Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery and equipment technology, specifically to a cotton stalk strip tillage machine. Background Technology
[0002] Strip tillage is a method of intermittent, localized cultivation of the soil surface. The tilled strips loosen the soil, creating suitable seedbed conditions for crop sowing and growth, while untilled areas retain crop residue as cover. Strip tillage is a type of conservation tillage used to reduce soil erosion and improve soil moisture retention.
[0003] In the process of implementing strip tillage in the field, the entire field is not tilled. Instead, the tilling components of a tillage machine operate within a certain spacing and width. For example, the machine's disc plow blades or chisel-shaped shovels create loose strips of soil at set intervals. The soil between the strips can maintain its relatively original shape, which helps to improve soil aeration, permeability, and water retention while reducing soil erosion and water evaporation.
[0004] However, when implementing strip tillage techniques in cotton fields, the need to maintain the upright stalks of cotton plants within the strips is often overlooked. Tillage machines typically span multiple strips, with the tillage components rotary tilling the soil between the previous season's strips. This can easily cause the machine frame to crush the cotton stalks within the strips. As a result, the crushed and lodged cotton stalks not only fail to protect the new strips but also increase the need to handle the lodged stalks, thus impacting tillage efficiency. Summary of the Invention
[0005] The purpose of this invention is to provide a land preparation device for the implementation of strip tillage technology in the field, which is used to prepare the land between strip tillage strips, avoid crushing and lodging the upright stalks of plants, and improve the land preparation efficiency.
[0006] To achieve the above objectives, the present invention adopts the following solution:
[0007] A cotton stalk strip tillage machine includes a frame, a transmission component, a rotary tillage assembly, and a tillage component for passing between strip tillage strips;
[0008] The frame is equipped with a connecting frame for connecting traction equipment, and a tillage channel is formed between adjacent tillage strips. The lateral width of the frame is smaller than the width of the tillage channel.
[0009] The transmission component is mounted on the frame. The transmission component includes a transmission box, a transmission shaft, and a chain drive mechanism for transmitting power to the rotary tillage assembly. The input end of the transmission box is connected to the power output end of the traction device, and the output end of the transmission box is connected to the chain drive mechanism through the transmission shaft.
[0010] The rotary tillage assembly is mounted on the frame and spans across the top of the tillage channel;
[0011] The tillage component is located behind the rotary tillage assembly. The tillage component includes a roller and a mounting frame. The roller is connected to the frame via the mounting frame.
[0012] Preferably, the rotary tillage assembly includes a primary rotary tillage unit and a secondary rotary tillage unit arranged sequentially along the traveling direction of the frame. The transmission box includes a primary reducer for transmitting power to the rotary tillage unit and a secondary reducer for transmitting power to the secondary rotary tillage unit. The input end of the primary reducer is connected to the power output end of the traction device. The primary reducer is provided with a first output end for connecting to the chain drive mechanism and a second output end for connecting to the secondary reducer.
[0013] Preferably, the primary rotary tillage unit includes a rotating shaft and rotary tillage blade assemblies, with multiple rotary tillage blade assemblies arranged linearly along the axial direction of the rotating shaft.
[0014] Preferably, the rotary tiller assembly includes a blade holder and blades, with the blade holder connected to the side wall of the rotating shaft and the blades mounted on the blade holder by fasteners.
[0015] Preferably, adjacent blades are installed with their backs to each other.
[0016] Preferably, a protective cover is provided on the outside of the chain drive mechanism, and the protective cover is installed on the side wall of the frame.
[0017] Preferably, the horizontal width of the frame is 1.2m-1.4m.
[0018] Compared with existing technologies, the cotton stalk strip tillage machine provided by this utility model has the following substantial features and advancements: By setting the lateral width of the frame to be smaller than the width of the tillage channel, the machine can smoothly pass between adjacent strip tillage zones, effectively avoiding crushing of the cotton stalks on the strip tillage zones. This enables tillage between strip tillage zones, improving tillage efficiency. After strip tillage, the cotton plants on the strip tillage zones maintain an upright stalk position, playing a natural role in windbreak and soil stabilization. Furthermore, the cotton stalks provide some shade in the field, reducing the area of the soil surface directly exposed to solar radiation and optimizing the sowing conditions for the next crop. When the cotton stalks naturally decompose, the nutrients stored within them are returned to the soil, increasing the organic matter content in the soil. In addition, the transmission components are rationally arranged; after receiving power from the traction equipment, the transmission box accurately transmits the power to the rotary tillage components via the transmission shaft and chain transmission mechanism. This transmission method ensures the stability of power transmission, reduces power loss, and enables the rotary tillage components to operate stably and efficiently, guaranteeing the quality and efficiency of strip tillage operations. The rear tillage components further optimize the soil surface condition, and the compaction wheel is connected to the frame through the mounting bracket to compact the soil after rotary tillage, resulting in suitable soil compaction and improving the overall tillage effect.

