Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, specifically a feeding device for fertilizer production. Background Technology

[0002] In fertilizer processing, fertilizer needs to be transported into the process through a feeding device. However, some fertilizer feeding devices do not have a drying function, while some fertilizers that need to be dried need to be fed into a drying device for drying during processing, which makes the process complicated.

[0003] To address this issue, Chinese patent CN205188159U describes an automatic feeding fertilizer production device that sprays amino acids in a rotating mist, resulting in good spray uniformity, thorough reaction with liquid ammonia, and good drying effect. While this method achieves a drying effect, it is not integrated into the conveyor line; the material is still fed into the granulation tower via a feeding track, making it relatively inconvenient.

[0004] In order to achieve the drying effect of fertilizer after passing through the feeding device, improve drying efficiency, and complete the drying process before the fertilizer enters the next step, a feeding device for fertilizer production is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a feeding device for fertilizer production, which solves the problem that existing feeding devices lack a device for drying fertilizer, thus making subsequent processing of fertilizer inconvenient.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for fertilizer production, comprising a device frame, on which a first feeding structure and a second feeding structure are respectively installed, and a driving structure connects the first feeding structure and the second feeding structure. The first feeding structure comprises a feeding component and a feeding structure. A hot air blowing structure is provided on the device frame, and the hot air blowing structure is connected to the first feeding structure through a vent pipe. The feeding component includes a first conveying outer plate installed at the upper end of the device frame, and an arc-shaped grid plate is installed inside the first conveying outer plate. The surface of the grid plate has through holes, and a cavity is formed between the arc-shaped grid plate and the first conveying outer plate. The upper surface of the first conveying outer plate is also provided with an air outlet pipe, and the lower surface of the first conveying outer plate is provided with a connection opening. The hot air assembly includes a centrifugal fan installed on the device frame. A heating plate is bolted to the upper end of the centrifugal fan, and an air pipe is connected to the upper end of the heating plate. The air pipe is inserted into the cavity through the connection opening. A first feeding shaft is installed inside the first conveying outer plate and connected by a connector. The surface of the first feeding shaft is provided with a spiral feeding plate, and a crushing rod passes through the surface of the spiral feeding plate.

[0007] Furthermore, the feeding structure includes a feeding hopper installed on the bottom surface of the first conveying outer plate. A first reduction motor is installed on one side of the feeding hopper via a second mounting plate. The output end of the first reduction motor extends into the feeding hopper and is connected to the inner wall of the feeding hopper. A scraping plate is installed on the surface of its output end.

[0008] Furthermore, the end of the scraper is curved, and the feed hopper is connected to the interior of the first conveying outer plate.

[0009] As a preferred technical solution, the drive structure includes a first mounting plate installed on the upper surface of the first conveying outer plate, a second servo motor connected to the top of the first conveying outer plate, the output end of the second servo motor connected to the first feeding shaft, the second servo motor having dual-axis output, the other shaft being connected to the outer end face of the first mounting plate and having a pulley installed thereon, a pulley installed on the lower side of the outer end face of the first mounting plate, the two sets of pulleys being driven by a chain, and the pulleys being connected to the second feeding structure.

A discharge plate is installed on the lower surface of the second conveying outer plate.

[0011] As a preferred technical solution, a protective plate is installed on the outer end face of the first mounting plate, and the chain and pulley are wrapped by the protective plate.

[0012] Furthermore, the first conveyor outer plate and the first feeding shaft are both bolted together by multiple connecting plates.

[0013] As a preferred technical solution, the scraping plate has an opening on its surface, and connecting bodies are installed at equal intervals inside the opening.

[0014] Compared with the prior art, the present invention provides a feeding device for fertilizer production, which has the following beneficial effects:

[0015] 1. When the fertilizer enters the feeding structure through the feeding structure, the centrifugal fan heats the outside air through the heating plate and enters the cavity between the first conveying outer plate and the arc-shaped grid plate through the air pipe. The air then enters the first conveying outer plate through the through holes on the surface of the grid plate, thereby drying the fertilizer. The humid air is then discharged through the air outlet pipe. During the drying process, the rotation of the spiral feeding plate drives the crushing rod to rotate, thereby stirring the fertilizer and breaking up any fertilizer that is stuck together. This further improves the drying efficiency and solves the problem that the existing feeding device does not have a drying device, which makes it inconvenient for the fertilizer to enter the next process and affects the fertilizer processing.

Detailed Implementation

[0029] 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.

