Technical Field

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

[0002] Mineral fillers are usually made by crushing the original ore, and mining crushing equipment is needed to crush the ore. Since the ore will produce a lot of smoke and dust when it is fed, in order to reduce the pollution of the environment by the smoke and dust, there are now dust-reducing mining crushing equipment.

[0003] For example, the patent specification of an existing Chinese patent (publication number: CN215277578U) discloses a raw ore crushing device. Through the designed water tank, water pump, protective box, water guide block and water outlet head and other structures, it can effectively perform water spraying operation on the top of the crushing roller through multiple water outlet heads. Crushing rollers are rotatably connected to both sides of the inner cavity of the crushing box. Crushing teeth are provided at equal distances along a ring on the surface of the crushing roller, and a gap is left between every two adjacent crushing teeth.

[0004] However, in the implementation of relevant technologies, it was found that the raw ore crushing device of the above design has the following problems: although the mining crushing device can realize the dust reduction function at the same time when in use, the crushing structure and the dust reduction structure on the raw ore crushing device are not connected to each other, which requires two power sources (motor and water pump) to drive the crushing roller to operate and spray water respectively during use, which is not only costly but also troublesome for subsequent maintenance. In view of this, a mining crushing device is provided to overcome the above defects. Utility Model Content

One end of another crushing shaft 2 and one end of the rotating shaft 10 rotate through the crushing box 1 and the water inlet tank 7 respectively, and a transmission roller 13 is fixedly sleeved on them, and a belt 14 is tensioned and sleeved on the two transmission rollers 13;

[0023] A transmission shaft 16 is fixedly installed on the front side of the turntable 11, and a rotating member 17 is fixedly sleeved on the transmission shaft 16. A mounting seat 18 is fixedly installed on one side of the piston 12, and a pin is arranged in the mounting seat 18. The other side of the rotating member 17 is rotatably sleeved on the pin. A feed hopper 19 is fixedly inserted on the top of the crushing box 1, and a discharge port 20 is opened near the bottom of one side of the crushing box 1.

[0024] In the specific implementation, a large amount of mining stones are introduced into the crushing box 1 through the feed hopper 19, and then the motor 5 is turned on. Since the two gears 4 are meshed and connected, the two crushing rollers 3 rotate in opposite directions to crush the mining stones into small pieces. The small pieces of mining stones will slide out of the designated position outside the discharge port 20 along the inclined surface 21, so that the mining stones can be crushed conveniently. In addition, during the feeding and crushing of mining stones, since one of the crushing shafts 2 is connected to the rotating shaft 10 through the belt 14 and the two crushing rollers 3, turning on the motor 5 will also make the rotating shaft 10 rotate. The driving shaft 10 rotates, and the turntable 11 rotates accordingly and drives the rotating member 17 to push and pull the piston 12 to make a reciprocating motion in the water inlet tank 7. During this process, when the piston 12 moves to the right, the clean water in the water storage tank 15 will flow into the water inlet tank 7 through the water inlet 9. When the piston 12 moves to the left, the clean water will be sprayed out through the water inlet pipe 8 and the atomizing nozzle 6 and contact with the mine stone and smoke dust, thereby achieving the effect of dust reduction. In addition, when crushing the mine stone and reducing the dust, only a single motor 5 is used as a power source at the same time, which effectively reduces the cost of use.

[0025] As a further implementation scheme of the above technical scheme: an inclined surface 21 is arranged in the crushing box 1, a water storage port 22 is opened in the inclined surface 21, a filter screen 23 is embedded in the water storage port 22, a water storage tank 24 is opened on the front side of the crushing box 1, and the water storage tank 24 is connected to the water storage port 22.

[0026] In specific implementation, based on the above implementation, the smoke dust that contacts the clean water will become mud and pass through the filter 23 and flow into the water storage tank 24, which can be effectively collected.

[0027] As a further implementation of the above technical solution: a water receiving box 25 is slidably inserted in the water storage tank 24, a handle 26 is provided on the front side of the water receiving box 25, and an anti-slip pattern is provided on the outer surface of the handle 26. By pulling the handle 26, the water receiving box 25 can be driven to slide out of the water storage tank 24, and can be used to process mud, ensuring that the water receiving box 25 can be used normally.

[0028] As a further implementation of the above technical solution: a controller 27 is provided at the front side of the crushing box 1, and the controller 27 is electrically connected to the motor 5 and the atomizing nozzle 6. It is convenient for personnel to control the switch and operating state of the motor 5.

[0029] As a further implementation of the above technical solution: an observation glass 28 is inlaid on the front side of the crushing box 1, and a sealing strip is provided on the observation glass 28 to seal the gap at the connection between the observation glass 28 and the crushing box 1. It is convenient to observe the amount of muddy water in the water receiving box 25, so as to deal with it in time.

[0030] For the atomizing nozzle 6, a DLK22S electromagnetic atomizing spray gun can be used. The electromagnetic atomizing spray gun is specially manufactured for atomizing sprays that require high-speed and frequent switching. Together with the zator-specific control system, a spray gun response speed of 350 times / second can be achieved. Since the atomizing nozzle 6 belongs to the prior art, no further explanation will be given in this manual.

[0031] Working principle:

[0032] When using the utility model, firstly, the electrical appliances involved in the mining crushing device are connected to an external power source, and then a large amount of mining stones are introduced into the crushing box 1 through the feed hopper 19, and then the motor 5 is turned on. Since the two gears 4 are meshed and connected, the two crushing rollers 3 rotate in opposite directions to crush the mining stones into small pieces. The small pieces of mining stones will slide out of the designated position outside the discharge port 20 along the inclined surface 21, so that the mining stones can be crushed conveniently. In addition, during the feeding and crushing of mining stones, since one of the crushing shafts 2 is connected to the rotating shaft 10 through the belt 14 and the two crushing rollers 3, the turning on of the motor 5 will also cause the rotating shaft 10 to rotate. At this time The turntable 11 rotates accordingly and drives the rotating part 17 to push and pull the piston 12 to make reciprocating motion in the water inlet box 7. During this process, when the piston 12 moves to the right, the clean water in the water storage tank 15 will flow into the water inlet box 7 through the water inlet 9. When the piston 12 moves to the left, the clean water will be sprayed out through the water inlet pipe 8 and the atomizing nozzle 6 and contact with the mine stone and smoke dust, thereby achieving the effect of dust reduction. In addition, the above-mentioned use of only a single motor 5 can be used as a power source at the same time when crushing the mine stone and reducing the dust, which can effectively reduce the cost of use. In addition, the smoke dust that contacts the clean water will become mud and pass through the filter screen 23 to flow into the water storage tank 24 and the water receiving box 25, which can be effectively collected.
