Description

Technical Field

[0001] This invention relates to the field of rice straw fermentation and returning to the field, specifically to a rice straw returning to the field equipment and method based on microbial fermentation. Background Technology

[0002] Returning rice straw to the field is a measure that utilizes straw for soil improvement and yield enhancement. It is an important method for increasing soil fertility, eliminating air pollution caused by straw burning while also increasing soil fertility and yield. Because rice straw decomposes slowly in the natural environment, it needs to be crushed and then fermented using microorganisms to quickly decompose it, thus rapidly increasing soil fertility and improving the soil environment. During fermentation, to ensure effective decomposition, the rice straw needs to be piled into fermentation heaps. To prevent excessively high temperatures inside the fermentation heap from affecting microbial growth, the heaps need to be turned and aerated regularly, and water needs to be replenished promptly.

[0003] Existing rice straw fermentation and returning equipment cannot maintain a certain height of the fermentation pile while simultaneously turning the rice straw for fermentation. This requires workers to stack the rice straw fermentation pile later, increasing their labor intensity. Furthermore, it cannot accurately add water to the rice straw fermentation pile, resulting in uneven moisture distribution inside the pile. This prevents microorganisms from multiplying properly and affects the effectiveness of rice straw fermentation and returning to the field.

[0004] Combining the above problems, we find that existing rice straw fermentation and returning equipment is difficult to avoid all of the aforementioned issues when in use. Even if it can solve these problems, it requires the assistance of external tools, thus failing to achieve the desired effect. Therefore, we propose a rice straw returning equipment and method based on microbial fermentation. Summary of the Invention

[0010] Preferably, a stabilizing base is fixedly connected to the right side of the servo motor, and the bottom surface of the stabilizing base is fixedly connected to the upper surface of the support frame.

[0011] Preferably, the outer surfaces of the two first connecting shafts are rotatably connected to limit frames, and the sides of the two limit frames that are far apart from each other are respectively fixedly connected to the sides of the two guide plates that are close to each other.

[0016] A rice straw returning-to-field device and method based on microbial fermentation, comprising the following steps:

[0017] S1: The power provided by the rotary motor, together with the guide plate and the stabilizing frame, can drive the rotating shaft to rotate. As the rotating shaft rotates, it can drive the dispersing blade to rotate quickly. At this time, the rapidly rotating dispersing blade can initially dissipate the rice straw fermentation pile, making the rice straw fermentation pile more loose, so that the subsequent secondary turning and secondary stacking of the rice straw fermentation pile is smoother and more convenient.

[0018] S2: By utilizing the inclination of the guide plate, the scattered rice straw can be regrouped. Furthermore, through the inclination of the inclined plate and the fixed plate, the rice straw can be re-stacking into a pile. This allows the rice straw to be quickly and easily re-stacking after fermentation, eliminating the need for workers to use tools for secondary stacking. This reduces the labor intensity of workers and ensures that the microorganisms inside the rice straw can continue to ferment and decompose smoothly. This makes it easier and faster to turn and stack the rice straw, allowing it to be returned to the field smoothly after fermentation. The drive wheel and driven wheel allow the device to move smoothly, ensuring the continuity of turning and secondary stacking of the rice straw fermentation pile.

[0019] S3: Utilizing the power provided by the servo motor in conjunction with the stable base and support frame, the first connecting shaft and the first spiral frame can be rotated via the first pulley and belt in conjunction with the second pulley. As the first spiral frame rotates, it guides the rice straw fermentation pile with the help of the guide plate. The spiral shape of the first spiral frame can be used to roll the rice straw upwards and finally let it fall down, thereby turning the rice straw fermentation pile over a second time. This allows the heat inside the rice straw fermentation pile to dissipate better and further increases the looseness of the rice straw fermentation pile. Furthermore, the first pulley in conjunction with the second connecting shaft can drive the second spiral frame to rotate. At this time, the second spiral frame can further turn over the rice straw fermentation pile in the middle part, so that the rice straw fermentation pile can be turned over more thoroughly before being stacked a second time.

