Integrated furnace bridge for sealing and discharging coal for household briquette furnace

Abstract

The invention discloses a fire banking and coal arrangement integrated furnace bridge of a household coal furnace. The furnace bridge consists of three parts of a fixed base, a mobile platform and a driving device; the fixed base comprises a fixed frame, a connecting plate and a furnace core base plate; the mobile platform comprises a strip tooth guide rail, a furnace bridge grating and a fire banking plate; the driving device comprises a rocking handle, rollers, a roller shaft, gears, a gear shaft and the strip tooth guide rail; two rollers are fixedly connected to the fixed frame through the two ends of the roller shaft, and two gears are fixedly connected through the gear shaft; the gears and the gear shaft are fastened; the furnace core base plate and the fixed frame are fastened by the connecting plate; the cross section of the strip tooth guide rail is a "" type guide rail groove; the guide rail groove is stretched above the rollers and the gears for cutting and engagement; the rocking handle is rotated; and the gears are rotated to engage with the strip tooth guide rail for guide translation. The furnace bridge is simple in structure; the gear engagement structure saves more power; the rocking handle is rotated to a fire banking position for coal arrangement; the rocking handle is reversely rotated to a combustion position for coal burning; an automatic ascending device can improve the fire banking capacity after a fire banking plate is in position; and the firepower can be precisely controlled through fine adjustment of the position of the rocking handle in the fire banking state.

Description

technical field [0001] The invention belongs to the technical field of household coal-burning furnaces, and in particular relates to an integrated furnace bridge for sealing fire and discharging coal of household briquette furnaces. Background technique [0002] The structure of the existing household coal stove bottom fire sealing device is complicated, and the fire sealing and coal discharge are usually controlled separately, which is inconvenient to operate, affects the appearance, and the fire sealing time is short. Contents of the invention [0003] The present invention aims to solve the technical problems that the existing household coal furnace bottom fire sealing device has a complex structure, and the fire sealing and coal discharge are usually controlled separately, which is inconvenient to operate, affects the appearance, and has short fire sealing time. [0004] In order to solve the problems of the technologies described above, the present invention adopts th...
