Description

Technical Field

[0001] The present invention relates specifically to the technical field of biofertilizer manufacturing, in particular to a microbial fertilizer manufacturing device. Background Art

[0002] In the process of green development of modern agriculture, microbial fertilizers have become a key agricultural input for promotion due to their advantages in improving soil structure, increasing fertilizer efficiency, and reducing environmental pollution. Microbial fertilizers require a precise proportion of organic materials, microbial agents, and inorganic nutrients, which are thoroughly mixed before fermentation. Therefore, the mixing quality of the mixture directly affects product quality and production efficiency. When mixing the raw materials of traditional microbial fertilizers, it is necessary to mix a variety of different raw materials (straw, livestock manure). However, organic materials may clump together, resulting in a significant difference in particle size from the micron-level microbial agent, making it difficult to fully disperse. In actual mixing, even if the mixing time is extended, local enrichment or uneven distribution of the agent will still occur, resulting in large differences in the number of effective live bacteria in different parts of the fertilizer, seriously affecting the stability and consistency of the fertilizer effect. Traditional mixing devices can remove large amounts of impurities (such as metal debris, plastic particles, and stones) from raw materials. These impurities, when mixed into fertilizer, not only affect fertilizer quality but can also damage subsequent packaging and application equipment, posing a potential risk of soil contamination. At present, traditional fertilizer equipment stacks and mixes various microbial raw materials directly on site when manufacturing fertilizers. In this way, external impurities may be mixed into the raw materials during the stacking process, and such impurities will affect the quality of the fertilizer after mixing. The existing mixing equipment cannot effectively deal with the differences between the raw materials. In this way, when fertilizers are manufactured, the internal microbial agents will be uneven. When the unevenness rate in a certain area reaches more than 30%, it will seriously affect the quality of the fertilizer. Summary of the Invention

[0003] The object of the present invention is to provide a microbial fertilizer manufacturing device, in which a variety of raw materials are transmitted through the material box on the top of the support frame to the inside of the crushing box, and the crushing rollers inside the crushing box effectively realize the crushing of different organic matter, thereby reducing the gap between the organic materials. At the same time, the impurities present in the materials can also be crushed, thereby reducing the volume of the impurities and avoiding the influence of larger impurities on the mixing effect of the various organic materials. When the organic materials are added, the driving component is coordinated with the first transmission component and the second transmission component to effectively realize the simultaneous crushing and mixing of the materials. In this way, the crushed materials are effectively mixed with other organic materials during the circulation mixing process, thereby effectively ensuring the quality of the microbial fertilizer; so as to solve the problems of the above-mentioned background technology.

The first driven bevel gear 46 is coaxially provided with a second driven bevel gear 44 through the transmission shaft 42. The second driven bevel gear 44 is meshed with the first bevel gear 70. The first bevel gear 70 is fixedly mounted on one end of the transmission rod 71.

