Description

Technical Field

[0001] The present invention relates to the technical field of soil treatment equipment, and particularly to a soil treatment equipment for agricultural land restoration. Background Art

[0002] Land restoration is a process of treating and restoring land that has been degraded or damaged due to production construction, pollution, overdevelopment, etc. by means of physical, chemical, biological and other technical means. With the development of industrialization and agricultural intensification, land faces problems such as heavy metal pollution, soil compaction, and declining fertility, which seriously threaten ecological security and food production. By means of soil replacement, microbial degradation, phytoremediation, etc., the content of pollutants can be effectively reduced and the soil structure can be improved; combined with measures such as the application of organic fertilizers and crop rotation and fallow, the soil fertility and biological activity can be restored. Land restoration is not only the protection of natural resources, but also an important measure to achieve ecological sustainable development, ensure national food security and the health of the human settlement environment.

[0003] In large-scale agricultural planting areas or pilot regions, the long-term repeated planting of a single crop has become a major hidden danger to soil health. On the one hand, the root distribution and growth pattern of a single crop are fixed, and coupled with frequent mechanical tillage, it is extremely easy to damage the soil aggregate structure, resulting in soil compaction, a significant decline in air permeability and water permeability, and it is difficult for crop roots to breathe and absorb nutrients normally; on the other hand, continuous planting provides a stable living environment and food source for specific pests and diseases, enabling a large number of pathogens and pests to multiply, with enhanced drug resistance, forming a vicious cycle. However, the current commonly used treatment methods such as plowing, turning the soil, and conventional fertilization can only temporarily improve the surface condition of the soil, cannot effectively restore the soil aggregate structure, and are also difficult to fundamentally inhibit the breeding of pests and diseases. The problem of soil degradation is still intensifying, seriously restricting the sustainable development of agriculture. Therefore, those skilled in the art have proposed a soil treatment equipment for agricultural land restoration to solve the above-mentioned technical problems. Summary of the Invention

[0012] Preferably, two groups of height-adjustable adjusting connection seats are arranged at equal intervals at the bottom end of the extension seat. The bottom ends of the adjusting connection seats are fixedly connected with soil covering seats. Front tips are arranged at one ends of the soil covering seats close to the collection box for inserting into the soil and guiding it. Arc-shaped swirling walls are arranged on inner walls of the soil covering seats for covering the soil guided by the front tips through swirling and piling methods.

