Description

Technical Field

[0001] The present invention relates to the technical field of organic fertilizer fermentation equipment, and specifically relates to an agricultural waste organic fertilizer fermentation equipment. Background Art

[0002] Agricultural waste is the general term for the waste discharged from agricultural production, agricultural product processing, livestock and poultry breeding, and rural residents' lives. Bio-organic fertilizer refers to a type of fertilizer that combines specific functional microorganisms and mainly organic materials derived from animal and plant residues and has been harmlessly treated and decomposed, and has the effects of both microbial fertilizers and organic fertilizers. In the process of processing agricultural waste into organic fertilizer, it is necessary to stir and mix the agricultural waste and ferment it, and an agricultural waste organic fertilizer fermentation equipment will be used.

[0003] When the existing agricultural waste fermentation equipment crushes materials, when the amount of materials is large or wet, the materials are likely to accumulate at the feed inlet connecting the crushing chamber and the stirring chamber. Therefore, a continuously rotating rotating paddle is usually installed at the feed inlet, and the rotating paddle disperses the accumulated materials to facilitate the flow of materials. However, the position of the rotating paddle is usually fixed, and there are likely to be some dead corners for dispersion, resulting in poor material flow efficiency and affecting the working efficiency of organic fertilizer fermentation. In addition, a power component for driving the rotating paddle needs to be additionally provided, increasing the energy consumption of the equipment. Therefore, we propose an agricultural waste organic fertilizer fermentation equipment. Summary of the Invention

[0008] Preferably, one side of the moving plate close to the rack is connected to a guide rod. Both the rack and the guide rod are slidably sleeved with the inner wall of the crushing feed hopper. The two sides of the rack are respectively meshed with a first sector gear and a second sector gear. The upper part of the first sector gear is fixedly connected to a second gear through a rotating shaft.

[0009] Preferably, one side of the second gear is meshed with a first gear. One side of the first gear is fixedly connected to a driven tooth disc through a rotating shaft. And the rotating shaft on one side of the driven tooth disc is connected to the outer wall of the crushing feed hopper through a bearing.

[0010] Preferably, a transmission shaft is fixedly connected to the lower part of the second sector gear. The transmission shaft is connected to the stirring cylinder through a bearing. One end of the transmission shaft away from the second sector gear is fixedly connected to a third gear. One side of the third gear is meshed with a fourth gear. The fourth gear is fixedly sleeved with a stirring rod.

[0011] Preferably, a fermentation cylinder is connected to the lower part of the blanking cavity. A heat preservation layer is fixedly sleeved on the outer side of the fermentation cylinder. A frame is installed on the outer side of the stirring cylinder through bolts. A sealing door is installed on one side of the fermentation cylinder through bolts. A blanking mechanism is arranged on the inner side of the stirring cylinder close to the blanking cavity. And one side of the blanking mechanism is located outside the stirring cylinder.

[0012] Preferably, the blanking mechanism includes a valve plate, a first side rod, a swing rod, and a hydraulic push rod. A valve plate is arranged on the inner wall of the stirring cylinder close to the blanking cavity. The two ends of the valve plate are respectively connected to a first side rod and a second side rod.

[0013] Preferably, the first side rod is installed on the inner wall of the stirring cylinder through a bearing. One end of the first side rod close to the outside of the stirring cylinder is fixedly connected to a swing rod. A support plate is fixed on the outer wall of the stirring cylinder.

[0014] Preferably, a hydraulic push rod is connected between the swing rod and the support plate through a movable shaft. The first side rod and the second side rod are both movably sleeved with the end part of the stirring rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: For this agricultural waste organic fertilizer fermentation equipment, by arranging a rotatable rod and stirring paddles that can reciprocate and rotate at the bottom feed inlet of the feed crushing hopper, the materials accumulated at the feed inlet can be turned over and dispersed, preventing accumulation. Moreover, the telescopic mechanism that provides power to the rotatable rod and stirring paddles operates simultaneously with the stirring motor and the crushing motor. There is no need to set up additional driving components on the telescopic mechanism. The stirring motor and the crushing motor can promote the material flow efficiency while stirring and crushing the materials, reducing energy consumption and improving the equipment operation efficiency. Also, through the separated setting of the fermentation cylinder and the stirring cylinder, it is beneficial to carry out fermentation and stirring work simultaneously, reducing the risks of microbial contamination and cross-contamination, and improving the working quality and practicability of the agricultural waste organic fertilizer fermentation equipment.

