Description

Technical Field

[0001] This utility model relates to the field of fertilizer production technology, and in particular to a pellet forming device for a rotary drum granulator used in fertilizer production. Background Technology

[0002] Fertilizer is a material that provides the nutrients needed for plant growth and development. It can improve soil properties and increase soil fertility, thereby promoting increased crop yields and income. It is an indispensable and important material in agricultural production. In the fertilizer production process, in order to facilitate storage, transportation and application, it is usually necessary to process powdered or lumpy fertilizer raw materials into granules. The granulation device of the drum granulator is the key equipment to realize this transformation. The device mainly consists of an inclined drum body, a feeding mechanism, a transmission mechanism, etc. When working, the fertilizer raw materials enter the drum. As the drum rotates, the raw materials gradually agglomerate and roll into granules with a certain particle size and strength under the action of their own gravity, friction, and a certain humidity and temperature.

[0003] The tilt angle of the drum in existing fertilizer pellet forming devices is mostly fixed, which cannot be flexibly adjusted according to the characteristics of different fertilizer raw materials and pellet forming requirements. When parameters such as raw material moisture and viscosity change, problems such as excessively large or small pellets and low forming rate are likely to occur. At the same time, existing devices lack an effective stirring structure. Fertilizer raw materials rotate in the same direction as the drum, resulting in insufficient mixing and uneven nutrient distribution in the produced granulated fertilizer, leading to poor quality stability. Utility Model Content

It can flexibly adjust the angle of the drum to adapt to different raw material characteristics and can achieve full mixing of raw materials, ensuring granulation effect and quality stability, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a granulation device for a rotary granulator for fertilizer production, comprising a rotary drum body, transmission supports being provided on both the left and right sides of the outer surface of the rotary drum body, a fixed base being movably hinged to the bottom end of the right transmission support, an adjusting base being movably hinged to the bottom end of the left transmission support, and a stirring assembly being fixedly connected to the left side of the left transmission support.

[0006] The adjusting base includes a connecting seat. Connecting grooves are provided on both the front and rear sides of the top of the connecting seat. A guide post is fixedly connected to the middle of the connecting groove. A sliding block is slidably connected to the outer surface of the guide post. A support bracket is fixedly connected to the top of the two sliding blocks. A bidirectional screw is rotatably connected to the inner side of the support bracket. The front and rear ends of the bidirectional screw pass through the front and rear sides of the support bracket and are fixedly connected to knobs. Threaded sliders are threadedly connected to the front and rear sides of the outer surface of the bidirectional screw. The outer surface of the threaded slider is slidably connected to the inner surface of the support bracket. A push rod is hinged to the top of the threaded slider. A lifting plate is hinged to the top of the two push rods. The lifting plate is movably hinged to the bottom of the left-side transmission bracket.

[0007] Preferably, the transmission support includes a transmission gear ring, which is fixedly connected to the outer surface of the roller body. An annular bracket is provided on the outer surface of the transmission gear ring, and the inner surface of the annular bracket is rotatably connected to the outer surface of the roller body.

[0008] Preferably, a drive motor is fixedly connected to the side of the annular bracket, and the output shaft of the drive motor passes through the inner side of the annular bracket and is fixedly connected to a rotating wheel. The outer surface of the rotating wheel meshes with the outer surface of the transmission gear ring.

[0009] Preferably, the stirring assembly includes a fixing plate, which is rotatably connected to the left side of the inner surface of the drum body. A U-shaped fixing frame is fixedly connected to the left side of the fixing plate, and the U-shaped fixing frame is fixedly connected to the left surface of the left transmission bracket. A feed inlet is provided at the top of the fixing plate.

[0010] Preferably, a transmission wheel three is rotatably connected to the middle left side of the fixed plate, and the right end of the transmission wheel three extends through to the right side of the fixed plate and is fixedly connected to a rotating frame. Arc-shaped stirring rods are fixedly connected to both the front and rear ends of the rotating frame.

