Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, specifically to an improved device for a rotary lifting conveyor line in a crushing silo. Background Technology

[0002] The rotary lifting conveyor system for crushing silos is a specialized heavy-duty conveying equipment adapted to crushing and storage conditions, integrating material conveying and direction reversing functions. It mainly consists of wear-resistant conveyor units, a lifting drive mechanism, a slewing bearing and a rotary drive mechanism, and a reinforced support frame. It is typically located at the bottom discharge station of the crushing silo, receiving blocky materials discharged from the silo. According to the process requirements, the lifting mechanism can raise the conveying section and the carried material as a whole. The rotation mechanism drives the preset angle of conveying direction adjustment. After the lifting and lowering, the material can be conveyed along the reversing path to the corresponding crusher or downstream process. It can realize the connection of a single set of equipment to multiple crushing stations or discharge lines, reducing material transfer links, and is suitable for the heavy-duty, high-dust, and highly abrasive operation characteristics of crushing scenarios.

[0003] When the rotary lifting conveyor line device of the crushing silo is working, under normal conditions, the wear-resistant conveying section directly receives the block material discharged from the crushing silo and transfers the material to the corresponding processing station along the initial conveying direction. When it is necessary to switch the material conveying path, the lifting mechanism drives the slewing bearing and the upper conveying unit to lift as a whole, so that the conveying section and the material being carried are simultaneously removed from the original support reference. Then, the rotary drive mechanism drives the slewing bearing to rotate, and after rotating to the preset angle according to the process requirements, it is locked in position. The lifting mechanism returns to its original position, and the conveyor line falls back to the support surface and starts to operate, conveying the material to the target crusher or downstream line in the adjusted direction.

[0004] The existing rotary lifting conveyor line in the crushing silo still has many areas that need to be improved under the conditions of high dust and limited space. The lifting mechanism has limited resistance to eccentric loads and is prone to uneven stress during operation, which will accelerate the wear of components with long-term use. At the same time, the protective configuration during the carbon block reversal process is not complete, the material posture stability is insufficient, and there is a risk of slippage, which has a certain impact on material loss control and on-site operation safety. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide an improved device for a rotary lifting conveyor line of a crushing silo, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an improved device for a rotary lifting conveyor line of a crushing silo, comprising a support base, a drive motor disposed inside the support base, and a second positioning plate fixedly connected to the output end of the drive motor; a first positioning plate movably mounted on the upper part of the support base, and connecting plates fixed at both ends of the first positioning plate; a limit plate disposed above the connecting plate; multiple sets of rollers disposed between the two sets of limit plates; multiple sets of electric push rods fixed on the top surface of the second positioning plate; the lifting end of the electric push rod connected to the mounting base of the roller; and a fixing plate disposed on the top surface of the limit plate.

[0007] By adopting the above technical solution, through the rotary drive structure composed of the support base, drive motor, first positioning plate, and second positioning plate, when the drive motor drives the second positioning plate to rotate, the first positioning plate can move synchronously and provide stable support to the connecting plates on both sides. This effectively improves the structural coaxiality and load-bearing rigidity during rotation, significantly enhances the equipment's resistance to eccentric loads, avoids problems such as one-sided tilting and uneven force during lifting and rotation, reduces abnormal wear of mechanical parts, and extends the overall service life of the equipment. Combined with multiple sets of electric push rods synchronously driving the roller conveyor unit to complete the lifting action, it can ensure uniform force during the lifting process, improve the stability and reliability of the lifting operation under heavy load conditions, and better adapt to high-powder crushing silos. In dusty, high-load operating environments, the conveying platform, composed of a limit plate and multiple sets of rollers, provides stable support for the charcoal blocks. Combined with the fixing plate on top of the limit plate, it provides reliable physical restraint on the sides of the charcoal blocks during material reversal, effectively correcting the material's posture and preventing the charcoal blocks from sliding, tilting, or falling. This reduces material loss and improves the safety factor of on-site operations. At the same time, the limit plate and connecting plate adopt a movable sleeve assembly method, which, together with the adjusting block, allows for flexible adjustment of the adaptation size of the conveying station. With the precise limiting cooperation of the protrusion and the contact plate, the positioning accuracy and smooth operation of the conveying platform can be further improved, ensuring continuous and stable operation of the charcoal blocks during longitudinal to lateral reversal.

[0008] The present invention is further configured such that the first positioning plate and the support base are rotatably connected by a bearing.