[0020] S4: The water pump provides suction to draw out the water pre-filled in the storage tank and delivers it to the spray pipe through the water delivery pipe. With the help of the positioning frame, the water inside the spray pipe is sprayed through the first nozzle onto the rice straw being turned by the dispersing plate and the two first spiral frames. Then, with the help of the diversion pipe and the second nozzle, some water can be drawn out from the spray pipe and sprayed out from the second nozzle with the assistance of the reinforcement frame. This allows the rice straw being turned by the second spiral frame to also receive water spraying. Water can be evenly sprayed into the inside of the rice straw during the fermentation and turning process.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. This invention, by setting up a dispersing component, can initially break up and dissipate heat from piles of fermenting rice straw. Then, by using the inclination of the guide plate, the broken rice straw can be gathered back together. Furthermore, by using the inclination of the inclined plate in conjunction with the fixing plate, the rice straw can be re-piled. This allows the rice straw to be quickly piled up again after fermentation and turning, eliminating the need for workers to use tools for secondary stacking, reducing the labor intensity of workers, ensuring that the microorganisms inside the rice straw can continue to ferment and decompose smoothly, and making it easier and faster to turn and pile the rice straw, so that the fermented rice straw can be smoothly returned to the field.

[0023] 2. By setting up a dispersing component in conjunction with a turning component, the rice straw in fermentation can be turned over multiple times. This ensures the turning effect of the rice straw fermentation pile while increasing the smoothness of the secondary stacking of the rice straw fermentation pile. Through multiple turnings, the heat dissipation and ventilation efficiency of the rice straw fermentation pile can be improved, further ensuring that the microorganisms inside the rice straw fermentation pile can better ferment and decompose the rice straw.

[0024] 3. By setting up a spraying component in conjunction with a turning component and a dispersing component, the present invention can evenly spray water into the interior of the rice straw during the turning process of the rice straw fermentation pile. This makes the addition of water inside the rice straw fermentation pile more uniform, allowing a better microbial growth environment to be formed inside the rice straw fermentation pile, ensuring the fermentation efficiency of the rice straw fermentation pile, as well as the fertility of the rice straw fermentation and returning it to the field.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1: Please refer to Figures 1-8 This invention provides a technical solution: a rice straw returning device and method based on microbial fermentation, comprising two fixed plates 1, a stacking mechanism 2 jointly provided on the left side of the two fixed plates 1, the stacking mechanism 2 comprising two inclined plates 201, the side of the two inclined plates 201 that is far apart from each other being fixedly connected to the side of the two fixed plates 1 that is close to each other, the two inclined plates 201 are both at a certain inclination angle, the left side of the two inclined plates 201 is fixedly connected to a guide plate 202, the right side of the two guide plates 202 is fixedly connected to the left side of the two fixed plates 1, the two guide plates 202 are both at a certain inclination angle, the side of the two fixed plates 1 that is far apart from each other being fixedly connected to a drive wheel 203, and the side of the two guide plates 202 that is far apart from each other being fixedly connected to a driven wheel 204.

[0041] The specific implementation method of this embodiment is as follows: By utilizing the inclination of the guide plate 202, the scattered rice straw can be regrouped, and by using the inclination of the inclined plate 201 in conjunction with the fixed plate 1, the rice straw can be re-stacked into a pile, allowing the rice straw to be quickly re-stacked after fermentation and turning, without the need for workers to use tools for secondary stacking, reducing the labor intensity of workers, ensuring that the microorganisms inside the rice straw can continue to ferment and decompose smoothly, making it easier and faster to turn and stack the rice straw, so that the fermented rice straw can be smoothly returned to the field. The drive wheel 203 and the driven wheel 204 allow the device to move smoothly, ensuring the continuity of turning and secondary stacking of the rice straw fermentation pile.

[0042] Example 2: Please refer to Figure 2 and Figure 4 The present invention provides a technical solution: a rice straw returning equipment and method based on microbial fermentation. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The stacking mechanism 2 is provided with a dispersing component 3 inside.

[0043] As a further definition of the dispersion component 3 of the present invention, the dispersion component 3 includes a rotating shaft 301, which is rotatably connected to the interior of two guide plates 202. Each of the two guide plates 202 has a fixed seat 302 fixedly connected to its opposite side. Each of the two fixed seats 302 has a fixed motor 303 fixedly connected to its upper surface. The output ends of the two rotating motors 303 are respectively fixedly connected to the opposite ends of the rotating shaft 301. A plurality of dispersing paddles 304 are fixedly connected to the outer surface of the rotating shaft 301. Two stabilizing frames 305 are rotatably connected to the outer surface of the rotating shaft 301. The opposite sides of the two stabilizing frames 305 are respectively fixedly connected to the opposite sides of the two guide plates 202.

