The full-automatic coke feeder of the disc valve type intelligent gas furnace as claimed in claim 2, characterized in that: the bottom end of a piston rod of the hydraulic oil cylinder a (16) is connected with the valve rod a (14) through a connecting clamping sleeve a (15); and a guide sleeve a (18) for guiding and sealing the valve rod a (14) is nested at the junction of the bracket (17) of the hydraulic oil cylinder a and the distributing barrel body (11).

7. The full-automatic coke feeder of the disc valve type intelligent gas furnace as claimed in claim 1, which is characterized in that: the disc valve (2) comprises a valve seat (21), a shell (22) integrally fixed on the top end face of the valve seat (21) and a top valve (215) detachably arranged at the top end of the shell (22), and through holes (214) used for enabling coal materials to fall are formed in the valve seat (21), the shell (22) and the top valve (215) in a penetrating mode; the disc valve plate (213) used for controlling whether the through hole (214) is opened or not is arranged in the shell (22) in a sealing mode, and the disc valve plate (213) is connected with a disc valve driving mechanism used for driving the linkage structure to move so as to realize the overturning action of the disc valve plate (213) and further control whether the disc valve is opened or not through the linkage structure.

8. The full-automatic coke feeder of the disc valve type intelligent gas furnace as claimed in claim 7, wherein: the linkage structure comprises a disc valve plate pin shaft (212) vertically and fixedly arranged in the middle of the disc valve plate (213), a large rocker arm (25) vertically fixed with the disc valve plate pin shaft (212) and positioned below the disc valve plate (213), a large shaft (24) vertically fixed with the large rocker arm (25) and arranged on the shell (22) through a bearing (29), and a small rocker arm (23) vertically fixed with the large shaft (24) and parallel to the large rocker arm (25), wherein one end of the small rocker arm (23) which is not fixed with the large shaft (24) is hinged with a hinge base (26).

9. The full-automatic coke feeder of the disc valve type intelligent gas furnace as claimed in claim 7, wherein: a transition sealing structure used for enabling the disc valve plate (213) to have a sealing effect, facilitating the disc valve plate (213) to turn over and reducing the abrasion of the disc valve plate (213) is arranged between the top valve (215) and the disc valve plate (213).

10. The full-automatic coke feeder of the disc valve type intelligent gas furnace as claimed in claim 1, which is characterized in that: the gate valve (3) comprises a valve body c (31) detachably connected and arranged on the disc valve (2), a gate valve plate (32) penetrating through the valve body c (31) and used for controlling whether the valve body c (31) is opened or not, and a gate valve driving mechanism which is connected and arranged on the side wall of the valve body c (31) and is detachably connected with the gate valve plate (32) through a piston rod end and used for driving the gate valve plate (32) to move.
