Abstract
Description
Technical Field
[0001] This utility model belongs to the field of fertilizer equipment technology, specifically referring to a soil fertilizer mixing device. Background Technology
[0002] Fertilizer is crucial for crop growth, and its uniform mixing and efficient application directly affect crop yield and quality. Livestock farming generates a large amount of manure that cannot be used directly and needs to be mixed with plant straw for fermentation and composting.
[0003] However, when mixing existing soil fertilizers, most methods involve spreading a layer of plant stalks on top of manure, and then spreading a layer of manure on top of plant stalks to achieve composting. This uneven mixing of manure and plant stalks affects the fermentation effect, resulting in incomplete fermentation and damage to the roots of crops. Summary of the Invention
[0004] In response to the above situation and to overcome the shortcomings of the existing technology, this utility model proposes a soil fertilizer mixing device, which effectively solves the problem that in most soil fertilizer mixing processes, plant straw is spread on top of manure, and then manure is spread on top of plant straw to achieve composting. However, this results in uneven mixing of manure and plant straw, affecting the fermentation effect, causing incomplete fermentation, and damaging the roots of crops.
[0005] The technical solution adopted by this utility model is as follows: This utility model proposes a soil fertilizer mixing device, including a base, a mixing structure and a discharge structure. The mixing structure is disposed on the base, and the discharge structure is disposed on the base and located below the mixing structure. The mixing structure includes a stirring unit and a feeding unit. The stirring unit is disposed on the base, and the feeding unit is disposed on the base.
[0006] The mixing unit includes a fixed base, a motor, a rotating shaft, a mixing trough, mixing teeth, and a gear. The fixed base is fixedly mounted on the bottom of the base. The motor is fixedly mounted on the fixed base. The rotating shaft passes through the base and is rotatably mounted, with one end fixedly mounted on the output shaft of the motor. The mixing trough passes through the rotating shaft and is rotatably mounted. The mixing teeth are fixedly mounted on the rotating shaft and located inside the mixing trough. The gear passes through the rotating shaft and is fixedly mounted on both sides of the mixing trough.
[0007] Preferably, the feeding unit includes a fixed base two, a motor two, and a gear two. The fixed base two is fixedly mounted on the top of the base, the motor two is fixedly mounted on the fixed base two, and the gear two is fixedly mounted on the output shaft of the motor two and meshes with the gear one.
[0008] To achieve better emission results, the emission structure includes a conveying pipe, a hopper, a third motor, a second rotating shaft, and a conveying paddle. The conveying pipe is fixedly installed at the bottom of the base, the hopper is located above the conveying pipe, the third motor is fixedly installed on a first fixed base, the second rotating shaft passes through the conveying pipe and is rotatably mounted on the third motor, and the conveying paddle is spirally wrapped around the second rotating shaft.
[0009] To achieve efficient mixing more quickly, the hopper is located below the rotating shaft.
[0010] Furthermore, the mixing tank is U-shaped, and two sets of gears are arranged on both sides of the mixing tank. Two sets of motors drive the two sets of gears to rotate.
[0011] To achieve the desired conveying effect, the conveying paddle is configured in a spiral shape.
[0012] The beneficial effects of this utility model using the above structure are as follows: The soil fertilizer mixer proposed in this solution uses a motor to drive the rotating shaft and the mixing teeth on it to rotate evenly, so that the mixture of manure and plant straw in the mixing trough can be discharged by turning the mixing trough over, thereby improving the mixing efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention proposes a soil fertilizer mixing device, which includes a base 1, a mixing structure 2 and a discharge structure 3. The mixing structure 2 is disposed on the base 1, and the discharge structure 3 is disposed on the base 1 and located below the mixing structure 2. The mixing structure 2 includes a stirring unit 4 and a feeding unit 5. The stirring unit 4 is disposed on the base 1, and the feeding unit 5 is disposed on the base 1.
[0021] The mixing unit 4 includes a fixed base 6, a motor 7, a rotating shaft 8, a mixing trough 9, mixing teeth 10, and a gear 11. The fixed base 6 is fixedly mounted on the bottom of the base 1. The motor 7 is fixedly mounted on the fixed base 6. The rotating shaft 8 passes through the base 1 and is rotatably mounted, with one end fixed to the output shaft of the motor 7. The mixing trough 9 is U-shaped and rotatably mounted through the rotating shaft 8. The mixing teeth 10 are fixedly mounted on the rotating shaft 8 and located inside the mixing trough 9. The gear 11 passes through the rotating shaft 8 and is fixedly mounted on both sides of the mixing trough 9.
[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the feeding unit 5 includes a fixed base 12, a motor 13, and a gear 14. The fixed base 12 is fixedly mounted on the top of the base 1, the motor 13 is fixedly mounted on the fixed base 12, and the gear 14 is fixedly mounted on the output shaft of the motor 13 and meshes with the gear 11. Two sets of gears 11 are arranged on both sides of the mixing tank 9. The two sets of motors 13 synchronously drive the two sets of gears 14 to rotate the gear 11.
[0023] like Figure 1 , Figure 2 and Figure 4 As shown, the discharge structure 3 includes a conveying pipe 15, a hopper 16, a motor 17, a rotating shaft 18, and a conveying paddle 19.

The motor 17 is fixedly installed on the fixed base 6. The rotating shaft 18 passes through the conveying pipe 15 and is rotatably mounted on the motor 17. The conveying paddle 19 is spirally wrapped around the rotating shaft 18 and has a spiral structure.
[0024] In practical use, first, put the manure into the mixing trough 9, and at the same time, add the plant straw into the mixing trough 9. Control the motor 7 to drive the rotating shaft 8 to rotate in the mixing trough 9, so that the plant straw and manure in the mixing trough 9 are mixed evenly. After the mixture is evenly mixed, control the two sets of motors 13 to drive the two sets of gears 14 to mesh and drive the gear 11 to rotate. The gear 11 then drives the mixing trough 9 to flip. At this time, the evenly mixed fertilizer in the mixing trough 9 falls into the hopper 16. Then, control the motor 17 to drive the conveying plate 19 on the rotating shaft 18 to rotate in the conveying pipe 15. The conveying plate 19 pushes the fertilizer in the hopper 16 out of the composting tank through the conveying pipe 15, so as to quickly complete the even mixing and improve the composting effect. The above is the entire process of using the soil fertilizer mixer.
