Abstract
Description
Technical Field
[0001] This utility model relates to the field of fertilizer production technology, specifically to a quantitative packaging and weighing metering structure for solid organic fertilizer. Background Technology
[0002] Organic fertilizers, also known as "farmyard manure," refer to any fertilizer made from organic matter (compounds containing carbon). These include human excrement, manure, compost, green manure, oilseed cake, and biogas slurry. They are characterized by their variety, wide availability, and long-lasting effects.
[0003] When packaging organic fertilizers, they are generally packaged in quantitative quantities using weighing and metering equipment. However, organic fertilizers are often packaged by mixing various raw materials together to form compound fertilizers, thereby enhancing their effectiveness. Therefore, during packaging, multiple feeding structures are often set up to feed different amounts of different fertilizers into the hopper of the metering structure. Once the weight reaches the standard, feeding stops and the valve at the bottom of the hopper opens to transport the mixed fertilizer into the packaging bag. However, this method cannot mix the various fertilizers evenly, which will result in the fertilizer not exerting the actual effect of the compound fertilizer when used, and may even affect crop growth. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a quantitative packaging and weighing structure for solid organic fertilizers. This solves the problem that current packaging and weighing equipment cannot mix materials, which may result in the fertilizer not achieving its actual effect when used as a mixed fertilizer, and may even affect crop growth.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a quantitative packaging and weighing structure for solid organic fertilizer, comprising a horizontally arranged platform plate and a mixing mechanism;

A shaft hole is vertically opened through the center of the upper surface of the first device plate and the second device plate. A mixing shaft is vertically rotatably connected inside the two shaft holes. Multiple mixing blades are fixedly connected to the surface of the mixing shaft and located on the upper part of the upper surface of the first device plate and the second device plate.

Detailed Implementation
[0018] 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.
[0019] Please see Figure 1-3 This utility model provides a technical solution: a quantitative packaging and weighing structure for solid organic fertilizer, including a horizontally arranged platform plate 1 and a mixing mechanism;
[0020] Multiple corners of the lower surface of the platform plate 1 are vertically fixed with support legs 18. A metering hopper 4 is provided in the middle of the platform plate 1, and a mixing mechanism is provided above the metering hopper 4.
[0021] The mixing mechanism includes a mixing cylinder 8 disposed above the metering hopper 4. The top and bottom of the mixing cylinder 8 are respectively fixedly connected to a first device plate 12 and a second device plate 13. The middle part of the upper surface of the first device plate 12 and the middle part of the lower surface of the second device plate 13 are respectively concave and convex to form mutually symmetrical conical surfaces. The center of the upper surface of the first device plate 12 and the second device plate 13 are vertically opened through shaft holes. The mixing shaft 14 is vertically rotatably connected inside the two shaft holes. Multiple mixing blades 15 are fixedly connected to the surface of the mixing shaft 14 and the upper part of the upper surface of the first device plate 12 and the second device plate 13. The middle part of the upper surface of the first device plate 12 and the outer edge of the second device plate 13 are respectively vertically opened through a first discharge port 16 and a second discharge port 17.
[0022] When in use, the device can pre-mix the raw materials of organic fertilizer through the mixing mechanism, and then send them into the metering hopper to prevent uneven mixing of the final finished fertilizer. The mixing shaft 14 rotates continuously during the operation of the device, and the two types of mixing blades 15 on its surface are adapted to the upper surface contours of the first device plate 12 and the second device plate 13, respectively. During the rotation of the mixing shaft 14, the multiple mixing blades 15 can continuously stir and mix the materials in the mixing cylinder 8.
[0023] Since both the first device plate 12 and the second device plate 13 in the mixing mechanism are conical, the material entering the device will first move towards the center along the upper surface contour of the first device plate 12, then fall onto the upper surface of the second device plate 13 through the first discharge port 16 and move towards the outer edge along its upper surface contour, and finally be discharged through the second discharge port 17. The first device plate 12 and the second device plate 13 increase the residence time of the fertilizer in the mixing mechanism, ensuring thorough mixing.
[0024] Multiple crossbars 9 are horizontally fixedly connected to the top of the inner surface of the mixing cylinder 8. Fixed plates 10 are fixedly connected to the inner ends of the multiple crossbars 9. A motor 11 is fixedly connected to the upper surface of the fixed plate 10. The bottom end of the output shaft of the motor 11 rotatably passes through the fixed plate 10 and is fixedly connected to the top of the mixing shaft 14.
[0025] Multiple connecting brackets 7 are fixedly connected to the outer surface of the mixing cylinder 8, and the bottom ends of the multiple connecting brackets 7 are fixedly connected to the upper surface of the platform plate 1.
[0026] The mixing mechanism is mounted on the platform plate 1 via multiple connecting frames 7, and the mixing shaft 14 is driven to rotate by the motor 11.
[0027] A device opening is vertically through the middle of the upper surface of the platform plate 1. Multiple guide posts 2 are vertically fixedly connected to the upper surface of the platform plate 1 and outside the device opening. A connecting ring 3 is vertically slidably connected to the outer surface of the multiple guide posts 2. A metering hopper 4 is fixedly connected to the inside of the connecting ring 3. Multiple sensors 5 are arranged between the lower surface of the connecting ring 3 and the upper surface of the platform plate 1.
[0028] A solenoid valve 6 is installed at the bottom of the discharge port of the metering hopper 4.
[0029] The metering hopper 4 slides vertically through the connecting ring 3 and the guide column 2, and is supported by multiple sensors 5. After the fertilizer is poured into the metering hopper 4, the metering hopper 4 will move downward under the action of its weight. The multiple sensors 5 can measure its overall weight based on the actual height of the descent. This structure is an existing weighing and metering technology, which will not be described in detail here.
[0030] Once the weight reaches the specified value, the solenoid valve 6 will open and pour out the fertilizer from the metering hopper 4.
[0031] The central axes of the metering hopper 4 and the mixing cylinder 8 are located on the same straight line.
[0032] The fact that the central axes of both are on the same straight line ensures that the fertilizer discharged from the bottom of the mixing cylinder 8 will not spill onto the outside of the metering hopper 4, thus avoiding waste.
[0033] When in use, the device can pre-mix the raw materials of organic fertilizer through the mixing mechanism, and then send them into the metering hopper to prevent uneven mixing of the final finished fertilizer. The mixing shaft 14 rotates continuously during the operation of the device, and the two types of mixing blades 15 on its surface are adapted to the upper surface contours of the first device plate 12 and the second device plate 13, respectively. During the rotation of the mixing shaft 14, the multiple mixing blades 15 can continuously stir and mix the materials in the mixing cylinder 8.
