Description

Technical Field

[0001] This invention relates to the field of bucket wheel excavator hopper technology, specifically an energy-saving and environmentally friendly bucket wheel excavator hopper. Background Technology

[0002] Bucket wheel excavators are used in large ports, power plants, coal mines, and other similar facilities. To ensure the structural balance of the large machine, these devices are typically designed with the bucket wheel and bucket wheel drive structure arranged separately on both sides of the suspension. The two are connected by the bucket wheel shaft passing through the top of the suspension. The bucket wheel excavator hopper is one of the key components of bucket wheel conveying machinery. It is mainly used to receive the bulk materials dug by the bucket wheel and guide them to subsequent conveying equipment to complete the continuous transfer of materials. It is the connecting hub between the bucket wheel and the subsequent conveying system. Its core functions include: receiving materials, centralized guidance, and buffering and homogenizing. The structure of the bucket wheel excavator hopper varies depending on the model and material characteristics, but a typical structure includes the following parts: hopper body, support and connection structure, auxiliary devices, etc.

[0003] Bucket wheel excavators are core equipment in bulk material storage yards for coal, ore, grain, and other materials. The hopper, as a key component, directly affects material handling efficiency, environmental performance, and equipment lifespan. Located at the material intake position at the end of the bucket wheel excavator boom, the hopper's main task is to accurately guide the bulk material conveyed by the excavator into downstream equipment, buffering and reducing the impact of falling material. As early as the mid-20th century, simple steel hoppers used ordinary carbon steel welded structures with no lining plates or only manganese steel plates for reinforcement. This simple design only met basic flow guidance functions, but when used with high-hardness materials, the hopper would wear through within 3-6 months. Furthermore, the open structure led to PM10 concentrations exceeding 100 mg / m³ at the operating site. 3This leads to dust accumulation, frequently causing blockages when handling sticky materials, requiring manual cleaning and posing significant safety hazards. The feed inlet of the bucket wheel excavator hopper connects to the conveyor belt of the bucket wheel excavator boom to receive materials. The guide plate uses a multi-stage inclined design to slow down the material's descent. The discharge outlet connects to downstream conveying equipment and can be equipped with a gate or vibrating feeder to control the flow. The support frame is mostly made of high-strength steel, a material resistant to impact and corrosion. Key accessories include wear-resistant liners, and the inner wall is covered with ceramic, high-chromium cast iron, or polyurethane linings to extend service life. The dust collection interface is used to connect to dry fog dust suppression or bag filter dust collection systems to reduce dust dispersion. Hoppers are classified by function as: stacking hoppers: used to store materials in the yard, with a simple structure and a focus on dust prevention; and retrieving hoppers: used when retrieving materials from the yard, requiring anti-clogging designs, such as adding grates to prevent large pieces of material; and hoppers classified by material... The quality of funnels can be categorized into steel funnels (the mainstream choice, low cost but requiring regular liner replacement) and composite material funnels (glass fiber reinforced plastic (FRP), corrosion-resistant but expensive). Based on cleaning methods, there are self-cleaning funnels (with vibration or air cannons for automatic unclogging) and fixed funnels (requiring manual intervention for cleaning). Current innovative designs for energy-saving and environmentally friendly funnels include structural optimization, intelligent control, and green technology. Features include: stepped flow guidance (multi-stage buffering reduces material kinetic energy, dust, and noise); lightweight design (using high-strength alloy steel, reducing weight by over 20%); sensor monitoring (real-time detection of material flow and humidity, automatically adjusting vibration frequency); energy efficiency management (linked with dust removal systems, entering sleep mode under low load); solar-assisted power supply (providing clean energy for the vibrator and dust removal system); and circulating water dust suppression (collecting rainwater for the dry fog system, reducing freshwater consumption). The future development trends of bucket wheel excavator hoppers can be categorized into several aspects: intelligentization (AI visual recognition of material blockage risks for predictive maintenance); material innovation (graphene-coated liners for 50% improved wear resistance); and zero-emission design (fully enclosed hopper with carbon capture technology). Bucket wheel excavator hoppers are core components for efficient bulk material transfer, and their design must balance wear resistance, blockage prevention, dust suppression, and energy saving. With the application of new materials and intelligent technologies, modern hoppers are developing towards longer lifespans, lower energy consumption, and zero pollution, becoming an important part of green mine and smart port construction.

