5. The mining machine having the curved auxiliary rocker arm capable of loading material of claim 3, wherein the reciprocating impact power box comprises an impact head, the linear distance between the master rocker arm and the impact head is larger than 200mm, the material punched by the reciprocating impact power box smoothly flows out from a gap between the master rocker arm and the impact head to enter the conveyor, and the material punched by the impact head is pushed into the conveyor through the auxiliary rocker arm material-loading member.

6. The mining machine having the curved auxiliary rocker arm capable of loading material of claim 3, wherein the master rocker arm is provided with an upper curved section of the master rocker arm, and the upper curved section of the master rocker arm and the curved auxiliary rocker arm curved downwards are beneficial for the auxiliary rocker arm material-loading member to smoothly push the material into the conveyor.

7. The mining machine having the curved auxiliary rocker arm capable of loading material of claim 4, wherein the material baffle comprises a bottom material baffle and a back material baffle, when the reciprocating impact box is at a low position, the bottom material baffle is flush with the bottom surface of the reciprocating impact box, or the side of the bottom material baffle close to the conveyor inclines upwards for a certain angle that facilitates the material climbing into the conveyor along the inclined bottom material baffle, the back material baffle is obliquely disposed at the back end of the bottom material baffle, one side of the back material baffle is close to the reciprocating impact box, and the bottom material baffle and the back material baffle are separately connected or are integrated.

8. The mining machine having the curved auxiliary rocker arm capable of loading material of claim 4, wherein a tongue plate is disposed at the front portion of the material shovel plate, the upper end of the tongue plate is close to the upper surface of the material removal and loading box-supporting section, and the lower end of the tongue plate is close to the lower surface of the material removal and loading box-supporting section, so as to conveniently shovel the material.

9. The mining machine having the curved auxiliary rocker arm capable of loading material of claim 7, wherein the junction of the bottom material baffle and the back material baffle is an arc-shaped transition and/or the material blocking surface of the back material baffle is a curved surface, and the curved surface comprises a paraboloid, hyperboloid or a special-shaped curved surface.

10. The mining machine having the curved auxiliary rocker arm capable of loading material of claim 3, wherein the shape of the section of the curved auxiliary rocker arm comprises a circle, an oval, a square, a rectangle, a triangle, a polygon or a special shape.

11. The mining machine having the curved auxiliary rocker arm capable of loading material of claim 3, wherein the auxiliary rocker arm material-loading member and the curved auxiliary rocker arm are separately connected or are integrated, and the auxiliary rocker arm material-loading member is convenient to adjust and change in the case of separate connection.

12. The mining machine having the curved auxiliary rocker arm capable of loading material of claim 3, wherein the reciprocating impact box comprises an impact head, and the length of the lower curved section of the curved auxiliary rocker arm is larger than that of the impact head disposed near the curved auxiliary rocker arm, in order to avoid the lower curved section blocking the material flow.

13. The mining machine having the curved auxiliary rocker arm capable of loading material of claim 7, wherein the width of the back material baffle is larger than or equal to that of the bottom material baffle, in order to push the material into the conveyor.