The top of the rotating shaft on which the driven bevel gears 83 are mounted is fixedly provided with a corresponding rotating head 105, so that the rotating head 105 drives the slide bar 104 to rotate, and the wedge block 101 movably mounted at the end of the slide bar 104 engages and slides with the slide groove opened on the guide rail 102, so that the slide bar 104 drives the wedge block 101 to rotate along the guide rail 102. When the wedge block 101 is in motion, the organic material is mixed. A protrusion 106 is integrally provided on the guide rail 102. In this way, the wedge block 101 cooperates with the protrusion 106 to effectively adjust the wedge block 101 up and down, thereby effectively collecting the edge materials to the middle position. Since the two driven bevel gears 83 rotate in opposite directions, the two wedge blocks 101 are always consumed in alternating mixing, thereby effectively ensuring the efficiency of fertilizer mixing production. In this embodiment, two sets of symmetrical rollers 32 are mounted on the side walls of the crushing box 30. The rollers 32 are movably mounted on a fixing frame 33, which extends to the outside of the support frame 1. The fixing frame 33 is fixedly mounted on the side away from the crushing box 30 by a C-shaped frame 34. The C-shaped frame 34 is welded to the support frame 1. By adopting the above technical solution, after the fertilizer inside the manufacturing box 5 is manufactured, the two electric push cylinders 90 are used to synchronously retract the push rods to realize that the first movable plate 91 drives the second movable plate 93 to move toward the inside of the support frame 1, and the end of the second movable plate 93 is movably installed with the side wall of the crushing box 30 to achieve the pushing effect of the crushing box 30 and the manufacturing box 5. When the crushing box 30 is subjected to force, the rollers 32 on both sides of the crushing box 30 roll along the corresponding fixed frames 33 to move the crushing box 30 out of the support frame 1, and then by opening the movable door 6 on the side wall of the manufacturing box 5, the manufactured fertilizer can be effectively discharged; The working principle of the present invention is as follows: when in use, a variety of organic raw materials and microbial carriers are added to the crushing box 30 through the material box 2, and the organic raw materials are effectively crushed by the multiple crushing rollers 31 inside the crushing box 30. The multiple crushing rollers 31 rotate synchronously through multiple spur gears 36. After the crushing, the differences between the organic materials are small, which effectively ensures that a variety of different organic materials can be fully mixed and attached to the carrier during the production of fertilizers. During crushing, the motor 40 drives the connecting rod 41 to rotate, and the driving pulley 43 installed at the end of the connecting rod 41 away from the motor 40 is connected to the driven pulley 35 at the end of one of the crushing rollers 31 through the belt 37, so as to achieve the effect of synchronous driving of multiple crushing rollers 31, thereby effectively ensuring the quality of crushing. After crushing, the material falls onto the carrier plate 100 inside the manufacturing box 5 below, and is circulated and mixed through the mixing assembly 10; During the crushing process, when the connecting rod 41 drives the driving pulley 43 to rotate, the driving bevel gear 45 on the connecting rod 41 rotates synchronously, and the driving bevel gear 45 meshes with the first driven bevel gear 46. The first driven bevel gear 46 is coaxially provided with a second driven bevel gear 44 through the transmission shaft 42. The second driven bevel gear 44 meshes with the first bevel gear 70. The first bevel gear 70 is fixedly mounted on one end of the transmission rod 71. The second bevel gear 72 fixedly mounted on the other end of the transmission rod 71 meshes with the lower bevel gear 80, thereby transmitting the drive of the motor 40 to the second transmission assembly 8. The upper bevel gear 82 coaxially arranged with the lower bevel gear 80 meshes with the two driven bevel gears 83, so that the two driven bevel gears 83 rotate in opposite directions. The top of the rotating shaft on which the driven bevel gears 83 are mounted is fixedly provided with a corresponding rotating head 105, so that the rotating head 105 drives the slide bar 104 to rotate. The wedge block 101 movably mounted at the end of the slide bar 104 slides in engagement with the slide groove provided on the guide rail 102. In this way, when the slide bar 104 drives the wedge block 101 to rotate along the guide rail 102, the wedge block 101 is rotated by the wedge. The wedge block 101 realizes mixing of organic materials. A protrusion 106 is also integrally provided on the guide rail 102. In this way, the wedge block 101 cooperates with the protrusion 106 to effectively achieve the effect of adjusting the wedge block 101 up and down, thereby effectively collecting the materials on the edge to the middle position. Since the two driven bevel gears 83 rotate in opposite directions, the two wedge blocks 101 always alternately mix the materials, thereby effectively ensuring the efficiency of fertilizer mixing production. After the fertilizer inside the manufacturing box 5 is manufactured, the two electric push cylinders 90 synchronously retract the push rods to realize that the first movable plate 91 drives the second movable plate 93 to move toward the inside of the support frame 1, and the end of the second movable plate 93 is movably installed with the side wall of the crushing box 30 to achieve the pushing effect on the crushing box 30 and the manufacturing box 5. When the crushing box 30 is subjected to force, the rollers 32 on both sides of the crushing box 30 roll along the corresponding fixed frames 33 to move the crushing box 30 out of the support frame 1, and then by opening the movable door 6 on the side wall of the manufacturing box 5, the manufactured fertilizer can be effectively discharged.
