Technical Field
[0001] This utility model relates to the field of rotary tillers, specifically a rotary tiller structure for agricultural rotary tillers. Background Technology
[0002] Rotary tillers are primarily used for plowing and harrowing operations, characterized by their strong soil-breaking ability and ability to create a flat surface after tilling. They can chop up stubble buried below the surface, facilitating seeder operations and providing a good seedbed for later sowing. Furthermore, rotary tillers can break up the plow pan, restore soil structure, improve soil water retention, eliminate some weeds, reduce pests and diseases, level the surface, and improve the standard of agricultural mechanization. Rotary tillers have a wide range of applications, suitable for various farmland operations, and perform particularly well in situations requiring surface leveling and soil breaking. Using rotary tillers can improve agricultural production efficiency, reduce labor intensity, and adapt to different soil conditions, meeting diverse agricultural needs.
[0003] In existing dryland operations, the tractor drives the rotary tiller mechanism, which rotates under power to cut the soil. The cut soil clods collide and break up, resulting in a uniform and flat surface without furrows. However, the rotary tiller mechanisms used in existing agricultural rotary tillers still have the following problems during use:
[0004] Existing rotary tillage mechanisms are towed by tractors. Since there are no corresponding reference points while the tractor is moving, it is difficult for the tractor to drive the rotary tillage mechanism in a straight line, resulting in irregular soil loosening and affecting the appearance of the soil. At the same time, the rotary tillage mechanism cannot locate the field to develop equidistant field ridges, which is inconvenient for personnel to walk on the field ridges later. Therefore, it is necessary to develop a rotary tillage structure for agricultural rotary tillers to be used in the field of existing tillage machines. Utility Model Content
[0005] To address the shortcomings of existing technologies, which lack corresponding reference points during operation, making it difficult for tractors to drive the rotary tillage mechanism in a straight line, resulting in irregular soil loosening and affecting the aesthetics of the loosened soil, and also making it difficult for the rotary tillage mechanism to position the field and develop equidistant field ridges, thus hindering the movement of personnel along the ridges, this utility model proposes a rotary tillage structure for an agricultural rotary tiller.

[0010] The adjustment mechanism includes a movable block, which is movably assembled with two connecting rods. An operating plate is fixedly mounted on the top of each movable block. Assembly grooves are provided on both symmetrical sides of the pressure block. A vertical rod is fixedly mounted on the bottom of each movable block.

When the rotary tillage mechanism loosens the soil, it can create indentations in the soil based on the traction reference pressure blocks, thus guiding the tractor's straight-line movement and improving the aesthetics of soil loosening. Simultaneously, rotating the adjusting bolt on the limit block causes the rotating disk on the movable rod to rotate in the rotating cavity. The operating block moves on the two operating rods, and the guide rod... Under the action of the mechanism, the movable blocks move on the connecting rod, and the indicator rod moves on the moving port. The indicator rod corresponds to the data on the scale line, allowing the movable blocks to move quantitatively on the connecting rod. The connecting rod drives the horizontal bar on the vertical rod to move, which in turn drives the adjusting block to move on the assembly slot, increasing the width of the field ridges cultivated by the control block on the soil, facilitating pedestrian traffic later. The traction frame is then installed on the tractor, and the operating motor is started, causing the second sprocket to drive the first sprocket to rotate via the chain. The first sprocket drives the loosening blade to rotate via the rotating shaft, making it easier for the loosening blade to loosen the soil and improve the usage effect. Attached Figure Description

A connecting block 22 is fixedly mounted on one end of the mounting frame 10. A mounting block 23 is fixedly mounted on one end of the connecting block 22. A traction port 40 is symmetrically provided through the mounting block 23. Guide rods 41 are symmetrically fixedly mounted on the traction port 40. A positioning mechanism is mounted on the mounting block 23. The positioning mechanism includes a traction block 42, which is movably assembled with the two guide rods 41.

The other end of the adjusting rod 61 is movably mounted to the mounting plate 43. When the cylinder 51 is activated, the piston rod 52 drives the adjusting block 53 to move. Under the action of the adjusting rod 61, the traction block 42 moves on the guide rod 41.
[0042] Reference Figure 1 and Figure 2A traction frame 11 is fixedly mounted on the top of the mounting frame 10, and a dustproof box 20 is fixedly mounted on the side of the mounting frame 10. A rotating shaft 12 is movably mounted on the mounting frame 10, with one end of the rotating shaft 12 extending into the interior of the dustproof box 20.

Multiple soil loosening blades 13 are fixedly mounted on the rotating shaft 12. The traction frame 11 is installed with the tractor, and the operating motor 21 is started, causing the second sprocket 32 to drive the first sprocket 31 to rotate via the chain 33. The first sprocket 31 then drives the soil loosening blades 13 to rotate via the rotating shaft 12, making it easier for the soil loosening blades 13 to loosen the soil.
[0043] Working principle: Starting cylinder 51 causes piston rod 52 to move adjusting block 53. Under the action of adjusting rod 61, traction block 42 moves on guide rod 41, causing traction block 42 to move assembly block 63 on extension block 62. Assembly block 63 moves reference pressing block 83, adjusting the distance between the two reference pressing blocks 83. When the rotary tillage mechanism loosens the soil, it can create indentations on the soil based on the traction reference pressing block 83, thus positioning the tractor for straight-line travel and improving the aesthetics of loosening the soil. Simultaneously, rotating adjusting bolt 99 on limit block 95 causes rotating disk 86 on movable rod 85 to rotate in rotating cavity 84. Operating block 96 moves on two operating rods 94, under the action of guide rod 98... This allows the movable block 72 to move on the connecting rod 71, and the indicator rod 81 to move on the moving port 73. The indicator rod 81 corresponds to the data on the scale line 80, allowing the movable block 72 to move quantitatively on the connecting rod 71. The connecting rod 71 drives the horizontal bar 93 on the vertical rod 92 to move, which in turn drives the adjusting pressure block 91 to move on the assembly slot 90, increasing the width of the field ridges cultivated by the control pressure block 83 in the soil, facilitating pedestrian movement later. The traction frame 11 is then installed on the tractor, and the operating motor 21 is started, causing the second sprocket 32 to drive the first sprocket 31 to rotate via the chain 33. The first sprocket 31 then drives the loosening blade 13 to rotate via the rotating shaft 12, making it easier for the loosening blade 13 to loosen the soil and improve the usage effect.
