Description

Technical Field

[0001] This application relates to the field of sand casting technology, specifically to a vibratory conveyor for sand casting. Background Technology

[0002] Vibratory conveyors are widely used in sand casting, primarily for conveying and handling sand molds and other materials generated during the casting process. Traditional vibratory conveyors typically employ a simple linear vibrator and feed plate structure, with material transfer achieved through the drive of the vibrator. However, traditional vibratory conveyors suffer from several significant drawbacks in practical use, limiting their application in high-efficiency production environments.

[0003] Existing vibrating conveyors are typically only effective at transporting loose sand or small granular materials. However, they struggle to handle larger lumps, especially solidified sand blocks that may form during the casting process. This can easily lead to material accumulation or blockages during transport, affecting the continuity and efficiency of the production line.

[0004] Secondly, the lack of flexible adjustment capability is also a major problem with traditional vibrating conveyors. Due to the simple structural design of traditional equipment, the vibration amplitude and frequency are usually not flexibly adjustable. This makes it impossible for the equipment to adapt to the characteristics of different materials, making it difficult to meet diverse production needs. Especially when fine processing of materials is required, traditional equipment is inadequate, easily resulting in uneven crushing or failure to crush materials. Traditional vibrating conveyors usually lack effective protective measures and shock absorption designs, making them prone to damage due to mechanical fatigue or unstable vibration during long-term use, increasing maintenance costs and downtime. When handling high-hardness or large materials, the lack of a buffer mechanism in traditional equipment easily generates strong mechanical impacts, further aggravating equipment wear and failure.

[0005] To address the aforementioned problems, this invention provides an improved vibrating conveyor for sand casting. This equipment not only enhances its ability to crush large lumps of material through an innovatively designed agglomeration crushing mechanism, but also achieves flexible adjustment during the crushing process through the precise coordination of eccentric roller groups, washboard assemblies, and rolling components, adapting to the processing needs of different materials. Simultaneously, this invention introduces elastic bars and flexible block structures, effectively buffering vibrations and impacts during operation, extending the equipment's service life, and significantly improving production efficiency and equipment reliability. Through these improvements, this invention addresses the shortcomings of traditional vibrating conveyors while providing a more efficient, reliable, and adaptable material handling solution for sand casting, suitable for various complex casting production environments. Summary of the Invention

[0006] The purpose of this application is to provide an improved vibratory conveyor for sand casting, aiming to solve the problems of insufficient crushing capacity, unstable conveying, and inflexible equipment adjustment in the prior art. Through optimized design of the conveying and crushing structures, this invention significantly improves the working efficiency, adaptability, and durability of the equipment.

[0007] Therefore, the technical solution adopted by the present invention is: a vibratory conveyor for sand casting, comprising:

[0008] Conveyor Frame: A linear vibrator and a feed hopper are fixedly installed on the top surface of the conveyor frame. The output end of the linear vibrator is equipped with a feeding plate, which is used to smoothly convey the material from the bottom of the agglomeration crushing mechanism to the feed inlet of the feeding hopper. Through the vibration force generated by the linear vibrator, the material can move evenly on the feeding plate, thereby avoiding the accumulation or blockage of material during the conveying process.

[0009] Elevator: The elevator is used to lift and convey materials into the agglomeration crushing mechanism, achieving efficient material transfer. The elevator works in conjunction with the agglomeration crushing mechanism to ensure a continuous flow of materials into the crushing process, guaranteeing the stability and continuity of the production line.

[0010] Agglomerate crushing mechanism: The agglomerate crushing mechanism is fixedly installed on the top surface of the conveyor frame, with its bottom end facing the feeding plate. The agglomerate crushing mechanism conveys the crushed material from the bottom of the crushing hopper upwards to the feed inlet of the feeding hopper through the feeding plate, realizing the circulation and processing of materials.

