Description

Technical Field

[0001] This utility model relates to the field of biomass fuel production technology, and in particular to a feeding device for biomass fuel production. Background Technology

[0002] Biomass fuel refers to fuel made by burning biomass materials, mainly agricultural and forestry waste such as straw, sawdust, bagasse, and rice husks. It is mainly different from fossil fuels. According to national policies and environmental standards, direct combustion of biomass is considered a high-pollution fuel and is only allowed to be used in rural stoves, not in cities. The actual application of biomass fuel is mainly biomass briquettes, which are made by crushing, mixing, extruding, and drying agricultural and forestry waste as raw materials to produce various shapes such as blocks and pellets, which can be directly burned.

[0003] However, in the existing technology, biomass fuel production usually involves manually feeding or using a screw conveyor to transport raw materials to the combustion device. Manual feeding is time-consuming, labor-intensive, and inefficient. While screw conveyors can effectively transport fuel, they are generally large and have a fixed design, making it difficult to move them according to work requirements. Furthermore, the conveying height is usually fixed and cannot be adjusted according to the height of the combustion device, making them unsuitable for different equipment and inconvenient for users. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a feeding device for biomass fuel production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a feeding device for biomass fuel production, comprising: a base plate, four casters rotatably mounted on the bottom of the base plate, a feeding structure and an adjustment structure provided on the top of the base plate, the feeding structure including a movable frame, two support frames fixedly mounted on the top of the movable frame, two sprockets rotatably mounted on one side of each of the two support frames, the four sprockets forming a group of two, chains sleeved on the outer sides of each group of sprockets, fixed seats fixedly mounted on one side of each of the two chains, a rotating shaft rotatably mounted between the two fixed seats, a feeding frame fixedly mounted on the outer side of the rotating shaft, and guide frames fixedly mounted on the front sides of each of the two support frames.

[0006] In a preferred embodiment, both guide frames are provided with guide grooves, and sliding columns are rotatably installed on both sides of the feeding frame. The two sliding columns are respectively disposed inside the two guide grooves and slide in contact with the two guide frames.

[0007] In a preferred embodiment, a limiting block is fixedly installed at one end of each of the two sliding columns, and the radius of the limiting block is larger than the radius of the sliding column.

[0008] In a preferred embodiment, a connecting shaft is fixedly installed between the two sprockets, and a No. 1 motor is fixedly installed on one side of one of the support frames. The output end of the No. 1 motor passes through one of the support frames and is fixedly connected to one of the sprockets.

[0009] In a preferred embodiment, the adjustment structure includes two fixed frames, both of which are fixedly installed on the top of the base plate. Gears are rotatably installed on the inner side of each of the two fixed frames, and racks are meshed with the outer side of each of the two gears. A connecting plate is fixedly installed on one side of each of the two racks, and one side of each connecting plate is fixedly connected to the movable frame.

[0010] In a preferred embodiment, the two racks pass through the top of the two fixing frames and slide in contact with the two fixing frames respectively. The front side of each of the two fixing frames is provided with a rectangular sliding groove. The two connecting plates are respectively disposed inside the two rectangular sliding grooves and slide in contact with the two fixing frames respectively.

[0011] In a preferred embodiment, a rotating rod is rotatably mounted between the two fixed frames. The two ends of the rotating rod pass through one side of the two fixed frames and are fixedly connected to two gears respectively. A second motor is fixedly mounted on one side of one of the fixed frames, and the output end of the second motor passes through one of the fixed frames and is fixedly connected to one of the gears.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. This utility model uses two sets of sprockets to drive two chains to move, causing two fixed seats and the rotating shaft between them to move upward, thereby driving the feeding frame upward. Two sliding columns will slide inside the two guide grooves. When the two sliding columns move to the arc path of the two guide grooves, the feeding frame will slowly change from a vertical state to an inclined state, thereby pouring out the material inside the feeding frame for feeding. No manual feeding operation is required. The structure is simple and the device is easy to move and transport according to the usage. It improves work efficiency while keeping costs low.

[0014] 2. The second motor drives one of the gears to rotate, which in turn drives the rotating rod to rotate, which in turn drives the other gear to rotate, thereby causing the two racks to mesh and move synchronously. This, in turn, drives the moving frame and the feeding frame on top of it to change their height accordingly through the two connecting plates. This allows the device to be adjusted according to the height of the feeding equipment, effectively improving the applicability of the device. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] like Figure 1-4As shown, this utility model provides a technical solution: a feeding device for biomass fuel production, comprising: a base plate 11, four casters 12 rotatably mounted on the bottom of the base plate 11, a feeding structure 2 and an adjustment structure 3 provided on the top of the base plate 11, the feeding structure 2 including a movable frame 21, two support frames 22 fixedly mounted on the top of the movable frame 21, two sprockets 23 rotatably mounted on one side of each of the two support frames 22, the four sprockets 23 being in pairs, chains 24 being sleeved on the outer sides of each pair of sprockets 23, fixed seats 25 fixedly mounted on one side of each of the two chains 24, a rotating shaft 26 rotatably mounted between the two fixed seats 25, and a feeding frame 27 fixedly mounted on the outer side of the rotating shaft 26. Guide frames 28 are fixedly installed on the front side of both support frames 22. Guide grooves 29 are opened on both guide frames 28. Sliding columns 210 are rotatably installed on both sides of the feeding frame 27. The two sliding columns 210 are respectively set inside the two guide grooves 29 and slide in contact with the two guide frames 28 respectively. Limiting blocks 211 are fixedly installed at one end of the two sliding columns 210. The radius of the limiting blocks 211 is larger than the radius of the sliding columns 210. A connecting shaft 212 is fixedly installed between the two sprockets 23. A No. 1 motor 213 is fixedly installed on one side of one of the support frames 22. The output end of the No. 1 motor 213 passes through one of the support frames 22 and is fixedly connected to one of the sprockets 23.

