Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveying device technology, specifically to a belt conveyor with a large inclination angle. Background Technology
[0002] Inclined-angle belt conveyors are widely used in mining, metallurgy, and chemical industries for transporting bulk materials. Due to the large conveying angle, the belt's running angle at the driven roller is usually close to a right angle, causing the belt to bear greater shear and frictional forces at this position. This accelerates belt wear and shortens its service life. The cost of a single replacement can be as high as 50,000 to 100,000 yuan.
[0003] In addition, for the sake of workshop space layout, after the conveyor belt finishes conveying upwards, the lower return belt is raised and supported by lifting rollers, thus freeing up space below for the arrangement of production equipment. However, for conveying at large angles, two rubber baffles are generally installed on the conveyor belt surface to prevent powdery materials from slipping off the sides. To further facilitate the conveying of powdery materials and prevent slippage during large-angle conveying, conveyor baffles are also installed on the conveyor belt surface. A conveying space is formed between adjacent conveyor baffles, thereby pushing the powdery materials upwards. Therefore, after the belt returns downwards, the conveyor surface comes into contact with the lifting rollers. Although both the rubber baffles and the conveyor baffles can deform elastically, the contact points between them and the lifting rollers will still experience significant vibration due to unevenness, affecting the equipment's lifespan. In particular, the rubber baffles and conveyor baffles are prone to long-term pressure deformation and damage. Utility Model Content
[0004] This invention addresses the shortcomings of existing technologies by providing a belt conveyor with a large inclination angle.
[0005] This utility model is achieved through the following technical solution: a belt conveyor with a large inclination angle is provided, including an upper roller, a raised roller, and a lower roller arranged in an inclined manner from top to bottom, and two side-by-side support frames. The two ends of the upper roller, the two ends of the raised roller, and the two ends of the lower roller are respectively shafted to the two support frames. The conveyor belt also includes a conveyor belt that passes over the upper roller and the lower roller. The upper roller and the lower roller are in contact with the back of the conveyor belt. The upper end of the raised roller is in contact with the conveying surface of the conveyor belt. Two rubber side baffles are fixedly attached to the conveying surface of the conveyor belt, and multiple conveying baffles are also fixedly attached to the conveying surface of the conveyor belt. The two ends of each conveying baffle are respectively connected to two rubber side baffles. The raised roller includes a central support tube and two side support tubes at both ends. The conveying surface of the conveyor belt is in contact with the two side support tubes, and the rubber side baffles and conveying baffles are in contact with the central support tube.
[0006] As an optimization, the rubber side baffle is wavy and perpendicular to the conveyor belt.
[0007] As an optimization, the lifting roller also includes a roller shaft and two disks fixed to the roller shaft. The two ends of the central support tube are fixed to the two disks respectively, and the two side support tubes are fixed to the outer ring of the disks.
[0008] As an optimization, it also includes a first support roller and a second support roller. The upper roller, the first support roller, the second support roller and the lower roller are arranged obliquely from top to bottom. The first support roller and the second support roller are both in contact with the back of the conveyor belt.
[0009] As an optimization, the support frame includes a first column, a second column, and a third column arranged in sequence. The third column is inclined and its upper end is fixedly connected to the upper end of the second column. A first crossbeam is fixedly connected between the first column and the second column, and a second crossbeam is fixedly connected between the second column and the third column. The upper end of the rotating roller shaft is connected to the first crossbeam, the lower end of the rotating roller shaft is connected to the third column, and the lifting rotating roller shaft is connected to the second column.
[0010] As an optimization, the first support roller shaft is connected to the second crossbeam, and the second support roller shaft is connected to the third column.
[0011] The beneficial effects of this utility model are as follows: This utility model provides a belt conveyor with a large inclination angle. By adjusting the position of the driven roller, the running angle of the belt at the driven roller is changed from a near right angle to a gentle slope, thereby reducing belt wear at that position and extending the belt's service life. Furthermore, the return belt of the lower layer is raised by the lifting roller, which facilitates the utilization of the space below. The lifting roller is set in a stepped shape, thereby reducing vibration and damage to the belt during operation. Attached Figure Description

[0018] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.
