Description

Technical Field

[0001] This utility model relates to the field of coal mining technology, specifically to a thin coal seam backfilling mining device. Background Technology

[0002] With the continuous growth of global energy demand, coal, as one of the important fossil energy sources, has seen its mining efficiency and safety become a focus of attention in the mining industry. Thin coal seams, as an important component of coal resources, have always presented a challenge and a hot topic in mining engineering. As a major coal-producing base in the world, my country has achieved significant breakthroughs in fully mechanized and longwall mining of thick coal seams, placing it in a leading position internationally. However, fully mechanized mining of thin coal seams remains a relatively weak link. After coal mining, sorting is required, and some waste material needs to be used for backfilling, necessitating a thin coal seam backfilling mining device.

[0003] Chinese patent CN217069546U discloses a device for thin coal seam mining in open-pit coal mines, including a drum with multiple sets of screen holes. One end of the drum is provided with a sealing plate, and a fixing part is provided on one side wall of the sealing plate. The fixing part is provided with a first belt groove. A motor is provided below the drum, and a turntable is provided on the motor. The turntable is provided with a second belt groove. A fixing ring is provided on the outer wall of the drum, and a support leg is provided at the bottom of the fixing ring. The first belt groove and the second belt groove are connected by a belt.

[0004] In existing thin coal seam filling mining devices, during the screening and filtration of raw coal, the large number of screen holes on the outer wall of the drum, driven by a motor, causes coal to be thrown out of the drum at high speeds, affecting the collection effect. At the same time, the lack of a stirring mechanism inside the drum results in a significant time requirement for screening the raw coal, impacting work efficiency. Furthermore, the coal is not spread out in time within the collection mechanism during collection, leading to a poor collection effect. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a thin coal seam backfilling mining device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0023] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0024] like Figure 1-3 As shown, this utility model provides a thin coal seam filling mining device, including a protective shell 3 and a fixed base 701. The protective shell 3 is equipped with a stirring assembly, which includes a connecting shaft 403 and a stirring plate 404. The outer wall of the connecting shaft 403 is equipped with a protective frame 6. The inner wall of the protective frame 6 is fixedly installed with a filter cylinder 5 by several fixing plates 601. One end of the filter cylinder 5 is threadedly connected to a cylinder cover 501. The stirring assembly also includes a motor 401 and a rotating shaft 402. The motor 401 is fixedly installed inside the protective shell 3. The rotating shaft 402 is fixedly connected to the output end of the motor 401 and rotatably connected to the protective frame 6. The connecting shaft 403 is fixedly connected to the rotating shaft 402 and rotatably connected to the filter cylinder 5. The stirring plate 404 is fixedly sleeved on the connecting shaft 403. Several fixing plates 601 are fixedly installed on the inner wall of the protective frame 6 and fixedly connected to the filter cylinder 5. Several support frames 602 are fixedly installed on the outer wall of the protective frame 6.

[0025] The staff first rotates and removes the cylinder cover 501, then pours the coal to be filtered into the filter cylinder 5, and then reinstalls the cylinder cover 501. Then, the motor 401 is started. When the output end of the motor 401 rotates, it drives the rotating shaft 402 to rotate. After the rotating shaft 402 rotates, it drives the connecting shaft 403 and the stirring plate 404 to rotate. After the stirring plate 404 rotates, it stirs the coal in the filter cylinder 5, which effectively improves the screening efficiency of the coal. At the same time, the coal discharged from the filter cylinder 5 can be guided by the inside of the protective frame 6, reducing the probability of the coal splashing when discharged, thereby increasing the amount and collection efficiency of the coal falling into the collection frame 8.

[0026] like Figure 4-5 As shown, in one embodiment, a rotating assembly 7 is provided at one end of the fixed base 701. The rotating assembly 7 includes a second rotating shaft 703 and a support frame 705. A collection frame 8 is provided inside the support frame 705, and a slot 7050 is opened at one end. An L-shaped plate 706 is provided inside the slot 7050. The rotating assembly 7 also includes a second motor 702, a second rotating shaft 703, and a connecting frame 704. The second motor 702 is fixedly installed at one end of the fixed base 701. One end of the second rotating shaft 703 is fixedly connected to the output end of the second motor 702. The connecting frame 704 is fixedly sleeved on the outer wall of the second rotating shaft 703. The support frame 705 is fixedly connected to the connecting frame 704. The L-shaped plate 706 is slidably engaged with the slot 7050. The collection frame 8 is slidably engaged with the inner wall of the support frame 705.

[0027] After collecting a portion of coal in the collection frame 8, start motor 702. The output end of motor 702 will rotate slightly back and forth. When the output end of motor 702 rotates, it drives shaft 703 to rotate. When shaft 703 rotates, it drives connecting frame 704 and bearing frame 705 to rotate. This causes bearing frame 705 to drive collection frame 8 to rotate slightly back and forth, so that the coal in collection frame 8 can be spread flat in collection frame 8 while rotating, further improving the collection effect. After the coal screening is completed, the coal remaining in filter cylinder 5 is taken out and then used for filling material. Then, L-shaped plate 706 and collection frame 8 are taken out to complete the screening work.

[0028] Motor 2 702 is a forward and reverse motor. Forward and reverse motors are existing technology and will not be explained here.

[0029] like Figure 1 As shown, in one embodiment, a support arm 2 is fixedly installed at the bottom of the protective shell 3, a bearing plate 1 is fixedly installed at the bottom of the support arm 2, and a plurality of threaded holes 101 are provided at the top of the bearing plate 1.

[0030] Workers can install reinforcement workpieces through threaded hole 101 to improve equipment stability.

[0031] The working principle of this thin coal seam backfilling mining device will be explained in detail below:

[0032] The staff first rotates and removes the cylinder cover 501, then pours the coal to be filtered into the filter cylinder 5, and then reinstalls the cylinder cover 501. Then, the motor 401 is started. When the output end of the motor 401 rotates, it drives the rotating shaft 402 to rotate. After the rotating shaft 402 rotates, it drives the connecting shaft 403 and the stirring plate 404 to rotate. After the stirring plate 404 rotates, it stirs the coal in the filter cylinder 5, which effectively improves the screening efficiency of the coal. At the same time, the coal discharged from the filter cylinder 5 can be guided by the inside of the protective frame 6, reducing the probability of the coal splashing when discharged, thereby increasing the amount and collection efficiency of the coal falling into the collection frame 8.

[0033] After collecting a portion of coal in the collection frame 8, start motor 702. The output end of motor 702 will rotate slightly back and forth. When the output end of motor 702 rotates, it drives shaft 703 to rotate. When shaft 703 rotates, it drives connecting frame 704 and bearing frame 705 to rotate. This causes bearing frame 705 to drive collection frame 8 to rotate slightly back and forth, so that the coal in collection frame 8 can be spread evenly in collection frame 8 while rotating, further improving the collection effect. After the coal screening is completed, the coal remaining in filter cylinder 5 is taken out and then used for filling material. Then, L-shaped plate 706 and collection frame 8 are taken out to complete the screening work.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
