For soils with low salinity, improvement can be achieved in a single treatment.

Description

Technical Field

[0001] This invention relates to the field of saline-alkali land management technology, specifically to an apparatus and method for treating soil salinization. Background Technology

[0002] Saline-alkali land is a general term for both saline and alkali land. Saline land mainly refers to saline soils with high chloride or sulfate content, which are alkaline but not necessarily with a high pH value. Alkaline land refers to soils containing carbonates or biphosphates, which have a higher pH value and are alkaline. Saline-alkali soils have low organic matter content, low soil fertility, and poor physical and chemical properties, which are not conducive to plant growth. The improvement of saline-alkali land is a global challenge. No matter what methods are mentioned above, they cannot truly solve the problem of saline-alkali land. The task of improving saline-alkali land is urgent. Existing methods for improving saline-alkali land mainly involve planting salt- and alkali-tolerant plants or spraying soil conditioners. However, due to the large area of ​​saline-alkali land, auxiliary equipment is required.

[0003] For example, application number CN202310344072.7 discloses a pre-embedded soil treatment insertion device, including:

[0004] Device frame;

[0005] A moving mechanism is mounted on a device frame. The moving mechanism includes a driving component and a moving plate. The driving component is mounted on the device frame, and the moving plate is mounted on the driving component.

[0006] A punching mechanism is mounted on a movable plate. The punching mechanism includes a punching component, two support rods, and a scraping plate. The punching component is mounted on the movable plate. The two support rods are fixedly mounted on the bottom of the outer wall of the movable plate. The scraping plate is fixedly mounted between the two support rods.

[0007] A pipe-threading mechanism, mounted on a movable plate, includes an installation component, multiple steel pipes, multiple sets of telescopic components, multiple sets of fixing components, and multiple fixing rods. The installation component is mounted on the movable plate. Each steel pipe is equidistantly positioned on the installation component. Each set of telescopic components is located inside a steel pipe. Each set of fixing components is mounted on a telescopic component. Each fixing rod is mounted on a fixing component.

[0008] The invention includes multiple biodegradable tubing units, each slidably embedded in the inner wall of a steel pipe. Each tubing has four fixing holes on its outer wall, and each fixing rod is slidably embedded in the inner wall of these holes. This invention uses a driving component to move a moving plate, which in turn moves the drilling and insertion mechanisms synchronously. This allows the insertion mechanism to move onto the original drilling mechanism, preventing the entire insertion device from moving and ensuring the steel pipe is accurately inserted into the drilled holes, thus improving insertion accuracy. A scraping plate on the support rod removes dirt from the outer wall of the steel needle, preventing it from affecting subsequent drilling operations.

[0009] However, the aforementioned pre-buried soil treatment tube device cannot continuously treat the soil, and the beneficial bacteria have no adaptation period. During the treatment process, the beneficial bacteria come into direct contact with the soil, which seriously affects the number of beneficial bacteria in the early stage, resulting in slow soil treatment efficiency. Furthermore, insufficient energy in the later stage can cause the beneficial bacteria to die unexpectedly during proliferation, which seriously reduces the effective time of the beneficial bacteria and thus leads to poor treatment results.

[0012] The drilling and pipe-laying assembly includes a positioning plate. The upper surface of the positioning plate has a treatment hole and a pipe-laying hole. A feeding groove is provided on one side of the positioning plate, which communicates with the pipe-laying hole. A drilling bit is slidably connected inside the treatment hole, and a treatment pipe is slidably connected inside the pipe-laying hole. An elastic sleeve is fixedly connected to the lower part of the inner cavity of the pipe-laying hole. A sealing groove is provided at the bottom of the positioning plate, and a drive motor is installed at the top of the sealing groove. A gear is fixedly connected to the output end of the drive motor. The side of the positioning plate opposite to the feeding groove is fixedly connected to the output end of the hydraulic assembly two.

