Description

Technical Field

[0001] This application relates to the technical field of green manure return machines, and in particular to a green manure residue crushing and return machine. Background Technology

[0002] In the modern agricultural sustainable development system, green manure crops, as a high-quality source of organic fertilizer, can increase soil organic matter content, improve soil structure, and enhance soil fertility by returning their residues to the field. This plays a key role in ensuring crop yield and quality. Currently, the mainstream treatment methods for green manure residues include direct return to the field, composting, and incineration.

[0003] Regarding the aforementioned technologies, the inventors discovered that direct return to the field involves directly burying or covering harvested green manure residues on the soil surface without additional treatment. However, direct return results in large-volume green manure residues that decompose slowly, leading to delayed fertilizer release. Green manure residues also have high fiber content and an imbalanced carbon-nitrogen ratio, resulting in a long decomposition cycle under natural conditions, far exceeding the nutrient requirements of crop growth. Furthermore, it easily induces pests and diseases, affecting nutrient absorption. Composting, which transforms green manure residues into well-rotted organic fertilizer through microbial fermentation, improves fertilizer efficiency and safety, but is time-consuming and time-consuming due to limitations in site and time constraints. Incineration, which rapidly disposes of green manure residues through high-temperature combustion, shortens the processing time but poses significant environmental hazards. Utility Model Content

[0004] To overcome the shortcomings of existing methods, such as directly returning green manure to the field by simply burying or covering the soil surface after harvesting without additional treatment, which results in large-volume, slow decomposition of green manure residues, delayed fertilizer release, high fiber content, and an unbalanced carbon-nitrogen ratio, leading to a long decomposition cycle that far exceeds the nutrient requirements of crop growth, and also easily attracting pests and diseases and affecting nutrient absorption; composting, which transforms green manure residues into well-rotted organic fertilizer through microbial fermentation, can improve fertilizer efficiency and safety, but is time-consuming and time-consuming due to limitations in site and time constraints; and incineration, which quickly disposes of green manure residues through high-temperature combustion, can shorten processing time but is extremely harmful to the environment, this application provides a green manure residue crushing and returning machine.

[0005] The green manure residue crushing and returning machine provided in this application adopts the following technical solution: A green manure residue crushing and returning machine includes a crushing component, a slitting component, and a spraying component. The crushing component includes a crushing frame with two symmetrically rotating toothed rollers inside. A slitting component is located below the crushing frame, including a slitting frame horizontally positioned below the crushing frame, with its top end fixed to the bottom surface of the crushing frame. Two blades are vertically and symmetrically arranged inside the slitting frame, with multiple cutting blades staggered along the vertical direction on adjacent vertical end faces of the two blades. The spraying component includes a feeding box located below the slitting frame, with its top end fixed to the bottom surface of the slitting frame. A spraying rod is horizontally fixed inside the feeding box for spraying a composting agent.

[0006] By adopting the above technical solution, the crushing component uses two rotating toothed rollers within the crushing frame to initially crush the green manure residue, breaking down large pieces into medium-sized fragments for easier subsequent processing and pulverization. The slitting component uses two staggered blades and cutters within the slitting frame to further cut the crushed green manure residue into smaller fragments, thereby improving the decomposition efficiency of organic matter and the soil improvement effect. The feeding box and spraying rod in the spraying component are used to deliver the fragments of green manure residue into the soil and spray an appropriate amount of composting agent to promote the rapid decomposition of green manure residue and the release of nutrients, thereby improving soil fertility and crop yield. First, the rotating toothed rollers in the crushing component crush the green manure residue into medium-sized pieces, then the blades and cutters in the slitting component further cut it into smaller fragments, and finally the fragments of green manure residue fall into the field through the feeding box of the spraying component and are sprayed with composting agent by the spraying rod, promoting the rapid decomposition of green manure residue and effectively improving the soil.

[0007] Optionally, multiple fixed cutting teeth are uniformly fixed laterally on the symmetrical vertical end faces of the inner two sides of the crushing frame, and the multiple fixed cutting teeth are staggered with the cutting teeth on the adjacent rotating cutting roller.

