Description

Technical Field

[0001] This utility model relates to the field of pesticide production equipment technology, and in particular to a granulation device for pesticide production. Background Technology

[0002] In the field of pesticide production, granulation is a crucial step, and its quality directly affects the pesticide's effectiveness, storage stability, and subsequent processing performance. With the advancement of agricultural modernization, the requirements for pesticide product quality and production efficiency are increasing, and traditional pesticide granulation equipment is gradually revealing many shortcomings.

[0003] Because pesticides have complex and diverse compositions, including active ingredients and excipients, their physicochemical properties vary. Uneven mixing can lead to significant differences in properties throughout the granulation process, affecting the consistency of the final granules. This can result in uneven pesticide release during application, reducing control efficacy, and even causing adverse effects on crops or rendering pests and diseases ineffective due to excessively high or low local concentrations. Furthermore, the lack of effective pressing and discharge control mechanisms during material forming is a major drawback of traditional equipment. Without proper pressing, inconsistent material density during forming makes stable forming difficult and prone to breakage. Problems such as irregular shapes and uneven discharge, coupled with the inability to adjust the direction of material flow, can lead to material accumulation during production, affecting efficiency and increasing manual intervention costs. Furthermore, prolonged material retention within the device can compromise quality stability. Additionally, due to the stickiness and uneven particle size distribution of pesticides, they easily adhere and accumulate as they pass through the sieve. Blockage not only interrupts the granulation process and reduces efficiency but also leads to prolonged downtime for maintenance due to cleaning difficulties, increasing both production and time costs. This severely impacts the large-scale production of pesticides. Traditional granulation devices are prone to material blockage at the sieve.

[0004] In summary, in order to overcome the shortcomings of traditional pesticide granulation devices in terms of mixing, molding, discharge and sieve plate treatment, this utility model proposes a granulation device for pesticide production.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Reference Figure 1-4 A granulation device for pesticide production includes a shell 1, a discharge assembly, a motor 21, a rotating shaft 2, a sieve plate 12, multiple arc-shaped plates 41 and multiple arc-shaped plates 42. Multiple feed pipes 11 are fixedly installed on the top of the shell 1. The motor 21 is fixedly installed at the center of the top of the shell 1. The sieve plate 12 and multiple arc-shaped plates 41 are fixedly installed on the inner side wall of the shell 1. The rotating shaft 2 is rotatably installed inside the sieve plate 12 and the shell 1, and the top of the rotating shaft 2 is axially fixedly connected to the output shaft of the motor 21. Multiple stirring rods 22 are radially fixedly installed on the outer side of the rotating shaft 2. Multiple arc-shaped openings are provided on the inner side wall of the shell 1. Multiple arc-shaped plates 42 are detachably installed in the corresponding arc-shaped openings and are adapted to the multiple arc-shaped plates 41. Multiple through holes are provided on the arc-shaped plates 42.

[0029] A strip plate 3 is radially fixedly installed on the rotating shaft 2. Two rotating rods 31 parallel to the rotating shaft 2 are rotatably installed on the strip plate 3. A stirring rod 32 is radially fixedly installed on each of the two rotating rods 31. The multiple stirring rods 32 are staggered with the corresponding stirring rods 22. When the rotating shaft 2 rotates, the rotating rods 31 can drive the stirring rods 32 to rotate around the rotating shaft 2, thereby quickly and evenly mixing the pesticide materials. Gears 34 are fixedly sleeved at the top of each of the two rotating rods 31. A toothed disc 33 is fixedly installed on the top inner wall of the housing 1. The two gears 34 mesh with the toothed disc 33, which can achieve a rapid self-rotation effect while the rotating rods 31 rotate around the rotating shaft 2. Multiple pressure rollers 4 are adapted to the arc plate 41 and the arc plate 42, and can perform a pressing operation on the material falling on the arc plate 41 and the arc plate 42, so that it can be shaped after passing through the through hole.

