Description

Technical Field

[0001] This utility model relates to the field of herbicide preparation technology, specifically to an automatic proportioning and mixing device for herbicide production. Background Technology

[0002] Herbicides are widely used to control weeds, shrubs, and trees in farmland, orchards, flower nurseries, grasslands and non-arable land, railway lines, rivers, reservoirs, warehouses and other places. Herbicides require the addition of various raw materials in different amounts during preparation.

[0003] A search revealed a Chinese patent publication number: CN216149477U, which provides a quantitative proportioning device for preparing mixed herbicides. This patent incorporates a sensing component. Rotating the rotating rod in the sensing component causes the engaging connecting block to raise or lower a water level sensor to a certain height. This height indicates the level of the raw material to be added. Once the water level sensor detects the level of the raw material, it controls the electric valve to open and complete the proportioning process, resulting in high proportioning efficiency.

[0004] Although the aforementioned patents can improve the proportion of raw materials, the aforementioned devices still have the following problems: during the stirring process of liquid herbicides with high viscosity (such as high molecular weight polymer components), the raw materials tend to adhere to the inner wall and bottom of the device, forming residues. For example, when the concentration of amino acid herbicides and glufosinate sulfate solution exceeds 30%, crystals easily precipitate at low temperatures and adhere to the bottom of the tank. Concentrated solutions of organophosphorus herbicides, glyphosate (salt aqueous solution), and glyphosate ammonium and potassium salts tend to crystallize and stick to the wall. The adhered materials cannot be fully stirred, resulting in insufficient mixing. In view of the above situation, technological innovation is carried out on the basis of the existing device. Utility Model Content

[0005] The purpose of this invention is to provide an automatic proportioning and mixing device for herbicide production, in order to solve the problems mentioned in the background art: during the stirring process of liquid herbicide raw materials, the raw materials will adhere to the inner wall and bottom of the container, and the adhered materials cannot be fully stirred, resulting in insufficient mixing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic proportioning and mixing device for herbicide production, comprising a mixing tank, a motor fixedly connected to the top of the mixing tank, a proportioning tank disposed on the top of the mixing tank, a conveying pipe fixedly connected to the bottom of the proportioning tank, a baffle fixedly connected inside the mixing tank, the baffle dividing the internal space of the mixing tank into an upper fixed cavity and a lower mixing cavity, the conveying pipe penetrating the surface of the mixing tank and extending into the interior of the fixed cavity, a rotating sleeve rotatably connected to the surface of the conveying pipe, a second gear fixedly connected to the surface of the rotating sleeve, a rotating rod rotatably connected inside the fixed cavity, the output end of the motor rotatably penetrating the surface of the mixing tank and extending into the interior of the fixed cavity, the output end of the motor being fixedly connected to one end of the rotating rod via a coupling, a first gear fixedly connected to the surface of the rotating rod, the surface of the first gear meshing with the surface of the second gear, and a movable sleeve slidably connected to the surface of the rotating sleeve.

[0021] Please see Figure 1-4 This utility model provides a technical solution: an automatic proportioning and mixing device for herbicide production, including a mixing tank 1. A motor 4 is fixedly connected to the top of the mixing tank 1. The motor 4 is an existing structure and will not be described in detail here. A proportioning tank 3 is set on the top of the mixing tank 1. A sensing component is set inside the proportioning tank 3. Rotating the sensing component can cause the connecting block engaged with it to drive the water level sensor to rise or fall to a certain height. This height is the height of the raw material to be added. After the water level sensor senses the raw material at this height, it will control the electric valve to open to complete the proportioning. This technical means has been disclosed in the prior art and will not be discussed in detail here.

[0022] A conveying pipe 8 is fixedly connected to the bottom of the mixing tank 3. The proportioned liquid herbicide raw material is conveyed through the conveying pipe 8. A baffle 10 is fixedly connected inside the mixing tank 1, dividing the internal space of the mixing tank 1 into an upper fixed cavity 22 and a lower mixing cavity 11. The conveying pipe 8 penetrates the surface of the mixing tank 1 and extends into the interior of the fixed cavity 22. A rotating sleeve 21, which communicates with the interior of the conveying pipe 8, is rotatably connected to the surface of the conveying pipe 8. A second gear 9 is fixedly connected to the surface of the rotating sleeve 21. A rotating rod 6 is rotatably connected inside the fixed cavity 22. The output end of the motor 4 rotates through the mixing tank. The surface of the tank 1 extends into the interior of the fixed cavity 22. The output end of the motor 4 is fixedly connected to one end of the rotating rod 6 via a coupling. The surface of the rotating rod 6 is fixedly connected to the first gear 7, and the surface of the first gear 7 meshes with the surface of the second gear 9. The surface of the rotating sleeve 21 is slidably connected to the movable sleeve 12, which penetrates the surface of the baffle 10 and slides against the interior of the baffle 10. The lower end of the rotating sleeve 21 is fixedly connected to the scraper 14, which has an L-shaped cross-section. The surface of the scraper 14 contacts the inner wall of the mixing chamber 11. The surface of the movable sleeve 12 is fixedly connected to the stirring rod 13.

