Description

Technical Field

[0001] This utility model belongs to the field of agricultural fertilization equipment technology, specifically relating to a foliar sprayer for automatically dispensing water-soluble fertilizer. Background Technology

[0002] Water-soluble fertilizer (WSF) is a compound fertilizer that dissolves completely in water. It contains a variety of nutrients required for plant growth, such as nitrogen (N), phosphorus (P), potassium (K), and trace elements (iron, zinc, copper, manganese, etc.). After dissolving, the nutrients exist in ionic form, which can be directly absorbed by plant roots or leaves, with a utilization rate of over 90%. The fertilizer formula, concentration, and application method can be flexibly adjusted according to the crop's growth stage and needs, achieving precise fertilization. Furthermore, water-soluble fertilizer leaves no residue, is friendly to soil and the environment, and reduces fertilizer loss and pollution.

[0003] Foliar spraying of soluble fertilizers is a common fertilization method in crop cultivation. To determine the optimal concentration of water-soluble fertilizer for crop growth, it is usually necessary to prepare water-soluble fertilizer solutions of different concentrations and conduct spraying experiments on different groups of crops. Furthermore, the amount of foliar fertilizer required for leaf spraying is relatively small, necessitating a smaller spray container. However, fruit tree foliar fertilizer application typically uses traditional backpack-style manual pressurized sprayers. Traditional liquid fertilizer spraying devices (such as pesticide sprayers carried on the back) only have a single container to hold the diluted fertilizer. Therefore, during spraying, the operator needs to frequently return to the workbench to repeatedly open, clean, fill, dilute, and re-cover the container, resulting in cumbersome operation, low efficiency, uneven spraying, and impacting experimental progress and fertilization effectiveness. Therefore, developing a foliar fertilizer sprayer with wide applicability, high fertilization efficiency, and easy application is of significant practical importance. Utility Model Content

[0004] The purpose of this invention is to provide an automatic liquid fertilizer mixing and spraying device to solve the problem that traditional spraying devices repeatedly dilute the fertilizer during foliar spraying, making it impossible to efficiently mix and dilute the foliar fertilizer. This improves fertilization efficiency, simplifies the operation process, and solves the problem of uneven spraying of multiple crops.

[0005] The technical solution of this utility model is as follows: an automatic foliar sprayer for dispensing water-soluble fertilizer, comprising a sprayer body, the sprayer body including a spray box, a spraying mechanism, a power supply compartment and a concentrate adjustment mechanism; a water storage tank is provided at the top of the spray box, and a spraying chamber is provided below the water storage tank, with three stirring blades inside the spraying chamber; a concentrate adjustment mechanism is provided on the side of the spray box, and a liquid storage tank is provided inside the concentrate adjustment mechanism, which is connected to the spraying chamber; a power supply compartment is provided at the bottom of the spraying chamber, and a battery, a paddle-type stirrer motor and a water pump are provided inside the power supply compartment, with the water pump connected to both a waste liquid tank and the spraying mechanism through a distributor.

[0006] The above-mentioned foliar sprayer for automatically dispensing water-soluble fertilizer has a water inlet on the spray box, a cover above the water inlet, and the water inlet is connected to a water storage tank.

[0007] In the above-mentioned foliar sprayer for automatically dispensing water-soluble fertilizer, the upper part of the concentrate adjustment mechanism is a liquid storage tank, and the bottom of the liquid storage tank is connected to the spraying tank through a liquid flow sensor.

[0008] The above-mentioned foliar sprayer for automatically dispensing water-soluble fertilizer has a liquid inlet at the top of the liquid storage tank, and a cover is fitted over the liquid inlet.

[0009] The above-mentioned foliar sprayer for automatically dispensing water-soluble fertilizer has a control module on the spray box, which is equipped with a sensor display screen and control buttons.

[0010] In the above-mentioned foliar sprayer for automatically dispensing water-soluble fertilizer, the diverter is connected to the waste liquid tank and the spraying mechanism via a waste liquid hose and a spraying hose, respectively.

[0012] The aforementioned foliar sprayer for automatically dispensing water-soluble fertilizer has a flow sensor at the spray switch.

[0013] The aforementioned foliar sprayer for automatically dispensing water-soluble fertilizer has a nozzle equipped with an atomizing spray outlet.

[0014] The aforementioned foliar sprayer for automatically dispensing water-soluble fertilizer in greenhouses has an adjustment knob at the atomizing spray nozzle.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] 1. This sprayer is equipped with a water storage tank, a liquid storage tank, and a spraying tank. Water and concentrate can be pre-filled into different tanks before fertilization. During application, simply open the flow sensor of the corresponding chamber through the control mechanism to prepare the water-soluble fertilizer of the corresponding concentration. This solves the problem of spraying liquid fertilizer dilutions of different concentrations as needed. There is no need to return to the operating table to refill the water-soluble fertilizer of another concentration after each application of one concentration of water-soluble fertilizer. This can effectively simplify the fertilization operation and improve the fertilization efficiency.

[0017] 2. This sprayer is also equipped with a waste liquid tank, which allows the flow of liquid from the spray chamber to the waste liquid hose or the spray hose to be controlled by adjusting the distributor. After the spray chamber is rinsed with water in the storage tank, the waste liquid outlet is opened to store the waste liquid in the waste liquid tank; when spraying, simply open the spray outlet to spray normally. This ensures the accuracy of the spray concentration and reduces the repetitive operation of returning to the operating state for cleaning.

