Description

Technical Field

[0001] This utility model relates to a fertilizer mixing and stirring device, belonging to the field of fertilizer machinery technology. Background Technology

[0002] Organic fertilizers offer a comprehensive range of nutrients but in low concentrations, while chemical fertilizers provide a single type of nutrient but in high concentrations. Using them in combination provides a more comprehensive and balanced supply of nutrients, meeting the diverse nutrient needs of crops at different growth stages. For example, organic fertilizers have relatively low levels of macronutrients such as nitrogen, phosphorus, and potassium, but are rich in micronutrients and organic matter; while chemical fertilizers such as urea and diammonium phosphate primarily provide macronutrients. Using them in combination can supplement micronutrients and organic matter while providing macronutrients.

[0003] Traditional mixed fertilization methods involve applying chemical fertilizer first, followed by organic fertilizer, or mixing organic and chemical fertilizers in a pre-mixed container. The former requires two separate operations with two separate machines, resulting in low efficiency and increased costs; the latter results in low mixing intensity, which can lead to uneven mixing or segregation, especially with organic fertilizers that tend to clump or chemical fertilizers with significant differences in specific gravity. Furthermore, chemical fertilizers are hygroscopic and can react chemically with damp organic fertilizers, reducing fertilizer effectiveness and corroding the equipment.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] This utility model addresses the shortcomings of the prior art by providing a fertilizer mixing device that can solve the problem of the limited functionality of single equipment and its inability to meet the requirements of compound fertilization, as well as the problem of poor uniformity in the mixing of organic fertilizer and chemical fertilizer.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: A fertilizer mixing device includes an inner hopper and an outer hopper fitted around the inner hopper. The bottom ends of the inner and outer hoppers are connected by a fixed plate. A turntable, a spreading plate, and a gearbox are installed sequentially below the fixed plate. A stirring shaft is installed on the output end of the gearbox. The stirring shaft passes vertically through the spreading plate, the turntable, and the fixed plate. A ring-shaped guide shroud is fixed to the bottom of the turntable. Stirring blades are provided inside the guide shroud and are fixed to the stirring shaft.

[0007] Furthermore, the inner hopper has an opening at the top, and the interior of the inner hopper is an organic fertilizer storage chamber; a chemical fertilizer storage chamber is formed between the inner hopper and the outer hopper.

[0008] Furthermore, the top of the inner hopper and the top of the outer hopper are connected by a ring plate, and a fertilizer inlet is provided on one side of the top of the fertilizer storage chamber.

[0009] Furthermore, both the fixed plate and the turntable are provided with organic fertilizer discharge holes and chemical fertilizer discharge holes. The organic fertilizer discharge holes on the fixed plate are located at the bottom of the organic fertilizer storage chamber, and the chemical fertilizer discharge holes on the fixed plate are located at the bottom of the chemical fertilizer storage chamber.

[0010] Furthermore, the spreading disc is fixedly connected to the stirring shaft.

[0011] Furthermore, both the turntable and the fixed disc are rotatably connected to the stirring shaft.

[0012] Furthermore, the turntable side is hinged to the head of the telescopic rod, and the tail of the telescopic rod is hinged.

[0013] Furthermore, multiple evenly distributed spreading plates are fixedly installed on the upper surface of the spreading disc.

[0014] Furthermore, the input end of the gearbox is connected to the power output shaft of the tractor.

[0015] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: This utility model simultaneously completes all functions of storing, metering, mixing, and spreading organic and chemical fertilizers. It can be directly connected to a tractor and complete compound fertilization in one operation, which greatly improves work efficiency and automation. This invention employs a two-stage mixing process to ensure a forced mixing effect. Inside the guide hood, the falling fertilizer is broken up, cut, and initially mixed by the high-speed rotating stirring blades. The initially mixed fertilizer falls onto the high-speed rotating spreading disc and is thrown out under centrifugal force. The throwing process ensures the final uniform mixing of organic and chemical fertilizers.

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0019] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0020] like Figure 1 and Figure 2 As shown in the figure, this utility model provides a fertilizer mixing device, including an inner hopper 1 with a top opening, an organic fertilizer storage chamber 3 inside the inner hopper 1, an outer hopper 2 sleeved on the outside of the inner hopper 1, and a chemical fertilizer storage chamber 4 formed between the inner hopper 1 and the outer hopper 2.