[0013] The treatment tube includes a treatment tube body, an air exchange groove on the outside of the treatment tube body, an air tube fixedly connected to the top of the inner cavity of the treatment tube body, and a culture medium slidably connected inside the treatment tube body.

[0014] In a preferred embodiment, the inner cavity of the treatment tube is filled with liquid biological matrix and beneficial soil bacteria, the end of the trachea facing away from the top of the inner cavity of the treatment tube is inserted into the liquid biological matrix, and the culture medium is wrapped with a biodegradable film.

[0015] In a preferred embodiment, the drilling bit includes a drill bit body, a plurality of slotted teeth are fixedly connected to the outside of the drill bit body, and a connecting groove is provided at one end of the drill bit body.

[0016] As a preferred embodiment, several sets of slotted teeth form several sets of spaced meshing tooth rings along the outer axial direction of the drill bit body, and the outer surface of the slotted teeth is rough.

[0017] In a preferred embodiment, an extrusion plate is fixedly connected to one output end of the hydraulic component. The size of the extrusion plate is adapted to the connecting groove, and the outer diameter of the extrusion plate is equal to the inner diameter of the discharge hole.

[0018] In a preferred embodiment, the gear meshes with the meshing gear ring, the limiting plate extends into the closed groove, and the edge of the limiting plate is tangent to the bottom of the treatment hole.

[0019] In a preferred embodiment, the outer diameter of the treatment tube is larger than the outer diameter of the drill bit body and smaller than the outer diameter of the meshing gear ring.

[0020] In a preferred embodiment, the upper tube assembly includes a transition frame, a feeding trough is provided on one side of the transition frame, and guide plates are fixedly connected to the inner walls of both sides of the feeding trough.

[0021] In a preferred embodiment, the three output ends of the hydraulic component are fixedly connected to a push plate, the push plate is positioned corresponding to the feeding trough, and the bottom of the feeding trough is provided with an inclined groove on the side adjacent to the drilling and pipe-laying component.

[0022] As a preferred embodiment, a method of using an apparatus for soil salinization control includes: planning placement points for treatment pipes in the salinized soil; placing several sets of treatment pipes into the feeding trough; the treatment pipes resting on a guide plate via an external ventilation trough; and using a hydraulic component three to drive a pusher plate to push one set of treatment pipes into the pipe placement hole. The friction of the elastic sleeve fixes the position of the treatment pipes. A hydraulic component one pushes a drilling bit through a pressing disc to drill a deep hole in the soil. A drive motor is activated to drive the gears, causing the drilling bit to rotate one revolution. Then, the hydraulic component one lifts the drill bit to its initial position. A hydraulic component two moves the drilling and placement assembly away from the upper pipe assembly until the placement hole coincides with the center of the original treatment hole. At this point, the pressing disc moves vertically... Aligning with the placement hole, the treatment tube is pressed into the deep pit by a hydraulically driven extrusion disc. The moving device inserts treatment tubes at all placement points. After the beneficial bacteria inside the treatment tube have been self-replicating for a period of time, air is continuously blown into the treatment tube through the air tube. The air pressure pushes the culture medium upward. Then, the air and water in the soil mix with the liquid biological matrix and beneficial bacteria in the inner cavity of the treatment tube. The beneficial bacteria are screened by the air and water in the soil. After the membrane layer on the outside of the culture medium degrades and breaks, the culture medium mixes with the screened beneficial bacteria to provide nutrients for the screened beneficial bacteria, helping them to replicate on a large scale for the second time. At the same time, the water in the soil fills the inside of the treatment tube, causing the beneficial bacteria to overflow into the soil along with the water, thus repairing the soil.

