Description

Technical Field

[0001] This utility model relates to the field of spreading machine technology, and specifically discloses a sugarcane leaf returning to the field enzymatic hydrolysis-microorganism combined spreading machine. Background Technology

[0002] Returning sugarcane leaves to the field is a crucial measure for achieving a green agricultural cycle in the sugarcane planting industry. By converting the sugarcane leaves remaining after harvest into organic matter for farmland, it avoids the air pollution and resource waste caused by traditional incineration, significantly improves soil structure, increases soil organic matter content, enhances soil water and fertilizer retention capacity, and provides long-lasting nutrients for subsequent sugarcane growth, reducing fertilizer use and lowering planting costs. Enzymatic hydrolysis-microbial combined technology is a key means to improve the efficiency of sugarcane leaf return to the field: cellulase can efficiently decompose recalcitrant components such as cellulose and hemicellulose in sugarcane leaves, converting them into small-molecule sugars that are easily utilized by microorganisms; while functional microorganisms such as Azotobacter chrysogenum can further degrade organic matter, fix nitrogen from the air, replenish soil nitrogen sources, accelerate the decomposition process of sugarcane leaves, and achieve a synergistic effect of "degradation-fertilization," significantly shortening the return cycle and improving the return effect.

[0003] However, existing sugarcane leaf return equipment has significant shortcomings in practical applications: On the one hand, existing equipment requires the sugarcane leaves to be crushed first, and the crushed material is transported by a conveyor belt. During the transport process, cellulase and azotocinobacter thuringiensis are sprayed. However, due to the lack of a material equalization mechanism, uneven material distribution is likely to occur after the sugarcane leaves are fed and crushed, with prominent local accumulation or scattering. This makes it difficult for the enzymatic hydrolysate and microbial agents to contact the material evenly. In some areas, insufficient reagents affect the degradation efficiency, while in other areas, excessive reagents cause waste. On the other hand, traditional equipment mostly adopts a step-by-step spraying method, that is, cellulase is sprayed when the material is transported to the first area, and azotocinobacter thuringiensis is sprayed when it is transported to the second area. It is impossible to achieve simultaneous spraying of the two reagents, which not only prolongs the processing process but also requires the additional installation of multiple sets of conveying and spraying components, significantly increasing the complexity of the equipment structure.

[0004] Therefore, a combined enzymatic hydrolysis and microbial application machine for sugarcane leaf return to the field is needed to solve the above problems. Utility Model Content

[0005] This invention proposes a combined enzymatic hydrolysis and microbial application machine for sugarcane leaf return to the field, which ensures that the crushed material falls evenly, avoiding local accumulation or scattering, thereby improving the uniformity of material-reagent contact. This prevents degradation efficiency from being affected by insufficient reagents and also avoids waste caused by excessive reagents. At the same time, the simultaneous spraying of two liquids effectively shortens the processing flow and reduces the complexity of the equipment structure.

[0006] This utility model is implemented as follows: a sugarcane leaf returning to the field enzymatic hydrolysis-microorganism combined application machine includes a raw material box, the lower end of which is connected to an L-shaped frame, an auxiliary feeding mechanism and a dual-liquid spraying mechanism are arranged below the raw material box, a crushing mechanism is arranged below the auxiliary feeding mechanism, and a uniform material mechanism is arranged below the crushing mechanism.

[0007] The material leveling mechanism includes a material leveling roller rotatably connected inside an L-shaped frame. The outer wall of the material leveling roller has multiple material leveling grooves evenly distributed circumferentially. The left and right ends of the inner wall of the L-shaped frame are fixedly connected to the outer wall of the material leveling roller with a clearance fit. The upper ends of the two first sealing blocks are fixedly connected to the first guide strip with a triangular cross-section. The outer wall of the L-shaped frame is equipped with a first drive motor whose output end is fixedly connected to the material leveling roller.

