Description

Technical Field

[0001] This utility model relates to the technical field of seedling planting equipment, specifically a soil fertilization device for seedling planting. Background Technology

[0002] When planting seedlings, fertilization is required during the growth of seedlings in the nursery. Since seedlings are relatively fragile as they grow from seeds, fertilizer should not be applied too close to the roots. If the fertilizer dissolves in water, the concentration of fertilizer components at the roots will be higher than that inside the root cells, causing the roots to die due to insufficient water absorption, which can lead to seedling burn. Therefore, to solve the problem of fertilization distance during seedling planting, fertilizer is usually applied manually by spreading a ring of fertilizer around the outer circumference of the seedling.

[0003] According to a public announcement of a deep soil fertilization device for seedling planting (Announcement No.: CN219395523U), the above application includes an outer cylinder and a core rod. The core rod is vertically inserted inside the outer cylinder. A conical cylindrical mounting cover is fixed to the bottom end of the outer cylinder. A conical cover cloth is provided below the mounting cover, and multiple sets of diagonal braces that support the cover cloth are arranged around the inner side of the mounting cover. A synchronization disc is fixed to the bottom end of the core rod. Multiple sets of connecting rods are hinged to the outside of the synchronization disc. The bottom end of the connecting rod is inclined outward and hinged to the middle of the diagonal brace.

[0004] However, in actual use, the above-mentioned fertilization device presses out a ring-shaped groove around the seedling and then spreads fertilizer in the groove. At this time, the fertilizer is still exposed to the external environment. Some organic fertilizer components or microbial fertilizers will be destroyed by ultraviolet rays in sunlight, reducing their activity and causing rapid loss of fertilizer efficiency. In view of this, we propose a soil fertilization device for seedling planting. Utility Model Content

[0005] The purpose of this invention is to provide a soil fertilization device for seedling planting to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a soil fertilization device for seedling planting, comprising a cylinder, wherein a fertilization component is provided at the bottom of the cylinder, and the fertilization component includes:

[0007] A ring-shaped shovel, which is fixedly connected to the bottom end face of the cylinder;

[0008] A vertical rod, with an annular portion fixedly connected to its bottom end face, and an outer cylinder fixedly connected to its side wall, the top end face of which has a slot.

[0009] A pressure bar, wherein an extended portion is fixedly connected to the bottom end face of the pressure bar, and a soil loosening cone is fixedly connected to the bottom end face of the extended portion.

[0010] Preferably, the diameter of the annular shovel is larger than the diameter of the cylinder, and the bottom of the annular shovel has a cutting edge.

[0011] Preferably, the vertical rod is disposed inside the cylinder, and the outer cylinder is fitted against the inner wall of the cylinder.

[0012] Preferably, the annular portion abuts against the annular blade, the outer cylinder abuts against the inner wall of the annular blade, a cavity is provided between the outer cylinder and the annular portion, and a cavity is provided between the outer cylinder and the vertical rod, the cavities being used to contain fertilizer.

[0013] Preferably, the pressure rod is sleeved with the inner wall of the vertical rod, and the unfolded part is fitted with the inner wall of the annular part.

[0014] Preferably, the number of soil loosening cones is set in several groups, and the several groups of soil loosening cones are equally spaced on the bottom end face of the unfolded part. The soil loosening cones are in contact with the inner wall of the annular part. By rotating the pressure rod and the soil loosening cones, the soil at the fertilization site is loosened, so that the soil covers the fertilizer.

[0015] Preferably, a hopper is fixedly connected to the top end face of the cylinder, and the hopper is provided with a large diameter end and a small diameter end, with the large diameter end located on the side away from the top end face of the cylinder.

[0016] Compared with the prior art, this utility model provides a soil fertilization device for seedling planting, which has the following beneficial effects:

[0017] 1. This soil fertilization device for seedling planting, through its set fertilization components, allows for ring-shaped fertilization that bypasses the main root and concentrates the fertilizer on the lateral root absorption zone, matching the fertilizer with the high absorption area, greatly improving fertilizer utilization. It achieves closed-loop delivery and targeted fertilization, preventing spillage, pollution, and waste. The entire process avoids fertilizer exposure, reducing nutrient loss and improving utilization. The rotating soil loosening cone loosens the soil, allowing the soft soil to automatically collapse or turn over to cover the fertilizer, reducing the risk of nitrogen volatilization, phosphorus and potassium fixation, or nutrient washout by rainwater. This significantly improves the duration and utilization rate of fertilizer effectiveness. At the same time, soil loosening itself is an important means of promoting root respiration and expansion. This localized soil loosening is concentrated in the fertilizer application area, helping the roots extend towards the fertilizer area and improving absorption efficiency. After the soil is loosened, its permeability and aeration are enhanced, helping to prevent water accumulation and root rot or soil compaction.

[0018] 2. The soil fertilization device for seedling planting has a feeding hopper, which makes it easy to manually pour fertilizer. Even if the fertilizer particles are large or the method is not precise, the fertilizer can be smoothly poured into the hopper, which improves the operation error tolerance and reduces the risk of spillage, waste or pollution.

[0024] like Figures 1-4 As shown, this utility model provides a technical solution: a soil fertilization device for seedling planting, including a cylinder 1, and a fertilization component 2 is provided at the bottom of the cylinder 1. The fertilization component 2 includes a ring shovel 201, a vertical rod 202, a ring part 203, an outer cylinder 204, a groove 205, a pressure rod 206, an unfolding part 207, and a soil loosening cone 208.