[0016] 1. For this agricultural waste organic fertilizer fermentation equipment, the crushed materials are prone to accumulate at the bottom of the crushing feed hopper. By meshing one side of the second crushing tooth disc with the driven tooth disc, the second crushing tooth disc drives the driven tooth disc to rotate, the driven tooth disc drives the first gear to rotate, the first gear then drives the second gear to rotate, and the second gear drives the first sector gear to rotate through the rotating shaft. At the same time, the stirring motor drives the stirring rod to rotate, the stirring rod then drives the fourth gear to rotate, then the fourth gear drives the third gear to rotate, and finally the third gear makes the transmission shaft drive the second sector gear to rotate. The first sector gear and the second sector gear rotate in the same direction simultaneously. By intermittently meshing the first sector gear and the second sector gear with the rack, the rack can be driven to stretch back and forth, causing the rack to slide and pull the moving plate to move within the inner cavity of the fixed cylinder. At the same time, the guide rod slides on the inner wall of the feed crushing hopper. The moving plate squeezes or pulls the circular plate and the rotatable rod. After the circular plate is squeezed and pulled, the sliders at both ends of the circular plate slide along the spiral groove. Since the spiral groove is annularly distributed on the inner wall of the fixed cylinder, the sliders drive the circular plate to rotate rapidly, the circular plate drives the rotatable rod to rotate, and then the rotatable rod drives the stirring paddles to rotate. Through the stretching of the rack, the rotatable rod reciprocates and drives the stirring paddles to rotate, which can disperse the materials accumulated at the bottom of the crushing feed hopper, and the stirring paddles can also turn over and impact the crushed materials to play an auxiliary crushing role, making the material particles further smaller, while promoting the material flow and facilitating the materials to quickly enter the stirring cylinder, avoiding the materials staying under the crushing roller for too long, thereby improving the working efficiency of the organic fertilizer fermentation equipment;

[0017] 2. For this agricultural waste organic fertilizer fermentation equipment, since the driving force of the telescopic mechanism is provided by the crushing motor and the stirring motor, there is no need to install other power components. It can promote the material flow while crushing and stirring the materials, reducing energy consumption and dispersing the working burden of a single motor, improving the practicability of the agricultural waste organic fertilizer fermentation equipment;

[0018] 3. The agricultural waste organic fertilizer fermentation equipment can, after the stirring motor drives the stirring rod to rotate and stir and mix the materials, start the hydraulic push rod, so that the hydraulic push rod extends to push one end of the swing rod to rotate around one end of the first side rod. Since the swing rod and the first side rod are fixedly connected, the swing rod drives the first side rod to rotate, and then the first side rod drives the valve plate to rotate. At the same time, one end of the valve plate drives the second side rod to rotate outside the stirring rod, and the valve plate can be opened, enabling the stirred and mixed materials to slide into the fermentation cylinder. The materials can fully ferment in the fermentation cylinder. After fermentation is completed, the sealed door is opened to take out the materials fermented into organic fertilizer. By setting the stirring cylinder and the fermentation cylinder separately, it is beneficial to carry out fermentation and stirring work simultaneously, and reduces the risks of microbial contamination and cross-contamination, improving the working quality of the agricultural waste organic fertilizer fermentation equipment.

Detailed implementation mode

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1 - 8 , the present invention provides a technical solution: an agricultural waste organic fertilizer fermentation device, including a mixing drum 1 and a mixing rod 12. A crushing feed hopper 2 is connected above the mixing drum 1, a blanking chamber 16 is connected below the mixing drum 1. The mixing rod 12 is installed in the inner cavity of the mixing drum 1 through a bearing, and a mixing motor 10 connected to the mixing rod 12 through a coupling is installed outside the mixing drum 1.

