The utility model discloses an anti-smoke-return automatic-stoking tobacco curing furnace. The anti-smoke-return automatic-stoking tobacco curing furnace comprises a furnace body and an automatic fuel coal adding device. The automatic fuel coal adding device is arranged on one side of the furnace body, and a manual fuel coal adding port and a slag outlet are formed in the other side of the furnace body. Two heat collecting boxes are arranged on the upper portion of the furnace body and communicated with the interior of the furnace body through hot air channels respectively. A plurality of corrugated radiating pipes are arranged between the two heat collecting boxes, and the two ends of each corrugated radiating pipe are communicated with the two heat collecting boxes respectively. The automatic fuel coal adding device comprises a hopper and an automatic feeding device, the hopper is communicated with the interior of the furnace body through a feeding pipe, the automatic feeding device comprises a feeding auger and a servo motor, one end of the feeding auger stretches into the feeding pipe, and the other end of the feeding auger penetrates through the hopper to be connected with a power output shaft of the servo motor. The feeding pipe arranged between the interior of the furnace body and the hopper and used for connecting the interior of the furnace body and the hopper is inclined downwards. The anti-smoke-return automatic-stoking tobacco curing furnace achieves automatic adding of fuel coal and avoids the problem of smoke return in the automatic coal fuel adding process.