[0011] In a preferred embodiment, the present invention can be further configured as follows:

[0012] Eccentric roller assembly and washboard assembly: The agglomerate crushing mechanism includes a crushing bucket, an eccentric roller assembly, a washboard assembly, a rolling assembly, and a first drive motor. The eccentric roller assembly drives the washboard assembly and the rolling assembly to oscillate eccentrically, causing the agglomerate material to be crushed layer by layer within the crushing bucket. The distance between the washboard assembly and the rolling assembly is dynamically adjusted through an intelligent control system and a flexible strip structure to ensure crushing efficiency.

[0013] In a preferred embodiment, the present invention can be further configured as follows:

[0014] Intelligent Control System and Adjustment Mechanism: The intelligent control system of this invention can adjust the distance between the rubbing plate assembly and the crushing assembly in real time according to the size and hardness of the material, achieving precise crushing of different materials. The combined design of the eccentric roller assembly and the flexible strip allows the rubbing plate assembly and the crushing assembly to flexibly adapt to the crushing requirements of different materials.

[0015] In a preferred embodiment, the present invention can be further configured as follows:

[0016] Wear-resistant liners and equipment durability: To extend the service life of the equipment, wear-resistant liners are installed on the inner side of the crushing bucket, which can effectively reduce the wear of high-hardness materials on the inner wall of the crushing bucket, reduce the maintenance frequency, and improve the long-term efficiency of the equipment.

[0017] Through the above technical solutions, the vibrating conveyor for sand casting of the present invention effectively solves the various shortcomings of traditional equipment when crushing large lumps of materials, significantly improves crushing efficiency and equipment adaptability, reduces maintenance requirements, extends equipment service life, and is particularly suitable for various complex casting production environments.

[0018] The beneficial effects achieved by this invention are as follows:

[0019] 1. This invention employs a combination of opposing rubbing plate assemblies and rolling assemblies. Driven by an eccentric roller assembly, the rotation of the eccentric block causes the rubbing plate and rolling assemblies to oscillate eccentrically. The rubbing plate assembly has uniformly distributed ribs on its surface, further enhancing the crushing effect. When the two rubbing plate assemblies move relative to each other, the ribs can apply sufficient compressive stress and shear force to the agglomerated material, thereby achieving efficient crushing and improving the efficiency and thoroughness of agglomerated material crushing.

[0020] 2. In this invention, with the assistance of the lifting conveyor, materials can be efficiently lifted and conveyed into the crushing bucket, where they are then crushed by the rubbing plate assembly and the crushing assembly. The distance between the rubbing plate assembly and the crushing assembly can be adjusted through eccentric swing and a flexible strip structure. By adjusting the position of each eccentric roller sleeve, precise swinging of the bottom end of the rubbing plate assembly can be achieved, thereby flexibly adjusting the crushing distance. This flexibility not only improves the crushing effect but also ensures the equipment's adaptability to different materials, reducing the need for equipment adjustment and maintenance.

[0021] 3. In this invention, the introduction of a flexible strip structure enables the corrugated plate assembly and the crushing assembly to have a certain degree of elastic adjustment capability during stress. When encountering large lumps of material, the flexible strip can absorb some of the stress through deformation, preventing damage to the equipment due to excessive hard impact, while also ensuring the uniformity of the crushing effect. In addition, the eccentric roller design makes the movement of the corrugated plate assembly and the crushing assembly more stable, reducing the problem of material deviation or uneven crushing caused by equipment vibration during the crushing process. This design not only improves the durability of the equipment but also enhances the safety and stability of the crushing operation. Attached Figure Description

[0032] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] This invention provides a vibratory conveyor for sand casting, aiming to solve the problems of insufficient crushing capacity, poor adjustment flexibility, and lack of effective protection in traditional vibratory conveyors when handling large lumps of material. The specific embodiments of this invention are described in detail below with reference to the accompanying drawings.

