Description

Technical Field

[0001] The invention relates to a modular anti-vibration feeding trolley, which is used in production processes such as mining and building material processing, and belongs to the technical field of material conveying equipment. Background Art

[0002] Many industrial processes, such as mining, building materials processing, and chemical production, require the transport of various materials from one location to another for processing. Feeder trolleys, a common type of material handling equipment, are widely used in these areas. Traditional feeder trolleys typically feature a monolithic design, lacking flexible functional expansion and adjustment capabilities. When production process changes require modifications to the feeder trolley's conveying speed or load capacity, the tightly interconnected components often require extensive disassembly and assembly of the entire equipment, which is time-consuming, labor-intensive, and costly. Furthermore, if a component fails during operation, it is difficult to quickly locate and replace the faulty part, resulting in significant downtime and disrupting production continuity. The lack of interchangeability between components further increases equipment maintenance costs and complicates spare parts management. During material conveying, the structural design of traditional feeder trolleys has limited ability to suppress vibration. Material vibration often negatively impacts the trolley's performance and stability, causing material spillage, increased wear, and reduced conveying accuracy, severely impacting its service life and subsequent maintenance costs. With the continuous expansion of industrial production scale and the improvement of production efficiency, higher requirements are placed on the conveying capacity, reliability and flexibility of the feeding trolley. Therefore, it is necessary to develop a new type of feeding trolley to solve these problems. Summary of the Invention

DETAILED DESCRIPTION

[0017] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] like Figures 1-13As shown, the present invention provides a modular anti-vibration feeding trolley, comprising a feeding hopper body 1, a feeding elbow 2, a trolley bracket 3, a connecting support 4, a trolley base 5, a front wheel assembly 6, a locating pin assembly 7, a rear wheel assembly 8, a channel steel 9, and fasteners. The trolley bracket 3 is fixed to the top of the trolley base 5 via four connecting supports 4, and the feeding hopper body 1 is fixed to the trolley bracket 3 via fasteners. The inlet end of the feeding elbow 2 is flange-connected to the outlet end of the feeding hopper body 1 via a flange 201 and fasteners, and its lower end is connected to the trolley bracket 3 via fasteners. The front and rear ends of the trolley base 5 are respectively provided with a front wheel assembly 6 and a rear wheel assembly 8, which are connected and fixed by fasteners. The trolley base 5 is welded with a locating pin assembly 7 around its periphery. The driving, feeding, and carrying systems of the feeding trolley are all independent modules, which facilitate transportation and installation, simplify maintenance and upgrades, and significantly improve the adaptability of the feeding trolley to meet diverse scenarios such as mining, chemical industry, and warehousing. The flexible interchangeability of the modules supports customization needs and reduces the user threshold.

[0019] The feeding hopper 1 comprises a hopper body 101, a discharge pipe 102, a bracket 103, a lifting lug 104, a return pipe 105, a wear-resistant liner 106, a bushing 107, and sealant. The hopper body 101 is a bucket-shaped structure with an inclined bottom. A circular hole is formed on one sidewall of the hopper body 101, connected to the return pipe 105, which is welded to the outside of the hopper body 101. A circular hole is formed on the other sidewall of the hopper body 101, connected to the discharge pipe 102. Brackets 103 are welded to both sides of the outer wall of the hopper body 101, and the lifting lug 104 is welded to the waist of the channel steel at the top of the bracket 103. This structure, through the synergistic effects of load-bearing, diversion, and protection, ensures the continuity and stability of material flow, while also reducing equipment loss and environmental impact through wear resistance and sealing, achieving efficient, low-cost, and safe material transportation.

[0020] The inner wall of the bucket body 101 is provided with a wear-resistant lining 106 through fasteners and sealant.

[0021] A bushing 107 is installed inside the discharge pipe 102 , and the bushing 107 is installed into the discharge pipe 102 from the inside of the bucket body 101 .

[0022] The feed elbow 2 is welded from multiple sections of elbow pipe. A flange 201 is welded to its upper end for connection to the feed hopper 1. A mounting base 202 is located at its lower midsection for attachment to the trolley support 3. A notch is provided at the end of the feed elbow 2 to facilitate material discharge. The overall structure offers flexible steering, reliable connection, stable support, and smooth material discharge. It can be flexibly matched to the feeder and trolley layouts. The modular interface and segmented structure simplify maintenance, reduce blockages, and improve material conveying efficiency.

