[0001] This utility model belongs to the field of chain manufacturing technology, specifically relating to a scraper conveyor chain. Background Technology

[0002] In conventional scraper conveyor chains, the pins are directly locked to the chain plates by locking pins. During the conveying process, the pins are usually in direct contact with the material.

[0003] When conveying highly abrasive materials, the pins and locking pins will wear down too quickly, causing the chain connection structure to fail and become unusable. Utility Model Content

[0018] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0019] This embodiment provides a scraper conveyor chain, including a pin 1, a sleeve 2, a roller 3, an inner chain plate 4, an outer chain plate 5, a nut 6, a pad 8, and a protective cover 9.

[0020] A sleeve 2 and two outer chain plates 5 are fitted on the outer side of the pin 1, and a roller 3 and two inner chain plates 4 are fitted on the outer side of the sleeve 2. For example, see Figure 1 The sleeve 2 is fitted onto the outer side of the middle section of the pin 1. The outer link plate 5 has a mounting hole that matches the pin 1. The outer link plate 5 is fitted onto the outer side of the pin 1 through the mounting hole, and the sleeve 2 is clamped between the two outer link plates 5.

[0021] For example, see Figure 1 The roller 3 is sleeved on the outer side of the middle section of the sleeve 2. The inner chain plate 4 has a rotating hole that matches the sleeve 2. The inner chain plate 4 is rotatably sleeved on the outer side of the sleeve 2 through the rotating hole, and the roller 3 is clamped between the two inner chain plates 4.

[0022] The first end of the pin 1 has a pressure cap 10, the second end of the pin 1 has an external thread, the nut 6 is screwed to the second end of the pin 1, and the pad 8 is clamped between the nut 6 and the outer chain plate 5. The side wall of the pad 8 has an external thread. For example, see Figure 1-2 A pressure cap 10 is coaxially fixed to the first end of the pin 1, and the diameter of the pressure cap 10 is larger than the inner diameter of the mounting hole of the outer link plate 5. The second end of the pin 1 is provided with an external thread. The nut 6 is screwed to the second end of the pin 1. The nut 6 cooperates with the pressure cap 10 to lock and fix the outer link plate 5 and the sleeve 2.

[0023] For example, see Figure 2 A pad 8 is held between the nut 6 and the outer chain plate 5. The pad 8 can play a protective role and prevent the outer chain plate 5 from being worn, squeezed and deformed.

[0024] For example, see Figure 2-3Nut 6 is a slotted nut. The second end of pin 1 has a through hole. After nut 6 is screwed onto the second end of pin 1, the through hole of pin 1 aligns with the slot of nut 6. Cotter pin 7 passes through the through hole of pin 1, and the slot of nut 6 allows cotter pin 7 to pass through. This forms a locking structure that prevents relative rotation between nut 6 and pin 1, thus preventing nut 6 from falling off too quickly.

[0025] The protective cover 9 has a ring structure and internal threads. The protective cover 9 is threadedly connected to the pad 8.

[0026] For example, see Figure 1 , Figure 3 After the protective cover 9 is screwed to the pad 8, the protective cover 9 can surround the nut 6, pin 1, and cotter pin 7 on the inside, thus playing a protective role. Moreover, the protective cover 9 can be installed or removed by rotating it, which is very convenient.

[0027] Based on the above structure, the scraper conveyor chain provided in this embodiment, by setting a protective cover 9, can protect the pin 1, nut 6, cotter pin 7, and other structures, preventing direct contact between the material and these structures during conveying, thus avoiding excessive wear and effectively extending the chain's service life. During assembly, the protective cover 9 can be installed last to avoid affecting the installation of the nut 6 and other structures. If the protective cover 9 is damaged, it can be replaced at any time; disassembly and assembly are very convenient, ensuring that the internal structure of the protective cover 9 is not affected.

[0028] Based on the above technical solutions, in the technical solution provided in this embodiment, the pad 8 includes an inner ring plate 801 and an outer ring plate 802. The outer ring plate 802 is coaxially sleeved on the outside of the inner ring plate 801. The outer ring plate 802 and the inner ring plate 801 are fixedly connected by a connecting plate 803. The inner ring plate 801 is clamped between the nut 6 and the outer chain plate 5. The side wall of the outer ring plate 802 is provided with external threads. The protective cover 9 is threadedly connected to the outer ring plate 802.

[0029] For example, see Figure 4-5 The inner ring plate 801 is adapted to the pin 1. The inner ring plate 801 is sleeved on the outside of the pin 1. By tightening the nut 6, the inner ring plate 801 is clamped between the nut 6 and the outer chain plate 5. The inner ring plate 801 can protect the outer chain plate 5 and prevent the outer chain plate 5 from being worn, squeezed and deformed.

[0030] For example, multiple connecting plates 803 are provided between the outer ring plate 802 and the inner ring plate 801. The connecting plates 803 are arranged radially and are evenly spaced circumferentially. The two ends of each connecting plate 803 are fixedly connected to the outer ring plate 802 and the inner ring plate 801, respectively. When the inner ring plate 801 is deformed by compression, the gap between the outer ring plate 802 and the inner ring plate 801 provides sufficient deformation space for the inner ring plate 801. This minimizes the impact on the outer ring plate 802, ensuring the smooth installation of the subsequent protective cover 9.

[0031] For example, the thickness of the connecting plate 803 is less than the thickness of the inner ring plate 801. The connecting plate 803 is attached to the outer link plate 5, which can reduce the impact on the connecting plate 803.

[0032] In the technical solution provided in this embodiment, the outer link plate 5 has an L-shaped structure. The outer link plate 5 is provided with reinforcing ribs 11.

[0033] For example, see Figure 6 The outer chain plate 5 includes a horizontal plate and a vertical plate. The horizontal plate is used to connect with structures such as the pin 1, while the vertical plate is used to push materials. The reinforcing ribs 11 are welded and fixed to the horizontal and vertical plates at both ends, which can improve the stability of the outer chain plate 5 and extend the service life of the chain.

[0034] For example, see Figure 7 The thickness of the reinforcing rib 11 is less than the thickness of the outer chain plate 5. The reinforcing rib 11 is flush with the top of the outer chain plate 5. This reduces the impact of materials on the reinforcing rib 11 during the conveying process.