[0019] like Figures 1-4 As shown, this utility model discloses a belt conveyor with a large inclination angle, including two side-by-side support frames, and an upper roller 1, a first support roller 2, a second support roller 3, and a lower roller 4 arranged in an inclined manner from top to bottom. The inclined arrangement means that they are arranged sequentially in one direction with gradually decreasing heights. It also includes a lifting roller 6. The upper roller 1, the lifting roller 6, and the lower roller 4 are also arranged in an inclined manner from top to bottom. Figure 1 As shown, the lifting roller 6 is located below the first support roller 2.
[0020] The upper roller 1, the first support roller 2, the lifting roller 6, the second support roller 3 and the lower roller 4 are coaxially arranged, and the two ends of all rollers are respectively connected to two support frames through bearing seats.
[0021] The conveyor belt 5 passes over the upper roller 1, the first support roller 2, the second support roller 3, and the lower roller 4. The upper roller 1, the first support roller 2, the second support roller 3, and the lower roller 4 are all in contact with the back side of the conveyor belt 5. The back side refers to the side that does not contact the material, while the conveying surface refers to the side that contacts the material. The raised roller 6 is in contact with the conveying surface of the conveyor belt 5.
[0022] The support frame includes a first column 7, a second column 8, and a third column 9 arranged sequentially. All three columns are fixed to the ground. The first column 7 and the second column 8 are perpendicular to the ground. The third column 9 is inclined and its upper end is fixedly connected to the upper end of the second column 8, forming a triangular structure. A first crossbeam 10 is fixedly connected between the first column 7 and the second column 8, and a second crossbeam 11 is fixedly connected between the second column 8 and the third column 9. The second crossbeam 11 is lower than the first crossbeam 10.
[0023] The upper roller 1 is connected to the first crossbeam 10, the first support roller 2 is connected to the second crossbeam 11, the second support roller 3 is connected to the third column 9, the lower roller 4 is connected to the lower end of the third column 9, and the lifting roller 6 is connected to the second column 8 and located below the second crossbeam 11.
[0024] like Figure 2 As shown, two rubber side baffles 51 are fixed to the conveying surface of the conveyor belt 5. The rubber side baffles 51 are wavy and perpendicular to the conveyor belt 5, so that the deformation at the roller position is achieved through the wavy expansion and contraction. The two rubber side baffles 51 are arranged in parallel to prevent materials from spilling from both sides.
[0025] Multiple conveyor baffles 52 are fixedly attached to the conveying surface of the conveyor belt 5. The conveyor baffles 52 are rubber plates and perpendicular to the conveyor belt 5. Two rubber side baffles 51 are connected to each end of the conveyor baffles 52, thereby creating a space between adjacent conveyor baffles 52 to prevent material from slipping. The end faces of the conveyor baffles 52 and the end faces of the rubber side baffles 51 are at the same height.
[0026] Since the conveyor belt 5 has a conveyor baffle 52 and a rubber side baffle 51 on its conveyor surface, in order to achieve the fit between the conveyor surface and the raised roller 6.
[0027] The lifting roller 6 includes a roller shaft 61, two discs 62 fixed on the roller shaft 61, a central support tube 63, and two side support tubes 64 at both ends. The roller shaft 61, the central support tube 63, and the two side support tubes 64 are coaxially arranged, and the diameter of the central support tube 63 is smaller than the diameter of the two side support tubes 64.
[0028] The two ends of the central support tube 63 are fixedly connected to the two discs 62 respectively, and the two side support tubes 64 are fixedly connected to the outer ring of the discs 62. The conveying surface of the conveyor belt 5 is in contact with the two side support tubes 64, and the rubber side baffle 51 and the conveying baffle 52 are both in contact with the central support tube 63.
[0029] How to use this utility model:
[0030] like Figure 1 As shown, the motor drives the upper roller 1 to rotate, and the material is added to the conveyor belt 5 from above the lower roller 4 and is located in the space between the rubber side baffle 51 and the adjacent conveyor baffle 52. The material is conveyed upward by the movement of the conveyor belt 5 and finally output through the position of the upper roller 1.
[0031] like Figure 4 As shown, the conveying surface of the conveyor belt is in contact with the two side support pipes 64, and the rubber side baffles 51 and the conveying baffles 52 are both in contact with the central support pipe 63. Thus, the two side support pipes 64 support the two edges of the conveyor belt, and the central support pipe 63 supports the end faces of the rubber side baffles 51 and the conveying baffles 52, achieving smooth contact at the support positions, reducing noise and vibration, and reducing the deformation of the rubber side baffles 51 and the conveying baffles 52.
