Description

Technical Field

[0001] The present invention relates to the field of transportation, and in particular to a feeding device for fluorite ore mining. Background Art

[0002] Fluorite, also known as fluorspar, is the main source of fluorine in industry and is one of the more than 20 important non-metallic mineral raw materials in the world. Pure, colorless and transparent fluorite can be used as optical materials, and brightly colored fluorite can also be used as gemstones and raw materials for arts and crafts carving. During the process of mining fluorite ore, it is necessary to use a transportation device to feed the mined fluorite ore.

[0003] After retrieval, a Chinese patent application with the publication number of CN221439367U discloses a feeding device for fluorite ore mining, including a transmission mechanism, a falling prevention mechanism, and a collection mechanism. When the conveyor belt uses a chain plate line, the crushed slag of fluorite will fall through the gap between the chain plates to the anti-falling groove fixed between the bottom ends of the support rods on both sides of the baffle. Since the inclination angle of the anti-falling groove is always the same as that of the conveyor belt, the crushed slag in the anti-falling groove will be driven by the inclination angle into the chute collection box, which is convenient for the material taking personnel to recycle the crushed slag. When the conveyor belt uses a belt line, the fluorite crushed material will slide towards the direction of the lower point of the inclination angle. During the sliding process, the fluorite crushed material will roll and jump on the surface of the conveyor belt using the belt line, reach the bottom point, collide with the movable plate, and fall into the top opening of the collection box through the gap between the movable plate and the conveyor belt, which is convenient for mining personnel to collect the crushed slag regardless of the type of conveyor belt used.

[0004] When transporting and feeding fluorite ore, the mined fluorite is usually placed on the device and fed through the conveying mechanism. However, during the feeding process, some fluorite ores will stack together. At this time, the conveyor belt will be under greater pressure, which will damage the conveyor belt and further affect the feeding efficiency of fluorite. Summary of the Invention

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. By providing the conveying mechanism and the anti-piling mechanism, when feeding the mined fluorite, the fluorite is placed on the conveying mechanism, and the conveying mechanism is used to transport the fluorite during feeding. During this period, the anti-piling mechanism moves along with the movement of the conveying mechanism through the second transmission component. At this time, the rotating shaft drives the convex part to rotate through the cooperation between the two second belt pulleys and the second belt. The push rod drives the support plate to swing up and down reciprocally under the action of the convex part and the bushing. At this time, the limiting plate rotates synchronously with the support plate. When the limiting plate moves downward, the limiting plate levels the piled fluorite to increase the contact area between the fluorite and the conveying mechanism, prevent some fluorite ores from stacking together, resulting in a large pressure on the conveyor belt, thereby damaging the conveyor belt and affecting the feeding efficiency of the fluorite. As the limiting plate continues to move downward, at this time, the limiting plate divides the continuous fluorite, thus dividing a large amount of fluorite into multiple sections to reduce the pressure on the feeding mechanism, improve the feeding effect of the fluorite, and prevent a large amount of fluorite from acting on the feeding mechanism simultaneously due to being concentrated together, so that the feeding mechanism is damaged due to the increase in pressure, thereby affecting the feeding of the fluorite;

[0017] 2. When the fluorite falls on the feeding mechanism through the conveying mechanism in the present invention, due to the inclined setting of the feeding mechanism, the fluorite will slide downward. At this time, the fluorite will accumulate on one side of the isolation mechanism. Facing the accumulation of fluorite, at this time, some fluorite will fall off from the isolation mechanism, thus affecting the feeding of fluorite. At this time, as the fluorite slides, multiple fluorites will act on one side of the push plate, and the push plate will slide to one side under the action of the pressure of the fluorite. At this time, the push plate will extrude the airbag, and the gas inside the airbag will be transported to the inside of the notch through the air hole after being extruded. At this time, the air pressure inside the notch will increase with the input of gas, and the extension plate will extend upward under the action of the air pressure, so as to increase the isolation height of the partition plate and prevent the fluorite from spilling when sliding downward, thus affecting the feeding of fluorite.

[0035] In summary, by means of the above technical solutions of the present invention: when feeding the mined fluorite, the fluorite is placed on the conveying mechanism 4, and the conveying mechanism 4 transports and processes the feeding of the fluorite. During this period, the anti-piling mechanism 5 moves along with the movement of the conveying mechanism 4 through the second transmission component 23. At this time, the rotating shaft 31 drives the convex part 32 to rotate through the cooperation between the two second belt pulleys 35 and the second belt 36, and the push rod drives the support plate 27 to swing up and down reciprocally under the action of the convex part 32 and the bushing 33. At this time, the limiting plate 28 rotates synchronously with the support plate 27. When the limiting plate 28 moves downward, the limiting plate 28 levels the piled fluorite to increase the contact area between the fluorite and the conveying mechanism 4, preventing some fluorite ores from stacking together, resulting in a large pressure on the conveyor belt 11, thus damaging the conveyor belt 11 and affecting the feeding efficiency of the fluorite. As the limiting plate 28 continues to move downward, at this time, the limiting plate 28 divides the continuous fluorite, thus dividing a large amount of fluorite into multiple sections to reduce the pressure on the feeding mechanism 6, improve the feeding effect of the fluorite, and prevent a large amount of fluorite from acting on the feeding mechanism 6 simultaneously due to the concentration of the fluorite, thus damaging the feeding mechanism 6 due to the increase in pressure and affecting the feeding of the fluorite. When the fluorite falls on the feeding mechanism 6 through the conveying mechanism 4, since the feeding mechanism 6 is inclined, the fluorite will slide downward. At this time, the fluorite will accumulate on one side of the isolation mechanism 19. Facing the accumulation of the fluorite, at this time, some fluorite will fall off from the isolation mechanism 19, thus affecting the feeding of the fluorite. At this time, as the fluorite slides, multiple fluorites act on one side of the push plate 46, and the push plate 46 slides to one side under the action of the pressure of the fluorite. At this time, the push plate 46 squeezes the airbag 47, and the gas inside the airbag 47 is transported to the inside of the notch 42 through the air hole 48 after being squeezed. At this time, the air pressure inside the notch 42 increases with the input of the gas, and the extension plate 43 extends upward under the action of the air pressure to increase the isolation height of the partition plate 41, preventing the fluorite from spilling when sliding downward, thus affecting the feeding of the fluorite.

[0036] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto.
