Abstract
Description
Technical Field
[0001] This invention relates to the field of micro-tiller technology, specifically to a tillage method, system, and micro-tiller. Background Technology
[0002] In modern agricultural production, mini tillers, as important small-scale tillage equipment, are widely used for soil tillage in small plots of farmland, orchards, vegetable gardens, and other areas. With the increasing demand for precision and intelligent agriculture, higher requirements are being placed on the operating efficiency, adaptability, and ease of operation of mini tillers. Traditional mini tillers mainly rely on manual operation and simple mechanical transmission to complete tillage tasks, making it difficult to meet the needs of complex and ever-changing agricultural production environments.
[0003] Currently, most micro-tillers on the market typically consist of a power system, a transmission system, tillage blades, and a control handle. Their working principle involves the power system outputting power, which is transmitted through the transmission system to the tillage blades, causing them to rotate and till the soil. Structurally, the working depth of the tillage blades is mostly adjusted manually by inserting or removing pins or rotating screws to change the installation position of the blades; the machine's stability mainly relies on a fixed support structure and lacks self-adjusting capabilities.
[0004] However, existing mini-tillers have many problems in actual farmland operations. For example, when operating in soil environments with varying moisture levels, if the soil moisture is high, the mini-tiller is prone to sinking and shaking, causing deviations in the tillage trajectory and affecting tillage quality. If the soil moisture is low and the texture is hard, traditional mini-tillers cannot automatically adjust the blade speed and working depth according to soil hardness, resulting in either low tillage efficiency or machine damage due to excessive load. Furthermore, manually adjusting the blade depth is not only cumbersome and time-consuming, but also difficult to guarantee accuracy and consistency. The root cause of these problems lies in the lack of intelligent sensing and adaptive adjustment functions in existing mini-tillers. They cannot adjust working parameters and their own status in real time according to actual soil conditions, greatly limiting the application range and operating efficiency of mini-tillers and failing to meet the development needs of intelligent and efficient modern agriculture. Therefore, this invention provides a tillage method, system, and mini-tiller to address the shortcomings of existing technologies. Summary of the Invention

Two pads 410 are fixedly connected to the outer side of the frame 402. The top of the pads 410 is fitted with... The system is equipped with a geared motor 411, the output end of which is fixedly connected to a take-up roller 412. A pull rope 413 is fixedly connected to the outer side of the take-up roller 412. Two U-shaped frames 414 are fixedly connected to the top of the support plate 403. The other end of the pull rope 413 is fixedly connected to the outer side of the U-shaped frame 414. The tillage mechanism 5 includes two mounting plates 501, which are fixedly connected to the outer sides of the micro-tiller body 1. Telescopic rods 502 are fixedly connected to the bottom of the mounting plates 501. Rotating rods 503 are rotatably connected to the bottom ends of the two telescopic rods 502. Multiple deep tillage blades 504 are fixedly connected to the outer side of the rotating rods 503. A servo motor 506 is installed inside the micro-tiller body 1. A lead screw 507 is fixedly connected to the output end of 506. A guide rod 508 is fixedly connected to the bottom of the micro-tiller body 1. A connecting plate 511 is fixedly connected to the bottom of the guide rod 508. The bottom of the lead screw 507 is rotatably connected to the top of the connecting plate 511. A movable seat 509 is provided outside the lead screw 507 and the guide rod 508. Two arc-shaped connecting rods 510 are fixedly connected to the outside of the movable seat 509. A motor box 505 is fixedly connected to the bottom of the two arc-shaped connecting rods 510. A dual-shaft motor is installed inside the motor box 505, and its output end is fixedly connected to the rotating rod 503. A protective plate 513 is fixedly connected to the outside of one of the arc-shaped connecting rods 510. Two side plates 512 are fixedly connected to the outside of the connecting plate 511.
[0028] Specifically, in the actual use of the mini tiller, the user first holds the handle on the grip frame 2, which provides a stable grip point for operating the mini tiller. The dual-axis motor inside the motor housing 505 is then started. The powerful output of the dual-axis motor drives the two rotating rods 503 to rotate at high speed. Since multiple deep-tillage blades 504 are fixedly connected to the outer side of the rotating rods 503, the rotation of the rotating rods 503 drives the deep-tillage blades 504 to rotate synchronously. These high-speed rotating deep-tillage blades 504 cut into the soil, breaking up and turning it over, thus enabling efficient cultivation of the land.
[0029] Meanwhile, the support plate 403 plays a crucial role. Its bottom can be inserted into the soil for support, providing additional stability to the entire tiller and preventing it from swaying or tilting during operation. High-precision soil moisture sensors are installed on both outer sides of the support plate 403. During operation, these sensors detect soil moisture in real time and convert the detected data into electrical signals. These signals are quickly transmitted to two geared motors 411, which then activate, driving the winding roller 412 to rotate. As the winding roller 412 rotates, the pull rope 413 is gradually pulled and wound up. Since the other end of the pull rope 413 is fixedly connected to the outside of the U-shaped frame 414, and the U-shaped frame 414 is fixed to the top of the support plate 403, the winding of the pull rope 413 causes the support plate 403 to move downwards.
