Description

Technical Field

[0001] This invention relates to the field of soil remediation technology, and in particular to a device for improving saline-alkali land soil. Background Technology

[0002] Saline-alkali land refers to land containing excessive soluble salts. The cause of soil salinization is that the soil and groundwater contain too much salt. Under strong surface evaporation, the salt remains on the surface and in the shallow soil, thus forming soil salinization.

[0003] The current method for improving saline-alkali soil commonly involves laying 20cm of gravel 40-50cm below the surface, followed by a layer of wheat straw or rice straw, and then covering it with planting soil (i.e., improved soil). This method mainly relies on excavators to dig up the saline-alkali soil, and then manually mixing the soil amendment. This is time-consuming and labor-intensive. Moreover, unimproved saline-alkali soil contains a certain amount of gravel at different layers. If the gravel is not separated, it will affect the subsequent soil improvement effect.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figures 1-8 The present invention provides a soil improvement device for saline-alkali land, including a box 1, a feeding mechanism at the top of the box 1, and a discharging mechanism at the bottom of the box 1.

[0032] A filter screen frame 2 is movably connected to the inner cavity of the housing 1. Multiple vibrators 3 are fixedly installed on the filter screen frame 2. A collection port is opened on the bottom wall of the filter screen frame 2, and multiple collection screen frames 4 are detachably connected to the collection port.

[0033] The top of the box 1 is equipped with a first motor 5. The output end of the first motor 5 is driven by a sliding frame 6. Multiple scrapers 7 are fixedly connected to the sliding frame 6. The multiple scrapers 7 correspond one-to-one with multiple collection mesh frames 4, and the scrapers 7 slide with the inner cavity of the collection mesh frame 4.

[0034] The side wall of the housing 1 is provided with a pipeline assembly 8, in which an amendment flows. Multiple nozzles 9 are connected to the pipeline assembly 8, and the nozzles 9 are located in the inner cavity of the housing 1 and below the collection mesh frame 4.

[0035] Soil is fed into the box 1 by the feeding mechanism and falls onto the filter screen 2. The filter screen 2 is driven by the vibrator 3 to screen the soil, thus effectively separating the soil from the stones. The separated stones are collected in multiple collection screens 4. At the same time, the first motor 5 drives the sliding frame 6 to slide, so that the scraper 7 moves the stones and soil in the collection screens 4. This avoids clogging caused by stones and soil and effectively removes the soil adhering to the stones. Then, the pipeline group 8 sprays the soil conditioner from the nozzle 9 to fill the separated soil with the conditioner, forming improved soil. Finally, the stones can be collected by disassembling the collection screens 4. This process realizes the separation of stones and soil in saline-alkali soil, effectively improves the soil improvement effect, and facilitates the obtaining of pure improved soil.

[0036] Further optimizing the design, the sliding frame 6 includes a horizontal plate 10, on which multiple first vertical plates 11 are fixedly connected. Each of the multiple first vertical plates 11 corresponds to and is connected to multiple scrapers 7. Multiple second vertical plates 12 are also connected to the horizontal plate 10. Each of the second vertical plates 12 is fixedly connected to a ball nut 13. The ball nut 13 is driven by a reciprocating screw 14. The reciprocating screw 14 is rotatably connected to the housing 1 and is driven by a first motor 5. The remaining second vertical plates 12 are fixedly connected to a sliding ring 15. A smooth rod 16 is slidably fitted inside the sliding ring 15 and is fixedly connected to the housing 1.

[0037] The first motor 5 drives the reciprocating screw 14 to rotate, which in turn drives the ball nut 13 to move. At the same time, the guide rod 16 and the sliding ring 15 provide guidance and support, thereby enabling the ball nut 13 to translate. This, in turn, drives the horizontal plate 10 to move through the multiple second vertical plates 12, which in turn drives the multiple first vertical plates 11 to move through the horizontal plate 10, thus enabling the multiple scrapers 7 to achieve a reciprocating scraping effect.

