Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to an adaptive feeding mechanism for ore materials. Background Art

[0002] Ore screening is a crucial step in the mining and mineral processing processes, aiming to separate ores or rocks by particle size for subsequent processing, extracting useful minerals, or waste treatment.

[0003] This process is crucial for improving the efficiency of mineral processing, reducing costs, and enhancing product quality.

[0004] Purpose of Screening

[0005] 1. Particle size classification: Divide the ore into different particle size levels to adopt the most suitable treatment methods for materials with different particle sizes.

[0006] 2. Impurity removal: Through screening, unwanted fine impurities or oversized waste rocks can be removed to improve the purity of the ore.

[0007] 3. Pretreatment preparation: Prepare for subsequent processing steps such as crushing, grinding, flotation, magnetic separation, and gravity separation.

[0008] 4. Recycling: In some cases, screening can recycle reusable materials, such as recovering usable sand and gravel in construction waste treatment.

[0009] It can be seen that screening can significantly improve the efficiency and economic benefits of subsequent processing.

[0010] However, existing ore screening operations usually use a single vibrating screen or drum screen for treatment. Although fine ore materials of a set size can be separated, large-sized ore materials remain in the equipment and need to be maintained regularly, resulting in relatively high operating costs and affecting operating efficiency. Summary of the Invention

[0011] The purpose of the utility model is to provide an adaptive feeding mechanism for ore materials with good applicability and a compact structure in view of the above problems existing in the prior art.

[0012] The purpose of the utility model can be achieved by the following technical solutions:

[0013] An adaptable feeding mechanism for mineral materials. The mineral material processing device includes a frame. It is characterized in that this adaptable feeding mechanism includes a hopper, a first feeding channel, and a second feeding channel. The interior of the hopper is a cavity, and the hopper is connected to the upper part of the frame. The upper part and the end of the hopper are open. The bottom of the hopper is an inclined discharging surface. There is a feeding hole on the discharging surface near the end opening of the hopper. The first feeding channel and the second feeding channel are fixedly connected in the frame and arranged front and back along the moving direction of the mineral materials. The upper end of the first feeding channel is communicated with the feeding hole. The upper end of the second feeding channel is communicated with the opening at the end of the hopper. There is also a conveyor belt for transporting the mineral materials at the bottom of the frame. There is a crushing mechanism for crushing the mineral materials at the second feeding channel.

[0014] This adaptable feeding mechanism for mineral materials creatively sets two feeding channels on the frame: the first feeding channel and the second feeding channel.

[0015] The end of the hopper is one of the discharging parts, and the feeding hole at the bottom of the hopper is the other discharging part.

[0016] The size of the feeding hole is relatively small. Therefore, most of the fine mineral materials are output at the feeding hole. Since the first feeding channel is communicated with this place, the fine mineral materials are transported to the conveyor belt by the independent first feeding channel.

[0017] The mineral materials with relatively large sizes cannot enter the feeding hole. Therefore, the large-sized mineral materials are output from the end of the hopper. Since the second feeding channel is communicated with the end of the hopper, the large-sized mineral materials are transported to the conveyor belt by the independent second feeding channel.

[0018] Since there is a crushing mechanism in the second feeding channel, the large-sized mineral materials can be stably crushed under the action of the crushing mechanism, and finally the fine mineral materials are output from the second feeding channel.

[0019] That is to say, the mineral materials entering the conveyor belt are all fine mineral materials. Under the action of the conveyor belt, the above-mentioned fine mineral materials are stably transported to the next processing procedure.

[0020] In the above adaptable feeding mechanism for mineral materials, the number of the feeding holes is several.

[0021] The setting of multiple feeding holes can ensure the output efficiency of the fine mineral materials.

[0022] In the above adaptable feeding mechanism for mineral materials, the feeding holes are strip-shaped. A plurality of feeding holes arranged parallel to the width direction of the hopper form a feeding unit. The number of the feeding units is several. The several feeding units are arranged adjacent to each other front and back along the conveying direction of the mineral materials. The upper end of the first feeding channel is communicated with all the feeding units.

[0023] The setting of multiple feeding units can further improve the output efficiency of the fine mineral materials.

[0024] In the above-mentioned adaptable blanking mechanism for ore materials, the first blanking channel includes a first pipe body, a second pipe body, and a third pipe body. The second pipe body is located between the first pipe body and the third pipe body and the three are connected. The first pipe body and the third pipe body are both vertically arranged, the second pipe body is inclined, and the third pipe body is adjacent to the second blanking channel.

