DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In the following, the technical scheme in the embodiment of the disclosure will be clearly and completely described in combination with the attached drawings in the embodiment of the disclosure. Apparently, the described embodiment is only a part of the embodiment of the disclosure, but not all of the embodiment. Based on the embodiments in the disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection in the disclosure.

[0025] Referring to FIGS. 1-4, a green, safe and efficient mining device for a mine is provided, which includes a support frame 10, a crushing bin 20, a fixed jaw plate 30, a movable jaw plate 40, a cam roller 50, a movable jaw back plate 60, first springs 70 and a driving device. The support frame 10 is provided with an opening 11, the crushing bin 20 is installed on the support frame 10 and located above the opening 11. The fixed jaw plate 30 is vertically installed on a left side of an inside of the crushing bin 20, the movable jaw back plate 60 is installed at one side of the movable jaw plate 40. A top end of the movable jaw plate 40 is hinged to a right side of the crushing bin 20, the cam roller 50 is rotatably connected with the inside of the crushing bin 20 and is slidably connected with the movable jaw back plate 60. A pair of the first springs 70 are located at both sides of a bottom end of the movable jaw plate 40, ends of the first springs 70 are fixedly connected with the movable jaw plate 40, and other ends of the first springs 70 are fixedly connected with the inside of the crushing bin 20, the driving device is in transmission connection with the cam roller 50.

[0026] The driving device drives the cam roller 50 to rotate clockwise in the crushing bin 20, and the cam roller 50 applies force on the movable jaw back plate 60 during the rotation process, and the movable jaw back plate 60 applies force on the whole back of the movable jaw plate 40, so that the movable jaw plate 40 presses the ore between the movable jaw plate 40 and the fixed jaw plate 30 to generate pressure on the ore. Because the movable jaw plate 40 rotates around its top end at the same time, the shear force relative to the fixed jaw plate 30 is generated on the ore simultaneously. Further, with the repeated rotation of the cam roller 50 and the periodic pulling of the bottom end of the movable jaw plate 40 by the first springs 70, the movable jaw plate 40 will vibrate; and the pressure, shear force and vibration of the movable jaw plate 40 on the ore will jointly improve the crushing efficiency of the ore.

[0027] In an embodiment, the green, safe and efficient mining device for a mine further includes a screening device. The screening device includes a sieve plate 91, second springs 92 and a sieve plate shaft 93, the sieve plate shaft 93 is fixedly connected with an end of the sieve plate 91, two ends of the sieve plate shaft 93 pass through the crushing bin 20 and are rotatably connected with the crushing bin 20; a pair of the second springs 92 are located at both sides of the sieve plate 91, and ends of the second springs 92 are fixedly connected with a bottom end of the fixed jaw plate 30, and other ends of the second springs 92 are fixedly connected with the sieve plate 91.

[0028] The crushed ore falls onto the sieve plate 91, and the smaller volume ore passes through the sieve plate 91, while the larger volume ore stays on the sieve plate 91. When the gravity of the accumulated ore is greater than the pulling force of the second springs 92 on the left end of the sieve plate 91, the larger volume ore rolls outside of the crushing bin 20 to wait for re-crushing, and the screening device ensures the quality of ore crushing.

[0029] In an embodiment, the driving device includes a motor 81, a first belt 82, a first belt pulley 83 and a second belt pulley 84, an outer side wall of the crushing bin 20 is provided with a motor bracket 21, and the motor 81 is installed on the motor bracket 21; the first belt pulley 83 is installed at an output end of the motor 81, the second belt pulley 84 is installed on the cam roller 50, and both the first belt pulley 83 and the second belt pulley 84 are in transmission connection with the first belt 82. The driving motor 81 drives the cam roller 50 to rotate in the crushing bin 20 through the first belt 82, the first belt pulley 83 and the second belt pulley 84.

[0030] In an embodiment, the driving device further includes a second belt 85, a third belt pulley 86, a fourth belt pulley 87, a first gear 88 and a tooth-missing gear 89, the third belt pulley 86 and the second belt pulley 84 are installed on the cam roller 50 side by side, the fourth belt pulley 87 is rotatably connected to an side wall of the crushing bin 20, and both the third belt pulley 86 and the fourth belt pulley 87 are in transmission connection with the second belt 85. The tooth-missing gear 89 is fixedly installed on a wheel axle of the fourth belt pulley 87, the first gear 88 is fixedly installed on the sieve plate shaft 93, and the tooth-missing gear 89 is meshed with the first gear 88 for transmission. The second belt pulley 84 and the third belt pulley 86 are fixed on the cam roller 50 meanwhile, and the motor 81 drives the tooth-missing gear 89 to rotate through the third belt pulley 86, the second belt 85 and the fourth belt pulley 87 simultaneously, and the tooth-missing gear 89 is periodically meshed with the first gear 88 to drive the sieve plate 91 to be periodically opened, thereby discharging the larger volume ore.

[0031] In an embodiment, the green, safe and efficient mining device for a mine further includes a dust removal device. The dust removal device includes a dust removal cover 101, and the dust removal cover 101 is installed at a top end of the crushing bin 20 and above the fixed jaw plate 30 and the movable jaw plate 40. The dust removal cover 101 prevents dust generated when ore is crushed from entering the air and polluting the environment.

[0032] In an embodiment, a dust removal curtain 102 is arranged in the dust removal cover 101. The dust removal curtain 102 can further prevent the dust in the dust removal cover 101 from overflowing.

[0033] In an embodiment, the dust removal device further includes a cyclone separation device 103, the side wall of the crushing bin 20 is provided with a dust removal opening 12, and the cyclone separation device 103 is communicated with the dust removal opening 12.
