Description

Technical Field

[0001] The invention relates to the technical field of granular fertilizers, in particular to a rice-grain type granular fertilizer, a fertilizer making machine and a fertilizer making method thereof. Background Art

[0002] Granular fertilizer, also known as granular water-soluble fertilizer, is a granular compound water-soluble fertilizer that can be completely dissolved in water. Granular fertilizer is made of chemical fertilizers such as superphosphate or ammonium nitrate, or a granular fertilizer made of a mixture of organic fertilizer and superphosphate.

[0003] Granular fertilizers usually contain a variety of nutrients such as nitrogen, phosphorus, potassium, as well as trace elements and amino acids, which can meet the needs of plants at different growth stages. In the prior art, granular fertilizers are mostly spherical or ellipsoidal structures. When the new root system of a plant stretches, it does not need to absorb a large amount of nutrients from the fertilizer. Granular fertilizers with spherical or ellipsoidal structures release nutrients excessively, and the new root system of the plant cannot fully absorb them, resulting in waste. It will also cause waste of fertilizers, resulting in a short fertilizer effect period for the granular fertilizer, which cannot meet the nutrient needs of the plant during the rapid growth period. In addition, the granulator directly sends the stirred raw materials directly into the rolling mold for rolling forming, but the rolled particles are not full and are easily mixed with bubbles, resulting in a fast release speed of the granular fertilizer in the soil, insufficient nutrients, and cannot meet the needs of plant root growth.

DETAILED DESCRIPTION

[0039] The following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Embodiment 1, this embodiment provides a kind of rice grain type granular fertilizer, such as Figure 1 As shown, it includes granular fertilizer, the two ends of the granular fertilizer are pointed narrowing parts 1A, and the middle is a thickening part 1; and the two pointed narrowing parts 1A and the thickening structure are continuously connected to form a rice grain-shaped structure.

[0041] Specifically, the two-pointed narrowed parts 1A of the granular fertilizer gradually become thicker toward the thickened part 1. The two-pointed design is adopted to allow the new roots of the plant to slowly adapt and absorb nutrients. When the new roots of the plant extend, a small amount of nutrients is needed. At this time, the nutrients in the two-pointed narrowed parts are slowly released in the soil, which is timely and beneficial to adapt to the absorption and utilization of the new roots of the plant.

[0042] The thickened portion 1 in the middle of the granular fertilizer is designed so that the plant will need more nutrients during the absorption and growth period. The narrowed portions 1A at both ends of the granular fertilizer have been completely released during the period of the plant's new root system, and are absorbed and digested by the plant's new root system. At this time, the thickened portion 1 will continue to release nutrients, which can further provide the nutrients needed for plant growth.

[0043] The characteristic of the above-mentioned rice-grain-shaped granular fertilizer is that it can be used in the process of plant growth from small to large, slowly release nutrients in the soil, and more effectively meet the needs of plants for absorbing fertilizer nutrients as they grow from small to large.

[0044] In addition, according to the growth stages of different plants, the granular fertilizer with a rice-grain structure can be divided into multiple levels from the tip-contracted portion 1A to the thickened portion 1 at both ends, with the tip-contracted portion 1A at the first level, then the second level, the third level, and the thickened portion 1 in the middle. Of course, more levels can be set. The so-called multi-stage design is that the middle part from the tip-contracted portion 1A to the thickened portion 1 is more slender, which prolongs the time it takes for the granular fertilizer to release nutrients.

[0045] Embodiment 2, this embodiment discloses a fertilizer making machine, which is used to make the rice-grain type granular fertilizer of claim 1, such as Figure 2 As shown, it includes: a body 2, a base 3 is arranged under the body 2, and the base 3 is used to stably support the body 2.

