Abstract
Description
Technical Field
[0001] This utility model relates to the field of fertilizer granulation technology, and in particular to an organic fertilizer granulation device for rice cultivation. Background Technology
[0002] Organic fertilizers are typically used in rice cultivation. Organic fertilizers are a type of fertilizer produced by the decomposition or fermentation of organic matter by microorganisms. Organic fertilizers are widely available, contain a complete range of nutrients, and have a long-lasting effect, making them popular among growers. At the same time, organic fertilizers can provide plants with most of the nitrogen and potassium elements needed for growth, and are also a source of carbon nutrients required by crops. Usually, to make fertilization more convenient, organic fertilizers need to be granulated into granules using a granulation device.
[0003] Existing organic fertilizer granulation devices for rice cultivation have a significant functional shortcoming in the fertilizer granulation process—the lack of a supporting drying mechanism. This deficiency leads to high moisture content in the granulated fertilizer granules, making them prone to agglomeration and sticking during subsequent storage or transportation. Specifically, when fertilizer granules are stacked, the capillary force generated by moisture migration between granules causes clumping, resulting in the originally independent granule structures sticking together into clumps. This physical change not only affects the bulk flowability of the fertilizer but also significantly increases the difficulty of subsequent fertilization operations—whether by manual spreading or mechanical scattering, the agglomerated fertilizer granules are difficult to disperse evenly. Therefore, this application provides an organic fertilizer granulation device for rice cultivation to meet this need. Utility Model Content
[0004] The technical problem this invention aims to solve is to provide a granulation device for organic fertilizer used in rice cultivation. This addresses the significant functional shortcomings of existing granulation devices for organic fertilizer used in rice cultivation during the fertilizer granulation process—the lack of a supporting auxiliary drying mechanism. This deficiency leads to high moisture content in the granulated fertilizer granules, making them prone to agglomeration and adhesion during subsequent storage or transportation. Specifically, when fertilizer granules are stacked, the capillary force generated by moisture migration between granules causes clumping, resulting in the originally independent granular structures sticking together into clumps. This physical change not only affects the bulk flowability of the fertilizer but also significantly increases the difficulty of subsequent fertilization operations—whether by manual spreading or mechanical scattering, the agglomerated fertilizer granules are difficult to disperse evenly.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] An organic fertilizer granulation device for rice cultivation includes an extrusion preparation cylinder, a base frame fixed at the bottom of the extrusion preparation cylinder, an extrusion chamber inside the extrusion preparation cylinder, a spiral extrusion shaft installed in the extrusion chamber, a servo motor for driving the spiral extrusion shaft to rotate installed on one side of the extrusion preparation cylinder, a collection funnel installed at the top of the extrusion preparation cylinder, the collection funnel communicating with the extrusion chamber, a mounting base installed at the end of the extrusion preparation cylinder away from the servo motor, an extrusion plate installed on the mounting base, and a collection box installed on the side of the extrusion preparation cylinder corresponding to the mounting base.
[0007] The collection box has an opening for mounting the mounting base, and a drying chamber is provided inside the collection box. A heating and drying plate is hinged in the drying chamber, and a top pressure assembly that drives the heating and drying plate is installed on the side of the collection box.
[0008] Preferably, the top of the heating and drying plate has several serrated grooves, and a heating tube is installed inside the heating and drying plate in an S-shape.
[0009] Preferably, the top pressure assembly includes a slide rod hinged to the side of the collection box and the bottom of the heating and drying plate. Two slide rods are installed in a sleeve, and a cavity is provided inside the sleeve. A buffer spring for supporting the slide rod is installed in the cavity.
[0010] Preferably, the collection box has a slag discharge port at the bottom and a material discharge port at an angle on the side.
[0011] Preferably, a screening screen is installed at an angle at the bottom of the collection box corresponding to the discharge port, and a vibration motor is installed at the bottom of the screening screen.
[0012] Preferably, a fixing ring is fixed at the outer edge of the collection box, and fixing holes are drilled on both the extrusion preparation cylinder and the fixing ring. The two fixing holes are positioned and fastened by bolts.
[0013] Preferably, the extrusion disc has a plurality of extrusion openings, and a pelletizing knife is rotatably mounted on the extrusion disc.
