[0031] See also Figure 1-4 The utility model provides a double-row chain scraper chain, including a plurality of chain link units 1 and a plurality of extended pins 2. Through holes are provided at both ends of the chain link units 1. The extended pins 2 are rotatably connected in the through holes, and any two adjacent chain link units 1 are rotatably connected at the head and tail through the extended pins 2. The plurality of chain link units 1 are connected to form a parallel and spaced double-row chain scraper chain. The two ends of each extended pin 2 are fixed with a limit stopper 3. By setting the limit stopper 3, the firmness of the connection between the chain link units 1 can be improved.

[0032] Two adjacent extended pin shafts 2 are slidably connected to a supporting side plate 4 . Specifically, two through holes are provided on the surface of the supporting side plate 4 , and the extended pin shaft 2 passes through the through holes to achieve a sliding connection with the supporting side plate 4 .

[0033] A heightened scraper 5 is provided between the two rows of chains, and the two ends of the heightened scraper 5 are fixedly connected to the supporting side plates 4 on both sides respectively; at the same time, the heightened scraper 5 is fixedly connected to the front and rear two extended pins 2 of a chain link unit 1. Since the extended pin 2 has high strength, the front and rear fixation is more reliable. At the same time, three-point fixation is achieved through the two extended pins 2 and the supporting side plates 4, so that the heightened scraper 5 is not easy to tip over or break, which greatly improves the service life of the heightened scraper 5.

[0034] Furthermore, at least two rubber buffer pads 6 are provided on the outer sleeve of the extended pin shaft 2, and rubber buffer pads 6 are provided on both sides of the supporting side plate 4. By providing the rubber buffer pads 6, the hard contact between the supporting side plate 4 and the limit baffle 3 can be effectively reduced, and the hard contact between the supporting side plate 4 and the chain link unit 1 can also be effectively reduced, thereby effectively reducing the damage to the supporting side plate 4 due to friction.

[0035] A plurality of reinforcing ribs 7 are also fixed on the surface of the heightened scraper plate 5. The surface of the reinforcing ribs 7 is provided with a slot, and the upper end of the heightened scraper plate 5 can be inserted into the slot of the reinforcing ribs 7, so that the reinforcing ribs 7 are connected to the heightened scraper plate 5. Specifically, during installation, the reinforcing ribs 7 are first inserted into the upper end of the heightened scraper plate 5, and the slot is used to engage with the heightened scraper plate 5, so that the position of the reinforcing ribs 7 can be locked, and then the reinforcing ribs 7 are welded to the surface of the heightened scraper plate 5 by electric welding to complete the installation of the reinforcing ribs 7.

[0036] A transverse reinforcement rod 8 is fixedly welded between two adjacent supporting side plates 4. The transverse reinforcement rod 8 passes through multiple reinforcement ribs 7. By providing the transverse reinforcement rod 8 and multiple reinforcement ribs 7, the connection firmness of the elevated scraper 5 can be effectively improved, and the service life of the elevated scraper 5 can be further improved.

[0037] Example 2

[0038] See also Figure 2-4 The difference between Example 2 and Example 1 is that a long slide groove 9 is further provided on the surface of the reinforcement rib 7, a transverse movable plate 10 is slidably connected in the long slide groove 9, an extension scraper plate 11 is fixedly connected to the surface of the transverse movable plate 10, and the surface of the extension scraper plate 11 is in contact with the side wall of the heightened scraper plate 5 on which the transverse reinforcement rod 8 is arranged.

[0039] A support shaft 12 is rotatably connected between the two reinforcement ribs 7, a driving gear 13 is fixedly connected to the outside of the support shaft 12, a tooth plate 14 is fixedly connected to the surface of the extended scraper 11, the driving gear 13 and the tooth plate 14 are meshed with each other, and a fixing component 15 for fixing the support shaft 12 is provided on the side of the reinforcement rib 7.

[0040] The fixing assembly 15 includes a threaded sleeve 16, a positioning disk 17, a threaded plug body 18, a return spring 22 and a limiting cam 23.

[0041] When it is necessary to adjust the extension height of the extended scraper 11, the threaded plug 18 can be loosened first. When the snowflake block 20 is away from the snowflake slot 19 under the elastic force of the reset spring 22, the positioning plate 17 and the support shaft 12 can be freely rotated. By rotating the support shaft 12 and the driving gear 13, the driving gear 13 and the toothed plate 14 are engaged with each other, and the long slide groove 9 is used to limit the horizontal movable plate 10, the extension height of the extended scraper 11 can be adjusted. When the height is adjusted, the threaded plug 18 is tightened again, and the limiting cam 23 is pushed by the threaded plug 18. The limiting cam 23 will slide along the limiting slot 24 and approach the positioning plate 17 until the snowflake block 20 is engaged in the snowflake slot 19, thereby fixing the positioning plate 17, thereby fixing the support shaft 12 and the driving gear 13, and finally fixing the extended scraper 11.

[0042] By adjusting the height of the extended scraper 11, it is possible to adapt to the transportation of materials of different capacities within a certain range, which not only provides convenience for users, but also improves the application range of the entire scraper chain and improves its practicality. Moreover, this structure can be applied to a variety of chain forms, such as straight plate chains, bent plate chains, and die-forged chains.

[0043] A slotted groove 21 is formed at one end of the threaded plug body 18 away from the snowflake block 20 , and a slotted screwdriver is inserted into the slotted groove 21 , which facilitates the rotation of the threaded plug.