[0008] By adopting the above technical solution, multiple fixed cutting teeth are uniformly fixed laterally on the symmetrical vertical end faces on both sides inside the crushing frame. These fixed cutting teeth play a role in cutting and fixing the material during the crushing process, ensuring that the material can be in stable contact with the rotating cutting tooth roller. The cutting teeth on the rotating cutting tooth roller rotate and interact with the fixed cutting teeth, further crushing and mixing the material, making it more uniform and fine. Inside the crushing frame, the material is initially fixed by the fixed cutting teeth under the combined action of the fixed cutting teeth and the rotating cutting tooth roller. Then, under the rotation of the rotating cutting tooth roller, the material is repeatedly cut and mixed between the interlaced cutting teeth, ultimately achieving a fine and uniform crushing effect.

[0009] Optionally, both ends of the crushing frame are horizontally fixed with rotating motors, and the output ends of the rotating motors are fixed to the ends of the two rotating toothed rollers.

[0010] By adopting the above technical solution, the horizontal fixing at both ends of the crushing frame ensures stable support for the rotating toothed rollers, guaranteeing its structural integrity during the crushing process. A rotating motor serves as the power source, driving the rotating toothed rollers at both ends to rotate, thereby achieving material cutting and crushing. Each rotating toothed roller is connected to its corresponding rotating motor via a fixed connection at its end, ensuring effective power transmission. When the rotating motor starts and drives the rotating toothed rollers to rotate, the cutting teeth knead and cut the material within the crushing frame. As the cutting teeth continuously rotate, the material is continuously crushed and discharged through the gaps between the cutting teeth, achieving efficient material processing.

[0011] Optionally, both ends of the slitting frame are fixed with pull bars, which are used for assembly with the drive mechanism.

[0012] By adopting the above technical solution, the slitting frame is used to fix and position the materials or products that need to be slitting. The pull strips fixed at both ends play a role in fixing and adjusting the position of the slitting frame, so that the slitting frame can be more easily and accurately assembled with the driving machine, thereby ensuring the accuracy and stability of the slitting operation.

[0013] Optionally, rods are horizontally slidably inserted on both vertical end faces of the slitting frame, and the ends of the rods are fixed to the blade plate. A top block is vertically fixed to the middle of the outer side of the rod, and a spring is horizontally sleeved on the outside of the rod, with the two ends of the spring fixed to the outer wall of the slitting frame and the rod respectively.

[0014] By employing the above technical solution, the slitting frame is used to fix and guide the blade for precise cutting of cardboard or other sheet materials. Horizontally sliding rods on both vertical end faces provide sliding guidance for the blade, ensuring its linear movement. The rods are fixed to the blade, allowing it to slide horizontally along with the rods. A vertically fixed and outwardly extending top block on the outer center of the rod contacts and presses against the inner wall of the slitting frame, serving as a limit and guide to prevent blade deviation. An externally fitted spring ensures the rods have a certain elastic restoring force during operation, allowing the blade to return to its initial position after each cut, ensuring cutting accuracy and repeatability. Driven by the spring, the blade slides horizontally along the guide of the rods and top block, cutting. After cutting, the blade returns to its initial position under the action of the spring, ready for the next cut.

[0015] Optionally, a pressing motor is fixed on both vertical end faces of the cutting frame, and a pressing block is fixed on the output end of the pressing motor, and the pressing block is pressed against the top block on the rod frame.

[0016] By adopting the above technical solution, pressure motors are fixed on both vertical ends of the slitting frame. Their function is to drive the pressure blocks to move along the length of the slitting frame. The pressure blocks are set to press against the top blocks on the frame, clamping and positioning the two ends of the material during the slitting process, ensuring the material remains in a fixed position during slitting and improving slitting accuracy and efficiency. When the material passes through the slitting frame, the pressure motors start, and their output drives the pressure blocks to move towards both ends of the material until the pressure blocks contact the top blocks and apply pressure, thereby clamping the material. In this way, regardless of changes in the length of the material, it can be stably clamped, preventing displacement during slitting and ensuring slitting quality and efficiency.

