Description

Technical Field

[0001] This application relates to the field of soil improvement technology, specifically a device for improving saline-alkali land soil. Background Technology

[0002] Saline-alkali land is a widespread land degradation problem worldwide, which seriously restricts agricultural production and the ecological environment. The formation of saline-alkali land is mainly due to high groundwater levels, strong evaporation, and salt accumulation on the surface as water rises, leading to the deterioration of soil physical and chemical properties and hindering crop growth.

[0003] Currently, saline-alkali land improvement technologies mainly include methods such as water conservancy engineering improvement, chemical improvement, biological improvement, and physical improvement.

[0004] Existing methods for treating saline-alkali land suffer from problems such as unsustainable improvement effects, complex operation, and secondary pollution. To address these issues, a soil improvement device for saline-alkali land is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a soil improvement device for saline-alkali land, which integrates deep loosening, rinsing, and mulching to significantly improve the efficiency of saline-alkali land improvement. It is also simple to operate and can effectively avoid the problem of secondary pollution.

[0006] To achieve the above objectives, this application provides the following technical solution: a soil improvement device for saline-alkali land, comprising a frame, a deep tillage mechanism, a rinsing mechanism, and a mulching mechanism. The deep tillage mechanism includes a hydraulic cylinder fixedly connected to the upper surface of the frame. A rubber connector is fixedly connected to the output shaft end of the hydraulic cylinder. A deep tillage shovel is fixedly connected to the bottom end of the rubber connector. A vibrator is installed on the top of the back of the deep tillage shovel.

[0007] The rinsing mechanism includes a water tank fixedly connected to the upper surface of the frame. Water pumps are installed on both sides of the water tank. The output end of each water pump is connected to a liquid delivery pipe. Spray heads are fixedly connected to the bottom surface of the frame. The output ends of the two liquid delivery pipes are respectively connected to the two sides of the spray heads.

[0008] The mulching mechanism includes multiple hay bins fixedly connected to the upper surface of the frame and a guide channel fixedly connected to the bottom surface of the frame. Each hay bin has a spiral feeding blade at its bottom. The bottom surface of the guide channel is fixedly connected to a number of third servo motors corresponding to the spiral feeding blades. The output end of the third servo motor is fixedly connected to the shaft end of the spiral feeding blade. A rubber pressing roller is installed at the end of the frame. The outer surface of the rubber pressing roller has a wavy pattern.

[0009] Through the above scheme, the hydraulic cylinder drives the deep loosening shovel into the soil via the rubber connector, and the vibrator breaks the soil at a certain frequency, effectively cutting off the salt capillaries and improving soil permeability, thus promoting the subsequent leaching effect. The water tank supplies water to the spray head through the water pump and the delivery pipe, and then the spray head delivers the spraying agent to the broken saline-alkali soil, thereby improving the salt leaching efficiency. The second servo motor drives the crushing rod to crush the grass, and the spiral feeding blades deliver the grass evenly through the guide groove. The corrugated pattern on the surface of the rubber grass pressing roller compacts the covering layer, which can evenly cover the surface of the leached soil with grass, inhibiting evaporation and salt rise. This realizes the integrated operation of deep loosening, leaching and covering, which significantly improves the efficiency of saline-alkali land improvement. Multiple improvement processes can be completed in a single operation. Moreover, it adopts a combination of physical and biological improvement methods to avoid the pollution problems of chemical amendments, and has excellent environmental performance. In addition, the device is easy to operate and is suitable for large-scale promotion and use.

[0010] Furthermore, guide posts are fixedly connected to both sides of the upper surface of the rubber connector, and the two guide posts are slidably sleeved on both sides of the frame.

[0011] The above-mentioned design allows the guide posts to make the submerged shovel more stable when moving up and down.

[0012] Furthermore, each segment of the infusion tube is equipped with a one-way valve, and the top of the water tank is equipped with two feed inlets.

[0013] The above-mentioned solution allows the one-way valve to prevent the spraying agent inside the spray head from being drawn back into the infusion pipe, thus improving the safety of the spraying process. The feed inlet allows for easy addition of spraying agent raw materials to the water tank, facilitating subsequent spraying operations.

[0014] Furthermore, the inner wall of the water tank is rotatably fitted with two stirring rods, each stirring rod having a stirring blade fixedly connected to its outer surface, and each stirring rod having a sprocket fixedly connected to its top.

[0015] The above method allows the stirring rod to rotate, which in turn drives the stirring blades to rotate. The rotation of the stirring blades enables the spraying agent inside the water tank to be mixed more thoroughly, thereby optimizing the improvement effect on saline-alkali soil.

[0016] Furthermore, a chain and a first servo motor are provided above the water tank. The two sprockets are connected by chain drive. The first servo motor is fixedly connected to the upper surface of the water tank. The output shaft end of the first servo motor is fixedly connected to the top end of the corresponding stirring rod.

[0017] With the above scheme, when the first servo motor starts, it will drive the corresponding sprocket to rotate through the corresponding stirring rod. Then, with the help of the set chain, the stirring rod and sprocket on the other side can be rotated, which in turn can drive the rotation of multiple stirring blades.

