. The threaded sleeve cooperates with the threaded rod, and the slider slides on the slide rod 25 to jointly achieve the linear motion of the scraper 28. The bottom of the scraper 28 is slidably connected to the inner wall of the feeding hopper 4. Through its reciprocating motion inside the feeding hopper, the residual material is removed to prevent the material from sticking.
[0038] Working principle: The bucket elevator 2 is started through the control box, which in turn drives the chain 3 to work, and the chain 3 drives the feeding hopper 4 to lift and transport the materials. During the long-term high-speed operation of the chain 3, due to the effect of friction, the chain links, pins and other parts of the chain will be worn. At this time, the starting motor 7 drives the active bevel gear 8 to rotate. Due to the meshing connection between the active bevel gear 8 and the driven bevel gear 10, the driven bevel gear 11 is driven to rotate, and the cam 11 is driven to rotate at the same time. The rotation of the cam 11 will push the connecting plate 18 and the push rod 17 to drive the piston 15 to move. During the process, the piston 15 will compress the spring 16 inside the sleeve 14, and at the same time, a negative pressure will be formed inside the sleeve 14. At this time, the lubricating oil inside the oil storage tank 20 will be extracted and enter the sleeve 14 through the oil extraction pipe 19 and the oil inlet valve 31. Since the solenoid valve 30 is in a closed state at this time, the compressed spring 16 inside the sleeve 14 cannot push the piston 15 to reset it, thereby ensuring that the position of the connecting plate 18 is always close to the sleeve 14 and ensuring that the driven bevel gear 10 and the cam 11 are not disturbed during rotation. When the solenoid valve 30 is opened, the spring 16 is reset to push the piston 15 inside the sleeve 14 toward the driven bevel gear 10, and then the piston 15 compresses the lubricating oil inside the sleeve 14, and discharges the lubricating oil from the oil outlet valve 29 into the oil outlet pipe 21, and then the lubricating oil is sprayed out from the nozzle 22 and falls on the sprocket 1 5 and the sprocket 2 6. As the bucket elevator 2 runs, the sprocket 1 5 and the sprocket 2 6 rotate continuously, and the lubricating oil is applied to the chain 3 for lubrication to reduce the wear caused by its activity. When there is residual material in the feeding hopper 4, the motor 2 23 drives the threaded rod 24 to rotate, and then the scraper 28 is driven to move back and forth inside the feeding hopper 4 through the threaded sleeve 26 and the slider 27 to scrape off the residual material inside the feeding hopper 4, thereby reducing the labor intensity of the workers and avoiding the waste of materials.
[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
