Description

Technical Field

[0001] This invention belongs to the technical field of herbicide production equipment, and relates to a stirring kettle for agricultural herbicide production. Background Technology

[0002] Herbicides are pesticides that can cause weeds to die completely or selectively. They are a class of substances used to kill or inhibit plant growth. Sodium chlorate, borax, arsenic, and trichloroacetic acid among them have a killing effect on any type of plant. Their effectiveness is affected by three factors: the herbicide, the plant, and environmental conditions. Based on their action, they are divided into non-selective and selective herbicides. Selective herbicides, especially derivatives of nitrophenol, chlorophenol, and carbamic acid, are mostly effective. The development of herbicides worldwide has gradually stabilized, with the main focus on developing highly efficient, low-toxicity, broad-spectrum, and low-dosage varieties. Single-use herbicides with low environmental pollution are gradually becoming the mainstream and are widely used in agriculture.

[0003] Currently, the production process of herbicides requires the raw materials to be stirred to ensure that the components are fully mixed. This stirring process requires the use of a mixing tank. However, existing mixing tanks used in herbicide production generate air bubbles when stirring the raw materials, which reduces the mixing effect of the raw materials and affects the efficacy of the herbicide. Summary of the Invention

[0004] The purpose of this invention is to provide a mixing tank for agricultural herbicide production, in order to solve the technical problem that existing mixing tanks for herbicide production generate air bubbles when stirring the raw materials, which reduces the mixing effect of the raw materials and affects the efficacy of the herbicide.

[0005] To achieve the above objectives, the specific technical solution of the stirred tank for agricultural herbicide production according to the present invention is as follows:

[0006] A mixing tank for producing agricultural herbicides, comprising:

[0007] The shell has a feeding port at the top and a discharge port on the side near the bottom;

[0008] The transmission rod is vertically installed inside the housing. Its lower end is rotatably connected to the bottom of the housing, and its upper end passes through the top of the housing and is connected to the drive assembly. The drive assembly is used to drive the transmission rod to rotate.

[0009] Multiple stirring blades are mounted on the drive rod and evenly distributed along the vertical direction;

[0010] The transmission ring is fitted onto the transmission rod and is located above the multiple stirring blades, and is movably connected to the transmission rod.

[0011] The first annular filter screen is sleeved on the outer side of the transmission ring, with its edge close to the inner wall of the housing and movably connected to the inner wall of the housing;

[0012] The transmission disc, sleeved on the transmission rod, is located between the multiple stirring blades and the transmission ring;

[0013] The vibration component is located inside the housing and is connected to the transmission disc, transmission ring, and first annular filter screen respectively. It is used to drive the transmission ring and the first annular filter screen to vibrate up and down through the transmission disc.

[0014] The invention is further characterized by:

[0015] The drive component includes a motor, which is located on the upper part of the housing near the upper end of the transmission rod. The output end of the motor is connected to the upper end of the transmission rod.

[0016] The vibration component includes a fixed ring, which is located inside the housing at the upper part of the first annular filter screen. A transmission rod is located inside the fixed ring, and the outer side of the fixed ring is connected to the inner wall of the housing. Multiple first elastic elements are vertically and evenly arranged between the fixed ring and the first annular filter screen. The two ends of each first elastic element are connected to the fixed ring and the first annular filter screen, respectively. A transmission disk is fixedly connected to the transmission rod. Two first guide blocks are symmetrically arranged on the upper surface of the transmission disk. Multiple second guide blocks are arranged on the lower part of the transmission ring near the two first guide blocks. The multiple second guide blocks are evenly arranged along the transmission ring, and the lower parts of the multiple second guide blocks are in contact with the upper surface of the transmission disk. Each first guide block is located between two of the second guide blocks. The two first guide blocks and the multiple second guide blocks are all hemispherical.

[0017] The inner diameter of the transmission ring is larger than the diameter of the transmission rod. The diameters of the two first guide blocks are different. A cylindrical filter screen is installed inside the housing at the lower part of the first annular filter screen. The transmission rod and multiple stirring blades are located inside the cylindrical filter screen. The upper part of the cylindrical filter screen is connected to the lower part of the first annular filter screen. A second annular filter screen is horizontally installed between two vertically adjacent stirring blades. The transmission rod is located inside the second annular filter screen. The edge of the second annular filter screen is connected to the inner wall of the cylindrical filter screen.

