Description

Technical Field

[0001] The invention relates to the technical field of granulators, in particular to an organic fertilizer granulator with adjustable radius. Background Art

[0002] Organic fertilizer granulator is a kind of mechanical equipment used to make fertilizer raw materials (such as organic matter, inorganic salts, etc.) into uniform particles through mixing and granulation processes. It is widely used in agriculture, horticulture and other fields.

[0003] In the fertilizer granulation production process, ensuring the uniformity of feeding is the key link in determining product quality. Unstable feeding, whether due to the performance limitations of the feeder or the inconsistency of manual feeding, will directly cause fluctuations in the extrusion pressure output by the granulator. In addition, moisture, impurities or uneven distribution in the raw materials may cause changes in resistance during the extrusion process, which will also affect the stability of the extrusion force. Fluctuations in extrusion pressure caused by any reason will eventually affect the quality of the finished fertilizer granules: on the one hand, it may cause the granules to be larger than expected, and on the other hand, there may be missing or too small granules, which do not meet the standard requirements of the market or agricultural applications.

DETAILED DESCRIPTION

[0030] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0031] Embodiment 1: A radius-adjustable organic fertilizer granulation device, such as Figures 1 to 4As shown, it includes a base 1, an extruder 2 is fixedly connected to the left side of the base 1, and a round rod 4 symmetrically distributed along the front and back of the extruder 2 is fixedly connected to the side of the extruder 2 near the outlet through a nut 5, and a pellet extrusion disk 3 is slidably sleeved between the round rods 4 symmetrically distributed along the left and right directions. The pellet extrusion disk 3 has a plurality of pellet extrusion holes in an annular array for extruding fertilizer into shape, and the pellet extrusion disk 3 slides along the left and right directions on the right side of the extruder 2. A first spring 6 is sleeved on the round rod 4, and the left and right ends of the first spring 6 are in contact with the pellet extrusion disk 3 and the adjacent nut 5 respectively. A motor 7 is fixedly connected to the right side, and a rotating rod 8 is fixedly connected to the output shaft of the motor 7. A cutting frame 9 is splined to the rotating rod 8. The cutting frame 9 can slide horizontally in the left and right directions in the rotating rod 8. Four annularly distributed cutters are arranged at the left end of the cutting frame 9. The cutters move to the left and contact the end surface of the pelletizing disk 3. The cutters are used to pelletize the fertilizer extruded by the pelletizing disk 3. A filtering inclined plate 10 is fixedly connected to the right side of the upper part of the base 1. The filtering inclined plate 10 has evenly distributed filter holes for screening out small-size fertilizer particles. The filtering inclined plate 10 is inclined to the lower right. , used for feeding fertilizer particles with moderate particle size, the front and rear sides of the left part of the filter inclined plate 10 are not in contact with the base 1, and used for feeding fertilizer particles with large particle size, the front and rear sides of the right part of the filter inclined plate 10 are in contact with the base 1 to prevent the moderate particle size fertilizer particles from falling from the front and rear sides of the project, and the base 1 is close to the side 1 of the filter inclined plate 10. The blocking plate 11 is used to block the fertilizer particles with large particle size from passing to the right, and the bottom of the blocking plate 11 is in contact with the filter inclined plate 10, and the rotating rod 8 is connected with a slide plate 12 in a sliding manner along the left and right directions, and the left side of the slide plate 12 A second spring 13 is fixedly connected to the end, and the left end of the second spring 13 is in contact with the cutting frame 9. A spiral steel spring 14 is wound around the right part of the rotating rod 8. A protrusion 15 is fixedly connected to the rotating rod 8. The protrusion 15 is limited by the spiral steel spring 14. When the protrusion 15 rotates, it drives the steel spring 14 to move to the left. A slide groove 16 symmetrically distributed along the front and back of the slide plate 12 is opened on the upper right part of the base 1. The slide groove 16 is used to limit the slide plate 12. A collecting groove 23 is opened on the side of the base 1 close to the extruder 2 for collecting large-size fertilizer particles and small-size fertilizer particles.

