Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural irrigation and fertilization technology, and in particular to a mobile water and fertilizer integrated vehicle. Background Technology
[0002] Modern agriculture has an increasing demand for integrated water and fertilizer systems, but existing technologies exhibit a clear polarization. Fixed centralized irrigation systems rely on underground pipe networks and pump stations, resulting in high initial investment (100,000 yuan per 100 mu) and violating land resource protection policies due to their permanent land occupation exceeding 30 square meters. Conversely, while small push-type fertilizer applicators are highly mobile, their limited 200L capacity and manual operation make them unsuitable for large-scale production and large-scale operations. Furthermore, the static fertilizer tank design leads to severe fertilizer solution stratification, with EC values fluctuating by 167% beyond the industry standard of ±0.3.
[0003] To address the above issues, existing technology CN119999423A provides a drip irrigation device integrating water and fertilizer, but it suffers from the following systemic defects: the rigid concrete base completely renders the equipment immobile, requiring infrastructure damage for relocation; the continuous operation of the 2.2kW centrifugal pump results in a high daily energy consumption of 17.6kWh; and the secondary filtration system requires shutdown and disassembly for maintenance, with a single cleaning taking up to 120 minutes. These problems directly lead to increased operating costs and significantly reduce its applicability in complex terrains such as hilly areas.
[0004] Therefore, it is necessary to provide a new technical solution to solve the above-mentioned technical problems. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0028] Please see Figure 1This utility model provides a mobile fertigation vehicle, including an adjustable ground clearance walking mechanism, a fertigation tank 2, a mixing mechanism 3, and a fertilizer application pipe 7. The adjustable ground clearance walking mechanism includes a chassis 1 and a ground clearance adjustment mechanism (not shown). The ground clearance adjustment mechanism is mounted on the chassis 1 and is used to adjust the vertical distance between the chassis 1 and the ground, enabling the fertigation vehicle to be used in fields with all terrains (flat and uneven ground). The fertigation tank 2 is mounted on the adjustable ground clearance walking mechanism and is used to hold fertilizer solution. The mixing mechanism 3 is located on top of the fertigation tank 2 and includes a mixing pump and a mixing impeller extending into the fertigation tank 2. The mixing impeller is used to mix the fertilizer solution in the fertigation tank 2. The fertilizer application pipe 7 is mounted on the adjustable ground clearance walking mechanism. One end of the fertilizer application pipe 7 is connected to the outlet of the fertigation tank 2, and the other end of the fertilizer application pipe 7 is connected to the field pipeline network.
[0029] The ground clearance adjustment mechanism can be a hydraulic lifting mechanism, a pneumatic lifting mechanism, or an electromagnetic lifting mechanism.
[0030] The adjustable ground clearance walking mechanism can be remotely controlled. It measures 1.8m × 1.2m, has a load capacity of 700kg, and allows for adjustment of the ground clearance (vertical distance between the chassis and the ground) from 20cm to 40cm to adapt to ridge and furrow terrain. For example, the adjustable ground clearance walking mechanism can be adjusted to 20cm, 25cm, 30cm, or 40cm.
[0031] The chassis 1 uses a metal frame (tensile strength ≥290MPa) and is controlled by four brushless motors. Chassis 1 also has four tires, all herringbone-patterned, providing a 45° climbing ability. Chassis 1 is also equipped with dual reducers to prevent slippage.
[0032] The water and fertilizer tank 2 is made of PE material with a wall thickness of 5mm and a volume range of 500L-800L.
[0033] The mixing pump is sealed to the top of the water-fertilizer tank 2 via a flange. It has a power of 0.09kW and a speed of 600rpm, making it a low-power mixing pump. The low-speed mixing pump, together with the fan-shaped mixing impeller, forms an anti-sedimentation fertilizer solution circulation system, ensuring that the fertilizer solution in the water-fertilizer tank 2 circulates at a velocity ≥0.5m / s.
[0034] In one embodiment, the fertilizer pipe 7 is provided with a quick-connect interface at one end for connecting to the field pipe network, and the field pipe network is provided with a quick-connect fitting adapted to the quick-connect interface. The fertilizer pipe 7 is connected to the quick-connect fitting of the field pipe network through the quick-connect interface.
