Description

Technical Field

[0001] This utility model relates to the field of fertilizer granulation technology, and in particular to a high-efficiency granulation and molding equipment for oyster shell fertilizer. Background Technology

[0002] Oyster shells are the outer shells of oysters, belonging to the bivalve mollusks. Oyster shells are composed of calcite and calcium carbonate, a natural mineral rich in calcium carbonate. They possess water and air retention capabilities, and when combined with soil humus, their granular structure enhances their fertilizer retention capacity. Therefore, they are widely used in agriculture, aquaculture, and environmental protection.

[0003] Prior art application number 202120953245.1 discloses a granulation device for oyster shell soil conditioner, including a box body, a crushing mechanism, an extrusion mechanism, a shearing mechanism, and a discharge mechanism. A filter screen is clamped to the upper part of the inner wall of the box body, and a shearing screen is clamped to the inner wall of the box body below the filter screen. A box cover is clamped to the top of the box body, and a crushing mechanism is installed on the box cover, located above the filter screen. The crushing mechanism is connected to the extrusion mechanism via a coupling, and a shearing mechanism is installed at the bottom end of the extrusion mechanism. The extrusion mechanism cooperates with the shearing screen, and a discharge mechanism is provided in the middle of the bottom end of the box body. This utility model can conveniently shear soil conditioner extruded into thin strips into granules, avoiding the need to transport it to a shearing device for shearing, and saving transportation time, thereby saving production time.

[0004] However, the above technical solution has some problems: the rotation axis of the shearing mechanism is perpendicular to the shearing mesh, and there are multiple discharge ports on the shearing mesh. When the rotation speed of the shearing mechanism remains constant, the farther away from the rotation axis of the shearing mechanism, the more discharge ports the shearing blade passes through. That is, the farther away from the rotation axis of the shearing mechanism, the shorter the extrusion time of the discharge port. The size of the formed particles sheared from the discharge port is inversely proportional to the distance between the rotation axes of the shearing mechanism, which in turn affects the later use of fertilizer and the fertilization effect. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a high-efficiency granulation and forming equipment for oyster shell fertilizer. The distance between the rotation axis of the shearing mechanism and any extrusion port is the same, and the distance between any part of any shearing blade and the rotation axis of the shearing mechanism is also the same. This ensures that the material is cut at the discharge port at the same time, thereby ensuring the uniformity of the formed granules and avoiding inconsistent particle sizes. It is a simple, efficient, safe, reliable, and easy-to-operate equipment for oyster shell fertilizer.

[0006] This utility model is achieved through the following technical solution: It provides a high-efficiency granulation and molding equipment for oyster shell fertilizer, including a storage box with several extrusion ports. Each extrusion port is equipped with a shearing mechanism. The distance between the rotation axis of any extrusion port and the shearing mechanism is the same. The shearing mechanism includes several shearing blades evenly arranged around the rotation axis of the shearing mechanism. The distance between any part of any shearing blade and the rotation axis of the shearing mechanism is the same, and the movement trajectory of the shearing blade intersects the axis of the extrusion port. The shearing mechanism drives the shearing blades to rotate. Because the distance between the rotation axis of the shearing mechanism and any extrusion port is the same, and the distance between any part of any shearing blade and the rotation axis of the shearing mechanism is the same, the material is cut at the same time at the discharge port, thus ensuring the uniformity of the granules and avoiding inconsistent particle sizes.

[0007] As an optimization, a rotating shaft extending toward the extrusion port is provided inside the storage box, and an auger is coaxially fixed on the rotating shaft. A drive mechanism A is provided on the storage box to drive the rotating shaft to rotate. The drive mechanism A drives the auger to rotate through the rotating shaft, and the material is extruded while being transported by the auger. The discharge speed of the extrusion port is controlled by controlling the rotation speed of the auger, thereby controlling the speed of pellet forming.

