Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer particle production, in particular to a large-particle composite fertilizer granulation device. Background Art

[0002] In agricultural production, fertilizers need to be added according to demand. Fertilizers contain mineral elements such as nitrogen, phosphorus, and potassium. Therefore, fertilizers are a key factor in improving soil fertility and helping the growth of current crops. Fertilizers also help increase the organic matter content in the soil, further enhancing the fertility of the soil.

[0003] In fertilizer production, it is necessary to put the fertilizer mixed with the binder into the extrusion equipment, and use the extrusion equipment to produce fine-grained fertilizer. At present, there are few types of extrusion equipment for fertilizers. For example, a Chinese patent with patent number CN217796317U provides a fertilizer extruder, which includes: a support frame, a squeezing roller and a motor are installed on the top of the support frame; a filter plate, a fixed plate is installed on the top of the filter plate, a plug-in plate is plugged into the top of the fixed plate, a brush is installed on the top of the plug-in plate, a push plate is installed at the bottom of the filter plate, and a screw is provided at the bottom of the push plate; and a discharge port, which is provided on the outer wall of the support frame; the beneficial effect is that the filter plate is installed inside the support frame proposed by the present invention, the fixed plate is installed on the top of the filter plate, the plug-in plate is plugged into the top of the fixed plate, the brush on the top of the plug-in plate can clean the fertilizer on the surface of the squeezing roller, and after the fertilizer falls on the top of the filter plate, the granulated fertilizer is discharged through the discharge port, and the non-granulated fertilizer falls from the bottom of the support frame, and the height of the filter plate can be adjusted by rotating the screw, so that after the brush is worn, the filter plate can be raised so that the brush can still clean the surface of the squeezing roller.

[0004] The equipment provided by the aforementioned patent primarily relies on the rotation of an extrusion roller to squeeze the raw material into the curved grooves of the extrusion rollers. With the cooperation of the two extrusion rollers, the raw material forms granules in the two curved grooves. However, the structural characteristics of the extrusion rollers limit the size of the granules. Because the two extrusion rollers come into line contact when extruding into granules, this is not conducive to producing dense fertilizer granules with a large diameter. However, small-particle fertilizers release nutrients quickly, and their fertilizer efficiency cannot meet the needs of crops with long growth cycles. For example, fruit trees require fertilizer from germination to fruiting to maturity. Currently, fertilization is mostly done manually, with baskets carried across the orchard. This is inefficient and causes fatigue for workers. If the fertilizer granules are enlarged and made into large-particle fertilizer products, the nutrients can be released slowly, meeting the long-term nutrient needs of crops to a certain extent.

[0028] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0029] Example 1

[0030] In order to produce fertilizers with larger particles and meet the nutrient requirements of crops with longer growth cycles, this embodiment provides a fertilizer production device, the specific structure of which is shown below.

[0031] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 、 Figure 8As shown, the manufacturing device includes a support frame 1, an extrusion mechanism 2, and an extrusion fitting 4. The support frame 1 includes a support frame 11, a flat plate 12, and a vertical plate 14. The flat plate 12 is laid on the support frame 11, and the vertical plate 14 is vertically arranged above the support frame 11. A horizontal plate is arranged between the two vertical plates 14, and a first telescopic cylinder 15 is arranged on the horizontal plate. The first telescopic cylinder 15 is arranged in an inverted manner. Mounting holes 13 are provided in the middle of the flat plate 12 and the support frame 11. The extrusion fitting 4 is provided at the mounting hole 13. The extrusion fitting 4 is detachably connected to the support frame 11. A filling hole 41 is provided on the extrusion fitting 4, and a bottom plate 43 is adjustable below. The bottom plate 43 is provided with a second curved groove 44, which is arranged to communicate with the filling hole 41 and is arranged to face the second curved groove 44. Furthermore, the extrusion mechanism 2 is positioned directly above the extrusion fitting 4 and comprises a top plate 21 and multiple extrusion rods 22. The top plate 21 is removably mounted at the lower end of the first telescopic cylinder 15. The extrusion rods 22 are positioned perpendicularly below the top plate 21 and have a first curved groove 23 on their lower end surface. The lower ends of the extrusion rods 22 can be inserted into the filling hole 41. The second curved groove 44 and the first curved groove 23 cooperate to form a spherical space. To produce large, dense fertilizer granules using this device, fertilizer material is injected into the filling hole 41. The first telescopic cylinder 15 operates to control the top plate 21, driving the multiple extrusion rods 22 downward. Under the pressure of the extrusion rods 22, the fertilizer material contracts within the spherical space. This compression, coupled with the first curved groove 23 and the second curved groove 44, forms dense fertilizer granules. After the fertilizer granules are formed, the bottom plate 43, under the action of an external force, rotates about its axis to an inclined position until the fertilizer granules are released from the bottom plate 43. After the fertilizer particles are separated, the bottom plate 43 is reset and cooperates with the extrusion fitting 4 and the extrusion mechanism 2 to provide support for making large-sized sealed fertilizer particles again.

