Description

Technical Field

[0001] This utility model belongs to the field of water-soluble fertilizer testing technology, specifically a testing device that facilitates the observation of the water-soluble fertilizer's resistance to hard water. Background Technology

[0002] Water and nutrients are fundamental to crop growth, and their efficient supply creates a favorable growing environment, contributing to improved crop yield and quality. Integrated water and fertilizer management is currently the optimal model for efficient water and nutrient supply. It comprehensively considers soil fertility, the actual needs of crops at different growth stages, and meteorological conditions, using relevant technologies to precisely control the application of water and fertilizer. Its basic principle involves using a pressure irrigation system, through drip irrigation or micro-sprinkler irrigation, to evenly and accurately deliver water-soluble fertilizer (including liquid fertilizer) to the soil around the crop roots, acting directly on the root system. Compared to traditional fertilization methods, this reduces nutrient loss, improves fertilizer utilization efficiency, and significantly saves water, which is particularly significant in arid regions. Furthermore, this fertilization model greatly reduces labor costs, making it especially suitable for large-scale planting areas.

[0003] The following problems exist in the actual use of water-soluble fertilizers. Specifically, because this fertilization method requires transporting the fertilizer solution through pipelines and delivering it to crops via drippers or sprinklers, the fertilizer's solubility is critical; otherwise, it can easily clog drip irrigation or sprinkler irrigation equipment, reducing fertilization efficiency. The solubility of water-soluble fertilizers is related not only to the solubility of the raw materials but also to water hardness. Because water quality varies significantly across regions, especially in areas with high water hardness, fertilizers with poor hardness resistance will exhibit varying degrees of flocculation after dissolving in water. Some of the flocculent material can pass through filters into the pipelines, clogging drippers or sprinklers, leading to reduced fertilization efficiency in that area.

[0004] To avoid the aforementioned adverse effects, it is necessary to develop water-soluble fertilizers with strong resistance to hard water or to classify the hard water resistance of existing water-soluble fertilizers. However, the hard water resistance of existing water-soluble fertilizers is usually tested in test tubes, and when flocculation or precipitation occurs, it is mainly observed by the test personnel with the naked eye and judged based on experience. The above methods result in inaccurate test results. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a test device that facilitates the observation of the hard water resistance of water-soluble fertilizers, thereby solving the technical problems existing in the prior art.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A test apparatus for easily observing the hard water resistance of water-soluble fertilizers, the apparatus comprising:

[0008] Several transparent cylinders for easy observation of the state of water-soluble fertilizer.

[0009] The top opening of the transparent cylinder is equipped with a detachable cylinder cover unit, and the transparent cylinder and the detachable cylinder cover unit are set in a one-to-one correspondence;

[0010] The bottom openings of several transparent cylinders are connected to a detachable base unit.

[0011] The beneficial effects of this utility model are as follows: This utility model uses a detachable base unit to fix several transparent cylinders. During use, water of different hardness can be placed into the transparent cylinders, and water-soluble fertilizer can be added. By comparing and observing, it can be determined whether flocculation and sedimentation occur, thereby improving the accuracy of the judgment results. This utility model uses transparent cylinders to facilitate observation. At the same time, each transparent cylinder has an opening to facilitate cleaning and improve the accuracy of the observation results. Furthermore, the top of the transparent cylinder is equipped with a detachable cylinder cover unit, which allows for convenient addition of water and water-soluble fertilizer. At the same time, closing the detachable cylinder cover unit can prevent the introduction of impurities that may affect the test results.

[0012] Preferably, the outer surface of the transparent cylinder is provided with a maximum water level line and a minimum water level line for easy observation; the maximum water level line is located at 4 / 5 of the height of the transparent cylinder, and the minimum water level line is located at 3 / 5 of the height of the transparent cylinder.

[0013] Preferably, the transparent cylinder includes a top section adapted to the detachable cap unit, an upper section located below the top section, and a lower middle section located below the upper section. The top section is a cylindrical structure with the same diameter at both ends, the upper section is a funnel-shaped structure with a larger diameter at the top and a smaller diameter at the bottom, and the lower middle section is a cylindrical structure with the same diameter at both ends. The highest and lowest water levels are both located in the lower middle section.

[0014] Preferably, the detachable cap unit includes a cap body, the bottom surface of which is provided with a cap protrusion adapted to the top opening of the transparent cylinder, and the connection between the cap protrusion and the cap body is provided with a cap annular groove adapted to the cylinder wall of the transparent cylinder.

