[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figure 1-2 The first embodiment shown is a coal crushing device for coal mining, comprising a housing 1, wherein a crushing roller assembly 2 for processing mined coal is provided on the upper inner side of the housing 1. The crushing roller assembly 2 is composed of a motor, a gear assembly, and two sets of crushing rollers. The motor is provided on the back side of the housing 1, and the two sets of crushing rollers are both rotatably connected to the upper inner side of the housing 1. The driving gear and the driven gear in the gear assembly are respectively coaxially fixedly connected to the two sets of crushing rollers, and the output end of the motor is coaxially fixedly connected to the driving gear.

[0021] An adjusting member 3 for handling residual coal ore attached to the device is provided on the right side of the shell 1. The adjusting member 3 is composed of an air compressor 31, a three-way valve 32, a conduit 33, and an air jet ring 34. The air compressor 31 and the three-way valve 32 are both arranged on the right side of the shell 1. The exhaust end of the air compressor 31 is fixedly connected to the three-way valve 32. The conduit 33 is fixedly connected to the three-way valve 32 and the air jet ring 34 respectively. The air jet ring 34 is arranged on the top edge of the shell 1. The lower end of the air jet ring 34 is provided with a plurality of air jet holes connected to the conduit 33; a discharge member 4 for discharging the crushed coal ore is provided at the bottom of the shell 1. The discharge member 4 is composed of a conveying shell, an auger, and a motor. The conveying shell is arranged at the bottom of the shell 1, and the motor is arranged on the back side of the conveying shell. The auger is rotatably connected to the inner end of the conveying shell and is coaxially fixedly connected to the output end of the motor;

[0022] A branch pipe 5 is fixedly connected to the right side of the three-way valve 32, a vortex tube 6 fixedly connected to the branch pipe 5 is provided on the left side of the shell 1, a cold air pipe 7 is provided on the right side of the vortex tube 6, and a barrier 8 for coal powder protection is provided on the top of the shell 1; an exhaust pipe is provided at the exhaust end of the air compressor 31, and a filter is provided at the end of the exhaust pipe away from the shell 1, a hot air pipe is provided on the left side of the vortex tube 6, and the exhaust end of the hot air pipe is away from the shell 1; when there is a gap in coal mine delivery, the air compressor 31 is turned on, and the air compressor 31 draws in and compresses air from a distance through the exhaust pipe, and then the compressed air is ejected through the three-way valve 32, the conduit 33, and the jet ring 34. The jet ring 34 ejects compressed air to blow on the inner wall of the shell 1 and the crushing roller in the crushing roller assembly 2, so as to promote the shedding of residual materials attached to the surfaces of both, thereby reducing the subsequent cleaning steps;

[0023] like Figure 1-3 The second embodiment shown is mainly different from the first embodiment in that:

[0024] The barrier 8 is composed of a receiving shell 81, an auxiliary jet ring 82, a rotating plate 83, a support rod 84, a slider 85, and a spring 86. The receiving shell 81 is arranged at the middle end of the top of the shell 1. The cold air pipe 7 is fixedly connected to the auxiliary jet ring 82. Two sets of rotating plates 83 are rotatably connected to the upper inner side of the receiving shell 81. Two sets of sliders 85 are slidably connected to the receiving shell 81. The auxiliary jet ring 82 is fixedly connected to the receiving shell 81 and is located on the lower side of the rotating plate 83. The upper oblique end of the support rod 84 is rotatably connected to a movable block slidably connected to the lower end of the rotating plate 83. The lower oblique end of the support rod 84 is rotatably connected to the slider 85. The bottom of the slider 85 is fixedly connected to the spring 86, and the spring 86 is fixedly connected to the receiving shell 81.

[0025] The coal mined from the coal mine is put into the middle end of the top of the receiving shell 81, and the coal pushes the rotating plate 83 open. The rotating plate 83 rotates and drives the slider 85 to slide downward through the movable block and the support rod 84. The slider 85 compresses the spring 86. When the rotating plate 83 loses pressure, the spring 86 cooperates with the slider 85, the support rod 84 and the movable block to drive the rotating plate 83 to reset. The crushing roller assembly 2 crushes the block coal that falls through the barrier 8. The reset rotating plate 83 can reduce the generation of broken coal in the device. To prevent dust leakage, when the rotating plate 83 is reset and the delivery of coal is suspended, the three-way valve 32 is reversed. At this time, the air compressor 31 generates compressed air which is injected into the vortex tube 6 through the three-way valve 32 and the branch pipe 5. The vortex tube 6 converts the compressed air into cold air and hot air through vortex conversion. The cold air is blown to the lower end of the rotating plate 83 through the cold air pipe 7 and the auxiliary jet ring 82 to promote dust falling. Due to the obstruction of the rotating plate 83, the cold air flows downward and absorbs heat and cools it when passing through the crushing roller assembly 2.

[0026] At the same time, the contents not described in detail in this specification belong to the existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0027] When in use, the user starts the crushing roller assembly 2 and the discharge piece 4, and puts the coal mined from the coal mine into the middle end of the top of the receiving shell 81. The coal pushes the rotating plate 83 open, and the rotating plate 83 rotates and drives the slider 85 to slide downward through the movable block and the support rod 84. The slider 85 compresses the spring 86. When the rotating plate 83 loses pressure, the spring 86 cooperates with the slider 85, the support rod 84, and the movable block to drive the rotating plate 83 to reset. The crushing roller assembly 2 crushes the block coal that falls through the barrier 8. The reset rotating plate 83 can reduce the device The dust generated by the internal crushing of the coal ore leaks, and the crushed coal ore falls into the conveying shell in the discharge piece 4. The auger driven by the motor in the conveying shell transports the coal ore to the recovery end. When the coal ore is delivered, the air compressor 31 is turned on. The air compressor 31 draws in and compresses the air from a distance through the exhaust pipe, and then the compressed air is ejected through the three-way valve 32, the conduit 33, and the jet ring 34. The jet ring 34 ejects compressed air to blow on the inner wall of the shell 1 and the crushing roller in the crushing roller assembly 2, promoting the shedding of residual materials attached to the surfaces of both, thereby reducing the subsequent cleaning steps.