[0018] 3. A flow sensor is installed at the spraying mechanism of this sprayer to display the spraying volume and solve the problem of uneven spraying. Attached Figure Description

[0023] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0024] Example 1

[0025] To address the problems of traditional liquid fertilizer spraying devices (such as pesticide sprayers carried on the back) having single containers and requiring small amounts of foliar fertilizer, thus necessitating multiple trips back to the operating table for cleaning and leaf replacement during spraying operations, resulting in cumbersome processes and low spraying efficiency, this embodiment provides an automatic foliar sprayer for dispensing water-soluble fertilizer, including a spraying box 1, a spraying mechanism 2, and a concentrate adjustment mechanism 4.

[0026] The spraying box 1 has a wall thickness of approximately 0.5 cm and a water inlet 11 with a diameter of approximately 5 cm at the top, along with a cover 111. Inside the box, from top to bottom, are arranged a water storage tank 15, a spraying tank 16, and a power mechanism compartment 3, each with upper and lower inlet / outlet ports. A flow sensor is installed between the water storage tank 15 and the spraying tank 16. A concentrate regulating mechanism 4 is located on the upper side of the spraying box 1. The concentrate regulating mechanism 4 contains a storage tank 14, which is connected to the spraying tank 16 via a silicone hose. A flow sensor is installed on the silicone hose, transmitting data to the control module 13 at the top of the spraying box 1 via a circuit. The control module 13 has control buttons 131 and a sensor display screen 132. The power mechanism compartment 3 includes a battery 31, a paddle agitator 32, and a water pump 33. Before spraying, clean water and concentrated foliar fertilizer are stored in water storage tank 15 and liquid storage tank 14. The amount of water and concentrated liquid entering can be adjusted by control module 13, and then the paddles are used to stir and mix them to realize the automatic preparation of foliar fertilizer.

[0027] The paddle mixer 32 includes a paddle mixer motor 321 and a mixing blade 322. The paddle mixer motor 321 is located inside the power mechanism chamber 3, and the mixing blade 322 is located inside the spraying chamber 16.

[0028] The spraying chamber 16 is connected to a water pump 33 via a hose. The outlet of the water pump 33 is equipped with an on / off diverter 331, which also connects to the waste liquid tank 17 located on the lower right side of the housing and the spraying mechanism 2. The water pump 33 is connected to the spraying mechanism 2 and the waste liquid tank 17 via a spraying hose 333 and a waste liquid hose 332, respectively. The waste liquid tank 18 is located below the storage tank 14. An adjusting diverter 331 is installed between the water pump 33, the spraying hose 333, and the waste liquid hose 332. By adjusting the diverter 331, the liquid in the spraying chamber 16 can be either discharged into the waste liquid tank 18 or fed into the spraying mechanism 2. By controlling the water intake of the storage tank 15, stirring, and then discharging into the waste liquid tank 18, the spraying chamber 16 can be cleaned, allowing for the next round of foliar fertilizer preparation. This reduces the need for manual cleaning at the operating table and minimizes errors caused by an uncleaned spraying chamber 16.

[0029] The spray box 1 can be equipped with a carrying strap, allowing the sprayer to be used for field spraying operations. Alternatively, casters can be installed at the bottom, enabling the sprayer to be dragged across relatively flat ground, reducing labor costs. The spraying mechanism 2 is connected in sequence as follows: inlet hose 21, spray switch 22, spray gun 23, and nozzle 24. The nozzle 24 is equipped with several atomizing spray nozzles 241, each with an adjustment knob. These nozzles atomize the water-soluble fertilizer in the spray chamber, spraying it onto the leaves.

[0030] Correspondingly, if the power consumption of pump 33 is too high, a manual pressurization mode can be used. An air pump and air hose are connected to the spray chamber, with the manual air pump fixedly located on the left side of the chamber. A pressure gauge can be installed in the chamber to display the pressure value. Air pumping must be stopped when the pressure displayed on the gauge reaches the specified pressure.

[0031] The method of using this utility model is as follows: The water storage tank 15 is filled with water, and the liquid storage tank 14 of the concentrate regulating mechanism 4 is filled with the liquid fertilizer or water-soluble fertilizer solution to be sprayed. According to the required concentration, the amount of water and liquid fertilizer added to the spraying tank 16 is controlled by the control button 131 of the control module 13. The paddle agitator 32 mixes the liquid fertilizer and water in the spraying tank 16 evenly. The distributor 331 is adjusted to discharge the liquid in the spraying tank 16 into the spraying mechanism 2. The spraying switch 22 is turned on to spray the crops on the leaves. After the diluted liquid fertilizer solution in the spraying tank 16 has been sprayed, liquid fertilizer and water can be added again following the above steps, mixed, and then sprayed. Alternatively, the spraying tank 16 can be cleaned by adding water from the water storage tank 15 into the spraying tank 16, turning on the paddle agitator 32 to clean the spraying tank 16, and adjusting the distributor 331 to discharge the liquid in the spraying tank 16 into the waste liquid tank 17, thus completing the cleaning operation.
