Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveyor chain technology, specifically a conveyor anti-wear scraper chain. Background Technology
[0002] A conveyor is a material handling machine that continuously transports materials along a certain route. It is also called a continuous conveyor. Conveyors can transport materials horizontally, inclined, and vertically, and can also form spatial transport lines. Objects can also be transported in a conveyor via chains.
[0003] Patent document CN222347943U discloses a chain for a conveyor, which includes "a chain body mounted on the conveyor body. The chain body includes an outer chain plate, a pin, an inner chain plate, rollers, and sleeves. The outer chain plate and pin, as well as the inner chain plate and sleeve, are interference fits, while the rollers and sleeves, and the sleeves and pins, are clearance fits. A lubrication assembly is installed on the right side of the top of the conveyor body, a collection assembly is installed on the right side of the bottom of the conveyor body, and a tension adjustment assembly is installed in the middle of the bottom of the conveyor body. By rotating the handle block, the threaded column can be rotated, thereby moving the positioning frame downward. The rollers exert a downward pulling force on the inner surface of the chain body, thereby keeping the chain body in an appropriate tension state and preventing problems such as jumping, falling off, or slipping caused by slackness, thus improving the stability and reliability of the chain body transmission."
[0004] However, the aforementioned open-source conveyor chain mainly addresses the problem of existing chains easily slipping and falling off, but this chain requires frequent lubrication during use, resulting in high maintenance costs.
[0005] In view of this, it is necessary to develop a wear-resistant scraper chain for conveyors, which can reduce the number of times the chain needs to be lubricated and make the chain easier to use. Utility Model Content
[0006] The purpose of this utility model is to provide a wear-resistant scraper chain for conveyors to solve the technical problem mentioned in the background art that the chain needs to be frequently injected with lubricating oil during use, resulting in high maintenance costs.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a conveyor anti-wear scraper chain, comprising: a bottom chain plate, a pin shaft installed on the top of the bottom chain plate, and the bottom end of the pin shaft penetrating the bottom of the bottom chain plate; a lubrication assembly installed on the pin shaft, the lubrication assembly comprising an oil storage cavity, an oil outlet hole, a sleeve, and a sealing gasket; the oil storage cavity is opened inside the pin shaft, the oil outlet hole is opened on the outside of the pin shaft, and the oil outlet hole penetrates the inner wall of the oil storage cavity; the sleeve is installed on the outside of the pin shaft, and sealing gaskets are installed on the top and bottom of the sleeve.
[0008] Preferably, a limiting base plate is installed at the bottom end of the pin, and the limiting base plate is located below the bottom chain plate.
[0009] Preferably, the top of the pin has a through hole.
[0010] Preferably, a locking pin is installed at the top of the pin through a through hole.
[0011] Preferably, a reinforcing rib is installed on the top of the bottom chain plate, a top chain plate is installed on the top of the reinforcing rib, and the top of the top chain plate is penetrated by the top end of the pin.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. In this utility model, the oil storage cavity in the lubrication component is opened inside the pin, providing space for the filling of grease. The operator can fill the oil storage cavity with grease through the oil outlet. The sleeve is rotatably installed on the outside of the pin through the sealing washer. When the chain is used again, the grease inside the oil storage cavity will be discharged through the oil outlet to the space between the sleeve and the pin, lubricating the space between the sleeve and the pin, thereby playing a self-lubricating role and reducing the number of times the operator needs to lubricate the chain.
[0014] 2. The large and small head disassembly pins in this utility model are easy to disassemble and assemble. The locking pin is a flower-shaped locking pin. The small protrusions on the locking pin lock the pin shaft internally, which can prevent it from loosening and causing fatigue cracks during use. The reinforcing ribs make the stability between the bottom chain plate and the top chain plate higher. Attached Figure Description

[0025] Includes: a bottom chain plate 1, a pin 3 mounted on the top of the bottom chain plate 1, and the bottom end of the pin 3 penetrating the bottom of the bottom chain plate 1. A lubrication assembly is mounted on the pin 3. The lubrication assembly includes an oil storage cavity 6, an oil outlet 7, a sleeve 10, and a sealing gasket 11. The oil storage cavity 6 is opened inside the pin 3, the oil outlet 7 is opened on the outside of the pin 3, and the oil outlet 7 penetrates the inner wall of the oil storage cavity 6. The sleeve 10 is installed on the outside of the pin 3, and the top and bottom of the sleeve 10 are equipped with sealing gaskets 11.
[0026] The pin 3 is installed between the bottom chain plate 1 and the top chain plate 9, serving as a connection. The pin 3 provides a position for the installation of the lubrication assembly. The oil storage cavity 6 in the lubrication assembly is opened inside the pin 3, providing space for grease filling. The operator can fill the oil storage cavity 6 with grease through the oil outlet 7. The sleeve 10 is rotatably installed on the outside of the pin 3 through the sealing gasket 11. When the chain is used again, the grease inside the oil storage cavity 6 will be discharged through the oil outlet 7 to the space between the sleeve 10 and the pin 3, lubricating the space between the sleeve 10 and the pin 3, so that the sleeve 10 can rotate more smoothly. The sealing gasket 11 can prevent grease from leaking from both ends and prevent dust from entering between them, so that the grease can be used for a longer period of time and is also protected from contamination.
[0027] Please see Figures 1-4 A type of wear-resistant scraper chain for conveyors;
[0028] A limiting base plate 4 is installed at the bottom end of the pin 3, and the limiting base plate 4 is located below the bottom chain plate 1. A through hole 5 is provided at the top of the pin 3, and a locking pin 8 is installed at the top of the pin 3 through the through hole 5. A reinforcing rib 2 is installed at the top of the bottom chain plate 1, and a top chain plate 9 is installed at the top of the reinforcing rib 2, and the top chain plate 9 is penetrated by the top end of the pin 3.
[0029] When installing the pin 3, it passes through the top of the limiting base plate 4 and the top of the top chain plate 9, and is then positioned by the locking pin 8 through the through hole 5. The pin 3 is easy to disassemble and assemble with a large and small head. The locking pin 8 is a flower-shaped locking pin 8. The small protrusion on the locking pin 8 clamps the pin 3 internally, which can prevent it from loosening and causing fatigue cracks during use. The reinforcing rib 2 makes the stability between the bottom chain plate 1 and the top chain plate 9 higher.
[0030] The working principle is as follows: First, when the chain is in use, the top chain plate 9 and the bottom chain plate 1 are installed through the pin 3. The top of the pin 3 is fixed by the locking pin 8. The sleeve 10 is rotatably installed on the outside of the pin 3. The oil storage cavity 6 inside the pin 3 is filled with grease, so that the chain has a self-lubricating effect when in use, reducing the number of times the operator needs to add lubricating oil. The installation of the reinforcing rib 2 improves the stability between the bottom chain plate 1 and the top chain plate 9.
