[0002] Saline-alkali land refers to land containing excessive soluble salts. The cause of soil salinization is that the salt content of the soil and groundwater is too high. Under strong surface evaporation, shallow groundwater reaches the surface through the gaps between soil particles and evaporates. After the water evaporates, the salt in the water is released and accumulates on the soil surface, causing soil salinization. Most of the saline-alkali land improvement equipment currently used involves deep plowing to improve the saline-alkali land and make it easier to grow crops.

[0003] However, deep tillage operations in saline-alkali land currently face significant resistance, with severe soil sticking to the tillage shovel. Existing vibratory deep tillage machines suffer from low vibration frequency, unstable vibration, poor deep tillage stability, and poor soil breaking effect, which affects subsequent cultivation. There is a lack of vibratory deep tillage machinery suitable for saline-alkali land.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The following embodiments involve saline-alkali land and servo motors. Saline-alkali land refers to soil containing excessive soluble salts (such as sodium chloride, sodium sulfate, sodium carbonate, etc.), and its soil pH value is usually high, exhibiting alkalinity or strong alkalinity. Due to the excessively high salt content of the soil and groundwater, under strong surface evaporation, shallow groundwater rises to the surface through the gaps between soil particles and evaporates. The salt in the water precipitates out and accumulates in the soil surface layer, ultimately leading to soil salinization. Saline-alkali land inhibits water absorption by crop roots, resulting in poor plant growth and reduced yield. At the same time, the high-salt environment damages soil structure, causing soil compaction and hardening, further exacerbating the difficulty of cultivation. The deep tillage machine provided by this utility model is designed for the high resistance and compaction characteristics of saline-alkali land. It improves soil structure and reduces salt content through vibration deep tillage and soil breaking operations, creating conditions for subsequent cultivation.

[0026] A servo motor is a high-precision automated drive motor, belonging to the actuators of a closed-loop control system. Its characteristics include the ability to precisely control speed, position, and torque based on input signals, and the presence of a feedback mechanism (such as an encoder) that can feed back the operating status to the controller in real time, achieving precise adjustment. The servo motor receives electrical signals (such as pulse signals) to drive the rotor to rotate, and the encoder monitors the rotor position in real time, feeding the data back to the driver to form a closed-loop control, ensuring output accuracy.

[0027] A reversible motor is a type of motor that can alternate between forward and reverse rotation via a control circuit, belonging to the category of open-loop or closed-loop control motors. Compared to ordinary motors, its rotor structure and commutation mechanism design allow the motor to switch directions without stopping, and the operating state remains stable during direction switching. Reversible motors typically achieve direction switching by changing the direction of the current in the stator windings (e.g., changing the phase sequence in an AC motor, or changing the armature voltage polarity in a DC motor). Some reversible motors are equipped with mechanical commutators or electronic commutation circuits to ensure reliability during direction switching.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figures 1 to 4As shown, this utility model provides an in-situ deep tillage machine for saline-alkali land, including: a frame 1; a vibrating frame 4, which is located above the frame 1, with a buffer and a driving component installed between the vibrating frame 4 and the frame 1. The vibrating frame 4 generates intermittent vibration under the drive of the driving component, so that the deep tillage shovel 3 installed on the vibrating frame 4 performs deep tillage on the saline-alkali land; the driving component includes a first motor 11, a half gear 13, a rack 14, and a movable column 15. The rack 14 is fixedly connected to one side of the movable column 15, the half gear 13 meshes with the rack 14, the half gear 13 is installed on the first motor 11, the first motor 11 is installed on the frame 1, the top of the movable column 15 is fixedly installed on the vibrating frame 4, and the bottom of the movable column 15 extends to the bottom of the frame 1; and a soil crushing component, which is installed at the end of the frame 1 and is used to crush hard soil clods in the saline-alkali land.

[0030] The frame 1 serves as the basic support structure for the entire equipment. The front end of the frame 1 is fixedly connected to the suspension frame 2, which is used to install the frame 1 on agricultural equipment, such as a tractor, to facilitate the movement and operation of the equipment. The end of the frame 1 is equipped with a soil-crushing frame 18 via an electric telescopic rod 17. Wheels 21 are installed on both sides of the frame 1 to assist in the movement of the equipment.

[0031] The vibrating frame 4 is located above the frame 1. A buffer and a driving component are installed between the vibrating frame 4 and the frame 1. The vibrating frame 4 vibrates intermittently under the drive of the driving component, thereby enabling the deep loosening shovel 3 mounted on the vibrating frame 4 to deep loosen the saline-alkali land. A fixing plate 8 is fixedly connected to the frame 1, and a connecting plate 9 is fixedly connected to the vibrating frame 4.

