Description

Technical Field

[0001] The present invention relates to the technical field of rotary tillers, and specifically to a multi-functional rotary tiller for farming. Background Art

[0002] A rotary tiller for farming is a mechanical device commonly used in agricultural production, mainly for tillage operations. It loosens and refines the soil by rotating blades or shovels, thereby improving the soil structure and promoting the growth of crops. The rotary tiller is usually used in conjunction with agricultural machinery such as tractors. Its working principle is to loosen the soil through mechanical rotation and mix it with air, making the soil more conducive to the absorption of water and nutrients.

[0003] In the prior art, the Chinese patent with the publication number "CN211481873U" discloses a deep tillage rotary tiller. The external drive motor works and drives the transmission shaft and the driving bevel gear to rotate. The bottom of the driving bevel gear meshes with the driven bevel gear, so that the driven bevel gear drives the rotating shaft and the driving gear to rotate. Both ends of the driving gear mesh with the toothed plates, so that the two toothed plates move towards the opposite sides of the front and back, and the slider moves in the slide rail. Since a T-shaped groove is provided in the slide rail, the stability of the slider during movement is ensured. The slider moves, drives the connecting column rod and the rotary tillage shaft, and adjusts the positions of the two rotary tillage shafts, thereby adjusting the tillage area. This solves the problem that when the existing rotary tiller is in use, due to different tillage land areas, it is necessary to adjust the tillage area of the rotary tiller. Although the rotary tillage shaft can be manually disassembled and assembled to achieve the adjustment purpose, this is not only time-consuming and laborious, but also inconvenient to use.

[0004] In the above solution, the tillage area of the rotary tiller is realized by automatically adjusting the positions of the two rotary tillage shafts. However, in this solution, after the soil is turned over by the rotary tillage teeth, the soil surface will be uneven. Although the tail plate of the rotary tiller can be used to ensure the uniformity of the tillage layer, the leveling effect of the tail plate of the rotary tiller is often affected by the soil hardness. When the soil is hard, the tail plate may not be able to effectively level the soil, and may even cause machine damage or reduced work efficiency. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a multi-functional rotary tiller for farming, which solves the problems mentioned in the above background art.

[0011] Preferably, the lifting rod is slidably installed in the lifting hole. The positioning slider is slidably connected to the positioning sliding groove. The hydraulic cylinder drives the lifting rod to lift. By the limiting sliding of the positioning slider in the positioning sliding groove and the function of the second bearing, when the height of the lifting rod is adjusted, it will not affect the rotation of the positioning vertical rod.

[0012] Preferably, a connecting column rod is fixedly installed at the bottom end of the lifting rod.

[0015] The present invention provides a multi-functional rotary tiller for farming. Compared with the prior art, it has the following beneficial effects: 1. In the present invention, when the drive shaft on the drive housing drives the blade to rotate, it will synchronously drive the driving sprocket to rotate. The driving sprocket drives the driven sprocket to rotate through a chain. When the driven sprocket rotates, it will drive the linkage shaft to rotate between the two positioning frame plates.

The leveling rod on the positioning vertical rod will rotate through the leveling blade, and the leveling blade is used to level the plowed soil to ensure the uniformity and flatness of the soil for the growth of crops; 2. In the present invention, when it is necessary to adjust the height of the leveling rod, the hydraulic cylinder drives the lifting rod to slide in the lifting hole on the positioning vertical rod, and the positioning slider on the lifting rod is limited to slide in the positioning chute. At the same time, the hydraulic cylinder will, through the action of the second bearing and the cooperation between the positioning slider and the positioning chute, complete the height adjustment of the leveling rod without affecting the rotation of the positioning vertical rod, ensuring that the leveling rod can maintain efficient operation and ensure the operation quality during the adjustment process, effectively improving the use effect of the entire rotary tiller; 3. In the present invention, when it is necessary to adjust the angle of the leveling rod, the electric push rod on the installation ring is started, and the electric push rod is used to drive the lifting ring to limit the lifting on the connecting column rod. When the lifting ring descends, the lifting rod will, through the cooperation of the adjusting rod and the U-shaped frame plate on the leveling rod, cause the leveling rod to rotate downward around the rotation groove. When the lifting ring rises, the lifting rod will, through the cooperation of the adjusting rod and the U-shaped frame plate on the leveling rod, cause the leveling rod to rotate upward around the rotation groove. Through the precise adjustment of the angle of the leveling rod, it is ensured that the leveling rod can adjust its angle according to needs during rotary tillage operations, optimizing the tillage effect; 4. In the present invention, through the combined use of the linkage component, the leveling component and the adjusting component, the performance of the rotary tiller in soil leveling and adjustment is optimized, enabling it to better cope with different tillage conditions, improving the quality of the soil, and providing a better growth environment for crops.

When the lifting ring 34 descends, the lifting rod 23 will cooperate with the U-shaped frame plate 30 on the leveling rod 10 through the adjusting rod 31, so that the leveling rod 10 rotates downward with the rotation groove 29 as the center. When the lifting ring 34 rises, the lifting rod 23 will cooperate with the U-shaped frame plate 30 on the leveling rod 10 through the adjusting rod 31, so that the leveling rod 10 rotates upward with the rotation groove 29 as the center.

The leveling rod 10 on the positioning vertical rod 18 will rotate through the leveling blade 11, and the leveling blade 11 is used to level the tilled soil to ensure the uniformity and flatness of the soil; When the height of the leveling rod 10 needs to be adjusted, the hydraulic cylinder 22 drives the lifting rod 23 to slide in the lifting hole 25 on the positioning vertical rod 18, and the positioning slider 24 on the lifting rod 23 is limited to slide in the positioning chute 26. At the same time, the hydraulic cylinder 22 will, through the action of the second bearing 21 and the cooperation of the positioning slider 24 and the positioning chute 26, complete the height adjustment of the leveling rod 10 without affecting the rotation of the positioning vertical rod 18, ensuring that the leveling rod 10 can maintain high-efficiency operation and ensure the operation quality during the adjustment process; When the angle of the leveling rod 10 needs to be adjusted, the electric push rod 33 on the mounting ring 32 is activated, and the electric push rod 33 drives the lifting ring 34 to limit the lifting on the connecting column rod 27. When the lifting ring 34 descends, the lifting rod 23 will cooperate with the U-shaped frame plate 30 on the leveling rod 10 through the adjusting rod 31, so that the leveling rod 10 rotates downward with the rotation groove 29 as the center.
