Description

Technical Field

[0001] The present invention belongs to the technical field of biological fertilizer production, and particularly relates to a granulating device for biological fertilizer production. Background Art

[0002] Bio-bacterial fertilizer is developed based on the principles of soil microecology, plant nutrition, and the basic concept of modern "organic agriculture". Bio-fertilizer is a new type of fertilizer biological product in which the life activities of active (reproducible) microorganisms result in crops obtaining the required nutrients (fertilizer). It is a type of fertilizer in agricultural production (also known as the third-generation fertilizer). During the production process of bio-fertilizer raw materials, granulation treatment is required for packaging.

[0003] In the prior art (a patent application with the publication number CN214765280U and the patent name of a granulating device for biological fertilizer production), an electric motor drives a shaft rod to rotate through a rubber belt, and the spiral blades in the first cylinder and the second cylinder push the bio-fertilizer raw materials towards the forming hole plates at both ends. After the bio-fertilizer raw materials are extruded from the holes of the forming hole plates, the extruded bio-fertilizer raw materials are cut into granular by the cutter paddles at both ends of the shaft rod. At the same time, bi-directional extrusion granulation towards both ends improves the granulation processing efficiency and is worthy of popularization. In the process of implementing this technical solution, it is found that at least the following problems exist in the prior art:

At the same time, due to the insufficient viscosity of the bio-fertilizer, the bio-fertilizer is too loose when extruded and molded, resulting in low quality of the bio-fertilizer granulation molding.

[0020] 1. For the granulating device for producing biological fertilizer, first, the servo motor drives four first driven gears on the first main gear to rotate synchronously through the rotating shaft. The four first driven gears drive the mixing blades on the four stirring shafts to uniformly mix the biological fertilizer raw materials in the four preparation tanks. At the same time, the four first driven gears drive the turbulence blades to turbulently stir the binder in the storage tank through the differential gears. While preventing precipitation of the binder, the binder is quickly guided into the four conveying pipes. Then, the four metering valves and metering sensors quantitatively regulate the supplied binder. With the cooperation of the mixing blades for stirring, until the biological fertilizer raw materials in the four preparation tanks and the quantitatively added binder are fully stirred to the preset range value of the viscosity sensor, so that the viscosity of the prepared biological fertilizer raw materials meets the requirements.

[0021] 2. For the granulating device for producing biological fertilizer, then, first, the servo motor drives four second driven gears to rotate synchronously through the second main gear. The four second driven gears drive the screw sleeves on the four extrusion screws to perform linear extrusion. The four screw sleeves drive the four sliding seats to form a linear extrusion force in the four extrusion cylinders. At the same time, the four sliding seats also drive the four extrusion seats to linearly extrude the biological fertilizer raw materials reaching the four extrusion cylinders. With the four optical rods and buffer springs providing sliding support for the four sliding seats and extrusion seats, the four vibration motors vibrate and level the biological fertilizer raw materials in the four extrusion cylinders in front of the four extrusion seats, eliminating the gap bubbles between the biological fertilizer raw materials. Then, it is extruded and formed by the forming plate with "round hole shape, hexagon, square and rhombus" on the forming head, obtaining granular biological fertilizer in the shapes of circle, hexagon, square and rhombus, increasing the diversity of the forming styles of the biological fertilizer and improving its product competitiveness.

[0039] The following is a specific introduction to the present invention in conjunction with the accompanying drawings and specific embodiments:

[0040] As Figures 1 - 14 shown, a granulating device for producing biological fertilizer according to the present invention includes an underframe 1. A top frame 2 is fixedly connected to the top of the underframe 1, and a liquid storage tank 3 is fixedly connected to the top of the top frame 2. Extrusion cylinders 4 are fixedly connected to the four sides of the underframe 1, and a fixed cover 5 is arranged outside the extrusion cylinders 4. The extrusion cylinders 4 are communicated with a preparation tank 6;

[0041] Blending components used in conjunction with the preparation tank 6 are arranged on the four sides of the top frame 2, and the blending components include a servo motor 71 fixed to the bottom of the underframe 1. Supply components used in conjunction with the preparation tank 6 are arranged on the four sides of the liquid storage tank 3, and the supply components include dosing valves 83 communicated with the four sides of the preparation tank 6, which evenly mix the biological fertilizer raw materials in the four groups of preparation tanks 6, turbulently stir the binder in the liquid storage tank 3, prevent precipitation of the binder, and while meeting the on-site preparation of biological fertilizer, also facilitate the extrusion molding quality of the subsequent biological fertilizer raw materials with moderate viscosity, and avoid the biological fertilizer raw materials being too dilute and scattered when extruding due to insufficient viscosity;

