Description

Technical Field

[0001] This invention relates to the field of soil improvement technology, specifically to a method and apparatus for improving albic soil. Background Technology

[0002] Albic soil is a type of obstacle soil. The low yield of albic soil is mainly caused by two factors: first, the black soil layer is thin, with low nutrient reserves and unreasonable distribution; second, there is an obstacle layer, albic layer, in the soil structure. This layer has a dense structure and high hardness, resulting in shallow soil water storage capacity, poor permeability, and imbalance of soil water, fertilizer, air and heat. This leads to serious problems of surface drought and surface waterlogging, becoming a major bottleneck problem hindering crop production.

[0003] Ordinary deep tillage machinery struggles to break through the hard silt layer, and fertilization depth cannot reach the subsoil layer, making it difficult to improve the physical and chemical properties of the subsoil. When the soil around fruit trees becomes silty during their growth, it affects the normal growth of the fruit trees. To ensure the normal growth of fruit trees, it is necessary to improve the silty soil around them. However, large-scale tillage machinery cannot enter the area around the fruit trees to till the soil, and large-scale tillage around the fruit trees can also affect the root stability of the fruit trees. Therefore, it is not feasible to use large machinery to till the soil around the fruit trees. A device is needed to improve the silty soil around fruit trees. Summary of the Invention

[0013] A method for improving alkaline soil, applicable to the aforementioned improvement apparatus, further comprising the following steps:

[0015] Step 2: Start the third rotary motor to drive the rotating tube to rotate, start the second rotary motor to drive the lead screw to rotate, drive the lifting plate to move downward, the squeezing rod and the first auger blade enter the soil layer, and drive the first stirring plate into the white clay soil layer;

[0018] Step 5: The connecting rod moves to the hopper and rotates to agitate the soil-improving material.

[0019] The beneficial effects of this invention are reflected in:

[0020] In this invention, a rotating tube and a rotating connecting rod are provided. The rotating tube drives the first stirring plate to extend to the white soil layer and rotate, which can complete the stirring of the white soil layer and destroy its structure. Through the rotation of the rotating connecting rod, the soil improvement material can be discharged from the discharge slot to the soil layer through the second auger blade. Combined with the rotation of the first and second stirring plates, the soil improvement material and the white soil layer can be mixed, thereby increasing the efficiency and effect of soil improvement.

[0021] By rotating the tube to change its position in the soil layer, it is also possible to deliver soil improvement materials between different soil layers.

[0022] By having the second electric slider slide in the second chute, the second stirring plate moves away from the first stirring plate, which increases the stirring range of the first stirring plate on the white soil layer and also increases the mixing rate of the soil improvement material and the white soil layer.

[0023] In this invention, a connecting rod is provided that extends into the material inside the hopper. Then, a first rotating motor drives a rotating disk to rotate, so that the connecting rod can agitate the material in the hopper. This operation method can prevent the material from accumulating in the hopper and affecting the normal feeding of the material.

[0024] The auxiliary block extends into the interior of the first slot. A laser rangefinder sensor measures the distance to the rotating tube and transmits the measured distance value to the background control system for comparison with the standard distance value. If the detected distance value exceeds the standard distance value range, it indicates that the rotating tube has deformed, thus completing the deformation detection of the rotating tube.

These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0047] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by those skilled in the art to which this invention pertains.

A feeding mechanism is located on the top of the lifting plate 2, and a mixing mechanism is located on the bottom of the lifting plate 2. A rotating rod 6 is movably connected to one side of the workbench 1, and an auxiliary mechanism is provided on the rotating rod 6. The feeding mechanism enables precise feeding of the soil improvement material into the alkaline soil layer. The mixing mechanism mixes the soil in the alkaline soil layer with the soil improvement material.

The lead screw 29 is threaded through the sliding block 27, and the sliding block 27 is connected to the lifting plate 2 on the side facing the lifting plate 2. A second rotary motor 28 is installed on the top of the support rod 4, and the output end of the second rotary motor 28 is movably connected to the lead screw 29 through the top of the support rod 4. By rotating the lead screw 29 through the second rotary motor 28, the sliding block 27 can be raised and lowered on the support rod 4 according to different usage requirements, thereby raising and lowering the lifting plate 2.