[0018] The casing contains two vertically symmetrical connecting plates positioned between the inner wall of the casing and the cylindrical filter screen. The outer surfaces of the two connecting plates contact the inner wall of the casing. Multiple arc-shaped scrapers are evenly distributed vertically between the two sides of the two connecting plates. Each arc-shaped scraper has its two ends connected to the sides of the two connecting plates, and its outer surface contacts the inner wall of the casing. An L-shaped connecting rod is provided between the upper end of each connecting plate and the first annular filter screen. One end of the L-shaped connecting rod is connected to the inner surface of the connecting plate, and the other end of the L-shaped connecting rod is provided with a mounting block between it and the first annular filter screen. The upper part of the mounting block is connected to the lower part of the first annular filter screen. A ball groove is formed on the lower surface of the mounting block, and a connecting ball is placed in the ball groove. The connecting ball passes through the lower opening of the ball groove and connects to the other end of the L-shaped connecting rod.

[0019] The inner wall of the housing has vertically formed a limiting cavity near the outer side of the two connecting plates. The inner wall of the housing has vertically formed a limiting groove near the two limiting cavities. The limiting groove is connected to the corresponding limiting cavity. A limiting rod is vertically set inside each limiting cavity. A second elastic element is vertically set at both ends of the limiting rod. The two ends of each second elastic element are connected to the end of the limiting rod and the end of the limiting cavity, respectively. A slider is set inside the limiting groove. The two ends of the slider are connected to the side of the limiting rod and the outer side of the connecting plate, respectively.

[0020] Multiple support blocks are evenly arranged at the lower part of the shell near the edge.

[0021] The bottom of the shell is a slope, and the lowest point of the slope is close to the discharge port.

[0022] The mixing tank for agricultural herbicide production of the present invention has the following advantages:

[0023] First, through the coordinated arrangement of the transmission rod, transmission ring, first annular filter screen, transmission disc and vibration component, the first annular filter screen can be driven to vibrate up and down. The up and down vibration of the first annular filter screen breaks up the air bubbles generated by the raw materials during stirring, improves the mixing effect of the raw materials and ensures the efficacy of the herbicide.

[0024] Secondly, by using two first guide blocks with different diameters and a combination of cylindrical filter screen and multiple second annular filter screens, it is possible to oscillate and stir each component raw material in the horizontal direction and vibrate and stir each component raw material in the vertical direction while breaking up air bubbles, thereby increasing the mixing effect of each component raw material and further ensuring the efficacy of the herbicide.

[0025] Third, through the coordinated arrangement of two L-shaped connecting rods, two connecting balls, two connecting plates, and multiple arc-shaped scrapers, multiple arc-shaped scrapers can be driven to move up and down along the inner wall of the shell, thereby cleaning the inner wall of the shell and preventing the raw materials of each component from sticking to the inner wall of the shell, thus further ensuring the efficacy of the herbicide.

[0035] To better understand the purpose, structure, and function of this invention, the following detailed description of a stirring tank for agricultural herbicide production is provided in conjunction with the accompanying drawings.

[0036] like Figure 1As shown, the present invention discloses a mixing tank for agricultural herbicide production, comprising a shell 1, a feeding port 15 at the upper part of the shell 1 for adding various component raw materials, a discharge port 16 near the bottom of the side of the shell 1, a transmission rod 2 vertically arranged inside the shell 1, the lower end of the transmission rod 2 being rotatably connected to the bottom of the shell 1, and the upper end of the transmission rod 2 passing through the top of the shell 1 and connected to a drive assembly for driving the transmission rod 2 to rotate, a plurality of stirring blades 4 being evenly arranged vertically on the transmission rod 2, a transmission ring 4 being sleeved on the transmission rod 2 above the plurality of stirring blades 4, the transmission ring 4 being movably connected to the transmission rod 2, and the transmission ring 4 being able to move up and down along the transmission rod 2, the outer side of the transmission ring 4 being sleeved with a first ring. A first annular filter screen 7 is fixedly connected to a transmission ring 4. The edge of the first annular filter screen 7 is close to the inner wall of the housing 1 and is movably connected to the inner wall of the housing 1 to facilitate the up and down movement of the first annular filter screen 7. A transmission disc 6 is sleeved on the transmission rod 2 at a position between multiple stirring blades 4 and the transmission ring 4. The transmission disc 6 is fixedly connected to the transmission rod 2. A vibration assembly is provided inside the housing 1. The vibration assembly is connected to the transmission disc 6, the transmission ring 4, and the first annular filter screen 7 respectively. The vibration assembly is used to drive the transmission ring 4 and the first annular filter screen 7 to vibrate up and down through the transmission disc 6. Thus, the up and down vibration of the first annular filter screen breaks up the air bubbles generated by the raw materials during stirring, improves the mixing effect of the raw materials, and ensures the efficacy of the herbicide.

[0037] The drive assembly includes a motor 3, which is located on the upper part of the housing 1 near the upper end of the transmission rod 2. The output end of the motor 3 is connected to the upper end of the transmission rod 2. When the motor 3 is started, the motor 3 drives the transmission rod 2 to rotate.

