Description

Technical fields:

[0001] This utility model relates to a quantitative foliar fertilization device. Background technology:

[0002] When fertilizing vegetables, tobacco, and other plants, a long-handled scoop is usually used to scoop liquid fertilizer (such as liquid fertilizer or farmyard manure) from a fertilizer bucket in order to reduce fertilizer waste. However, this method requires the fertilizer bucket containing the liquid fertilizer to be next to the fertilizer applicator, who then needs to walk along the soil ridges around the plants, thus requiring the fertilizer bucket to be moved from time to time, resulting in low fertilization efficiency. Summary of the Invention:

[0003] In view of the problems existing in the prior art, the purpose of this utility model is to propose a quantitative foliar fertilization device, which is reasonably designed and conducive to improving fertilization efficiency.

[0004] This utility model is implemented using the following solution.

[0005] The present invention relates to a quantitative foliar fertilization device, characterized in that: it includes a handheld tube and a metering cylinder fixedly connected to the first end of the handheld tube in the middle; the second end of the handheld tube is connected to a metal spray pipe extending into the body of the handheld tube; the outlet end of the metal spray pipe extends into the metering cylinder; the inlet end of the metal spray pipe is fixed to the second end of the handheld tube and a manual valve is fixedly installed on the inlet end of the metal spray pipe; the end of the manual valve is connected to a water and fertilizer integrated machine through a flexible hose.

[0006] Preferably, a sealing element is provided between the outer peripheral wall of the liquid outlet end of the metal spray tube and the inner wall of the second end of the handheld tube to prevent the liquid fertilizer output to the metering cylinder from flowing into the handheld tube.

[0007] Preferably, the metering cylinder is positioned perpendicular to the handheld tube.

[0008] Preferably, the metering cylinder is cylindrical with an inclined surface at its opening.

[0009] Preferably, the metering cylinder is cylindrical, and a rotatable inner tube is fitted on the inner circumferential wall of the metering cylinder. An elastic sealing ring is fitted between the outer circumferential wall of the inner end of the rotatable inner tube and the inner circumferential wall of the metering cylinder to secure the position of the rotatable inner tube relative to the metering cylinder. The outer end of the rotatable inner tube is a bevel.

[0010] The working principle of this utility model's quantitative foliar fertilization device is as follows: the end of the manual valve is connected to a water-fertilizer integrated machine via a hose. The water-fertilizer integrated machine is equipped with an infusion pump. After the fertilizer applicator opens the manual valve, the fertilizer solution can be sprayed from the outlet end of the metal spray pipe into the quantitative cylinder. After the quantitative cylinder is filled once, it can be tilted towards the soil around the plant's roots, allowing the fertilizer solution in the quantitative cylinder to flow into the soil around the plant's roots, completing the fertilization of one plant. Then, while moving to the next plant, the fertilizer applicator opens and closes the manual valve as described above to inject liquid into the quantitative cylinder. When reaching the next plant, the fertilizer solution in the quantitative cylinder is poured out. This process is repeated to complete the fertilization work.

[0011] This utility model of a quantitative foliar fertilization device eliminates the need to repeatedly move the fertilizer bucket and repeatedly scoop fertilizer solution from the bucket, thus greatly facilitating the fertilization process and improving fertilization efficiency.

[0017] Figure 6 yes Figure 5 A partial view. Detailed implementation method:

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] This utility model of a quantitative foliar fertilizer application device includes a handheld tube 1 and a metering cylinder 2 that is fixedly connected to the first end of the handheld tube through the middle. The metering cylinder and the handheld tube can be set vertically or non-vertically. That is, a through hole is opened on the cylinder wall of the metering cylinder 2 for inserting the first end of the handheld tube. The first end of the handheld tube can be glued and fixed in the through hole. Both the handheld tube 1 and the metering cylinder 2 can be made of plastic material. The length of the handheld tube can be 0.5-1.2 meters and the diameter can be 2-3 centimeters. The volume of the metering cylinder 2 is 30-200 milliliters.

[0020] The second end of the handheld tube is connected to a metal spray pipe 3 that extends into the body of the handheld tube. The outlet end of the metal spray pipe 3 extends into the metering cylinder 2, so that the water-fertilizer solution sprayed from the metal spray pipe can enter the metering cylinder. The inlet end of the metal spray pipe is fixed to the second end of the handheld tube, and a manual valve 4 is fixedly installed on the inlet end of the metal spray pipe. That is, the outer circumference of the inlet end of the metal spray pipe has an external thread that is threaded to the second end of the handheld tube, and the inner hole of the inlet end of the metal spray pipe has an internal thread that is threaded to the outer circumference of the manual valve 4. The end of the manual valve is connected to the water-fertilizer integrated machine 6 through a hose 5. The water-fertilizer integrated machine 6 has an infusion pump 10.

[0021] When using the fertilizer, the operator opens the manual valve, and the fertilizer solution is sprayed from the outlet of the metal spray pipe into the metering cylinder. After the metering cylinder is filled (the supply volume is controlled by the opening time of the manual valve), the operator tilts the metering cylinder towards the soil around the plant's roots, allowing the fertilizer solution to flow into the soil around the plant's roots, thus completing the fertilization of one plant. Then, while moving to the next plant, the operator opens and closes the manual valve as described above to inject the solution into the metering cylinder. When reaching the next plant, the operator pours out the fertilizer solution from the metering cylinder. This process is repeated to complete the fertilization.

[0022] To ensure accurate metering, a sealing element 7 is provided between the outer peripheral wall of the liquid outlet end of the aforementioned metal spray tube and the inner wall of the second end of the handheld tube. This sealing element can prevent the liquid fertilizer output to the metering cylinder from flowing into the handheld tube. The sealing element 7 can be a sealing ring or a sealing sleeve covering the entire circumference.

[0023] To facilitate the pouring of the liquid fertilizer, one embodiment is that the measuring cylinder is cylindrical with an inclined opening, which makes pouring the liquid fertilizer easier and more convenient.

[0024] In another embodiment, the metering cylinder is cylindrical, with a rotatable inner tube 8 fitted onto its inner circumferential wall. An elastic sealing ring 9 is fitted between the outer circumferential wall of the inner end of the rotatable inner tube and the inner circumferential wall of the metering cylinder to secure the position of the rotatable inner tube relative to the metering cylinder. The outer end of the rotatable inner tube is beveled. Since different users have different gripping habits and postures, the beveled surface on the outer end of the rotatable inner tube 8 allows different fertilizer applicators to adjust the relative position of the rotatable inner tube 8 relative to the metering cylinder arbitrarily. The elastic sealing ring 9 secures the position of the rotatable inner tube relative to the metering cylinder and can be replaced after a period of use. Of course, the elastic sealing ring 9 can also be omitted, ensuring an interference fit between the outer circumferential wall of the rotatable inner tube 8 and the inner circumferential wall of the metering cylinder. Under a large external force, the rotatable inner tube 8 can rotate relative to the metering cylinder.

[0025] In this application, "quantitative" does not refer to a strictly quantitative amount of fertilizer, but rather to the amount of fertilizer applied in relation to spraying.

[0026] This utility model of a quantitative foliar fertilization device eliminates the need to repeatedly move the fertilizer bucket and repeatedly scoop fertilizer solution from the bucket, thus greatly facilitating the fertilization process and improving fertilization efficiency.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