[0029] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0030] The following is in conjunction with the appendix Figure 1-4This application provides a further detailed description of the present invention, which is a test device for easily observing the hard water resistance of water-soluble fertilizers. The test device includes several transparent cylinders 1 for easy observation of the water-soluble fertilizer's state. Each transparent cylinder 1 has a detachable cap unit at its top opening, with each transparent cylinder 1 corresponding to a detachable cap unit. The bottom openings of each transparent cylinder 1 are connected to a detachable base unit. This invention is suitable for observing the dissolution of water-soluble fertilizers, particularly for comparative observation of the same water-soluble fertilizer under different hardness water conditions, and for comparative observation of different water-soluble fertilizers under the same hardness water conditions. The comparative observation includes the dissolution rate of the water-soluble fertilizer, whether flocculation and precipitation occur within the solution, and the time it takes for flocculation and precipitation to occur. By comparing and observing these parameters, the properties and characteristics of the water-soluble fertilizer can be determined, providing a basis for the sale and further research and development of the water-soluble fertilizer. This invention is based on a transparent cylindrical body 1, upon which a detachable base unit is provided for easy fixation and convenient subsequent comparative observation. Furthermore, a detachable cap unit is provided at the top of the transparent cylindrical body 1 to prevent the entry of other unknown impurities during static observation and to prevent solution spillage during tilted observation. Moreover, the above-mentioned structure of this invention is easy to assemble, carry, and clean. The detachable cap unit and detachable base unit described in this invention can be detached in a conventional manner, such as snap-fit, threaded connection, or hinged locking connection. It should be noted that existing detachable methods can be used in this invention, but good sealing performance must be ensured during connection. The transparent cylindrical body 1 described in this invention can be made of glass, transparent plastic, etc., ensuring convenient observation and preventing reaction with water-soluble fertilizer solutions.

[0031] Furthermore, the outer surface of the transparent cylinder 1 is provided with a maximum water level line 5 and a minimum water level line 6 for easy observation; the maximum water level line 5 is located at 4 / 5 of the height of the transparent cylinder 1, and the minimum water level line 6 is located at 3 / 5 of the height of the transparent cylinder 1. By setting the maximum water level line 5 and the minimum water level line 6, the water-soluble fertilizer solution to be observed can be kept in approximately the same state, thereby ensuring the accuracy of the observation results.

[0032] Furthermore, the transparent cylinder 1 includes a top section adapted to the detachable cap unit, an upper section located below the top section, and a lower middle section located below the upper section. The top section is a cylindrical structure with the same upper and lower diameters, while the upper section is a funnel-shaped structure with a larger upper diameter and a smaller lower diameter. The lower middle section is a cylindrical structure with the same upper and lower diameters. The highest water level line 5 and the lowest water level line 6 are both located in the lower middle section. In this invention, the diameter of the top section of the cylinder is the same as the diameter of the upper part of the upper section of the cylinder, and the diameter of the lower part of the upper section of the cylinder is the same as the diameter of the lower middle section of the cylinder. The top section of the cylinder is used to fit with the detachable cylinder cap unit to achieve a seal. At the same time, the large diameter of the upper part of the transparent cylinder 1 facilitates the transfer of water-soluble fertilizer solution, thereby reducing the probability of water-soluble fertilizer solution spilling to the outside. The relatively small diameter of the lower middle part of the transparent cylinder 1 enables easy observation (in traditional technology, some fertilizers, such as humic acid products, are dark in color and have a small dilution ratio, requiring observation in containers with larger diameters, such as beakers). (The specific details inside the fertilizer solution cannot be clearly identified); the diameter of the lower part of the transparent cylinder 1 of this invention is generally 1.5-2.3 cm; furthermore, traditional test tubes require a test tube rack for support, but the support frame on the test tube rack obstructs a large area of ​​the test tube, affecting the real-time observation of changes in the internal fertilizer solution. Moreover, the test tubes lack caps and bottom fixing devices, which may allow debris to drift into the test tubes during the experiment, affecting the accurate judgment of the experimental results. Furthermore, the water-soluble fertilizer solution is prone to spillage during transfer, and may even tip over or break during experimental transfer. This invention, compared to existing technologies, features convenient operation and observation.