[0014] Preferably, a protruding block is provided at the outer edge of the extrusion disc, and a snap-fit cavity is provided on the mounting base, in which the protruding block is snap-fitted and installed.
[0015] Preferably, the protruding block has a positioning hole, and a positioning component that engages with the positioning hole is installed in the snap-fit cavity.
[0016] Preferably, the positioning component includes a positioning pin slidably disposed in the snap-fit cavity, a sliding rod vertically fixed at the top of the positioning pin, the bottom of the positioning pin being inserted into a positioning hole, and a top pressure spring being sleeved on the top of the positioning pin corresponding to the sliding rod.
[0017] Compared with the prior art, this utility model has at least the following beneficial effects:
[0018] In the above scheme, through the cooperation between the collection box set on the extrusion preparation cylinder and the heating and drying plate set inside it, the fertilizer particles fall into the heating and drying plate, and the heating and drying plate is heated as a whole by the heating pipe on the heating and drying plate. When the fertilizer particles fall onto the heated and drying plate, the fertilizer particles undergo auxiliary drying treatment. The fertilizer particles fall as a whole along the inclined heating and drying plate, and through the serrated groove on the top of the heating and drying plate, the fertilizer particles can be tumbled as they fall. This can effectively reduce the moisture content in the fertilizer particles in subsequent work and minimize the phenomenon of agglomeration and adhesion between fertilizer particles in subsequent storage or transportation.
[0019] By coordinating the screening screen and the vibrating motor, the dried fertilizer granules fall to the top of the screening screen after the drying process begins. The vibrating motor then drives the screening screen to vibrate, thus assisting in the screening of the dried fertilizer granules and minimizing the possibility of the granules becoming loose and unsuitable for subsequent fertilization.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, an embodiment of the present invention provides a pelleting device for organic fertilizer used in rice cultivation, including an extrusion preparation cylinder 1, a base frame 4 fixed at the bottom of the extrusion preparation cylinder 1, an extrusion chamber inside the extrusion preparation cylinder 1, a spiral extrusion shaft installed in the extrusion chamber, a servo motor 2 for driving the spiral extrusion shaft to rotate on one side of the extrusion preparation cylinder 1, a collection funnel 3 installed at the top of the extrusion preparation cylinder 1, the collection funnel 3 communicating with the extrusion chamber, a mounting base 5 installed at the end of the extrusion preparation cylinder 1 away from the servo motor 2, an extrusion disc 6 installed on the mounting base 5, a plurality of extrusion ports 7 opened on the extrusion disc 6, a pelletizing knife 8 rotatably mounted on the extrusion disc 6, and a rotating motor for driving the pelletizing knife 8 to rotate installed inside the extrusion disc 6.
[0034] A collection box 13 is installed on the side of the mounting base 5 corresponding to the extrusion preparation cylinder 1. A fixing ring 15 is fixed to the outer edge of the collection box 13. Fixing holes 14 are drilled on both the extrusion preparation cylinder 1 and the fixing ring 15. The two fixing holes 14 are fixed together by bolts. The collection box 13 has a receiving opening for the mounting base 5 to be installed. A drying chamber is opened inside the collection box 13. A heating drying plate 16 is hinged in the drying chamber. Several grooves 17 are serrated at the top of the heating drying plate 16. A heating tube 18 is installed inside the heating drying plate 16. The heating tube 18 is S-shaped and installed inside the heating and drying plate 16. The heating tube 18 is an electric heating tube. The side of the collection box 13 is equipped with a top pressure assembly 19 that supports the heating and drying plate 16. In actual operation, the top pressure assembly 19 can use an electric push rod to control the overall tilt angle of the heating and drying plate 16. The top pressure assembly 19 includes a slide rod 20 that is hinged to the side of the collection box 13 and the bottom of the heating and drying plate 16. The two slide rods 20 are installed in the sleeve 21. The sleeve 21 has a cavity inside, and a buffer spring 22 that supports the slide rods 20 is installed in the cavity.
