Description

Technical Field

[0001] This utility model relates to the field of fertilization equipment technology, and in particular to a foliar fertilizer spraying device for laboratory use. Background Technology

[0002] In laboratories, foliar fertilization of plants is a common experimental procedure, primarily used to study plant growth, development, and nutrient absorption. Traditional foliar fertilization methods often involve manual hand-held sprayers, which have several drawbacks. First, manual spraying is inefficient, time-consuming, and labor-intensive for spraying a significant number of plants. Second, manual spraying struggles to ensure uniformity and consistency, leading to uneven fertilization across different plant parts and affecting the accuracy of experimental results. Furthermore, hand-held spraying involves close contact with the nozzle, potentially posing health risks to operators. Additionally, traditional methods lack flexibility, making precise adjustments based on plant height and distribution difficult. Therefore, developing a laboratory foliar fertilization spraying device that improves spraying efficiency, ensures uniformity, and ensures safe operation is of great significance.

[0046] Combined with appendix Figures 1-3 A laboratory foliar fertilizer spraying device includes a vehicle body 1, an electric pump 2, an atomizing device 3, a storage tank 4, and a support frame 5. The electric pump 2 is bolted to the frame 1-1 of the vehicle body 1. The storage tank 4 is located on top of the electric pump 2 and is connected to the inlet of the electric pump 2 via a pipe. The storage tank 4 is preferably made of transparent material to facilitate the operator's observation of the liquid level, and its capacity is designed to meet the needs of large-area spraying in a single operation. The operator can fill the pre-prepared foliar fertilizer solution into the tank 4 through the injection port on top of the tank 4. As the vehicle body 1 moves, the solution in the storage tank 4 can be continuously supplied to the electric pump 2, ensuring the continuity of the spraying process. The storage tank 4 is also equipped with a sealing cap to prevent leakage or evaporation of the solution during movement. By moving the vehicle body 1, the operator can easily spray the foliar fertilizer in the storage tank 4 onto the target plants. Electric pump 2 provides stable power output, ensuring that the foliar fertilizer solution is sprayed out in a uniform mist, thus achieving efficient spraying results. Its powerful motor can meet the needs of long-term, large-area spraying while guaranteeing the uniformity and stability of the spray.

[0047] A support frame 5 is installed on at least one side of the vehicle body 1, its main function being to provide stable support for the atomizing device 3. The atomizing device 3 is installed on the top of the support frame 5, allowing the atomizing device 3 to spray synchronously as the vehicle body 1 moves. Depending on actual needs, operators can install the support frame 5 on one or both sides of the vehicle body 1. (See attached...) Figure 2 As shown, when support frames 5 are set on both sides, atomizing devices 3 can be installed on the top of each support frame 5, thereby achieving simultaneous spraying of plants on both sides of the vehicle body 1, significantly improving work efficiency and effectively saving time and manpower.

[0048] As attached Figure 3 As shown, the atomizing device 3 includes an extension tube 3-1, a connecting hose 3-2, a bend 3-3, and a Y-shaped atomizing nozzle. One end of the extension tube 3-1 is detachably connected to the support frame 5, and the other end is connected to the Y-shaped atomizing nozzle via the bend 3-3. The extension tube 3-1 is also connected to the outlet of the electric pump 2 via the connecting hose 3-2, so that the foliar fertilizer pumped by the electric pump 2 is introduced into the Y-shaped atomizing nozzle through the extension tube 3-1 and the bend 3-3. This detachable connection design allows the atomizing device 3 to be securely installed on the vehicle body 1 for mobile spraying operations, and can also be easily removed when needed. The operator can hold the atomizing device 3 for more precise and flexible spraying operations to meet the fertilization needs of different plants or specific areas.

[0049] This embodiment provides a preferred Y-shaped atomizing nozzle, comprising a main nozzle 3-4 and at least two auxiliary nozzles 3-6. The main nozzle 3-4 is connected to a curved pipe 3-3, and the auxiliary nozzles 3-6 are connected to the main nozzle 3-4 via connecting pipes 3-5, extending radially downwards. Both the main nozzle 3-4 and the auxiliary nozzles 3-6 are equipped with independent switches, allowing the operator to independently control the spraying of the main nozzle 3-4 and the auxiliary nozzles 3-6 according to actual needs, thereby flexibly adjusting the spraying range. This design can simultaneously cover the top and surrounding area of ​​the plant, greatly improving spraying efficiency. The nozzles of the main nozzle 3-4 and the auxiliary nozzles 3-6 can atomize the foliar fertilizer solution into tiny particles, ensuring that the solution can evenly adhere to the surface of the plant leaves, improving fertilizer absorption efficiency.

[0050] Furthermore, the connecting pipes 3-5 are flexible, possessing a degree of plasticity that allows them to bend and shape within a certain range. Operators can flexibly adjust the spraying angle of each auxiliary nozzle 3-6 according to actual needs, thereby better adapting to the shape and layout of different plants and improving spray uniformity and coverage. The flexible pipe design not only increases spraying flexibility but also reduces the problem of some areas being missed due to fixed-angle spraying. Example 2

[0051] Combined with appendix Figure 1 and 4 The laboratory foliar fertilizer spraying device of this invention is an improvement upon Example 1. To facilitate spraying for different plants, the support frame 5 in this embodiment is designed to include an adjustable telescopic rod 5-1, the bottom of which is fixedly connected to the frame 1-1 of the vehicle body 1. The telescopic rod 5-1 adopts a multi-segment telescopic design and is locked to the desired length by a knob or buckle. The operator can adjust the length of the telescopic rod 5-1 according to the height of the plant, thereby adjusting the height of the atomizing device 3 to accommodate plants of different heights. This design allows the device to flexibly handle plants of different heights.