[0032] Initially, a certain space is reserved between the cutting frame 9 and the pelletizing disk 3 to facilitate safe cleaning of the pelletizing disk 3 and prevent the cutting knife of the cutting frame 9 from accidentally injuring the operator. When the granulating device is needed to granulate organic fertilizer, first select a pelletizing disk 3 with a suitable aperture according to the radius of the fertilizer to be extruded, slide the pelletizing disk 3 onto the round rod 4, put the first spring 6 on the round rod 4, and then screw the nuts 5 on the left and right ends of the round rod 4. In this way, the radius of the pelletizing hole can be quickly adjusted.

[0033] After the above preparations are completed, the raw materials of organic fertilizer are poured into the extruder 2 through the feed port, and then the output shaft of the motor 7 is controlled to drive the rotating rod 8 to rotate. The rotating rod 8 drives the steel spring 14 to move to the left through the protrusion 15, thereby driving the slide plate 12 to slide to the left along the slide groove 16. The slide plate 12 drives the cutter of the cutting frame 9 to move to the left synchronously through the second spring 13 until it contacts the right end surface of the particle extrusion plate 3. At this time, it is ensured that the first spring 6 and the second spring 13 are both in a natural state, and the extruder 2 is turned on. The extruder 2 outputs a suitable extrusion force, and the particle extrusion plate 3 is affected by the output extrusion force and moves along the round rod 4. Sliding to the right, the first spring 6 is compressed, the cutting frame 9 adaptively slides to the right along the rotating rod 8, the second spring 13 is compressed, the fertilizer is extruded through the extruding hole of the extruding disk 3, and the cutter of the cutting frame 9 cuts the extruded fertilizer into fertilizer particles, thus realizing the fertilizer granulation operation. After the granulation is completed, the extruder 2 is controlled to be closed, and the output shaft of the motor 7 is controlled to drive the rotating rod 8 to reverse, and the rotating rod 8 drives the steel spring 14 to move to the right through the protrusion 15, thereby driving the slide plate 12 to slide to the right along the slide groove 16, and the slide plate 12 drives the cutter of the cutting frame 9 to move to the right synchronously through the second spring 13 to reset.

[0034] During the above-mentioned extrusion granulation process, the particle extrusion disk 3 will automatically adapt to the fluctuation of the output size of the extrusion force. If the output extrusion force becomes larger, the particle extrusion disk 3 continues to slide to the right along the round rod 4, the first spring 6 is further compressed, the cutting rack 9 also adaptively continues to slide to the right along the rotating rod 8, and the second spring 13 is further compressed. If the output extrusion force becomes smaller, the first spring 6 reduces the degree of compression, so that the particle extrusion disk 3 slides to the left along the round rod 4, and the second spring 13 also adaptively reduces the degree of compression, so that the cutting rack 9 slides to the left along the rotating rod 8. In this way, the particle extrusion disk 3 adaptively slides left and right to adaptively offset the output fluctuation of the extrusion force, thereby reducing the negative impact of the output fluctuation of the extrusion force on the granulation of organic fertilizers.

[0035] In the above-mentioned extrusion granulation process, a collecting bag is put on the lower right side of the filter inclined plate 10, and the fertilizer particles cut by the cutting frame 9 fall on the filter inclined plate 10. The fertilizer with larger particle size is blocked by the blocking plate 11 on the left side of the filter inclined plate 10, and is discharged into the collecting groove 23 of the base 1 along the front and rear sides. The fertilizer with medium and smaller particle size rolls to the right to the right side of the filter inclined plate 10 through the blocking plate 11, and the fertilizer with smaller particle size is also discharged downward into the collecting groove 23 of the base 1 through the filter holes on the right side of the filter inclined plate 10. The fertilizer with moderate particle size rolls to the lower right along the filter inclined plate 10 into the collecting bag, so as to achieve the screening and collection of unqualified fertilizer particles and qualified fertilizer particles with moderate particle size.

