Description

Technical Field

[0001] This utility model relates to the field of soil remediation technology, specifically to a device for remediating severely saline-alkali soil. Background Technology

[0002] In saline-alkali soils, salt ions disrupt the aggregate structure between soil particles, causing them to disperse and making the soil prone to compaction. Compacted soil exhibits further deterioration in aeration and permeability, hindering the growth and development of plant roots. Roots struggle to penetrate the compacted layer, impairing the absorption of water and nutrients by plants.

[0003] Saline-alkali land can be improved by applying chemical amendments. Common chemical amendments include gypsum, phosphogypsum, sulfur, and ferrous sulfate. For example, calcium ions in gypsum can replace sodium ions on soil colloids, reducing soil alkalinity. At the same time, sulfate ions can combine with some cations in the soil to form soluble salts, which are then excreted with water, thereby reducing soil salinity.

[0004] A soil remediation tillage device, application number CN202410395817.7, includes: an outer frame; a remediation component screwed onto the back of the inner side of the outer frame; a tillage box installed on the front of the inner side of the outer frame; a central column disposed inside the tillage box; a hollow column II inserted into the central column; the hollow column II screwed onto the central column; and several rectangular holes evenly spaced on the circumference of the hollow column II. By using the remediation component and the tillage box, small mounds of soil can be removed, excess soil on the ground enters the tillage box, and the remaining part of the ground is flattened by the remediation component. The remediation component uses a power transmission component to drive the hollow column II to rotate, which in turn drives a soil-lifting component to rotate. The soil-lifting component can lift clumps of soil in the tillage box, fully disperse the clumps, and break them into smaller particles upon landing, making them easier to remediate, saving labor costs, and improving remediation efficiency.

[0005] The aforementioned patent uses a soil-turning component to lift clumps of soil. However, in saline-alkali soils, the presence of a large amount of sodium ions in the inner soil layer causes soil particles to disperse, making it difficult to form a good aggregate structure. This results in poor soil aeration and permeability. When dry, the soil tends to harden and compact, forming a hard surface layer that hinders root penetration and growth. When wet, it becomes sticky and muddy, further reducing aeration and affecting root respiration, making it difficult for the remediation device to move on the soil surface.

[0006] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0007] The purpose of this invention is to provide a device for remediating severely saline-alkali soil that can effectively solve the above-mentioned technical problems.

[0008] To achieve the purpose of this utility model, the following technical solution is adopted:

[0012] The roller includes a hub and a spiral blade disposed inside the hub. A gear is provided on the inner side of the hub, and a third gear is connected to the gear inside the hub via a chain.

[0013] Furthermore, the liquid dispensing assembly consists of an air bladder, a liquid storage tank, and a liquid dispensing valve; the air bladder is connected to the liquid storage tank, and the liquid storage tank is connected to the liquid dispensing valve.

[0014] Furthermore, the soil-turning assembly consists of a frame and soil-turning claws; the frame is fixedly connected to the soil-turning claws, and the side of the soil-turning claws is provided with a baffle that is fixedly connected to the frame.

[0015] Furthermore, the first gear and the third gear have the same diameter, and the second gear has a larger diameter than the other two sets of gears.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention is a device for remediating severely saline-alkali soil. When the hub rotates, the cone pierces the soil surface and penetrates the compacted soil, making the soil structure loose, which is easy to turn over and inject the solution. When piercing the soil, the saline soil at the bottom of the saline-alkali land is exposed, making it easy for the hub to sink into the soil. After the hub body is submerged in the soil, the spiral blades rotate with the hub, further breaking up the soil to achieve a better soil breaking effect. Attached Figure Description

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0027] like Figures 1 to 6 As shown, a device for remediating severely saline-alkali soil includes: a drive assembly 1, a transmission assembly 2, a liquid discharge assembly 3, a soil turning assembly 4, and rollers 5.

[0028] In saline-alkali soils, salt ions disrupt the aggregate structure between soil particles, causing them to disperse and making the soil prone to compaction. Compacted soil exhibits further deterioration in aeration and permeability, hindering the growth and development of plant roots. Roots struggle to penetrate the compacted layer, impairing the absorption of water and nutrients by plants.

[0029] The device is driven by a drive assembly 1, which includes a housing 11, a gearbox 12 installed inside the housing 11, and a drive motor 13 serving as the power source for the gearbox 12. The output end of the drive motor 13 is fixedly connected to the input end of the gearbox 12, and a first gear 14 is fixedly installed on the output end of the gearbox 12. The drive motor 13 outputs power to the gearbox 12, and the gearbox 12 drives the first gear 14 to rotate.

