Description

Technical Field

[0001] This utility model relates to the field of compound fertilizer production technology, and specifically discloses an automatic compound fertilizer packaging machine. Background Technology

[0002] Compound fertilizers are chemical fertilizers containing two or more nutrients. They have advantages such as high nutrient content, fewer byproducts, and good physical properties, playing a vital role in balanced fertilization, improving fertilizer utilization, and promoting high and stable crop yields. However, they also have some drawbacks. For example, their nutrient ratios are always fixed, while different soils and crops require different types, quantities, and ratios of nutrients. Therefore, it is best to conduct soil testing before use to understand the soil texture and nutrient status. Additionally, it is important to use them in combination with single-nutrient fertilizers to achieve better results.

[0003] Chinese patent CN216861858U discloses an automatic compound fertilizer packaging machine, including a base plate. At least two columns are fixedly connected to the upper surface of the base plate. At least two columns are fixedly connected to a fixing plate for installing a hopper at their ends away from the base plate. A connecting shaft is rotatably connected inside the hopper. At least four stirring blades for stirring the compound fertilizer inside the hopper are fixedly connected to the outer surface of the connecting shaft. By setting stirring blades and a connecting frame on the outer surface of the connecting shaft and opening a guide trough inside the hopper, it is not only convenient for users to take an equal amount of compound fertilizer for filling by rotating the guide cylinder, but also convenient for users to stir the compound fertilizer inside the hopper with the stirring blades on the outer surface of the connecting shaft while rotating the guide cylinder, so that it can be mixed evenly for filling. This achieves the purpose of convenient quantitative filling and uniform discharge.

[0004] The aforementioned document discloses an automatic compound fertilizer packaging machine that fails to secure the packaging bags during use, causing the bags to easily tip over during the filling process. Therefore, an automatic compound fertilizer packaging machine is needed to solve this problem. Utility Model Content

Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0023] Please see Figure 1-5 An automatic compound fertilizer packaging machine includes a hopper 1. A base plate 2 is fixedly connected to the lower end of the hopper 1 via a support leg 3. An electronic scale 16 is installed on the upper end of the base plate 2. A discharge port 4 with a solenoid valve installed on the outer wall is provided at the lower end of the hopper 1. A fixing mechanism is provided on the outer wall of the discharge port 4. The fixing mechanism includes a fixing plate 5 fixedly connected to the outer wall of the discharge port 4. Multiple sliding grooves 6 are opened through the outer wall of the fixing plate 5. Sliding blocks 7 are slidably connected to the inner walls of the multiple sliding grooves 6. Inner support plates 8 are fixedly connected to the lower end of the multiple sliding blocks 7. A connecting shaft 9 is fixedly connected to the upper end of the multiple sliding blocks 7. A turntable 10 located above the fixing plate 5 is rotatably connected to the outer wall of the discharge port 4 via a bearing. Multiple arc-shaped grooves 11 slidably connected to the connecting shaft 9 are opened through the outer wall of the turntable 10. A drive mechanism for driving the turntable 10 to rotate is provided at the lower end of the hopper 1.

[0024] In this embodiment: the packaging bag is placed on the electronic scale 16, and the inlet of the packaging bag is fitted onto the outlet 4. The turntable 10 is rotated, and the turntable 10 drives multiple sliders 7 to slide outward synchronously along the slide groove 6 through the arc groove 11 and the connecting shaft 9, thereby driving multiple inner support plates 8 to slide outward synchronously, opening and fixing the packaging bag to prevent it from tipping over during filling. The solenoid valve on the outer wall of the outlet 4 is opened, and the fertilizer in the hopper 1 enters the packaging bag through the outlet 4. When the electronic scale 16 detects that the fertilizer in the packaging bag has reached the set amount, it transmits a signal to the controller. The controller controls the solenoid valve to close the outlet 4. The packaging bag can be removed by rotating the turntable 10 in the opposite direction. This utility model can fix packaging bags of different specifications and has strong practicality.

[0025] As a technical optimization of this utility model, the driving mechanism includes a servo motor 14 installed on the lower end face of the hopper 1, a gear 15 fixedly connected to the output end of the servo motor 14, and a gear ring 13 that meshes with the gear 15 fixedly connected to the outer wall of the turntable 10.

[0026] In this embodiment: the servo motor 14 is started, which in turn drives the gear 15 to rotate. The gear 15 further drives the gear ring 13 to rotate, which in turn drives the turntable 10 to rotate, causing the inner support plate 8 to move inward or outward.

[0027] As a technical optimization of this utility model, an installation plate 17 is fixedly connected to the upper end face of the hopper 1, and a drive motor 18 is installed on the upper end face of the installation plate 17. The output end of the drive motor 18 extends into the interior of the hopper 1 and is fixedly connected to a stirring rod 19.

[0028] In this embodiment: the drive motor 18 is started, and the drive motor 18 drives the stirring rod 19 to rotate, stirring the fertilizer in the hopper 1 to prevent the fertilizer from clogging during the discharge process.

[0029] As a technical optimization of this utility model, a tapered rod 12 is fixedly connected to the outer wall of the inner support plate 8.

[0030] In this embodiment, the tapered rod 12 is fixedly connected to the outer wall of the inner support plate 8 to facilitate further fixation of the packaging bag.

[0031] As a technical optimization of this utility model, the slider 7 is in the shape of an I-beam.

[0032] In this embodiment: by setting the slider 7 to an I-shape, the slider 7 is prevented from coming off the groove 6.

[0033] As a technical optimization of this utility model, a controller is provided on the outer wall of one of the support legs 3, and the servo motor 14, electronic scale 16 and drive motor 18 are all electrically connected to the controller.

[0034] In this embodiment, the controller facilitates the normal operation of the servo motor 14, the electronic scale 16, and the drive motor 18.

[0035] The working principle and usage process of this utility model are as follows: First, place the packaging bag on the electronic scale 16 and align the bag's inlet with the outlet 4. Then, start the servo motor 14, which drives the gear 15 to rotate. The gear 15 further drives the gear ring 13 to rotate, which in turn drives the turntable 10 to rotate. The turntable 10, through the arc groove 11 and connecting shaft 9, drives multiple sliders 7 to slide outward synchronously along the slide groove 6, thereby driving multiple inner support plates 8 to slide outward synchronously, opening the packaging bag. A conical rod 12 is then inserted into the packaging bag to fix it in place, preventing the bag from tipping over during filling. Next, the solenoid valve on the outer wall of the discharge port 4 is opened by the controller, and the fertilizer in the hopper 1 enters the packaging bag through the discharge port 4. When the electronic scale 16 detects that the fertilizer in the packaging bag has reached the set amount, it transmits a signal to the controller. The controller controls the solenoid valve to close the discharge port 4, and then the packaging bag can be removed by rotating the turntable 10 in the reverse direction by the servo motor 14. During filling, the stirring rod 19 is driven by the drive motor 18 to rotate and stir the fertilizer in the hopper 1 to prevent the fertilizer from clogging during the discharge process. This utility model can fix packaging bags of different specifications and has strong practicality.