[0042] Extrusion components used in conjunction with the extrusion cylinder 4 are provided around the chassis 1. The extrusion components include a second main gear 91 fixed to the output shaft of the servo motor 71. An outer side of the extrusion components is provided with a forming component used in conjunction with the extrusion cylinder 4. The forming component includes a forming head 105 threadedly connected to the outer end of the extrusion cylinder 4 and fixedly fitted with the fixed cover 5. The biological fertilizer raw materials reaching the four extrusion cylinders 4 are linearly extruded and vibrated evenly to eliminate the gap bubbles between the biological fertilizer raw materials, making them more compact. After that, granular biological fertilizers in circular, hexagonal, square, and diamond shapes are obtained, increasing the diversity of the forming styles of the biological fertilizer and improving its product competitiveness.

[0043] As Figures 4 - 10 shown, the mixing component further includes a rotating shaft 72 fixed to the output shaft of the servo motor 71. A first main gear 73 is fixedly connected to the top of the rotating shaft 72. Four first driven gears 74 are meshed around the first main gear 73. The four first driven gears 74 on the first main gear 73 are driven to rotate synchronously by the servo motor 71 through the rotating shaft 72. An outer side of the first driven gear 74 is fixedly connected to a stirring shaft 75 rotatably fitted with the top frame 2 and the fixed cover 5. Mixing blades 76 are fixedly connected around the stirring shaft 75. The mixing blades 76 on the four stirring shafts 75 are driven by the four first driven gears 74 to evenly mix the biological fertilizer raw materials in the four preparation tanks 6.

[0044] The supply component further includes a differential gear 81 meshed with the first driven gear 74. A spoiler blade 82 used in conjunction with the liquid storage tank 3 is fixedly connected to the top of the differential gear 81 through a rotating rod. A quantitative sensor 84 is embedded in the metering valve 83. An outer end of the metering valve 83 is communicated with a delivery pipe 85 communicated and fitted with the preparation tank 6. The four first driven gears 74 drive the spoiler blade 82 through the differential gear 81 to turbulently stir the adhesive in the liquid storage tank 3, preventing the adhesive from settling and quickly guiding the adhesive into the four delivery pipes 85. A viscosity sensor 86 is embedded in the mixing blade 76. Then, the supplied adhesive is quantitatively regulated through the four metering valves 83 and the quantitative sensors 84, and with the cooperation of the mixing blade 76 for stirring until the biological fertilizer raw materials in the four preparation tanks 6 and the quantitatively added adhesive are fully stirred to reach the preset range value of the viscosity sensor 86, making the viscosity of the prepared biological fertilizer raw materials meet the requirements. While meeting the on-site preparation of biological fertilizer, it is also beneficial to the extrusion forming quality of the subsequent biological fertilizer raw materials with moderate viscosity, avoiding the biological fertilizer raw materials being too dilute when extruded due to insufficient viscosity.

[0045] The blending blades 76 are distributed in an equidistant triangular state to evenly stir the raw materials of the biological fertilizer in the preparation tank 6. Moreover, mixing ports for embedding and cooperating with the viscosity sensor 86 are arrayed on the blending blades 76, which is conducive to the passage of the raw materials of the biological fertilizer through the blending blades 76 to prevent the accumulation of the raw materials of the biological fertilizer in the area of the blending blades 76. The turbulence blades 82 are distributed in an axisymmetric state and are made of a streamlined lightweight material, which reduces the weight of the turbulence blades 82 and increases the rotation speed of the turbulence blades 82 to achieve efficient turbulence and anti-precipitation effects on the binder. Moreover, the delivery pipe 85 is located below the turbulence blades 82, which is conducive to the turbulence blades 82 evenly guiding the binder in the storage tank 3 into the delivery pipe 85.

