Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a tillage device for improving soil structure in low-lying areas. Background Technology

[0002] To address the issues of soil compaction, poor aeration, and inadequate drainage in low-lying areas, the deep tillage function of a subsoiler can be used to break up the plow pan, increase soil porosity, and improve the soil aggregate structure, aeration, and drainage capacity in low-lying areas by combining these methods with organic fertilizer application. This will help create a more suitable soil environment for crop growth in low-lying areas.

[0003] Subsoilers, when attached to intelligent agricultural power machinery, rely on their navigation and big data systems to automatically plan routes and control tillage depth, making subsoil operations more precise and labor-saving. Some existing subsoilers have a long, chopping roller at the rear, which crushes large clods of soil produced by the subsoiler, breaking up soil compaction and making soil particles finer and more uniform. The chopping roller also levels the subsoil surface, reducing excessive soil porosity and uneven terrain, creating better conditions for subsequent planting, irrigation, and other agricultural operations. Because the chopping roller is usually a single, long unit, it is more suitable for flat land. On uneven land, the roller will rise or fall with the terrain, resulting in uneven compaction, insufficient compaction in high areas, and excessive compaction in low areas, leaving furrows. Furthermore, when localized damage occurs, the entire roller needs to be repaired and replaced, leading to high costs. Summary of the Invention

[0024] The adjustment mechanism includes cylinder 21, telescopic bracket 23 and auxiliary components. Cylinder 21 is fixedly installed at the middle of the top of the mounting bracket 4.

The multiple connecting shafts 24 are fixedly connected to their respective connecting sliders 11.

[0025] The auxiliary components include an adjusting rod 25 and a lower pressure plate 29. The adjusting rod 25 is located on the side of the mounting bracket 4 away from the telescopic bracket 23. The bottom end of the connecting rod 22 away from the multiple adjusting seats 5 is fixedly connected to the adjusting rod 25. A guide rod 26 is slidably sleeved inside the adjusting rod 25. The guide rod 26 is fixedly installed on one side of the mounting bracket 4. Two transmission rods 28 are symmetrically fixedly installed on the side of the adjusting rod 25 near the cylinder 21. The lower pressure plate 29 passes through the interior of the multiple adjusting seats 5. Guide rods 30 are slidably sleeved at both ends of the lower pressure plate 29.

[0026] Both transmission rods 28 are fixedly fitted with reinforcing sliders 34, and both ends of the top of the mounting bracket 4 are provided with reinforcing grooves 35. The two reinforcing sliders 34 are respectively slidably set inside the two reinforcing grooves 35.

[0027] Multiple L-shaped fixing plates 19 are fixedly installed on both sides of multiple soil crushing rollers 7, and each L-shaped fixing plate 19 has a through hole 20 inside.

[0028] Working principle: When in use, the device is connected to the intelligent agricultural power machinery through the connecting frame 3. Then, the appropriate state of the soil crushing roller 7 is selected according to the terrain. If the land is uneven, the device can be used directly for deep loosening: the power machinery pulls the frame 1 to move, the frame 1 drives multiple deep loosening shovels 2 and multiple soil crushing rollers 7 to move synchronously. The multiple deep loosening shovels 2 carry out deep loosening of the soil, and the multiple soil crushing rollers 7 crush large soil clods and level the surface after deep loosening. During the rotation of multiple soil crushing rollers 7, the elastic mechanism above them moves accordingly. The movement process of one of the elastic mechanisms is as follows: when the soil crushing roller 7 is moved upward under force, it drives the rotating bracket 6 at the top of the soil crushing roller 7 to rotate accordingly. The rotating bracket 6 pushes the mounting rod 14 at the top to move upward. The spring 16 outside the mounting rod 14 is compressed by force. The top of the mounting rod 14 moves accordingly inside the groove 15. Under the action of the limiting pin 18 and the limiting ring 17, the mounting rod 14 is prevented from disengaging from the adjusting seat 5. When the terrain is relatively flat, cylinder 21 is activated, causing connecting rod 22 to move. Adjusting seat 5 and adjusting rod 25, connected to connecting rod 22, move synchronously. As adjusting seat 5 moves, under the action of telescopic bracket 23, the adjusting seats 5 on both sides cause their corresponding connecting sliders 11 to slide within the two connecting grooves 12. The adjusting seats 5 on both sides move closer to the adjusting seat 5 in the middle, thereby causing the soil-crushing rollers 7 on both sides to move closer to the soil-crushing roller 7 in the middle until they are in contact. Then, the two adjacent soil-crushing rollers 7 are rotated so that the L-shaped fixing pieces 19 on the side where the two soil-crushing rollers 7 are close to each other correspond to each other. Positioning pins or bolts are inserted into the through holes 20 in the corresponding two L-shaped fixing pieces 19 to fix any two L-shaped fixing pieces 19 in any given set. This allows for the fixing of two adjacent soil-crushing rollers 7. Multiple soil-crushing rollers 7 can be fixed using the same method, achieving synchronous rotation during subsequent rotations. This prevents friction between the rollers and avoids affecting their lifespan. The invention allows for the selection of separate soil-crushing rollers 7 or their integration into a single unit, depending on the terrain. Separate rollers 7 are suitable for uneven land, rising and falling with the terrain to ensure effective crushing and leveling of the land after deep tillage. Furthermore, partial damage eliminates the need for overall repair, reducing costs. A single integrated roller 7 is suitable for flat land. In addition, this device, when used in conjunction with intelligent agricultural power machinery, maximizes the operational efficiency of the deep tillage machine. During the process of cylinder 21 pulling the connecting rod 22, the adjusting rod 25 moves synchronously. The adjusting rod 25 slides along the guide rod 26 and drives the two transmission rods 28 on one side to move synchronously. During the movement of the two transmission rods 28, they respectively drive the two reinforcing sliders 34 to slide inside the two reinforcing grooves 35. The mutual cooperation between the two reinforcing sliders 34 and the two reinforcing grooves 35 can enhance the stability of the two transmission rods 28 when they move. One end of the two transmission rods 28 moves inside the two transmission grooves 33, and the lower pressure plate 29 is forced to move downward along the two guide rods 30, squeezing the two springs 31. As the lower pressure plate 29 moves downward, it acts on multiple rotating supports 6, so that the multiple rotating supports 6 are at the bottom and are in contact with multiple limiting plates 13. At this time, the multiple soil crushing rollers 7 can be set coaxially. The multiple soil crushing rollers 7 are in contact in a coaxial state, ensuring the working effect on the land when the multiple soil crushing rollers 7 are connected as a whole.

[0029] When the soil moisture content is too high or there are many large stones, tree roots and other debris, multiple soil-crushing rollers 7 are not suitable. They need to be lifted. When lifting, two cylinders 10 are activated. The telescopic shaft ends of the two cylinders 10 pull the two rotating arms 8 respectively. One end of the two rotating arms 8 rotates inside the two mounting seats 9 respectively, thereby lifting the entire mounting bracket 4 and moving the multiple soil-crushing rollers 7 away from the ground.
