Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, and in particular to a foliar fertilizer granular solution spraying device for use with drones. Background Technology

[0002] In the booming development of modern agriculture, drones, with their high efficiency, convenience, and precision, have become an important tool for agricultural plant protection and fertilization operations. In agricultural production, the application of foliar fertilizers is a key means of supplementing crop nutrition and improving crop yield and quality. Traditional manual foliar fertilizer application methods are not only labor-intensive and time-consuming, but also extremely inefficient. Furthermore, it is difficult to achieve uniform application in large areas of farmland or complex terrain, resulting in inconsistent fertilization effects. With the rapid advancement of technology, drone technology has been introduced into foliar fertilizer spraying operations, enabling large-area and complex terrain spraying through drones equipped with spraying devices.

[0003] When foliar fertilizer granules are mixed with water in the spray tank, on the one hand, due to the difference in particle size, smaller particles may coat larger particles after absorbing water and dissolving, forming clumps with "dissolved outer shell and undissolved core". On the other hand, foliar fertilizers containing ingredients such as urea and humic acid are prone to absorbing moisture and clumping. If they are not broken up before mixing, they are prone to forming large clumps. These clumps and large clumps can cause blockages in pipes and nozzles during spraying. Even if filtered through the filter screen in the spray tank, the filter screen will also become clogged as particles accumulate, thus reducing spraying efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing foliar fertilizer granular solution spraying devices for drones are clogged by clumps and large particles in the solution, thus affecting the spraying efficiency. Therefore, this invention proposes a foliar fertilizer granular solution spraying device for drones.

[0005] To achieve the above objectives, the present invention employs the following technology: a foliar fertilizer granular solution spraying device for drones, comprising a drone body, a medicine tank detachably mounted on its bottom, nozzles being installed on both sides of the medicine tank via mounting pipes, and the solution in the medicine tank being pumped to the nozzles, and a landing gear being installed on the drone body.

[0006] The interior of the medicine box is divided into a first chamber and a second chamber arranged vertically by a filter screen. The first chamber is equipped with a stirring mechanism for mixing the granular solution and crushing the material with the filter screen to improve the mixing efficiency. The nozzle on the mounting pipe can be adjusted for spraying angle by an adjustment mechanism set on the medicine box.

[0007] As a further description of the above technical solution: the stirring mechanism includes a motor mounted on the medicine tank, and a stirring blade located in the first chamber is mounted on its output end via a connecting shaft.

[0008] As a further description of the above technical solution: a crushing and cleaning component is provided at one end of the stirring blade;

[0009] The crushing and cleaning assembly includes a mounting plate that is detachably connected to the stirring blade via a connecting frame, and the mounting plate is provided with a brush that contacts the surface of the filter screen.

[0010] As a further description of the above technical solution: the filter screen is provided with protrusions on one side of its filter holes, which cooperate with the brush to bind and break up particles.

[0011] As a further description of the above technical solution: the mounting pipe is rotatably mounted on one side of the medicine box via a bearing seat, and a flexible hose is provided between the mounting pipe and the output port of the pump body.

[0012] As a further description of the above technical solution: the adjustment mechanism includes a mounting bracket disposed on the side of the medicine box, a rack slidably connected to the mounting bracket, and a gear meshing with the rack on the mounting tube.

[0013] As a further description of the above technical solution: the rack is provided with a positioning plate that penetrates the top of the mounting bracket, the surface of the positioning plate is treated with anti-slip texture, and the mounting bracket is provided with positioning bolts that cooperate with the positioning plate.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] 1. The stirring mechanism can quickly mix foliar fertilizer granules and water, accelerate the dissolution process, avoid insufficient dissolution caused by granule agglomeration, and ensure uniform nutrient concentration in the solution;

[0016] 2. The protrusions on the filter screen are linked with the cleaning brush of the stirring mechanism. When the cleaning brush rotates, it can clean the filter screen in real time to prevent fine particles and sticky substances from clogging the filter screen pores and ensure the smooth passage of the solution. It can also work with the protrusions to squeeze and break up the adhering foliar fertilizer particles, decomposing large particles into fine particles that meet the requirements of the nozzle orifice size, reducing the risk of nozzle clogging.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-8 The foliar fertilizer granular solution spraying device for drones provided in this embodiment includes a drone body 1, a medicine tank 2 detachably mounted on its bottom, nozzles 4 are provided on both sides of the medicine tank 2 through mounting pipes 3, and the solution in the medicine tank 2 is transported to the nozzles 4 through a pump body 5. A hose is provided between the mounting pipe 3 and the output port of the pump body 5. The drone body 1 is also provided with a landing gear 9.

[0029] In this invention, a medicine tank 2 can be detachably installed at the bottom of the drone body 1 to store foliar fertilizer containing granular solution. After the pump 5 inside the medicine tank 2 is started, the solution is drawn out from the medicine tank 2 and the solution is driven to flow by pressure. The installation pipe 3 is connected to the nozzle 4. After the solution reaches the nozzle 4 through the installation pipe 3, the nozzle 4 atomizes the solution and sprays it onto the leaves of the crops. The nozzles 4 are installed on both sides of the medicine tank 2, which can expand the spray coverage area and improve the operation efficiency. The landing gear 9 on the drone body 1 provides stable support for the drone to take off and land, ensuring that the drone maintains balance during takeoff and landing and avoiding spillage of the solution in the medicine tank 2 or damage to the device components due to shaking.