[0025] Since the blanking unit is relatively far from the outlet at the end of the hopper, such a structure can make the third pipe body as adjacent as possible to the second blanking channel.

[0026] That is to say, both the first blanking channel and the second blanking channel convey the fine ore materials to the set position of the conveyor belt, thereby improving the conveying stability.

[0027] In the above-mentioned adaptable blanking mechanism for ore materials, a first positioning rod arranged horizontally is provided inside the frame. The first positioning rod is in surface contact with the side of the pipe body and the two are fixedly connected by fasteners.

[0028] Such a structure can stably fix the upper part of the first blanking channel inside the frame.

[0029] In the above-mentioned adaptable blanking mechanism for ore materials, a second positioning rod arranged horizontally is also provided inside the frame. The second positioning rod is fixedly connected with the second pipe body through a bracket.

[0030] Such a structure can stably fix the middle part of the first blanking channel inside the frame.

[0031] In the above-mentioned adaptable blanking mechanism for ore materials, the upper part of the bracket is in surface contact with the inclined side surface of the outside of the second pipe body and the two are fixedly connected by fasteners. The lower part of the bracket is in surface contact with the upper part of the second positioning rod and the two are fixedly connected by fasteners.

[0032] Such a structure can stably connect the bracket and the second pipe body together.

[0033] In the above-mentioned adaptable blanking mechanism for ore materials, the second blanking channel includes a first baffle, a second baffle, a first crushing plate, and a second crushing plate. The first baffle and the second baffle are fixedly connected in parallel inside the frame. The two sides of the first crushing plate are respectively fixedly connected to the edges of the first baffle and the second baffle. The upper end of the second crushing plate is hinged to the other edge of the first baffle and the second baffle, and the first crushing plate and the second crushing plate are arranged opposite to each other.

[0034] In the above-mentioned adaptable blanking mechanism for ore materials, a motor is fixedly connected to the frame. The upper end of the second crushing plate is hinged to the frame through a pin shaft. A flywheel disc is movably connected to the upper end of the second crushing plate. The output end of the motor is connected to the flywheel disc.

[0035] During the continuous rotation of the flywheel disc driven by the motor, there is an appropriate frictional resistance between the second crushing plate and the flywheel disc. Therefore, the second crushing plate can swing around its upper hinge point.

[0036] In the above-mentioned adaptable blanking mechanism for ore materials, it further includes a connecting rod and a spring. There is a positioning plate inside the above-mentioned frame. The above-mentioned connecting rod is passed through the positioning plate. The inner end of the connecting rod is hinged at the lower end of the second crushing plate. The above-mentioned spring is sleeved on the connecting rod, and both ends of the spring respectively press against the positioning plate and the outer end of the connecting rod. Under the elastic force of the spring, the second crushing plate has a tendency to move away from the first crushing plate.

[0037] Since there are a connecting rod and a spring between the lower end of the second crushing plate and the positioning plate of the frame, the second crushing plate is always subjected to the elastic force of the spring. Therefore, under the action of the spring, the second crushing plate can be ensured to reset, and at the same time, excessive swinging of the second crushing plate can be avoided.

[0038] Compared with the prior art, in the adaptable blanking mechanism for the ore materials of the present invention, since small-sized ore materials can stably enter the conveyor belt through the first blanking channel, after the large-sized ore materials enter the second blanking channel, the large-sized ore materials can be crushed. Finally, the second blanking channel still inputs small-sized ore materials to the conveyor belt, and the conveyor belt then conveys the above-mentioned small-sized ore materials to the next processing step. Its operation efficiency is high and the conveying is stable. Whether it is small-sized ore materials or large-sized ore materials, after being conveyed by this blanking mechanism, stable small-sized ore materials can be obtained at the conveyor belt, and its stability and applicability are relatively high.

[0039] At the same time, the first blanking channel and the second blanking channel are arranged adjacent to each other in a concentrated manner, and the structure of the whole mechanism is relatively compact, having high practical value. Brief Description of the Drawings

[0046] As Figure 1 shown, the ore material processing device includes a frame 1.

[0047] As Figure 1 and Figure 2 shown, the adaptable blanking mechanism for the present ore material includes a hopper 2, a first blanking channel 3 and a second blanking channel 4. The interior of the hopper 2 is a cavity, and the hopper 2 is connected to the upper part of the frame 1. The upper part and the end of the hopper 2 are open. The bottom of the hopper 2 is an inclined discharging surface 2a. A blanking hole 2a1 is provided on the discharging surface 2a near the end opening of the hopper 2.