[0046] At the same time, a hollow fertilizer making chamber is provided in the machine body 2, a feed hopper 21 is provided at the upper end of the machine body 2, a smooth roller 7, a granulating roller 4 and a scattering roller 5 are rotatably arranged in the hollow fertilizer making chamber, the smooth roller 7, the granulating roller 4 and the scattering roller 5 are arranged parallel to each other, and are arranged in sequence from top to bottom. Specifically, both axial ends of the granulating roller 4 are open structures, and a transmission disk 42 is inserted in the open structure, a clamping notch 44 is provided at the edge of the side wall of the transmission disk 42, and a convex block 43 that is clamped with the clamping notch 44 is provided on the inner wall of the opening structure, such as Figure 3 As shown, when the transmission disc 42 is inserted into the opening structure, the protrusion 43 is engaged with the engaging notch 44 to ensure that when the transmission disc 42 rotates, the granulating roller 4 can be driven to rotate synchronously. The side walls of the end of the smooth roller 7, one of the transmission discs 42 and the scattering roller 5 are all fixed with a transmission rod that rotates and penetrates the side wall of the machine body 2. The end of the transmission rod is fixed with a pulley, and the outer walls of the three pulleys are provided with a transmission belt 10. Figure 2 and Figure 4 As shown, it also includes a power device 6, which has a reduction motor. The output end of the reduction motor is fixedly connected to one of the pulleys to provide rotational power. When the pulley rotates, it is transmitted through the transmission belt 10, and the other pulleys rotate synchronously, thereby driving the smooth roller 7, the transmission disk 42, the granulating roller 4 and the scattering roller 5 to rotate synchronously.

[0047] A discharge port 1 22 and a discharge port 23 are provided on the side wall of the machine body 2 , wherein the rolling gap is arranged horizontally opposite to the discharge port 1 22 ; and the breaking gap is arranged horizontally opposite to the discharge port 23 .

[0048] like Figure 4As shown, a rolling gap is provided between the smooth roller 7 and the granulating roller 4. The smooth roller 7 can roll the fertilizer raw material to form a cake-strip structure fertilizer, and the cake-strip structure fertilizer is output from the discharge port 1 22. A granulating gap is provided between the granulating roller 4 and the scattering roller 5. A plurality of evenly arranged rice-shaped die holes 41 are provided on the radial side wall of the granulating roller 4. The rolled cake-strip structure fertilizer is fed into the granulating gap again from the discharge port 1 22. The granulating roller 4 can roll the cake-strip structure fertilizer to form granules when it rolls. At the same time, the scattering roller 5 is used to scatter the rolled granules to form granular fertilizer, and the granular fertilizer can be output through the discharge port 2 23.

[0049] In summary, the above structure adopts the method of first rolling the fertilizer into a cake strip structure and then granulating it, which ensures that there are no bubbles in the finished fertilizer, and can quickly process and batch produce rice-grain granular fertilizer to meet the root nutrient needs of plants in the early and late stages of growth.

[0050] In order to ensure the effectiveness of the transmission power, a pulley connected to a transmission rod corresponding to the transmission disc 42 is set as a large wheel 9, and a pulley connected to the transmission rod corresponding to the smooth roller 7 and the scattering roller 5 is set as a small wheel 8. Figure 5 As shown, the pulley located in the middle position is the large wheel 9, so that the middle section of the transmission belt 10 can be expanded and supported, ensuring that the transmission belt 10 is in close contact with the outer walls of all the pulleys, avoiding a gap between the transmission belt 10 and the outer wall of the large wheel 9 in the middle position, resulting in transmission failure.

[0051] In addition, a plurality of rows of scattering teeth 51 are provided on the radial outer wall of the scattering roller 5, and a plurality of single-row scattering teeth 51 are provided and are distributed at intervals, such as Figure 4 As shown, when the scattering roller 5 rotates, multiple rows of scattering teeth 51 can be used to rotate synchronously, and the rice-type particles rolled by the granulating roller 4 can be scattered. The inner wall of the hollow fertilizer making chamber is also fixed with a screen 52 wrapped around the outside of the scattering teeth 51. The side view cross-section of the screen 52 is a U-shaped structure, and the outer wall of the screen 52 is provided with a plurality of sieve holes, such as Figure 6 and Figure 7 As shown, the screen 52 carries the particles that stick together after granulation, and the particles are broken up by the rotating breaking teeth 51, and fall through the screen holes with a larger aperture than the granular fertilizer to the bottom of the hollow fertilizer making chamber. Figure 8 As shown, the breaking teeth 51 may adopt an isosceles trapezoidal structure design in addition to a columnar structure, the purpose of which is also to drive the granulated fertilizer to creep on the screen 52 and break it up.

[0052] In this embodiment, further, Figure 2 As shown, a push drawer 24 located just below the scattering roller 5 is slidably inserted into the second discharge port 23. By pulling out the push drawer 24, the scattered rice-grain granular fertilizer can be drawn out and collected in a centralized manner.

[0053] Embodiment 3, this embodiment discloses a method for making rice-grain granular fertilizer, using a fertilizer making machine, comprising the following steps:
