Technical Field

[0001] This utility model relates to the field of fertilization device technology, specifically to a front-and-back grouped layered fertilization component. Background Technology

[0002] The core purpose of agricultural fertilization is to provide comprehensive and balanced nutrients for crop growth, maintain soil fertility, and achieve sustainable agricultural production. The fertilization process typically involves: first, determining the type and amount of fertilizer based on soil fertility and crop needs, and then mixing organic and chemical fertilizers evenly in a specific ratio; next, breaking up the plow pan to loosen the soil; and finally, thoroughly mixing the fertilizer with the soil through methods such as broadcasting or hole application, ensuring the fertilizer is evenly distributed within the 0-20 cm tillage layer, creating favorable nutrient conditions for crop sowing and seedling growth.

[0003] The shortcomings of existing technologies are that they use single-layer soil fertilization methods such as broadcasting and hole application, which can easily lead to an imbalance in nutrient ratios, fail to establish a system for supplying fertilizer, and cannot accurately supply nutrients, resulting in low fertilizer utilization. Utility Model Content

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this technical solution clearer, the following detailed description, in conjunction with specific embodiments, further illustrates this technical solution. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this technical solution.

[0017] Please see Figure 1-8 This utility model provides a technical solution: a front-to-back grouped layered fertilization assembly, including a support frame 1, two first fertilization components 2, and two second fertilization components 3. The two first fertilization components 2 are located at the front end of the support frame 1, and the two second fertilization components 3 are located at the rear end of the support frame 1 (front-to-back direction as shown). Figure 1 (As shown). The first fertilization component 2 includes a first connector 21 and a first soil breaking component 22. The second fertilization component 3 includes a second connector 31 and a second soil breaking component 32. The first soil breaking component 22 has a first fertilizer discharge channel 222 inside, and the second soil breaking component 32 has a second fertilizer discharge channel 322 inside.

[0018] Please see Figure 1-3 and Figure 7-8In use, this invention utilizes a traction device (such as a tractor) to move the support frame 1 forward. The support frame 1 then moves the two first fertilization components 2 and two second fertilization components 3 forward. The first soil-breaking component 22 and the second soil-breaking component 32 break the soil, creating trenches on the land surface. During this process, fertilizer is fed into the first fertilizer discharge channel 222 and the second fertilizer discharge channel 322, falling into the trenches created on the land surface. In this invention, the bottom of the second soil-breaking component 32 is higher than the bottom of the first soil-breaking component 22, and the distance between the two second soil-breaking components 32 is greater than the distance between the two first soil-breaking components 22. Therefore, there is a gap between the trenches created by the first soil-breaking component 22 and the second soil-breaking component 32, and the trenches created by the first soil-breaking component 22 are deeper, while the trenches created by the second soil-breaking component 32 are shallower. This allows the fertilizer discharged through the first fertilizer discharge channel 222 to penetrate deeper soil layers, and the fertilizer discharged through the second fertilizer discharge channel 322 to penetrate both shallow and deep soil layers.

[0019] This invention establishes a comprehensive fertilization system that precisely supplies nutrients and improves fertilizer utilization. The combination of deep and shallow fertilization improves soil structure, prevents excessive nutrient concentration in the surface layer leading to compaction, promotes root development, and enhances crop resistance to lodging and drought. Furthermore, stratified fertilization extends the fertilizer's effectiveness, meeting the nutrient needs of crops throughout their entire growth cycle, resulting in increased yield and improved quality. It also reduces fertilizer usage, lowers agricultural non-point source pollution, and balances economic and ecological benefits.

[0020] Example 1

[0021] Please see Figure 1-8 The first connecting member 21 includes two first soil-breaking discs 221, and the second connecting member 31 includes two second soil-breaking discs 321. The two first soil-breaking discs 221 and the two second soil-breaking discs 321 together form a V-shaped structure, thus enabling both the first and second soil-breaking discs 221 to quickly break through the soil. A first fertilizer discharge channel 222 is formed between the two first soil-breaking discs 221, and a second fertilizer discharge channel 322 is formed between the two second soil-breaking discs 321. Both the first and second connecting members 21 are equipped with fertilizer delivery pipes, which correspond to the positions of the first and second fertilizer discharge channels 222 and 322, respectively. A fertilizer storage box can be installed on the top of the support frame 1. After connecting the two fertilizer delivery pipes to the inside of the fertilizer storage box, during the movement of the support frame 1, the fertilizer in the fertilizer storage box can enter the first and second fertilizer discharge channels 222 and 322 respectively through the two fertilizer delivery pipes.

