Description

Technical Field

[0001] This utility model relates to the field of agricultural fertilization equipment technology, and in particular to a simple quantitative fertilization device. Background Technology

[0002] Agricultural fertilization is a key aspect of improving crop yield and quality. Proper fertilization provides crops with essential nutrients, promoting healthy growth. However, both excessive and insufficient fertilization can negatively impact crop growth and even lead to soil pollution and environmental problems. Therefore, precise and quantitative fertilization has become an important direction for modern agricultural development.

[0003] Traditional fertilization methods mainly rely on manual operation, which has the following problems:

[0004] Uneven fertilization: Manual fertilization makes it difficult to ensure the uniform distribution of fertilizer, resulting in inconsistent crop growth;

[0005] Fertilizer application is difficult to control: the lack of precise measuring devices makes it easy to over- or under-fertilize.

[0006] High labor intensity: Manual fertilization is inefficient and labor-intensive, especially in large areas of farmland;

[0007] Environmental pollution risk: Excessive fertilization can lead to fertilizer loss and pollution of soil and water sources.

[0008] Currently, some fertilization equipment is available on the market. For example, patent document CN 218680056 U discloses a simple quantitative fertilization device for flue-cured tobacco, including: a fertilizer bucket with a water inlet on the top and a detachable cover; a water-pressing structure located at the bottom of the fertilizer bucket; and a water delivery rod, one end of which is connected to the water outlet of the water-pressing structure via a hose, and the other end of which is fixedly connected to a metering cup. This device has a simple structure and can control the amount of fertilizer applied to a certain extent, making it very popular among small-scale farmers. However, when using this device, the fertilizer bucket needs to be carried manually, which is labor-intensive, and during the fertilization process, liquid fertilizer continuously flows into the metering cup, affecting the accuracy of fertilization. Meanwhile, some large-scale intelligent fertilization equipment on the market is expensive, complex to operate, and has high maintenance costs, making it unsuitable for ordinary farmers and difficult to popularize among small-scale farmers.

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0032] Example 1

[0033] like Figure 1 As shown, a simple quantitative fertilization device includes a fertilizer storage tank 1 and a top cover 2 on top of the storage tank 1. The storage tank 1 is equipped with a stirring mechanism 3. The top cover 2 has a feed inlet 201, and the bottom of the storage tank 1 has a discharge outlet 101. The discharge outlet 101 is connected to a liquid outlet rod 5 via a pumping pipe system 4. The discharge outlet of the liquid outlet rod 5 is connected to a quantitative fertilization container 6. A control valve 7 is also provided on the liquid outlet rod 5. In use, water and fertilizer are added to the storage tank 1 in a specific ratio to create water-soluble fertilizer. The water-soluble fertilizer is then transported to the liquid outlet rod 5 via the pumping pipe system 4. The operator controls the opening and closing of the control valve 7 to quantitatively dispense the water-soluble fertilizer into the quantitative fertilization container 6, thus achieving quantitative fertilization.

[0034] The fertilizer storage tank 1 is equipped with a handrail 102 on one side of the upper part and rollers 103 on the bottom surface, which makes it easy to move and saves time and effort in operation.

[0035] In this embodiment, the stirring mechanism 3 can be designed with reference to the principle of a waterwheel. Specifically, the stirring mechanism 3 includes a rotating shaft 301 located below the feed inlet 201 and connected to the inner wall of the fertilizer storage tank 1, with a plurality of blades 302 evenly distributed circumferentially on the rotating shaft 301. When water is added to the fertilizer storage tank 1, the water flow impacts the blades 302, and the resulting force drives the blades 302 to rotate, thereby achieving the stirring function.

[0036] Below the feed inlet 201, there is a downwardly inclined guide plate 303. The rotating shaft 301 of the stirring mechanism is located on one side of the guide plate 303, and the blades 302 are close to the inclined surface of the guide plate 303. When water is added to the fertilizer storage tank, the water flows downward along the guide plate 303, which makes it easier for the water to impact the blades 302 and make them rotate.

[0037] A filter screen structure 304 is also provided below the mixing mechanism 3. The filter screen 304 can better mix fertilizer and water in the mixing zone and prevent large fertilizer particles from falling to the bottom of the fertilizer storage tank 1, which would result in insufficient mixing.

[0038] The pumping pipeline system 4 includes a water supply pump 401 located at the outlet 101 of the fertilizer storage tank and a water supply hose 402 connected to the water supply pump 401. A wall-mounted automatic hose reel 403 is installed on the side of the fertilizer storage tank 1 near the outlet 101, and the water supply hose 402 is wound up onto the wall-mounted automatic hose reel 403. The wall-mounted automatic hose reel 403 can be any commercially available hose reel, and can be a manual hose reel or an electric hose reel. The length of the water supply hose 402 can be set according to the fertilization area to ensure that fertilization can be completed in the entire fertilization area, making operation time-saving and efficient. After use, it can be wound up onto the wall-mounted automatic hose reel 403, saving space and making storage and management convenient.

[0039] The upper end of the liquid outlet rod 5 is provided with a handle 501, and the control valve 7 is a push-button water valve set on the handle, which is more convenient to operate.

[0040] The quantitative fertilizer container 6 is a transparent plastic cup 601 with graduations, and a flow guide spout is provided on the top edge of the cup, which makes the fertilization operation more convenient.

[0041] Example 2

[0042] like Figure 2 As shown, based on Embodiment 1, the stirring mechanism 3 is an electric stirrer. The electric stirrer includes a stirring paddle 305 installed inside the fertilizer storage tank 1, and the stirring paddle 305 is connected to a stirring motor 306 installed on the top cover 2. In use, water and fertilizer are added to the fertilizer storage tank 1 in proportion, and stirred by the electric stirrer to produce water-soluble fertilizer, making the operation more convenient.

[0043] Example 3

[0044] like Figures 3-5 As shown, based on Examples 1 and 2, the quantitative fertilizer container 6 is a graduated conical fertilizer applicator 602. The discharge port at the bottom of the conical fertilizer applicator is connected to a sealing plug 603 via an elastic pressing structure. In use, press the press-type water valve on the handle 501 to discharge the water-soluble fertilizer into the conical fertilizer applicator 602. When the water-soluble fertilizer reaches the required scale, close the water valve, press the elastic pressing structure to open the sealing plug 603, and discharge the water-soluble fertilizer into the area to be fertilized, thus completing one quantitative fertilization.

[0045] A base plate 604 with a drainage hole is provided at the discharge port at the bottom of the conical fertilizer applicator 602. The elastic pressing structure includes a connecting shaft 605 mounted on the base plate. The bottom end of the connecting shaft 605 extends out of the conical fertilizer applicator 602 and is connected to a pressing block 606 with a drainage hole. The top end of the connecting shaft 605 extends into the conical fertilizer applicator 602 and is connected to a sealing plug 603. A spring 607 is fitted on the connecting shaft 605. In use, the liquid dispensing rod 5 is held and pressed down on the pressing block 606 in the area to be fertilized, causing the connecting shaft 605 to move upward and push open the sealing plug 603 to achieve fertilization. Afterward, the liquid dispensing rod 5 is lifted, and under the action of the spring 607, the connecting shaft 605 moves downward, causing the sealing plug 603 to return to its original position and block the discharge port at the bottom of the conical fertilizer applicator 602.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