[0034] Example 1:

[0035] like Figures 1 to 7 As shown, the vibrating conveyor of the present invention mainly includes a conveyor frame 100, a lifting material conveyor 200, and a block crushing mechanism 300. The specific structure and working principle are as follows:

[0036] A linear vibrator 120 and a feed hopper 130 are fixedly installed on the top surface of the conveyor frame 100. The output end of the linear vibrator 120 is provided with a feeding plate 110, which is used to smoothly convey the material from the feed hopper 130 to the feed inlet of the agglomerate crushing mechanism 300. Through the vibration force generated by the linear vibrator 120, the material can move evenly on the feeding plate 110, thereby avoiding the accumulation or blockage of material during the conveying process.

[0037] The agglomeration crushing mechanism 300 is fixedly installed on the top surface of the conveyor frame 100, and its bottom end is arranged directly opposite the feeding plate 110. The material is conveyed to the inside of the agglomeration crushing mechanism 300 by the elevator 200, crushed in the crushing hopper 310, and then conveyed to the feed inlet of the feeding hopper 130 by the feeding plate 110.

[0038] The agglomerate crushing mechanism 300 includes a crushing bucket 310, an eccentric roller assembly 320, a rubbing plate assembly 330, a rolling assembly 340, and a first drive motor 350. Fixed seats 311 are fixedly installed on both sides of the crushing bucket 310, and the first drive motor 350 is fixed to the inner side of the fixed seats 311. Through the action of the drive motor 350, the various components in the crushing mechanism work together to achieve the crushing of agglomerate materials.

[0039] The number of washboard assemblies 330 is several and they are evenly divided into two groups. The two groups of washboard assemblies 330 are symmetrically arranged inside the crushing bucket 310. Each group of washboard assemblies 330 is installed by a shaft fixed inside the crushing bucket 310. The shaft is rotatably sleeved inside the shaft hole 333 on the washboard assembly 330, thereby realizing the flexible swing of the washboard assembly 330.

[0040] Each washboard assembly 330 includes a washboard body 331, a grinding rack 332, and a flexible block 335 embedded in and installed on the surface of the washboard body 331. The grinding rack 332 is movably installed on the surface of the washboard body 331, and one end of the flexible block 335 is fixedly connected to the surface of the grinding rack 332, so that when the washboard assembly 330 eccentrically swings, the grinding rack 332 can flexibly conform to the material and provide a stable crushing effect.

[0041] The eccentric roller assembly 320 includes an inner bushing 321, a key shaft 322, and a plurality of eccentric roller sleeves 323 rotatably fitted onto the surface of the inner bushing 321. The eccentric roller assembly 320 engages with the sleeve hole 334 on the washboard assembly 330 via the key shaft 322 to achieve eccentric oscillation of the washboard assembly 330.

[0042] The crushing assembly 340 includes a moving seat 341, a positioning block 342, and a spring bar 343 connecting the positioning block 342 and the moving seat 341. An eccentric block is fixedly connected to the output end of the first drive motor 350. The eccentric block drives the eccentric roller group 320 and the rubbing plate assembly 330 to perform eccentric motion through the moving seat 341, thereby realizing the crushing and crushing of lumpy materials.

[0043] During the crushing process, the spring bar 343 provides flexible deformation function, which can buffer mechanical vibration and impact during crushing, thereby effectively reducing equipment wear and extending equipment service life. In addition, a second drive motor 344 for driving the eccentric roller group 320 to rotate is fixedly installed on the surface of the motion seat 341, and the positioning block 342 is fixed to the inside of the crushing bucket 310 to ensure that the crushing assembly 340 remains stable during eccentric movement.

[0044] Work process and results:

[0045] During equipment operation, material is conveyed to the interior of the crushing bucket 310 via the lifting conveyor 200, where it is crushed by the crushing zone formed by the opposing rubbing plate assembly 330 and the crushing assembly 340. Driven by the first drive motor 350 and the eccentric roller group 320, the rubbing plate assembly 330 performs layer-by-layer compression and crushing of the material in eccentric oscillation, and the ridges on the surface of the grinding rack 332 further enhance the crushing effect.

