Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, and in particular to a long-distance conveying equipment with adjustable material stop spacing. Background Technology

[0002] In material transportation operations in mining, building materials, chemical, and grain industries, long-distance conveying equipment is the core equipment for realizing continuous and efficient material transfer. Such equipment usually needs to complete the transfer of materials in different forms, such as granules, lumps, and powders, over a conveying path that is tens to hundreds of meters long. As a key component of conveying equipment, the main function of the material blocking device is to prevent materials from falling off the sides of the conveyor belt due to centrifugal force, vibration or changes in conveying angle during the conveying process, thus ensuring the stability of the conveying process and the material utilization rate. However, when the material blocking devices of existing long-distance conveying equipment are designed for conveying materials in different scenarios, if the spacing is designed for large materials, gaps are likely to occur when conveying small particles, resulting in material loss and environmental pollution. If the spacing is designed for small particles, large or agglomerated materials are likely to get stuck between the baffle and the conveyor belt, which not only hinders the conveying process, but may also cause wear on the conveyor belt or overload damage to the motor due to excessive friction. Therefore, this utility model provides a long-distance conveying device with adjustable material spacing. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a long-distance conveying device with adjustable material spacing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a long-distance conveying device with adjustable material spacing, including a support frame and a spacing adjustment component. The spacing adjustment component includes a bracket fixedly connected to the support frame, a horizontal plate fixedly connected to the top of the bracket, a sliding plate slidably connected to the outer side of the horizontal plate, a rotating shaft rotatably connected to the outer side of the sliding plate, and a connecting rod rotatably connected to the outer side of the rotating shaft. A drive limiting assembly includes a limiting rod fixedly connected to a horizontal plate, and a coupling is rotatably connected to the outer side of the connecting rod.

[0005] In a preferred embodiment, a cylinder is mounted on the outer side of the bracket, and the drive end of the cylinder is fixedly connected to the slide plate.

[0006] In a preferred embodiment, a conveying roller is fixedly connected to the outer side of the rotating shaft.

[0007] In a preferred embodiment, a limiting plate is slidably connected to the outer side of the limiting rod, and the outer side of the limiting plate is rotatably connected to the conveying roller.

[0008] In a preferred embodiment, the inner side of the slide plate is provided with a sliding groove that is adapted to the limiting rod.

