Description

Technical Field

[0001] This utility model relates to the field of automatic mixing device technology, and in particular to an automatic mixing device for compound fertilizer. Background Technology

[0002] Compound fertilizers are fertilizers made by chemical or physical methods, combining two or more essential plant nutrients (such as nitrogen, phosphorus, and potassium) in specific proportions and forms. Compared to single-element fertilizers, compound fertilizers offer advantages such as high nutrient content, a complete range of nutrients, scientifically formulated proportions, and convenient application, effectively meeting the diverse nutrient needs of crops at different growth stages. Common forms include granules, powders, and liquids, allowing for flexible selection based on crop type, soil conditions, and application methods. They are widely used in agricultural production to promote healthy crop growth and improve the yield and quality of agricultural products.

[0003] Currently, most existing automatic compound fertilizer mixing devices use a direct addition method, where two or more fertilizers are directly added to the mixing tank and then mixed. This direct addition method easily leads to localized aggregation of single-element fertilizers, resulting in overall proportion deviations and uneven mixing in the compound fertilizer. Furthermore, existing mixing devices struggle to achieve efficient and uniform mixing when handling fertilizers with different physical properties (such as particle size and density), further limiting the quality and effectiveness of the compound fertilizer. Therefore, they have certain limitations in their application.

[0004] Based on this, we propose an automatic compound fertilizer mixing device to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide an automatic compound fertilizer mixing device that can solve the problems of local aggregation of single-element fertilizers, ratio deviation and uneven mixing caused by the direct delivery method of existing devices, as well as the difficulty in achieving efficient and uniform mixing when processing fertilizers with different physical properties.

[0007] To solve the above technical problems, this utility model provides an automatic compound fertilizer mixing device, which adopts the following technical solution: it includes a mixing tank, a driving component is installed on the top of the mixing tank, a first feeding hopper is connected to the top side of the mixing tank near the driving component, and a second feeding hopper is also provided on the top side of the mixing tank away from the first feeding hopper.

[0008] The mixing tank is equipped with a support base at the bottom, and a discharge port is provided on one side of the mixing tank. The top of the mixing tank has two sets of feed inlets, and wedge-shaped grooves are provided around the openings of the two sets of feed inlets. The mixing tank has a mixing cavity inside, and a spiral stirring shaft is connected to the inside of the mixing cavity through a bearing.

[0009] Optionally, a feeding connector is installed at the bottom of the second feeding hopper, a rotating feeding disc is connected to the middle of the feeding connector, and a wedge-shaped clamping plate is also provided at the bottom of the feeding connector. The wedge-shaped clamping plate matches the wedge-shaped groove structure, and the wedge-shaped clamping plate and the wedge-shaped groove are engaged.

[0010] Optionally, the drive assembly includes a stirring motor, a drive bracket is mounted on the bottom of the stirring motor, a drive wheel is driven to the output end of the stirring motor, the drive wheel is located inside the drive bracket, and the drive wheel is driven to the spiral stirring shaft.

[0011] Optionally, an adjusting shaft is installed in the middle of the feeding connecting seat, and annular grooves are provided on both sides of the inner wall of the feeding connecting seat.

[0012] Optionally, a pulley groove is provided in the middle of the outer side of the rotating feeding disc, a shaft hole is provided through the middle of the rotating feeding disc, a number of discharge holes distributed in a circular array are provided around the rotating feeding disc and the feeding connecting seat, and sealing rings are provided on both sides of the rotating feeding disc.

[0013] Optionally, the shaft hole matches the adjusting shaft structure, and the sealing ring and the annular groove have a transition fit.

[0014] In summary, this utility model has at least one of the following beneficial effects: This solution, through the dynamic control of the rotating feeding disc, ensures that the fertilizer of the second element enters the mixing tank at a uniform speed and is fully mixed with the fertilizer of the first element. The rotating feeding disc is connected to the drive assembly via a transmission belt, enabling precise control of the feeding speed and position, avoiding the localized aggregation problem caused by direct feeding in traditional devices. Combined with the high-speed rotation of the spiral stirring shaft, the fertilizer is fully tumbled and dispersed during the mixing process, ensuring that fertilizers with different physical properties can fully contact and be evenly distributed. Simultaneously, by controlling the position of the discharge hole, the rotating feeding disc ensures that different fertilizers enter the mixing tank at a uniform speed. This structural design not only improves the mixing uniformity of the fertilizer but also ensures that the proportion of each nutrient element in the compound fertilizer meets agricultural needs, thereby improving the overall quality of the fertilizer.

