Description

Technical Field

[0001] This utility model relates to the field of pesticide production technology, and in particular to a disc granulator for preparing pesticide granules. Background Technology

[0002] With the continuous development of pesticide formulations, pesticide granules, as the mainstream form of solid formulations, are increasingly being used in agricultural production. During the preparation of pesticide granules, the uniformity of the particles, particle size distribution, and pelleting rate directly affect the release rate of the active ingredient and the field application effect. Disc granulators, as a common type of granulation equipment, are widely used in the compound fertilizer field due to their advantages of continuous production and controllable particle size, and are gradually being applied in the production of other granules.

[0003] A search revealed Chinese Patent Publication No. CN216630714U, which discloses a disc granulator for preparing granules. The granulator includes a base, a granulation disc, a top cover, and a scraping mechanism. A transmission box is fixedly mounted on the base, housing a drive gear and a driven gear. The granulation disc is mounted on the shaft of the driven gear. The granulation disc is divided into disc body I and disc body II, which are sealed at their ends and locked together by snap fasteners. The top cover is fastened to the granulation disc and has a feed inlet. The scraping mechanism includes a mounting frame, a scraper frame, and a scraper plate. The mounting frame is fixedly mounted on the base, the scraper frame is fixedly mounted on the mounting frame and passes through the top cover, and the scraper plate is fixedly mounted at the lower end of the scraper frame. This invention provides a simple structure, saves time and effort in operation, does not cause dust pollution, and ensures clean and thorough material discharge without spillage.

[0004] In existing technologies, disc granulators typically employ a fixed tilt angle design. This design results in uneven particle distribution during the granulation process, leading to unsatisfactory particle formation. Especially when processing materials with high viscosity or high moisture content, the fixed tilt angle often fails to effectively accommodate the different angles of repose (critical angles for material sliding), resulting in uneven particle formation, low pelletizing rate, and even particle sticking to the wall, thus affecting the quality of the granules produced. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a disc granulator for preparing pesticide granules, aiming to improve the problem that a fixed angle is difficult to adapt to the angle of repose of different materials, which easily affects the quality of the product.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A disc granulator for preparing pesticide granules includes a base plate, a fixed plate fixedly connected to the upper surface of the base plate, a connecting column rotatably connected to the inner wall of the fixed plate, a support frame fixedly connected to the outer wall of the connecting column, a U-shaped block fixedly connected to the upper surface of the base plate, a hydraulic cylinder rotatably connected to the inner wall of the U-shaped block, a rotating block fixedly connected to the output end of the hydraulic cylinder, a support column rotatably connected to the inner wall of the rotating block, support plates fixedly connected to both outer walls of the support column, the upper surface of the support plate fixedly connected to the lower surface of the support frame, and a drive assembly provided on the lower surface of the support frame.

[0008] The above technical solution works as follows: when the hydraulic cylinder is activated, it pushes the rotating block to slide while rotating on the outer wall of the support column, thereby pushing the support column to slide. The sliding of the support column will then drive the support plate to slide, and finally, the support plate will drive the support frame and connecting column to rotate on the inner wall of the fixed plate, thus achieving the effect of adjusting the angle.

[0009] As a further description of the above technical solution:

[0010] The drive assembly includes a motor, the outer wall of which is fixedly connected to the lower surface of the support frame, and a rotating column is fixedly provided at the output end of the motor, with a gear fixedly connected to the outer wall of the rotating column.

[0011] Through the above technical solution: the motor can drive the rotating column to rotate, and the rotation of the rotating column will drive the gear to rotate.

[0012] As a further description of the above technical solution:

[0013] The gear teeth are meshed with a toothed disc, and a fixed column is rotatably connected to the inner wall of the toothed disc.

[0014] The above technical solution works by rotating the gears, which in turn drives the gear disc to rotate, and the fixed column provides support for the gear disc.

[0015] As a further description of the above technical solution:

[0016] The bottom end of the fixed column is fixedly connected to the upper surface of the support frame, and the upper surface of the toothed disc is fixedly connected to the disc body.

