Description

Technical Field

[0001] The present invention relates to the field of agricultural machinery, and in particular to an organic-inorganic combined precise deep tillage and fertilization device and method. Background Art

[0002] Soil organic matter and carbon have a crucial impact on the physical, chemical, and biological properties of soil. Soil organic matter is an important material foundation for soil fertility. It improves soil structure, increases soil water and nutrient retention, promotes soil microbial activity, and provides sufficient nutrients for crop growth. Carbon, as a source of energy for various biochemical reactions in the soil, plays a key role in maintaining the balance and stability of the soil ecosystem. When soil organic matter and carbon are deficient, the soil gradually becomes compacted, with reduced aeration and water permeability. This restricts crop root growth and prevents the effective absorption of water and nutrients, directly affecting crop yield and quality. For example, in corn cultivation, soil problems can lead to poor root growth and reduced absorption capacity, resulting in stunted growth and declining yields.

[0003] In order to solve the problem of soil fertility, fertilization is a common and effective means. Most of the fertilization equipment currently available on the market is a spreading device. Although these spreading devices can spread fertilizer on the soil surface, they have obvious limitations. They can only carry out surface fertilization and cannot apply fertilizer deeply into the soil. However, the soil in the Northwest region is severely compacted. If fertilizer cannot penetrate deeply into the soil, it is difficult for it to be fully absorbed by the roots of crops. Most of the fertilizer will be lost due to surface runoff and volatilization, which not only reduces the utilization efficiency of fertilizer, but also fails to achieve the effect of synergistic improvement of soil fertility through tillage and fertilization.

[0004] In addition, existing fertilization machinery usually does not have the function of deep tillage with a deep plowing shovel. Deep tillage is of great significance for improving soil structure and increasing soil fertility. Through deep tillage, the soil compaction layer can be broken, the air permeability and water permeability of the soil can be increased, and good soil conditions can be created for the growth and development of crop roots. The roots can better stretch in the loose soil, thereby absorbing water and nutrients more effectively. At the same time, deep tillage can also promote the activity of soil microorganisms, accelerate the decomposition of organic matter in the soil, and further improve soil fertility. However, existing fertilization equipment is unable to perform this critical preliminary operation, and it is difficult to fundamentally solve the problems of soil compaction and low fertilizer absorption and utilization rate in the Northwest.

[0005] Furthermore, existing equipment struggles to combine organic and chemical fertilizers in fertilization. The long-term, heavy use of chemical fertilizers can lead to further deterioration in soil quality, while organic fertilizers have the advantages of improving soil structure and increasing soil organic matter content. Combining organic and chemical fertilizers can ensure nutrient availability for crops while reducing the use of chemical fertilizers, achieving green fertilization and protecting the soil ecosystem in Northwest China. However, existing fertilization equipment has technical shortcomings in this regard and cannot meet the needs of sustainable agricultural development.

[0006] In summary, there is an urgent need for a new fertilization device and method that can integrate deep tillage and soil improvement with precise application of organic and chemical fertilizers to improve soil fertility, ensure crop yield and quality, and promote the sustainable development of dryland agriculture. Therefore, we propose a combined organic and inorganic precise deep tillage and fertilization device and method. Summary of the Invention

[0007] The purpose of the present invention is to address the problems raised by the existing background technology. In order to achieve the above-mentioned invention purpose, the present invention provides the following technical solutions: an organic-inorganic combined precision deep loosening and fertilizing device, comprising a device frame, and a frame hanging rod arranged at the front end of the device frame, a supporting longitudinal rod is installed between the device frame and the frame hanging rod, wherein an adjusting hydraulic cylinder is installed on the shaft on the inner side of the frame hanging rod, a telescopic hydraulic rod is embedded in the adjusting hydraulic cylinder, and a linkage shaft is connected between the supporting longitudinal rod and the telescopic hydraulic rod, and a stabilizing diagonal rod is fixed on the other side of the supporting longitudinal rod.

[0008] As a preferred technical solution of the present invention, wheel mounting frames are embedded below the four corners of the device frame, and four wheel mounting frames are provided, and a buffer spring is connected to each wheel mounting frame.

[0009] As a preferred technical solution of the present invention, a first loosening wheel and a second loosening wheel are provided below the wheel body mounting frame.

[0010] As a preferred technical solution of the present invention, a corn fertilizer box is fixed above the device frame, a front fertilizer box discharge hopper is installed on the right half of the corn fertilizer box, and a rear fertilizer box discharge hopper is connected to the left half of the corn fertilizer box.