[0017] Optionally, rollers are rotatably connected to both ends of the outer side of the feeding frame box.

[0018] By adopting the above technical solution, the main function of the material handling frame is to transport materials on the production line. The rollers at both ends, connected by a rotating mechanism, can easily roll on tracks or the ground, reducing friction during movement and making material handling smoother and faster. Specifically, the rollers can easily turn when encountering obstacles, thereby improving the flexibility and efficiency of material transportation.

[0019] Optionally, a liquid storage cylinder is vertically connected and fixed to one end of the spray bar, and a high-pressure water pump is connected and fixed to the water pipe of the spray bar.

[0020] By adopting the above technical solution, the storage tank is used to store the composting agent, ensuring the supply of composting agent required for field spraying; the spraying rod is responsible for drawing liquid from the storage tank and transporting it to the spraying point through the water pipe on it. At the same time, one end of the spraying rod is vertically connected to and fixed to the storage tank, ensuring that the liquid in the storage tank can be smoothly transported to the spraying rod; the high-pressure water pump is installed on the water pipe of the spraying rod to pressurize and transport the liquid stored in the storage tank, so that it can be sprayed out in a high-pressure form, thereby improving the spraying effect and cleaning efficiency.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. Through a multi-stage crushing and directional composting design, the decomposition and nutrient release of green manure residues are significantly accelerated. Two-stage precision crushing increases the contact area for composting. The first stage uses rotating toothed rollers and fixed teeth to alternately squeeze and cut the green manure residues, compressing and cutting them into long segments, thus destroying the fibrous structure. The second stage uses a pressure motor to drive the blades to move laterally, further cutting the long segments of green manure into shorter segments. This results in a smaller residue volume compared to direct return to the field, and a larger specific surface area compared to simple crushing and return. The improved contact efficiency between the composting agent and the residues accelerates microbial decomposition, shortens the natural decomposition cycle, and perfectly matches the crop growth cycle. Directional spraying of the composting agent drives it to be evenly sprayed from the spray bar. The functional microorganisms in the composting agent can quickly adjust the carbon-nitrogen ratio of the residues, accelerate the degradation of cellulose and lignin, and precisely match the fertilizer release time with the crop's nutrient requirement period, improving early crop growth and reducing lodging rates later. 2. By combining physical crushing and biological control, the potential risks of returning green manure to the field are eliminated at the source. Crushing destroys the habitat of pests and diseases, significantly reducing their population. During the two-stage crushing process, pathogens and insect eggs in the green manure residue are mechanically squeezed and cut, which, combined with the antagonistic effect of functional microorganisms in the composting agent, reduces the population of soil pests and diseases compared to direct return to the field. No additional soil fungicide is needed, reducing pesticide use. The operation can be carried out on-site in the field, without the need for composting sites or transportation equipment. The green manure can be directly moved and operated in the field. After harvesting, the green manure is crushed, sprayed with composting agent, and returned to the field immediately, without the need for a special composting site, avoiding the transportation of residues and improving processing efficiency.

[0024] The present application will be further described in detail below with reference to the accompanying drawings.

[0025] This application discloses a green manure residue crushing and returning machine for use in the field. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 A green manure residue crushing and returning machine includes a crushing component 1, a slitting component 2, and a spraying component 3. The crushing component 1 includes a crushing frame 11 with two symmetrically rotating toothed rollers 13 inside. The slitting component 2 is located below the crushing frame 11 and includes a slitting frame 21. The slitting frame 21 is horizontally located below the crushing frame 11, and its top end is connected to and fixed to the bottom surface of the crushing frame 11. Two blades 23 are vertically symmetrically arranged inside the slitting frame 21, and multiple cutting blades are staggered along the vertical direction on the adjacent vertical end faces of the two blades 23. The spraying component 3 includes a feeding frame box 31 located below the slitting frame 21, and its top end is fixed to the bottom surface of the slitting frame 21. A spraying rod 32 is horizontally fixed inside the feeding frame box 31 and is used to spray a composting agent.

