[0002] Deep plowing refers to the process of tilling a field before sowing or transplanting rice seedlings, turning over the deeper soil layers and covering them with the shallower ones. Deep plowing is the most basic and important tillage technique. It not only has the greatest impact on soil properties among tillage methods, but also has a wide range of effects and a much longer duration than other methods. Furthermore, other tillage methods such as harrowing and raking are based on deep plowing. Deep plowing has the functions of turning, loosening, mixing, and breaking up the soil, and proper deep plowing can significantly increase yields. Therefore, deep plowing is an agricultural activity that farmers highly value.

[0037] Example 1

[0038] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this embodiment provides a deep tillage mechanism for a deep tillage machine, including a frame 10 and a controller 20. The frame 10 is equipped with a rotary tillage blade holder 11, a first power unit 12 that drives the rotary tillage blade holder 11 to move up and down, and a detector 13 that detects the lifting depth of the rotary tillage blade holder 11. The rotary tillage blade holder 11 is equipped with a plurality of tillage blades 111, a linkage mechanism 112 that drives the tillage blades 111 to perform deep tillage operations, and a mudguard 113 disposed on the front end face of the rotary tillage blade holder 11. The horizontal plane at the lowest point of the rotary tillage blades 111 is higher than the horizontal plane at the lowest point of the mudguard 113. The input terminal of the controller 20 is electrically connected to the detector 13, and the first power unit 12 is electrically connected to the output terminal of the controller 20. The controller 20 can be a computer, or a PLC or chip, such as an S7-1200 PLC.

[0039] In this embodiment, the detector 13 can be an angle sensor, specifically an MPU-6050 angle sensor. Its working principle involves measuring the tilt angle of the rotary tiller 11 to determine the tillage depth, thereby controlling the first power unit 12 to adjust its height to achieve the desired tillage depth. Furthermore, the linkage mechanism 112 can be hydraulically driven or electrically driven to ensure that the tiller blades 111 can smoothly perform deep tillage operations.

[0040] During operation, the first power unit 12 drives the rotary tiller frame 11 to descend to the desired tillage depth. Simultaneously, the tillage blades 111 on the rotary tiller frame 11 are connected to the power source of the deep tiller via the linkage mechanism 112, causing the blades to rotate. Deep tillage is then performed by the movement of the deep tiller. During the movement of the deep tiller, uneven ground or varying hardness can easily cause the rotary tiller frame 11 to tilt. The detector 13 detects changes in the tilt angle of the rotary tiller frame 11. After receiving the signal of this tilt angle, the controller 20 adjusts the system by driving the first power unit 12 to ensure that the rotary tiller frame 11 remains within the set tillage depth. Through this intelligent adjustment mechanism, the deep tillage mechanism can automatically adapt to different field conditions, thereby improving tillage efficiency and quality.

[0041] Furthermore, the design of the mudguard 113 effectively reduces soil splashing. Simultaneously, the lowest point of the mudguard 113 is designed to be higher than the horizontal plane where the lowest point of the rotary tiller 111 is located, thus creating a height difference. This height difference can be manually designed, for example, 8cm, 10cm, 15cm, or 20cm, etc. This provides basic tillage depth data. Combined with the tilt angle information obtained from the angle sensor, the actual tillage depth of the rotary tiller 111 can be accurately calculated, achieving precise control and adjustment.

[0042] like Figure 1 and Figure 4 As shown, in this embodiment, a second power unit 14 is provided between the rotary tiller blade holder 11 and the frame 10 to drive the rotary tiller blade holder 11 to move horizontally. The second power unit 14 is electrically connected to the output terminal of the controller 20, and the second power unit 14 can be a hydraulic cylinder. Through the extension and retraction adjustment of the second power unit 14, the rotary tiller blade holder 11 can be adjusted horizontally to maintain its horizontal position and tillage depth. In practical applications, the hydraulic cylinder of the second power unit 14, through precise control, can respond to changes in ground undulations, ensuring consistent tillage.

[0043] Furthermore, in this embodiment, the rotary tiller 11 is provided with a first connecting arm 114 that is hinged to the ball joint of the frame 10, and a second connecting arm 115 for adjusting the sway of the rotary tiller 11 in conjunction with the second power unit 14. Utilizing the ball joint and socket hinge, 360° rotation is possible, accommodating the lifting and swaying movements required by the rotary tiller 11, ensuring flexible and stable connection. The first connecting arm 114 is made of a high-strength alloy material, such as alloy steel, possessing excellent tensile strength and corrosion resistance, ensuring no deformation during long-term use in complex farmland environments. The second connecting arm 115 is made of lightweight aluminum alloy, reducing overall weight and improving operational flexibility. Through this design, the rotary tiller 11 maintains a precise horizontal position under various terrain conditions, ensuring high efficiency in deep tillage operations.

[0044] like Figure 1 As shown, in this embodiment, there are two second connecting arms 115, and a connecting rod 116 is provided between the two second connecting arms 115. The second connecting arms 115 are arranged parallel to the first connecting arm 114. One end of the second connecting arm 115 is ball-jointed and hinged to the frame 10. The second power unit 14 is arranged between the other end of the second connecting arm 115 and the first connecting arm 114, or the second power unit 14 is arranged between the other end of the second connecting arm 115 and the rotary tiller holder 11.