[0011] As a preferred technical solution of the present invention, a fertilizer diverter box is provided on one side of the front fertilizer box discharge hopper and the rear fertilizer box discharge hopper, and a diverter rotor is embedded in the fertilizer diverter box.

[0012] As a preferred technical solution of the present invention, a linkage rod is provided in the center of the material-diverting rotor, and both sides of the linkage rod pass through the two walls of the fertilizer diverting box, and a front fertilizer discharge pipe and a rear fertilizer discharge pipe are installed in the lower entrance of the fertilizer diverting box.

[0013] As a preferred technical solution of the present invention, a loosening rod is fixed to the front end of the rear fertilizer discharge pipe, and the loosening rod is located at the front end of the second loosening wheel.

[0014] As a preferred technical solution of the present invention, device hubs are provided on both sides of the device frame, a rotating shaft is embedded in the center end of the device hub, and the other end of the rotating shaft is connected to the device frame, and a moving wheel is embedded in the outer surface of the device hub.

[0015] A method for using an organic-inorganic combined precise deep loosening and fertilization device comprises the following steps: Step 1, adding fertilizer: opening a corn fertilizer box, and adding organic fertilizer or chemical fertilizer, or a combination of the two, to the corn fertilizer box according to planting requirements and soil fertility;

[0016] Step 2: Connect the device to the traction equipment through the rack hanging rod to ensure a firm connection;

[0017] Step 3, device inspection: Check whether the buffer spring is properly installed in the wheel body mounting frame to ensure that it has the buffering and shock absorption function; check whether the feeding rotor can rotate flexibly in the fertilizer feeding box, and whether the linkage rod passes through the two walls of the fertilizer feeding box and is properly connected; check and adjust the hydraulic cylinder and the telescopic hydraulic rod to ensure that they can work normally;

[0018] Step 4. Adjust the depth of deep plowing: Start the hydraulic cylinder, adjust the telescopic length of the telescopic hydraulic rod, drive the supporting longitudinal rod through the linkage shaft, and adjust the depth of the deep plowing shovel into the soil;

[0019] Step 5. Adjust the amount of fertilizer: According to the actual needs of corn planting and soil fertility, the amount of fertilizer is adjusted by controlling the speed of the feeding rotor. The faster the feeding rotor speed, the more fertilizer is discharged through the front and rear fertilizer discharge pipes. The speed of the feeding rotor can be adjusted by changing the transmission ratio of the linkage rod or the power input method.

[0020] Step 6: Deep tillage and plowing: Start the traction equipment to drive the device forward; during the forward movement of the device, the deep tillage shovel performs deep tillage and plowing operations on the soil;

[0021] Step 7: Soil loosening: The first and second loosening wheels further loosen the soil after deep loosening as the device moves forward, making the soil more fine-grained and creating good soil conditions for subsequent fertilization and corn planting. At the same time, the loosening rod at the front end of the rear fertilizer discharge pipe will also assist in loosening the soil to ensure that the fertilizer can enter the soil smoothly.

[0022] Step 8, precise fertilization: The fertilizer in the corn fertilizer box enters the corresponding fertilizer dispensing box through the front fertilizer box discharge hopper and the rear fertilizer box discharge hopper respectively;

[0023] The feeding rotor rotates under the drive of the linkage rod, feeding the fertilizer into the front fertilizer discharge pipe and the rear fertilizer discharge pipe. The fertilizer penetrates into the soil after deep tillage through the discharge pipe for fertilization.

[0024] Step 9. Finishing work: After the operation is completed, turn off the traction equipment and related power sources.

[0025] As a preferred technical solution of the present invention, it also includes equipment cleaning: cleaning the remaining fertilizer in the corn fertilizer box to prevent the fertilizer residue from corroding the equipment, cleaning the soil adhering to the deep loosening shovel, the first loosening wheel, the second loosening wheel, and the loosening rod components to keep the equipment clean.

[0026] Compared with existing technologies, the present invention offers the following advantages: By controlling the speed of the feeding rotor to adjust the amount of fertilizer applied, precise fertilization can be achieved based on the differences in soil fertility and corn planting density in different plots. This avoids the problems of excessive fertilizer application or uneven fertilizer distribution in traditional fertilization methods, allowing fertilizer to be applied more precisely around the corn root system, improving fertilizer utilization and reducing fertilizer waste and environmental pollution.

