Description

Technical Field

[0001] The present invention relates to the field of fertilizer production equipment, and more specifically to an organic fertilizer stirring and fermenting device. Background Art

[0002] Organic solid waste can be processed into organic fertilizer after fermentation, deodorization, and maturity. Organic fertilizer is green and environmentally friendly, and it can condition the soil and increase the air permeability of the soil. At present, there are mainly two ways to produce organic fertilizer, namely compost fermentation or adding microbial strains for fermentation;

[0003] For compost fermentation, it requires open-air composting treatment, with slow heating and long fermentation time. The fermentation process is not easy to control, and the fermentation may not be complete. The produced organic fertilizer may retain pathogenic bacteria, eggs, and weed seeds.

[0004] For fermentation with the addition of microbial strains, it mainly involves placing the organic solid waste to be fermented into a container and adding microbial strains into the container. The container is equipped with a stirring component, so as to stir and mix the organic solid waste and the microbial strains, and then carry out the fermentation process. Due to the addition of microbial strains and the combined stirring effect, the fermentation process is rapid and relatively complete;

[0005] In the prior art, for the stirring component in the above-mentioned container, it mainly uses a stirring shaft and stirring teeth fixed on the stirring shaft. Due to the certain singularity of the movement form of the stirring teeth, the materials in the container may not be fully stirred, thereby reducing the fermentation rate and affecting the fermentation effect.

[0006] Therefore, how to provide an organic fertilizer stirring and fermenting device that can overcome the above problems is an urgent problem to be solved by those skilled in the art. Summary of the Invention

Specific embodiments

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below. 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 efforts shall fall within the protection scope of the present invention.

[0031] The present invention discloses an organic fertilizer stirring and fermenting device. By designing the feed bin 1, the organic fertilizer raw materials can be reliably arranged in the feed bin 1 and the fermentation process can be successfully completed;

[0032] By designing the stirring assembly, the stirring assembly in the present application is different from the conventional stirring of stirring teeth. The organic fertilizer raw materials near the bottom in the feed bin 1 can be conveyed to the upper end of the conduit 2 through the conduit 2, the main shaft one 3 and the spiral tooth one 4. The organic fertilizer raw materials in the conduit 2 are discharged from the upper end of the conduit 2, and the discharged organic fertilizer raw materials fall onto the high-speed rotating annular turntable 6 and are immediately thrown out. In this way, the organic fertilizer raw materials in the feed bin 1 will realize up and down circulation, thus playing a role in stirring. At the same time, the thrown out organic fertilizer raw materials can also be in full contact with the air, so as to ensure the fermentation effect; there are no components such as stirring teeth in the feed bin 1, relying on the throwing out and mixing of the organic fertilizer raw materials, and the organic fertilizer raw materials at the bottom of the feed bin 1 can also be in full contact with the air;

[0033] By designing the discharge port and the baffle plate 11, the organic fertilizer raw materials can be discharged through the discharge port after fermentation;

[0034] By designing the retaining disc 8, the organic fertilizer raw materials can fall smoothly onto the annular turntable 6 when discharged from the upper end of the conduit 2, and the organic fertilizer raw materials will not stain the drive motor two 7;

[0035] The drive motor two 7 can reliably drive the annular turntable 6 to rotate;

[0036] By designing the material guiding component, the spiral teeth II 14 in the material guiding component can drive the organic fertilizer raw materials near the bottom in the material box 1 to approach the feeding port 20, facilitating the entry of the organic fertilizer raw materials into the conduit 2; when the vibrator 16 in the material guiding component is started, it can drive the material box 1 and the organic fertilizer raw materials in the material box 1 to vibrate. Combining with the material guiding effect of the spiral teeth II 14, it further ensures that the organic fertilizer raw materials in the material box 1 can smoothly enter the conduit 2.

[0037] Embodiment

[0038] See Appendix Figures 1-6 It is a schematic diagram of the overall and partial structures of an implementation manner of the present invention. The present invention specifically discloses an organic fertilizer stirring and fermenting device, including:

[0039] The material box 1 is vertically arranged with an open upper end, and the bottom of the material box 1 is in a hopper shape. Such a design facilitates the downward movement of the organic fertilizer raw materials in the material box 1 to the lowest point in the material box 1;

[0040] The stirring component includes a conduit 2, a main shaft I 3, spiral teeth I 4, a driving machine I 5, an annular turntable 6, and a driving machine II 7.