[0017] Through the above technical solution, the support frame can provide fixed support for the fixed column, and the rotation of the gear plate will drive the disc body to rotate.

[0018] As a further description of the above technical solution:

[0019] The outer wall of the support frame is fixedly connected to a bracket, and the outer wall of the bracket is fixedly connected to a fixing frame.

[0020] Through the above technical solution: the support frame can provide fixed support for the bracket, and the bracket can also provide fixed support for the fixed frame.

[0021] As a further description of the above technical solution:

[0022] A spring is fixedly connected to the inner wall of the fixed frame, and a sliding plate is provided at the bottom end of the spring. The outer wall of the sliding plate is slidably connected to the inner wall of the fixed frame.

[0023] Through the above technical solution, the fixed frame can support the spring, and the spring allows the sliding plate to slide upward elastically, achieving an elastic buffering effect.

[0024] As a further description of the above technical solution:

[0025] Spring 2 is fixedly connected to both outer walls of the sliding plate, and the outer wall of spring 2 is fixedly connected to the inner wall of the fixed frame.

[0026] Through the above technical solution: the fixed frame can provide fixed support for the second spring, and the second spring can buffer the sliding plate to the left and right sides.

[0027] As a further description of the above technical solution:

[0028] A connecting plate is fixedly connected to the lower surface of the sliding plate, and a scraper is fixedly connected to the lower surface of the connecting plate.

[0029] Through the above technical solution, the sliding plate can play a role in fixing and supporting the connecting plate, thereby supporting the scraper, and the buffering effect of the sliding plate will also buffer the scraper.

[0039] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0040] Reference Figure 1 and Figure 2 An embodiment of this utility model is provided: a disc granulator for preparing pesticide granules, including a base plate 1, a fixed plate 2 fixedly connected to the upper surface of the base plate 1, a connecting column 3 rotatably connected to the inner wall of the fixed plate 2, a support frame 4 fixedly connected to the outer wall of the connecting column 3, a U-shaped block 5 fixedly connected to the upper surface of the base plate 1, a hydraulic cylinder 6 rotatably connected to the inner wall of the U-shaped block 5, a rotating block 7 fixedly connected to the output end of the hydraulic cylinder 6, a support column 8 rotatably connected to the inner wall of the rotating block 7, support plates 9 fixedly connected to both outer walls of the support column 8, the upper surface of the support plate 9 fixedly connected to the lower surface of the support frame 4, and a drive assembly 10 provided on the lower surface of the support frame 4;

[0041] Specifically, the base plate 1 provides fixed support for the fixed plate 2, which in turn supports the connecting column 3, ensuring the stability of the connecting column 3's rotation. This, in turn, supports the support frame 4, allowing it to rotate. Simultaneously, the base plate 1 also provides fixed support for the U-shaped block 5, which in turn supports the hydraulic cylinder 6. The U-shaped block 5 enables the hydraulic cylinder 6 to rotate. When the hydraulic cylinder 6 is activated, it pushes the rotating block 7 to slide. Since the rotating block 7 and the supporting column 8 are rotatably connected, and the U-shaped block 5 and the hydraulic cylinder 6 are also rotatably connected, pushing the rotating block 7 to slide also causes the supporting column 8 to rotate around the connecting column 3, thereby causing the support plate 9 to rotate, and consequently the support frame 4 and the entire device to rotate. By adjusting the device's tilt angle, the disc's tilt angle can be dynamically adjusted according to the material's angle of repose and actual production needs, thus providing more suitable granulation conditions for different materials. This ensures that different material characteristics can slide smoothly and form uniform spheres, improving granule quality.

[0042] Reference Figure 3 The drive assembly 10 includes a motor 1001. The outer wall of the motor 1001 is fixedly connected to the lower surface of the support frame 4. A rotating column 1002 is fixedly provided at the output end of the motor 1001. A gear 1003 is fixedly connected to the outer wall of the rotating column 1002. A gear 1003 is meshed with the tooth end of the gear 1003 and connected to a gear disk 11. A fixed column 12 is rotatably connected to the inner wall of the gear disk 11. The bottom end of the fixed column 12 is fixedly connected to the upper surface of the support frame 4. A disc body 13 is fixedly connected to the upper surface of the gear disk 11.