[0038] like Figure 1-6As shown, the system includes a fixed ring 12, which is located inside the housing 1 above the first annular filter screen 7. A transmission rod 2 is located inside the fixed ring 12. The outer surface of the fixed ring 12 is connected to the inner wall of the housing 1. Multiple first elastic elements 13 are vertically and evenly arranged between the fixed ring 12 and the first annular filter screen 7. Each first elastic element 13 has its two ends connected to the fixed ring 12 and the first annular filter screen 7, respectively, facilitating the reset of the first annular filter screen 7 after it moves upwards. A transmission disk 6 is fixedly connected to the transmission rod 2, which can drive the transmission disk 6 to rotate. Two first guide blocks 10 are symmetrically arranged on the upper surface of the transmission disk 6. Multiple second guide blocks 11 are arranged on the lower part of the transmission ring 4 near the two first guide blocks 10. The multiple second guide blocks 11 are evenly arranged along the transmission ring 4, and their lower parts contact the upper surface of the transmission disk 6. The first elastic element 13 ensures that the multiple second guide blocks 11 are always in contact with the surface of the transmission disk 6. Each first guide block 10 is located between two second guide blocks 11. Both the two first guide blocks 10 and the multiple second guide blocks 11 are hemispherical. When the transmission rod 2 rotates, it drives the transmission disk 6 to rotate. The transmission disk 6 drives the two first guide blocks 10 to rotate. When the two first guide blocks 10 pass each second guide block 11, they lift it up. The multiple second guide blocks 11 drive the transmission ring 4 to move upward. The transmission ring 4 drives the first annular filter screen 7 to move upward. The first annular filter screen 7 squeezes the multiple first elastic elements 13 to contract it. After the two first guide blocks 10 pass each second guide block 11, the first annular filter screen 7 moves downward under its own weight and the elastic force of the multiple first elastic elements 13. This process is repeated, vibrating up and down continuously, breaking up the air bubbles generated when the raw materials are stirred.

[0039] like Figure 1 , 2As shown, the inner diameter of the transmission ring 4 is larger than the diameter of the transmission rod 2. The diameters of the two first guide blocks 10 are different, so that the distance the two sides move is different each time the transmission ring 4 moves upward. This causes the transmission ring 4 to tilt after each up-and-down movement. A cylindrical filter 9 is set inside the housing 1 at the lower part of the first annular filter 7. The transmission rod 2 and multiple stirring blades 4 are located inside the cylindrical filter 9. The upper part of the cylindrical filter 9 is connected to the lower part of the first annular filter 7. A second annular filter 8 is horizontally set between two vertically adjacent stirring blades 4. The transmission rod 2 is located inside the second annular filter 8. The edge of the second annular filter 8 is connected to the inner wall of the cylindrical filter 9. When the transmission ring 4 drives the first annular filter 7 to vibrate up and down and swing left and right, the first annular filter 7 drives the cylindrical filter 9 and multiple second annular filter 8 to vibrate up and down and swing left and right. While breaking up air bubbles, the raw materials are swung and stirred horizontally and vertically, increasing the mixing effect of the raw materials and further ensuring the efficacy of the herbicide.

[0040] like Figure 1 , 3 As shown, two vertically symmetrical connecting plates 25 are arranged inside the housing 1, between the inner wall of the housing 1 and the cylindrical filter screen 9. The outer sides of the two connecting plates 25 contact the inner wall of the housing 1, allowing the connecting plates 25 to move freely up and down along the inner wall of the housing 1. Multiple arc-shaped scrapers 26 are evenly arranged vertically between the two sides of the two connecting plates 25. The two ends of each arc-shaped scraper 26 are connected to the sides of the two connecting plates 25, and the outer side of each arc-shaped scraper 26 contacts the inner wall of the housing 1. The arc-shaped scrapers 26 can move freely up and down along the inner wall of the housing 1. The inner side of each arc-shaped scraper 26 is inclined, and the lower part is tilted towards the transmission rod 2, reducing the contact area between the upper part of the arc-shaped scraper 26 and the inner wall of the housing 1, thus improving the cleaning effect. An L-shaped connecting rod 20 is provided between the upper end of each connecting plate 25 and the first annular filter screen 7. One end of the connecting rod 20 is connected to the inner side of the connecting plate 25. The other end of the L-shaped connecting rod 20 is connected to the first annular filter screen 7 by a mounting block 17. The upper part of the mounting block 17 is connected to the lower part of the first annular filter screen 7. A ball groove 18 is opened on the lower surface of the mounting block 17. A connecting ball 19 is set in the ball groove 18. The connecting ball 19 can rotate freely inside the ball groove 18. After passing through the lower opening of the ball groove 18, part of the connecting ball 19 is connected to the other end of the L-shaped connecting rod 20, ensuring that the first annular filter screen 7 can tilt when it vibrates up and down. When the first annular filter screen 7 vibrates up and down, the two L-shaped connecting rods 20 drive the two connecting plates 25 to move up and down. The two connecting plates 25 drive multiple arc-shaped scrapers 26 to move up and down along the inner wall of the shell 1, thereby cleaning the inner wall of the shell 1 and preventing the raw materials of each component from sticking to the inner wall of the shell 1, further ensuring the efficacy of the herbicide.