[0023] Workers inject the liquid herbicide raw material into the mixing tank 3. Then, the worker starts the motor 4, which drives the rotating rod 6 to rotate. Simultaneously, the rotating rod 6 drives the first gear 7 to rotate, which in turn drives the second gear 9 through meshing. The second gear 9 then drives the rotating sleeve 21 to rotate, which in turn drives the movable sleeve 12 to rotate. The movable sleeve 12 then drives the stirring rod 13 to rotate and stir. Simultaneously, the rotating sleeve 21 drives the scraper 14 to rotate and scrape the inner wall of the mixing chamber 11. This stirring and scraping of the mixing chamber 11 prevents raw materials from adhering to the inner wall and bottom, affecting stirring and ensuring proportioning accuracy and mixing uniformity. Simultaneous scraping during stirring removes any adhering raw materials and re-introduces them into the mixing flow, reducing waste. This achieves multiple optimizations in material mixing and anti-adhesion, ensuring uniform pesticide composition, avoiding raw material waste, improving production stability, reducing energy consumption and maintenance costs, and enhancing the practicality of the equipment.

[0024] A water injection pipe 2 is fixedly connected to the top of the mixing tank 1. One end of the water injection pipe 2 passes through the inside of the fixed cavity 22 and extends into the inside of the mixing chamber 11. Water can be injected into the inside of the mixing chamber 11 through the water injection pipe 2.

[0025] A discharge pipe 5 is fixedly connected to one side of the mixing tank 1.

[0026] Two protrusions 17 are fixedly connected to the surface of the baffle 10. The cross-section of the protrusions 17 is triangular and the top is arc-shaped.

[0027] A rotating disk 16 is fixedly connected to the surface of the movable sleeve 12, and a sliding rod 18 is fixedly connected to the bottom of the rotating disk 16. The sliding rod 18 has an L-shaped cross section, and the surface of the sliding rod 18 is in contact with the inner wall of the protrusion 17.

[0028] Both the movable sleeve 12 and the rotating sleeve 21 have conveying ports 15 that penetrate their surfaces, through which liquid herbicide raw materials can be discharged into the mixing chamber 11.

[0029] The rotating sleeve 21 is fixedly connected to the surface of the locking block 19, and the movable sleeve 12 is provided with a locking groove 23. The surface of the locking block 19 is slidably connected to the inside of the locking groove 23. Two springs 20 are fixedly connected to the inside of the locking groove 23, and the end of the spring 20 near the locking block 19 is fixedly connected to the surface of the locking block 19.

[0030] When the operator starts motor 4, the output of motor 4 drives rotating rod 6 to rotate. Simultaneously, rotating rod 6 drives first gear 7 to rotate, which in turn drives second gear 9 through meshing. Second gear 9 drives rotating sleeve 21 to rotate, which in turn drives movable sleeve 12 to rotate. Movable sleeve 12 then drives rotating disk 16 to rotate, which in turn drives sliding rod 18 to rotate. As sliding rod 18 passes protrusion 17, it moves upwards along the surface of protrusion 17. Meanwhile, locking block 19 engages with two springs 2... The corresponding compression and stretching are performed, and when the slide rod 18 leaves the protrusion 17, under the elastic force of the two springs 20, the slide rod 18, the rotating disk 16 and the movable sleeve 12 are reset, thereby causing the movable sleeve 12 to drive the stirring rod 13 to move, and at the same time, the liquid herbicide raw material discharged from the conveying port 15 is stirred and mixed. By moving the movable sleeve 12 up and down, it is ensured that the agents of different densities are quickly mixed in the entire tank, avoiding the discharge ratio error caused by stratification, which can accelerate the mixing, reduce the mixing time, maintain uniformity, and improve the efficiency and production efficiency of the device.

[0031] Working principle: For this type of automatic proportioning and mixing device for herbicide production, the operator first injects the liquid herbicide raw material into the proportioning tank 3. Then, the motor 4 is started, and the output end of the motor 4 drives the rotating rod 6 to rotate. At the same time, the rotating rod 6 drives the first gear 7 to rotate. Then, the first gear 7 drives the second gear 9 to rotate through meshing connection. At the same time, the second gear 9 drives the rotating sleeve 21 to rotate. Thus, the rotating sleeve 21 drives the movable sleeve 12 to rotate. Then, the movable sleeve 12 drives the stirring rod 13 to rotate and stir. At the same time, the rotating sleeve 21 drives the scraper 14 to rotate and scrape the inner wall of the mixing chamber 11. Through stirring and scraping the mixing chamber 11, the raw material is prevented from adhering to the inner wall and bottom, which affects the stirring. This ensures the proportioning accuracy and mixing uniformity, improves the equipment turnover rate, and achieves multiple optimizations of material mixing and anti-adhesion.

[0032] When the operator starts the motor 4, the output of the motor 4 drives the rotating rod 6 to rotate. At the same time, the rotating rod 6 drives the first gear 7 to rotate, which in turn drives the second gear 9 to rotate through meshing. The second gear 9 drives the rotating sleeve 21 to rotate, which in turn drives the movable sleeve 12 to rotate. The movable sleeve 12 then drives the rotating disk 16 to rotate, and the rotating disk 16 drives the sliding rod 18 to rotate. When the sliding rod 18 passes the protrusion 17, it moves upward along the surface of the protrusion 17. At the same time, the locking block 19 compresses and stretches the two springs 20 accordingly. When the sliding rod 18 leaves the protrusion 17, under the elastic force of the two springs 20, the sliding rod 18, the rotating disk 16, and the movable sleeve 12 return to their original positions. This causes the movable sleeve 12 to drive the stirring rod 13 to move, thereby stirring and mixing the liquid herbicide raw material discharged from the conveying port 15. By moving the movable sleeve 12 up and down, it ensures that the agents of different densities are quickly mixed throughout the entire tank, avoiding the discharge ratio error caused by stratification, accelerating the mixing process, and reducing the mixing time.
