Description

Technical Field

[0001] This application relates to the field of agricultural tillage machinery technology, and in particular to a ditching device with drag reduction function. Background Technology

[0002] In agricultural production, land cultivation is a fundamental step to ensure the normal growth of crops. The moldboard plow, a historically significant tillage tool, works by deeply penetrating the soil, loosening it, and providing a favorable growing environment for crops. Driven by power equipment such as tractors, the moldboard plow can perform continuous tillage in farmland. However, with the continuous development of modern agricultural technology, the traditional moldboard plow can no longer fully meet the needs of modern agricultural production. On the one hand, modern agriculture places greater emphasis on environmental protection and sustainable development, requiring tillage tools to reduce soil resistance, lower energy consumption, and improve soil removal rates and operational efficiency.

[0003] To address the aforementioned issues, researchers have made continuous improvements and innovations to moldboard plows in recent years. For example, they have optimized tillage depth by changing the shape and angle of the plow head; and improved the durability and operational efficiency of the plow by adopting new materials and manufacturing processes. Nevertheless, existing moldboard plow devices still have some shortcomings. For instance, they generate significant energy consumption and resistance during tillage, which does not meet the requirements of environmental protection and sustainable development. Summary of the Invention

[0020] To address the aforementioned issues, this application provides a ditching device with drag reduction function, which can effectively vibrate the plow back and forth, reduce the resistance of plowing, reduce energy consumption, and effectively improve the efficiency of plowing.

[0021] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0022] Figure 1 This is a schematic diagram of the structure of a trenching device with drag reduction function shown in the embodiments of this application.

[0023] See Figure 1 The trenching device with drag reduction function shown in Embodiment 1 of this application includes a plow frame 1, a support beam 2, a connecting structure 3, a plow shovel 4, a shaping plow 5, and a drive device 6. The plow frame 1 is connected to a power device for dragging. The support beam 2 is provided on the plow frame 1. The plow shovel 4 is installed on the support beam 2 through the connecting structure 3. A row of plow shovels 4 is installed on the support beam 2 according to the tillage conditions. The plow shovel 4 can rotate back and forth in a limited manner and is driven by the drive device 6. The drive device 6 drives the plow shovel 4 to rotate back and forth in a limited manner, thereby causing the plow shovel 4 to vibrate, which can effectively shake off the soil on the plow shovel 4 and reduce the resistance of the plow shovel 4. The drive device can also use a vibrator and is powered by a solar cell. The shaping plow 5 is installed at the rear end of the plow shovel 4 to shape the soil mound.

[0024] The connection structure 3 shown in Embodiment 2 of this application includes an upper clamping plate 7, a lower clamping plate 8, an arc-shaped support base 9, an arc-shaped turntable 10, a sector-shaped connecting plate 11, and a mounting rod 12. The upper clamping plate 7 and the lower clamping plate 8 are clamped onto the support beam 2 and fixed with bolts. Both the upper clamping plate 7 and the lower clamping plate 8 are clamped onto the support beam 2 and fixed with bolts, which can effectively prevent the upper clamping plate 7 and the lower clamping plate 8 from sliding left and right. An arc-shaped support base 9 is provided at the bottom of the lower clamping plate 8. An arc-shaped opening groove 13 is provided on the arc surface of the arc-shaped support base 9. A rotating shaft is rotatably installed in the arc-shaped support base 9. The rotating shaft is fixedly connected to the sector-shaped connecting plate 11 to prevent the sector-shaped connecting plate 11 from sliding left and right. An arc-shaped turntable is installed at one end of the sector-shaped connecting plate 11 that passes through the arc-shaped opening groove 13. 10. The fan-shaped connecting plate 11 does not slide left or right, which can effectively prevent the arc-shaped turntable 10 from sliding left or right. The arc-shaped opening groove 13 is slightly larger than the fan-shaped connecting plate 11, so that the fan-shaped connecting plate 11 can slide back and forth within the arc-shaped opening groove 13. The arc-shaped turntable 10 is matched with the arc-shaped support seat 9. The arc-shaped turntable 10 is mounted with the plow 4 through the mounting rod 12. The arc-shaped turntable 10 does not slide left or right, which can prevent the plow 4 mounted on the arc-shaped turntable 10 from sliding. The fan-shaped connecting plate 11 rotates and is limited by the arc-shaped opening groove 13, so that the fan-shaped connecting plate 11 is pressed against the front and rear ends of the arc-shaped opening groove 13, which can generate vibration, thereby causing the arc-shaped turntable 10 mounted on the fan-shaped connecting plate 11 to vibrate back and forth, and thus causing the plow 4 to vibrate back and forth.

