Description

Technical Field

[0001] The utility model belongs to the technical field of chemical fertilizer production, and particularly relates to a powder feeding device. Background Art

[0002] In the process of chemical fertilizer production, as the most common material in the processing process, when feeding powder into processing equipment for processing, it is usually fed into the hopper manually or automatically. As is well known, the design of the lower discharge port of the hopper with a smaller size not only facilitates feeding, but also can continuously discharge materials automatically after one-time feeding. However, when feeding powder, due to the fineness of the powder and the fact that the powder has a certain humidity, during feeding, the powder is likely to block at the lower discharge port, easily causing the downstream equipment to run idly and the production capacity to be unstable. Therefore, it is necessary to regularly dredge manually from above the hopper with hand tools, resulting in a waste of manpower. Therefore, there is an urgent need to provide a powder feeding device that can be automatically dredged. Summary of the Utility Model

[0003] Aiming at the above deficiencies, the purpose of the utility model is to provide a powder feeding device, which solves the problem that the powder feeding device in the prior art is easy to block.

[0009] Preferably, driving wheels are provided on both the first drive shaft and the second drive shaft, and a plurality of mounting grooves are provided on the driving wheels, and the conveyor belt is arranged in the mounting grooves.

[0010] With the above structural design, by designing the connection method of multiple conveyor belts, the connection stability is strong, and when a single conveyor belt is damaged, the dredging roller will not stop working.

[0011] Preferably, a speed reducer is provided on the driving motor, and the output end of the speed reducer is connected to the first drive shaft.

[0012] With the above structural design, the feeding speed can be adjusted according to the feeding requirements of downstream materials, improving the practicability of the device.

[0015] Preferably, a plurality of dredging members are evenly arranged on the dredging roller, and the dredging members are made of hard materials.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model. In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model.

[0028] Please refer to Figures 1 to 3, a powder feeding device, including a mounting frame 1, on which a feeding channel 2 is provided. One end of the feeding channel 2 is connected to the downstream equipment, and an opening is provided above the other end and communicated with a hopper 3. A feeding screw 4 is arranged in the feeding channel 2, and one end of the feeding screw 4 is driven to rotate by a driving motor 5. At the discharging position below the hopper 3, a dredging roller 6 is provided, and dredging members 6a are arranged on the dredging roller 6. One end of the dredging roller 6 is synchronously driven to rotate by the driving motor 5 to dredge the blocked powder. In this embodiment, a plurality of dredging members 6a are uniformly arranged on the dredging roller 6, and the dredging members 6a are made of hard materials. The dredging members 6a can be steel bars, which are welded to the intercommunication roller 6. When the dredging roller 6 rotates, the blocked powder above can be dug and dredged by the dredging members 6a.

[0029] Specifically, one end of the feeding screw 4 is connected to a first transmission shaft 7 arranged on the mounting frame 1. The first transmission shaft 7 is installed on the mounting frame 1 through a mounting seat 13, and the other end of the first transmission shaft 7 is connected to the driving motor 5. One end of the dredging roller 6 is connected to a second transmission shaft 8, and the first transmission shaft 7 and the second transmission shaft 8 are connected by a conveyor belt 9 or a transmission chain to rotate synchronously. In the present utility model, the first transmission shaft 7 and the second transmission shaft 9 are connected by a conveyor belt 9 and driven by a driving motor 5 to realize the synchronous rotation of the feeding screw 4 and the dredging roller 6. This not only ensures the synchronism of the two during operation, dredges the powder in real time while feeding to prevent blockage, but also the dredging roller 6 does not require a separate power drive, reducing the power cost. At the same time, a speed reducer 12 is provided on the driving motor 5, and the output end of the speed reducer 12 is connected to the first transmission shaft 7, and the feeding speed can be adjusted according to the feeding requirements.

[0030] Furthermore, transmission wheels 10 are provided on both the first transmission shaft 7 and the second transmission shaft 8, and a plurality of mounting grooves are provided on the transmission wheels 10, and the conveyor belt 9 is arranged in the mounting grooves. Arranging a plurality of conveyor belts 9 can improve the rotation stability of the dredging roller 6. When one conveyor belt 9 is damaged, the transmission roller 6 will not stop working. In this embodiment, the conveyor belt 9 is arranged in 3 pieces.

[0031] In this embodiment, a mounting member 11 is provided at the lower end of the hopper 3 and communicated with the feeding channel 2, and a mounting hole 11a is vertically penetrated corresponding to the outlet of the hopper 3 on the mounting member 11, and the dredging roller 6 is rotatably arranged in the mounting hole 11a. The upper end of the dredging roller 6 is higher than the upper surface of the mounting member 11. Since the mounting member 11 is fixedly connected to the lower end of the hopper 3, and the lower end aperture of the hopper 3 is the smallest and is the most common blockage position, the higher setting position of the dredging roller 6 can further improve the dredging effect.

[0032] The working principle of the present utility model is as follows:

[0033] Turn on the drive motor 5, pour the material into the hopper 3, the drive motor 5 drives the first transmission shaft 7 to rotate, and at the same time the conveyor belt 9 drives the second transmission shaft 8 to rotate, thereby driving the feeding screw 4 and the dredging roller 6 to rotate simultaneously. The feeding screw 4 completes the feeding of the powder material entering from the hopper 3. The rotation of the dredging roller 6, through the dredging member 6a, completes the dredging of the powder material above to prevent the powder material from being blocked.

[0034] According to the disclosure and teaching of the above specification, those skilled in the art to which the present utility model pertains can also make changes and modifications to the above embodiments. Therefore, the present utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present utility model should also fall within the protection scope of the claims of the present utility model. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present utility model.
