Detailed Implementation

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] Reference Figure 1-3 This utility model provides a tillage and harrowing topdressing device, comprising:

[0041] Main frame 1, with mounting bracket 2 installed on the front side of main frame 1, and main frame 1 connected to agricultural machinery through mounting bracket 2;

[0042] The shallow fertilization mechanism includes a first fertilizer box 3 fixedly connected to the top of the main frame 1, a first fertilizer component installed at the bottom front side of the main frame 1, and the first fertilizer component and the first fertilizer box 3 are connected by a delivery pipe I 4.

[0043] The deep fertilization mechanism includes a second fertilizer box 5, which is fixedly connected to the top rear side of the main frame 1. A deep tillage component, a second fertilization component, and a soil covering component are sequentially arranged at the bottom of the main frame 1 along the forward direction. The second fertilization component and the second fertilizer box 5 are connected by a conveying pipe II 6.

[0044] Follower component, the follower component is installed on the main frame 1;

[0045] A quantitative dispensing component is installed on the first fertilizer box 3 and the second fertilizer box 5 respectively; the first fertilizer component and the second fertilizer component are arranged in a staggered manner.

[0046] Depth-limiting wheel 7 is located in the middle of the main frame 1;

[0047] Among them, a seedling protector 8 is set between the deep tillage component and the first fertilization component.

[0048] In operation, the device is connected to agricultural machinery (such as a tractor) via the mounting frame 2, with the machinery providing the forward propulsion and power source. The main frame 1 serves as the core structure of the entire device, supporting various components such as the shallow fertilization mechanism, deep fertilization mechanism, follow-up assembly, quantitative discharge assembly, and depth-limiting wheel 7. The fertilizer in the first fertilizer box 3 is controlled by the quantitative discharge assembly to ensure uniform and accurate fertilization. The fertilizer is transported to the first fertilization assembly via the conveying pipe I 4. As the agricultural machinery moves forward, the first fertilization assembly applies fertilizer to the surface or shallow soil layer to meet the crop's nutrient requirements. While the agricultural machinery moves forward, the deep tillage assembly first performs deep tillage, breaking up soil compaction and improving soil structure. A seedling protector 8 is positioned between the deep tillage assembly and the first fertilization assembly to protect crop seedlings and prevent damage during deep tillage and fertilization. The fertilizer in the second fertilizer box 5 is controlled by the quantitative discharge assembly and then transported to the second fertilization assembly via the conveying pipe II 6. The second fertilization component applies fertilizer to the deeply tilled soil, achieving deep fertilization and meeting the crop's need for deep nutrients. The soil covering component then covers the fertilizer with soil, ensuring thorough mixing and improving fertilizer utilization. The servo component allows the device to flexibly adjust its position according to the movement of the agricultural machinery, adapting to different terrains and operational needs. The depth-limiting wheel 7, located in the middle of the main frame 1, controls the operating depth of the device, ensuring the accuracy of fertilization and deep tillage.

[0049] Further optimization of the scheme: the first fertilization component includes a notched disc harrow 9 and a shallow tillage disc 10. A telescopic rod 11 is fixedly connected to the bottom of the main frame 1. A connecting shaft is rotatably connected to the center of the notched disc and the shallow tillage disc 10. The connecting shaft is rotatably connected to the bottom of the telescopic rod 11. An angle is set between the axis of the shallow tillage disc 10 and the axis of the notched disc harrow 9. A fertilizer pipe I is fixedly connected to the rear side of the bottom end of the telescopic rod 11. One end of the delivery pipe I4 is inserted into the fertilizer pipe I.

[0050] As the agricultural machinery moves forward, the notched disc harrow 9 and the shallow tillage disc 10 begin to rotate. The notched disc harrow 9, through its notched design, effectively shreds and turns the soil, creating a loose soil environment for fertilization. The shallow tillage disc 10, with its specific angle and rotation, further refines the soil and gently agitates the topsoil, contributing to the even distribution of fertilizer. Fertilizer is transported from the first fertilizer box 3 through the delivery pipe I4 to the vicinity of the first fertilizer assembly. Due to the turning action of the disc harrow and disc, the fertilizer is evenly mixed into the soil. The telescopic rod 11 allows adjustment of the tillage depth of the disc harrow and disc according to soil hardness and crop root depth, ensuring optimal fertilization and tillage results.

[0051] Further optimization of the scheme: the deep tillage component includes a deep tillage disc 12, and a support arm 13 is fixedly connected to the bottom of the main frame 1. The support arm 13 has an L-shaped structure, and the deep tillage disc 12 is rotatably connected to the end of the support arm 13.

[0052] The scheme is further optimized. The second fertilization component includes fertilization pipe II, which is fixedly connected between the follow-up component and the deep tillage disc 12. The bottom end of the delivery pipe II 6 is inserted into the fertilization pipe II.

