Description

Technical Field

[0001] This application relates to the field of belt conveyor technology, and more specifically to a belt conveyor head unloading rotating device. Background Technology

[0002] Traditional unloading devices suffer from poor material distribution flexibility due to their fixed, single unloading direction. Reliance on manual adjustment or additional equipment (such as unloading trolleys) easily leads to material spillage, high energy consumption, and space redundancy. Furthermore, material impact under high-drop conditions can cause hopper blockage, while existing improvements (such as articulated discharge hoppers and baffle adjustment) still suffer from limited adjustment range, complex structure, and reliance on external power. Therefore, a new type of unloading device is urgently needed, capable of achieving dynamic adjustment of the unloading direction over a wide range through simplified structural design, while optimizing material buffering and sealing performance to address the pain points of poor flexibility and insufficient environmental adaptability in existing technologies.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the background technology of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0004] In view of at least one of the above technical problems, this disclosure provides a belt conveyor head discharge rotation device, which mainly solves the problems of complex auxiliary equipment and easy blockage caused by material impact due to the fixed discharge direction of the traditional belt conveyor head.

[0005] According to one aspect of this disclosure, a belt conveyor head discharge rotating device is provided, comprising a fixed frame, a discharge hopper fixedly disposed relative to the fixed frame and used to receive materials conveyed by the belt conveyor, a discharge cylinder rotatably connected to the outlet of the discharge hopper via a slewing bearing assembly, a drive wheel disposed on the fixed frame via a bearing seat and correspondingly driven connected to the slewing bearing assembly, and a drive motor fixedly disposed at a corresponding position on the fixed frame and drivenly connected to the drive wheel via a coupling.

[0006] In some embodiments of this disclosure, the material discharge funnel includes an upper funnel and a lower arc-shaped funnel. The upper trapezoidal funnel includes a narrowed-diameter structure with a rectangular cross-section, and the lower arc-shaped funnel includes a narrowed-diameter arc-shaped structure with a rectangular inlet and a circular outlet.

[0007] In some embodiments of this disclosure, the slewing bearing assembly includes a slewing bearing with external teeth, an upper flange fixed to the top of the inner ring of the slewing bearing, and a lower flange fixed to the bottom of the outer ring of the slewing bearing. The upper flange is fixedly connected to the outlet of the lower arc-shaped funnel via a connecting steel pipe, and the lower flange is fixedly connected to the inlet of the discharge cylinder.

[0008] In some embodiments of this disclosure, the external teeth are disposed on the outer edge surface of the outer ring of the slewing bearing and mesh with the drive wheel, and the drive motor is connected to the fixed frame by mounting plate bolts.

[0009] In some embodiments of this disclosure, the discharge cylinder is an inclined cylinder that changes its discharge direction according to the rotation of the slewing bearing, and the axis of the inclined cylinder is set at a certain angle with the axis of the discharge funnel.

[0010] One or more technical solutions provided in the embodiments of this application have at least one of the following technical effects or advantages:

[0011] 1. The slewing bearing meets the rotation requirements of the discharge cylinder. Compared with traditional bearings, it can simultaneously withstand the combined loads of axial force, radial force and overturning moment, which greatly improves the impact resistance, wear resistance and service life of the discharge rotation device of the belt conveyor head in harsh environments. The slewing bearing assembly integrates gear meshing to realize the integration of power transmission and support. The structure is compact, while the flange connection and external gear design simplify installation and adapt to complex working conditions.

[0012] 2. The drive wheel axle is rigidly supported by a bearing housing, ensuring precise alignment with the meshing teeth of the slewing bearing, reducing transmission vibration and off-center wear, and improving rotational stability. A coupling connects the drive motor and the drive wheel, achieving efficient torque transmission while compensating for installation errors and axial displacement, avoiding noise and frequent maintenance issues. This combination simplifies the transmission structure, enhances system rigidity, and reduces energy loss, making it suitable for high-load, continuous-operation industrial scenarios.

[0013] 3. The double-layer design of the material discharge hopper expands the material receiving range and increases the buffer capacity, accommodating materials from multiple directions and reducing leakage. The lower arc-shaped hopper uses its curved surface to guide and buffer the impact of materials, reducing direct wear on the inner wall of the hopper and the bottom discharge cylinder. Furthermore, the modular design allows the material discharge hopper to be fixed to the frame with hopper support bolts, facilitating disassembly and maintenance. In addition, the double-layer segmented structure distributes stress, comprehensively improving the durability and operational stability of the belt conveyor head material discharge rotation device under high flow and high drop conditions.

[0021] This application provides a belt conveyor head discharge rotation device, which mainly solves the problems of complex auxiliary equipment and easy blockage caused by the fixed discharge direction of traditional belt conveyors.

[0022] The technical solution in this application embodiment addresses the aforementioned problems, with the following overall approach: The slewing bearing assembly 3 satisfies the rotational requirements of the conveyor head's material discharge rotating device, while significantly improving its impact resistance, wear resistance, and service life under harsh environments. The bearing seat 5 rigidly supports the axle of the drive wheel 6, reducing transmission vibration and eccentric wear. The coupling 7 connects the drive motor 8 and the drive wheel 6, achieving efficient torque transmission. By integrating the double-layered material discharge hopper 2, slewing bearing assembly 3, material discharge cylinder 4, drive motor 8, and drive wheel 6 onto the fixed frame 1, an integrated design solves the problems of misalignment risk and vibration superposition caused by independent installation of multiple components.