[0041] The conduit 2 with a circular cross-sectional inner and outer contour is vertically fixed in the material box 1. The upper end of the conduit 2 is open and the lower end is closed. A feeding port 20 is provided on the conduit 2, and the feeding port 20 is arranged near the lower end of the conduit 2. The organic fertilizer raw materials located at the bottom of the material box 1 can enter the feeding port 20 by gravity or the extrusion of the upper materials; the particle size of the organic fertilizer raw materials added to the material box 1 is smaller than the caliber of the feeding port 20.

[0042] The main shaft I 3 with a circular cross-sectional outer contour is coaxially rotatably installed in the conduit 2; the spiral teeth I 4 are coaxially fixed on the main shaft I 3, and the spiral teeth I 4 are located inside the conduit 2, and the gap between the spiral teeth and the inner wall of the conduit 2 is very small.

[0043] The driving machine I 5 is connected to the material box 1, and the output rotating shaft of the driving machine I 5 is coaxially fixed to the main shaft I 3. The driving machine I 5 can drive the main shaft I 3 to rotate. When the main shaft I 3 rotates, the combined action of the spiral teeth I 4 and the conduit 2 enables the organic fertilizer raw materials entering the conduit 2 from the feeding port 20 to be guided upward, and the organic fertilizer raw materials in the conduit 2 can be discharged from the upper end of the conduit 2.

[0044] The annular turntable 6 is coaxially and rotatably mounted on the conduit 2. The conduit 2 is located inside the annular turntable 6. The annular turntable 6 is arranged near the upper end of the conduit 2. The upper end surface of the annular turntable 6 is located below the upper end wall of the conduit 2. The upper end of the conduit 2 is integrally formed with an annular flange outward. The outer diameter of the annular flange is greater than the inner diameter of the annular turntable 6. The annular flange is located above the annular turntable 6. The purpose of this design is that the organic fertilizer raw materials discharged from the upper end of the conduit 2 will not enter the gap between the annular turntable 6 and the conduit 2, and the organic fertilizer raw materials falling on the annular turntable 6 can be reliably thrown out.

[0045] The second drive motor 7 is mounted on the conduit 2 and is in driving connection with the annular turntable 6. The second drive motor 7 can drive the annular turntable 6 to rotate at a high speed. The organic fertilizer raw materials discharged from the upper end of the conduit 2 will fall onto the annular turntable 6. Due to the high-speed rotation of the annular turntable 6, the organic fertilizer raw materials falling on the annular turntable 6 will be quickly thrown out in all directions. The thrown organic fertilizer raw materials will fall. The organic fertilizer raw materials at the bottom of the material box 1 are guided by the first spiral teeth 4 to the upper end of the conduit 2 and thrown out. Therefore, the organic fertilizer raw materials in the entire material box 1 realize up and down reciprocating circulation, thus playing a role in stirring. At the same time, the organic fertilizer raw materials are stacked in the material box 1. The first drive motor 5 and the second drive motor 7 work regularly. During the period when the first drive motor 5 and the second drive motor 7 are stopped, the organic fertilizer raw materials can be fermented. The organic fertilizer raw materials thrown out by the annular turntable 6 can not only play a role in mixing and stirring, but also play a role in full contact with the air, ensuring that the organic fertilizer raw materials can be normally fermented.

[0046] The highest point of the organic fertilizer raw materials in the material box 1 cannot be higher than the second drive motor 7, that is, the organic fertilizer raw materials in the material box 1 will not contaminate the second drive motor 7.

[0047] The lower end of the conduit 2 is fixed at the lowest point of the inner bottom wall of the material box 1, so that the organic fertilizer raw materials in the material box 1 can smoothly enter the conduit 2 by relying on gravity and the downward pressure of the upper materials.

[0048] The bottom wall of the material box 1 is provided with a discharge port, and a baffle plate 11 is blocked at the discharge port. Opening the baffle plate 11 can discharge the material box 1. At the same time, the design of the discharge port is also convenient for cleaning and maintaining the inside of the material box 1.

[0049] There are multiple feed ports 20, and the multiple feed ports 20 are evenly arranged around the circumference of the conduit 2. The organic fertilizer raw materials in the material box 1 can smoothly enter the conduit 2.

[0050] A cross beam 12 is horizontally fixed inside the material box 1. The first drive motor 5 is fixed on the cross beam 12. The first main shaft 3 is arranged below the cross beam 12. The first drive motor 5 can be reliably fixed inside the material box 1.

