[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1

[0028] Please see Figure 1-10 The soil loosening and compaction equipment after wheat straw is returned to the field includes a bracket 1, and an adjustable compaction mechanism 2 is provided on the outside of the bracket 1. The adjustable compaction mechanism 2 includes a crushing frame 201, and a pressing frame 216 is movably hinged to the crushing frame 201 through two sets of movable frames 218. Two movable frames 210 are fixedly connected to the outer surface of the crushing frame 201 and the outer surface of the pressing frame 216. A sliding groove 215 is opened on the inner wall of each movable frame 210. A lead screw 212 is rotatably connected inside each sliding groove 215. A slider 211 is threadedly connected to the outer surface of each lead screw 212. The outer surface of each slider 211 is slidably connected to the inside of the sliding groove 215.

[0029] Each movable frame 210 has a drive motor 214 fixedly connected to its inner wall. The outer surface of the power output end of each drive motor 214 is connected to the outer surface of the top end of the lead screw 212 via a coupling 213. A set of sliders 211 are fixedly connected to a blade holder 209 on their adjacent sides. A dual-axis servo motor 208 is located below the crushing frame 201. Another set of sliders 211 are rotatably connected to a pressure plate 217 on their adjacent sides. A bracket 204 is fixedly connected to the upper surface of the crushing frame 201. A hydraulic cylinder 202 is hinged to the outer surface of the bracket 204. A connecting frame 205 is hinged to the telescopic end of the bracket 204. The bottom surface of the connecting frame 205 is fixedly connected to the upper surface of the pressure plate 216. A controller body 203 is fixedly connected to the outer surface of the bracket 204. A telescopic rod 207 is fixedly connected to the bottom surface of the crushing frame 201. A soil temperature and humidity sensor 206 is fixedly connected to the telescopic end of the telescopic rod 207. The 206 typically consists of a probe, a sensing unit, a signal processing circuit, and a signal output interface. Its working principle is as follows: the sensor directly contacts the soil being measured via a metal probe. Moisture measurement is primarily based on the frequency domain reflection (FDR) principle, where the sensor generates an electromagnetic wave of a specific frequency. As this electromagnetic wave propagates through the soil medium surrounding the probe, its propagation characteristics change due to variations in the soil's dielectric constant. Since the soil's dielectric constant is closely related to its moisture content, the volumetric water content of the soil can be determined by measuring the change in this electromagnetic signal. Temperature measurement typically utilizes a built-in thermistor or semiconductor temperature sensing element. The temperature value is obtained by sensing changes in the thermistor's resistance or electrical properties as the soil temperature changes. Finally, the analog signal collected by the sensing unit is processed and converted by the internal circuitry, outputting a standard digital or analog signal for reading by devices such as the controller body 203 in this invention, thereby achieving real-time and accurate monitoring of soil moisture.

[0030] Example 2

[0031] Please see Figure 1-10 The bracket 1 is hinged to the crusher 201 via two sets of movable frames 218. The output end of the dual-axis servo motor 208 is fixedly connected to one end of each of the two blade holders 209 that are close to each other. A connecting plate 3 is fixedly connected to the upper surface of the bracket 1. The connecting plate 3 is used to connect to the traction equipment.

[0032] Each tool holder 209 has a bearing 4 fixedly connected to its outer surface, and the outer surface of each bearing 4 is fixedly connected to the outer surface of the slider 211, ensuring stable rotation of the tool holder 209.

[0033] A fixing frame 6 is fixedly connected to the outer surface of the controller body 203. The outer surface of the fixing frame 6 is fixedly connected to the outer surface of the bracket 204, which enhances the stability of the controller body 203. The controller consists of two parts: hardware and software. The hardware mainly includes a central processing unit (CPU) for calculation, input / output (I / O) interfaces for connecting sensors and actuators, memory for storing programs and data, as well as power supply and communication modules. The software includes control algorithm programs, real-time operating systems such as RTOS, and human-machine interfaces, all working together to ensure accuracy. Highly efficient system control is widely used in industrial automation, smart homes, automotive electronics, and other fields. A controller is a core device that regulates system operation by processing input signals in real time and generating control commands. Its working principle can be summarized as follows: First, it collects signals from sensors or external inputs, such as temperature and speed, and compares them with preset target values ​​to calculate the deviation. Then, it uses built-in algorithms such as PID control and logical judgment to analyze the deviation and generate adjustment commands. Finally, it drives actuators such as motors and valves through the output interface to adjust the system state. At the same time, it continuously monitors the effect through closed-loop feedback to achieve dynamic stability. The controller can control the electrical components of this technical solution.

[0034] A fixing frame 5 is fixedly connected to the outer surface of the telescopic rod 207. The upper surface of the fixing frame 5 is fixedly connected to the bottom surface of the crushing rack 201, thereby improving the support strength of the telescopic rod 207.

[0035] A stabilizing plate 7 is fixedly connected to the outer surface of the dual-axis servo motor 208. The upper surface of the stabilizing plate 7 is fixedly connected to the bottom surface of the crushing rack 201, further reinforcing the dual-axis servo motor 208.

[0036] Example 3

[0037] The working principle of this utility model is as follows: During use, the equipment is connected to a traction device, such as a tractor, via a connecting plate 3. During the movement of the equipment, the soil temperature and humidity sensor 206 detects the soil moisture in real time and transmits the data to the controller body 203. The controller body 203 controls the extension and retraction of the hydraulic cylinder 202 according to the preset humidity threshold. The angle of the pressing frame 216 is adjusted through the connecting frame 205, thereby changing the compaction intensity of the pressing burr 217 on the soil. At the same time, the drive motor 214 drives the lead screw 212 to rotate through the coupling 213, causing the slider 211 to move in the slide groove 215, adjusting the longitudinal height position of the cutter holder 209 and the pressing burr 217 to adapt to the soil operation requirements of different humidity and different lengths and densities of wheat straw. The dual-axis servo motor 208 drives the cutter holder 209 to rotate at high speed to crush the straw. Throughout the process, the equipment automatically adjusts the compaction and crushing parameters according to the soil conditions to ensure that the soil is loose and the compaction effect is uniform, thereby improving the quality of land preparation.

[0038] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
