Description

Technical Field

[0001] The utility model belongs to the technical field of coal mining technology, and more specifically, particularly relates to a bidirectional cutting coal mining mechanism. Background Art

[0002] Coal mining equipment is required for coal mining. The coal mining equipment is equipped with a bidirectional cutting coal mining mechanism. The bidirectional cutting coal mining mechanism is equipped with two sets of cutting knives. The two sets of cutting knives mine coal from different directions and cut coal simultaneously during the back and forth movement, thereby improving the efficiency of coal mining of the coal mining equipment.

[0003] According to CN202321769456.5, the utility model discloses a cutting device for a coal mining machine, including a main box, a docking part, a first motor, a transmission assembly, a cutting wheel and a swing dust reduction mechanism. The utility model is provided with a swing dust reduction mechanism, and when the staff performs coal mining work through the cutting wheel, they can first dock the external water pipe with the water inlet of the water collecting pipe, and the nozzle can spray water to the cutting wheel, and then turn on the second motor to drive the rotating rod to rotate, thereby realizing the rotation of the long rod. During the rotation process, the long rod pushes the connecting seat to move horizontally, and the connecting seat can drive the push rod, and the push rod can drive the connecting block to swing, so as to realize the swing spraying of the nozzle, and can realize dust reduction work in a larger range and achieve better dust reduction effect.

[0004] Based on the above, the existing bidirectional cutting coal mining mechanism generally mines coal through a cutting knife. When the cutting knife rotates to cut the coal, the cutting knife will cause the coal to splash. When the workers are in the coal mining area, the coal is easy to splash onto the workers, which can easily cause injuries to the workers. When the splashing coal splashes onto the transmission parts of the coal mining mechanism, it is easy to affect the service life of the coal mining mechanism. Utility Model Content

[0014] The utility model adopts a rotating protection mechanism to achieve that when the coal cutting knife rotates to mine coal, the self-locking motor drives the rotating guard plate to rotate, and the rotating guard plate rotates to the position of the coal cutting knife. When the coal cutting knife rotates to mine coal and causes coal splashing, the splashed coal hits the inner lining baffle plate, and the inner lining baffle plate blocks the coal splashing.

[0015] The utility model adopts a downward pressure blocking mechanism to achieve the goal that when the upper coal mining body moves downward, the coal mining cutting knife drives the coal mining cutting knife to move downward to mine coal. When the coal mining body moves downward to a certain extent, the downward pressure sliding block is supported on the ground, which reminds the staff that the coal mining body has a large downward movement angle, thereby avoiding the problem that the coal mining body is damaged by the coal mining cutting knife due to the large downward movement angle of the coal mining body, affecting the service life of the coal mining cutting knife, and ensuring the safety of the use of the coal mining mechanism.
