Abstract
Description
Technical Field
[0001] This utility model relates to tobacco curing equipment, and in particular to a fuel dispensing device for a dense curing barn. Background Technology
[0002] The existing dense curing barns are arranged in rows, and each barn has a tobacco curing furnace hopper at the front. During the tobacco curing process, biomass fuel needs to be added to each hopper frequently. When adding biomass fuel to the hopper, the feeding port of the hopper is higher than an adult's shoulder, so a ladder is needed. In addition, the biomass fuel is piled up in a unified manner and needs to be transported to each hopper. Therefore, adding biomass fuel to the hopper is time-consuming, laborious, and poses safety hazards. Utility Model Content
[0003] In view of this, the purpose of this utility model is to provide a fuel dispensing device for a dense drying room to solve the technical problems mentioned in the background art.
[0004] The objective of this utility model is achieved through the following technical solution:
[0005] A fuel dispensing device for intensive curing barns includes two conveyor chains, each comprising an incline section and a transverse section. The lower end of the incline section is located at the fuel storage area, and the upper end connects to the transverse section. The transverse section is located above the hoppers of the tobacco curing furnaces arranged in rows at the front. The two conveyor chains are arranged side by side in the front-back direction and move synchronously. The two conveyor chains are connected by multiple connectors, and each connector is equipped with a hanging assembly for hanging bagged biomass fuel.
[0006] Furthermore, each conveyor chain includes a chain and a sprocket assembly. The chain drive is sleeved on the sprocket assembly. The sprocket assembly includes at least three sprockets and a tensioning wheel. One of the at least three sprockets is fixedly sleeved on the rotating shaft at the fuel storage area, and the other two sprockets are rotatably sleeved on the support shafts at both ends of the front side of multiple dense curing barns arranged in rows. The support shafts are vertically fixed on the dense curing barns. The rotating shaft is rotatably mounted on the frame and connected to the drive mechanism. The tensioning wheels of the two conveyor chains are rotatably sleeved on two mounting shafts on the front side of the dense curing barns near the fuel storage area. The two mounting shafts are respectively connected to the support rods on their upper sides through connecting rods. The support rods are vertically fixed on the dense curing barns.
[0007] Furthermore, the drive mechanism is connected to a controller, and the controller is connected to a remote controller.
[0008] Furthermore, the connector is a connecting rod, and both ends of the connecting rod are fixed to the chains of the two conveyor chains respectively.
[0009] Furthermore, the hanging assembly is a hook, and the upright section of the hook is vertically fixed to the connecting rod.
[0010] The beneficial effects of this utility model are:
[0011] The fuel feeding device for intensive curing barns proposed in this utility model suspends bagged biomass fuel on a hanging assembly at the fuel storage location. Two conveyor chains can transport the bagged biomass fuel directly above the hopper of each intensive curing barn's tobacco curing furnace. The bagged biomass fuel can be opened for feeding, which is time-saving, labor-saving, and poses no safety hazards.

[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.
[0021] like Figure 1-5The fuel dispensing device for the dense curing barns shown includes two conveyor chains 1. Each conveyor chain 1 includes an incline section and a transverse section. The lower end of the incline section is located at the fuel storage area, and the upper end connects to the transverse section. The transverse section is located above the tobacco curing hoppers 3 on the front side of multiple dense curing barns 2 arranged in rows. The two conveyor chains 1 are arranged side by side in the front-back direction and move synchronously. Each conveyor chain 1 includes a chain 4 and a sprocket assembly. The chain 4 is driven and sleeved on the sprocket assembly. The sprocket assembly includes at least three sprockets 5 and a tension wheel 6. One of the at least three sprockets 5 is fixedly sleeved on the rotating shaft 7 at the fuel storage area, two sprockets 5 are rotatably sleeved on the support shafts 8 at both ends of the front side of the multiple dense curing barns 2 arranged in rows, and the remaining sprockets 5 are set... The two chain wheels 5 on the front side of the intensive drying chamber 2 are connected to the intensive drying chamber 2 via a support shaft 8. The support shaft 8 is vertically fixed to the intensive drying chamber 2. The rotating shaft 7 is rotatably mounted on the frame 9 and connected to a drive mechanism (not shown in the figure). The drive mechanism includes a motor, the output shaft of which is connected to a reducer, and the output shaft of the reducer is connected to the rotating shaft. The drive mechanism is also connected to a controller, which is connected to a remote control. The tension wheels 6 of the two conveyor chains 1 are respectively rotatably mounted on two mounting shafts 10 on the front side of the intensive drying chamber 2 near the fuel storage area. The two mounting shafts 10 are respectively connected to the support rods 12 on their upper sides via connecting rods 11. The support rods 12 are vertically fixed to the intensive drying chamber 2. The connecting rods 11 vertically connect the mounting shafts 10 and the support rods 12. The chains 4 of the two conveyor chains 1 are connected by multiple spaced connectors 13. The connectors 13 have various structural forms, such as connecting rods. The two ends of the connecting rods are respectively fixed to the chains 4 of the two conveyor chains 1. The connector 13 is equipped with a hanging assembly 14, which can hang bagged biomass fuel. Preferably, the hanging assembly 14 is a hook, and the upright section of the hook is vertically fixed to the connecting rod.
[0022] In the normal state, the two conveyor chains 1 of this utility model's intensive tobacco curing barn fuel dispensing device are stopped. When a tobacco curing oven hopper 3 alarms due to insufficient fuel, the drive mechanism is controlled by a remote control to move the two conveyor chains 1. When a hook reaches the fuel storage area (if there is an empty bag on the hook, it is removed), the bagged biomass fuel (the bagged biomass fuel is in its original state after purchase) is hung on the hook. Then, the drive mechanism is controlled by the remote control to move the two conveyor chains 1, carrying the bagged biomass fuel uphill and then laterally until it reaches the alarmed tobacco curing oven hopper 2. The drive mechanism is then controlled by the remote control to stop the two conveyor chains 1. Finally, the woven bag of the biomass fuel is cut open with a knife to dispense the fuel.
[0023] The device is time-saving and labor-saving to use, and there are no safety hazards. The tension wheels 6 of the two conveyor chains 1 are connected to the dense drying room 2 through a special structure, which can avoid hooks and / or bagged biomass fuel.
[0024] It should be noted that, in addition to being started and stopped by remote control, the two conveyor chains 1 can also be started and stopped by directly switching the power on and off.
[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