[0011] Preferably, a second transmission wheel is meshed with the bottom of the outer surface of the third transmission wheel, the second transmission wheel is rotatably connected to the left side of the fixed plate, and a second transmission gear ring is meshed with the bottom of the outer surface of the second transmission wheel, the second transmission gear ring is fixedly connected to the left end of the inner surface of the roller body.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1. In this utility model, the flexible adjustment of the roller angle is achieved through the cooperation of the knob, the bidirectional screw, the threaded slider, the push rod, the lifting plate, the sliding block, and the connecting groove. The principle is that rotating the knob drives the bidirectional screw to rotate, causing the threaded slider to slide along the support bracket. The push rod then drives the lifting plate to move up and down, thereby causing the left side of the roller to swing up and down to change the inclination angle. At the same time, the sliding block can slide left and right along the guide column in the connecting groove, allowing the support bracket and the lifting plate to adapt to the displacement during the adjustment process and avoid motion interference.

[0013] 2. In this utility model, the reverse mixing of raw materials is achieved through the cooperation between the drum body, the second transmission gear ring, the second transmission wheel, the third transmission wheel, the rotating frame, and the arc-shaped stirring rod. The principle is that when the drum body rotates, it drives the second transmission gear ring to rotate synchronously. The second transmission gear ring drives the second transmission wheel to rotate through meshing. The second transmission wheel then drives the third transmission wheel to rotate, which in turn causes the rotating frame to drive the arc-shaped stirring rod to rotate in the opposite direction to the drum body. The beneficial effect of this structure is that it can break the inertia of the raw materials rotating in the same direction as the drum. By reversing the mixing, it enhances the frequency of tumbling and collision of the raw materials, so that the raw materials in different areas are fully mixed, ensuring that the nutrients in the granular fertilizer are evenly distributed and improving the product quality.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1: As Figure 1 and Figure 3 As shown, this utility model provides a technical solution: it includes a drum body 1, with transmission brackets 2 on both the left and right sides of the outer surface of the drum body 1. A fixed base 3 is movably hinged to the bottom end of the right transmission bracket 2, and an adjusting base 4 is movably hinged to the bottom end of the left transmission bracket 2. A stirring assembly 5 is fixedly connected to the left side of the left transmission bracket 2.

A guide post 43 is fixedly connected to the middle of the connecting groove 42, and sliding blocks 44 are slidably connected to the outer surface of the guide post 43. Two sliding blocks 44... A support bracket 45 is fixedly connected to the top of the support bracket 45. A double-acting screw 46 is rotatably connected to the inner side of the support bracket 45. The front and rear ends of the double-acting screw 46 pass through the front and rear sides of the support bracket 45 respectively and are fixedly connected to knobs 47. Threaded sliders 48 are threadedly connected to the front and rear sides of the outer surface of the double-acting screw 46. The outer surface of the threaded slider 48 is slidably connected to the inner surface of the support bracket 45. A push rod 49 is hinged to the top of the threaded slider 48. A lifting plate 410 is hinged to the top of the two push rods 49. The lifting plate 410 is movably hinged to the bottom of the left transmission bracket 2. The overall effect of Embodiment 1 is as follows: By adjusting the coordinated action of the various components of the base 4, the tilt angle of the roller body 1 is precisely and stably adjusted. When the knob 47 is turned, the bidirectional screw 46 rotates, driving the two threaded sliders 48 to move in opposite directions along the support bracket 45, thereby causing the push rod 49 to push the lifting plate 410 up or down, realizing the up and down swing of the left side of the roller body 1, thereby changing the overall tilt angle of the roller body 1. At the same time, during the adjustment process, the sliding block 44 slides along the guide column 43 in the connecting groove 42, so that the support bracket 45 and the lifting plate 410 can adaptively move left and right with the swing of the roller body 1, effectively avoiding motion interference between components, ensuring the smoothness and stability of the adjustment process, providing suitable tilt angle conditions for the roller body 1 for fertilizer raw materials with different characteristics, and helping to improve the quality of pellet forming.