[0023] (II) Beneficial Effects

[0024] This invention provides an apparatus and method for treating soil salinization, which has the following beneficial effects:

[0025] 1. This invention, through the setting of a perforation and tube placement assembly, allows beneficial bacteria to be cultivated using a biological substrate after the treatment tube enters the treatment hole. While the drill bit is inside the treatment hole, the gears maintain constant engagement with the meshing gear ring formed by the slotted teeth. When the drive motor rotates the gears, it causes the drill bit to rotate after drilling. Simultaneously, the rough surface of the slotted teeth loosens the soil on the inner wall of the treatment hole, creating protrusions that facilitate the entry of soil from the inner wall of the treatment hole into the treatment tube through the ventilation groove. Furthermore, air is pumped into the treatment tube through the air pipe, causing the culture medium to be pressurized and... The rising process allows some soil, water, and air from the inner wall of the treatment pore to enter the treatment pipe and mix with beneficial bacteria, completing the screening of beneficial bacteria. At the same time, it gives beneficial bacteria an adaptation period and a subsequent reproduction period, resulting in the proliferation of a large number of adapted beneficial bacteria, so as to better improve the saline-alkali land in the future. After the biodegradable film on the outside of the culture medium degrades and breaks, it can provide energy for beneficial bacteria a second time, so as to increase the effective time of beneficial bacteria and carry out secondary proliferation, thereby increasing the number and duration of action of beneficial bacteria. For soils with low salinity, soil improvement can be completed in one treatment.

[0026] 2. This invention comprises a driving component, a drilling and pipe-laying component, and a pipe-loading component. When the treatment pipe is inside the feeding trough, it is hung on the upper part of the guide plate through an external ventilation trough. The hydraulic component three pushes the treatment pipe inside the feeding trough with a push plate, moving it to the inclined trough position. Under gravity, the treatment pipe automatically slides down and then enters the elastic sleeve through the feeding trough, completing automatic feeding. The device can carry several treatment pipes at once, avoiding back-and-forth material handling and improving treatment efficiency. The hydraulic component one squeezes and lifts the drilling drill bit through the extrusion plate, thereby drilling treatment holes in saline-alkali land. When the hydraulic component two drives the drilling and pipe-laying component to move, the drilling drill bit is blocked by the limiting plate, and the extrusion plate moves out of the connecting groove and to directly above the treatment pipe. The hydraulic component one squeezes the treatment pipe into the treatment hole through the extrusion plate, facilitating precise installation and positioning of the treatment pipe.

In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0042] Example 1

[0043] like Figure 1-7 As shown, this embodiment provides a device for soil salinization control, including a traveling drive assembly 1. The traveling drive assembly 1 is provided with a drilling and pipe laying assembly 2 and a pipe mounting assembly 3. The traveling drive assembly 1 includes a traveling frame 11. A hydraulic assembly 12 is provided on the top of the traveling frame 11. A hydraulic assembly 13 and a hydraulic assembly 15 are respectively installed on both sides of the traveling frame 11. A limit plate 14 is fixedly connected to the bottom of the inner cavity of the traveling frame 11.

[0044] The drilling and pipe-laying assembly 2 includes a positioning plate 23. The upper surface of the positioning plate 23 is provided with a treatment hole 24 and a pipe-laying hole 25. A feeding groove is provided on one side of the positioning plate 23, which is connected to the pipe-laying hole 25. A drilling drill bit 22 is slidably connected inside the treatment hole 24. A treatment pipe 21 is slidably connected inside the pipe-laying hole 25. An elastic sleeve 26 is fixedly connected to the lower part of the inner cavity of the pipe-laying hole 25. A sealing groove 27 is provided at the bottom of the positioning plate 23. A drive motor 29 is installed at the top of the sealing groove 27. A gear 28 is fixedly connected to the output end of the drive motor 29. The side of the positioning plate 23 away from the feeding groove is fixedly connected to the output end of the hydraulic assembly 2 13.

[0045] The treatment tube 21 includes a treatment tube body 214, an air exchange groove 212 is provided on the outside of the treatment tube body 214, an air tube 211 is fixedly connected to the top of the inner cavity of the treatment tube body 214, and a culture medium 213 is slidably connected inside the treatment tube body 214.