[0024] Example: Refer to Figures 1 to 6 This utility model provides an embodiment of an automatic compound fertilizer mixing device, including a mixing tank 1, a drive assembly 2 installed on the top of the mixing tank 1, a first feed hopper 3 connected to the top side of the mixing tank 1 near the drive assembly 2, a second feed hopper 4 also provided on the top side of the mixing tank 1 away from the first feed hopper 3, a support base 5 installed at the bottom of the mixing tank 1, a discharge port 6 provided on one side of the mixing tank 1, two sets of feed inlets 7 opened on the top of the mixing tank 1, wedge-shaped grooves 8 respectively opened around the openings of the two sets of feed inlets 7, a mixing cavity 9 opened inside the mixing tank 1, and a spiral stirring shaft 10 connected inside the mixing cavity 9 through a bearing. This automatic mixing device, through the cooperation of the drive assembly 2 and the second feed hopper 4, can automatically feed a second element fertilizer while simultaneously mixing and stirring the fed second element fertilizer with the first element fertilizer, which can effectively improve the uniformity of mixing two or more fertilizers and avoid the problem of local aggregation of single element fertilizer caused by direct feeding.

[0025] The bottom of the second feed hopper 4 is equipped with a discharge connecting seat 11, and a rotating discharge disc 12 is connected to the middle of the discharge connecting seat 11. A wedge-shaped clamping plate 13 is also provided at the bottom of the discharge connecting seat 11. The wedge-shaped clamping plate 13 matches the structure of the wedge-shaped groove 8, and the wedge-shaped clamping plate 13 and the wedge-shaped groove 8 are in a snap-fit ​​engagement. Through the snap-fit ​​engagement structure between the wedge-shaped clamping plate 13 and the wedge-shaped groove 8, the first feed hopper 3 and the second feed hopper 4 can be locked and secured to the top of the mixing tank 1. Furthermore, the mixing tank 1 can disassemble, connect, repair, and replace the first feed hopper 3 and the second feed hopper 4 according to the different physical properties of the fertilizer (such as particle size and density). The drive assembly 2 includes a stirring motor 14, and a drive bracket 15 is installed at the bottom of the stirring motor 14. The output end of the stirring motor 14 is connected to a transmission... The drive wheel 16 is located inside the drive bracket 15. The drive wheel 16 is connected to the spiral stirring shaft 10. The drive wheel 16 is connected to the output end of the stirring motor 14. When the stirring motor 14 is powered on, it can drive the spiral stirring shaft 10 connected to the output end to rotate inside the mixing tank 1. It can also drive the rotating feeding disc 12 to rotate synchronously inside the feeding connecting seat 11 through the transmission belt. An adjusting shaft 17 is installed in the middle of the feeding connecting seat 11. Annular grooves 18 are opened on both sides of the inner wall of the feeding connecting seat 11. The rotating feeding disc 12 can be rotatably connected to the middle of the feeding connecting seat 11 by the adjusting shaft 17 installed in the middle of the feeding connecting seat 11.

[0027] Working Principle: The automatic compound fertilizer mixing device designed in this scheme mainly consists of a mixing tank 1, a drive assembly 2, a first feed hopper 3, and a second feed hopper 4. The drive assembly 2 is connected to the rotating feeding disc 12 installed at the bottom of the second feed hopper 4 via a transmission belt. When the stirring motor 14 is powered on, it can drive the spiral stirring shaft 10 connected to the output end to rotate inside the mixing tank 1. Through the cooperation between the rotating feeding disc 12, the transmission wheel 16, and the transmission belt, the rotating feeding disc 12 can also be driven to rotate synchronously inside the feeding connecting seat 11. The rotating feeding disc 12 and the feeding connecting seat 11 are connected by a through-hole... The discharge holes 21 are designed such that when the rotating feeding disc 12 rotates inside the feeding connecting seat 11, the discharge holes 21 on the rotating feeding disc 12 can be misaligned or coincident with the discharge holes 21 on the feeding connecting seat 11. When the two sets of discharge holes 21 coincide, the fertilizer stored in the second feeding hopper 4 can fall into the mixing tank 1. When the two sets of discharge holes 21 are misaligned, the fertilizer stored in the second feeding hopper 4 cannot fall into the mixing tank 1. This can effectively improve the uniformity of mixing two or more fertilizers and avoid the problem of local aggregation of single-element fertilizers caused by direct feeding.