[0053] Further optimization of the scheme: the soil covering component includes two sets of soil covering wheels 14. The rear end of the main frame 1 is detachably connected to a fixed arm 15 via a connector. The two sets of soil covering wheels 14 are respectively rotatably connected to the bottom end of the fixed arm 15.

[0054] The scheme is further optimized. The follower component includes a follower wheel. A connecting rod is vertically fixed to the bottom of the main frame 1, and the follower wheel is rotatably connected to the bottom of the connecting rod.

[0055] The scheme is further optimized. The quantitative discharge component includes a distribution gear. Several sets of distribution gears are set. Several discharge ports are opened at the bottom of the first fertilizer box 3 and the bottom of the second fertilizer box 5. The bottom of the first fertilizer box 3 and the bottom of the second fertilizer box 5 are rotatably connected to the connecting shaft. The connecting shaft passes through the discharge port. Several distribution gears are rotatably connected to the connecting shaft, and the distribution gears are set one-to-one with the discharge port.

[0056] Material receiving funnels are fixedly connected to the top ends of conveying pipe I4 and conveying pipe II6, respectively, and the material receiving funnels are correspondingly arranged with the material distributing gears. Discharge motors are installed on the side walls of the first fertilizer box 3 and the second fertilizer box 5, respectively, and the discharge motors are used to drive the connecting shaft to rotate.

[0057] To further optimize the design, lids 16 are installed on the first fertilizer box 3 and the second fertilizer box 5 respectively.

[0058] The deep tillage assembly consists of a deep tillage disc 12 and an L-shaped support arm 13. The deep tillage disc 12 is rotatably connected to the end of the support arm 13. When the agricultural machinery moves forward, the deep tillage disc 12 rotates and penetrates into the soil to perform deep tillage operations.

[0059] The Deep Tillage Disc 12 is designed to effectively break up soil compaction, improve soil structure, and provide deeper growing space for crop roots.

[0060] The second fertilization component includes a fertilizer pipe II, which is fixedly connected between the follower component and the deep tillage disc 12. The bottom end of the conveying pipe II 6 is inserted into the fertilizer pipe II, so that fertilizer can be directly conveyed into the fertilizer pipe II through the conveying pipe II 6.

[0061] While the deep tillage disc 12 is deeply tilling, fertilizer is evenly spread onto the tilled soil through fertilizer pipe II, achieving simultaneous deep tillage and fertilization.

[0062] The soil covering assembly consists of two sets of soil covering wheels 14 and a fixed arm 15. The fixed arm 15 is detachably connected to the rear end of the main frame 1 via a connector, and the soil covering wheels 14 are rotatably connected to the bottom end of the fixed arm 15.

[0063] After deep plowing and fertilization, the covering wheel 14 rotates and covers the fertilizer with soil, ensuring that the fertilizer is fully mixed with the soil and improving fertilizer utilization.

[0064] The follower assembly includes a follower wheel and a connecting rod. The follower wheel is rotatably connected to the bottom of the connecting rod, and the connecting rod is vertically fixed to the bottom of the main frame 1.

[0065] The design of the follower wheel allows the device to flexibly adjust its position according to the movement of the agricultural machinery, adapting to different terrains and operational needs, and ensuring the smooth progress of deep plowing, fertilization and soil covering operations.

[0066] The quantitative discharge assembly consists of a distributing gear and a receiving funnel. The bottom of the first fertilizer box 3 and the second fertilizer box 5 are respectively provided with several discharge ports. The connecting shaft passes through the discharge ports, and the distributing gear is rotatably connected to the connecting shaft and is set one by one with the discharge ports.

[0067] As the distributing gears rotate, they control the amount of fertilizer discharged, ensuring the uniformity and accuracy of fertilization. A receiving funnel is positioned corresponding to the distributing gears; fertilizer falls from the distributing gears into the receiving funnel and is then transported to the fertilization assembly via a conveying pipe.

[0068] The simultaneous implementation of deep tillage, fertilization, and soil covering greatly improves operational efficiency and reduces the time spent on repetitive tillage and fertilization.

[0069] The design of the quantitative discharge component ensures uniform fertilizer discharge. Combined with the deep tillage operation of the deep tillage disc 12 and the uniform application of fertilizer pipe II, the fertilizer can be more evenly distributed in the soil.

[0070] The design of the Deep Tillage Disc 12 can effectively break up soil compaction, improve soil structure, enhance soil aeration and water retention, and benefit crop growth.

[0071] The design of the follow-up components enables the device to adapt to different terrains and operational requirements, improving the device's versatility and adaptability.

[0072] The design of the covering wheel 14 ensures that the fertilizer is fully covered by the soil, increasing the contact area between the fertilizer and the soil, thereby improving the utilization rate of the fertilizer.
