Description

Technical Field

[0001] The utility model relates to iron ore mining and crushing equipment, belonging to the technical field of crushing equipment. Background Art

[0002] Iron ore is any ore containing economically viable iron. It is a key raw material for steel production. Natural ore (iron ore) is gradually separated from the iron through processes such as crushing, grinding, magnetic separation, flotation, and gravity separation. Iron ore is a mineral aggregate containing elemental iron or iron compounds that can be economically utilized.

[0003] For example, CN220405765U discloses an iron ore mining and crushing device. The dust generated during the discharge of the crushed iron ore is filtered by a suction filter frame. This not only protects the health of workers and the production environment and improves production efficiency, but also allows the dust to be recycled and reused, achieving resource reuse. However, the larger filtered raw materials need to be manually collected and poured into the shell for crushing, which is inconvenient and affects work efficiency. In addition, the crushed raw materials will be contaminated with a certain amount of dust, which cannot be completely absorbed by the fan. When the raw materials are transferred for use, a certain amount of dust will still be generated, affecting the surrounding air environment. Utility Model Content

[0004] The purpose of the present utility model is to provide an iron ore mining and crushing equipment, which provides a conveying box and a conveying auger. After the filter plate filters out the larger raw materials, the unqualified raw materials will enter the conveying box along the filter plate and the guide box. The conveying auger can guide the raw materials again onto the crushing roller for crushing, thereby reducing the labor intensity of the workers and improving work efficiency. In addition, by providing a water inlet pipe and a water collecting plate on the discharge pipe, the water collecting plate can spray water to the raw materials entering the discharge pipe to remove and wet the dust on the raw materials, thereby preventing the raw materials from generating dust when they are taken out for reprocessing and reducing pollution to the surrounding environment, so as to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] An iron ore mining and crushing equipment includes a protective shell, a feed pipe is provided above the protective shell, a crushing roller is provided inside the protective shell below the feed pipe, a filter plate 1 is provided below the crushing roller, a material guide box is provided at one end of the filter plate 1, one end of the material guide box is connected to a conveying box, a discharge pipe is provided at the bottom of the protective shell, a water inlet pipe is provided on one side above the discharge pipe, the bottom of the discharge pipe is connected to a distribution box, a filter plate 2 is provided inside the distribution box, and a discharge port is provided on one side of the distribution box.

[0007] Furthermore, guide plates are provided on both sides above the crushing roller, and the guide plates are connected to the inner wall of the protective shell.

[0009] Furthermore, the angle between the top of the conveying box and the protective shell is 30 degrees to 40 degrees, and the height of the top of the conveying auger is greater than the height of the guide plate.

[0010] Furthermore, a vibration motor is provided under the filter plate 1 and the filter plate 2, and the number of the vibration motors under the filter plate 1 and the filter plate 2 is 2-4.

[0025] Specifically, guide plates 12 are provided on both sides above the crushing roller 3, and the guide plates 12 are connected to the inner wall of the protective shell 1. The filter plate 4 is inclined toward the side of the guide box 5, and one end of the guide box 5 is inclined toward the conveying box 6. The top of the conveying box 6 is connected to the protective shell 1, and a conveying auger 13 is provided inside the conveying box 6. The bottom of the conveying auger 13 is connected to the output end of the servo motor 14. The angle between the top of the conveying box 6 and the protective shell 1 is 30 degrees to 40 degrees. The height of the top of the conveying auger 13 is greater than the height of the guide plates 12. The guide plates 12 can guide the raw materials to the crushing roller 3, so that the raw materials can be crushed conveniently. The conveying box 6 and the conveying auger 13 can filter the raw materials with unqualified volume filtered by the filter plate 4 and transport them to the top of the crushing roller 3 for crushing again, thereby reducing the operation of workers, reducing the labor intensity of workers, and improving work efficiency.

[0026] Specifically, a vibration motor 15 is provided under the filter plate 1 4 and the filter plate 2 10. The number of the vibration motors 15 under the filter plate 1 4 and the filter plate 2 10 is 2-4. The vibration motor 15 can vibrate the filter plate 1 4 and the filter plate 2 10 to facilitate guiding the material downward and prevent the material from accumulating or clogging above the filter plate 1 4 and the filter plate 2 10.

[0027] Example 2: Please refer to Figure 3 The difference between this embodiment and embodiment 1 is that: a booster pump 16 is connected to the water inlet pipe 8, one end of the water inlet pipe 8 is connected to a water collecting plate 17, a number of high-pressure nozzles 18 are provided under the water collecting plate 17, a drain pipe 19 is provided on the lower side of the inside of the distribution box 9, one end of the filter plate 10 is inclined toward the side of the discharge port 11, the water collecting plate 17 and the high-pressure nozzle 18 can spray water to the raw materials entering the discharge pipe 7, remove and wet the dust on the raw materials, thereby preventing the raw materials from generating dust when they are taken out for reprocessing, and reducing pollution to the surrounding environment.

[0028] The working principle of the utility model is as follows: when in use, the raw materials are first put into the feed pipe 2, and the crushing roller 3 can crush the raw materials when it rotates. When the crushed raw materials fall on the filter plate 4, the raw materials with qualified volume can pass through the filter plate 4 and fall downward, and the raw materials with unqualified volume will move along the filter plate 4 to the guide box 5 and enter the conveying box 6. When the servo motor 15 is running, it can drive the conveying auger 13 to rotate. When the conveying auger 13 rotates, it can drive the raw materials to move upward and enter the protective shell 1 again for crushing. When the raw materials enter the discharge pipe 7, the water inlet pipe 8 and the booster pump 16 will introduce water into the water collecting plate 17, so that the water collecting plate 17 can spray high-pressure water to the raw materials through the high-pressure nozzle 18 to flush and wet the raw materials. Finally, the raw materials enter the distribution box 9 and fall on the filter plate 2 10. The filter plate 2 10 will vibrate under the drive of the vibration motor 15 to guide the raw materials to the discharge port 11.
