Description

Technical Field

[0001] The utility model relates to the technical field of mine crushing, in particular to a stone crushing device for mining machinery. Background Art

[0002] Mines include coal mines, metal mines, non-metallic mines, building materials mines and chemical mines, etc. The scale of mines (also known as production capacity) is usually expressed in annual output or daily output. The annual output is the amount of ore produced by the mine each year. According to the size of the output, it is divided into three types: large, medium and small. The size of the mine should be adapted to the economically reasonable service life of the mine. Only in this way can the capital construction cost be saved and the cost be reduced. In the process of mine production, the mined ore needs to be further crushed.

[0003] There are many existing technologies for mining crushing, such as:

[0004] According to the Chinese patent application No.: 202410047307.0, an L-shaped frame, a fixed plate, a crushing zone and a crushing mechanism are disclosed. In the present invention, the stone collides with the impact plate on the left V-shaped plate under the action of centrifugal force, thereby achieving the effect of crushing the stone. The stone that falls onto the conveying plate again collides with the impact plate on the right V-shaped plate as the conveying plate rotates. The impact plates on the two V-shaped plates are used to achieve repeated collision crushing of the stone, thereby improving the crushing efficiency and crushing effect of the stone. The stone that does not meet the crushing specifications stays in the inner arc area of ​​the arc plate three, and the conveying plate allows this part of the stone to continue to repeat the above-mentioned collision crushing operation with the impact plate on the V-shaped plate, that is, through multiple collision crushing operations, it is ensured that the stone can be crushed into the required size specifications, thereby improving the crushing effect of the stone.

[0005] The existing technology is not convenient for separating water and stone and reusing water resources after crushing. Since a large amount of ash will be generated in the crushing process, precipitation and dust removal are required. Mining may aggravate the regional water shortage problem and require a large amount of water, resulting in increased consumption of water resources and easily causing water source shrinkage. For some areas where water resources are already scarce, precipitation and dust removal will aggravate local water resource pressure and have a huge impact on the ecological environment. However, in view of this, we propose a stone crushing device for mining machinery. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Mines include coal mines, metal mines, non-metallic mines, building materials mines and chemical mines, etc. The scale of mines (also known as production capacity) is usually expressed in annual output or daily output. The annual output is the amount of ore produced by the mine each year. According to the size of the output, it is divided into three types: large, medium and small. The size of the mine should be adapted to the economically reasonable service life of the mine. Only in this way can the capital construction cost be saved and the cost be reduced. In the process of mine production, the mined ore needs to be further crushed.

[0025] See also Figure 1-Figure 4As shown, the present embodiment provides a stone crushing device for mining machinery, including a base 1. Considering that a large amount of dust will be generated during the stone crushing process, water and stone cannot be separated during the precipitation and dust removal process, and there will be impurities in the separated water, which is easy to block the water pipe 22. Therefore, the details are as follows: a water tank 2 is provided on the top of the base 1, and a water pump 21 is fixedly connected to the outer end of the water tank 2, and a water pipe 22 is threadedly connected to the top of the water pump 21, and a shunt pipe 23 is connected to one end of the water pipe 22 with a socket connection, and a side plate 11 is fixedly connected to the top of the base 1, and a threaded rod 31 is threadedly connected to the inner part of the side plate 11, and a sieve 3 is fixedly connected to one end of the threaded rod 31. A baffle 24 is fixedly connected, and a hole groove 25 is opened on the baffle 24. The water with impurities that leaks down is precipitated on the left side of the water tank 2, and there is a fine mesh on the hole groove 25 to prevent some impurities from entering the right side of the water tank 2, thereby realizing water reuse. The prior art is not convenient for water-stone separation and water resource reuse after crushing. Since a large amount of ash will be generated during the crushing process, precipitation and dust removal are used. Mining may aggravate the problem of regional water resource shortage, require a large amount of water sources, lead to increased water resource consumption, and easily cause water source shrinkage. For some areas where water resources are originally scarce, precipitation and dust removal will aggravate local water resource pressure.

[0026] The improvement of this embodiment is that:

[0027] During crushing, water in the water tank 2 is pumped out by the water pump 21 and evenly sprinkled on the stone crushing mechanism through the diverter pipe 23, thereby achieving the effect of reducing dust.

[0028] During water-stone separation, the crushed stones and water fall onto the sieve 3 together, and the water and stones are separated by the sieve 3. The water drops into the water tank 2, and the stones remain on the sieve 3. The water can be reused.

[0029] Taking into account that the holes of the sieve 3 are easily blocked, a support plate 12 is fixedly connected through the right end of the side plate 11, the other end of the threaded rod 31 is fixedly connected to the first motor 32, the other end of the first motor 32 is fixedly connected to the fixed plate 33, the bottom of the fixed plate 33 is fixedly connected to a slider 34, the outer surface of the slider 34 is slidably connected to the inside of the slide groove 13, the first motor 32 drives the threaded rod 31 to rotate left and right inside the side plate 11, and the threaded rod 31 drives the sieve 3 to move left and right, so as to prevent the holes of the sieve 3 from being blocked.

[0030] Considering that the sieve 3 is unstable when only fixed by the threaded rod 31, the upper end of the sieve 3 is rotatably connected to the rotating plate 35, and the top of the rotating plate 35 is rotatably connected to the shell 43, so that the sieve 3 can be stable and move left and right.

[0031] Considering that the stone is hard and cannot be crushed easily, a rotating shaft 4 is rotatably connected to the inside of the side plate 11, and a hammer head 41 is fixedly connected to the outer surface of the rotating shaft 4. The inertia hammer head 41 repeatedly hits the stone to achieve a crushing effect.

[0032] Taking into account that one rotating shaft 4 has no extrusion and crushing capabilities, a gear 42 is fixedly connected to the outer surface of one end of the rotating shaft 4, a second motor 410 is fixedly connected to one end of the rotating shaft 4, and the other end of the rotating shaft 4 is rotatably connected to the inside of the outer shell 43 and meshed with the gear 42, so that the two rotating shafts 4 move in opposite directions to achieve a crushing effect.

[0033] In summary, the working principle of this solution is as follows:

[0034] Connect the water pump 21 to the power supply, pump water out from the right side of the water tank 2, and sprinkle the water evenly on the top of the shell 43 through the shunt pipe 23. At this time, turn on the second motor 410, and realize the two shafts 4 to rotate inward at the same time through the gear 42 to achieve the crushing of the stones. Turn on the first motor 32, and drive the threaded rod 31 to rotate left and right inside the side plate 11 through the first motor 32, and drive the sieve 3 to move left and right through the threaded rod 31. The first motor 32, the fixed plate 33 and the slider 34 slide inside the slide 13, and the crushed stones will be on the sieve 3. The water will be recovered into the semi-enclosed water tank 2 through the holes of the sieve 3. When the water flows into the left side and settles, it will enter the right end through the hole slot 25 to achieve the reuse of water resources.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
