Description

Technical Field

[0001] This invention relates to the field of agricultural and forestry machinery technology, and more specifically, to a device and method for injecting liquid nutrients into fruit trees. Background Technology

[0002] Injecting pesticides, micronutrients, or plant growth regulators into fruit trees is a new technology that has been used in recent years to control pests and diseases, correct nutrient deficiencies, and regulate growth and development. Compared to spraying, where only about 20% of the pesticide is applied to the branches and leaves, while about 80% falls onto other objects or the ground, this method avoids waste and effectively prevents direct harm to natural enemies from certain pesticide components, while also ensuring the safety of the applicator. Its utilization rate for correcting nutrient deficiencies in fruit trees is four to five hundred times higher than soil fertilization and forty to fifty times higher than foliar spraying. Moreover, it is fast-acting, with effects lasting one to two years, and its effects on delaying leaf senescence, increasing fruit set rate, and improving fruit quality are very significant.

[0003] When injecting fruit trees, it is important to note that pesticides, micronutrients, or plant growth regulators should be a well-mixed solution. If the solution is not well mixed, the injected pesticide or nutrient content may be insufficient, making it difficult to achieve the desired effect, or the injected pesticide or nutrient content may be too high, causing the fruit trees to develop diseases or even die. Summary of the Invention

[0004] The technical problem to be solved by this invention is:

[0005] To address the problem that during fruit tree injection, the injected solution may not be mixed evenly, resulting in insufficient or excessive amounts of pesticides or nutrients, leading to poor cultivation results, diseases, or even death.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0007] This invention provides a device for injecting liquid nutrients into fruit trees, including a storage tank with a stirring device, the storage tank being mounted on a height-adjustable support, the storage tank having a vent and an injection port, the storage tank being connected to a main distribution pipe, the end of the main distribution pipe having a drain plug, the main distribution pipe being connected to at least one injection tube, the injection tube having a flow regulating valve, and the end of the injection tube having an injection needle.

[0008] Furthermore, the liquid storage tank includes a liquid storage tank body, and a rotary motor is provided at the upper end of the liquid storage tank body. The output end of the rotary motor is connected to a rotating shaft. The rotating shaft passes through the upper wall of the liquid storage tank body and extends into the interior of the liquid storage tank body. At least one set of stirring wheels is provided on the rotating shaft. The stirring wheel includes a stirring wheel fixing shaft and a plurality of stirring blades that are circumferentially arranged and evenly distributed on the outer wall of the stirring wheel fixing shaft. The stirring wheel fixing shaft is fixed on the rotating shaft.

[0009] Furthermore, when the number of stirring wheels is at least two, the stirring blades on each stirring wheel face the same direction, while the stirring blades of two adjacent stirring wheels face opposite directions.

[0010] Furthermore, the stirring blades are evenly distributed with several fins that are aligned along the extension direction of the stirring blades.

[0011] Furthermore, the distance between the bottommost stirring wheel and the bottom inner wall of the liquid storage tank body is 1cm-3cm.

[0012] Furthermore, the bracket includes a holder for placing the liquid storage tank. The holder is connected to the base via a telescopic rod at the center. At least three support rods are evenly arranged circumferentially on the outer wall of the telescopic sleeve of the telescopic rod. The support rods are rotatably connected to the outer wall of the telescopic sleeve. A fixing plate is rotatably connected to the end of the support rod. A threaded fixing plug is detachably provided on the fixing plate. The upper end of the fixing plug is a handle, and the lower end of the fixing plug is a pointed end.

[0013] Furthermore, one end of the support rod is rotatably connected via a support rod rotating fixing seat, and the support rod also includes a support rod rotating shaft, which sequentially passes through one end of the support rod rotating fixing seat, the support rod, and the other end of the fixed support rod rotating fixing seat.

[0014] Furthermore, the injection tube is provided with a protective hose, which may be an opaque pull tube.

[0015] A method for injecting liquid nutrients into a fruit tree injection device includes the following steps:

[0016] Step 1: Adjust the height of the support according to the height of the fruit tree. Inject pesticides or nutrients into the storage tank through the injection port. Open the vent and flow regulation valve. Test whether the solution can flow from the needle. After the test, close the flow regulation valve to prevent the solution from flowing out of the storage tank.