[0008] The dual-liquid spraying mechanism includes a box body fixedly connected to the outer wall of an L-shaped frame. A partition is fixedly connected inside the box body, dividing the space inside the box body into a cellulase chamber and a brown ammonia-fixing bacteria suspension chamber. A booster pump is installed on the outer wall of the box body. The water inlet of the booster pump is connected to a first curved pipe extending into the cellulase chamber. The outer wall of the first curved pipe is connected to a first straight pipe extending into the brown ammonia-fixing bacteria suspension chamber. Two material pipes are arranged inside the L-shaped frame. The lower ends of the two material pipes are connected to multiple atomizing nozzles evenly distributed front and back. A second curved pipe is connected between the water outlet of the booster pump and the material pipe located on the left side. A second straight pipe is connected between the second curved pipe and the material pipe located on the right side.

[0009] As a preferred embodiment of the sugarcane leaf returning to the field enzymatic hydrolysis-microorganism combined application machine of this utility model, the auxiliary feeding mechanism includes a rotating shaft rotatably connected inside the L-shaped frame, a plurality of material turning plates are fixedly connected to the outer wall of the rotating shaft, a second sealing block is fixedly connected to both the left and right ends of the inner wall of the L-shaped frame, a second guide strip with a triangular cross-section is fixedly connected to the upper end of each of the two second sealing blocks, and a second drive motor with its output end fixedly connected to the rotating shaft is installed on the outer wall of the L-shaped frame.

[0010] As a preferred embodiment of the sugarcane leaf returning to the field enzymatic hydrolysis-microorganism combined application machine of this utility model, the crushing mechanism includes turntables respectively rotatably connected to the front and rear sides of the inner wall of the L-shaped frame, multiple connecting rods fixedly connected between the two turntables, multiple evenly distributed annular grooves opened on the outer walls of the multiple connecting rods, movable sleeves with clearance fits are provided inside the multiple annular grooves, and blades are fixedly connected to the outer walls of the multiple movable sleeves. A third drive motor with its output end fixedly connected to one of the turntables is installed on the outer wall of the L-shaped frame, and an arc-shaped mesh plate is fixedly connected inside the L-shaped frame.

[0011] As a preferred embodiment of the sugarcane leaf returning to the field enzymatic hydrolysis-microorganism combined application machine of this utility model, the right end of the L-shaped frame is provided with a discharge port, and the bottom end of the inner wall of the L-shaped frame is fixedly connected with a guide block, which extends into the discharge port and has an inclined structure at the top.

[0012] In the preferred embodiment of the sugarcane leaf returning to the field enzymatic hydrolysis-microorganism combined application machine of this utility model, the bottom of the raw material box is fixedly connected to a guide block with an inclined upper surface.

[0013] In a preferred embodiment of the sugarcane leaf returning to the field enzymatic hydrolysis-microorganism combined application machine of this utility model, multiple fixing rods are fixedly connected to the outer walls of both material pipes, and the other ends of the multiple fixing rods are fixedly connected to the inner wall of the L-shaped frame.

[0014] The beneficial effects of this utility model are:

[0015] 1. The pulverized material is evenly tumbled and pushed downwards by the uniformly rotating and receiving rollers. The material is then uniformly conveyed to the guide block and slides to the right. This uniform feeding process avoids local accumulation or scattering, and improves the uniformity of material-reagent contact during subsequent reagent spraying. This prevents both insufficient reagent from affecting degradation efficiency and excessive reagent from causing waste.

[0016] 2. As the crushed material slides along the guide block, the dual-liquid spraying mechanism is activated. The chamber, separated by a partition, contains two reagents: a cellulase chamber and a *Brachycoccus pluvialis* suspension chamber. A booster pump simultaneously draws reagents from both chambers and delivers them to the left and right feed pipes, which are then synchronously and evenly sprayed onto the surface of the crushed material through atomizing nozzles below the feed pipes. This dual-liquid synchronous spraying design effectively shortens the processing time, eliminates the need for multiple additional conveying and spraying components, and reduces the complexity of the equipment structure.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0025] Please see Figure 1-5 The sugarcane leaf return to the field enzymatic hydrolysis-microorganism combined application machine includes a raw material box 1, an L-shaped frame 2 connected to the lower end of the raw material box 1, an auxiliary feeding mechanism and a double liquid spraying mechanism set below the raw material box 1, a crushing mechanism set below the auxiliary feeding mechanism, and a uniform material mechanism set below the crushing mechanism.