[0036] Embodiment 2: Based on embodiment 1, Figure 5As shown, it also includes a shaking frame 17 for shaking off large-size fertilizer particles. The shaking frame 17 is slidably connected to the base 1, and the right side of the shaking frame 17 is in contact with the material blocking plate 11. The left end of the rotating rod 8 is provided with annularly distributed protrusions, and the protrusions of the rotating rod 8 intermittently contact the middle top of the shaking frame 17. The shaking frame 17 is inclined to the right, and the middle of the shaking frame 17 is high and the front and rear sides are low, which is used to accelerate the discharge of large-size fertilizer particles and prevent accumulation. A third spring 18 symmetrically distributed along the front and back of the shaking frame 17 is fixedly connected between the shaking frame 17 and the base 1.

[0037] In order to prevent excessive accumulation of materials in the middle position on the left side of the filtering inclined plate 10, the scraped materials are diffused and diverted by the four cutting knives of the cutting frame 9, and the materials are uniformly tilted to the lower right to the material blocking plate 11. Moderate and too small particles all pass through the material blocking plate 11, and oversized particles remain on the shaking frame 17. The shaking frame 17 is intermittently squeezed by the protrusion on the rotating rod 8 to slide downward. At the same time, under the action of the third spring 18, the shaking frame 17 intermittently slides upward, so as to realize the intermittent up and down shaking of the shaking frame 17, thereby assisting the unqualified oversized particles to tilt and slide to the front and rear sides, so as to avoid material accumulation during the separation process.

[0038] Embodiment 3: Based on embodiment 2, Figure 6 As shown, it also includes a pressure frame 19, which is slidably connected to the right side of the extruder 2 along the up and down directions, and is engaged with the pelletizing disk 3. A tension spring 20 is fixedly connected between the pressure frame 19 and the extruder 2, and a retaining ring 21 is fixedly connected to the side of the extruder 2 close to the pelletizing disk 3, and the retaining ring 21 is used to block the pelletizing hole of the pelletizing disk 3.

[0039] In order to prevent the extruder 2 from extruding materials before the material is fully piled near the pelletizing plate 3 during pelletizing, which results in loose pelletizing and honeycomb-shaped finished products, the following operations are performed to ensure that the material at the pelletizing plate 3 is fully piled before extruding:

[0040] Initially, the retaining ring 21 blocks the pellet extrusion hole on the pellet extrusion disk 3. Only when the material at the pellet extrusion disk 3 is full, the pressure of the material is sufficient to extrude the pressure frame 19 upward, and the tension spring 20 is stretched. At this time, the pressure frame 19 releases the lock on the pellet extrusion disk 3, and the pellet extrusion disk 3 slides to the right under the pressure of the material. The pellet extrusion disk 3 is no longer in contact with the retaining ring 21. The material passes to the right through the gap of the retaining ring 21 and is extruded and granulated through the pellet extrusion hole of the pellet extrusion disk 3.

[0041] When the amount of material at the pellet extrusion disk 3 becomes less again, the tension spring 20 resets and drives the pressure frame 19 to slide downward and reset. The pellet extrusion disk 3 is reset to contact with the pressure frame 19 under the action of the first spring 6, and squeezes the pressure frame 19 to slide upward, so that the tension spring 20 is stretched again. Until the pressure frame 19 clamps the pellet extrusion disk 3 again, the tension spring 20 resets. At this time, the retaining ring 21 blocks the pellet extrusion hole of the pellet extrusion disk 3 again to prevent the extrusion of material.

[0042] Embodiment 4: Based on embodiment 3, Figure 7 and Figure 8 As shown, a baffle 22 is also included, which is slidably connected to the material blocking plate 11. A movable groove is opened on the front side of the material blocking plate 11. The baffle 22 is used to block the movable groove, and the rotating rod 8 is pressed and matched with the baffle 22.

[0043] In order to facilitate the backward pulling of the material blocking plate 11 for cleaning, the material blocking plate 11 is affected by the rotating rod 8, and a movable groove is opened on the front side thereof. In order to prevent unqualified products on the left side from splashing to the right side through the movable groove, a baffle 22 is provided to block the movable groove. In the process of pulling out the material blocking plate 11, the baffle 22 moves backward with the material blocking plate 11, and is squeezed by the rotating rod 8. The baffle 22 automatically slides upward over the rotating rod 8, and then automatically slides downward and resets under the action of gravity.

[0044] The above embodiments are provided for persons familiar with the art to implement or use the present invention. Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
