[0002] In the material transportation process, the auger conveyor is a device used to transport materials such as cement, lime, coal, etc. It uses the auger as a transmission component to transport the materials to the destination through a spiral drive. The auger conveyor consists of a trough, a motor, an auger and other components. The entire device drives the auger to rotate through the motor, and the materials move up or down along the inner wall of the trough, and finally reach the destination of transportation.

[0003] The utility model relates to an auger conveyor with a U-shaped structure. When realizing material transportation, a large-span auger is usually used, that is, an auger with a longer conveying distance is used for material transportation. However, the technical problem encountered is that the auger with a longer conveying distance must be erected in the middle section by a supporting device, and the supporting device cannot affect the transportation of the material.

[0004] The supporting device described above usually adopts an inverted bearing seat. However, when in use, if the auger or the bearing seat fails, it must be disassembled as a whole. The auger and the bearing seat need to be separated on the U-shaped groove for maintenance, which has high maintenance costs and low maintenance efficiency. Furthermore, the bearing seat in the prior art adopts a bearing design inside. Because powdered materials are often encountered during material transportation, this working environment can easily cause bearing damage, affecting normal use.

DETAILED DESCRIPTION

[0024] The utility model is further described below through an implementation method. As shown in the accompanying drawings, the following description is only an exemplary explanation. Those skilled in the art can make further structural improvements based on the following explanation. The scope of protection of this patent shall be based on the scope recorded in the claims.

[0025] Embodiment 1:

[0026] A large span auger conveyor, such as Figure 1 , 2As shown, it includes a U-shaped groove 1, in which an auger 5 is arranged, and the inner end of the U-shaped groove 1 is provided with a motor fixing frame 2 and an auger fixing seat 12, and the motor fixing frame 2 is provided with a motor support plate 21, and a driving motor 3 is provided on the motor support plate 21. The gearbox on the driving motor 3 is connected to the auger 5 through a coupling 31, or when the driving motor 3 adopts a servo motor, it can be directly connected to the auger 5 through the coupling 31.

[0027] The U-shaped groove 1 is provided with a middle support frame 4, through which the middle part of the auger with a larger span is supported. A plurality of middle support frames 4 can be provided on the upper part of the U-shaped groove 1 to realize material transportation over a longer distance. In this embodiment, for exemplary purposes only, one middle support frame 4 is used to realize the connection between the auger 5 and the two sections of the auger extension section 51.

[0028] like Figure 4 , 5 As shown in , 6, the middle support frame 4 includes a top fixing frame 41, a vertical connecting section 42 and a rotating support portion 45, and a horizontal fixing plate 44 is arranged between the rotating support portion 45 and the top fixing frame 41; a fixing sleeve 49 and a rotating shaft 48 are arranged inside the rotating support portion 45, and plug-in avoidance portions 481 are arranged at both ends of the rotating shaft 48, and a driven end 47 is arranged to cooperate with the rotating shaft 48, and a docking portion 471 that cooperates with the plug-in avoidance portion 481 is arranged on the driven end 47. A fixing bolt is also arranged between the plug-in avoidance portion 481 and the docking portion 471, and the fixing bolt is used to lock and fix the two. When disassembling, the plug-in avoidance portion 481 and the docking portion 471 can be radially separated after removing the fixing bolt.

[0029] When the driven end 47 is connected to the auger 5, those skilled in the art may use a quick-release method to connect, or may weld the driven end 47 to the auger 5 as an integral part when shipped. In this embodiment 1, the auger 5 and the auger extension section 51 both use an integral spiral auger, the structure of which includes an auger shaft 53 at the axis, and an integral spiral blade is provided on the auger shaft 53.

[0030] Furthermore, when the middle support frame 4 is in use, it needs to withstand a large torque as a top support component. In order to ensure the stability of the middle support frame 4 in operation, two side reinforcement plates 43 are arranged between the top fixing frame 41 and the vertical connecting section 42, and the strength of the two components is supplemented by the side reinforcement plates 43.

[0031] Embodiment 2:

[0032] In Example 1, the auger 5 and the auger extension section 51 both adopt an integrated spiral auger. The disadvantage of this design is that if the auger 5 or the auger extension section 51 is used for a long time, there will be a disadvantage that the spiral blades are damaged. If a certain point on the spiral blade is damaged, the entire blade needs to be replaced during maintenance, resulting in cost waste during maintenance.

[0033] This embodiment is further improved on the basis of the embodiment 1, and the auger 5 and the auger extension section 51 are set with segmented spiral blades, that is, a plurality of independent auger blades 52 are welded in a spiral state on each auger shaft 53, and fixed by the spiral state distribution. This welding can also be changed to a bolt locking method, which is more convenient for personnel to assemble and disassemble during maintenance. If the independent auger blade 52 is damaged during use, it can be replaced separately to achieve local maintenance, so that the equipment can be continuously and stably operated at a lower maintenance cost.

[0034] Furthermore, the utility model uses manganese steel or polymer wear-resistant material as the raw material for the fixed sleeve 49. In actual operation, the stable operation between the two components can be ensured by lubricating the two components. In this embodiment, the inner diameter of the fixed sleeve 49 is provided with a side sealing groove 493 and a middle annular oil guide groove 491. The middle annular oil guide groove 491 is provided at intervals, and the radial groove 492 passes through the middle annular oil guide grooves 491. The side sealing groove 493 is provided in two front and back positions. When the fixed sleeve 49 rotates in coordination with the rotating shaft 48, after the lubricating oil is applied in the middle annular oil guide groove 491, the lubricating oil will pass through the middle annular oil guide grooves 491 through the radial groove 492 to form a lubrication system. A sealing ring is installed in the side sealing groove 493 to prevent the leakage of the lubricating oil and the invasion of impurities, which can effectively improve the rotational lubrication.

[0035] like Figure 4 , 5 As shown in Figures 6 and 7, a clamp 46 is provided on the periphery of the rotating support part 45 as an auxiliary fixing structure, and the clamp 46 connects and fixes the rotating support part 45 and the horizontal fixing plate 44. At the same time, a support frame end face 451 is also provided at the front and rear ports of the rotating support part 45. The support frame end faces 451 at the two ends cooperate with the clamp 46 in the middle, and the three together realize the protective support of the rotating support part 45 and the horizontal fixing plate 44.

[0036] In summary, the utility model can realize large-span auger conveying through the above structural arrangement. A vertically quick-detachable rotating shaft 48 and then a driven end 47 are hoisted in the U-shaped groove 1. This structure can be easily and quickly assembled, and does not require overall disassembly and assembly. It has low maintenance costs and high maintenance efficiency. After the shaft sleeve structure is adopted, the rotation failure rate is greatly reduced. It is an ideal large-span auger conveyor.