[0050] As a technical optimization solution in this invention, the feeding mechanism includes a hopper 3, and a lifting plate 2 with multiple discharge ports 30 extending through the center of the bottom of the hopper 3. The bottom of the hopper 3 is inclined around the discharge ports 30. The inclined design of the bottom of the hopper 3 allows the soil-improving material to fall into the discharge ports 30 under the action of gravity.

[0051] As a technical optimization of the present invention, the stirring mechanism includes a rotating tube 5, a first stirring plate 31, a pressing rod 32, and a first auger blade 33. The rotating tube 5 is rotatably mounted on the bottom of the lifting plate 2. The pressing rod 32 is connected to the bottom of the rotating tube 5. The bottom of the pressing rod 32 is tapered. The first auger blade 33 is provided on the outer side of the pressing rod 32. Multiple first stirring plates 31 are evenly arranged on the outer side of the rotating tube 5 above the first auger blade 33. A third slot 46 is opened on the side of the first stirring plate 31 away from the rotating tube 5. A second sliding groove 47 is opened on both inner walls of the third slot 46. A second stirring plate 45 is slidably installed inside the third slot 46. A second electric slider 48 is connected to both sides of the second stirring plate 45. The second electric slider 48 is slidably installed inside the second sliding groove 47. The tapered design at the bottom of the extrusion rod 32 allows it to enter the soil layer more smoothly. The design of the first auger blade 33 allows the rotating tube 5 to more easily drive the first stirring plate 31 into the white clay layer. The second stirring plate 45 can extend and retract in the first stirring plate 31 according to different usage requirements by sliding the second electric slider 48 in the second groove 47.

[0052] As a technical optimization in this invention, a rotating groove 49 is provided at the bottom of the lifting plate 2 near the rotating tube 5. A rotating component 38 (which can be a bearing) is rotatably installed inside the rotating groove 49. A second gear 37 is connected to the bottom of the rotating component 38. The second gear 37 is sleeved on the top outer side of the drilling tube 5. L-shaped support plates 34 are installed on both sides of the lifting plate 2. A third rotary motor 35 is installed on the top of the L-shaped support plates 34. The output end of the third rotary motor 35 faces upward and is connected to a first gear 36. The first gear 36 meshes with the second gear 37, and the top of the first gear 36 is rotatably connected to the bottom of the lifting plate 2. By driving the first gear 36 to rotate through the third rotary motor 35, the second gear 37 can be driven to rotate, thereby driving the rotating tube 5 to rotate according to different usage requirements, completing the mixing of the white clay layer and the soil improvement material.

[0053] As a technical optimization of the present invention, the inner wall opening of the rotating tube 5 is connected to the discharge port 30. The rotating tube 5 is provided with a rotating connecting rod 39. The bottom of the lifting plate 2 is embedded with a drive motor 51. The output end of the drive motor 51 faces downward and is connected to the top of the rotating connecting rod 39. The bottom of the rotating connecting rod 39 is connected to the top of the extrusion rod 32. The outer side of the rotating connecting rod 39 is provided with a second auger blade 40. The bottom of the rotating tube 5 is provided with two discharge slots 41 near the first stirring plate 31. The top inner wall of the discharge slot 41 is provided with a second slot 43. The discharge baffle 42 is slidably installed inside the second slot 43. The top of the discharge baffle 42 is connected to a second electric lifting rod 44. The mounting end of the second electric lifting rod 44 faces upward and is connected to the top of the inner wall of the second slot 43. The drive motor 51 can drive the rotating connecting rod 39 to rotate according to different usage requirements, so that the second auger blade 40 can transport the soil improvement material. The second electric lifting rod 44 drives the discharge baffle 42 to rise and fall, and can control the opening and closing of the discharge slot 41, so that the soil improvement material can be discharged from the discharge slot 41.