[0026] By adopting the above technical solution, the crushing component 1 uses two rotating toothed rollers 13 within the crushing frame 11 to initially crush the green manure residue, breaking down large pieces into medium-sized pieces for easier subsequent processing and pulverization. The slitting component 2 uses two staggered blades 23 and cutters within the slitting frame 21 to further cut the crushed green manure residue into smaller fragments, thereby improving the decomposition efficiency of organic matter and the soil improvement effect. The feeding box 31 and spraying rod 32 in the spraying component 3 are used to deliver the fragments of green manure residue into the soil and spray an appropriate amount of composting agent to promote the rapid decomposition of green manure residue and the release of nutrients, thereby improving soil fertility and crop yield. First, the rotating toothed roller 13 in the crushing component 1 crushes the green manure residue into medium-sized pieces. Then, it is further cut into small fragments by the blade 23 and cutter in the slitting component 2. Finally, the fragments of the green manure residue fall into the field through the discharge box 31 of the spraying component 3 and are sprayed with composting agent by the spraying rod 32, which promotes the rapid decomposition of the green manure residue and effectively improves the soil.

[0027] Reference Figure 3Multiple fixed cutting teeth 12 are evenly fixed laterally on the symmetrical vertical end faces of the crushing frame 11, and these fixed cutting teeth 12 are staggered with the cutting teeth on the adjacent rotating cutting roller 13. These fixed cutting teeth 12 cut and fix the material during the crushing process, ensuring that the material can maintain stable contact with the rotating cutting roller. The cutting teeth on the rotating cutting roller 13 rotate and interact with the fixed cutting teeth 12, further crushing and mixing the material, resulting in a more uniform and finely crushed material. Inside the crushing frame 11, the material is initially fixed by the fixed cutting teeth 12, and then, under the rotation of the rotating cutting roller 13, the material is repeatedly cut and mixed between the staggered cutting teeth, ultimately achieving a fine and uniform crushing effect. Both ends of the crushing frame 11 are horizontally fixed with rotating motors 14, and the output ends of the rotating motors 14 are fixed to the ends of two rotating toothed rollers 13. The horizontal fixing of both ends of the crushing frame 11 ensures stable support for the rotating toothed rollers 13, guaranteeing its structural integrity during the crushing process. The rotating motors 14 serve as the power source, driving the rotating toothed rollers 13 to rotate, thereby achieving material cutting and crushing. Each rotating toothed roller 13 is connected to its corresponding rotating motor 14 via a fixed connection at its end, ensuring effective power transmission. When the rotating motor 14 starts and drives the rotating toothed rollers 13 to rotate, the cutting teeth knead and cut the material within the crushing frame 11. As the cutting teeth rotate continuously, the material is continuously crushed and discharged through the gaps between the cutting teeth, achieving efficient material processing.

