Description

Technical Field

[0001] This utility model belongs to the field of bio-organic fertilizer processing technology, and more specifically, it relates to a granulator for bio-organic fertilizer. Background Technology

[0002] Organic fertilizer is a carbon-containing material primarily derived from plants and / or animals, applied to the soil to provide nutrients to plants. Processed from biological matter, animal and plant waste, and plant residues, it eliminates toxic and harmful substances and is rich in beneficial substances, including various organic acids, peptides, and abundant nutrients such as nitrogen, phosphorus, and potassium. It not only provides comprehensive nutrition for crops but also has a long-lasting effect, increasing and renewing soil organic matter, promoting microbial reproduction, and improving the soil's physical, chemical, and biological properties. It is a key nutrient source for green food production.

[0003] However, in actual use, most existing granulators use two granulating rollers for granulation. Although this achieves the granulation effect, the granulating rollers roll, which granulate in a rolling manner, can easily cause accumulation when there is a large amount of material, resulting in poor granulation. Furthermore, after the fertilizer is extruded and agglomerated into spheres by the granulator, some non-standard spheres are often mixed in. To ensure that the product meets the specifications, workers need to screen them, which wastes a lot of manpower and resources.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a granulator for bio-organic fertilizer in order to achieve a more practical value. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a granulator for bio-organic fertilizer, thereby resolving the issues raised in the background art.

[0006] The purpose and effectiveness of this utility model for a granulator of bio-organic fertilizer are achieved by the following specific technical means:

[0007] A granulator for bio-organic fertilizer includes a granulation mechanism and a screening mechanism. The granulation mechanism includes a granulation cylinder with a feed inlet at one upper end and two sets of support columns at the lower end. A mounting ring is located at the end of the granulation cylinder away from the feed inlet. An insertion groove is provided inside the mounting ring, and a granulation plate is movably mounted inside the insertion groove. Mounting bolts are provided on the granulation plate, and the granulation plate and the mounting ring are fixed together by the mounting bolts. A screening mechanism is connected to the other end of the mounting ring. The screening mechanism includes a screening box with a first discharge port at the end away from the mounting ring and a second discharge port at the lower end of the first discharge port. A first discharge baffle and a second discharge baffle are respectively provided on the outer sides of the first and second discharge ports. The outlet ends of the first and second discharge baffles are staggered. A cleaning port is located at the lower end of the second discharge port.

[0008] Furthermore, a No. 1 motor is installed at one end of the granulation cylinder near the discharge port. The output end of the No. 1 motor is connected to a drive gear. One end of the drive gear is meshed with a driven gear. The driven gear is connected to a screw conveyor bearing. The screw conveyor is located inside the granulation cylinder.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the drive gear is driven by the No. 1 motor to rotate, and the driven gear drives the auger conveyor to rotate under the meshing transmission of the gear, so as to transport the material. The conveying method of the auger conveyor has a certain buffering effect, so that the material is not directly squeezed, thereby preventing the accumulation of material when there is too much material and improving the granulation effect.

[0010] Furthermore, the granulation plate is provided with a plurality of granulation holes, and a rotating shaft is provided at the end of the granulation plate away from the auger conveyor. The rotating shaft does not contact the granulation plate, and multiple sets of blades are provided around the rotating shaft.

[0011] Furthermore, the rotating shaft is rotatably installed inside the screening box, and a first bevel gear is provided on the rotating shaft. A second bevel gear is meshed at one end of the first bevel gear, and the second bevel gear is connected to a second motor through the rotating shaft.

[0012] The beneficial effect of adopting the above-mentioned further solution is that by driving the second bevel gear to rotate through the second motor, the first bevel gear drives the blade on the rotating shaft to rotate under the meshing transmission of the gears, and spin-cuts the material extruded from the granulation hole of the granulation plate, which can quickly complete the granulation work.

