Description

Technical Field

[0001] This patent relates to the field of fertilizer granulation technology, specifically a granulation mechanism for fast-growing grass charcoal-based slow-release ecological fertilizer. Background Technology

[0002] Fertilizer refers to a type of substance that provides one or more essential nutrients for plants, improves soil properties, and enhances soil fertility. It is one of the material bases of agricultural production. Fast-growing grass charcoal-based slow-release ecological fertilizer is an ecological fertilizer made by mixing slow-release components with charcoal-based components. It can rapidly degrade and balance the soil pH by the charcoal-based part of the slow-release fertilizer, which has the advantages of releasing fertilizer while balancing soil pH.

[0003] A granulator is a molding machine that can shape materials into specific shapes. When granulating fertilizer, the fertilizer is fed into the feed cylinder and then squeezed and granulated by two relatively rotating rollers inside the machine.

[0004] However, existing granulation mechanisms have poor granulation efficiency. They generally require sieving after granulation and then extruding the unformed granules again, which is cumbersome and time-consuming. Utility Model Content

[0005] The purpose of this patent is to provide a granulation mechanism for fast-growing grass charcoal-based slow-release ecological fertilizer to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this patent provides the following technical solution: a granulation mechanism for fast-growing grass charcoal-based slow-release ecological fertilizer, comprising a fertilizer feeding hopper and a granulation box, wherein the fertilizer feeding hopper is inserted and installed inside the granulation box, and a quantitative feeder is installed on the upper wall of the fertilizer feeding hopper, wherein the quantitative feeder is filled with fast-growing grass charcoal-based slow-release ecological fertilizer;

[0007] The granulation chamber has a granulation mechanism installed inside. An air jet pipe and a spray head are inserted into the side wall of the granulation chamber. The air jet pipe is located below the granulation mechanism and is connected to an external air pump. A water supply pipe is installed at one end of the spray head located outside the granulation chamber and is connected to an external water pump. The spray head is located above the granulation mechanism. Both the airflow output from the air jet pipe and the water mist output from the spray head can act on the surface of the granulation mechanism.

[0008] Preferably, the granulation mechanism includes a connecting shaft, a rotating roller, and a hemispherical groove. The connecting shaft is rotatably mounted on the inner side wall of the granulation box. There are two connecting shafts in total. Both connecting shafts pass through the side wall of the granulation box and are connected to the output end of an external motor. Rotating rollers are mounted on the outer sides of the two connecting shafts. Hemispherical grooves are formed on the outer side walls of the two rotating rollers. The positions of the hemispherical grooves on the outer side walls of the two rotating rollers correspond to each other.

[0009] Preferably, the inner sidewall of the granulation box is equipped with two cleaning brushes, which are respectively attached to the sidewalls of the two rotating rollers.

[0010] Preferably, the granulation box has a discharge port on its side wall and a sieve plate is installed on the inner wall of the granulation box. The sieve plate is inclinedly arranged inside the granulation box and penetrates the side wall of the granulation box through the discharge port.

[0011] Preferably, the lower wall of the granulation box is provided with a powder discharge port.

[0012] Preferably, the cleaning brush includes a convex plate, a groove, a sliding block, a spring, and bristles. The convex plate is installed on the inner wall of the granulation box. The lower wall of the convex plate has a groove. The sliding block is slidably installed in the groove. One end of the spring is installed on the upper wall of the sliding block. The other end of the spring is in contact with the inner wall of the groove. The lower wall of the sliding block is equipped with bristles.

[0013] Compared with existing technologies, the beneficial effects of this patent are:

[0014] This device uses a spray head above its granulation mechanism to spray water mist onto the organic fertilizer entering the granulation box through the fertilizer feed hopper, increasing its humidity and making it easier to form after extrusion, thus improving the granulation efficiency of the device. At the same time, an air jet pipe is installed below the granulation mechanism to blow air onto the granulation mechanism, causing the fertilizer adhering to the granulation mechanism to fall off under the action of airflow.

Detailed Implementation

[0019] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0020] Please see Figure 1-3 This patent provides a technical solution: a granulation mechanism for fast-growing grass charcoal-based slow-release ecological fertilizer, including a fertilizer feeding hopper 1 and a granulation box 2. The fertilizer feeding hopper 1 is inserted and installed in the granulation box 2. A quantitative feeder 3 is installed on the upper wall of the fertilizer feeding hopper 1. The quantitative feeder 3 is filled with fast-growing grass charcoal-based slow-release ecological fertilizer.

[0021] The fast-growing grass charcoal-based slow-release ecological fertilizer proposed in this article is an existing technology that can be purchased directly on the market. This ecological fertilizer is a mixture of slow-release components and charcoal-based components. It can rapidly degrade and balance the soil pH by the charcoal-based part of the slow-release fertilizer, which has the advantages of releasing fertility while balancing the soil pH.

[0022] The slow-release components include urea, slow-release nitrogen, slow-release phosphorus, slow-release potassium, trace elements, pH adjusters, and biological additives. The carbon-based components include fast-growing peat moss and organic acids.

[0023] In this device, the fast-growing grass char-based slow-release ecological fertilizer is fed into the granulation box 2 by the quantitative feeder 3, so that the feed amount of the fast-growing grass char-based slow-release ecological fertilizer can be controlled to avoid excessive feed amount causing fertilizer accumulation, which would cause the fertilizer to flow down from both sides of the granulation mechanism 4 without being squeezed into shape.

