Description

Technical Field

[0001] This utility model belongs to the field of fertilizer mixing technology, specifically relating to a fertilizer mixing device with automatic feeding function. Background Technology

[0002] Chemical fertilizers are one or more essential nutrients for the growth and development of any plant, whether natural or synthetic. Approximately 30% to 50% of increased crop yields are attributed to commercially available fertilizers, whether natural or inorganically synthesized. There are numerous types and brands of fertilizers on the market, which can be categorized into inorganic and organic fertilizers based on their composition. Fertilizers are typically applied directly to the soil or sprayed onto the leaves.

[0003] Traditional equipment requires manual handling of raw materials, dumping, and proportioning, which is inefficient and prone to errors due to operational mistakes. Furthermore, existing equipment lacks a pre-treatment module (such as crushing), and direct mixing of lumpy raw materials can easily lead to uneven mixing, affecting the fertilizer efficiency of the finished product. In addition, the non-enclosed feeding process can easily introduce dust and impurities, and the release of volatile substances can harm the working environment. Summary of the Invention

[0015] 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. Example

[0016] Please see Figure 1-4 The technical solution provided in this embodiment is as follows: A fertilizer mixing device with automatic feeding function includes: a mixing mechanism 1, and a feeding mechanism 2 fixedly connected to the rear side of the mixing mechanism 1; The mixing mechanism 1 includes a mixing frame 101, a mixing tank 102 rotatably connected to the surface of the mixing frame 101, a mixing tank 102 rotatably connected to the surface of the mixing frame 101, and a mixing paddle 104 rotatably connected to the inside of the mixing tank 102; The feeding mechanism 2 includes a feeding cylinder 201 fixedly connected to the rear side of the mixing frame 101. A conveying auger 202 is rotatably connected inside the feeding cylinder 201. A transfer bucket 204 is fixedly connected to the lower side of one side of the feeding cylinder 201, and a feeding hopper 205 adapted to the mixing tank 102 is fixedly connected to the upper side of the other side of the feeding cylinder 201. A crushing box 206 is fixedly connected to the upper surface of the transfer bucket 204. Two crushing rollers 207 are rotatably connected inside the crushing box 206, and a feeding hopper 208 is fixedly connected to the upper surface of the crushing rollers 207. Through the integrated feeding mechanism 2, automatic lifting, crushing, and conveying of raw materials are achieved. The transfer bucket 204 and the conveying auger 202 replace manual handling. The crushing rollers 207 simultaneously pre-treat the raw materials, reducing process connection time. The double-roller crushing inside the crushing box 206 eliminates agglomeration, ensuring particle uniformity. The closed conveyor chain prevents external contaminants from entering. The mixing paddle 104 performs multi-directional stirring to improve material mixing and avoid local concentration deviations caused by dead zones in traditional equipment.

[0017] Specifically, a first servo motor 103 is fixedly connected to one side of the mixing tank 102, and the output shaft of the first servo motor 103 is fixedly connected to one end of the mixing paddle 104.

[0018] In a specific embodiment of this utility model, the first servo motor 103 directly drives the mixing paddle 104 to rotate. By adjusting the speed and direction of the first servo motor 103, the mixing intensity and time can be precisely controlled to adapt to different fertilizer ratio requirements, avoid energy loss from traditional mechanical transmission, and improve energy efficiency.

[0019] Specifically, electric cylinders 106 are rotatably connected to both sides of the inner wall of the mixing rack 101. A connector 105 is rotatably connected to the surface of the piston rod of the electric cylinder 106, and the connector 105 is rotatably connected to the mixing barrel 102.

[0020] In a specific embodiment of this utility model, the electric cylinder 106 pushes the mixing tank 102 through the connector 105 to adjust the discharge tilt angle, and the adjustable angle can adapt to various receiving equipment to avoid residue.

[0021] Specifically, a second servo motor 203 is fixedly connected to the top of the feeding cylinder 201, and the output shaft of the second servo motor 203 is fixedly connected to the top of the conveying auger 202.

[0022] In a specific embodiment of this utility model, the second servo motor 203 drives the conveying auger 202 to continuously convey the crushed material to the mixing tank 102. The conveying auger 202 feeds the material at a uniform speed to ensure the accuracy of the proportioning. Moreover, the conveying auger 202 has a structure that prevents clogging and is suitable for powdery or granular fertilizers.

[0023] Specifically, both sides of the upper surface of the feed hopper 208 are rotatably connected to a sealing cover 209, and a movable handle 210 is fixedly connected to the surface of the sealing cover 209.

[0024] In a specific embodiment of this utility model, the sealing cover 209 is opened and closed by moving the handle 210, covering the top of the feed hopper 208, preventing moisture and dust, ensuring the stability of raw materials, reducing the emission of volatiles, and improving the working environment.

[0025] Specifically, transmission gears 211 are fixedly connected to the surfaces of both crushing rollers 207, and the two transmission gears 211 mesh. A third servo motor 212 is fixedly connected to the surface of the crushing box 206, and the output shaft of the third servo motor 212 is fixedly connected to one of the crushing rollers 207.

[0026] In a specific embodiment of this utility model, a third servo motor 212 drives a crushing roller 207, which in turn drives another roller to rotate in the opposite direction through a meshing transmission gear 211. The opposing movement of the two crushing rollers 207 improves the crushing efficiency, while the synchronous movement of the transmission gear 211 avoids material jamming and extends the equipment life.

[0027] Working principle: Raw materials enter the crushing box 206 through the feed hopper 208. The double crushing rollers 207 rotate in opposite directions under gear transmission to crush lumps or large particles, ensuring uniform particle size. After crushing, the material falls into the transfer hopper 204 and is lifted to the top of the feeding cylinder 201 by the conveying auger 202 driven by the second servo motor 203. It is then fed into the mixing tank 102 through the discharge hopper 205. The structure of the conveying auger 202 ensures continuous feeding and no dust leakage. At the same time, the mixing paddle 104 in the mixing tank 102 rotates under the drive of the first servo motor 103, forming a vortex to achieve multi-directional mixing. Meanwhile, the electric cylinder 106 can adjust the angle of the tank body to optimize the mixing trajectory. After mixing is completed, the electric cylinder 106 pushes the mixing tank 102 to tilt, and the mixing tank 102 automatically discharges through the tank opening. The sealing cover 209 and the closed pipe design reduce residue and facilitate cleaning.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