[0030] During the downward movement of the support plate 403, the ingenious design between toothed plate 405 and toothed plate 409 plays a crucial role. Toothed plate 405 is fixedly connected to the outer sides of the support plate 403, while toothed plate 409 is fixedly connected to the inner sides of the fixed frame 402 via two telescopic rods 407. Toothed plate 405 and toothed plate 409 are inclined surfaces that fit together. When the support plate 403 is pulled downward by the rope 413, toothed plate 405 gradually descends along the inclined surface of toothed plate 409, continuously shifting and engaging with it. During this process, the spring 408 sleeved on the outside of the telescopic rod 407 acts as a buffer and reset mechanism. One end of the spring 408 is fixedly connected to the inner side of the fixed frame 402, and the other end is fixedly connected to the outer side of toothed plate 409. When toothed plate 405 moves downward, the spring 408 is compressed, storing elastic potential energy. The flat surface of toothed plate 409 can limit toothed plate 405, ensuring that the downward-moving support plate 403 can maintain a stable position and will not shake or shift arbitrarily. When the support plate 403 needs to be reset, the operator only needs to manually push the two toothed plates 409 apart, making them distanced from toothed plate 405. At this time, under the action of the elastic potential energy of spring 408, the support plate 403 can be easily moved upward and returned to the initial position, facilitating subsequent adjustments.
[0031] When the tillage mechanism 5 is working, pressure sensors responsible for detecting soil hardness play a crucial role. These pressure sensors are installed at the connection between the deep tillage blade 504 and the rotating rod 503, or other locations that can accurately sense the feedback force exerted by the deep tillage blade 504 during operation. When the deep tillage blade 504 operates in the soil, it experiences a reaction force from the soil. The pressure sensors can accurately detect the magnitude of this force and convert it into an electrical signal. Based on the detected soil hardness data, the control system automatically adjusts the speed of the dual-shaft motor in the motor housing 505. For example, when the detected soil hardness is high, the control system increases the speed of the dual-shaft motor, allowing the deep tillage blade 504 to obtain greater cutting force for better soil breaking; when the soil hardness is low, the speed of the dual-shaft motor is appropriately reduced to save energy and avoid over-tillage that could damage the soil structure.
[0032] Simultaneously, the signal from the pressure sensor also activates the servo motor 506. A lead screw 507 is fixedly connected to the output end of the servo motor 506, and a guide rod 508 is fixedly connected to the bottom of the tiller body 1. A movable seat 509 is provided outside the lead screw 507 and the guide rod 508. When the servo motor 506 starts, it drives the lead screw 507 to rotate. Because the guide rod 508 guides the movable seat 509, the movable seat 509 can only move up and down along the direction of the guide rod 508. Two arc-shaped connecting rods 510 are fixedly connected to the outer side of the movable seat 509, and a motor housing 505 is fixedly connected to the bottom of the two arc-shaped connecting rods 510. Therefore, the up and down movement of the movable seat 509 drives the overall blade assembly (including the motor housing 505, the rotating rod 503, the deep tillage blade 504, etc.) to adjust its position. When the soil is hard, the moving seat 509 moves the blade assembly downwards, increasing the working depth of the deep tillage blades 504 to break up the hard soil more thoroughly. When the soil is soft, the moving seat 509 moves the blade assembly upwards, reducing the working depth and avoiding unnecessary energy consumption and soil disturbance. Through this intelligent adjustment method, the mini tiller can automatically optimize tillage parameters according to different soil hardness conditions, improving tillage efficiency and quality, and better meeting the actual needs of agricultural production.
[0033] Working principle: The user can hold the handle on the holding frame 2 and start the dual-axis motor inside the motor box 505 to drive the two rotating rods 503 to rotate. This drives the deep tillage blade 504 to rotate, thus tilling the land. The bottom of the support plate 403 can be inserted into the soil for support. The sensor on the outside of the support plate 403 can detect the soil moisture and transmit an electrical signal to the two reduction motors 411, thereby driving the winding roller 412 to rotate. This can pull the rope 413 to wind up the soil. The inclined surfaces of the toothed plate 1 405 and the toothed plate 2 409 fit together, allowing the position of the toothed plate 1 405 to gradually decrease and engage with the toothed plate 2 409. By continuously interlocking and shifting, the plane of the second toothed plate 409 can limit its movement, thus keeping the downward-moving support plate 403 in a stable position. When the support plate 403 needs to be reset, the two second toothed plates 409 can be pushed apart from the first toothed plate 405, allowing the support plate 403 to be easily moved upward. In addition, the pressure sensor responsible for detecting soil hardness can detect soil hardness by receiving feedback force from the deep tillage blade 504 during operation, thereby changing the speed of the dual-axis motor in the motor housing 505 and starting the servo motor 506 to drive the lead screw 507 to rotate. This allows the moving seat 509 to adjust the position of the entire tool assembly, thereby changing the working depth.