[0026] The material leveling mechanism includes a material leveling roller 4 rotatably connected inside the L-shaped frame 2. The outer wall of the material leveling roller 4 is provided with multiple material leveling grooves evenly distributed along the circumference. The left and right ends of the inner wall of the L-shaped frame 2 are fixedly connected to the outer wall of the material leveling roller 4 with a clearance fit. The upper ends of the two first sealing blocks 3 are fixedly connected to the first guide strip with a triangular cross section. The outer wall of the L-shaped frame 2 is equipped with a first drive motor 6 whose output end is fixedly connected to the material leveling roller 4.

[0027] The dual-liquid spraying mechanism includes a box 7 fixedly connected to the outer wall of the L-shaped frame 2. A partition 8 is fixedly connected inside the box 7, which divides the space inside the box 7 into a cellulase chamber 9 and a brown ammonia-fixing bacteria suspension chamber 10. A booster pump 11 is installed on the outer wall of the box 7. The water inlet of the booster pump 11 is connected to a first bent pipe 12 extending into the cellulase chamber 9. The outer wall of the first bent pipe 12 is connected to a first straight pipe 14 extending into the brown ammonia-fixing bacteria suspension chamber 10. Two feed pipes 16 are arranged inside the L-shaped frame 2. The lower ends of the two feed pipes 16 are connected to multiple atomizing nozzles 17 evenly distributed front and back. A second bent pipe 13 is connected between the water outlet of the booster pump 11 and the feed pipe 16 on the left side. A second straight pipe 15 is connected between the second bent pipe 13 and the feed pipe 16 on the right side.

[0028] In this embodiment: During use, the sugarcane leaves to be processed are stored in the raw material box 1. An auxiliary feeding mechanism ensures that the sugarcane leaves enter the crushing mechanism below at a stable flow rate.

[0029] At the same time, the crushing mechanism starts working to crush and cut the falling sugarcane leaves; only crushed material with the required particle size can enter the uniform material mechanism below, so as to control the particle size of the crushed sugarcane leaves.

[0030] The crushed material accumulates on the upper side of the leveling roller 4. Simultaneously, the first drive motor 6 drives the leveling roller 4 to rotate inside the L-shaped frame 2. The multiple leveling grooves of the leveling roller 4 receive the crushed material, and as the leveling roller 4 rotates at a constant speed, it pushes the crushed material downwards evenly. The first sealing blocks 3 at both ends of the inner wall of the L-shaped frame 2 are fitted with the outer wall of the leveling roller 4 to prevent the crushed material from leaking out from both sides. The first guide strip at its upper end guides the crushed material into the leveling groove. Under the continuous rotation of the leveling roller 4, the crushed material is evenly transported to the upper end of the guide block 18 at the bottom of the L-shaped frame 2. The guide block 18 guides the crushed material to slide to the right. In the above process, the leveling mechanism makes the crushed material fall evenly, avoiding local accumulation or scattering. When spraying reagents later, it can improve the uniformity of contact between the material and the reagent, preventing the degradation efficiency from being affected by insufficient reagents and avoiding waste caused by excessive reagents.

[0031] As the crushed material slides to the right along the guide block 18, the dual-liquid spraying mechanism is activated. The cellulase chamber 9 and the *Aminococcus globulus* suspension chamber 10, separated by the partition 8, store cellulase and *Aminococcus globulus* suspension, respectively. When the booster pump 11 is working, it draws cellulase from the cellulase chamber 9 through the first bend pipe 12, and simultaneously draws *Aminococcus globulus* suspension from the *Aminococcus globulus* suspension chamber 10 through the first straight pipe 14 connected to the outer wall of the first bend pipe 12. The two reagents enter the left-side feed pipe 16 through the outlet of the booster pump 11 and the second bend pipe 13, and enter the right-side feed pipe 16 through the second bend pipe 13 and the second straight pipe 15, respectively. Finally, they are sprayed synchronously through multiple atomizing nozzles 17 evenly distributed at the lower end of the two feed pipes 16, and evenly sprayed onto the surface of the crushed material. The sprayed crushed material is discharged from the outlet and spread in the field. This dual-liquid synchronous spraying design effectively shortens the processing flow, eliminates the need for multiple additional conveying and spraying components, and reduces the complexity of the equipment structure.