[0033] Furthermore, the detachable cap unit includes a cap body 2. The bottom surface of the cap body 2 is provided with a cap protrusion 3 that matches the top opening of the transparent cylinder 1. The connection between the cap protrusion 3 and the cap body 2 is provided with a cap annular groove 4 that matches the cylinder wall of the transparent cylinder 1. The detachable cap unit described in this utility model is connected to the top of the transparent cylinder 1 by a snap-fit ​​mechanism. By providing the cap annular groove 4, a good sealing effect can be achieved while the two are properly fitted together.

[0034] Furthermore, the cap body 2 and the cap protrusion 3 are an integral structure, and both are made of elastic material. The elastic material can be any conventional elastic material, such as rubber.

[0035] Furthermore, the detachable base unit includes at least a cover plate 7. The upper surface of the cover plate 7 has several base protrusions 8. The outer diameter of each base protrusion 8 matches the inner diameter of the bottom opening of the transparent cylinder 1. The connection between the base protrusion 8 and the cover plate 7 has an annular groove 9 that matches the wall of the transparent cylinder 1. The base protrusions 8 and the transparent cylinder 1 are arranged in a one-to-one correspondence. The detachable base unit of this invention includes several base protrusions 8 connected to the upper surface of the cover plate 7. During use, the transparent cylinder 1 can be snapped onto the outside of the base protrusions 8 to achieve sealing and fixation.

[0036] Furthermore, the distance between the base annular groove 9 and the adjacent base annular groove 9 is 3 to 5 cm.

[0037] Furthermore, the cover plate 7 and the several base protrusions 8 are an integral structure, and all are made of elastic material. The elastic material can be any conventional elastic material, such as rubber.

[0038] Furthermore, the detachable base unit also includes a fixing plate 10, the upper surface of which is fixedly connected to the lower surface of the cover plate 7. The fixing plate 10 in this invention mainly serves as a counterweight. Preferably, the lower surface of the fixing plate 10 may be provided with anti-slip texture to facilitate the upright positioning of the transparent cylinder 1 for easy observation.

[0039] Furthermore, the fixing plate 10 is made of stainless steel.

[0040] The specific working process of this utility model is as follows: The prepared hard water mother liquor is diluted according to requirements to prepare aqueous solutions of different hardness. Then, the water-soluble fertilizer is diluted and dissolved using the above aqueous solutions according to an appropriate water-to-fertilizer ratio. Taking six transparent cylinders 1 as an example (the hardness resistance of ordinary water-soluble fertilizer is generally around 25 degrees, while the water hardness in some areas of my country exceeds 50 degrees; based on a 5-degree gradient, at least six transparent cylinders 1 are needed for testing), the bottom of the transparent cylinder 1 is fixed to the base protrusion 8. After connection, the diluted fertilizer solution is passed through the transparent cylinder 1. The solution is added to different transparent cylinders 1 according to the water level requirements through the top opening. Finally, the cap protrusion 3 of the detachable cap unit is secured to the top opening of the transparent cylinder 1. Alternatively, prepared aqueous solutions of different hardnesses are directly added to different transparent cylinders 1 through the top opening according to the water level requirements. Then, an equal amount of liquid fertilizer is added to each transparent cylinder 1 according to an appropriate water-to-fertilizer ratio. The cap protrusion 3 of the detachable cap unit is secured to the top opening of the transparent cylinder 1, and the changes in the fertilizer solution inside the transparent cylinder 1 are observed after standing. After the above work is completed, the changes in the fertilizer solution inside the transparent cylinder 1 are observed after standing. The observation mainly records the time and compares the water-soluble fertilizer solutions in multiple transparent cylinders 1. For example, if the fertilizer solution in the transparent cylinder 1 remains clear and transparent, it proves that the water-soluble fertilizer can withstand the water hardness. If flocculation or sedimentation occurs inside the transparent cylinder 1, it proves that the water-soluble fertilizer's resistance to hard water is less than the hardness of the water, indicating that the water-soluble fertilizer cannot be used under this water quality condition. The above method can accurately determine the hard water resistance of the same water-soluble fertilizer; or accurately determine the hard water resistance of different water-soluble fertilizers under the same water quality conditions. After use, open the detachable cap unit, pour out the water-soluble fertilizer solution, then disassemble the detachable base unit, and finally clean the transparent cylinder 1, the detachable cap unit, and the detachable base unit respectively for future use.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