[0025] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0026] like Figures 1-5 As shown in the embodiment of this utility model, a cotton stalk strip tillage machine is proposed. It aims to perform land preparation between strip tillage strips during the implementation of strip tillage technology in the field, so as to avoid crushing and lodging of the upright stalks of the plants and improve the land preparation efficiency.
[0027] The cotton stalk strip tillage machine proposed in this embodiment of the invention allows the machine to pass smoothly between adjacent strip tillage zones by setting the lateral width of the frame to be smaller than the width of the tillage channel. This effectively avoids crushing the cotton stalks on the strip tillage zones, enabling tillage between the strip tillage zones and improving tillage efficiency. After strip tillage, the cotton plants on the strip tillage zones maintain an upright stalk position, playing a natural role in windbreak and soil stabilization. Furthermore, the cotton stalks provide some shade in the field, reducing the area of the soil surface directly exposed to solar radiation and optimizing the sowing conditions for the next season's crops. When the cotton stalks decompose naturally, the nutrients stored within them are returned to the soil, increasing the organic matter content in the soil.
[0028] like Figure 1 Combination Figure 2 As shown, a cotton stalk strip tillage machine includes a frame 1 for passing between strip tillage strips, a transmission component 2, a rotary tillage assembly 3, and a tillage component 4. A connecting frame 5 for connecting a traction device is provided on the frame 1. A tillage channel is formed between adjacent strip tillage strips. The lateral width of the frame 1 is smaller than the width of the tillage channel.
[0029] like Figure 2 As shown, the transmission component 2 is mounted on the frame 1. The transmission component 2 includes a transmission box, a transmission shaft 23, and a chain drive mechanism 24 for transmitting power to the rotary tiller assembly 3. The input end of the transmission box is connected to the power output end of the traction device. The output end of the transmission box is connected to the chain drive mechanism 24 via the transmission shaft 23.
[0030] like Figure 1 Combination Figure 2 As shown, a protective cover 25 is provided on the outside of the chain drive mechanism 24. The protective cover 25 is installed on the side wall of the frame 1. The protective cover 25 is used to prevent foreign objects such as cotton leaves, dust, and small stones from entering the chain drive mechanism 24, and to avoid malfunctions such as jamming, accelerated wear, or even breakage between the chain and sprocket due to foreign objects.
[0031] like Figure 2 Combination Figure 4As shown, the rotary tillage assembly 3 is mounted on the frame 1 and spans across the tillage channel. The rotary tillage assembly 3 includes a primary rotary tillage unit 31 and a secondary rotary tillage unit 32 arranged sequentially along the travel direction of the frame 1. The transmission box includes a primary reducer 21 for transmitting power to the rotary tillage unit 31 and a secondary reducer 22 for transmitting power to the secondary rotary tillage unit 32. The input end of the primary reducer 21 is connected to the power output end of the traction device. The primary reducer 21 is provided with a first output end for connecting to the chain drive mechanism 24 and a second output end for connecting to the secondary reducer 22.
[0032] The system employs a structure with a primary rotary tillage unit 31 and a secondary rotary tillage unit 32 arranged sequentially, enabling step-by-step, refined soil treatment. The primary rotary tillage unit 31 first breaks up and loosens the soil, breaking up larger clods and compacted layers, creating better conditions for the operation of the secondary rotary tillage unit 32. For example, the primary rotary tillage unit 31 can break larger clods into fragments with a diameter of 5cm-10cm, which the secondary rotary tillage unit 32 can further refine to 2cm-5cm, making the soil texture more uniform and delicate, which is more conducive to the germination of cotton or chili seeds and root growth and development. Compared with equipment with a single rotary tillage unit, this improves the seed germination rate.
[0033] Different levels of rotary tillage units can have their parameters adjusted according to actual soil conditions and tillage requirements. For example, in areas with relatively compacted soil, the rotation speed of the first-level rotary tillage unit 31 can be appropriately reduced and its torque increased to better break up hard soil layers; while the rotation speed of the second-level rotary tillage unit 32 can be increased accordingly to achieve fine leveling and mixing of the soil, thereby improving the equipment's adaptability to different soil types and the controllability of tillage quality.
[0034] In addition, precise power distribution is achieved by setting a primary reducer 21 and a secondary reducer 22 to transmit power to the primary rotary tillage unit 31 and the secondary rotary tillage unit 32, respectively. The primary reducer 21 is directly connected to the traction equipment and can effectively receive and regulate the initial power of the power source, ensuring that the primary rotary tillage unit 31 receives a stable and appropriate power input, avoiding the impact on the rotary tillage effect or causing equipment failure due to excessive or insufficient power. For example, when encountering soil with high resistance, the primary reducer 21 can automatically adjust the transmission ratio to increase the torque output of the primary rotary tillage unit 31, ensuring its normal operation.
