Description

Technical Field

[0001] This invention relates to the field of chain technology, specifically to a palm oil chain with an outer chain plate featuring bosses. Background Technology

[0002] A chain is a flexible mechanical part composed of a series of interconnected metal (or other material) links or links. It achieves functions such as power transmission, material conveying, or heavy lifting by meshing with sprockets or directly bearing loads. Among them, the palm oil chain is a special industrial conveyor chain designed specifically for the entire production process of palm oil. It is used in all stages of palm fruit harvesting, conveying, pressing, and processing, and is the core conveying component of palm oil factories and plantations.

[0003] In the prior art, a chain typically consists of an outer chain plate, an inner chain plate, a pin, a bushing, and rollers. During operation, a baffle is usually installed on the outer side of the chain. When the baffle becomes loose or falls off, the end of the chain pin will come into contact with the baffle, thereby accelerating the wear of the pin, affecting the chain's operating efficiency, and reducing the chain's service life.

[0004] Therefore, we propose a palm oil chain with an outer chain plate featuring bosses. Summary of the Invention

[0005] The purpose of this invention is to provide a palm oil chain with an outer chain plate having bosses, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a palm oil chain with an outer link plate and a boss, comprising a chain, the chain comprising an outer link and an inner link, the outer link comprising an outer link plate and a pin passing between the outer link plates, the inner link comprising an inner link plate, a sleeve passing between the inner link plates, and a roller fixed outside the sleeve and located between the inner link plates, the outer link and the inner link being fixedly connected by the pin passing through the sleeve, the outer link plate being located outside the inner link plate, and further comprising: The anti-wear mechanism is located on one side of the chain and on the surface of the outer chain plate to prevent wear on the pins. A lubrication assembly is located inside the pin and is used for lubrication of the chain connection.

[0007] Preferably, the wear-resistant mechanism includes: The base is fixed to the outer surface of the outer chain plate. A connecting groove is provided on the surface of the base. A connecting seat is inserted into the connecting groove. A boss is fixed on the top surface of the connecting seat. Limiting components are located on both sides of the base and are used to fix the boss.

[0008] Preferably, the limiting component includes: The base has four limiting holes, which are respectively opened on both sides of the connecting seat. The base has four rectangular movable cavities inside, which correspond one-to-one with the limiting holes. A movable rod passes through the inside of each movable cavity, and the end of the movable rod is inserted into the inner wall of the limiting hole. A connecting block is fixedly sleeved on the outer surface of the movable rod. A spring is sleeved on the outer surface of the movable rod. One end of the spring is fixed to the surface of the connecting block, and the other end of the spring is fixed to the inner wall of the movable cavity.

[0009] Preferably, a pull rod is fixed between the outer ends of the two movable rods on one side.

[0010] Preferably, the lubrication assembly includes: An oil cavity is formed inside a pin. Multiple oil outlet holes are evenly formed on the surface of the pin and communicate with the oil cavity. A cylindrical plug is provided on the inner wall of the oil cavity, and a fastening thread is formed on the outer surface of the cylindrical plug. The cylindrical plug is threaded to the inner wall of the oil cavity through the fastening thread.

[0011] Preferably, a connecting rod is fixed to one end of the cylindrical block, and an oil brush is fixed to the end of the connecting rod.

[0012] Preferably, a rotating block is fixed to the other end of the cylindrical block, and two rubber sealing rings are fixedly sleeved on the outer surface of the cylindrical block.

[0013] Preferably, an elastic locking plate is provided on the outer side of one of the outer chain plates, and the beginning and end of the chain are hinged together by a pin, and the elastic locking plate is engaged in the groove of the pin for axial anti-disengagement and limiting.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through the cooperation of the outer chain plate and the anti-wear mechanism, enables the boss to protect the outer chain plate located on the outside. The boss is higher than the pin. After the baffle loosens or falls off, the boss contacts the baffle, thereby protecting the end of the pin and extending the service life of the pin, thus improving the service life of the chain. Furthermore, through cooperation with the limiting component, the replacement of the boss is facilitated, further extending the use of the chain.