[0004] A prior art material guiding device and bucket wheel excavator, application number 201310743034.5, provides a material guiding device for a bucket wheel excavator. The material guiding device includes a material guiding trough capable of absorbing ferrous impurities, and a chute for conveying material. One end of the chute has a feed port, and the other end has a discharge port. The material guiding device also includes a separation device for isolating impurities and a driving device. The separation device is located at the discharge port, and the driving device is located at the bottom of the separation device, capable of driving the separation device. The separation device includes a grid plate for isolating debris, positioned below the discharge port. It also includes a bracket fixed above the grid plate, with one end of the bracket abutting against the chute. The angle between the bracket and the guide chute is greater than zero degrees. First baffles, fixedly connected to the chute, are provided on both sides of the chute. The separation device includes second baffles, located on both sides of the bracket and fixedly connected to it. The bracket includes a first bracket and a second bracket, with one end of the first bracket abutting against the chute and the other end... The first support and the second support are fixedly connected to one end of the second support or are an integral part. The included angle between the first support and the second support is greater than zero degrees. One end of the second baffle is fixed to the side of the first support, and the other end is fixed to the same side of the second support as the first support. The second baffle is located on both sides of the included angle between the first support and the second support. On the other hand, the present invention also proposes a bucket wheel machine, including a bucket wheel, a boom, a boom conveyor belt and a material guiding device. The bucket wheel is located at one end of the boom, the material guiding device is located on the side of the bucket wheel, and the boom conveyor belt is located below the material guiding device. The material guiding device is any of the above-mentioned material guiding devices. Further, a support is fixed on the boom, one end of the drive device is located on the support, the connection point between the drive device and the support is a, and the other end of the drive device is located below the separation device. The drive device can drive the separation device to rotate around the connection point a. Compared with the prior art, the bucket wheel machine is equipped with the above-mentioned material guiding device, which can effectively protect the belt on the boom conveyor and reduce maintenance costs.

[0005] Traditional bucket wheel hopper designs involve material falling onto the bucket wheel shaft, then onto a cantilevered conveyor belt in two areas before and after the shaft. The material falling at an angle greater than or equal to 90° to the belt in the area in front of the shaft results in significant impact, spillage, and dust generation. The large speed difference leads to high energy consumption due to belt friction, excessive belt wear, and short belt life, resulting in high operating costs. Furthermore, existing bucket wheel hoppers lack a material guidance mechanism during discharge, causing material to easily accumulate at the connection between the bucket wheel shaft and the hopper sidewall. Material can also easily enter the rotating connection of the bucket wheel shaft, increasing resistance during rotation and further increasing energy consumption. Therefore, we propose an energy-saving and environmentally friendly bucket wheel hopper design. Summary of the Invention

The buffer regulating plate 11 buffers the falling material and finally lands on the material conveyor belt 32.

[0038] Working Principle: In operation, this energy-saving and environmentally friendly bucket wheel conveyor hopper operates as follows: the bucket wheel drive unit 12 drives the power shaft 2 to rotate, which in turn drives the bucket wheel rotating body 3 to rotate. The rotating body 3 then drives the bucket wheel hopper 4 to rotate. Simultaneously, the drive unit 12 drives the rotating shaft 29 to rotate, which in turn drives the material conveyor belt 32 to rotate. The bucket wheel hopper 4 picks up the material, and the material-blocking ring 14 is tightly attached to the inner wall of the rotating body 3. When the bucket wheel hopper 4 moves above the material-blocking ring 14, the material passes through the rotating body 3... The material is fed from the bucket wheel hopper 4. At this time, the receiving plate 8 in the insertion slot 5 receives the material. The material enters the bucket wheel hopper 6 under the action of the material guide plate 9. The speed control module adjusts the regulating motor 24. The regulating motor 24 drives the lead screw 23 to rotate. The lead screw 23 drives the push frame 22 to move. The push frame 22 drives the regulating frame 21 to rotate. The regulating frame 21 drives the buffer regulating plate 11 to rotate.