[0046] The flexible oscillation of the washboard assembly 330 and the flexible adjustment of the crushing assembly 340 ensure that lumps of materials of different sizes and hardness can be effectively crushed. At the same time, the elastic bar structure 343 of the equipment reduces mechanical impact and provides a more stable working state, improving the smoothness and reliability of the entire crushing process.

[0047] Example 2:

[0048] This second embodiment, based on the first embodiment, further improves the adjustment mechanism of the agglomerate crushing mechanism, particularly enhancing the equipment's flexibility and crushing effect to meet the crushing requirements of different material sizes and hardnesses. This embodiment primarily optimizes the adjustment mechanisms of the washboard assembly 330 and the compaction assembly 340.

[0049] Coordination optimization of conveying and crushing:

[0050] In this embodiment, the elevator 200 efficiently conveys the material into the crushing bucket 310 via the feeding plate 110. After entering, the material is initially crushed by the rubbing plate assembly 330 and the crushing assembly 340. At this stage, the size and hardness of the material directly affect the crushing efficiency. Therefore, it is crucial to flexibly adjust the spacing between the crushing components according to the material characteristics.

[0051] Coordinated adjustment of the washboard assembly and the rolling assembly:

[0052] To accommodate materials of different sizes and hardnesses, this embodiment employs a collaborative adjustment mechanism. In this mechanism, the distance between the washboard assembly 330 and the rolling assembly 340 is adjusted not only by an intelligent control system but also by precise mechanical adjustment via the eccentric roller group 320.

[0053] The eccentric roller assembly 320 includes an inner bushing 321, a key shaft 322, and an eccentric roller sleeve 323. During operation, the position of the eccentric roller sleeve 323 can be flexibly adjusted according to the specific conditions of the material. When processing larger or harder materials, the rubbing plate assembly 330 oscillates eccentrically under the action of the eccentric roller assembly 320, thereby automatically increasing the distance between it and the crushing assembly 340, ensuring that the material smoothly enters the crushing zone and is initially crushed.

[0054] Dynamic breakage adjustment mechanism:

[0055] As the material is gradually broken into smaller pieces, the dynamic crushing adjustment mechanism in this embodiment comes into play. This mechanism relies on the design of the flexible strip 343, which connects the motion seat 341 and the positioning block 342, providing a certain degree of elastic adjustment during the crushing process. As the crushing process proceeds, the flexible strip 343 gradually reduces the gap between the washboard assembly 330 and the crushing assembly 340, ensuring further fine crushing of the smaller materials.

[0056] This adjustment not only maintains the continuity and stability of the crushing process, but also dynamically adjusts the crushing force according to the gradual changes in the material, ensuring the final crushing effect.

[0057] Overall crushing process and effect:

[0058] In this second embodiment, the washboard assembly 330 and the crushing assembly 340, through the coordinated operation of the intelligent control system and the eccentric roller group 320, can adapt to changes in different materials and achieve precise crushing operation. The material is initially crushed at a relatively large crushing gap. As the material size decreases, the crushing gap gradually shrinks, ultimately achieving complete crushing of the material.

[0059] This adjustment mechanism significantly improves the crushing efficiency and effectiveness of the equipment, ensures high adaptability when handling different materials, and reduces the need for equipment adjustment and maintenance due to changes in material properties.

[0060] Improved adaptability and durability:

[0061] Through the above design, this embodiment further improves the adaptability and durability of the vibratory conveyor. The combination of dynamic adjustment mechanism and eccentric oscillation design ensures that the equipment maintains high-efficiency crushing performance under long-term, high-load operation, while reducing mechanical fatigue and equipment wear, thus extending the service life of the equipment.

[0062] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
