[0025] Figures 1 to 6 It is the best embodiment of the utility model, and the following Figures 1 to 6 The utility model is further described.

[0026] A mobile stone crusher for mining comprises a crusher body 1, a feeding mechanism 3 and a dust collecting mechanism 4. The feeding mechanism 3 is fixedly arranged on the top of the crusher body 1, and the dust collecting mechanism 4 is arranged on the feeding mechanism 3.

[0027] The crusher body 1 adopts the crusher body in the prior art, and its specific structure is not described in detail here.

[0028] The feeding mechanism 3 includes a feeding hopper 31, and two protection components are arranged in the feeding hopper 31, and the two protection components are used to protect the gravel generated during crushing to prevent it from collapsing to the outside and causing damage. The dust collection mechanism 4 is used to clean the dust generated during feeding to prevent air pollution;

[0029] The protection component includes a mounting shaft 32, a limiting unit, and an elastic unit. Two transmission chambers are provided in the feed hopper 31. The inner walls of the two transmission chambers close to each other are provided with mounting holes. The mounting shaft 32 is rotatably installed in the two mounting holes. A sealing plate 33 is fixedly sleeved on the outer wall of the peripheral side of the mounting shaft 32. A slide groove is provided on the side of the sealing plate 33. A telescopic plate 34 is slidably installed in the slide groove through the limiting unit. Two rectangular grooves are provided on the inclined surface of the feed hopper 31. Square sliders 36 are slidably installed in the two rectangular grooves through the elastic unit. Connecting rods 39 are rotatably installed on the sides of the two square sliders 36. The other ends of the two connecting rods 39 are rotatably installed on the bottom of the sealing plate 33.

[0030] The dust suction mechanism 4 includes a rotating shaft 41, and a mounting groove is provided on the side of the feed hopper 31. The relative inner walls of the mounting groove are connected to the two transmission chambers through through holes. The rotating shaft 41 is rotatably installed in the two through holes. The rotating shaft 41 and the mounting shaft 32 are connected through a transmission unit. A winding roller 44 is fixedly sleeved on the outer wall of the circumference of the rotating shaft 41, and a wire rope 45 is fixedly provided on the winding roller 44. The other end of the wire rope 45 extends into the slide groove and is fixedly connected to a side of the telescopic plate 34. A dust suction hole is provided on the side of the feed hopper 31, and an exhaust assembly is provided on the side of the feed hopper 31.

[0031] The limiting unit includes two limiting shafts 35, and two limiting grooves are provided on the side of the telescopic plate 34. One end of the two limiting shafts 35 are fixedly installed on the inner wall of the side of the slide groove, and the other ends of the two limiting shafts 35 are respectively slidably installed in the two limiting grooves. Through the setting of the limiting shafts 35, the sliding of the telescopic plate 34 can be limited to prevent the telescopic plate 34 from directional deviation during the sliding process.

[0032] The elastic unit includes a tension spring 38, and a guide shaft 37 is fixedly installed on the relative inner walls of the rectangular groove. A guide hole is opened on the side of the square slider 36, and the guide shaft 37 is slidably installed in the guide hole. The tension spring 38 is sleeved on the outer wall of the guide shaft 37. Through the setting of the tension spring 38, the sealing plate 33 can be stretched when it is flipped. When the squeezing of the sealing plate 33 is released, it can be driven to reset through the elastic action of the tension spring 38.

[0033] The transmission unit includes two large gears 42 and two small gears 43. Specifically, the number of teeth on the large gear 42 is twelve times the number of teeth on the small gear 43. Every sixty degrees of rotation of the large gear 42 can drive the small gear 43 to rotate seven hundred and twenty degrees. The two large gears 42 are fixedly sleeved on the installation shaft 32, and the two small gears 43 are fixedly sleeved on the rotating shaft 41. The two large gears 42 are respectively meshed with the two small gears 43. Through the rotation of the sealing plate 33, the installation shaft 32 and the large gear 42 can be driven to rotate synchronously, so that through the meshing action of the large gear 42 and the small gear 43, the small gear 43, the rotating shaft 41, and the winding roller 44 are driven to rotate in the opposite direction synchronously to reel in the wire rope 45.

[0034] The exhaust assembly includes a filter box 47, which is fixedly mounted on the side of the feed hopper 31. The filter box 47 is connected to the dust suction hole. An activated carbon plate 48 is arranged in the filter box 47. An exhaust pipe is arranged on the inner wall of one side of the filter box 47. An air pump 49 is arranged on the exhaust pipe. Specifically, the air pump 49 is controlled by a PLC controller. With this arrangement, the dust generated when the stone is put into the filter box 47 can be absorbed through the suction effect of the air pump 49, so that the dust is adsorbed through the activated carbon plate 48, thereby playing a filtering role and greatly reducing the pollution to the air. Specifically, the activated carbon plate 48 can also be other filter materials that can adsorb dust.

[0035] The exhaust assembly also includes a filter plate 46, which is fixedly installed in the dust suction hole. The filter plate 46 is adapted to the filter box 47. A cleaning brush 410 is slidably installed in the dust suction hole. A lifting unit is provided at the bottom of the cleaning brush 410. The setting of the filter plate 46 can effectively prevent stones from entering the filter box 47 during feeding and causing damage to the internal components, thereby providing a certain degree of protection.

[0036] The lifting unit includes two racks 411. The bottom inner wall of the dust suction hole and the bottom inner wall of the installation groove are jointly provided with a lifting hole. The two racks 411 are slidably installed in the two lifting holes respectively. Two linkage gears 412 are fixedly sleeved on the peripheral outer wall of the rotating shaft 41. The two linkage gears 412 are respectively meshed and installed with the two racks 411. Such an arrangement can drive the linkage gears 412 to rotate when the rotating shaft 41 rotates, thereby driving the racks 411 and the cleaning brush 410 to move downward synchronously under the meshing action, thereby cleaning the surface of the filter plate 46, allowing dust to enter the filter box 47, thereby avoiding the influence of dust accumulation on the air intake effect.

[0037] In summary, when the utility model is in use, when the shovel delivers the ore into the feed hopper 31, the two sealing plates 33 can be driven to turn over synchronously in the opposite direction through the action of gravity, so that the stone enters the feed hopper 31. When the sealing plate 33 turns over, the square slider 36 is driven to slide along the rectangular groove through the action of the connecting rod 39, and the tension spring 38 is stretched. At the same time, it drives the mounting shaft 32 to rotate synchronously. Through the meshing of the large gear 42 and the small gear 43, the large gear 42 can drive the small gear 43 to rotate in the opposite direction when rotating, thereby driving the rotating shaft 41 and the winding roller 44 to rotate synchronously, winding the wire rope 45, and pulling the telescopic plate 34 to move into the slide groove to shrink it. When the stone falls into the feed hopper 31, the sealing plate 33 is reset by the elastic action of the tension spring 38, and the telescopic plate 34 is driven to reset synchronously under the meshing action of the large gear 42 and the small gear 43, so as to prevent its excessive length from contacting with the stone during resetting and causing jamming.

[0038] During the production process, the dust generated during feeding is absorbed by the air pump 49, and the protective function of the filter plate 46 can prevent larger stones from entering the interior and causing damage to the internal components of the filter box 47. When the rotating shaft 41 is rotating, it can drive the linkage gear 412 to rotate synchronously, and through its meshing action with the rack 411, it drives the rack 411 and the cleaning brush 410 to move downward synchronously, and brush the dust on the surface of the filter plate 46 into the filter box 47 for adsorption, so as to avoid dust accumulation affecting the air intake effect.

[0039] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