[0051] More specifically, the stirring assembly further includes a baffle plate 8. The output rotating shaft of the first driving machine 5 and the first main shaft 3 are respectively and coaxially fixed to the upper and lower disk surfaces of the baffle plate 8. The baffle plate 8 is located above the conduit 2. The outer contour diameter of the baffle plate 8 is larger than the outer diameter of the conduit 2. There is a discharging gap between the lower disk surface of the baffle plate 8 and the upper end wall of the conduit 2. On the premise of ensuring that the organic fertilizer raw materials can be discharged from the upper end of the conduit 2, by designing the baffle plate 8, the baffle plate 8 can block the organic fertilizer raw materials discharged from the upper end of the conduit 2, and the baffle plate 8 can force the organic fertilizer raw materials to fall downward onto the annular turntable 6. The baffle plate 8 can also play a protective role to prevent the organic fertilizer raw materials from soiling the second driving machine 7 above.

[0052] More specifically, the stirring assembly further includes a gear 9 and a gear ring 10. The second driving machine 7 is fixed outside the conduit 2. The gear 9 is coaxially fixed to the output rotating shaft of the second driving machine 7. The gear ring 10 is coaxially rotatably installed on the conduit 2. The conduit 2 is located inside the gear ring 10. The annular turntable 6 is coaxially fixed to the gear ring 10. The gear 9 meshes with the gear ring 10. The number of teeth of the gear ring 10 is more than that of the gear 9. The second driving machine 7 can reliably drive the annular turntable 6 to rotate.

[0053] A plurality of teeth 60 are integrally formed on the upper disk surface of the annular turntable 6. The plurality of teeth 60 are evenly arranged circumferentially around the annular turntable 6. The organic fertilizer raw materials falling onto the annular turntable 6 can be smoothly thrown out.

[0054] More specifically, it further includes a material guiding assembly. The material guiding assembly includes a second main shaft 13, a second spiral tooth 14, a third driving machine 15 and a vibrator 16. The second main shaft 13 is rotatably installed in the material box 1. The rod center line of the second main shaft 13 is arranged obliquely with respect to the pipe center line of the conduit 2. The lower end of the second main shaft 13 is arranged close to the feed port 20. The upper end of the second main shaft 13 is arranged close to the upper end of the conduit 2. There are a plurality of second main shafts 13 and they are evenly arranged circumferentially with the pipe center line of the conduit 2 as the center; A second spiral tooth 14 is coaxially fixed on each second main shaft 13. There are a plurality of third driving machines 15 and they are all fixed on the material box 1. The output rotating shafts of the plurality of third driving machines 15 are respectively coaxially fixed to the upper ends of the plurality of second main shafts 13; The third driving machine 15 can drive the second spiral tooth 14 to rotate. Since the second main shaft 13 is arranged obliquely with respect to the conduit 2, the organic fertilizer raw materials deposited at the bottom of the material box 1 can be guided by the second spiral tooth 14 to near the feed port 20, and the organic fertilizer raw materials deposited at the bottom of the material box 1 can smoothly enter the conduit 2;

[0055] The vibrator 16 is fixed on the outer bottom wall of the material box 1; The vibration effect of the vibrator 16 is combined with the material guiding effect of the second spiral tooth 14 to ensure that the organic fertilizer raw materials in the material box 1 can smoothly enter the conduit 2.

[0056] A cover plate (not shown in the figure) can be provided on the top of the material box 1. The cover plate can play a role in heat preservation and sealing, which helps to improve the fermentation rate.

[0057] The outer side wall of the material box 1 can be wound with heating wires (not shown in the figure). After the heating wires are energized, the material box 1 and the organic fertilizer raw materials in the material box 1 can be heated, thereby increasing the fermentation rate.

[0058] When the device is in use, first, a certain amount of organic fertilizer raw materials are added to the material box 1, and it is ensured that the highest point of the organic fertilizer raw materials added to the material box 1 is not higher than the second drive 7; then the first drive 5, the second drive 7, the third drive 15 and the vibrator 16 are started regularly. The organic fertilizer raw materials in the material box 1 will enter the conduit 2 from the feed port 20, and then be discharged from the upper end of the conduit 2. The discharged organic fertilizer raw materials will fall onto the annular turntable 6. The high-speed rotating annular turntable 6 will quickly throw out the organic fertilizer raw materials, thereby realizing the transfer of the organic fertilizer raw materials at the bottom of the material box 1 to the surface of the organic fertilizer raw materials in the material box 1, thus realizing the up and down circulation and stirring of the organic fertilizer raw materials, and at the same time increasing the contact area between the organic fertilizer raw materials and the air; when the fermentation is completed, the baffle 11 can be opened for discharging.

[0059] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. The same or similar parts among the embodiments can be referred to each other.

[0060] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention.