[0025] In one embodiment of this utility model, the annular shovel 201 is fixedly connected to the bottom end face of the cylinder 1. The diameter of the annular shovel 201 is larger than the diameter of the cylinder 1, and the bottom of the annular shovel 201 is provided with a cutting edge.

[0026] The vertical rod 202 is installed inside the cylinder 1. The bottom end face of the vertical rod 202 is fixedly connected to an annular part 203. The side wall of the vertical rod 202 is fixedly connected to an outer cylinder 204. The outer cylinder 204 fits against the inner wall of the cylinder 1. The top end face of the outer cylinder 204 is provided with a slot 205. The annular part 203 abuts against the annular shovel 201. The outer cylinder 204 abuts against the inner wall of the annular shovel 201. A cavity is provided between the outer cylinder 204 and the annular part 203. A cavity is provided between the outer cylinder 204 and the vertical rod 202. The cavity is used to contain fertilizer.

[0027] The pressure rod 206 is sleeved with the inner wall of the vertical rod 202. The bottom end face of the pressure rod 206 is fixedly connected to the expansion part 207. The expansion part 207 is in contact with the inner wall of the annular part 203. The bottom end face of the expansion part 207 is fixedly connected to the loosening cone 208. Several sets of loosening cones 208 are set at equal intervals on the bottom end face of the expansion part 207. The loosening cones 208 are in contact with the inner wall of the annular part 203. By rotating the pressure rod 206 and the loosening cones 208, the soil in the fertilization area is loosened, so that the soil covers the fertilizer.

[0028] The annular part 203 is placed around the seedling. Pressing down on the vertical rod 202, the annular part 203, and the outer cylinder 204 presses down on the annular shovel 201. The annular shovel 201 presses out annular grooves around the seedling. At this time, because there is no limiting force on the pressure rod 206, the loosening cone 208 has no pressure and cannot penetrate the soil. After the annular part 203 is inserted into the soil along with the annular shovel 201, the loosening cone 208 fits against the inner wall of the annular part 203. Fertilizer is poured into the top of the cylinder 1, and the fertilizer enters the cavity through the groove 205. After lifting the vertical rod 202, the annular part 203... 03 and the outer cylinder 204 move upwards, and the fertilizer falls into the annular groove on the soil through the gap between the annular part 203 and the annular shovel 201. Then the inner top surface of the outer cylinder 204 and the annular shovel 201 abuts against each other, further pulling the cylinder 1 and the annular shovel 201 out of the soil. Annular fertilization can bypass the main root and concentrate the fertilizer on the lateral root absorption zone, matching the fertilizer with the high absorption zone, greatly improving the fertilizer utilization rate, realizing closed-loop transportation and fixed-position fertilization, preventing external spillage pollution and waste, avoiding fertilizer exposure throughout the process, reducing nutrient loss and improving utilization rate.

[0029] Press down the pressure rod 206 to insert the soil loosening cone 208 into the soil. Then rotate the pressure rod 206. The soil loosening cone 208 loosens the soil at the fertilization site, allowing the soil to cover the fertilizer. By rotating the soil loosening cone 208, the loose soil automatically collapses or turns over to cover the fertilizer, reducing the risk of nitrogen fertilizer volatilization, phosphorus and potassium fixation, or nutrients being washed away by rainwater. This significantly improves the duration and utilization rate of fertilizer effectiveness. At the same time, loosening the soil itself is an important means of promoting root respiration and expansion. This localized loosening effect is concentrated in the fertilizer application area, which helps the roots extend to the fertilizer area and improves absorption efficiency. After the soil is loosened, its permeability and aeration are enhanced, which helps to prevent water accumulation and root rot or soil compaction.

[0030] In addition, a hopper 3 is fixedly connected to the top end face of the cylinder 1. The hopper 3 is provided with a large diameter end and a small diameter end. The large diameter end is located on the side away from the top end face of the cylinder 1. The large opening design at the top makes it easy to manually pour fertilizer in. Even if the fertilizer particles are large or the method is not precise, they can enter the hopper smoothly, improving the operation error tolerance rate and making it less likely to spill, waste or contamination problems.

[0031] In this invention, during use, the annular part 203 is fitted around the seedling. Pressing down on the vertical rod 202, the annular part 203, and the outer cylinder 204 press down on the annular shovel 201, creating an annular groove around the seedling. Fertilizer enters the cavity through the groove opening 205. After lifting the vertical rod 202, the annular part 203 and the outer cylinder 204 move upward, and the fertilizer falls into the annular groove on the soil through the gap between the annular part 203 and the annular shovel 201. Then, the inner top of the outer cylinder 204 and the annular shovel 201... With the surfaces touching, the cylinder 1 and the ring shovel 201 are pulled out of the soil. Circular fertilization can bypass the main root and improve fertilizer utilization. Press down the pressure rod 206 and insert the soil loosening cone 208 into the soil. Then rotate the pressure rod 206 and the soil loosening cone 208 loosens the soil at the fertilization site, so that the soil covers the fertilizer. By rotating the soil loosening cone 208 to loosen the soil, the soft soil will automatically collapse or turn over to cover the fertilizer, reducing the risk of nitrogen fertilizer volatilization, phosphorus and potassium fixation, or nutrients being washed away by rainwater, and improving the duration and utilization rate of fertilizer effectiveness.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