[0044] The specific implementation method of this embodiment is as follows: the power provided by the rotary motor 303, together with the guide plate 202 and the stabilizing frame 305, can drive the rotating shaft 301 to rotate. As the rotating shaft 301 rotates, it can drive the dispersing paddle 304 to rotate rapidly. At this time, the rapidly rotating dispersing paddle 304 can initially disperse the rice straw fermentation pile, making the rice straw fermentation pile dispersed into a relatively loose state, so that the subsequent secondary turning and secondary stacking of the rice straw fermentation pile is smoother and more convenient.

[0045] Example 3: Please refer to Figure 3 , Figure 5 and Figure 6 The present invention provides a technical solution: a rice straw returning equipment and method based on microbial fermentation. The present invention makes corresponding improvements to the technical problems mentioned in the background art. A turning component 4 is provided above the stacking mechanism 2.

[0046] As a further definition of the material turning assembly 4 of the present invention, the material turning assembly 4 includes a support frame 401, the upper surfaces of two guide plates 202 are fixedly connected to the bottom surface of the support frame 401, two first connecting shafts 402 are rotatably connected inside the support frame 401, and a first spiral bracket 403 is fixedly connected to the outer surface of the two first connecting shafts 402, a servo motor 404 is arranged above the support frame 401, a first pulley 405 is fixedly connected to the output end of the servo motor 404, a second pulley 406 is fixedly connected to the top end of the two first connecting shafts 402, two belts 407 are drive-connected to the outer surface of the first pulleys 405, and the two belts 407 are respectively drive-connected to the two second pulleys 406, a second connecting shaft 408 is rotatably connected inside the support frame 401, the top end of the second connecting shaft 408 is fixedly connected to the bottom end of the first pulley 405, and a second spiral bracket 409 is fixedly connected to the outer surface of the second connecting shaft 408.

[0047] A stabilizing base 410 is fixedly connected to the right side of the servo motor 404. The bottom surface of the stabilizing base 410 is fixedly connected to the upper surface of the support frame 401. The stabilizing base 410 can increase the stability of the servo motor 404, allowing the servo motor 404 to run stably and ensuring that the servo motor 404 can drive the first pulley 405 to rotate smoothly.

[0048] The outer surfaces of the two first connecting shafts 402 are rotatably connected to limit frames 411. The side of the two limit frames 411 that is far apart from each other is fixedly connected to the side of the two guide plates 202 that is close to each other. The limit frames 411 can limit the position of the first connecting shafts 402, so that the first connecting shafts 402 are not prone to excessive swinging when rotating, thereby improving the rotation reliability of the first connecting shafts 402.

[0049] An auxiliary frame 412 is rotatably connected to the outer surface of the second connecting shaft 408. The upper surface of the auxiliary frame 412 is fixedly connected to the bottom surface of the support frame 401. The auxiliary frame 412 can increase the structural strength of the second connecting shaft 408 and prevent the pressure on the second connecting shaft 408 from being transmitted to the first pulley 405, thus ensuring the stable rotation of the first pulley 405.

[0050] The specific implementation of this embodiment is as follows: Utilizing the power provided by the servo motor 404, in conjunction with the stabilizing base 410 and the support frame 401, the first connecting shaft 402 and the first spiral frame 403 are driven to rotate via the first pulley 405 and belt 407 in conjunction with the second pulley 406. As the first spiral frame 403 rotates, in conjunction with the guide plate 202 guiding the rice straw fermentation pile, the spiral shape of the first spiral frame 403 can be used to roll the rice straw upwards and finally drop it down, thereby performing a secondary turning of the rice straw fermentation pile. This allows the heat inside the rice straw fermentation pile to dissipate better, further... This step increases the looseness of the rice straw fermentation pile, and the first pulley 405, in conjunction with the second connecting shaft 408, can drive the second spiral frame 409 to rotate. At this time, the second spiral frame 409 can further turn the rice straw fermentation pile in the middle part, so that the rice straw fermentation pile can be turned more thoroughly before the second stacking. This allows the rice straw fermentation pile to be turned multiple times, improving the heat dissipation and ventilation efficiency of the rice straw fermentation pile, increasing the turning effect of the rice straw fermentation pile, and further ensuring that the microorganisms inside the rice straw fermentation pile can better ferment and decompose the rice straw.

[0051] Example 4: Please refer to Figure 5 , Figure 6 , Figure 7 and Figure 8The present invention provides a technical solution: a rice straw returning equipment and method based on microbial fermentation. The present invention makes corresponding improvements to the technical problems mentioned in the background art. A spraying component 5 is provided above the two fixed plates 1.

