Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to an adaptive compaction adjustment device for a strip tillage machine. Background Technology

[0002] The adaptive compaction adjustment device of the strip tillage machine is an intelligent agricultural machinery device that can automatically or manually adjust the pressure of the compaction roller according to the actual conditions of soil moisture, hardness and other conditions. This ensures that the soil compaction is appropriate during the tillage process, thereby improving seed germination rate and crop growth quality, while reducing soil erosion and achieving efficient and environmentally friendly agricultural farming.

[0003] Currently, soil compaction is performed using roller compactors. One acre of land is divided into multiple ridges. Due to the varying widths of the ridges, when the roller width is less than the ridge width, it cannot compact a single ridge in one pass, requiring two or more passes to complete the compaction. This not only results in low compaction efficiency but also causes uneven compaction pressure between the sides and the middle of the ridge. When the roller width is greater than the ridge width, it extends onto other ridges, affecting the subsequent compaction of those ridges. Currently, roller compactors are typically fixed using multiple structures, requiring significant work to replace, further impacting compaction efficiency. Therefore, an adaptive compaction adjustment device for strip tillage machines is proposed. Utility Model Content

[0023] Example 1, please refer to Figures 1 to 4 An adaptive compaction adjustment device for a strip tillage machine in this embodiment includes a drive base 1 and a drive wheel 2, and the outer wall of the drive base 1 is provided with an adjustment structure.

[0024] There are two drive wheels 2, which are installed on the left and right sides of the drive seat 1 respectively.

[0025] The adjustment structure includes a pressure roller drive hydraulic rod 3 fixedly installed on the bottom outer wall of the drive seat 1. An adjustment arm 4 is fixedly installed on the telescopic shaft of the pressure roller drive hydraulic rod 3. An adjustment rod 5 is fixedly installed on the front outer wall of the adjustment arm 4. Two adjustment rings 6 are slidably connected to the outer peripheral wall of the adjustment rod 5. A connecting rod 7 is fixedly installed on the outer peripheral wall of the adjustment ring 6. The connecting rod 7 is installed at an inclined angle. A mounting seat 8 is fixedly installed on the side of the connecting rod 7 away from the adjustment ring 6. A rotating bracket 9 is rotatably connected to the outer wall of the two mounting seats 8 on opposite sides. A hexagonal bracket 11 is slidably connected inside the rotating bracket 9. A hexagonal slot is opened on the side of the rotating bracket 9 away from the mounting seat 8. The hexagonal bracket 11 is slidably connected inside the hexagonal slot and is of a suitable size. The pressure roller 10 is located between the two mounting seats 8.

[0026] A pressing roller 10 is fixedly installed between two hexagonal clamps 11. Side rods 12 are fixedly installed on the outer walls of both sides of the adjusting arm 4. A guide plate 13 is fixedly installed on the side of the side rod 12 away from the adjusting arm 4. Four positioning slides 14 are fixedly installed on the bottom outer wall of the drive seat 1. The guide plate 13 is slidably connected between two adjacent positioning slides 14.

[0027] A bidirectional threaded rod 15 is rotatably mounted between two guide plates 13. A drive motor 16 is fixedly mounted on the outer right side of the right guide plate 13. The drive motor 16 passes through the inner wall of the right guide plate 13 and is fixedly connected to the right end of the bidirectional threaded rod 15. Two adjusting seats 17 are threadedly connected to the outer peripheral wall of the bidirectional threaded rod 15. The adjusting seats 17 are rectangular and have threaded holes inside. The bidirectional threaded rod 15 is threadedly connected to the inside of the threaded holes and is of a suitable size. The side of the adjusting seat 17 away from the drive seat 1 is fixedly connected to the outer peripheral wall of the adjusting ring 6.

[0028] In this embodiment, the guide plate 13 is slidably connected inside the positioning slide 14, which improves the stability of the guide plate 13 during sliding adjustment.

[0029] In this embodiment, the pressing roller 10 is connected to the rotating bracket 9 via a hexagonal locking rod 11. To replace the pressing roller 10, it is only necessary to disassemble and replace the hexagonal locking rod 11 and the rotating bracket 9.

[0032] The working principle of the above embodiment is:

[0033] When the press roller 10 cannot adapt to the width of the current ridge, the drive motor 16 starts and drives the bidirectional threaded rod 15 to rotate. At this time, the two adjusting seats 17 drive the two mounting seats 8 to move away from each other through the two adjusting rings 6 and the two connecting rods 7. When the hexagonal locking rod 11 separates from the rotating locking seat 9, the disassembly of the press roller 10 is completed. Then, the press roller 10 that matches the width of the ridge is moved between the two mounting seats 8. The drive motor 16 is started again and drives the two mounting seats 8 to move closer to each other through the adjusting seats 17, the two adjusting rings 6 and the two connecting rods 7. When the hexagonal locking rod 11 connects with the rotating locking seat 9, the installation of the press roller 10 is completed. At this time, the drive seat 1 is started to drive the drive wheel 2 to rotate and push the press roller 10 to move on the ridge and press it. When it is necessary to adjust the pressing pressure, the hydraulic rod 3 of the press roller drive extends and retracts and drives the adjusting arm 4 to move synchronously. At this time, the pressure adjustment of the press roller 10 is completed.