[0030] It should be noted that the pump body 5 on the medicine tank 2 is a diaphragm pump that can control the flow rate, such as the XP30 diaphragm pump. Its flow rate range can be adjusted by the speed and it is commonly used in agricultural spraying equipment.

[0031] Specifically, such as Figure 3 and Figure 4 As shown, the interior of the medicine box 2 is divided into a first chamber and a second chamber arranged vertically by a filter screen 6. The first chamber is equipped with a stirring mechanism 7 for stirring and mixing the granular solution and for crushing materials in conjunction with the filter screen 6 to improve the mixing efficiency. The stirring mechanism 7 includes a motor 71 mounted on the medicine box 2, and a stirring blade 73 located in the first chamber is mounted on its output end via a connecting shaft 72.

[0032] The filter screen 6 inside the medicine tank 2 divides the medicine tank 2 into upper and lower chambers. The first chamber is used for mixing and stirring the foliar fertilizer granules and water. When the foliar fertilizer granules and water are added to the medicine tank 2, the motor 71 is started. The output end of the motor 71 drives the connecting shaft 72 to rotate, which in turn causes the stirring blade 73 to rotate at high speed in the first chamber. The stirring blade 73 stirs the solution to form a strong vortex, which accelerates the dissolution and dispersion of the foliar fertilizer granules and improves the mixing efficiency. Part of the foliar fertilizer granules dissolve in the solution, and the other part passes through the filter screen 6 and enters the second chamber. The filter screen 6 can intercept large particles that are not completely broken, ensuring that the particle size of the particles in the solution entering the second chamber meets the requirements, which provides a guarantee for uniform spraying through the nozzle 4 and reduces the risk of nozzle 4 clogging.

[0033] Specifically, such as Figures 3-6 As shown, a crushing and cleaning component 74 is provided at one end of the stirring blade 73. The crushing and cleaning component 74 includes a mounting plate 741 that is detachably connected to the stirring blade 73 via a connecting frame 743. A brush 742 is provided on the mounting plate 741 that contacts the surface of the filter screen 6. A protrusion 61 is provided on the filter screen 6 at one side of its filter holes to cooperate with the brush 742 to crush the adhering particles.

[0034] The filter screen 6 adopts an arc-shaped design, and its axis coincides with the axis of the connecting shaft 72. When the stirring blade 73 rotates under the drive of the motor 71, it drives the crushing and cleaning component 74 to rotate synchronously. When the crushing and cleaning component 74 rotates, the brush 742 continuously brushes the surface of the filter screen 6 to remove leaf fertilizer particles or viscous solution adhering to the filter holes, prevent the filter holes from clogging, maintain the permeability of the filter screen 6, and ensure that the mixed solution can pass smoothly through the filter screen 6 into the second chamber.

[0035] The protrusion 61 on one side of the filter screen 6 forms a mechanical interaction with the brush 742. When the adhered foliar fertilizer particles (such as clumps or large particles) are brought to the surface of the filter screen 6 by the agitated water flow, the rotation of the brush 742 will squeeze the particles toward the protrusion 61. The protruding structure of the protrusion 61 and the flexible scraping force of the brush 742 are used to shear, squeeze and break the particles, thereby improving the dissolution efficiency. Some of the broken particles enter the second chamber through the filter screen 6, while the large particles that are not completely broken continue to remain in the first chamber to participate in the agitation, avoiding particle accumulation and ensuring that the concentration of the foliar fertilizer solution is uniform. At the same time, it reduces the risk of blockage of the subsequent pump body 5 and nozzle 4 due to large particles.

[0036] Specifically, such as Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the mounting pipe 3 is rotatably mounted on one side of the medicine tank 2 via the bearing seat 31. The nozzle 4 on the mounting pipe 3 can be adjusted in spray angle via the adjustment mechanism 8 on the medicine tank 2. The adjustment mechanism 8 includes a mounting bracket 81 on the side of the medicine tank 2. A rack 82 is slidably connected to the mounting bracket 81, and a gear 32 that meshes with the rack 82 is provided on the mounting pipe 3. A positioning plate 83 that penetrates the top of the mounting bracket 81 is provided on the rack 82. The surface of the positioning plate 83 is treated with anti-slip texture. A positioning bolt 84 that cooperates with the positioning plate 83 is provided on the mounting bracket 81.

[0037] The nozzle 4 on the mounting pipe 3 can be adjusted according to usage needs. For low-growing crops such as vegetables and strawberries, the nozzle 4 angle can be adjusted to a downward tilt (e.g., 45°~60°) to concentrate the spray on the crop leaves, preventing excessive spray from drifting to the ground and improving adhesion. For taller crops such as fruit trees and corn, the nozzle 4 tilt angle can be increased (e.g., 60°~90°) to spray the spray upward onto the upper leaves or canopy, ensuring even coverage of the entire plant. The specific adjustment method is: loosen the fixed... Loosen the positioning bolt 84 to release the fixing state between the positioning plate 83 and the mounting bracket 81. Manually push or pull the positioning plate 83 to drive the rack 82 to slide up and down along the slide of the mounting bracket 81. The rack 82 meshes with the gear 32 on the mounting tube 3, driving the gear 32 to rotate, which in turn drives the mounting tube 3 to rotate around the bearing seat 31, thereby realizing the adjustment of the pitch angle of the nozzle 4. After the angle is adjusted to the target position, tighten the positioning bolt 84 so that the positioning plate 83 is tightly abutted against the mounting bracket 81 through the anti-slip texture, locking the position of the rack 82.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