[0052] As a further definition of the spraying assembly 5 of the present invention, the spraying assembly 5 includes a water storage tank 501, the upper surfaces of two fixing plates 1 are fixedly connected to the upper surface of the water storage tank 501, the upper surfaces of two inclined plates 201 are fixedly connected to the bottom surface of the water storage tank 501, two water pumps 502 are fixedly connected to the left side of the water storage tank 501, the inlet ends of the two water pumps 502 penetrate into the interior of the water storage tank 501, the outlet ends of the two water pumps 502 are fixedly connected to a water delivery pipe 503, two positioning frames 510 are fixedly connected to the left side of the support frame 401, the inner walls of the two positioning frames 510 are jointly fixedly connected to a spray pipe 504, the other ends of the two water delivery pipes 503 are fixedly connected to the outer surface of the spray pipe 504, a plurality of first nozzles 505 are fixedly connected to the outer surface of the spray pipe 504, a diversion pipe 506 is fixedly connected to the outer surface of the spray pipe 504, and two second nozzles 507 are fixedly connected to the outer surface of the diversion pipe 506.

[0053] A water inlet pipe 508 is fixedly connected to the front of the water storage tank 501. A dust plug 509 is snapped onto the top of the water inlet pipe 508. The water inlet pipe 508 allows staff to easily add water into the water storage tank 501. The dust plug 509 prevents external impurities from entering the water storage tank 501 through the water inlet pipe 508, thus ensuring the cleanliness of the water inside the water storage tank 501.

[0054] Two reinforcing brackets 511 are fixedly connected to the outer surface of the drainage tube 506. The upper surfaces of the two reinforcing brackets 511 are fixedly connected to the bottom surface of the support frame 401. The reinforcing brackets 511 can fix the position of the drainage tube 506, so that the drainage tube 506 is not prone to excessive shaking during use, thus ensuring the reliability of the drainage tube 506.

[0055] The specific implementation of this embodiment is as follows: the suction provided by the water pump 502 can draw out the water pre-filled inside the water storage tank 501 and send it into the spray pipe 504 through the water delivery pipe 503. The water inside the spray pipe 504, with the cooperation of the positioning frame 510, is sprayed through the first nozzle 505 onto the rice straw being turned over by the dispersing plate 304 and the two first spiral frames 403. Then, using the diversion pipe 506 in conjunction with the second nozzle 507, some of the water can be diverted from the spray pipe 504. The water is sprayed out from the second nozzle 507 with the assistance of the reinforcing frame 511, so that the rice straw during the turning process of the second spiral frame 409 can also be sprayed with water. During the turning process of the rice straw fermentation pile, the water can be evenly sprayed into the inside of the rice straw, so that the water is added more evenly inside the rice straw fermentation pile, which can create a better microbial growth environment inside the rice straw fermentation pile, ensuring the fermentation efficiency of the rice straw fermentation pile and the fertility of rice straw fermentation and returning to the field.

[0056] Specifically, this rice straw returning equipment based on microbial fermentation operates as follows:

[0057] First, the power provided by the rotary motor 303, together with the guide plate 202 and the stabilizing frame 305, can drive the rotating shaft 301 to rotate. As the rotating shaft 301 rotates, it can drive the dispersing paddle 304 to rotate quickly. At this time, the rapidly rotating dispersing paddle 304 can initially disperse the rice straw fermentation pile, making the rice straw fermentation pile dispersed into a relatively loose state, making the subsequent secondary turning and secondary stacking of the rice straw fermentation pile smoother and more convenient.

[0058] Then, by using the inclination of the guide plate 202, the scattered rice straw can be gathered together again. And by using the inclination of the inclined plate 201 in conjunction with the fixed plate 1, the rice straw can be re-stacked into a pile. This allows the rice straw to be quickly re-stacked after fermentation and turning, eliminating the need for workers to use tools for secondary stacking, reducing the labor intensity of workers, and ensuring that the microorganisms inside the rice straw can continue to ferment and decompose smoothly. This makes it easier and faster to turn and stack the rice straw, allowing the fermented rice straw to be returned to the field smoothly. Furthermore, the drive wheel 203 in conjunction with the driven wheel 204 allows the device to move smoothly, ensuring the continuity of turning and secondary stacking of the rice straw fermentation pile.