[0015] 2. The present invention facilitates the injection of lubricating oil through the setting of the lubrication component, so that the lubricating oil overflows from the oil outlet hole, thereby lubricating the pin, sleeve and roller, reducing wear between chain components and extending the service life of the chain. During the removal of the column-shaped block, the oil brush slides in the oil cavity and rotates during the removal process, which facilitates the oil brush to clean the sludge in the oil cavity.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-5 This invention provides a technical solution: a palm oil chain with an outer link plate and a boss, comprising a chain, the chain comprising an outer link and an inner link, the outer link comprising an outer link plate 1 and a pin 2 passing between the outer link plates 1, the inner link comprising an inner link plate 3, a sleeve 4 passing between the inner link plates 3, and a roller fixed outside the sleeve 4 and located between the inner link plates 3, the outer link and the inner link being fixedly connected by the pin 2 passing through the sleeve 4, the outer link plate 1 being located outside the inner link plate 3, one of the outer link plates 1 having an elastic locking piece 5 provided on its outer side, the beginning and end of the chain being hinged together by the pin, and the elastic locking piece 5 being engaged in the groove of the pin 2 for axial anti-disengagement and limiting.

[0020] In this embodiment, as Figure 1 , Figure 3 and Figure 5 It also includes an anti-wear mechanism, which is set on one side of the chain and located on the surface of the outer chain plate 1 and is used to prevent wear of the pin 2. The anti-wear mechanism includes: a base 9, which is fixed to the outer surface of the outer chain plate 1. A connecting groove 10 is opened on the surface of the base 9. A connecting seat 11 is inserted into the inside of the connecting groove 10. A boss 6 is fixed on the top surface of the connecting seat 11. It should be noted that the boss 6 is higher than the end of the pin 2. When the baffle is close to the pin, it can contact the pin 2 through the boss 6, thereby avoiding contact between the pin 2 and the baffle, thus preventing wear of the pin 2, extending the service life of the pin 2, and thus increasing the service life of the chain. Limiting components are disposed on both sides of the base 9 and used to fix the boss 6. The limiting components include: The limiting hole 12 is provided in four parts and is respectively opened on both sides of the connecting seat 11. The base 9 has four rectangular movable cavities 13 inside, which correspond one-to-one with the limiting hole 12. A movable rod 14 is movably passed through the inside of the movable cavity 13, and the end of the movable rod 14 is inserted into the inner wall of the limiting hole 12. A connecting block 15 is fixedly sleeved on the outer surface of the movable rod 14. A spring 16 is sleeved on the outer surface of the movable rod 14. One end of the spring 16 is fixed to the surface of the connecting block 15, and the other end of the spring 16 is fixed to the inner wall of the movable cavity 13.

[0021] After prolonged wear, the thickness of the boss 6 will be greatly reduced. At this time, by pulling the movable rod 14, the end of the movable rod 14 will be disengaged from the limiting hole 12, so that the staff can easily remove the connecting seat 11 of the boss 6 from the connecting groove 10 and then replace the boss 6. Insert the new boss 6 into the base 9, and under the elastic force of the spring 16, insert the end of the movable rod 14 into the limiting hole 12, thereby fixing the boss 6.

[0022] It should be noted that a pull rod 17 is fixed between the outer ends of the two movable rods 14 on one side. The pull rod 17 makes it easy for the staff to pull the two movable rods 14 on one side at the same time.

[0023] Furthermore, such as Figure 1 and Figure 4 The lubrication assembly is located inside the pin 2 and is used for lubrication of the chain connection. The lubrication assembly includes an oil cavity 18, which is located inside the pin 2. The surface of the pin 2 is evenly provided with multiple oil outlet holes 8, which are connected to the oil cavity 18. The inner wall of the oil cavity 18 is provided with a columnar plug 19, and the outer surface of the columnar plug 19 is provided with a fastening thread 20. The columnar plug 19 is threadedly connected to the inner wall of the oil cavity 18 through the fastening thread 20.

[0024] By rotating the cylindrical plug 19, the cylindrical plug 19 is removed from the oil chamber 18. Then, the operator injects an appropriate amount of lubricating oil into the oil chamber 18. After injection, the cylindrical plug 19 is tightened. During the transmission process, the lubricating oil overflows from the oil outlet 8, thereby lubricating the pin 2, sleeve 4 and roller, reducing wear between chain components and extending the service life of the chain.

[0025] It is worth noting that, such as Figure 4 A connecting rod 22 is fixed to one end of the cylindrical plug 19, and an oil brush 23 is fixed to the end of the connecting rod 22. A rotating block 7 is fixed to the other end of the cylindrical plug 19. The rotating block 7 facilitates the rotation of the cylindrical plug 19. During the removal of the cylindrical plug 19, the oil brush 23 slides in the oil cavity 18. At this time, it rotates during the removal process, which facilitates the oil brush 23 to clean the oil sludge in the oil cavity 18. Two rubber sealing rings 21 are fixedly sleeved on the outer surface of the cylindrical plug 19. After the cylindrical plug 19 is tightened and fixed, the rubber sealing rings 21 seal the cylindrical plug 19 to prevent the lubricating oil from flowing out.