[0054] As a technical optimization in this invention, a movable slide groove 7 is provided on one side of the workbench 1. A movable electric slider 8 is slidably installed inside the movable slide groove 7. A connector 9 is connected to the side of the movable electric slider 8 away from the workbench 1. The side of the connector 9 away from the workbench 1 has a groove design. A rotating block 10 is rotatably connected inside the groove of the connector 9 via an electric rotating shaft. A first rotary motor 19 is embedded in the top of the rotating block 10, with the output end of the first rotary motor 19 facing upwards. The bottom of the rotating rod 6 is connected to the output end of the first rotary motor 19. By sliding the movable electric slider 8 in the movable slide groove 7, the connector 9 can be moved to the side of the workbench 1 according to different usage requirements. The electric rotating shaft in the connector 9 can drive the rotating block 10 to rotate according to different usage requirements. The first rotary motor 19 can drive the rotating rod 6 to rotate according to different usage requirements.

[0055] As a technical optimization of the present invention, the auxiliary mechanism includes a first electric lifting rod 14 and a connecting rod 18. A displacement groove 11 is provided on the side of the rotating rod 6 facing the worktable 1. A displacement electric slider 12 is slidably installed inside the displacement groove 11. An electric telescopic rod 13 is connected to the side of the displacement electric slider 12 away from the rotating rod 6. The telescopic end of the electric telescopic rod 13 is away from the rotating rod 6. A connecting block 15 is connected to the telescopic end of the electric telescopic rod 13. The first electric lifting rod 14 is installed on the top of the connecting block 15. A lifting block 16 is provided at the bottom of the connecting block 15. The lifting end of the first electric lifting rod 14 movably passes through the top of the connecting block 15 and connects to the lifting block 16. A first rotating motor 20 is embedded in the bottom of the lifting block 16. The output end of the first rotating motor 20 faces downward and is connected to a rotating disk 17. Multiple connecting rods 18 are evenly connected along the circumferential direction on the outer circumferential wall of the rotating disk 17. A blade is provided on the outer side of the connecting rod 18. By sliding the displacement slider 12 in the displacement groove 11, the electric telescopic rod 13 can be driven to rise and fall on the rotating rod 6 according to different usage requirements. The electric telescopic rod 13 can drive the connecting block 15 to extend. The first electric lifting rod 14 can drive the lifting block 16 to rise and fall.

[0056] As a technical optimization in this invention, a first slot 21 is formed on the outer wall of the connecting rod 18, and first sliding grooves 23 are formed on the inner walls of both sides of the first slot 21. A first electric slider 24 is slidably installed inside the first sliding groove 23, and an auxiliary block 22 is slidably installed inside the first slot 21. The side of the auxiliary block 22 closest to the first electric slider 24 is connected to the first electric slider 24, and a laser rangefinder 25 is embedded in the side of the auxiliary block 22 facing the worktable 1. By allowing the first electric slider 24 to slide in the first sliding groove 23, the auxiliary block 22 can be raised and lowered in the first slot 21 according to different usage requirements, thus protecting the laser rangefinder 25 when it is not in use.

[0057] A method for improving alkaline soil, applicable to the aforementioned improvement apparatus, further comprising the following steps:

[0058] Step 1: Preparation. Move workbench 1 to the soil around the fruit tree and add the soil amendment material into hopper 3.

[0059] Step 2: Start the third rotary motor 35 to drive the rotating tube 5 to rotate, start the second rotary motor 28 to drive the lead screw 29 to rotate, drive the lifting plate 2 to move downward, the squeezing rod 32 and the first auger blade 33 enter the soil layer, and drive the first stirring plate 31 into the white clay layer.

[0060] Step 3: The second electric lifting rod 44 drives the discharge baffle 42 to move upward, opening the discharge slot 41. The drive motor 51 is started to drive the rotating connecting rod 39 to rotate, and the second auger blade 40 discharges the material from the discharge slot 41.

[0061] Step 4: The second stirring plate 45 extends outward to stir the soil amendment material and the white clay.

[0062] Step 5: The connecting rod 18 moves to the feeding hopper 3 and rotates to agitate the soil-modifying material.