[0013] Working principle: When repairing the soil of some large-scale agricultural planting areas or agricultural land in pilot areas, the staff first moves the device to the location of the soil to be repaired, and then connects the device to the traction device through the traction seat on the base, thereby starting the soil repair treatment; when the traction device tows the entire device to move, first as the entire device continues to move, the drive motor on the base is started, and the rotating shaft of the drive motor rotates while driving the rotating seat in the guide cover to rotate, and the rotating seat drives the shovel seat on it to rotate synchronously while rotating. The shovel plate seat shovels the compacted soil through the blade part thereof while rotating, and with the continuous rotation of the shovel plate seat and the guidance and closure of the guide cover, the compacted soil shoveled by the shovel plate seat is continuously transported into the interior of the collection box, and the compacted soil entering the collection box is transported and guided by the baffle conveyor belt at the bottom of the base to enter the processing box at the bottom of the base. When the compacted soil in the temporary storage box is transported by the baffle conveyor belt at the bottom of the base to enter the interior of the processing box, at the same time, because the overall equipment is guided and moved by the traction equipment, the overall equipment moves at the same time When the auxiliary walking wheels on the side seats rotate synchronously, the auxiliary walking wheels rotate and the mounting disc in the processing box rotates synchronously through the synchronous belt. The mounting disc rotates and drives multiple groups of arc seats on it to rotate. When the compacted soil is transported into the processing box, the compacted soil is initially crushed during the falling collision process, and the arc seats will crush it again through the cooperation between their outer walls and the inner walls of the processing box during the rotation process. At the same time, some soil blocks enter the inner layer of the inner arc seats through the gaps between the outermost arc seats and are affected by the arc seats. Under the influence of rotation, the soil lumps that enter the arc seat collide during the rotation process, so that their volume gradually decreases, and as the volume of the soil lumps decreases, they gradually enter the innermost space during the rotation of the arc seat. Finally, the soil lumps that enter the most central position are reduced to particles as the arc seat rotates and collides with the inner wall of the arc seat. The soil reduced to particles is then discharged from the gap between the arc seats as the arc seat rotates and swings. The discharged soil particles are discharged onto the soil surface through the dispersion slot at the bottom of the processing box.When the multiple arc seats in the processing box break the input soil clumps during rotation, the heating wire on the arc rod is powered on and starts. While the heating wire is powered on and starts, it generates heat and conducts it to the surface of the arc seat. During the process of the soil clumps contacting the surface of the arc seat, pests or insect eggs in the soil are killed by high temperature, thereby reducing the number of pests in the soil. Moreover, the corpses of the killed pests and the remaining harmless insect eggs can be used as organic fertilizers for the soil, thus improving the fertility of the soil during planting. When the multiple arc seats in the processing box break the input soil clumps during rotation, the vibrator on the fertilizer box starts and generates vibration. The vibration generated by the start of the vibrator is conducted to the fertilizer in the fertilizer box, so that the fertilizer in the fertilizer box is evenly dispersed into the processing box through the dispersion holes at its bottom under the influence of the vibration force, and is mixed with the soil that has been broken multiple times in the processing box and then discharged onto the surface of the planting land. And the staff can also replace the fertilizer in it by opening the cover on the fertilizer box according to the different soil conditions on site, so that the types of fertilizers can be more suitable for the soil conditions; while the whole device is moving, the separating rod on the rotating rod enters the soil during the process of moving and rotating, and uses the barbed rod on it to stir the remaining plants or weed roots in the soil. Along with the rotation of the rotating rod, the separating rod and the plants or weed roots stirred by the barbed rod on it enter the inside of the collection box through the inlet groove at the bottom of the collection box. And as the rotating rod drives the separating rod on it to keep rotating, when the separating rod continues to rotate, it limits and strips the plants or weed roots stirred out by it into the collection box through the separation groove on the collection box for centralized collection. After a certain amount of plant roots are collected in the collection box, the staff can centrally process the plant roots collected inside by opening the cleaning door on the collection box. By separating the plant roots in the soil, the degree of soil compaction and clumping can also be reduced, making the soil softer and more convenient for plants to breathe during planting. At the same time, it can also prevent the remaining plant roots in the soil from robbing the nutrients in the soil during the growth of plants, thus affecting the normal growth and development of plants in the planting land. Then the delivery pump on the base starts, and the delivery pump transports the soil conditioner in the liquid storage tank to the spray row on the extension seat through the connecting pipe, and sprays it on the surface of the soil in the planting land, so as to assist in repairing the soil that has been processed multiple times through the soil conditioner;Finally, as the overall device is continuously towed and moved, the staff adjusts the height of the adjusting connecting seat on the soil covering seat, so that the adjusted soil covering seat can penetrate into the soil. Then, when the overall device drives it to move, the front tip of the soil covering seat can be inserted deep into the soil during the movement, and during the movement, the front tip of the soil covering seat can synchronously guide and convey the shoveled soil to the position of the arc-shaped rotating wall. As the soil covering seat moves continuously and the soil at the position of the arc-shaped rotating wall increases continuously, the soil at the position of the soil covering seat will rotate and cover the soil of the planting land sprayed with the conditioner through the arc surface of the arc-shaped rotating wall on it during its movement, thus preventing the fertilizers and conditioners in the soil from evaporating due to the influence of the external environment and reducing their efficacy during use. At the same time, it can also deeply plow the soil in the farmland synchronously, thereby improving the growth effect of the plants in the subsequent planting land, and thus completing the multiple soil remediation treatment of agricultural land.

[0014] The present invention provides a soil treatment device for agricultural land remediation. It has the following beneficial effects:

[0015] 1. By shoveling and conveying the compacted soil layer on the surface of the planting land and dispersing and crushing the soil lumps in the soil by means of multiple crushing means, this treatment method can, on the one hand, improve the air permeability and water absorption of the treated soil, thus creating an ideal growth environment for crop roots. On the other hand, by shoveling the compacted soil, it can effectively destroy the hidden pest nests and pathogen carriers in the soil, reduce the breeding of pests and diseases, and at the same time promote the improvement of soil microbial activity, fundamentally improving the soil ecology and providing a long-term guarantee for sustainable agricultural production.

[0016] 2. When treating the compacted soil lumps, the multiple crushing treatment technology can effectively break the soil compacted structure, significantly improve the soil looseness, improve the air permeability and water permeability of the soil, create an excellent environment for the growth of plant roots. At the same time, with the assistance of high-temperature treatment, it can efficiently kill pests and insect eggs in the soil, curb the breeding of pests and diseases from the source, reduce the use of pesticides, ensure green ecological planting, and the pests and insect eggs killed by high temperature can be converted into high-quality soil fertilizers after treatment, realizing the recycling of resources, supplementing the soil with rich organic matter and nutrients. In addition, through the vibration dispersion technology, the fertilizers are evenly distributed in the crushed soil, enabling the nutrients to fully penetrate, improving the soil fertility, promoting the healthy growth of plants, taking into account environmental protection and high efficiency, and having important application value.