[0025] Figure 3In this embodiment 3, the drive device 6 includes a transmission rod 14, a connecting rod 15, a top plate 16, a lifting rod 17, a small roller 18, a plum blossom-shaped cam 19, a support plate 20, a sealing shell 21, and a grounding wheel 22. One end of the transmission rod 14 is connected to the rotating component of the connecting structure 3, and the other end is connected to the connecting rod 15. The top plate 16 is fixedly installed on the connecting rod 15. A crossbeam 23 and a support plate 20 are provided on the plow frame 1 below the top plate 16. The lifting rod 17 is slidably installed on the crossbeam 23 through an upper linear bearing 24, so that the lifting rod 17 can be slidably installed on the crossbeam 23. The lever 17 can be raised and lowered more quickly; the plow frame 1 is equipped with two support plates 20, and mounting plates 25 are slidably installed at the lower ends of both support plates 20. A buffer spring 26 is installed between the support plates 20 and the mounting plates 25 to provide a certain buffer between the support plates 20 and the mounting plates 25, preventing the support plates 20 and the mounting plates 25 from supporting the plow frame 1 and causing the plow frame 1 to not press into the soil. A rotating shaft 27 is rotatably installed between the two mounting plates 25. A plum blossom-shaped cam 19 is fixedly installed in the middle of the rotating shaft 27. Rotating shafts on both sides of the plum blossom-shaped cam 19 A grounding wheel 22 is fixedly installed on the shaft 27. The grounding wheel 22 drives the rotating shaft 27 to rotate, and the rotating shaft 27 drives the plum blossom-shaped cam 19 to rotate. A sealing shell 21 is provided on the outside of the plum blossom-shaped cam 19 to prevent soil from hindering the operation of the plum blossom-shaped cam 19. The sealing shell 21 is rotatably mounted on the rotating shaft 27. A lower linear bearing 28 is installed on the sealing shell 21 to enable the lifting rod 17 to work quickly and also to support the lifting rod 17. The lower end of the lifting rod 17 passes through the lower linear bearing 28 and extends into the sealing shell 21. A rotatable bearing is installed at the lower end of the lifting rod 17. The small roller 18 cooperates with the plum blossom-shaped cam 19. The plum blossom-shaped cam 19 intermittently applies an upward thrust to the lifting rod 17 through rotation. The top of the lifting rod 17 contacts the top plate 16. The lifting rod 17 pushes the end of the top plate 16 to move upward, thereby driving the connecting rod 15 to move upward, and then driving the transmission rod 14 to move upward, thereby pulling the rotating part of the connecting structure 3 to rotate forward, thus realizing the forward rotation of the plow 4. When the thrust of the lifting rod 17 is gone, the soil will push the plow 4 to rotate backward, thus realizing reciprocating motion.

[0026] Embodiment 4 of this application shows that a rear connecting rod 29 is installed at the rear end of the plow shovel 4, and a shaping plow 5 is installed on the rear connecting rod 29. The front end of the shaping plow 5 is provided with an arc-shaped soil collecting plate 30, which can effectively collect soil, and then the shaping plow 5 shapes the soil.

[0027] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
