[0002] Belt conveyors are commonly used in bulk material conveying. However, when granular bulk materials fall onto the belt conveyor, the belt will be subjected to biased impact and deviate from the conveying track. Granular bulk materials are also prone to splashing and falling between the belt and the rollers driving the belt, causing the belt to slip and deviate from the conveying track, resulting in powder spillage. This can cause pollution of the working environment or, in severe cases, cause the belt conveyor to stop operating and endanger the personal safety of workers. Utility Model Content

[0003] The purpose of this utility model is to provide a bulk material conveying device that can prevent the conveyor belt from deviating from the conveying track due to the impact of the material, and also prevent bulk material from splashing and falling between the conveyor belt and the roller driving the conveyor belt.

[0010] Preferably, the pressing member has a first mounting plate and a second mounting plate connected to each other, the first mounting plate being fixedly connected to the frame, and the second mounting plate being used to press against the conveyor belt.

[0011] Preferably, the sealing assembly further includes a wear-resistant plate, which is fixedly connected to the side wall of the first mounting plate facing the receiving space, with the surface of the wear-resistant plate facing the receiving space.

[0012] Preferably, the sealing assembly further includes a pressure regulating component, which has a first through hole and a first threaded hole on the second mounting plate. The pressure regulating component is fixedly connected to the side wall of the second mounting plate away from the conveyor belt by bolts passing through the first through hole and engaging with the first threaded hole.

[0013] Preferably, the bulk material conveying device further includes a first idler roller, the shaft of which is rotatably connected to the frame, and the first idler roller is used to support the conveyor belt.

[0014] Preferably, the first idler roller includes a main support roller and an auxiliary support roller. The rotating shaft of the main support roller and the rotating shaft of the auxiliary support roller are respectively rotatably connected to the frame. The two auxiliary support rollers are symmetrically arranged on both sides of the main support roller. The central axis of the main support roller intersects with the central axis of the auxiliary support roller.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0036] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0039] When granular bulk material falls onto a belt conveyor, the conveyor belt experiences an eccentric impact and deviates from its conveying path. The granular material can also easily splash and fall between the conveyor belt and the drive belt rollers, causing the conveyor belt to slip and deviate from its conveying path. This results in powder spillage and material spillage, which can range from polluting the working environment to causing the belt conveyor to stop operating and endangering the personal safety of workers. Therefore, pressing down the conveyor belt and preventing bulk material from splashing and falling between the conveyor belt and the drive belt rollers is key to solving these technical problems. The following section will discuss... Figures 1 to 5 This document provides a detailed description of the bulk material conveying device provided in this embodiment.

[0040] Figure 1 A schematic diagram of the bulk material conveying device provided in this embodiment is shown. Figure 2 It shows Figure 1 A cross-sectional view of the material receiving end. Figure 3 It shows Figure 2 A magnified view of part A in the diagram. (See diagram below.) Figures 1 to 3 As shown, the bulk material conveying device provided in this embodiment is used to convey bulk material 100, including a frame 1, a conveyor belt 2, a roller 3, and a sealing assembly 4. The conveyor belt 2 has a receiving end for receiving bulk material 100 and a discharging end for discharging bulk material 100. The bulk material 100 falls from the receiving end of the conveyor belt 2 onto the conveyor belt 2 and is conveyed by the conveyor belt 2 to the discharging end, so that the conveyor belt 2 completes the conveying of the bulk material 100. The roller 3 is fixed on the frame 1 and is disposed at the receiving end of the conveyor belt 2. The rotating shaft of the roller 3 is connected to the output end of the drive component. The roller 3 is configured to drive the conveyor belt 2 to convey the bulk material 100. The sealing assembly 4 includes a pressing member 41, which is fixedly connected to the frame 1 and disposed at the receiving end. The pressing member 41 presses against the two ends of the conveyor belt 2 in the width direction. The pressing member 41 and the conveyor belt 2 enclose a receiving space for accommodating the bulk material 100. Specifically, the sealing assembly 4 includes two pressing members 41, which press against the two ends of the conveyor belt 2 along its width direction, respectively. The pressing members 41 and the conveyor belt 2 form a receiving space for accommodating the bulk material 100. It should be noted that the driving component can be a motor. Any driving component that can be coaxially connected to the rotating shaft of the roller 3 and can be used to drive the conveyor belt 2 to transport the bulk material 100 is within the protection scope of this embodiment and will not be described in detail here.

[0041] The bulk material conveying device provided in this embodiment connects the rotating shaft of the roller 3 to the output end of the drive component, so that the roller 3 can drive the conveyor belt 2 to convey bulk material 100. By using the pressing member 41 to press against the two ends of the conveyor belt 2 along the width direction, when the bulk material 100 falls from the receiving end onto the conveyor belt 2, the friction generated by the pressing member 41 pressing against the conveyor belt 2 prevents the conveyor belt 2 from deviating along its width direction. At the same time, the pressing member 41 and the conveyor belt 2 form a receiving space for accommodating the bulk material 100. The bulk material 100 contained in the receiving space will not splash and fall between the conveyor belt 2 and the roller 3 that drives the conveyor belt 2, thereby preventing the conveyor belt 2 from slipping and deviating, preventing powder spillage, pollution of the working environment, and endangering the personal safety of workers.