[0017] 3. During the soil treatment process of the present invention, by precisely disturbing, separating, and collecting the residual roots of planted crops or weeds, the degree of soil compaction can be effectively reduced, and the looseness and air permeability of the soil can be significantly improved. This treatment method makes the soil softer during the planting process, creating a good breathing environment for plant roots, promoting the healthy growth and extension of roots. At the same time, eliminating the residual plant roots can avoid their competition with the target planted crops for nutrients during the plant growth process, ensuring that the planted crops obtain sufficient nutrient supply from the source and facilitating their normal growth and development. In addition, by spraying and using soil conditioners, the soil structure can be further repaired, soil trace elements can be supplemented, the physical and chemical properties of the soil can be improved, and the soil fertility can be enhanced, creating a high-quality soil ecological environment for crop growth and realizing the efficient and sustainable development of agricultural planting.

[0018] 4. The present invention adopts a soil covering treatment method after soil treatment, which has many significant advantages. First, after completing multiple soil repair treatments in the front part, through the soil covering operation, the soil conditioners mixed in the soil and sprayed on the soil surface can be effectively protected, significantly reducing the volatilization and loss of fertilizers and conditioners caused by external environmental factors such as light, wind, and high temperature, and maintaining their activity and efficacy to the greatest extent, ensuring that the conditioner can continuously and stably play the role of improving soil structure and enhancing soil fertility. Second, the soil covering process realizes the deep plowing of the soil in the planting area, breaks the soil compaction layer, increases soil porosity, improves soil aeration and water permeability, creates better conditions for plant root growth, and then effectively increases the rooting depth and nutrient absorption efficiency of the planted crops, comprehensively promoting the healthy growth of the planted crops in the subsequent planting area and significantly improving crop yield and quality.

Specific embodiments

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to the attached Figure 1 - attached Figure 3 , an embodiment of the present invention provides a soil treatment device for agricultural land restoration, including a base 1, a towing seat 3 is fixedly connected to the middle of one side of the base 1, a fixed pin is inserted into the middle of the towing seat 3, a guiding cover 2 is fixedly connected to one side of the middle of the base 1 close to the towing seat 3, a rotating seat 24 is rotatably connected to the middle of the inner side of the guiding cover 2, a plurality of shovel plate seats 4 are circumferentially arranged on the outer wall of the rotating seat 24, and a cutting edge is provided on the side of each shovel plate seat 4 away from the rotating seat 24. A drive motor 20 is arranged on one side of the middle of the rear end of the base 1, and the output end of the drive motor 20 penetrates through the guiding cover 2 and is connected to the middle of one end of the rotating seat 24. A temporary storage box 5 is arranged on one side of the bottom end of the base 1, and one side of the temporary storage box 5 is communicated with the corresponding position inside the guiding cover 2. A baffle conveyor belt 6 is arranged on one side of the middle of the bottom end of the base 1.

[0032] When the traction equipment pulls the overall equipment to move, first, as the overall equipment keeps moving, the drive motor 20 on the base 1 starts. While the rotating shaft of the drive motor 20 rotates, it drives the rotating seat 24 in the guiding cover 2 to rotate. While the rotating seat 24 rotates, it drives the shovel plate seat 4 on it to rotate synchronously. While the shovel plate seat 4 rotates, it shovels the compacted soil through the cutting edge on it. And with the continuous rotation of the shovel plate seat 4 and the guiding and closing of the guiding cover 2, the compacted soil shoveled by the shovel plate seat 4 is continuously transported into the interior of the collection box 8. The compacted soil that enters the collection box 8 is then transported and guided by the baffle conveyor belt 6 at the bottom of the base 1 to enter the processing box 7 at the bottom of the base 1.

[0033] Please refer to the attached Figure 4 - attached Figure 5 , the middle part of the bottom end of the base 1 is fixedly connected with a processing box 7. The baffle conveyor belt 6 is used to transport the soil in the temporary storage box 5 into the processing box 7. The middle parts of the front and rear sides of the processing box 7 are fixedly connected with side seats 18, and the tops of the side seats 18 are respectively connected to the corresponding positions of the base 1. The middle parts of the bottom ends of the side seats 18 are rotatably connected with auxiliary walking wheels 21. The middle and lower parts of both sides of the inner wall of the processing box 7 are rotatably connected with mounting disks 26, and both ends of the mounting disks 26 sequentially penetrate through the processing box 7 and the side seats 18 and extend outwards. The extended ends of the mounting disks 26 on the same side are connected to the rotating shafts of the auxiliary walking wheels 21 through a synchronous belt 19.