[0018] Furthermore, a second servo motor is fixedly connected to the upper surface of each of the forage bins, a crushing rod is fixedly connected to the output shaft end of each of the second servo motors, crushing blades are fixedly connected to the outer surface of each of the crushing rods, and a feeding port is installed on the top of each forage bin.

[0019] With the above scheme, when the second servo motor starts, it will drive the corresponding crushing rod and crushing blade to rotate, thereby further crushing the grass inside the grass box, which is beneficial to the uniform coverage of the grass in the subsequent work. The grass can be easily put into the grass box for use through the set feeding port.

[0020] Furthermore, a main controller is fixedly connected to the upper surface of the frame, and the electrical components inside the deep loosening mechanism, the rinsing mechanism, and the mulching mechanism are all electrically connected to the main controller.

[0021] The above-mentioned scheme allows the central controller to easily control the electrical components inside the deep loosening mechanism, rinsing mechanism, and mulching mechanism, simplifying the operation process and making it more practical.

[0022] Furthermore, a traction assembly is fixedly connected to the front end of the frame, and two wheels are installed on the bottom surface of the frame.

[0023] The above scheme allows for a convenient and stable connection between the device and the tractor, while the included wheels enable the device to be moved more stably by the tractor, which is beneficial for the improvement of saline-alkali soil.

[0024] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0025] This saline-alkali soil improvement device uses a hydraulic cylinder to drive a deep-loosening shovel into the soil via a rubber connector. A vibrator breaks the soil at a certain frequency, effectively cutting off salt capillaries and improving soil permeability, thus promoting subsequent leaching. A water tank supplies water to the spray head via a water pump and delivery pipe. The stirring rod and stirring blades, linked by a sprocket and chain, evenly mix the spraying agent, improving salt leaching efficiency. A second servo motor drives a crushing rod to pulverize the straw. Spiral feeding blades evenly convey the straw through a guide channel. The corrugated surface of the rubber straw pressing roller compacts the covering layer, evenly covering the leached soil surface with straw, inhibiting evaporation and salt rise. This device integrates deep loosening, leaching, and straw covering, significantly improving the efficiency of saline-alkali soil improvement. Multiple improvement processes can be completed in a single operation. Furthermore, it uses a combination of physical and biological improvement methods, avoiding the pollution problems of chemical amendments, and has excellent environmental performance. In addition, the device is easy to operate and suitable for large-scale promotion and use. Attached Figure Description

A vibrator 204 breaks the soil at a certain frequency, effectively cutting off salt capillaries and improving soil permeability, thus promoting subsequent leaching. A water tank 301 supplies water to a spray head 305 via a water pump 302 and a delivery pipe 303. A stirring rod 307 and stirring blades 308 uniformly mix the spraying agent under the linkage of a sprocket 309 and a chain 310, improving the salt leaching efficiency. A second servo motor 402 drives a crushing rod 403 and a powder... The shredded grass is evenly conveyed by the spiral feeding blades 407 through the guide channel 405, and the corrugated surface of the rubber grass pressing roller 408 compacts the covering layer, which can evenly cover the grass on the surface of the leached soil, inhibiting evaporation and salt rise.

Multiple improvement processes can be completed in a single operation. Moreover, it adopts a combination of physical and biological improvement methods to avoid the pollution problems of chemical amendments, and has excellent environmental protection performance. In addition, the device is easy to operate and is suitable for large-scale promotion and use.

[0038] The working principle of the above embodiment is as follows: This device is connected to the tractor through the traction component 6, and is driven by the walking wheels 7 and the rubber straw pressing roller 408. During operation, the deep loosening mechanism 2 starts first. The hydraulic cylinder 201 drives the deep loosening shovel 203 to cut into the saline-alkali soil to a certain depth through the rubber connector 202. The vibrator 204 vibrates at a certain frequency to break up the soil clods and cut off the capillary upward channel of salt. The guide column 205 ensures the stability of the deep loosening trajectory. Then, the rinsing mechanism 3 works synchronously. The improvement liquid in the water tank 301 is pressurized by the water pump 302 and then transported to the spray head 305 through the infusion pipe 303. The one-way valve 304 prevents the liquid from flowing back. When the first servo motor 311 starts, the stirring rod 307 will drive the stirring blade 308 to fully mix the corrosion in the water tank 301 under the linkage of the sprocket 309 and the chain 310. Amendments such as hygroscopic acid enhance the efficiency of the leaching solution in dissolving salts. After leaching, the mulching mechanism 4 is activated. The second servo motor 402 drives the crushing rod 403 and crushing blades 404 to further crush the forage. The spiral feeding blades 407 spread the forage evenly on the soil surface through the guide groove 405. The rubber pressing roller 408 uses the surface wave pattern to compact the forage to a certain thickness, forming a continuous covering layer to inhibit evaporation and salt migration. The main controller 5 centrally controls the start and stop of the hydraulic, leaching and mulching systems and parameter matching to ensure coordinated operation of each link. This device integrates deep loosening and salt suppression, leaching and desalination, and mulching and salt fixation. It can complete soil structure improvement and salt control in a single operation. It is highly efficient, environmentally friendly, free of chemical pollution, and durable. It is suitable for large-scale treatment of saline-alkali land in arid areas.