[0032] As a technical optimization of this utility model, the auxiliary feeding mechanism includes a rotating shaft 20 rotatably connected inside the L-shaped frame 2. Multiple flipping plates 21 are fixedly connected to the outer wall of the rotating shaft 20. Second sealing blocks 19 are fixedly connected to both the left and right ends of the inner wall of the L-shaped frame 2. A second guide strip with a triangular cross-section is fixedly connected to the upper end of each of the two second sealing blocks 19. A second drive motor 5 with its output end fixedly connected to the rotating shaft 20 is installed on the outer wall of the L-shaped frame 2.

[0033] In this embodiment: the auxiliary feeding mechanism is activated, and the second drive motor 5 drives the rotating shaft 20 to rotate. The multiple turning plates 21 on the outer wall of the rotating shaft 20 rotate accordingly, turning and pushing the sugarcane leaves that have entered the L-shaped frame 2 downwards. The second sealing blocks 19 at the left and right ends of the inner wall of the L-shaped frame 2 can prevent the sugarcane leaves from leaking out from the gaps on both sides. The second guide strip at its upper end further gathers the sugarcane leaves towards the middle, ensuring that the sugarcane leaves enter the crushing mechanism below with a stable flow rate.

[0034] As a technical optimization of this utility model, the crushing mechanism includes turntables 23 rotatably connected to the front and rear sides of the inner wall of the L-shaped frame 2, and multiple connecting rods 24 fixedly connected between the two turntables 23. The outer walls of the multiple connecting rods 24 are provided with multiple evenly distributed annular grooves. The interior of the multiple annular grooves is provided with movable sleeves 25 that are clearance-fitted with them. The outer walls of the multiple movable sleeves 25 are fixedly connected with throwing blades 26. The outer wall of the L-shaped frame 2 is equipped with a third drive motor 27 whose output end is fixedly connected to one of the turntables 23. The interior of the L-shaped frame 2 is fixedly connected with an arc-shaped mesh plate 22.

[0035] In this embodiment: When the crushing mechanism is working, the third drive motor 27 drives one of the turntables 23 to rotate. Since the two turntables 23 are fixedly connected by multiple connecting rods 24, the two turntables 23 rotate synchronously. The movable sleeve 25 in the annular groove on the outer wall of the connecting rod 24 moves together with the connecting rod 24. The blade 26 on the outer wall of the movable sleeve 25 crushes and cuts the falling sugarcane leaves under the action of centrifugal force. Only crushed material with the required particle size can pass through the mesh of the arc-shaped mesh plate 22 and enter the uniform material mechanism below, so as to realize the control of the crushed particle size of the sugarcane leaves.

[0036] As a technical optimization of this utility model, the right end of the L-shaped frame 2 is provided with an outlet, and the bottom end of the inner wall of the L-shaped frame 2 is fixedly connected with a guide block 18, which extends into the outlet and has an inclined structure at the top.

[0037] In this embodiment, the guide block 18 extends into the outlet and has a sloping upper end, which can reduce the accumulation of debris and ensure that the debris is smoothly discharged from the outlet and spread to the field.

[0038] As a technical optimization of this utility model, the bottom of the material box 1 is fixedly connected to a guide block with an inclined surface on the upper end.

[0039] In this embodiment: after the sugarcane leaves are put into the raw material box 1, the inclined structure can guide the sugarcane leaves to move towards the outlet at the lower end of the raw material box 1, so as to avoid the sugarcane leaves accumulating in the raw material box 1 and ensure smooth feeding.

[0040] As a technical optimization of this utility model, multiple fixing rods are fixedly connected to the outer walls of the two material tubes 16, and the other ends of the multiple fixing rods are fixedly connected to the inner wall of the L-shaped frame 2.