[0034] When the compacted soil in the temporary storage box 5 enters the interior of the processing box 7 through the transportation of the baffle conveyor belt 6 at the bottom of the base 1, at the same time, since the overall equipment is guided and moved by the traction equipment, when the overall equipment moves, it will also drive the auxiliary walking wheels 21 on the side seats 18 to rotate synchronously. While the auxiliary walking wheels 21 rotate, they synchronously drive the mounting disks 26 in the processing box 7 to rotate through the synchronous belt 19. While the mounting disks 26 rotate, they drive multiple arc-shaped seats 25 on them to rotate.

[0035] When the compacted soil is conveyed into the processing box 7, the soil lumps are initially broken during the falling and colliding process. During the rotation of the arc-shaped seat 25, the cooperation between its outer wall and the inner wall of the processing box 7 will also break it again. At the same time, a part of the soil lumps enters the interior of the inner arc-shaped seat 25 through the gaps between the outermost arc-shaped seats 25. Affected by the rotation of the arc-shaped seat 25, the soil lumps that enter the arc-shaped seat 25 collide during its rotation, causing their volume to gradually shrink. As the volume of the soil lumps shrinks, they gradually enter the innermost space during the rotation of the arc-shaped seat 25. Finally, the soil lumps at the center position shrink into a granular state with the rotation of the arc-shaped seat 25 and its collision with the inner wall of the arc-shaped seat 25. After that, the soil that has shrunk into a granular state is thrown out through the gaps between the arc-shaped seats 25 as the arc-shaped seat 25 rotates. The discharged soil particles are discharged onto the soil surface through the dispersion grooves 27 at the bottom of the processing box 7.

[0036] Please refer to the attached Figure 6 , there are multiple groups of arc-shaped seats 25 arranged in a circumferential array between the mounting plates 26, and the distance between adjacent groups of arc-shaped seats 25 gradually decreases from the outside to the inside. A plurality of arc-shaped rods 29 are evenly arranged in the middle of the inner side of the arc-shaped seat 25, and heating wires 28 are arranged on the arc-shaped rods 29. A plurality of dispersion grooves 27 are equidistantly opened at the bottom of the processing box 7.

[0037] When the multiple arc-shaped seats 25 in the processing box 7 break the input soil lumps during rotation, the heating wires 28 on the arc-shaped rods 29 are powered on and started. While the heating wires 28 are powered on and started, they generate heat and conduct it to the surface of the arc-shaped seat 25. During the process of the soil lumps contacting the surface of the arc-shaped seat 25, pests or insect eggs in the soil are killed by high temperature, thereby reducing the number of pests in the soil. And the corpses of the killed pests and the remaining harmless insect eggs can also be used as organic fertilizers for the soil, thereby improving the fertility of the soil during the planting process.

[0038] Please refer to the attached Figure 7 , a fertilizer box 15 is provided in the middle of the top end of the base 1. A vibrator 16 is provided in the middle of one side of the fertilizer box 15. The top of the fertilizer box 15 is rotatably connected with a closed cover 31. A plurality of groups of dispersion holes 30 are equidistantly opened at the inner bottom of the fertilizer box 15, and the dispersion holes 30 connect the inside of the fertilizer box 15 with the inside of the processing box 7.

[0039] While the multiple arc-shaped seats 25 in the processing box 7 crush the incoming soil clumps during rotation, the vibrator 16 on the fertilizer box 15 starts and generates vibrations. The vibrations generated by the start of the vibrator 16 are conducted to the fertilizer in the fertilizer box 15, so that the fertilizer in the fertilizer box 15 is evenly dispersed into the processing box 7 through the dispersion holes 30 at its bottom under the influence of the vibration force, and is mixed with the soil that has been crushed multiple times in the processing box 7 and then discharged onto the surface of the planting land. And the staff can also replace the fertilizer in it by opening the closing cover 31 on the fertilizer box 15 according to the different soil conditions on site, so that the type of fertilizer can be more suitable for the soil conditions.