[0046] The extrusion assembly further includes that second slave gears 92 are meshed around the second main gear 91. First, the servo motor 71 drives the four groups of second slave gears 92 to rotate synchronously through the second main gear 91. Moreover, an extrusion lead screw 93 is fixedly connected to the outside of the second slave gear 92, and a lead screw sleeve 94 that is slidably matched with the chassis 1 and the extrusion cylinder 4 is threadedly connected to the extrusion lead screw 93. The four groups of second slave gears 92 drive the lead screw sleeves 94 on the four extrusion lead screws 93 to perform linear extrusion. Moreover, a sliding seat 95 that is slidably matched with the extrusion cylinder 4 is arranged on the outside of the lead screw sleeve 94. The four lead screw sleeves 94 drive the four groups of sliding seats 95 to form a linear extrusion force in the four extrusion cylinders 4.

[0047] The forming assembly further includes polished rods 101 that slide around the sliding seats 95. Moreover, an extrusion seat 102 that is slidably matched with the extrusion cylinder 4 is fixedly connected to the outside of the polished rods 101. The four groups of sliding seats 95 also drive the four groups of extrusion seats 102 to linearly extrude the raw materials of the biological fertilizer that reach the four extrusion cylinders 4. A buffer spring 103 that is fixedly matched with the sliding seats 95 and the extrusion cylinder 4 is sleeved on the polished rods 101. Moreover, a vibration motor 104 is embedded in the inner side of the extrusion seat 102. Under the sliding support and cooperation of the four polished rods 101 and the buffer spring 103 for the four groups of sliding seats 95 and the extrusion seats 102, the four vibration motors 104 vibrate and level the raw materials of the biological fertilizer in the four extrusion cylinders 4 that are extruded in front of the four extrusion seats 102 to eliminate the gap bubbles between the raw materials of the biological fertilizer. A forming plate 106 is embedded on the outside of the forming head 105. Granular biological fertilizers in circular, hexagonal, square, and diamond shapes are extruded and formed by the forming plate 106 of "circular hole shape, hexagon, square, and diamond" on the forming head 105, which increases the diversity of the forming styles of the biological fertilizer and improves its product competitiveness.

[0048] The polished rod 101 is symmetrically distributed along the transverse axis of the sliding seat 95 and the extrusion seat 102, playing a role of sliding support for the sliding seat 95 and the extrusion seat 102, improving the sliding stability of the extrusion seat 102 driven by the sliding seat 95. Moreover, the forming head 105 is designed in a frustum shape, so that the space is reduced after the biological fertilizer reaches inside the forming head 105, increasing the extrusion pressure of the biological fertilizer therein. The forming plate 106 is circumferentially provided with forming holes, and the shapes of the forming holes are respectively round hole shape, hexagon, square and rhombus, so as to obtain four kinds of granular biological fertilizers in the shapes of circle, hexagon, square and rhombus, increasing the diversity of the granulation shapes of the biological fertilizer and improving its competitiveness.

[0049] As Figures 11 - 13 shown, when extruding and forming the biological fertilizer raw material, it is necessary to cut off the extruded granular biological fertilizer. For the current cutting methods adopted, most of the lengths are different, and granular biological fertilizers with a unified specification length cannot be obtained, making it unable to meet the standard requirements. A cutting component used in combination with the forming component is provided on the fixed cover 5. The cutting component includes a cam 111 fixed outside the stirring shaft 75. First, four stirring shafts 75 drive four groups of cams 111 to rotate synchronously. A sliding head 112 is slidably connected to the cam 111, and a cutter 113 used in combination with the forming plate 106 and the tool holder 12 is fixedly connected to the bottom of the sliding head 112. The bottom of the fixed cover 5 is fixedly connected with a tool holder 12 used in combination with the forming plate 106, and a scraping groove is provided in the inner cavity of the tool holder 12 to scrape off the biological fertilizer residues adhered to the cutter 113, keeping the cutter 113 clean and improving the flatness of the cut end face of the biological fertilizer. T-shaped grooves 114 are provided on both sides of the fixed cover 5, and a T-shaped block 115 fixedly matched with the sliding head 112 is slidably connected in the T-shaped grooves 114. A return spring 116 fitted with the fixed cover 5 is fixedly connected to the bottom of the T-shaped block 115. Under the elastic buffering and elastic resetting cooperation of the four groups of sliding heads 112 by the T-shaped grooves 114, the T-shaped blocks 115 and the return spring 116, the four groups of cams 111 drive the four groups of cutters 113 to reciprocate up and down along the four groups of forming heads 105, cutting off the extruded and formed granular biological fertilizers of different shapes at a certain frequency and ensuring that the lengths of the cut granular biological fertilizers are unified and meet the standard requirements.