[0041] like Figure 1 , 7 As shown, a limiting cavity 21 is vertically formed on the inner wall of the housing 1 near the outer side of the two connecting plates 25. A limiting groove 22 is vertically formed on the inner wall of the housing 1 near the two limiting cavities 21. The limiting groove 22 is connected to the corresponding limiting cavity 21. A limiting rod 23 is vertically arranged inside each limiting cavity 21. The limiting rod 23 can move up and down within the limiting cavity 21. A second elastic element 14 is vertically arranged at both ends of the limiting rod 23. The two ends of each second elastic element 14 are connected to the end of the limiting rod 23 and the end of the limiting cavity 21, respectively. A slider 24 is arranged in the limiting groove 22. The slider 24 can move up and down along the limiting groove 22. The two ends of the slider 24 are connected to the side of the limiting rod 23 and the outer side of the connecting plate 25, respectively. The length of the limiting groove 22 is less than the length of the connecting plate 25, and the connecting plate 25 can completely cover the limiting groove 22 to prevent the raw materials of each component from entering the limiting cavity 21.

[0042] Multiple support blocks 27 are evenly arranged at the lower part of the shell 1 near the edge.

[0043] like Figure 1 As shown, the bottom of the shell 1 is a slope, and the lowest point of the slope at the bottom of the shell 1 is close to the discharge port 16, ensuring that the raw materials of each component after mixing flow from the slope to the discharge port 16 and out of the discharge port 16. A valve is provided on the discharge port 16.

[0044] Working principle: When in use, start the motor 3, and feed each component raw material into the housing 1 through the feeding port 15. The motor 3 drives the transmission rod 2 to rotate, which in turn drives multiple stirring blades 4 to rotate and stir the raw materials. At the same time, the transmission rod 2 drives the transmission disk 6 to rotate, which in turn drives two first guide blocks 10 to rotate. When the two first guide blocks 10 pass each second guide block 11, they lift it up. The multiple second guide blocks 11 drive the transmission ring 4 to move upward, which in turn drives the first annular filter screen 7 to move upward. The first annular filter screen 7 compresses multiple first elastic elements 13 to make it contract. After the two first guide blocks 10 pass each second guide block 11, the first annular filter screen 7 moves downward under its own weight and the elastic force of the multiple first elastic elements 13. This process repeats continuously, vibrating up and down, breaking up the air bubbles generated during the stirring of each component raw material.

[0045] Furthermore, while the transmission ring 4 drives the first annular filter screen 7 to vibrate up and down continuously and swing left and right, the first annular filter screen 7 drives the cylindrical filter screen 9 and multiple second annular filter screens 8 to vibrate up and down and swing left and right. While breaking up air bubbles, the components are swung and stirred in the horizontal direction and vibrated and stirred in the vertical direction, thereby increasing the mixing effect of the components.

[0046] Furthermore, when the first annular filter screen 7 vibrates up and down, the two L-shaped connecting rods 20 drive the two connecting plates 25 to move up and down. The two connecting plates 25 drive multiple arc-shaped scrapers 26 to move up and down along the inner wall of the housing 1, thereby cleaning the inner wall of the housing 1 and preventing the raw materials of each component from sticking to the inner wall of the housing 1.

[0047] The mixing tank for agricultural herbicide production of the present invention has the following advantages:

[0048] First, through the coordinated arrangement of the transmission rod, transmission ring, first annular filter screen, transmission disc and vibration component, the first annular filter screen can be driven to vibrate up and down. The up and down vibration of the first annular filter screen breaks up the air bubbles generated by the raw materials during stirring, improves the mixing effect of the raw materials and ensures the efficacy of the herbicide.

[0049] Secondly, by using two first guide blocks with different diameters and a combination of cylindrical filter screen and multiple second annular filter screens, it is possible to oscillate and stir each component raw material in the horizontal direction and vibrate and stir each component raw material in the vertical direction while breaking up air bubbles, thereby increasing the mixing effect of each component raw material and further ensuring the efficacy of the herbicide.

[0050] Third, through the coordinated arrangement of two L-shaped connecting rods, two connecting balls, two connecting plates, and multiple arc-shaped scrapers, multiple arc-shaped scrapers can be driven to move up and down along the inner wall of the shell, thereby cleaning the inner wall of the shell and preventing the raw materials of each component from sticking to the inner wall of the shell, thus further ensuring the efficacy of the herbicide.

Furthermore, under the teachings of the present invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the invention.
