Abstract
Description
Technical Field
[0001] This utility model relates to the field of organic fertilizer technology, specifically to an organic fertilizer mixing device. Background Technology
[0002] Organic fertilizers, also known as farmyard manure, refer to any fertilizer made from organic matter. These include manure, compost, green manure, oilseed cake, and biogas slurry. They are characterized by their variety, wide availability, and long-lasting effects. The nutrients in organic fertilizers are mostly in an organic state, making them difficult for crops to utilize directly. Through the action of microorganisms, they slowly release various nutrients, continuously supplying the crops. Furthermore, applying organic fertilizers can effectively improve soil structure by coordinating key factors such as water, nutrients, air, and temperature, comprehensively enhancing soil fertility and increasing land productivity. However, single-variety organic fertilizers often suffer from limited nutrient composition and fertility. Therefore, in practical applications, it is usually necessary to scientifically mix multiple fertilizers to achieve nutrient complementarity and improved efficiency.
[0003] However, existing technologies have the following problems in practical use;
[0004] Even after initial processing such as composting, some organic fertilizers still retain a certain degree of stickiness. When mixing organic fertilizers with traditional equipment, the fertilizer tends to stick to the inner wall of the equipment, often requiring manual cleaning by staff. Furthermore, the organic fertilizers react during mixing, releasing irritating gases that create a strong odor inside the tank. As the gases react for a long time inside the sealed tank, they are expelled along with the fertilizer, easily causing severe irritation to the eyes and nasal mucosa of the operators. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] To overcome the aforementioned deficiencies of the prior art, this utility model provides an organic fertilizer mixing device, which solves the problem mentioned in the background art that after the organic fertilizer has undergone preliminary treatment such as composting, it still has a certain degree of stickiness. When mixing organic fertilizer with traditional equipment, the organic fertilizer is more likely to stick to the inner wall of the equipment, which often requires manual cleaning by the staff. In addition, the organic fertilizer will react during stirring and mixing, releasing irritating gases and forming a strong odor inside the tank. The gas reacts inside the sealed tank for a long time, and when the fertilizer is discharged, the gas will be discharged with the fertilizer, which can easily cause strong irritation to the mucous membranes of the operator's eyes and nose.

[0016] (III) Beneficial Effects
[0017] This utility model provides an organic fertilizer mixing device, which has the following beneficial effects:
[0018] This organic fertilizer batching device, through the coordinated arrangement of a limiting frame, drive shaft, arc-shaped scraper, and drive motor, allows the drive motor to rotate the rotating shaft during actual use. The rotation of the drive shaft, in turn, causes the arc-shaped scraper and serrated blades to rotate synchronously.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the 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 scope of protection of the present utility model.
[0026] Example 1;
[0027] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 This utility model provides a technical solution: an organic fertilizer batching device, including a mixing tank 1, a sealing cover 2, a discharge assembly 3, and a control box 15. The inner wall of the mixing tank 1 is provided with two arc-shaped scrapers 4, symmetrically arranged about the vertical center line of the mixing tank 1. The outer surfaces of both arc-shaped scrapers 4 are in contact with the inner wall of the mixing tank 1. A limiting frame 5 is fixedly connected to the upper end of the arc-shaped scrapers 4. A drive shaft 6 is detachably connected to the inner wall of the limiting frame 5. Multiple serrated blades 7 are arranged sequentially from top to bottom on the outer surface of the drive shaft 6. A drive motor 8 is located in the middle of the upper end of the sealing cover 2. The output end of the drive motor 8 passes through one side of the sealing cover 2 and is engaged with one end of the drive shaft 6. Inside the sealing cover 2, a negative pressure exhaust fan 9 is provided on the upper end of the sealing cover 2 near the drive motor 8. An activated carbon filter box 10 is provided on the upper end of the negative pressure exhaust fan 9. The input ends of the drive motor 8 and the negative pressure exhaust fan 9 are connected to the output end wires of the control box 15. Multiple through holes are provided on the upper surfaces of the mixing tank 1 and the sealing cover 2. Each through hole is provided with a fastening bolt 17, and a fastening nut 18 is threaded to one end of each fastening bolt 17. A feed pipe 19 is provided on the upper end of the sealing cover 2 near the drive motor 8 and away from the negative pressure exhaust fan 9. A control button 20 is provided on the outer surface of the control box 15. A warning light 21 is provided on the outer surface of the control box 15 near the control button 20.
[0028] Through the above technical solution, the fastening bolt 17 forms a high-strength rigid connection structure by passing through the through holes at corresponding positions of the mixing tank 1 and the sealing cover 2. During equipment assembly, by evenly tightening the fastening bolt 17 and the fastening nut 18, the mating surface of the sealing cover 2 and the mixing tank 1 can form uniform pressure, effectively eliminating gaps. This ensures a sealed environment inside the mixing tank 1 during mixing operations, preventing material splashing and gas leakage. It also provides a stable installation foundation for upper components such as the drive motor 8 and the negative pressure exhaust fan 9. Furthermore, the feed pipe 19 can serve as an inlet for organic fertilizer raw materials, connecting to external raw material pipelines to facilitate the addition of different raw materials from above into the mixing tank 1, preventing raw materials from spilling during the feeding process. It also facilitates continuous feeding operations and improves batching efficiency. The control button 20 on the side of the control box 15 can start and stop the equipment and set the equipment's operating parameters. When abnormal conditions occur during equipment operation, the warning light 21 will illuminate to remind the operator to handle the problem in time and avoid equipment damage or production accidents.