The upper end of the first blanking channel 3 is communicated with the blanking hole 2a1. The upper end of the second blanking channel 4 is communicated with the opening at the end of the hopper 2. A conveyor belt 13 for transporting the ore material is further provided at the bottom of the frame 1. A crushing mechanism for crushing the ore material is provided at the second blanking channel 4.

[0048] The number of the blanking holes 2a1 is several.

[0049] The blanking holes 2a1 are in strip shape. A plurality of blanking holes 2a1 arranged parallel to the width direction of the hopper 2 form a blanking unit. The number of the blanking units is several. A plurality of blanking units are arranged adjacent to each other front and back along the conveying direction of the ore material. The upper end of the first blanking channel 3 is communicated with all the blanking units.

[0050] The first blanking channel includes a first pipe body 3a, a second pipe body 3b, and a third pipe body 3c. The second pipe body 3b is located between the first pipe body 3a and the third pipe body 3c and the three are connected. The first pipe body 3a and the third pipe body 3c are both vertically arranged, the second pipe body 3b is inclined, and the third pipe body 3c is adjacent to the second blanking channel 4.

[0051] There is a horizontally arranged first positioning rod 5 inside the frame 1. The first positioning rod 5 is in surface contact with the side of the first pipe body 3a and the two are fixedly connected by fasteners.

[0052] There is also a horizontally arranged second positioning rod 6 inside the frame 1. The second positioning rod 6 is fixedly connected to the second pipe body 3b by a bracket 7.

[0053] The upper part of the bracket 7 is in surface contact with the inclined side of the outside of the second pipe body 3b and the two are fixedly connected by fasteners. The lower part of the bracket 7 is in surface contact with the upper part of the second positioning rod 6 and the two are fixedly connected by fasteners.

[0054] The second blanking channel 4 includes a first baffle 4a, a second baffle 4b, a first crushing plate 4c, and a second crushing plate 4d. The first baffle 4a and the second baffle 4b are fixedly connected in parallel inside the frame 1. The two sides of the first crushing plate 4c are respectively fixedly connected to the edges of the first baffle 4a and the second baffle 4b. The upper end of the second crushing plate 4d is hinged to the other edge of the first baffle 4a and the second baffle 4b, and the first crushing plate 4c and the second crushing plate 4d are arranged opposite to each other.

[0055] A motor 8 is fixedly connected to the frame 1. The upper end of the second crushing plate 4d is hinged to the frame 1 through a pin shaft. A flywheel disc 9 is movably connected to the upper end of the second crushing plate 4d. The output end of the motor 8 is connected to the flywheel disc 9.

[0056] It further includes a connecting rod 10 and a spring 11. There is a positioning plate 12 inside the frame 1. The connecting rod 10 passes through the positioning plate 12. The inner end of the connecting rod 10 is hinged to the lower end of the second crushing plate 4d. The spring 11 is sleeved on the connecting rod 10 and the two ends of the spring 11 respectively press against the positioning plate 12 and the outer end of the connecting rod 10. Under the elastic force of the spring 11, the second crushing plate 4d has a tendency to move away from the first crushing plate 4c.

[0057] The inventive adaptable blanking mechanism for ore materials creatively provides two blanking channels on the frame: the first blanking channel and the second blanking channel.

[0058] One end of the hopper is one of the discharging parts, and the blanking hole at the bottom of the hopper is the other discharging part.

[0059] The size of the blanking hole is relatively small. Therefore, most of the fine ore materials are discharged at the blanking hole. Since the first blanking channel is connected to this place, the fine ore materials are conveyed to the conveyor belt by the independent first blanking channel.

[0060] The ore materials with relatively large sizes cannot enter the blanking hole. Therefore, the large-sized ore materials are output from the end of the hopper. Since the second blanking channel is connected to the hopper end, the large-sized ore materials are conveyed to the conveyor belt through the independent second blanking channel.

[0061] Since there is a crushing mechanism in the second blanking channel, the large-sized ore materials can be stably crushed under the action of the crushing mechanism and finally the fine ore materials are output from the second blanking channel.

[0062] That is to say, the ore materials entering the conveyor belt are all fine ore materials. Under the action of the conveyor belt, the above-mentioned fine ore materials are stably conveyed to the next processing step.

[0063] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0064] Those of ordinary skill in the art of this technology should recognize that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. As long as appropriate changes and variations made to the above embodiments are within the scope of the substantial spirit of the present invention, they fall within the scope of protection required by the present invention.
