[0002] Blended fertilizer production is a crucial step in compound fertilizer manufacturing, and its core lies in the precise proportioning of various raw materials. In current mainstream production processes, the accuracy of raw material metering directly affects the nutrient uniformity of the finished fertilizer.

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] This application discloses an automatic metering and feeding device for raw materials used in the production of blended fertilizers. (Refer to...) Figure 1 , Figure 2 and Figure 3As shown, an automatic metering and feeding device for raw materials used in the production of blended fertilizer includes a base 1, which comprises a base plate 11 and positioning brackets 12. Two sets of positioning brackets 12 are symmetrically installed on both sides of the upper surface of the base plate 11. The positioning brackets 12 are fixedly connected to the base plate 11. A belt feeding assembly 2 is installed between the two sets of positioning brackets 12.

A side baffle assembly 4, which cooperates with the belt feeding assembly 2, is also fixedly installed at the upper end of the positioning brackets 12. Several measuring bins 5 are evenly installed on the upper surface of the side baffle assembly 4, and the measuring bins 5 are inserted and fixedly connected to the side baffle assembly 4. A weighing sensor is also fixedly installed in each measuring bin 5. The equipment base 1 provides a stable support foundation for the entire device. The belt feeding assembly 2 enables continuous conveying of raw materials. The guide shell 3 accurately guides the raw materials conveyed by the feeding assembly to subsequent processing stages. The side baffle assembly 4 prevents raw materials from scattering during conveying. The measuring bin 5 is used for measuring and storing raw materials. The various components work together to enable the device to efficiently and accurately complete the automatic measurement and feeding of raw materials. The positioning bracket 12 includes a short plate 121, an inclined plate 122, and a long plate 123. The short plate 121 and the long plate 123 are vertically installed at both ends of the inclined plate 122, and both the short plate 121 and the long plate 123 are fixedly connected to the inclined plate 122. The structural design of the positioning bracket 12, with its short plate 121, inclined plate 122, and long plate 123, not only enhances the structural strength of the bracket but also provides suitable space and angle for the installation of the belt feeding assembly 2, allowing the belt feeding assembly 2 to convey raw materials at an angle, which is beneficial to improving feeding efficiency.

[0031] Reference Figure 3As shown, the belt feed assembly 2 includes a bottom roller 21, a middle support plate 22, a conveyor belt 23, and a top roller 24.

The two ends of the conveyor belt 23 are respectively sleeved on the bottom roller 21 and the top roller 24. The top roller 24 is rotatably mounted on the long plate portion 123, and a drive motor 124 for driving the top roller 24 is fixedly mounted on the long plate portion 123. The belt feed assembly 2 achieves continuous material conveying through the cooperation of the bottom roller 21, the middle support plate 22, the conveyor belt 23, and the top roller 24. The drive motor 124 drives the top roller 24 to rotate, thereby driving the conveyor belt 23. The middle support plate 22 supports the conveyor belt 23, ensuring its stability during conveying and improving the reliability of the feed. Several sets of material plates 231 are evenly arranged on the outer surface of the conveyor belt 23, and the material plates 231 are fixedly connected to the conveyor belt 23. The material plates 231 arranged on the outer surface of the conveyor belt 23 can increase the friction between the conveyor belt 23 and the raw material, prevent the raw material from slipping during the conveying process, and also improve the load-bearing capacity of the conveyor belt 23, so that more raw materials can be conveyed stably, further improving the feeding efficiency.

[0032] Reference Figure 3 As shown, the material guide shell 3 includes an inclined bottom shell 31 and a flow guide plate 32. The flow guide plate 32 is symmetrically installed on the upper end face of the inclined bottom shell 31 and is fixedly connected to the inclined bottom shell 31.

The design of the inclined bottom shell 31 and the flow guide plate 32 of the material guide shell 3 can smoothly guide the raw materials conveyed by the conveyor belt 23 to the subsequent processing stage. The flow guide plate 32 can adjust the flow direction of the raw materials to ensure that the raw materials can accurately enter the designated position, thereby improving the accuracy of raw material conveying.

[0033] Reference Figure 4 and Figure 5As shown, the side baffle assembly 4 includes a connecting middle seat 41 and two sets of side baffles 42. The two sets of side baffles 42 are installed on both sides of the connecting middle seat 41 and are fixedly connected to the connecting middle seat 41. The structure of the connecting middle seat 41 and the two sets of side baffles 42 of the side baffle assembly 4 can effectively prevent raw materials from scattering from both sides of the conveyor belt 23 during the conveying process, ensuring a clean production environment, reducing raw material waste, and improving raw material utilization.

The lower end face of the discharge shell 412 is also fixedly installed with an auxiliary inclined plate 413. The positioning slot 411 on the connecting seat 41 facilitates the installation and disassembly of the measuring bin 5. The discharge shell 412 is used to discharge the raw materials in the measuring bin 5. The auxiliary inclined plate 413 can guide the raw materials to flow more smoothly into the conveyor belt 23, improving the efficiency and accuracy of raw material discharge.

[0034] Reference Figure 6 As shown, the measuring hopper 5 includes a flow-gathering shell 51 and a plug-in shell 52 corresponding to the positioning slot 411. The plug-in shell 52 is fixedly installed on the lower end face of the flow-gathering shell 51, and a control valve 521 is installed in the plug-in shell 52. The flow-gathering shell 51 of the measuring hopper 5 can gather the raw materials together, which is convenient for metering and discharge. The cooperation between the plug-in shell 52 and the positioning slot 411 makes the installation of the measuring hopper 5 more stable. The control valve 521 can accurately control the discharge of raw materials, realizing accurate metering and feeding of raw materials.

[0035] The implementation principle of the automatic metering and feeding device for raw materials in the production of blended fertilizers according to this application embodiment is as follows: During the production process, the opening and closing time and opening degree of the control valve 521 can be adjusted as needed to accurately control the discharge amount of raw materials and realize automatic metering of raw materials. At the same time, by installing a weight sensor, such as a weighing sensor of model HX, in the metering hopper 5 and connecting it with a microcontroller of model Arduino Uno, real-time monitoring and precise control of the weight of raw materials can be realized. In actual use, the raw materials are placed into the flow collection shell 51 of the metering hopper 5, and the discharge of raw materials is controlled by the control valve 521 according to production needs. The raw materials are discharged from the discharge shell 412 and flow into the conveyor belt 23 through the auxiliary inclined plate 413. The drive motor 124 is started to drive the top roller 24 to rotate, thereby driving the conveyor belt 23 to operate, and the conveyor plate 231 on the conveyor belt 23 conveys the raw materials upward. When the raw materials are conveyed to the end of the conveyor belt 23, the inclined bottom shell 31 of the guide shell 3 and the guide inclined plate 32 guide the raw materials to the subsequent processing stage.
