the coal mining machine comprises a base, wherein one side of the base is connected with the coal mining machine;
the support rods are arranged on the base, and the tops of the support rods are connected with the first fixing part.
5. The longwall face front mining frame rear synchronous paste filling apparatus of claim 2, wherein the baffle plate comprises:
a second fixing portion;
the second telescopic part is in telescopic connection with the second fixing part, and the second telescopic part can be in butt joint with the second end of the rear tail beam plate.
6. The device for simultaneous front and rear paste filling of a longwall fully-mechanized mining face frame according to claim 1, further comprising a jack, a first end of the jack being connected to the bracket, a second end of the jack being in abutment with the baffle.
7. The longwall face frame front mining frame rear synchronous paste filling device of claim 1, wherein the membrane body comprises:
the first end of the first film body is paved along the top surface of the filling area;
and the first end of the second film body is paved along the bottom surface and the side surface of the filling area, and the second film body paved along the side surface of the filling area can be attached to the baffle plate.
8. A method of performing longwall fully-mechanized face frame front mining frame rear synchronous paste filling using the longwall fully-mechanized face frame front mining frame rear synchronous paste filling apparatus of any one of claims 2-7, comprising:
paving a film body into the first filling area to form a first closed space, and filling paste into the first closed space;
controlling the action of the coal mining machine to mine the coal body;
when the coal mining machine drives the support to move along a first direction, the second end of the rear tail beam plate automatically stretches, so that the baffle plate is abutted with the second end of the rear tail beam plate, and the first direction is the pushing direction of coal mining.
9. The method of longwall fully mechanized mining face pre-frame post-frame synchronized paste filling of claim 8, wherein prior to the step of filling the first enclosed space with paste, the method further comprises:
and controlling the jack to stretch and retract so as to enable the jack to be abutted with the baffle.
10. The method of longwall fully mechanized mining face frame front mining frame rear synchronized paste filling of claim 8, further comprising:
after the first closed space is filled with paste, controlling the baffle to move a preset distance along the first direction so as to form a second filling area in the area between the baffle and the first closed space;
paving the film body into the second filling area to form a second closed space;
filling paste into the second enclosed space, and simultaneously controlling the coal mining machine to continue to mine the coal mining body;
and repeating the steps in sequence until the coal mining is completed.