[0027] The device is equipped with a deep tillage blade to perform deep tillage before fertilizing. This process breaks up the soil's compacted layer, increasing its aeration and water permeability, which is beneficial for the growth and development of corn roots and allows them to better absorb water and nutrients. Deep tillage also promotes soil microbial activity, accelerates the decomposition of organic matter, and improves soil fertility.

[0028] The first and second loosening wheels, along with the loosening bar, perform multi-stage loosening of the soil after deep loosening. This further fragments the soil, allowing fertilizer to be more evenly incorporated into the soil and creating a favorable soil environment for corn seed germination and growth. Loose soil also facilitates the infiltration and retention of rainwater, improving the soil's drought resistance.

[0029] Adjusting the hydraulic cylinder and telescopic hydraulic rod allows for easy adjustment of the subsoiler's penetration depth. This flexibility allows the device to adapt to various soil types, planting requirements, and operating depth requirements, enhancing its versatility and applicability.

[0030] The buffer springs within the wheel mounting frame effectively dampen vibrations during operation, reducing damage to components and extending the equipment's service life. This also ensures smooth operation, making fertilization and deep tillage operations more precise and efficient.

[0031] The device connects to the traction equipment via a rack-mounted rod. This simple and stable connection facilitates use with common agricultural traction equipment, such as tractors. The device hubs, rotating shafts, and moving wheels on both sides of the device allow for flexible movement when driven by the traction equipment, facilitating transfers between different plots of land and improving operational efficiency.

It should be noted that similar numbers and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0041] Example 1: An organic-inorganic combined precision deep tillage and fertilization device, comprising a device frame 1, and a frame hanging rod 2 arranged at the front end of the device frame 1, a supporting longitudinal rod 3 is installed between the device frame 1 and the frame hanging rod 2, wherein an adjusting hydraulic cylinder 4 is installed on the shaft on the inner side of the frame hanging rod 2, and a telescopic hydraulic rod 5 is embedded and connected inside the adjusting hydraulic cylinder 4, and a linkage shaft 6 is connected between the supporting longitudinal rod 3 and the telescopic hydraulic rod 5, and a stabilizing diagonal rod 7 is fixed on the other side of the supporting longitudinal rod 3. Wheel body mounting frames 8 are embedded below the four corners of the device frame 1, and there are four wheel body mounting frames 8, each of which is connected to a buffer spring 20. A first soil-dispersing wheel 9 and a second soil-dispersing wheel 10 are provided below the wheel body mounting frame 8. A corn fertilizer box 11 is fixed above the device frame 1, and a front fertilizer box discharge hopper 12 is installed on the right half of the corn fertilizer box 11, while a rear fertilizer box discharge hopper 13 is connected to the left half of the corn fertilizer box 11.

[0042] A fertilizer dispensing box 14 is located on one side of both the front fertilizer bin discharge hopper 12 and the rear fertilizer bin discharge hopper 13. A dispensing rotor 15 is embedded within the dispensing box 14. A linkage rod 16 is positioned within the center of the dispensing rotor 15. The linkage rod 16 extends through the walls of the dispensing box 14. A front fertilizer dispensing pipe 17 and a rear fertilizer dispensing pipe 18 are installed within the lower entrance of the dispensing box 14. A soil-dispensing rod 19 is fixed to the front end of the rear fertilizer dispensing pipe 18, located at the front end of the second soil-dispensing wheel 10.

[0043] Device hubs 21 are provided on both sides of the device frame 1 . A rotating shaft 22 is embedded in the center end of the device hub 21 , and the other end of the rotating shaft 22 is connected to the device frame 1 . A moving wheel 23 is embedded in the outer surface of the device hub 21 .

[0044] Working principle of the precision fertilization device for green corn production: The device is mainly connected to an external traction device such as a tractor through a frame hanging rod 2, and relies on the traction device to provide forward power, so that the entire device can move and operate in the corn planting area.

[0045] Principle of deep tillage:

[0046] As the device advances, the subsoiler 24 on the front of the frame 1 plays a key role. A telescopic hydraulic rod 5 inside the hydraulic cylinder 4 allows for telescopic adjustment and is connected to the supporting longitudinal rod 3 via a linkage shaft 6. When the hydraulic cylinder 4 is in operation, the telescopic hydraulic rod 5's extension and retraction drive the angle of the supporting longitudinal rod 3, thereby adjusting the penetration depth of the subsoiler 24. As the device advances, the subsoiler 24 cuts into the soil, performing a deep tillage operation. This breaks down compacted soil layers, increases soil aeration and water permeability, and creates a favorable soil environment for corn root growth and fertilizer penetration.