[0008] As an optimization, the shearing mechanism includes a rotating drum mounted on the storage bin, with the axis of the rotating drum being the same as the rotation axis of the shearing mechanism; the rotating drum has several through holes evenly arranged along its circumference, and the shearing blade is located inside the through holes; the shaped particles cut by the shearing blade directly enter the rotating drum through the through holes, making it easy to collect the shaped particles.

[0009] As an optimization, the drum is equipped with an upward-opening receiving groove, which is located directly below the shearing blade. The receiving groove collects the formed particles, preventing the shearing blade from cutting the particles again and damaging the formed particles.

[0010] As an optimization, the receiving trough is equipped with an inclined guide plate, and the bottom of the guide plate extends outside the rotating drum; the formed particles in the receiving trough are discharged through the guide plate to prevent the formed particles from accumulating in the receiving trough, thereby avoiding affecting subsequent particle production.

[0011] As an optimization, a stirring mechanism is coaxially fixed on the rotating shaft and located above the auger; the stirring mechanism stirs the oyster shell powder and other ingredients, so that the oyster shell powder and other ingredients are evenly mixed.

[0012] As an optimization, the storage bin is divided into a mixing chamber and an extrusion chamber by a partition. The mixing mechanism is located in the mixing chamber, and the auger is located in the extrusion chamber. The partition is provided with a guide port that connects the mixing chamber and the extrusion chamber, and the guide port is equipped with a valve. The partition separates the mixing operation and the extrusion operation, avoiding mutual interference between the two operations.

[0013] As an optimization, a material collection hopper A is provided at the bottom of the mixing chamber, and the material guide port is located at the bottom of the material collection hopper A; the material in the mixing chamber is collected through the material collection hopper A to avoid a large amount of material remaining in the mixing chamber.

[0014] As an optimization, a material collection hopper B is provided at the bottom of the extrusion chamber, and the extrusion port is located at the bottom of the material collection hopper B; the material in the extrusion chamber is collected by the material collection hopper B, avoiding a large amount of material remaining in the extrusion chamber.

[0015] The beneficial effects of this utility model are as follows: the shearing mechanism drives the shearing blade to rotate. Since the distance between the rotation axis of the shearing mechanism and any extrusion port is the same, and the distance between any part of any shearing blade and the rotation axis of the shearing mechanism is the same, the material discharge time at the discharge port is the same when the shearing blade cuts the material at the discharge port, thereby ensuring the uniformity of the formed particles and avoiding uneven particle size; the driving mechanism A drives the auger to rotate through the rotating shaft. The material is transmitted through the auger while being squeezed, thereby controlling the discharge speed of the extrusion port by controlling the rotation speed of the auger, and thus controlling the particle forming speed.

[0023] The storage bin 1 has a feed inlet 101; the extrusion port 102 is located at the bottom of the storage bin 1, and a protective cover 12 is fixed on the storage bin 1.

[0024] Oyster shell powder and other ingredients are fed into the storage bin 1. The materials are discharged through the extrusion port 102. The shearing mechanism 2 is started. The shearing mechanism 2 drives the shearing blade 201 to rotate and pass through the extrusion port 102 in sequence. When the shearing blade 201 passes through the extrusion port 102, it cuts the material discharged from the extrusion port 102 to complete the fertilizer granulation.

[0026] Oyster shell powder and other ingredients are fed into the storage bin 1. The drive mechanism A6 is started. The drive mechanism A6 drives the auger 4 to rotate through the rotating shaft 3. Under the action of the auger 4, the material is transported along the conveying direction of the auger 4 and gradually gathers at the extrusion port 102. As the material gathers, the pressure at the extrusion port 102 gradually increases, and the material is accelerated to be extruded from the extrusion port 102.

