[0020] Figure 1 to Figure 5 It is the best embodiment of the utility model, and the following Figure 1 ~Attached Figure 5 The utility model is further described.

[0021] See attached Figure 1-Figure 5 The utility model discloses a trace element water-soluble fertilizer granulator, including a workbench 1, the workbench 1 is hollow, a protective cylinder 2 is fixedly installed on the top of the workbench 1, a feeding assembly 3 is arranged in the protective cylinder 2, a screen cylinder 4 is arranged on the top of the feeding assembly 3, a stirring and extruding assembly 5 is arranged in the screen cylinder 4, a cleaning assembly 6 for cleaning the inner surface of the screen cylinder 4 is arranged on the stirring and extruding assembly 5, a feeding pipe 7 is fixedly installed on the top of the screen cylinder 4, a plurality of connecting strips 8 are fixedly installed on the surface of the feeding pipe 7, and the plurality of connecting strips 8 are fixedly connected to the protective cylinder 2, and a driving assembly 9 for driving the feeding assembly 3, the stirring and extruding assembly 5 and the cleaning assembly 6 to rotate is arranged in the workbench 1.

[0022] In this embodiment, when in use, the staff puts the pretreated fertilizer into the feed pipe 7, and the fertilizer falls on the stirring and extruding component 5 through the feed pipe 7 and is located in the screen cylinder 4. At this time, the driving component 9 drives the unloading component 3, the stirring and extruding component 5 and the cleaning component 6 to rotate, and the fertilizer is stirred and extruded by the stirring and extruding component 5, so that the fertilizer is squeezed out through the mesh holes on the screen cylinder 4, thereby forming into particles, and falls on the unloading component 3, and is unloaded through the unloading component 3. The screen cylinder 4 is made of rigid material and will not be deformed due to extrusion.

[0023] Specifically, the driving assembly 9 includes a motor 901, a power rod 902 and a support bar 903. The motor 901 is arranged in the workbench 1. One end of the support bar 903 is fixedly connected to the inner wall of the workbench 1. The motor 901 is installed on the support bar 903. One end of the power rod 902 is fixedly connected to the output end of the motor 901, and the other end can be rotatably passed through the workbench 1 and extended into the screen drum 4.

[0024] In this embodiment, when in use, the motor 901 is started, and the motor 901 drives the power rod 902 to rotate, and the support bar 903 mainly plays the role of fixing the motor 901.

[0025] Specifically, the material discharge assembly 3 includes a circular block 301, a disc 302, a baffle 303 and a material discharge pipe 304. The circular block 301 is fixedly mounted on the power rod 902. The bottom of the circular block 301 is rotatably connected to the top of the workbench 1 and is located in the protective cylinder 2. The disc 302 is fixedly mounted on the circular block 301. The disc 302 fits the inner wall of the protective cylinder 2 and can slide relatively. The material discharge pipe 304 is arranged on one side of the protective cylinder 2 and is connected to the protective cylinder 2. The baffle 303 is fixedly mounted on the disc 302 and slidably cooperates with the inner wall of the protective cylinder 2. The screen cylinder 4 is rotatably connected to the top of the circular block 301.

[0026] In this embodiment, when the power rod 902 rotates, the power rod 902 drives the circular block 301 to rotate, and the circular block 301 drives the disc 302 and the baffle 303 to rotate. When the granular fertilizer squeezed out by the screen cylinder 4 falls on the disc 302, the rotating baffle 303 drives the granular fertilizer to rotate, and the centrifugal force generated by the rotation causes the granular fertilizer to gather toward the inner wall of the protective tube 2 and be blocked by the inner wall of the protective tube 2. When it rotates to the discharge pipe 304, because there is no obstruction from the inner wall of the protective tube 2, the granular fertilizer enters the discharge pipe 304 for discharge.

[0027] Furthermore, the baffle 303 is fixedly mounted on the inner wall of the protective tube 2 and is located on one side of the feed pipe 304 . The baffle 303 and the disc 302 can rotate relative to each other. When the disc 302 drives the granular fertilizer to move to the baffle 303 , the baffle 303 will block the fertilizer and allow the fertilizer to enter the feed pipe 304 .

[0028] Specifically, the stirring and extruding assembly 5 includes a fixed plate 501, a plurality of stirring blades 502 and a plurality of arc-shaped extrusion plates 503. The fixed plate 501 is sleeved on the power rod 902 and is rotatably connected to the power rod 902. The fixed plate 501 is fixedly connected to the inner surface of the screen drum 4. The plurality of stirring blades 502 are fixedly installed on the power rod 902 in a circular shape and at equal intervals. The plurality of arc-shaped extrusion plates 503 are fixedly installed on the power rod 902 in a circular shape and at equal intervals. The ends of the plurality of arc-shaped extrusion plates 503 close to the screen drum 4 are arc-shaped. The arc-shaped portions of the plurality of arc-shaped extrusion plates 503 are in contact with the inner surface of the screen drum 4. The plurality of arc-shaped extrusion plates 503 are located below the plurality of stirring blades 502. The bottom of the plurality of arc-shaped extrusion plates 503 slides with the top of the fixed plate 501.

[0029] In this embodiment, when the fertilizer enters the area of ​​the screen drum 4 and falls on the fixed plate 501, it is rotated by the power rod 902 at the same time. At this time, the plurality of stirring blades 502 and the plurality of arc-shaped extrusion plates 503 rotate, so that the stirring blades 502 stir the fertilizer to prevent accumulation, and the stirred fertilizer is driven to rotate by the plurality of arc-shaped extrusion plates 503. Because of the centrifugal force generated by the rotation, the fertilizer moves toward the screen drum 4 at this time, so that the fertilizer moves along the vertical part of the arc-shaped extrusion plate 503 toward the arc-shaped part of the arc-shaped extrusion plate 503. When the fertilizer contacts the arc-shaped part of the arc-shaped extrusion plate 503, the fertilizer is located between the arc-shaped part of the arc-shaped extrusion plate 503 and the screen drum 4, and the fertilizer is squeezed by the arc-shaped part of the arc-shaped extrusion plate 503 and rotates along the screen drum 4, so that the squeezed fertilizer becomes granular after passing through the holes of the screen drum 4 and falls into the unloading component 3.

[0030] Specifically, the cleaning assembly 6 includes a plurality of fixed rods 601 and a plurality of scrapers 602 . The plurality of fixed rods 601 are fixedly connected to the power rod 902 in a circular shape and equidistantly. The plurality of scrapers 602 are fixedly connected to the corresponding fixed rods 601 , respectively. The plurality of scrapers 602 are all in contact with the inner surface of the screen drum 4 .

[0031] In this embodiment, when the power rod 902 rotates, the power rod 902 drives the fixed rods 601 to rotate, and the fixed rods 601 drive the scraper 602 to rotate. The scraper 602 rotates along the screen cylinder 4, and the fertilizer is squeezed by the arc extrusion plate 503, so that the fertilizer remains in the area between the holes of the screen cylinder 4. The fertilizer remaining on the inner surface of the screen cylinder 4 is scraped off by the rotating scraper 602, and reprocessed with the remaining fertilizer to prevent the fertilizer from remaining in the area between the holes of the screen cylinder 4, thereby preventing fertilizer waste.

[0032] Specifically, a plurality of universal wheels 10 with a self-locking function are arranged at the bottom of the workbench 1 .

[0033] In this embodiment, the universal wheels 10 are used to improve the flexibility of the device, making it more convenient to move.
