Description

Technical Field

[0002] Fertilizer is an indispensable substance in agricultural production and plays an important role in improving crop yield and quality.

[0003] In the fertilizer manufacturing process, converting bulk fertilizer into granules is an important link, namely fertilizer granulation. Fertilizer granulation is not only convenient for storage, transportation and use, but also can improve the utilization rate and effect of fertilizer. In the related art, fertilizer granulation methods include: drum granulation, extrusion granulation, spray granulation, fluidized bed granulation, etc. Among them, the extrusion granulation method refers to mixing fertilizer and binder and squeezing them into granules through an extruder. The extrusion granulation method also has the advantages of high granulation efficiency and low cost, and the size and shape of the particles can be adjusted as needed.

[0004] A Chinese patent with authorization announcement number CN116617941B discloses a granulating device for producing granular fertilizers, which includes: a frame, a conveying sleeve is fixed on the frame, one end of the conveying sleeve is connected to an extrusion barrel, an extrusion sleeve block slidably installed in the extrusion barrel is connected to the reciprocating component, a cutter abutting against the discharge barrel is fixed on the rotating frame, a threaded rod is rotatably installed on the rotating frame, and a translation frame slidably connected to the rotating frame is threadedly sleeved on the threaded rod.

[0005] The above patent realizes automatic discharging of granular fertilizer by enabling the extrusion sleeve to slide reciprocatingly relative to the conveying sleeve and extruding the fertilizer raw materials inside the extrusion cylinder. The raw materials are cut by the cutter during discharge through the extrusion hole, thereby realizing the automatic discharging effect of granular fertilizer. The threaded rod drives the translation frame to move reciprocatingly linearly, so that the scraper can scrape the granular fertilizer attached to the cutter, effectively reducing the probability of adhesion of the granular fertilizer and greatly improving the granulation effect of the granular fertilizer.

[0006] However, since the reciprocating extrusion mechanism in the above patent has a limited and fixed length and the material in the extrusion barrel is difficult to quantify, the particle size of the extruded material is uneven when the material is more or less. Summary of the invention

[0039] like Figure 2 , Figure 5 and Figure 6As shown, a driving mechanism is provided on the rotating shaft 3, and the driving mechanism includes a driving shaft 91, a third driving member 92, a first gear 93, a second gear 94 and a hinge rod 96. The driving shaft 91 is arranged in the rotating shaft 3 and is rotatably matched with the rotating shaft 3. The third driving member 92 is arranged in the rotating shaft 3. The third driving member 92 is a motor, and its output end is fixedly connected to the driving shaft 91. The third driving member 92 is used to drive the driving shaft 91 to rotate. The first gear 93 is fixedly connected to the circumference of the driving shaft 91. A connecting rod 95 is provided on the second gear 94. The second gear 94 is located in the rotating shaft 3. The connecting rod 95 passes through the side wall of the rotating shaft 3 and extends outward. The connecting rod 95 is rotatably matched with the rotating shaft 3. The first gear 93 is meshed with the second gear 94. One end of the hinge rod 96 is rotatably connected to the connecting rod 95, and the other end thereof is hinged to the sliding rod 861. The first gear 93 rotates synchronously with the driving shaft 91 and drives the second gear 94 to rotate. The connecting rod 95 rotates synchronously with the second gear 94 and drives the hinged rod 96 to rotate around the axis of the connecting rod 95, so that the hinged rod 96 drives the sliding rod 861 to reciprocate along the axis direction of the second connecting rod 86.

[0040] like Figure 3 As shown, a scraper block 10 is provided at the bottom end of the second quantitative plate 84, the top end of the scraper block 10 is rotatably connected to the second quantitative plate 84, the bottom end of the scraper block 10 is abutted against the forming plate 6, and the side of the scraper block 10 close to the squeezing roller 7 is an inclined surface structure. A flip rod 11 is also provided at the bottom end of the second quantitative plate 84, and a plurality of flip rods 11 are evenly spaced and distributed on the second quantitative plate 84 in the horizontal direction. An opening is also provided on the second quantitative plate 84, the opening is close to the bottom end of the second positioning plate, and the opening is located above the flip rod 11.

[0041] like Figure 1 As shown, a discharge port is provided at the bottom of the extrusion cylinder 2, the bottom end of the discharge port is flush with the bottom surface of the extrusion cylinder 2, and a discharge hopper 13 is also provided at the discharge port. A lever 14 is fixedly connected to the rotating shaft 3, the outer end of the lever 14 abuts against the inner wall of the extrusion cylinder 2, and the bottom end of the lever 14 abuts against the bottom surface of the extrusion cylinder 2.

[0042] According to the high-efficiency fertilizer granule manufacturing machine of the present invention, the material is poured into the extrusion cylinder 2 from the feed port, and the material is distributed on the forming plate 6. At this time, there is a gap between the bottom end of the first quantitative plate 83 and the forming plate 6. The first driving member 4 drives the rotating shaft 3 to rotate clockwise through the transmission belt 5, thereby driving the extrusion roller 7 to roll clockwise on the forming plate 6. Before the extrusion roller 7 extrude the material, the first quantitative plate 83 will scrape the material flat, so that the thickness of the material is kept consistent when the extrusion roller 7 extrude the material. While the rotating shaft 3 rotates, the driving mechanism drives the sliding rod 861 to reciprocate on the second connecting rod 86, thereby driving the second The bottom end of the quantitative plate 84 moves back and forth, thereby causing the angle between the first quantitative plate 83 and the second quantitative plate 84 to periodically increase and decrease. During this process, excess material moves along the first quantitative plate 83 from the bottom end of the first quantitative plate 83 to its top end. During the movement, the stirring rod 12 can stir and turn the material on the first quantitative plate 83, and the material moves from the top end of the first quantitative plate 83 to the second quantitative plate 84, and moves along the second quantitative plate 84 from the top end of the second quantitative plate 84 to the bottom end of the second quantitative plate 84, and finally detaches from the second quantitative plate 84 and returns to the forming plate 6. The squeezing roller 7 squeezes the material after being scraped flat by the first quantitative plate 83, and squeezes the material into the forming hole of the forming plate 6, so as to squeeze the material into particles. After the extrusion is completed, the scraper block 10 can scrape the place where the squeezing roller 7 has squeezed to prevent the material from adhering to the forming plate 6. The material scraped off by the scraper block 10 will be concentrated on the inclined structure of the scraper block 10. The bottom end of the second quantitative plate 84 will drive the flip rod 11 to swing back and forth during the reciprocating movement. The flip rod 11 can flip and stir the material concentrated on the inclined structure of the scraper block 10, so that the squeezed material is restored to a loose state. The flipped material is discharged from the opening of the second quantitative plate 84 and redistributed on the forming plate 6.

[0043] When there is less material in the extrusion cylinder 2, the second driving member 82 drives the movable shaft 81 to move downward, and the movable shaft 81 makes the first quantitative plate 83 stop against the forming plate 6 through the first connecting rod 85. When the rotating shaft 3 rotates, the material will be shoveled from the forming plate 6 to the top of the first quantitative plate 83 to prevent the material from contacting the extrusion roller 7, thereby preventing the extrusion roller 7 from extruding a small amount of material, and further preventing the extrusion of a small amount of material from causing uneven material particle size.

[0044] The formed granular material falls to the bottom of the extrusion cylinder 2, and the rotation of the rotating shaft 3 also drives the lever 14 to rotate, and the lever 14 can move the material at the bottom of the extrusion cylinder 2 to the discharge port.