[0046] Specifically, the hydraulic component 12 drives the drilling bit 22 to drill a treatment hole in the saline-alkali land. Then, the hydraulic component 23 moves the position of the drilling and pipe laying component 2, so that the treatment pipe 21 moves to the original position of the drilling bit 22. Then, the hydraulic component 12 drives the treatment pipe 21 into the treatment hole drilled by the drilling bit 22. The limiting plate 14 slides inside the closed groove 27, so that the treatment pipe 21 can be accurately moved above the treatment hole.

[0047] Furthermore, the inner cavity of the treatment tube body 214 is filled with liquid biological matrix and beneficial soil bacteria, and the end of the trachea 211 opposite to the top of the inner cavity of the treatment tube body 214 is inserted into the liquid biological matrix. The culture medium 213 is wrapped with a biodegradable film.

[0048] Specifically, after the treatment tube 21 enters the treatment hole, beneficial bacteria can be cultivated using a biological substrate. When air is pumped into the treatment tube 21 through the air tube 211, the culture medium 213 rises under pressure, allowing some soil, water, and air from the inner wall of the treatment hole to enter the treatment tube 21 and mix with the beneficial bacteria. This process screens the beneficial bacteria and provides them with an adaptation period and a subsequent reproduction cycle, resulting in a large-scale proliferation of adapted beneficial bacteria for better subsequent improvement of saline-alkali land. Furthermore, after the biodegradable film on the outside of the culture medium 213 degrades and breaks, it can provide a secondary energy source for the beneficial bacteria, extending their effective time and allowing for secondary proliferation. This increases the number and duration of action of beneficial bacteria, enabling soil improvement in low-salinity soils to be achieved in a single treatment.

[0049] It should be noted that the beneficial bacteria are a mixture of various alkaliphilic and halophilic microorganisms, and the biological substrate is a substrate used for culturing alkaliphilic and halophilic microorganisms. Among them, culture medium 213 is a solid substrate and is sealed and wrapped with a biodegradable film.

[0050] Furthermore, the culture medium 213 has a hole in the center for the air exchange groove 212 to pass through, and the air exchange groove 212 is detachably connected to the treatment tube body 214.

[0051] like Figure 8 As shown, the drilling bit 22 includes a drill bit body 221, and several sets of slotted teeth 222 are fixedly connected to the outside of the drill bit body 221. A connecting groove 223 is opened at one end of the drill bit body 221.

[0052] Furthermore, several sets of slotted teeth 222 form several sets of intermittent meshing tooth rings along the outer axial direction of the drill bit body 221, and the outer surface of the slotted teeth 222 is rough.

[0053] Furthermore, the output end of the hydraulic component 12 is fixedly connected to an extrusion plate, the size of which is adapted to the connecting groove 223, and the outer diameter of the extrusion plate is equal to the inner diameter of the discharge hole 25.

[0054] Specifically, hydraulic component 12 squeezes and lifts the drilling bit 22 through the extrusion plate, thereby creating a treatment hole in the saline-alkali land. When hydraulic component 23 drives the drilling and pipe laying component 2 to move, the drilling bit 22 is blocked by the limiting plate 14, and the extrusion plate moves out of the connecting groove 223 and moves directly above the treatment pipe 21. Hydraulic component 12 squeezes the treatment pipe 21 into the treatment hole through the extrusion plate, which facilitates the precise installation and positioning of the treatment pipe 21.

[0055] Furthermore, the gear 28 meshes with the meshing gear ring, the limiting plate 14 extends into the closed groove 27, and the edge of the limiting plate 14 is tangent to the bottom of the treatment hole 24.

[0056] Specifically, when the drilling bit 22 is inside the treatment hole 24, the gear 28 always maintains engagement with the meshing gear ring formed by the slotted teeth 222. When the drive motor 29 drives the gear 28 to rotate, it will drive the drilling bit 22 to rotate after drilling is completed. At the same time, the surface of the slotted teeth 222 is rough, which makes the soil on the inner wall of the treatment hole loose and forms a protrusion on the inner wall, so that after the treatment pipe 21 is inside the treatment hole, the soil on the inner wall of the treatment hole can enter the treatment pipe 21 through the ventilation groove 212.