[0019] Example 2: Figure 2 and Figure 4As shown, this utility model provides a technical solution: the transmission support 2 includes a transmission gear ring 21, which is fixedly connected to the outer surface of the drum body 1. An annular bracket 22 is provided on the outer surface of the transmission gear ring 21. The inner surface of the annular bracket 22 is rotatably connected to the outer surface of the drum body 1. A drive motor 23 is fixedly connected to the side of the annular bracket 22. The output shaft of the drive motor 23 passes through the inner side of the annular bracket 22 and is fixedly connected to a rotating wheel 24. The outer surface of the rotating wheel 24 meshes with the outer surface of the transmission gear ring 21. The stirring assembly 5 includes a fixing plate 5. 1. A fixed plate 51 is rotatably connected to the left side of the inner surface of the drum body 1. A U-shaped fixing frame 52 is fixedly connected to the left side of the fixed plate 51. The U-shaped fixing frame 52 is fixedly connected to the left surface of the left transmission bracket 2. A feed inlet 53 is provided at the top of the fixed plate 51. A transmission wheel 3 56 is rotatably connected to the middle of the left side of the fixed plate 51. The right end of the transmission wheel 3 56 extends through to the right side of the fixed plate 51 and is fixedly connected to a rotating frame 57. Arc-shaped stirring rods 58 are fixedly connected to both the front and rear ends of the rotating frame 57. A transmission wheel 2 55 is meshed with the bottom of the outer surface of the transmission wheel 3 56. 5. Rotary connection is made to the left side of the fixed plate 51. The bottom of the outer surface of the transmission wheel 2 55 is meshed with the transmission gear ring 2 54, which is fixedly connected to the left end of the inner surface of the drum body 1. The effect achieved by the entire embodiment 2 is as follows: the transmission bracket 2 provides stable support and power transmission for the rotation of the drum body 1. When the drive motor 23 is working, its output shaft drives the rotating wheel 24 to rotate. The rotating wheel 24 meshes with the transmission gear ring 21, thereby driving the drum body 1 to rotate stably around its own axis, providing basic motion conditions for the granulation of fertilizer raw materials. The mixing component 5 then implements... This invention enables highly efficient reverse mixing of fertilizer raw materials. When the drum body 1 rotates, the transmission gear ring 2 54 rotates accordingly. Through meshing with the transmission wheel 2 55, the transmission wheel 2 55 rotates. The transmission wheel 2 55 then meshes with the transmission wheel 3 56, causing the transmission wheel 3 56 to rotate. This, in turn, drives the rotating frame 57 and the arc-shaped stirring rod 58 to rotate in the opposite direction to the drum body 1. The reverse rotation of the arc-shaped stirring rod 58 can fully tumble and mix the fertilizer raw materials in the drum body 1, breaking the inertial motion of the raw materials in the same direction, making the raw materials more uniformly mixed, ensuring consistent nutrient distribution in the granular fertilizer, and improving product quality.

[0020] The working principle of the entire equipment is as follows: Before starting the equipment, according to the characteristics of the fertilizer raw material to be processed, the tilt angle of the roller body 1 is adjusted by adjusting the base 4. The operator turns the knob 47, the double screw 46 rotates, causing the two threaded sliders 48 to slide in the support bracket 45. The push rod 49 then drives the lifting plate 410 to rise or fall, causing the left side of the roller body 1 to swing up and down. At the same time, the sliding block 44 slides along the guide column 43 in the connecting groove 42, realizing the adaptive displacement of the support bracket 45 and the lifting plate 410, and completing the tilt angle adjustment of the roller body 1. After the adjustment is completed, the fertilizer raw material is put into the roller body 1 from the feed port 53 at the top of the fixed plate 51. Then the drive motor 23 is started. The output shaft of the drive motor 23 drives the rotating wheel 24 to rotate. The rotating wheel 24 meshes with the transmission gear ring 21, thereby driving the roller body 1 to rotate around its own axis. During the process, the fertilizer raw materials inside continuously roll and agglomerate under the action of gravity and friction. At the same time, the rotation of the drum 1 drives the transmission gear ring 54 fixed on the left end of its inner surface to rotate synchronously. The transmission gear ring 54 meshes with the transmission wheel 55, causing the transmission wheel 55 to rotate. The transmission wheel 55 meshes with the transmission wheel 56, causing the transmission wheel 56 to rotate. This causes the rotating frame 57 to drive the arc-shaped stirring rod 58 to rotate in the opposite direction to the drum 1. The reverse rotation of the arc-shaped stirring rod 58 fully stirs the fertilizer raw materials inside the drum 1, breaking the inertia of the same-direction movement of the raw materials, enhancing the tumbling and collision of the raw materials, and making the raw materials more uniformly mixed. Under the combined action of the rotation of the drum 1 and the reverse stirring of the arc-shaped stirring rod 58, the fertilizer raw materials gradually agglomerate and roll into granules with a certain particle size and strength, and finally discharge from the discharge end of the drum 1, completing the granulation process.
