[0002] Under the trend of green transformation and precision development in agriculture, the resource utilization of straw and the reduction and efficiency improvement of chemical fertilizers have become core needs for soil improvement. Currently, straw return to the field suffers from problems such as insufficient crushing, easy tangling, and loose binding with the soil, leading to potential risks such as crop competition for nutrients and uneven seedling emergence.

One end of the third rotating shaft 18 is connected to the output end of the gearbox 2 through a rotating belt.

[0031] In some specific embodiments, the transmission component includes: The first pipe 20 extends through the body 1 to the bottom of the body 1, and the bottom of the first pipe 20 is provided corresponding to the crushing roller shaft 5; The impeller 21 is disposed at the top of the first pipe 20; The second pipe 22 has one end connected to the output end of the throwing impeller 21, and the other end of the second pipe 22 extends to the side of the main body 1 away from the gearbox 2. Baffle 23 is disposed on the side of the main body 1 away from the gearbox 2, and the baffle 23 is disposed corresponding to the second pipe 22.

[0032] In some specific embodiments, the fertilization component includes: Storage box 24, the bottom of which is fixedly connected to the top of the main body 1, the top of the storage box 24 is provided with an opening, and a support groove 25 is provided at the center of the top of the storage box 24. The second pipe 22 is provided inside the support groove 25, and the inside of the storage box 24 is used to place fertilizer. Multiple flow tubes 26 are provided, and the multiple flow tubes 26 are respectively connected to multiple flow ports 3. The side walls of the multiple flow tubes 26 are fixedly connected to the bottom of the main body 1 through the connector 27. The outlet ends of the multiple flow tubes 26 are located between the third rotating shaft 18 and the crushing roller shaft 5.

[0033] In some specific embodiments, a rotating impeller 28 is provided inside each of the plurality of flow ports 3.

[0034] It should be understood that before operation, one end of the main body 1 is fixedly connected to the mounting end of the tractor, so that the input end of the gearbox 2 is connected to the output end of the tractor, forming a power transmission path. The power output by the tractor engine is regulated by the gearbox 2 in terms of speed and torque, and then transmitted to the second rotating shaft 9 of the crushing component and the third rotating shaft 18 of the rotary tillage component through the rotating belt, providing stable power to the core operating components; at the same time, the tractor's controller establishes an electrical connection with multiple key control components of the equipment, including the distance sensor 4, the first hydraulic cylinder 12, the second hydraulic cylinder 14 and the rotating impeller 28, to realize signal acquisition, command issuance and precise control.

[0035] Straw crushing and intelligent height adjustment are the primary steps in the operation. During operation, distance sensor 4 continuously monitors the vertical distance between the main body 1 and the ground, transmitting the data to the tractor controller. Based on preset crushing depth parameters and real-time monitoring data, the controller sends extension / retraction commands to the first cylinder 12: when the crushing depth needs to be increased, the extension / retraction end of the first cylinder 12 extends, pushing the roller 13 downwards within the sliding groove 10 of the second connecting rod 8, causing the second connecting rod 8 to rotate downwards around the first rotating shaft 7, thus bringing the crushing roller 5 closer to the ground; when the terrain is uneven or the crushing depth needs to be reduced, the extension / retraction end of the first cylinder 12 retracts, the roller 13 slides upwards, the second connecting rod 8 rotates upwards around the first rotating shaft 7, and the crushing roller 5 rises accordingly. During this process, the width of the roller 13 is greater than the width of the opening at the top of the sliding groove 10, ensuring that it does not disengage from the sliding groove 10 during adjustment and guaranteeing structural stability. Meanwhile, the second rotating shaft 9 drives the crushing roller shaft 5 to rotate at high speed under the power of the gearbox 2, which finely crushes the straw in the target land. The crushed particle size can be adapted to the needs of different crop straws by adjusting the rotation speed of the crushing roller shaft 5 (which is achieved by the speed regulation of the gearbox 2).

[0036] The crushed straw is directionally spread via a conveying assembly. The straw fragments, crushed by the crushing roller 5, are drawn into the conveying assembly through the first pipe 20 under the influence of their own kinetic energy and the negative pressure generated by the throwing impeller 21. The throwing impeller 21 rotates at high speed under power, generating a continuous airflow that transports the straw fragments along the first pipe 20 to the top, where they are then directionally conveyed through a connected second pipe 22 to the end of the main body 1 furthest from the tractor. The second pipe 22 is installed within a support groove 25 on the top of the storage box 24, ensuring structural compactness and preventing pipe displacement. After exiting from the second pipe 22, the straw fragments are evenly spread on the surface of the crushed area under the obstruction and guidance of the baffle 23, preparing for subsequent mixing with soil and fertilizer.

[0037] Precision fertilization is carried out simultaneously with straw spreading. The fertilizer pre-loaded inside the storage tank 24 flows towards the bottom inlet 3 under gravity. The tractor controller adjusts the rotation speed of the impeller 28 based on the operating speed and soil fertility detection data (which can be connected to an external soil sensor or preset parameters): the higher the speed, the greater the flow rate of fertilizer through the inlet 3; the lower the speed, the smaller the flow rate, thus achieving precise fertilization on demand. The fertilizer enters multiple flow pipes 26 through the inlet 3. The flow pipes 26 are fixed to the bottom of the main body 1 by connectors 27, and their outlets are precisely aligned with the area between the crushing roller shaft 5 and the third rotating shaft 18, allowing the fertilizer to fall directly into the junction of the straw fragments and the soil to be tilled, laying the foundation for subsequent mixing operations.

[0038] The rotary tillage mixing process achieves deep integration of soil, straw, and fertilizer. Driven by the gearbox 2, the third rotating shaft 18 rotates at high speed, causing multiple rotary tillage blades 19 on the sidewall to cut and break up the soil in the target area. The rotation trajectory of the rotary tillage blades 19 covers the fertilizer drop area and the straw spreading area, breaking up compacted soil while thoroughly mixing the pulverized straw fragments, precisely applied fertilizer, and topsoil to form a loose, fertile tillage layer. This promotes the decomposition of straw into soil organic matter, improves fertilizer utilization, and prevents nutrient loss.

[0039] Finally, soil moisture is optimized through the compaction components. The tractor controller sends extension / retraction commands to the second hydraulic cylinder 14 based on parameters such as soil moisture and tillage depth, adjusting the tilt angle of the third connecting rod 15, thereby changing the pressure of the compaction roller 16 on the ground surface. When the soil is too dry, the compaction pressure is reduced to prevent soil compaction; when the soil is too wet or to improve moisture retention, the compaction pressure is increased. The compaction roller 16, pulled by the tractor, rolls with the main body 1, moderately compacting the rotary-tilled soil, ensuring a tight bond between soil particles, straw, and fertilizer, reducing water evaporation, and creating a smooth surface, thus providing favorable conditions for subsequent sowing operations.

[0040] Throughout the entire operation, the components work together in the order of "crushing-spreading-fertilizing-rotary tillage-compacting" and are intelligently controlled by the tractor controller. This simplifies the traditional multi-process operation and ensures the accuracy and efficiency of soil improvement, adapting to the farming needs of different terrains and soil conditions.

[0041] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