[0043] Specifically, the support frame 4 can provide fixed support for the motor 1001. When the motor 1001 is turned on, the motor 1001 will drive the rotating column 1002 to rotate, and the rotation of the rotating column 1002 will drive the gear 1003 to rotate. The rotation of the gear 1003 will also drive the gear disk 11 to rotate. The fixed column 12 can provide support for the gear disk 11 to ensure the stable sliding of the gear disk 11. At the same time, when the gear disk 11 rotates, it will also drive the disk body 13 to rotate.

[0044] Reference Figure 3 and Figure 4 A bracket 14 is fixedly connected to the outer wall of the support frame 4, and a fixed frame 15 is fixedly connected to the outer wall of the bracket 14. A spring 16 is fixedly connected to the inner wall of the fixed frame 15, and a sliding plate 17 is provided at the bottom end of the spring 16. The outer wall of the sliding plate 17 is slidably connected to the inner wall of the fixed frame 15. Springs 18 are fixedly connected to both outer walls of the sliding plate 17, and the outer walls of the springs 18 are fixedly connected to the inner wall of the fixed frame 15. A connecting plate 19 is fixedly connected to the lower surface of the sliding plate 17, and a scraper 20 is fixedly connected to the lower surface of the connecting plate 19.

[0045] Specifically, the support frame 4 provides fixed support for the bracket 14, which in turn provides fixed support for the fixed frame 15. The fixed frame 15 also provides fixed support for the spring 16, which in turn provides elastic support for the sliding plate 17. When the sliding plate 17 moves upward, the spring 16 provides cushioning, and the spring 18 also provides elastic support. When the sliding plate 17 moves to the sides, the spring 18 provides cushioning to both sides of the sliding plate 17. The sliding plate 17 provides fixed support for the connecting plate 19, which in turn provides fixed support for the scraper 20. The scraper 20 prevents materials from sticking to the disc wall. Through the elastic connection of the sliding plate 17, the scraper 20 can adapt to changes in the disc surface and the state of the materials, adapting to minor changes in the disc surface, reducing friction with the disc surface, and thus significantly extending the service life of the scraper 20.

[0046] Working principle: When using this device, first activate the hydraulic cylinder 6, which drives the rotating block 7 to slide. The sliding of the rotating block 7 will rotate on the outer wall of the support column 8, thus pushing the support column 8 to slide. At the same time, the sliding of the support column 8 will also drive the support plate 9 to slide, which in turn drives the support frame 4 to slide. Since the connecting column 3 is limited on the inner wall of the fixed plate 2, the sliding of the support frame 4 becomes a rotation around the connecting column 3. By adjusting the sliding distance of the hydraulic cylinder 6, the rotation angle of the support frame 4 can be adjusted, which in turn drives the disc body 13 to rotate. By adjusting the tilt angle of the device, the disc can dynamically adjust the angle according to the characteristics of the material and production needs, thereby providing more suitable granulation conditions for different materials, ensuring that different material characteristics can slide smoothly and form uniform balls, and improving the quality of granule production.

[0047] Then, the motor 1001 is turned on, which drives the rotating column 1002 to rotate, thereby driving the gear 1003 to rotate, which in turn drives the gear disc 11 to rotate, and finally drives the disc body 13 to rotate. The rotation of the disc body 13 allows the inner wall of the scraper 20 to slide. The elastic support of the sliding plate 17 by the spring 16 allows the scraper 20 to be buffered upward. At the same time, the elastic support of the two sides of the sliding plate 17 by the spring 28 allows the scraper 20 to be buffered to the left and right. Through the buffering of the scraper 20, the scraper 20 can be adaptively adjusted according to the changes in the disc surface and the state of the material. It can adapt to the slight changes in the disc surface, reduce the friction between the scraper and the disc surface, and avoid the problem of severe wear caused by the rigid contact between the traditional hard scraper 20 and the disc surface, thereby significantly extending the service life of the scraper 20.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