[0063] In use, the electric drive mechanisms used in this device are all powered by wires connected to a power source. The device controls the electrical equipment through a preset control system. The laser rangefinder 25 used in this device is a mature existing technology, so it will not be described in detail. The moving wheels used in this device are electrically driven wheels, which are also mature existing technology, so they will not be described in detail. The worker adds crushed soil-improving materials such as crop straw and organic fertilizer into the hopper 3. Soil-improving materials are also mature existing technology, so they will not be described in detail. By driving the rotating connecting rod 39 to rotate through the drive motor 51, the material added to the hopper 3 can fall from the discharge port 30 and be conveyed downwards to the rotating tube 5 as the second auger blade 40 rotates. The size of the discharge port 30 is larger than the size of the crushed material added to the hopper 3.

[0064] When it is necessary to improve the alkaline soil around the fruit trees, it is not possible to use large machinery to treat the soil around the fruit trees, nor is it possible to completely turn over the soil. Therefore, when it is necessary to stir the alkaline soil around the fruit trees, the workbench 1 is moved to the soil around the fruit trees, and then the third rotary motor 35 is started, which drives the first gear 36 to rotate, which in turn drives the second gear 37 to rotate, thereby driving the rotating tube 5 to rotate. At the same time, the second rotary motor 28 drives the lead screw 29 to rotate, so that the sliding block 27 can slide inside the sliding groove 26, thereby driving the lifting plate 2 to move downward, so that the bottom of the rotating tube 5 can extend into the soil layer plate through the rotation of the first auger blade 33, until the first stirring plate. 31 extends into the white soil layer. At this time, under the rotation of the rotating pipe 5, the first stirring plate 31 can stir the white soil layer. By retracting the second electric lifting rod 44, the discharge baffle 42 is driven to move upward until the discharge slot 41 opens. At this time, the rotating connecting rod 39 rotates, and the material in the discharge hopper 3 is conveyed to the outside of the rotating pipe 5 through the discharge slot 41. By combining this operation method with the lifting and lowering of the rotating pipe 5 at different positions in the soil layer, the soil improvement material can be accurately conveyed to different soil layer positions. By sliding the second electric slider 48 in the second chute 47, the second stirring plate 45 moves away from the first stirring plate 31, which can increase the stirring range of the first stirring plate 31 on the white soil layer, and at the same time increase the mixing rate of the soil improvement material and the white soil layer.

[0065] The electric telescopic rod 13 drives the connecting block 15 to extend towards the hopper 3. When the connecting rod 18 extends to the upper use position inside the hopper 3, the first electric lifting rod 14 drives the lifting block 16 to extend downward, so that the connecting rod 18 extends into the material inside the hopper 3. Then, the first rotating motor 20 drives the rotating disk 17 to rotate, so that the connecting rod 18 can stir the material in the hopper 3. Through this operation, the material in the hopper 3 can be prevented from accumulating and affecting the normal feeding of the material.

[0066] The first rotary motor 19 drives the rotating rod 6 to rotate, causing the connecting block 15 to rotate to the side away from the hopper 3. Then, the electric rotating shaft inside the adapter 9 drives the rotating rod 6 to rotate to the downward working state. Next, the connecting block 15 rotates again to the working direction facing the worktable 1. At this time, the first electric slider 24 slides in the first groove 23, causing the auxiliary block 22 to extend out of the first slot 21. At this time, the laser range sensor 25 measures the distance of the rotating tube 5 and transmits the measured distance value to the background control system for comparison with the standard distance value. If the detected distance value exceeds the standard distance value range, it indicates that the rotating tube has deformed. This detection method can effectively prevent the reduction of the efficiency of soil improvement material delivery inside the rotating tube 5 due to deformation of the rotating tube 5 itself, and prevent the rotating tube 5 from swinging during its rotation after deformation, causing excessive meshing of the first gear 36 and the second gear 37, resulting in damage to the teeth and affecting the stirring of the white soil by the device.

[0067] This device uses multiple drilling operations around the soil surrounding the fruit trees to improve the albic soil. During the soil improvement process, rotating the connecting rod 18 downwards, combined with the rotation of the rotating disk 17 driven by the first rotating motor 20, allows the blades on the outside of the connecting rod 18 to clear weeds around the fruit trees. This facilitates the movement of the device around the fruit trees and the soil improvement work, increasing its ease of use. Furthermore, using a mixture of crushed waste straw and organic fertilizer as the soil improvement material results in low cost, more lasting improvement effects, and minimizes damage to the upper black soil layer during soil improvement.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