[0030] Example

[0031] Please see Figure 1-12 This utility model provides the following technical solution: a feeding device for fertilizer production, including a device frame 1, on which a first feeding structure and a second feeding structure are respectively installed, and a driving structure connects the first feeding structure and the second feeding structure. The first feeding structure includes a feeding component and a feeding structure. A hot air blowing structure is provided on the device frame 1, and the hot air blowing structure is connected to the first feeding structure through a vent pipe 8. The feeding component includes a first conveying outer plate 2 installed on the upper end of the device frame 1, and an arc-shaped grid plate 24 is installed inside the first conveying outer plate 2. The surface of the arc-shaped grid plate 24 has through holes, and its arc... A cavity is formed between the grid plate 24 and the first conveying outer plate 2. The upper end of the first conveying outer plate 2 is also provided with an air outlet pipe 3. The lower surface of the first conveying outer plate 2 is provided with a connection opening 14. The hot air assembly includes a centrifugal fan 6 installed on the device frame 1. A heating plate 7 is bolted to the upper end of the centrifugal fan 6. An air vent pipe 8 is connected to the upper end of the heating plate 7. The air vent pipe 8 is inserted into the cavity through the connection opening 14. A first feeding shaft 15 connected by a connector 17 is installed inside the first conveying outer plate 2. A spiral feeding plate 16 is provided on the surface of the first feeding shaft 15, and a crushing rod 22 passes through the surface of the spiral feeding plate 16.

[0032] In this implementation scheme, the specific working principle is as follows: The user feeds fertilizer into the feeding assembly (i.e., into the first feeding structure) through the feeding structure. At this time, the centrifugal fan 6 is started. The centrifugal fan 6 draws external air through the heating plate 7 and then through the air pipe 8 into the cavity between the first conveying outer plate 2 and the arc-shaped grid plate 24. The air then enters the first conveying outer plate 2 through the through holes on the surface of the arc-shaped grid plate 24, thereby drying the fertilizer located in the first conveying outer plate 2. The fertilizer is then discharged from the air outlet pipe 3. In order to increase the drying efficiency, when the first feeding shaft 15 is rotated by the drive structure, it further drives... The rotating spiral feed plate 16 causes the crushing rod 22 to rotate, thereby stirring the fertilizer and breaking up any clumps of fertilizer, thus further accelerating the drying process. The fertilizer then enters the second feeding structure through the spiral feed plate 16 and proceeds to the next process. Through the above structural design, this device solves the problem of existing feeding devices lacking a drying function. Furthermore, this device ensures that the fertilizer is dried within the device before entering the next process, simplifying the process and making it more convenient. The fertilizer can be dried immediately after feeding, making subsequent processing more convenient.

[0033] Based on the above, please refer to the following for details. Figure 1 , Figure 9 , Figure 11 As can be seen, the feeding structure includes a feeding hopper 4 installed on the bottom surface of the first conveying outer plate 2. A first reduction motor 5 is installed on one side of the feeding hopper 4 via a second mounting plate 18. The output end of the first reduction motor 5 extends into the feeding hopper 4 and is connected to the inner wall of the feeding hopper 4. A scraper 19 is installed on the surface of its output end. When fertilizer is poured into the feeding hopper 4, in order to prevent adhesion and blockage, the first reduction motor 5 is started to drive the scraper 19 to rotate, thereby preventing the fertilizer from sticking and blocking.

[0034] To prevent fertilizer granules from sticking together, please refer to the following: Figure 12 As can be seen, the end of the scraper 19 is curved, and the feed funnel 4 is connected to the inside of the first conveying outer plate 2. The scraper 19 has an opening on its surface, and connectors 25 are installed at equal intervals in the opening. There is a gap between the connectors 25 of adjacent groups, which prevents the fertilizer from sticking together during the fertilizer mixing process.

[0035] For details on the driving structure, please refer to [link / reference]. Figure 1 , Figure 2 , Figure 10As can be seen, the drive structure includes a first mounting plate 10 installed on the upper surface of the first conveying outer plate 2. A second servo motor 9 is connected to the top of the first conveying outer plate 2. The output end of the second servo motor 9 is connected to the first feeding shaft 15. The second servo motor 9 has a dual-axis output. Its other shaft is connected to the outer end face of the first mounting plate 10 and a pulley 12 is installed thereon. The pulley 12 is installed on the lower side of the outer end face of the first mounting plate 10. The two sets of pulleys 12 are driven by a chain 11. The pulleys 12 are connected to the second feeding structure.

[0036] Based on the above, the details of its second feeding structure can be found in other articles. Figure 7 , Figure 8 As can be seen, the second feeding structure includes a second conveying outer plate 13 installed on the device frame 1. The second conveying outer plate 13 is connected to the first conveying outer plate 2 through the feed inlet 20 installed on the upper surface of the second conveying outer plate 13. A second feeding shaft 21 is provided inside the second conveying outer plate 13. The second feeding shaft 21 is connected to the output end of the second servo motor 9. A spiral feeding plate 16 is provided on the surface of the second feeding shaft 21. A crushing rod 22 is installed on the surface of the spiral feeding plate 16. A discharge plate 23 is installed on the lower surface of the second conveying outer plate 13.

[0037] To prevent dust from damaging the chain 11, a protective plate is installed on the outer end face of the first mounting plate 10, and the chain 11 and pulley 12 are wrapped by the protective plate.

[0038] To facilitate the manufacture of this device, it is produced using an assembly method; details can be found in [reference needed]. Figure 1 , Figure 4 , Figure 5 As can be seen, the first conveying outer plate 2 and the first feeding shaft 15 are both bolted together by multiple connecting plates, since the first feeding shaft 15 is connected by connecting piece 17.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
