Description

Technical Field

[0001] The present invention relates to the technical field of micro-tillage machines, and in particular to a farming method, a system and a micro-tillage machine. Background Art

[0002] In modern agricultural production, micro-tillage machines, as important small-scale tillage equipment, are widely used for soil tillage operations in small farmlands, orchards, vegetable plots, and other areas. With the increasing demand for refined and intelligent agricultural development, micro-tillage machines are facing higher requirements in terms of efficiency, adaptability, and ease of operation. Traditional micro-tillage machines rely primarily on manual operation and simple mechanical transmission to complete tillage tasks, which makes them difficult to meet the needs of the complex and changing agricultural production environment.

[0003] Currently, common tillage machines on the market typically consist of a power system, transmission system, tilling blade components, and operating handles. Their operating principle is that power is transmitted from the power system to the tilling blade components through the transmission system, driving the blades to rotate and till the soil. Structurally, the working depth of the tilling blades is often manually adjusted by inserting or removing pins or turning screws to change the installation position of the tilling blade components. The machine's stability primarily relies on a fixed support structure and lacks adaptive adjustment capabilities.

[0004] However, in actual farmland operation scenarios, existing micro-tillage machines have many problems. For example, when operating in soil environments with different humidity, if the soil humidity is high, the micro-tillage machine is prone to sinking and shaking, causing the tillage trajectory to deviate, affecting the quality of tillage; if the soil humidity is low and the texture is hard, the traditional micro-tillage machine cannot automatically adjust the tillage blade speed and working depth according to the soil hardness, either the tillage efficiency is low, or the machine is damaged due to excessive load. In addition, manual adjustment of the tillage blade depth is not only cumbersome and time-consuming, but also difficult to ensure the accuracy and consistency of the adjustment. The root of these problems is that the existing micro-tillage machine lacks intelligent perception and adaptive adjustment functions, and cannot adjust the working parameters and its own status in real time according to the actual conditions of the soil, which greatly limits the application scope and operating efficiency of the micro-tillage machine, and it is difficult to meet the development needs of intelligent and efficient modern agriculture. Therefore, the present invention provides a tillage method, system and micro-tillage machine to solve the shortcomings of the existing technology. Summary of the Invention

The outer sides of the support plate 403 are fixedly connected to tooth plates 405, and the inner sides of the fixed frame 402 are fixedly connected to two telescopic rods 407. One end of the two telescopic rods 407 is fixedly connected to tooth plates 409. The outer side of tooth plates 409 fits with the outer side of tooth plates 405. The outer side of telescopic rods 407 is provided with a spring 408, one end of the spring 408 is fixedly connected to the inner side of the fixed frame 402, and the other end of the spring 408 is fixedly connected to the outer side of tooth plates 409. The outer side of the fixed frame 402 is fixedly connected to two pads 410, and the top of the pads 410 is equipped with a reducing The output end of the reduction motor 411 is fixedly connected to the winding roller 412, and the outer side of the winding roller 412 is fixedly connected to the pull rope 413. The top of the support plate 403 is fixedly connected to two U-shaped frames 414, and the other end of the pull rope 413 is fixedly connected to the outer side of the U-shaped frame 414. The tillage blade mechanism 5 includes two mounting plates 501, and the two mounting plates 501 are respectively fixedly connected to the outer sides of the micro-tillage machine body 1. The bottom of the mounting plate 501 is fixedly connected to the telescopic rod 2 502, and the bottom ends of the two telescopic rods 2 502 are rotatably connected to the rotating rod 503. The outer side of the rotating rod 503 is fixedly connected to multiple deep tillage blades 504. The interior of the micro-tillage machine body 1 is equipped with a servo motor 506. The servo motor 50 The output end of 6 is fixedly connected to a screw rod 507, the bottom of the micro-tillage machine body 1 is fixedly connected to a guide rod 508, the bottom of the guide rod 508 is fixedly connected to a connecting plate 511, the bottom of the screw rod 507 is rotatably connected to the top of the connecting plate 511, and a movable seat 509 is provided on the outside of the screw rod 507 and the guide rod 508. Two arc-shaped connecting rods 510 are fixedly connected to the outside of the movable seat 509, and the bottoms of the two arc-shaped connecting rods 510 are fixedly connected to the motor box 505. A dual-axis motor is installed inside the motor box 505, and the output end is fixedly connected to the rotating rod 503, and a protective plate 513 is fixedly connected to the outside of one of the arc-shaped connecting rods 510, and two side plates 512 are fixedly connected to the outside of the connecting plate 511.

[0046] Specifically, in the actual use scenario of the micro-tiller, the user first grasps the handle on the handheld frame 2, which provides a stable grip for operating the micro-tiller. The dual-axis motor inside the motor box 505 is started, and the powerful power output of the dual-axis motor drives the two rotating rods 503 to rotate at high speed. Since multiple deep tilling blades 504 are fixedly connected to the outside of the rotating rod 503, the rotation of the rotating rod 503 drives the deep tilling blades 504 to rotate synchronously. These high-speed rotating deep tilling blades 504 cut into the soil, crushing and plowing the soil, thereby enabling efficient cultivation of the land.