[0057] Furthermore, the outer diameter of the treatment tube 21 is larger than the outer diameter of the drill bit body 221 but smaller than the outer diameter of the meshing gear ring.

[0058] Specifically, after the treatment tube 21 enters the treatment hole, it will squeeze the protrusion formed by the slotted teeth 222. The protrusion will position the treatment tube 21 and keep the treatment tube 21 vertical.

[0059] like Figure 9 As shown, the upper tube assembly 3 includes a transition frame 31, a feeding trough 32 is provided on one side of the transition frame 31, and guide plates 33 are fixedly connected to the inner walls of both sides of the feeding trough 32.

[0060] Furthermore, a push plate is fixedly connected to the output end of the hydraulic component 315. The push plate corresponds to the position of the feeding trough 32. An inclined groove is provided on the bottom of the feeding trough 32 on the side adjacent to the drilling and pipe-laying component 2.

[0061] Specifically, when the treatment pipe 21 is inside the feeding trough 32, the treatment pipe 21 is hung on the upper part of the guide plate 33 through the external ventilation trough 212. The hydraulic component 3 15 pushes the treatment pipe 21 inside the feeding trough 32 through the push plate, so that the treatment pipe 21 moves to the inclined trough position. Under the action of gravity, the treatment pipe 21 will automatically slide down and then enter the elastic sleeve 26 through the feed trough to complete the automatic feeding. Moreover, the device can carry several treatment pipes 21 at one time, which improves the efficiency of treatment by avoiding back and forth material picking.

[0062] This invention also provides a method of using an apparatus for soil salinization control. The apparatus includes planning placement points for treatment pipes 21 in the salinized soil, placing several sets of treatment pipes 21 inside a feeding trough 32. At this time, the treatment pipes 21 rest on a guide plate 33 through an external ventilation trough 212. A set of treatment pipes 21 is pushed into a pipe-laying hole 25 by a push plate driven by a hydraulic component 3 15. The position of the treatment pipes 21 is fixed by the friction of an elastic sleeve 26. A hydraulic component 1 12 pushes a drilling bit 22 through a pressing disc to drill a deep hole in the soil. A drive motor 29 drives a gear 28 to rotate the drilling bit 22 one revolution. Then, the hydraulic component 1 12 lifts the bit to its initial position. A hydraulic component 2 13 moves the drilling and pipe-laying assembly 2 away from the upper pipe assembly 3 until the pipe-laying hole 25 coincides with the center of the original treatment hole 24. At this point, the pressing disc... Aligning vertically with the placement hole 25, the hydraulic component 12 drives the extrusion disc to press the treatment tube 21 into the deep pit. The moving device inserts the treatment tube 21 at all placement points. After the beneficial bacteria inside the treatment tube 21 have replicated for a period of time, air is continuously blown into the treatment tube 21 through the air pipe 211. The air pressure will push the culture medium 213 upward. Then, the air and water in the soil will mix with the liquid biological matrix and beneficial bacteria in the inner cavity of the treatment tube body 214. The beneficial bacteria are screened by the air and water in the soil. After the membrane layer on the outside of the culture medium 213 degrades and breaks, the culture medium 213 will mix with the screened beneficial bacteria to provide nutrients for the screened beneficial bacteria, helping the screened beneficial bacteria to replicate on a large scale for the second time. At the same time, the water in the soil will fill the inside of the treatment tube 21, so that the beneficial bacteria overflow into the soil along with the water, thus repairing the soil.

[0063] In this process, air can be blown into the treatment pipe 21 by setting a main pipe with several branch pipes and several connecting pipes on the branch pipes. The connecting pipes are connected to the air pipe 211, and then air is blown into the main pipe by a fan, thus completing the simultaneous blowing of air into several treatment pipes 21.