[0032] The driving components include a first motor 11, a half gear 13, a rack 14, and a movable column 15. The rack 14 is fixedly connected to one side of the movable column 15 and meshes with the teeth of the half gear 13. One end of the shaft of the half gear 13 is installed on the output end of the first motor 11, and the other end is rotatably installed on the support plate 12. The support plate 12 is fixedly connected to the fixed plate 8. The first motor 11 is a servo motor that can run in both forward and reverse directions, but it is not limited to a servo motor and can also be other motors that can run in both forward and reverse directions. The first motor 11 is fixedly installed on the fixed plate 8 of the frame 1. The top of the movable column 15 is fixedly connected to the connecting plate 9 of the vibration frame 4, and the bottom extends to the bottom of the frame 1. A limit plate 16 is fixedly connected to the bottom of the movable column 15 to prevent the movable column 15 from falling off the frame 1. The frame 1 has a through hole 10 on the fixed plate 8. The movable column 15 and the rack 14 extend through the through hole 10 to the bottom of the fixed plate 8. The size of the limiting plate 16 is larger than the diameter of the through hole 10, which can prevent the movable column 15 from detaching from the fixed plate 8 when it moves upward.

[0033] The buffer is a spring 5, one end of which is fixedly connected to the frame 1 and the other end is fixedly connected to the vibration frame 4. It is used to buffer the impact force when the vibration frame 4 vibrates and ensure the stability of the vibration frame 4.

[0034] The first motor 11 drives the half gear 13 to rotate alternately in both directions, which in turn drives the rack 14 and the movable column 15 to move up and down, thus realizing the intermittent vibration of the vibrating frame 4. This allows the subsoil shovel 3 to perform intermittent deep tillage on the saline-alkali land, effectively reducing the resistance of the subsoil operation and minimizing soil sticking. At the same time, the spring 5 buffer ensures the stability of the vibrating frame 4 during vibration, improving the stability and reliability of the subsoil operation.

[0035] The deep loosening shovel 3 is mounted on the vibrating frame 4, and a shovel base 6 is welded onto the vibrating frame 4. The deep loosening shovel 3 includes a shovel handle 301 and a shovel tip 302. The shovel handle 301 and the shovel tip 302 are integrally formed to ensure the stability of the deep loosening shovel 3. Several positioning holes 303 are opened on the shovel handle 301, and bolt holes 7 of the same size are also opened on the shovel base 6. The shovel handle 301 is fixedly mounted on the shovel base 6 through the positioning holes 303 and the bolts 7, and is fixed with nuts. The installation depth of the deep loosening shovel 3 can be adjusted through the positioning holes 303, thereby changing the deep loosening depth of the shovel tip 302 to adapt to the deep loosening needs of different saline-alkali lands.

[0036] The soil crushing component is installed on the soil crushing frame 18 at the end of the frame 1. It is used to crush hard soil clods in saline-alkali land. The soil crushing component includes a soil crushing roller 19 and a second motor 20. One end of the soil crushing roller 19 is rotatably mounted on the soil crushing frame 18, and the other end passes through the soil crushing frame 18 and is mounted on the output end of the second motor 20. The second motor 20 is fixedly mounted on the soil crushing frame 18. When it is necessary to crush hard soil clods, the electric telescopic rod 17 is adjusted to move the soil crushing frame 18 downward, which facilitates the crushing roller 19 to crush the hard soil clods. The electric telescopic rod 17 can flexibly adjust the crushing depth of the soil crushing roller 19 to adapt to different soil conditions and improve the effect of soil improvement in saline-alkali land. After deep loosening, the soil crushing component at the end of the frame 1 crushes the hard soil clods in the soil, further improves the soil structure, and provides good soil conditions for subsequent tillage.

[0037] Working Principle: When the equipment performs deep loosening operations on saline-alkali land, the first motor 11 starts. Its forward rotation drives the half-gear 13 to rotate, which meshes with the rack 14, pushing the rack 14 and the movable column 15 downwards. The movable column 15 then drives the vibrating frame 4 and the deep loosening shovel 3 downwards, inserting the shovel 3 into the saline-alkali land for deep loosening. When the first motor 11 reverses direction, the half-gear 13 rotates in the opposite direction, meshing with the rack 14 and driving the movable column 15 upwards, pulling the deep loosening shovel 3 out of the soil. Through the alternating forward and reverse operation of the first motor 11, the deep loosening shovel 3 intermittently moves up and down, repeatedly loosening the saline-alkali land. During this process, the spring 5 buffers the vibration of the vibrating frame 4, ensuring the stability of the deep loosening operation.

[0038] After the deep tillage operation is completed, the second motor 20 is started to drive the soil crushing roller 19 to rotate. At the same time, the height of the soil crushing frame 18 is adjusted by the electric telescopic rod 17 so that the soil crushing roller 19 can crush the hard soil clods in the deep tillage soil and further improve the soil structure.