[0027] like Figure 1 , Figure 2 and Figure 3The shearing mechanism 2 shown includes a rotating drum 202 mounted on the storage bin 1, and the axis of the rotating drum 202 is the same as the rotation axis 3 of the shearing mechanism 2. The rotating drum 202 has several through holes evenly arranged along the circumference of the rotating drum 202, and the shearing blade 201 is located in the through holes. A driven wheel 13 is coaxially fixed on the rotating drum 202, and the driven wheel 13 is drivenly connected to the driving wheel 14. The driving wheel 14 is connected to the drive mechanism B15. The drive mechanism B15 is fixed on the storage bin 1, and the driving wheel 14 is rotatably mounted on the storage bin 1. The drive mechanism B15 is prior art and can be an electric motor.

[0028] The material is extruded from the extrusion port 102. The shearing mechanism 2 is started, the rotating drum 202 rotates and drives the shearing blade 201 to rotate. The shearing blade 201 passes through the extrusion port 102 in sequence and cuts the material extruded from the extrusion port 102 to complete the fertilizer granulation. At the same time, the granulated particles pass through the through hole and enter the rotating drum 202.

[0029] like Figure 1 , Figure 2 and Figure 3 The rotating drum 202 shown has an upward-opening receiving groove 7, which is located directly below the shearing blade 201.

[0030] The formed particles pass through the through hole into the rotating drum 202 and fall into the receiving trough 7.

[0031] like Figure 1 , Figure 2 and Figure 3 The material receiving trough 7 shown is provided with an inclined guide plate 8, and the bottom of the guide plate 8 extends outside the rotating drum 202.

[0032] The formed particles in the receiving trough 7 slide along the guide plate 8 to the outside of the rotating drum 202.

[0035] like Figure 1 and Figure 3 The storage bin 1 shown is divided into a mixing chamber and a pressing chamber by a partition 103. The mixing mechanism 5 is located in the mixing chamber, and the auger 4 is located in the pressing chamber. A guide port connecting the mixing chamber and the pressing chamber is provided on the partition 103, and a valve 11 is provided at the guide port. The feed port 101 is connected to the mixing chamber.

[0036] Oyster shell powder and other ingredients are fed into storage bin 1. The materials enter the mixing chamber. Drive mechanism A6 is started. Drive mechanism A6 drives mixing mechanism 5 to rotate through shaft 3. The materials are mixed evenly under the action of mixing mechanism 5. Valve 11 is opened. The mixed materials enter the extrusion chamber. Valve 11 is closed. Drive mechanism A6 drives auger 4 to rotate through shaft 3. The materials are transported along the conveying direction of auger 4 under the action of auger 4 and gradually gather at extrusion port 102. As the materials gather, the pressure at extrusion port 102 gradually increases, and the materials are accelerated to be extruded from extrusion port 102.

[0040] The material at the bottom of the extrusion chamber gathers at the bottom of the collection hopper B10.

[0041] In actual production, oyster shell powder and other ingredients are fed into storage bin 1. The materials enter the mixing chamber, and drive mechanism A6 is activated. Drive mechanism A6 drives mixing mechanism 5 to rotate via rotating shaft 3. The materials are uniformly mixed under the action of mixing mechanism 5. The materials at the bottom of the mixing chamber gather at the bottom of collection hopper A9. Valve 11 is opened, and the mixed materials enter the extrusion chamber. Valve 11 is then closed. Drive mechanism A6 drives auger 4 to rotate via rotating shaft 3. The materials are transported along the conveying direction of auger 4 under the action of auger 4 and gradually gather at extrusion port 102. As the materials gather, the pressure at extrusion port 102 gradually increases. The materials at the bottom of the extrusion chamber gather at the bottom of collection hopper B10, and the materials are accelerated out of extrusion port 102.

[0042] Material is extruded from the extrusion port 102. The shearing mechanism 2 is started, the rotating drum 202 rotates and drives the shearing blade 201 to rotate. The shearing blade 201 passes through the extrusion port 102 in sequence and cuts the material extruded from the extrusion port 102 to complete fertilizer granulation. At the same time, the granulated particles pass through the through hole into the rotating drum 202 and fall into the receiving groove 7. The granulated particles in the receiving groove 7 slide along the guide plate 8 to the outside of the rotating drum 202.