[0024] The granulation chamber 2 is equipped with a granulation mechanism 4. A jet pipe 5 and a spray head 6 are inserted into the side wall of the granulation chamber 2. The jet pipe 5 is located below the granulation mechanism 4 and is connected to an external air pump. A water supply pipe 7 is installed at one end of the spray head 6 located outside the granulation chamber 2 and is connected to an external water pump. The spray head 6 is located above the granulation mechanism 4. The airflow output from the jet pipe 5 and the water mist output from the spray head 6 can both act on the surface of the granulation mechanism 4.

[0025] Water mist is sprayed from the spray head 6 and acts on the organic fertilizer that enters the granulation box 2 through the fertilizer feed hopper 1, increasing its humidity and making it easier for the organic fertilizer to be shaped after extrusion, thus improving the granulation efficiency of the device. At the same time, an air jet pipe 5 is also installed below the granulation mechanism 4. Air is blown into the granulation mechanism 4 through the air jet pipe 5, causing the fertilizer granules adhering to the granulation mechanism 4 to be blown off by the airflow.

[0026] Specifically, the granulation mechanism 4 includes a connecting shaft 41, a rotating roller 42, and a hemispherical groove 43. The connecting shaft 41 is rotatably mounted on the inner side wall of the granulation box 2. There are two connecting shafts 41. Both connecting shafts 41 pass through the side wall of the granulation box 2 and are connected to the output end of an external motor. The rotating roller 42 is mounted on the outer side of both connecting shafts 41. The outer side wall of the two rotating rollers 42 is provided with a hemispherical groove 43. The positions of the hemispherical grooves 43 on the outer side wall of the two rotating rollers 42 correspond to each other.

[0027] The two connecting shafts 41 rotate in opposite directions, allowing them to compress the organic fertilizer through the two rotating rollers 42. At the same time, the hemispherical grooves 43 on the two rotating rollers 42 are positioned in opposite directions, so that they can form a complete sphere, making the extruded fertilizer particles spherical.

[0028] Specifically, two cleaning brushes 8 are installed on the inner side wall of the granulation box 2, and the two cleaning brushes 8 are respectively attached to the side walls of the two rotating rollers 42.

[0029] The cleaning brush 8 can clean its rotating wheel 42 and hemispherical groove 43, making it more convenient to clean the device after use.

[0030] Specifically, the side wall of the granulation box 2 is provided with a discharge port 9, and the inner wall of the granulation box 2 is provided with a screen plate 10. The screen plate 10 is inclinedly arranged inside the granulation box 2 and passes through the side wall of the granulation box 2 through the discharge port 9.

[0031] The sieve plate 10 can screen the formed ecological fertilizer granules, and screen out the unformed fertilizer that is still in powder form. The fertilizer is then discharged through the powder discharge port 11 below. The staff can then feed the powder back into the quantitative feeder 3 and then granulate it again through the granulation mechanism 4. The screened fertilizer granules will be discharged from the granulation box 2 through the discharge port 9 via the sieve plate 10.

[0032] Specifically, the lower wall of the granulation box 2 is provided with a powder discharge port 11.

[0033] Specifically, the cleaning brush 8 includes a convex plate 81, a groove 82, a sliding block 83, a spring 84, and bristles 85. The convex plate 81 is installed on the inner wall of the granulation box 2. The lower wall of the convex plate 81 has a groove 82. The sliding block 83 is slidably installed in the groove 82. One end of the spring 84 is installed on the upper wall of the sliding block 83. The other end of the spring 84 is in contact with the inner wall of the groove 82. The lower wall of the sliding block 83 has bristles 85 installed.

[0034] By setting the bristles 85 on the sliding block 83, the spring 84 can provide a pushing force to the sliding block 83, thereby allowing the bristles 85 to fit against the rotating roller 42, ensuring the cleaning effect of the cleaning brush 8.

[0035] Working principle: The fast-growing grass charcoal-based slow-release ecological fertilizer is fed into the fertilizer feed hopper 1 by the quantitative feeder 3, and then falls into the granulation box 2 above the granulation mechanism 4. At this time, the external motor drives the two connecting shafts 41 to rotate, so that the two rotating wheels 42 rotate relative to each other and compress the ecological fertilizer. At the same time, the hemispherical grooves 43 on the two rotating wheels 42 are positioned to correspond to each other, so that they can form a complete sphere, so that the fertilizer granules extruded are spherical.

[0036] During this process, an external water pump supplies water to the spray head 6 through the water pipe 7, and then sprays it out through the spray head 6 to form a water mist, which increases the humidity of the fertilizer and makes it easier for the fertilizer to be shaped after being squeezed. At the same time, air is blown into the granulation mechanism 4 through the air jet pipe 5, which blows off the fertilizer particles that are stuck on the granulation mechanism 4 under the action of the airflow.

[0037] After the organic fertilizer granules are formed, they are screened through the screen plate 10 to screen out the unformed, powdery fertilizer and discharge it through the powder discharge port 11 below. Then, the staff can put the powder back into the quantitative feeder 3 and then granulate it again through the granulation mechanism 4. The screened fertilizer granules will be discharged from the granulation box 2 through the discharge port 9 through the screen plate 10.

[0038] It will be apparent to those skilled in the art that this patent is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this patent. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this patent is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this patent. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