[0022] Please see Figure 4-8The second soil-breaking disc 321 has several evenly distributed arc-shaped notches 323 at its edge, which makes the fertilizer entering the shallow trench more even. The first soil-breaking disc 221 is detachably connected to the first connecting member 21, and the second soil-breaking disc 321 is detachably connected to the second connecting member 31. When the first soil-breaking disc 221 or the second soil-breaking disc 321 is damaged, it can be removed and replaced, which gives this invention the advantage of convenient maintenance.

[0023] Example 2

[0024] Please see Figure 4-8 Both the first fertilizer discharge channel 222 and the second fertilizer discharge channel 322 are equipped with anti-blocking components 4. Since both the first connector 21 and the second connector 31 have a V-shaped structure, both the first fertilizer discharge channel 222 and the second fertilizer discharge channel 322 are narrow at the front and wide at the rear. When fertilizer enters the first fertilizer discharge channel 222 or the second fertilizer discharge channel 322, if it moves to the inner front of the first connector 21 or the second connector 31, it can easily cause fertilizer accumulation and blockage. The anti-blocking components 4 can block the fertilizer during its descent, allowing it to fall through the wider rear section of the first fertilizer discharge channel 222 or the second fertilizer discharge channel 322, effectively preventing fertilizer accumulation and blockage. Please see Figure 4-8 Within the first fertilizer discharge channel 222, the anti-blocking component 4 is fixedly connected to the first connecting member 21. Within the second fertilizer discharge channel 322, the anti-blocking component 4 is fixedly connected to the second connecting member 31. The anti-blocking component 4 includes an arc-shaped first baffle 41 and a second baffle 42, with the fertilizer discharged through the fertilizer delivery pipe positioned precisely between the first baffle 41 and the second baffle 42. The concave surfaces of the first baffle 41 and the second baffle 42 face each other. The fertilizer discharged through the fertilizer delivery pipe first impacts the concave surface of the first baffle 41, then bounces along the concave surface of the first baffle 41 onto the concave surface of the second baffle 42, and finally slides down along the concave surface of the second baffle 42 into the trench. The positions of the first baffle 41 and the second baffle 42 are carefully designed. The first baffle 41 is guaranteed to catch the fertilizer discharged from the fertilizer delivery pipe, and the second baffle 42 ensures that the fertilizer can pass through either the first fertilizer discharge channel 222 or the second fertilizer discharge channel 322, and that the fertilizer falls into the trench instead of splashing outside the trench.

[0025] Example 3

[0026] Please see Figure 1-5 and Figure 7The tops of both the first connecting member 21 and the second connecting member 31 can slide along the outer surface of the support frame 1. A first locking member 5 is provided between the tops of both the first connecting member 21 and the second connecting member 31 and the support frame 1. In this embodiment, the first locking member 5 is a fastening screw, and the support frame 1 has several threaded holes that mate with the fastening screw. After loosening the fastening screw, moving the two first connecting members 21 or the two second connecting members 31 horizontally can adjust the distance between the first breaking member 22 or the two second breaking members 32, thereby adjusting the distance between the deep trench and the shallow trench. After adjustment, tightening the fastening screw will fix the tops of both the first connecting member 21 and the second connecting member 31 to the support frame 1.

[0027] Please see Figure 1-5 and Figure 7 A second locking element 6 is provided between the two first connecting parts 21 and between the two second connecting parts 31. Since the bottoms of the first connecting parts 21 and the second connecting parts 31 are far from the first locking element 5, relative displacement can easily occur at the bottoms of the two first connecting parts 21 or the two second connecting parts 31 during the process of the first breaking part 22 and the second breaking part 32 breaking through the soil. In this invention, the two second locking elements 6 can respectively connect the bottoms of the two first connecting parts 21 and the bottoms of the two second connecting parts 31 together, ensuring that the bottoms of the first connecting parts 21 and the second connecting parts 31 do not experience relative displacement, and that the trenches created by the first breaking part 22 and the second breaking part 32 breaking through the soil always remain straight.

[0028] Please see Figure 1-5 and Figure 7 In this embodiment, the second locking member 6 includes a screw and four locking nuts. The first connecting member 21 and the second connecting member 31 are respectively sleeved on the two screws. The locking nuts can clamp the first connecting member 21 or the second connecting member 31 from both sides. When it is necessary to change the distance between the first breaking member 22 or the two second breaking members 32, the locking nuts are loosened, so that the distance between two adjacent locking nuts increases, and the first connecting member 21 and the second connecting member 31 can move and change their position in the horizontal direction. After the position is adjusted, the locking nuts are tightened again to fix the bottom of the first connecting member 21 and the second connecting member 31.

[0029] The above content is only a preferred embodiment of this utility model. For those skilled in the art, many changes can be made in the specific implementation and application scope based on the ideas of this technical content. As long as these changes do not depart from the concept of this utility model, they all fall within the protection scope of this patent.