[0050] Working principle of a granulating device for biological fertilizer production: First, place four portions of biological fertilizer raw materials in four preparation tanks 6, and place the binder specific for biological fertilizer in the liquid storage tank 3. Then, control the servo motor 71 to start and drive the first main gear 73 and the second main gear 91 on the rotating shaft 72 to rotate synchronously. The first main gear 73 drives the stirring shafts 75 on the four first driven gears 74 to rotate accordingly. The four stirring shafts 75 drive the four mixing blades 76 to uniformly stir the biological fertilizer raw materials in the four preparation tanks 6 simultaneously. At the same time, the four first driven gears 74 also drive the turbulence blades 82 on the differential gear 81 to perform turbulence and anti-sedimentation treatment on the binder in the liquid storage tank 3. During the process of the four mixing blades 76 uniformly stirring the biological fertilizer raw materials, the viscosity is monitored in real time by four viscosity sensors 86;

[0051] When the viscosity of the biological fertilizer raw materials in the four preparation tanks 6 is insufficient, control the four metering valves 83 to open. With the cooperation of the turbulence of the turbulence blades 82, quickly divert the binder in the liquid storage tank 3 into the four delivery pipes 85. And the four metering valves 83 and the metering sensors 84 quantitatively regulate the binder reaching the four delivery pipes 85. After the four portions of binder pass through the four delivery pipes 85 and reach the four preparation tanks 6, the four mixing blades 76 fully stir the biological fertilizer raw materials and the viscosity agent in the four preparation tanks 6 to obtain biological fertilizer with appropriate viscosity;

[0052] While injecting the biological fertilizer with appropriate viscosity obtained in the four preparation tanks 6 into the front end of the inner cavity of the four extrusion cylinders 4, the second main gear 91 also drives the extrusion screws 93 on the four second driven gears 92 to rotate synchronously. The four extrusion screws 93 drive the four screw sleeves 94 to move outward synchronously. The four screw sleeves 94 drive the four sliding seats 95 and the extrusion seats 102 to slide forward in the extrusion cylinder 4 and linearly extrude the biological fertilizer reaching the four extrusion cylinders 4. At the same time, due to the reverse force generated by the biological fertilizer in the four extrusion cylinders 4 on the extrusion seats 102, it forces the four smooth rods 101 on the extrusion seats 102 to slide inward in the sliding seats 95, and the four buffer springs 103 provide elastic buffer cooperation for the linearly extruded extrusion seats 102. Control the four vibration motors 104 to start to vibrate and level the biological fertilizer in front of the four extrusion seats 102, eliminate the air bubble voids in the biological fertilizer, make it more uniform and compact. Then, under the action of the linear extrusion force of the four extrusion seats 102, force the biological fertilizer with appropriate viscosity and vibration-leveled and defoamed to be extruded into granular biological fertilizer in four shapes: circular, hexagonal, square, and rhombus through the forming plates 106 on the four forming heads 105;

[0053] While the granular biological fertilizers of four shapes are extruded through the forming plate 106, the four stirring shafts 75 drive the four groups of cams 111 to rotate synchronously with the four groups of mixing blades 76. The T-shaped grooves 114 and T-shaped blocks 115 provide sliding support and fit for the sliding heads 112, and the four return springs 116 provide elastic buffering and elastic reset for the cutters 113 on the four groups of sliding heads 112. Then, the four groups of cams 111 drive the four groups of cutters 113 to perform reciprocating lifting motion through the four groups of sliding heads 112. The four groups of cutters 113 moving in a reciprocating lifting manner cut the granular biological fertilizers of four shapes extruded at equal intervals, and the four groups of cutters 113 also insert into and pull out of the scraping grooves in the four tool holders 12 at a certain frequency to scrape and clean the biological fertilizer residues adhered to the four groups of cutters 113.

[0054] It should be noted that the specific model specifications of the servo motor 71 and the vibration motor 104 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in the field, so it will not be elaborated in detail.

[0055] The power supply circuits of the servo motor 71, the vibration motor 104, and various valves and sensors are clear to those skilled in the art and will not be described in detail here.