[0041] In this embodiment, the outer walls of both material tubes 16 are fixedly connected to the inner wall of the L-shaped frame 2 by multiple fixing rods. The fixing rods can stably support the material tubes 16 and prevent them from shifting when the atomizing nozzle 17 sprays reagents or when the equipment vibrates during operation, thus ensuring the stability of the reagent spraying position.

[0042] The working principle and usage process of this utility model are as follows: During use, the sugarcane leaves to be processed are stored in the raw material box 1. Then, the auxiliary feeding mechanism is activated, and the second drive motor 5 drives the rotating shaft 20 to rotate. Multiple turning plates 21 on the outer wall of the rotating shaft 20 rotate accordingly, turning and pushing the sugarcane leaves entering the L-shaped frame 2 downwards. The second sealing blocks 19 at both ends of the inner wall of the L-shaped frame 2 prevent the sugarcane leaves from leaking out from the gaps on both sides, while the second guide strip at its upper end further gathers the sugarcane leaves towards the center, ensuring that the sugarcane leaves enter the crushing mechanism below at a stable flow rate.

[0043] At the same time, the crushing mechanism starts to work, with the third drive motor 27 driving one of the turntables 23 to rotate. Since the two turntables 23 are fixedly connected by multiple connecting rods 24, the two turntables 23 rotate synchronously. The movable sleeve 25 in the annular groove on the outer wall of the connecting rod 24 moves together with the connecting rod 24. The blade 26 on the outer wall of the movable sleeve 25 crushes and cuts the falling sugarcane leaves under the action of centrifugal force. Only crushed material with the required particle size can pass through the mesh of the arc-shaped mesh plate 22 and enter the uniform material mechanism below, so as to realize the control of the crushed particle size of the sugarcane leaves.

[0044] The crushed material accumulates on the upper side of the leveling roller 4. Simultaneously, the first drive motor 6 drives the leveling roller 4 to rotate inside the L-shaped frame 2. The multiple leveling grooves of the leveling roller 4 receive the crushed material, and as the leveling roller 4 rotates at a constant speed, it pushes the crushed material downwards evenly. The first sealing blocks 3 at both ends of the inner wall of the L-shaped frame 2 are fitted with the outer wall of the leveling roller 4 to prevent the crushed material from leaking out from both sides. The first guide strip at its upper end guides the crushed material into the leveling groove. Under the continuous rotation of the leveling roller 4, the crushed material is evenly transported to the upper end of the guide block 18 at the bottom of the L-shaped frame 2. The guide block 18 guides the crushed material to slide to the right. In the above process, the leveling mechanism makes the crushed material fall evenly, avoiding local accumulation or scattering. When spraying reagents later, it can improve the uniformity of contact between the material and the reagent, preventing the degradation efficiency from being affected by insufficient reagents and avoiding waste caused by excessive reagents.

[0045] As the crushed material slides to the right along the guide block 18, the dual-liquid spraying mechanism is activated. The cellulase chamber 9 and the *Aminococcus globulus* suspension chamber 10, separated by the partition 8, store cellulase and *Aminococcus globulus* suspension, respectively. When the booster pump 11 is working, it draws cellulase from the cellulase chamber 9 through the first bend pipe 12, and simultaneously draws *Aminococcus globulus* suspension from the *Aminococcus globulus* suspension chamber 10 through the first straight pipe 14 connected to the outer wall of the first bend pipe 12. The two reagents enter the left-side feed pipe 16 through the outlet of the booster pump 11 and the second bend pipe 13, and enter the right-side feed pipe 16 through the second bend pipe 13 and the second straight pipe 15, respectively. Finally, they are sprayed synchronously through multiple atomizing nozzles 17 evenly distributed at the lower end of the two feed pipes 16, and evenly sprayed onto the surface of the crushed material. The sprayed crushed material is discharged from the outlet and spread in the field. This dual-liquid synchronous spraying design effectively shortens the processing flow, eliminates the need for multiple additional conveying and spraying components, and reduces the complexity of the equipment structure.
