Description

Technical Field

[0001] This utility model relates to the field of ore mining technology, specifically to a feeding device for fluorite mining. Background Technology

[0002] Fluorite, also known as fluorspar, is a common halide mineral, its main chemical component being calcium fluoride. Fluorite has a relatively low hardness, with a Mohs hardness of approximately 4 and a relative density of around 3.18. It exhibits fluorescence, emitting a beautiful glow under ultraviolet light or other excitation sources, hence its name. Fluorite is used as a flux in the metallurgical industry, as an important raw material in the chemical industry for the production of fluorides such as hydrofluoric acid, and in the optics field for manufacturing optical components. It is also commonly used in jewelry and scientific research. In underground mining, vertical shafts and inclined shafts are commonly used to enter the ore body, and then mining methods such as room-and-pillar mining and ore retention mining are used to extract the fluorite ore from the ore body. In open-pit mining, the topsoil and overburden are first stripped from the ore body, and then the ore is loosened by processes such as drilling and blasting. After preliminary crushing, the extracted ore is transported to a surface concentrator by hoisting equipment or transport vehicles, where it undergoes crushing, grinding, flotation and other beneficiation operations to improve the grade of fluorite concentrate, and finally obtain fluorite products that meet industrial requirements for use in different industrial fields.

[0003] A search revealed that Chinese Patent Publication No. CN221439367U discloses a feeding device for fluorite mining, including a conveying mechanism, an anti-falling mechanism, and a collecting mechanism. When the conveyor belt uses a chain plate, fluorite fragments fall through the gaps between the chain plates into an anti-falling trough fixed between the bottom ends of the support rods on both sides of the baffle. Since the inclination angle between the anti-falling trough and the conveyor belt is always consistent, the fragments in the anti-falling trough are driven by the inclination angle into the collection box, making it convenient for the personnel to collect the fragments. When the conveyor belt uses a belt conveyor, the fluorite fragments slide towards the lower inclination angle. During the sliding process, the fluorite fragments roll and bounce on the surface of the conveyor belt using the belt conveyor, and upon reaching the bottom, collide with the movable plate and fall through the gap between the movable plate and the conveyor belt into the top opening of the collection box. This allows miners to collect the fragments regardless of the type of conveyor belt used.

[0004] However, this device also has the following drawbacks:

[0005] Existing technologies typically use equipment such as forklifts to transfer fluorite ore to a conveyor belt for loading. During the loading process, fluorite ore may scatter outside the conveyor belt, and there may be large pieces of fluorite ore that are difficult to transport using a conveyor belt, which may also damage the conveyor belt. This device solves this problem. Utility Model Content

By setting up a feeding box, the fluorite ore can be concentrated at the discharge port, which facilitates the transfer of the fluorite ore to the conveyor belt and reduces the probability of the fluorite ore scattering outside the conveyor belt. By setting up a blocking bar and a crushing component, larger fluorite ore can be automatically filtered out and crushed, thereby preventing damage to the conveyor belt and solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A feeding device for fluorite mining includes a feeding box, one side of the bottom of the feeding box is set as a slope, and a discharge port is fixedly installed on the other side of the bottom of the feeding box. A conveyor belt is arranged directly below the discharge port.

[0009] It also includes a filter assembly, which includes multiple sets of blocking bars. The blocking bars are fixedly installed inside the upper part of the feeding box. The blocking bars are evenly distributed and one end of the blocking bar is higher than the other end.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-3 This utility model provides a technical solution:

[0025] A feeding device for fluorite mining includes a feeding box 1, one side of the bottom of the feeding box 1 is set as a slope, and a discharge port 2 is fixedly installed on the other side of the bottom of the feeding box 1. A conveyor belt 3 is arranged directly below the discharge port 2.

[0026] By setting up the feeding box 1, the fluorite ore can be concentrated and discharged uniformly from the discharge port 2, thereby moving the fluorite ore onto the conveyor belt 3 more accurately, preventing the fluorite ore from scattering outside the conveyor belt 3, improving work efficiency, and preventing pollution to the site environment.

[0027] It also includes a filter assembly, which includes multiple sets of blocking rods 4. The blocking rods 4 are fixedly installed inside the upper part of the feeding box 1. The blocking rods 4 are evenly distributed, and one end of the blocking rod 4 is higher than the other end.

[0028] By setting up multiple sets of blocking rods 4 in combination, larger fluorite ore can be filtered out, preventing blockage of the discharge port 2 and damage to the conveyor belt 3. Furthermore, by setting one end of the blocking rod 4 higher than the other end, the weight of the fluorite ore itself can be used to transfer it to the crushing box 8 for crushing, which improves work efficiency and reduces energy consumption.

[0029] It also includes a crushing assembly, which includes two sets of symmetrically arranged rotating rollers 5. Crushing teeth 6 are equidistantly installed on the surface of the rotating rollers 5. The crushing assembly also includes a crushing box 8, which is fixedly connected to the feeding box 1. The rotating rollers 5 are located inside the crushing box 8, and both ends of the rotating rollers 5 are rotatably connected to the crushing box 8. Two sets of motors 9 are fixedly installed on the outer wall of the crushing box 8. The output ends of the two sets of motors 9 are respectively connected to the two sets of rotating rollers 5. An inlet 10 is opened on one side of the upper part of the crushing box 8. The inlet 10 is located above the other side of the blocking rod 4 and is connected to the feeding box 1. An outlet 11 is opened on the lower side of one side of the crushing box 8 and is connected to the discharge port 2.

[0030] By setting two sets of motors 9, two sets of rotating rollers 5 can be driven to rotate in opposite directions, thereby crushing the fluorite ore with crushing teeth 6 and automatically guiding the crushed fluorite ore into the discharge port 2, which greatly improves the working efficiency. At the same time, it further prevents the large volume of fluorite ore from clogging the discharge port 2 and also prevents damage to the conveyor belt 3.

[0031] It also includes an adjustment assembly, which includes an adjustment plate 7. One side of the adjustment plate 7 is rotatably connected to the bottom side of the discharge port 2, and the other side of the adjustment plate 7 is rotatably connected to the telescopic end of the electric telescopic rod 12. One end of the electric telescopic rod 12 is rotatably connected to the outer wall of the discharge port 2 through a rotating seat 13.

[0032] By setting an electric telescopic rod 12, the adjusting plate 7 can be rotated, thereby opening and closing the discharge port 2. The opening angle of the discharge port 2 can also be controlled according to the needs of the operator, thereby controlling the discharge speed.

[0033] In practical use, the device is moved to a designated position, and fluorite ore is added to the feeding box 1 from above using external equipment. The fluorite ore slides down under its own weight. Smaller fluorite ore can slide down through the space between the blocking rods 4 into the discharge port 2, while larger fluorite ore cannot pass through the blocking rods 4 and slides on the lower side of the blocking rods 4, entering the crushing box 8 through the inlet 10. The two sets of motors 9 are started, and the output ends of the two sets of motors 9 drive the two sets of rotating rollers 5 to rotate in opposite directions, so that the crushing teeth 6 on the surface of the rotating rollers 5 crush the fluorite ore. The crushed fluorite ore slides down and falls into the discharge port 2 through the outlet 11. The extension ends of the two sets of electric telescopic rods 12 are controlled to extend, thereby pushing the adjusting plate 7 to open downwards. The fluorite ore moves to the conveyor belt 3 through the discharge port 2 for feeding.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