[0038] In a further optimized design, the output shaft of the first motor 5 is driven by a transmission rod 17. A first bevel gear 18 is fixedly connected to the transmission rod 17. The first bevel gear 18 meshes with a second bevel gear 19. The second bevel gear 19 is fixedly connected to a connecting rod 20. The connecting rod 20 is rotatably connected to the housing 1. The connecting rod 20 extends into the inner cavity of the housing 1 and is fixedly connected to a third bevel gear 21. The third bevel gear 21 meshes with a fourth bevel gear 22. The fourth bevel gear 22 is fixedly connected to a reciprocating lead screw 14. A protective cover 23 is fixedly connected to the inner wall of the housing 1, covering the third bevel gear 21 and the fourth bevel gear 22.

[0039] The first motor 5 drives the transmission rod 17 to rotate, which in turn drives the reciprocating screw 14 to rotate through the first bevel gear 18, the second bevel gear 19, the connecting rod 20, the third bevel gear 21, and the fourth bevel gear 22 in sequence. The third bevel gear 21 and the fourth bevel gear 22 are protected by the protective cover 23 to prevent them from being affected by the soil.

[0040] In a further optimized design, a flexible hose 24 is fixedly connected between the protective cover 23 and the ball nut 13, as well as between the inner wall of the housing 1 away from the protective cover 23 and the ball nut 13. The flexible hose 24 covers the reciprocating screw 14.

[0041] The telescopic hose 24 can extend and retract synchronously with the movement of the ball nut 13, thus preventing the reciprocating screw 14 from being affected by the soil.

[0042] The feeding mechanism is further optimized by including a feeding box 25, which is connected to the inner cavity of the box body 1. Multiple crushing rods 26 are rotatably connected inside the feeding box 25. One end of each crushing rod 26 is fixedly connected to a spur gear 27. Two adjacent spur gears 27 mesh with each other, and any one of the spur gears 27 is fixedly connected to the transmission rod 17.

[0043] The transmission rod 17 synchronously drives the spur gear 27 to rotate, thereby causing multiple spur gears 27 to rotate, realizing the rotation of multiple crushing rods 26, and crushing the clumped soil.

[0044] In a further optimized design, multiple support plates 28 are fixedly connected to the inner cavity of the housing 1, and multiple first spring telescopic rods 29 are fixedly connected between the support plates 28 and the filter frame 2.

[0045] While the vibrator 3 drives the filter frame 2 to vibrate, the first spring telescopic rod 29 extends and retracts in coordination, and supports the filter frame 2.

[0046] In a further optimized design, multiple mounting plates 30 are fixedly connected to the bottom of the filter frame 2. A collection frame 4 is provided between two adjacent mounting plates 30. Guide grooves 31 are respectively opened on the opposite end faces of two adjacent mounting plates 30. A pair of guide protrusions 32 are fixedly connected to the side wall of the collection frame 4. The guide protrusions 32 correspond one-to-one with the guide grooves 31 and slide in fit. The guide protrusions 32 are detachably connected to the mounting plates 30 by bolts 33. An opening and closing door 34 is provided on the side wall of the housing 1 near the bolts 33.

[0047] The mounting plate 30 can be pulled out of the collection frame 4 by opening the opening and closing door 34 and removing the bolts 33.

[0048] The scheme is further optimized by fixing a first inclined plate 35 to both ends of the collection frame 4. The first inclined plate 35 is used to abut against the scraper 7. A second spring telescopic rod 36 is fixedly connected between the scraper 7 and the first vertical plate 11.

[0049] By setting the first inclined plate 35, stones can be prevented from clogging when the scraper 7 slides. At the same time, when the collection frame 4 is pulled out, the contact between the first inclined plate 35 and the scraper 7 pushes the scraper 7 to extend and retract the second spring telescopic rod 36, thus avoiding interference with the removal of the collection frame 4.

[0050] The plan was further optimized, and pipeline group 8 was connected to pump 37.

[0051] The design is further optimized so that the discharge mechanism includes a pair of second inclined plates 38, which are symmetrically and fixedly connected to the inner side wall of the box 1. A discharge box 39 is fixedly connected between the pair of second inclined plates 38. There is a gap between the pair of second inclined plates 38, which is connected to the discharge box 39. A spiral conveying rod 41 is driven and cooperated with the discharge box 39 through a second motor 40. The end of the discharge box 39 away from the second motor 40 is open.

[0052] A pair of second inclined plates 38 facilitate the sliding of the improved soil into the discharge box 39, and the second motor 40 drives the screw conveyor 41 to rotate. While conveying the improved soil, the screw conveyor 41 can also mix the improved soil and improve the fusion effect of the improver.
