Description

Technical Field

[0001] The invention relates to the technical field of hopper conveyors, in particular to a die forging chain conveyor. Background Art

[0002] The existing bucket chain conveyor conveying structure is mainly divided into two types. The first type is to convey by plate chains on both sides of the bucket. This type of bucket chain conveyor with plate chains has some significant technical problems, including low strength and poor load-bearing capacity. Due to the limited strength of the plate chain, the bucket chain conveyor is prone to damage or failure to operate normally when transporting heavy objects or using for a long time.

[0003] The second type is to install a single die forged chain at the bottom of the hopper for conveying. Although this type of chain bucket conveyor with die forged chain bottom conveying solves the strength problem to a certain extent, there is a problem that the traction effect is affected because the hopper is in direct contact with the die forged chain. In addition, the hot slag will have a greater negative impact on the carrier sprocket on the die forged chain, causing wear and damage to the carrier sprocket, thereby greatly reducing the service life of the die forged chain and carrier sprocket.

[0004] These shortcomings limit the application of existing chain bucket conveyors in high temperature and high load environments. An improved conveying structure is urgently needed to improve its performance and service life. To this end, we propose a die forged chain conveyor. Summary of the invention

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0027] See also Figures 1 to 3 In an embodiment of the present invention, a die forging chain conveyor includes at least a plurality of hoppers connected in series and two die forging chain groups, and the die forging chain groups are respectively arranged on the left and right sides of the hopper. The die forging chain group is composed of a plurality of die forging chain units 1 connected in series, and each die forging chain unit 1 includes a first die forging chain 2 and a second die forging chain 6. The first die forging chain 2 is divided into a first middle part 3 and two first end parts 4, and the two first end parts 4 are respectively provided with a first pin hole 5, the thickness of the first middle part 3 is greater than the thickness of the first end part 4, and the outer wall of the first middle part 3 is fixedly connected with a connecting plate 18 for connecting with the hopper; the second die forging chain 6 has the same size as the first die forging chain 2, and the second die forging chain 6 is divided into a second middle part 7 and two second end parts 8, and the two second end parts 8 are respectively provided with a second pin hole 9, and the thickness of the second middle part 7 is greater than the thickness of the second end part 8; wherein, the first die forging chain 2 and the second die forging chain 6 are spaced apart, and the first pin hole 5 and the second pin hole 9 are connected by a pin shaft 20 to form the die forging chain unit 1, and the outer wall of the pin shaft 20 located between the first pin hole 5 and the second pin hole 9 is sleeved with a shaft sleeve 21.

[0028] By adopting the above scheme, the die-forged chain conveyor realizes material transportation through a plurality of hoppers connected in series, and the two sides of the hopper are supported and driven by the die-forged chain group respectively, and the die-forged chain group connects each die-forged chain unit 1 through the pin 20 to ensure the continuity and stability of the overall transmission. The design of the thickness of the middle part of the first and second die-forged chains 6 provides higher bending resistance, and the connecting plate 18 is used to firmly connect the second die-forged chain 6 with the hopper to ensure the carrying capacity and operation efficiency of the conveyor.

[0029] Specific combination Figure 1 and Figure 2In one embodiment of the present invention, a convex ring 10 is provided on the first pin hole 5 and the second pin hole 9 to improve the strength of the first pin hole 5 and the second pin hole 9. The convex ring 10 is designed to enhance the strength of the pin hole, prevent stress concentration caused by long-term wear or high-load operation, and avoid deformation or breakage of the pin hole.

[0030] In addition, in some preferred embodiments of the present invention, the first reinforcing plate 12 is integrally formed with the first die forging chain 2, and the second reinforcing plate 14 is integrally formed with the second die forging chain 6. By adopting the integral molding technology, the first reinforcing plate 12 and the first die forging chain 2, the second reinforcing plate 14 and the second die forging chain 6 form a complete integral structure during the manufacturing process, reducing the stress concentration phenomenon caused by the connector or welding, and enhancing the overall strength and rigidity of the chain.

[0031] Furthermore, the thickness of the first middle portion 3 and the second middle portion 7 is 24 mm, and the thickness of the first end portion 4 and the second end portion 8 is 12 mm. The design of different thicknesses ensures that the die forging chain has sufficient strength and stability in the middle portion of the key stress-bearing area, while reducing the thickness of the end portion to reduce friction and improve transmission efficiency.

[0032] Specific combination Figure 3 In one embodiment of the present invention, a first square hole 11 is provided on the first middle portion 3 of the first die forging chain 2, a first reinforcing plate 12 is provided in the first square hole 11, and a first connecting hole is provided on the first reinforcing plate 12. The first square hole 11 and the first reinforcing plate 12 therein are designed to increase the structural strength of the die forging chain. By providing a reinforcing plate in the first middle portion 3, the connecting hole can withstand greater force, reduce fatigue damage caused by long-term use, and further improve the load-bearing capacity of the die forging chain.

[0033] On the basis of the previous embodiment, further, a second square hole 13 is provided on the second middle portion 7 of the second die forging chain 6, a second reinforcing plate 14 is provided in the second square hole 13, and a second connecting hole is provided on the second reinforcing plate 14. The design of the square hole in the second middle portion 7 and the second reinforcing plate 14 is similar to that of the first die forging chain 2, and is used to improve the structural strength and durability of the second die forging chain 6. The second reinforcing plate 14 bears pressure through the second connecting hole, and enhances the stability of the die forging chain, ensuring the firmness of the chain during the conveying process.

[0034] On the basis of the previous embodiment, further, a rotating shaft 15 is provided between the first connecting hole and the second connecting hole, and a supporting sprocket 16 is sleeved on the rotating shaft 15. By arranging the rotating shaft 15 between the first connecting hole and the second connecting hole, and sleeved on the rotating shaft 15, the die forged chain conveyor can convey materials more smoothly. The supporting sprocket 16 provides additional support and rotation functions, reduces the friction of the chain, and ensures the smoothness and stability of the conveying.

[0035] Secondly, two bearings 17 are provided on the carrier wheel 16 to improve the running smoothness of the carrier wheel 16. The two bearings 17 installed on the carrier wheel 16 provide additional support by reducing friction, so that the carrier wheel 16 can rotate more smoothly. The design of the bearings 17 ensures that the carrier wheel 16 can still run smoothly under high load conditions, thereby reducing energy loss and wear.

[0036] Secondly, the carrier sprocket wheel 16 is a split structure, and the split structure design of the carrier sprocket wheel 16 allows its various components to be manufactured and assembled independently. This design facilitates replacement and maintenance, reducing maintenance costs. When the carrier sprocket wheel 16 is partially worn or fails, only the damaged part needs to be replaced, and the entire carrier sprocket wheel 16 does not need to be replaced.

[0037] Specific combination Figure 2 and Figure 3 In one embodiment of the present invention, a plurality of threaded holes 19 are provided on the connecting plate 18 for threaded connection with the hopper. By providing a plurality of threaded holes 19 on the connecting plate 18, the die forging chain can be conveniently fixed to the hopper by bolts or screws. The threaded connection method not only ensures the firmness of the connection, but also facilitates disassembly and installation, adapts to hoppers of different specifications, and increases the flexibility of the entire system.

[0038] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
