Description

Technical Field

[0001] The utility model relates to an intelligent distribution and feeding system for a foldable intensive tobacco flue-curing barn, belonging to the technical field of tobacco flue-curing equipment. Background Art

[0002] Flue-curing barns are an essential piece of infrastructure in flue-cured tobacco production. After being cured and tempered in the flue-cured barn, the tobacco develops its unique color, aroma, flavor, and shape, becoming a high-quality raw material that meets the needs of the tobacco industry. Therefore, the sophistication of the flue-curing barn directly affects the quality of the finished flue-cured tobacco.

[0003] During traditional tobacco curing, burners burn fuel to provide heat within the flue-curing barn, serving as the heat source for the tobacco leaves. However, the tobacco curing cycle is long, typically lasting 7-8 days. This requires a continuous fuel supply to maintain the required heat. Curing facilities are large, with some boasting over 100 flue-curing barns. The actual burner hopper capacity is small, requiring frequent manual loading. Curing in each flue-curing barn does not start and end at the same time, and inconsistent curing times result in inconsistent fuel consumption. A biomass bag weighs approximately 25 kg, and four bags fill a bucket. A bucket of 25 x 4 = 100 kg. A flue-curing barn consumes approximately 50 bags per curing cycle, or 50 x 25 = 1250 kg. This requires at least 12.5 manual loadings (1250 / 100 = 1250 / 100 = 12.5 times). All of the above results in a huge workload for manual loading, and the staff need to pay attention to the supply of fuel at all times, and replenish the fuel in time when the fuel is insufficient to ensure the normal baking work. The staff are often required to replenish the fuel at night, which increases manpower and material resources. If the fuel is insufficient, it will have a huge impact on the baking of tobacco leaves, seriously endangering the quality of the tobacco leaves after baking and causing property losses.

[0004] Patent document CN 220229247 U discloses a biomass fuel feeding mechanism for a dense baking room, comprising a storage box, an igniter disposed below the storage box, and a second fixed plate. The top outer wall of the second fixed plate is fixedly connected to a first motor, the output end of the first motor is fixedly connected to a first auger, the top outer wall of the second fixed plate is fixedly connected to a reinforcing column, one end of the reinforcing column is fixedly connected to the first fixed plate, and the circumferential inner wall of the first fixed plate is fixedly connected to a storage barrel. This device can automatically replenish biomass fuel without the need for manual addition by staff, reducing the staff's filling intensity. However, when the burner is working, it requires the use of multiple motors to complete the feeding, which has problems such as high cost, excessive weight, inability to transmit over long distances, and difficulty in maintenance.

[0034] The movable support frame 12 is a plurality of movable support frames 12 arranged at the lower part of the telescopic automatic unloading chute 3, and is used to realize the telescopic automatic unloading chute 3 to be extended or unfolded.

[0035] When not in use, the telescopic automatic unloading chute 3 can be retracted and placed on one side of the storage device 1. When in use, the telescopic automatic unloading chute 3 is unfolded through the movable support frame 12, and its delivery port is connected to the burner 5 of the intensive baking room. The fuel in the telescopic automatic unloading chute 3 can be automatically delivered into the burner under the action of gravity.

[0036] The mobile support frame 12 comprises a support frame 1201 composed of horizontal bars and telescopic vertical bars. The support frame 1201 is provided with rollers 1202 at its bottom and hingedly connected to a sloping plate 1203 at its top. The telescopic automatic unloading chute 3 is secured to the sloping plate 1203 via a pipe clamp 1024. The mobile support frame 12 can be manually propelled or automatically controlled by a motor to retract and extend the telescopic automatic unloading chute 3. The telescopic vertical bars can be electrically operated.

[0037] The storage device 1 includes a supporting truss 101 , a storage bin 102 is provided on the top of the supporting truss 101 , a feed port of the storage bin 102 is connected to the feeding mechanism 2 , and a discharge port is connected to a telescopic automatic unloading chute 3 .

[0038] The feeding mechanism 2 can be a feeding belt, a spiral lifting and feeding device, etc. Through the feeding mechanism 2 , the biomass fuel in the biomass fuel storage device can be lifted and added into the storage bin 102 .

[0039] The telescopic automatic unloading chute 3 includes a telescopic feed main pipe 301, the feed end of which is connected to the storage bin 102. The discharge end is equipped with several telescopic feed branches 302. The telescopic feed branches 302 are arranged to correspond to the number of row curing barns. The telescopic feed branches 302 are equipped with several feed ports connected to the burners 5 of the dense curing barns. The telescopic feed main pipe 301 and the telescopic feed branches 302 are arranged downwardly and obliquely toward the dense curing barns 4. This structure utilizes gravity for fuel transfer, reducing the problems of high cost, heavy weight, long-distance transmission problems, and difficult maintenance caused by complex equipment design.

[0040] In order to quickly connect the feeding port of the telescopic feed branch pipe 302 with the burner 5 of the intensive baking room, a quick connector 303 is provided at the feeding port. The quick connector 303 is a conical plug adapted to the feeding port of the burner 5 of the intensive baking room.