[0023] The front wheel assembly 6 comprises a bearing assembly 1 601, a front wheel 602, a coupling 603, a drive motor 604, and a front axle 605. The front axle 605 is a stepped shaft with a keyway at one end. The front wheel 602 is mounted on the front axle 605 via a key. Bearing assemblies 1 601 are mounted on the front axle 605, located on either side of the front wheel 602. Two sets of front wheel assemblies 6 are connected to the output shafts on either side of the drive motor 604 via couplings 603. The front wheel assembly structure provides power to propel the vehicle. The keyed connection ensures synchronous transmission between the wheels and the axle. The double-sided bearings disperse the load, reducing friction and preventing axle deformation. The coupling ensures smooth power transmission.

[0024] The bearing assembly 1 601 and the drive motor 604 are assembled with the trolley base 5 through the bolt holes on the top.

[0025] The rear wheel assembly 8 comprises a second bearing assembly 801, a rear wheel 802, and a rear axle 803. The rear wheel 802 is mounted to the rear axle 803 via a key. The second bearing assembly 801 is mounted on the rear axle 803, located on either side of the rear wheel 802. The two rear wheel assemblies 8 are bolted together to the vehicle base 5 via bolt holes above the second bearing assembly 801. The rear wheel assembly's structural function is to provide passive load-bearing support, balancing the load with the front wheel to ensure smooth, slip-free transmission and operation, lower the vehicle's center of gravity, and enhance its anti-rollover capability.

[0026] The positioning pin assembly 7 includes a mounting bracket 701 and a positioning pin 702. The mounting bracket 701 is welded around the trolley base 5, and the positioning pin 702 is inserted into the mounting bracket 701. When the feeding trolley is working, the positioning pin 702 can be inserted into the foundation to fix the feeding trolley, thereby effectively improving the overall stability and vibration resistance of the trolley.

[0027] A channel steel 9 is welded obliquely between the trolley base 5 and the trolley bracket 3, which can be flexibly adjusted according to the on-site installation conditions, thereby increasing the strength and stability of the overall structure.

[0028] The present invention adopts a modular design as a whole, which can realize split packaging and transportation, reduce transportation costs, and shorten installation time. The front wheel assembly 6 of the trolley is the driving system, the feeding hopper body 1 is the feeding system, and the trolley bracket, connecting support and trolley base are the bearing system. Each system is an independent module, which can be flexibly assembled and replaced, thereby reducing maintenance costs and improving the versatility of the equipment. After the installation is completed, the motor 604 drives the trolley to move to the specified position, and then the positioning pin 702 is inserted into the foundation to complete the fixation. The method of engaging the positioning pin 702 with the foundation can effectively improve the overall stability and vibration resistance of the trolley; when the trolley needs to move as a whole, it is only necessary to pull out the positioning pin 702 and drive the motor to operate. The operation is simple and convenient. During the operation, the material enters from the square material port above the feeding hopper body, flows through the hopper body 101, the bushing 107, the feeding elbow 2, and enters the next level of production process; during this period, the material that needs secondary processing can be sent back to the return pipe 105 through other pipelines. As the material continues to wear, the wear-resistant liner 106 can be replaced in time according to the specific usage conditions. Replacing only the wear-resistant liner 106 is simple, has short downtime and low maintenance cost. If the wear is serious after long-term use, the feed hopper body 1 can be replaced as a whole to reasonably reduce the use cost.

[0029] This invention focuses on using a modular design concept to split the core functional components of the feeder trolley, such as the drive system, feeding system, and load-bearing system, into independent modules, enabling flexible assembly and replacement, effectively reducing maintenance costs and improving equipment versatility. At the same time, to address the common vibration problem during material transportation, an innovative vibration reduction design is used to achieve coupling with the foundation, reducing material spillage and equipment wear, and improving structural stability and service life. It is widely applicable to industrial scenarios with strict requirements for stable material transportation, such as mining, building material processing, and chemical production.
