Description

Technical Field

[0001] This utility model belongs to the field of material conveying technology, and more specifically, it relates to a hydraulically driven tilting and unloading device. Background Technology

[0002] In modern industrial production, the material conveying and unloading processes play a crucial role in production efficiency and product quality. Especially in scenarios requiring the tipping of containers to unload materials, traditional unloading methods often rely on manual handling or simple mechanical assistance. Manual operation is not only inefficient but also labor-intensive and poses significant safety hazards, making it difficult to meet the demands of large-scale, automated production.

[0003] Existing mechanical feeding devices often employ a single drive structure or a complex transmission system to achieve container tilting. A single drive structure struggles to guarantee the stability and reliability of tilting when dealing with containers of varying weights and sizes, easily leading to incomplete or excessive tilting, resulting in material spillage and container damage. While complex transmission systems can improve tilting accuracy to some extent, their intricate structure and numerous components increase manufacturing costs and maintenance complexity, and are prone to production interruptions and reduced efficiency due to component wear and malfunctions. Utility Model Content

[0004] The purpose of this invention is to provide a hydraulically driven tilting and unloading device to solve the problems of poor tilting stability and reliability, as well as complex structure.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a hydraulically driven tilting and unloading device, comprising:

[0006] Frame assembly;

[0007] A conveying and tilting mechanism, comprising a tilting frame, the tilting frame being mounted on the top of the frame assembly via a rotating shaft, and a conveying component for conveying a container filled with materials on the tilting frame.

[0008] Two drive mechanisms are respectively disposed on both sides of the frame assembly. Each drive mechanism includes a hydraulic cylinder, a drive gear plate, and a drive gear. The hydraulic cylinder is disposed on one side of the frame assembly, and the drive gear is connected to the upper end of the hydraulic cylinder. The drive gear is rotatably disposed on the frame assembly and connected to the rotating shaft. The drive gear plate meshes with the drive gear. The hydraulic cylinder drives the drive gear to rotate through the drive gear plate, thereby causing the tilting frame to tilt.

[0009] In one possible implementation, the framework assembly includes:

[0010] Two support frames are arranged symmetrically, the conveying and flipping mechanism is located on the top of the two support frames, and the driving mechanism is located on the outside of the support frames;

[0011] Several reinforcing beams are connected at the lower part between the two support frames.

[0012] In one possible implementation, the support frame has several weight-reducing holes, the bottom of the support frame is provided with pads, and reinforcing ribs are provided between the reinforcing beam and the support frame.

[0013] In one possible implementation, the flipping frame includes:

[0014] Two conveying beams are respectively arranged parallel to each other at the upper end of the frame assembly, the rotating shaft is arranged at the lower end of the conveying beams, and the transmission assembly is arranged on the conveying beams;

[0015] A connecting beam is vertically connected between the two conveying crossbeams.

[0016] In one possible implementation, the transmission component includes:

[0017] Multiple conveyor rollers are arranged to rotate sequentially along the length of the conveyor beam.

[0018] A conveyor motor is fixed to one end of the conveyor beam. The conveyor motor is connected to multiple conveyor rollers via chain drive and is used to drive the multiple conveyor rollers to rotate synchronously.

[0019] In one possible implementation, a limit block is provided at one end of the upper surface of the conveying beam.

[0020] In one possible implementation, the connecting beam has an arc-shaped concave surface at its center.

[0021] In one possible implementation, a slide rail is longitudinally arranged on one side of the frame assembly, and the drive tooth plate is slidably disposed within the slide rail.

[0022] In one possible implementation, an auxiliary gear is rotatably mounted on one side of the frame assembly, the auxiliary gear being located below the drive gear and meshing with the drive gear plate.

[0023] In one possible implementation, a protective cover is provided on one side of the frame assembly, and the drive gear plate, the drive gear, and the auxiliary gear are all located inside the protective cover.

[0024] The beneficial effects of the hydraulically driven tilting and unloading device provided by this utility model are as follows: Compared with the prior art, the device adopts two drive mechanisms symmetrically arranged on both sides of the frame assembly. The hydraulic cylinder in each drive mechanism is driven by the meshing of the drive gear and the drive tooth plate, converting the linear motion of the hydraulic cylinder into the rotational motion of the drive gear, thereby driving the tilting frame to tilt. The dual-side synchronous drive method can provide a more balanced driving force compared with a single drive structure, ensuring that the tilting frame is subjected to uniform force during the tilting process. Even when facing containers of different weights and sizes containing materials, it can maintain stable tilting and avoid instability such as tilting and jamming, greatly improving the stability and reliability of tilting. At the same time, the meshing transmission of the drive tooth plate and the drive gear has high transmission accuracy and reliability, reducing the problem of incomplete or excessive tilting caused by transmission errors, further ensuring the accuracy and stability of the unloading process. This device adopts a transmission method of hydraulic cylinder, drive tooth plate, and drive gear. The hydraulic cylinder, as the power source, is directly connected to the drive tooth plate and drives the rotating shaft through gear meshing. The structure is compact and the number of parts is greatly reduced. Compared to traditional complex transmission systems, this invention not only reduces the manufacturing cost of the equipment but also decreases the number of maintenance points due to the reduced number of components, thus lowering maintenance difficulty and costs. The hydraulically driven tilting unloading device provided by this invention improves the reliability and stability of equipment operation and effectively solves the problem of complex structures in traditional unloading devices.