[0030] A second scraper 5 is fixedly installed on the rotating shaft 2. The top side of the second scraper 5 is adapted to the bottom side of the first arc plate 41 and the second arc plate 42. A third scraper 51 is fixedly installed at the lowest point of the second scraper 5. The bottom side of the third scraper 51 contacts the top side of the first guide plate 13. This allows for the cutting of pesticide particles passing through the through holes, while preventing pesticide residue from adhering to the bottom sides of the first arc plate 41 and the second arc plate 42. Furthermore, the third scraper 51 can move the already formed pesticide granules on the first guide plate 13, preventing material accumulation that could affect the pesticide particles on the second guide plate 14. Under normal material flow conditions, a guide plate 13 is fixedly installed on the inner wall of the shell 1. Multiple support rods are fixedly installed on the top side of the guide plate 13, and the same guide plate 14 is fixedly installed on the multiple support rods. The top sides of the guide plate 13 and the guide plate 14 are respectively convex and concave. A discharge pipe 131 is damped and rotatably installed at the bottom center of the shell 1, and the discharge pipe 131 extends into the shell 1 and is sealed and rotatably connected to the guide plate at the center. This allows for the guiding and discharge of the formed pesticide granules, and also facilitates the adjustment of the discharge direction as needed.

[0031] In this embodiment, in order to avoid the situation where material accumulation on the screen plate 12 affects normal screening, and at the same time to ensure that the material can pass through the screen plate 12 efficiently, the bottom ends of the rotating shaft 2 and the two rotating rods 31 are radially rotatably equipped with the same scraper 23, and the bottom side of the scraper 23 is in contact with the top side of the screen plate 12.

[0032] In this embodiment, in order to facilitate the fixing and disassembly of the second arc plate 42, the outer peripheral surface of the second arc plate 42 extends to the outside of the housing 1 and is fixedly installed with the third arc plate 43. The inner arc surface of the third arc plate 43 moves against the outer peripheral side of the housing 1, and the third arc plate 43 is fixedly connected to the housing 1 by bolts.

[0033] In this embodiment, to prevent pesticides from falling directly onto the guide plate 2 14 or guide plate 13 without passing through the through holes, the sum of the arc of the multiple arc plates 1 41 and the arc of the multiple arc plates 2 42 is 360 degrees.

[0034] The circuits, electronic components, and module mechanisms involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need no further explanation. The content protected by this application does not involve any improvement to the software, circuits, or methods.

[0035] Working Principle: In operation, the power is first switched on and the motor 21 is started. The pesticide material to be granulated is introduced into the housing 1 through the feed pipe 11. The motor 21 controls the rotation of multiple stirring rods 22 via the rotating shaft 2. Simultaneously, the strip plate 3 drives two rotating rods 31 to revolve around the rotating shaft 2. Due to the gears 34 and the gear disc 33, the rotating rods 31 can achieve rapid self-rotation while revolving around the rotating shaft 2, thus controlling the multiple stirring rods 32 to work in conjunction with the stirring rods 22 to quickly and evenly mix the pesticide material. During the mixing process, the scraper 23 scrapes the pesticide material on the sieve plate 12, facilitating the sieving of the evenly mixed pesticide material. After passing through the sieve plate 12, the pesticide material is compacted by the multiple pressure rollers 4 driven by the rotating shaft 2 and extruded through the through holes. The rotation of the rotating shaft 2 also drives the scraper 5 to press against the arc plate 42 and the arc plate 41. The bottom side is scraped to ensure that the pesticide material after being extruded through the through hole is cut off, thereby improving the uniformity of the pesticide particles to a certain extent. Then, the particles fall onto the guide plate 2 14. Since the top side of the guide plate 2 14 is convex, the pesticide particles move towards the inner wall of the shell 1 and fall down onto the guide plate 1 13. The top side of the guide plate 1 13 is concave, which can guide the pesticide particles towards the discharge pipe 131. At the same time, the scraper 2 5 also drives the scraper 3 51 to push the material on the guide plate 1 13, thereby preventing the accumulation of material on the guide plate 1 13 and the guide plate 2 14 near the inner wall of the shell 1. Since the discharge pipe 131 is damped and rotated and installed in the center of the bottom of the shell 1, the operator can also adjust the direction of the discharge according to the actual discharge needs.

Specific embodiments have been used to illustrate the principle and implementation of this utility model. The description of the embodiments above is only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