[0047] Soil loosening principle:

[0048] Buffer springs 20 are installed within the wheel mounting frames 8 at the four corners of the device frame 1 to provide cushioning and shock absorption, ensuring smooth operation on uneven surfaces. The first and second loosening wheels 9, 10 below the wheel mounting frames 8 rotate as the device advances, further loosening the subsoiled soil and reducing its particles. A loosening rod 19 at the front of the rear fertilizer discharge pipe 18 also assists in loosening the soil as the device advances, ensuring that soil conditions are suitable for fertilizer application and corn seed planting.

[0049] Principles of fertilizer delivery and precision fertilization:

[0050] Fertilizer storage: The corn fertilizer box 11 is used to store organic fertilizer or chemical fertilizer, or a mixture of the two, to provide a fertilizer source for fertilization operations.

[0051] Fertilizer discharge: The front fertilizer box discharge hopper 12 on the right half and the rear fertilizer box discharge hopper 13 on the left half of the corn fertilizer box 11 can guide the fertilizer to the corresponding fertilizer transfer box 14 respectively.

[0052] Fertilizer feeding: The feeding rotor 15 inside the fertilizer feeding box 14 rotates driven by a linkage rod 16. Linkage rod 16 extends through the walls of the fertilizer feeding box 14. An external power source, such as a motor or transmission, drives linkage rod 16, which in turn drives the feeding rotor 15. The rotation of feeding rotor 15 feeds fertilizer from the fertilizer feeding box 14 into the front and rear fertilizer discharging pipes 17 and 18 below.

[0053] Precision Fertilization: Fertilizer is delivered to the soil after deep tillage through the front and rear fertilizer discharge pipes 17 and 18. By controlling the speed of the feeding rotor 15, the fertilizer discharge rate can be adjusted, achieving precise fertilization to meet the fertilizer needs of corn at different growth stages and soil fertility conditions.

[0054] Device movement principle:

[0055] The center ends of the device hubs 21 on both sides of the device frame 1 are embedded in the rotating shafts 22, and the other ends of the rotating shafts 22 are connected to the device frame 1. The outer surfaces of the device hubs 21 are embedded with moving wheels 23. Driven by the traction equipment, the moving wheels 23 rotate, allowing the entire device to move on the ground to complete a series of operations such as deep loosening, soil loosening and fertilization.

[0056] The working process of the precision fertilization device for green corn production mainly includes the preparation stage, the operation stage and the end stage:

[0057] Preparation stage:

[0058] Fertilizer filling: According to the specific needs of corn planting and the results of soil fertility test, determine the use of organic fertilizer, chemical fertilizer or a mixture of the two. Open the feeding port of the corn fertilizer box 11 and add the selected fertilizer into the box.

[0059] The device is securely connected to a traction device such as a tractor via a frame hanging rod 2 .

[0060] Check the installation of the buffer spring 20 in the wheel mounting frame 8 to ensure that it can play a normal buffering role; check whether the material rotor 15 can rotate flexibly in the fertilizer material box 14 and whether the connection of the linkage rod 16 is stable.

[0061] Start the regulating hydraulic cylinder 4, test the telescopic function of the telescopic hydraulic rod 5, adjust the supporting longitudinal rod 3 through the linkage shaft 6, and then set the appropriate soil penetration depth of the deep plowing shovel 24 to adapt to different soil conditions and planting requirements.

[0062] According to the preset fertilizer application amount, the speed of the feeding rotor 15 is adjusted. This can be achieved by changing the transmission ratio or power input mode of the linkage rod 16 to ensure that the fertilizer discharge amount meets the precise needs of corn planting.

[0063] Marching operation phase:

[0064] The traction device is started and the device moves forward. The subsoiler 24 cuts into the soil during movement, performing deep loosening operations on the soil, breaking up the soil compaction layer, improving the soil's air permeability and water permeability, and creating a good soil environment for subsequent fertilization and corn root growth.