[0034] Please refer to Figure 2 , Figure 3 and Figures 5 - 12, a fixed cylinder 23 is welded to the bottom end of the inner cavity of the crushing feed hopper 2. A moving plate 24 is arranged inside the fixed cylinder 23. One side of the moving plate 24 is mounted with a rotating rod 26 through a bearing. A circular plate 25 is fixedly sleeved on the outer side of the rotating rod 26. Two sides of the circular plate 25 are fixedly connected with sliding blocks 29. A spiral groove 30 is formed on the inner wall of the fixed cylinder 23, and the spiral groove 30 is slidably connected with the sliding blocks 29. One side of the moving plate 24 away from the rotating rod 26 is connected with a telescopic mechanism 7 and a guide rod 28. Stirring paddles 27 are fixedly arranged at equal intervals on the outer side of the rotating rod 26. A first crushing roller 17 and a second crushing roller 18 are mounted through bearings in the inner cavity of the crushing feed hopper 2 above the rotating rod 26. One ends of the first crushing roller 17 and the second crushing roller 18, which are the same, are respectively fixedly connected with a second crushing tooth disc 21 and a first crushing tooth disc 19. A crushing motor 20 connected to the first crushing roller 17 through a coupling is mounted on the support of the crushing feed hopper 2. One side of the second crushing tooth disc 21 is connected with the telescopic mechanism 7. The telescopic mechanism 7 includes a driven tooth disc 701, a first gear 702, a second gear 703, a first sector gear 704 and a rack 705. One side of the moving plate 24 is fixedly connected with the rack 705. One side of the moving plate 24 close to the rack 705 is connected with the guide rod 28. Both the rack 705 and the guide rod 28 are slidably sleeved with the inner wall of the crushing feed hopper 2. The two sides of the rack 705 are respectively meshed with a first sector gear 704 and a second sector gear 22. A second gear 703 is fixedly connected above the first sector gear 704 through a rotating shaft. One side of the second gear 703 is meshed with the first gear 702. One side of the first gear 702 is fixedly connected with the driven tooth disc 701 through a rotating shaft, and the rotating shaft on one side of the driven tooth disc 701 is connected with the outer wall of the crushing feed hopper 2 through a bearing. A transmission shaft 9 is fixedly connected below the second sector gear 22. The transmission shaft 9 is connected with the mixing cylinder 1 through a bearing. One end of the transmission shaft 9 away from the second sector gear 22 is fixedly connected with a third gear 14. One side of the third gear 14 is meshed with a fourth gear 15. The fourth gear 15 is fixedly sleeved with the stirring rod 12. The spiral groove 30 is distributed in a bidirectional structure on the inner wall of the fixed cylinder 23.

[0035] During specific implementation, after the staff pour agricultural waste into the crushing feed hopper 2, the crushing motor 20 drives the second crushing tooth disc 21 to rotate. The second crushing tooth disc 21 is meshed and connected with the first crushing tooth disc 19, so that the second crushing tooth disc 21 drives the first crushing tooth disc 19 to rotate relatively. The second crushing tooth disc 21 and the first crushing tooth disc 19 respectively drive the first crushing roller 17 and the second crushing roller 18 to rotate. The first crushing roller 17 and the second crushing roller 18 roll and crush the agricultural waste materials, crushing large particles into small granular shapes. The crushed materials are likely to accumulate at the bottom of the crushing feed hopper 2. At this time, one side of the second crushing tooth disc 21 is meshed with the driven tooth disc 701, and the second crushing tooth disc 21 drives the driven tooth disc 701 to rotate. The driven tooth disc 701 drives the first gear 702 to rotate, and the first gear 702 then drives the second gear 703 to rotate. The second gear 703 drives the first sector gear 704 to rotate through a rotating shaft;

[0036] Meanwhile, the stirring motor 10 drives the stirring rod 12 to rotate. The stirring rod 12 then drives the fourth gear 15 to rotate. Subsequently, the fourth gear 15 drives the third gear 14 to rotate. Finally, the third gear 14 makes the transmission shaft 9 drive the second sector gear 22 to rotate. The first sector gear 704 and the second sector gear 22 rotate in the same direction simultaneously. By intermittently meshing and connecting the first sector gear 704 and the second sector gear 22 with the rack 705, the rack 705 can be driven to stretch back and forth, causing the rack 705 to slide and pull the moving plate 24 to move within the inner cavity of the fixed cylinder 23. At the same time, the guide rod 28 slides on the inner wall of the crushing feed hopper 2. The moving plate 24 squeezes or pulls the circular plate 25 and the rotating rod 26. After the circular plate 25 is squeezed and pulled, the sliders 29 at both ends of the circular plate 25 slide along the spiral groove 30. Since the spiral groove 30 is annularly distributed on the inner wall of the fixed cylinder 23, the sliders 29 drive the circular plate 25 to rotate rapidly. The circular plate 25 drives the rotating rod 26 to rotate. Subsequently, the rotating rod 26 drives the stirring paddle 27 to rotate. Through the stretching of the rack 705, the rotating rod 26 reciprocates and drives the stirring paddle 27 to rotate, which can disperse the materials accumulated at the bottom of the crushing feed hopper 2. Moreover, the stirring paddle 27 can flip and impact the crushed materials to a certain extent, playing a role in assisting crushing, making the material particles further smaller, and at the same time promoting the flow of materials, facilitating the rapid entry of materials into the stirring cylinder 1, and preventing the materials from staying under the crushing rollers for too long, thereby improving the working efficiency of the organic fertilizer fermentation equipment;

[0037] Since the driving force of the telescopic mechanism 7 is provided by the crushing motor 20 and the stirring motor 10, there is no need to install other power components. It can promote the flow of materials while crushing and stirring the materials, reduce energy consumption, disperse the working burden of a single motor, and improve the practicability of the agricultural waste organic fertilizer fermentation equipment.