[0009] In a preferred embodiment, the two ends of the connecting rod are rotatably connected to a rotating shaft and a coupling via bearings, respectively.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention utilizes the extension and retraction of a cylinder piston rod to drive a coupling that flexibly transmits thrust to a sliding plate. The sliding plate slides along the horizontal guide rail of the transverse plate with low friction, thereby driving the rotating shaft to translate and causing the connecting rod to swing around the rotating shaft, converting the horizontal displacement into angular displacement. Ultimately, this causes the conveying roller to move slightly up and down and swing within the vertical plane with the limit rod as a reference. Simultaneously, the limit plate slides along the limit rod to absorb radial loads. This design achieves stepless adjustment of the material stop spacing, and the flexible connection compensates for errors, while the dual guidance ensures stability. The conveying roller combines the functions of a hinge support and a roller, simplifying the structure and allowing adjustment to be completed without stopping the machine. This solves the problems of material leakage and jamming when conveying materials of different specifications using fixed-spacing material stop devices. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] like Figure 1 , Figure 2 and Figure 4 As shown, this embodiment provides a technical solution: a long-distance conveying device with adjustable material stop spacing, including a support frame 1 and a spacing adjustment component 2. The spacing adjustment component 2 includes a bracket 21 fixedly connected to the support frame 1. A horizontal plate 22 is fixedly connected to the top of the bracket 21. A sliding plate 23 is slidably connected to the outer side of the horizontal plate 22. A rotating shaft 24 is rotatably connected to the outer side of the sliding plate 23. A connecting rod 25 is rotatably connected to the outer side of the rotating shaft 24. Support frame 1 efficiently transfers all self-weight, material weight, and potential impact loads to the ground or platform in a single operation, ensuring effective control of structural deflection and maintaining overall stability even over long spans. Meanwhile, bracket 21 elevates the horizontal plate 22 to the required working height for the operator and works closely with support frame 1 to form a stable triangular rigid node. This design not only enhances the overall structural stability but also makes height adjustments flexible and convenient. By modularly adding or removing shims, it can easily adapt to different bandwidths or unloading heights without replacing the entire support system, greatly improving the equipment's adaptability and efficiency. The horizontal plate 22... The horizontal reference guide rail mainly serves to support the slide plate 23 and provide it with a smooth linear sliding pair. The surface of the horizontal plate 22 is processed in one step to ensure its flatness and precision. The slide plate 23 converts the linear thrust into the opening and closing displacement of the baffle plate through the actuation structure of the cylinder 32. This conversion process is simple and efficient, requiring only a low-friction slider and linear bearing, which greatly reduces maintenance points and maintenance costs. The rotating shaft 24 is located at the center of the hinge. Its unique design enables the connecting rod 25 and the conveying roller 34 to form a compound motion of rotation and sliding. The function of the connecting rod 25 is to amplify or turn the horizontal displacement of the slide plate 23 into the swing angle displacement of the baffle plate, thereby realizing the stepless adjustment of the baffle plate spacing to meet the usage requirements under different working conditions. like Figure 1 - Figure 3As shown, the drive limiting assembly 3 includes a limiting rod 31 fixedly connected to the horizontal plate 22, and a coupling 33 rotatably connected to the outer side of the connecting rod 25. A cylinder 32 is mounted on the outer side of the bracket 21, and the driving end of the cylinder 32 is fixedly connected to the slide plate 23. A conveying roller 34 is fixedly connected to the outer side of the rotating shaft 24. A limiting plate 35 is slidably connected to the outer side of the limiting rod 31, and the outer side of the limiting plate 35 is rotatably connected to the conveying roller 34. The limiting rod 31 provides a second-stage linear guide for the limiting plate 35, effectively absorbing the radial load of the conveying roller 34, preventing deformation of the cantilever structure, and further improving the overall structural stability. The cylinder 32, as the power source for spacing adjustment, flexibly connects the piston rod of the cylinder 32 to the slide plate 23 through the coupling 33. This design not only compensates for possible errors during installation but also effectively addresses thermal expansion issues, avoiding jamming that may occur with rigid connections, and ensuring long-term stable operation of the equipment. The conveying roller 34 plays a dual role in this system, serving as both a rotating hinge support for the baffle plate and an idler for the belt or chain plate, greatly simplifying the structure and reducing costs. The limiting plate 35 strictly constrains the circumferential motion of the roller within the vertical plane, ensuring the accuracy of the motion. At the same time, as the final mounting seat for the baffle plate, it provides stable support, ensuring that the baffle plate maintains a stable working state under various working conditions.

[0015] Working principle: like Figure 1 - Figure 4 As shown: In use: First, the piston rod of cylinder 32 extends and retracts linearly under the action of compressed air. Then, the thrust is flexibly transmitted to slide plate 23 through coupling 33, which drives slide plate 23 to slide linearly with low friction along the horizontal guide rail of cross plate 22. When slide plate 23 slides, its front end rotating shaft 24 moves horizontally, which in turn drives connecting rod 25 to swing around rotating shaft 24, thus converting horizontal displacement into angular displacement. This drives conveying roller 34 to make slight lifting and swinging in the vertical plane with limit rod 31 as the reference. While conveying roller 34 swings, its outer peripheral limit plate 35 slides linearly along limit rod 31 for a second stage, thus absorbing the radial load and impact transmitted by the roller, thereby keeping the baffle plate always within the working trajectory and realizing deviation during long-distance conveying. Conveying roller 34 acts as both a rotating hinge support and a belt idler, and then transmits the swing angle change of the baffle plate to the edge of the belt in real time, so that the spacing adjustment can be completed without stopping the machine, thereby enabling the entire conveyor line to quickly adapt to materials of different widths.

[0016] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
