[0028] In this embodiment, Figure 1-8 A novel granulator for compound fertilizer production is provided. The utility model comprises a vertical box 1. A cylinder 2 is vertically arranged inside the vertical box 1. Both ends of the cylinder 2 are fixedly connected to the inner wall of the vertical box 1 with a connecting frame 3. The curved surface of the cylinder 2 is provided with a through hole 1 41, a through hole 2 42 and a through hole 3 43 with gradually decreasing apertures from top to bottom. An extrusion mechanism is arranged inside the cylinder 2. Two slide cylinders 6 are slidingly sleeved on the cylinder 2 and correspond to the through hole 1 41 and the through hole 3 43 respectively. A particle scraping mechanism is arranged between the two slide cylinders 6. An adjustment mechanism is provided on the vertical box 1 for adjusting the vertical positions of the slide cylinder 6 and the extrusion mechanism.
[0029] It should be noted that the number of through holes 1 41, through holes 2 42 and through holes 3 43 is multiple, which can increase the amount of extruded raw materials, and the vertical positions of the two slides 6 and the extrusion mechanism can be changed by the adjustment mechanism. The two slides 6 move vertically to block two of the through holes 1 41, through holes 2 42 and through holes 3 43, and the other one leaks out and is located between the two slides 6 to serve as a hole for extruding the raw materials. At this time, the raw materials of the cylinder 2 can be squeezed out of the leaked through holes by the extrusion mechanism, and the extruded raw materials can be scraped and cut into particles by the scraping mechanism for granulation. Since the apertures of through holes 1 41, through holes 2 42 and through holes 3 43 gradually increase, one of the through holes 1 41, through holes 2 42 and through holes 3 43 leaks out through adjustment and serves as an extrusion hole to produce fertilizer particles of different sizes, thereby improving the applicability of the equipment.

The top of the upper disc 54 is provided with a motor 51 whose output shaft is coaxially connected to the upper end of the connecting rod 53.
[0031] In this embodiment, when the connecting rod 53 rotates, it will drive the connected spiral blade 52 to rotate synchronously and generate a downward propulsion force, and the raw material inside the cylinder 2 is pushed downward, and finally, it presses against the bottom disc 54 and is then squeezed out of the through hole 2 42, and the motor 1 51 is used as a driving device to drive the connecting rod 53 to rotate.
[0032] Preferably, as another embodiment of the utility model, the scraping mechanism includes a circular ring 81, a second motor 82, a gear ring 83, a transmission shaft 84, a gear 85, a scraper 86 and an annular groove 87.

Gear rings 83 are fixedly sleeved on the two circular rings 81. A scraper 86 is fixedly connected between the two circular rings 81. The outer side of the upper slide 6 is fixedly connected with the second motor 82. The output shaft of the second motor 82 is coaxially connected with a transmission shaft 84, the other end of which is rotatably connected to the lower slide 6. Two gears 85 are fixedly sleeved on the transmission shaft 84 and are respectively meshed with the two gear rings 83.
[0033] In this embodiment, when the raw material is extruded out of the through hole 42, the transmission shaft 84 is driven to rotate by the motor 82, and the gear 85 installed on the transmission shaft 84 rotates accordingly and meshes with the gear ring 83 on the ring 81, so that the ring 81 rotates inside the annular groove 87. During this process, the ring 81 drives the scraper 86 to rotate. There are multiple scrapers 86, and the rotating scraper 86 will scrape and cut the extruded cylindrical raw material into granules for granulation.
[0034] Preferably, as another embodiment of the utility model, the adjusting mechanism includes a lifting plate 71, a cylinder 72, a connecting rod 1 73, a connecting rod 2 74 and a fixed block 75. A lifting plate 71 is provided above the vertical box 1. The bottom of the lifting plate 71 is provided with a connecting rod 1 73 whose lower end extends to the interior of the cylinder 2 and is fixedly connected to the top of the upper disc 54. Both sides of the slide cylinder 6 are fixedly connected with fixed blocks 75. Both sides of the bottom of the lifting plate 71 are fixedly connected with connecting rod 2 74 extending to the interior of the vertical box 1 and passing through the fixed block 75 on the same side. The connecting rod 2 74 is fixedly connected to the penetration point on the fixed block 75. Both sides of the vertical box 1 are provided with a cylinder 72 with a telescopic shaft fixedly connected to the bottom of the lifting plate 71.
[0035] In this embodiment, the telescopic end of the starter cylinder 72 extends or retracts, and the lifting plate 71 connected to the telescopic end moves, and through the connection between the connecting rod 1 73, the connecting rod 2 74 and the fixed block 75, the lower disc 54 and the two slide cylinders 6 are driven to move up or down, so that one of the through hole 1 41, the through hole 2 42 and the through hole 3 43 leaks out, and the other two are covered by the two slide cylinders 6, so as to replace one of the through hole 1 41, the through hole 2 42 and the through hole 3 43 as the extrusion hole, so as to realize the production of particles of different sizes.
[0036] Preferably, as another embodiment of the utility model, the curved surface of the cylinder 2 is provided with a feed hopper 91 extending to the outside of the vertical box 1, and the raw materials can be poured into the interior of the cylinder 2 through the feed hopper 91. The lower end of the outside of the vertical box 1 is provided with a discharge hopper 92, and the discharge hopper 92 can be used to discharge fertilizer particles. The inner wall of the vertical box 1 is provided with a guide plate 93, and the guide plate 93 is inclined toward the side opposite to the discharge hopper 92, so that the particles falling on the surface of the guide plate 93 flow along the surface of the guide plate 93 to the discharge hopper 92, so as to guide the discharge of the fertilizer particles.
[0037] Working principle: As the apertures of through hole 1 41, through hole 2 42 and through hole 3 43 gradually increase, one of them is selected as the extrusion hole according to the demand to control the size of the extruded raw material. The process is to start the telescopic end of the cylinder 72 to extend or retract, and the lifting plate 71 connected to the telescopic end moves, and through the connection of the connecting rod 1 73, the connecting rod 2 74 and the fixed block 75, the lower disc 54 and the two slide cylinders 6 are driven to move up or down, so that one of the through hole 1 41, through hole 2 42 and through hole 3 43 leaks out, and the other two are covered by the two slide cylinders 6, so as to replace one of the through hole 1 41, through hole 2 42 and through hole 3 43. As an extrusion hole, then, the raw material is poured into the cylinder 2 through the feed hopper 91, and at the same time, the motor 1 51 is started to drive the connecting rod 53 and the spiral blade 52 to rotate, which can generate a propulsion force to transport the raw material downward, and cooperate with the disc 54 to extrude the raw material leaking out of the through hole to form a cylindrical raw material. At this time, the motor 2 82 drives the transmission shaft 84 and the gear 85 to rotate, and the gear 85 will engage with the gear ring 83 on the ring 81 to drive the ring 81 and the scraper 86 to rotate, and the rotating scraper 86 will scrape and cut the extruded cylindrical raw material into particles for granulation, and fall downward, and finally, it is discharged from the discharge hopper 92 along the guide plate 93.