[0065] The first and second loosening wheels 9 and 10 follow the device forward to further loosen and refine the soil after deep loosening. At the same time, the loosening rod 19 at the front end of the rear fertilizer discharge pipe 18 also assists in loosening the soil to ensure a uniform soil texture, which is conducive to the uniform distribution of fertilizer and the implantation of corn seeds.

[0066] The fertilizer in the corn fertilizer box 11 flows into the corresponding fertilizer dispensing box 14 through the front fertilizer box discharge hopper 12 and the rear fertilizer box discharge hopper 13 under the action of gravity.

[0067] Driven by the linkage rod 16, the feeding rotor 15 rotates continuously, evenly feeding the fertilizer into the front fertilizer discharge pipe 17 and the rear fertilizer discharge pipe 18. The fertilizer is accurately delivered to the soil after deep tillage through the discharge pipe, achieving deep fertilization and improving fertilizer utilization.

[0068] Ending the closing phase:

[0069] After completing the fertilization operation, shut down the traction equipment and related power sources, and stop the device. Open the discharge port of the corn fertilizer tank 11 and clean out any remaining fertilizer inside to prevent corrosion. Rinse the subsoiler 24, first and second loosening wheels 9, 10, and loosening bar 19 with clean water or a specialized detergent to remove any adhering soil and fertilizer.

[0070] Store the device in a dry, ventilated warehouse to prevent it from getting damp and rusting.

[0071] Check the wear and tear of each component, such as whether the cutting edge of the subsoiler 24 is worn or whether the blade of the material-digging rotor 15 is damaged. For severely worn components, replace or repair them in time.

[0072] Add lubricating oil to rotating parts such as the linkage rod 16 and the rotating shaft 22 to ensure smooth rotation and extend the service life of the equipment.

[0073] In summary, the precise fertilization device for green corn production realizes the functions of soil loosening, precise transportation and discharge of fertilizers through the coordinated work of various components, thereby achieving the purpose of precise fertilization for green corn production.

[0150] main_control(terrain_type,corn_growth_stage,soil_fertility)

[0151] Algorithm explanation:

[0152] Device initialization: The connect_and_check_device function simulates connecting the device to the tractor power equipment and checks the status of each component to ensure that the device can work normally.

[0153] Height and angle adjustment: The adjust_height_and_angle function adjusts the height and angle of the device according to the terrain type (flat or sloped) to adapt to different working environments.

[0154] Fertilizer amount calculation and control: The set_fertilizer_amount function calculates the required fertilizer amount based on the corn growth stage and soil fertility, and controls the fertilizer amount by adjusting the speed of the feeding rotor.

[0155] Soil loosening: The loosen_soil function starts the power equipment to make the first and second loosening wheels loosen the soil.

[0156] Fertilizer delivery and discharge: The deliver_fertilizer function simulates the process of fertilizer entering the fertilizer transfer box from the fertilizer box and being transferred out, and the discharge_fertilizer function simulates the process of fertilizer being discharged into the soil through the fertilizer discharge pipe.

[0157] Operation stop and equipment cleaning: The stop_operation function shuts down the power equipment and stops the rotation of the feeding rotor. The clean_device function cleans the equipment to prevent the fertilizer from clumping and clogging the pipe.

[0158] The method of using the device for precise fertilization of corn green production is to firmly connect the device to the tractor power equipment through the frame hanging rod 2, ensuring that the connection part is firm and can ensure that the device can stably follow the movement of the power equipment during operation;

[0159] Perform a comprehensive inspection of all components of the device; check whether the device frame 1 is damaged or deformed; check whether the connecting parts of the supporting longitudinal rod 3 and the stabilizing diagonal rod 7 are loose; confirm that the buffer spring 20 in the wheel body mounting frame 8 is intact, and the first and second loosening wheels 9 and 10 rotate flexibly without any jamming;

[0160] According to the terrain of the working plot and the actual fertilization needs, the hydraulic cylinder 4 is activated and adjusted; the hydraulic cylinder 4 drives the telescopic hydraulic rod 5 to extend and retract, and the telescopic hydraulic rod 5 drives the supporting longitudinal rod 3 to move through the linkage shaft 6, thereby adjusting the height and angle of the device; on flat plots, the height of the device can be appropriately lowered to make the soil wheel and the fertilizer discharge pipe closer to the ground; on sloped plots, the angle is adjusted to ensure uniform fertilization;

