Description

Technical Field

[0001] This utility model 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 Technology

[0002] In many industrial production processes, such as mining, building materials processing, and chemical production, various materials need to be transported from one location to another for processing. Feeding trolleys, as a common material conveying device, are widely used in these fields. Traditional feeding trolleys typically employ an integrated design, lacking flexible functional expansion and adjustment capabilities. When production processes change, requiring modifications to the feeding trolley's conveying speed and load-bearing capacity, the tightly connected components often necessitate large-scale disassembly and reassembly of the entire equipment, which is time-consuming, labor-intensive, and costly. Moreover, if a component malfunctions during operation, it is difficult to quickly locate and replace the faulty part, leading to prolonged downtime and impacting production continuity. The lack of interchangeability between different components further increases equipment maintenance costs and the difficulty of spare parts management. During material conveying, the traditional feeding trolley's structural design has limited vibration suppression capabilities. Material vibration often adversely affects the feeding trolley's performance and stability, such as causing material spillage, accelerated 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. Utility Model Content

Detailed Implementation

[0029] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1-13 As shown, this utility model provides a modular anti-vibration feeding trolley, including a feeding hopper 1, a feeding bend 2, a trolley bracket 3, connecting supports 4, a trolley base 5, a front wheel assembly 6, a positioning pin assembly 7, a rear wheel assembly 8, a channel steel 9, and fasteners. The trolley bracket 3 is fixed above the trolley base 5 by four connecting supports 4, and the feeding hopper 1 is fixed to the trolley bracket 3 by fasteners. The inlet end of the feeding bend 2 is connected to the outlet flange of the feeding hopper 1 by a flange 201 and fasteners, and its lower end is connected to the trolley bracket 3 by fasteners. The front wheel assembly 6 and the rear wheel assembly 8 are respectively provided at the front and rear ends of the trolley base 5 and are connected and fixed by fasteners. Positioning pin assemblies 7 are welded around the trolley base 5. The driving, feeding, and load-bearing systems of the feeding trolley are all independent modules, which facilitates transportation and installation and simplifies maintenance and upgrades. It significantly improves the adaptability of the feeding trolley, meets diverse scenarios such as mining, chemical, and warehousing, and the flexible interchangeability of the modules supports customized needs, lowering the user threshold.

[0031] The feeding hopper 1 includes a hopper body 101, a discharge pipe 102, a support 103, a lifting lug 104, a return pipe 105, a wear-resistant liner 106, a bushing 107, and sealant. The hopper body 101 has a hopper-shaped structure with an inclined bottom. A circular hole is opened on one side wall of the hopper body 101, connecting to the return pipe 105, which is welded to the outside of the hopper body 101. A circular hole is opened on the other side wall of the hopper body 101, connecting to the discharge pipe 102. Supports 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 support 103. This structure, through the synergistic effect of load-bearing, flow guidance, and protection, ensures the continuity and stability of material flow, while reducing equipment wear and environmental impact through wear resistance and sealing, achieving efficient, low-consumption, and safe material conveying.

[0032] The inner wall of the bucket body 101 is provided with a wear-resistant liner 106 by fasteners and sealant.

[0033] The inner side of the discharge pipe 102 is equipped with a bushing 107, which is inserted into the discharge pipe 102 from the inside of the bucket body 101.

[0034] The feeding bend 2 is made of multiple sections of welded pipes. A flange 201 is welded to its upper end for connection to the feeding hopper 1, and a mounting base 202 is located at the lower middle section for fixing to the trolley bracket 3. The end of the feeding bend 2 has a notch for easy material discharge. The overall structure is flexible in steering, reliable in connection, stable in support, and smooth in material discharge. It can flexibly match the layout of the feeding hopper and trolley. The modular interface combined with the segmented structure reduces maintenance difficulty, minimizes blockages, and improves material conveying efficiency.

[0035] The front wheel assembly 6 includes a bearing assembly 601, a front wheel 602, a coupling 603, a drive motor 604, and a front axle 605. The front axle 605 has a stepped shaft structure with a keyway at one end. The front wheel 602 is mounted on the front axle 605 via a key. The bearing assembly 601 is mounted on the front axle 605 and distributed on both sides of the front wheel 602. The two sets of front wheel assemblies 6 are connected to the output shafts on both sides of the drive motor 604 via the coupling 603. The front wheel assembly structure provides power to drive the vehicle. The key connection ensures synchronous transmission between the wheel and the axle; the double-sided bearings distribute the load, reducing friction during driving and preventing axle deformation; the coupling connection ensures smooth power transmission.

[0036] The bearing assembly 601 and the drive motor 604 are joined together with the trolley base 5 through the bolt holes on the top.

[0037] The rear wheel assembly 8 includes a second bearing assembly 801, a rear wheel 802, and a rear axle 803. The rear wheel 802 is mounted on the rear axle 803 via a key. The second bearing assembly 801 is mounted on the rear axle 803 and distributed on both sides of the rear wheel 802. The two sets of rear wheel assemblies 8 are joined together with the trolley base 5 through bolt holes on the upper part of the second bearing assembly 801. The structural function of the rear wheel assembly is passive load-bearing support, working with the front wheels to balance the load, ensuring smooth transmission and follow-through without slippage, stable operation, lowering the center of gravity of the vehicle, and improving anti-rollover capability.

[0038] The positioning pin assembly 7 includes a mounting bracket 701 and a positioning pin 702. The mounting bracket 701 is welded around the base 5 of the trolley, 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, effectively improving the overall stability and vibration resistance of the trolley.

[0039] A channel steel 9 is welded at an incline between the trolley base 5 and the trolley bracket 3, which can be flexibly adjusted according to the on-site installation conditions, increasing the strength and stability of the overall structure.

[0040] This utility model adopts a modular design, enabling separate packaging and transportation, reducing transportation costs and shortening installation time. The front wheel assembly 6 of the trolley is the drive system, the feeding hopper 1 is the feeding system, and the trolley bracket, connecting support, and trolley base are the load-bearing system. Each system is an independent module, allowing for flexible assembly and replacement, thereby reducing maintenance costs and improving equipment versatility. After installation, the motor 604 drives the trolley to the designated position, and then the positioning pin 702 is inserted into the foundation to complete the fixation. The method of using the positioning pin 702 to engage with the foundation can effectively improve the overall stability and vibration resistance of the trolley. When the trolley needs to be moved as a whole, simply pull out the positioning pin 702 and drive the motor to run, making the operation simple and convenient. During operation, the material enters from the square material inlet above the feeding hopper, flows through the hopper 101, bushing 107, and feeding bend 2, and enters the next stage of production process; materials requiring secondary processing can be sent back to the return pipe 105 through other pipelines. As the material continues to wear down, the wear-resistant liner 106 can be replaced in a timely manner according to the specific usage conditions. Replacing only the wear-resistant liner 106 is simple, requires minimal downtime, and has low maintenance costs. If the wear becomes severe after long-term use, the entire feed hopper body 1 can be replaced, reasonably reducing operating costs.

[0041] This utility model focuses on using a modular design concept to break down the core functional components of the feeding 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. Simultaneously, addressing the common vibration problem during material conveying, an innovative vibration reduction design is adopted to achieve coupling with the foundation, reducing material spillage and equipment wear, improving structural stability and service life. It is widely applicable to industrial scenarios with stringent requirements for stable material conveying, such as mining, building material processing, and chemical production.