[0032] like Figure 6 As shown, in order to realize the rotation of the bottom plate 43, the bottom plate 43 and the edge of the extrusion fitting 4 are connected by a hinge. In addition, a second telescopic cylinder 42 is hingedly provided on the side of the extrusion fitting 4 through a bracket. The second telescopic cylinder 42 is tilted and arranged on the side below the bottom plate 43, and the top is hingedly connected to the lower side of the bottom plate 43. Therefore, under the action of the second telescopic cylinder 42, the bottom plate 43 can be controlled to rotate around the hinge bearing, which provides convenience for the fertilizer particles.

[0033] like Figure 2 、 Figure 5As shown in the figure, in order to achieve the detachable connection between the extrusion mechanism 2 and the first telescopic cylinder 15, a fixed arc plate 24 and a clamping arc plate 25 are provided in the middle above the top plate 21. The fixed arc plate 24 is fixedly connected to the top plate 21, and the clamping arc plate 25 is connected to the fixed arc plate 24 by bolts. In addition, the telescopic end of the first telescopic cylinder 15 extends into the space formed by the clamping arc plate 25 and the fixed arc plate 24, realizing the detachable connection between the top plate 21 and the first telescopic cylinder 15. In order to stably install the top plate 21 relative to the first telescopic cylinder 15, an arc-shaped groove is provided at the lower end of the first telescopic cylinder 15, and an arc-shaped protrusion 26 is provided on the inner side wall of the fixed arc plate 24. The arc-shaped protrusion 26 extends into the arc-shaped groove. Therefore, the cooperation between the arc-shaped protrusion 26 and the arc-shaped groove increases the resistance of the first telescopic cylinder 15 to move relative to the top plate 21.

[0034] As Figure 6 , Figure 7 shown in the figure, in order to stably connect the extrusion fitting 4 and the support frame 11, a fixing plate 54 is fixedly provided on the lower side surface of the support frame 11. An adjusting screw rod 52 is threadedly penetrated through the fixing plate 54, and a convex column 55 is fixedly provided at the end. An insertion frame 51 is provided outside the fixing plate 54. The insertion frame 51 is arranged in a U-shaped structure, and a sliding groove 53 is provided on the inner side wall. The fixing plate 54 is located inside the insertion frame 51, and the convex column 55 extends into the sliding groove 53, realizing the movable detachable connection between the fixing plate 54 and the insertion frame 51. The end of the adjusting screw rod 52 is inserted into the insertion frame 51 through a bearing connection. Therefore, by rotating the adjusting screw rod 52, the relative movement of the fixing plate 54 and the insertion frame 51 can be controlled, and the position of the insertion frame 51 relative to the support frame 11 can be changed. In addition, a slot is provided on the side wall of the extrusion fitting 4, and the end of the insertion frame 51 is inserted into the slot, supporting the stable installation of the extrusion fitting 4, and at the same time facilitating the disassembly and replacement of the extrusion fitting 4 according to requirements, and facilitating the manufacture of fertilizer particles with different diameters.

[0035] Embodiment 2

[0036] As Figure 1 , Figure 9As shown, based on Example 1, in order to achieve continuous production of fertilizer granules, a pusher frame 3 is provided above the flat plate 12. The inner width of the pusher frame 3 is equal to the width of the extrusion fitting 4, and the length is greater than the length of the extrusion fitting 4. Therefore, by pushing the pusher frame 3 to move, the fertilizer raw materials inside the pusher frame 3 can be driven to move, and during the movement process, part of the fertilizer falls into the filling hole 41. In order to ensure the stable installation of the pusher frame 3, a limiting frame 32 is provided at the bottom of one side of the pusher frame 3, and a transmission belt 33 is connected to the other side. The two ends of the transmission belt 33 are mounted on the pulley, and the central axis of one pulley is connected to the output shaft of the motor. A limiting plate 31 is provided through the limiting frame 32, and the end of the limiting plate 31 is connected to the flat plate 12 by a bolt. This arrangement can limit the movement of the pusher frame 3 in contact with the flat plate 12. In addition, when the transmission belt 33 rotates, the movement of the pusher frame 3 can be controlled to provide support for pushing the fertilizer raw materials to move.

For those skilled in the art, various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