[0161] Add an appropriate amount of fertilizer that meets the growth requirements of corn into the corn fertilizer box 11; manually rotate the feeding rotor 15 to observe the discharge of fertilizer from the discharge hopper through the fertilizer discharge pipe; by adjusting the speed of the power source connected to the linkage rod 16, the speed of the feeding rotor 15 is changed to control the amount of fertilizer;

[0162] The power equipment is started, and the device begins to move forward under the rotation of the moving wheel 23; the first loosening wheel 9 and the second loosening wheel 10 loosen the soil preliminarily as the device moves, thereby destroying the compacted layer of the soil;

[0163] As the device continues to move forward, the fertilizer in the corn fertilizer box 11 enters the fertilizer diverter box 14 through the front fertilizer box discharge hopper 12 and the rear fertilizer box discharge hopper 13 under the action of gravity; the power source drives the linkage rod 16 to rotate, thereby causing the diverter rotor 15 to rotate in the fertilizer diverter box 14; the diverter rotor 15 evenly diverts the fertilizer that falls into the fertilizer diverter box 14, thereby achieving preliminary quantitative control of the fertilizer;

[0164] The fertilizer after being moved by the feeding rotor 15 enters the front fertilizer discharging pipe 17 and the rear fertilizer discharging pipe 18, and is discharged into the soil from the discharging pipes; the loosening rod 19 at the front end of the rear fertilizer discharging pipe 18 further loosens the soil before the fertilizer is discharged;

[0165] When the fertilizing operation is completed, the power equipment is turned off and the device stops moving forward; at the same time, the rotation of the material-dispensing rotor 15 is stopped and the fertilizer supply is cut off.

[0166] Open the corn fertilizer box 11, clean out the remaining fertilizer and store it properly; rinse the fertilizer discharge pipe and fertilizer box components with clean water to remove the residual fertilizer and prevent the fertilizer from clogged in the pipe; clean the dirt and debris on the first soil wheel 9, the second soil wheel 10 and the soil rod 19.

[0167] A method for using an organic-inorganic combined precise deep loosening and fertilization device comprises the following steps: Step 1, adding fertilizer: opening a corn fertilizer box 11, and adding organic fertilizer or chemical fertilizer, or a combination of the two, into the corn fertilizer box 11 according to planting requirements and soil fertility;

[0170] Step 4, deep plowing depth adjustment: start the adjustment hydraulic cylinder 4, adjust the telescopic length of the telescopic hydraulic rod 5, drive the supporting longitudinal rod 3 through the linkage shaft 6, and adjust the depth of the deep plowing shovel 24 into the soil;

[0171] Step 5: Adjusting the amount of fertilizer: According to the actual needs of corn planting and soil fertility, the amount of fertilizer is adjusted by controlling the speed of the paddle rotor 15; the faster the speed of the paddle rotor 15, the more fertilizer is discharged through the front fertilizer discharge pipe 17 and the rear fertilizer discharge pipe 18; the speed of the paddle rotor 15 can be adjusted by changing the transmission ratio of the linkage rod 16 or the power input mode;

[0172] Step 6: Deep tillage and plowing: Start the traction device to drive the device forward; during the forward movement of the device, the deep tillage shovel 24 performs deep tillage and plowing operations on the soil;

[0173] Step 7, loosening operation: the first loosening wheel 9 and the second loosening wheel 10 further loosen the soil after deep loosening as the device moves forward, making the soil more fine-grained, creating good soil conditions for subsequent fertilization and corn planting; at the same time, the loosening rod 19 at the front end of the rear fertilizer discharge pipe 18 also assists in loosening the soil to ensure that the fertilizer can smoothly enter the soil;

[0174] Step 8, precise fertilization: the fertilizer in the corn fertilizer box 11 enters the corresponding fertilizer dispensing box 14 through the front fertilizer box discharge hopper 12 and the rear fertilizer box discharge hopper 13 respectively;

[0175] The feeding rotor 15 rotates under the drive of the linkage rod 16, and feeds the fertilizer into the front fertilizer discharge pipe 17 and the rear fertilizer discharge pipe 18. The fertilizer penetrates into the soil after deep tillage through the discharge pipes for fertilization.

[0176] Step 9. Finishing work: After the operation is completed, turn off the traction equipment and related power sources.

[0177] Clean the remaining fertilizer in the corn fertilizer box 11 to prevent the fertilizer residue from corroding the equipment, clean the soil adhering to the deep loosening shovel 24, the first loosening wheel 9, the second loosening wheel 10, and the loosening rod 19 components to keep the equipment clean.
