Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] However, in actual use, when the collector is used for a long time, organic fertilizer can easily clog the discharge port, making it inconvenient to squeeze the material. When the blockage occurs, the extrusion plate needs to be disassembled and the discharge port on the surface of the extrusion plate needs to be cleared, which makes it inconvenient for workers to use.

[0021] In view of this, the present invention provides an anti-clogging structure for the outlet of an extruder, which solves the problem that in actual use, when the extruder is used for a long time, organic fertilizer can easily clog the outlet, making it inconvenient to extrude. When the blockage occurs, the extrusion plate needs to be disassembled and the outlet on the surface of the extrusion plate needs to be cleared, which is inconvenient for workers.

The anti-clogging structure includes a mounting shell 10, a second servo motor 12, a drive rod 17, a cam 18, a mounting plate 14, and an extrusion block 15. The outer wall of the mounting shell 10 is fixedly connected to the top of the extrusion plate 9 by bolts. The top of the mounting shell 10 is fixedly connected to the second servo motor 12. The output end of the second servo motor 12 extends into the interior of the mounting shell 10 and is fixedly connected to the drive rod 17. The outer wall of the drive rod 17 is fixedly connected to the cam 18. The outer wall of the cam 18 abuts against the mounting plate 14. The outer wall of the mounting plate 14 is movably connected to the inner wall of the mounting shell 10. The outer wall of the mounting plate 14 is fixedly connected to the extrusion block 15. The model of the second servo motor 12 is not limited, as long as it meets the actual use requirements.

[0024] In the specific implementation process, it is worth noting that, with the cooperation of the second servo motor 12, cam 18 and extrusion block 15, the second servo motor 12 drives the drive rod 17 to rotate, and the cam 18 extrudes the mounting plate 14, and drives the extrusion block 15 to extrude the discharge port on the extrusion plate 9, opening the discharge port on the surface of the extrusion plate 9, avoiding blockage of the discharge port, which would cause inconvenience to workers when handling it;

[0025] Furthermore, a first servo motor 7 is fixedly connected to the outer wall of the extrusion shell 6. A screw rod 8 is fixedly connected to one end of the output end of the first servo motor 7 that extends into the interior of the extrusion shell 6. The outer wall of the screw rod 8 is rotatably connected to the inner wall of the extrusion plate 9 through a bearing. A cutter 13 is fixedly connected to one end of the screw rod 8 that extends into the outer wall of the extrusion plate 9. The model of the first servo motor 7 is not limited, as long as it meets the actual usage requirements.

[0026] In the specific implementation process, it is worth noting that, with the cooperation of the first servo motor 7, the extrusion plate 9 and the cutter 13, the first servo motor 7 drives the screw rod 8 to rotate, extruding the fertilizer and extruding it through the opening on the upper layer of the extrusion plate 9, which will drive the cutter 13 to rotate and cut the extruded fertilizer into particles of the same size.

[0027] Furthermore, the inner wall of the mounting shell 10 is rotatably connected to a connecting rod 16 via a bearing, the outer wall of the connecting rod 16 is movably connected to the inner wall of the mounting plate 14, one end of the connecting rod 16 is fixedly connected to an insert block 19, the outer wall of the insert block 19 is inserted into one end of the spiral rod 8, and the inner wall of the mounting shell 10 is fixedly connected to a tension spring 11, one end of the tension spring 11 is fixedly connected to the outer wall of the mounting plate 14.

[0028] In the specific implementation process, it is worth noting that, with the cooperation of the connecting rod 16, the insert block 19 and the mounting plate 14, the connecting rod 16 inside the mounting shell 10 is inserted into the outer wall of the spiral rod 8 and fixed by bolts, so that the mounting plate 14 is stable when moving.

[0029] Specifically, when using the anti-clogging structure at the outlet of the extruder, fertilizer enters the housing 1 through the feed inlet 2, and the first servo motor 7 drives the screw rod 8 to rotate, causing the fertilizer to be discharged through the through hole on the outer wall of the extrusion plate 9, and driving the cutter 13 to rotate, cutting the fertilizer into granules. When the extrusion plate 9 becomes clogged, the first servo motor 7 is turned off, and the second servo motor 12 drives the cam 18 to rotate, pressing the mounting plate 14, causing the mounting plate 14 to move on the outer wall of the connecting rod 16, so that the extrusion block 15 presses the through hole on the extrusion plate 9 to clear it and prevent clogging, making it convenient for workers to use.

[0030] Example 2: From Figure 1-4 It can be seen that the inner wall of the box 1 is provided with a stirring rod 5, the outer wall of the stirring rod 5 is rotatably connected to the inner wall of the box cover 4 through a bearing, and the end of the stirring rod 5 extending to the top of the box cover 4 is fixedly connected to a stirring motor 3. The outer wall of the stirring motor 3 is fixedly connected to the top of the box cover 4. The model of the stirring motor 3 is not limited, as long as it meets the actual use.

[0031] In the specific implementation process, it is worth noting that, with the cooperation of the mixing motor 3, the box cover 4 and the mixing rod 5, the fertilizer is added into the box 1 through the feed port 2, and the mixing motor 3 drives the mixing rod 5 to rotate, so that the fertilizer is fully mixed. After the fertilizer is mixed, it will enter the extrusion shell 6, and under the action of the screw rod 8, the fertilizer is extruded and discharged, which increases the extrusion speed of the fertilizer.

[0032] Furthermore, a slider 20 is fixedly connected to the outer wall of the extrusion plate 9, and the outer wall of the slider 20 is slidably engaged with the inner wall of the extrusion shell 6.

[0033] In the specific implementation process, it is worth noting that, with the cooperation of the slider 20 and the extrusion shell 6, when installing the extrusion plate 9, the slider 20 is inserted into the inside of the extrusion shell 6 and fixed with bolts to make it more stable.

[0034] Specifically, based on the above embodiments, when extruding fertilizer, the stirring motor 3 drives the stirring rod 5 to rotate, so that the fertilizer is fully mixed and enters the extrusion shell 6 for extrusion. It is discharged through the opening on the surface of the extrusion plate 9. When blockage occurs, the first servo motor 7 stops rotating, while the second servo motor 12 drives the cam 18 to rotate, which drives the extrusion block 15 to clear the blockage of the extrusion plate 9, making it convenient for the staff to use.