[0047] At the same time, the support plate 403 plays an important role. The bottom of the support plate 403 can be inserted into the soil for support, providing additional stability for the micro-tillage machine as a whole, making it less likely to shake or tilt during operation. High-precision soil moisture sensors are installed on both sides of the outside of the support plate 403. When the micro-tillage machine is operating, these sensors detect the soil moisture in real time and convert the detected data into electrical signals. The electrical signals are quickly transmitted to the two reduction motors 411. The reduction motors 411 that receive the signals start working and drive the winding roller 412 to rotate. As the winding roller 412 rotates, the pull rope 413 is gradually pulled and wound. 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 drives the support plate 403 to move downward.

[0048] As the support plate 403 moves downward, the ingenious design between tooth plate 1 405 and tooth plate 2 409 plays a key role. Tooth plate 1 405 is fixedly connected to the outer sides of the support plate 403, while tooth plate 2 409 is fixedly connected to the inner sides of the fixed frame 402 via two telescopic rods 1 407. The inclined surfaces between tooth plate 1 405 and tooth plate 2 409 fit together. When the support plate 403 is pulled downward by the pull rope 413, tooth plate 1 405 gradually descends along the inclined surface of tooth plate 2 409 and continuously staggers and engages with tooth plate 2 409. During this process, a spring 408, which is sheathed on the outside of telescopic rod 1 407, acts as a buffer and reset. 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 tooth plate 2 409. When tooth plate 1 405 moves downward, the spring 408 is compressed, storing elastic potential energy. The flat surface of tooth plate 2 409 acts as a limiter for tooth plate 1 405, ensuring that the downwardly moved support plate 403 maintains a stable position without any shaking or deviation. When the support plate 403 needs to be reset, the operator simply manually moves the two tooth plates 2 409 apart to distance them from tooth plate 1 405. At this time, the elastic potential energy of spring 408 allows the support plate 403 to easily move upward and return to its original position, facilitating subsequent adjustments.

[0049] When the tilling blade mechanism 5 is working, the pressure sensor responsible for detecting the hardness of the soil plays an important role. These pressure sensors are installed at the connection between the deep tilling blade 504 and the rotating rod 503 or other positions that can accurately sense the feedback force when the deep tilling blade 504 is working. When the deep tilling blade 504 is working in the soil, it is subjected to the reaction force of the soil. The pressure sensor can accurately detect the magnitude of this force and convert it into an electrical signal. According to the detected soil hardness data, the control system will automatically adjust the speed of the dual-axis motor in the motor box 505. For example, when it is detected that the soil hardness is relatively high, the control system will increase the speed of the dual-axis motor so that the deep tilling blade 504 can obtain greater cutting force to better crush the soil; when the soil hardness is relatively low, the speed of the dual-axis motor will be appropriately reduced to save energy and avoid damage to the soil structure caused by excessive tillage.

[0050] At the same time, the signal fed back by the pressure sensor will also start the servo motor 506. The output end of the servo motor 506 is fixedly connected to a screw rod 507, and the bottom of the micro-tillage machine body 1 is fixedly connected to a guide rod 508. A moving seat 509 is provided outside the screw rod 507 and the guide rod 508. When the servo motor 506 is started, it drives the screw rod 507 to rotate. Since the guide rod 508 guides the moving seat 509, the moving 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 outside of the moving seat 509, and the bottom of the two arc-shaped connecting rods 510 is fixedly connected to the motor box 505. Therefore, the up and down movement of the moving seat 509 drives the position adjustment of the overall tool assembly (including the motor box 505, the rotating rod 503, the deep plowing knife 504, etc.). When the soil is hard, the movable base 509 drives the cutting tool assembly downward, increasing the working depth of the deep tillage blade 504 to further break up the hard soil. When the soil is soft, the movable base 509 drives the cutting tool assembly upward, reducing the working depth and avoiding unnecessary energy consumption and soil disturbance. Through this intelligent adjustment method, the micro-tillage machine can automatically optimize tillage parameters according to different soil hardness conditions, improve tillage efficiency and quality, and better meet the actual needs of agricultural production.

[0051] Working principle: The user can hold the handle on the handheld frame 2 and start the dual-axis motor inside the motor box 505 to drive the two rotating rods 503 to rotate, so that the deep plowing knife 504 can be driven to rotate, and the land can be cultivated. The bottom of the support plate 403 can be inserted into the land for support. The sensor outside the support plate 403 can detect the soil humidity and transmit the electrical signal to the two reduction motors 411, thereby driving the winding roller 412 to rotate, and the pull rope 413 can be pulled for winding. The inclined surface between the tooth plate 1 405 and the tooth plate 2 409 fits together, so that the position of the tooth plate 1 405 can be gradually lowered and aligned with the tooth plate 2 409. By continuously staggering the engagement, the plane of the tooth plate 2 409 can limit it, so that the downward-moving support plate 403 can maintain a stable position. When the support plate 403 needs to be reset, the two tooth plates 2 409 can be pushed apart and distanced from the tooth plate 1 405, so that the support plate 403 can be easily moved up; in addition, the pressure sensor responsible for detecting the hardness of the soil can detect the hardness of the soil by the feedback force when the deep plowing knife 504 is working, thereby changing the speed of the dual-axis motor in the motor box 505, and starting the servo motor 506 to drive the screw rod 507 to rotate, so that the moving seat 509 can drive the position adjustment of the entire tool component, thereby changing the working depth.
