Description

TECHNICAL FIELD

[0001] The utility model relates to a biomass curing barn spiral feeding device and belongs to the technical field of biomass curing barn. BACKGROUND

[0002] In the baking process of the biomass curing barn, biomass particles are used as fuel. In the tobacco baking process, biomass particle fuel needs to be delivered to the hearth of the combustion chamber for combustion. The current feeding mode is an external hanging type bin, that is, a bin is installed outside the combustion chamber, and biomass material is delivered to the hearth for combustion by gravity or a conveyor. This mode is suitable for the feeding mode of continuous heating by open flame. However, when the biomass curing barn uses biomass particle fuel, manpower is often used to lift 50 kg of particle material from the ground into a hopper above 1.6 meters for feeding, which is laborious and time-consuming. SUMMARY

[0003] Based on the above, the utility model provides a biomass curing barn spiral feeding device to overcome the shortcomings of the prior art.

[0004] The technical scheme of the utility model is: a biomass curing barn spiral feeding device, comprising:

[0005] A feeding unit, comprising a rack, a feeding cylinder vertically installed on the rack, a spiral auger rotatably installed in the feeding cylinder, and a discharge cylinder installed at the top of the feeding cylinder in a downward inclined posture;

[0006] A distribution unit, comprising a distribution bin installed on the side of the lower part of the feeding cylinder, a rotating shaft rotatably installed in the distribution bin, and distribution plates spaced apart circumferentially on the rotating shaft, the upper end of the distribution bin away from the feeding cylinder is provided with a feeding hopper, and the bottom of the end of the distribution bin close to the feeding cylinder is provided with an inclined channel connected with the feeding port of the feeding cylinder.

[0007] In one example, a driving motor is further installed on the rack, and the driving motor is connected with the rotating shaft and the spiral auger through a transmission component.

[0008] In one example, the transmission component comprises a first belt disc installed on the output shaft of the driving motor, a second belt disc and a third belt disc installed on the lower end of the rotating shaft, and a fourth belt disc installed on the lower end of the feeding cylinder, and a transmission belt is arranged between the first belt disc and the second belt disc, and between the third belt disc and the fourth belt disc.

[0009] In one example, the driving motor is a speed reducer.

[0010] In one example, universal wheels are installed on the bottom of the rack.

[0011] In one of the examples, the feeding hopper is in a square discharge hopper structure.

[0012] In one of the examples, the frame is provided with a handrail.

[0013] The beneficial effects of the utility model are as follows: the device is moved to the side of the biomass curing barn material box during replenishment, and the discharge cylinder is located above the material box, biomass material enters the distribution box through the feeding hopper, fills the cavity composed of adjacent distribution plates, and when the distribution plate rotates to the side close to the feeding cylinder, the biomass material enters the lower part of the feeding cylinder through the inclined channel, is gradually conveyed to the upper part by the spiral auger, and falls into the material box through the discharge cylinder, thereby completing the replenishment operation.