[0030] The transmission assembly 2 consists of a frame 4121, a rotating rod 22 rotatably mounted on the frame 4121, a second gear 23 fixedly mounted on the rotating rod 22, a third gear 24 fixedly mounted on the rotating rod 22, and a push block 25 fixedly mounted on the rotating rod 22. When the first gear 14 rotates with the transmission 12, the second gear 23 is connected to the first gear 14 via a chain. The second gear 23 rotates with the first gear 14, and at the same time, the second gear 23 drives the rotating rod 22 to rotate on the frame 4121, so that the rotating rod 22 drives the third gear 24 to rotate. At the same time, the push block 25 fixed on the surface of the rotating rod 22 also rotates with the rotating rod 22 to drive the liquid dispensing assembly 3 and the roller 5.

[0031] As a supplement: the diameters of the first gear 14 and the third gear 24 are equal, and the diameter of the second gear 23 is larger than that of the other two sets of gears; when the first gear 14 drives the second gear 23 and the third gear 24 to rotate, the rotation speed of the second gear 23 will be lower than that of the other two sets of gears, so as to keep the rotating rod 22 rotating at a low speed on the frame 4121, so as to prevent the liquid dispensing component 3 from dispensing too quickly, resulting in excessive spraying of repair medicine in the same area of ​​saline-alkali land.

[0032] The liquid dispensing assembly 3 consists of an airbag 31, a storage tank 32, and a dispensing valve 33. The airbag 31 is connected to the storage tank 32, and the storage tank 32 is connected to the dispensing valve 33. The storage tank 32 stores chemical agents for remediating saline-alkali land. The airbag 31 is placed on top of the storage tank 32. When the rotating rod 22 rotates, it drives the push block 25 to rotate. When the push block 25 rotates, it intermittently squeezes the airbag 31. At the same time, the airbag 31 is equipped with a pressure sensor, and the airbag 31 is electrically connected to the dispensing valve 33. When the push block 25 squeezes the airbag 31, it triggers the pressure sensor, and the dispensing valve 33 opens. When the airbag 31 does not trigger the pressure sensor, the dispensing valve 33 automatically closes, so that the liquid is automatically dispensed in segments.

[0033] The soil turning component 4 consists of a frame 4121 and a soil turning claw 42. The frame 4121 is fixedly connected to the soil turning claw 42, and the side of the soil turning claw 42 is provided with a baffle that is fixedly connected to the frame 4121. During the machine's forward movement, the soil turning claw 42 passes through the saline-alkali land, turning and dividing the surface of the saline-alkali land. At the same time, the baffle prevents the mud and dirt turned out by the soil from splashing onto the machine when turning the soil on the surface of the saline-alkali land.

[0034] The roller 5 includes a hub 51 and a spiral blade 52 disposed inside the hub 51. A gear is provided on the inner side of the hub 51, and a third gear 24 is connected to the gear inside the hub 51 via a chain. When the rotating rod 22 drives the third gear 24 to rotate, the third gear 24 is connected to the gear inside the hub 51 via a chain, driving the hub 51 to rotate. At the same time, multiple sets of cones are provided on the surface of the hub 51. When the machine moves, the third gear 24 drives the hub 51 to rotate, providing assistance for the movement of the machine. At the same time, because the soil structure of saline-alkali land is poor and prone to compaction. This is because high salt content and high pH value will disrupt the aggregation between soil particles, causing soil particles to disperse, reducing porosity, and worsening water permeability and air permeability. When the hub 51 rotates, the cone pierces the soil surface and penetrates the compacted soil, making the soil structure loose, which is easier to turn over and inject chemicals. When piercing the soil, the saline soil at the bottom of the saline-alkali land is exposed, making it easier for the hub 51 to sink into the soil. After the hub 51 body is submerged in the soil, the spiral blade 52 rotates with the hub 51, further breaking up the soil to achieve a better soil breaking effect.

[0035] Working principle:

[0036] The drive motor 13 outputs power to the transmission 12, which in turn drives the first gear 14 to rotate. As the first gear 14 rotates with the transmission 12, the second gear 23 is connected to it via a chain and rotates with it. Simultaneously, the second gear 23 drives the rotating rod 22 to rotate on the frame 4121, causing the rotating rod 22 to drive the third gear 24 to rotate. The push block 25, fixed to the surface of the rotating rod 22, also rotates with it, driving the liquid outlet assembly 3 and the roller 5. The storage tank 32 contains chemical agents for remediating saline-alkali land, and the airbag 3... 1. Placed on top of the liquid storage tank 32, when the rotating rod 22 rotates, it drives the push block 25 to rotate. When the push block 25 rotates, it will intermittently squeeze the air bag 31. At the same time, the air bag 31 is equipped with a pressure sensor, and the air bag 31 is electrically connected to the liquid outlet valve 33. When the push block 25 squeezes the air bag 31 and triggers the pressure sensor, the liquid outlet valve 33 opens. When the air bag 31 does not trigger the pressure sensor, the liquid outlet valve 33 automatically closes, so that the liquid is automatically discharged in segments. During the machine's forward movement, the soil turning claw 42 passes through the saline-alkali land and turns and divides the surface of the saline-alkali land. At the same time, the baffle prevents the mud and dirt turned up from the surface of the saline-alkali land from splashing onto the machine.