[0023] To better understand the technical solution of this application, the above technical solution will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] This example discloses a rotating device for unloading material at the head of a belt conveyor, including a fixed frame 1, such as... Figure 1 As shown, the fixed frame 1 is a rectangular frame that integrates other components. Its integrated rigid design solves the problems of misalignment and vibration superposition caused by independent installation of multiple components. In this embodiment, the fixed frame 1 has several mounting holes, allowing it to be fixed to the material outlet with bolts. A material receiving hopper 2 for receiving materials conveyed by the belt conveyor is fixed to the fixed frame 1. Figure 2 As shown, the material discharge hopper 2 includes an upper trapezoidal hopper 9 and a lower arc-shaped hopper 10. The double-layer design, compared to traditional single-layer hoppers, distributes stress, avoiding deformation and cracking caused by concentrated impact stress. This comprehensively improves the durability and operational stability of the belt conveyor head material discharge rotation device under high flow and high drop conditions, making it suitable for diverse applications. The upper trapezoidal hopper 9 includes a rectangular cross-section with a narrowed diameter, expanding the material receiving range, accommodating multi-directional material intake, and reducing leakage. The lower arc-shaped hopper 10 includes a rectangular inlet and a circular outlet with a narrowed diameter. The inlet shape of the lower arc-shaped hopper 10 corresponds to the outlet shape of the upper trapezoidal hopper 9, and the outlet shape corresponds to the inlet shape of the discharge cylinder 4. The narrowed diameter structure utilizes curved surface guidance to buffer material impact, reducing direct wear on the inner wall of the hopper and the bottom discharge cylinder 4. Meanwhile, the upper trapezoidal funnel 9 corresponds to the material outlet and is fixed to the fixed frame 1 by several funnel supports 11 bolts, adopting a modular design for easy disassembly and maintenance. In addition, the outlet of the lower arc-shaped funnel 10 is rotatably connected to a discharge cylinder 4 through a slewing bearing assembly 3. The discharge cylinder 4 is an inclined cylinder that changes the corresponding discharge direction as the slewing bearing assembly 3 rotates. The axis of the inclined cylinder is set at a certain angle with the axis of the discharge funnel 2 to facilitate control of the material flow direction.

[0025] like Figure 1 As shown, the fixed frame 1 is also equipped with a drive wheel 6 fixed by a bearing seat 5 and correspondingly connected to the slewing bearing assembly 3, and a drive motor 8 connected to the drive wheel 6 via a coupling 7. The bearing seat 5 is fixed to the fixed frame 1 and rigidly supports the axle of the drive wheel 6, ensuring precise alignment with the slewing bearing assembly 3, reducing transmission vibration and off-center wear, and improving rotational stability. The drive motor 8 is fixed to the fixed frame 1 by bolts on the mounting plate 19, and adopts a modular design for easy disassembly and maintenance. Preferably, the drive motor 8 is a servo motor, and the output end of the servo motor is connected to the axle of the drive wheel 6 via the coupling 7 to achieve efficient torque transmission and compensate for installation errors and axial displacement.

[0026] like Figure 3 , 4As shown, the slewing bearing assembly 3 includes a slewing bearing 12 with external teeth 13. The external teeth 13 are located on the outer edge of the outer ring of the slewing bearing 12 and mesh with the drive wheel 6. An upper flange 16 is fixed to the top of the inner ring 14 of the slewing bearing 12, and a lower flange 17 is fixed to the bottom of the outer ring 15 of the slewing bearing 12. The upper flange 16 is fixedly connected to the outlet of the lower arc-shaped funnel 10 via a connecting steel pipe 18, realizing the dynamic separation between the static lower arc-shaped funnel 10 and the slewing bearing 12. The lower flange 17 is fixedly connected to the inlet of the discharge cylinder 4, transmitting the rotational power of the outer ring 15 of the slewing bearing 12 to the discharge cylinder 4 to adjust the discharge direction. The connecting steel pipe 18 serves as a rigid transition structure between the upper and lower flanges, ensuring continuous flow of material from the lower arc-shaped funnel 10 to the discharge cylinder 4, and dispersing the dynamic stress during the rotation of the outer ring 15 of the slewing bearing 12, thus preventing structural deformation. The slewing bearing 12, with its inner ring 14 fixed and outer ring 15 rotating independently, along with the reinforcement of the upper and lower flange seals and connecting steel pipes 18, improves overall sealing performance and impact resistance. Compared to the gear and bearing transmission in existing technologies, it is easier to maintain and has a longer service life. Specifically, under the action of the drive motor 8, the outer ring 15 of the slewing bearing 12 is rotated through the drive wheel 6, thereby realizing the rotation of the discharge cylinder 4. Compared to existing technologies, this belt conveyor head discharge rotation device has high transmission efficiency, low maintenance cost, and strong operational reliability.

[0027] The conveyor head unloading device ensures the stability of the overall structure through the fixed frame 1. Combined with the unloading funnel 2 with a reduced diameter structure, the upper and lower split design effectively guides material flow and reduces blockage. The slewing bearing assembly 3 achieves stable rotation of the unloading cylinder 4 through the slewing bearing 12 with external teeth and the upper and lower flange connection structure. The external teeth 13 of the slewing bearing 12 mesh with the drive wheel 6 to drive the motor 8 through the coupling 7 to form a reliable power system. The inclined unloading cylinder 4 adopts an axial angle design to provide multi-directional unloading function.