[0029] Example 2;
[0030] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a technical solution based on Embodiment 1. A support frame 11 is provided on the outer surface of the mixing tank 1. Pressure plates 12 are provided at the four corners of the lower end of the support frame 11. A load-bearing plate 13 is provided on the inner wall of the support frame 11. The upper end of the load-bearing plate 13 is in contact with the lower end of the discharge assembly 3. An electric knife gate valve 14 is provided at the lower end of the mixing tank 1. The input end of the electric knife gate valve 14 is connected to the output end of the control box 15 via a wire. A discharge pipe 16 is provided at the lower end of the electric knife gate valve 14. The other end of the discharge pipe 16 is connected to the input flange of the discharge assembly 3. The discharge assembly 3 includes a conveying pipe 301. The outer surface of the conveying pipe 301... The other end of the conveying pipe 301 is connected to the flange of the discharge pipe 16. The inside of the conveying pipe 301 is provided with a rotating shaft 302. The outer surface of the rotating shaft 302 is provided with a spiral blade 303. One end of the conveying pipe 301 is detachably connected to a bearing seat 304. One end of the rotating shaft 302 passes through the bearing seat 304, and the connection between the rotating shaft 302 and the bearing seat 304 is a snap-fit. The other end of the conveying pipe 301 is detachably connected to a servo motor 305. The output end of the servo motor 305 passes through one side of the conveying pipe 301 and is snap-fitted into the inside of the rotating shaft 302. The outer surface of the conveying pipe 301 is provided with a discharge pipe 306 on the side near the bearing seat 304.
[0031] Through the above technical solution, the support frame 11 can support the mixing tank 1, fix the mixing tank 1 at a certain height, and through the pressure plate 12 at the lower end, it can increase the contact area between the support frame 11 and the ground, distribute the weight of the equipment, prevent the equipment from damaging the ground, and improve the stability of the equipment. After the mixing is completed, when it is necessary to discharge, the control box 15 can be operated to control the opening or closing of the electric knife gate valve 14, so as to realize the quantitative discharge or stop the discharge of fertilizer. The electric knife gate valve 14 can realize the precise control of the discharge flow rate. The fertilizer enters the interior of the conveying pipe 301 through the electric knife gate valve 14 and the discharge pipe 16. The conveying pipe 301 serves as the conveying pipe for the fertilizer after it is discharged from the mixing tank 1. The servo motor 305 at one end of the conveying pipe 301 provides driving force to the rotating shaft 302 inside the conveying pipe 301, causing the rotating shaft 302 to drive the spiral blades 303 to rotate, thereby pushing the fertilizer. This avoids the funnel effect that may occur when traditional equipment relies on gravity to discharge fertilizer, and the unevenness caused by the preferential discharge of fertilizer in the center. It can also reduce the risk of fiber or block materials entanglement and facilitate the conveying of highly viscous organic fertilizers. At the same time, the discharge pipe 306 can discharge the fertilizer inside the conveying pipe 301 and transport it to subsequent processing equipment or storage containers. When the rotating shaft 302 rotates, its bearing seat 304 can support the rotating shaft 302, so that the rotating shaft 302 can rotate stably.
[0032] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power via standard interfaces. The main controller can be any commercially available known device. There are no special restrictions on the specific models of the electrical components; any commercially available ordinary products can be selected, as long as they meet the usage requirements of this utility model.
[0033] In this invention, the working steps of the device are as follows:
[0034] First, connect the external fertilizer pipeline to the feed pipe 19. Operate the control box 15 to close the electric knife gate valve 14. Then, switch the servo motor 305 to standby mode, and stop the spiral blades 303 from rotating. After the external fertilizer is fed, start the negative pressure exhaust fan 9 via the control button 20 to extract air from the inside of the mixing tank 1. Start the drive motor 8; the power of the drive motor 8 is transmitted through the transmission shaft 6, causing the serrated blades 7 and the arc-shaped scraper 4 to rotate synchronously. The serrated blades 7 rotate to cut and mix the raw materials, breaking up lumpy materials and ensuring uniform mixing. Simultaneously, the arc-shaped scraper 4 rotates against the inner wall of the mixing tank 1, scraping away any material adhering to the tank wall to prevent uneven mixing caused by residue. Odor gases generated during the mixing process are eliminated under negative pressure. The activated carbon filter box 10 is filled with activated carbon to remove odors and harmful substances. The purified gas is then discharged, improving the working environment. After mixing, the drive motor 8 is stopped by the control button 20, while the negative pressure exhaust fan 9 is kept running. The electric knife gate valve 14 is opened by the operation control box 15. The evenly mixed raw material enters the conveying pipe 301 through the electric knife gate valve 14 and the discharge pipe 16. Then, the servo motor 305 is started, which drives the rotating shaft 302 and the spiral blade 303 to rotate. The spiral blade 303 pushes the raw material in the conveying pipe 301 axially to the discharge pipe 306 and finally delivers it to the subsequent processing equipment. After the discharge is completed, the electric knife gate valve 14 is closed to cut off the raw material channel, the servo motor 305 is stopped, and the main stop button of the control box 15 is pressed to ensure that the equipment is in the off state.
