Description

Technical Field

[0001] This utility model relates to the technical field of compound fertilizer production equipment, and in particular to a proportioning device for compound fertilizer production. Background Technology

[0002] Compound fertilizer is a fertilizer made by mixing various nutrients in a certain proportion according to the needs of crops. It can meet the needs of crops and increase crop yield. In the production process of compound fertilizer, the accuracy of the raw material ratio directly affects the quality of compound fertilizer.

[0003] The powdered raw materials used in compound fertilizers are prone to clumping due to factors such as humidity and pressure in the storage environment. The weight of these clumps differs significantly from that of the same volume of powdered raw materials, causing large fluctuations in the weighing results. This makes it difficult to accurately control the proportion of each raw material, thereby affecting the product quality and performance of the compound fertilizer. To address this issue, we propose a proportioning device for compound fertilizer production. Utility Model Content

[0004] The purpose of this invention is to provide a proportioning device for compound fertilizer production to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0011] In a further embodiment, the upper surface of the storage box and the upper surface of the feeding funnel are both hinged to a dust cover, and the outer surface of the outer shell is hinged to an observation plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device uses a vibrating motor to drive the connecting inclined plate and filter screen to vibrate. With the inclined connecting inclined plate, it can intercept agglomerated raw materials on the filter screen and make them slide into the storage box, avoiding interference from agglomerated raw materials and ensuring weighing accuracy. A servo motor drives the spiral blades to rotate and transport the raw materials. With the help of a weighing sensor to detect the weight of the raw materials in the weighing pan in real time, the controller can immediately stop the servo motor when the weight reaches the set value, thereby accurately controlling the amount of raw materials transported and ensuring that the proportion of each raw material meets the production requirements.

[0021] 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.

[0022] Please see Figure 1-4In this utility model, a compound fertilizer production proportioning device includes a housing 1. The inner wall of the housing 1 is provided with a connecting inclined plate 6. A vibrating motor 7 is fixedly connected to the bottom surface of the connecting inclined plate 6. A filter screen 8 is fixedly connected to the upper surface of the connecting inclined plate 6. A collecting funnel 9 is fixedly connected to the inner side wall of the housing 1. A feeding pipe 10 is fixedly connected to the bottom surface of the collecting funnel 9. A bearing 11 is embedded in the inner side wall of the feeding pipe 10. A spiral blade 12 is fixedly connected to the inner ring of the bearing 11. A servo motor 13 is fixedly connected to the back of the feeding pipe 10. The output end of the servo motor 13 is fixedly connected to the back of the spiral blade 12. A weighing sensor 14 is fixedly connected to the inner bottom wall of the housing 1. A weighing pan 15 is provided on the upper surface of the weighing sensor 14. A controller 19 is fixedly connected to the inner bottom wall of the housing 1. The controller 19 is electrically connected to the weighing sensor 14 and the servo motor 13 via wires, enabling [the device to] form [a certain configuration]. This system forms a closed-loop control system. During use, the operator can preset the required raw material ratio and weight parameters through the controller 19. During equipment operation, the weighing sensor 14 detects the weight of the raw material in the weighing pan 15 in real time and continuously transmits the weight signal to the controller 19. After receiving the signal, the controller 19 compares it with the preset weight parameters. When the weight of the raw material in the weighing pan 15 reaches the set value, it immediately sends a stop signal to the servo motor 13 to stop the servo motor 13 from running, thereby stopping the spiral blades 12 from conveying raw materials. This accurately controls the amount of raw material falling into the weighing pan 15, ensuring that the compound fertilizer raw material ratio meets the preset requirements. The vibration motor 7 drives the connecting inclined plate 6 and the filter screen 8 to vibrate, which can improve the screening efficiency of the filter screen 8. By designing the filter screen 8 as an inclined plane, it can discharge the clumps of raw materials and avoid clogging the filter screen 8.

[0023] Two connecting plates 2 are fixedly connected to the inner wall of the outer casing 1. Two sliding rods 3 are fixedly connected to the upper surface of each connecting plate 2. A connecting cylinder 4 is slidably connected to the outer surface of each sliding rod 3. An elastic element 5 is fixedly connected to the bottom surface of each connecting cylinder 4. The bottom surfaces of every two elastic elements 5 are fixedly connected to the upper surface of each connecting plate 2. The upper surface of each connecting cylinder 4 is fixedly connected to the bottom surface of the connecting inclined plate 6. The elastic element 5 is a helical spring. Through the cooperation of the sliding rods 3, the connecting cylinders 4 and the elastic element 5, the vibration of the connecting inclined plate 6 can be limited, so that the connecting inclined plate 6 vibrates stably up and down.

[0024] A feed funnel 16 is fixedly connected to the upper surface of the outer shell 1, a baffle 22 is fixedly connected to the upper surface of the connecting inclined plate 6, a discharge inclined plate 17 is fixedly connected to the inner side wall of the outer shell 1, and a storage box 18 is fixedly connected to the outer surface of the outer shell 1. The upper surface of the storage box 18 and the upper surface of the feed funnel 16 are both connected to a dust cover 20 by hinges. An observation plate 21 is connected to the outer surface of the outer shell 1 by hinges. The inclination of the discharge inclined plate 17 is higher than that of the connecting inclined plate 6, which allows the raw material to roll directly into the storage box 18. By setting the feed funnel 16, the raw material can fall accurately onto the filter screen 8.

[0025] The working principle of this utility model is as follows:

[0026] When using this device, the powdered compound fertilizer raw material is placed into the feed funnel 16, allowing the raw material to fall onto the filter screen 8. The vibration motor 7 is turned on to drive the connecting inclined plate 6 and the filter screen 8 to vibrate. With the help of the slide rod 3, the connecting slide cylinder 4, and the elastic element 5, the connecting inclined plate 6 and the filter screen 8 vibrate up and down. The clumps of raw material are intercepted by the filter screen 8 and slide into the discharge inclined plate 17 and the storage box 18. The filtered raw material falls into the collection funnel 9 and the feeding pipe 10. The controller 19 sets the required weight of the raw material, and the servo motor 13 drives the spiral blade 12 to rotate, slowly conveying the raw material into the weighing pan 15. The weighing sensor 14 detects the weight of the weighing pan 15 and the raw material. Once the weight reaches the set value, the servo motor 13 stops immediately, thus obtaining the required amount of raw material for the desired ratio.
