Description

Technical Field

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

[0002] Compound fertilizer is a chemical fertilizer containing two or more nutrients, typically including nitrogen, phosphorus, and potassium as its main components. The main processes in compound fertilizer production include feeding, granulation, drying, cooling, screening, coating, and packaging. Materials are first fed into a hopper for storage, and then conveyed to the next process step via a conveyor belt. Since feeding is the initial step in compound fertilizer production, and the production process is continuous, the continuity and stability of feeding have a significant impact on the entire production process.

[0003] Currently, most compound fertilizer production processes use hoppers for direct feeding. However, due to the large capacity and depth of these hoppers, and the significant drop, materials with larger particles and higher mesh sizes are prone to spillage or run off the conveyor belt due to the strong impact force. Furthermore, the large feed volume and the hopper's top-heavy design can cause material to accumulate within the hopper, potentially leading to uneven feeding, interruptions, or hollow material, thus affecting smooth production. Therefore, this invention provides a feeding buffer device for compound fertilizer to address the aforementioned problems. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] Therefore, the purpose of this utility model is to provide a feeding buffer device for compound fertilizer, so as to solve the problems mentioned in the background art that the existing compound fertilizer production process mostly uses a feeding hopper for direct feeding, which has the problems that the material is easy to spill out of the feeding hopper or rush out of the conveyor belt, and may cause uneven feeding, material breakage or hollow material, thereby affecting the smooth operation of production.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a compound fertilizer feeding buffer device, comprising a feeding hopper, an inner side of which has a downward converging guide slope, a conveying cylinder horizontally mounted on one side of the bottom of the feeding hopper, an inlet at the top of the conveying cylinder corresponding to the bottom converging point of the guide slope, a spiral push rod driven by a servo motor rotating along the length of the inner side of the conveying cylinder, a valve plate adjustable for the size of the inlet opening on one side of the bottom of the feeding hopper, a material distribution chamber plate connected to the bottom of the output end of the conveying cylinder, and vibration components on both sides of the feeding hopper.

[0007] As a preferred embodiment of the compound fertilizer feeding buffer device described in this utility model, the bottom side of the feeding hopper is further provided with a limiting groove that matches the valve plate, the outer end of the valve plate is provided with a fixing ear, and the outer side of the feeding hopper is further provided with an electric push rod whose output end is connected to the fixing ear and drives the valve plate to move left and right.

[0008] As a preferred embodiment of the compound fertilizer feeding buffer device described in this utility model, the vibration component includes support ears fixed to both sides of the outer wall of the feeding hopper, multiple springs vertically connected to the bottom of the support ears, and a vibration motor disposed on the upper part of the support ears.

[0009] As a preferred embodiment of the compound fertilizer feeding buffer device described in this utility model, the bottom of the output end of the conveying cylinder is also provided with a discharge nozzle that is connected to the inclined end of the material distribution chamber plate. The material distribution chamber plate has a structure that is small at the top and wide and flat at the bottom. The bottom inner side of the material distribution chamber plate has a material distribution slope that is slightly inclined to both sides along the central axis.

[0010] As a preferred embodiment of the compound fertilizer feeding buffer device described in this utility model, the top side of the feeding hopper has a feeding port, and the top side of the inner side of the feeding hopper is also provided with a material level sensor, which is located above the feeding port.

[0011] As a preferred embodiment of the compound fertilizer feeding buffer device described in this utility model, a transparent window is also provided on one side of the feeding hopper.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When feeding compound fertilizer, the vibration component drives the feeding hopper to form a continuous high-frequency micro-amplitude vibration, thereby effectively preventing the material deposited in the hopper from accumulating, causing poor feeding flow, and producing hollow material during the output operation. This facilitates the smooth entry of material into the conveying cylinder and final feeding. At the same time, the conveying cylinder can push the material evenly and quantitatively to the distribution chamber plate through the uniformly rotating spiral pusher. Finally, the material particles entering the distribution chamber plate will automatically disperse under the natural guidance of the inclined surface and the combined effect of vibration, and will be evenly discharged through the wide and flat bottom outlet. This effectively reduces the feeding speed of the material and the spillage problem caused by overly concentrated output, ensuring feeding stability and feeding efficiency.

Detailed Implementation

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Secondly, this utility model is described in detail with reference to the schematic diagrams.