[0009] Preferably, the rotational engagement between the first positioning plate and the support base is achieved through a bearing, which can effectively reduce rotational friction resistance, improve the smoothness of rotational movement, and reduce component wear.

[0010] The present invention is further configured such that the limiting plate is sleeved on the top of the connecting plate, and the limiting plate and the connecting plate are movably connected.

[0011] Preferably, the limiting plate and the connecting plate adopt a movable sleeve structure, which facilitates assembly, debugging and subsequent maintenance and disassembly, effectively improving the assembly flexibility and maintenance convenience of the structure.

[0012] The present invention is further configured such that multiple sets of electric push rods are symmetrically distributed along the top surface of the second positioning plate.

[0013] Preferably, multiple sets of electric push rods are symmetrically distributed on the top surface of the second positioning plate, which can ensure that the force is uniform and consistent during the lifting process, and improve the stability and anti-eccentric load capacity of the lifting operation.

[0014] The present invention is further configured such that multiple sets of rollers are arranged in parallel at intervals along the length direction of the limiting plate.

[0015] Preferably, multiple sets of rollers are arranged in parallel intervals along the length direction to form a continuous and uniform conveying bearing surface, ensuring stable support during the conveying of carbon blocks and avoiding uneven local stress.

[0016] The present invention is further configured such that the fixing plate extends along the length direction of the limiting plate and is vertically arranged on the side of the roller.

[0017] Preferably, a fixed plate extending along the length direction is vertically arranged on the side of the roller, which can form a lateral enclosure constraint on the carbon blocks during the conveying and reversing process to prevent the material from sliding and falling.

[0018] The present invention is further configured such that the drive motor is coaxially fixed in the central cavity of the support base.

[0019] Preferably, the drive motor is coaxially fixed in the central cavity of the support base, which can ensure the coaxial output of the rotational driving force, improve the rotational positioning accuracy, and optimize the structural compactness.

[0020] The present invention is further configured such that the first positioning plate and the second positioning plate are arranged coaxially, and the two sets of connecting plates are symmetrically fixed on opposite sides of the first positioning plate.

[0021] Preferably, the first positioning plate and the second positioning plate are arranged coaxially, and together with the two sets of symmetrically arranged connecting plates, the overall force balance during the rotation process can be ensured, thereby improving the structural bearing stiffness and operational stability.

[0022] The present invention is further configured such that a protrusion is provided at the bottom of the limiting plate, and a contact plate is provided on the outer wall of the connecting plate, wherein the protrusion is in contact with the outer wall of the contact plate.

[0023] Preferably, the protrusion at the bottom of the limiting plate fits into the contact plate on the outer wall of the connecting plate, which can precisely limit the relative position of the two and improve the assembly positioning accuracy of the conveying platform.

[0024] The present invention is further configured such that adjusting blocks are provided at both ends of the roller, and the adjusting blocks are assembled at the bottom of the roller.

[0025] Preferably, adjusting blocks are provided at both ends of the roller, which can flexibly adjust the installation position of the roller and the effective width of the conveying station to adapt to the transfer needs of materials of different sizes and specifications.

[0026] In summary, the present invention has the following main beneficial effects:

[0027] 1. This invention utilizes a rotary drive structure composed of a support base, a drive motor, a first positioning plate, and a second positioning plate. When the drive motor rotates the second positioning plate, the first positioning plate moves synchronously and provides stable support to the connecting plates on both sides. This effectively improves the structural coaxiality and load-bearing rigidity during rotation, significantly enhances the equipment's resistance to eccentric loads, avoids problems such as one-sided tilting and uneven force during lifting and rotation, reduces abnormal wear of mechanical parts, and extends the overall service life of the equipment. Furthermore, by cooperating with multiple sets of electric push rods to synchronously drive the roller conveyor unit to complete the lifting action, it ensures uniform force during the lifting process, improves the stability and reliability of lifting operations under heavy load conditions, and better adapts to the high-dust, high-load working environment of the crushing silo.

[0028] 2. This invention utilizes a conveying platform composed of a limiting plate and multiple sets of rollers to provide stable support for the charcoal blocks. Combined with a fixing plate on top of the limiting plate, it provides reliable physical restraint on the sides of the charcoal blocks during material reversal, effectively correcting the material's posture and preventing the charcoal blocks from sliding, tilting, or falling. This reduces material loss and improves the safety factor of on-site operations. Furthermore, the limiting plate and connecting plate are assembled using a movable sleeve, allowing for flexible adjustment of the conveying station's dimensions with the help of adjusting blocks. The precise limiting action of the protrusions and contact plates further enhances the positioning accuracy and smooth operation of the conveying platform, ensuring continuous and stable operation during the longitudinal to lateral reversal of the charcoal blocks.