[0028] In this embodiment, the guide groove 29 and the sliding column 210 inside it guide the movement of the sliding column 210, thereby driving the feeding frame 27 to move in the corresponding direction. The path of the guide groove 29 is first a straight line and then an arc. In the straight state, when the two chains 24 drive the feeding frame 27 between the two chains 24 to move upward, the guide groove 29 on the straight path will limit the sliding column 210 to the left and right, so that the feeding frame 27 maintains a vertical state and moves upward. When it moves to the arc path of the guide groove 29, it is affected by the arc path of the guide groove 29. The sliding column 210 will be blocked and unable to move upward. Instead, as the feeding frame 27 moves upward, its angle will gradually change, causing the two sliding columns 210 to move along an arc path. When it moves to the end of the arc path, the angle of the feeding frame 27 will be close to 90 degrees, so that the material inside the feeding frame 27 can be poured out. The set limiting block 211 can effectively limit the position of the two sliding columns 210 and the feeding frame 27 between them, ensuring that the feeding frame 27 will not sway left and right, and ensuring that the movement of the feeding frame 27 and its feeding position are in an accurate state.

[0029] Example 2

[0030] like Figure 1 , 2As shown in Figures 5 and 6, the adjustment structure 3 includes two fixed frames 31, both of which are fixedly mounted on the top of the base plate 11. Gears 32 are rotatably mounted on the inner side of each of the two fixed frames 31, and racks 33 are meshed with the outer side of each of the two gears 32. Connecting plates 34 are fixedly mounted on one side of each of the two racks 33, and one side of each connecting plate 34 is fixedly connected to the movable frame 21. The two racks 33 pass through the top of each of the two fixed frames 31 and slide in contact with each of the two fixed frames 31. Rectangular grooves 35 are opened on the front side of each of the two fixed frames 31. The two connecting plates 34 are respectively set on the inner side of the two rectangular grooves 35 and slide in contact with each of the two fixed frames 31. A rotating rod 36 is rotatably mounted between the two fixed frames 31. The two ends of the rotating rod 36 pass through one side of each of the two fixed frames 31 and are fixedly connected to the two gears 32. A second motor 37 is fixedly mounted on one side of one of the fixed frames 31. The output end of the second motor 37 passes through one of the fixed frames 31 and is fixedly connected to one of the gears 32.

[0031] In this embodiment, the rack 33 passes through the fixed frame 31, which can effectively limit the position of the rack 33, ensuring that the rack 33 can always maintain a meshing connection with the gear 32 and avoid disengagement between the gear 32 and the rack 33. On the other hand, it can prevent the fixed frame 31 from obstructing the movement of the rack 33, ensuring that when the gear 32 rotates, it can stably drive the rack 33 and the moving frame 21 on one side to move up and down to adjust the feeding height of the feeding frame 27. The rectangular slide 35 can effectively limit the connecting plate 34, ensuring that the connecting plate 34 can slide inside the rectangular slide 35 to drive the moving frame 21 to move up and down. The rotating rod 36 can make the two gears 32 rotate synchronously, thereby ensuring that the moving frame 21 will not tilt or get stuck during lifting and lowering.

[0032] Working principle:

[0033] like Figure 1-6As shown, during use, the base plate 11 is pushed to the desired feeding position, and then the material is poured into the feeding frame 27. Then, the first motor 213 is started. (The specific model of the first motor 213 is not described here; the model should be determined based on the compatible equipment.) The first motor 213 will drive one of the sprockets 23 to rotate, which in turn drives the other sprocket 23 to rotate via the connecting shaft 212. This causes the two chains 24 to move, resulting in the two fixed seats 25 and the rotating shaft 26 between them moving upwards, thus moving the feeding frame 27 upwards. The two sliding columns 210 will slide inside the two guide grooves 29. When the two sliding columns 210 move to the arc path of the two guide grooves 29, they are blocked by the guide grooves 29. One side of the feeding frame 27 will continue to move upward, while the other side will change angle, slowly changing from a vertical state to an inclined state. When it moves to a position close to the high point, the feeding frame 27 will be in an inclined state, thereby pouring out the material inside the feeding frame 27 for feeding. After feeding is completed, the No. 1 motor 213 can be started in reverse to reset. No manual feeding operation is required. The structure is simple and easy to move and transport the device according to the usage. It improves work efficiency while keeping costs low.

[0034] When the height of the feeding position needs to be adjusted, the second motor 37 is started. The specific model of the second motor 37 is not described here, but is based on the compatible equipment. The second motor 37 will drive one of the gears 32 to rotate, which in turn drives the rotating rod 36 to rotate, which in turn drives the other gear 32 to rotate, thereby driving the two racks 33 to mesh and move synchronously. Through the two connecting plates 34, the height of the moving frame 21 and the feeding frame 27 on top of it will change accordingly. This allows the device to be adjusted according to the height of the required feeding equipment, effectively improving the applicability of the device.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
