Description

Technical Field

[0001] This utility model relates to the field of ore feeder technology, and in particular to a toothed heavy-duty ore feeder. Background Technology

[0002] In mining and mineral processing operations, feeders are key material conveying equipment, undertaking the important task of uniformly and continuously transporting raw ore or crushed ore to subsequent crushing and screening equipment. Their operational stability and conveying efficiency directly affect the capacity and energy consumption of the entire production line. However, existing feeders have many defects. First, they mostly adopt a direct-drive single-stage gear transmission method. When facing heavy ore with high hardness, large particle size or high density, this structure often leads to load concentration due to single-path transmission, excessive tooth surface contact stress, and problems such as gear wear and motor overload. Static load-bearing capacity is limited, making it difficult to adapt to high-intensity mineral processing scenarios. Meanwhile, direct drive has low efficiency and high energy loss. Moreover, the turntable is easily affected by uneven ore distribution during operation, resulting in radial runout and speed fluctuations, which leads to deviations in feed metering accuracy and fails to meet the material conveying stability requirements of high-precision mineral processing. Secondly, there is the problem of dust pollution. A large amount of dust, especially respirable dust, is generated during the crushing, falling and turntable conveying of ore. There is a lack of effective dust containment barriers, the dust diffusion coefficient is high, and the collection efficiency is generally less than 80%. This not only leads to excessive dust concentration in the working environment, violating occupational exposure limits, but also causes abrasive wear and reduced insulation performance due to dust adhering to the surfaces of transmission gears, motor windings and other components. The equipment maintenance cycle is shortened by more than 30%, and the maintenance cost is significantly increased. Utility Model Content

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: This utility model adopts a modular design.

It not only meets environmental protection requirements, but also effectively reduces the corrosion of equipment transmission parts and motors by dust, improves the cleanliness and reliability of equipment operation, and protects the occupational health of operators.

[0023] Working principle: Using this utility model, firstly, the dust collection mechanism 15 is set on the upper surface of the ore storage bin 7. The dust collection mechanism 15 consists of an ash storage box 1501, a fan 1502, and a dust collection pipe 1503. Then, the air curtain sealing mechanism 16 is fixed around the dust collection mechanism 15 on the upper surface of the annular fixing frame 6. The air curtain sealing mechanism 16 consists of an integrated ring 1601, a high-pressure air nozzle 1602, an air intake pipe 1603, an air pump 1604, and an air delivery pipe 1605. The planetary transmission mechanism 17 is fixedly connected to the bottom outer wall of the turntable 13 and is provided at the end of the rotating shaft 14. The planetary transmission mechanism 17 consists of a fixed chamber 1701, a rotating shaft 1702, an internal gear ring 1703, planetary gears 1704, a driven shaft 1705, a planet carrier 1706, an output shaft 1707, a sun gear 1708, a drive shaft 1709, and a rotating motor 1710. A support column 2 is fixedly connected to the bottom of the outer disk 1, a fixed bracket 3 is fixedly connected to the upper surface of the outer disk 1, and a stabilizing bracket 4 is fixedly connected to the bottom outer surface of the outer disk 1. An annular support frame 5 is fixedly connected to the fixed bracket 3 and the stabilizing bracket 4, and an annular fixed frame is fixedly connected to the annular support frame 5. 6. A storage bin 7 is fitted inside the annular fixed frame 6. A crushing box 8 is fixedly connected to the upper surface of the storage bin 7. An output motor 9 is installed on one outer wall of the crushing box 8. A shaft 10 is fitted to the output end of the output motor 9. A crushing roller 11 is fitted to the outer wall of the shaft 10. A lower hopper 12 is fixedly connected to one outer wall of the outer disc 1. In the transmission system, the rotating motor 1710 drives the turntable 13 to rotate through the planetary transmission mechanism 17. The sun gear 1708 receives the power from the motor and transmits it to the planetary carrier 1706 through the planetary gear 1704, driving the turntable 13 to rotate stably. The load-dispersing characteristics of multi-tooth meshing ensure the stable rotation speed of turntable 13 under heavy load. The ore is discharged from the outlet under the constraint of centrifugal force and outer disc 1. At the same time, the dust collection mechanism 15 and the air curtain sealing mechanism 16 work synchronously. The air source delivers inert gas to the integrated ring 1601 through the pipeline. The ring air curtain generator forms a sealed air hood to constrain the dust diffusion. The fan 1502 in the ash storage box 1501 generates negative pressure and sucks in the dust through the dust collection pipe 1503 to achieve efficient dust reduction. The whole process realizes the coordinated operation of ore crushing, precise feeding, stable transmission and dust control.
