Embodiment Construction
[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0024] Such as Figure 1 to Figure 4 As shown, a combined tamping mechanism for coal mine gangue filling includes a top beam 1, a base 2, and several lifting cylinders 3 arranged between the top beam 1 and the base 2; the two ends of the lifting cylinder 3 Rotate and install on the top beam 1 and the base 2 respectively; one end of the base 2 is provided with a lower tamping mechanism 4, and one end of the top beam 1 is provided with an upper tamping mechanism...

The invention discloses a coal mine gangue filling combined tamping mechanism which comprises a top beam, a base and a plurality of lifting oil cylinders arranged between the top beam and the base. The two ends of the lifting oil cylinder are rotationally mounted on the top beam and the base respectively; a lower tamping mechanism is arranged at one end of the base, and an upper tamping mechanismis arranged at one end of the top beam. Through cooperation of the upper tamping mechanism and the lower tamping mechanism, the working blind area of the lower tamping mechanism is eliminated, the upper tamping mechanism and the lower tamping mechanism work together, full-section tamping is achieved, the tamping effect is better, gangue filling combination tamping is tighter, the filling rate is increased, and surface subsidence reduction and working face safety management are facilitated; and by arranging the upper tamping mechanism, the elongation of the lower tamping mechanism is reduced, and the working face empty top distance is effectively reduced.
Description
technical field [0001] The invention belongs to the technical field of coal mine gangue filling equipment, and in particular relates to a coal mine gangue filling combined compacting mechanism. Background technique [0002] With the acceleration of urbanization and urbanization, the phenomenon of coal resource overburden is becoming more and more serious, resulting in a sharp decrease in the total amount of mine resources and restricting the sustainable development of mines. At the same time, due to the strengthening of environmental protection, it is more difficult to deal with the discharge of coal gangue. In summary, these factors restrict the life and normal operation of the mine. The gangue filling support is the core equipment of filling mining, and the support tamping mechanism is the key to the filling effect. The existing tamping mechanism has disadvantages such as low filling rate in the blind area, high tamping operation times and low efficiency, and long tampin...