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0021] Figures 1-4 The diagram shown is a complete structural schematic of a compound fertilizer feeding buffer device according to this utility model. Please refer to [link / reference]. Figures 1-4 This embodiment of a compound fertilizer feeding buffer device includes a feeding hopper 100, with a downward converging guide slope 110 on the inner side of the feeding hopper 100. A conveying cylinder 200 is horizontally installed on one side of the bottom of the feeding hopper 100. The top of the conveying cylinder 200 has an inlet 220 corresponding to the bottom converging point of the guide slope 110. The inner side of the conveying cylinder 200 has a spiral push rod 210 driven to rotate by a servo motor 240 along its length. A valve plate 300 is provided on one side of the bottom of the feeding hopper 100 to adjust the opening size of the inlet 220. A material distribution chamber plate 500 is connected to the bottom of the output end of the conveying cylinder 200. Vibration components 400 are also provided on both sides of the feeding hopper 100.

[0022] The bottom side of the feeding hopper 100 also has a limiting groove 120 that matches the valve plate 300. The outer end of the valve plate 300 has a fixing ear 310. The outer side of the feeding hopper 100 is also provided with an electric push rod 320 whose output end is connected to the fixing ear 310 and drives the valve plate 300 to move left and right. It can be understood that by driving the valve plate 300 to move left and right through the electric push rod 320, the opening and closing size of the feed inlet 220 is adjusted, thereby adjusting the unit amount of fertilizer entering the conveying cylinder 200 through the feed inlet 220 and the unit output amount of feeding. The vibration assembly 400 includes support ears 410 fixed to both sides of the outer wall of the feeding hopper 100, multiple springs 420 vertically connected to the bottom of the support ears 410, and a vibration motor 430 set on the upper part of the support ears 410. It should be noted that in actual installation, the springs 420 are mounted on a fixed platform, so that the feeding hopper 100 is in an elastic suspended state, which is conducive to the implementation of vibration. The bottom of the output end of the conveyor cylinder 200 also has a discharge nozzle 230 that communicates with the inclined end of the fabric packing plate 500. The fabric packing plate 500 has a structure that is small at the top and wide and flat at the bottom. The bottom inner side of the fabric packing plate 500 has a material-equalizing ramp 510 that is slightly inclined to both sides along the central axis. It can be understood that when the conveyor cylinder 200 introduces material into the fabric packing plate 500 through the discharge nozzle 230, the material particles will automatically disperse under the combined effect of the natural flow of the inclined surface and vibration, and be discharged through the wide and flat output port at the bottom of the fabric packing plate 500. Specifically, in this embodiment, during feeding, the vibration component 400 drives the feeding hopper 100 to generate continuous high-frequency micro-amplitude vibration, thereby effectively preventing the material deposited in the hopper from accumulating, causing poor feeding flow, and producing hollow material during the output operation. This facilitates the smooth entry of material into the conveying cylinder 200 and the final feeding. At the same time, the conveying cylinder 200 can push the material evenly and quantitatively to the material distribution chamber 500 through the uniformly rotating spiral push rod 210. Finally, the material particles entering the material distribution chamber 500 will automatically disperse under the natural guidance of the inclined surface and the combined effect of vibration, and will be evenly discharged through the wide and flat bottom outlet. This effectively reduces the feeding speed of the material and the spillage problem caused by overly concentrated output, ensuring feeding stability and feeding efficiency.

[0023] Preferably, the top side of the feeding hopper 100 has a feed inlet 130, and a level sensor 600 is also installed on the top side of the inner side of the feeding hopper 100, with the level sensor 600 located above the feed inlet 220. It can be understood that the level sensor 600 can be a laser rangefinder or an ultrasonic probe, etc., mainly to detect the real-time distance between the top surface of the material in the feeding hopper 100 and the top of the inner side of the hopper. For example, when the distance is greater than the value set by the control system, the system will automatically determine that the material in the hopper is insufficient, and then can automatically alarm or automatically add material, further ensuring the normal operation of the device.

[0024] As a preferred option, a transparent window 140 is further provided on one side of the feeding hopper 100. During actual operation, the staff can directly observe the actual amount of material remaining in the feeding hopper 100 through the transparent window 140, making it more user-friendly.

[0025] In summary, the compound fertilizer feeding buffer device of this embodiment, during feeding, the vibration component 400 drives the feeding hopper 100 to form continuous high-frequency micro-amplitude vibration, thereby effectively preventing the material deposited in the hopper from accumulating, causing poor feeding flow, and producing hollow material during the output operation. This facilitates the smooth entry of material into the conveying cylinder 200 and the final feeding. At the same time, the conveying cylinder 200 can push the material evenly and quantitatively to the distribution chamber 500 through the uniformly rotating spiral push rod 210. Finally, the material particles entering the distribution chamber 500 will automatically disperse under the natural guidance of the inclined surface and the combined effect of vibration, and will be evenly discharged through the wide and flat bottom outlet, effectively reducing the feeding speed of the material and the spillage problem caused by overly concentrated output.

[0026] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