[0017] Step 2: Drill or punch holes at least 3 points on the tree trunk using a drill or nail. The hole diameter should match the needle tip, and the depth should be 5-7 cm. The holes should be at a 40°-50° angle to the tree trunk. Remove the drill or nail and remove all sawdust from the holes. Insert the special needle into the small holes and turn on the rotary motor for 10-15 minutes. Then open the flow regulating valve and wait until the liquid slowly flows into the tree trunk. Depending on the size of the tree, 50mL-200mL of liquid can be injected per tree. After injection, close the vent and remove the needle. Plug the hole with yellow mud to prevent liquid evaporation and infection inside the hole.

[0018] Furthermore, when using it again, the yellow mud inside the gadolinium can be removed or the cotton ball can be pulled out before reuse.

After stirring for a certain period using a rotating motor, the injection needle is inserted into the hole. After use, the vent is closed and the holes are plugged.

[0021] This invention discloses a device and method for injecting liquid nutrients into fruit trees. Before and during injection, the solution is thoroughly stirred to ensure the pesticides or nutrients are fully dissolved in the water. Continuous stirring during injection prevents pesticide or nutrient precipitation, ensuring the injected solution does not form a concentration gradient and effectively improving the injection effect. Furthermore, this device is reusable, has a simple structure, and is easy to operate. Attached Figure Description

[0031] Specific Implementation Plan Two: Combining Figures 1 to 4 As shown, the storage tank 1 includes a storage tank body 101. A rotary motor 102 is provided at the upper end of the storage tank body 101. The output end of the rotary motor 102 is connected to a rotating shaft 105. The rotating shaft 105 passes through the upper wall of the storage tank body 101 and extends into the interior of the storage tank body 101. At least one set of stirring wheels 106 are provided on the rotating shaft 105. The stirring wheel 106 includes a stirring wheel fixing shaft 107 and a plurality of stirring blades evenly distributed circumferentially on the outer wall of the stirring wheel fixing shaft 107. The stirring wheel fixing shaft 107 is fixed on the rotating shaft 105. It is used to drive the rotating shaft 105 to rotate by the rotary motor 102, thereby causing the stirring wheels 106 to rotate, and stirring the solution in the storage tank 1.

[0032] The other combinations and connections in this implementation scheme are the same as in Specific Implementation Scheme 1.

[0033] Preferably, when there are at least two stirring wheels 106, the stirring blades on each stirring wheel 106 face the same direction, and the stirring blades of two adjacent stirring wheels 106 face opposite directions, so that when two adjacent stirring wheels 106 rotate during stirring, the solution will collide, thereby enhancing the stirring effect.

[0034] Preferably, the stirring blades are evenly distributed with a plurality of fins that are aligned along the direction of the stirring blades, in order to further improve the stirring effect.

[0035] Preferably, the distance between the stirring wheel 106 at the bottom and the bottom inner wall of the liquid storage tank body 101 is 1cm-3cm, so that when stirring, the pesticides or nutrients deposited at the bottom of the liquid storage tank body 101 can float up with the water flow and be fully dissolved in the solution.

[0036] Preferably, the support includes a bracket 4 for placing the liquid storage tank 1. The bracket 4 is connected to the base 8 via a telescopic rod 7 at the center. At least three support rods are evenly arranged circumferentially on the outer wall of the telescopic sleeve of the telescopic rod 7. The support rod 5 is rotatably connected to the outer wall of the telescopic sleeve. A fixing plate 9 is rotatably connected to the end of the support rod 5. A fixing plug 10 is detachably provided on the fixing plate 9 by threaded connection. The upper end of the fixing plug 10 is a handle, and the lower end of the fixing plug 10 is a pointed part. It is used to fix the telescopic rod 7 after adjusting the height according to the height of the fruit tree, adjust the rotation angle of each support rod 5, rotate the fixing plate 9 to be horizontal with the ground, and rotate the handle to rotate the fixing plug 10 into the ground to complete the fixing of the liquid storage tank 1.

[0037] Preferably, one end of the support rod 5 is rotatably connected via the support rod rotating fixing seat 6, and the support rod also includes a support rod rotating shaft, which sequentially passes through one end of the support rod rotating fixing seat 6, the support rod 5, and the other end of the fixed support rod rotating fixing seat 6.

[0038] Preferably, the injection tube is provided with a protective hose 11, which can be an opaque tube that can be used to protect the injection tube, especially suitable for pesticides or nutrients that need to be used in the dark.

[0039] Preferably, the injection needle 12 includes a needle tip 13 and a needle tip connector, and one end of the injection tubing can be snapped onto the needle tip connector to prevent the protective tubing 11 from slipping off during injection.