[0033] Please see Figures 1 to 3 This invention provides a hydraulically driven tilting and unloading device. The device includes a frame assembly, a conveying and tilting mechanism, and two drive mechanisms. The conveying and tilting mechanism includes a tilting frame, which is mounted on the top of the frame assembly via a rotating shaft 12. The tilting frame is equipped with a conveying component for transporting containers filled with materials. The two drive mechanisms are respectively located on both sides of the frame assembly. Each drive mechanism includes a hydraulic cylinder 13, a drive gear plate 14, and a drive gear 15. The hydraulic cylinder 13 is located on one side of the frame assembly, and the drive gear 15 is connected to the upper end of the hydraulic cylinder 13. The drive gear 15 is rotatably mounted on the frame assembly and connected to the rotating shaft 12. The drive gear plate 14 meshes with the drive gear 15, and the hydraulic cylinder 13 drives the drive gear 15 to rotate via the drive gear plate 14, thereby tilting the tilting frame.

[0034] This utility model provides a hydraulically driven tilting and unloading device. Compared with the prior art, the device uses two drive mechanisms symmetrically arranged on both sides of the frame assembly. The hydraulic cylinder 13 in each drive mechanism is driven by the meshing of a drive gear plate 14 and a drive gear 15, converting the linear motion of the hydraulic cylinder 13 into the rotational motion of the drive gear 15, thereby driving the tilting frame to tilt. This dual-side synchronous drive method provides a more balanced driving force compared to a single drive structure, ensuring uniform force on the tilting frame during tilting. Even when faced with containers of different weights and sizes containing materials, it can maintain stable tilting, avoiding instability such as tilting or jamming, greatly improving the stability and reliability of tilting. Simultaneously, the meshing transmission between the drive gear plate 14 and the drive gear 15 has high transmission accuracy and reliability, reducing problems of incomplete or excessive tilting caused by transmission errors, further ensuring the accuracy and stability of the unloading process. This device uses a transmission method involving hydraulic cylinders 13, drive gear plates 14, and drive gears 15. The hydraulic cylinder 13, serving as the power source, is directly connected to the drive gear plate 14, driving the rotating shaft 12 through gear meshing. This results in a compact structure and a significant reduction in the number of parts. Compared to traditional complex transmission systems, this not only reduces manufacturing costs but also decreases maintenance points due to the reduced number of components, thus lowering maintenance difficulty and costs. The hydraulically driven tilting unloading device provided by this invention improves the reliability and stability of equipment operation and effectively solves the problem of complex structures in traditional unloading devices.

[0035] The frame assembly includes two support frames 1 and several reinforcing beams 2. The two support frames 1 are symmetrically arranged, providing a stable mounting foundation for the conveying and tilting mechanism and the drive mechanism. This symmetrical structure ensures more balanced force distribution throughout the device, effectively dispersing the gravity and driving force generated during the tilting process, preventing localized stress concentration, greatly enhancing the stability of the device during operation, and ensuring the safety and reliability of the tilting and unloading process. Several reinforcing beams 2 connect the lower part between the two support frames 1.

[0036] Please see Figure 2 The support frame 1 has several weight-reducing holes 3, which effectively reduce the overall weight of the device. Without compromising the strength and rigidity of the support frame 1, this reduces material usage and manufacturing costs. The bottom of the support frame 1 is equipped with pads 4, which effectively isolate the device from uneven ground or vibrations, enhancing its stability. Reinforcing ribs 5 are installed between the reinforcing beam 2 and the support frame 1, significantly enhancing the structural strength and rigidity of the connection. The reinforcing ribs 5 effectively disperse and transfer stress, preventing deformation or damage at the connection due to excessive force, further improving the overall stability and reliability of the frame assembly.