[0035] like Figure 3As shown, the land preparation component 4 is positioned behind the rotary tillage assembly 3. The land preparation component 4 includes a roller 41 and a mounting frame 42, with the roller 41 connected to the frame 1 via the mounting frame 42. During operation, the roller 41 rolls and flattens the soil surface as the frame 1 moves, eliminating any clods or furrows that may remain after rotary tillage, resulting in a smoother and more uniform soil surface and creating favorable conditions for subsequent sowing operations.
[0036] Because the compaction wheel 41 is tightly connected to the frame 1 and its position is relatively fixed, it ensures a high degree of consistency and stability in the compaction effect and flatness of the land after each operation during multiple strip tillage operations. To achieve different compaction effects, an adjustment rod can be installed between the mounting frame 42 and the compaction wheel 41. The adjustment rod is used to adjust the height of the compaction wheel 41 relative to the ground.
[0037] like Figure 4 As shown, the primary rotary tillage unit 31 includes a rotating shaft 311 and rotary tillage blade assemblies, with multiple blade assemblies arranged linearly along the axial direction of the rotating shaft 311. This linear arrangement of the blade assemblies increases the contact points and working area with the soil. During rotary tillage, each blade assembly sequentially applies cutting, crushing, and turning forces to the soil, causing multi-directional disturbance. This multi-directional action more effectively breaks down the compacted soil structure, breaking larger clods into finer particles.
[0038] For example, such as Figure 4 As shown, the four rotary tillage blade assemblies are arranged linearly along the axial direction of the rotating shaft 311. When the shaft 311 rotates, a continuous rotary tillage force field is formed, making the forces acting on the soil during tillage more stable and persistent, and enabling deeper soil loosening. The number of rotary tillage blade assemblies can be selected appropriately according to actual needs, preferably 4-8.
[0039] like Figure 5 As shown, the rotary tiller assembly includes a blade holder 312 and blades 313. The blade holder 312 is connected to the side wall of the rotating shaft 311. The blades 313 are mounted on the blade holder 312 using fasteners. This design, where the blades 313 are mounted on the blade holder 312 using fasteners, greatly facilitates the replacement and maintenance of the blades 313, and makes the adjustment of the angle and position of the blades 313 relatively easy. The installation angle of the blades 313 can be flexibly adjusted according to different soil types, cotton planting requirements, and operating stages.
[0040] For example, in areas with relatively loose soil, the angle of blade 313 can be increased to improve the rotary tillage depth and soil turning effect; while in areas with harder soil or where shallow tillage is required, the angle of blade 313 can be reduced to decrease operating resistance and reduce damage to the underlying soil structure.
[0041] like Figure 5 As shown, adjacent blades 313 are installed with their backs to each other. This arrangement results in more even and multidirectional soil stress during rotary tillage. When the shaft 311 rotates, the back-to-back blades 313 cut the soil in opposite directions, generating mutual pulling and squeezing forces in the horizontal direction, which can more effectively break up larger soil clods. In addition, the back-to-back blades 313 mutually restrain the soil throwing and accumulation during tillage. Soil thrown up by one side of the blades 313 is partially blocked by the adjacent back-to-back blades 313 and redistributed evenly, preventing excessive soil accumulation on one side to form high ridges or deep furrows, thus effectively improving the surface smoothness.
[0042] When using the cotton stalk strip tillage machine proposed in this embodiment, the lateral width of the frame 1 is typically set to 1.2m-1.4m. The position of the strip tillage strips is planned according to the cotton planting row spacing and plant distribution. The spacing between adjacent strip tillage strips is determined to ensure that the frame 1 can pass smoothly through the tillage channel between the strip tillage strips, while avoiding unnecessary damage to the cotton stalks.
[0043] Securely connect the connecting frame 5 to the tractor's three-point suspension system, and adjust the height and angle of the suspension system. As the tractor moves forward, the primary rotary tillage unit 31 begins its work, initially breaking up and loosening the soil. The primary rotary tillage unit 31 breaks up larger clods and initially turns over the topsoil. The soil treated by the primary rotary tillage unit 31 then enters the working range of the secondary rotary tillage unit 32. Under the coordinated power transmission of the primary reducer 21 and the secondary reducer 22, the secondary rotary tillage unit 32 further refines the soil particles, making the soil texture more uniform and meeting the rotary tillage standards required for planting.
[0044] After the rotary tillage assembly 3 completes the soil treatment, the rear tillage assembly 4 begins its work. The compaction roller 41 rolls on the tilled soil via the mounting frame 42 as the frame 1 moves, moderately compacting the soil. The compaction roller 41 can adjust the soil compaction, reduce soil porosity, prevent excessive evaporation of soil moisture, and provide a suitable soil environment for seed implantation and germination.
[0045] After strip tillage, the cotton plants in the strips are kept upright, which plays a natural role in windbreak and soil stabilization. In addition, the upright cotton stalks provide some shade in the field, reducing the area of the soil surface directly exposed to solar radiation and optimizing the sowing conditions for the next crop.
[0046] This utility model is not limited to the specific technical solutions described in the above embodiments. Besides the above embodiments, this utility model may have other implementation methods. For those skilled in the art, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