[0035] Through the cooperation between the collection box 13 set on the extrusion preparation cylinder 1 and the heating and drying plate 16 set inside it, the fertilizer particles fall into the heating and drying plate 16, and the heating and drying plate 16 is heated as a whole by the heating pipe 18 on the heating and drying plate 16. When the fertilizer particles fall onto the heated and drying plate 16 and undergo auxiliary drying treatment, the fertilizer particles fall as a whole along the inclined heating and drying plate 16. Through the serrated groove 17 on the top of the heating and drying plate 16, the fertilizer particles can be tumbled as they fall, which can effectively reduce the moisture content in the fertilizer particles in subsequent work and minimize the phenomenon of agglomeration and adhesion between fertilizer particles in subsequent storage or transportation.
[0036] The collection box 13 has a slag discharge port at the bottom and a material discharge port on the side of the collection box 13. A screening screen 23 is installed at an angle at the bottom of the collection box 13 corresponding to the material discharge port, and a vibration motor 24 is installed at the bottom of the screening screen 23.
[0037] Through the coordination of the screening screen 23 and the vibrating motor 24, after the drying process, the dried fertilizer granules fall to the top of the screening screen 23. The vibrating motor 24 is then activated, causing the screening screen 23 to vibrate, thus assisting in the screening of the dried fertilizer granules and minimizing the possibility of the granules becoming loose and unsuitable for subsequent fertilization.
[0038] like Figure 2 and Figure 4As shown, a protruding block 61 is provided at the outer edge of the extrusion disc 6. A snap-fit cavity is provided on the mounting base 5. The protruding block 61 is snap-fitted in the snap-fit cavity. A positioning hole 62 is provided on the protruding block 61. A positioning component 9 is installed in the snap-fit cavity and is engaged with the positioning hole 62. The positioning component 9 includes a positioning pin 12 that is slidably disposed in the snap-fit cavity. A sliding rod 10 is vertically fixed at the top of the positioning pin 12. The bottom of the positioning pin 12 is inserted into the positioning hole 62. A top pressure spring 11 is sleeved on the top of the positioning pin 12 corresponding to the sliding rod 10.
[0039] By setting up a detachable extrusion disc 6 and cooperating with protruding blocks 61 and positioning components 9, pulling the sliding rod 10 causes the positioning pin 12 to be pulled and the top pressure spring 11 to be compressed, inserting the protruding block 61 into the snap-fit cavity. Releasing the sliding rod 10 allows the positioning pin 12 to be inserted into the positioning hole 62 under the action of the compressed top pressure spring 11, enabling the quick disassembly of the extrusion disc 6. This facilitates the production of fertilizer granules of different sizes and improves the overall practicality of the device.
[0040] The working principle of the technical solution provided by this utility model is as follows:
[0041] When the extrusion disc 6 needs to be installed, pull the sliding rod 10. The sliding rod 10 will pull the positioning pin 12 and compress the top pressure spring 11, inserting the protruding block 61 into the snap-fit cavity. Release the sliding rod 10, and under the action of the compressed top pressure spring 11, insert the positioning pin 12 into the positioning hole 62. Start the servo motor 2, which will drive the spiral extrusion shaft to rotate as a whole. When the spiral extrusion shaft rotates, it will drive the raw material to be extruded through the extrusion port 7 on the extrusion disc 6. Start the rotation motor, which will drive the pelletizing knife 8 to rotate as a whole. When the pelletizing knife 8 rotates, it will drive the extruded raw material to undergo auxiliary pelletizing.
[0042] After being granulated, the fertilizer pellets fall into the collection box 13 and then into the heating and drying plate 16. The heating and drying plate 16 is heated by the heating tubes 18 on it. As the fertilizer pellets fall onto the heated and drying plate 16 and undergo auxiliary drying, they fall along the inclined heating and drying plate 16. The serrated grooves 17 on the top of the heating and drying plate 16 help to tumble the pellets as they fall. The downward pressure generated by the falling pellets causes the heating and drying plate 16 to swing downwards, which in turn causes the top pressure assembly 19 to retract. The compression and extension of the buffer spring 22 inside the top pressure assembly 19 enables the heating and drying plate 16 to swing up and down.
[0043] The dried fertilizer granules fall to the top of the screening screen 23. The vibration motor 24 is started, which drives the screening screen 23 to vibrate, thereby performing auxiliary screening of the dried fertilizer granules.

To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.
[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