[0037] The tilting frame includes two conveying beams 6 and a connecting beam 10. The two conveying beams 6 are parallel to each other at the top of the frame assembly, ensuring that containers filled with materials remain stable during transport and preventing container swaying and material spillage due to beam tilting or unevenness, thus improving the safety and reliability of material transport. The rotating shaft 12 is located at the lower end of the conveying beams 6, making the rotation of the tilting frame smoother and reducing friction and resistance during tilting. Combined with the synergistic effect of the drive mechanisms on both sides, it can achieve precise and stable tilting actions, meeting the material unloading requirements under different working conditions. The connecting beam 10 is vertically connected between the two conveying beams 6, forming a stable frame structure that effectively resists the torsion and deformation of the frame by external forces. When bearing heavy objects or performing tilting operations, it ensures that the frame maintains a stable shape, preventing structural deformation from affecting the normal operation of the transport components.

[0038] The transmission assembly includes multiple conveyor rollers 7 and a conveyor motor 8. The multiple conveyor rollers 7 are arranged to rotate sequentially along the length of the conveyor beam 6, providing continuous and stable support and a transmission surface for containers filled with materials. Compared to a single transmission surface, multiple conveyor rollers 7 distribute the pressure on the containers, effectively preventing tilting or jamming due to uneven force during transmission, ensuring smooth container transport. The conveyor motor 8 is fixed to one end of the conveyor beam 6 and is connected to the multiple conveyor rollers 7 via chain drive, driving the rollers 7 to rotate synchronously. This transmission method has high transmission accuracy and reliability, ensuring consistent container speed during transmission and preventing misalignment or accumulation due to differences in roller speed, thus guaranteeing an orderly unloading process.

[0039] Please see Figure 2 and Figure 3 A limit block 9 is provided at one end of the upper surface of the conveying beam 6. The limit block 9 can effectively prevent containers filled with materials from rushing out of the conveying beam 6 during the transmission process due to inertia, external impact, or excessive conveying speed. When the container is conveyed to the predetermined position for tipping and unloading, the limit block 9 can stop the container in time to avoid accidental slippage, material spillage, container damage, or even safety accidents, greatly improving the safety and reliability of the equipment operation.

[0040] Please see Figure 3 The connecting beam 10 has an arc-shaped concave surface 11 in the middle, which is adapted to the outer wall of the container holding the material, so as to ensure the stability of the container during the tipping and unloading process.

[0041] Please see Figure 2 and Figure 3A slide rail 16 is longitudinally arranged on one side of the frame assembly. The slide rail 16 is bolted to the frame assembly, and the drive gear plate 14 is slidably disposed within the slide rail 16. The slide rail 16 provides motion guidance for the drive gear plate 14, ensuring that the drive gear plate 14 can only slide linearly along the direction of the slide rail 16 under the push of the hydraulic cylinder 13, effectively limiting any possible deviation or wobbling during movement. This ensures that the drive gear plate 14 and the drive gear 15 always maintain a stable and reliable meshing state, avoiding poor gear meshing due to gear plate movement deviation, thereby ensuring the accuracy and stability of the drive gear 15 rotation. Ultimately, this allows the tilting frame to precisely tilt according to a predetermined trajectory and angle, improving the accuracy and reliability of the unloading operation.

[0042] Please see Figure 2 An auxiliary gear 17 is rotatably mounted on one side of the frame assembly. Located below the drive gear 15, the auxiliary gear 17 meshes with the drive gear plate 14, forming a stable double-meshing structure. When the hydraulic cylinder 13 pushes the drive gear plate 14, the auxiliary gear 17 shares some of the force on the drive gear plate 14, effectively preventing it from shifting or wobbling during operation and ensuring that the drive gear plate 14 and drive gear 15 maintain good meshing. This stable meshing relationship makes the tilting frame more evenly stressed and runs more smoothly during tilting. Even with material containers of different weights and sizes, it ensures the accuracy and reliability of the tilting action, greatly improving the stability and safety of the unloading operation.

[0043] In addition, after the auxiliary gear 17 engages in meshing, it disperses the originally concentrated force to multiple meshing points, reduces the force intensity per unit area, reduces frictional losses between components, extends the service life of the drive gear plate 14, drive gear 15 and auxiliary gear 17, and reduces the maintenance cost and replacement frequency of the equipment.

[0044] Please see Figure 1 and Figure 3 A protective cover 18 is provided on one side of the frame assembly, and the drive gear plate 14, drive gear 15, and auxiliary gear 17 are all located inside the protective cover 18. The protective cover 18 effectively isolates the operator from direct contact with the high-speed rotating drive gear plate 14, drive gear 15, and auxiliary gear 17, greatly reducing the risk of mechanical injury caused by the operation of the components. During equipment operation, the meshing and rotation of gears and gear plates may cause parts to loosen or fly away. The protective cover 18 can block these potential dangers, creating a safe working environment for the operator and ensuring personal safety. At the same time, the protective cover 18 can also prevent foreign objects from entering the transmission component area, avoiding equipment failure or even safety accidents caused by foreign objects getting stuck, and ensuring stable operation of the equipment.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