[0040] Please refer to the appendix Figure 8 , on one side of the middle of the base 1 away from the towing seat 3, a collection box 8 is fixedly connected. An inlet groove 32 is opened on one side of the bottom of the collection box 8. A plurality of separation grooves 22 are equidistantly opened on the side of the collection box 8 away from the inlet groove 32. A rotating rod 33 is rotatably connected to the side of the bottom of the collection box 8 away from the inlet groove 32. A plurality of groups of separation rods 23 are circumferentially arranged on the rotating rod 33. On the outer wall of one side of the separation rod 23 away from the rotating rod 33, a plurality of groups of barbed rods 34 are fixedly connected at equal intervals. A cleaning door 13 is arranged in the middle of one side of the collection box 8.

[0041] While the whole device is moving, the separation rods 23 on the rotating rod 33 enter the soil during the process of moving and rotating, and the residual plants or weed roots in the soil are stirred by the barbed rods 34 on them. Along with the rotation of the rotating rod 33, the separation rods 23 and the plants or weed roots stirred by the barbed rods 34 on them enter the interior of the collection box 8 through the inlet groove 32 at the bottom of the collection box 8. And as the rotating rod 33 drives the separation rods 23 on it to rotate continuously, when the separation rods 23 continue to rotate, they limit and strip the plants or weed roots stirred out by them through the separation grooves 22 on the collection box 8 into the interior of the collection box 8 for centralized collection.

[0042] After a certain amount of plant roots are collected in the collection box 8, the staff can centrally process the plant roots collected inside by opening the cleaning door 13 on the collection box 8. By separating the plant roots in the soil, the degree of soil compaction and clumping can also be reduced, making the soil softer and more convenient for plants to breathe during the planting process. At the same time, it can also prevent the residual plant roots in the soil from robbing the nutrients in the soil during the growth process of the plants, thus affecting the normal growth and development of the plants in the planting land.

[0043] Please refer to the appendix Figure 9, a middle part on one side of the bottom end of the base 1 far from the towing seat 3 is fixedly connected with an extension seat 12. A spray row 11 is arranged at the middle and lower part on one side of the extension seat 12 close to the collection box 8. A liquid storage tank 14 is arranged at one side of the middle part of the top end of the base 1. A liquid injection pipe is arranged at the middle part of the top end of the liquid storage tank 14. The top end of the liquid injection pipe is threadedly connected with a sealing cover. A delivery pump 17 is arranged at the middle part on one side of the top end of the base 1 far from the towing seat 3. The liquid inlet of the delivery pump 17 is communicated with the inner bottom of the liquid storage tank 14 through a connecting pipe, and the liquid outlet of the delivery pump 17 is communicated with the liquid inlet of the spray row 11 through a connecting pipe.

[0044] After that, the delivery pump 17 on the base 1 is started. The delivery pump 17 transports the soil conditioner in the liquid storage tank 14 to the spray row 11 on the extension seat 12 through the connecting pipe, and sprays it on the surface of the soil in the planting area through the spray row 11, so as to assist in repairing the soil after multiple treatments again through the soil conditioner.

[0045] Please refer to the appendix Figure 10 , two groups of height-adjustable adjusting connection seats 10 are equidistantly arranged at the bottom end of the extension seat 12. The bottom ends of the adjusting connection seats 10 are fixedly connected with soil covering seats 9. Front pointed parts 35 are arranged at one ends of the soil covering seats 9 close to the collection box 8 for inserting into the soil and guiding it. Arc-shaped swirling walls 36 are arranged on the inner walls of the soil covering seats 9 for covering the soil guided by the front pointed parts 35 through swirling and piling methods.

[0046] Finally, as the whole device is continuously towed and moved, the staff adjusts the height of the adjusting connection seats 10 on the soil covering seats 9, so that the adjusted soil covering seats 9 can penetrate into the soil. Then, when the whole device drives it to move, the front pointed parts 35 on the soil covering seats 9 can be inserted deep into the soil during the movement, and during the movement, the front pointed parts 35 on the soil covering seats 9 synchronously guide and transport the shoveled soil to the position of the arc-shaped swirling wall 36.

[0047] As the soil covering seats 9 keep moving and the soil at the position of the arc-shaped swirling wall 36 continuously increases, the soil at the position of the soil covering seats 9 will cover the soil in the planting area sprayed with the conditioner through the arc-shaped surface of the arc-shaped swirling wall 36 on it during its movement, so as to prevent the fertilizer and conditioner in the soil from evaporating under the influence of the external environment and reducing their efficacy during use. At the same time, the soil in the farming land can be plowed deeply synchronously, so as to improve the growth effect of the plants in the subsequent planting area.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