[0059] Furthermore, the power provided by the servo motor 404, in conjunction with the stabilizing seat 410 and the support frame 401, enables the first connecting shaft 402 and the first spiral frame 403 to rotate via the first pulley 405 and belt 407 in conjunction with the second pulley 406. As the first spiral frame 403 rotates, in conjunction with the guide plate 202 guiding the rice straw fermentation pile, the spiral shape of the first spiral frame 403 can be used to roll the rice straw upwards and finally drop it down, thereby enabling a secondary turning of the rice straw fermentation pile. This allows the heat inside the rice straw fermentation pile to dissipate better, further increasing the looseness of the rice straw fermentation pile. Moreover, the first pulley 405, in conjunction with the second connecting shaft 408, can drive the second spiral frame 409 to rotate. At this time, the second spiral frame 409 can further turn the rice straw fermentation pile in the middle section, allowing the rice straw fermentation pile to be turned more thoroughly before the secondary stacking.

[0060] Finally, the suction provided by the water pump 502 can draw out the water pre-filled inside the water storage tank 501 and send it into the spray pipe 504 through the water delivery pipe 503. With the cooperation of the positioning frame 510, the water inside the spray pipe 504 is sprayed through the first nozzle 505 onto the rice straw being turned by the dispersing plate 304 and the two first spiral frames 403. Then, with the help of the diversion pipe 506 and the second nozzle 507, some water can be drawn out from the spray pipe 504 and sprayed out from the second nozzle 507 with the assistance of the reinforcing frame 511. This allows the rice straw being turned by the second spiral frame 409 to also be sprayed with water. Water can be evenly sprayed into the inside of the rice straw during the turning process of the rice straw fermentation pile.

7. The method of using a rice straw returning equipment based on microbial fermentation according to any one of claims 1-6, characterized in that: Specifically, it includes the following steps; S1: The power provided by the rotary motor (303) in conjunction with the guide plate (202) and the stabilizing frame (305) can drive the rotating shaft (301) to rotate. As the rotating shaft (301) rotates, it can drive the dispersing paddle (304) to rotate quickly. At this time, the rapidly rotating dispersing paddle (304) can initially dissipate the rice straw fermentation pile, making the rice straw fermentation pile more loose, so that the subsequent secondary turning and secondary stacking of the rice straw fermentation pile is smoother and more convenient. S2: By using the inclination of the guide plate (202), the scattered rice straw can be gathered together again. And by using the inclination of the inclined plate (201) in conjunction with the fixed plate (1), the rice straw can be re-stacked into a pile. After the rice straw ferments and is turned over, it can be quickly re-stacked into a pile without the need for workers to use tools to stack it a second time, which reduces the labor intensity of workers and ensures that the microorganisms inside the rice straw can continue to ferment and decompose smoothly. This makes it easier and faster to turn the rice straw over and stack it into a pile, so that the fermented rice straw can be returned to the field smoothly. Furthermore, by using the drive wheel (203) in conjunction with the driven wheel (204), the equipment can be moved smoothly, ensuring the continuity of turning and secondary stacking of the rice straw fermentation pile. S3: Using the power provided by the servo motor (404) in conjunction with the stabilizing seat (410) and the support frame (401), the first connecting shaft (402) and the first spiral frame (403) can be driven to rotate through the first pulley (405) and the belt (407) in conjunction with the second pulley (406). As the first spiral frame (403) rotates, in conjunction with the guide plate (202) to gather and guide the rice straw fermentation pile, the spiral shape of the first spiral frame (403) can be used to roll the rice straw upwards and finally fall down. This allows for a secondary turning of the rice straw fermentation pile, enabling better dissipation of heat from the inside of the rice straw fermentation pile and further increasing the looseness of the rice straw fermentation pile. Furthermore, the first pulley (405) in conjunction with the second connecting shaft (408) can drive the second spiral frame (409) to rotate. At this time, the second spiral frame (409) can further turn the rice straw fermentation pile in the middle part, allowing the rice straw fermentation pile to be turned more thoroughly before the second stacking. S4: The suction provided by the water pump (502) can draw out the water pre-filled inside the water storage tank (501) and send it into the spray pipe (504) through the water delivery pipe (503). With the cooperation of the positioning frame (510), the water inside the spray pipe (504) is sprayed through the first nozzle (505) onto the rice straw being turned over by the dispersing plate (304) and the two first spiral frames (403). Then, with the cooperation of the diversion pipe (506) and the second nozzle (507), some water can be drawn out from the spray pipe (504) and sprayed out from the second nozzle (507) with the assistance of the reinforcing frame (511). This allows the rice straw being turned over by the second spiral frame (409) to also be sprayed with water. The water can be evenly sprayed into the inside of the rice straw during the fermentation and turning process of the rice straw pile.
