Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of tillage blade connectors, and in particular to a resistance tillage blade connector for a micro-tiller. Background Technology
[0002] The resistance blade connector for mini-tillers is a key functional component in the field of agricultural mechanization. It is designed specifically for small mini-tillers and is essentially a precision mechanical component that connects the resistance blades to the power system of the mini-tiller. It is forged from high-strength alloy steel or wear-resistant composite materials.
[0003] When using blade connectors, in traditional mini-tiller operation scenarios, existing blade connectors mostly adopt a fixed installation structure. Their tillage angle cannot be adjusted in real time according to environmental parameters such as soil hardness and moisture. When facing high-hardness soil or wet clay soil, the fixed-angle blades will have too large a contact area with the soil and too high resistance, resulting in a surge in the mini-tiller's traction resistance, serious energy waste, and even overload damage to the equipment. In scenarios such as alternating dryland and paddy field operations or switching between different soil textures, operators need to manually disassemble and replace blade components with different angles. This is not only time-consuming and labor-intensive, but also difficult to accurately match real-time soil conditions, seriously restricting operating efficiency and equipment adaptability, becoming a key technical bottleneck restricting the intelligent and efficient development of mini-tillers.
[0004] Therefore, to address the issue of difficulty in adjusting the tillage angle based on soil conditions when using the device in scenarios involving different soil textures, a resistance-adjusting blade connector for micro-tillers can be designed. When in use, this connector consists of a main frame formed by two symmetrically arranged mounting seats. Each mounting seat is rotatably connected to an adjusting seat via a rotating shaft. The resistance-adjusting blade is fixedly installed between the two adjusting seats. When angle adjustment is required, a lifting mechanism is activated, driving the adjusting mechanism to rotate. The adjusting mechanism transmits the rotational motion to the rotating shaft, thereby causing the adjusting seat and blade to deflect around the axis of rotation. By controlling the extension and retraction of the lifting mechanism, the tillage angle of the blade can be precisely adjusted to adapt to different soil hardness operating environments. In summary, this device, through a combination of hydraulic drive and gear transmission, achieves stepless adjustment of the blade angle, allowing real-time adjustment of the tillage angle based on soil resistance, effectively reducing tillage resistance, decreasing energy consumption of the micro-tiller, and improving operating efficiency. Utility Model Content
[0005] To overcome the problem that existing tillage blade connectors mostly adopt a fixed installation structure, the fixed angle of the tillage blade will cause the contact area with the soil to be too large and the resistance to be too high, resulting in a surge in the traction resistance of the micro tiller and serious energy waste. Therefore, when used in scenarios with different soil textures, it is inconvenient to adjust the tillage angle according to the soil conditions.

When angle adjustment is required, the lifting mechanism is activated to drive the adjusting mechanism to achieve rotation. The adjusting mechanism transmits the rotational motion to the rotating shaft, thereby causing the adjusting seat and tiller blade to deflect around the axis of rotation. By controlling the extension and retraction of the lifting mechanism, the tilling angle of the tiller blade can be precisely adjusted to adapt to different soil hardness operating environments. In summary, this device, through a combination of hydraulic drive and gear transmission, achieves stepless adjustment of the tiller blade angle.

Each set of mounting seats is rotatably connected to an adjusting seat via a rotating shaft. The resistance tiller blade is fixedly installed between the two adjusting seats. When angle adjustment is required, the lifting mechanism is activated to drive the adjusting mechanism to rotate. The adjusting mechanism transmits the rotational motion to the rotating shaft, thereby causing the adjusting seat and tiller blade to deflect around the axis of rotation. By controlling the extension and retraction of the lifting mechanism, the tilling angle of the tiller blade can be precisely adjusted to adapt to different soil hardness operating environments. In summary, this device, through a combination of hydraulic drive and gear transmission, achieves stepless adjustment of the tiller blade angle.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] Please see Figure 1 and Figure 5 This utility model provides an embodiment: a micro-tiller resistance blade connector, including two sets of mounting seats 1, each set of mounting seats 1 having an adjustment seat 2 on its inner side, and a rotating shaft 3. Each set of adjustment seats 2 is rotatably connected to each set of mounting seats 1 by a rotating shaft 3. The upper end of the adjustment seat 2 is fixedly sleeved on the outer wall of the rotating shaft 3, and the rotating shaft 3 is rotatably connected through the interior of the mounting seat 1. One side of one set of mounting seats 1 is provided with a lifting mechanism, and the outer wall of one set of mounting seats 1 is provided with an adjustment mechanism.
[0025] Please see Figure 3 and Figure 6 The lifting mechanism includes a hydraulic telescopic rod 4 and a guide toothed plate 5. One side of a set of mounting bases 1 is provided with a hydraulic telescopic rod 4, and the other side of a set of mounting bases 1 is provided with a guide toothed plate 5. The telescopic end of the hydraulic telescopic rod 4 is fixedly connected to the bottom of the guide toothed plate 5. When the hydraulic telescopic rod 4 is activated, its telescopic end drives the guide toothed plate 5 to move in the vertical direction. One side of the outer wall of a set of mounting bases 1 is provided with a guide groove 6. A guide post 7 is fixedly provided inside the guide groove 6. A guide seat 8 is slidably sleeved on the outer wall of the guide post 7. The guide seat 8 is fixedly connected to the guide toothed plate 5. The guide toothed plate 5 slides with the guide post 7 in the guide groove 6 of the mounting base 1 through the guide seat 8 to ensure that the movement trajectory is stable and without deviation.