[0045] Specifically, the stability of the rotary tiller 11 is enhanced through the coordinated action of the two second connecting arms 115. Simultaneously, the second power unit 14 drives the rotary tiller 11 to adjust its yaw, ensuring it remains horizontal for deep tillage. The connecting rod 116, designed like a lever, utilizes force transmission and balance to achieve precise control of the rotary tiller 11. Furthermore, the ball joint hinge design allows for flexible horizontal adjustment.

[0046] Furthermore, an adjusting rod 118 is provided between the second connecting arm 115 and the first connecting arm 114. The adjusting rod 118 is used for connection and support. The second power unit 14 is used for power adjustment, which reduces the cost and complexity of the design. Through this multi-unit collaborative adjustment mechanism, the rotary tiller 11 can achieve rapid and precise horizontal adjustment under different terrain and operating conditions, ensuring the efficiency of deep tillage operations and further improving the intelligence level of agricultural machinery.

[0047] like Figure 1 and Figure 2As shown, in this embodiment, the rotary tiller holder 11 is provided with a tiller rod 117 that drives all tillers 111 to rotate synchronously; the linkage mechanism 112 includes a universal joint 1121 connected to the power source, a transmission rod 1122 linked to the universal joint 1121, and a linkage member 1123 connecting the transmission rod 1122 and the tiller rod 117. The transmission rod 1122 is provided on the top surface of the rotary tiller holder 11, and the linkage member 1123 is provided on one side surface of the rotary tiller holder 11.

[0048] In this embodiment, the universal joint 1121 enables flexible connection and transmission to cope with the complex frame structure 10, allowing for power transmission in the tilting direction, thereby achieving synchronous rotation of the tillage blades 111. Specifically, the universal joint 1121 and the transmission rod 1122 can be connected by a gear structure, which in turn drives the tillage blade rod 117 to rotate through the linkage 1123, causing the tillage blades 111 on the tillage blade rod 117 to rotate, achieving the purpose of deep tillage of the ground.

[0049] Furthermore, two transmission rods 1122 are provided, symmetrically arranged on the top surface of the rotary tiller holder 11; two linkage components 1123 are provided, one linkage component 1123 is located between one transmission rod 1122 and one end of the tiller rod 117, and the other linkage component 1123 is located between the other transmission rod 1122 and the other end of the tiller rod 117. This achieves synchronous driving of both ends of the tiller rod 117, ensuring the consistency and stability of the tiller 111's rotation. The transmission of the two transmission rods 1122 can be linked using a helical gear pair structure (i.e., the end of the universal joint 1121 has a helical gear, and the transmission rod 1122 also has a helical gear for meshing). The two sensors, arranged symmetrically in this way, can be driven synchronously.

[0050] Specifically, in this embodiment, the linkage 1123 is a sprocket and chain structure, a belt and pulley structure, or a gear structure. This allows for flexible design based on requirements. For example, a gear structure can be selected when a large and stable transmission force is needed; if flexible adjustment is required, a sprocket and chain or belt and pulley structure can be selected to meet different operational needs. Through this multi-structure linkage design, the rotary tiller 11 can maintain efficient and stable operating performance in complex terrain, further improving the adaptability and reliability of agricultural machinery.

[0051] like Figure 3 As shown, in this embodiment, at least one support foot 15 is provided on the side of the rotary tiller 11 opposite to the mudguard 113. In this way, after the rotary tiller 11 is disassembled, it can be supported at both ends by the mudguard 113 and the support foot 15 to prevent the rotary tiller 11 from tipping over. At the same time, it can prevent the rotary tiller blades 111 from contacting the ground, reducing wear or bending (e.g. on a cement ground), thus forming a protective effect on the tiller blades 111.

[0052] like Figure 4 and Figure 5 As shown, in this embodiment, an adjusting rod 118 is hinged to the upper shaft of the mudguard 113. The middle part of the adjusting rod 118 is provided with a plurality of adjusting holes 1181 spaced apart along the axial direction. The rotary tiller 11 is provided with a hinge block 119 that is hinged to the adjusting holes 1181. A first spring 120 is provided on the rod segment between the two hinge points of the adjusting rod 118, and a second spring 121 is provided on the rod segment of the adjusting rod 118 extending toward the rotary tiller 11.

[0053] Specifically, by cooperating with the hinge block 119 through different adjustment holes 1181 on the adjusting rod 118, the height of the mudguard 113 can be adjusted to accommodate different depth requirements of rotary tillage operations. Simultaneously, the mudguard 113 can be used to level the tilled soil. The design of the first spring 120 and the second spring 121 provides good shock absorption, and the first spring 120 and the second spring 121 provide elastic force to push and reset the mudguard 113, ensuring smooth and buffered operation during lifting and resetting, reducing mechanical impact and wear. Furthermore, through the combination of the adjusting rod 118 and the hinge block 119, users can quickly adjust the position and angle of the mudguard 113 according to actual operational needs, further improving operational quality and efficiency.

[0054] Example 2

[0055] This embodiment provides a deep tillage machine, including a deep tillage mechanism as described in Embodiment 1. By adjusting the height of the rotary tiller blades, precise tillage depth is achieved. Furthermore, the depth of the rotary tiller blades is automatically adjusted based on real-time feedback from an angle sensor to meet the tillage depth requirements of different fields. Simultaneously, mudguards effectively level the tilled soil, ensuring land uniformity. Through this series of precise adjustment mechanisms, the agricultural machinery not only achieves depth adjustment but also significantly improves operational flexibility and adaptability, resulting in optimized tillage performance.

[0056] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