[0028] Reference Figure 4The slitting frame 21 has pull bars 22 fixed at both ends, which are used for assembly with the drive mechanism. The slitting frame 21 is used to fix and position the materials or products to be slitted. The pull bars 22 fixed at both ends assist in fixing and adjusting the position of the slitting frame, making it easier to assemble the slitting frame with the drive mechanism accurately, thereby ensuring the accuracy and stability of the slitting operation. Rods 24 are horizontally slidably inserted into the vertical end faces on both sides of the slitting frame 21, and the ends of the rods 24 are fixed to the blade plate 23. A top block 25 is vertically fixed to the middle of the outer side of the rods 24, and a spring 26 is horizontally sleeved on the outside of the rods 24. The two ends of the spring 26 are respectively fixed to the outer wall of the slitting frame 21 and the rods 24. The sliding frame 21 is used to fix and guide the blade plate 23 to accurately cut cardboard or other sheet materials. The horizontally slidable rods 24 on the vertical end faces on both sides provide sliding guidance for the blade plate 23, ensuring its linear movement. The rod frame 24 is fixed to the blade plate 23, allowing the blade plate 23 to slide horizontally together with the rod frame 24. A vertically fixed and outwardly extending top block 25 on the outer center of the rod frame 24 contacts and presses against the inner wall of the slitting frame 21, serving as a limit and guide to prevent the blade plate 23 from shifting. An externally fitted spring 26 ensures that the rod frame 24 has a certain elastic restoring force during operation, allowing the blade plate 23 to return to its initial position after each cut, ensuring cutting accuracy and repeatability. Driven, the blade plate 23 slides horizontally along the guide of the rod frame 24 and the top block 25, cutting. After cutting, the blade plate 23 returns to its initial position under the action of the spring 26, ready for the next cut. A pressure motor 27 is fixed to both vertical end faces of the slitting frame 21, and a pressure block 28 is fixed to the output end of the pressure motor 27, with the pressure block 28 pressing against the top block 25 on the rod frame 24. A pressure motor 27 is fixed to each of the two vertical ends of the slitting frame 21. Its function is to drive the pressure block 28 to move along the length of the slitting frame 21. The pressure block 28 is set to press against the top block 25 on the rod 24, used to clamp and position the two ends of the material during the slitting process, ensuring the material is fixed in position during slitting and improving slitting accuracy and efficiency. When the material passes through the slitting frame 21, the pressure motor 27 starts, and its output drives the pressure block 28 to move towards both ends of the material until the pressure block 28 contacts the top block 25 and applies pressure, thereby clamping the material. In this way, regardless of the change in the length of the material, it can be stably clamped, preventing displacement during the slitting process and ensuring slitting quality and efficiency.

[0029] Reference Figure 5The material unloading box 31 has rollers 35 rotatably connected to both ends of its outer side. The main function of the material unloading box 31 is to transport materials on the production line. The rollers 35 at both ends, through rotatable connection, can easily roll on tracks or the ground, reducing friction during movement and making handling smoother and faster. Specifically, the rollers 35 can easily turn when encountering obstacles, thereby improving the flexibility and efficiency of material transportation. A liquid storage cylinder 33 is vertically connected and fixed to one end of the spray bar 32, and a high-pressure water pump 34 is connected and fixed to the water pipe of the spray bar 32. The storage tank 33 is used to store the composting agent, ensuring the supply of composting agent required for field spraying; the spray rod 32 is responsible for drawing liquid from the storage tank 33 and transporting it to the spraying point through the water pipe on it. At the same time, one end of the spray rod 32 is vertically connected to and fixed to the storage tank 33, ensuring that the liquid in the storage tank 33 can be smoothly transported to the spray rod 32; the high-pressure water pump 34 is installed on the water pipe of the spray rod 32 to pressurize and transport the liquid stored in the storage tank 33, so that it can be sprayed out in a high-pressure form, thereby improving the spraying effect and cleaning efficiency.

[0030] The implementation principle of the green manure residue crushing and returning machine in this application embodiment is as follows: First, when returning crushed green manure to the field, the green manure is added from the top of the crushing frame 11 of the crushing component 1. The rotating motor 14 is started to drive the rotating toothed roller 13 to rotate in the crushing frame 11. The teeth on the rotating toothed roller 13 and the fixed teeth 12 on the inner wall of the crushing frame 11 are interleaved to squeeze, cut and flatten the green manure, cutting the green manure into long segments. Then, the long green manure enters the cutting frame 21 of the cutting component 2. In order to further cut the green manure and facilitate its return to the field and accelerate decomposition, the pressure motor 27 on the outside of the cutting frame 21 is started to drive the pressure block 28 to rotate. The rotating pressure block 28 presses against the top block 25 on the outside of the rod frame 24, pushing the rod frame 24 to slide laterally in the cutting frame 21, which drives the adjacent cutters of the two blades 23 to further cut the long green manure into short segments. Finally, the small pieces of green manure fall into the feeding box 31. The high-pressure water pump 34 on the water pipe of the spray rod 32 is started, which drives the composting agent in the storage tank 33 into the spray rod 32. After the composting agent is sprayed from the spray rod 32 toward the falling small pieces of green manure, the small pieces of green manure sprayed with composting agent fall into the field.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