[0064] Example 2

[0065] Compared with Embodiment 1, the device for soil salinization control in this embodiment does not have an upper pipe assembly 3 and a hydraulic assembly 15 on the driving component 1, and the drilling and pipe laying assembly 2 does not have an external feeding trough. In this embodiment, the treatment pipe 21 is directly inserted into the elastic sleeve 26 during operation. The elastic sleeve 26 fixes the position of the treatment pipe 21 through friction. The hydraulic assembly 12 pushes the drilling drill bit 22 through the extrusion disc to drill a deep hole in the soil, and the drive motor 29 is activated to drive the gear 28. The drilling bit 22 is rotated one revolution, and then lifted to the initial position by hydraulic component 12. Hydraulic component 213 drives the drilling and tube placement component 2 to move away from the upper tube component 3 until the tube placement hole 25 coincides with the center of the original treatment hole 24. Hydraulic component 12 drives the extrusion plate to press the treatment tube 21 into the deep pit. The moving device drives the treatment tube 21 into all placement points. Then the drilling and tube placement component 2 is reset so that the extrusion plate moves back into the connecting groove 223. The operation of adding treatment tube 21 is repeated.

[0066] It should be noted that a collection box can be installed inside the driving component 1 on the side opposite to the drilling and pipe laying component 2 to carry several treatment pipes 21.

2. The device for treating soil salinization according to claim 1, characterized in that: The outer diameter of the treatment tube (21) is greater than the outer diameter of the drill bit body (221) and less than the outer diameter of the meshing gear ring.

3. The device for treating soil salinization according to claim 1, characterized in that: The upper tube assembly (3) includes a transition frame (31), and a feeding trough (32) is provided on one side of the transition frame (31). Guide plates (33) are fixedly connected to the inner walls on both sides of the feeding trough (32).

4. The device for treating soil salinization according to claim 3, characterized in that: The output end of the hydraulic component three (15) is fixedly connected to a push plate, the push plate is positioned corresponding to the feeding trough (32), and the bottom of the feeding trough (32) is provided with an inclined groove on the side adjacent to the drilling and pipe laying component (2).

5. A method of using a device for soil salinization control, employing the device described in any one of claims 1-4, characterized in that: The process includes planning the placement points of the treatment pipes (21) in the saline-alkali land, placing several sets of treatment pipes (21) into the loading trough (32), at which point the treatment pipes (21) are placed on the guide plate (33) through the external ventilation trough (212), and the push plate driven by the hydraulic component three (15) pushes a set of treatment pipes (21) into the pipe placement hole (25), and the position of the treatment pipes (21) is fixed by the friction of the elastic sleeve (26), the hydraulic component one (12) pushes the drilling drill bit (22) to drill a deep hole in the soil through the extrusion plate, the drive motor (29) is started to drive the gear (28) to drive the drilling drill bit (22) to rotate one revolution, and then the hydraulic component one (12) lifts it to the initial position, and the drilling and pipe placement component (2) is moved away from the upper pipe component (3) by the hydraulic component two (13) until the center of the pipe placement hole (25) coincides with the center of the original treatment hole (24), at which point the extrusion plate moves vertically and the pipe placement component (2) is placed in the same direction as the pipe placement hole (25). The tube holes (25) are aligned, and the extrusion plate is driven by the hydraulic component (12) to press the treatment tube (21) into the deep pit. The moving device pushes the treatment tube (21) into all the placement points. After the beneficial bacteria inside the treatment tube (21) have been self-replicating for a period of time, air is continuously blown into the treatment tube (21) through the air tube (211). The air pressure will push the culture medium (213) upward. Then the air and water in the soil will mix with the liquid biological matrix and soil beneficial bacteria in the inner cavity of the treatment tube body (214). The beneficial bacteria are screened by the air and water in the soil. After the membrane layer outside the culture medium (213) degrades and breaks, the culture medium (213) will mix with the screened beneficial bacteria to provide nutrients for the screened beneficial bacteria and help the screened beneficial bacteria to replicate on a large scale for the second time. At the same time, the water in the soil will fill the inside of the treatment tube (21), so that the beneficial bacteria overflow into the soil with the water and repair the soil.
