[0002] In the pesticide production process, especially in the production of suspension pesticides, it is necessary to accurately and efficiently deliver the pesticide active ingredients to specific reaction containers or processing equipment.

[0003] Traditional feeding methods have many shortcomings. For example, gravity feeding can easily lead to uneven feeding of some highly viscous suspension pesticide technicals; while mechanical feeding has a complex equipment structure, high maintenance costs, and is prone to vibration and noise during operation, which affects the quality of pesticide raw materials and the working environment.

[0004] In addition, existing feeding devices have significant limitations in terms of compatibility and applicability. The height of their discharge end lacks a flexible adjustment mechanism, making it difficult to customize and adapt them according to the differences in the height of the feed end of different processing equipment in actual production. This results in a cumbersome and complicated docking process between the feeding operation and the processing equipment, which seriously reduces the convenience and efficiency of production operations.

[0005] Therefore, it is necessary to provide a pneumatic feeding device for suspension pesticide technical materials to solve the above-mentioned technical problems. Utility Model Content

[0029] Please see Figures 1-4 One embodiment provided by this utility model:

[0030] A pneumatic feeding device for suspension pesticide technical material, comprising:

[0031] The base 1 and the feeding bin 2 are provided. Several support legs 3 are fixedly installed on the lower side of the outer surface of the feeding bin 2, and the bottom end of the support legs 3 is fixedly connected to the top of the base 1. The top of the feeding bin 2 is provided with a cover plate 8. A feed pipe 9 is fixedly installed on one side of the top of the cover plate 8. A bracket 16 is fixedly installed on one side of the top of the base 1. A rotating shaft 17 is rotatably installed on the bracket 16. A feeding pipe 13 is fixedly installed on the rotating shaft 17.

[0032] A discharge pipe 22 is fixedly installed at the bottom of the feeding hopper 2. A connecting pipe 24 is fixedly connected between the bottom end of the discharge pipe 22 and the bottom end of the feeding pipe 13. A valve 21 is provided on the upper side of the discharge pipe 22, and an air amplifier 23 is provided on the lower side of the discharge pipe 22. An adjustment mechanism is provided between the feeding pipe 13 and the top of the base 1. Universal wheels 19 are symmetrically distributed and fixedly installed on both sides of the bottom of the base 1.

[0033] A stirring mechanism 5 is provided at the bottom of the cover plate 8. The stirring mechanism 5 includes a stirring shaft 6, and the top end of the stirring shaft 6 is rotatably connected to the bottom of the cover plate 8. Several stirring blades 11 are fixedly installed on the outer wall of the stirring shaft 6. A servo motor 10 is fixedly installed at the top of the cover plate 8, and the drive end of the servo motor 10 passes through the cover plate 8 and extends to the bottom of the cover plate 8 and is fixedly connected to the top end of the stirring shaft 6. Several pressure relief holes 20 are opened on the stirring blades 11. The pressure relief holes 20 can reduce the fluid resistance during stirring, reduce power loss, extend the equipment life, and facilitate material mixing. They allow the material to pass through the holes to form turbulence, thereby enhancing the stirring effect and uniformity.

[0034] In one embodiment, an upper annular fixing plate 7 is fixedly installed on the outer surface of the cover plate 8, and a lower annular fixing plate 4 is fixedly installed on the outer wall of the top of the feeding hopper 2. The lower annular fixing plate 4 and the upper annular fixing plate 7 are fixedly connected by several bolts and nuts, which makes the connection stable and easy to disassemble, and facilitates the cleaning and maintenance of the inside of the feeding hopper 2 and the stirring mechanism 5.

[0035] In one preferred embodiment, an electric flow valve 12 is provided on the discharge end of the feeding pipe 13, which can accurately control the material flow rate, ensure the accuracy and stability of material feeding during the production process, and improve production quality and efficiency.

[0036] In one embodiment, the adjustment mechanism includes a second support 18, which is fixedly installed on one side of the top of the base 1. A cylinder 15 is hinged to the second support 18, and a first support 14 is hinged to the drive end of the cylinder 15. The first support 14 is fixedly connected to the feeding pipe 13, so as to realize the flexible adjustment of the height of the feeding pipe 13, meet the feeding height requirements of different processing equipment, and have good adaptability.

[0037] In one preferred embodiment, the connecting pipe 24 is made of an elastic telescopic flexible hose, which can flexibly extend and deform as the height of the feeding pipe 13 is adjusted, avoiding bending or breakage when the position of the feeding pipe 13 is adjusted, and ensuring smooth material conveying.

[0038] The working principle of this utility model is as follows: All electrical components mentioned are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer for control. Existing publicly available power connection technologies are not detailed here. Parts not mentioned in this device are the same as or can be implemented using existing technologies. When using this pneumatic feeding device for suspension-type pesticide technical materials, the universal wheels 19 roll against the ground to move the device quickly and accurately to the designated side of the processing equipment. Subsequently, the control cylinder 15 starts operating. The extension and retraction of the drive end of the cylinder 15 drives the feeding pipe 13 to rotate around the pivot 17 via the first support 14, thereby achieving precise adjustment of the height of the discharge end of the feeding pipe 13. Based on the actual height of the feed end of the processing equipment, the position of the feeding pipe 13 is carefully adjusted. Then, utilizing the device's mobility, the discharge end of the feeding pipe 13 is moved to directly above the feed end of the processing equipment. At this time, the valve 21 is opened, and the air amplifier 23 starts working. After compressed air is connected, the air amplifier 23, based on aerodynamic principles, forms a stable vacuum negative pressure zone on one side, which can efficiently draw in the suspension-type pesticide technical material from the feeding hopper 2. On the other side, it generates a strong blowing and exhaust effect, providing sufficient power for material conveying and ensuring that the pesticide technical material can be smoothly conveyed upwards. Under the combined action of gravity and aerodynamics, the pesticide technical material is guided into the feeding pipe 13 through the connecting pipe 24, and finally accurately discharged into the designated processing equipment through the discharge end of the feeding pipe 13, efficiently completing the pneumatic feeding process of suspension-type pesticide technical material.

[0039] During the storage of suspension-type pesticide technical in the feeding hopper 2, the servo motor 10 can be activated. The servo motor 10, with its stable and precisely controlled power output, drives the stirring shaft 6 to rotate in a circular motion. The rotation of the stirring shaft 6 synchronously drives the connected stirring blades 11 to rotate around the axis of the stirring shaft 6. During rotation, the stirring blades 11 fully contact the pesticide technical in the feeding hopper 2, performing uniform and continuous stirring, effectively promoting the mixing and dispersion of different components within the pesticide technical, thereby significantly improving the uniformity of pesticide distribution within the feeding hopper 2 and ensuring the stable quality of the pesticide technical delivered during subsequent feeding processes.

[0040] During the use of the feeding hopper 2, its top cover 8 is installed on the top of the feeding hopper 2 via a detachable connection between the upper annular fixing plate 7 and the lower annular fixing plate 4. Specifically, this detachable connection is achieved using bolts and nuts. When cleaning and maintenance of the mixing mechanism 5 and the interior of the feeding hopper 2 are required, simply remove the bolts and nuts connecting the upper annular fixing plate 7 and the lower annular fixing plate 4 to easily remove the lower cover 8, thereby directly performing a comprehensive and meticulous cleaning and maintenance of the mixing mechanism 5 and the interior of the feeding hopper 2, fully demonstrating the high practicality of the structural design of the feeding hopper 2.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