[0021] The bottom of the inner hopper 1 and the bottom of the outer hopper 2 are connected by a fixed plate 7.

[0022] The top of the inner hopper 1 and the top of the outer hopper 2 are connected by a ring plate 5. A fertilizer inlet 6 is provided on one side of the top of the fertilizer storage chamber 4. The top of the fertilizer storage chamber 4 is sealed by the ring plate 5 to prevent the fertilizer from absorbing moisture, clumping, and leaking.

[0023] Below the fixed disk 7, a turntable 8, a spreading disk 13, and a gearbox 15 are installed in sequence. A stirring shaft 11 is installed on the output end of the gearbox 15. The stirring shaft 11 passes through the spreading disk 13, the turntable 8, and the fixed disk 7 in a vertical direction.

[0024] The spreading disc 13 is fixedly connected to the stirring shaft 11, and the spreading disc 13 rotates at high speed with the stirring shaft 11.

[0025] Both the turntable 8 and the fixed plate 7 are rotatably connected to the stirring shaft 11.

[0026] Both the fixed plate 7 and the turntable 8 are provided with organic fertilizer discharge holes 16 and chemical fertilizer discharge holes 17. The organic fertilizer discharge holes 16 on the fixed plate 7 are located at the bottom of the organic fertilizer storage chamber 3, and the chemical fertilizer discharge holes 17 on the fixed plate 7 are located at the bottom of the chemical fertilizer storage chamber 4.

[0027] The turntable 8 is hinged to the head of the telescopic rod 9, and the tail of the telescopic rod 9 is also hinged. During the extension and retraction process, the telescopic rod 9 drives the turntable 8 to rotate along the stirring shaft 11. When the turntable 8 rotates to a specific position, the organic fertilizer discharge hole 16 and the chemical fertilizer discharge hole 17 on it are aligned vertically with the organic fertilizer discharge hole 16 and the chemical fertilizer discharge hole 17 on the fixed plate 7, and the organic fertilizer and chemical fertilizer fall down.

[0028] The bottom of the turntable 8 is fixedly connected to a ring-shaped guide shroud 10, and the guide shroud 10 is provided with stirring blades 12, which are fixedly connected to the stirring shaft 11. The stirring blades 12 rotate with the stirring shaft 11, and after the organic fertilizer and chemical fertilizer are initially mixed, they enter the spreading disc 13.

[0029] Multiple evenly distributed spreading plates 14 are fixedly installed on the upper surface of the spreading disc 13. The spreading plates 14 rotate with the spreading disc 13 and spread the pre-mixed organic fertilizer and chemical fertilizer through centrifugal force.

[0030] The input end of the gearbox 15 is connected to the power output shaft of the tractor.

[0031] The specific working principle of this utility model is as follows: Independent storage: Organic fertilizers (such as manure and compost) are stored in inner hopper 1; chemical fertilizers (such as granular compound fertilizer and urea) are stored in the chemical fertilizer storage chamber 4 between inner hopper 1 and outer hopper 2.

[0032] Controllable feeding: When the telescopic rod 9 pushes or pulls the turntable 8 to a specific position, the turntable 8 aligns vertically with the feeding holes on the fixed plate 7, forming a channel. The organic fertilizer and chemical fertilizer above fall through their respective feeding holes under gravity. By controlling the movement frequency and stroke of the telescopic rod 9, the amount of organic fertilizer and chemical fertilizer falling per unit time can be precisely controlled.

[0033] Preliminary mixing and flow guidance: When the two fertilizers fall into the flow guide hood 10 area, they are broken up and initially mixed by the high-speed rotating stirring blades 12.

[0034] Final mixing and uniform spreading: The fertilizer, after preliminary mixing, falls onto the high-speed rotating spreading disc 13. Under the action of centrifugal force, the fertilizer is scattered outward and upward. The centrifugal spreading process ensures the final uniform mixing of organic fertilizer and chemical fertilizer and achieves a wide and uniform fertilization effect.