[0040] First embodiment: An improved device for a rotary lifting conveyor line of a crushing silo, please refer to [link / reference]. Figures 1-7The system includes a support base 1, inside which is installed a drive motor 4. A second positioning plate 5 is fixedly connected to the output end of the drive motor 4. A first positioning plate 2 is movably mounted on the upper part of the support base 1, and connecting plates 3 are fixed to both ends of the first positioning plate 2.

Through the rotary drive structure composed of the support base 1, drive motor 4, first positioning plate 2, and second positioning plate 5, when the drive motor 4 drives the second positioning plate 5 to rotate, the first positioning plate 2 can move synchronously and provide stable support to the connecting plates 3 on both sides. This effectively improves the structural coaxiality and load-bearing rigidity during rotation, significantly enhances the equipment's resistance to eccentric loads, avoids problems such as one-sided tilting and uneven force during lifting and rotation, reduces abnormal wear of mechanical parts, and extends the overall service life of the equipment. With a long service life, the conveying unit, in conjunction with multiple sets of electric push rods 6, synchronously drives rollers 7 to complete the lifting action, ensuring uniform force during the lifting process, improving the stability and reliability of the lifting operation under heavy load conditions, and better adapting to the high dust and heavy load working environment of the crushing silo.

With the precise limit cooperation of the protrusion 11 and the contact plate 12, the positioning accuracy and smooth operation of the conveying platform can be further improved, ensuring the continuous and stable operation of the longitudinal to lateral reversal operation of the charcoal blocks.

[0044] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-7 Multiple sets of rollers 7 are arranged parallel to each other along the length of the limiting plate 8.

The protrusion 11 at the bottom of the limiting plate 8 and the contact plate 12 on the outer wall of the connecting plate 3 are in contact with each other, which can form a precise limit on the relative position of the two and improve the assembly positioning accuracy of the conveying platform.

[0049] Second embodiment: Please refer to Figure 1 The difference between Embodiment 2 and Embodiment 1 is that, while retaining Embodiment 1, adjustment blocks 10 are added to both ends of the roller 7. The adjustment blocks 10 can limit and adjust the installation position of the roller 7 at both ends of the device, so that the conveying station can adapt to the transfer needs of materials of different sizes within a certain range, effectively broadening the applicable scenarios of the equipment and improving the practical performance of the device.

[0050] In practical operation, this invention:

[0051] After the charcoal material discharged from the crushing silo enters the device, it is carried by a conveying unit consisting of multiple sets of rollers 7 and is conveyed smoothly along the initial longitudinal direction. The support base 1 serves as the bearing base of the entire equipment and provides rigid support for the upper conveying structure through the connecting plate 3. The limiting plate 8 and the fixing plate 9 form initial constraints on the material in the lateral direction to ensure the stability of the material's posture during the conveying process. At this time, the drive motor 4 and the electric push rod 6 are both in standby mode, and the material can be continuously transferred to the reversing station through the conveying unit.

[0052] When the longitudinal to transverse direction of the charcoal blocks needs to be changed, multiple sets of electric push rods 6 are lifted synchronously, driving the roller 7 conveying unit and the charcoal blocks above to lift up, so that the material is separated from the original conveying support surface; then the drive motor 4 starts, and outputs the rotation torque through the second positioning plate 5, driving the first positioning plate 2, the connecting plate 3 and the entire upper conveying structure to rotate synchronously, and lock precisely at the preset position; after the change of direction is completed, the electric push rods 6 fall back to reset, the roller 7 conveying unit restarts operation, and conveys the charcoal blocks to the downstream crushing station along the adjusted transverse direction;

[0053] Throughout the material conveying and reversing process, the lateral protection structure composed of the limiting plate 8 and the fixing plate 9 continuously forms a barrier to constrain the carbon blocks, effectively preventing the material from slipping and falling due to posture deviation, reducing material loss and improving on-site operation safety. In the second embodiment, the adjustment blocks 10 added to both ends of the roller 7 can flexibly adjust the effective width of the conveying station, allowing the device to adapt to the transfer of carbon blocks of different sizes and specifications within a certain range. With the precise limiting cooperation of the protrusion 11 and the contact plate 12, the positioning accuracy and working condition adaptability of the equipment operation are further improved, and it can better adapt to the high dust and heavy load working environment of the crushing silo.

[0054] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the invention and are not intended to limit it. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