[0040] Specific Implementation Plan Three: Combining Figures 1 to 4 As shown, the present invention provides an injection method for a fruit tree nutrient injection device, comprising the following steps:

[0041] Step 1: Adjust the height of the support according to the height of the fruit tree. Inject pesticides or nutrients into the storage tank 1 through the injection port 103. Open the vent 104 and the flow regulating valve. Test whether liquid can be dispensed from the needle 13. After the test, close the flow regulating valve to prevent the solution from flowing out of the storage tank 1.

[0042] Step 2: Using a drill or nail, drill or punch at least 3 holes on the tree trunk (10cm above the rootstock). The hole diameter should match the needle 13, and the hole depth should be 5-7cm. The hole should be at a 40°-50° angle to the tree trunk. Remove the drill or nail and remove all sawdust from the hole. Insert the special needle 13 into the small hole, turn on the rotary motor 102 and rotate it for 10-15 minutes. Then open the flow regulating valve and wait until the liquid slowly flows into the tree trunk. Depending on the size of the tree, 50-200mL of liquid can be injected into each tree. After injection, close the vent 104 and remove the needle 13. Plug the hole with yellow mud to prevent liquid evaporation and infection inside the hole.

[0043] When you need to "inject" it again, you can remove the yellow mud inside the gadolinium or pull out the cotton ball to make a new hole for reuse.

[0044] The other combinations and connections in this implementation scheme are the same as those in specific implementation scheme one or two.

[0045] Preferably, the solution in the storage tank can be a nutrient element rich in selenium, strontium, zinc or chromium that is needed by the human body, and is added to the storage tank at a volume ratio of 1:80 with water.

[0046] Selenium is an essential trace element for the human body, with particularly significant effects on the digestive, respiratory, cardiovascular, and nervous systems. It enhances and improves digestion and absorption, promotes normal gastrointestinal motility, prevents constipation, and alleviates bloating, abdominal pain, nausea, aversion to oily foods, and loss of appetite. It protects the function of cardiovascular endothelial cells and cell epithelium, aiding in the repair of vascular endothelial cells in cardiovascular diseases such as coronary atherosclerotic heart disease, insufficient cerebral blood supply, and cerebral vascular stenosis. It increases the antiviral and immune functions of the respiratory system, reducing the incidence of upper respiratory tract infections and acute pneumonia. It also improves sleep, enhances sleep quality, and promotes deep sleep.

[0047] Zinc plays a vital role in promoting growth and development, enhancing intelligence, maintaining normal appetite, and promoting wound healing. It participates in protein synthesis, cell growth, division, and differentiation, and is also involved in the metabolism of luteinizing hormone, follicle-stimulating hormone, and gonadotropins, playing a crucial regulatory role in fetal growth and development, as well as the development of sexual organs and functions. Zinc helps maintain normal taste and smell because gustin, a zinc-containing protein, promotes the differentiation of taste buds and the binding of flavorful substances to them. Furthermore, it promotes wound healing: when skin tissue is damaged, zinc, copper, and other minerals in the blood and tissues redistribute, leading to a decrease in blood zinc levels. Supplementing with zinc-containing preparations can, to some extent, promote wound healing.

[0048] Strontium can improve sleep quality. Excessive fatigue from work or smoking during the day can cause platelet aggregation and vasoconstriction, affecting the body's ability to relax and fall asleep. Sufficient intake of the trace element strontium can inhibit this, thus effectively improving sleep quality. It can also promote hemoglobin synthesis, thus having a good effect on replenishing qi and blood; inhibit the formation of lipid peroxides in the skin, slowing down aging and thus having a good beauty and skin-nourishing effect; effectively enhance the body's immunity; effectively reduce the occurrence of depression and make the mind clearer; and delay the rise in blood pressure, reduce blood pressure fluctuations, slow plaque formation in the process of atherosclerosis, reduce liver cell damage, and significantly lower blood uric acid levels.

[0049] Chromium is an important trace element with many important functions in the human body: it can promote the action of insulin, thereby improving the uptake and utilization of glucose by cells and helping to control blood sugar levels; it can lower plasma triglyceride and cholesterol levels while raising high-density lipoprotein cholesterol levels, which helps prevent cardiovascular disease; it can enhance the body's immunity, increase the number and activity of white blood cells, and help prevent infection and tumors; and it can promote the growth and development of children and the cell repair and regeneration of adults.

[0050] Preferably, the fruit tree may be an apple, orange, kiwi, pear, walnut, grape, or mangosteen.

[0051] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