[0035] The quick-connect interface is equipped with a sealing structure to prevent it from detaching from the quick-connect connector.
[0036] The mobile fertigation vehicle of this invention also includes a proportional fertilizer pump 4, which is located near the outlet of the fertilizer pipeline 7, and is used to adjust the concentration of the fertilizer solution in the fertilizer tank 2. The proportional fertilizer pump 4 is a diaphragm type and adjusts the fertilizer solution at a ratio of 0.2%-2%.
[0037] Furthermore, the mobile water and fertilizer integrated vehicle of this utility model also includes a dual-stage filter 5, which is connected to the fertilizer pipeline 7 by a clamp and is located between the proportional fertilizer pump 4 and the quick-connect interface, and is used to filter the fertilizer solution in the water and fertilizer tank 2.
[0038] The dual-stage filter 5 has a filtration accuracy of 0.125 mm and a pressure resistance of 0.8 MPa. The dual-stage filter 5 includes a pre-filter and a post-filter. The pre-filter has a filtration aperture of 20 mesh, and the post-filter has a filtration aperture of 120 mesh.
[0039] like Figure 2 As shown, the mobile water and fertilizer integrated vehicle of this embodiment also includes a protective shell 8, which is set on an adjustable ground clearance walking mechanism and is used to cover the mixing mechanism 3, the fertilizer pipeline 7, the proportional fertilizer pump 4, the dual-stage filter 5, and at least part of the water and fertilizer tank 2.
[0040] Furthermore, the mobile water and fertilizer integrated vehicle also includes a lighting lamp 6, which is mounted on the protective shell 8.
[0041] like Figure 1 and Figure 2 As shown, the workflow for field operations using the mobile fertigation vehicle of this embodiment is as follows:
[0042] Phase 1: Equipment Deployment
[0043] The remote-controlled adjustable ground clearance walking mechanism allows the vehicle to traverse field ridges; the specific ground clearance can be adjusted according to the actual terrain. If used in poorly lit environments, a lighting lamp 6 can be deployed for illumination.
[0044] Phase 2: Fertilizer Solution Preparation
[0045] Start the stirring mechanism 3 and run it for 3-5 minutes to test the uniformity of the fertilizer solution (EC value fluctuation < ±0.2 mS / cm) to keep the uniformity of the fertilizer solution within the preset range.
[0046] Phase 3: Water and Fertilizer Operations
[0047] The proportional fertilizer pump 4 draws liquid from the water and fertilizer tank 2 at a set flow rate (e.g., 80L / min). The fertilizer solution is purified by a two-stage filter 5, and the purified fertilizer solution is connected to the field water supply valve through the fertilizer pipeline 7 (time ≤ 5 seconds).
[0048] Phase 4: Transfer Operations
[0049] After the fertilization operation is completed, disconnect the quick-connect joint between the fertilization pipeline 7 and the field pipeline network, and move the mobile water and fertilizer vehicle to the next plot of land.
[0050] The inventors conducted an experimental comparison between the mobile water and fertilizer integrated vehicle of this invention and the existing water and fertilizer integrated ground irrigation system. The comparison results are shown in the table below:
[0051] Quantitative Benefit Comparison Table
[0052]
[0053] As can be seen from the above, the mobile water and fertilizer integrated vehicle of this utility model does not require fixed land, has high transfer efficiency, is easy to move, has high fertilizer mixing uniformity, and significantly reduces system failure rate and energy consumption.
[0054] In addition, the mobile water and fertilizer integrated vehicle of this utility model has the following advantages: greatly improved agricultural economics, a single vehicle can cover 100 mu (replacing 1 fixed system), saving 100,000 yuan in equipment investment; reduced labor costs, reducing the number of operators from 3 to 1; precise fertilization reduces fertilizer loss (utilization increased by 25%), avoids the risk of underground pipeline leakage (an average annual reduction of fertilizer solution leakage of 2.3 tons / thousand mu), which is beneficial to ecological and environmental protection; it can also be compatible with more than 90% of field pipelines by replacing the quick-connect interface (Φ20 / 25 / 32mm); the lighting system supports night operation (extending effective working hours by 3-5 hours / day).
[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model 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 of the technical features.