[0042] Continue as Figures 1 to 3As shown, the pressing member 41 has a first mounting plate 411 and a second mounting plate 412 connected to each other. The first mounting plate 411 is fixedly connected to the frame 1, and the second mounting plate 412 is used to press against the conveyor belt 2, thereby achieving a reliable connection between the pressing member 41 and the frame 1, and enabling the second mounting plate 412 to stably press against the conveyor belt 2, thereby preventing the conveyor belt 2 from being subjected to biased material receiving impact and deviating from the conveying trajectory.

[0043] Preferably, the sealing assembly 4 further includes a wear-resistant plate 42, which is fixedly connected to the side wall of the first mounting plate 411 facing the receiving space. The surface of the wear-resistant plate 42 faces the receiving space, thereby preventing the loose material 100 from sliding and rubbing against the pressing member 41 and causing wear to the pressing member 41 when it falls onto the conveyor belt 2 and is conveyed from the receiving end to the discharge end of the conveyor belt 2. It should be noted that the wear-resistant plate 42 can be made of materials such as polyoxymethylene or polytetrafluoroethylene, as long as it has wear resistance, which will not be elaborated here.

[0044] Preferably, the sealing assembly 4 further includes a pressure regulating component 43. The pressure regulating component 43 has a first through hole, and the second mounting plate 412 has a first threaded hole. The pressure regulating component 43 is fixedly connected to the side wall of the second mounting plate 412 away from the conveyor belt 2 by bolts passing through the first through hole and engaging with the first threaded hole. The pressure of the second mounting plate 412 on the second mounting plate 412 can be adjusted by turning the bolts to prevent the pressure from being too high, which would cause the friction generated by the second mounting plate 412 pressing against the conveyor belt 2 to hinder the conveyor belt 2 from conveying the bulk material 100. It also prevents the pressure from being too low, which would cause a gap to be generated between the second mounting plate 412 and the conveyor belt 2, causing some of the bulk material 100 to fall between the conveyor belt 2 and the roller 3 through the gap between the second mounting plate 412 and the conveyor belt 2.

[0045] Continue as Figures 1 to 3 As shown, the bulk material conveying device also includes a first idler roller 5. The shaft of the first idler roller 5 is rotatably connected to the frame 1. The first idler roller 5 is used to support the conveyor belt 2, thereby reducing the sagging of the conveyor belt 2 and the deformation of the conveyor belt 2 caused by the weight of the bulk material 100. Specifically, the first idler roller 5 includes a main support roller 51 and an auxiliary support roller 52. The shafts of the main support roller 51 and the auxiliary support roller 52 are rotatably connected to the frame 1, respectively. The two auxiliary support rollers 52 are symmetrically arranged on both sides of the main support roller 51. The central axis of the main support roller 51 intersects with the central axis of the auxiliary support roller 52. The main support roller 51 and the auxiliary support roller 52 jointly support the conveyor belt 2, thereby providing more stable support for the conveyor belt 2 and reducing the sagging of the conveyor belt 2 and the deformation of the conveyor belt 2 caused by the weight of the bulk material 100.

[0046] In some embodiments, at least two first idlers 5 are disposed at the receiving end to prevent the receiving end of the conveyor belt 2 from being sagged or deformed by biased receiving impact when the loose material 100 falls onto the conveyor belt 2.

[0047] Continue as Figures 1 to 3 As shown, the auxiliary bearing roller 52 is also provided with a first limiting flange 521 at the end away from the main bearing roller 51. The first limiting flange 521 is used to limit the maximum offset distance of the conveyor belt 2 along its width direction, thereby preventing the conveyor belt 2 from being too offset along its width direction and causing the conveyor belt 2 to fall off the roller 3.

[0048] In some embodiments, the bulk material conveying device 100 further includes a second idler roller 6. The shaft of the second idler roller 6 is rotatably connected to the frame 1. The second idler roller 6 is used to support the conveyor belt 2. Both ends of the second idler roller 6 are provided with second limiting flanges 61. The second limiting flanges 61 are used to limit the maximum offset distance of the conveyor belt 2 along its width direction, thereby preventing the conveyor belt 2 from deviating too much along its width direction and causing the conveyor belt 2 to fall off the roller 3. It should be noted that for the receiving end of the conveyor belt 2, which bears the biased impact load, the first idler roller 5 can be set to focus on strengthening the stability of the receiving end. For the discharge end or other positions of the conveyor belt 2, which do not directly bear the biased impact load, the second idler roller 6 can be set to support the conveyor belt 2. Thus, the first idler roller 5 and the second idler roller 6 are used in combination to balance economic cost and the supporting effect of the idler rollers.

[0049] Figure 4 It shows Figure 1 A cross-sectional view of roller 3. (See diagram below.) Figure 4 Combination Figure 1 As shown, both ends of the roller 3 are provided with a third limiting flange 31. The third limiting flange 31 is used to limit the maximum offset distance of the conveyor belt 2 along its width direction, thereby preventing the conveyor belt 2 from deviating too much along its width direction and causing the conveyor belt 2 to fall off the roller 3.

[0050] Figure 5 It shows Figure 1 A cross-sectional view of the positioning wheel at point 7. (See diagram below.) Figure 5 Combination Figure 1 As shown, the bulk material conveying device also includes a positioning wheel 7. The shaft of the positioning wheel 7 is rotatably connected to the frame 1. The wheel surface of the positioning wheel 7 is used to press against the conveyor belt 2, thereby further preventing the conveyor belt 2 from deviating from its conveying trajectory. It should be noted that when the conveyor belt 2 conveys the bulk material 100, the positioning wheel 7 also rotates accordingly to prevent the positioning wheel 7 or the conveyor belt 2 from wearing out due to long-term friction.

[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