[0013] Furthermore, the screening box is equipped with a No. 1 screen inside, and a No. 2 screen is provided at the lower end of the No. 1 screen. Both the No. 1 screen and the No. 2 screen are inclined, and the mesh size of the No. 2 screen is smaller than that of the No. 1 screen.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the installation and use of the No. 1 and No. 2 screens facilitate the screening of granular fertilizers, allowing non-standard granular fertilizers such as oversized particles, broken particles, and under-formed particles to be screened out. This enables the fertilizer to be screened directly after granulation, reducing the production cycle of fertilizers in the production and processing process, improving fertilizer production efficiency, and enhancing the practicality of the granulator.

[0015] Furthermore, the No. 1 and No. 2 screens are provided with screen frames at one end near the granulation mechanism, and a fixing block is connected to the other end of the screen frame. A return spring is provided inside the fixing block, and a telescopic block is connected to the other end of the return spring.

[0016] Furthermore, the telescopic block is movably embedded in the fixed block, and a connecting rod is rotatably connected to the other end of the telescopic block. A cam is rotatably connected to the other end of the connecting rod, and a rotating shaft is connected to the other end of the cam. Mounting brackets are connected to both ends of the rotating shaft, and a No. 3 motor is connected to one end of the rotating shaft.

[0017] The beneficial effect of adopting the above-mentioned further solution is that by driving the rotating shaft with the No. 3 motor to rotate the cam, the connecting rod can drive the telescopic block to move. Under the action of the return spring, the fixed block can drive the screen frame to vibrate, thereby improving the conveying of materials and preventing materials from adhering to the No. 1 or No. 2 screen.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This granulator for bio-organic fertilizer uses a primary motor to drive a drive gear, which in turn drives a driven gear to rotate an auger conveyor to transport the material. The auger conveyor provides a buffering effect, preventing direct compression of the material and thus avoiding accumulation and improving granulation efficiency. A secondary motor drives a secondary bevel gear, which in turn drives a primary bevel gear to rotate blades on a rotating shaft, cutting the material extruded from the granulation holes on the granulation plate. This allows for rapid granulation. The use of primary and secondary screens facilitates the screening of granular fertilizer. This granulation method allows for the separation of non-standard granular fertilizer particles, such as oversized, broken, and under-formed particles, enabling direct screening after granulation. This reduces the production cycle, improves efficiency, and enhances the practicality of the granulator. A third motor drives a rotating shaft, which in turn rotates a cam. This, in turn, causes a connecting rod to move a telescopic block. A return spring then causes a fixed block to vibrate the screen frame, improving material transport and preventing material adhesion to the first or second screen. This invention features a simple and reasonable structure, novel design, and easy assembly, making it highly practical. Attached Figure Description

[0031] A primary motor 104 is installed near the discharge port of the granulation cylinder. The output of the primary motor 104 is connected to a drive gear 105, one end of which meshes with a driven gear 106. The driven gear 106 is bearing-connected to an auger conveyor 107, which is located inside the granulation cylinder body 101. A plurality of granulation holes 112 are arranged around the granulation plate 110. A rotating shaft 113 is located at the end of the granulation plate 110 away from the auger conveyor. The rotating shaft 113 does not contact the granulation plate 110 and is surrounded by multiple sets of blades 114. The rotating shaft 113 is rotatably mounted inside the screening box 201.

The material extruded from the granulation hole 112 is rotary cut, which can quickly complete the granulation process. The granulated fertilizer falls onto the first screen 207 or the second screen 208 to screen out non-standard granules such as oversized particles, broken particles, and under-formed particles. This reduces the production cycle of fertilizer production and improves the production efficiency of fertilizer, enhancing the practicality of the granulator. At the same time, the rotating shaft 215 driven by the third motor 216 drives the cam 214 to rotate, which enables the connecting rod 213 to drive the telescopic block 212 to move. Under the action of the return spring 211, the fixed block 210 drives the screen frame 209 to vibrate, thereby improving the material conveying and preventing the material from adhering to the first screen 207 or the second screen 208.