[0052] The top of the telescopic rod 5-1 is equipped with a ring socket 5-2. The end of the extension tube 3-1 facing away from the Y-shaped atomizing nozzle is closed, and this closed end is inserted into the ring socket 5-2 to keep the extension tube 3-1 horizontally fixed. Alternatively, the end facing away from the Y-shaped atomizing nozzle is equipped with a connector rod 3-7, which engages with the ring socket 5-2 to keep the extension tube 3-1 horizontally fixed. The design of the connector rod 3-7 and the ring socket 5-2 allows for quick installation and disassembly of the atomizing device 3, facilitating adjustments by the operator according to actual needs. When plants are arranged in rows or columns, the operator can insert the connector rod 3-7 into the ring socket 5-2 to securely mount the atomizing device 3 onto the vehicle body 1. By pushing the vehicle body 1 along the direction of plant arrangement, the foliar fertilizer spraying operation can be completed quickly. If the plants are irregularly arranged, the operator can manually control the spraying range of the atomizing device 3 by holding the connector rod 3-7. This design allows the atomizing device 3 to be used flexibly in different scenarios, improving the adaptability and convenience of spraying operations.

[0053] In addition, to prevent the connecting hose 3-2 from affecting the continuity of the operator's spraying work, or from excessively rubbing against other parts of the vehicle body 1 and affecting its service life, an elastic buckle can be installed on one side of the support frame 5. The elastic buckle has an adjustable elastic opening that can be inserted into the connecting hose 3-2 and fixed in place. Example 3

[0054] Combined with appendix Figure 1 and 5 The laboratory foliar fertilizer spraying device of the present invention is further optimized based on Example 1 or 2. The vehicle body 1 includes an arched frame 1-1, which has good load-bearing capacity and stability. A handle 1-2 is provided at the top of the frame 1-1. The handle 1-2 is ergonomically designed and covered with anti-slip rubber to facilitate the operator in pushing the vehicle body 1. A switch for controlling the electric pump 2 is installed below the handle 1-2. The switch can be designed to be waterproof and dustproof, thus better protecting the switch and extending its service life.

[0055] Wheels 1-3 are mounted on both sides of the bottom of the frame 1-1, at the end where the handle 1-2 is located. The wheels 1-3 are positioned closer to the handle 1-2 at the bottom of the frame 1-1. The wheels 1-3 can be made of high-elasticity rubber to provide good shock absorption and wear resistance. The wheels 1-3 are connected to the frame 1-1 via bearings, allowing for flexible rotation and ensuring smooth movement of the vehicle body 1. A support leg 1-4 is mounted at the bottom of the frame 1-1, away from the wheels 1-3. The support leg 1-4 is adjustable and can be locked at the desired height using a knob or clip, maintaining stability of the vehicle body 1 on uneven ground. This design allows the operator to raise the support leg 1-4 for smooth movement during spraying operations, and to lower the support leg 1-4 to maintain stability when not moving, making it convenient to use.

[0056] In addition, vehicle body 1 is equipped with a mobile power supply (not shown in the figure), which can provide continuous and stable power support for electric pump 2. The addition of the mobile power supply enables vehicle body 1 to move over long distances, thus facilitating foliar fertilizer spraying operations over large areas and further improving its overall applicability and flexibility. Example 4

[0057] Combined with appendix Figure 1 The laboratory foliar fertilizer spraying device of the present invention is a further improvement on any of the embodiments in Examples 1 to 3. Two storage tanks 4 are provided on the top of the electric pump 2, and both storage tanks 4 are connected to the inlet of the electric pump 2 via a switching valve. This dual-tank design can significantly increase the filling volume of foliar fertilizer, thereby meeting the needs of large-area spraying. Alternatively, it can spray foliar fertilizers that cannot be dissolved in solvents simultaneously in two separate applications. When spraying in two separate applications, the designated storage tank 4 can be selected and connected to the electric pump by switching the switching valve.

[0058] The storage tank 4 and the electric pump 2 are connected and fixed in a detachable manner. This design makes it easy for the operator to remove the storage tank 4 for cleaning or refilling of foliar fertilizer solution, and also facilitates the operator's maintenance and upkeep of the electric pump 2.

[0059] Furthermore, for spraying different foliar fertilizers in two separate applications, the two storage tanks 4 can be filled with different types of foliar fertilizers, better meeting diverse experimental needs. Of course, depending on the actual situation, one of the storage tanks 4 can also be filled with clean water. For example, before spraying different foliar fertilizers, the operator can connect the water-filled storage tank 4 to the inlet of the electric pump 2 via a switch valve, rinsing the atomizing device 3 with clean water to prevent residues from affecting the experimental results. This design not only improves the flexibility and practicality of the device but also ensures the accuracy and reliability of the experiment.

[0060] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes falling within the meaning and scope of equivalents in this utility model.