[0026] Please see Figure 2 and Figure 4The adjusting mechanism includes a worm gear 9, an adjusting gear 10, and a protective shell 11. A protective shell 11 is fixedly installed on the outer wall of a set of mounting bases 1. A worm gear 9 is rotatably mounted inside the protective shell 11. An adjusting gear 10 is fixedly installed on one side of the worm gear 9. During the lifting and lowering of the guide gear plate 5, its teeth mesh with the adjusting gear 10, driving the adjusting gear 10 to rotate. The adjusting gear 10 is fixed to the end of the worm gear 9, thus the worm gear 9 rotates synchronously. One side of the worm gear 9 extends through and rotatably outside one side of the protective shell 11. The adjusting gear 10 and the guide gear... When the guide tooth plate 5 is engaged, its tooth surface engages with the adjusting gear 10 during the lifting and lowering process, driving the adjusting gear 10 to rotate. The adjusting mechanism also includes a worm gear 12. The end of a set of rotating shafts 3 is rotatably mounted inside the protective shell 11. The end of a set of rotating shafts 3 is fixedly mounted with a worm gear 12. The worm 9 engages with the worm gear 12. The worm 9 engages with the worm gear 12 fixed at the end of the rotating shaft 3. The rotational motion is transmitted to the rotating shaft 3 through the worm gear 12 and worm 9, thereby driving the adjusting seat 2 and the tiller to deflect around the axis of the rotating shaft 3.
[0027] When the blade connector is in use, the working principle of the micro-tiller resistance blade connector of this utility model is as follows: The device consists of two sets of symmetrically arranged mounting seats 1 forming the main frame. The inner side of each set of mounting seats 1 is rotatably connected to the adjustment seat 2 through the rotating shaft 3, and the resistance blade is fixedly installed between the two sets of adjustment seats 2.
[0028] When angle adjustment is required, the hydraulic telescopic rod 4 is activated, and its telescopic end drives the guide tooth plate 5 to move in the vertical direction. At this time, the guide tooth plate 5 slides with the guide column 7 in the guide groove 6 of the mounting seat 1 through the guide seat 8, ensuring that the movement trajectory is stable and without deviation.
[0029] During the lifting and lowering process of the guide tooth plate 5, its tooth surface meshes with the adjusting gear 10, driving the adjusting gear 10 to rotate. The adjusting gear 10 is fixed to the end of the worm 9, so the worm 9 rotates synchronously. The worm 9 meshes with the worm wheel 12 fixed to the end of the rotating shaft 3. The rotational motion is transmitted to the rotating shaft 3 through the worm wheel 12 and the worm 9, thereby driving the adjusting seat 2 and the tiller to deflect around the axis of the rotating shaft 3. By controlling the extension and retraction of the hydraulic telescopic rod 4, the tillage angle of the tiller can be precisely adjusted to adapt to the needs of different soil hardness operating environments.
[0030] The device achieves automated adjustment of the tiller blade angle through a mechanical transmission chain. The worm gear 12 and worm 9 transmission have self-locking characteristics, which can reliably lock the tiller blade position after the angle is adjusted to the correct position, preventing angle deviation caused by vibration or external force during operation. The sliding fit structure between the guide tooth plate 5 and the guide post 7 effectively constrains the direction of movement during the adjustment process, avoids lateral sway caused by uneven force, and ensures the accuracy of angle adjustment.
[0031] In summary, firstly, the combination of hydraulic drive and gear transmission enables stepless adjustment of the tillage blade angle, allowing for real-time adjustment based on soil resistance, effectively reducing tillage resistance, minimizing energy consumption, and improving operational efficiency. Secondly, the self-locking function of the worm gear 12 and worm 9 ensures stable and reliable adjustment of the blade angle, preventing angle changes due to vibration during operation and guaranteeing tillage quality. Thirdly, the guide mechanism design makes the motion trajectory precise and controllable, improving the smoothness and repeatability of the adjustment process. Fourthly, the device has a compact overall structure; the mounting base 1 is fixedly connected to the mini-tiller body, and the adjustment base 2 is fixedly connected to the tillage blade, forming a stable transmission system and enhancing the mini-tiller's adaptability to complex tillage environments. Fifthly, mechanical transmission replaces manual adjustment, reducing operational intensity and improving the level of automation. In conclusion, this connector, through its scientific structural design, achieves precise, stable, and automatic adjustment of the tillage blade angle, effectively solving the technical problems of high tillage resistance, high energy consumption, and inconvenient adjustment in traditional mini-tillers.
[0032] Through the above steps, when the tiller blade connector is in use, the device consists of two sets of symmetrically arranged mounting seats 1 forming the main frame. The inner side of each set of mounting seats 1 is rotatably connected to the adjusting seat 2 via a rotating shaft 3. The resistance tiller blade is fixedly installed between the two sets of adjusting seats 2. When angle adjustment is required, the lifting mechanism is activated to drive the adjusting mechanism to achieve adjustment rotation. The adjusting mechanism transmits the rotational motion to the rotating shaft 3, thereby causing the adjusting seat 2 and the tiller blade to deflect around the axis of the rotating shaft 3. By controlling the extension and retraction of the lifting mechanism, the tillage angle of the tiller blade can be precisely adjusted to adapt to the working environment requirements of different soil hardness. In summary, this device achieves stepless adjustment of the tiller blade angle through a combination of hydraulic drive and gear transmission. It can adjust the tillage angle in real time according to soil resistance, effectively reducing tillage resistance, reducing the energy consumption of the micro-tiller, and improving working efficiency.
[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