[0038] Please refer to Figures 1 - 6, a fermentation cylinder 5 is connected below the blanking chamber 16. A heat preservation layer 3 is fixedly sleeved outside the fermentation cylinder 5. A frame 4 is installed on the outside of the stirring cylinder 1 through bolts. A sealing door 6 is installed on one side of the fermentation cylinder 5 through bolts. A blanking mechanism 8 is arranged inside the stirring cylinder 1 near the blanking chamber 16, and one side of the blanking mechanism 8 is located outside the stirring cylinder 1. The blanking mechanism 8 includes a valve plate 801, a first side rod 802, a swing rod 803 and a hydraulic push rod 804. A valve plate 801 is arranged on the inner wall of the stirring cylinder 1 near the blanking chamber 16. Both ends of the valve plate 801 are respectively connected with a first side rod 802 and a second side rod 13. The first side rod 802 is installed on the inner wall of the stirring cylinder 1 through a bearing. One end of the first side rod 802 near the outside of the stirring cylinder 1 is fixedly connected with a swing rod 803. A support plate 11 is fixed on the outer wall of the stirring cylinder 1. A hydraulic push rod 804 is connected between the swing rod 803 and the support plate 11 through a movable shaft. Both the first side rod 802 and the second side rod 13 are movably sleeved on the end of the stirring rod 12. The valve plate 801 is arranged in an arc structure.

[0039] During specific implementation, since the existing agricultural waste organic fertilizer fermentation equipment usually sets the stirring paddle in the fermentation chamber, after the materials are fully stirred and mixed by the stirring paddle, they are directly fermented in the fermentation chamber. However, this fermentation method is easily affected by the stirring paddle and is prone to incomplete fermentation. After the stirring motor 10 drives the stirring rod 12 to rotate to stir and mix the materials, the hydraulic push rod 804 can be started to make the hydraulic push rod 804 extend to push one end of the swing rod 803 to rotate around one end of the first side rod 802. Since the swing rod 803 and the first side rod 802 are fixedly connected, the swing rod 803 drives the first side rod 802 to rotate. Subsequently, the first side rod 802 drives the valve plate 801 to rotate. At the same time, one end of the valve plate 801 drives the second side rod 13 to rotate outside the stirring rod 12, and the valve plate 801 can be opened to enable the stirred and mixed materials to slide into the fermentation cylinder 5. The materials can be fully fermented in the fermentation cylinder 5. After fermentation is completed, the sealing door 6 is opened to take out the materials fermented into organic fertilizer. By setting the stirring cylinder 1 and the fermentation cylinder 5 separately, it is beneficial to carry out fermentation and stirring work simultaneously, and reduces the risks of microbial contamination and cross-contamination, improving the working quality of the agricultural waste organic fertilizer fermentation equipment.

[0040] In summary, when using this agricultural waste organic fertilizer fermentation equipment, the material enters from the crushing feed hopper 2. By setting a rotatable rod 26 and a stirring paddle 27 that can reciprocate and rotate at the bottom feed port of the crushing feed hopper 2, the material accumulated at the feed port can be turned over and dispersed to prevent accumulation. Moreover, the telescopic mechanism 7 that provides power to the rotatable rod 26 and the stirring paddle 27 operates simultaneously with the stirring motor 10 and the crushing motor 20. There is no need to set an additional driving component on the telescopic mechanism 7. The stirring motor 10 and the crushing motor 20 can promote the efficiency of material flow while stirring and crushing the material, reducing energy consumption and improving the operating efficiency of the equipment. Subsequently, the feeding mechanism 8 is started, and the stirred material enters the fermentation cylinder 5 from the feeding cavity 16. The separate setting of the fermentation cylinder 5 and the stirring cylinder 1 is conducive to simultaneous fermentation and stirring operations, reduces the risk of microbial contamination and cross-contamination, and improves the working quality and practicability of the agricultural waste organic fertilizer fermentation equipment. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
